Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a grinding plate mechanism for leveling land and a land preparation machine. Background Art

[0002] Land preparation machine is a highly efficient agricultural machine used to prepare the field before sowing. It uses a series of tools such as rotary tiller, harrow, plowshare, etc. to turn the soil, break up soil clods and level the land, so that the soil reaches a state suitable for planting. Dry sowing and wet sowing refers to sowing on dry land without immediate irrigation. The seeds absorb moisture from the soil and begin to germinate. After the crops grow out, appropriate irrigation is used to ensure the water supply required for normal growth of the crops. This can save water resources and ensure the growth and development of crops.

[0003] In recent years, Xinjiang has been actively promoting dry seeding and wet-out technology, which generally controls the amount of irrigation water by laying drip irrigation tape on the land. The higher the flatness of the land, the more stable the drip irrigation tape is when it is laid, and the easier it is to control the uniformity. During operation, water is easier to penetrate into the plant root area and less likely to accumulate water, ensuring the irrigation effect. However, after the existing land preparation machine is finished, the land surface is grooved, the land is relatively fluffy, and the flatness cannot achieve the effect of good paving of drip irrigation tape.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a land leveling grinding plate mechanism and a land preparation machine which can further improve the flatness of the land and enable the land to meet the requirements for good paving of drip irrigation tapes.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a grinding plate mechanism for leveling land, including a mounting frame and a grinding plate, the mounting frame including a traction seat and a ground pressing frame, the traction seat is arranged at the front end of the ground pressing frame, the traction seat is used for external ground leveling equipment, the grinding plate is installed at the bottom of the ground pressing frame, and the cross-section of the grinding plate is an arc shape convex toward the front and lower side; as the traction seat pulls the ground pressing frame forward, the grinding plate presses over the land surface and smoothes it.

[0007] Based on the above, the mounting frame further includes a pressure spring, the front end of the ground pressing frame is hinged on the traction seat, and the two ends of the pressure spring are respectively hinged on the traction seat and the ground pressing frame to apply pressure to the ground pressing frame.

[0008] Based on the above, the ground pressing frame includes two L-shaped connecting rods arranged at intervals, one end of the L-shaped connecting rod is connected to the traction seat, and the other end is connected to the grinding plate, and a diagonal brace is arranged on the inner corner side of the L-shaped connecting rod.

[0009] Based on the above, a lug plate is provided on the back of the grinding plate, the lug plate is hingedly connected to the bottom of the ground pressing frame, and an angle adjustment mechanism for adjusting the pitch of the grinding plate is also provided between the lug plate and the ground pressing frame.

[0010] Based on the above, the angle adjustment mechanism includes a locking bolt, a fixed threaded hole opened at the bottom of the ground pressing machine frame and a plurality of adjustment holes opened on the ear plate. By rotating the ear plate, the plurality of adjustment holes are aligned with the fixed threaded hole in turn, and then the locking bolt is used to lock them.

[0011] The utility model also provides a land leveling machine, the rear end of which is equipped with the above-mentioned grinding plate mechanism for leveling the land.

[0012] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0013] (1) The traction seat is connected to the rear end of the land leveling machine, and the land pressing frame presses the grinding plate on the land surface. The land leveling machine levels the land in front and drags the land pressing frame forward. The grinding plate passes through the land surface and smoothes the leveled land.

[0014] (2) The arrangement of the two L-shaped connecting rods and the diagonal braces reduces the deadweight of the ground pressing frame and reduces the dragging resistance while ensuring the connection strength. By arranging the pressure spring, downward pressure is applied to the ground pressing frame to ensure that the grinding plate can smooth the ground.

[0015] (3) By providing the angle adjustment mechanism, it is convenient for workers to adjust the pitch angle of the grinding plate, thereby ensuring a good actual leveling effect at the work site. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the utility model is further described in detail below through specific implementation methods. Example 1

[0022] like Figure 1 and Figure 2 As shown, a grinding plate mechanism for land smoothing includes a mounting frame and a grinding plate 1, wherein the mounting frame includes a traction seat 2 and a ground pressing frame 3, wherein the traction seat 2 is arranged at the front end of the ground pressing frame 3, the traction seat 2 is used for externally connecting a land leveling device to pull the ground pressing frame 3 forward, and the grinding plate 1 is installed at the bottom of the ground pressing frame 3, wherein the cross section of the grinding plate 1 is in the shape of an arc convex toward the front and downward, and as the traction seat 2 pulls the ground pressing frame 3 forward, the grinding plate 1 presses over the land surface and smoothes it.

[0023] During specific use, the traction seat 2 is connected to the rear end of the land leveling machine, and the land pressing frame 3 presses the grinding plate 1 on the land surface. The land leveling machine levels the land in front and drags the land pressing frame 3 forward. The grinding plate 1 passes through the land surface and smoothes the leveled land.

[0024] In order to ensure the smoothing effect, the mounting frame also includes a pressure spring 4. The front end of the ground pressing frame 3 is hinged on the traction seat 2. The two ends of the pressure spring 4 are respectively hinged on the traction seat 2 and the ground pressing frame 3 to apply pressure to the ground pressing frame 3. At the same time, in order to reduce the deadweight of the mechanism, the ground pressing frame 3 includes two L-shaped connecting rods 31 arranged at intervals. One end of the L-shaped connecting rod 31 is connected to the traction seat 2 and the other end is connected to the grinding plate 1. The inner corner side of the L-shaped connecting rod 31 is provided with a diagonal brace 32 to ensure the strength of the frame. In other embodiments, the pressure spring 4 may not be provided. By increasing the deadweight of the ground pressing frame 3, the pressure of the grinding plate 1 is increased, but this structure will also increase the drag resistance.

[0025] In order to adapt to different work sites, an ear plate 5 is provided on the back of the grinding plate 1, and the ear plate 5 is hingedly connected to the bottom of the ground pressing frame 3. An angle adjustment mechanism for adjusting the pitch of the grinding plate 1 is also provided between the ear plate 5 and the ground pressing frame 3; the angle adjustment mechanism specifically includes a locking bolt 6, a fixed threaded hole opened at the bottom of the ground pressing frame 3 and a plurality of adjustment holes 7 opened on the ear plate 5. Through the rotation of the ear plate 5, the plurality of adjustment holes 7 are aligned with the fixed threaded hole in turn, and then the locking bolt 6 is used to lock it to achieve angle adjustment, thereby ensuring that the actual leveling effect at the work site is good. Example 2
