[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] The utility model provides a kind of poultry house inside the implementation example of secondary manure cleaning device in front end of manure conveying: as Figure 1 As shown in Figure 2 It includes the upper scraper 1 between the breeding cage 10 and the manure cleaning main machine 11, the upper scraper 1 is fixedly connected with the side plate 2, the number of side plate 2 is two, the breeding cage 10 and the manure cleaning main machine 11 are fixedly connected with the connecting frame 12, and the upper scraper 1 is fixedly connected on the connecting frame 12 by the side plate 2.

[0025] As shown in Figure 2 And Figure 3 The lower scraper 3 parallel to the length direction of the upper scraper 1 is movably connected on the side plate 2, for scraping manure on the lower surface of the manure conveying belt 13, the lower scraper 3 is arranged between the two side plates 2, and the edge side of the lower scraper 3 along the length direction is tightly combined with the lower surface of the manure conveying belt 13. When the manure conveying belt 13 is annularly operated, the lower surface of the manure conveying belt 13 moves along the edge of the lower scraper 3, and in this process, the lower scraper 3 can scrape the manure adhered to the lower surface of the manure conveying belt 13, so as to ensure the effectiveness of scraping manure on the outer surface of the manure conveying belt 13.

[0026] As shown in Figure 4As shown, the device also includes a connecting plate 6 parallel to the length direction of the lower scraper 3, the connecting plate 6 is provided with a connecting shaft 7, and the connecting plate 6 is rotatably installed on the side plate 2 through the connecting shaft 7, and the lower scraper 3 is detachably installed on the connecting plate 6;

[0027] As shown in the drawings, Figure 5 As shown, Figure 6 As shown, the lower scraper 3 and the connecting plate 6 are provided with a bolt 9, and the lower scraper 3 is installed on the connecting plate 6 through the bolt 9. Through the detachable design, when the lower scraper 3 needs to be overhauled, the lower scraper 3 can be directly removed by unscrewing the bolt 9, so that the later maintenance and replacement of the lower scraper 3 will be more convenient. Moreover, the lower scraper 3 is made of PVC material, which not only facilitates processing, but also reduces processing costs. Therefore, the production and use costs of the device can be reduced to a certain extent.

[0028] The lower scraper 3 is connected with the side plate 2 through a tension spring 4, one end of the tension spring 4 close to the lower scraper 3 is connected with the connecting plate 6, and the outer side of the side plate 2 is fixedly connected with a fixed plate 8, the fixed plate 8 is provided with a tension pin shaft 5, and the other end of the tension spring 4 is connected with the tension pin shaft 5;

[0029] As shown in the drawings, Figure 6 As shown, after the device is installed, the upper scraper 1 is located between the upper and lower layers of the manure conveying belt 13, the connecting plate 6 and the lower scraper 3 are located below the lower layer of the manure conveying belt 13, and the connecting plate 6 and the lower scraper 3 are inclined at a certain angle. Therefore, the upper edge of the lower scraper 3 is in contact with the lower surface of the lower layer of the manure conveying belt 13, and under the tension of the tension spring 4, the connecting plate 6 and the lower scraper 3 can be subjected to a clockwise rotation trend along the axis of the connecting shaft 7, so that the lower scraper 3 can be in close contact with the manure conveying belt 13;

[0030] Moreover, due to the elasticity of the tension spring 4, when the manure conveying belt 13 falls to a certain extent under the action of gravity, the connecting plate 6 and the lower scraper 3 will also deflect counterclockwise around the axis of the connecting shaft 7 by a certain angle, and when the falling degree of the manure conveying belt 13 decreases, the connecting plate 6 and the lower scraper 3 will be pulled clockwise along the axis of the connecting shaft 7 by a certain angle under the tension of the tension spring 4. Therefore, the lower scraper 3 can be self-adaptively adjusted according to the falling degree of the manure conveying belt 13, so as to ensure that the lower scraper 3 and the manure conveying belt 13 can always maintain effective contact, thereby ensuring the effectiveness of scraping and cleaning, while avoiding the contact between the lower scraper 3 and the manure conveying belt 13 being too tight, thereby preventing serious wear and tear and ensuring the service life of the device.

[0031] Working principle: The poultry manure produced inside the cage 10 falls onto the manure conveyor belt 13 below, and the power system on the manure cleaning unit 11 drives the manure conveyor belt 13 to rotate (rotation direction as follows). Figure 6 (As indicated by the middle arrow) and thus transport the manure to the manure cleaning host 11. When it is transported to the end of the manure conveyor belt 13, it will be cleaned and collected for the first time by the scraping device in the manure cleaning host 11. After the manure is unloaded from the upper layer of the manure conveyor belt 13, it is moved to the lower layer. When it runs to the lower scraper 3, the lower scraper 3 can scrape and clean the lower surface of the manure conveyor belt 13 again. The scraped manure falls down under the action of gravity and is collected by the external collection device, thus achieving the purpose of secondary scraping and cleaning. This ensures that the manure conveyor belt 13 is cleaned before it returns to the bottom of the breeding cage 10, thereby effectively preventing the manure from being transported back to the breeding cage 10 and thus effectively preventing the manure from falling back into the breeding cage 10.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
