Description

Technical Field

[0001] This utility model relates to the technical field of traction devices for agricultural machinery, and in particular to a traction vehicle device for agricultural machinery manufacturing. Background Technology

[0002] The tractor unit in agricultural machinery manufacturing is a key component for achieving collaborative agricultural operations. In modern agricultural production, it plays a crucial role in connecting various agricultural implements such as tractors, and its performance directly affects agricultural production efficiency and operational safety. However, current technology has significant shortcomings.

[0003] Currently, most agricultural machinery tractors on the market use a plug-in rod structure for connection. In actual field operations, due to the complex and varied terrain and frequent road bumps, this connection method may slip out due to vibration, leading to connection failure. Once the connection breaks, it not only interrupts ongoing agricultural work and delays planting time, but the impact of the sudden breakage may also damage the machinery, increasing maintenance costs. Although some tractors are equipped with limiting structures to enhance connection stability, these designs often lack ergonomic considerations. In actual operation, the disassembly and assembly of these limiting structures are cumbersome, increasing operational difficulty and significantly reducing work efficiency.

[0004] Therefore, how to design a tractor unit that can maintain a stable connection on bumpy roads and is easy to assemble and disassemble has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Several hooks are provided along the width direction of the side walls of the tractor, and the hooks are used to connect with the fixing holes of the tarpaulin rolls. The driving component is connected to any one of the rotating rods.

[0015] Furthermore, the driving component is a handwheel, which is fixedly connected to any one of the rotating rods. Two overlapping rods are evenly distributed on the opposite side wall of the tractor vehicle near the upper end. The two overlapping rods are symmetrically arranged on both sides of the rotating rod. The overlapping rods and the movable rod are selectively overlapped. The side wall of the movable rod is provided with a limiting component. The opposite side wall of the tractor vehicle is provided with two limiting holes, and the two limiting holes are respectively located on both sides of the rotating rod.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides a tractor device for agricultural machinery manufacturing, including a movable tractor 1 with a connecting plate 2 at its lower end; one end of a traction frame 3 is hinged to the connecting plate 2, while the other end is slidably and rotatably connected to a connecting rod 4. The slidable and rotatable connection between the traction frame 3 and the connecting rod 4 is existing technology and will not be described in detail here; the mounting plate 5 is a connection structure for agricultural machinery such as tractors (not shown in the figure), and the mounting holes of the connecting rod 4 and the mounting plate 5 are detachably connected by a fixing pin 6. The fixing pin 6 has a through hole in the horizontal direction, passing through one end of the connecting rod 4 and the mounting plate 5; limiting... Pin 7 is detachably inserted into the through hole. A first connecting hole 8 is provided at one end of the limiting pin 7, and a second connecting hole 9 is provided at the other end. The fixing ring 10 is rotatably and slidably arranged in the first connecting hole 8. One end of the fixing ring 10 slides through the second connecting hole 9, and the two ends of the fixing ring 10 overlap along the circumferential direction. The shape of the fixing ring 10 can be referenced from a key ring. Its function is to prevent the limiting pin 7 from accidentally falling off. A leveling support is provided between the traction frame 3 and the connecting plate 2. The leveling support can keep the traction frame 3 in a horizontal state in its natural state, which facilitates the subsequent docking of the connecting rod 4 and the mounting plate 5.

[0032] Reference Figure 2One end of the traction frame 3 and the connecting plate 2 are hinged by a hinge 11. The cross-section of the hinge 11 is U-shaped. One end of the traction frame 3 is located in the concave surface of the hinge 11. This design allows the traction frame 3 to rotate up and down around the hinge point. The leveling support is the first spring 13. The lower end of the traction frame 3 and the lower end of the hinge 11 are both vertically provided with fixing plates 12. The first spring 13 is fixedly installed between the two fixing plates 12.

[0033] A reinforcing plate 14 is provided between the hinge 11 and the connecting plate 2.

[0034] Reference Figure 1 and Figure 3 Rotating rods 15 are rotatably connected to the opposite side walls of the tractor 1. The rotating rods 15 are vertically fixed to the movable rods 16. A support rod 17 is arranged between the two movable rods 16. The support rod 17 is used to install the tarpaulin roll 18. Several hooks 19 are arranged along the width direction on the side wall of the tractor 1. The hooks 19 are used to connect with the fixing holes (not shown in the figure) of the tarpaulin roll 18. The driving component is connected to any one of the rotating rods 15.

[0035] The driving component is a handwheel 20, which is fixedly connected to any one of the rotating rods 15. By rotating the handwheel 20, the rotating rod 15 can be rotated, thereby realizing the operation of raising and lowering the tarpaulin. Two overlapping rods 21 are evenly distributed on the opposite side wall of the tractor 1 near the upper end. The two overlapping rods 21 are symmetrically arranged on both sides of the rotating rod 15. The two overlapping rods 21 can limit the starting position of the rotating rod 15, preventing the rotating rod 15 from rotating downwards due to its own weight and the influence of the tarpaulin roll 18. The overlapping rod 21 and the movable rod 16 are selectively overlapped. The side wall of the movable rod 16 is provided with a limiting component 22. The opposite side wall of the tractor 1 is provided with two limiting holes 23, and the two limiting holes 23 are located on both sides of the rotating rod 15. The limiting component 22 and the limiting hole 23 can be detachably inserted. The overlapping rod 21 and the limiting component 22 can doubly limit the starting position of the rotating rod 15. Under the action of the overlapping rod 21 and the limiting component 22, the rotating rod 15 can be prevented from rotating due to bumps.

[0036] Reference Figure 6The limiting component 22 includes a mounting frame 24, a pin 25, a limiting protrusion 26, a second spring 27, and a snap-fit ​​bracket 28. The side wall of the movable rod 16 is provided with the mounting frame 24. One end of the pin 25 slides and rotates vertically through the mounting frame 24 and is detachably inserted into the limiting hole 23. The other end of the pin 25 extends out of the upper end of the mounting frame 24. The side wall of the pin 25 is provided with two limiting protrusions 26. The side wall of the limiting protrusions 26 selectively abuts against the inner bottom of the mounting frame 24. The second spring 27 is sleeved on the periphery of the pin 25 and is located between the top of the mounting frame 24 and the limiting protrusions 26. The inner side wall of the mounting frame 24 is provided with a snap-fit ​​bracket 28. The snap-fit ​​bracket 28 is provided with a snap-fit ​​groove 29. The snap-fit ​​groove 29 selectively snaps into any one of the limiting protrusions 26.

[0037] The longitudinal section of the mounting frame 24 is U-shaped, the longitudinal section of the pin 25 is L-shaped, and the edge of one end of the pin 25 is wedge-shaped.

[0038] Reference Figure 1 The lower end of the tractor 1 is equipped with four movable wheels 30, which provide the tractor 1 with mobility and enable it to move around the work site.

[0039] The working principle of this utility model is as follows: When it is necessary to connect other agricultural machinery, the mounting hole of the connecting rod 4 and the mounting hole of the mounting plate 5 are passed through the fixing pin 6, and then the limiting pin 7 is inserted into the through hole of the fixing pin 6. At this time, the fixing ring 10 is rotated around the first connecting hole 8, so that the hollow part in the middle of the fixing ring 10 passes through the lower end of the fixing pin 6. Then, the overlapping ends of the fixing ring 10 are pried open, and the fixing ring 10 is rotated horizontally so that one end slides through the second connecting hole 9, thereby completing the limitation of the fixing pin 6.

[0040] When transporting goods and needing to be covered with a tarpaulin, connect the fixing hole of the tarpaulin roll 18 to the hook 19 on the side wall of the tractor 1. At this time, the worker pulls the pin 25 upward to release the connection between the pin 25 and the limiting hole 23. Rotate the pin 25 to make the limiting protrusion 26 engage in the locking groove 29. Then the worker rotates the handwheel 20, which drives the rotating rod 15 to rotate, thereby driving the connected movable rod 16 and support rod 17 to rotate, so that the tarpaulin roll 18 gradually unfolds and the tarpaulin is laid.

[0041] After the rotating rod 15 is rotated to the appropriate position, the movable rod 16 first engages with the overlapping rod 21, achieving initial positioning of the rotating rod 15. Next, the pin 25 is pulled up, and the limiting protrusion 26 disengages from the locking groove 29 of the locking bracket 28. Then, the pin 25 is rotated, causing the limiting protrusion 26 to be misaligned with the locking groove 29. Under the elastic force of the second spring 27, the pin 25 is inserted into the limiting hole 23. At this time, the limiting protrusion 26 abuts against the inner bottom of the mounting frame 24. Through the above operations, further positioning of the rotating rod 15 is achieved. This double-positioning structure prevents the rotating rod 15 from rotating due to bumps.
