[0042] The working process of the livestock manure conveying and extracting equipment based on animal husbandry and veterinary is as follows:

[0043] The collected livestock manure is loaded into the conveying bucket 200 and transported by the conveyor 100. During transportation, the conveying bucket 200 is limited by the limiting plates one 101, two 102 and three 103 when moving. During the movement of the conveying bucket 200, the rack group three 106 first contacts and engages with the gear two 205. During the movement of the conveying bucket 200, the gear two 205 drives the rotating shaft one 201 to rotate, and in turn drives the stirring shaft 206 to rotate. During the rotation of the rotating shaft one 201, the fixed rod 202 and the second bevel gear 208 are stationary. When the stirring shaft 206 rotates around the fixed rod 202, the first bevel gear 207 engages with the second bevel gear 208, causing the first bevel gear 207 to rotate around the fixed rod 202 while also rotating itself. The second bevel gears 208 of adjacent groups face in opposite directions, so the stirring shafts 206 of adjacent groups rotate in opposite directions. During the rotation of the stirring shaft 206, the stirring shaft 206 rotates around the fixed rod 202, which can mix the manure inside the conveying bucket 200. At the same time, the self-rotation of the stirring shaft 206 can increase the stirring range and provide more stirring force by the synchronous rotation of the stirring rollers 209. This can improve the shear force during the mixing process, improve the breaking and mixing effect of the manure, and increase the processing cost of the subsequent utilization of the manure.

[0044] When the conveying bucket 200 is conveyed to the gear one 204 and the rack group one 104 is contacted, at this time the conveying bucket 200 has been mixed and crushed for a period of time, the gear one 204 and the rack group one 104 are engaged to drive the gear one 204 to rotate, the rotation of the gear one 204 drives the rotating shaft two 203 to rotate, because the parameters of the gear one 204 and the gear two 205 are different, the rotating speed of the gear one 204 is different from that of the gear two 205, so there is relative rotation between the rotating shaft two 203 and the rotating shaft one 201, when the rotating shaft two 203 rotates, the third bevel gear 210 and the fourth bevel gear 211 are engaged to rotate, driving the threaded rod 212 to rotate, through the threaded transmission of the threaded rod 212, the piston 213 is driven to move towards the rotating shaft one 201, the internal pressure of the stirring shaft 206 is lowered, when the piston 213 passes through the valve block two 215, the valve block two 215 moves towards the inside of the stirring shaft 206, so that the inside of the stirring shaft 206 is communicated with the outside of the stirring shaft 206 through the through hole of the valve block two 215 and the side wall, the fecal material outside the stirring shaft 206 is sucked into the inside of the stirring shaft 206, and under the rotation and mixing of the stirring shaft 206, the crushed and mixed material moves to the middle part of the stirring shaft 206 and is sucked into the inside through the valve block two 215, realizing sampling, the conveying bucket 200 continues to move to the gear two 205 and the rack group four 107 are contacted, the gear two 205 and the rack group four 107 are engaged to drive, when the gear two 205 rotates to the gap toothless area and the rack group four 107 is contacted, the gear two 205 stops rotating without the driving force of the rack group four 107, the rotating shaft one 201 and the stirring shaft 206 stop rotating, at this time the special group stirring shaft 206 for sampling is upward, at the same time the stirring shaft 206 moves to the area where the sliding block 301 is located, the material taking pipe 304 moves downward under the magnetic attraction of the magnetic block 305 and the magnetic valve core 216, at the same time the sliding block 301 can move synchronously with the stirring shaft 206 under the magnetic attraction of the magnetic block 305 and the magnetic valve core 216, because there is a gap between the two groups of magnetic blocks 305, the sealing ring at the bottom of the material taking pipe 304 automatically rotates, the corresponding magnetic block 305 and the magnetic valve core 216 automatically magnetically cooperate, and the magnetic force of the magnetic block 305 is greater than that of the magnetic valve core 216, so that after the magnetic block 305 and the magnetic valve core 216 are attracted, the magnetic valve core 216 can be attracted to the two sides, so that a gap is formed between the magnetic valve core 216, facilitating the discharge of the sample in the inside of the stirring shaft 206, at this time the gear one 204 moves to the distribution area of the rack group two 105, the gear one 204 and the rack group two 105 are contacted, driving the gear one 204 to rotate reversely, so that the threaded rod 212 reversely rotates, pushing the piston 213 away from the rotating shaft one 201, pushing the sample collected in the inside of the stirring shaft 206 into the material taking pipe 304 through the gap between the magnetic valve core 216, into the inside of the sampling bottle 303 through the material pipe 302, realizing automatic sampling without contact, when the conveying bucket 200 continues to move to the limit of the compression of the return spring 306, with the continuous movement of the conveying bucket 200, the magnetic block 305 and the magnetic valve core 216 are separated,The magnetic valve core 216 and the material taking pipe 304 are reset, the sample is collected in the sampling bottle 303, and through the inclined design of the material conveying pipe 302, the excess material is moved to the inside of the sampling bottle 303 or falls back to the inside of the conveying hopper 200 under the action of gravity, in the process, through the meshing cooperation of the gear one 204 and the gear two 205, the sample is taken after being broken and mixed in the manure conveying process, not only the manure is broken, mixed and automatically sampled without contact, the manual sampling is avoided, the sanitation of sampling is improved, and in the sampling process, the stirring shaft 206 keeps rotating and mixing, the sampling sample is located in the middle region of the stirring shaft 206, not only the external environment interference is reduced, but also the sampling deviation is reduced, the edge influence is reduced, the representativeness of the sample is improved, and the accuracy of the detection result is improved.

[0045] It should be noted that the elastic washer 217 designed at the top of the valve block one 214 can be in contact with the piston 213 after the threaded rod 212 continues to rotate when the piston 213 moves to the lowest position, so that the piston 213 no longer continues to move, and the elastic washer 217 provides a thrust to the piston 213 through the elastic design, and when the threaded rod 212 reverses, the piston 213 is pushed to be threadedly connected with the threaded rod 212, so that the threaded transmission is guaranteed, and the inside top of the stirring shaft 206 is designed in the same way as the elastic washer 217, so that when the piston 213 moves to the limit position at both ends in the stirring shaft 206, the piston 213 continues to be driven by the threaded rod 212 and does not appear to be stuck.

[0046] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
