[0023] like Figure 1 , 2 As shown in FIG. 3 , a color sorter discharge hopper with dust removal and wind pressure relief function includes a discharge hopper body 2 arranged at the front side of the end of a conveyor belt 1. The discharge hopper body 2 is divided into a qualified product hopper 21 at the front side and a defective product hopper 22 at the rear side by adjusting a baffle device 3.

[0024] A camera is arranged at the end of the conveyor belt 1 or above the defective product hopper 22 , an air path spray valve device is arranged above the discharge hopper body 2 , and a blowing system is arranged at the rear side of the defective product hopper 22 .

[0025] The baffle adjustment device 3 includes a baffle plate, the lower end of which is hinged at the connection between the qualified product hopper 21 and the defective product hopper 22 in the discharge hopper body 2. The outer walls of both sides of the discharge hopper body 2 are provided with arc-shaped adjustment holes, and adjustment bolts are installed in the arc-shaped adjustment holes. The front end of the adjustment bolt is fixed on the baffle plate, and the rear end is installed with a fixing nut. By moving the adjustment bolt in the arc-shaped adjustment hole, the rotation angle of the baffle plate can be adjusted, and then the size of the qualified product hopper 21 and the defective product hopper 22 can be adjusted, so as to adjust the degree of separation of qualified products and defective products in the material.

[0026] A dust suction chamber device 4 is disposed at the rear side of the defective product hopper 22 , and the dust suction chamber device 4 is connected to the defective product hopper 22 and the space at the rear side of the defective product hopper 22 .

[0027] The dust chamber device 4 includes an impurity chamber 5, a dust chamber 6 and a suction pipe 7. The impurity chamber 5 is provided with an impurity inlet 51 connected to the space behind the defective hopper 22 and an impurity outlet 52 connected to the interior of the defective hopper 22 at the upper and lower ends thereof. A vent 61 connected to the interior of the defective hopper 22 is provided at the lower end of the dust chamber 6. The impurity chamber 5 and the dust chamber 6 are both arranged in an inclined shape, and the angle with the vertical direction is not greater than 60°. The impurity chamber 5 is placed on the upper side of the dust chamber 6 and is installed close to the outer wall of the defective hopper 22.
