[0019] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0020] As shown in Figures 1-4 An embodiment of the present application provides an ore cleaning and conveying device, which comprises two dust removal boxes 1, each of which is fixed at the two sides of the lower end of an upper conveying belt 2, an inclined guide chute 3 is fixed between the two dust removal boxes 1, the upper end of the guide chute 3 is connected with the upper conveying belt 2, and the lower end of the guide chute 3 is connected with a lower conveying belt 4, the opposite side of each of the two dust removal boxes 1 is provided with a dust suction net 6, the side end of the dust removal box 1 is communicated with a negative pressure device through a vacuum pipe 7, a filter plate 8 is vertically fixed between the dust suction net 6 and the vacuum pipe 7 in the dust removal box 1, and a dust collecting box 9 capable of being pulled out is arranged at the lower end of the filter plate 8 in the dust removal box 1.

[0021] During installation, the two dust removal boxes 1 are fixed at the two sides of the lower end of the upper conveying belt 2, so that the dust suction nets 6 on the two dust removal boxes 1 clamp the lower end of the upper conveying belt 2. The guide chute 3 is fixed between the two dust removal boxes 1 in an inclined manner, and is used for connecting the upper conveying belt 2 and the lower conveying belt 4 to guide the falling material. During use, the vacuum pipe 7 is communicated with the negative pressure device, the negative pressure device is a negative pressure fan or a vacuum pump, and when the ore material conveyed by the upper conveying belt 2 is transferred to the lower conveying belt 4, the ore material is guided to slide along the inclined surface of the guide chute 3 to the lower conveying belt 4. The dust generated in the falling process of the ore material is sucked into the dust removal box 1 through the negative pressure from the dust suction net 6, and the dust is filtered through the filter plate 8 in the dust removal box 1 and then falls into the dust collecting box 9. The dust collecting box 9 can be pulled out of the dust removal box 1 to clean and collect the dust.

[0022] In the embodiment, the two dust removal boxes 1 are clamped and fixed at the two sides of the upper conveying belt 2, which is convenient for installation and modification of the existing equipment, and the appropriate guide chute 3 is arranged according to the distance required to connect the upper conveying belt 2 and the lower conveying belt 4. The ore material is guided to slide along the inclined surface through the guide chute 3, which can reduce the falling difference and reduce the dust generated in the falling process of the ore material, and also can reduce the impact of the ore material on the lower conveying belt 4 when the ore material falls. The dust generated along the path in the falling process of the ore material is sucked into the dust removal box 1 through the negative pressure from the dust suction nets 6 at the two sides to be collected and stored, and the dust suction effect is better along the path where the dust is generated from the two sides, and the dust is regularly cleaned through the dust collecting box 9.

[0023] As shown in Figure 5 and Figure 6As shown in a possible implementation, the guide chute 3 is formed into a lining through the upper and lower through holes 10, and a receiving box 5 is arranged below the guide chute 3 and fixed between the two dust removal boxes 1.

[0024] The guide chute 3 is formed into a lining through the through holes 10, which can enhance the wear resistance. The first falling ore is clamped in the through holes 10 when falling into the guide chute 3, and the subsequent falling ore slides through the clamped ore, and the clamped ore in the through holes 10 is in contact with the falling ore, which reduces the wear of the guide chute 3 by the ore and improves the service life of the guide chute 3. The clamped ore in the through holes 10 falls into the receiving box 5 from the lower end after being worn, and the new ore is clamped in the through holes 10 to play the role of the lining.

[0025] As shown in Figure 1 and Figure 5 As shown in a possible implementation, the guide chute 3 is fixed through two support rods 12 below, and the guide chute 3 is hinged with one of the support rods 12, and the two ends of the support rod 12 are respectively inserted into the vertical sliding grooves 11 of the dust removal boxes 1 and connected in sliding mode, and the support rod 12 can be fixed in the sliding grooves 11 through bolts.

[0026] The two support rods 12 can move up and down along the sliding grooves 11 to adjust the height of the guide chute 3, and one of the support rods 12 can move up and down along the sliding grooves 11 to adjust the slope of the guide chute 3. After adjustment, the support rod 12 is locked and fixed with the sliding groove 11 through the bolts at the ends.

[0027] In a possible implementation, the upward end of the guide chute 3 is fixed with a curtain 13 arranged between the two dust removal boxes 1.

[0028] The curtain 13 is used to shield the open end below the guide chute 3, so as to reduce the dust overflow caused by the falling of the worn ore from the lower end.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
