Technical Field

[0001] The utility model belongs to the field of agricultural seed screening, and specifically relates to an agricultural seed screening device for agricultural economy. Background Technique

[0002] A seed is a structure formed after the ovule of a seed plant is fertilized, and generally consists of a seed coat, an embryo, and an endosperm, etc. A seed is a unique reproductive body of gymnosperms and angiosperms. It is formed by the ovule after pollination and fertilization. A seed generally consists of a seed coat, an embryo, and an endosperm. Some plants have mature seeds with only two parts, the seed coat and the embryo.

[0003] In a Chinese utility model patent with the publication number CN218340272U, an agricultural seed screening device is disclosed, including: a screening box, support legs are fixed around the bottom of the screening box, the top of the screening box is open, and a material receiving port is opened at the bottom of the screening box; inclined sliding grooves are provided on both side walls of the screening box; first sliding ports are inclined and opened on both side walls of the screening box above the corresponding sliding grooves. In this utility model, the seeds to be screened are slowly poured into the screening box in batches from the inclined top of the sieve mesh. When the seeds freely slide to the bottom of the sieve mesh, some small-sized seeds that do not meet the requirements fall from the material receiving port.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: When using this agricultural seed screening device, it is necessary to manually move the push rod to drive the material pushing plate to move, so as to achieve the effect of screening seeds. The operation is not convenient and labor-saving enough, and the working efficiency of the seed screening work is not high.

[0005] Therefore, those skilled in the art have proposed an agricultural seed screening device for agricultural economy to solve the problems raised in the background technique. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides an agricultural seed screening device for agricultural economy, so as to solve the problem that when using the existing agricultural seed screening device, it is necessary to manually move the push rod to drive the material pushing plate to move, so as to achieve the effect of screening seeds. The operation is not convenient and labor-saving enough, and the working efficiency of the seed screening work is not high.

Two symmetrically arranged rollers are rotatably connected to both side surfaces of the limiting frame, and the rollers are located inside the sliding grooves. The sieve frame includes a sieve mesh fixedly connected thereto.

The turntable drives the second limiting column to rotate on it, thereby driving the rotating rod to move, and then pushing the limiting frame to move. The rollers on the limiting frame roll in the sliding grooves. Through the above steps, the limiting frame and the sieve frame inside it can be driven to move back and forth, so as to achieve the effect of screening seeds.

By controlling the upward movement of the output end of the cylinder, the plug board can be moved out of the triangular block. Then, a packaging bag can be used to catch the seeds below the blanking frame. The vibrating motor can drive the rotating plate to vibrate on the spring, which can accelerate the blanking speed of the blanking frame.
