Description

Technical Field

[0001] The utility model belongs to the technical field of feed production, and particularly relates to a screening device for feed production. Background Art

[0002] In the process of feed production, the purity of raw materials is crucial for the normal operation of production equipment. High-speed rotating feed pelletizers and crushers are particularly vulnerable to impurities such as iron nails, bolts, nuts, and small iron blocks mixed in feed raw materials. These impurities can not only cause the sieve bottom of the equipment to be punctured, but also damage the die and burn out the motor, bringing serious safety hazards and economic losses.

[0003] To solve this problem, the commonly used treatment method is to use a magnetic separator. The magnetic separator is one of the most widely used and highly versatile devices in the industry, suitable for separating substances with magnetic differences. However, the traditional magnetic separator has a major defect in use, that is, it cannot stir the feed raw materials inside the feed hopper, thus easily causing blockage and affecting work efficiency. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model provides a screening device for feed production, and the screening efficiency of the device is high.

[0005] A screening device for feed production according to an embodiment of the first aspect of the utility model includes a material selection frame. A plurality of blanking grooves are formed in the frame body of the material selection frame along the length direction, and a flip-up baffle is installed at each blanking groove; a conveying component is arranged below the blanking groove, and an electromagnetic generator is arranged inside the conveying component; a vibration component is arranged below the material selection frame, and the material selection frame reciprocates through the vibration component; a scraping component that can move along the length direction of the material selection frame is further arranged inside the material selection frame.

[0006] A screening device for feed production according to an embodiment of the utility model has at least the following beneficial effects:

[0007] By arranging the vibration component to make the material selection frame reciprocate, the feed raw materials can be effectively vibrated and evenly distributed in the material selection frame. Then, the opening and closing of the blanking groove are controlled by the opening and closing of the baffle, which is convenient for impurities such as iron nails to fall. At the same time, the magnetic field generated by the electromagnetic generator can effectively adsorb magnetic impurities such as iron nails in the feed raw materials, so that these impurities fall from the blanking groove onto the conveying component, ensuring the precise separation of the feed raw materials and improving the feed quality.

[0008] According to some embodiments of the present utility model, one end of the material baffle is hinged to the blanking chute. The blanking chute is opened and closed by the flipping of the material baffle. The flipping of the material baffle is realized through the hinge structure, which can conveniently control the opening and closing of the blanking chute, making the operation more simple. The flipping angle of the material baffle is controllable, and the opening and closing of the blanking chute can be accurately controlled according to actual needs, ensuring the uniform distribution and effective screening of feed raw materials.

[0009] According to some embodiments of the present utility model, it further includes a driving cylinder. A connecting rod is provided at the output end of the driving cylinder. Through the cooperation of the driving cylinder and the connecting rod, the flipping angle and position of the material baffle can be accurately controlled, ensuring the stability and consistency of the screening process.

[0010] According to some embodiments of the present utility model, multiple material baffles are flipped synchronously through the connecting rod. The synchronous flipping of multiple material baffles through the connecting rod can ensure the simultaneous opening and closing of the blanking chute, improving the working efficiency and uniformity of the screening device.

[0011] According to some embodiments of the present utility model, the scraping component includes electric push rods arranged at both ends of the material selection frame. The electric push rods are connected with scraping plates. The scraping plates are controlled by the electric push rods to move along the length direction of the material selection frame, thereby scraping the feed raw materials at both ends of the material selection frame to the middle area, effectively concentrating the raw materials scattered at both ends of the material selection frame, reducing the waste of raw materials, and increasing the utilization rate and economic benefits of the screening device.

[0012] According to some embodiments of the present utility model, the bottom of the scraping plate has an inclination. During the movement process, it can more effectively contact and push the feed raw materials. The inclination design can reduce the resistance between the scraping plate and the feed raw materials during the scraping process, making the movement of the scraping plate smoother. At the same time, it can prevent the feed raw materials from accumulating in front of the scraping plate during the scraping process, ensuring that the raw materials can be smoothly scraped to the middle area and improving the continuity and stability of the screening process.

[0013] According to some embodiments of the present utility model, the vibration component is composed of multiple vibration struts. The multiple vibration struts are respectively installed at the bottom edge of the material selection frame, which can provide a uniform vibration effect, enabling the feed raw materials in the material selection frame to vibrate sufficiently, ensuring the uniformity and high efficiency of the screening process.

[0014] According to some embodiments of the present utility model, the conveying component includes a conveyor belt and driving rollers. Both ends of the conveyor belt are respectively wound around the driving rollers. The stable operation of the conveyor belt can effectively avoid the scattering and accumulation of feed raw materials during the conveying process, ensuring the stability and reliability of the conveying process.

[0015] According to some embodiments of the present utility model, a plurality of magnetic strips are provided on the conveyor belt, and the magnetic strips are evenly distributed along the movement direction of the conveyor belt. The evenly distributed magnetic strips on the conveyor belt can effectively adsorb magnetic impurities in the feed raw materials, such as iron nails, bolts, etc., during the conveying process, and prevent the magnetic separation impurities from falling during the conveying process.

[0016] According to some embodiments of the present utility model, a shock-absorbing pad is provided at the bottom of the vibration strut. The shock-absorbing pad can effectively reduce the vibration generated by the vibration strut during the working process, reduce the impact on the material selection frame and the surrounding environment, and improve the stability of the equipment and the comfort of the working environment.

By setting the vibration component to reciprocate the material selection frame 1, the feed raw materials can be effectively vibrated and evenly distributed in the material selection frame 1. Then, by controlling the opening and closing of the blanking groove through the opening and closing of the baffle 13, it is convenient for impurities such as iron nails to fall, and at the same time, the magnetic field generated by the electromagnetic generator can effectively adsorb magnetic impurities such as iron nails in the feed raw materials, so that these impurities fall from the blanking groove onto the conveying component, ensuring the precise separation of the feed raw materials and improving the feed quality.

[0027] Furthermore, one end of the baffle 13 is hinged to the blanking groove, and the blanking groove is opened and closed by the flipping of the baffle 13.
