[0032] Embodiment 1

[0033] This embodiment provides a cattle - sorting channel device capable of preventing backward movement and safely locking, as Figures 1 - 3 shown, including an arc - shaped channel plate 200. A plurality of spaced - apart connecting plates 220 are arranged on the outer arc surface of the arc - shaped channel plate 200. One end of the connecting plate 220 is fixed to the outer arc surface of the channel plate 200, and the other end is fixed to the outer support arc plate 230. The outer support arc plate 230 supports the channel plate 200. It also includes a vertical shaft 300 fixed on the bottom foundation. The axis of the vertical shaft 300 passes through the center of the channel plate 200. The vertical shaft 300 is rotationally connected to the middle position of the channel door 310. The channel door 310 can rotate. When cattle enter the inner side of the channel plate, the channel door rotates forward, thus realizing the sorting of cattle.

[0034] In this embodiment, a locking mechanism 100 is provided at the outer end of the channel plate portion on one side of the vertical axis for cooperation with the staff. Correspondingly, a plurality of locking holes 210 are arranged at intervals on the channel plate 200. The locking mechanism 100 cooperates with the locking holes 210, so that the channel door can only rotate forward, and when the channel door 310 cannot rotate backward due to the cooperation between the locking mechanism and the locking holes.

[0035] In this embodiment, the channel door portion on one side of the vertical axis for cooperation with the staff adopts a solid plate structure, and the channel door portion on the other side adopts a mesh structure.

[0036] Along the forward rotation direction of the channel door, the locking mechanism is installed on the surface of the downstream side of the outer end of the channel door.

[0037] Correspondingly, an operation opening 320 is provided on the channel door, which facilitates the staff to pass their hands through the channel door 310 to operate the locking mechanism 100, thereby releasing the locked state of the locking mechanism 100.

[0038] As Figures 4 - 5 shown, the locking mechanism 100 includes a frame body 110. The frame body 110 includes a bottom plate 110, a hinge seat, a handle bracket 114, a spring ear 115, a limiting member, etc.

[0039] The bottom plate 110 is fixed on the surface of the channel door 310.

[0040] An articulated seat is provided at the outer end of the bottom plate 110, that is, the end close to the channel plate. The articulated seat is rotatably connected to a non-end position of the locking tongue 131. The outer end of the locking tongue 131 is used to cooperate with the locking hole 210. The bottom plate 110 is also rotatably connected to a non-end position of the handle 121. A long strip chute is provided at the outer end of the handle 121. A connecting member is vertically connected to the inner end of the locking tongue 131. The connecting member passes through the handle 121 through the long strip chute. When the handle 121 rotates, the connecting member slides in the long strip chute, and the locking tongue 131 can be driven to rotate through the connecting member.

[0041] Specifically, the hinge seat includes two side plates 112. The two side plates 112 are arranged in parallel. One end of the two side plates 112 is fixedly connected to the bottom plate 110. Through holes are provided on the two side plates 112. A locking tongue pin shaft 132 is provided between the two side plates. Both ends of the locking tongue pin shaft 132 extend out of the side plates 112 through the through holes and are rotatably connected to the side plates 112. The locking tongue pin shaft 132 is fixed to a non-end position of the locking tongue 131. The locking tongue 131 passes through the space between the two side plates 112. The locking tongue 131 is rotatably connected to the side plates 112 through the locking tongue pin shaft 132.

[0042] Further, in order to prevent the locking tongue 131 from shaking, an opening pin 133 is connected to the part of the locking tongue pin shaft 132 extending outside the side plate 112, and the opening pin 133 contacts the outer side surface of the side plate 112.

[0043] In this embodiment, along the direction from inside to outside, that is, along the direction towards the channel plate 200, the locking tongue 131 includes a first locking tongue part 131-1, a second locking tongue part 131-2, and a third locking tongue part 131-3 which are integrally connected. Along the forward rotation direction of the channel door 310, the upstream end surfaces of the first locking tongue part 131-1, the second locking tongue part 131-2, and the third locking tongue part 131-3 are flush. One end of the first locking tongue part 131-1 is connected to a connecting member, and the other end is integrally connected to one end of the second locking tongue part 131-2. The second locking tongue part 131-2 is connected with a locking tongue pin shaft 132. The other end of the second locking tongue 131-2 is integrally connected to one end of the third locking tongue part 131-3, and the third locking tongue part 131-3 can be inserted into the lock hole 210.

[0044] Along the forward rotation direction of the channel door 310, the downstream end surface of the second locking tongue part 131-2 is a positioning surface 131-4. One end of the two side plates 112 is fixed to the bottom plate 111, and a limiting member is arranged between the other ends. Preferably, the limiting member is a limiting plate 113. The positioning surface 131-4 of the second locking tongue part 131-2 can contact the limiting plate 113, so as to limit the rotation direction of the locking tongue 131 to one side. Since both the positioning surface 131-4 and the limiting plate 113 are located on the downstream side, when the channel door 310 rotates in the reverse direction, the positioning surface 131-4 can contact the limiting plate 113 to prevent the locking tongue 131 from further rotating, so that the locking tongue 131 always maintains the matching state with the lock hole 210, thereby realizing the locking of the reverse rotation of the channel door 310.

[0045] Further, along the direction from inside to outside, the positioning surface 131-4 includes a quarter circular arc surface and a plane. The plane is used to contact and fit with the limiting plate 113, and the position of the circular arc surface corresponds to the position of the locking tongue pin shaft 132 so that the third locking tongue part 131-3 of the locking tongue 131 can rotate along the direction away from the limiting plate 113.

[0046] Further, along the direction from inside to outside, the thickness of the third locking tongue part 131-3 gradually decreases. Since the upstream end surface of the third locking tongue part 131-3 is flush with the first locking tongue part 131-1 and the second locking tongue part 131-2, the surface of the downstream side of the third locking tongue part 131-3 for contacting the lock hole 210 is an inclined surface. When the channel door 310 rotates forward, it is convenient for the third locking tongue part 131-3 to slide out of the lock hole.

[0047] The outer end of the first locking tongue portion 131-1 is integrally connected to the second locking tongue portion 131-2, and a connecting member is vertically provided at its inner end, and the connecting member is arranged parallel to the bottom plate.

[0048] In this embodiment, the connecting member is a connecting bolt 134. After the rod portion of the connecting bolt 134 passes through the first locking tongue portion 131-1, it passes through the handle 121 through a long strip chute. A limiting component is arranged on the portion of the rod portion of the connecting bolt 134 extending outside the handle 121 to cooperate with the head of the connecting bolt 134 to prevent the connecting bolt 134 from detaching from the handle 121 and the first locking tongue portion 131-1.

[0049] Preferably, the limiting component includes a nut 135 and a gasket 136. The nut 135 is threadedly connected to the rod portion of the connecting bolt 134, and the gasket 136 is sleeved on the outer periphery of the rod portion and arranged between the nut 135 and the outer side surface of the handle 121.

[0050] An elastic member is provided between the inner end of the first locking tongue portion 131-1 and the bottom plate. Preferably, the elastic member is a spring 141. One end of the spring 141 is sleeved on the outer periphery of the rod portion of the connecting bolt 134, and the sleeved position is between the inner end of the locking tongue 131 and the head of the connecting bolt 134, so as to realize the connection with the inner end of the first locking tongue portion. The other end is connected to a spring hanger 115 provided on the bottom plate through a connecting component.

[0051] Furthermore, the connecting component is a hanger bolt 142. The hanger bolt 142 is threadedly connected to the spring hanger 115 through a threaded through hole provided on the spring hanger 115. The head of the hanger bolt 142 is attached to the outer side surface of the spring hanger 115. The rod portion of the hanger bolt 142 passes through the spring hanger 115 and is then threadedly connected to a hanger nut 143. The end of the spring 141 is sleeved on the outer periphery of the rod portion of the hanger bolt 142 and is located between the hanger nut 143 and the inner side surface of the spring hanger 115.

[0052] In this embodiment, the handle 121 adopts a V-shaped structure, including two handle portions distributed at a set obtuse angle. Two handle brackets 114 are provided on the bottom plate. The corner position of the handle 121 passes through the space between the two handle brackets 114 and is rotatably connected to the handle brackets 114.

[0053] Specifically, a handle pin shaft 122 is provided at the corner position of the handle 121. The handle pin shaft 122 passes through the handle bracket 114 through a through hole provided on the handle bracket 114 and is rotatably connected to the handle bracket 114. An opening pin 123 is provided on the portion of the handle pin shaft 122 extending outside the handle bracket 114, and the opening pin 123 is attached to the outer side surface of the handle bracket 114 to prevent the handle 121 from shaking.

[0054] When the cattle sorting channel device of this embodiment works, such asFigures 6 - 9 As shown, the passage door 310 rotates in the forward direction, and the outer end of the third locking tongue portion 131-3 of the locking tongue 131 slides along the inner side surface of the passage plate 200. Under the action of the spring 141, the end of the third locking tongue portion 131-3 is always in contact with the inner side surface of the passage plate 200. When the third locking tongue portion 131-3 moves to the position of the locking hole 210, under the action of the spring 141, the third locking tongue portion 131-3 automatically extends into the locking hole 210. The passage door 310 continues to rotate, and the locking tongue 131 slides out of the locking hole 210 against the elastic force of the spring 141, and continues to move with the passage door 310 and extends into the next locking hole 210.

[0055] If a cattle touches the passage door 310 in reverse, after the third locking tongue portion 131-3 of the locking tongue 131 extends into the locking hole 210, the positioning surface 131-4 contacts the limiting plate 113, and the locking tongue 131 cannot rotate, forming a self-locking to prevent further reverse rotation of the passage door 310. Therefore, the passage door 310 can only rotate in the forward direction, as Figure 10 As shown, after all cattle have completely passed through the cattle sorting passage device, the staff passes their hand through the operation opening 320 on the passage door 310 and then rotates the handle 121, so that the third locking tongue portion 131-3 leaves the locking hole 210, and the passage door 310 rotates in the reverse direction to the initial position, and the cattle sorting operation for the next batch of cattle can be carried out.

[0056] In the cattle sorting passage device of this embodiment, through the setting of the locking mechanism and the locking hole 310, the reverse rotation of the passage door 310 is avoided, thereby avoiding harm to cattle and staff.

[0057] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. 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.
