Description
Technical Field
[0001] This utility model relates to the technical field of seed screening, and in particular to a seed screening device for garden plant breeding. Background Technology
[0002] A seed screening device for garden plant breeding is a specially designed device for efficient and precise screening of seeds during the garden plant breeding process. In order to ensure the quality of seeds, it is necessary to screen the seeds to remove impurities and unqualified seeds.
[0003] The existing Chinese utility model patent with application number CN202420160841.8 relates to a seed sieve, which includes a sieve shell, a sieve motor, a central column, a limiting groove, a sieve frame, a convex ring, a mounting block, and a sieve cylinder, etc. It can remove seeds while cleaning the sieve screen to prevent impurities from clogging the sieve holes.
[0004] However, the above-mentioned device has a slow screening speed and a complicated seed feeding and retrieval process in actual use, making it unsuitable for large-scale seed screening. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a seed screening device for garden plant breeding. The seed feeding device quickly blows the seeds to be screened onto the screening device, and the screening device performs the screening operation. The screening device can quickly switch between screening screens with different aperture sizes, so that the equipment can screen seeds of different particle sizes in batches. The screened seeds are transported by a conveying device, which improves the practicality of the device.
[0006] This utility model discloses a seed screening device for garden plant breeding; it includes a seed feeding device, a screening device, and a conveying device. The screening device is installed on the seed feeding device, and the conveying device is also installed on the seed feeding device. The seed feeding device quickly blows the seeds to be screened onto the screening device, and the screening device performs the screening operation. The screening device quickly switches between screening screens of different aperture sizes, so that the equipment can screen seeds of different particle sizes in batches. The conveying device transports the screened seeds, improving the practicality of the device.
[0007] Preferably, the seed feeding device includes a screening box, an electric cylinder, a pusher plate, a support plate, a blower, and a variable diameter inlet. A feeding port is located on the upper left side of the screening box. An electric cylinder is installed on the upper part of the left side of the screening box, with its moving end extending through the left side of the screening box into the interior. A pusher plate is connected to the moving end of the electric cylinder. A support plate is installed on the upper part of the screening box. A strip-shaped air inlet is located on the lower right side of the screening box, with a variable diameter inlet connected to it. A blower is installed on the input end of the variable diameter inlet. Seeds are poured from the feeding port of the screening box onto the support plate inside the screening box. Then, the electric cylinder is slowly extended, pushing the seeds slowly to the lower part of the screening box. Simultaneously, the blower is turned on to pressurize outside air and send it into the screening box, blowing the fallen seeds towards the screening device for sieving. The strip-shaped air inlet inside the screening box increases the effective blowing area, preventing seeds from remaining in the bottom edges and corners of the screening box, thus improving the practicality of the device.
[0008] Preferably, it also includes a rubber plate, which is installed on the lower end surface of the pusher plate; by installing the rubber plate on the lower end surface of the pusher plate, the lower end surface of the pusher plate is prevented from directly contacting the upper end surface of the support plate and crushing the seeds when the electric cylinder extends and pushes, thereby improving the protection and practicality of the device.
[0009] Preferably, the screening device includes a support frame, a geared motor, a lead screw, a switching frame, connecting rods, a screen frame, an arc plate, and a sliding guide groove. An arc plate is located on the left side of the screening box, with slotted holes at the top and bottom of its center. The support frame is mounted on the left side of the front face of the screening box, and a geared motor is mounted on the front face of the support frame. A lead screw is installed between the front of the support frame and the screening box, and the output end of the geared motor is connected to the lead screw. The front of the switching frame is connected to the lead screw via a nut. The rear of the switching frame extends through the slotted holes in the screening box and the arc plate to the rear side of the screening box. The front and rear of the switching frame are connected by four sets of connecting rods. Slots are provided on opposite sides of the two sets of connecting rods, allowing the screen frame to be inserted into the slots of the connecting rods. The length of the connecting rods... The screen is twice the width of the screening box. Two adjacent sets of screen frames are placed in the slot. The inner side of the slotted hole of the arc plate is provided with a sliding guide groove, in which the connecting rod slides. The screen frames work with the seed feeding device to screen the seeds. The sliding guide groove limits the forward and backward movement of the connecting rod. The slot on the connecting rod allows the operator to quickly change the screen frames. The screen frames screen the seeds. By turning on the geared motor, the power is transmitted to the lead screw, which drives the lead screw to rotate, thereby moving the switching frame forward and backward to feed different types of screen frames into the screening box for screening. This allows the equipment to quickly screen seeds of different diameters. The arc structure of the arc plate itself facilitates the cooperation with the carrying plate to make the seeds circulate and rotate in the screening box.
[0010] Preferably, it also includes a rotating shaft and a rubber baffle. The rotating shaft is installed on the lower right end face of the bearing plate, and the rubber baffle is connected to the side of the rotating shaft. The rubber baffle intercepts the seeds that are turned over by the upper part of the arc plate, reducing the circumference of the seeds turning over in the screening box, thereby increasing the contact time between the seeds and the surface of the screen frame, improving the screening efficiency and practicality of the equipment.
[0011] Preferably, the conveying device includes conveyor rollers and a conveyor belt. A support is installed at the bottom of the screening box, and a discharge end is provided on the left side of the lower end face of the screening box. Multiple sets of conveyor rollers are horizontally installed on the support at the bottom of the screening box, and the conveyor belt is fitted onto the multiple sets of conveyor rollers. A motor is connected to the outermost conveyor roller. When the motor is turned on, power is transmitted to the conveyor rollers. The seeds screened out are transported by the multiple sets of conveyor rollers in conjunction with the conveyor belt, which reduces the labor intensity of the operators and improves the practicality of the device.
[0012] Preferably, the device also includes a partition and a discharge hopper. A partition is provided on the left side of the screening box, and a discharge hopper is provided on the bottom discharge end of the screening box. The seeds screened out are collected and discharged through the discharge hopper to prevent the seeds from falling out of the conveyor belt's carrying capacity with the airflow, thus improving the practicality of the device.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the seed feeding device quickly blows the seeds to be screened onto the screening device, and the screening operation is carried out in conjunction with the screening device. The screening device quickly switches between screening screens with different apertures, so that the equipment can screen seeds of different particle sizes in batches. The screened seeds are transported by the conveying device, which improves the practicality of the device. Attached Figure Description
