Description

Technical Field

[0001] The utility model relates to the technical field of seed screening equipment, in particular to a breeding screening device. Background Art

[0002] In breeding and cultivation work, in order to improve seed quality, the seeds need to be screened to remove debris and smaller seeds. At present, the screening of small batches of seeds is mostly achieved by screen vibration, which has a large working noise and causes rapid wear of parts. At the same time, there is the problem of misscreening of seeds due to vibration, resulting in waste. In addition, during the discharge process, vibration is required to be combined with screen tilting, and the processing efficiency is relatively slow. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a breeding screening device in view of the above-mentioned technical deficiencies. The frame drives the screen plate to swing left and right to realize the seed screening operation, effectively reducing the generation of noise during the operation, and after the screening is completed, the seeds can be quickly poured out by directly flipping the screen plate, thereby improving the discharge efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model includes:

[0005] The chassis is divided into two left and right cavities. A slidingly connected frame is provided inside the right cavity, a flippable screen plate is provided inside the frame, a driving member connected to the frame is provided in the left cavity, and a thrust member for flipping the screen plate is provided above the chassis.

[0006] Preferably, slideways are symmetrically arranged in the right cavity; and support plates connected to the slideways are symmetrically arranged on the frame.

[0007] Preferably, the driving member includes a motor and a connecting rod; the motor is installed in the left cavity, and a rotating wheel is provided on the motor; and both ends of the connecting rod are respectively connected to the rotating wheel and the frame.

[0008] Preferably, a support shaft connected to the sieve plate is provided in the middle of the frame.

[0009] Preferably, the thrust member comprises a hydraulic cylinder and a driven rod; the hydraulic cylinder is installed above the chassis, and a push rod is provided on the hydraulic cylinder; one end of the driven rod is slidably connected to the screen plate, and the other end is connected to the push rod via a rotating shaft.

[0010] Preferably, a polished rod connected to the driven rod is provided on one side of the sieve plate.

[0011] Preferably, two transverse plates are symmetrically provided at the lower end of the driven rod, and magnetic suction parts are provided at equal intervals along the length direction of the transverse plates.

[0012] Preferably, an extension column is provided below the magnetic attraction member.

[0013] Preferably, a discharge plate is provided on the chassis below the right cavity.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The drive member drives the frame and the screen plate to move back and forth horizontally, which can effectively realize the seed screening operation. The screening form of reciprocating movement avoids the generation of vibration and noise, reduces the wear of parts, and works more stably. After screening, the screen plate can be turned over to quickly complete the discharge of seeds, thereby improving the overall processing efficiency.

[0016] 2. The thrust piece will not affect the normal displacement movement of the frame while completing the flipping action of the screen plate. The overall structure is compact and the design is ingenious. At the same time, the thrust piece also plays a role in leveling and positioning the screen plate during the screening process;

[0017] 3. The screened debris and unqualified seeds can be guided to one side of the chassis by the discharge plate for easy collection and cleaning;

[0018] 4. During the seed screening process, the magnetic suction parts on the horizontal plate can use magnetic force to perform secondary adsorption of iron debris, ensuring the quality of seeds after screening and avoiding the presence of metal debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When in use, the seeds to be screened are poured into the space formed by the frame 2 and the sieve plate 3, and then the driving member 4 is started. The driving member 4 reciprocates and drives the frame 2 and the sieve plate 3 to move horizontally. During the displacement process, smaller objects and debris fall from the pores in the sieve plate 3 to achieve screening. After the screening is completed, the thrust member 5 pulls one side of the sieve plate 3 to move upward, thereby turning the sieve plate 3 over and quickly discharging the seeds. For small batch seed screening operations, the seed discharging efficiency is effectively accelerated, thereby improving the overall work efficiency. In addition, during the overall screening process, the vibration is effectively reduced, the wear of components is reduced, the service life of the structure is increased, and the noise is avoided.
