Description

Technical Field

[0001] This utility model relates to the field of feed batching scale technology, specifically to an anti-clogging device for feed batching scales. Background Technology

[0002] A feed weighing system is a device that combines different raw materials into a new formula product through a specified formula. It is used in various industries, especially in the field of feed formulation. By optimizing the combination of different feed ingredients, the nutritional needs of animals can be met. For example, soybean meal, corn and other raw materials are mixed in a certain proportion to process feed for pigs to ensure that the pigs can grow normally.

[0003] Feed batching scales mix feed during use. During this process, some feed may stick to the discharge port of the scale, easily causing blockage. Therefore, most batching scales use vibration by tapping the outer wall of the scale to dislodge the feed from the hopper. However, vibration can only remove some of the sticky feed, and some feed will still remain at the discharge port, thus reducing the effectiveness of cleaning the scale's outlet. Furthermore, tapping can loosen parts on the scale and reduce the batching accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-clogging device for a feed batching scale. This device solves the problem of preventing blockage at the feed batching scale outlet by tapping and vibrating, which is a traditional method. It also avoids leaving residues when cleaning feed adhering to the feed batching scale outlet, improves the cleaning effect, and prevents loosening of parts in the feed batching scale during the cleaning process, thus avoiding a reduction in the batching accuracy of the scale.

[0008] Preferably, the limiting component includes a limiting rod, and the limiting rod is slidably connected to another set of moving blocks, and the two ends of the limiting rod are fixedly connected to the supporting side plate.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a feed batching scale anti-blocking device, including a support frame 1, a pressure sensor 2 fixedly connected to the upper surface of the support frame 1, a batching box 3 fixedly connected to the upper end of the pressure sensor 2, a discharge port 303 opened at the lower end of the batching box 3, a protective cover 601 provided inside the discharge port 303, a motor II 6 fixedly installed on the lower surface of the protective cover 601, a drive shaft 605 fixedly connected to the upper end of the motor II 6 through the protective cover 601, a cleaning rod 606 fixedly connected to the side surface of the drive shaft 605, a crossbar 602 symmetrically fixedly connected to the side surface of the protective cover 601, a moving block 502 fixedly connected to one end of the crossbar 602, a driving mechanism provided inside one set of moving blocks 502, a limiting component provided inside the other set of moving blocks 502, and scraper plates 301 symmetrically provided on the inner side wall of the batching box 3.

[0021] As a technical optimization of this utility model, the sweeping rod 606 gradually shortens from top to bottom along the drive shaft 605, and one end of the sweeping rod 606 is always in contact with the inner wall of the feed box 3, so as to remove the feed adhering to the inclined surface at the lower end of the feed box 3.

[0022] As a technical optimization of this utility model, the driving mechanism includes a reciprocating screw 503, which is threadedly connected to a set of moving blocks 502. One end of the reciprocating screw 503 is rotatably connected to a support side plate 5, and the other end of the reciprocating screw 503 is fixedly connected to a motor I4. One side surface of the support side plate 5 is fixedly connected to the outer surface of the mixing box 3. The driving mechanism can push the protective cover 601 to move along the discharge port 303, thereby enabling a comprehensive cleaning of the discharge port 303.

[0023] As a technical optimization of this utility model, the limiting component includes a limiting rod 501, which is slidably connected to another set of moving blocks 502. The two ends of the limiting rod 501 are fixedly connected to the supporting side plate 5. The limiting rod 501 and the supporting side plate 5 can limit the protective cover 601, thereby improving the stability of the protective cover 601.

[0024] As a technical optimization of this utility model, a horizontal plate 604 is fixedly connected to the lower end of the scraper 301, and a support plate 603 is fixedly connected to the middle of the horizontal plate 604. One end of the support plate 603 is fixedly connected to the side surface of the protective cover 601. The angle between the support plate 603 and the horizontal bar 602 is 90 degrees. The support plate 603 and the horizontal plate 604 can push the scraper 301 to move when the protective cover 601 moves, thereby scraping and cleaning the inner wall of the mixing box 3, thus further improving the cleaning effect of the mixing box 3.

[0025] As a technical optimization of this utility model, a belt 401 is sleeved on one side surface of the motor I4, and a pulley 402 is sleeved on one end of the belt 401. A stirring shaft 305 is fixedly connected to one side surface of the pulley 402. One end of the stirring shaft 305 passes through the feed box 3 and is rotatably connected to the inner wall of the feed box 3. A stirring rod 302 is fixedly connected to the side surface of the stirring shaft 305. Through the interaction of the stirring rod 302, the stirring shaft 305, the belt 401, the pulley 402 and the motor I4, the feed inside the feed box 3 can be stirred and mixed.

[0026] In use, feed is first poured into the feed bin 3, and then the motor I4 in the drive mechanism is started. At this time, the motor I4 will drive the belt 401 and pulley 402 to rotate. Therefore, the pulley 402 will drive the stirring rod 302 to rotate through the stirring shaft 305. At this time, the stirring rod 302 will stir and mix the feed inside the feed bin 3. During the stirring and mixing process, the motor I4 will push the motor II6 and the protective cover 601 to move along the discharge port 303 through the reciprocating screw 503 and the moving block 502. At the same time, the motor II6 is started. The motor II6 will drive the drive shaft 605 and the cleaning rod 606 to rotate. Thus, the cleaning rod 606 will remove the feed adhering to the inner wall of the discharge port 303. At the same time, when the protective cover 601 moves, the scraper 301 will also move with the protective cover 601. Thus, the scraper 301 will scrape the inner wall of the feed bin 3 to prevent feed from sticking to the inner wall of the feed bin 3.
