Description

Technical Field

[0001] This utility model relates to the field of chicken farming technology, specifically to a self-tensioning chicken coop manure scraping device. Background Technology

[0002] In modern poultry farming, large-scale chicken houses commonly employ manure belt cleaning systems to maintain a clean environment and reduce labor intensity. These systems use manure belts to collect chicken droppings and periodically move them to designated locations for cleaning. The scraper, a key component of the manure belt cleaning system, directly impacts the cleaning efficiency and overall farming effectiveness.

[0003] Existing technology includes a manure belt cleaning system for automated chicken farming, as disclosed in patent application number CN202221955314.3. In this system, the manure belt is fixed to a support roller and runs in the opposite direction via the support roller at the end. The reverse-running manure belt passes sequentially through a scraper device, a circulating roller brush cleaning device, and a cleaning roller brush cleaning device. The scraper device includes a scraper that contacts the manure belt and a blade holder that fixes the scraper at both ends. The circulating roller brush cleaning device and the cleaning roller brush cleaning device are identical, both including a brush roller that contacts the manure belt and a spray nozzle that sprays water onto the brush roller. This invention does not require modification to the manure belt path; it only requires adding a cleaning system, reducing conversion costs. It also provides good cleaning results, helping to maintain a healthy environment in the chicken coop. However, in this technical solution, the contact pressure between the scraper and the manure belt cannot be automatically adjusted or manually adjusted. When the manure belt experiences changes in tension, local deformation, or wear due to long-term use, the scraper cannot maintain a tight fit with the manure belt, easily resulting in incomplete scraping and manure residue.

[0004] In view of this, we propose a self-tensioning chicken coop manure scraping device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a self-tensioning chicken coop manure belt scraping device.

[0006] The technical solution of this utility model is:

[0007] A self-tensioning chicken coop manure scraping device includes a U-shaped frame fixed on a manure conveyor frame. A pressure plate is located below the U-shaped frame, and a movable frame is located below the pressure plate. A shovel is fixedly connected to the bottom of the front outer wall of the movable frame, with the bottom of the shovel fitting against the top of the manure belt. Two telescopic rods are symmetrically fixedly installed between the top of the movable frame and the bottom of the pressure plate. Several compression springs are fixedly installed between the top of the movable frame and the bottom of the pressure plate, with the compression springs located between the two telescopic rods. A first threaded shaft is fixedly connected to the center of the top of the pressure plate, passing through the U-shaped frame. An adjusting knob, threadedly connected to the first threaded shaft, is rotatably installed on the top of the U-shaped frame. By fixing a U-shaped frame to the manure belt conveyor and installing components such as a pressure plate, movable frame, shovel, telescopic rod, and compression spring, the elastic force of the compression spring allows the shovel to automatically adapt to the undulations and tension changes of the manure belt, always maintaining contact with the top of the manure belt to ensure effective scraping. Simultaneously, by adjusting the knob in its threaded engagement with the first threaded shaft, the height of the pressure plate can be adjusted, thereby adjusting the contact pressure between the shovel and the manure belt to adapt to different scraping needs under various working conditions, achieving a self-tensioning function and improving the applicability and reliability of the manure scraping device.

[0008] As a preferred technical solution, two guide shafts are symmetrically fixedly connected to the top of the pressure plate, and the guide shafts are inserted into the U-shaped frame. This guides the up-and-down movement of the pressure plate, preventing it from shifting or tilting during movement, and ensuring the stability and accuracy of the pressure plate's movement.

[0009] As a preferred technical solution, the telescopic rod consists of two sleeves that are nested together, and the two sleeves are fixedly connected to the pressure plate and the movable frame, respectively. Under the action of the compression spring, the telescopic rod can flexibly extend and retract according to the changes in the manure belt, effectively limiting the movement range of the movable frame and preventing it from deviating excessively.

[0010] As a preferred technical solution, a support plate is provided below the U-shaped frame, with the U-shaped frame and support plate located above and below the manure belt, respectively. This provides support for the manure belt, preventing it from sagging or deforming due to stress during the scraping process, ensuring stable operation of the manure belt, and enabling the scraper to more effectively remove manure, thereby improving scraping efficiency and quality.

[0011] As a preferred technical solution, each end of the U-shaped frame has a first extension plate integrally formed. A second threaded shaft is fixedly connected to the bottom of each first extension plate, and an adjusting nut is threaded onto each second threaded shaft. The second threaded shaft passes through a support plate, and the adjusting nut is located below the support plate. By turning the adjusting nut, the distance between the U-shaped frame and the support plate can be easily adjusted, thereby adjusting the tension of the manure belt, ensuring a good fit between the manure scraping device and the manure belt, and improving the versatility and practicality of the device.

[0012] As a preferred technical solution, each end of the support plate has a second extension plate integrally formed thereon, and two second threaded shafts pass through the two second extension plates respectively. The adjusting nut is rotatably installed at the bottom of the second extension plate. This facilitates adjustment of the distance between the U-shaped frame and the support plate.

[0013] As a preferred technical solution, the top of the support plate is provided with a mounting groove, and a plurality of equally spaced rollers are rotatably mounted in the mounting groove. The rollers in the mounting groove at the top of the support plate can reduce the friction between the manure belt and the support plate, making the manure belt run more smoothly during operation, reducing wear on the manure belt, and extending the service life of the manure belt.

[0014] As a preferred technical solution, a vertical strip-shaped limiting groove is formed on the outer wall of the first threaded shaft, and a limiting block is integrally formed inside the U-shaped frame, which is slidably connected to the strip-shaped limiting groove. The limiting block and the strip-shaped limiting groove can restrict the rotation of the first threaded shaft, so that it can only move up and down in the vertical direction.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention fixes a U-shaped frame to the manure belt conveyor and includes components such as a pressure plate, a movable frame, a shovel, a telescopic rod, and a compression spring. Utilizing the elastic force of the compression spring, the shovel automatically adapts to the rise and fall and tension changes of the manure belt, maintaining constant contact with the top of the belt to ensure effective scraping. Simultaneously, by adjusting the knob in its threaded engagement with the first threaded shaft, the height of the pressure plate can be adjusted, thereby regulating the contact pressure between the shovel and the manure belt. This adapts to different scraping requirements under various working conditions, achieving a self-tensioning function and improving the applicability and reliability of the scraping device.

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.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] The self-tensioning chicken coop manure scraping device includes a U-shaped frame 1 fixed on the manure conveyor frame. A pressure plate 10 is provided below the U-shaped frame 1, and a movable frame 15 is provided below the pressure plate 10. A shovel 17 is fixedly connected to the bottom of the front outer wall of the movable frame 15. The bottom of the shovel 17 is in contact with the top of the manure belt. Two telescopic rods 113 are symmetrically fixed between the top of the movable frame 15 and the bottom of the pressure plate 10. Several compression springs 16 are fixedly installed between the top of the movable frame 15 and the bottom of the pressure plate 10. The compression springs 16 are located between the two telescopic rods 113. A first threaded shaft 11 is fixedly connected to the center of the top of the pressure plate 10. The first threaded shaft 11 passes through the U-shaped frame 1, and an adjustment knob 13 that is threadedly connected to the first threaded shaft 11 is rotatably installed on the top of the U-shaped frame 1. By fixing a U-shaped frame 1 to the manure belt conveyor and installing components such as a pressure plate 10, a movable frame 15, a shovel 17, a telescopic rod 113, and a compression spring 16, the elastic force of the compression spring 16 allows the shovel 17 to automatically adapt to the height and tension changes of the manure belt, always maintaining contact with the top of the manure belt to ensure effective scraping. At the same time, by adjusting the threaded engagement between the knob 13 and the first threaded shaft 11, the height of the pressure plate 10 can be adjusted, thereby adjusting the contact pressure between the shovel 17 and the manure belt to adapt to the scraping needs under different working conditions, achieving a self-tensioning function and improving the applicability and reliability of the manure scraping device.

[0026] It should be added that the U-shaped frame 1 has two fixed plates 111 integrally formed symmetrically at both ends, and each fixed plate 111 has a fixing hole 112.

[0027] In a preferred embodiment, two guide shafts 12 are symmetrically fixedly connected to the top of the pressure plate 10, and the guide shafts 12 are inserted into the U-shaped frame 1. This guides the up-and-down movement of the pressure plate 10, preventing the pressure plate 10 from shifting or tilting during movement, and ensuring the stability and accuracy of the movement of the pressure plate 10.

[0028] In a preferred embodiment, the telescopic rod 113 consists of two sleeves that are nested together, and the two sleeves are fixedly connected to the pressure plate 10 and the movable frame 15, respectively. Under the action of the compression spring 16, the telescopic rod 113 can flexibly extend and retract with the change of the manure belt, effectively limiting the movement range of the movable frame 15 and preventing it from deviating excessively.

[0029] In a preferred embodiment, a support plate 2 is provided below the U-shaped frame 1, with the U-shaped frame 1 and the support plate 2 located above and below the manure belt, respectively. This provides support for the manure belt, preventing it from sagging or deforming due to force during the scraping process, ensuring stable operation of the manure belt, and enabling the scraper 17 to scrape manure more effectively, thereby improving scraping efficiency and quality.

[0030] In a preferred embodiment, each end of the U-shaped frame 1 has an integrally formed first extension plate 18. A second threaded shaft 19 is fixedly connected to the bottom of each first extension plate 18, and an adjusting nut 110 is threaded onto each second threaded shaft 19. The second threaded shaft 19 passes through the support plate 2, and the adjusting nut 110 is located below the support plate 2. By turning the adjusting nut 110, the distance between the U-shaped frame 1 and the support plate 2 can be easily adjusted, thereby adjusting the tension of the manure belt, ensuring a good fit between the manure scraping device and the manure belt, and improving the versatility and practicality of the device.

[0031] In a preferred embodiment, each end of the support plate 2 is integrally formed with a second extension plate 22, and two second threaded shafts 19 pass through the two second extension plates 22 respectively. An adjusting nut 110 is rotatably mounted on the bottom of the second extension plate 22. This facilitates adjustment of the distance between the U-shaped frame 1 and the support plate 2.

[0032] In a preferred embodiment, the support plate 2 has a mounting groove 20 at its top, and a plurality of equally spaced rollers 21 are rotatably mounted in the mounting groove 20. The rollers 21 in the mounting groove 20 at the top of the support plate 2 can reduce the friction between the manure belt and the support plate 2, making the manure belt run more smoothly during operation, reducing wear on the manure belt, and extending the service life of the manure belt.

[0033] In a preferred embodiment, a vertical strip-shaped limiting groove 14 is provided on the outer wall of the first threaded shaft 11, and a limiting block is integrally formed inside the U-shaped frame 1, which is slidably connected to the strip-shaped limiting groove 14. The limiting block and the strip-shaped limiting groove 14 can restrict the rotation of the first threaded shaft 11, so that it can only move up and down in the vertical direction.

[0034] When using the self-tensioning chicken coop manure scraper of this utility model:

[0035] When the manure belt is running on the conveyor frame, the U-shaped frame 1 fixed to the conveyor frame and the manure scraping assembly below it work synchronously. The compression spring 16 between the pressure plate 10 and the movable frame 15 provides elastic force, ensuring that the scraper 17 at the bottom of the movable frame 15 is always in contact with the surface of the manure belt to scrape off the manure. When the manure belt experiences changes in tension or unevenness, the compression spring 16 will extend or retract accordingly, causing the movable frame 15 to move up and down along the telescopic rod 113, automatically adjusting the contact pressure between the scraper 17 and the manure belt, thus achieving a self-tensioning function. The telescopic rod 113 consists of a sleeve, ensuring stable movement of the movable frame 15 and preventing excessive deviation. At the same time, by adjusting the threaded engagement between the knob 13 and the first threaded shaft 11, the height of the pressure plate 10 can be adjusted, thereby adjusting the contact pressure between the scraper 17 and the manure belt.

[0036] The guide shaft 12 at the top of the pressure plate 10 is inserted into the U-shaped frame 1 to ensure that the pressure plate 10 moves vertically and avoids uneven scraping of manure due to tilting. The U-shaped frame 1 and the support plate 2 are connected by the second threaded shaft 19 and the adjusting nut 110. Rotating the adjusting nut 110 can adjust the distance between the two, thereby tensioning the manure belt to adapt to different working conditions. The roller 21 on the support plate 2 reduces the frictional resistance of the manure belt during operation, reduces energy consumption, and extends the service life of the manure belt.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
