Description

Technical Field

[0001] The utility model relates to the technical field of crop sowing, in particular to an angle-adjustable crop sowing device. Background Art

[0002] One of the crop cultivation measures is to sow the sowing materials into the soil layer at a certain depth in a certain quantity and manner at the right time. Whether the sowing is appropriate or not directly affects the growth and yield of the crop. In order to improve the sowing quality, in addition to fine land preparation before sowing, seed treatment, as well as preparation of labor, animal power and sowing machinery must be done well.

[0003] There are many existing technologies, such as the angle-adjustable crop sowing device disclosed in publication number CN221576050U. The power box is used to power a low-temperature heat pipe. When the low-temperature heat pipe is activated, the temperature of the space between the inner barrel and the seed barrel increases. After the heat is transferred to the interior of the inner barrel, the seeds are placed from the top of the inner barrel. During the falling process, the seeds will remove the moisture contained in the seeds in an appropriate temperature environment, thereby improving the quality of the seeds. However, the following problems still exist in use:

[0004] By putting crop seeds into the seed barrel and then implanting the seeds into the soil through the discharge barrel, the number density of seeds implanted in the soil cannot be controlled. Since different soil types and different seeds require different planting densities, the above technology cannot sow crops at different densities. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the number density of seeds implanted in the soil cannot be controlled, and to propose an angle-adjustable crop sowing device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0012] Preferably, four support rods for fixing the plowshare are fixedly mounted on the outer wall of the plowshare, and one end of the support rod is fixedly mounted on the lower part of the main bracket.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The utility model places crop seeds into a storage hopper and then turns on a driving motor, so that the driving motor drives the rotating disk to rotate. Through the triangular grooves provided on the rotating disk, the crop seeds flow from the triangular grooves into the through holes provided in the fixed plate during the rotation of the rotating disk.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 5 , an angle-adjustable crop sowing device, comprising a main bracket 1, a support frame 2 fixedly connected to the upper portion of the main bracket 1, a sowing mechanism provided in the support frame 2, and a first mounting plate 9 and a second mounting plate 11 fixedly mounted on both sides of the lower portion of the support frame 2, a guide wheel 10 matchedly mounted between the first mounting plates 9, two pressure wheels 12 symmetrically provided on both sides of the lower portion of the second mounting plate 11, fixed plates 6 symmetrically mounted on both sides of the main bracket 1, a pushing mechanism for pushing the main bracket 1 is provided between the fixed plates 6 and the main bracket 1;

[0024] The sowing mechanism includes a storage hopper 3 for placing crop seeds, a fixed plate 15 is fixedly installed in the storage hopper 3, a through slot for seed circulation is provided in the fixed plate 15, and the through slot is set at an eccentric position of the fixed plate 15. A driving motor 16 is fixedly installed at the lower part of the fixed plate 15, and a rotating disk 17 is fixedly connected to the output end of the driving motor 16. The rotating disk 17 is provided with a triangular groove. The triangular groove and the through slot are on the same vertical plane, so that the crop seeds in the storage hopper 3 flow into the feeding pipe in the plowshare 14. The plowshare 14 with a feeding pipe is fixedly installed at the lower part of the storage hopper 3, and the bottom of the plowshare 14 is provided with a conical structure at the front end. The conical structure provided by the plowshare 14 facilitates turning over the soil so that the seeds are sown into the soil;

[0025] The rotating disk 17 is rotatably mounted on the upper wall of the fixed plate 15, so that the rotating disk 17 rotates so that the triangular grooves of the rotating disk 17 and the through grooves of the fixed plate 15 are on the same vertical plane, so that the crop seeds fall from the storage hopper 3;

[0026] The pushing mechanism includes a rotating shaft 4, a rotating ring 5 is provided on the outer wall of the rotating shaft 4, and an armrest 7 is fixedly connected to the outer wall of the rotating ring 5. By pushing the armrest 7, the main bracket 1 is moved, thereby rotating the guide wheel 10 and the pressure wheel 12, reducing the physical exertion required during sowing. The lower part of the armrest 7 is integrally connected to an electric telescopic rod 8 through a pin shaft;

[0027] The armrests 7 are provided on both sides of the main support 1. By pushing the armrests 7, the force on both sides of the main support 1 is evenly applied to prevent the crop sowing direction from tilting. The lower end of the electric telescopic rod 8 is rotatably connected to the upper wall of the main support 1, making it easy to push the armrests 7 up and down, suitable for people of different heights.

[0028] Four support rods 13 for fixing the plowshare 14 are fixedly installed on the outer wall of the plowshare 14. The four support rods 13 prevent the plowshare 14 from tilting during sowing. One end of the support rod 13 is fixedly installed on the lower part of the main bracket 1.

[0029] The functional principle of this utility model can be explained through the following operation modes:

[0030] According to the desired planting density of the seeds, the driving motor 16 is turned on to drive the rotating disk 17 to rotate. During the rotation of the rotating disk 17, the crop seeds flow from the triangular grooves into the through holes in the fixed plate 15, and finally flow into the plowshare 14, and then fall into the soil through the feed pipe in the plowshare 14.

[0031] When people of different heights use it, the electric telescopic rod 8 is turned on to drive the armrest 7 to move up and down, so that the rotating ring 5 fixedly connected to the other end of the armrest 7 rotates on the rotating shaft 4, so that the height of the armrest 7 is suitable for people of different heights to hold the armrest 7 with both hands to introduce the guide wheel 10 into the field ridge for sowing operations.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
