Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting machinery, and in particular to a depth-adjustable high-efficiency sowing device for Chinese medicinal plant planting. Background Art

[0002] As people pay more and more attention to traditional Chinese medicine, the corresponding Chinese medicine is also in demand by more people. When planting Chinese medicine, it is necessary to dig a hole first, then put the Chinese medicine seeds into the hole, and then cover the soil, water and other operations. Although there are corresponding machines that can perform the above simple operations, multiple machines are required to be used separately, and each machine requires corresponding personnel to operate. The convenience of operation needs to be improved. At the same time, the digging device cannot dig seed holes of different depths according to the different planting needs of Chinese medicine seeds. For this reason, we propose an efficient sowing device for Chinese medicine planting with adjustable depth. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem in the prior art that planting cannot be carried out when digging a hole, and to propose a high-efficiency sowing device for Chinese medicinal planting with adjustable depth.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A high-efficiency sowing device for Chinese medicinal plant planting with adjustable depth, comprising a frame with handrails;

[0006] A plurality of wheels are rotatably mounted on the frame via two connecting rods, a roller is rotatably mounted on the connecting rod close to the handrail, and a loosening structure is mounted on the connecting rod away from the handrail;

[0007] A water tank is fixedly mounted on the frame, a water inlet pipe is fixedly connected to the water tank, a rotary excavation water outlet structure is cooperatively mounted between the water tank and the frame, a plurality of short columns are mounted on the rotary excavation water outlet structure, a mounting plate is fixedly mounted on the lower ends of the plurality of short columns, a planting structure used in conjunction with the rotary excavation water outlet structure is mounted on one end of the mounting plate, the planting structure is used to place seeds into the corresponding seeding pits after digging a pit, and a soil covering structure is mounted on the other end of the mounting plate;

[0008] The lower surface of the frame is provided with an annular stepped groove, a stepped rod is slidably provided on the stepped groove, a telescopic rod is fixedly installed on the lower end of the stepped rod, and the lower end of the telescopic rod is fixed to the mounting plate.

[0009] Compared with the existing technology, the advantages of the present invention are:

[0010] 1: When planting Chinese medicinal materials, it has the advantage of loosening the soil before planting. Through the setting of multiple rotary digging teeth on the drum, the soil can be loosened before the equipment digs the pit. At the same time, the hard bumps or stones on the surface can be processed, so that the subsequent digging work can be carried out better, and it can promote the decomposition of organic matter, increase the soil nutrient supply capacity, and is beneficial to the survival of Chinese medicinal materials.

[0011] 2: When planting Chinese medicinal materials, it has the advantage of shoveling the soil in the foundation pit. Through the setting of multiple grab hooks and baffles, with the cooperation of the worm gear and the worm, the structure is lifted and lowered to complete the digging work of the land. At the same time, with multiple water pipes, the pit can be watered while digging. In the process of moving the equipment, the soil in the pit can be grabbed by the rising of the mounting plate, which improves the survival rate of Chinese medicinal materials after planting and provides convenience for the planting work of personnel.

[0012] 3: When planting Chinese medicinal materials, it has the advantage of being able to plant after the pit is dug. Through the setting of the threaded barrel, the Chinese medicinal materials can be planted after the equipment has completed digging the pit. By utilizing the rotation of the equipment during operation, the upper and lower feeding rods can be coordinated to complete regular planting work. At the same time, by utilizing the setting of multiple columns, the foundation pit can be covered with soil after the Chinese medicinal materials are planted, thereby achieving the continuity of the entire planting process.

[0013] 4: When planting Chinese medicinal materials, it has the advantage of leveling or covering the soil after planting. Through the setting of the roller, the soil dug out of the pit or the raised soil can be leveled and compacted to a certain extent after the planting of Chinese medicinal materials is completed, so that the soil on the surface of the Chinese medicinal materials is more evenly covered. For Chinese medicinal materials that need to be covered, it is only necessary to replace the roller with a plastic film, and the covering can be carried out simultaneously by moving the equipment.

[0014] To sum up, the present invention loosens the soil on the planting ground and then digs a hole. While digging the hole, it cooperates with the movement of the equipment to realize the planting of traditional Chinese medicine. After the planting is completed, the traditional Chinese medicine foundation pit is covered with soil, and the covered soil is flattened, so that the planting process is carried out efficiently, which provides convenience for the planting of traditional Chinese medicine.
