The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a cow manure composting mixing device includes: a mixing drum 20, which is a hollow cylinder with a crescent-shaped opening at the top. A mixing motor 21 is fixedly connected to the top of the mixing drum 20, and the mixing motor 21 is electrically connected to a corresponding power source. This is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a reciprocating structure is installed on the wall of the mixing drum 20 to shake the mixing drum 20. The reciprocating structure includes: a support 30, a rotating wheel 34, a toothed rail 35, an electric cylinder 40, a sleeve 41, and a stirring rod 44. The support 30 is installed on both sides of the mixing drum 20, the rotating wheel 34 is installed at the rear of the mixing drum 20, the toothed rail 35 is fixedly connected to the bottom of the mixing drum 20, the electric cylinder 40 is rotatably connected to the top of the cavity of the mixing drum 20, and the stirring rod 44 is fixedly connected to the bottom of the electric cylinder 40. The mixing drum 20 can shake between the symmetrical supports 30.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the support 30 is an inverted T-shaped plate, and the bottom of the symmetrical supports 30 are connected by rectangular rods. The rotating wheel 34 is gear-shaped, and the toothed rail 35 is an arc-shaped rod. The inner arc surface of the toothed rail 35 is fixedly connected to the wall of the stirring drum 20 by two rectangular plates. The inner arc surface of the toothed rail 35 can be aligned with the bottom and rear wall of the stirring drum 20. The outer arc surface of the toothed rail 35 has teeth that can mesh with the rotating wheel 34. The stirring motor 21 can drive the electric cylinder 40 to rotate. The sleeve 41 is a hollow rectangular tube with an open top and a closed bottom. The sleeve 41 can be fitted onto the outer wall of the electric cylinder 40. The bottom end of the electric cylinder 40 can be fixedly connected to the bottom of the sleeve 41 cavity. The stirring rod 44 is a rhomboid cross-section rod. Multiple stirring rods 44 are arranged in a ring array around the sleeve 41. The reciprocating structure also includes a limiting shaft 31, a rear frame 32, a servo motor 33, and a base plate 42. Support rods 43 and limiting shafts 31 are symmetrically fixedly connected on both sides of the mixing drum 20. The symmetrical limiting shafts 31 can be inserted into the side wall of the support 30 on each side. The rear frame 32 is fixedly connected to the rear wall of each support 30. There is a gap between the symmetrical rear frames 32. The servo motor 33 is fixedly connected to the wall of the rear frame 32 on one side. The rotating wheel 34 is rotatably connected between the symmetrical rear frames 32. The servo motor 33 can drive the rotating wheel 34 to rotate. The bottom plate 42 is fixedly connected to the bottom of the sleeve 41. Support rods 43 are fixedly connected to the wall of the bottom plate 42. The stirring rod 44 is fixedly connected to the side wall of the support rod 43. The rear frame 32 is an L-shaped rod. The bottom plate 42 is a triangular block. The same support rods 43 are respectively set on the three sides of the bottom plate 42. The support rods 43 are capsule-shaped rods. Three identical stirring rods 44 are linearly arrayed on the side wall of each support rod 43.

[0030] In practical use, firstly, pour the required amount of cow manure compost into the cavity of the mixing drum 20 through the opening at the top of the mixing drum 20. Then, turn on the power. When the power is turned on, the mixing motor 21 and the servo motor 33 will be energized simultaneously. The mixing motor 21 can drive the electric cylinder 40 to rotate, and the electric cylinder 40 can also be energized. When driven by the mixing motor 21, the electric cylinder 40 rotates within the cavity of the mixing drum 20. When the electric cylinder 40 rotates, it will drive the sleeve 41, the base plate 42, the support rod 43, the mixing rod 44, the shovel block 45, and the scraper 46 to rotate simultaneously within the cavity of the mixing drum 20. The rotating mixing rod 44 can stir the cow manure compost within the cavity of the mixing drum 20. During rotation, the electric cylinder 40 can also reciprocate in length. The sleeve 41, base plate 42, support rod 43, stirring rod 44, shovel block 45 and scraper 46 can change their horizontal height as the electric cylinder 40 retracts. When the servo motor 33 drives the rotating wheel 34 to rotate, the rotating wheel 34 can drive the toothed rail 35 to rotate around the limiting axis 31 by meshing with the toothed rail 35. When the toothed rail 35 rotates, it will drive the mixing drum 20 to shake synchronously. After the cow manure compost in the mixing drum 20 is mixed, the toothed rail 35 drives the mixing drum 20 to be in a horizontal position by the rotation of the rotating wheel 34. At this time, the cow manure compost in the mixing drum 20 will be discharged from the opening at the top of the mixing drum 20.

[0031] In summary, by setting up a reciprocating structure to drive the mixing drum 20 to reciprocate and swing back and forth, and in conjunction with the electric cylinder 40 driving the mixing rod 44, the cow manure in the mixing drum 20 cavity is reciprocated axially and longitudinally, thereby making this solution highly efficient in mixing cow manure for composting.

[0032] like Figure 4 and Figure 5 As shown, the wall of the stirring rod 44 is provided with an auxiliary structure, which includes a shovel block 45 and a scraper 46. The shovel block 45 is fixedly connected to the bottom of each of the lowest stirring rods 44, and the scraper 46 is fixedly connected to the end of each group of stirring rods 44. The shovel block 45 is a block with a parallelogram cross-section. Two identical shovel blocks 45 are provided at the bottom of each of the lowest stirring rods 44. The bottom of the shovel block 45 can contact the bottom of the cavity of the stirring drum 20. The scraper 46 is a rod with a triangular cross-section. The outer wall of the scraper 46 can contact the arc surface of the cavity of the stirring drum 20.

[0033] In practical use, the scraper 46 can scrape the inner wall of the mixing drum 20 as the mixing rod 44 rotates, scraping off the cow manure compost attached to the inner wall of the mixing drum 20, and the shovel 45 can shovel up the cow manure compost at the bottom of the mixing drum 20 as the mixing rod 44 rotates.

[0034] In summary, by setting up auxiliary structures, it is possible to prevent cow manure compost from accumulating and forming clumps on the inner wall of the mixing drum 20, thus facilitating the subsequent cleaning of the device.

[0035] Working principle: First, the cow manure compost to be mixed is poured into the cavity of the mixing drum 20 through the opening at the top of the mixing drum 20. Then, the power is turned on. When the power is turned on, the mixing motor 21 and the servo motor 33 will be energized synchronously. The mixing motor 21 drives the electric cylinder 40 to rotate, and the electric cylinder 40 is also energized. When driven by the mixing motor 21, the electric cylinder 40 rotates within the cavity of the mixing drum 20. When the electric cylinder 40 rotates, it drives the sleeve 41, the base plate 42, the support rod 43, the mixing rod 44, the shovel block 45, and the scraper 46 to rotate synchronously within the cavity of the mixing drum 20. The rotating mixing rod 44 can stir the cow manure compost within the cavity of the mixing drum 20. When the electric cylinder 40 rotates, it can also reciprocate in length. The sleeve 41, base plate 42, support rod 43, stirring rod 44, shovel block 45 and scraper 46 can change their horizontal height as the electric cylinder 40 retracts. When the servo motor 33 drives the rotating wheel 34 to rotate, the rotating wheel 34 can drive the toothed rail 35 to rotate around the limiting axis 31 by meshing with the toothed rail 35. When the toothed rail 35 rotates, it will drive the mixing drum 20 to shake synchronously. After the cow manure compost in the mixing drum 20 is mixed, the toothed rail 35 drives the mixing drum 20 to a horizontal position through the rotation of the rotating wheel 34. At this time, the cow manure compost in the mixing drum 20 will be discharged from the opening at the top of the mixing drum 20.
