Description

Technical Field

[0001] This utility model relates to the field of deep tillage machinery, and in particular to a device for quickly changing plowshares in deep tillage machinery. Background Technology

[0002] Deep tillage is an important soil cultivation technique in agricultural production. It can effectively break up the plow pan, improve soil structure, enhance water retention capacity, and create favorable conditions for crop growth. As the core working component of the deep tillage machine, the plowshare is subjected to huge friction and impact during operation, and wears out extremely quickly, requiring frequent replacement.

[0003] Existing quick-change plowshare deep-tillage agricultural machinery devices are typically fixed directly by multiple bolts. The replacement operation is cumbersome and time-consuming. Operators must use special tools such as wrenches to tighten or loosen multiple bolts one by one. Moreover, in the harsh environment of the field, the bolts and nuts are easily covered by mud and corroded, making disassembly difficult. Therefore, those skilled in the art have provided a quick-change plowshare deep-tillage agricultural machinery device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick plowshare replacement deep tillage agricultural machinery device. The replacement structure forms a precise installation position on the inclined rod through two rectangular frames. The operator only needs to place the concave block into this position to quickly achieve its initial axial and circumferential positioning on the inclined rod. Then, the concave block is fixed to the inclined rod by a threaded post, achieving quick assembly and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick plowshare replacement deep tillage agricultural machinery device, comprising a device body, the device body being L-shaped, with inclined rods fixedly connected to both ends of the device body, and three replacement structures arranged in a straight line on the outer side of the inclined rods, with three protective structures sleeved on the outer side of the three replacement structures;

[0006] Taking the replacement structure mentioned earlier as an example, the replacement structure includes two rectangular frames. The two rectangular frames are arranged in a straight line at the center of the outer side of the diagonal rod. A concave block is sleeved on the outer side of the diagonal rod between the two rectangular frames. A plowshare is provided on the lower end face of the concave block. A circular hole is provided at the center of one side of the concave block. The circular hole passes through one side of the concave block and leads to the other side of the concave block. A threaded post is threaded inside the circular hole.

[0007] With the above technical solution, two rectangular frames are welded to the outside of the inclined rod. The concave block is fitted onto the inclined rod between the two rectangular frames. Then, the threaded post is screwed into the round hole to fix the concave block. The replacement structure forms a precise installation position on the inclined rod through the two rectangular frames. The operator only needs to put the concave block into this position to quickly achieve its initial axial and circumferential positioning on the inclined rod. Then, the concave block is fixed on the inclined rod by the threaded post, realizing quick assembly and disassembly.

[0008] Furthermore, taking the protective structure at the front as an example, the protective structure includes a protective frame, which is sleeved on the outside of the concave block. A convex groove is provided at the center of the upper end face of the protective frame, and a fixing block is provided at the center of the front end face of the convex groove. The fixing block passes through the front end face of the convex groove and extends to the rear end face of the convex groove. Springs are provided at the center of both the front and rear end faces of the fixing block. Movable blocks are provided at the lower center of the front end face of the spring and the rear end face of the spring. Sliding grooves are provided at the upper center of the rear end face of the concave block and the front end face of the concave block. Sliding blocks are provided at the lower center of the front end face of the moving block and the rear end face of the moving block.

[0009] With the above technical solution, the two moving blocks are manually pinched, and then the protective frame is placed on the outside of the concave block. After releasing the two moving blocks, the two springs reset and push the sliding block into the two sliding grooves to limit the protective frame. The protective structure protects the threaded column and nut through the protective frame, preventing the mud generated during the use of the device from corroding the threaded column and nut and affecting the normal use of the replacement structure. At the same time, it prevents the nut from accidentally falling off during the use of the device, thus improving the safety of the device during use.

[0010] Furthermore, a lifting device is provided at the rear center of the upper end face of the main body of the device;

[0011] Through the above technical solution, and by linking with the tractor's hydraulic suspension system, the driver can easily control the raising and lowering of the deep tillage device from the cab, precisely adjust the tillage depth, and lift the entire device off the ground during road transport, avoiding collisions with the ground, thus protecting components such as the plowshare and ensuring road safety.

[0012] Furthermore, support columns are provided at the center of one side of the main body of the device and the other side of the inclined rod, near the front and rear.

[0013] Through the above technical solution, the support column establishes a solid bridge between the main body of the device and the diagonal bar, which could have formed a flexible connection. It transforms the frame from an open L-shape into a stable triangular truss structure, significantly improving the bending and torsional stiffness of the entire device and preventing structural deformation or swaying during heavy-duty farming.

[0014] Furthermore, a nut is threaded onto one side of the outer center of the threaded column;

[0015] The above technical solution uses nuts to fix the threaded post, preventing it from accidentally falling off.

[0016] Furthermore, a circular groove is provided at the center of one side of the concave block, and the nut is located inside the circular groove;

[0017] The above technical solution uses a circular groove to limit the nut, which facilitates the installation of the protective frame while holding the nut in place, preventing the nut from accidentally falling off.

[0018] Furthermore, the two movable blocks are slidably connected inside the convex groove, and the two sliding blocks are respectively slidably connected inside the two sliding grooves and the convex groove;

[0019] The above technical solution satisfies the sliding requirements of the protective structure by sliding the moving block and the sliding block, thus ensuring the normal use of the protective structure.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the quick-change plowshare deep tillage agricultural machinery device has a replacement structure that forms a precise installation position on the inclined rod through two rectangular frames. The operator only needs to place the concave block into this position to quickly achieve its initial axial and circumferential positioning on the inclined rod. Then, the concave block is fixed on the inclined rod by the threaded column, realizing quick assembly and disassembly.

[0022] 2. In this utility model, the protective structure protects the threaded post and nut with a protective frame, preventing the mud generated during the use of the device from corroding the threaded post and nut and affecting the normal use of the replacement structure. At the same time, it prevents the nut from accidentally falling off during the use of the device, thereby improving the safety of the device during use. Attached Figure Description

[0030] Reference Figure 1-4 An embodiment of this utility model is provided: a quick plowshare replacement deep tillage agricultural machinery device, including a device body 1, the device body 1 is L-shaped, and the two ends of the device body 1 are fixedly connected to diagonal rods 2. Three replacement structures 3 are arranged in a straight line on the outside of the diagonal rods 2, and three protective structures 4 are sleeved on the outside of the three replacement structures 3.

[0031] like Figure 2 and 3 As shown, taking the replacement structure 3 at the front as an example, the replacement structure 3 includes two rectangular frames 301. The two rectangular frames 301 are arranged in a straight line at the front of the center of the outer side of the diagonal rod 2. A concave block 302 is fitted on the outer side of the diagonal rod 2 between the two rectangular frames 301. A plowshare 303 is provided on the lower end face of the concave block 302. A circular hole 304 is provided at the center of one side of the concave block 302. The circular hole 304 passes through one side of the concave block 302 and extends to the other side of the concave block 302. A threaded post 306 is threadedly connected inside the circular hole 304. The rectangular frame 301 is welded to the outside of the inclined rod 2. The concave block 302 is fitted onto the inclined rod 2 between the two rectangular frames 301. Then, the threaded post 306 is screwed into the round hole 304 to fix the concave block 302. The replacement structure 3 forms a precise installation position on the inclined rod 2 through the two rectangular frames 301. The operator only needs to put the concave block 302 into this position to quickly achieve its initial axial and circumferential positioning on the inclined rod 2. Then, the concave block 302 is fixed on the inclined rod 2 by the threaded post 306.

[0032] like Figure 2 , 3As shown in Figure 4, taking the front protective structure 4 as an example, the protective structure 4 includes a protective frame 401, which is sleeved on the outside of the concave block 302. A convex groove 402 is provided at the center of the upper end face of the protective frame 401, and a fixing block 403 is provided at the center of the front end face of the convex groove 402. The fixing block 403 passes through the front end face of the convex groove 402 and extends to the rear end face of the convex groove 402. Springs 404 are provided at the centers of both the front and rear end faces of the fixing block 403. Moving blocks 405 are provided at the lower center of the front end face of the spring 404 and the rear end face of the spring 404.

Sliding blocks 407 are provided at the lower center of the front end face of the front moving block 405 and the rear end face of the rear moving block 405. The two moving blocks 405 are manually pinched, and then the protective frame 401 is placed on the outside of the concave block 302. After releasing the two moving blocks 405, the two springs 404 reset and push the sliding blocks 407 into the two sliding grooves 406 to limit the protective frame 401. The protective structure 4 protects the threaded post 306 and the nut 307 through the protective frame 401, so as to prevent the mud generated during the use of the device from corroding the threaded post 306 and the nut 307 and affecting the normal use of the replacement structure 3. At the same time, it prevents the nut from accidentally falling off during the use of the device and improves the safety of the device during use.

[0033] The main body of the device 1 is equipped with a lifting device 5 at the rear center of the upper end face. Through linkage with the hydraulic suspension system of the tractor, the driver can easily control the raising and lowering of the deep tillage device from the cab and accurately adjust the tillage depth.

The circular groove 305 limits the nut 307, so that the nut 307 can be held in place while the protective frame 401 is installed, thus preventing the nut 307 from accidentally falling off.

[0037] Two movable blocks 405 are slidably connected inside the convex groove 402, and two sliding blocks 407 are slidably connected inside the two sliding grooves 406 and the convex groove 402 respectively. By sliding the movable blocks 405 and the sliding blocks 407, the sliding requirements of the protective structure 4 are met, ensuring the normal use of the protective structure 4.

[0038] Working principle: Before use, two rectangular frames 301 are welded to the outside of the inclined rod 2. The concave block 302 is fitted onto the inclined rod 2 between the two rectangular frames 301. Then, the threaded post 306 is screwed into the round hole 304 to fix the concave block 302. The replacement structure 3 forms a precise installation position on the inclined rod 2 through the two rectangular frames 301. The operator only needs to place the concave block 302 into this position to quickly achieve its initial axial and circumferential positioning on the inclined rod 2. Then, the concave block 302 is fixed to the inclined rod 2 by the threaded post 306, achieving quick assembly and disassembly. Finally, the threaded post is fixed by the nut 307. 306 is fixed to prevent the threaded post 306 from accidentally falling off. Then, the two moving blocks 405 are manually pinched, and the protective frame 401 is placed on the outside of the concave block 302. Then, the two moving blocks 405 are released, and the two springs 404 are reset to push the sliding block 407 into the two sliding grooves 406 to limit the protective frame 401. The protective structure 4 protects the threaded post 306 and the nut 307 through the protective frame 401, so as to prevent the mud generated during the use of the device from corroding the threaded post 306 and the nut 307 and affecting the normal use of the replacement structure 3. At the same time, it prevents the nut from accidentally falling off during the use of the device, thus improving the safety of the device during use.
