Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The rotating assembly includes a gear 21 , which is rotatably connected to the front surface of the feed hopper 2 . The gear 21 is supported by the feed hopper 2 and is fixedly connected to the front surface of the lower barrel 24 .

[0034] Reference Figure 1 , Figure 3 , Figure 4 The left side of the feed hopper 2 is provided with an adjustment component, which includes a slide groove 37. The slide groove 37 provides movement for the guide block 3. The slide groove 37 is opened on the left side of the feed hopper 2. The right inner wall of the slide groove 37 is provided with a circular groove 34 and multiple groups are opened. The position of the guide block 3 can be adjusted by cooperating with the round rod 36 through the multiple groups of circular grooves 34. At the same time, the speed of material discharge can be controlled by adjusting the size of the opening of the bottom plate 32. The left side of the feed hopper 2 is slidably connected with the guide block 3. The guide block 3 can drive the guide frame 31 to move, so that the guide rod 33 moves downward while sliding on the inner wall of the guide frame 31. The right side of the guide block 3 is slidably connected to the inner wall of the slide groove 37. The left side of the guide block 3 is penetrated and slidably connected with the round rod 36.

[0035] Furthermore, the round rod 36 is elastically connected to the guide block 3 through the spring 35. Pulling the round rod 36 out of the circular groove 34 can release the limit of the guide block 3 and stretch the spring 35 at the same time. At this time, the size of the opening of the bottom plate 32 can be adjusted by adjusting the position of the guide block 3, so as to control the feeding speed. When the adjustment is completed, the reverse force of the spring 35 being squeezed can drive the round rod 36 to reset and move, and slide into the circular groove 34 to limit the guide block 3, guide frame 31 and bottom plate 32.

[0036] Furthermore, the round rod 36 slides on the inner wall of the circular groove 34, which can limit the guide block 3. The bottom end of the guide block 3 is fixedly connected to the guide frame 31, and the guide frame 31 can drive the two groups of guide rods 33 to move so that the bottom plate 32 can be opened. The inner wall of the guide frame 31 is slidably connected to the guide rods 33 and two groups are provided. The two groups of guide rods 33 drive the two groups of bottom plates 32 to rotate and open. The lower end of the front surface of the feed hopper 2 is hinged with the bottom plate 32 and two groups are provided. The guide rod 33 is fixedly connected to the left side of the bottom plate 32, and the rotation and opening size of the two groups of bottom plates 32 can be controlled to control the speed of material discharge.

[0037] Reference Figure 1 - Figure 2 A gear ring 22 is fixedly connected to the top of the machine body 1, and the gear 21 is meshed with the gear ring 22. The meshing of the gear 21 and the gear ring 22 allows the feed hopper 2 to rotate while the discharge barrel 24 can rotate, so that the feed hopper 2 can rotate to evenly discharge the material into the machine body 1, preventing the material from piling up in one position, thereby improving the mixing effect and applicability.

[0038] Working principle: When in use, after pouring the material into the feed trough 23, the round rod 36 is pulled out of the round groove 34 to stretch the spring 35 outside the guide block 3, and the guide block 3 is moved downward to drive the guide frame 31 to move downward, and at the same time drive the guide rod 33 to move downward while sliding on the inner wall of the guide frame 31, and the two groups of guide rods 33 move downward to drive the two groups of bottom plates 32 to rotate and open, so that the material can be fed downward from the gap between the two groups of bottom plates 32 through the bottom plate 32, and the feeding speed can be controlled by controlling the gap between the two groups of bottom plates 32. When the adjustment is completed, the reverse force of the spring 35 being squeezed can cause the round rod 36 to reset and slide into the round groove 34 to limit the guide block 3, the guide frame 31, and the two groups of bottom plates 32. At this time, the feeding speed can be adjusted.

[0039] When feeding, the motor is started to drive the rotating rod 5 and the connecting block 4 to rotate, and at the same time drive the two sets of feeding hoppers 2 to rotate. The rotation of the feeding hopper 2 drives the gear 21 to rotate around the center point of the rotating rod 5. The gear 21 is engaged with the gear ring 22, so that the gear 21 can rotate on its own, and at the same time drive the discharge barrel 24 to rotate on its own. The rotation of the feeding hopper 2 and the coordination of the discharge barrel 24 can make the material rotate evenly around the center point of the rotating rod 5 while being discharged. At this time, the material can be evenly discharged into the machine body 1 while being divided, thereby improving the applicability of the device.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
