The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present application; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" in the specification and claims of the present application and the above-mentioned description of the drawings and any variations thereof are intended to cover non-exclusive inclusions.
[0019] Specifically, please refer to Figures 1 to 3 , Figure 1 The overall structural diagram of the feeding device provided in the embodiment of the present application that can screen the material according to the particle size, Figure 2 This is a schematic diagram of the cross-sectional structure of the screening lower hopper provided in an embodiment of the present application. Figure 3A schematic diagram of the cross-sectional structure of the first camera device provided in the embodiment of the present application. The feeding device 100 that can screen the material according to the particle size includes a stacking bin 110, a conveying device 120, and a screening hopper 130. The input end of the conveying device 120 is located at the bottom of the stacking bin 110, and the output end of the conveying device 120 extends to the top of the screening hopper 130. The stacking bin 110 is used for stacking materials. After the stacking reaches a certain amount, the material is sent to the conveying device 120. The conveying device 120 is used to transport the material in the stacking bin 110 to the screening hopper 130 for screening. The screening hopper 130 is used to select materials of different particle sizes to be directly fed into the mixer or to be crushed and then fed into the mixer. A material partition plate 131 is provided in the inner cavity of the screening hopper 130, and the material partition plate 131 divides the inner cavity of the screening hopper 130 into a first chamber 132 and a second chamber 133. The bottoms of the first chamber 132 and the second chamber 133 are connected to each other and a material discharge channel 134 is provided. A crushing device 132a is provided in the first chamber 132. During operation, large particles of material are controlled to enter the first chamber 132, so that they are crushed into fine particles by the crushing device 132a and then enter the mixer through the material discharge channel 134. Small particles of material are controlled to enter the second chamber 133 and directly enter the material discharge channel 134 after being drained by the second chamber 133. The crushing device 132a is a prior art and will not be described in detail at this time. The top of the screening hopper 130 is connected to an inlet hopper 135, and the inlet hopper 135 can be open to avoid leakage. The top of the material separator 131 is hinged with a rotating shaft 131a, and a servo motor 131c is connected to the rotating shaft 131a, and a flap 131b is hinged at the rotating shaft 131a. During operation, the servo motor 131c can control the flap to rotate through the rotating shaft 131a. The first chamber 132 and the second chamber 133 are both provided with a first abutting end 132b and a second abutting end 133a corresponding to the flap 131b. When the flap rotates to the second abutting end 133a, the passage from the hopper 135 to the second chamber 133 will be blocked, and the material in the hopper 135 will enter the first chamber 132, and vice versa. A first camera device 140 is disposed on the top of the conveying device 120. A wiping device for wiping the first camera device 140 is disposed at the first camera device 140. Since the conveying device 120 generates some dust during the conveying process, this part of the dust will affect the camera effect after being adhered to the first camera device 140. Therefore, the wiping device wipes off the dust on the first camera device 140 to maintain the clarity of the image of the first camera device 140. The first camera device 140 is electrically connected to a PC display terminal, which is located in the central control room. The operator can monitor the size of the particle size of the material on the conveying device 120 in real time by observing the image of the first camera device 140 on the PC display terminal in the central control room.The central control room is provided with a PLC control box 150, which is electrically connected to the servo motor 131c and the crushing device 132a. The operator can further control the servo motor 131c to rotate through the PLC control box 150 according to the particle size of the monitored material, so that the flap is flipped to a suitable position for material screening, and at the same time control whether the crushing device 132a is turned on.
[0020] As can be seen from the above, in the embodiment of the present application, by setting the first camera device 140 and connecting the PC display terminal, the operator can monitor the particle size of the material at the conveying device 120 in real time and implement control according to the monitored information. By setting a flap, a servo motor 131c and a rotating shaft 131a at the material partition plate 131, the flap will control the connection state between the hopper 135 and the first chamber 132 and the second chamber 133 after rotation, and thus can control the materials of different particles to enter the first chamber 132 or the second chamber 133 respectively. By separating the screening lower hopper 130 into the first chamber 132 and the second chamber 133, and setting a crushing device 132a in the first chamber 132, when the large particle material enters the first chamber 132, the crushing device 132a is used normally, and when the small particle material enters the second chamber 133, the crushing device 132a will be in a closed state, thereby effectively avoiding the reactive power consumption of the crusher and extending the service life of the crusher.
[0021] In some embodiments, the wiping device is an electric wiping device 160, and the electric wiping device 160 is electrically connected to the PLC control box 150. In the embodiment of the present application, through the above arrangement, the operator can conveniently control the wiping device in the central control room.
[0022] In some embodiments, the first camera device 140 includes a mounting block 141, a mounting groove 141a is provided at the bottom of the mounting block 141, a camera lens 142 is installed in the mounting groove 141a, and the electric wiping device includes a rotating motor 161 arranged on the top of the mounting block 141, the rotating motor 161 is transmission-connected to a rotating shaft 162, the rotating shaft 162 extends downward to the bottom of the mounting block 141 and is connected to at least one connecting rod 163, and an elastic pad 164 is connected to the end of the connecting rod 163 away from the rotating shaft 162. In the embodiment of the present application, during the working process, when the operator observes that the view is not clear on the PC display end, the PLC control box 150 is used to control the rotating motor 161 to turn on. After the rotating motor 161 is turned on, it drives the connecting rod 163 and the elastic pad 164 to rotate. When the elastic pad 164 rotates to the bottom of the camera lens 142, the elastic pad 164 will be squeezed, and the connecting rod 163 drives the elastic pad 164 to rotate further, and the dust on the camera lens 142 will be wiped clean by the friction of the elastic pad 164.
[0023] In some embodiments, a mounting disc 162a is fixed to the bottom end of the rotating shaft 162, a plurality of connecting rods 163 are hinged on the mounting disc 162a, a mounting sleeve 162b is fixed to the middle of the rotating shaft 162, a spring assembly 162c is connected to the mounting sleeve 162b, and the other end of the spring assembly 162c is connected to the middle of the connecting rod 163. In the embodiment of the present application, through the above arrangement, when the elastic cushion 164 contacts the camera lens 142, the elastic cushion 164 is squeezed, and the spring assembly 162c is tightened and generates elastic force, so that there is sufficient pressure between the elastic cushion 164 and the camera lens 142, and at the same time, due to the adaptive adjustment of the spring assembly 162c, hard damage between the elastic cushion 164 and the camera lens 142 can be effectively avoided.
[0024] In some embodiments, the bottom of the camera lens 142 protrudes below the mounting groove 141a. In the embodiment of the present application, through the above arrangement, the bottom of the camera lens 142 is at the lowest horizontal end of the mounting block 141, and the height of the elastic pad 164 can be adjusted, so that when the elastic pad 164 passes through the rest of the mounting block 141, there is a certain gap between it and the mounting block 141, and when it passes through the area of the camera lens 142, it is processed to abut on the camera lens 142 to complete the wiping.
[0025] In some embodiments, a second camera device 170 is provided on the top of the stacking bin 110, and the second camera device 170 is electrically connected to the PLC control box 150. In the embodiment of the present application, through the above-mentioned setting, the second camera device 170 can also be connected to the corresponding PC display terminal, and then the operator can pre-judge the particle size of the material in the stacking bin 110 and the amount of the material in the stacking bin 110 according to the imaging of the second camera device 170, and thus choose whether to start the conveying device 120.
