[0021] Specifically, please refer to Figures 1 to 3 , Figure 1 It is a schematic diagram of the overall cross-sectional structure of the hulling device for miscellaneous grain seeds provided by the embodiment of the present application, Figure 2 Figure 1 An enlarged view at A, Figure 3This is a schematic diagram of a partial cross-section structure at the uniform distribution component provided by the embodiments of the present application. The hulling device 100 for miscellaneous grain seeds includes a hulling box 110 and a impurity collection box 120 arranged in parallel. The hulling box 110 is a prior art and is not the core inventive point of the present application, so it will not be elaborated here. The impurity collection box 120 is used to collect various impurities in the mixed miscellaneous grain seeds. A roller assembly 111 for squeezing and hulling the miscellaneous grain seeds is arranged in the hulling box 110. After the seeds are decontaminated, they will fall to the roller assembly 111 and be hulled by the extrusion of the roller assembly 111. A feeding table 130 is commonly supported at the tops of the hulling box 110 and the impurity collection box 120. A feeding chute 131 is arranged at the top of the feeding table 130, and the miscellaneous grain seeds to be hulled can be put into the feeding chute 131 for feeding. A disk-shaped buffer bin 132 is connected to the bottom of the feeding chute 131. The bottom of the buffer bin 132 is connected to the hulling box 110. A uniform distribution component 133 for driving the material to fall evenly is arranged in the buffer bin 132. The miscellaneous grain seeds and a small amount of impurities in the feeding chute 131 will enter the buffer bin 132 from the feeding chute 131 and slowly and evenly fall into the hulling box 110 under the action of the uniform distribution component 133. A dust-proof plate 140 is connected to the side wall shared by the hulling box 110 and the impurity collection box 120. The other end of the dust-proof plate 140 is inclined upward and extends into the hulling box 110. The angle of the dust-proof plate 140 can be set according to the actual situation. The material in the feeding chute 131 will fall onto the middle part of the dust-proof plate 140. A diversion pipe 132a is connected to the bottom of the buffer bin 132. The bottom end of the diversion pipe 132a extends to the middle part of the dust-proof plate 140. The setting of the diversion pipe 132a ensures that the material in the aggregate chute falls accurately onto the dust-proof plate 140 in a relatively concentrated manner. A blower 150 is arranged at the top of the impurity collection box 120. The air outlet of the blower 150 faces the dust-proof plate 140. The blower 150 is used to blow air towards the dust-proof plate 140 and to its top side. Under the action of the air flow, the heavier impurities such as gravel in the material falling from the diversion pipe 132a will fall onto the dust-proof plate 140 and finally fall into the impurity collection box 120 through the downward sliding on the dust-proof plate 140 to complete the collection, while the lighter miscellaneous grain seeds will be blown up by the air flow and finally fall into the hulling box 110 to be hulled by the roller assembly 111.

[0022] As described above, in the embodiments of the present application, by providing a buffer bin 132 and arranging a uniform distribution component 133 inside the buffer bin 132, the material can be evenly and stably dropped onto the dust-raising plate 140. The dust-raising plate 140 cooperates with the hair dryer 150, and the hair dryer 150 blows air to one side of the top of the dust-raising plate 140, so that the air flow can act on the material on the top of the dust-raising plate 140. According to the characteristics that impurities are heavier in texture and seeds are lighter in texture, the two are separated, which can effectively guarantee the quality of the later miscellaneous grains and avoid damage to the internal components of the hulling machine caused by impurities. In the embodiments of the present application, by providing a impurity collection box 120 and making the impurity collection box 120 located at the lower end of the dust-raising plate 140, the separated impurities can be collected into the impurity collection box 120 for convenient secondary separation later.

[0023] In some embodiments, the uniform distribution component 133 includes a rotating cylinder 133b connected to a driving component 133a. A plurality of baffle plates 133c are connected to the outer periphery of the rotating cylinder 133b. The plurality of baffle plates 133c are arranged in a circular array on the outer periphery of the rotating cylinder 133b. A V-shaped loading groove 133d is jointly formed between two adjacent baffle plates 133c and the rotating cylinder 133b. The embodiments of the present application provide a specific setting manner of the uniform distribution component 133. The driving component 133a can be a motor, etc. When the driving component 133a drives the rotating cylinder 133b to rotate, the baffle plates 133c rotate together with the rotating cylinder 133b. Then, the material in the feeding chute 131 will enter the loading groove 133d formed by the baffle plates 133c and the rotating cylinder 133b. As the rotating cylinder 133b and the baffle plates 133c continue to rotate, the loading groove 133d will rotate to the lower part. At this time, the material in the loading groove 133d will fall downward onto the dust-raising plate 140 under the action of gravity, and the material can be evenly dropped during the whole process. Specifically, during the working process, the feeding speed can be controlled by controlling the rotation frequency of the rotating cylinder 133b.

[0024] In some embodiments, an air outlet cylinder 160 is included. The bottom of the air outlet cylinder 160 is communicated with the hulling box 110, and the top of the air outlet cylinder 160 penetrates and extends to the top of the feeding table 130. In the embodiments of the present application, by providing the air outlet cylinder 160, the air pressure inside the cavity of the equipment is maintained stable, and the flow direction of the internal air flow of the equipment is made more reasonable, so that the relevant operations can be completed more efficiently. And when part of the material enters the air outlet cylinder 160, due to the certain height of the air outlet cylinder 160, this part of the material will fall back into the hulling box 110 under the action of gravity.

[0025] In some embodiments, the air outlet cylinder 160 is a telescopic air outlet cylinder 160. In the embodiments of the present application, through the above setting, it is convenient to adjust the height of the air outlet cylinder 160 in real time according to the type of the material, so as to ensure that the material will not escape to the outside of the equipment along the air outlet cylinder.

[0026] In some embodiments, the air outlet cylinder 160 includes a first pipe body 161 and a second pipe body 162. The first pipe body 161 communicates with the shelling box 110. The second pipe body 162 is sleeved on the outer periphery of the first pipe body 161. An adjusting bolt 163 is screwed on the second pipe body 162. One end of the adjusting bolt 163 penetrates through the second pipe body 162 and abuts against the outer periphery of the first pipe body 161. The embodiments of the present application provide a specific setting manner of the air outlet cylinder 160. Specifically, during the working process, when it is necessary to adjust the height of the air outlet cylinder 160, after rotating the adjusting bolt 163, stretch or compress the second pipe body 162 downward to a suitable position, and then re-tighten the adjustment so that the adjusting bolt 163 abuts against the first pipe body 161 again.

[0027] In some embodiments, there are multiple adjusting bolts 163, and the multiple adjusting bolts 163 are spaced along the circumferential direction of the second pipe body 162. In the embodiments of the present application, through the above settings, the fixing of the first pipe body 161 and the second pipe body 162 by the adjusting bolts 163 is more stable.

[0028] In some embodiments, a receiving groove 170 is provided at the bottom of the impurity collection box 120. A drawer assembly 171 is slidably arranged in the receiving groove 170. One side of the drawer assembly 171 extends to the outside of the receiving groove 170 and is connected with a handle. In the embodiments of the present application, through the above settings, the impurities collected in the impurity collection box 120 will further fall into the drawer assembly 171 in the receiving groove 170, which is convenient for subsequent operators to take it out conveniently.
