Description

Technical Field

[0001] This utility model relates to the field of trenching technology, specifically a contour disc trenching device. Background Technology

[0002] The contour disc ditcher is a key component of agricultural seeding and fertilizing machinery. It is connected to a tractor or other power equipment and driven by the tractor. The engine's rotation is transmitted to a large-diameter disc equipped with blades, which then rotates to cut the soil. It is suitable for planting various crops, such as corn, wheat, soybeans, and cotton, and can be used under different soil conditions and farming methods, including conventional tillage, no-tillage, and reduced tillage.

[0003] However, the existing contouring disc trenchers may have limitations in the adjustment angle and direction of the discs due to the traditional connection method, which is not conducive to multi-dimensional angle and direction adjustment. Furthermore, when contouring the land, two sets of discs are often adjusted simultaneously. When working in hilly areas or on land with unevenness on one side, the disc on one side cannot be adjusted separately according to the higher mound or depression, which will affect the adaptability of the trencher in different working environments.

[0004] Therefore, we propose a contour disc trencher to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a contour-following disc trencher to solve the problems mentioned in the background art. In the use of existing contour-following disc trenchers, the traditional connection method may limit the adjustment angle and direction of the disc, which is not conducive to multi-dimensional angle and direction adjustment. Moreover, when contouring the land, two sets of discs are often adjusted simultaneously. When working in hilly areas or on land with unevenness on one side, the disc on one side cannot be adjusted separately according to the higher mound or depression, which will affect the adaptability of the trencher in different working environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a contour disc trencher, comprising a support frame and an adjustment mechanism. Rotating discs are arranged on both sides of the support frame. The adjustment mechanism, which allows for adjustable trenching angles, is located in the center of the rotating discs. The adjustment mechanism includes a ball joint seat, a ball head, a support rod, a bearing seat, a threaded groove, a turning push rod, and an extrusion plate. A ball head is located in the center of the inner side of the ball joint seat, and a support rod is fixed to the rear end of the ball head. A bearing seat is installed in the center of the support rod. A threaded groove is located in the center of the front end of the ball joint seat, and a turning push rod is installed in the center of the threaded groove. An extrusion plate is rotatably installed at the front end of the turning push rod.

[0007] Preferably, the support rod is rotatably connected to the ball joint seat via a ball head, and the turning push rod is threadedly connected to the ball joint seat via a threaded groove, and the rotating disk is rotatably connected to the support rod via a bearing seat.

[0008] Preferably, a shock-resistant buffer mechanism is installed above the support frame. The buffer mechanism includes a connecting frame and a damping spring arm, and the damping spring arm is installed at the middle of the rear end of the connecting frame.

[0009] Preferably, the buffer mechanism further includes a connector, and the front end of the damping spring arm is fitted with the connector.

[0010] Preferably, the buffer mechanism further includes a connecting frame, which is installed below the connector.

[0011] Preferably, the support frame is rotatably connected to the connector via a connecting rotating frame, and the support frame is elastically connected to the connecting frame via the connecting rotating frame, the connector, and the damping elastic arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the coordination between various parts of the adjustment mechanism, enables two sets of rotating discs to be adjusted independently. Thus, when working in hilly areas or on uneven land, one set of rotating discs can be adjusted independently according to higher mounds or depressions to maintain good contact with the ground and ensure consistency in trenching depth and quality, while the other set of rotating discs maintains normal operating status, making the entire operation process smoother. This allows the trencher to adapt to different land environments and adjust its operation, improving the applicability of the device.

[0014] 2. This utility model allows for adjustment of the tightness of the ball head by adjusting the extrusion plate, as well as the angle adjustment and fixed positioning of the rotating disc. This prevents the rotating disc from being too flexible and affecting the stability of the operation. At the same time, the buffer mechanism allows the support frame to float up and down according to the flatness of the soil surface, enabling the trencher to better adapt to different terrains and buffer the force when colliding with hard rocks.

[0020] 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.

[0021] like Figures 1-4 As shown, a contoured disc trencher includes a support frame 1 and an adjustment mechanism 3. Rotating discs 2 are arranged on both sides of the support frame 1. The adjustment mechanism 3, which allows for adjustable trenching angles, is located in the middle of the rotating discs 2. The adjustment mechanism 3 includes a ball joint seat 301, a ball head 302, a support rod 303, a bearing seat 304, a threaded groove 305, a turning push rod 306, and a pressing plate 307. A ball head 302 is located in the middle of the inner side of the ball joint seat 301, and the support rod 303 is fixed to the rear end of the ball head 302. A bearing seat 304 is installed in the middle of the support rod 303. A threaded groove 305 is located in the middle of the front end of the ball joint seat 301, and a turning push rod 306 is installed in the middle of the threaded groove 305. The pressing plate 307 is rotatably installed at the front end of the turning push rod 306. The support rod 303 is rotatably connected to the ball joint seat 301 via the ball head 302. The rotating discs 2... The bearing seat 304 is rotatably connected to the support rod 303. Through the ball head 302, it can rotate flexibly at multiple angles within the ball joint seat 301. This allows the support rod 303 to drive the rotating disk 2 on it to be adjusted at multiple angles. At the same time, the two sets of rotating disks 2, as well as the corresponding ball heads 302 and ball joint seats 301, are independently set about the support frame 1. This allows the two sets of rotating disks 2 to be adjusted individually. When working in hilly areas or on uneven land, one set of rotating disks 2 can be adjusted individually according to higher mounds or depressions to maintain good contact with the ground and ensure consistency in trenching depth and quality. The other set of rotating disks 2 maintains normal operating status, making the entire operation process smoother. This allows the trencher to adapt to different land environments and adjust its operation, improving the applicability of the device.

[0022] The push rod 306 is threadedly connected to the ball joint seat 301 through the threaded groove 305. By turning the push rod 306, it can rotate forward and backward in the threaded groove 305, thereby moving the pressing plate 307 back and forth in the predetermined groove in the ball joint seat 301. This allows the tightness of the ball head 302 in the ball joint seat 301 to be adjusted by moving the pressing plate 307, so as to facilitate the adjustment of the angle of the rotating disk 2 and the tight fixing position after adjustment, and to prevent the rotating disk 2 from being too flexible and affecting the stability of the operation.

[0023] like Figure 1 and Figure 2 As shown, a shock-resistant buffer mechanism 4 is installed above the support frame 1. The buffer mechanism 4 includes a connecting frame 401 and a damping spring arm 402. The damping spring arm 402 is installed at the middle of the rear end of the connecting frame 401. The buffer mechanism 4 also includes a connector 403. The connector 403 is installed at the front end of the damping spring arm 402. The buffer mechanism 4 also includes a connecting rotating frame 404. The connecting rotating frame 404 is installed below the connector 403. The support frame 1 is rotatably connected to the connector 403 through the connecting rotating frame 404. The support frame 1 is also elastically connected to the connecting frame 401 through the connecting rotating frame 404, the connector 403, and the damping spring arm 402.

[0024] The damping elastic arm 402 is set at its tail end on the equipment support of the trencher. The support frame 1 and the rotating disk 2 below are connected by the connector 403 and the connecting frame 404. When the rotating disk 2 is subjected to force, the elastic extension and contraction capability of the damping elastic arm 402 can be used to make the support frame 1 float up and down according to the flatness of the soil surface, so that the trencher can better adapt to different terrains and buffer the force when colliding with hard rocks.

[0025] Working principle: When using this contour disc trencher, the ball head 302 can first rotate flexibly at multiple angles within the ball joint seat 301, thereby enabling the support rod 303 to drive the rotating disc 2 on it to adjust at multiple angles. Subsequently, the two sets of rotating discs 2, along with the corresponding ball heads 302 and ball joint seats 301, are independently set about the support frame 1. When working in hilly areas or on uneven ground, one set of rotating discs 2 can be adjusted individually according to higher mounds or depressions, while the other set of rotating discs 2 remains normal. In operation, by turning the push rod 306, it can rotate forward and backward in the threaded groove 305, thereby moving the extrusion plate 307 back and forth in the predetermined groove in the ball joint seat 301. Then, by moving the extrusion plate 307, the tightness of the ball head 302 in the ball joint seat 301 is adjusted, thereby adjusting the angle of the rotating disc 2 and fixing it in place after adjustment. Finally, by utilizing the elastic extension and retraction capabilities of the damping spring arm 402, the connector 403 and the connecting frame 404, the support frame 1 can float up and down according to the flatness of the soil surface.
