[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 3-6 The present invention provides a cylindrical primary cleaning sieve for wheat screening, comprising: Main components: The main components include mounting platform 11, fixing frame 12, screen cylinder 13 and feeding hopper 14; The fixing frame 12 is fixedly connected to the top of the mounting platform 11, the screen cylinder 13 is fixedly connected to the top of the fixing frame 12, and the feeding hopper 14 is fixedly connected to the rear end of the screen cylinder 13. The main components also include a motor 15 and a feeding port 16; The motor 15 is installed at one end of the screen cylinder 13, and the discharge port 16 is installed at the bottom end of the screen cylinder 13; Wheat is fed into the screen cylinder 13 through the feed hopper 14. Simultaneously, the motor 15 is started, and the rotating screen cylinder 13 initiates the screening process. The screen cylinder 13 contains a screen mesh. As the material rotates within the screen cylinder 13, smaller particles pass through the screen mesh and fall into the collection chamber below, while larger particles are blocked by the screen mesh and remain inside the screen cylinder 13. Based on the different specifications of the screen cylinder 13, the material is graded into particles of different sizes. Larger particles are collected above the screen mesh, while smaller particles pass through the screen mesh and enter the collection chamber. The smaller particles are discharged through the discharge port 16 of the collection chamber and fall into a set of toothed racks 33, serving as the screening result. Larger particles continue to move within the screen cylinder 13 and are eventually discharged through the large waste discharge port 16 and fall into another set of toothed racks 33. All of the above parts are existing technologies; The feeding assembly includes a feeding box 21, a feeding bin 22, a hydraulic rod 23, and a guide rail 24; The feeding box 21 is fixedly connected to the top of the feeding bin 14, the feeding bin 22 is fixedly connected to the top of the feeding box 21, the hydraulic rod 23 is fixedly connected to the rear end of the feeding box 21, and the guide rail 24 is fixedly connected to the inner wall of the feeding box 21. The feeding assembly also includes a feeding plate 25, an auxiliary plate 26, and a storage bin 27; The auxiliary plate 26 is fixedly connected to one end of the hydraulic rod 23, the storage box 27 is fixedly connected to the bottom end of the auxiliary plate 26, and the feeding plate 25 is rotatably connected to the bottom end of the storage box 27. The feeding bin 22 provides space for adding wheat, the guide rail 24 provides space for guiding the sliding of the auxiliary plate 26, and the top of the feeding bin 14 and the bottom front of the feeding box 21 penetrate each other. With the auxiliary cooperation between the feeding box 21 and the hydraulic rod 23, the hydraulic rod 23 can drive the auxiliary plate 26 to slide repeatedly inside the guide rail 24, so that the auxiliary plate 26 and the feeding bin 22 are repeatedly misaligned, and the feeding plate 25 is repeatedly flipped. Working principle: When the worker adds wheat; First, by pouring wheat into the inside of the feeding bin 22, the wheat can be collected into the inside of the storage box 27 through the auxiliary plate 26. At the same time, by activating the hydraulic rod 23, the auxiliary plate 26 is driven to slide repeatedly inside the guide rail 24, so that the top center of the auxiliary plate 26 and the bottom of the feeding bin 22 are repeatedly misaligned. Next, as the storage box 27 slides repeatedly to the point above the feeding bin 14, the feeding plate 25 installed at the bottom of the storage box 27 can be repeatedly de-attached to the feeding box 21. The feeding plate 25 can be repeatedly opened and closed as the storage box 27 slides repeatedly, allowing the wheat collected in the storage box 27 to be discharged as the storage box 27 moves forward. As the storage box 27 moves backward, the auxiliary plate 26 is aligned with the bottom of the feeding bin 22 again, thereby replenishing the storage box 27. This step helps workers to evenly distribute wheat while achieving automatic feeding.
[0017] Please see Figure 2-5 As shown, this embodiment, based on the above embodiment, also includes a collection component; The collection components include a slide rail 31, a placement box 32, a rotating gear 34, and a threaded rod 35; The slide rail 31 is fixedly connected to the top of the mounting platform 11, the placement box 32 is slidably connected to the inside of the slide rail 31, the rotating gear 34 is rotatably connected to the inner bottom wall of the placement box 32, and the threaded rod 35 is fixedly connected to the top of the rotating gear 34.
[0018] The collection assembly also includes a rack 33, a through groove 36, a screw plate 37, and a collection box 38; The rack 33 is fixedly connected to the inner front end of the slide rail 31, the through groove 36 is opened on both sides of the outer wall of the placement box 32, the screw plate 37 is threadedly connected to the top of the threaded rod 35, and the collection box 38 is placed on the top of the screw plate 37. The slide rail 31 is fixedly connected to the top of the mounting platform 11 and provides sliding space for the placement box 32. The placement box 32 is used to open the through groove 36 and to provide lifting space for the collection box 38. The bottom ends of the screw plate 37 and the threaded rod 35 are set on the same central axis. The rotating gear 34 and the rack 33 are set on the same central axis. With the auxiliary cooperation between rack 33 and rotating gear 34, the collection box 38 can be driven to rise vertically while the placement box 32 is pulled outward. Working principle: When workers handle the sieved wheat; First, by pulling out the placement box 32 inside the slide rail 31, the rack 33 installed at the front end of the slide rail 31 can slide and rotate with the placement box 32 to engage with the gear 34. Next, the rotating gear 34 can be rotated to drive the threaded rod 35 to rotate, and the screw plate 37 can be raised vertically along the threaded trajectory outside the threaded rod 35. The collection box 38 placed on the top of the screw plate 37 can be lifted, making it convenient for staff to pick up the rack 33. This step helps staff to easily retrieve the collection bin 38 containing wheat.
