DETAILED DESCRIPTION

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0035] Embodiment 1: A collecting and cleaning machine for pre-treatment of cow dung, such as Figure 1-Figure 15 As shown, it includes a vehicle body 1, wheels 101, a rotating shaft 1011, a fixed shovel plate 102, a top cover plate 103, a conveyor belt 2, a rotary cutting mechanism and a downward pressing slitting mechanism. A rotating shaft 1011 is rotatably provided at the rear side of the vehicle body 1, and wheels 101 are fixedly connected to both sides of the rotating shaft 1011. The front side of the vehicle body 1 is also rotatably connected to wheels 101. The wheels 101 at the front and rear sides of the vehicle body 1 are different in size. The vehicle body 1 as a whole remains parallel to the ground. A fixed shovel plate 102 is fixedly connected to the front side of the vehicle body 1. During the movement of the vehicle body 1, the fixed shovel plate 102 can shovel up the dried cow dung on the ground. A conveyor belt 2 is installed in the vehicle body 1. The cow dung shoveled by the fixed shovel plate 102 will be conveyed to the inside of the vehicle body 1 by the conveyor belt 2. A top cover plate 103 is fixedly connected to the vehicle body 1. A rotary cutting mechanism is installed in the vehicle body 1. The rotary cutting mechanism will cut and crush the cow dung sent into the vehicle body 1. A downward pressing and cutting mechanism is installed in the vehicle body 1. The downward pressing and cutting mechanism will pre-crush the cow dung on the conveyor belt 2.

[0036] A power motor is installed on the outside of the vehicle body 1. When collecting cow dung, the vehicle body 1 is driven to move by an external power mechanism. When the fixed shovel plate 102 on the vehicle body 1 contacts the cow dung, as the vehicle body 1 continues to move, the fixed shovel plate 102 scoops up the cow dung. During the movement of the vehicle body 1, the power motor installed outside the vehicle body 1 drives the rotary cutting mechanism to operate, and the rotary cutting mechanism drives the conveyor belt 2 to rotate when it operates. After the cow dung moves along the fixed shovel plate 102 to the conveyor belt 2, the conveyor belt 2 transports the cow dung into the vehicle body 1. The cow dung transported into the vehicle body 1 is cut and crushed by the rotary cutting mechanism. During the process of conveying the cow dung by the conveyor belt 2, the rotary cutting mechanism drives the downward pressing and cutting mechanism to operate, and the downward pressing and cutting mechanism performs preliminary extrusion and crushing processing on the cow dung on the conveyor belt 2.

[0037] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 3 As shown, the rotary cutting mechanism includes a rotary wheel 3, a rotary cutting frame 301, a fixed guide rod 303, a straight cutter 304 and a mobile crushing assembly. The rotary wheel 3 is installed outside the vehicle body 1, and the rotary cutting frame 301 is rotatably connected inside the vehicle body 1. The rotary wheel 3 is fixedly connected to the rotary cutting frame 301. The external power drives the rotary cutting frame 301 to rotate through the rotary wheel 3. The fixed guide rod 303 is fixedly connected inside the rotary cutting frame 301. The straight cutters 304 are fixedly connected to the outside of the rotary cutting frame 301 at uniform intervals. When the rotary cutting frame 301 rotates, the straight cutters 304 cut the cow dung into pieces, so that the cow dung falls into the rotary cutting frame 301. The mobile crushing assembly is installed in the rotary cutting frame 301, and the mobile crushing assembly crushes the cow dung entering the rotary cutting frame 301.

[0038] like Figure 3As shown, the mobile crushing assembly includes a reciprocating screw rod 302, a fixed partition plate 305, a mobile disk 306, a mobile cutter 307 and a fixed disk 308. The fixed disk 308 is fixedly connected to the vehicle body 1, and the reciprocating screw rod 302 is fixedly connected to the middle part of the fixed disk 308. The reciprocating screw rod 302 passes through the rotating cutting frame 301 and is located inside it. The fixed partition plate 305 is fixedly connected to the middle part of the fixed guide rod 303 in the rotating cutting frame 301, and the mobile disk 306 is slidably connected to the fixed guide rod 303. Both sides of the mobile disk 306 are fixedly connected with mobile cutters 307. When the rotating cutting frame 301 rotates, the mobile disk 306 will slide along the reciprocating screw rod 302, and the mobile cutter 307 on the mobile disk 306 will crush the cow dung in the rotating cutting frame 301.

[0039] When the dry cow dung is conveyed to the rotary cutting frame 301 inside the vehicle body 1 by the conveyor belt 2, as the conveyor belt 2 continues to rotate, the dry cow dung will remain between the conveyor belt 2 and the rotary cutting frame 301. As the rotary cutting frame 301 rotates continuously, the straight cutting knife 304 outside the rotary cutting frame 301 will continuously cut the dry cow dung, and the dry cow dung cut by the straight cutting knife 304 will fall into the rotary cutting frame 301. The cow dung blocks falling into the rotary cutting frame 301 are restricted by the fixed guide rod 303 and the straight cutting knife 304, and it is difficult to fall out of the rotary cutting frame 301. Since the fixed disk 308 and the reciprocating screw rod 302 are fixed to the vehicle body 1, the reciprocating screw rod 302 will not rotate. During the continuous rotation of the rotary cutting frame 301, the movable disk 306 will move along the fixed guide rod 303 under the action of the reciprocating screw rod 302. The movable cutter 307 on the movable disk 306 moves with the reciprocating sliding. When the two movable disks 306 move toward the fixed partition 305, the movable disk 306 pushes the cow dung in the rotary cutting frame 301 and cooperates with the fixed partition 305. The movable cutter 307 first cuts the cow dung into pieces, and then the movable disk 306 and the fixed partition 305 squeeze and crush the cow dung. When the movable disk 306 moves in a direction away from the fixed partition 305, the movable disk 306 pushes the cow dung in the rotary cutting frame 301 toward its side wall, and then the movable disk 306 cooperates with the rotary cutting frame 301 to squeeze and crush the cow dung. The crushed cow dung leaks downward from the gap between the straight cutters 304 on the rotary cutting frame 301, thereby realizing the function of squeezing and crushing the cow dung in the rotary cutting frame 301.

[0040] like Figure 2 , Figure 4 and Figure 5As shown, the downward pressing and slitting mechanism includes a support plate 2001, a conveying gear 201, a movable rack 202, a pull rod 203, a sliding pressure plate 204 and a crushing block 2041. The support plate 2001 is fixedly connected to the vehicle body 1, and the support plate 2001 is located in the conveyor belt 2. The conveying gear 201 is rotatably connected to the outside of the vehicle body 1. The conveying gear 201 is connected to the upper roller of the conveyor belt 2 through a one-way bearing. The movable rack 202 is slidably connected to the outside of the vehicle body 1. The movable rack 202 02 is meshed with the conveying gear 201, and a pull rod 203 is rotatably connected to the outer edge of the rotating wheel 3, and the other end of the pull rod 203 is rotatably connected to the moving rack 202. When the rotating wheel 3 rotates, the moving rack 202 is driven by the pull rod 203 to slide back and forth along the vehicle body 1. A sliding pressure plate 204 is slidably connected inside the vehicle body 1, and a crushing block 2041 is evenly fixed to the sliding pressure plate 204 on the side facing the conveyor belt 2, and the sliding pressure plate 204 is fixed to the moving rack 202.

[0041] When the rotating wheel 3 rotates, the moving rack 202 is pulled by the pull rod 203 to slide back and forth on the vehicle body 1. When the moving rack 202 descends, the moving rack 202 will not drive the conveyor belt 2 to rotate through the conveying gear 201. When the moving rack 202 rises, the moving rack 202 can drive the conveyor belt 2 to rotate a certain angle through the conveying gear 201. When the moving rack 202 descends, the moving rack 202 drives the sliding pressure plate 204 to descend along the vehicle body 1 and cooperates with the crushing block 2041 to squeeze and crush the cow dung on the conveyor belt 2. In this process, the support plate 2001 provides support for the conveyor belt 2 to prevent the conveyor belt 2 from being damaged by pressure deformation during the descent of the sliding pressure plate 204. When the moving rack 202 rises, the sliding pressure plate 204 and the crushing block 2041 rise and reset accordingly.

[0042] Embodiment 3: Based on embodiment 2, Figure 6 and Figure 7 As shown, it also includes a rotating wheel 205, a sliding rack 206, a return spring 207, a throwing gear 208 and a rotating throwing plate 209. The lower roller end of the conveyor belt 2 is fixedly connected to the rotating wheel 205, and a protrusion is provided on the rotating wheel 205. A sliding rack 206 is slidably connected in the vehicle body 1, and the end of the sliding rack 206 close to the rotating wheel 205 is an upward arc. A return spring 207 is provided between the sliding rack 206 and the vehicle body 1, and one end of the return spring 207 is fixed to the sliding rack 206, and the other end of the return spring 207 is fixed in the vehicle body 1. A rotating throwing plate 209 is rotatably connected in the fixed shovel plate 102, and the end of the rotating shaft of the rotating throwing plate 209 is fixedly connected to the throwing gear 208, and the throwing gear 208 is meshed with the sliding rack 206.

[0043] When the moving rack 202 drives the conveyor belt 2 to rotate through the conveying gear 201, the roller at the bottom of the conveyor belt 2 drives the rotating wheel 205 to rotate. Every time the moving rack 202 moves up and down, the rotating wheel 205 rotates 360 degrees. When the rotating wheel 205 rotates, the convex block on its outside pushes the sliding rack 206 to slide along the vehicle body 1 and compresses the return spring 207. During the sliding process, the sliding rack 206 drives the rotating throwing plate 209 to swing upward through the throwing gear 208. The rotating throwing plate 209 swings upward to throw the cow dung on the fixed shovel plate 102 toward the conveyor belt 2, so as to cooperate with the conveyor belt 2 to quickly transport the cow dung into the vehicle body 1. After the convex block is out of contact with the sliding rack 206, under the push of the return spring 207, the sliding rack 206 slides and resets along the vehicle body 1, and the throwing gear 208 and the rotating throwing plate 209 rotate and reset accordingly.

[0044] like Figure 8 and Fig. 9 As shown, it also includes a fixed frame 4, a sliding link 401, a support spring 402, a fixed guide frame 403 and a lifting screen frame 404. The fixed frame 4 is fixedly connected to the vehicle body 1, the fixed guide frame 403 is fixedly connected to the fixed frame 4, the lifting screen frame 404 is slidably connected to the fixed frame 4, the lifting screen frame 404 is slidably connected to the fixed guide frame 403, the lifting screen frame 404 is fixedly connected to the outside of the sliding link 401, the sliding link 401 passes through the vehicle body 1 and is slidably connected thereto, a support spring 402 is provided between the sliding link 401 and the vehicle body 1, one end of the support spring 402 is fixedly connected to the sliding link 401, and the other end is fixedly connected to the vehicle body 1.

[0045] The crushed cow dung in the rotating cutting frame 301 will fall downward into the lifting screen frame 404. When the rotating wheel 3 rotates, the convex block on its outside pushes the sliding link 401 to slide downward along the vehicle body 1 and compresses the supporting spring 402. When the sliding link 401 descends, it drives the lifting screen frame 404 to slide downward along the fixed guide frame 403 and the fixed frame 4. When the convex block on the outside of the rotating wheel 3 is out of contact with the sliding link 401, the supporting spring 402 will push the sliding link 401 to slide upward and reset, and at the same time drive the lifting screen frame 404 to slide upward and reset. As the rotating wheel 3 continues to rotate, the sliding link 401 and the lifting screen frame 404 continue to move up and down, and the lifting screen frame 404 moves up and down to screen the cow dung inside.

[0046] like Figure 10-12As shown, it also includes a first belt transmission member 1012, a second belt transmission member 1013, a feeding frame 5, a receiving frame 501, a spiral feeding shaft 502, a discharge port 503, a rotating screw 6, a material dividing frame 601, a movable push plate 602, a spur rack 603, a transmission gear 604, a rotating cutting shaft 605, a material transfer frame 606 and a rear car frame 7.
