Crawler Multifunctional Self-propelled Rotary Tiller

     With the continuous increase of family farm farming and large-scale planting in reclamation areas, farmers have higher and higher requirements for modern farming machinery. The use of rotary tillers has greatly improved agricultural production efficiency, but it also makes cultivated land face a serious problem-deep mud feet. Deep mud feet affect the passing performance of paddy fields and crop growth, and most importantly, affect the increase in crop yields. It is gratifying that the continuous upgrading of rotary tillers in recent years has gradually improved this problem. Among them, the most representative crawler multi-function self-propelled rotary tiller does not harm the tillage layer structure of paddy fields, has an obvious ecological protection effect on paddy fields, and can make rice fields enter a virtuous cycle. From the perspective of the flatness of the land after plowing, fuel consumption, and work efficiency, it has unparalleled advantages over traditional rotary tillers and is vigorously promoted. It is known as the rotary tiller that "wears boots to go into paddy fields". The emergence of crawler self-propelled rotary tillers also represents the future development direction of paddy field cultivation.

Overview of the practicality of crawler multifunctional self-propelled rotary tiller

     The crawler self-propelled rotary tiller has the characteristics of "one machine for multiple uses". It is equipped with a fertilizing device, a furrowing device, and a lifting device. It can greatly save farming time and improve farming efficiency during the operation season. That is, it can be driven by itself and complete the operations of rotary tillage, furrowing, ridge formation, sowing, fertilization, etc. at one time, realizing multi-process compound operations. In particular, the superior performance of crawler self-propelled rotary tiller in furrowing and ridge formation can achieve the effect of multiple plowing and harrowing in one operation. The above work can be completed by simply replacing different machines or blades. In addition to paddy fields, crawler self-propelled rotary tillers are also applicable to dry land. Compared with traditional large rotary tillers and micro rotary tillers towed by traditional tractors, crawler self-propelled rotary tillers have wider functions, higher efficiency, and more convenient operation. Traditional large rotary tillers do not have driving power themselves and cannot operate independently for farming. They must be equipped with a tractor. Only by relying on the drive of the tractor can the entire rotary tillage process be truly completed. Crawler self-propelled rotary tillers are truly self-propelled all-in-one machines.

   Crawler self-propelled rotary tillers solve the problem of traditional wheeled machines causing damage to paddy fields, so that the soil is no longer "injured". Traditional large rotary tillers rely on wheeled tractors to plow the fields, which are highly efficient, but have a fatal flaw. The large tires of the tractor have a small contact area with the ground. The tractor itself is very heavy. When walking in paddy fields under high pressure per unit area, the tires can easily sink deep into the hard mud layer, rolling out two deep grooves and turning up a thick layer of raw mud, causing the mature mud layer and the raw mud layer to mix together, making them uneven and destroying the soil structure of the tillage layer. Every time the tillage is done, the tillage mud layer deepens once, and this vicious cycle causes water and fertilizer leakage. Survey results show that the mud feet of paddy fields that are continuously plowed with wheeled tractors and rotary tillers generally deepen, that is, the paddy field has poor passing performance. The consequence is that the soil ecology of farmland, especially paddy fields, is seriously damaged, and eventually the tillage machinery cannot be put into the field for operation, affecting the growth of crops. To a certain extent, the good fields will become barren. The self-propelled rotary tiller is a complete machine that does not rely on the power of a tractor. It has a small overall size and light weight, and puts little pressure on farmland. The walking device uses rubber tracks, which have a large ground contact area and low average ground contact pressure. It does not damage the bottom of the field during operation, and ensures the stability of paddy field tillage depth without destroying the tillage layer, effectively improving the tillage and soil thinning effect, and making up for the shortcomings of traditional rotary tillers using wheeled tractors in paddy field passing performance. Its advantages in tillage are more obvious in the northern plains.

    The crawler multifunctional self-propelled rotary tiller makes the cultivated land have good flatness. When the traditional large rotary tiller is in operation, the two deep grooves rolled out by the two tires will cause the mud bottom of the paddy field to be uneven in depth, and the depth difference is generally 5 or 6 cm, which seriously affects the quality of the machine planting. The seedlings planted by the transplanter will be planted deep when encountering a deep mud bottom and shallow when encountering a shallow mud bottom, which will eventually affect the growth of the seedlings and reduce the yield. The crawler part of the crawler self-propelled rotary tiller is made of rubber, with low ground pressure. It will not sink into the hard mud layer when walking in the paddy field. Its front balance frame and other structures make the walking force uniform, and it will not roll out two deep grooves during tillage, and will not damage the mud foot depth of the farmland. The tillage depth of the land is moderate and consistent, not easy to sink, the dry farming soil is fine and uniform, the water farming mud is rotten, and the weeds and vegetation are buried in the mud with high quality. After tillage, it has good flatness and does not need to be leveled again with other leveling machines. The tillage effect is significantly better than other tillage machines. The use of crawler self-propelled rotary tiller consumes less fuel and is more in line with the trend of energy conservation and emission reduction.

Exquisite workmanship, focusing on mechanical production and manufacturing.

Key points for operating crawler self-propelled rotary tillers

1. Start. When starting a crawler self-propelled rotary tiller, the first thing to do is to gradually transition from low speed and no load to high speed and full load. You cannot use high speed and full load immediately. It takes about 3-5 minutes to reach the predetermined speed before the unit can start. After starting, the crawler self-propelled rotary tiller should be driven slowly at a low speed, which can not only reduce the wear of the machine parts, but also make the soil clods fine and ensure the quality of the operation.
2. Precautions for driving. During the driving of the crawler self-propelled rotary tiller, pay attention to observing the soil crushing and tillage depth. The load weight needs to be strictly controlled throughout the whole process to avoid overloading and affecting the life of the equipment; if there are abnormal phenomena during operation, such as metal knocking, noise, the rotary tiller blade roller cannot turn, or the rotary tiller throws out large clods of soil intermittently, the engine should be turned off immediately, the car should be stopped for inspection and adjustment, and the fault should be eliminated before restarting to continue the operation.
3. Turning and reversing. It is strictly forbidden to make sharp turns, and it is forbidden to work when turning at the head of the field. When turning, the power throttle should be reduced, and the rotary tiller should be raised to make the blade leave the ground. To prevent damage to the machine parts when reversing, the rotary tiller should be lifted to the highest position and the working clutch should be separated.
4. About maintenance. The principle of maintenance of rotary tillers is "prevention is more important than treatment, maintenance is more important than repair". After each shift, check whether the machete, latch and cotter pin and other vulnerable parts are damaged; check whether the power, gearbox, transmission box and bearing are lack of oil; check the tightness of the connecting bolts and tighten them, replace the damaged parts and add the engine oil in time.

Fault repair

1. The rotary tiller is under heavy load. This is generally caused by excessive tillage depth, heavy and hard soil. The solution is to reduce the tillage depth (the blade roller limit assembly can be adjusted to the optimal position) and reduce the forward speed of the unit.
2. The rotary tiller jumps when working. This is generally caused by the soil being too hard or the blade being installed incorrectly. The solution is to reduce the forward speed of the unit and install the blade correctly
3. There is a metal knocking sound when the rotary tiller is working. The main reason is that the blades on both sides of the blade roller shaft collide with each other after deformation or the blade fixing screws are loose. The solution is to correct or replace severely deformed parts and tighten the loose nails.
4. There is noise in the blade roller gearbox. This is generally caused by foreign matter falling into the gear during installation, or damage to the bearings and gear teeth.
The solution is to try to remove foreign matter or replace bearings and gears.
5. The rotary tiller throws out large clods of soil intermittently. The main reasons are that the blade is bent, deformed, broken, lost or severely worn. The solution is to correct or replace the blade.
6. The rotary tiller blade roller cannot rotate. The main reasons are that the working belt is too loose or the working clutch is slipping, the gear or bearing is stuck, etc. The solution is to tighten the working belt, adjust the working clutch clearance to make it firmly and reliably engaged, and replace or repair the damaged gear or bearing.
