Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery auxiliary equipment, and in particular relates to a multifunctional adjusting device for rotary tillage soil covering thickness. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete ploughing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, which is convenient for the seed drill to operate and provide a good seed bed for later sowing. The baffle behind the existing rotary tiller is a solid plate, which makes it impossible to throw the soil after rotary tillage to the rear of the rotary tiller for covering, resulting in the inability to achieve rotary tillage and sowing integration. Therefore, a multifunctional rotary tillage and soil covering thickness adjustment device suitable for rotary tillage and sowing integrated facilities is needed. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a multifunctional adjusting device for the thickness of rotary tillage covering soil suitable for a rotary tillage and sowing integrated facility. A plurality of vertical grids are provided on the retaining grid plates so that smaller soil blocks after rotary tillage are thrown through the vertical grids to the rear of the rotary tiller to cover the seed trough, which is conducive to realizing the integration of rotary tillage and sowing, while larger soil blocks are blocked by the retaining grid plates for secondary rotary tillage to ensure the quality of cultivated land.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: a multifunctional adjustment device for rotary tillage soil covering thickness, including a retaining grid plate and an adjustment plate, a plurality of vertical grids are arranged on the retaining grid plate, a first left extension part and a first right extension part are extended forward on the left and right sides of the retaining grid plate, a plurality of vertically spaced first mounting holes are arranged on the first left extension part and the first right extension part, a second left extension part corresponding to the first left extension part and a second right extension part are extended forward on the left and right sides of the adjustment plate, a plurality of second mounting holes corresponding to the first mounting holes are arranged on the second left extension part and the second right extension part, the adjustment plate is sleeved on the outside of the retaining grid plate, and the vertical opening size of the vertical grid is adjusted by adjusting the upper and lower positions of the adjustment plate through at least two mounting screws.

[0005] A shock-absorbing rubber pad is arranged on the inner wall of the adjusting plate.

[0006] The inner wall of the retaining grid plate is provided with a plurality of soil-breaking nails.

[0007] The width of the vertical grid is 3 to 4 cm.

[0008] By adopting the above technical scheme, when the utility model is in use, the soil retaining grid plate of the present application is installed on the rear part of the frame of the rotary tiller, and the adjusting plate is installed on the soil retaining grid plate by installing screws, and the vertical opening size of the vertical grid is set appropriately. The vertical opening size of the vertical grid can be adjusted by changing the upper and lower positions of the adjusting plate through the first threaded hole, the second threaded hole and the installing screws, thereby realizing the adjustment of the soil covering thickness, which is conducive to realizing the integration of rotary tillage and sowing.

[0009] To sum up, the utility model has a simple structure, is convenient and fast, and has high feasibility. It uses an adjustment plate to adjust the vertical opening size of the vertical grille to adjust the thickness of the soil covering, which effectively solves the technical problem that the existing rotary tiller cannot throw the tilled soil to the rear of the rotary tiller for covering, thereby making it impossible to achieve integrated rotary tillage and sowing.

[0014] like Figure 1-Figure 3As shown, the utility model of the multifunctional adjusting device for the thickness of the rotary tillage soil covering comprises a retaining grid plate 3 and an adjusting plate 2, wherein a plurality of vertical grids 17 are arranged on the retaining grid plate 3, and a first left extension part 21 and a first right extension part 22 are arranged on the left and right sides of the retaining grid plate 3, and a plurality of vertically spaced first mounting holes 18 are arranged on the first left extension part 21 and the first right extension part 22, and a second left extension part corresponding to the first left extension part 21 and a second right extension part 5 corresponding to the first right extension part 22 are arranged on the left and right sides of the adjusting plate 2, and a plurality of second mounting holes 6 corresponding to the first mounting holes 18 are arranged on the second left extension part and the second right extension part 5, and the adjusting plate 2 is sleeved on the outside of the retaining grid plate 3, and the vertical opening size of the vertical grid 17 is adjusted by adjusting the upper and lower positions of the adjusting plate 2 through at least two mounting screws 7. A shock-absorbing rubber pad is arranged on the inner wall of the adjusting plate 2. The noise caused by vibration during operation can be prevented; the inner wall of the retaining grid plate 3 is provided with a plurality of soil crushing nails 1, and during the operation of the rotary tiller, the soil hits the soil crushing nails 1, which is conducive to soil crushing. In addition, the width of the vertical grid 17 is 3 to 4 cm, with 3.5 cm being the most preferred. The soil blocks passing through the grid opening are usually less than 3 cm, the soil is soft and suitable for planting, and the rotary tillage soil crushing efficiency and the soil block size suitable for planting requirements are well balanced.
