Therefore, air holes are set in the pipeline 200. When conveying materials, the outside air enters the pipeline 200 through the air holes and infiltrates the materials, so that the materials in the pipeline 200 can obtain a reasonable air-to-material ratio, and the materials will not be affected by the pipe wall. The friction reduces the conveying speed, thereby improving the conveying efficiency.

The other end of the pipe body 202 is connected to an upper hopper (not shown in the figure). A hole 203 is formed at the bottom of the pipe bend 201 . Several holes 203 are evenly distributed in the pipe bend 201 . The angle between the two ends of the pipe bend 201 is 120°, and the diameter of the hole 203 is 10 mm. For the situation that the lower hopper is connected with the upper hopper, the number of holes 203 is 12 to 20, preferably 16.

Specifically, the hole is provided at the overflow position of the silo bottom of the pipe bend. Fig. 4 is a schematic cross-sectional structure diagram of the connection between the lower hopper and the pipeline in the second embodiment of the utility model. As shown in Fig. 4, when the granular material is poured into the lower hopper 101, the granular material 400 will appear in three types in the elbow part 201. state:

At the filling position 210 at the bottom of the bin, the granular material 400 completely fills the pipeline;

At the bottom overflow position 220, the granular material 400 only fills a part of the space in the pipeline;

At the hollow area location 230, no granular material 400 is filled at this location.

Along the direction from the lower hopper 101 to the pipe main body 202 , the bin bottom filling position 210 , the bin bottom overflow position 220 , and the hollow area position 230 are sequentially arranged in the pipe bend 201 .

In addition, for the pipe bend connected to the mixing chamber, the hole can also be set at the filling position at the bottom of the chamber.

Embodiment three

Embodiment 3 of the utility model also provides a fertilizer dispensing machine, comprising: a mixing bin and a discharging bin. The mixing bin and the discharging bin are connected by a pipeline, and the pipeline is connected to the fan. The fan generates negative pressure in the pipeline, and the material in the mixing bin is transported to the discharging bin through the pipeline for subsequent processing. In the third embodiment, the mixing chamber is the material storage device in the first embodiment.

FIG. 5 is a schematic diagram of the connection structure between the mixing bin and the pipeline in Embodiment 3 of the present utility model. As shown in FIG. 5 , the mixing bin 103 (only a partial structure is shown) is connected to the pipeline 200 . The pipeline 200 includes: a pipe bend 201 and a pipe main body 202 . The pipe bend 201 is arc-shaped, one end of the pipe bend 201 is connected to the outlet of the mixing bin 103 , and the other end of the pipe bend 201 is connected to one end of the pipe main body 202 . The other end of the pipe main body 202 is connected to a discharge bin (not shown in the figure). A hole 203 is formed at the bottom of the pipe bend 201 .
