[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1 - Figure 8 The mixing device for harmless treatment and manufacturing of livestock and poultry manure shown in the figure comprises a mixing box 1, an L-shaped main body bracket 2 is fixedly installed on the top of the mixing box 1, a discharge barrel 3 is fixedly arranged on the surface of the L-shaped main body bracket 2, an opening groove is arranged on the surface of the L-shaped main body bracket 2 and directly below the discharge barrel 3, a discharge hopper 4 is installed on the top of the discharge barrel 3, an impact mechanism 5 is installed on one side of the L-shaped main body bracket 2, a matching groove 20 is opened on the end face of the discharge barrel 3 close to the impact mechanism 5, the impact mechanism 5 cooperates with the matching groove 20, a blocking mechanism 6 is arranged on the other side of the L-shaped main body bracket 2, and the discharge barrel 3 closes the blocking mechanism 5. The end surface of the mechanism 6 is provided with a bottom groove 21 and a top groove 22, and the bottom groove 21 and the top groove 22 are respectively arranged at the bottom and the top of the lower barrel 3. The sealing mechanism 6 and the bottom groove 21 and the top groove 22 cooperate with each other. By setting the impact mechanism 5, the dry block livestock and poultry manure in the lower barrel 3 can be impacted and crushed. After adding it into the mixing device, by setting the sealing mechanism 6, the upper and lower ports of the lower barrel 3 can be alternately blocked to ensure that the manure will not splash out during the impact and crushing process of the manure. At the same time, the crushed manure can be intermittently added to the mixing box 1 to further ensure the mixing efficiency of the mixing box 1.

[0018] The impact mechanism 5 includes an impact block 14, which is movably installed in the lower barrel 3 through a matching groove 20. A pull rod 12 is installed at the other end of the impact block 14. The pull rod 12 penetrates the upper surface of the L-shaped main body bracket 2. A first spring 15 is provided between the impact block 14 and the upper surface of the L-shaped main body bracket 2. A first back plate 7 is installed at the end of the L-shaped main body bracket 2 through bolts. A support platform is installed on the end surface of the first back plate 7. A stepper motor 8 is installed on the surface of the support platform. A rotary actuator 15 is installed at the output end of the stepper motor 8. The end surface of the turntable 9 is fixedly provided with a convex block, and a telescopic cylinder is fixedly installed on the surface of the convex block. The telescopic cylinder is directly below the pull rod 12. A platform is provided at the bottom of the pull rod 12 away from the end of the impact block 14. A stop column 13 is fixedly installed in the middle of the platform. The stop column 13 cooperates with the telescopic cylinder. The turntable 9 is driven by the stepper motor 8 to rotate counterclockwise, and the convex block on the surface of the turntable 9 will drive the telescopic cylinder to rotate counterclockwise. When the convex block rotates above the output end of the stepper motor 8, the telescopic cylinder has a pushing effect on the stop column 13. At this time, the pull rod 12 is pulled out of the way. The rod 12 pushes toward the outside of the L-shaped main bracket 2, and at the same time, the pull rod 12 will also drive the impact block 14 to move toward the outside of the lower barrel 3. When the protrusion rotates below the output end of the stepper motor 8, the horizontal height of the telescopic cylinder is reduced. At this time, the telescopic cylinder has no effect of pushing the stop column 13. Therefore, under the elastic force of the first spring 15, the impact block 14 will quickly move to the inside of the lower barrel 3, so that the dry block of livestock and poultry manure inside the lower barrel 3 can be punched and crushed. The outer surface of the L-shaped main bracket 2 is provided with a guide Shell 16, the guide shell 16 is wrapped around the outside of the pull rod 12, and the inner wall of the guide shell 16 is provided with a groove 18, the top of the pull rod 12 is provided with a convex strip 17, the convex strip 17 is slidably installed in the groove 18, and a limit plate 19 is installed on the end face of the pull rod 12 away from the impact block 14. Under the action of the guide shell 16, the convex strip 17 and the groove 18, the moving direction of the pull rod 12 can be limited to ensure the linear motion path of the pull rod 12, ensure the accuracy of the pull rod 12 during the movement process, and ensure the stability of the device during operation.

[0019] The telescopic cylinder includes a positioning cylinder 10, which is fixedly installed on the end of the protrusion.

A protruding cylinder 11 is installed on the top of the second spring, and the top of the protruding cylinder 11 is close to the blocking column 13. When the protrusion rotates above the output end of the stepper motor 8, the protruding cylinder 11 can be retracted into the plug-in groove under the action of the second spring and the platform. When the telescopic cylinder pushes the blocking column 13, the top of the protruding cylinder 11 will always be close to the blocking column 13. When the protrusion rotates below the output end of the stepper motor 8, the horizontal height of the telescopic cylinder is reduced, and the length of the protruding cylinder 11 is less than the distance between the protrusion and the platform at this time, so that the telescopic cylinder has no effect of pushing the blocking column 13.

[0020] The end of the L-shaped main frame 2 is installed with a second back plate 23 by bolts, the first back plate 7 is parallel to the second back plate 23, and the first back plate 7 and the second back plate 23 are installed at the rear of the device, and the front end surface of the second back plate 23 is symmetrically provided with a first slide groove 24 and a second slide groove 29, the first slide groove 24 is arranged at the top of the second back plate 23, the first slide groove 24 and the top groove 22 are in the same horizontal plane, the first slide block 27 is slidably installed inside the first slide groove 24, the front end of the first slide block 27 is provided with a first movable plate 25, the first slide block 27 and the second slide groove 29 are symmetrically provided with a first slide groove 24, and the first slide block 27 and the second slide groove 29 are symmetrically provided with a first slide groove 24.

A rotating shaft is fixedly installed in the middle of the swing frame 34. By setting the swing frame 34, and the first boss 28 and the second boss 33 respectively correspond to the path grooves at both ends of the swing frame 34, when the swing frame 34 swings around the rotating shaft at its middle end, the first movable plate 25 and the second movable plate 30 will move alternately in the direction of the lower barrel 3, thereby realizing the alternating blocking of the upper and lower ports of the lower barrel 3.

[0021] The rotating shaft at the middle end of the swing frame 34 passes through the second back plate 23, and a gear 35 is installed at the other end of the rotating shaft. An L-shaped matching bracket 37 is fixedly installed at the rear of the unloading barrel 3, and a rack 36 is slidably installed inside the L-shaped matching bracket 37. The rack 36 is meshed with the gear 35, and a hook block is provided at the end of the rack 36. The hook block is fixedly connected to the impact block 14 by bolts. When the impact block 14 is displaced, the rack 36 can be driven to move through the hook block. Since the rack 36 is meshed with the gear 35, the rack 36 will drive the gear 35 to rotate, and the gear 35 will drive the rotating shaft at the middle end of the swing frame 34 to rotate, thereby realizing the swinging operation of the swing frame 34.

[0022] A support plate is provided on the top of the lower hopper 4, and a cylinder 38 is installed on the surface of the support plate.
