Description

Technical Field

[0001] This utility model relates to the technical field of manure cleaning, and in particular to a manure backflushing system applied to ranches. Background Technology

[0002] With the development of animal husbandry, many ranches in China have gradually come into the public eye. Currently, in cattle sheds on these ranches, manure cleaning mainly relies on manual labor, using tools such as shovels and push shovels. These methods are not only time-consuming but also labor-intensive and inefficient. Workers often become covered in dirt and are extremely tired during the cleaning process. Therefore, some ranches have adopted a flushing method to clean the manure.

[0003] For example, Chinese utility model patent CN206744163U discloses a sewage flushing system, including a flushing pump, a main flushing pipe, flushing branch pipes, a cleaning pump, a main cleaning pipe, cleaning branch pipes, several flushing heads, an infrared sensor, and a controller. The infrared sensor is used to sense sewage and is connected to the controller via a signal connection. The controller receives the signal from the infrared sensor and controls the opening and closing of the flushing and cleaning pumps. It can automatically open the flushing and cleaning pumps to flush the sewage, thereby achieving the purpose of cleaning, avoiding sewage pollution, and saving water resources.

[0004] However, when the inventors implemented this device, they found the following drawbacks: for large ranches, the flushing and cleaning method consumes a lot of water resources and increases the amount of wastewater to be treated, which undoubtedly increases the operating costs of the ranch.

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.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model discloses a manure backwashing system for ranches, comprising a mobile chassis 1, a manure scraping mechanism mounted on the mobile chassis 1, a screw conveyor 2, a dewatering machine, a water tank 3, and a flushing assembly. The manure scraping mechanism scrapes manure from the ground towards the inlet of the screw conveyor 2. The outlet of the screw conveyor 2 is connected to the inlet of the dewatering machine, and the liquid phase outlet of the dewatering machine is connected to the interior of the water tank 3. The flushing assembly includes a pressure pump 4 and a flushing pipe assembly 5. The input end of the pressure pump 4 extends into the water tank 3, and the output end of the pressure pump 4 is connected to the input end of the flushing pipe assembly 5.

[0027] The manure backwashing system provided in this embodiment can replenish clean water to the water tank 3 in a timely manner through the water supply pipe 28 to meet the water demand for ground washing. When scraping off manure, the first telescopic cylinder 9 extends or retracts, causing the swing arm 7 to swing, and the second telescopic cylinder 10 extends or retracts, causing the scraper 8 to rotate. This can greatly increase the swing area of ​​the scraper 8, thereby increasing the range of manure removal from the ground. When washing the ground, the reciprocating swing of the scraper 8 can improve the washing effect of the high-pressure water jet sprayed from the flushing pipe group 5 on the dirt on the ground.

[0028] Example 2

[0029] For details, please refer to Figure 3 The dewatering machine includes a frame 11, a conical shell 12 mounted on the frame 11, a roller 13 rotatably mounted on the frame 11, a first motor 14 providing power for the rotation of the roller 13, a sealing plate 15 slidably mounted on the roller 13, and two third telescopic cylinders 16. The roller 13 is equipped with conical spiral extrusion blades 17 that fit into the inner wall of the conical shell 12. An annular discharge channel is formed between the roller 13 and the small-diameter discharge end of the conical shell 12. The sealing plate 15 is used to block the annular discharge channel. The third telescopic cylinders 16 provide power for the movement of the sealing plate 15. The bottom of the conical shell 12 is provided with multiple leakage holes 18. The water tank 3 is an open water tank 3, and the leakage holes 18 are located above the water tank 3. Furthermore, the third telescopic cylinder 16 is fixedly mounted on the frame 11, and the sealing plate 15 is fixedly mounted on the output end of the third telescopic cylinder 16.

[0030] For details, please refer to Figure 4 It also includes a mixing housing 19 mounted on a mobile chassis 1. A rotating shaft 20 is rotatably mounted inside the mixing housing 19. A crushing auger 21 and a spiral conveyor blade 22 are provided on the rotating shaft 20. The mixing housing 19 is provided with a discharge port 23 facing downwards. The mixing housing 19 is located below the annular discharge channel. Furthermore, the crushing auger 21 is mounted on the rotating shaft 20 near the annular discharge channel.

[0031] For details, please refer to Figure 2 A feeding hopper 25 is installed above the frame 11, and the discharge end of the feeding hopper 25 is located above the mixing shell 19.

[0032] For details, please refer to Figure 1 A support frame 26 is installed on the mobile chassis 1, and the frame 6 is slidably installed on the support frame 26. A fourth telescopic cylinder 27 is installed on the mobile chassis 1 to provide power for the sliding of the frame 6. Furthermore, a guide slide rod is provided on the support frame 26, and the frame 6 is slidably installed on the guide slide rod.

[0033] The manure flushing system for ranches provided in this embodiment initially blocks the annular discharge channel with a baffle plate 15, allowing manure to enter the conical shell 12. A first motor 14 drives the roller shaft 13 and the conical spiral extrusion blades 17 to rotate. Under the action of the conical spiral extrusion blades 17, the manure is gradually compressed, and the resulting liquid phase enters the water tank 3 through the leakage hole 18. After the water in the manure is squeezed out, a third telescopic cylinder 16 moves the baffle plate 15, disengaging it from the annular discharge channel. The dried manure then enters the mixing shell 19, followed by a second motor 24 driving the rotating shaft. The shaft 20 rotates, and the rotating shaft 20 drives the crushing scissors 21 to rotate. The crushing scissors 21 crushes the dry manure. Under the action of the screw conveyor blades 22, the dry manure is pushed to the discharge port 23. The dry manure is washed and falls to the cleaned ground through the discharge port 23. This part of the dry manure is used to lay the bedding in the cattle shed. Rice husks and lime powder can be put into the mixing shell 19 through the feeding hopper 25 in a certain proportion, so that the rice husks and lime powder are mixed with the dry manure and used to lay the bedding in the cattle shed, replacing the traditional rice husk bedding. The effective use of dry manure reduces the workload of the drying yard.

[0034] When spreading dry manure, rice husks and quicklime powder, the fourth telescopic cylinder 27 is activated to move the frame 6 upward, thereby changing the distance between the scraper 8 and the ground. The scraper 8 is used to level the mixture of dry manure, rice husks and quicklime powder, thus allowing for adaptive adjustment of the bed thickness. Furthermore, the use of the scraper 8 enables rapid spreading of the bed, further reducing manual labor and improving the efficiency of bed spreading.

[0035] During use, the scraper mechanism pushes the manure towards the feed inlet of the screw conveyor 2 as the mobile chassis 1 moves. The screw conveyor 2 then transports the manure to the dewatering machine for dehydration. The wastewater generated by the dewatering machine enters the water tank 3. When the ground needs to be cleaned, the pressure pump 4 draws the wastewater from the water tank 3 and discharges it through the flushing pipe assembly 5 to flush the ground. After flushing, the dehydrated dry manure enters the mixing shell 19. An appropriate proportion of rice husks and quicklime powder are added to the mixing shell 19 through the feeding hopper 25. The second motor 24 starts and crushes the dry manure through the crushing auger 21, causing the dry manure, rice husks, and quicklime powder to mix together. The mixed material is then conveyed to the discharge port 23 by the screw conveyor blade 22 and falls to the ground. The distance between the scraper 8 and the ground is adjusted, and the scraper 8 is used to spread the mixture to form the bedding required for the cattle shed.
