Description

Technical Field

[0001] This utility model belongs to the field of pig feed trough technology, specifically an automatic cleaning and scraping device for pig feed trough residue. Background Technology

[0002] In large-scale pig farming, the cleanliness and management of feed troughs is a key link in ensuring the healthy growth of pigs and the efficiency of breeding. The cleaning of feed trough residue in traditional pig houses mostly relies on manual operation. Not only do farmers need to enter the pens regularly to manually scrape off the residual feed in the troughs, but they also need to clean each discharge port one by one. This results in high labor intensity and low cleaning efficiency. Especially in large-scale breeding scenarios, manual cleaning is difficult to guarantee in a timely manner.

[0003] In addition, although some existing automated cleaning devices can achieve mechanical drive of the scraper, the opening and closing of the discharge port often requires an additional power source, such as an independent motor or cylinder control. This not only increases the structural complexity and manufacturing cost of the equipment, but may also lead to asynchronous cleaning and discharge due to poor coordination of multiple power sources. If the discharge port opens late, the residue pushed by the scraper is easy to accumulate in the trough; if it is not closed in time, feed may leak out from the discharge port during normal feeding, affecting the stability and practicality of the device. Therefore, we propose an automatic scraper for cleaning residue in pigsty feed troughs. Utility Model Content

[0004] The purpose of this invention is to provide an automatic scraping device for cleaning pig feed trough residue, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning and scraping device for pigsty feed troughs, comprising a feed trough, a screw at the bottom of the feed trough, an internally threaded slider screwed to the outside of the screw, two sets of first wedges evenly arranged on the front and rear sides of the feed trough, a push plate inside the feed trough, a set of scrapers on both the left and right sides of the push plate, a first connecting plate at the top of the push plate, the first wedges evenly arranged between the first connecting plate and the internally threaded slider, a set of discharge ports penetrating through the left and right sides of the feed trough, a sealing plate inside the discharge port, a second connecting plate at the top of the sealing plate, a set of second wedges on both the front and rear sides of the second connecting plate, the second wedges corresponding to the first wedges.

[0006] Preferably, the second wedge is located on the outside of the feed trough, the second connecting plate and the first connecting plate are both located on the top of the feed trough, and the discharge port penetrates through the top of the feed trough.

[0007] Preferably, the top of the feed trough is provided with uniformly spaced mounting holes, each mounting hole is equipped with a spring, the top of the spring is provided with a guide rod, and the top of the guide rod passes through the mounting hole and connects to the bottom of the second connecting plate.

[0008] Preferably, a set of support sleeves is provided on both the left and right sides of the bottom of the feed trough, and the screw is set in the two sets of support sleeves. A servo motor is provided on the right side of the right support sleeve, and the right side of the screw is connected to the output end of the servo motor.

[0009] Preferably, a set of guide plates is provided on both the left and right sides of the feed trough, and the guide plates correspond to the discharge port of the feed trough.

[0010] Preferably, the guide plate is located outside the sealing plate, the servo motor is located below the guide plate, the bottom of the feed trough is evenly provided with support feet, the sealing plate has an installation cavity inside, and the installation cavity is provided with a configuration block.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by utilizing the wedge block linkage structure of the scraper and the sealing plate, the linear displacement of the scraper is converted into the opening and closing power of the sealing plate, eliminating the need for an independent drive component to control the discharge port, and reducing equipment costs and failure probability.

[0012] As the scraper moves, the wedge contact automatically triggers the opening of the sealing plate, ensuring that the residue is in the open state when it is pushed to the discharge port, thus preventing residue accumulation. After cleaning, the wedge disengages when the scraper resets, and the sealing plate automatically closes due to the weight of the counterweight and the spring's rebound force, ensuring that feed does not leak during normal feeding.

[0013] By installing the screw at the bottom of the feed trough and shielding the servo motor with a guide plate, residue can be prevented from contacting the screw and servo motor, thus preventing them from affecting normal operation and ensuring the reliability of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4An automatic scraping device for cleaning pig feed trough residue includes a feed trough 1. A screw 21 is rotatably mounted on the bottom of the feed trough 1. An internally threaded slider 17 is screwed onto the outer side of the screw 21. Two sets of first wedges 13 are evenly slidably mounted on the front and rear sides of the feed trough 1. A push plate 2 is slidably mounted inside the feed trough 1. A set of scrapers 12 are fixedly mounted on the left and right sides of the push plate 2. A first connecting plate 11 is fixedly mounted on the top of the push plate 2. The first wedges 13 are evenly fixedly mounted between the first connecting plate 11 and the internally threaded slider 17. A set of discharge ports is opened through the left and right sides of the feed trough 1. A sliding device is installed inside the discharge port. A sealing plate 19 is provided, and a second connecting plate 14 is fixedly installed on the top of the sealing plate 19. A set of second wedges 15 are fixedly installed on both the front and rear sides of the second connecting plate 14. The second wedges 15 correspond to the first wedges 13 and are located on the outside of the feed trough 1. The second connecting plate 14 and the first connecting plate 11 are both located on the top of the feed trough 1. When the screw 21 rotates, it will drive the internal thread slider 17 to move left and right. The internal thread slider 17 drives the first wedges 13 and the first connecting plate 11 to move left and right. When the first connecting plate 11 moves, it will drive the two sets of scrapers 12 to move left and right through the push plate 2. The movement scrapes the residue in the feed trough 1. Simultaneously, when the first wedge 13 moves and contacts the second wedge 15, it pushes the second wedge 15 upwards along the outer side of the first wedge 13. The discharge port penetrates the top of the feed trough 1. The top of the feed trough 1 has evenly spaced mounting holes, each fixed with a spring 25. A guide rod 24 is fixedly mounted on the top of the spring 25, and its top passes through the mounting hole and connects to the bottom of the second connecting plate 14. A set of support sleeves 23 is fixedly mounted on both the left and right sides of the bottom of the feed trough 1. The screw 21 is rotatably mounted within the two sets of support sleeves 23. A servo motor 22 is fixedly installed on the right side of the right support sleeve 23. The right side of the screw 21 is connected to the output end of the servo motor 22. The screw 21 is supported by the support sleeve 23 and rotated by the servo motor 22. A set of guide plates 18 are fixedly installed on both the left and right sides of the feed trough 1. The guide plates 18 correspond to the discharge port of the feed trough 1. The guide plates 18 are located outside the sealing plate 19. The servo motor 22 is located below the guide plates 18. Support feet 16 are evenly fixedly installed at the bottom of the feed trough 1. An installation cavity is opened inside the sealing plate 19. A configuration block 3 is fixedly installed in the installation cavity.

[0023] Working principle: The sealing plate 19 seals the feed trough, preventing feed from leaking out of the feed trough 1. The weight of the counterweight 3 and the elasticity of the spring 25 keep the sealing plate 19 stably positioned in the feed trough 1, making it difficult for the pig to push the sealing plate 19 open when it comes into contact with the pig while eating feed.

[0024] When residue cleaning is required, the servo motor 22 drives the screw 21 to rotate. When the screw 21 rotates, it drives the internal thread slider 17 to move left and right. The internal thread slider 17 drives the first wedge 13 and the first connecting plate 11 to move left and right. When the first connecting plate 11 moves, it drives the two sets of scrapers 12 to move left and right through the push plate 2, thereby scraping the residue in the feed trough 1. At the same time, when the first wedge 13 moves and comes into contact with the second wedge 15, it pushes the second wedge 15 along the outer edge of the first wedge 13. Sliding laterally upwards, the second wedge 15 drives the sealing plate 19 to slide upwards with the assistance of the guide rod 24 via the second connecting plate 14. When the second wedge 15 moves to the top of the first wedge 13, the sealing plate 19 is completely separated from the discharge port of the feed trough 1, and the scraper 12 pushes the residue out through the discharge port and falls onto the guide plate 18. The guide plate 18 prevents the residue from contacting the servo motor 22. When the residue is cleaned up and the push plate 2 is reset, the sealing plate 19 automatically moves downwards under the weight of the counterweight 3 and the rebound force of the spring 25 to close the discharge port.
