Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of Tan sheep breeding, more particularly, it relates to a Tan sheep breeding cage and a feeding method thereof. BACKGROUND

[0002] In the existing Tan sheep breeding technology, the feeding process relies on manual operation, and this traditional feeding method has the problem of low efficiency. The feeding personnel need to carry a large amount of feed and visit the feeding troughs distributed in each area of the sheep house one by one to add feed one by one. This manual feeding method not only consumes a large amount of human resources and time cost, but also in large-scale breeding farms, the feeding personnel need to repeatedly go back and forth between the feed storage area and each feeding point, which has a long walking distance and high labor intensity, which seriously affects the overall efficiency of the feeding work. Especially in bad weather conditions, manual feeding is more difficult, which not only increases the labor burden of the workers, but also may affect the normal diet and growth of Tan sheep due to the delay of feeding. At the same time, the traditional manual feeding method also has the problems of irregular feeding time and uneven distribution of feed, which cannot provide stable and timely nutrition supply for Tan sheep. These factors restrict the large-scale development and modernization process of Tan sheep breeding industry.

[0003] In the traditional Tan sheep feeding management, the quantitative control of feed completely depends on the experience judgment and manual calculation of the feeding personnel. This manual operation method has the defects of precision control and technical limitations. The feeding personnel need to control the amount of feed in each feeding trough according to the number, weight, growth stage and nutritional needs of Tan sheep by visual observation and experience. This subjective judgment method leads to the inaccuracy of feed distribution. Some feeding troughs may have excessive waste of feed, while others may affect the normal feeding of Tan sheep due to insufficient feed. This traditional manual quantitative method increases the cost of feed and reduces the economic benefits of breeding. SUMMARY

[0025] When feeding, the motor 13 is started, and the prepared feed is injected into the feed pipe 11. The motor 13 drives the rotation of the spiral conveying shaft 12, and the spiral blades of the spiral conveying shaft 12 continuously convey and push the injected feed during rotation, ensuring that the feed can move uniformly and stably along the feed pipe 11, avoiding the phenomenon of blockage or uneven distribution of the feed during conveying. The feed conveyed by the spiral conveying shaft passes through the several groups of discharge pipes 14 arranged on the lower surface of the feed pipe 11 and enters the inside of each quantitative wheel 21 in an orderly manner. The feed naturally falls into the receiving groove on the surface of the raking ring 24 under the action of gravity. The receiving groove on the surface of the raking ring 24 ensures that the feed can be effectively collected and temporarily stored, preparing for subsequent quantitative distribution. The falling of the feed drives the rotation of the raking ring 24, and the feed falls into the trough through the discharge port below the quantitative wheel 21. The raking ring 24 drives the rotation of the driven shaft 22, and the rotation of the driven shaft 22 drives the synchronous rotation of the drive bevel gear 27 at the end, and then the second bevel gear 210 meshing with it rotates. The second bevel gear 210 drives the rotation of the first bevel gear 29 at the other end through the connecting rod 28, and the first bevel gear 29 drives the rotation of the double-sided gear 211 meshing with it. The spur gear on the other side of the double-sided gear 211 meshes with the ring gear 25, thereby driving the ring gear 25 to make a circular motion along the surface of the quantitative wheel 21. When the ring gear 25 rotates to the preset position, the fixed clamping rod 26 on the surface of the ring gear 25 comes into contact with the clamping plate 215 on the side wall of the quantitative ring 214, and the resistance generated by this physical contact forces the ring gear 25 to stop rotating, thereby stopping the entire transmission system and the rotation of the raking ring 24, and the discharge process is terminated, realizing quantitative discharge control.

[0026] The discharge amount can be controlled by adjusting the quantitative wheel 21. When it is necessary to adjust the discharge amount, the receiving ring 33 is manually pulled. At this time, the lever 31 is not moved, and the compression spring 34 is in a compressed state. The receiving ring 33 is moved upward through the slide rod 35 to move the pushing ring 36 upward. The pushing ring 36 is moved upward to move the tension spring 39 upward, which pushes the pulling ring 38 upward. The pulling ring 38 is connected with the abutting ring 311 through the pull rod 310 to move the abutting ring 311 upward. Since the upper end of the abutting ring 311 is designed as an inclined surface, the abutting ring 311 is in contact with the circular surface at the end of the abutting rod 315 when the abutting ring 311 is moved upward, so as to push the telescopic block 313 out. At this time, the spring 312 is in a compressed state, and the insertion rod 314 is pulled out of the groove 316. The insertion rod 314 is unlocked with the fixed sleeve 32. Since the compression spring 34 is in a compressed state at this time, the compression spring 34 rebounds to move the lever 31 upward when the lock is unlocked, so as to unlock the lever 31 with the quantitative hole 213 on the surface of the positioning ring 212. The lever 31 is continuously manually pulled to rotate and adjust the quantitative ring 214. The operator determines the position corresponding to the required discharge amount by observing the scale 216 on the surface of the quantitative wheel 21. After the position is determined, the receiving ring 33 is loosened, and the upper end surface of the lever 31 is pressed by hand. When the groove 316 on the surface of the lever 31 corresponds to the insertion rod 314, the spring 312 rebounds to push the insertion rod 314 into the groove 316, so as to lock the insertion rod 314 with the lever 31, and fix the position of the quantitative ring 214. At this time, the position of the card 215 is also fixed, the relative position between the clamping rod 26 and the card 215 is changed, and the discharge amount is adjusted.

[0027] The card connection adjusting mechanism comprises a lever 31, the outer surface of the lever 31 is sleeved with a fixed sleeve 32, the outer surface of the fixed sleeve 32 is sleeved with a receiving ring 33, the upper end surface of the receiving ring 33 is provided with a compression spring 34, the other end of the compression spring 34 is fixedly connected with the inner surface of the lever 31, the lower end surface of the receiving ring 33 is connected with a plurality of slide rods 35, the other end of the slide rod 35 is provided with a pushing ring 36, a sliding groove 37 is formed in the surface of the fixed sleeve 32, the slide rod 35 is embedded in the sliding groove 37 and is in sliding connection with the sliding groove 37, the outer surface of the fixed sleeve 32 is sleeved with a pulling ring 38, the lower end surface of the pulling ring 38 is provided with a tension spring 39, the other end of the tension spring 39 is fixedly connected with the upper end surface of the pushing ring 36, the lower end surface of the pulling ring 38 is provided with a plurality of pull rods 310, the other end of the pull rod 310 is connected with an abutting ring 311, the surface of the fixed sleeve 32 is provided with a plurality of springs 312, the other end of the spring 312 is connected with a telescopic block 313, the side wall of the telescopic block 313 is provided with an insertion rod 314 at the upper and lower ends and is provided with an abutting rod 315 at the left and right ends, two grooves 316 are formed in the surface of the lever 31, and the insertion rod 314 is matched with the groove 316.
