Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, a tea sieving machine includes a box 1, a feeding hopper 2 is provided at the upper end of the box 1, and the feeding hopper 2 is communicated with a feeding port 3 of the box 1. Two material stirring rollers 4 are arranged in the box body 1 and below the feed inlet 3, the material stirring rollers 4 are driven by a motor to rotate, and the material stirring rollers 4 rotate towards the central line of the two material stirring rollers 4. The outer wall of the material poking roller 4 is evenly provided with material poking blades 5, and the material poking blades 5 on the two material poking rollers 4 are respectively arranged in a staggered mode.
A dust removal channel 6 is arranged below the material stirring rollers 4, and the dust removal channel 6 is arranged right below the center line of the two material stirring rollers 4. A first dust outlet hole 7 is formed in the inner wall of the dust removing channel 6, and an air outlet nozzle 8 is fixed on the inner wall of the dust removing channel 6 and opposite to the first dust outlet hole 7. The air outlet spray heads 8 are arranged in two groups, one group of air outlet spray heads 8 positioned above face the first dust outlet hole 7, and the other group of air outlet spray heads 8 incline to face upwards. And an air blower 9 is arranged on one side of the dust removal channel 6, and the air blower 9 is connected with an air outlet nozzle 8 through an air inlet pipe 10. The other side of the dust removal channel 6 is provided with a dust removal box 11, one end of the dust removal box 11 close to the dust removal channel 6 is provided with a dust outlet hole II 12, and the dust outlet hole II 12 is communicated with the dust outlet hole I7. The top is equipped with water smoke shower nozzle 13 in the dust removal case 11, is equipped with water tank 14 outside the box 1, and water tank 14 is connected with water pump 15, and water pump 15 is connected with inlet tube 16, and inlet tube 16 stretches into the dust removal case 11 and is connected with water smoke shower nozzle 13, is equipped with the spillway hole 17 on the dust removal case 11.
