Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a split spoon wheel seeding disc for sesbania precision sowing. Background Art

[0002] With the increase of labor costs in the planting industry, the demand for mechanized operation equipment is increasing. Due to the diversity of crop seed shapes, biological characteristics and agronomic requirements, the current planting machinery has a narrow scope of application. Some crops are limited by funds and technology and do not have special planting machinery. The mechanized planting effect of these crops is not good and even a lot of labor needs to be done manually. As a widely used mechanical precision seeding device, the spoon-type seeding device mainly sends seeds into the seed guide wheel through the seeding disc and then discharges the seeds. It has the advantages of no damage to seeds during operation, no seed cleaning device, reliable seeding performance, and high precision sowing rate. For example, the special seeding device for single-grain sowing of sorghum disclosed in Chinese utility model patent CN202455799U includes a seeding disc and a seeding spoon head; the seeding spoon head includes a spoon head and a spoon handle. The spoon handle consists of a bottom surface, a left waist surface, a right waist surface, an upper arc surface, a left cut surface, a right cut surface, and a right waist cut surface. The spoon head consists of a spoon head arc surface, a spoon head bottom surface, and a spoon tip; it can ensure that a single sorghum seed can be evenly placed in the hole. However, the seeding tray of the seeding device is connected to the seeding spoon head in an integrated manner. The existing seeding device is inconvenient to use for different seed sowing spacing requirements or parts damage. In addition, since sesbania seeds have the characteristics of small particle size, flat round shape, light weight, etc., using the existing smallest size seeding tray for sesbania sowing still has problems such as poor seed dispersion, which cannot meet the agronomic requirements of sesbania seed precision sowing, and seriously restricts the mechanized planting of sesbania. The purpose of the utility model is to solve the problem of sesbania precision sowing and improve the versatility of the seeding tray. Utility Model Content

[0023] See also Figure 1-Figure 7 A split spoon wheel seeding disc for sesbania precision sowing includes a disc body 1 and a spoon body 2. The seeding device on the seeder (including an outer shell 6, a seed wheel cavity 7, an annular partition 8 and a transparent cover 10 and other structures) is a prior art. The utility model mainly improves the seeding disc in the seeding device body.

[0024] In the present invention, the rotation axis direction of the disc body 1 is defined as the left-right direction, the discharge port of the seed meter is located at the lower side of the outer shell 6, and the direction opposite to the lower position is defined as the upper direction.

[0025] In one embodiment of the utility model, the disk body 1 is in the shape of a disk, the spoon body 2 is in the shape of a spoon-type clamping tooth, and the spoon body 2 is detachably mounted on the side of the disk body 1; a plurality of mounting grooves 3 are evenly arranged at equal intervals on the circumferential side of the disk body 1; a threaded hole 4 is provided on the side of the mounting groove 3; one end of the spoon body 2 is located in the mounting groove 3 and is detachably connected to the disk body 1 by bolts, and the other end of the spoon body 2 extends out of the mounting groove 3 from the mounting groove 3; the spoon body 2 includes a spoon handle 201 detachably connected to the disk body 1 at one end and a spoon head 202 arranged at the other end of the spoon handle 201; a spoon mouth 203 for accommodating field sesbania seeds is provided on the spoon head 202; and a slope 204 is provided on the back of the spoon body 2 along its length direction. The spoon handle 201 and the spoon head 202 are integrally formed structures. At least three countersunk holes 5 for connecting with a seed metering device are provided on the disk body 1.

[0026] The utility model discloses a split-type spoon wheel seeding disk for precision seeding of sesbania, which can realize the separation of the spoon body 2 and the disk body 1. The replaceable spoon body 2 is to adapt to the physical characteristics and seeding requirements of different seeds. For example, different seeds are of different sizes, and some require one seed per hole, while others require several seeds per hole, which requires different sizes of the spoon mouth 203, and reducing or increasing the spoon body 2 can indirectly control the seeding spacing. In response to the seeding spacing requirements of different seeds or the situation of damaged parts, only the corresponding spoon body 2 needs to be replaced, which is lower in cost and more versatile than the integrated seeding disk. The spoon head 202 of the spoon body 2 of the present invention is provided with a spoon mouth 203 for accommodating sesbania seeds, so that the spoon body 2 can screw 3 to 5 sesbania seeds into the spoon mouth 203 at one time when the disk body 1 rotates, so as to meet the requirements of sesbania seeding.

[0027] The spoon handle 201 includes a mounting portion detachably connected to the plate body 1, the spoon head 202 forms a boss upward, and the upper part of the boss is concave to form a spoon mouth 203; the spoon mouth 203 is inclined downward toward the discharge direction of one side of the spoon mouth 203. According to the requirements for sowing sesbania and the physical properties of sesbania seeds, in this embodiment, the spoon mouth 203 is roughly 1 / 4 cylindrical, the diameter of the cylinder is 8 mm, and the center line of the cylinder is 12 mm long.

[0028] The circumferential side of the disk body 1 is evenly and evenly provided with 24 mounting grooves 3; Figure 6 As shown, in this embodiment, based on the embodiment 1, one spoon body 2 is reduced for each interval, and finally reduced to 12 spoon bodies 2, which indirectly changes the adjustment range of the sowing spacing of the seeder. According to this method, the spoon body 2 can be freely disassembled and assembled to meet actual needs.

[0029] When using a split scoop wheel seeding disc for precision seeding of sesbania, the scoop handle 201 of the scoop body 2 is first installed in the installation groove 3 of the disc body 1 to cooperate and realize the limiting effect, and the connection is achieved through round head bolts. After the scoop body 2 is connected to the disc body 1, the seeding disc is installed on the wheel seeding device for seeding operation.

[0030] In another embodiment of the utility model, a spoon wheel seeding device is provided, such as Figure 7, including an outer shell 6, a seed wheel cavity 7, an annular partition 8, a seeding disc 9 and a transparent cover 10; a sowing port is provided at the bottom of the outer shell 6, a seed inlet 11 is provided on the annular partition 8, the seed wheel cavity 7, the annular partition 8 and the seeding disc are sequentially installed in the outer shell 6, the transparent cover 10 is installed on the other side of the outer shell 6, and a feed inlet is provided thereon, and the seeding disc adopts a split spoon wheel seeding disc for precision sowing of sesbania in any of the aforementioned embodiments. When the disc body 1 of the seeding disc 9 rotates, the spoon body 2 passes through the seed inlet 11; the spoon mouth 203 of the spoon head 202 is inclined toward the end where the seed inlet 11 is located, so that when the seeds at the spoon mouth 203 pass through the seed inlet 11, the seeds at the spoon mouth 203 slide into the seed chamber of the seed wheel cavity 7 under the action of gravity, and then are discharged through the sowing port at the bottom of the outer shell 6.

[0031] As the disc body 1 rotates, the spoon mouth 203 of the spoon body 2 can bring the small sesbania seeds in the shell to the seed inlet 11 at a spoonful of 3 to 5 seeds; since the spoon mouth 203 is inclined, the sesbania seeds carried by the spoon mouth 203 will slide into the seed chamber of the seed wheel cavity 7 when passing through the seed inlet 11; since the back of the spoon body 2 is provided with a slope 204 along its length direction, the sesbania seeds will slide on the slope 204 to the bottom of the disc body when the seed disc is running, so as to reduce the accumulation of seeds on the back of the spoon body 2 and avoid chuck.
