Description

Technical Field

[0001] The utility model belongs to the technical field of ore screening, and particularly relates to a crawler-type ore color sorter. Background Art

[0002] A color sorter is a device that automatically sorts out different-color particles in granular materials based on the differences in the optical properties of the materials by using optoelectronic detection technology. The crawler-type ore color sorter is used for screening ore-related materials. Before screening quartz stone with a crawler-type quartz stone color sorter, the quartz stone needs to be crushed into an appropriate size to form quartz sand, and then the surface of the quartz sand is cleaned by a cleaning device so that the crawler-type quartz stone color sorter can accurately judge the color of the quartz sand and improve the screening accuracy.

[0003] However, there may be a situation where there is still water remaining on the surface of some styles of quartz sand after cleaning. Since the quartz sand is small in volume and light in weight at this time, the water on the surface of the quartz sand may cause the quartz sand to stick to the miscellaneous stones, thus affecting the screening effect of the color sorter.

[0004] Therefore, a crawler-type ore color sorter is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a crawler-type ore color sorter, so as to overcome the defect that the existing crawler-type ore color sorter is prone to poor screening accuracy when screening materials that are adhered together after cleaning. The specific technical solutions are as follows:

[0006] A crawler-type ore color sorter includes a hopper, a guide disk, a support frame, a rotating motor, a transmission component, a conveyor belt, a color sorter body and a frame. The color sorter body is located on one side of the frame. The hopper is installed at one end of the frame far away from the color sorter body. The support frame is installed on the frame and is located between the color sorter body and the hopper. The conveyor belt is installed on the support frame. A guide disk is installed at the discharge port of the hopper for guiding materials to fall onto the conveyor belt. The rotating motor is connected to the conveyor belt through the transmission component. The color sorter body is provided with a feed port corresponding to one end of the conveyor belt;

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0024] refer to Figure 1 A crawler type ore color sorter, comprising a hopper 2, a guide plate 3, a support frame 4, a rotating motor, a transmission assembly, a conveyor belt 5, a color sorter body 1 and a frame 6, wherein the color sorter body 1 is located on one side of the frame 6, the hopper 2 is mounted on one end of the frame 6 away from the color sorter body 1, the support frame 4 is mounted on the frame 6 and is located between the color sorter body 1 and the hopper 2, the conveyor belt 5 is mounted on the support frame 4, a guide plate 3 is mounted at the discharge port of the hopper 2 for guiding the material to fall onto the conveyor belt 5, the rotating motor is connected to the conveyor belt 5 through the transmission assembly, and the color sorter body 1 is provided with a feed port 101 corresponding to one end of the conveyor belt 5;

[0025] It also includes a drying unit, which includes an air duct 7, a heating rod 8 and a box body 9. The box body 9 is installed on the top of the support frame 4. An opening 901 is provided on one side of the box body 9 close to the conveyor belt 5. The heating rods 8 are arranged in an array inside the box body 9. One end of the air duct 7 is connected to the side of the box body 9 far away from the opening 901. Materials enter from the hopper 2 and then roll onto the conveyor belt 5 through the guiding disc 3. When the materials move under the action of the conveyor belt 5 to directly below the box body 9, the heating rod 8 heats the air flow in the air duct 7, and then the hot air directly acts on the surface of the materials to dry the surface of the materials. When there is no surface tension of water on the surface of the materials, the materials will not adhere together, thus ensuring the screening accuracy of the color sorter body 1 and avoiding misjudgment of the color sorter body 1. And some materials may be sticky on the surface when they are wet, and the drying unit can eliminate this situation. The dried materials will enter the color sorter body 1 through the feed port 101 under the drive of the conveyor belt 5 for screening.

[0026] Reference Figure 2 , the shunt unit includes a cylinder 10, a first filter screen 11 and a second filter screen 12. One end of the cylinder 10 is connected to the side of the box body 9 far away from the opening 901, the other end of the cylinder 10 is connected to the air duct 7, the first filter screen 11 is installed inside the cylinder 10, and the second filter screen 12 is installed at the opening 901 of the box body 9. When the air flow encounters the first filter screen 11 and the second filter screen 12, due to the limited size of the filter holes of the filter screen, the air flow will be blocked, so the air flow will automatically spread in other directions, resulting in a similar overall filtered air flow in the end. Thereby reducing the acting force and acting uniformity of the air flow on the materials, uniformly drying the materials on the premise of avoiding the materials from being blown and rolling, improving the drying effect, and at the same time ensuring that the conveyor belt 5 can transport the materials normally.

[0027] A plurality of exhaust holes 13 are arranged in an array on the conveyor belt 5. The diameter of the exhaust holes 13 is 1 mm. The size of the materials of the color sorter is generally more than 2 mm. Therefore, the 1-mm exhaust holes 13 can discharge the air flow blown out from the opening 901 of the box body 9 from the exhaust holes 13 on the premise of ensuring that the materials will not break away from the conveyor belt 5, avoiding the generation of a lateral air flow after the air flow encounters the conveyor belt 5 and driving the materials to move.

[0028] One side of the box body 9 is rotatably installed on the support frame 4 through a hinge 14, and a handle 15 is installed on the outer side wall of the box body 9 away from the hinge 14. The box body 9 is made in an openable form, which is convenient for subsequent maintenance and repair.

[0029] A vibration motor is installed on the support frame 4. The materials that adhere together may not automatically separate after drying, so a vibration motor is needed to vibrate and disperse the materials that stick together.

[0030] Reference Figure 3, one end of the support frame 4 close to the feed inlet 101 is provided with a fixing block 16. A threaded hole is provided in the fixing block 16, and a bolt 17 is installed in the threaded hole. One end of the bolt 17 close to the conveyor belt 5 is connected with a scraper 18. Both ends of the scraper 18 are in contact with the support frame 4, and a scale is provided on the side wall of the support frame 4 close to the scraper 18. The scraper 18 is used to evenly spread the material on the conveyor belt 5, so as to avoid the material piling up together after the vibrating motor shakes the material apart, which affects the subsequent screening work of the color sorter body 1. By rotating the bolt 17, the distance between the bottom of the scraper 18 and the surface of the conveyor belt 5 can be adjusted to be equal to the maximum diameter screened by the previous process, and the above effect can be achieved. The scale line can assist in observing the adjustment and improve the working efficiency.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and obviously, many changes and variations are possible in light of the above teachings.
