Description

Technical Field

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

[0002] Tractor-mounted agricultural machinery can complete tasks such as ditching, digging, conveying and separating, removing stems and vines, and loading into vehicles in one go. It is an agricultural machine that is attached to the back of a tractor by a tractor and pulled by the tractor to complete various tasks.

[0003] In the prior art, patent application CN211592130U includes a tractor body and an agricultural machinery body mounted on top of the tractor body. A piston cylinder is fixedly connected to the upper end of the tractor body, and a hydraulic box is sealed and fixedly connected to one side of the piston cylinder. A connection hole communicating with the hydraulic box is opened on one side of the piston cylinder. A large hydraulic piston is sealed and slidably connected inside the hydraulic box. A drive device is located on the side of the large hydraulic piston away from the connection hole. Two small hydraulic pistons are symmetrically sealed and slidably connected inside the piston cylinder. In this invention, when the electric push rod pushes the large hydraulic piston, the two small hydraulic pistons, under hydraulic pressure, drive pins to move in opposite directions, thereby inserting the pins into pin holes on the corresponding support plates, completing the connection between the tractor body and the agricultural machinery body. The structure is simple, the operation is convenient, and it facilitates the alignment and connection of the two.

[0004] However, due to differences in functional design, different types of agricultural machinery often have different traction interface heights. The docking height of existing traction devices is mostly fixed and cannot be flexibly adjusted according to the interface height of agricultural machinery. This defect means that when docking agricultural machinery of different heights, workers need to use additional tools such as wooden blocks and jacks to adjust the height of the machinery, or repeatedly move the relative position of the tractor and the agricultural machinery. This not only increases the number of operating steps and labor intensity, but may also lead to unstable docking due to improper height matching, affecting operational safety and traction efficiency.

[0005] Therefore, it is necessary to provide a traction device for agricultural machinery to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a traction device for agricultural machinery, which solves the problems of existing traction devices having a fixed docking height, which cannot be adapted to the interface height of different agricultural machinery, resulting in cumbersome docking operations, high labor intensity, and poor docking stability.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a traction device for agricultural machinery provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure. Figure 3 for Figure 1 The diagram shows the structure of the limiting component.

[0029] A traction device for agricultural machinery includes: mounting component 1;

[0030] Fixing plate 2, the fixing plate 2 being disposed on the back of the mounting assembly 1;

[0031] Sliding plate 3, the sliding plate 3 being disposed on the inner side of the mounting assembly 1;

[0032] Limiting component 4, which is disposed on the front side of the sliding plate 3;

[0033] The bracket 5 is disposed on the front of the limiting component 4, and a positioning pin 6 is inserted into the inside of the bracket 5.

[0034] The mounting assembly 1 includes a mounting bracket 11, which is fixedly mounted on the front side of the fixing plate 2. Sliding grooves 12 are provided on both sides of the mounting bracket 11, and multiple positioning rods 13 are fixedly mounted on both sides of the front side of the mounting bracket 11.

[0035] The sliding plate 3 is slidably connected to the inner side of the groove 12.

[0036] The limiting component 4 includes a support frame 41, which is fixedly installed on the front of the sliding plate 3. The support frame 41 has a moving groove 42 on both sides. A sliding rod 43 is fixedly installed on the inner side of the support frame 42. A first spring 44 is sleeved on the outer side of the sliding rod 43. A moving plate 45 is slidably connected to the outer side of the sliding rod 43. A positioning hole 46 is opened at both ends of the moving plate 45. The positioning hole 46 is engaged with the outer side of the positioning rod 13.

[0037] The two ends of the movable plate 45 are slidably connected to the inner sides of the two movable slots 42, and one end of the first spring 44 abuts against the front of the movable plate 45.

[0038] Multiple positioning rods 13 are evenly installed on the front of the mounting frame 11. When in use, they are inserted into the outer side of different positioning rods 13 through positioning holes 46, which can limit the sliding plate 3 at different positions so as to adapt to agricultural machinery of different heights for connection.

[0039] The sliding plate 3 slides on the inner side of the slide groove 12, and can limit the sliding plate 3 during use.

[0040] When in use, the first spring 44 always pushes the moving plate 45 toward one side of the positioning rod 13, so that the positioning hole 46 is stably fitted onto the outer side of the positioning rod 13, increasing the connection stability.

[0041] The working principle of the traction device for agricultural machinery provided by this utility model is as follows:

[0042] Before use, the traction device is fixed to the traction end of the tractor by the fixing plate 2. According to the traction interface height of the agricultural machinery to be connected, the position of the sliding plate 3 is adjusted, and the moving plate 45 of the limiting component 4 is pulled forward. The moving plate 45 slides along the sliding rod 43 and compresses the first spring 44, so that the positioning holes 46 at both ends of the moving plate 45 are disengaged from the positioning rod 13 of the mounting frame 11, and the height lock is released.

[0043] Push the sliding plate 3 up and down. The sliding plate 3 slides along the sliding grooves 12 on both sides of the mounting frame 11, driving the bracket 5 and the positioning pin 6 to rise and fall synchronously until the height of the positioning pin 6 is aligned with the height of the traction interface of the agricultural machinery. Release the moving plate 45, and the first spring 44 resets and pushes the moving plate 45 to slide backward, so that the positioning hole 46 is re-engaged on the outer side of the positioning rod 13 at the corresponding height, completing the height locking of the sliding plate 3 and ensuring the stability of the docking height.

[0044] Then, align the traction interface of the agricultural machinery with the bracket 5, insert the positioning pin 6 through the traction interface and the bracket 5, and realize the mechanical connection between the tractor and the agricultural machinery.

[0045] Compared with related technologies, the traction device for agricultural machinery provided by this utility model has the following beneficial effects:

[0046] The mounting component 1, sliding plate 3, and limiting component 4 work together to achieve the following: During use, pulling forward the moving plate 45 of the limiting component 4 disengages its positioning hole 46 from the positioning rod 13 of the mounting component 1. This allows the sliding plate 3 to slide up and down along the groove 12 of the mounting frame 11, causing the bracket 5 and positioning pin 6 to rise and fall synchronously. After adjusting to the appropriate height, releasing the moving plate 45 causes the first spring 44 to reset, re-engaging the positioning hole 46 with the positioning rod 13 and locking the height. This allows for multi-level height adjustment, adapting to the traction interface heights of most agricultural machinery on the market, improving the device's versatility, meeting the flexible docking needs of traction-type agricultural machinery in different operating scenarios, and balancing ease of operation with docking stability.

[0047] Second Embodiment

[0048] Please refer to the following: Figure 4 Based on the first embodiment of this application, which provides a traction device for agricultural machinery, the second embodiment of this application proposes another traction device for agricultural machinery. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0049] Specifically, the second embodiment of this application provides a different type of traction device for agricultural machinery, wherein the positioning pin 6 is provided with a positioning component 7 inside the traction device for agricultural machinery.

[0050] The positioning component 7 includes a sliding cavity 71, which is located inside the bottom of the positioning pin 6. Limiting grooves 72 are formed at the top and bottom of the inner side of the sliding cavity 71. A second spring 73 is provided on the inner side of the sliding cavity 71. Slider blocks 74 are fixedly installed at both ends of the second spring 73. Limiting blocks 75 are fixedly installed at the top and bottom of the two sliders 74. The limiting blocks 75 are slidably connected to the inner side of the limiting grooves 72.

[0051] The working principle of the traction device for agricultural machinery provided by this utility model is as follows:

[0052] When in use, the bottom of the slider 74 abuts against the top of the bracket 5. Since the bottom of the slider 74 is provided with an inclined surface, the slider 74 will move towards the inner side of the slide cavity 71 until the positioning pin 6 passes through the traction interface of the agricultural machinery and the bracket 5. Then, the second spring 73 resets and pushes the two sliders 74 to extend to both ends of the slide cavity 71. The part of the slider 74 that extends out of the positioning pin 6 is engaged with the bottom of the bracket 5.

[0053] Compared with related technologies, the traction device for agricultural machinery provided by this utility model has the following beneficial effects:

[0054] With the positioning component 7 in place, the slider 74 is locked at the bottom of the bracket 5 during use. This increases the stability of the positioning pin 6 when it is inserted into the bracket 5 and the traction interface, preventing the positioning pin 6 from falling off during subsequent use.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
