Description

Technical Field

[0001] This utility model relates to the field of rotary tiller technology, specifically to a rotary tillage combined operation tillage depth angle adjustment device. Background Technology

[0002] Rotary tillage is a highly efficient agricultural farming method that combines various agricultural machines. Based on a rotary tiller, it is equipped with several auxiliary devices to integrate multiple functions, thereby improving work efficiency and reducing energy consumption. During the rotary tillage process, the depth of the rotary tiller needs to be adjusted according to the soil properties or crop selection to achieve better tillage results.

[0003] According to the Chinese patent publication number CN202663738U, "A Deep Tillage and Rotary Tillage Combined Operation Tillage Depth Angle Adjustment Device", it mainly describes that by conveniently adjusting the angle and depth, the angle and depth of rotary tillage and plowing can be easily adjusted to suit the needs of different land types and arable land plowing.

[0004] However, rotary tillers are usually towed by tractors when in use. Therefore, when the tractor or towing vehicle starts to move, the rotary tiller needs to be lifted first and then gradually lowered until the blades of the rotary tiller enter the soil and reach a certain depth to achieve tillage. In order to avoid the rotary tillage structure lifting the towing mechanism, the rotary tiller usually chooses to adjust the tillage depth during the tillage process. However, when adjusting the tillage depth, the rotary tiller will collide with stones in the soil, which will cause the stability of the adjustment mechanism to deteriorate, thus affecting the tillage quality.

[0005] Therefore, a rotary tillage combined operation tillage depth angle adjustment device is proposed to solve the problem that when the rotary tiller is adjusting the tillage depth, it will collide with stones in the soil, which will cause the adjustment mechanism to become less stable and thus affect the tillage quality. Utility Model Content

[0006] The technical problem to be solved by this utility model is that when the rotary tiller is adjusting the tillage depth, it will collide with stones in the soil, which will cause the stability of the adjustment mechanism to deteriorate and thus affect the tillage quality. Therefore, a tillage depth angle adjustment device for combined rotary tillage operation is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a rotary tillage combined operation tillage depth angle adjustment device, including a tractor and a connecting plate. A clamping plate is sleeved on the connecting plate, and a positioning rod is threadedly connected to the clamping plate. The positioning rod is inserted into the clamping plate. A first groove is opened on the clamping plate. The clamping plate is located in the first groove and contacts a clamping frame. A drive motor is fixedly connected to one side of the clamping frame. A plow roller is fixedly connected to the output end of the drive motor. Support rods are fixedly connected to the four sides of the upper part of the clamping plate. An auxiliary plate is fixedly connected to the upper end of the support rod. An electric push rod is fixedly connected to the bottom end of the auxiliary plate. A pressure plate is fixedly connected to the bottom end of the electric push rod. A limit rod is movably inserted into the pressure plate. A spring is sleeved on the bottom side of the limit rod. The limit rod is fixedly connected to the clamping frame. The clamping frame is fixedly connected to the limit rod. A limit frame is fixedly connected to the upper end of the limit rod. The limit frame is fixedly connected to the clamping frame. A distance sensor is fixedly connected to the bottom end of the auxiliary plate. The distance sensor corresponds to the limit frame.

[0008] As a preferred technical solution of this utility model, an auxiliary rod is fixedly connected to the bottom end of the auxiliary plate, and a support plate is fixedly connected to the bottom end of the auxiliary rod. The bottom end of the support plate corresponds to the limiting frame. By setting the auxiliary rod and the support plate, support can be provided for the electric push rod.

[0009] As a preferred technical solution of this utility model, a pad is provided inside the limiting frame and the pad corresponds to the pressure plate. The pad is fixedly connected to the upper side of the card frame. By setting the pad in conjunction with the limiting rod and the spring, the stability can be increased.

[0010] As a preferred technical solution of this utility model, both sides of the card frame are in contact with spheres, and the spheres are rotatably embedded in the first groove. By setting the spheres, the friction of the card frame moving up and down is reduced.

[0011] As a preferred technical solution of this utility model, the card frame is fixedly connected to four sides on the upper end, and the connecting rods are movably inserted into the auxiliary plate. By setting the connecting rods and the auxiliary plate, the stability of the card frame moving up and down can be increased.

[0012] This utility model has the following advantages: the extension of the electric push rod can drive the locking mechanism to move up and down, thereby changing the depth of the plow roller in the soil. Then, a limiting frame is set between the electric push rod and the locking frame to limit the pressure plate. Under the action of the spring and the pad, a buffering effect can be provided to reduce the instability caused by the rotary tiller's adjustment structure being hit. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The rotary tillage combined operation tillage depth angle adjustment device shown includes a tractor 1 and a connecting plate 2. A clamping plate 4 is sleeved on the connecting plate 2, and a positioning rod 3 is threadedly connected to the clamping plate 4. The positioning rod 3 is inserted into the clamping plate 4, and the clamping plate 4 is locked on the connecting plate 2 by the positioning rod 3. At the same time, the plow blade on the bottom side of the plow roller 7 is in contact with the soil. The extension of the electric push rod 10 can cause the clamping frame 6 to move down, thereby adjusting the depth of the plow blade in the soil. A first groove 5 is opened on the clamping plate 4, and the clamping plate 4 is located in the first groove 5 and contacts the clamping frame 6. A drive motor is fixedly connected to one side of the clamping frame 6, and the output end of the drive motor is fixedly connected to the plow roller 7. Support rods 8 are fixedly connected to the four sides of the upper end of the clamping plate 4, and the upper end of the support rods 8 is fixedly An auxiliary plate 9 is connected to the auxiliary plate 9. An electric push rod 10 is fixedly connected to the bottom of the auxiliary plate 9. A pressure plate 11 is fixedly connected to the bottom of the electric push rod 10. A limit rod 12 is movably inserted into the pressure plate 11. A spring is sleeved on the bottom side of the limit rod 12. The limit rod 12 is fixedly connected to the frame 6. The frame 6 is fixedly connected to the limit rod 12. A limit frame 13 is fixedly connected to the upper end of the limit rod 12. The limit frame 13 is fixedly connected to the frame 6. A distance sensor 14 is fixedly connected to the bottom of the auxiliary plate 9. The distance sensor 14 is connected to the electric push rod 10 through a wire. The distance sensor 14 corresponds to the limit frame 13. By setting the distance sensor 14 to monitor the distance between the auxiliary plate 9 and the frame 4, the height of the plow roller 7 is controlled.

[0019] Among them, the bottom end of the auxiliary plate 9 is fixedly connected to the auxiliary rod 15, and the bottom end of the auxiliary rod 15 is fixedly connected to the support plate 16. The bottom end of the support plate 16 corresponds to the limit frame 13. By setting the auxiliary rod 15 and the support plate 16, the electric push rod 10 can be protected.

[0020] The limiting frame 13 is provided with a pad 17, which corresponds to the pressure plate 11. The pad 17 is fixedly connected to the upper side of the card frame 6. The pad 17 is made of rubber. By setting the pad 17, the buffer is increased and the wear of the electric push rod 10 is reduced.

[0021] The card frame 6 has spheres 18 on both sides, and the spheres 18 rotate and are embedded in the first groove 5. By setting the spheres 18, the friction between the first groove 5 and the card frame 6 is reduced.

[0022] Among them, the card frame 6 is fixedly connected to four sides of the upper end with connecting rods 19. The connecting rods 19 are movably inserted into the auxiliary plate 9. By setting the connecting rods 19 in conjunction with the auxiliary plate 9, the card frame 6 can be limited, thereby improving the stability of the movement of the card frame 6.

[0023] Working principle: The tractor 1 moves the clamping plate 4 and clamping frame 6, and then the plow blade contacts the soil. During the movement of the tractor 1, the electric push rod 10 is extended, and the clamping frame 6 and plow blade move down to a certain depth in the soil. At this time, the distance sensor 14 provides monitoring and controls the extension and retraction of the electric push rod 10. During the plowing process, the limiting rod 12 and pad 17 in the limiting frame 13 provide buffering to reduce the wear of the electric push rod 10, thereby improving the stability of the rotary tiller's adjustment structure when it is subjected to collision.
