Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and specifically relates to a soil covering mechanism for agricultural machinery. Background Technique

[0002] Agricultural machinery, that is, agricultural implements, refers to various mechanical equipment and tools used in the process of agricultural production. Agricultural planting often needs to be carried out through agricultural machinery, and in agricultural planting, in order to better cultivate soil and keep moisture, soil is often covered on the seeds after planting, so that the seeds can be better buried in the soil, greatly improving the survival rate of the seeds.

[0003] In the prior art, generally, a disc-type soil covering device is used to cover and level the planting ditch. However, generally, the angle between the two discs of the disc-type soil covering device is fixed, and thus the amount of soil covering cannot be controlled according to the actual situation. Therefore, it is necessary to propose a soil covering and leveling device for a medicinal material planting machine to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a soil covering mechanism for agricultural machinery, which has the characteristics of being convenient to adjust the angle between the two discs, so as to control the amount of soil covering according to the actual situation.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A soil covering mechanism for agricultural machinery includes a box body and two discs symmetrically distributed left and right. The bottom end of the inner wall of the box body is rotatably connected with two axles distributed left and right. The upper ends of the two axles are fixedly connected with connecting discs. The outer walls of the two connecting discs are fixedly connected with externally meshing external gear rings. Two connecting blocks are arranged below the box body. The lower ends of the two connecting blocks are fixedly connected with connecting columns. The two discs are respectively rotatably connected to the outer walls of the two connecting columns;

[0006] A pre-tightening mechanism is arranged at the upper end of the connecting disc on the right side;

[0007] Locking mechanisms are arranged between the two connecting blocks and the two axles.

[0008] In order to limit the rotation of the external gear ring and the connecting disc on the right side, as a preferred soil covering mechanism for agricultural machinery of the utility model, the pre-tightening mechanism includes a turntable fixedly connected to the upper end of the connecting disc on the right side and rotatably connected to the upper end of the inner wall of the box body. A second round hole is penetrated through the upper end of the box body. The upper end of the turntable is fixedly connected with a second screw rod passing through the second round hole. The outer wall of the second screw rod is threadedly connected with a second hexagonal nut that presses against the upper end of the box body.

[0009] To protect the two external gear rings, as an optimization of the soil covering mechanism for agricultural machinery in the present utility model, the locking mechanism includes two first round holes penetrating through the lower end face of the box body. The lower ends of the two rotating shafts are fixedly connected with first screws passing through the two first round holes, and the outer walls of the two first screws are threadedly connected with first hexagonal nuts pressing against the lower end face of the box body.

[0010] To facilitate the rotation of the second screw, as an optimization of the soil covering mechanism for agricultural machinery in the present utility model, the upper end of the second screw is fixedly connected with a holding handle.

[0011] To facilitate the installation of the device on agricultural machinery, as an optimization of the soil covering mechanism for agricultural machinery in the present utility model, the upper end of the box body is fixedly connected with a fixing column, and the upper end of the fixing column is fixedly connected with an installation frame.

[0012] To facilitate the connection and fixation of the two connecting blocks and the two first screws, as an optimization of the soil covering mechanism for agricultural machinery in the present utility model, the two connecting blocks are respectively fixedly connected to the lower ends of the two first screws.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Make the right connecting disk rotate clockwise along with the right rotating shaft, thereby driving the right external gear ring to rotate clockwise. At the same time, cooperate with the left external gear ring to drive the left connecting disk to rotate counterclockwise along with the left rotating shaft. At the same time, promote the right disk and the left disk to rotate clockwise and counterclockwise respectively, thereby reducing the angle between the two disks, and the soil is more concentratedly pushed into the sowing ditch or planting row, thereby increasing the soil covering amount per unit area. On the contrary, when the right connecting disk rotates counterclockwise along with the right rotating shaft, the angle between the two disks can be increased, so that the soil covering amount per unit area is reduced because the soil is more dispersed over a larger area. Then, through the pre-tightening mechanism, the rotation of the right external gear ring and the right connecting disk can be restricted, thereby fixing the angular positions of the two disks. Subsequently, the two locking mechanisms can protect the two external gear rings, further achieving the purpose of facilitating the adjustment of the angle between the two disks, thereby controlling the soil covering amount according to the actual situation.

Detailed implementation mode

[0019] Please refer to Figures 1 to 3 , a soil covering mechanism for agricultural machinery, including a box body 1 and two disks 10 symmetrically distributed left and right. The bottom end of the inner wall of the box body 1 is rotatably connected with two rotating shafts 2 distributed left and right. The upper ends of the two rotating shafts 2 are fixedly connected with connecting disks 3. The outer walls of the two connecting disks 3 are fixedly connected with externally meshing external gear rings 4. Two connecting blocks 8 are arranged below the box body 1. The lower ends of the two connecting blocks 8 are fixedly connected with connecting columns 9. The two disks 10 are respectively rotatably connected to the outer walls of the two connecting columns 9;

[0020] A pre-tightening mechanism is arranged at the upper end of the right connecting disk 3;

[0021] Locking mechanisms are arranged between the two connecting blocks 8 and the two rotating shafts 2.

[0022] In this embodiment: During use, the right connecting disk 3 rotates clockwise along with the right rotating shaft 2, thereby driving the right external gear ring 4 to rotate clockwise. At the same time, in cooperation with the left external gear ring 4, it can drive the left connecting disk 3 to rotate counterclockwise along with the left rotating shaft 2. And since the two external gear rings 4 have the same size and specifications, the two rotating shafts 2 can rotate at the same speed. At the same time, it drives the right first screw 6 to rotate clockwise and the left first screw 6 to rotate counterclockwise, and drives the right connecting block 8, the right connecting column 9 and the right disk 10 to rotate clockwise, and at the same time promotes the left connecting block 8, the left connecting column 9 and the left disk 10 to rotate counterclockwise. Thus, the angle between the two disks 10 can be reduced, and the soil is more concentratedly pushed into the sowing ditch or planting row, thereby increasing the soil covering amount per unit area. On the contrary, when the right connecting disk 3 rotates counterclockwise along with the right rotating shaft 2, the angle between the two disks 10 can be increased, so that the soil covering amount per unit area is reduced because the soil is more dispersed over a larger area. After adjusting the angle of the two disks 10, the pre-tightening mechanism can limit the rotation of the right external gear ring 4 and the right connecting disk 3, thereby fixing the angular position of the two disks 10. Subsequently, the two locking mechanisms can respectively prevent the two rotating shafts 2 from rotating, thereby protecting the two external gear rings 4 by restricting the rotation of the two external gear rings 4, and further achieving the purpose of facilitating the adjustment of the angle between the two disks 10, so as to control the soil covering amount according to the actual situation.

[0023] As a technical optimization solution of the present utility model, the pre-tightening mechanism includes a turntable 11 fixedly connected to the upper end of the right connecting disk 3 and rotatably connected to the upper end of the inner wall of the box body 1. A second circular hole 12 is penetrated and opened at the upper end of the box body 1. A second screw rod 13 is fixedly connected to the upper end of the turntable 11 and passes through the second circular hole 12. A second hexagonal nut 14 that is in extrusion contact with the upper end of the box body 1 is threadedly connected to the outer wall of the second screw rod 13.

[0024] In this embodiment: By rotating the second screw rod 13, the turntable 11 is driven to rotate, and then the right connecting disk 3 can be driven to rotate.

[0025] After the angles of the two disks 10 are adjusted, keep the second screw rod 13 from rotating, and rotate the second hexagonal nut 14 with a wrench, so that the second hexagonal nut 14 is in close contact with the upper end of the box body 1, thereby restricting the rotation of the turntable 11, the right outer gear ring 4 and the right connecting disk 3.

[0026] As a technical optimization solution of the present utility model, the locking mechanism includes two first circular holes 5 penetrated and opened on the lower end surface of the box body 1. The lower ends of the two rotating shafts 2 are both fixedly connected with first screw rods 6 that pass through the two first circular holes 5. First hexagonal nuts 7 that are in extrusion contact with the lower end surface of the box body 1 are threadedly connected to the outer walls of the two first screw rods 6.

[0027] In this embodiment: After pre-tightening, rotate the two first hexagonal nuts 7 with a wrench, so that they are in close extrusion contact with the lower end surface of the box body 1, thereby preventing the two rotating shafts 2 from rotating respectively, and achieving the purpose of protecting the two outer gear rings 4 by restricting the rotation of the two outer gear rings 4.

[0028] As a technical optimization solution of the present utility model, a holding handle 15 is fixedly connected to the upper end of the second screw rod 13.

[0029] In this embodiment: By providing the holding handle 15, it is convenient to rotate the second screw rod 13.

[0030] As a technical optimization solution of the present utility model, a fixed column 16 is fixedly connected to the upper end of the box body 1, and a mounting bracket 17 is fixedly connected to the upper end of the fixed column 16.

[0031] In this embodiment: By providing the fixed column 16, it is convenient to connect the mounting bracket 17, and the device can be installed on agricultural machinery through the mounting bracket 17.

[0032] As a technical optimization solution of the present utility model, two connecting blocks 8 are respectively fixedly connected to the lower ends of the two first screw rods 6.

[0033] In this embodiment, by fixedly connecting two connecting blocks 8 to the lower ends of two first screws 6 respectively, it is convenient to connect and fix the two connecting blocks 8 and the two first screws 6.

[0034] Working principle: When in use, first rotate the second screw 13 by holding the handle 15, which drives the turntable 11 to rotate, and then drives the right connecting disk 3 to rotate clockwise along with the right rotating shaft 2, and then drives the right external gear ring 4 to rotate clockwise. At the same time, cooperating with the left external gear ring 4, it can drive the left connecting disk 3 to rotate counterclockwise along with the left rotating shaft 2. And because the two external gear rings 4 have the same size and specifications, the two rotating shafts 2 can rotate at the same speed. At the same time, it drives the right first screw 6 to rotate clockwise and the left first screw 6 to rotate counterclockwise, and drives the right connecting block 8, the right connecting column 9 and the right disk 10 to rotate clockwise. And at the same time, it causes the left connecting block 8, the left connecting column 9 and the left disk 10 to rotate counterclockwise. Thus, the angle between the two disks 10 can be reduced, and the soil is more concentratedly pushed into the sowing furrow or planting row, thereby increasing the soil covering amount per unit area. On the contrary, when the right connecting disk 3 rotates counterclockwise along with the right rotating shaft 2, the angle between the two disks 10 can be increased, so that the soil covering amount per unit area is reduced because the soil is more dispersed over a larger area. After adjusting the angle of the two disks 10, by holding the handle 15 to keep the second screw 13 from rotating, and turning the second hexagonal nut 14 with a wrench, the second hexagonal nut 14 is tightly abutted against the upper end of the box body 1, so as to restrict the rotation of the turntable 11, the right external gear ring 4 and the right connecting disk 3, and then fix the angular positions of the two disks 10. Then, turn the two first hexagonal nuts 7 with a wrench, so that they are tightly pressed against the lower end surface of the box body 1, and then the rotation of the two rotating shafts 2 can be prevented respectively. Thus, by restricting the rotation of the two external gear rings 4, the purpose of protecting the two external gear rings 4 is achieved, and further the purpose of facilitating the adjustment of the angle between the two disks 10 and thus controlling the soil covering amount according to the actual situation is achieved.

[0035] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
