Description

Technical Field

[0001] This utility model relates to feed processing technology, specifically a feed screening device for feed processing. Background Technology

[0002] Grain harvesting is mostly done manually and by machine, which results in a lot of impurities being mixed into the grain used to make feed. This not only affects the quality of the feed and the feeding of livestock and poultry, but also large particles such as metal fragments and stones may injure the digestive tract and endanger the lives of livestock and poultry. Therefore, it is necessary to strictly screen the feed raw materials during the feed processing process, and a feed screening device is required in the screening process.

[0003] Existing feed ingredient screening typically employs vibrating screens. These screens use inclined mesh screens to filter and sieve feed ingredients, separating useful substances from impurities through continuous vibration. However, when encountering large, clumps of feed adhering together, the vibrating screen struggles to break them up with a short vibration cycle. This results in some of the useful substances in the clumps remaining unremoved, reducing the screening efficiency. Therefore, we propose a feed screening device for feed processing to address these problems. Utility Model Content

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figures 1-4As shown, a feed screening device for feed processing includes a vibrating screen 1, a top frame 2 on the vibrating screen 1, a cross frame 3 fixedly connected inside the top frame 2, an inclined groove 4 on the top of the cross frame 3, and sliding holes 5 evenly spaced from left to right inside the inclined groove 4; a dividing assembly, which includes three upper rods 6 slidably connected inside the sliding holes 5, wherein the top of the middle upper rod 6 is fixedly connected to a dome 7, a limiting plate 8 is fixedly connected to the upper outer side of the upper rod 6, a spring 9 is provided between the bottom of the limiting plate 8 and the inclined groove 4, the spring 9 is sleeved on the outer side of the adjacent upper rod 6, and a threaded connection is made to the lower outer side of the upper rod 6. The connecting sleeve 10 has a threaded connection to a lower rod 11 on its inner side. The lower rod 11 has two bent rods 12 fixedly connected to its outer front and rear sides respectively. The same cutting box 13 is fixedly connected to one end of several bent rods 12. The dividing assembly also includes two vertical plates 14 fixedly connected to the left and right sides of the top of the inclined groove 4 respectively. A rotating shaft 15 is rotatably connected between the two vertical plates 14. A motor 16 is fixedly connected to one side of one of the vertical plates 14. The output end of the motor 16 is fixedly connected to the adjacent end of the rotating shaft 15. A cam 17 is fixedly connected to the middle of the outer side of the rotating shaft 15. The side wall of the cam 17 abuts against the dome 7.

[0020] It should be noted that the crossbar 3 is used to fix the dividing assembly, the inclined groove 4 is used to match the inclination of the filter screen and the cutting box 13 to facilitate the installation of other components, the dome 7 can easily cooperate with the cam 17, and the cam 17 pushes the upper rod 6 and the lower rod 11 to move the cutting box 13 downward, the sliding hole 5 is used to guide the sliding of the upper rod 6, the limiting plate 8 can prevent the upper rod 6 from disengaging from the sliding hole 5 when it moves downward, and at the same time, it can facilitate the cooperation between the upper rod 6 and the spring 9. Affected by the upward action of the spring 9, the connecting sleeve 10 is used to facilitate the connection between the upper rod 6 and the lower rod 11, which can facilitate the installation of the cutting box 13. When necessary, the cutting box 13 can be removed. The cutting box 13 is used to cut the feed so that large pieces of feed are dispersed into small pieces, which are easier to be screened by vibration and improve the screening effect. The vertical plate 14 is used to install the rotating shaft 15, and the cam 17 is used to push the dome 7 to move. Through the set dividing components, the clumps of feed can be squeezed and crushed during the screening process, so that they are broken into several small pieces, which are easier to crush with vibration. This allows the useful raw materials in the clumps to be exposed, improving the output rate during screening and thus improving the screening effect of the feed.

[0021] The upper rod 6 and the lower rod 11 are both provided with threads. The upper rod 6 and the lower rod 11 have the same outer diameter. The threads facilitate the connection and fixation of the upper rod 6 and the lower rod 11 with the connecting sleeve 10, simplifying the difficulty and complexity of connection and disassembly.

[0022] The outer center of the connecting sleeve 10 is provided with a recessed part, and the recessed part is evenly distributed with anti-slip texture. The anti-slip texture can increase the grip resistance when the user holds it, making it easier to rotate the connecting sleeve 10, and thus making it easier for the user to operate.

[0023] The cutting box 13 has several cavities inside. The length of the cutting box 13 is adapted to the width of the filter screen. The cavities inside the cutting box 13 can be set into several specifications according to the type of feed. When it needs to be replaced, the cutting box 13 can be easily replaced and disassembled by separating the lower rod 11 and the upper rod 6.

[0024] In the specific implementation of this utility model: First, select a cutting box 13 of appropriate specifications according to the type of feed. Rotate the connecting sleeve 10 on the lower rod 11 to make it threaded and connected with the connecting sleeve 10. Then, move the cutting box 13 directly below the upper rod 6, so that the upper rod 6 is aligned with different connecting sleeves 10. Rotate the connecting sleeve 10 in the opposite direction to reduce the connection area with the lower rod 11 and increase the connection area with the upper rod 6, thus completing the installation of the cutting box 13. Then, connect the device to an external power source and control the vibrating screen 1 and the motor 16 to work through the controller. When the vibrating screen 1 works, it causes the entire filter screen to vibrate. When the motor 16 works, it drives the cam 17 to rotate through the rotating shaft 15. When the cam 17 rotates, it will contact the dome 7 and perform a rotation. The compression pushes the upper rod 6 in the middle downward through the dome 7, which in turn drives the cutting box 13 downward through the connecting sleeve 10, lower rod 11, and bent rod 12. At the same time, the upper rods 6 on both sides and other structures move synchronously. Simultaneously, the limiting plate 8 compresses the spring 9, causing the spring 9 to shorten and store elastic force, so that the cutting box 13 cuts the feed on the filter screen into pieces. When the cam 17 rotates to the point with a smaller radius and points downward, it no longer exerts a downward force on the dome 7. At this time, the limiting plate 8 will drive the upper rod 6, connecting sleeve 10, and cutting box 13 to move upward under the elastic force of the spring 9, so that the dome 7 continues to abut against the cam 17, ensuring that there is always a force relationship between the dome 7 and the cam 17, so as to realize the reciprocating movement of the cutting box 13 in the vertical direction.

[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
