[0002] Agricultural machinery adapters are widely used in agricultural production operations such as land preparation, sowing, weeding, and harvesting. They can be used with different types of tractors to meet the operational needs of various crops and terrains. With the advancement of agricultural modernization and technological progress, agricultural machinery adapters will be applied and developed in more fields. In the future, we can expect to see more intelligent and efficient agricultural machinery adapter products, bringing greater convenience and benefits to agricultural production; therefore, there is a need for such adapters.

[0003] In existing technology, agricultural machinery adapter frames generally include a frame and connecting parts. Workers use tools to connect agricultural machinery equipment with several sets of bolts through the connecting parts for subsequent agricultural machinery operations.

[0004] However, the width and length of the frame are fixed when the above-mentioned device is in use, which makes it inconvenient to connect to different models of equipment and its practicality is poor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an agricultural machinery adapter. Its advantages include improved practicality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An agricultural machinery adapter frame includes a first adapter frame for connecting a tractor and two second adapter frames for connecting agricultural machinery. A connecting mechanism is provided on one side of the first adapter frame, and a disassembly mechanism is provided on one side of each of the second adapter frames.

[0008] The connecting mechanism includes connecting blocks that correspond one-to-one with the second adapter frame. A connecting groove is provided on one side of the first adapter frame. The inner wall of the connecting groove and the connecting block form a sliding fit. A double-threaded rod is rotatably connected to one end of the inner wall of the connecting groove through a bearing. The double-threaded rod and the connecting block are connected by threads. The two connecting blocks move in opposite directions, which can improve the practicality.

[0009] The extension shaft of the double-ended threaded rod is fixedly connected to a rotating disk. One end of the rotating disk has several rotating ports, which allow workers to easily rotate the rotating disk. The rotating disk also facilitates the movement of the connecting block.

[0010] A worm gear is fixedly connected to the surface of the extended shaft of the double-ended threaded rod. A connecting frame is provided above the worm gear. A worm is rotatably connected to the inner wall of the connecting frame through a bearing. The worm meshes with the worm gear. The worm gear can be used to fix the double-ended threaded rod.

[0011] The outer wall of one end of the first adapter frame is provided with a T-shaped positioning groove, and a T-shaped positioning block is slidably connected to the inner wall of the positioning groove. The positioning block is fixed to the connecting frame, and the positioning block can facilitate the adjustment of the position of the connecting block.

[0012] A positioning spring is fixedly connected to the top of the positioning block. The positioning spring is fixed to the top inner wall of the positioning groove. The positioning spring is designed to prevent the worm gear from rotating.

[0013] A limiting sleeve is fixedly connected to the surface of the worm gear. The limiting sleeve is made of rubber and contacts the connecting frame. The limiting sleeve can fix the position of the connecting block.

[0014] The disassembly mechanism includes a disassembly rod that is fixedly connected to one side of the second adapter frame. A threaded groove is provided on one side of the connecting block. The inner wall of the threaded groove is connected to the disassembly rod by a thread. The disassembly rod facilitates the replacement of the second adapter frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This agricultural machinery adapter frame is operated by rotating a rotating disc. The rotation of the disc causes the double-threaded rod to rotate, and the rotation of the double-threaded rod causes the connecting block to slide in the inner wall of the connecting groove. The distance between the two second adapter frames can be adjusted, thus improving practicality.

[0017] 2. This agricultural machinery adapter frame allows for the separation of the disassembly rod from the threaded groove at the connector of the second adapter frame that requires a different design, enabling the replacement of the second adapter frame. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0025] Example 1

[0026] Reference Figure 1-4 An agricultural machinery adapter frame includes a first adapter frame 1 for connecting a tractor and two second adapter frames 2 for connecting agricultural machinery. A connecting mechanism is provided on one side of the first adapter frame 1, and a disassembly mechanism is provided on one side of the second adapter frame 2.

[0027] The connecting mechanism includes connecting blocks 3 that correspond one-to-one with the second adapter frame 2. A connecting groove 4 is provided on one side of the first adapter frame 1. The inner wall of the connecting groove 4 and the connecting block 3 form a sliding fit. A double-threaded rod 5 is rotatably connected to one end of the inner wall of the connecting groove 4 through a bearing. The double-threaded rod 5 and the connecting block 3 are connected by threads. The two connecting blocks 3 move in opposite directions.

[0028] The extension shaft of the double-ended threaded rod 5 is fixedly connected to a rotating disk 6. One end of the rotating disk 6 is provided with several rotating ports 7. The rotating ports 7 allow the operator to easily rotate the rotating disk 6. The operator can easily hold the rotating ports 7 to rotate the rotating disk 6, which facilitates the rotation of the double-ended threaded rod 5 and thus facilitates the movement of the connecting block 3.

[0029] A worm gear 8 is fixedly connected to the extended shaft surface of the double-threaded rod 5. A connecting frame 9 is provided above the worm gear 8. A worm 10 is rotatably connected to the inner wall of the connecting frame 9 through a bearing. The worm 10 meshes with the worm gear 8. When the worm gear 8 contacts the worm 10, it can prevent the rotating disk 6 from rotating and can fix the double-threaded rod 5.

[0030] The outer wall of one end of the first adapter frame 1 is provided with a T-shaped positioning groove 11. The inner wall of the positioning groove 11 is slidably connected to a T-shaped positioning block 12. The positioning block 12 is fixed to the connecting frame 9. The positioning block 12 can slide in the inner wall of the positioning groove 11, which allows the position of the worm gear 10 to be adjusted, the rotating disk 6 to be rotated, and the position of the connecting block 3 to be adjusted.

[0031] The top of the positioning block 12 is fixedly connected to the positioning spring 13, which is fixed to the top inner wall of the positioning groove 11. The positioning spring 13 can apply pressure to the positioning block 12, so that the worm 10 and the worm wheel 8 can be in close contact, thus preventing the worm wheel 8 from rotating.

[0032] The agricultural machinery adapter frame provided by this utility model is used by connecting and fixing the first adapter frame 1 to the drive component of the agricultural machinery, such as a tractor or vehicle. The positions of the two second adapter frames 2 are adjusted according to the installation position of the matching agricultural machinery operation equipment. Pulling the connecting frame 9 separates the worm gear 10 from the worm wheel 8. At this time, the positioning block 12 slides in the inner wall of the positioning groove 11, and the rotating disk 6 is rotated. The rotation of the rotating disk 6 can cause the double-headed threaded rod 5 to rotate. The rotation of the double-headed threaded rod 5 can cause the connecting block 3 to slide in the inner wall of the connecting groove 4, and the distance between the two second adapter frames 2 can be adjusted. Therefore, the practicality can be improved.

[0033] Example 2

[0034] Based on Embodiment 1, this embodiment includes: a limiting sleeve 14 fixedly connected to the surface of the worm gear 10. The limiting sleeve 14 is made of rubber and contacts the connecting frame 9. The limiting sleeve 14 can increase the rotational friction of the worm gear 10, which can further limit the worm gear 10 and prevent the worm wheel 8 from rotating due to the rotation of the worm gear 10. This can fix the position of the connecting block 3. The disassembly mechanism includes a disassembly rod 16 fixedly connected to one side of the second adapter frame 2. A threaded groove 15 is opened on one side of the connecting block 3. The inner wall of the threaded groove 15 is threadedly connected to the disassembly rod 16. The disassembly rod 16 can rotate in the inner wall of the threaded groove 15, which can facilitate the replacement of the second adapter frame 2.

[0035] The technical solution provided in this embodiment is as follows: by rotating the disassembly rod 16, different connectors of the second adapter 2 can be used, which can separate the disassembly rod 16 from the threaded groove 15. At this time, the second adapter 2 can be replaced. If the size of the second adapter 2 is suitable, the disassembly rod 16 can be rotated in the threaded groove 15 to adjust the length of the second adapter 2. At this time, the distance between the agricultural machinery and the drive component can be adjusted.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
