Description

Technical Field

[0001] This utility model relates to the field of wheat pressing roller technology, and in particular to an adjustable wheat pressing roller assembly. Background Technology

[0002] The wheat compaction roller is an important component of a wheat seeder. Its main function is to compact the soil after sowing to increase soil density and firmness, thereby preventing excessive soil moisture loss, protecting soil moisture, maintaining soil temperature, and creating a suitable seedbed environment for seed germination and emergence.

[0003] Traditional wheat press rollers are typically mounted on the rear of the vehicle using a mounting bracket; however, these press rollers have the following drawbacks in use:

[0004] 1. The length of the press roller is fixed and cannot be adjusted according to the soil conditions, which limits its use.

[0005] Therefore, we propose an adjustable wheat pressing roller assembly. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where the length of the pressing roller is fixed and cannot be adjusted according to soil conditions, thus limiting its use. Therefore, this invention proposes an adjustable wheat pressing roller assembly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable wheat compactor roller assembly includes:

[0009] The mounting frame has multiple connection holes at its top, and side plates are fixed on both sides of the mounting frame. A rotating shaft passes through one side of each side plate, and a common connecting shell is fixed between the two rotating shafts. Multiple detachable pressing rollers are sleeved on the outside of the connecting shell.

[0010] Two sliding plates are slidably connected between the inner walls of the two sides of the connecting shell. Multiple tension springs are fixed between the two sliding plates. Multiple trapezoidal blocks are fixed on the side of the two sliding plates that are close to each other, and multiple pairs of first positioning blocks are fixed on the side of the two sliding plates that are far from each other. The first positioning blocks slide through the connecting shell and are used to position the detachable pressing roller.

[0011] An adjustment mechanism is provided on the inner side of the connecting shell and is used to adjust the distance between the two sliding plates.

[0012] In one possible design, the detachable press roller includes two half press rollers, each half press roller having a connecting groove adapted to the connecting shell on one side, and a first positioning groove being formed on the top inner wall and bottom inner wall of the connecting groove, with a first positioning block cooperating with the first positioning groove.

[0013] In one possible design, one of the semi-press rollers has two second positioning blocks integrally formed on one side, and the other semi-press roller has two second positioning grooves on one side, with the second positioning blocks and second positioning grooves cooperating with each other.

[0014] In one possible design, the surface and bottom of the connecting shell are integrally formed with multiple positioning strips, and the top inner wall and bottom inner wall of the connecting groove are each provided with two third positioning grooves, with the positioning strips and the third positioning grooves cooperating with each other.

[0015] In one possible design, the adjustment mechanism includes an adjustment rod and multiple push blocks. The adjustment rod rotatably passes between the inner walls of both sides of the connecting shell, and the multiple push blocks are slidably connected between the inner walls of both sides of the connecting shell. The adjustment rod is threaded through the multiple push blocks, and the push blocks cooperate with the trapezoidal blocks. The two ends of the adjustment rod extend to the inner sides of the two rotating shafts and are fixed with adjustment blocks.

[0016] In one possible design, one end of both shafts is threaded with a protective sleeve.

[0017] In this application, when adjusting the length of the press roller (taking increasing the length as an example), first remove the protective cover, and use a wrench or other suitable tool to rotate the adjusting block. The adjusting block drives the adjusting rod to rotate, and the adjusting rod drives the push block to move, causing the push block to disengage from the trapezoidal block. Under the action of the tension spring, the sliding plate pulls the first positioning block into the connecting shell. Then, take the half press roller to be installed, align it with the positioning strip and the third positioning groove, and put the half press roller on the connecting shell so that the second positioning block and the second positioning groove are engaged. Then, rotate the adjusting block in the opposite direction so that the push block pushes the trapezoidal block, thereby causing the first positioning block and the first positioning groove to be engaged, completing the positioning of the half press roller. Then, put the protective cover back on. When reducing the length, repeat the above operation in the reverse direction.

[0018] Beneficial effects: In this utility model, the adjustable wheat pressing roller assembly, through the setting of multiple structures such as the detachable pressing roller, the first positioning block and the sliding plate, allows people to easily adjust the length of the pressing roller according to the situation, making it more flexible and convenient to use;

[0019] In this utility model, the adjustable wheat pressing roller assembly, through the setting of multiple structures such as the second positioning block, the second positioning groove and the third positioning block, can facilitate the assembly of the detachable pressing roller and ensure the stability after assembly.

[0020] This invention allows for convenient adjustment of the length of the press roller according to the situation, making it more flexible and convenient to use. It also facilitates the assembly of the detachable press roller and ensures the stability of the assembled roller. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figures 1-3 An adjustable wheat press roller assembly includes:

[0027] Mounting frame 1, with multiple connecting holes 2 at the top, side plates 3 fixed on both sides of mounting frame 1, and rotating shafts 4 rotatably passing through one side of each side plate 3, with the same connecting shell 5 fixed between the two rotating shafts 4, and multiple detachable pressing rollers sleeved on the outside of the connecting shell 5, which can be replaced or adjusted according to actual needs.

[0028] Two sliding plates 7 are slidably connected between the inner walls of the two sides of the connecting shell 5. Multiple tension springs 12 are fixed between the two sliding plates 7. Without external force, the tension springs 12 can pull the two sliding plates 7 closer to each other. Multiple trapezoidal blocks 8 are fixed on the side where the two sliding plates 7 are close to each other, and multiple pairs of first positioning blocks 9 are fixed on the side where the two sliding plates 7 are far apart from each other. The first positioning blocks 9 slide through the connecting shell 5. The first positioning blocks 9 are used to position the detachable pressing roller.

[0029] An adjustment mechanism, located inside the connecting shell 5, is used to adjust the distance between the two sliding plates 7. The adjustment mechanism includes an adjustment rod 11 and multiple push blocks 10. The adjustment rod 11 rotatably passes between the inner walls of both sides of the connecting shell 5. The multiple push blocks 10 are slidably connected between the inner walls of both sides of the connecting shell 5. The adjustment rod 11 is threaded through the multiple push blocks 10, which cooperate with the trapezoidal block 8. Both ends of the adjustment rod 11 extend to the inner sides of the two rotating shafts 4 and are fixed with adjustment blocks 14. When the adjustment rod 11 rotates, the push blocks 10 slide along the inner wall of the connecting shell 5 due to the thread. The sliding of the push blocks 10 pushes or pulls the trapezoidal block 8, thereby moving the sliding plates 7 and adjusting the distance between the two sliding plates 7, thus allowing the first positioning block 9 and the first positioning groove 17 to align.

[0030] The detachable press roller includes two half press rollers 15. Each half press roller 15 has a connecting groove 16 on one side that matches the connecting shell 5, so that the half press roller 15 can be sleeved on the outside of the connecting shell 5. The top inner wall and the bottom inner wall of the connecting groove 16 are provided with a first positioning groove 17. The first positioning block 9 cooperates with the first positioning groove 17 to achieve positioning and fixing of the half press roller 15.

[0031] One of the half-pressing rollers 15 has two second positioning blocks 18 integrally formed on one side, and the other half-pressing roller 15 has two second positioning grooves 19 on one side. The second positioning blocks 18 and the second positioning grooves 19 cooperate with each other, making the connection between the two half-pressing rollers 15 more stable and reliable.

[0032] Multiple positioning strips 13 are integrally formed on the surface and bottom of the connecting shell 5. Two third positioning grooves 20 are opened on the top inner wall and bottom inner wall of the connecting groove 16. The positioning strips 13 and the third positioning grooves 20 cooperate to position the semi-pressing roller 15, thereby aligning the first positioning block 9 and the first positioning groove 17, which facilitates the assembly of subsequent structures.

[0033] Example 2: An adjustable wheat pressing roller assembly improved based on Example 1;

[0034] In another aspect of this embodiment, one end of each of the two rotating shafts 4 is threaded with a protective sleeve 6. The protective sleeve 6 can effectively prevent foreign objects from entering the interior of the rotating shaft 4 and causing interference or damage to the adjusting rod 11.

[0035] 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.
