Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, and in particular to a plowshare structure. Background Technology

[0002] A plowshare is an agricultural implement used for tilling the soil. With the continuous development of agricultural automation, plowshares are usually installed on power machinery such as tillers and trailers. To achieve a good harvest, farmers need to till the soil before sowing crops. However, the depth to which seeds are buried varies depending on the crop's needs and geological conditions. Therefore, the plowing depth must be adjusted according to the actual situation. However, the height of existing plowshares is not easily adjustable, resulting in a fixed depth of furrows, which is inconvenient for users. Furthermore, the connection structure between the plowshare and the equipment is complex, making assembly and disassembly time-consuming and laborious, which is detrimental to daily use. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a plowshare structure.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a plow head structure, including a connecting frame, a plow rod is installed at the rear end of the connecting frame, a plurality of first pin holes are opened on the plow rod, a first connecting pin that matches the plurality of first pin holes is installed on the connecting frame, and a plurality of second pin holes are opened at the front end of the connecting frame, and a second connecting pin is installed in the second pin holes.

[0005] Furthermore, a mounting base is fixedly connected to the rear end of the connecting frame. The mounting base has a through mounting groove at both the upper and lower ends. The plow rod is inserted into the mounting groove. Several sets of third pin holes that match the first connecting pin are opened on the left and right side walls of the mounting groove. The third pin holes are arranged in a longitudinal array on the mounting base.

[0006] Furthermore, the bottom of the plow handle is provided with a flat end that is inclined forward, and a wear-resistant plate is detachably installed on the flat end.

[0007] Furthermore, the connecting frame has a hollow structure, and a connecting nut is fixedly connected to the top front end of the connecting frame. A fastening bolt is installed on the connecting nut, and a locking nut is installed on the fastening bolt. A clearance hole corresponding to the position of the connecting nut is opened on the top wall of the connecting frame.

[0008] The beneficial effects of this utility model are that the plow handle of this utility model is fixed by the first connecting pin. By inserting the first connecting pin into the first pin hole at different positions, the height of the plow handle can be flexibly adjusted, which is conducive to the plow head loosening the soil at different depths. This avoids the problem that the height of the traditional plow head is not easy to adjust, and allows the plow head to turn over the soil at different depths. By inserting the connecting frame into the mounting frame on the rear side of the power machinery, and then fixing the position of the connecting frame by the second connecting pin, the convenience of plow head disassembly is improved.

[0016] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0017] according to Figure 1-5As shown, a plow head structure includes a connecting frame 1, a plow rod 2 is installed at the rear end of the connecting frame 1, a plurality of first pin holes 21 are opened on the plow rod 2, a first connecting pin 3 matching the plurality of first pin holes 21 is installed on the connecting frame 1, preferably two sets of first connecting pins 3, a plurality of second pin holes 11 are opened at the front end of the connecting frame 1, and a second connecting pin 4 is installed in the second pin holes 11.

[0018] In this embodiment, a mounting base 5 is welded to the rear end of the connecting frame 1. The mounting base 5 has a through mounting groove 51 at both the upper and lower ends. The plow rod 2 is inserted into the mounting groove 51. Several sets of third pin holes 52 matching the first connecting pin 3 are opened on the left and right side walls of the mounting groove 51. The third pin holes 52 are arranged in a longitudinal array on the mounting base 5. By inserting the first connecting pin 3 into the first pin holes 21 at different positions, the height of the plow rod 2 can be flexibly adjusted, which is beneficial for the plow head to loosen the soil at different depths. This avoids the problem that the height of the traditional plow head is not easy to adjust, and allows the plow head to turn over the soil at different depths.

[0019] In this embodiment, the bottom of the plowshare 2 is provided with a flat end 22 that is inclined forward. A wear-resistant plate 6 is detachably installed on the flat end 22 by bolts. The wear-resistant plate 6 is preferably made of hard alloy. The wear-resistant plate 6 can improve the strength of the plowshare's action on the soil and help extend the service life of the plowshare.

[0020] In this embodiment, the connecting frame 1 has a hollow structure. A connecting nut 7 is welded to the top front end of the connecting frame 1. A fastening bolt 8 is installed on the connecting nut 7 through thread engagement. A locking nut 9 is installed on the fastening bolt 8 through thread engagement. A clearance hole 12 corresponding to the position of the connecting nut 7 is opened on the top wall of the connecting frame 1. The connecting frame 1 is inserted into the mounting bracket on the rear side of the power machinery. Then, the position of the connecting frame 1 is fixed by the second connecting pin 4. The stability between the connecting frame 1 and the mounting bracket is improved by tightening the fastening bolt 8. After tightening the fastening bolt 8, the locking nut 9 is tightened to prevent the fastening bolt 8 from loosening.

[0021] In use, the connecting frame 1 is inserted into the mounting frame on the rear side of the power machinery. The position of the connecting frame 1 is fixed by the second connecting pin 4, which helps to improve the convenience of plow head disassembly. By inserting the first connecting pin 3 into the first pin hole 3 at different positions, the user can flexibly adjust the height of the plow handle 2, which is conducive to the plow head loosening the soil at different depths. This avoids the problem that the height of the traditional plow head is not easy to adjust, and allows the plow head to turn over the soil at different depths.
