Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a green manure seed covering device. Background Technology

[0002] Currently, soil covering devices are used in existing agricultural machinery and equipment. They are mainly used after sowing seeds in furrows to combine the soil on both sides of the furrow into a line, that is, to cover the seeds with soil in one place, and then the ground wheel is used to compact the soil to complete the one-time sowing operation.

[0003] Patent CN219019507U discloses a soil covering device for a mulching seeder, comprising: soil covering device side plates, a pin fixedly installed between two soil covering device side plates, mounting components for connecting the seeder at both ends of the pin, and a spacing adjustment mechanism at the end of each of the two soil covering device side plates away from the pin. The soil covering device for a mulching seeder provided in this application facilitates the connection between the soil covering device side plates and the seeder by horizontally inserting the mounting components at both ends of the pin into two insertion holes on the inner wall of the seeder frame, thereby effectively improving the convenience of installing the soil covering device. The spacing adjustment mechanism allows for easy adjustment of the spacing between the two connecting plates, thereby adjusting the spacing between the two soil covering discs and effectively improving the flexibility of the soil covering device.

[0004] However, the above technology still has the following problems:

[0005] During the process of trenching, soil is pushed to both sides of the trench. If the soil in the un-trenched area is hard, the double disc cover will not be effective. In addition, the existing cover size is fixed and cannot be adjusted according to the width of the trench. Furthermore, it cannot be effectively used after the machinery is damaged. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a green manure seed covering device with adjustable width and can be used on soil with different hardness.

[0007] This utility model provides the following technical solution: a green manure seed covering device, including a baffle, a fixed plate fixedly connected to the baffle, a sliding cavity opened on the fixed plate, two mutually symmetrical side blocking mechanisms slidably connected in the sliding cavity, two mutually symmetrical sliding grooves opened on the fixed plate, both sliding grooves communicating with the sliding cavity, a slider fixedly connected to the side blocking mechanism, the slider slidably connected to the sliding groove, a driving mechanism for driving the slider to move fixedly connected to the fixed plate, a fixed seat fixedly connected to the fixed plate, and a gripping component detachably connected to the fixed seat.

[0008] Furthermore, the side stop mechanism includes a slide plate slidably connected within the slide cavity, a side plate fixedly connected to the front end of the slide plate, and a slider fixedly connected to the slide plate.

[0009] Furthermore, the driving mechanism includes two rotating blocks fixedly connected to the middle position of the fixed plate, a bidirectional lead screw rotatably connected to the two rotating blocks, a turntable fixedly connected to the bidirectional lead screw, the turntable being located between the two rotating blocks, and a slider threadedly connected to the bidirectional lead screw.

[0010] Furthermore, both ends of the bidirectional lead screw are threaded with hexagonal nuts.

[0011] Furthermore, the fixing base includes a connecting block fixedly connected to the fixing plate, and the connecting block has a threaded hole.

[0012] Furthermore, the gripping assembly includes a threaded rod threaded onto a threaded hole, and a gripping rod is fixedly connected to the threaded rod.

[0013] Furthermore, an annular plate is fixedly connected to the gripping rod, and an anti-slip and wear-resistant pad is fixedly connected to the surface of the annular plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This green manure seed covering device allows for adjustment of the distance between the two side guard mechanisms to accommodate trenches of varying widths. Additionally, when there is no seeper frame, traction device, or power system, this device can be connected to the gripping assembly, allowing the user to press and pull it to push the soil from both sides of the trench into the trench to cover the green manure seeds.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 A green manure seed covering device includes a baffle 1, a fixed plate 2 fixedly connected to the baffle 1, a sliding cavity 3 opened on the fixed plate 2, two mutually symmetrical side blocking mechanisms slidably connected in the sliding cavity 3, two mutually symmetrical sliding grooves 4 opened on the fixed plate 2, both sliding grooves 4 communicating with the sliding cavity 3, a slider 5 fixedly connected to the side blocking mechanism, the slider 5 slidably connected to the sliding groove 4, a driving mechanism for driving the slider 5 to move fixedly connected to the fixed plate 2, a fixed seat fixedly connected to the fixed plate 2, and a gripping component detachably connected to the fixed seat.

[0022] The green manure seed covering device in this utility model is similar in structure to the covering device used in existing mulching seeders. For example, patent CN219019507U discloses a covering device for a mulching seeder. The main improvement of this utility model is that its width is adjustable to suit trenches of different widths. Furthermore, this device can be used manually even when there is no seeder frame, traction device, or power system. Figures 1 to 3 As shown, the green manure seed covering device of this utility model can be used to adjust the distance between the two side baffle mechanisms in the sliding cavity 3 through the drive mechanism to adapt to trenches of different widths. At the same time, this device is usually connected to the frame, traction device or power system of the seeder. When there is no seeder frame, traction device or power system, the gripping component can be connected to the fixed base. The user presses and pulls it to make the soil gather between the baffle 1 and the two side baffle mechanisms. The two side baffle mechanisms are located on both sides of the trench, so that the gathered soil falls from below the baffle 1 into the trench to cover the green manure seeds. At the same time, the baffle 1 and the side baffle mechanisms can also make the soil above the green manure seeds smooth.

[0023] like Figures 1 to 3 As shown, the side blocking mechanism includes a slide plate 6 slidably connected in the slide cavity 3, a side plate 7 fixedly connected to the front end of the slide plate 6, and a slider 5 fixedly connected to the slide plate 6.

[0024] Specifically, the slide plate 6 is slidably connected inside the slide cavity 3. The slide cavity 3 can limit the slide plate 6. When the soil applies a force to the side plate 7, the inner wall of the slide cavity 3 will generate a reaction force on the slide plate 6. The side plate 7 is used to collect and guide the soil on the side of the trench, so that the soil moves along the surface of the side plate 7 toward the middle of the trench.

[0025] like Figure 2As shown, the driving mechanism includes two rotating blocks 8 fixedly connected to the middle position of the fixed plate 2. A bidirectional lead screw 9 is rotatably connected to the two rotating blocks 8. A turntable 10 is fixedly connected to the bidirectional lead screw 9. The turntable 10 is located between the two rotating blocks 8. The slider 5 is threadedly connected to the bidirectional lead screw 9.

[0026] Specifically, rotating the turntable 10 causes the bidirectional lead screw 9 to rotate, thereby driving the two sliders 5 to move along the bidirectional lead screw 9 in opposite directions.

[0027] like Figure 1 As shown, both ends of the bidirectional lead screw 9 are threaded with hexagonal nuts 11.

[0028] Specifically, the hexagonal nut 11 can prevent the two slide plates 6 from slipping off the slide cavity 3. At the same time, after removing the hexagonal nut 11, it is convenient to remove the two side guard mechanisms for cleaning and replacement.

[0029] like Figure 1 As shown, the fixing base includes a connecting block 12 fixedly connected to the fixing plate 2, and the connecting block 12 has a threaded hole 13.

[0030] Specifically, the connecting block 12 is used to connect with the fixing plate 2, and the threaded hole 13 is used to connect the gripping assembly.

[0031] like Figure 2 As shown, the gripping assembly includes a threaded rod 14 threadedly connected to a threaded hole 13, and a gripping rod 15 is fixedly connected to the threaded rod 14.

[0032] Specifically, when there is no frame, traction device or power system of the seeder, the threaded rod 14 can be threaded to the threaded hole 13 on the fixed seat. The user presses and pulls the gripping rod 15, so that the soil is gathered between the baffle 1 and the two side baffle mechanisms. The two side baffle mechanisms are located on both sides of the trench, so that the gathered soil falls from below the baffle 1 into the trench to cover the green manure seeds.

[0033] like Figure 2 As shown, an annular plate 16 is fixedly connected to the gripping rod 15, and an anti-slip and wear-resistant pad 17 is fixedly connected to the surface of the annular plate 16.

[0034] Specifically, the anti-slip and wear-resistant pad 17 can increase the friction between the annular plate 16 and the connecting block 12, making it difficult for the threaded rod 14 and the threaded hole 13 to rotate easily.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
