[0034] On the basis of the above embodiments, the technical features involved therein and the roles / functions they play, and the working process of the present application are further introduced, so that those skilled in the art can reproduce the technical solution after reading the present application.

[0035] In the present application, the base 1 is used to realize the support of the overall structure and ensure that the overall structure is always in a stable state, therefore in the present application, the base 1 should be stably connected with the horizontal plane, and itself can be a prefabricated concrete structure.

[0036] In the application, the base leg 2 is a hollow long rectangular pipe body, and a plurality of leg connecting holes 4 are arranged in the length direction of the base leg 2 and pass through the base leg 2. The base leg 2 can cooperate with the corresponding top plate leg 7, be connected with the top plate leg 7 through the leg connecting piece 3 and the leg connecting hole 4, and be aligned through different leg connecting holes 4 to adjust the relative height of the two.

[0037] In order to facilitate the position adjustment of the base leg 2 and the top plate leg 7, a leg adjustment oil cylinder 23 can also be arranged on the top surface of the base leg 2, the bottom end of the leg adjustment oil cylinder 23 is fixed to the top end of the base leg 2, and the telescopic end of the leg adjustment oil cylinder 23 is connected to the bottom surface of the top plate 8. Under the jacking action of the leg adjustment oil cylinder 23, the relative height adjustment of the top plate leg 7 and the base leg 2 can be conveniently carried out, and the relative height adjustment between the top plate 8 and the base 1 can be realized to adapt to different types and different kinds of livestock.

[0038] In the application, the top plate 8 is arranged in parallel with the base 1 and cooperates with the base 1, the top plate leg 7 and the base leg 2 to form a space for livestock protection.

[0039] The top plate 8 is also provided with a top plate sliding rail 9 at the middle position of the top surface, which extends in the length direction of the top plate 8 and can be flush with the end surface of the top plate 8. The top plate sliding rail 9 can be connected with the position adjustment plate 10 through a sliding block to satisfy the movement of the position adjustment plate 10 relative to the top plate 8. In the case where the position oil cylinder 6 is not arranged, the position fixing between the top plate 8 and the position adjustment plate 10 can be realized by fasteners, that is, by machining corresponding connecting holes on the position adjustment plate 10 and corresponding connecting holes on the top plate 8, and by aligning the connecting holes to realize the position fixing between the two. In the case where the position oil cylinder 6 is arranged, the position oil cylinder 6 can be connected with the top plate 8 through the position oil cylinder base 5, and the position oil cylinder base 5 is located at both ends of the top plate sliding rail 9. The telescopic end of the position oil cylinder 6 is connected with the position adjustment plate 10 to drive the relative movement of the position adjustment plate 10 along the top plate sliding rail 9 and the top plate 8.

[0040] In the application, the position adjustment plate 10 is symmetrically provided with a spacing adjustment oil cylinder 11 on both sides, the center axis of the spacing adjustment oil cylinder 11 is perpendicular to the center axis of the position oil cylinder 6, and the center axis of the position oil cylinder 6 is parallel to the length direction of the top plate sliding rail 9.

[0041] In the application, the telescopic end of the spacing adjustment oil cylinder 11 is connected with the spacing adjustment block 12 at the corresponding position on both sides of the position adjustment plate 10 to drive the position adjustment of the spacing adjustment block 12 relative to the top plate 8.

[0042] In the application, the top plate 8 is symmetrically processed with main sliding holes 14 and side sliding holes 15 on both sides of the top plate sliding rail 9. The main sliding hole 14 is a long strip-shaped through hole, and the side sliding hole 15 is distributed in the length direction of the main sliding hole 14 and symmetrically arranged on both sides of the main sliding hole 14.

[0043] The main sliding hole 14 and the side sliding hole 15 are also processed with a top plate sliding groove 13 composed of a stepped structure at the position of the top plate 8 corresponding to the main sliding hole 14 and the side sliding hole 15. The top plate sliding groove 13 is realized by processing a stepped structure at the edge position of the main sliding hole 14 and the side sliding hole 15, and the shape of the top plate sliding groove 13 is the same as the shape composed of the main sliding hole 14 and the side sliding hole 15.

[0044] In the application, the spacing adjustment block 12 is fixedly connected with a longitudinal sleeve 16, which extends downward after passing through the main sliding hole 14 or the side sliding hole 15 from the spacing adjustment block 12. The circumferential outer side of the longitudinal sleeve 16 is in contact with and can slide relative to the inner wall of the main sliding hole 14 or the side sliding hole 15.

[0045] The bottom surface of the spacing adjustment block 12 slides relative to the top surface of the top plate 8, and the longitudinal sleeve 16 is fixedly connected with a guide reinforcing frame 17 at the position passing through the top plate 8. The guide reinforcing frame 17 is a hollow frame body, and a sleeve limiting hole 18 composed of a strip-shaped through hole is processed at the position of the longitudinal sleeve 16 inside the guide reinforcing frame 17. The top surface of the guide reinforcing frame 17 is in contact with and slides relative to the bottom surface of the top plate 8. The guide reinforcing frame 17 can cooperate with the spacing adjustment block 12 to limit the movement of the longitudinal sleeve 16. Since the longitudinal sleeve 16 is processed with the sleeve limiting hole 18 composed of a strip-shaped through hole at this position, the guide reinforcing frame 17 also serves to ensure the strength of the longitudinal sleeve 16 at this position.

[0046] A sleeve inner rod 19 is slidably arranged inside the longitudinal sleeve 16. A plurality of inner rod threaded holes 20 are distributed in the length direction of the sleeve inner rod 19, and the inner rod threaded hole 20 can be connected with a connecting piece through a threaded structure. The connecting piece includes a connecting piece on the restraint piece and a connecting piece capable of limiting the inner rod threaded hole 20 inside the sleeve limiting hole 18.

[0047] A plurality of base limiting holes 22 are processed on the bottom surface of the top plate 8 corresponding to the main sliding hole 14 and the side sliding hole 15. Figure 1 Figure 3 The base limiting hole 22 shown in the figure is only a schematic and is the minimum number. Those skilled in the art can set different numbers of base limiting holes 22 according to actual adjustment. The sleeve inner rod 19 can be inserted into the corresponding base limiting hole 22 to realize the connection of the sleeve inner rod 19 and the base 1.​

[0048] The base limiting hole 22 is located in the base groove 21, and the two ends of the base groove 21 pass through the end surface of the base 1. The base groove 21 serves to improve the cleaning effect of the base limiting hole 22 and improve the convenience during cleaning.

[0049] In the working process of the present application, the relative height adjustment of the top plate 8 and the base 1 is realized by adjusting the oil cylinder 23 of the supporting leg. After the supporting leg connecting holes 4 on the base supporting leg 2 and the top plate supporting leg 7 are aligned, the relative fixation of the top plate supporting leg 7 and the base supporting leg 2 is realized by inserting the supporting leg connecting piece 3 into the supporting leg connecting hole 4, thereby realizing the fixation of the relative height of the top plate 8 and the base 1.

[0050] After the above fixing work is completed, the relative position of the position adjusting plate 10 is adjusted by the position oil cylinder 6 on both sides of the top plate 8, so that the longitudinal sleeve 16 and the sleeve limiting hole 18 are adjusted in the length direction of the top plate 8 and the base 1. It should be noted that at this time, the longitudinal sleeve 16 should be located in the main sliding hole 14 to meet the above-mentioned length direction adjustment.

[0051] When the above adjustment is completed, the relative position of the spacing adjusting block 12 is adjusted by the spacing adjusting oil cylinder 11, and the spacing adjusting block 12 can drive the longitudinal sleeve 16 to adjust in the direction of the side sliding hole 15. Since the side sliding hole 15 on both sides of the main sliding hole 14 is symmetrically arranged and the side sliding hole 15 and the main sliding hole 14 are through, the adjustment of the longitudinal sleeve 16 in the direction of the side sliding hole 15 can be at least arranged at the limit position of the side sliding hole 15 and the through position of the side sliding hole 15 and the main sliding hole 14. By machining the base limiting hole 22 at the corresponding position of the base 1, the sleeve inner rod 19 is inserted, and then the rod body is arranged and connected in the width direction in the space formed by the base supporting leg 2, the top plate supporting leg 7, the top plate 8 and the base 1.

[0052] In the present application, the sleeve inner rod 19 can be disconnected from the connecting piece connected to the inner rod threaded hole 20 to release the limitation of the sleeve limiting hole 18, and then can be slid downward along the longitudinal sleeve 16 into the corresponding base limiting hole 22. Threaded holes can also be machined on the longitudinal sleeve 16, for example Figure 1The sleeve inner rod 19 and the longitudinal sleeve 16 are temporarily fixed at the position shown by screwing the fastener. In this application, the position cylinder 6, the distance adjustment cylinder 11 and the leg adjustment cylinder 23 can be controlled by a proportional valve. By adjusting the opening of the proportional valve, the stroke of the hydraulic cylinder can be controlled. A servo valve can also be used to control the hydraulic stroke accurately according to the input signal. By adjusting the opening of the servo valve, the hydraulic stroke can be controlled accurately. The position cylinder 6, the distance adjustment cylinder 11 and the leg adjustment cylinder 23 work under the power provided by the hydraulic pipeline and the hydraulic system.

[0053] In this application, the inner rod threaded hole 20 on the sleeve inner rod 19 can also be connected with a binding member through a threaded structure. The binding member includes a fixing member for the head of livestock, a flexible binding member with a threaded connecting member, etc. The inner rod threaded hole 20 at different positions on the sleeve inner rod 19 can be selected flexibly according to the actual situation.

[0054] Finally, although the technical solutions are introduced and described in the form of specific embodiments in this application, the skilled in the art can combine them flexibly according to the actual situation. Such flexible combination is still within the technical scope of this application and should be regarded as an extension of the protection scope of this application.
