Description

Technical Field

[0001] This utility model relates to the field of cow manure treatment technology, specifically an automatic dry and wet separation device for cow manure. Background Technology

[0002] Cow dung is the excrement of cows. With the rapid development of the cattle industry, manure pollution has become a major problem. Cow dung has many uses. It can be processed into organic fertilizer to obtain higher economic benefits. Cow dung contains a large amount of organic fertilizer, which can be recycled or dried and used as fuel. The nutrients contained in organic fertilizer are mostly in organic state, which is difficult for crops to use directly. It needs to be processed by microorganisms to slowly release various nutrients and supply nutrients to crops. Therefore, it is necessary to separate the manure into dry and wet parts to reduce the weight of the manure and facilitate subsequent composting. For this purpose, a dry and wet separation device is needed.

[0003] A search revealed Chinese patent CN218778834U, which discloses a fecal dry-wet separation device. The device includes a base, a livestock enclosure fixedly installed on the top surface of the base, baffles slidably inserted between the middle of the left and right sides of the inner wall of the enclosure, a pushing mechanism on the surface of the enclosure, a push plate fixedly installed on the surface of the pushing mechanism, a separation component at the front of the top of the base, a U-shaped frame fixedly installed on the top surface of the base, a lifting mechanism on the surface of the U-shaped frame, and a squeezing component fixedly connected to the surface of the lifting mechanism. This invention uses the pushing mechanism to move the push plate forward, thereby concentrating and pushing the feces scattered on the top surface of the base into the separation component, eliminating the need for manual collection of animal feces and increasing efficiency. The lifting mechanism moves the squeezing component downward, squeezing the feces within the separation component to achieve deep dry-wet separation of animal feces.

[0004] Based on the above patents, the existing technology has the following shortcomings: The above patents separate cow manure into dry and wet parts by squeezing. Since there is no buffer for the inner tank, the inner tank is easily damaged due to excessive pressure. Moreover, after the cow manure is separated into dry and wet parts, the staff still need to grab the handle to remove the inner tank, pour out the cow manure, and then put the inner tank back in its original position. The operation process is not convenient and increases the labor burden of the staff. Therefore, we propose an automatic dry and wet separation device for cow manure. Utility Model Content

[0054] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0055] This utility model provides an improved automatic dry and wet separation device for cow dung. The technical solution of this utility model is as follows:

[0056] like Figures 1-6 As shown, an automatic dry-wet separation device for cow dung includes:

[0057] Machine 1, the top of machine 1 has a groove, the top of machine 1 has two circular slots, and the front of machine 1 is connected to a drain valve 9.

[0058] U-shaped frame 2, U-shaped frame 2 is connected to the top of machine base 1;

[0059] The extrusion mechanism 3 is located at the top of the U-shaped frame 2 and extends to the bottom of the inner wall of the U-shaped frame 2. The extrusion mechanism 3 is used to extrude cow dung.

[0060] Two first buffer mechanisms 4 are respectively set at the bottom of the inner wall of the two circular grooves, and both first buffer mechanisms 4 extend to the top of the machine base 1 and are connected to the extrusion mechanism 3.

[0061] Separating net 5 is connected between two first buffer mechanisms 4, which are used to initially buffer the separating net 5.

[0062] Two second buffer mechanisms 6 are provided at the bottom of the inner wall of the groove, and both second buffer mechanisms 6 are attached to the bottom of the separation net 5. The two second buffer mechanisms 6 are used to buffer the separation net 5 again.

[0063] Drive mechanism 7 is located on top of U-shaped frame 2;

[0064] Connecting component 8 is located on the back of the separating net 5. The driving mechanism 7 is used to pull the connecting component 8 to cause the separating net 5 to flip.

[0065] Cow manure is poured into the interior of the separating net 5 via an external conveying mechanism. The squeezing mechanism 3 is activated, which drives the two first buffer mechanisms 4 to compress the manure, causing the separating net 5 to descend into the groove. The two first buffer mechanisms 4 provide initial cushioning for the separating net 5. After the separating net 5 descends into the groove, it squeezes the two second buffer mechanisms 6 to compress the manure again, thus further cushioning the pressure. After the manure is squeezed, the squeezing mechanism 3 will drive the two first buffer mechanisms 4 to rise, and the two second buffer mechanisms 6 will reset, allowing the separating net 5 to move out of the groove. The driving mechanism 7 is then connected to the connecting component 8. Activating the driving mechanism 7 will drive the connecting component 8 to rise, causing the connecting component 8 to rotate the separating net 5 between the two first buffer mechanisms 4, thus allowing the manure to be poured out from the interior of the separating net 5.

[0066] Furthermore, the extrusion mechanism 3 includes:

[0067] Cylinder 301 is connected to the top of U-shaped frame 2, and the output end of cylinder 301 extends to the bottom of the inner wall of U-shaped frame 2;

[0068] Connecting plate 302, which is connected to the output end of cylinder 301;

[0069] The extrusion block 303 is connected to the bottom of the connecting plate 302.

[0070] The cylinder 301 is activated, which drives the extrusion block 303 to descend into the separation net 5 via the connecting plate 302, thereby extruding the cow manure and completing the dry-wet separation of the cow manure.

[0071] Furthermore, the first buffer mechanism 4 includes:

[0072] Sleeve 401 is connected to the bottom of connecting plate 302;

[0073] The slide rod 402 is connected inside one of the circular grooves, and the top end of the slide rod 402 extends to the inner surface of the sleeve 401;

[0074] The first damping spring 403 is connected between the top of the inner wall of the sleeve 401 and the top of the slide rod 402.

[0075] The rotating shaft 404 is rotatably connected between one side of the separating net 5 and the outer surface of the sleeve 401.

[0076] The sleeve 401 slides downward on the outer surface of the slide rod 402, thereby driving the separation net 5 to descend into the groove through the rotating shaft 404. At the same time, the first damping spring 403 will be compressed to initially buffer the squeezing force. When the sleeve 401 slides upward on the outer surface of the slide rod 402, the separation net 5 can be driven upward through the rotating shaft 404, so that the separation net 5 can be moved out of the groove.

[0077] Furthermore, the second buffer mechanism 6 includes:

[0078] Crossbar 601, crossbar 601 is connected to the inside of the groove;

[0079] Two sliders 602 are slidably connected to the outer surface of the crossbar 601;

[0080] The second damping spring 603 is connected between the two sliders 602;

[0081] Two connecting shafts 605, one end of which is hinged to the inside of two sliders 602; U-shaped blocks 604, which are all hinged to the other end of the two connecting shafts 605, and the U-shaped blocks 604 are attached to the bottom of the separating net 5.

[0082] When the U-shaped block 604 is pressed, it will cause the two connecting shafts 605 to rotate in a ring, and cause the two sliders 602 to slide in opposite directions on the outer surface of the crossbar 601, so that the second damping spring 603 is stretched, thereby buffering the extrusion force again. The reset of the second damping spring 603 will cause the U-shaped block 604 to rise, so that the separation net 5 can be removed from the inside of the groove.

[0083] Furthermore, the drive mechanism 7 includes:

[0084] Vertical plate 701 is connected to the top of U-shaped frame 2;

[0085] Motor 702 is connected to the top of U-shaped frame 2;

[0086] Support rod 703 is rotatably connected between one end of the output shaft of motor 702 and one side of vertical plate 701;

[0087] The cable reel 704 is connected to the outer surface of the support rod 703;

[0088] The lifting rope 705 is wound around the outer surface of the cable reel 704;

[0089] Hook 706 is attached to one end of the suspension rope 705.

[0090] Furthermore, the connecting component 8 includes:

[0091] Connecting block 801 is connected to the back of the separation net 5;

[0092] Hook hole 802 is formed inside the connecting block 801.

[0093] When the hook 706 is inserted into the hook hole 802, the motor 702 is started, which drives the winding drum 704 to rotate through the support rod 703, causing the hanging rope 705 to begin winding. The hook 706 then drives the vertical plate 701 to rise, causing the separation net 5 to flip over, thus facilitating the dumping of the cow dung from the separation net 5.

[0094] Furthermore, it also includes:

[0095] Multiple bases 10 are connected to the bottom of the machine base 1.

[0096] The arrangement of multiple bases 10 can improve the stability of the machine tool 1, thereby improving the overall stability of the device during operation.

[0097] In summary, the working principle of this utility model is as follows: During use, the cow dung to be processed is poured into the separation net 5. When separating the cow dung into wet and dry states, the operator activates cylinder 301. The output end of cylinder 301 extends, thereby driving the pressing block 303 to descend via connecting plate 302. Simultaneously, as connecting plate 302 descends, it causes sleeve 401 to slide on the outer surface of slide rod 402, thereby compressing the first damping spring 403 and initially buffering the downward pressure. At the same time, rotating shaft 404 drives the separation net 5 to descend. When the pressing block 303… As the cow manure is compressed inside the separating net 5, the separating net 5 continues to descend. Simultaneously, the compression block 303 separates the cow manure inside the separating net 5 into wet and dry components. When the bottom of the separating net 5 comes into contact with the top of the U-shaped block 604 after descending, it compresses the U-shaped block 604, causing it to descend further. As the U-shaped block 604 descends, it drives the two connecting shafts 605 to rotate in opposite directions. This causes one end of the two connecting shafts 605 to drive the two sliders 602 to slide in opposite directions on the outer surface of the crossbar 601, thereby stretching the second damping spring 603 and further increasing the downward pressure. The first buffer prevents excessive pressure on the separating net 5, thus avoiding damage. When the separating net 5 needs to be removed from the groove, the output end of the actuating cylinder 301 retracts, driving the squeezing block 303 to rise via the connecting plate 302. At this time, the squeezing block 303 will no longer squeeze the separating net 5, and the second damping spring 603 will reset. Simultaneously, in conjunction with the rotating shaft 404, the separating net 5 is slowly lifted from the inside of the groove, facilitating the subsequent discharge of cow dung from the separating net 5. When it is necessary to quickly discharge the cow dung from the separating net 5, the worker first hooks the hook 706 onto the hook hole 8. Inside 02, motor 702 is then started. The output of motor 702 drives the winding drum 704 to rotate via support rod 703. When the winding drum 704 rotates, it drives the hoisting rope 705 to wind up, so that the hoisting rope 705 drives the connecting block 801 to rise via hook 706. The rotating shaft 404 is rotatably connected between sleeve 401 and separation net 5, so that the connecting block 801 drives the separation net 5 to flip, thereby dumping out the cow dung in the separation net 5. At this time, the dumped cow dung can be collected through an external container for easy subsequent transfer.

[0098] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
