[0026] like Figure 6 As shown, the feeding assembly 3 includes a feeding cavity 31 opened on the outside of the feeding shaft 2, the interior of the feeding cavity 31 is sealed and clamped with an adjustment plate 32 and a push plate 33, and a plurality of feeding cavities 31 are evenly distributed on the outside of the connecting cavity 4.

[0027] like Figure 1 and Figure 2 As shown, the inner walls of the loading port 7 and the lower loading port 8 are smooth, and the inner walls of the loading port 7 and the lower loading port 8 are smoothly connected to the inner wall of the loading cavity 31 at one end close to the loading shaft 2; due to the setting of the loading port 7 and the lower loading port 8, the loading shaft 2 can accurately deliver the expected amount of material to the required position through the loading cavity 31.

[0028] like Figure 6 As shown, a plurality of evenly distributed connecting grooves 34 are provided inside the feeding shaft 2, and the plurality of connecting grooves 34 correspond to the feeding chamber 31 one by one. One end of the connecting groove 34 is connected to the connecting chamber 4, and the other end of the connecting groove 34 is connected to the feeding chamber 31. A connecting pipe 35 is provided inside the connecting groove 34. Due to the provision of the connecting component 5, with the cooperation of the connecting pipe 35, the amount of air between the adjusting plate 32 and the pushing plate 33 in each feeding chamber 31 can be changed through the adjusting component 6, that is, the distance between the corresponding adjusting plate 32 and the pushing plate 33 is changed, so that the volume of the cavity for actually storing and transferring materials at the inner and outer ends of the corresponding feeding chamber 31 is changed.

[0029] like Figure 4 and Figure 5As shown, the connecting component 5 includes an adjusting chamber 51 opened on the front side of the feeding shaft 2, a limiting column 52 is arranged on the back side of the inner cavity of the adjusting chamber 51, and a through hole 53 located on the side of the limiting column 52 is opened on the side of the inner cavity of the adjusting chamber 51, and the through hole 53 is connected with one end of the connecting pipe 35, and the other end of the connecting pipe 35 is connected with the area between the feeding chamber 31 and the adjusting plate 32; due to the setting of the limiting column 52, the moving range of the piston plate 55 can be limited, which can avoid the situation where the piston plate 55 blocks the through hole 53, thereby ensuring that the movement of the piston plate 55 can always drive the air flow through the through hole 53.

[0030] like Figure 5 As shown, the internal sealing sleeve of the regulating chamber 51 is connected with a piston plate 55, and the front end of the inner cavity of the regulating chamber 51 is fixedly sleeved with a positioning plate 54; due to the setting of the positioning plate 54, it can not only avoid the situation where the piston plate 55 is separated from the regulating chamber 51, but also can effectively improve the stability of the movement of the regulating assembly 6 with the cooperation of the connecting rod 64; thereby ensuring that several piston plates 55 can move synchronously.

[0031] like Figure 4 and Figure 5 As shown, the adjustment assembly 6 includes an adjustment ring 61 arranged in front of the feeding shaft 2, the middle part of the adjustment ring 61 is threadedly sleeved with an adjustment adapter rod 62, and the back side of the adjustment adapter rod 62 is fixedly connected to the feeding shaft 2;

The transmission shaft 10 is connected to the shell 1 through a bearing sleeve, and an indicator scale is provided on the outer surface of the connecting rod 64, and the indicator scale is adapted to the positioning plate 54. Due to the setting of the indicator scale, the staff can accurately adjust the distance between the adjustment plate 32 and the push plate 33 with the cooperation of the positioning plate 54, thereby helping to improve the adjustment accuracy.

[0034] The working principle and use process of this utility model:

[0035] The lower end of the material box discharge port is connected to the top of the loading port 7, so that the material can fall continuously. When one of the loading chambers 31 rotates to the bottom of the loading port 7, the loading chamber 31 can be filled with material under the action of gravity. With the driving of the transmission shaft 10, the loading shaft 2, in cooperation with the housing 1, transmits the material to the discharge port 8 through the loading chamber 31, and finally discharges it under the action of gravity.

[0036] With the cooperation of the connecting cavity 4, the multiple feeding cavities 31 are connected to each other, and when receiving materials in a feeding cavity 31 at the top, the adjusting plate 32 and the pushing plate 33 therein are continuously pressed down to discharge air, and then the gas enters the interior of the feeding cavity 31 at the bottom through the connecting cavity 4, and then the adjusting plate 32 and the pushing plate 33 therein are moved downward and the discharge of materials is promoted;

[0037] By rotating the adjusting ring 61, the connecting rods 64 can be driven to move through the linkage ring 63 under the cooperation of the adjusting adapter rod 62, and then the piston plate 55 is driven to move along the inside of the adjusting chamber 51 under the restriction of the adjusting chamber 51 and the positioning plate 54, and at the same time, the air pressure inside the adjusting chamber 51 is changed under the restriction of the limiting column 52, and then the distance between the feeding chamber 31 and the adjusting plate 32 is changed through the through hole 53 and the connecting pipe 35, so that the cavity volume of the material actually stored in the feeding chamber 31 is changed;

[0038] Since the amount of material stored and transferred in each feeding cavity 31 is the same, the material delivery and transfer amount can be calculated based on the rotation speed of the feeding shaft 2 in the end.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
