Description

Technical Field

[0001] This invention relates to the field of mixing technology, specifically to an automatic raw material screening device. Background Technology

[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed ingredients such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] Referring to patent application CN 215386815 U, an assistive sleep device for treating psychological problems is described, specifically an assistive sleep device for treating psychological problems, relating to the field of assistive sleep device technology. An assistive sleep device for treating psychological problems includes a support plate, a support frame fixedly connected to the bottom of the support plate, a sponge pad provided on the top of the support plate, and a housing fixedly connected to one bottom end of the support plate. A drive shaft is rotatably connected between the inner walls of the two sides of the bottom of the housing.

[0004] Currently, feed pellets are typically separated by gravity falling naturally, accompanied by various vibrations and agitation during the screening process. However, the efficiency of gravity-based separation is low, as the falling force is limited, causing feed to easily get stuck and unable to fall through the screening holes. This screening method is therefore inefficient. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic raw material screening device, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic raw material screening device, comprising a screening box, a top cover hinged to the top of the screening box, a feed inlet fixedly connected to the top of the top cover, a connecting block fixedly connected to the outer wall of the screening box, a support rod fixedly connected to the bottom of the connecting block, a base plate fixedly connected to the bottom of the support rod, a motor fixedly connected to the bottom of the screening box, and a centrifugal screening mechanism provided inside the screening box;

[0007] The centrifugal sieving mechanism includes:

[0008] A turntable, which is a circular disc structure, has a collection plate rotatably connected to its outer wall. The outer wall of the collection plate is fixedly connected to the inner wall of the screening box. A rotating rod is fixedly connected to the bottom of the turntable. One end of the rotating rod is fixedly connected to the output end of a motor. A ring is fixedly connected to the top of the turntable. An arc-shaped plate is fixedly connected to the top of the ring. The turntable is driven by the rotating rod to rotate clockwise.

[0009] The sieve hole is a circular groove structure. A square groove is opened on the outer wall of the actuating plate. A cutting blade is fixedly connected to the inner wall of the square groove. The sieve hole is opened on the inner wall of the arc plate. A connecting plate is fixedly connected to the outer wall of the arc plate. The outer wall of the connecting plate is fixedly connected to the outer wall of the actuating plate.

[0010] Preferably, the inner wall of the turntable is provided with a feeding groove, the feeding groove is an arc-shaped groove structure, the inner wall of the feeding groove is inclined, a lever is fixedly connected to the inner wall of the feeding groove, the lever is inclined, and a lever separation mechanism is provided on the top of the turntable.

[0011] Preferably, the actuating separation mechanism includes a fixed ring, a long rod is fixedly connected to the outer wall of the fixed ring, one end of the long rod is fixedly connected to the inner wall of the screening box, and the outer wall of the fixed ring is rotatably connected to the turntable and the inner wall of the circular ring.

[0012] Preferably, a fixing rod is fixedly connected to the outer wall of the fixing ring, and a through groove is provided on the inner wall of the actuating plate. The height of the inner wall of the through groove is greater than the diameter of the fixing rod, so that the fixing rod can pass through the inside of the through groove.

[0013] Preferably, the inner wall of the fixing ring is provided with an arc-shaped groove, and a stop bar is fixedly connected to the top and bottom of the inner wall of the arc-shaped groove. The stop bar is a circular rod-shaped structure, thereby separating and breaking up the particles.

[0014] Preferably, a connecting column is fixedly connected to the outer wall of the fixed ring, and a scraper is fixedly connected to one end of the connecting column. The outer wall of the scraper contacts the outer wall of the arc-shaped plate, thereby scraping the outer wall of the arc-shaped plate.

[0015] Preferably, the inner wall of the connecting plate has a groove A and a groove B, thereby ensuring that the connecting column and the scraper can pass through normally.

[0016] Preferably, the top of the ring is an inclined surface, the top of the turntable is a flat surface, and the inner wall of the feeding trough is connected to the inside of the screening box, thereby allowing the air inside to communicate.

[0017] This invention provides an automatic raw material screening device, which has the following beneficial effects:

[0018] 1. This invention features a centrifugal sieving mechanism. As the rotating rod rotates, the turntable rotates synchronously. When the turntable rotates, it drives the top actuating plate and cutting blade to rotate synchronously, throwing the particles falling on the turntable outwards. The particles are then propelled onto the arc-shaped plate by the actuating plate and cutting blade, and discharged outwards through the sieving holes on the inner wall of the arc-shaped plate. Particles smaller than the sieving holes are fully thrown out, while particles larger than the sieving holes cannot be thrown out. Furthermore, as the particles fall, they are also cut and separated by the cutting blade, dividing a large number of particles evenly into four parts on the turntable. Through a fully automatic rotary centrifugal separation method, the particles are separated outwards under high pressure, improving the screening speed and efficiency.

[0019] 2. This invention, by setting up a centrifugal sieving mechanism, allows particles to automatically slide down onto a turntable. As they continue to roll due to inertia, they fall into the feed trough on the turntable. This allows particles that cannot be separated and filtered by the sieving holes to fall into the interior of the sieving box through the larger opening of the feed trough. Particles separated by the sieving holes fall onto the collection plate outside the turntable, achieving automatic classification and separation of particles of different sizes. It also allows for the continued addition of particles through the feed inlet to achieve automatic separation and mixing. This eliminates the need to remove the large particles after each sieving process and then add new particles, thus avoiding wasted time and effort.

[0020] 3. This invention, by setting up a centrifugal screening mechanism, pushes the particles upward and outward again. At the same time, the paddle is also inclined, so the turntable rotates clockwise. This pushes the particles that fall into the feed trough upward with the inclined surface of the paddle and the clockwise rotation, preventing the particles from falling out of the feed trough. The rotation of the paddle driven by the turntable also fully throws the particles upward. In addition to being pushed by the paddle plate, the particles can also move towards the arc plate with the paddle, and are thrown outward in a throwing and dispersing manner, avoiding the particles from being uniformly concentrated at the bottom of the arc plate, further improving the uniformity and screening efficiency of screening through the screening holes of the arc plate.

[0021] 4. By setting up a toggle separation mechanism, when the particles are thrown out, the fixed ring penetrating the turntable is fixed by the long rod at the bottom. Thus, when the turntable rotates, the fixed ring remains stationary, while the fixed rod on the fixed ring continuously toggles with the particles. As the particles are thrown outward, they can be toggled and separated by the fixed rod, further improving the effect of evenly covering the particles in the numerous screening holes of the arc plate. Furthermore, the rotation of the toggle plate is prevented from interfering with the fixed rod by the through groove opened in the inner wall.

[0022] 5. This invention, through the setting of a tossing separation mechanism, when particles are thrown outward through the arc-shaped groove inside the fixed ring, they collide with the baffle in the arc-shaped groove and are effectively blocked by the baffle, achieving sieving and separation. The particles are separated into multiple equal parts and thrown onto the arc-shaped plate, and the clumps of particles that are stuck together are broken up, which greatly improves the separation and crushing effect of particles and the efficiency of passing through the sieve holes. With the rotation of the arc-shaped plate, the outer wall of the arc-shaped plate is constantly scraped by the scraper, and the scraper is fixed by the fixed ring through the connecting column, thereby completing the tossing of the particles accumulated on the surface of the arc-shaped plate. This causes the particles accumulated on the arc-shaped plate to be tossed and turned over by centrifugal throwing, and the particles that should have passed through the sieve holes are pushed to the outside by turning over and being thrown out by centrifugal throwing. This ensures the separation and breaking effect of particles, and also turns over the particles that need to be separated, avoiding the problem of accumulation and difficulty in sieving.

[0036] Example 1:

[0037] Please see Figure 1-3 The present invention provides a technical solution: an automatic raw material screening device, including a screening box 2, a top cover 9 hinged to the top of the screening box 2, a feed inlet 8 fixedly connected to the top of the top cover 9, a connecting block 7 fixedly connected to the outer wall of the screening box 2, a support rod 1 fixedly connected to the bottom of the connecting block 7, a bottom plate 10 fixedly connected to the bottom of the support rod 1, a motor 5 fixedly connected to the bottom of the screening box 2, and a centrifugal screening mechanism 3 provided inside the screening box 2;

[0038] Centrifugal screening mechanism 3 includes:

[0039] Turntable 301 is a circular disc structure. A collection plate 11 is rotatably connected to the outer wall of turntable 301. The outer wall of collection plate 11 is fixedly connected to the inner wall of screening box 2. A rotating rod 6 is fixedly connected to the bottom of turntable 301. One end of rotating rod 6 is fixedly connected to the output end of motor 5. A ring 302 is fixedly connected to the top of turntable 301. An arc plate 303 is fixedly connected to the top of ring 302. Turntable 301 is driven by rotating rod 6 to rotate clockwise.

[0040] The sieve hole 305 is a circular groove structure. The outer wall of the actuating plate 306 is provided with a square groove 307. The inner wall of the square groove 307 is fixedly connected with a cutting blade 308. The inner wall of the arc plate 303 is provided with a sieve hole 305. The outer wall of the arc plate 303 is fixedly connected with a connecting plate 304. The outer wall of the connecting plate 304 is fixedly connected with the outer wall of the actuating plate 306.

[0041] The particles to be screened are quantitatively fed into the feed inlet 8 and fall into the screening box 2, entering the turntable 301. At the same time, the motor 5 is started to drive the rotating rod 6 to rotate. As the rotating rod 6 rotates, the turntable 301 rotates synchronously. When the turntable 301 rotates, the top actuating plate 306 and the cutting blade 308 rotate synchronously, throwing the particles falling on the turntable 301 outward with the rotation. They are then pushed onto the arc plate 303 by the actuating plate 306 and the cutting blade 308 and discharged outward through the screening holes 305 opened on the inner wall of the arc plate 303. Particles smaller than the screening holes 305 are fully thrown out, while particles larger than the screening holes 305 cannot be thrown out. As the particles fall, they are also cut and separated by the cutting blade 308, dividing a large number of particles into four parts evenly on the turntable 301. Through a fully automatic rotary centrifugal separation method, the particles are separated outward under high pressure, improving the screening speed and efficiency.

[0042] Example 1:

[0043] Please see Figure 1-10 Based on Embodiment 1, the present invention provides a technical solution: a feeding groove 310 is provided on the inner wall of the turntable 301. The feeding groove 310 has an arc-shaped groove structure and the inner wall of the feeding groove 310 is inclined. A paddle 309 is fixedly connected to the inner wall of the feeding groove 310. The paddle 309 is inclined. A paddle separation mechanism 4 is provided on the top of the turntable 301.

[0044] After the motor 5 drives the rotating rod 6 to rotate for a period of time, when the motor 5 is turned off, the rotating disk 301 automatically performs rapid centrifugal separation and screening of the particles on the rotating disk 301. The particles at the arc plate 303 will slide and roll down on the inclined surface of the ring 302 due to their own gravity. The particles will automatically slide down onto the rotating disk 301 and continue to roll due to inertia, falling into the feeding trough 310 opened on the rotating disk 301. The particles that cannot be separated and filtered by the screening holes 305 will fall into the interior of the screening box 2 through the larger opening of the feeding trough 310. The particles separated by the screening holes 305 will fall onto the collection plate 11 outside the rotating disk 301, realizing the automatic classification and separation of particles of different sizes. It can also meet the need to continue to add plant particles through the feed port 8 to continue to achieve automatic separation and mixing. It is not necessary to take out the large particles after each screening and then put in new particles, which would waste time and effort.

[0045] Furthermore, when the particles are centrifugally pushed outward by the rotating turntable 301, driving the agitator plate 306 and the cutting blade 308, they will not fall down through the feeding trough 310. This is because the inner wall of the feeding trough 310 is inclined. Even if the particles fall onto the feeding trough 310, they will first roll downward along the inclined surface of the feeding trough 310. However, because the feeding trough 310 is inclined, the distance and time required for the particles to roll down are longer. Therefore, before the particles have passed through the downward channel of the feeding trough 310, they will be agitated by the clockwise rotation of the agitator plate 309, applying outward centrifugal force to the particles. As the particles are thrown outward by the centrifugal motion, they also begin to move upward on the inclined surface of the feeding trough 310. Then, by pushing it upwards and outwards again, and since the paddle 309 is also inclined, the turntable 301 rotates clockwise. This pushes the particles that have fallen into the feed trough 310 upwards with the inclined surface of the paddle 309 and the clockwise rotation, preventing the particles from falling out of the feed trough 310. The rotation of the paddle 309 driven by the turntable 301 also throws the particles upwards. The particles are not only moved by the paddle plate 306, but also move towards the arc plate 303 with the paddle 309. They are thrown outwards in a throwing and dispersing manner, preventing the particles from being concentrated at the bottom of the arc plate 303. This further improves the uniformity and efficiency of screening through the screening holes 305 of the arc plate 303.

[0046] Example 3:

[0047] Please see Figure 1-12 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the agitator separation mechanism 4 includes a fixed ring 401, a long rod 410 is fixedly connected to the outer wall of the fixed ring 401, one end of the long rod 410 is fixedly connected to the inner wall of the screening box 2, and the outer wall of the fixed ring 401 is rotatably connected to the inner wall of the turntable 301 and the ring 302.

[0048] A fixing rod 402 is fixedly connected to the outer wall of the fixing ring 401, and a through groove 403 is opened on the inner wall of the actuating plate 306. The height of the inner wall of the through groove 403 is greater than the diameter of the fixing rod 402.

[0049] The inner wall of the fixing ring 401 is provided with an arc-shaped groove 404, and the top and bottom of the inner wall of the arc-shaped groove 404 are fixedly connected with a stop bar 405, which is a circular rod structure.

[0050] A connecting post 406 is fixedly connected to the outer wall of the fixing ring 401. A scraper 407 is fixedly connected to one end of the connecting post 406. The outer wall of the scraper 407 is in contact with the outer wall of the arc plate 303.

[0051] The inner wall of the connecting plate 304 has a groove A408 and a groove B409.

[0052] The top of the ring 302 is an inclined surface, the top of the turntable 301 is a flat surface, and the inner wall of the feeding trough 310 is connected to the inside of the screening box 2.

[0053] When the particles are thrown out, the fixing ring 401 that runs through the turntable 301 is fixed by the long rod 410 at the bottom. So when the turntable 301 rotates, the fixing ring 401 remains fixed, while the fixing rod 402 on the fixing ring 401 continuously moves with the particles. As the particles are thrown outward, they can be moved and separated by the fixing rod 402, which further improves the effect of evenly covering the particles in the numerous screening holes 305 on the arc plate 303. Furthermore, the rotation of the agitator plate 306 is prevented from interfering with the fixing rod 402 by the through groove 403 opened on the inner wall.

[0054] Simultaneously, as the particles are thrown outward, they pass through the arc-shaped groove 404 inside the fixed ring 401 and impact the baffle 405 within the arc-shaped groove 404. The baffle 405 thoroughly separates and divides the particles, throwing them onto the arc-shaped plate 303 in equal portions. This process also breaks up any clumps of particles that are stuck together, significantly improving the separation and crushing effect of the particles and the efficiency of passing through the screening holes 305. Furthermore, as the arc-shaped plate 303 rotates, its outer wall continuously scrapes against the scraper 407. The scraper 407 is fixed by the fixing ring 401 through the connecting column 406, thereby fully agitating the particles accumulated on the surface of the arc plate 303. This causes the particles accumulated on the arc plate 303 to be agitated and flipped, so that the particles that should have passed through the sieve hole 305 are squeezed to the outside. The particles are then agitated and flipped to the sieve hole 305 and flung out by centrifugal swing. This ensures the separation and dispersion of particles while also flipping the particles that need to be separated, avoiding the problem of accumulation and difficulty in sieving.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
