Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a grain unloading screen device used for feed processing. Background Art

[0002] Grain is an important raw material required by the feed processing industry. Since there are many impurities such as husks and sand in grain, when unloading grain into the silo, it is necessary to use a screen at the grain unloading port to screen out the debris in the grain. The screen is set obliquely, and the debris is screened out from the bottom of the screen, and the grain enters the silo along the inclined surface of the screen. However, the screen currently used has the problem of easy clogging and needs to be cleaned frequently, which affects the use effect. In order to improve the use effect, a double-layer screen has appeared. An elastic ball made of rubber or other materials is placed in the center. When unloading grain, the mesh holes are reciprocated by the elastic ball to avoid clogging. However, the following problems still exist during use: the screen is set obliquely to prevent the elastic ball from sliding into the lower side, and several spaces are isolated on the inside of the screen through partitions. Several elastic balls are placed in each space. Although the clogging problem is solved to a certain extent, the existence of the partition itself occupies the space of the screen, thereby affecting the filtration efficiency; to ensure the best effect of the elastic ball, the elastic ball needs to be cleaned or replaced regularly. At present, the elastic ball is not only inconvenient to replace, but also manually cleaning one by one is cumbersome.

[0003] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a grain unloading screen device for feed processing which can effectively avoid blockage.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows: the utility model provides a feed unloading screen device for feed processing, comprising a rectangular frame, wherein two mutually parallel screens are respectively arranged on the upper and lower sides of the rectangular frame, and a plurality of movable elastic balls are arranged between the two screens;

[0006] A mounting frame is fixedly connected to the right side of the rectangular frame, and a striking component cooperating with the elastic ball is arranged inside the mounting frame. A mounting box is fixedly connected to the left side of the rectangular frame, and a cleaning component cooperating with the elastic ball is arranged inside the mounting box. A linkage component is arranged between the striking component and the cleaning component.

[0007] The top of the rectangular frame is provided with enclosures on both sides, front and rear, and on the left side;

[0008] A through slot is formed in the right center of the rectangular frame, and the through slot is connected to the installation frame;

[0009] The striking component comprises an impact plate slidably connected to the inner side of the through slot, a lower ridge is provided at the bottom of the impact plate, and a plurality of springs are fixedly connected between the side of the impact plate away from the rectangular frame and the right inner wall of the installation frame;

[0010] A rotating rod is provided on the lower side of the impact plate and is horizontally rotatably connected to the inner side of the mounting frame. An upper ridge that matches the lower ridge is provided on the outer wall of the rotating rod along its axial direction. One end of the rotating rod is coaxially fixedly connected to the output end of the driving motor.

[0011] The impact plate is located at the inner end of the rectangular frame and has an arc-shaped structure;

[0012] Limiting plates matched with the outer wall of the rectangular frame are symmetrically arranged on both sides of the impact plate.

[0013] The cleaning component includes two roller brushes symmetrically arranged on the inner side of the installation box and a fan arranged on one side wall of the installation box. The bottom of the installation box is a mesh structure, and the top of the installation box is hinged with a cover plate.

[0014] The central rotating shafts of the two rolling brushes on one side away from the fan extend to the outside of the installation box and are both coaxially sleeved with gears, and the two gears are meshed with each other.

[0015] The two ends of the rotating rod extend to the outside of the installation frame respectively, and the linkage component includes a first transmission plate and a second transmission plate coaxially sleeved on two sides of the rotating rod respectively;

[0016] A third transmission disc is coaxially sleeved on the outer side of the central rotating shaft of one of the roller brushes, and a first transmission belt is sleeved between the third transmission disc and the first transmission disc;

[0017] A fourth transmission disc is coaxially sleeved on the outer side of the central rotating shaft of the fan, and a second transmission belt is sleeved between the fourth transmission disc and the second transmission disc.

[0018] A through taking hole is provided on the rear side wall of the rectangular frame, and a sliding door is slidably matched inside the taking hole.

[0019] When the utility model is actually used: when unloading grain, the elastic ball will gradually move to the side of the lower striking component due to gravity, the driving motor drives the rotating rod to rotate, the lower ridge pushes the upper ridge so that the impact plate compresses the spring, and after the lower ridge is separated from the upper ridge, under the action of the spring, the impact plate accelerates the impact of the elastic ball to make it roll back to the upper side, and several elastic balls are hit by the impact plate alternately, so as to achieve the effect of uniform distribution of the elastic balls to avoid clogging of the screen. At the same time, the elastic balls that have been used and need to be cleaned are taken out through the taking hole and put into the inside of the installation box. When the driving motor rotates, the two roller brushes are driven to rotate in opposite directions through the linkage component to clean the surface of the elastic ball, and at the same time, the fan is driven to rotate to blow air to the inside of the installation box, so that the debris is cleaned and leaks out from the mesh at the bottom of the installation box. The screen device can also be used in conjunction with a vibration device, and an additional power device is added to achieve a better screening effect.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model avoids setting a plurality of fixed frames on the inner side of the double-layer screen to limit the elastic ball, thereby solving the problem of the fixed frames causing a certain blockage to the screen;

[0022] 2. The utility model continuously strikes the elastic balls that slide down the lower side through the striking component, so that they return to the upper side, thereby achieving uniform distribution of the elastic balls and increasing the screening effect;

[0023] 3. The utility model can automatically clean the elastic balls that need to be cleaned through the cleaning components, avoiding the tedious process of manual cleaning;

[0024] 4. The utility model has a novel and ingenious structural design. The cleaning components can be linked by the operation of the striking components. No additional power device is required, and the economy is better. BRIEF DESCRIPTION OF THE DRAWINGS
