Description

Technical Field

[0001] The utility model relates to the technical field of feed screening, in particular to feed processing and screening equipment. Background Art

[0002] Feed is a general term for food used to feed animals. Its raw materials include more than ten varieties such as soybeans, soybean meal, corn, fish meal, grains, feed additives, etc. Among them, the feed used to feed fish, shrimp, etc., mainly consists of protein, fat, vitamins and minerals. During the feed processing, it needs to be screened by a screening device. However, the existing screening device is easy to adhere to the feed guide plate during the feed guiding process, and it needs to be manually cleaned.

[0003] For this purpose, we propose a feed processing and screening device. Utility Model Content

[0004] The utility model aims to provide a feed processing and screening device which is simple to operate and can clean a material guide plate.

[0005] The utility model is achieved through the following measures:

[0006] A feed processing and screening device, characterized in that it comprises a support frame, on which a lower hopper, a sieve plate, a lower material plate and a cleaning mechanism cooperating with the lower material plate are arranged, the sieve plate is obliquely arranged below the lower hopper and the high side of the sieve plate is close to the lower hopper, the lower material plate is obliquely arranged below the sieve plate and the high side of the lower material plate is close to the low side of the sieve plate;

[0007] The cleaning structure includes a pair of guide rods respectively arranged on both sides of the support frame through a bracket plate, and a scraper is arranged on the pair of guide rods to scrape off the feed adhered to the unloading plate and can move along the guide rods. After being screened by the screen plate, the feed falls on the unloading plate and slides from the high side of the unloading plate to the low side of the unloading plate; when working, the scraper moves from the high side to the low side of the unloading plate, thereby scraping off the feed adhered to the unloading plate.

[0008] The specific features of the utility model also include:

[0009] The outer periphery of the guide rod on one side is provided with an external thread and is rotatably provided on the bracket plate on the corresponding side. The corresponding side of the scraper is provided on the outer periphery of the guide rod through a corresponding threaded hole. A motor is provided on the bracket plate on the corresponding side. The output shaft of the motor is connected to the corresponding guide rod. When the motor is started, it drives the guide rod with the external thread to rotate, thereby driving the scraper to move along the guide rod, so as to scrape off the feed adhered to the scraper.

[0010] The scraper includes a mounting plate arranged on a pair of guide rails, and a mounting groove is arranged on the side of the mounting plate facing the lower side of the unloading plate, and the lower side surface in the mounting groove passes through the lower side edge of the mounting plate, and a rotating shaft is arranged between the vertical side surfaces on both sides of the mounting groove, and a scraping plate cooperating with the upper side surface of the unloading plate is arranged on the periphery of the rotating shaft. When the scraper is working, the scraper plate can be used to scrape off the feed adhered to the unloading plate. At this time, the bottom surface of the mounting groove plays a limiting role on the scraper plate. When the scraper is reset, the scraper plate can rotate, thereby avoiding the problem of scraping the feed upwards.

[0011] A rectangular frame is transversely arranged on one side of the support frame, a through slide groove is arranged on the upper side of the rectangular frame, and a slide plate is arranged in the slide groove, which slides up and down and cooperates with the scraper plate.

[0012] A round rod is provided on the outer side surface of the scraper plate, and a long strip plate cooperating with the slide plate is provided at the free end of the round rod. When the scraper plate is working, the slide plate moves down into the rectangular frame, and before the scraper plate is reset, the slide plate moves up. During the resetting process of the scraper plate, the long strip plate will rotate a certain angle under the action of the slide plate, and through the transmission of the round rod, the scraper plate will also rotate a certain angle, so that the lower side of the scraper plate leaves the unloading plate, further avoiding the problem of scraping the feed net during the resetting process of the scraper plate.

[0013] A first card slot is provided on one side of the slide plate close to the high side of the blanking plate, a second card slot is provided on the other side of the slide plate, and a side surface of the first card slot close to the low side of the blanking plate is provided as an inclined surface;

[0014] A plurality of springs are arranged between the lower side surface of the slide plate and the lower side surface inside the rectangular frame, one end of the spring is fixed on the slide plate, and the other end of the spring is fixed on the lower side surface inside the rectangular frame. When the scraper is working, the long strip plate is in the first slot in the initial position. As the scraper moves, the long strip plate slides along the inclined surface, pressing the slide plate downward during the sliding process, and finally the slide plate overcomes the elastic force of the spring and is pressed into the slide groove. The scraper continues to move, and the scraper plate will scrape off the feed adhered to the unloading plate. When the scraper moves to the lower side end and the long strip plate enters the second slot, the slide plate is reset under the action of the spring, and then the scraper is reset and moved. Under the action of the slide plate, the long strip plate is lifted up to a certain angle, so that the scraper plate rotates upward to a certain angle.

[0015] Torsion springs are provided on the periphery of the rotating shaft on both sides of the scraper plate, one end of the torsion spring is fixed to the side surface of the scraper plate, and the other end of the torsion spring is fixed to the corresponding side surface in the mounting groove. Under the action of the torsion spring, the scraper plate remains in contact with the bottom surface of the mounting groove. The setting of the torsion spring ensures that the scraper plate can be reset in time after entering the slot and leaving the inclined surface, thereby avoiding loss of scraping effect.

[0016] Working process: when the scraper is working, the long plate is in the first slot in the initial position, and as the scraper moves, the long plate slides along the inclined surface, and the slide plate will be pressed downward during the sliding process, and finally the slide plate will overcome the elastic force of the spring and be pressed into the slide groove. The scraper continues to move, and the scraper plate will scrape off the feed adhered to the discharge plate. When the scraper moves to the lower side end and the long plate enters the second slot, the slide plate is reset under the action of the spring, and then the scraper resets and moves. Under the action of the slide plate, the long plate is lifted up at a certain angle, so that the scraper plate rotates upward at a certain angle, thereby leaving the upper surface of the discharge plate, avoiding the problem of scraping the feed upward.

[0017] The beneficial effects of the utility model are as follows: the equipment has a simple structure and is easy to operate. The scraper can effectively scrape off the feed adhering to the unloading plate, thus avoiding manual cleaning, saving labor and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0026] See also Figure 1-3 A feed processing and screening device comprises a support frame 1, on which a lower hopper 2, a sieve plate 3, a lowering plate 4 and a cleaning mechanism matched with the lowering plate 4 are arranged, the sieve plate 3 is arranged obliquely below the lower hopper 2 and the high side of the sieve plate 3 is close to the lower hopper 2, the lowering plate 4 is arranged obliquely below the sieve plate 3 and the high side of the lowering plate 4 is close to the low side of the sieve plate 3;

[0027] The cleaning structure includes a pair of guide rods 15 respectively arranged on both sides of the support frame 1 through the bracket plate. The pair of guide rods 15 are provided with scrapers that can scrape off the feed adhering to the unloading plate 4 and can move along the guide rods 15. After being screened by the screen plate 3, the feed falls on the unloading plate 4 and slides from the high side of the unloading plate 4 to the low side of the unloading plate 4; when working, the scraper moves from the high side to the low side of the unloading plate 4, thereby scraping off the feed adhering to the unloading plate 4.

[0028] An external thread is arranged on the periphery of the guide rod 15 on one side and is rotatably arranged on the bracket plate on the corresponding side. The corresponding side of the scraper is arranged on the periphery of the guide rod 15 through the corresponding threaded hole. A motor 14 is arranged on the bracket plate on the corresponding side. The output shaft of the motor 14 is connected to the corresponding guide rod 15. When the motor 14 is started, it drives the guide rod 15 with the external thread to rotate, thereby driving the scraper to move along the guide rod 15, so as to scrape off the feed adhered to the scraper.

[0029] The scraper includes a mounting plate 10 arranged on a pair of guide rods 15, and a mounting groove 16 is arranged on the side of the mounting plate 10 facing the lower side of the unloading plate 4, and the lower side surface in the mounting groove 16 passes through the lower side edge of the mounting plate 10, and a rotating shaft is arranged between the vertical side surfaces on both sides of the mounting groove 16, and a scraping plate 11 cooperating with the upper side surface of the unloading plate 4 is arranged on the periphery of the rotating shaft. When the scraper is working, the scraping plate 11 can scrape off the feed adhered to the unloading plate 4. At this time, the bottom surface of the mounting groove 16 plays a limiting role on the scraping plate 11. When the scraper is reset, the scraping plate 11 can rotate, thereby avoiding the problem of scraping the feed upwards.

[0030] A rectangular frame 13 is transversely arranged on one side of the support frame 1 , and a through slide groove is arranged on the upper side of the rectangular frame 13 . A slide plate 8 is arranged in the slide groove and slides up and down and cooperates with the scraper plate 11 .

[0031] A round rod is provided on the outer side of the scraper plate 11, and a long strip plate 9 cooperating with the slide plate 8 is provided at the free end of the round rod. When the scraper is working, the slide plate 8 moves down to the rectangular frame 13, and before the scraper is reset, the slide plate 8 moves up. During the resetting process of the scraper, the long strip plate 9 will rotate a certain angle under the action of the slide plate 8, and through the transmission of the round rod, the scraper plate 11 will also rotate a certain angle, so that the lower side of the scraper plate 11 leaves the unloading plate 4, further avoiding the problem of scraping the feed net during the resetting process of the scraper.

[0032] A slot 1 6 is provided on one side of the slide plate 8 close to the high side of the blanking plate 4, a slot 2 12 is provided on the other side of the slide plate 8, and an inclined surface 5 is provided on the side of the slot 1 6 close to the low side of the blanking plate 4;

[0033] A plurality of springs 7 are arranged between the lower side surface of the slide plate 8 and the lower side surface inside the rectangular frame 13, one end of the spring 7 is fixed on the slide plate 8, and the other end of the spring 7 is fixed on the lower side surface inside the rectangular frame 13. When the scraper is working, the long strip plate 9 is in the slot 1 6 in the initial position. As the scraper moves, the long strip plate 9 slides along the inclined surface 5, and the slide plate 8 is pressed downward during the sliding process, and finally the slide plate 8 overcomes the elastic force of the spring 7 and is pressed into the slide groove. The scraper continues to move, and the scraper plate 11 will scrape off the feed adhered to the unloading plate 4. When the scraper moves to the lower side end and the long strip plate 9 enters the slot 2 12, the slide plate 8 is reset under the action of the spring 7, and then the scraper resets and moves. Under the action of the slide plate 8, the long strip plate 9 is lifted up to a certain angle, so that the scraper plate 11 rotates upward to a certain angle.

[0034] Torsion springs are provided on the periphery of the rotating shaft on both sides of the scraper plate 11, one end of the torsion spring is fixed on the side of the scraper plate 11, and the other end of the torsion spring is fixed on the corresponding side surface in the mounting groove 16. Under the action of the torsion spring, the scraper plate 11 remains in contact with the inner bottom surface of the mounting groove 16. The setting of the torsion spring ensures that the scraper plate 11 can be reset in time after entering the slot 6 and leaving the inclined surface 5, thereby avoiding loss of the scraping effect.

[0035] Working process: When the scraper is working, the long strip plate 9 is in the card slot 1 6 in the initial position. As the scraper moves, the long plate slides along the inclined surface 5. During the sliding process, the slide plate 8 will be pressed downward, and finally the slide plate 8 will overcome the elastic force of the spring 7 and be pressed into the slide groove. The scraper continues to move, and the scraper plate 11 will scrape off the feed adhered to the unloading plate 4. When the scraper moves to the lower side end and the long strip plate 9 enters the card slot 2 12, the slide plate 8 is reset under the action of the spring 7, and then the scraper resets and moves. Under the action of the slide plate 8, the long strip plate 9 is lifted up at a certain angle, so that the scraper plate 11 rotates upward at a certain angle, thereby leaving the upper surface of the unloading plate 4, avoiding the problem of scraping the feed upward.
