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

[0002] Feed screening is the process of classifying and screening feed raw materials, semi-finished products and finished products according to factors such as particle size, shape, density, etc. The purpose of this process is to improve the quality, utilization rate and safety of feed, meet different feeding needs and reduce feeding costs.

[0003] The Chinese patent document with authorization announcement number CN218424066U proposes a feed screening device, including two side plates, a screening net is fixedly installed between the two side plates, the screening net is inclined, and the mesh holes of the screening net are designed to increase sequentially from top to bottom. A number of dividing mechanisms are detachably installed below the two side plates, and the number of dividing mechanisms include a feed discharge plate. The number of feed discharge plates are arranged below the two side plates, and plugs are fixedly installed on the top of the number of feed discharge plates.

[0004] In the above application, although the feed particles rolling down from the screening net can be sequentially dropped from the meshes of corresponding specifications, thereby realizing filtering of particles of different specifications on the same filter net, the device does not have a dispersing mechanism during feeding, and can only feed a large amount at one time, which may cause feed accumulation or blockage of the screen. Utility Model Content

[0005] In view of the problems existing in the background technology, a screening device is proposed.

[0006] The utility model provides a screening device, comprising a machine body. A frame is arranged below the machine body, and a feed inlet and a vibration mechanism are arranged at the upper end; the machine body and the frame are connected by a spring. A plurality of sieve plates are arranged in the machine body. A feeding assembly is arranged between the feed inlet and the plurality of sieve plates to evenly disperse the feed. And a feeding assembly is arranged between the plurality of sieve plates and the feeding assembly to make the feed drop at intervals.

[0007] Preferably, the material discharge assembly includes a material discharge box arranged below the feed port and above the multiple screen plates; the upper end of the material discharge box is open, and multiple material discharge ports are opened on the side wall; both ends are provided with rotating shafts, and are rotatably connected to the inner wall of the machine body through the rotating shafts; gears are connected to the two rotating shafts; the upper ends of the gears are meshed and connected to racks; the racks are slidably connected to the slide rails arranged at the top of the machine body; a telescopic mechanism is also provided on the inner wall of the machine body; the telescopic end of the telescopic mechanism is connected to the rack.

[0008] Preferably, the feeding assembly includes transmission cylinders that are symmetrically arranged at the upper opening of the discharge box and are connected to each other; multiple discharge ports are opened on one side of the two transmission cylinders, the upper ends of the two transmission cylinders have a common opening, and connecting columns are provided on the side walls, and are connected to the inner wall of the machine body through the connecting columns.

[0009] Preferably, the upper openings of the two transmission cylinders are connected with a feed hopper; the upper outer wall of the feed hopper is seamlessly fitted with the inner wall of the feed port.

[0010] Preferably, the opposite ends of the two transmission cylinders are both arranged to be tilted downward.

[0011] Preferably, a plurality of feed openings 1 are equidistantly arranged on the feed box; and a plurality of feed openings 2 are equidistantly arranged on the two transmission cylinders.

[0012] Preferably, the plurality of feed openings 1 and the plurality of feed openings 2 are arranged one by one opposite to each other.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] (1) The screening equipment starts the telescopic mechanism to drive the rack to slide back and forth along the slide rail, thereby driving the gear, the rotating shaft and the feed box to rotate back and forth. The feed is dropped at intervals to prevent the feed from piling up or clogging the sieve holes of the sieve plate due to excessive feed being dropped at one time, thereby improving the screening efficiency. At the same time, it can reduce the impact and wear of the feed on the sieve plate and extend the service life of the sieve plate.

[0015] (2) The screening equipment pours the feed into the machine body from the feed inlet, allowing the feed to fall into the transmission cylinder along the feed hopper, then slide along the transmission cylinder to both sides, and finally fall into the discharge box along multiple discharge ports. When the feed is discharged, the feed can be evenly dispersed on the screen plate, so that the feed particles can better contact the sieve holes on the screen plate, thereby achieving more accurate screening and ensuring that the particle size of the screened feed meets the requirements. In addition, it can also avoid feed accumulation and clogging of the sieve holes, thereby improving the screening efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-3 As shown, a screening device proposed by the utility model includes a machine body 1, a plurality of sieve plates 6, a feeding assembly 8 and a feeding assembly 7. A frame 2 is provided below the machine body 1, and a feed inlet 4 and a vibration mechanism 5 are provided at the upper end. The vibration mechanism 5 is a vibration motor; the machine body 1 and the frame 2 are connected by a spring 3. A plurality of sieve plates 6 are arranged in the machine body 1. The feeding assembly 8 is arranged between the feed inlet 4 and the plurality of sieve plates 6 to evenly disperse the feed. The feeding assembly 7 is arranged between the plurality of sieve plates 6 and the feeding assembly 8 to allow the feed to fall at intervals.

[0021] Further explanation, the feeding assembly 7 includes a feeding box 71 arranged below the feed port 4 and above the plurality of sieve plates 6; the upper end of the feeding box 71 is open, and a plurality of feeding ports 73 are provided on the side wall, and a rotating shaft 72 is provided at both ends, and is rotatably connected to the inner wall of the body 1 through the rotating shaft 72; gears 74 are connected to the two rotating shafts 72; the upper ends of the gears 74 are meshed and connected with racks 75; the racks 75 are slidably connected with the slide rails 76 arranged at the top of the body 1; a telescopic mechanism 77 is also provided at the inner wall of the body 1, and the telescopic mechanism 77 is a cylinder; the telescopic end of the telescopic mechanism 77 is connected to the rack 75. The feed is allowed to fall at intervals to prevent excessive feeding at one time from causing feed accumulation or blocking the sieve holes of the sieve plate 6, thereby improving the screening efficiency. At the same time, it can reduce the impact and wear of the feed on the sieve plate 6, and extend the service life of the sieve plate 6.

[0022] Further explanation, the feeding assembly 8 includes transmission cylinders 81 symmetrically arranged at the upper opening of the feeding box 71 and connected to each other; a plurality of feeding ports 83 are opened on one side of the two transmission cylinders 81, the upper ends of the two transmission cylinders 81 are open together, and the side walls are provided with connecting columns 82, and are connected to the inner wall of the body 1 through the connecting columns 82. Feeds put in from the feed port 4 can be transferred into the feeding box 71.

[0023] Further explanation, the upper openings of the two transmission cylinders 81 are connected with a feeding hopper 84; the upper outer wall of the feeding hopper 84 is seamlessly fitted with the inner wall of the feed inlet 4. The feed fed from the feed inlet 4 can all fall into the transmission cylinder 81 and then fall into the feeding box 71. This prevents the feed from falling onto the screen plate 6 first, thereby rendering the feeding assembly 7 ineffective.

[0024] Further, the opposite ends of the two transmission cylinders 81 are tilted downward, so that the feed can slide down the transmission cylinders 81 to both sides, and then fall into the feed box 71 from the plurality of feed openings 83, thereby dispersing the feed.

[0025] Further explanation, multiple feed openings 1 73 are equidistantly arranged on the feed box 71; multiple feed openings 2 83 are equidistantly arranged on the two transmission cylinders 81. Multiple feed openings 1 73 are opposite to multiple feed openings 2 83. When feeding, the feed can be evenly dispersed on the sieve plate 6, so that the feed particles can better contact the sieve holes on the sieve plate 6, thereby achieving more accurate screening and ensuring that the particle size of the feed under the sieve meets the requirements. In addition, it can also avoid feed accumulation and clogging of the sieve holes, thereby improving the screening efficiency.

[0026] The working principle of the utility model is as follows: when working, first start the vibration mechanism 5 to drive the machine body 1 and multiple sieve plates 6 to vibrate along the spring 3, then pour the feed from the feed port 4 into the machine body 1, so that the feed falls into the transmission cylinder 81 along the feed hopper 84, then slides to both sides along the transmission cylinder 81, and finally falls into the discharge box 71 along multiple discharge ports 2 83. Then start the telescopic mechanism 77 to drive the rack 75 to slide back and forth along the slide rail 76, thereby driving the gear 74, the rotating shaft 72 and the discharge box 71 to rotate back and forth. When the discharge box 71 rotates to the discharge port 1 73 facing downward, the feed will fall evenly onto the sieve plate 6 along the multiple discharge ports 1 73; when the discharge box 71 rotates to the discharge port 1 73 facing upward, the feed will no longer fall. Through the above process, the feed falls at intervals and is evenly dispersed on the sieve plate 6, so as to avoid feed accumulation and clogging of the sieve holes of the sieve plate 6, thereby improving the screening efficiency.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
