DETAILED DESCRIPTION

[0024] Example 1

[0025] As Figures 1 to 3As shown, a dairy cow grouping device comprises a main passage 5 and two branch passages 24 arranged at the exit of the right end of the main passage 5. The ground of the main passage 5 and the two branch passages 24 is poured with concrete, and of course, the snowflake non-slip board can be paved, and the side wall is a guardrail 22 welded by square tube with width of 20 mm or round tube with diameter of 20 mm. The two branch passages 24 are respectively a second branch passage 19 consistent with the direction of the main passage 5 and a first branch passage 16 with an angle between the main passage 5. The main passage 5, the first branch passage 16 and the second branch passage 19 are connected to form a Y-shaped. The door leaf 14 is rotatably connected between the first branch passage 16 and the second branch passage 19, the frame of the door leaf 14 is welded by square tube with width of 20 mm, and the square tube is paved with steel wire mesh. The door leaf 14 blocks the entrance of the first branch passage 16, so that the second branch passage 19 is communicated with the main passage 5. The connecting part of the first branch passage 16 and the second branch passage 19 is rotatably connected with the rotating shaft of the door leaf 14.

[0026] Two grouping pedals 7 are arranged at the bottom of the main passage 5 along the length direction, the inner sides of the two grouping pedals 7 are hingedly connected to form a herringbone shape, the left side of the left grouping pedal 7 is rotatably connected with the main passage 5, and the right end of the right grouping pedal 7 is hingedly connected with three sliders 10 with T-shaped cross section. The sliders 10 are horizontally slidably connected with the main passage 5, and the grouping pedals 7 are drivingly connected with the door leaf 14. Three slide seats 12 consistent with the direction of the main passage 5 are fixedly arranged at the bottom of the main passage 5, and the three sliders 10 correspond to the three slide seats 12 one by one. The lower part of each slider 10 is located in the T-shaped groove of the corresponding slide seat 12, so as to realize the sliding connection between the slider 10 and the slide seat 12. The spring 11 is arranged between the right end of each slider 10 and the slide seat 12. The flexible rubber plate 20 is arranged on the slide seat 12, and the rubber plate 20 is fixedly connected with the corresponding grouping pedal 7. When the slider 10 slides along the slide seat 12, the rubber plate 20 slides along the surface of the slide seat 12, so as to prevent dirt from entering the T-shaped groove of the slide seat 12.

[0027] The rotating shaft of the left side of the left grouping pedal 7 extends outwardly from the guardrail 22, and a first swing arm 6 fixedly connected with the rotating shaft is arranged at the end of the rotating shaft. The lower part of the rotating shaft of the door leaf 14 is sleeved with a torsion spring 23, and the two ends of the torsion spring 23 are clamped on the door leaf 14 and the main passage 5 respectively. The torsion force of the torsion spring 23 makes the door leaf 14 block the first branch passage 16 in normal state, so that the second branch passage 19 is communicated with the main passage 5.

[0028] The lower end of the rotating shaft of the door leaf 14 is rotatably connected with the bottom of the main passage 5, and a second swing arm 15 fixedly connected with the rotating shaft is arranged on the rotating shaft. The first pull cable 9 is connected between the other end of the first swing arm 6 and the other end of the second swing arm 15. The first pull cable 9 is a steel wire rope with diameter of 4 mm, and is arranged in the groove dug in the ground in advance, and the groove is covered with a cover plate.

[0029] When the group division pedal 7 is stepped on, the first swing arm 6 swings and pulls the second swing arm 15 to swing through the first pull cable 9.

[0030] The inner sides of the two group division pedals 7 are flat, and the bottoms of the inner sides of the two group division pedals 7 are hingedly connected to each other, and when the two group division pedals 7 are in a horizontal plane, the inner sides of the two group division pedals 7 are vertical and abut against each other.

[0031] The working process of the utility model is as follows:

[0032] When the cow 21 enters from the left end of the main passage 5, the cow 21 walks along the main passage 5 to the right. When the cow 21 steps on the two group division pedals 7, if the weight of the cow 21 reaches the group division weight, the group division pedal 7 is stepped to the bottom and abuts against the two support tables below, at this time, the two group division pedals 7 are in the same horizontal plane, the flat inner sides of the two group division pedals 7 abut against each other, and the force applied to the group division pedal 7 by the sliding block 10 is perpendicular to the flat plane, so as to reach the rotation dead point of the two group division pedals 7. In this process, the first swing arm 6 swings and pulls the second swing arm 15 to swing through the first pull cable 9, and further makes the door leaf 14 rotate, so that the door leaf 14 blocks the entrance of the second sub-passage 19, thereby connecting the first sub-passage 16 with the main passage 5. After the cow 21 leaves the group division pedal 7, since the two group division pedals 7 are located at the rotation dead point, and the force applied to the first swing arm 6 by the torsional spring 23 through the second swing arm 15 and the first pull cable 9 is insufficient to reach the force required for the two group division pedals 7 to get rid of the dead point, the two group division pedals 7 remain in the horizontal state, so that the position of the door leaf 14 is maintained, thereby making the cow 21 enter the first sub-passage 16. If the weight of the cow 21 does not reach the group division weight, the two group division pedals 7 cannot be stepped to the bottom, so that when the cow 21 passes through the group division pedal 7, the door leaf 14 will be back to the original position after swinging under the action of the torsional spring 23, so that the cow 21 enters the second sub-passage 19.

[0033] The utility model can replace manual work to realize the group division of the cow 21, can improve the efficiency and accuracy of the group division, is not influenced by the experience of the feeder, and improves the group division efficiency. In addition, since the utility model does not adopt any electronic element, but adopts a pure mechanical structure to realize the group division of the cow 21, the utility model is moisture-proof, corrosion-resistant, has low failure rate, and does not need an additional power supply, and is especially suitable for occasions lacking power supply.

[0034] Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is as follows:

[0036] The first sub-passage 16 is provided with a reset pedal 17, the left end of which is hinged to the sub-passage 24, and the right end of which is connected with a second pull cable 13 for pulling the two sub-pedals 7 upward, the second pull cable 13 being a steel wire rope with a diameter of 4 mm. One end of the second pull cable 13 is tied to the right side of the reset pedal 17, and the other end goes upward, then along the guard rail 22 to the upper side of the joint of the two sub-pedals 7, and then is tied downward to the joint of the two sub-pedals 7. The guard rail 22 is provided with guide pipes along the second pull cable 13, and the second pull cable 13 passes through the guide pipes. The guide pipes are used to ensure the smooth movement and turning of the second pull cable 13.

[0037] When the two sub-pedals 7 are stepped on, the right end of the reset pedal 17 is raised, and when the cow 21 reaching the sub-group gravity enters the first sub-passage 16, it walks along the first sub-passage 16. After stepping on the reset pedal 17, the joint of the two sub-pedals 7 is pulled upward by the second pull cable 13, so that the two sub-pedals 7 are separated from the dead point position, and under the action of the torsional spring, the door leaf 14 returns to the initial position.

[0038] Example 3

[0039] In combination Figures 4 to 6 As shown in the drawings, the difference between this embodiment and example 2 is that:

[0040] The main passage 5 is provided with a vertical herringbone isolation fence 4 on the side away from the sub-passage 24 of the sub-pedal 7, the isolation fence 4 being welded by steel pipes with a diameter of 20 mm. The left part of the isolation fence 4 is a swing part 2, and the right part is a pushing part 3. The joint of the swing part 2 and the pushing part 3 is rotationally connected to one side of the main passage 5, the outer end of the pushing part 3 extends into the main passage 5 and is close to the other side of the main passage 5, and the swing part 2 is flush with the inner side of the main passage 5, which corresponds to the rotation part of the swing part 2.

[0041] The swing part 2 is fixedly connected with an arc-shaped blocking part 1 at the end away from the pushing part 3, and the end away from the swing part 2 of the blocking part 1 is bent outward.

[0042] When the cow 21 enters from the left end of the main passage 5, walks to the right and pushes the pushing part 3 with the head, the pushing part 3 is counterclockwise rotated, and at the same time, the blocking part 1 is blocked at the tail of the cow 21, so as to prevent the next cow 21 from following the cow 21, so as to keep the distance between the cows 21 and prevent two cows 21 from stepping on the sub-pedal 7 at the same time, so as to exceed the sub-group weight and cause errors in sub-grouping.

[0043] When the cow 21 walks to the right and separates from the pushing part 3, the next cow 21 pushes the blocking part with the head, so that the blocking part 1 and the pushing part are clockwise rotated and reset. Of course, the reset of the isolation fence 4 can also be realized by providing a spring at the rotation part of the isolation fence 4.
