Description

Technical Field

[0001] This utility model relates to a disc plow, and more specifically, to a hydraulic horizontal swing bidirectional disc plow. Background Technology

[0002] The disc plow uses a rotating concave disc as its working component. During operation, the plow blades rotate to till the soil. It is particularly suitable for tilling complex farmland with abundant weeds, upright stems, high soil resistance, or stones. It is a new type of soil tillage tool. The disc plow is powered by a tractor. As the tractor moves forward, the traction force is transmitted to the disc harrow through the traction device. Under the combined action of the soil and the traction force, the appropriate depth of the implement is achieved by controlling the extension and retraction of the hydraulic cylinder and adjusting the spring. Through the shearing and frictional force of the disc harrow blades at a certain angle, the relative displacement of the soil surface is caused, which completes the actions of cutting grass roots and crop residues, stirring and turning the topsoil, and achieving the purpose of stubble removal, soil breaking and loosening.

[0003] To enable a disc plow to till the soil in the same direction during its back-and-forth operation, the plow needs to be able to swing back and forth, and the plowshare needs to be able to turn at a certain angle. For example, patent document CN 201920043309.7 discloses a horizontally swinging bidirectional disc plow, which achieves back-and-forth tilling by swinging the plowshare. However, in this structure, during the rotation of the plowshare at a certain angle, the drive rod and drive block drive the reversing rod to move, thus achieving the rotation of all plowshares. In actual use, the drive rod is very prone to breakage, seriously affecting the progress of soil tilling. Therefore, this utility model proposes a durable hydraulic horizontally swinging bidirectional disc plow with a swing steering mechanism. Summary of the Invention

Multiple plow disc mechanisms are present. The longitudinal beam is mounted on the frame, and the multiple plow disc mechanisms are evenly spaced along the longitudinal beam. The tail wheel mechanism is located at the rear end of the longitudinal beam. A suspension seat for connection to traction machinery is located at the front end of the frame. The swing steering mechanism is mounted on the frame and is used to drive the longitudinal beam to swing and the plow disc mechanisms to rotate. A square tube seat is fixed at the rear end of the frame. Plow legs and plow leg upper sleeves are mounted on the plow disc mechanisms. The plow leg upper sleeves are fixed to the upper ends of the plow legs. The machine is equipped with fixed ear plates, and all ear plates on the plowshare mechanism are hinged to the steering linkage; the swing steering mechanism consists of a swing cylinder and a central rotating shaft; the longitudinal beam passes laterally through the square tube seat, and the central rotating shaft passes vertically through the square tube seat and is fixedly connected to the longitudinal beam; one end of the swing cylinder is hinged to the middle of the frame, and the other end is hinged to the upper end of the central rotating shaft; the machine is characterized in that: the square tube seat is connected to the upper end of the plow leg on a plowshare mechanism via a guide shaft and a guide sleeve; the guide sleeve is horizontally set, and the outer wall of the guide sleeve is fixed to the upper end of a plow leg; one end of the guide shaft is hinged to the square tube seat, and the other end of the guide shaft passes through the guide sleeve.

[0006] The present invention relates to a hydraulic horizontal swing bidirectional disc plow, wherein the frame is composed of a U-shaped frame, a front support rod, and a middle support rod. The front support rod, the middle support rod, and the square tube seat are respectively fixed to the front end, the middle part, and the rear end of the U-shaped frame. An arc plate is fixed to the front end of the U-shaped frame, and the arc plate is on a circle with the central axis as the center. The front end of the longitudinal beam is provided with a slot that can be inserted into the arc plate.

[0007] The present invention relates to a hydraulic horizontal swing bidirectional disc plow, wherein the plow disc mechanism consists of a plow disc, plow legs, plow leg sleeves, and a plow leg upper sleeve. The plow disc is fixed to the lower end of the plow legs by bearings. The plow leg sleeves are set through the longitudinal beam and fixed on the longitudinal beam. The plow legs are set through the plow leg sleeves, and the plow leg upper sleeves are fixed to the upper end of the plow legs.

[0008] This utility model discloses a hydraulic horizontal swing type bidirectional disc plow. The tail wheel mechanism consists of a tail wheel cylinder, a vertical shaft, a tail wheel sleeve, a tail wheel support leg, and a tail wheel. The vertical shaft is rotatably mounted at the rear end of the longitudinal beam, and the tail wheel sleeve is fixed on the vertical shaft.

The front end of the tail wheel support leg is hinged to the tail wheel sleeve, and the tail wheel is located at the rear end of the tail wheel support leg.

[0009] The present invention relates to a hydraulic horizontal swing bidirectional disc plow, wherein both sides of the front end of the frame are provided with support legs for support.

[0010] The beneficial effects of this utility model are as follows: The hydraulic horizontal swing-type bidirectional disc plow of this utility model is provided with a frame, longitudinal beam, multiple plow disc mechanisms, a tail wheel mechanism, and a swing steering mechanism.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 7 As shown, the front view, rear view, left view, right view, top view, bottom view, and perspective view of the hydraulic horizontal swing bidirectional disc plow of this utility model are given respectively. Figure 8 and Figure 9 All of these drawings provide perspective views of the frame and the swing steering mechanism of this utility model. The hydraulic horizontal swing bidirectional disc plow shown consists of a frame 1, a longitudinal beam 2, a plow disc mechanism 3, a tail wheel mechanism 4, and a swing steering mechanism 5. The frame 1 serves to fix and support the plow. The frame 1 shown consists of a U-shaped frame 9, a front support rod 10, a middle support rod 11, and a square tube seat 12. The front support rod 10, the middle support rod 11, and the square tube seat 12 are respectively fixed to the front end, the middle part, and the rear end of the U-shaped frame 9. An arc plate 13 is also fixed to the front end of the U-shaped frame 9.

[0025] The plow mechanism 3 shown is a plurality of plow mechanisms 3, which are evenly spaced on the longitudinal beam 2, such as... Figure 10The diagram shows a perspective view of the plowshare mechanism 3 of this invention. The plowshare mechanism 3 consists of a plowshare 19, plow legs 20, plow leg sleeves 21, and an upper plow leg sleeve 22. The plowshare 19 is disc-shaped and is fixed to the lower end of the plow legs 20 via bearings. The plowshare 19 can rotate during soil cutting to reduce soil resistance. The plow legs 20 are cylindrical, and the upper plow leg sleeve 22 is fixed to the upper end of the plow legs 20. The plow legs 20 are inserted into the plow leg sleeves 21 and can rotate freely within them. The plow leg sleeves 21 pass through and are fixedly connected to the longitudinal beam 2. Thus, the rotation of the upper plow leg sleeve 22 drives the plow legs 20 and plowshare 19 to rotate synchronously.

[0026] Ear plates 23 are fixed on the upper sleeve 22 of the plow leg. The ear plates 23 on the upper sleeve 22 of the plow leg of all the plow disc mechanisms 3 are hinged to the steering linkage 7. In this way, the steering linkage 7 connects all the upper sleeves 22 of the plow leg through the ear plates 23, so as to realize the synchronous rotation of the plow disc 19 and the plow leg 20 on all the plow disc mechanisms 3.

[0027] The swing steering mechanism 5 shown consists of a swing cylinder 14, a central rotating shaft 15, a guide sleeve 16, and a guide shaft 17. The central rotating shaft 15 passes vertically through the square tube seat 12 and is fixedly connected to the longitudinal beam 2. The longitudinal beam 2 passes laterally through the square tube seat 12. The front end of the swing cylinder 14 is hinged to the central support rod 11, and the rear end of the swing cylinder 14 is hinged to the upper end of the central rotating shaft 15. Thus, the extension and retraction of the swing cylinder 14 can drive the central rotating shaft 15 to rotate, and the rotation of the central rotating shaft 15 can drive the longitudinal beam 2 to swing. In order to achieve smooth rotation of the longitudinal beam 2, the front end of the longitudinal beam 2 is provided with a latch 18 that is locked onto the arc plate 13. The arc plate 13 is located on a circle with the central rotating shaft 15 as the center. The latch 18 is composed of two outer extension plates that are locked onto the upper and lower sides of the arc plate 13.

[0028] During the rotation of the longitudinal beam 2 relative to the square tube base 12 driven by the swing cylinder 14, a guide shaft 17 and a guide sleeve 16 are provided between the square tube base 12 and the plow mechanism 3 to achieve the rotation of the plow disc 19 and the plow legs 20. The guide sleeve 16 is horizontally positioned and fixed to the upper end of the plow legs 20 of the plow mechanism 3 near the square tube base 12. The rear end of the guide shaft 17 is hinged to the square tube base 12, and the front end of the guide shaft 17 is inserted into the guide sleeve 16. Thus, during the rotation of the longitudinal beam 2 relative to the square tube base 12 driven by the swing cylinder 14, the guide sleeve 16 limits and guides the guide shaft 17, thereby driving the steering linkage 7 to rotate, which in turn drives all the plow discs 19 to rotate, in order to coordinate with the orientation adjustment of the plow discs 19 during back-and-forth tilling operations.

[0029] like Figure 11The diagram shows a perspective view of the tail wheel mechanism in this invention. The tail wheel mechanism 4 consists of a tail wheel cylinder 24, a vertical shaft 25, a tail wheel sleeve 26, a tail wheel support leg 27, and a tail wheel 28. The vertical shaft 25 is rotatably mounted on the rear end of the longitudinal beam 2 and can rotate on the longitudinal beam 2. The tail wheel sleeve 26 is fixed to the vertical shaft 25. The front end of the tail wheel cylinder 24 is hinged to the longitudinal beam 2, and the rear end of the tail wheel cylinder 24 is hinged to the tail wheel sleeve 26. The tail wheel support leg 27 is L-shaped, with the upper end of the tail wheel support leg 17 fixed to the tail wheel sleeve 26, and the tail wheel 28 located at the lower end of the tail wheel support leg 27. Thus, by extending and retracting the tail wheel cylinder 24, the tail wheel support leg 27 and the tail wheel 28 can be driven to rotate synchronously, changing the position of the tail wheel 28 relative to the longitudinal beam 2 to coordinate with the orientation of the plow disc 19 during back-and-forth tilling operations, thereby providing support for the rear end of the longitudinal beam 2.
