Description

Technical Field

[0001] This utility model relates to the field of livestock feeders, specifically to a self-cleaning pig feeder. Background Technology

[0002] In pig farming, when feeding pigs, the feed is usually put into a feeder, and then the pigs are driven to the sides of the feeder to eat, thus completing the feeding process.

[0003] A search revealed a patent application with application number 202323445824.3 that discloses a feeder for pig farming. This feeder is equipped with an automatic cleaning mechanism. When water in the storage tank is sprayed onto the feed flow trough, the clean water washes away some of the residual feed. At the same time, the cleaning brush moves to the right to sweep away the residual feed adhering to the inner wall of the feed flow trough, thus preventing residual feed from adhering to the inner wall of the feed flow trough and improving the cleaning effect.

[0004] However, when the automatic cleaning mechanism of the aforementioned feeder cleans the inner wall of the feed flow trough, residual feed often remains on the cleaning brush. Although it can be cleaned by spraying water from the storage tank, on the one hand, the feed stored in the storage tank must be emptied before water is added, which is cumbersome, time-consuming, and labor-intensive. On the other hand, the water spray position of the storage tank is fixed. As the cleaning brush moves, it gradually moves away from the discharge pipe of the storage tank. At this time, the water sprayed from the storage tank is often insufficient to effectively rinse the cleaning brush, and feed remains on the cleaning brush. As a result, the cleaning brush cannot effectively clean the feed flow trough, leading to poor cleaning effect and hindering the subsequent use of the feed flow trough. Utility Model Content

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1-10 As shown, a self-cleaning pig feeder includes a base frame 1, a feeding trough 2 and a storage tank 4 installed on the base frame 1. The storage tank 4 is used to supply feed to the feeding trough 2. The feeding trough 2 is equipped with a self-cleaning mechanism 5 for cleaning its interior, and a waste discharge valve 3 is also installed at one end of the feeding trough 2. The base frame 1 is also equipped with a controller (not shown in the figure) for convenient operation of various electrical components in the feeder. The controller can be a conventional PLC controller currently on the market, and the specific model is not limited here.

[0036] The self-cleaning mechanism 5 includes a scraper 54 located inside the feeding trough 2. The scraper 54 is connected to a drive unit that drives it to reciprocate along the inside of the feeding trough 2. The drive unit includes a frame 51 fixed to the top of the base frame 1 and a movable frame 52 located inside the feeding trough 2. The inner wall of the frame 51 has mounting cavities on both sides, and a lead screw 55 and a guide rod 56 are respectively installed in the two mounting cavities. A lead screw seat 511 that cooperates with the lead screw 55 is installed on one side of the movable frame 52, and a slider that is slidably sleeved on the guide rod 56 is fixed on the other side. The lead screw seat 511 and the slider are both located in the mounting cavity. The scraper 54 is installed on the movable frame 52. A motor 53 that drives the lead screw 55 to rotate is also installed on one side of the frame 51.

[0037] It also includes a rinsing structure 6, which includes a water sprayer inside the feeding trough 2, a water storage tank 61 and a pump body 62 on the base frame 1. The outlet end of the pump body 62 is connected to a liquid delivery pipe 63, and the inlet end is connected to the water storage tank 61 through a pipe. One end of the liquid delivery pipe 63 is connected to a diversion hose 64 connected to the water sprayer, and the water sprayer can move synchronously with the cleaning scraper 54 along the inside of the feeding trough 2.

[0038] In this embodiment, regarding the aforementioned water spray component, as follows: Figure 1 , Figure 2 , Figures 5-7 as well as Figure 9 and Figure 10 As shown, the water spraying component includes two nozzles 65 installed on one side of the movable frame 52. The two nozzles 65 are symmetrically distributed on both sides of the cleaning scraper 54, and the bottom ends of the two nozzles 65 are connected to water spray pipes 66. The water outlets of the two water spray pipes 66 are both facing the cleaning side of the cleaning scraper 54.

[0039] In pig farming, feed for feeding pigs can be stored in the storage tank 4 in advance. When feeding pigs, feed can be added into the feeding trough 2 through the storage tank 4. Then, the pigs are driven to both sides of the feeding trough 2 for the pigs to eat until the feeding is completed.

[0040] After feeding, the motor 53 drives the lead screw 55 to rotate, which in turn drives the moving frame 52 to move through the lead screw seat 511. The moving frame 52 then drives the cleaning scraper 54 to move along the inside of the feeding trough 2. At this time, the slider on the other side of the moving frame 52 slides along the guide rod 56 to limit the moving frame 52 and ensure that the moving frame 52 drives the cleaning scraper 54 to move stably to clean the residual food inside the feeding trough 2. Then, the waste discharge valve 3 is opened to discharge the residual food in the feeding trough 2, thereby realizing the self-cleaning of the feeding trough 2. After the feeding trough 2 is self-cleaned, the motor 53 drives the lead screw 55 to rotate in the opposite direction, which causes the moving frame 52 to move and reset the cleaning scraper 54 for subsequent feeding.

[0041] Meanwhile, while the scraper 54 is cleaning the inside of the feeding trough 2, the water in the water storage tank 61 can be pumped out by the pump body 62 and then delivered into the water spraying device through the liquid delivery pipe 63 and the diversion hose 64. The water spraying device then sprays the water onto the side wall of the scraper 54 to rinse the cleaning side of the scraper 54, preventing food from adhering to the cleaning side of the scraper 54. This allows for simultaneous scraping and rinsing of the inside of the feeding trough 2, improving the cleaning effect of the feeding trough 2 and ensuring its subsequent use.

[0042] In this embodiment, regarding the aforementioned storage tank 4, as follows: Figures 1-3 As shown, the storage tank 4 includes a tank body 41, with a discharge pipe 43 connected to the bottom end of the tank body 41 and a detachable top cover 45 provided at the top. A feeding pipe 44 is installed on the top cover 45. A fixing frame 42 for installing the tank body 41 is welded to one side of the base frame 1. Specifically, a valve is installed on the discharge pipe 43.

[0043] When in use, feed can be added into the tank 41 through the feed pipe 44, and then the valve can be opened to allow the feed in the tank 41 to be discharged into the feeding trough 2 through the discharge pipe 43 for the pigs to eat. When cleaning the inside of the tank 41, the top cover 45 can be opened to clean the inside of the tank 41, and then the feed can be discharged through the discharge pipe 43 to clean the tank 41, prevent the accumulation of dirt inside the tank 41, and ensure the subsequent use of the tank 41.

[0044] In another embodiment, such as Figure 1 , Figure 2 ,as well as Figures 4-10 As shown, a U-shaped groove for installing the cleaning scraper 54 is provided on one side of the movable frame 52. Limiting blocks 510 are fixed on both sides of the inner wall of the U-shaped groove, and fastening screws 513 are screwed onto both limiting blocks 510. The cleaning scraper 54 is provided with a limiting groove 57 that cooperates with the limiting blocks 510, and the cleaning scraper 54 is also provided with a screw hole 59 that cooperates with the fastening screw 513.

[0045] When the scraper 54 needs to be disassembled, the fastening screw 513 can be unscrewed from the screw hole 59 first, and then the scraper 54 can be pulled upwards to pull it out of the U-shaped groove on the moving frame 52. The scraper 54 can then be removed from the moving frame 52. After that, the scraper 54 can be cleaned or replaced. After cleaning or replacing, the scraper 54 can be inserted into the U-shaped groove until the limiting block 510 is inserted into the limiting groove 57. Then, the fastening screw 513 can be screwed into the screw hole 59 to fix the scraper 54. This completes the installation of the scraper 54, thereby enabling quick disassembly and assembly of the scraper 54, facilitating the cleaning or replacement of the scraper 54, and thus ensuring the normal use of the scraper 54 and enabling rapid cleaning of the inside of the feeding trough 2.

[0046] Furthermore, such as Figures 4-10 As shown, a positioning pin 512 is installed on the top of the limiting block 510, and a positioning hole 58 corresponding to the positioning pin 512 is opened on the top of the cleaning scraper 54.

[0047] When the scraper 54 is inserted into the U-shaped groove and the limiting block 510 is inserted into the limiting groove 57, the positioning pin 512 can be inserted into the positioning hole 58 to limit the distance between the scraper 54 and the moving frame 52, thereby ensuring the stable installation of the scraper 54 and facilitating the rapid cleaning of the inside of the feeding trough 2 by the scraper 54.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
