Description

Technical Field

[0001] A hole seeder and a soil knocker thereof relate to the field of agricultural machinery, in particular to a hole seeder. Background Art

[0002] The hole seeder in the prior art does not have a duckbill soil knocking device. The existing technical problem is that during sowing, due to different regional soil conditions, soil and weeds will continue to adhere to the duckbill of the hole seeder, causing the duck to have problems such as poor film breaking, insufficient seeding depth, and seed drifting during the sowing process, which seriously affects the sowing efficiency and progress. Summary of the invention

[0003] The technical problem to be solved by the invention is to remove clay, weeds and the like on the duckbill of a hole seeder.

[0004] In order to solve the above technical problems, the present invention provides the following two inventions.

[0005] The first invention.

[0006] A soil knocker 1 comprises a fixed plate 2, a movable plate 3, a rolling wheel 4 and a torsion spring 5; the torsion spring 5 comprises a main force arm 6 and a force-bearing arm 7; the fixed plate 2 comprises a middle plate 9 connecting two parallel side plates 8, and a circular hole 10 passes through the two side plates 8; the movable plate 3 comprises a transverse plate 12 connecting two parallel straight plates 11, a through hole 13 and a concentric hole 14 pass through the straight plate 11, the rolling wheel 4 is installed between the concentric holes 14 by means of bolts 15, and the torsion spring 5 is installed between the through holes 13; the screw rod 16 passes through the circular hole 10 of the fixed plate 2, the through hole 13 of the movable plate 3, and the middle part of the torsion spring 5 in sequence, the main force arm 6 of the torsion spring 5 is in contact with the middle plate 9, and the force-bearing arm 7 is in contact with the transverse plate 12; the straight plate 11 is in clearance with the middle plate 9, and the transverse plate 12 is in line contact with the middle plate 9 when it is perpendicular, so as to jointly restrict the movable plate 3 from rotating in the working state only with the screw rod 16 as the axis in the area below the horizontal line, and cannot rotate in the area above the horizontal line.

[0007] Further, the number of the circular holes 10 is two.

[0008] Furthermore, there are two load-bearing arms 7.

[0009] The second invention.

[0010] A hole drill 17 comprises the hole drill 17 and the above-mentioned soil knocker 1, wherein the hole drill 17 is connected to the soil knocker 1, and when in working state, the rolling wheel 4 faces the hole drill 17 and cooperates with the dovetail plate 19 of the duckbill 18.

[0011] Further, the horizontal plate 12 is placed horizontally. The working state refers to when the seed drill is sowing.

[0012] Furthermore, one end of the connecting rod 20 is connected to the soil drill 17 , and the other end is connected to the soil knocker 1 .

[0013] Furthermore, the upper part of the connecting rod 21 of the seed drill 17 is fixedly connected to a vertical plate 22 , and two holes 23 on the vertical plate 22 are respectively connected to the L-shaped opening 24 and the opening 25 of the connecting rod 20 through bolts 15 .

[0014] Furthermore, a circular hole 26 perpendicular to the plane where the connecting rod 20 is located is provided on the connecting rod 20 , and the screw rod 16 passes through the circular hole 26 .

[0015] Furthermore, the number of circular holes 10 is two, and the connecting rod 20 is provided with a circular hole 26 and a notch 27 perpendicular to the plane where the connecting rod 20 is located, one circular hole 10 and the circular hole 26 are connected by a bolt 15, and the other circular hole 10 and the notch 27 are connected by a screw 16. The L-shaped opening (24), opening (25), and notch (27) of the present invention are all for the purpose of facilitating disassembly and installation, and in fact, circular holes and the like can also achieve the purpose of the invention.

[0016] The beneficial effects achieved by the invention are: the clay 28 on the duckbill 18 is removed; the absence of clay 28 on the duckbill 18 is conducive to breaking the film and stabilizing the seeding depth. At the same time, after the soil knocker 1 is installed, the soil knocker 1 does not need to be removed when the seed drill 17 is not working, and the seed drill 17 can still be reversed.
