Description

Technical Field

[0001] The utility model relates to the technical field of corn seeding, in particular to a flat socket cavity seeding wheel. Background Art

[0002] The existing seed wheel socket cavities of corn plot seeders are mostly cylindrical, conical, or hemispherical. The cavities are relatively regular shapes, and are mostly adjusted based on the maximum size of the corn seeds to be sown. In fact, corn seeds are not simplified spherical rigid bodies, but irregular cuboids, and their contour shapes can be described by the dimensions in the length, width, and thickness directions. The conventional seed wheel socket cavities do not take into account the contour shape of the corn, the cavities are regular, and the seed filling window area is designed to be small, which can cause seeds to get stuck in the cavity or make filling difficult. A single adjustment of the cavity size is prone to deviations, resulting in an increase in the reseeding rate or missed seeding rate. Utility Model Content

[0003] The utility model provides a flat socket cavity seed wheel, which enlarges the seed filling area of ​​the cavity, is suitable for accommodating flat seeds such as corn, is conducive to seed filling, and avoids the increase of reseeding rate and missed seeding rate caused by single adjustment of cavity design size.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A flat socket cavity seeding wheel comprises a wheel body, a round head double flat hole, a flat socket cavity, and a seed-moving piece guide groove. The wheel body is cylindrical, with a diameter of 96 mm and a height of 52 mm. The round head double flat hole is arranged at the center of the wheel body, the flat socket cavity is arranged on the outer circumferential surface of the wheel body, and the seed-moving piece guide groove is arranged on the outer circumferential surface of the wheel body.

[0006] Preferably, the round-headed double flat hole is a mounting hole, which is arranged at the center of the wheel body, has a long diameter of 15 mm, a distance between the two end faces of the hole of 13 mm, and a hole depth of 52 mm.

[0007] Preferably, the flat socket cavities are arranged in four rows and arranged in parallel, with the same size and a shape that is a combination of a semi-cylinder and a wedge-like shape. The semi-cylinder and the wedge-like shape have a rectangle as the contact surface, and the two flat socket cavities in each row are symmetrically distributed around the center line of the wheel body.

[0008] Preferably, the flat socket cavity can accommodate a rectangular parallelepiped in the shape of a corn seed in a flat state, with a length equal to the maximum length of the corn seed plus 1.5 mm, a height equal to the maximum thickness of the corn seed plus 1.5 mm, and a width equal to the maximum width of the corn seed plus 3 mm.

[0009] Preferably, there are two seed-pickling plate guide grooves, which are arranged on the outer circumferential surface of the wheel body and are distributed in a circular shape through the middle position of each row of flat socket cavities. The seed-pickling plate guide grooves penetrate 1 to 2 mm into the bottom of the flat socket cavities.

[0010] Preferably, the flat socket cavity seed wheel is made of engineering plastic or carbon steel profile.

[0011] Compared with the prior art, the utility model has achieved the following technical effects: the flat socket cavity designed according to the principle of corn seed profiling can accommodate rectangular-shaped corn seeds, avoiding the problems of small seed filling window of conventional socket cavities, increased reseeding rate and missed seeding rate caused by single adjustment of cavity design size. The flat socket cavity enlarges the seed filling window, but each flat socket cavity can only accommodate a single corn seed, which is conducive to seed filling but not easy to cause reseeding.

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] Example: Figure 1-4 As shown, the utility model provides a technical solution, a flat socket cavity seeding wheel, comprising a wheel body 1, a round head double flat hole 2, a flat socket cavity 3, and a seed-moving plate guide groove 4. The wheel body 1 is cylindrical, with a diameter of 96 mm and a height of 52 mm. The round head double flat hole 2 is arranged at the center of the wheel body, the flat socket cavity 3 is arranged on the outer circumferential surface of the wheel body, and the seed-moving plate guide groove 4 is arranged on the outer circumferential surface of the wheel body.

[0020] like Figure 4 As shown, the round-headed double flat hole 2 is a mounting hole, which is arranged at the center of the wheel body 1, with a hole long diameter of 15 mm, a distance between the two end faces of the hole of 13 mm, and a hole depth of 52 mm, and is used to place and fix the axle that drives the seed wheel to rotate.

[0021] like Figure 1 As shown, there are four flat socket cavities 3 with the same size, which are arranged in two rows in parallel and can discharge two seeds at the same time. The shape is a combination of a semi-cylindrical and a wedge-like shape. The semi-cylindrical and the wedge-like shape have a rectangular contact surface. Two flat socket cavities 3 in each row are symmetrically distributed around the center line of the wheel body 1.

[0022] like Figure 2 , Figure 3 As shown, the flat socket cavity 3 can accommodate a rectangular parallelepiped in the shape of a corn seed in a flat state, with a length equal to the maximum length of the corn seed plus 1.5 mm, a height equal to the maximum thickness of the corn seed plus 1.5 mm, and a width equal to the maximum width of the corn seed plus 3 mm. The intersection point P of the length and height of the rectangular parallelepiped is on the outer circumference of the seed wheel. There is sufficient seed filling space above and on the sides of the seed in the cavity. Although the seed filling window is enlarged, each cavity can only accommodate a single corn seed, which is conducive to seed filling but not easy to cause reseeding.

[0023] like Figure 1 As shown, there are two seed-pickling plate guide grooves 4, which are arranged on the outer circumferential surface of the wheel body 1 and are distributed in a circular shape through the middle position of each row of flat socket cavities 3. The seed-pickling plate guide grooves 4 penetrate 1 to 2 mm into the bottom of the flat socket cavities 3. The seed-pickling plate guide grooves are used to locate and constrain the working position of the seed-pickling plate.

[0024] The flat socket cavity seed wheel is made of engineering plastic or carbon steel profile, which reduces the friction coefficient between the outer circumferential surface of the seed wheel and the corn seeds, which is conducive to seed filling.

[0025] The working principle and use process of the utility model are as follows: the flat socket cavity is designed according to the principle of corn seed profiling. During sowing operation, the seed wheel rotates clockwise, and the flat socket cavity also rotates accordingly. The corn seed enters the flat socket cavity in a flat state. After the flat socket cavity accommodates a single corn seed in a rectangular shape, there is still sufficient seed filling space above and on the sides. Although the seed filling window is enlarged, each flat socket cavity can only accommodate a single corn seed, which is conducive to seed filling but not easy to cause reseeding.

[0026] This specification uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, according to the idea of ​​the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
