[0017] The beneficial effects of the present invention are: 1) When the present invention is working, it can realize the continuous multi-station feeding of pellet feed for animal husbandry. By realizing the multi-station continuous feeding function, the non-stop operation of the device is realized, thereby improving the quantitative feeding efficiency of the device. In addition, when the device is in quantitative feeding control, the self-cleaning maintenance of the feeding weighing mechanism can be realized and the residual rate of feed particles on the inner wall of the weighing mechanism can be effectively reduced, thereby effectively maintaining the weighing accuracy of the weighing mechanism.

[0018] 2) In the present invention, when the weighing component is not in the corresponding position with the discharge pipe, the driven bevel gear is not connected with the driving bevel gear, the cam and the vibrating frame remain stationary, and when the discharge pipe is discharging, the material discharged from the discharge pipe is sent to the rotary weighing cylinder directly below the discharge pipe, and when the vibrating frame remains stationary, the material blocking cone head blocks the corrugated conduit, so that the rotary weighing cylinder can carry out the feed weighing operation. At the same time, during the entire discharge process, the outer gear ring rotates at a set speed. After the outer gear ring rotates, it drives the rotary weighing cylinder to rotate continuously. Through the continuous rotation of the rotary weighing cylinder, the residual rate of feed on the inner wall of the rotary weighing cylinder is effectively reduced, thereby effectively improving the discharge cleanliness of the rotary weighing cylinder and reducing the residual rate of feed on the inner wall of the rotary weighing cylinder. When the feedback value of the pressure sensor in the weighing component below the discharge pipe reaches the set value, the transfer motor drives the station transfer frame to rotate 90° clockwise, thereby realizing the station conversion.

[0019] 3) In the present invention, when a certain weighing component moves to the position just above the discharge pipe, the active bevel gear is connected with the driven bevel gear on the weighing component. After the active bevel gear is connected with the driven bevel gear on the weighing component, the convex shaft drives the vibration guide cam to rotate at a set speed. After the convex shaft rotates, it drives the vibration frame and the rotary weighing cylinder to move back and forth within the set frequency. When the rotary weighing cylinder moves back and forth within the set frequency, the relative position of the rotary weighing cylinder and the material-blocking cone head is changed back and forth. By changing the relative position of the rotary weighing cylinder and the material-blocking cone head, the material-blocking cone head periodically loses its blocking effect on the corrugated conduit, and the quantitative feed weighed in the rotary weighing cylinder can be discharged through the discharge pipe.

[0025] The weighing component includes a bracket 16 mounted on the station rotating frame 11, and a vibrating frame 17 is slidably connected to the bracket 16. The vibrating frame 17 is provided with a vibration guide component adapted to the active bevel gear 14; The vibration guide assembly includes a follower vibration wheel 26 rotatably connected to the vibration material frame 17 and a convex shaft 27 rotatably connected to the bracket 16. A follower bevel gear 28 and a guide vibration cam 29 are respectively installed on the convex shaft 27. The guide vibration cam 29 is adaptively connected to the follower vibration wheel 26, and the follower bevel gear 28 is adaptively connected to the active bevel gear 14. A return spring 30 limited by the bracket 16 is installed on the bottom surface of the vibration material frame 17; A weighing ring 18 is provided above the vibrating frame 17, and a group of pressure sensors 19 are installed between the weighing ring 18 and the vibrating frame 17. The data end of the pressure sensor 19 is connected to the single chip microcomputer 43. The inner wall of the weighing ring 18 is rotatably mounted with a rotary weighing cylinder 20 with an open top, and a collecting ring 21 is provided on the bracket 16 and at a position corresponding to the lower part of the rotary weighing cylinder 20, and the bottom surface of the collecting ring 21 is slidably fitted with the baffle plate 5; A corrugated conduit 22 is rotatably connected between the rotary weighing cylinder 20 and the collecting ring 21. A valve stem 23 is fixedly installed on the inner wall of the collecting ring 21. A material-blocking cone head 24 is installed on the top of the valve stem 23.
