Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, and more specifically, it relates to a seeding and loosening disc. Background Technology

[0002] In agricultural planting, reasonable density distribution of seeds can increase yield and reduce planting cost per unit area. Currently, there are a large number of sowing machines in agricultural tools. Before planting, the soil needs to be turned over to improve the germination rate and germination speed. In order to improve sowing efficiency, many soil turning machines are combined with seeders and sowing follows the soil turning.

[0003] For example, the utility model patent with publication number CN208387229U discloses a soil turning and seeding machine, in which soil turning is achieved by rotating the soil turning roller and the soil turning blade. However, the soil turning blade is limited, and after the seeding machine is placed in the field, the soil turning blade does not have the ability to automatically insert into the soil. The insertion depth is based on the weight of the soil turning machine itself, so that the soil turning is based on the surface.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a seeding and loosening disc in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a seeding and soil loosening disc to address the issue that after the seeder is placed in the field, the tilling blades do not have the ability to automatically insert into the soil, and the insertion depth is based on the weight of the tiller itself, resulting in tilling only on the surface.

[0006] The purpose and effect of this utility model's seeding and soil-loosening disc are achieved by the following specific technical means:

[0007] A seeding and loosening soil wheel includes a disc body, which includes two discs connected eccentrically by a connecting cylinder. Multiple forks are provided on the discs away from the eccentric connecting cylinder, and the multiple forks are circumferentially distributed.

[0008] Furthermore, a rotating shaft is inserted inside the connecting cylinder, and brackets are fitted at both ends of the rotating shaft. The tops of the two brackets are connected to the sowing device via connecting plates.

[0009] Furthermore, a transmission wheel is provided on the connecting cylinder.

[0010] Furthermore, the fork body includes two barbs, and the disc has a notch corresponding to the fork body. The two barbs are staggered in the notch, and one end of each barb extends to both sides of the disc.

[0011] Furthermore, a vertical shaft is provided on one side of the notch, and the ends of the two barbs are sleeved on the vertical shaft. A threaded hole is provided on the inner wall of the other side of the notch, and a pin is threaded into the threaded hole.

[0012] Furthermore, the edge of the disk is shaped into a cross-section.

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

[0014] By using the design of the eccentric connecting cylinder between the discs, the discs will move up and down within a certain range during the rotation of the disc body. During the movement and soil turning of the seeder, the discs will repeatedly insert themselves into the soil and retract after turning the soil. After rotating to the next cycle, they will insert themselves into the soil again. It does not rely entirely on the weight of the seeder itself, and the mechanical rotation can insert itself into the soil, thus increasing the soil turning depth. Attached Figure Description

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides a seeding and loosening soil wheel, including two discs 1. The two discs 1 are connected by a connecting cylinder 2 at an eccentric position to form the disc body. The discs 1 and the connecting cylinder are both welded together by metal.

[0026] A rotating shaft 3 is inserted inside the connecting cylinder 2. A bracket 4 is fitted at both ends of the rotating shaft 3. The tops of the two brackets 4 are connected to the sowing device through a connecting plate 5. The sowing device is placed in the field, and the disc 1 is in contact with the soil. Due to the design of the connecting cylinder 2 with the disc 1 at an eccentric position, the disc 1 will move up and down within a certain range during the rotation of the disc body. During the movement and turning of the soil by the sowing device, the disc 1 will repeatedly insert itself into the soil and turn it back after turning it. After rotating to the next revolution, it will insert itself into the soil again, which increases the turning depth.

[0027] The rotation of the disc body is achieved by a transmission wheel 6 provided on the connecting cylinder 2. In this embodiment, the transmission wheel 6 is a sprocket. The sowing device can be equipped with a motor to drive another sprocket, and the two sprockets are connected and driven by a chain.

[0028] The disc 1 is provided with multiple forks at a distance from the eccentric connecting cylinder 2. The multiple forks are distributed circumferentially. During the rotation of the disc 1, the forks can turn over the soil, and the edge of the disc 1 forms a cut surface 101, which allows the disc 1 to be inserted into the soil more smoothly.

[0029] like Figure 2 and Figure 3 As shown, the fork body includes two barbed blades 7. The disc 1 has a notch 102 corresponding to the fork body. The two barbed blades 7 are staggered in the notch 102. The length of the notch 102 is adapted to the length of the barbed blades 7. One end of each of the two barbed blades 7 extends to both sides of the disc 1. The two barbed blades 7 form a fork shape to turn over the soil.

[0030] In this embodiment, the barbed piece 7 is rotatable. A vertical shaft 104 is provided on one side of the notch 102. The ends of the two barbed pieces 7 are sleeved on the vertical shaft 104. The barbed pieces 7 can rotate and swing around the vertical shaft 104, which can retract into the notch 102, reduce the space occupied, and avoid injury to people when handling them during disassembly.

[0031] During the soil turning process, in order to prevent the barbs 7 from retracting into the notch 102 and to ensure that the two barbs 7 swing only on one side, a threaded hole 103 is provided on the inner wall of the other side of the notch 102. A pin 8 is threaded into the threaded hole 103. The pin 8 can be screwed out and placed inside the notch 102 to block the front end of the barb 7 and prevent the front end of the barb 7 from swinging back into the notch 102. The front end of the barb 7 is outside the notch 102 and will be pushed during contact with the soil to keep it in an extended state.

[0032] The notch 102 restricts the swing range of the rotating end of the barb 7, keeping it in a forked shape at a certain angle.

[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
