For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.

[0028] As Figure 1-7 shown, a pigsty floor cleaning device proposed by the present utility model includes a bottom plate 1. Universal wheels 2 are provided at the four corners of the bottom of the bottom plate 1. A push handle 3 is provided on the top of the bottom plate 1. A cleaning structure 4 is arranged on the top of the bottom plate 1, and a spraying structure 5 is arranged on the top of the bottom plate 1.

[0029] In the present utility model, the universal wheels 2 and the push handle 3 facilitate the staff to move the bottom plate 1, the cleaning structure 4 and the spraying structure 5. And through the spraying structure 5, a mixed liquid of clear water and cleaning agent can be sprayed on the pigsty floor, and the sprayed floor is cleaned through the cleaning structure 4.

[0030] In an optional embodiment, the cleaning structure 4 includes a fixed box 41, a threaded sleeve 42, a driving component 43, a threaded rod 44, a lifting plate 45, two guide rods 46, a compression component 47, two groups of brushing components 48 and a scraping shovel 49. The fixed box 41 is arranged on the top of the bottom plate 1.

The scraping shovel 49 is arranged at the bottom of the lifting plate 45.

[0031] It should be noted that the driving component 43 can make the threaded sleeve 42 rotate. Under the action of the two guide rods 46, the compression component 47 will not rotate, so that the threaded rod 44 will not rotate. When the threaded sleeve 42 rotates, under the action of the threaded thrust, the threaded sleeve 42 will drive the threaded rod 44 to move up or down. The threaded rod 44 will drive the compression component 47 to move up or down. The compression component 47 will drive the lifting plate 45 to move up or down. The lifting plate 45 will drive the two groups of brushing components 48 and the scraping shovel 49 to move up or down.

[0032] Among them, when the two groups of scrubbing components 48 and the scraping shovel 49 move downward, the two groups of scrubbing components 48 and the scraping shovel 49 can be brought into contact with the ground. The ground of the pigsty is scrubbed by the two groups of scrubbing components 48, and the dirt scrubbed is scraped and collected by the scraping shovel 49. When the two groups of scrubbing components 48 and the scraping shovel 49 move upward, the scrubbing components 48 and the scraping shovel 49 can be separated from the ground. At this time, it is convenient to move the entire cleaning device.

[0033] In an alternative embodiment, the driving assembly 43 includes a driving servo motor 431, a rotating shaft 432, a driving bevel gear 433, and a driven bevel gear 434. The driving servo motor 431 is disposed on the right side of the fixed box 41. The rotating shaft 432 is disposed on the output shaft of the driving servo motor 431 and extends into the interior of the fixed box 41. The driving bevel gear 433 is disposed at the left end of the rotating shaft 432. The driven bevel gear 434 is disposed on the outer side of the threaded sleeve 42.

[0034] It should be noted that when the driving servo motor 431 is started, the output shaft of the driving servo motor 431 will drive the rotating shaft 432 to rotate. The rotating shaft 432 will drive the driving bevel gear 433 to rotate. The driving bevel gear 433 will drive the driven bevel gear 434 meshing therewith to rotate. The driven bevel gear 434 will drive the threaded sleeve 42 to rotate.

[0035] In an alternative embodiment, the compression assembly 47 includes a fixed block 471, a sliding groove 472, a movable block 473, and a plurality of compression springs 474.

The bottoms of the plurality of compression springs 474 are all connected to the top of the movable block 473. The top of the fixed block 471 is connected to the bottoms of the two guide rods 46. The bottom of the movable block 473 is connected to the top of the lifting plate 45.

[0036] It should be noted that when the two groups of scrubbing components 48 and the scraping shovel 49 are in contact with the ground, it is possible that the downward movement amplitude of the two groups of scrubbing components 48 and the scraping shovel 49 is too large. At this time, the ground will squeeze the two groups of scrubbing components 48 and the scraping shovel 49, causing the lifting plate 45 to move upward. The lifting plate 45 will cause the movable block 473 to move upward, causing the movable block 473 to squeeze the plurality of compression springs 474 inside the sliding groove 472. Through the resilience of the plurality of compression springs 474, the two groups of scrubbing components 48 and the scraping shovel 49 are brought into full contact with the ground, avoiding the situation of being separated from the ground during the movement and use of the cleaning device.
