Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed production, and more specifically, to a screening device for seed production. Background Technology
[0002] Agricultural sowing requires a large quantity of high-quality seeds, but many seeds are not fully developed and contain impurities. These imperfections can damage the sowing machine during the sowing process and reduce yield. Therefore, a screening device is needed to select the seeds.
[0003] In existing seed screening devices, the sieves are usually fixed in place, which means that the device can only screen seeds of the same size. When screening seeds of different sizes, multiple devices are required, which is very troublesome. Furthermore, when using existing screening devices, seeds of different sizes and shapes, as well as those containing impurities and soil, are prone to getting stuck or accumulating when passing through the sieve, causing the sieve pores to become clogged, which in turn affects the screening effect and efficiency.
[0004] Therefore, we have made improvements to this and proposed a screening device for seed production. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a screening device for seed production, which solves the problems mentioned in the background art.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] A screening device for seed production is proposed to solve the above problems.
[0008] The application is as follows:
[0009] The device includes a housing, on one side of which a feed pipe is fixedly installed, and at the upper end of the feed pipe a feed hopper is fixedly installed. Fixing rings are fixedly installed on both inner walls of the housing, and both fixing rings are inclined. A rotating cylinder is rotatably connected to one side of each of the two fixing rings, and a screen cylinder is positioned between the two rotating cylinders. A rotating mechanism is fixedly installed between one rotating cylinder and the inner wall of the housing, and a connecting mechanism is provided between the rotating cylinder and the screen cylinder. A cleaning mechanism is provided on the top of the housing, and a discharge hopper is fixedly installed on the lower surface of the housing. A rotating door is rotatably connected to the front surface of the housing.
[0010] The rotating mechanism includes a gear ring, which is fixedly installed on the outer surface of a rotating cylinder on one side. A rotating rod is rotatably connected to the inner wall of one side of the housing, and the rotating rod is inclined. A gear is fixedly installed on the outer surface of one side of the rotating rod, and the gear meshes with the gear ring.
[0011] The connecting mechanism includes slots and blocks, and there are several slots and blocks. Several slots are evenly opened on both sides of the screen cylinder, and several blocks are evenly connected to one side of the rotating cylinder. The blocks are engaged with the slots, and the screen cylinder and the rotating cylinders on both sides form an engaging structure.
[0012] The rotating cylinder has several grooves on one side surface, and several locking blocks are evenly distributed in the grooves and slidably connected. A first spring is fixedly installed between one side surface of the locking block and the inner wall of the groove.
[0013] The upper surface of the slide groove is provided with a connecting groove, and a connecting block is slidably connected inside the connecting groove. The connecting block is fixedly connected to the locking block, and a sliding ring is fixedly installed on the upper surface of several connecting blocks.
[0014] As a preferred technical solution of this application, an inclined fixing plate is fixedly installed on one side surface of the box, and a drive motor is fixedly installed on the upper surface of the fixing plate. The output end of the drive motor is fixedly connected to the rotating rod.
[0015] As a preferred technical solution of this application, the cleaning mechanism includes a fixing block, which is obliquely and fixedly installed on the top of the box. A slider is slidably connected to the lower surface of the fixing block, and a cleaning brush is fixedly installed on the lower surface of the slider.
[0016] As a preferred technical solution of this application, the fixed block has a cavity inside, and a baffle is slidably connected inside the cavity. The baffle is fixedly connected to the slider, and a second spring is fixedly installed between the baffle and the inner wall of the cavity.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In the scheme of this application:
[0019] 1. Through the use of the connecting mechanism, the slots are evenly distributed on both sides of the screen cylinder, while the locking blocks are installed on one side of the rotating cylinder. The two are tightly connected by a locking mechanism, forming a connection structure that is both easy to disassemble and sturdy and durable. This simplifies the screen cylinder replacement process, allowing users to easily replace screen cylinders of different specifications according to their screening needs. It also ensures the stability of the screen cylinder and the screening effect during rotation, thereby greatly improving the flexibility and efficiency of screening operations.
[0020] 2. Through the use of the cleaning mechanism, the slider moves in the cavity, while the cleaning brush closely adheres to the outer wall of the screen cylinder. The internal second spring can hold the baffle and slider together. When the screen cylinder rotates, it can effectively scrape away impurities, soil and fine seed particles inside the screen holes, ensuring the screen holes are unobstructed and avoiding blockage.
