Description

Technical Field

[0001] The utility model relates to the field of a deep tillage shovel, in particular to a deep tillage shovel and a frame thereof. Background Art

[0002] At present, there is a hard, closed plow bottom layer between the tillage layer and the subsoil layer of farmland in my country, which affects the transfer of matter and energy, thus affecting the development of plants. The purpose of deep tillage is to break this solid plow bottom layer, thereby improving the soil tillage layer structure, optimizing soil composition, increasing soil water storage capacity, and increasing crop yields. During deep tillage, because it is necessary to break the hard plow bottom layer formed over the years, and its working depth is also greater than the traditional tillage depth, its tillage resistance is very large. Among them, the deep tillage shovel is the main working part of the deep tillage machine, and its structural shape has a great influence on the tillage resistance;

[0003] The prior art subsoiler can only be remade after being damaged but cannot be repaired, and has no anti-damage protection mechanism. The utility model solves the above problems. Utility Model Content

[0004] The utility model provides a deep tillage shovel and a frame thereof to solve the technical problems that the deep tillage shovel in the prior art can only be remanufactured but cannot be repaired after being damaged and has no anti-damage protection mechanism.

[0005] A deep tillage shovel and a frame thereof, comprising a shovel handle, a shovel hook connected to the lower end of the shovel handle, a notch provided at the lower part of the shovel hook, a shovel tip connected in the notch, and a lower surface of the shovel tip and a lower surface of the shovel hook located on the same curved surface.

[0006] Furthermore, the width of the shovel tip is not greater than twice the thickness of the shovel handle, and the overlapping length of the shovel tip and the notch is not less than 2 / 3 of the length of the shovel tip.

[0007] Furthermore, the upper end of the shovel handle is connected to the frame through a fastening bolt and a protective bolt, and the hardness of the protective bolt stud is less than the hardness of the shovel handle material.

[0008] Furthermore, a shovel handle is connected to one end and the other end of the frame, and a curved frame is bent at the tail between the one end and the other end of the frame.

[0009] Furthermore, the frame one is connected to the frame two by fastening bolts, and a bent frame is bent at the tail between the head end and the end end of the frame two. The shovel handle at the end of the frame one is fastened to the frame one and the frame two by the fastening bolts of the long handle and the protective bolts of the long handle. The fastening bolts of the long handle and the protective bolts of the long handle are both connected with limiting rings, and the distance from the limiting ring to the inner surface of the frame one is equal to the width of the shovel handle.

[0010] Furthermore, a reinforcing plate is connected between the frame 1 and the frame 2, and the fastening bolts pass through the frame 1, the frame 2 and the reinforcing plate to fasten them.

[0011] Beneficial effects of the utility model:

[0012] 1. When the shovel tip encounters an obstacle, the shovel hook will be damaged first due to the separate design of the shovel tip and the shovel hook, which will not affect the shovel handle and the shovel hook. When repairing, just weld a new shovel tip;

[0013] 2. When the deep loosening shovel encounters an obstacle, the protective bolt breaks, and the deep loosening shovel rotates around the fastening bolt to prevent the deep loosening shovel from breaking;

[0014] 3. The shovel handle can be installed on both sides of the frame, and the installation position can be adjusted according to the ridge distance.

[0015] 4. The curved frame and the frame are integrally formed, the structure is more solid and not easy to break. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] When the shovel tip 3 encounters an obstacle, the shovel hook 2 is damaged first due to the separate design of the shovel tip 3 and the shovel hook 2, and the shovel handle 1 and the shovel hook 2 will not be affected. A new shovel tip 3 can be welded during repair.

[0025] The width of the shovel tip 3 is not greater than twice the thickness of the shovel handle 1, and the overlapping length of the shovel tip 3 and the notch is not less than 2 / 3 of the length of the shovel tip 3;

[0026] The smaller shovel tip 3 has less resistance to entering the soil and can shovel deeper into the ground.

[0027] The upper end of the shovel handle 1 is connected to the frame 4 through a fastening bolt 5 and a protective bolt 6, and the hardness of the stud of the protective bolt 6 is less than the hardness of the material of the shovel handle 1;

[0028] When the deep loosening shovel encounters an obstacle, the protective bolt 6 breaks, and the deep loosening shovel rotates around the fastening bolt 5 to prevent the deep loosening shovel from breaking.

[0029] The front and rear ends of the frame 1 are both connected with a shovel handle 1, and a curved frame 7 is bent at the tail between the front and rear ends of the frame 1;

[0030] The curved frame 7 is integrally formed with the frame 1 4, so the structure is more solid and not easy to break.

[0031] The frame 1 4 is connected to the frame 2 8 by a fastening bolt 5, and a curved frame 7 is bent at the tail between the head end and the end end of the frame 2 8. The shovel handle 1 at the end of the frame 1 4 is fastened to the frame 1 4 and the frame 2 8 by a long handle fastening bolt 5 and a long handle protection bolt 6. The long handle fastening bolt 5 and the long handle protection bolt 6 are both connected to a limiting ring 9, and the distance between the limiting ring 9 and the inner surface of the frame 1 4 is equal to the width of the shovel handle 1;

[0032] The curved frame 7 of the frame 2 8 is also integrally formed, and the connection between the frame 1 4 and the frame 2 8 is further strengthened by the long-handled fastening bolts 5 and the long-handled protective bolts 6. The shovel handle 1 can be fastened to the other side of the frame 1 4 by the limiting ring 9, which is convenient for adjusting the ridge distance.

[0033] A reinforcing plate 10 is connected between the frame 1 4 and the frame 2 8, and the fastening bolts 5 pass through the frame 1 4, the frame 2 8, and the reinforcing plate 10 to fasten them;

[0034] The reinforcing plate 10 further strengthens the connection strength between the frame 1 4 and the frame 2 8 .
