By blowing in the opposite direction, the direction between dust, dust and corn seeds is changed. Specifically, the air outlet direction of the blowing nozzle 54 is inclined to the first conveyor belt 3 or the second conveyor belt 4, respectively, and the dust is blown in the opposite direction at the same time, so that the dust extraction pipe 11 at the back is convenient to extract the dust through the fan to reduce the dust in the receiving bin 2; the top of the first conveyor belt 3 is provided with a filter screen plate 13, and the filter screen plate 13 is arranged to fit the top opening end of the receiving bin 2, and the top of the filter screen plate 13 is extended outwardly to be installed with an exhaust nozzle 12, and the exhaust nozzle 12 is connected to the dust extraction pipe 11 outwardly, and the dust extraction fan is provided inside the pipeline of the dust extraction pipe 11, and the end is connected to the dust temporary storage box 1;

[0025] A reverse dust blowing assembly 5 is also provided above the conveying end of the second conveyor belt 4, and a feed guide plate 6 connected to the feeding port of the packaging machine is connected below the conveying end, wherein the dust blowing assembly 5 is consistent with the arrangement on the first conveyor belt 3, as shown in the attached drawing for details. Figure 2 The connection between the connecting ring 51 and the blowing pipe 53 at the front and rear edges is fixed by welding, and one end of the blowing pipe 53 is connected to the air inlet duct outward, so that the blowing nozzle 54 can blow air in the reverse direction along a fixed direction;

[0026] See Figure 1 In order to facilitate installation, a first bracket 21 and a second bracket 22 are provided in the receiving bin 2. The first bracket 21 is installed on the periphery of the first conveyor belt 3 and is used to assist in the installation of the reverse dust blowing assembly 5 on the first conveyor belt 3. Specifically, the connecting ring 51 of the reverse blowing assembly 5 is obliquely installed on the first bracket 21, and one is installed at the front and the back. At the same time, the bottom of the connecting ring 51 is pressed by a pressing sheet and locked by bolts.

In order to achieve the effect of corn seeds sharing dust blowing after feeding, there are more than two pressure rollers 32 at the feeding front end of the first conveyor belt 3, and they are arranged side by side.

[0029] Working principle:

[0030] During the use of the utility model, the equipment is assembled according to Figure 1, and corn seeds are fed in through the feeding front end of the first conveyor belt (the left side is shown in the figure), and then they are flattened and gradually conveyed through the pressing rollers. The second and third pressing rollers are also set in the same way to achieve this effect, so that the corn seeds can be conveyed one by one after being flattened. It should be noted that the pressing rollers need to be adjusted to a suitable position in advance, and then when the first conveyor belt is conveyed backward, the reverse dust blowing component at the conveying end blows in the reverse direction, and the wind in the reverse direction of the conveying direction is introduced inward through the external air inlet duct, so as to separate the corn seeds. The dust on the rice seeds is removed, and the dust particles are extracted by the dust extractor and dust extraction fan above. When the corn seeds are transmitted to the rear end, due to the height difference with the second conveyor belt, they can be turned over by the effect of falling, and it is convenient to blow the dust when turning over. Because the transmission end of the second conveyor belt is also provided with a reverse dust blowing component, the secondary dust removal and dust blowing effect are achieved. At the same time, since this device is installed at the front end of the feeding of the packaging machine, it is necessary to transition. A feeding guide plate is set at the tail end of the second conveyor belt, so as to effectively deliver the corn seeds for subsequent packaging.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
