detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in the figure, a feed feeding device for individual frame cultivation of crabs includes a box body 1, a hopper 2, a feeding mechanism and a feeding mechanism arranged in the box body 1, and the hopper 2 is fixedly installed on the box body 1 Inside, the upper end of the hopper 2 is fixedly provided with a sealing cover 21, the feeding mechanism is located below the hopper 2, and the unloading mechanism is located between the hopper 2 and the feeding mechanism. The block 3 is fixedly installed on the lower end of the hopper 2, and the middle part of the connecting block 3 is provided with a feeding opening 31, which runs through one side of the connecting block 3 transversely, and the movable door 4 is located in the feeding opening 31, and the connecting block 3 is provided with a There is a horizontal guide groove 32 communicating with the feeding port 31, and the side of the movable door 4 is integrally provided with a guide block (not shown in the figure), and the guide block (not shown in the figure) is slidably matched with the guide groove 32 horizontally, and the connecting block The side end face of 3 is fixedly provided with the stopper 33 that is used to prevent dodge door 4 from popping up, and stopper 33 is positioned at the end of guide groove 32, and back-moving spring 6 is abutted between dodge door 4 and connecting block 3, and slide block 5 is arranged on One side of the dodge door 4 is used to push the dodge door 4 horizontally. A horizontal guide rail 7 is fixedly arranged in the box body 1. The slider 5 and the guide rail 7 are horizontally slidable and matched. Channel 51, the lower end of the feeding channel 51 is fixedly provided with a brush 52, the brush 52 is in contact with the bottom surface of the guide rail 7, and the box body 1 is provided with a slider horizontally moving driving device, and the slider horizontally moving driving device includes a stepping motor 8. The first connecting rod 81 and the second connecting rod 82, the stepping motor 8 is fixedly installed in the box body 1, one end of the first connecting rod 81 is fixedly connected with the drive shaft of the stepping motor 8, the first connecting rod 81 The other end is axially connected to one end of the second connecting rod 82, and the other end of the second connecting rod 82 is axially connected to the slider 5. The feeding mechanism includes a feeding pipe 9, and the bottom of the box body 1 is fixedly provided with a guide rail support 10 , the guide rail 7 is fixedly installed on the upper end of the guide rail support 10, the feeding tube 9 is fixedly arranged in the guide rail support 10, and the upper end of the feeding tube 9 runs through the bottom surface of the guide rail 7, and the lower end of the feeding tube 9 passes through the box body 1 The bottom of the bottom, the position of the feeding pipe 9 is staggered with the position of the feeding port 31 of the connecting block 3.
