Description

Technical Field

[0001] This utility model belongs to the technical field of soil-raising machine equipment, specifically, it relates to a soil-raising machine that reduces the operating force when changing rows at the edge of the field. Background Technology

[0002] In traditional ridging machines, the rear drive wheel transmission housing is typically designed to be perpendicular to the ground. This design has significant drawbacks when the machine is changing rows at the edge of the field after completing one ridge. Difficulty in changing lanes: Due to the vertical setting of the drive unit and the main body of the traditional ridger, the center of gravity of the ridger is not properly distributed when turning. This requires the operator to apply a lot of force to turn, especially in soft soil or sloping conditions, where changing lanes is even more difficult. At the same time, the operator also needs to lift the front end to cooperate with the turning while under great pressure, which lacks safety.

[0003] Inefficiency: To improve line switching performance, some models adjust the center of gravity by adding counterweights. However, this method increases the overall weight of the equipment, which not only increases energy consumption but also reduces operational flexibility, further affecting the working efficiency of the soil-laying machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a soil-raising machine that reduces the operating force when changing rows at the edge of the field. Without adding counterweights to further increase the weight of the machine, the operator can more easily lift the front end of the machine. When changing rows, the machine can turn around on the spot by relying only on the two rear drive wheels. This improves the flexibility of the soil-raising machine and enhances its adaptability to small tobacco fields in hilly and mountainous areas.

[0005] A soil-cultivating machine that reduces operating force when changing rows at the edge of a field includes a soil-cultivating machine body. The input end of the rear wheel of the soil-cultivating machine body is connected to the output end of a drive device via a chain drive assembly. The drive device is mounted on the soil-cultivating machine body. The soil-cultivating machine body is equipped with a first belt clutch handle. The output end of the first belt clutch handle is configured to correspond to the conveyor belt of the first transmission module. The first belt clutch handle is used to press down on the conveyor belt of the first transmission module but not to press it tightly.

[0006] Furthermore, the driving device includes a first transmission module, a second transmission module, and a chain transmission assembly. The output end of the first transmission module is fixedly connected to the input end of the second transmission module. The output end of the second transmission module is connected to the rear wheel of the hill-climbing machine body through the chain transmission assembly. The included angle between the center of the output end of the second transmission module and the center of the rear wheel of the hill-climbing machine is 5-13°.

[0007] Furthermore, the angle between the center of the output end of the second transmission module and the center of the rear wheel of the soil-cultivating machine is preferably 9°.

[0008] Furthermore, it also includes a second belt clutch handle, which is installed on the upper side of the body of the soil-cultivating machine. The output end of the second belt clutch handle is set to correspond to the conveyor belt of the first transmission module, and the output end of the second belt clutch handle can press down on the conveyor belt of the first transmission module.

[0009] Furthermore, the frame of the rear wheel of the soil-cultivating machine body is fixedly installed with the connecting plate. The connecting plate is provided with mounting holes, and the connecting plate and the frame are bolted together. The connecting plate is fixedly connected to the rotating shaft roller, and the rotating shaft roller is fixedly connected to the gearbox corresponding to the input end of the rear wheel of the soil-cultivating machine body.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are: The original drive device of this utility model is connected to the main body of the ridging machine by a 9° vertical offset. The operator lifts the front end of the main body of the ridging machine with both hands, leaving only the rear drive wheels in contact with the ground. At this time, the operator operates the drive device to turn the two rear drive wheels of the main body of the ridging machine around and move to the next row of ridges to complete the row change operation. This allows the operator to lift the front end of the machine more easily without adding counterweights to further increase the weight of the machine. When changing rows, the operator can turn around on the spot by turning the two rear drive wheels alone, which improves the flexibility of the ridging machine and enhances its adaptability to small tobacco fields in hilly and mountainous areas.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: A soil-cultivating machine that reduces operating force when changing rows at the edge of a field includes a soil-cultivating machine body 5. The input end of the rear wheel of the soil-cultivating machine body 5 is connected to the output end of a drive device 1 through a chain transmission assembly 101. The drive device 1 is mounted on the soil-cultivating machine body 5. The soil-cultivating machine is equipped with a first belt clutch handle 3. The output end of the first belt clutch handle 3 is configured to correspond to the conveyor belt of the first transmission module 103. The first belt clutch handle 3 is used to press down on the conveyor belt of the first transmission module 103 but not to press it tightly. The soil-cultivating machine is equipped with a second belt clutch handle 10. The output end of the second belt clutch handle 10 is set corresponding to the conveyor belt of the first transmission module 103. The second belt clutch handle 10 is used to press down the conveyor belt of the first transmission module 103, so that the conveyor belt of the first transmission module 103 can be pressed to ensure that the rear wheel is in a rotating state. When the second belt clutch handle 10 releases the conveyor belt of the first transmission module 103, the engine output shaft rotates freely and the soil-cultivating machine stops moving.

[0014] The first belt clutch handle 3 and the second belt clutch handle 10 both use existing products. The principle is that the clutch cable branches off into the clutch linkage cable through the splitter. When the handle is squeezed, the tension of the clutch cable is simultaneously transmitted to the clutch linkage cable, triggering the clutch to disengage. When the handle is released, the clutch is reset under the action of the reset spring. The second belt clutch handle 10 fully presses the transmission belt of the first transmission module 103, and is a clutch that controls the power on / off of forward and backward movement. The first belt clutch handle 3 is not fully pressed, and the clutch is relatively loose. It is a clutch that provides reverse torque but does not allow the rear wheel to rotate.

[0015] The rear wheel of the soil-cultivating machine body 5 is the drive wheel located on the lower side of the drive device 1.

[0016] In this embodiment, the drive device 1 uses a gasoline engine as the power source. The gasoline engine transmits power to the input end of the rear wheel through the first transmission module 103, the second transmission module 102, and the chain drive assembly 101, thereby rotating the rear wheel and ultimately moving the body 5 of the soil-cultivating machine. When it is necessary to stop the rotation of the rear wheel of the body 5 of the soil-cultivating machine, simply operate the second belt clutch handle 10 to release the conveyor belt of the first transmission module 103, thereby cutting off the power transmission and stopping the rotation of the rear wheel. The drive device 1 includes a first transmission module 103, a second transmission module 102, and a chain drive assembly 101. The output end of the first transmission module 103 is fixedly connected to the input end of the second transmission module 102. The output end of the second transmission module 102 is connected to the rear wheel of the body 5 of the soil-cultivating machine through the chain drive assembly 101. The angle between the center of the output end of the second transmission module 102 and the center of the rear wheel of the soil-cultivating machine is 5-13°.

[0017] The angle between the center of the output end of the second transmission module 102 and the center of the rear wheel of the reamer is preferably 9°.

[0018] It also includes a second belt clutch handle 10, which is installed on the upper side of the soil-cultivating machine body 5. The output end of the second belt clutch handle 10 is set to correspond to the conveyor belt of the first transmission module 103, and the output end of the second belt clutch handle 10 can press down on the conveyor belt of the first transmission module 103.

[0019] The second transmission module 102 is driven by a sprocket and chain. One side of the chain is connected to the frame of the hilling machine body 5 via a limiting component 4. The limiting component 4 includes a support block 401, an elastic element 402, and a fixing block 403. The support block 401 is slidably connected to the chain. The support block 401 is rotatably connected to one end of the elastic element 402. The other end of the elastic element 402 is rotatably connected to the fixing block 403. An even number of fixing blocks 403 are fixed to the frame of the hilling machine body 5. The Shanghai-made roller 6 is fixedly installed, and the bracket of the roller 6 is fixed on the frame of the main body 5 of the soil-cultivating machine. The ball of the roller 6 abuts against the elastic element 402. In this way, the roller 6 can provide stable support for the elastic element 402. At the same time, the support block 401 slides with the chain, which can effectively reduce the shaking and deviation during the chain transmission process. When the elastic element 402 is subjected to the force brought by the chain transmission and the abutting force of the roller 6, it can undergo elastic deformation, which plays a role in buffering and adjustment, further ensuring the smooth operation of the entire transmission process.

[0020] The frame of the rear wheel of the soil-cultivating machine body 5 is fixedly installed with the connecting plate 8. The connecting plate 8 is provided with mounting holes 9. The connecting plate 8 and the frame are bolted together. The connecting plate 8 is fixedly connected to the rotating shaft roller 7. The rotating shaft roller 7 is fixedly connected to the gearbox corresponding to the input end of the rear wheel of the soil-cultivating machine body 5. In this embodiment, the gearbox is a transmission mechanism that drives the rear wheel of the soil-cultivating machine body 5. The gearbox is an existing product, and the gear transmission principle inside it adopts the existing principle, which will not be described in detail and will not be shown in the figure.

[0021] In this embodiment, both the first transmission module 103 and the second transmission module 102 adopt belt and pulley structure transmission. In actual use, when the motor starts, the power passes through the first transmission module 103 and the second transmission module 102 in sequence, and then is transmitted to the rear wheel through the chain transmission assembly 101, driving the soil-cultivating machine body 5 to move forward. The specific angle design between the output end of the second transmission module 102 and the center of the rear wheel makes it easier to turn. In this embodiment, the weight of the entire machine excluding the rear wheel is 241 kg. The distance between the handle of the first belt clutch handle 3 and the center of the rear wheel is 1500 mm. When the drive device 1 is vertically connected to the main body of the soil-lifting machine, the resistance arm of the distance between the center of gravity of the entire machine and the center of the rear wheel is 361 mm. At this time, the operator needs to lift at least 58 kg to lift the machine. When the offset is 5°, the resistance arm of the center of gravity is 337 mm, and the operator needs to lift 54.1 kg. When the offset is 9°, the resistance arm of the center of gravity is 318 mm, and the operator needs to lift 51 kg. When the offset is 13°, the resistance arm of the center of gravity is 299 mm, and the operator needs to lift 48 kg. In order to ensure the stability of the entire machine during operation, it is confirmed that the drive device 1 is offset backward by 9°. This ensures that the operating force when the operator lifts the front of the machine is reduced compared to the vertical connection and the 5° offset, and also ensures that the center of gravity of the soil-lifting machine is not too far back, making it more stable in working condition than at 13°.

[0022] In this embodiment, in addition to the set of second belt clutch handles 10 on the drive unit 1, a new set of first belt clutch handles 3 is added below the operator's lifting position. The newly added first belt clutch handles 3 are adjusted so that they do not completely compress the transmission belt of the first transmission module 103 of the drive unit 1. This ensures that when the first belt clutch handles 3 are squeezed, there is still not enough power to drive the soil-covering machine forward, and the soil-covering machine will remain stationary. When the soil-covering machine reaches the end of the ridge, the second belt clutch handles 10 of the drive unit 1 are released to stop. At this time, the first belt clutch handles 3 are squeezed. Since the drive unit 1 is not strong enough to make the rear wheel rotate forward, the torque provided by the drive unit 1 tends to make the drive unit 1 rotate in the opposite direction. By continuously squeezing the first belt clutch handles 3, this reverse torque will continue to exist, which can reduce the operating force required for the operator to lift the front end of the soil-covering machine.

[0023] The method of using this utility model is as follows: When the gasoline engine of the drive unit 1 is started, the power passes through the first transmission module 103 and the second transmission module 102 in sequence, and then through the chain transmission assembly 101 to the rear wheel, driving the body of the soil-cultivating machine 5 to move forward. During the movement, due to the 9° angle design between the output end of the second transmission module 102 and the center of the rear wheel, the soil-cultivating machine is easier to turn, and the operator can control the direction of travel of the soil-cultivating machine more easily. When the ridging machine needs to change lanes at the end of the ridge, the operator first releases the second belt clutch handle 10 on the drive unit 1. At this point, power transmission is cut off, the rear wheel stops rotating, and the ridging machine stops. Then, the operator squeezes the first belt clutch handle 3 located below the lifting point. Because this handle is adjusted so as not to fully engage the chain drive assembly 101 of the drive unit 1, the torque provided by the drive unit 1 tends to cause the drive unit 1 to rotate in the opposite direction when the drive unit 1 is insufficient to rotate the rear wheel forward. This continuous reverse torque effectively reduces the operating force required for the operator to lift the front end of the ridging machine, allowing the operator to lift the front end of the ridging machine more easily for turning operations. After completing the turn, release the first belt clutch handle 3 and operate the second belt clutch handle 10 again to return it to its original position. Power is then transmitted back to the rear wheel, and the hiller continues to move forward to carry out the next row of hilling operations.

[0024] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
