To facilitate understanding, the following further explains the operation principle of the color sorter 100 in the prior art, as shown in fig. 1 and fig. 2, a material 3 to be sorted is sorted by the color sorter 100, when the material to be sorted 3 occupies a relatively small area, the material 3 to be sorted enters the color sorter 100 through the hopper 1, and under the vibration action of the vibrator 2, the material 3 to be sorted slowly falls into the chute 4, the material 3 to be sorted falls down along the chute 4 and enters the sorting box 5, under the cooperation of the light source 6/light source 11, the camera 8/camera 10, the background plate 7/background plate 9 and the like arranged in the sorting box 5, whether the material 3 to be sorted passing through the viewpoint 12 meets the requirement is detected and judged, if yes, the material 3 to be sorted will enter the finished product hopper 14 in a free-falling state along the original motion trajectory, if the sorting machine does not meet the requirement, the materials 3 to be sorted deviate from the original motion track under the blowing action of the high-pressure blowing valve 13 and enter the rejecting hopper 15, and therefore the sorting of the materials 3 to be sorted is achieved through the action of the color sorter 100.

It should be noted that when the ratio of the materials to be sorted 3 is large, the other materials are kept unchanged, which is the same as the above working principle, but the product hopper 14 and the sorting hopper 15 can be exchanged to save high pressure gas and sorting cost. After the finished product hopper 14 and the rejecting hopper 15 are exchanged, whether the materials 3 to be sorted passing through the observation point 12 meet the requirements or not is detected and judged, if not, the materials 3 to be sorted can enter the finished product hopper 14 in a free falling state along the original motion track, and if so, the materials 3 to be sorted can deviate from the original motion track under the blowing action of the high-pressure spray valve 13 and enter the rejecting hopper 15.

It should be noted that, first, the color sorter 200 includes the discharge hopper 20, which means that the present application is mainly improved on the discharge hopper 20, and the components or parts required by the remaining color sorters 200 to achieve sorting function, for example: the hopper 1, shaker 2, chute 4, sorting bin 5, light source 6/light source 11, background plate 7/background plate 9, camera 8/camera 10, high pressure spray valve 13, etc. may all be designed with reference to components or parts of the prior art color sorter 100.

Secondly, the discharging hopper 20 refers to a hopper into which the material 3 to be sorted enters after deviating from the original movement track under the blowing action of the high-pressure injection valve 13, and does not limit the discharging hopper 20 to be a rejecting hopper 15 or a finished product hopper 14, and the material refers to a material deviating from the original free-falling movement track under the blowing action of the high-pressure injection valve 13 and does not limit the material to be a rejecting material or a finished product material.

Thirdly, the discharging hopper 20 comprises a shell and a blowing device 30, the shell is a hollow structure with an opening at the top, the opening is used for materials to pass through and enter the shell, and an accommodating cavity formed by the hollow structure is used for storing the materials. The shape of the housing is not particularly limited, and it is sufficient that the top of the housing has an opening so that the material can enter the housing through the opening.

Fourthly, as can be seen from the background art and the above description of the operation principle of the color sorter 100 in the prior art, when the material enters the shell of the discharge hopper 20, the material will impact the sidewall of the shell at a certain movement speed Z and then fall into the bottom of the shell under the blowing action of the high-pressure injection valve 13. The moving speed Z of the materials impacting the side wall of the shell can be decomposed in the horizontal direction and the vertical direction to be decomposed into a moving speed X in the horizontal direction and a moving speed Y in the vertical direction.

Based on this, the application provides a go out hopper 20, still including setting up on the casing lateral wall and can follow the blast apparatus 30 that the horizontal direction was bloied, aim at through blast apparatus 30's effect down for horizontal direction's velocity of motion X can be weakened when the material gets into the casing, reduces to 0 even, thereby avoids the material to collide with a play hopper 20, and then avoids taking place the broken phenomenon of material and the damage phenomenon of going out hopper 20.

Therefore, the rotation speed of the blowing device 30 is not particularly limited, and it is only necessary that the material does not hit the side wall of the housing.

In summary, the discharge hopper 20 comprises a housing and a blowing device 30, the housing is a hollow structure with an opening at the top, the opening is used for materials to pass through and enter the housing, and an accommodating cavity formed by the hollow structure is used for storing the materials. When the material enters the shell of the discharge hopper 20, the material will impact the side wall of the shell at a certain moving speed Z and then fall into the bottom of the shell under the blowing action of the high-pressure blow valve 13. The moving speed Z of the materials impacting the side wall of the shell can be decomposed in the horizontal direction and the vertical direction to be decomposed into a moving speed X in the horizontal direction and a moving speed Y in the vertical direction. Based on this, the application provides a go out hopper 20, still including setting up on the casing lateral wall and can follow the blast apparatus 30 that the horizontal direction was bloied, aim at through blast apparatus 30's effect down for horizontal direction's velocity of motion X can be weakened when the material gets into the casing, reduces to 0 even, thereby avoids the material to collide with a play hopper 20, and then avoids taking place the broken phenomenon of material and the damage phenomenon of going out hopper 20.

In consideration of the testing link process, from the beginning, the test is performed, before the rotation speed of the blowing device 30 is adjusted to prevent the material from colliding with the discharge hopper 20, the material still has the movement speed X in the horizontal direction, and the collision between the material and the side wall of the housing may occur. Because the fan 32 is covered in the cover 31, in order to enable the airflow generated by the rotation of the fan 32 to flow out, the cover 31 is provided with a plurality of first air outlet holes 33, and the plurality of first air outlet holes 33 are at least located on one side of the cover 31 departing from the side wall of the housing.
