As shown in Figures 1 and 2, in order to achieve the above purpose, the present application proposes a material sorting machine. The material sorting machine includes: a frame 1, and the frame 1 is provided with A feeding station, a detection station, and a discharging station; a detection component, which is arranged on the detection station for detecting the materials entering the detection station; a feeding component, the feeding component The feeding assembly is installed on the feeding station, and the feeding assembly has a conveying surface 151 extending from the middle of the frame 1 to the detection station, or from the middle of the frame 1 to the inspection station. The edge of the frame 1 extends into the conveying surface 151 of the detection station; the discharge port is located at the discharge station.

In this embodiment, the material sorting machine proposed in this embodiment can be used for sorting ores, grains, waste recycling products (such as waste household appliances), etc., and specifically includes a rack 11, a feeding component, and a detection component. The rack 11 is The installation basis of the feeding component and the detection component. The feeding component is used to transfer the material to the detection station for detection by the detection component installed on the detection station. The feeding station, the detection station and the unloading station are set in sequence at the bottom. The material enters the detection station from the feeding station, and then flows out of the material sorting machine from the discharging station. There is a detection component on the detection station, and a discharge port on the unloading station. This setting method enables the material to be fed from the top of the material sorting machine, saving horizontal space. In one embodiment, a discharge port is provided on the blanking station, wherein the blanking station is located below the detection station and at least partially within the projection area of the detection station. Therefore, at least part of the discharge port 18 is located in the projection area of the inspection station, and the output end of the feeding assembly faces the inspection station. In this setting, the material leaves the output end of the feeding assembly and passes through the inspection station. The bits will drop directly into the discharge port 18. During this process, the detection component will detect the material passing between the transmitting end 21 and the receiving end 22 of the detecting component. In this embodiment, the detection component is arranged on the detection station, and the transmitting end 21 and the receiving end 22 of the detection component are arranged at intervals to form a detection space. The detection space is located above the discharge station, and after the material is separated from the output end of the feeding component After passing through the detection space, it enters the discharge port 18 at the unloading station. In this embodiment, the material falls free from the output end of the feeding component. When it reaches the detection space during the falling process, the ray emitted by the transmitting end 21 to the receiving end 22 passes through the material and is received by the receiving end 22, passing through the material. There will be a certain degree of attenuation in the rays of the material sorting machine. The attenuation of rays caused by different minerals is different. The receiving end 22 is electrically connected to the central control device of the material sorting machine, and the received rays can be sent to the central control device for analysis. Thereby, the minerality of the material is obtained. The mineral identification of the material here includes the identification of the content of the target substance and the identification of the substance type, such as metal, plastic, etc. In the sorting of ore, the target material can be the ore containing the target metal or the ore with the target metal content exceeding the preset value. When recycling waste items, the crushed items, such as metal and plastic, can be processed Classification. It should be pointed out that after the material is irradiated with radiation, it will also emit fluorescent electrons, and the image of the material can be obtained through the fluorescent camera. Of course, in other embodiments, the detection component may also be a high-frequency camera, a laser-induced device, or the like.

The conveying surface 151 extends from the middle of the rack 1 to the detection station, and can also extend from the top edge of the rack 1 to the detection station, and the height of the conveying surface 151 gradually decreases from the top of the rack 1 to the detection station. The material slides up and down the conveying surface 151, and enters the detection station after leaving the conveying surface 151. The material will gradually spread out during the process of sliding up and down the conveying surface 151, so as to avoid falling into the detection station in piles and affect the detection accuracy. The way that the materials gradually spread out during the sliding process can be realized by vibrating the conveying surface 151 by the vibrator 16, or the inclined surface area of the conveying surface 151 can be increased sequentially from top to bottom so that the materials can be dispersed during the sliding process, for example, Conical bevel. In another embodiment, the conveying surface 151 can also be set horizontally. At this time, the conveying surface 151 is driven by a linear feeder (not shown in the figure) to drive the material on the conveying surface 151 to the detection station. The arrangement of the conical inclined surface of the conveying surface 151 has a larger conveying area than the traditional horizontal conveying way, for example, the entire surface of the conical conveying surface can be used for conveying materials, which has Wider effective feeding surface, in the same horizontal section, the effective feeding area of the conical transmission surface is 3.14 times that of the horizontal transmission surface of the same width, which can greatly improve the sorting efficiency of the material sorting machine.

The transmission surface 151 may be a metal plate surface structure or a mesh surface structure, which is specifically determined according to the equipment for realizing the sorting.

Since the material falls free from the output end of the feeding component, the detection component completes the detection of the material during the falling process of the material. This arrangement from top to bottom can avoid setting the conveyor belt in the horizontal direction to transmit the material, which can reduce the The volume of the equipment is more conducive to the arrangement of equipment on the sorting site.

In one embodiment, the rack 1 is provided with a chute inclined from the middle of the rack 1 to the detection station, and the conveying surface 151 is the bottom of the chute. There can be a plurality of chutes, and in this case, they can be arranged at the top of the rack 1 at intervals, for example, arranged in a circular array or arranged in a linear array. When the conveying surface 151 is a conical inclined surface, the conical surface can be a circular arc conical surface or a conical surface enclosed by multiple planes, such as a triangular conical surface enclosed by three planes or four The trapezoidal conical surface formed by the plane enclosure, at this time, the material can slide from any direction, correspondingly, the material that slides from any direction will enter the detection station. In an optional embodiment, the material sorting machine may include multiple sets of the feeding components and multiple sets of the detection components, and the multiple sets of the feeding components and the multiple sets of the discharging components are in one-to-one correspondence. They are distributed at intervals along the frame 11 , and the distribution direction may be spaced along a straight line, or may be arrayed along the circumferential direction of the frame 11 , which may be determined according to the setting of the conveying surface 151 . For example, when the plurality of conveying surfaces 151 are arranged in a straight line, the plurality of feeding components and the plurality of detecting components can be arranged in a one-to-one correspondence along the linear extension direction of the frame 11 at intervals. When the conveying surface 151 is a tapered surface At this time, a plurality of feeding components and a plurality of detecting components can be arranged in a circumferential array of the frame 11 in one-to-one correspondence. A feeding port 14 is opened on the top of the frame 1, and part of the inclined surface of the conveying surface 151 is exposed. In the feeding port 14, it is convenient to place the material on the conveying surface 151. This way of setting up multiple sets of feeding components and multiple sets of detection components in one-to-one correspondence on the same rack 11 can realize the sorting of a large number of materials at the same time. When there are four sets of feeding devices and four sets of detection devices corresponding to each other, it can be understood that the number of feeding devices and detection devices is not limited to the four groups shown in the figure, but can also be set to 3 groups as required. , 6 groups, etc., can sort a large number of materials at the same time, which greatly improves the efficiency of material sorting.

The feeding assembly further includes a vibrator 16, the vibrator 16 is arranged on the frame 1, and the power output end of the vibrator 16 is connected to the conveying surface 151, and the conveying surface 151 is close to the conveying surface 151. An elastic support 153 is connected to one end of the detection station. When the vibrator 16 drives the conveying surface 151 to vibrate, the materials can be dispersed evenly. Therefore, the conveying surface 151 can be connected to the output end of the vibrator 16, and the vibrator 16 drives the conveying surface 151 to vibrate, dispersing the vibration of the materials on the conveying surface 151. Open to avoid the situation that the ray passes through two materials at the same time after the material enters the detection station, so as to ensure the accuracy of the detection. The frame 1 includes an upper support portion 11 , a middle support portion 12 and a lower support portion 13 connected in sequence, and the middle support portion 12 has a bracket 17 for supporting the conveying surface 151 (as shown in FIG. 2 ) One end of the elastic support member 153 is connected to the bracket 17 , the other end is connected to the conveying surface 151 , and the emission end is arranged in the bracket 17 . In this embodiment, the vibrator 16 can be installed on the upper support part 11, or can also be installed in the middle support part 12 when there is enough installation space in the middle support part 12, but the power output end of the vibrator 16 is connected to On the conveying surface 151, the power output end of the vibrator 16 can be a cam (not marked in the figure) connected to the motor. The end of the conveying surface 151 close to the middle of the frame 1 is provided with an inner hollow boss 152. The cam Located in the cavity of the boss 152 , the rotation of the cam will interfere with the inner wall of the boss 152 , causing the entire conveying surface 151 to vibrate. The elastic support 153 disposed between the conveying surface 151 and the bracket 17 may be a spring or a shock absorber.

The middle support part 12 includes an outer bracket 121 and an inner bracket 122, a drop channel 10 is formed between the outer bracket 121 and the inner bracket 122, the discharge port is located in the drop channel 10, and the receiving end The emitting end and the emitting end are respectively located on both sides of the falling channel 10. When the material passes between the emitting end and the receiving end, the ray emitted by the emitting end can pass through to the receiving end. The transmitting end 21 can be set on the built-in support 13 and the receiving end 22 can be set on the external support 12 , or the transmitting end 21 can be set on the external support 12 and the receiving end 22 can be set on the built-in support 13 . During the falling process of the material, it will pass through the transmitting end 21 and the receiving end 22, and the ray emitted by the transmitting end 21 will pass through the material and be received by the receiving end 22, so it can be concluded that the material is the target according to the analysis of the central control device (not marked in the figure). Item or non-target item. The material outlet 18 specifically includes a first material outlet 181 and a second material outlet 182.
