Description

Technical Field

[0001] The invention relates to the technical field of chicken farming equipment, and more particularly to a feed adding device used in a chicken farm. Background Art

[0002] In the process of raising chickens in cages, it is necessary to add feed. However, as the scale of chicken farming expands, the original manual feeding method is inefficient and difficult to meet the needs of large-scale chicken farming, which is not conducive to the development of the overall chicken farming industry. Some chicken farms will introduce corresponding feed adding equipment.

[0003] In the prior art, when adding feed to the trough of the chicken house, a feed box is generally placed on a movable table, and the feed in the feed box is then pushed upwards through a cage, and finally added to the trough through a discharge pipe. The amount of feed in the trough can be controlled by adjusting the length of the discharge pipe. However, there are some problems in its use. In order to ensure sufficient feed, the loading speed of the cage generally exceeds the discharging speed of the discharge pipe, which may cause the feed in the discharge pipe to accumulate.

A positioning hole 81 is provided on one side of the upper end of the lifting shaft 80. A second spring ejector pin 82 is installed on one side of the fixed column 47. The telescopic end of the second spring ejector pin 82 can enter the positioning hole 81. The lifting shaft 80 is connected to the inner surface of the square groove 79 through a connecting spring 83. A moving rod 84 is installed on the telescopic end of the second spring ejector pin 82. A trapezoidal platform 85 is installed at one end of the L-shaped lifting rod 75. An intercepting rod 86 is installed on one side of the upper end of the lifting shaft 80. A pushing platform 87 is installed on one side of the upper end of the L-shaped lifting rod 75. The pushing platform 87 can push the intercepting rod 86 downward. The process of connecting the square connecting shaft 53 and the square connecting rod 54 by the connecting frame 58 is as follows: under normal conditions, the overflow box 7 is located at the top, the high-speed switch 15 is in the on state, the second square sleeve 68 fits on the outside of the square connecting shaft 53, and the second square sleeve 68 is connected to the magnetic force of the permanent magnet 74 through the iron block 73, so that the second square sleeve 68 does not move downward, and the lifting shaft 80 supports the lower end of the lifting plate 70 under the elastic force of the connecting spring 83. As the weight of the overflow box 7 increases, the overflow box 7 can be moved downward, and the L-shaped lifting rod 75 can be moved downward. When the first spring ejector pin 77 is moved, the first spring ejector pin 77 can gradually contact the lifting plate 70 and push the lifting plate 70 downward. At this time, the first spring ejector pin 77 can be compressed. When the overflow box 7 turns on the low-speed switch 16, the first spring ejector pin 77 can push the lifting plate 70 downward. At this time, the iron block 73 can be disconnected from the permanent magnet 74, and the second square sleeve 68 can be driven to move downward through the sixth rolling bearing 69. If the second square sleeve 68 does not fit with the square connecting rod 54 at this time, the second square sleeve 68 will fall on the upper end of the square connecting rod 54. As the second square sleeve 68 rotates, The second square sleeve 68 fits with the square connecting rod 54 and connects the second square sleeve 68 with the square connecting rod 54. When the L-shaped lifting rod 75 moves downward, the pushing platform 87 can move downward, and the pushing platform 87 can push the intercepting rod 86 downward, so that the lifting shaft 80 can move downward and compress the connecting spring 83. At this time, the positioning hole 81 moves to the side of the second spring ejector pin 82. Under the elastic force of the second spring ejector pin 82, one end of the second spring ejector pin 82 can enter the positioning hole 81, thereby limiting the lifting shaft 80. When the overflow box 7 moves upward, it can drive The L-shaped lifting rod 75 moves upward, and the L-shaped lifting rod 75 can drive the trapezoidal platform 85 to move upward. After the overflow box 7 turns on the high-speed switch 15, the moving rod 84 can be pushed to one side under the action of the inclined surface of the trapezoidal platform 85. When the straight surface end of the trapezoidal platform 85 reaches one side of the moving rod 84, the telescopic end of the second spring ejector pin 82 can be pushed backward, so that the second spring ejector pin 82 can be moved out of the positioning hole 81. Then, under the elastic force of the connecting spring 83, the lifting plate 70 and the second square sleeve 68 can be pushed upward, and the second square sleeve 68 can be disconnected from the square connecting rod 54.
