DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: An adjustable tooth pitch pasture planting soil-turning plow, including a first plowshare 1, a first connecting rod 2 fixedly connected to the upper end of the first plowshare 1, a second plowshare 6 arranged on one side of the first plowshare 1, a second connecting rod 7 fixedly connected to the upper end of the second plowshare 6, a pushing mechanism 3 arranged above the first connecting rod 2, and a swinging mechanism 4 arranged inside the pushing mechanism 3;

[0024] The driving mechanism 3 includes a bearing plate 301 arranged above the first connecting rod 2. On one side of the bearing plate 301 away from the first connecting rod 2, a first sliding plate 302 is provided. The connection mode between the first sliding plate 302 and the bearing plate 301 is a vertical sliding connection. A first guiding hole 303 is formed inside one side of the first sliding plate 302. A first guiding rod 304 is arranged inside the first guiding hole 303. The external structural shape of the first guiding hole 303 is an inclined straight line shape, and the first guiding holes 303 are equidistantly distributed inside the first sliding plate 302. And two groups of first guiding holes 303 are symmetrically arranged about the central axis of the bearing plate 301, so that when the first guiding rod 304 is pushed by the first guiding hole 303, it drives the first guiding rod 304 and the second guiding rod 306 to perform a lateral movement along the track of the second guiding hole 305. The slopes of the equidistantly distributed first guiding holes 303 gradually decrease near the central axis of the first sliding plate 302, and the matching mode between the first guiding hole 303 and the first guiding rod 304 is a clearance fit, so that the first guiding rod 304 can gradually expand when moving outward. A second guiding hole 305 is formed inside the lower part of the bearing plate 301. A second guiding rod 306 is arranged inside the second guiding hole 305. The connection mode between the second guiding rod 306 and the bearing plate 301 is a lateral sliding connection. A threaded rod 307 is connected to the other end inside the first sliding plate 302 in a threaded manner. The connection mode between the second guiding rod 306 and the first connecting rod 2 is a fixed connection. The external structural shape of the second guiding rod 306 is a cuboid, and the connection mode between the second guiding rod 306 and the first guiding rod 304 is a fixed connection. And the connection mode between the second guiding rod 306 and the second connecting rod 7 is a vertical sliding connection, so that the second guiding rod 306 will not rotate when moving inside the second guiding hole 305.

[0025] At the other end of the first sliding plate 302 near the inside of the bearing plate 301, a first guiding groove 5 is provided. The swing mechanism 4 includes a third guiding rod 401 arranged inside the first guiding groove 5. The external structure of the first guiding groove 5 is wavy, and the matching mode between the first guiding groove 5 and the third guiding rod 401 is clearance fit, so that when the first guiding groove 5 moves up and down, it can drive the third guiding rod 401 to swing left and right. Inside the bearing plate 301 near one end of the threaded rod 307, a third guiding hole 402 is provided. Inside the third guiding hole 402, a fourth guiding rod 403 is provided. The external structural shape of the third guiding hole 402 is a horizontal straight line, and the upper and lower inner surfaces of the third guiding hole 402 are in contact with the upper and lower outer surfaces of the fourth guiding rod 403, so that the fourth guiding rod 403 can move horizontally along the track of the third guiding hole 402. One end of the fourth guiding rod 403 away from the first sliding plate 302 is fixedly connected to a second sliding plate 404. Inside the second sliding plate 404, a second guiding groove 405 is provided. Inside the second guiding groove 405, a fifth guiding rod 406 is provided. One end of the fifth guiding rod 406 close to the first connecting rod 2 is fixedly connected to a slider 407. Inside the upper end of the second connecting rod 7, a chute 408 is provided. The slider 407 is nested inside the chute 408. The external structural shape of the second guiding groove 405 is an inclined straight line, and the matching mode between the second guiding groove 405 and the fifth guiding rod 406 is clearance fit, so that when the second guiding groove 405 moves horizontally, it can drive the fifth guiding rod 406 and the slider 407 to move up and down.

[0026] When adjustment is needed, rotate the threaded rod 307 to drive the first sliding plate 302 to move up and down, so that the first guiding holes 303 arranged inside the first sliding plate 302 move up and down, and push the first guiding rod 304 and the second guiding rod 306 arranged inside the first guiding holes 303 to move horizontally along the second guiding hole 305, driving the second plowshare 6 and the first plowshare 1 to move horizontally. Because the external structural shape of the first guiding holes 303 is an inclined straight line, and the slope of the equally spaced first guiding holes 303 gradually decreases near the central axis of the first sliding plate 302, the first guiding rod 304 and the second guiding rod 306 in each group will expand equally spaced. Since multiple groups can be set, the usage range is wider.

[0027] When the first sliding plate 302 moves up and down, it can drive the first guiding groove 5 to move up and down, drive the third guiding rod 401, the fourth guiding rod 403 and the second sliding plate 404 to move left and right, drive the second guiding groove 405 to move left and right, so that the fifth guiding rod 406 and the slider 407 move up and down, and make the corresponding second connecting rod 7 and the second plowshare 6 move up and down, and the spacing of the plowshares can be further changed to improve the usage range.

[0028] When the plowshare moves horizontally, part of the plowshare moves up and down, making it easier for the soil and debris adhering to the plowshare to fall off, making it more labor-saving to move the plowshare and reducing the obstruction.

[0029] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
