Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0032] Please refer to Figure 1-2 As shown in FIGS. and 4, the present invention is a kind of anti - splash protection mechanism for crushed stones used in mine excavation. The anti - splash protection mechanism includes a box body 10. Inside the box body 10, there are a support partition A 11 and a support partition B 12. On one side wall of the box body 10 above the support partition A 11, there is an opening A 113; and on the other side wall of the box body 10 between the support partition A 11 and the support partition B 12, there is an opening B 123, and the opening A 113 and the opening B 123 are respectively opened on the opposite side walls of the box body 10.

[0033] During use, insert the end of the first conveyor 100 into the box body 10 above the support partition A11 through the opening A113, and insert the first section of the second conveyor 200 into the box body 10 above the support partition B12 through the opening B123; rectangular holes A111 and B121 are respectively formed in the support partition A11 and the support partition B12; a conical blanking hopper A112 and a blanking hopper B122 are respectively connected at the rectangular holes A111 and B121. Then, during use, the ore conveyed on the first conveyor 100 falls onto the blanking hopper A112, and after the action of the blanking hopper A112, it falls onto the second conveyor 200. Furthermore, at this time, the ore continues to be conveyed under the action of the second conveyor 200.

[0034] During use, in order for the ore to fall onto the second conveyor 200 after the action of the blanking hopper A112 and then fall from the periphery of the second conveyor 200 onto the blanking hopper B122; in order to regularly clean up these scattered ores, a receiving box 15 is placed at the bottom of the box body 10, and the receiving box 15 is located directly below the blanking hopper B122; and the inner walls of the blanking hopper A112 and the blanking hopper B122 are laser-clad with tungsten carbide coatings.

[0035] In order to prevent the dust raised during the movement of the ore in the box body 10 from escaping into the air, in the present invention, a spray pipe 3 is connected between the two side walls of the box body 10 above the opening A113 and the opening B123; during use, an atomized water curtain is formed through the spray pipe 3, and the atomized water curtain is used to capture dust particles, thereby reducing the escape of the dust carried during the blanking process.

[0036] During use, in order to facilitate the control of the movement of the receiving box 15, one side of the box body 10 below the support partition B12 is open; rollers 154 are provided on the bottom surface of the receiving box 15, and a handle 151 is provided at one end of the receiving box 15; a channel 16 for cooperating with the rollers 154 is provided on the inner bottom surface of the box body 10. Furthermore, during use, the movement of the receiving box 15 in the inner bottom surface of the box body 10 can be controlled by controlling the movement of the receiving box 15 through the handle 151.

[0037] It can be known that in the above, such as Figure 3-4 , when the receiving box 15 is taken out of the box body 10, in order to prevent the ore from continuing to be discharged from the bottom outlet end of the blanking hopper B122, in the present invention, a U-shaped support beam 131 is connected to the inner wall of the box body 10 on both sides below the blanking hopper B122 through a connecting rod 13; it also includes a movable baffle 14 with both sides inserted into the two U-shaped support beams 131 respectively; a T-shaped pull rod 141 is provided at one end of the movable baffle 14, and a U-shaped limiting frame 142 is provided at the other end; that is, during use, before taking out from the receiving box 15, it is necessary to use the movable baffle 14 to block the bottom outlet end of the blanking hopper B122.

[0038] To ensure that when the receiving box 15 is located inside the box body 10, the closing of the movable baffle 14 is avoided, as Figure 5-7 , a lifting limit baffle 182 is provided on the box body 10, and the end of the limit baffle 182 extends between the U-shaped limit frame 142 and the movable baffle 14; a chamber 17 is formed inside the bottom of the box body 10, and a rectangular through hole 170 for the limit baffle 182 to penetrate is provided at the top of the chamber 17; the bottom end of the limit baffle 182 is connected to a base plate 181, and the base plate 181 is installed at the top end of a telescopic sleeve B18; the telescopic sleeve B18 is communicatively arranged with a telescopic sleeve A171 inside the chamber 17; a baffle 152 is further provided at the end of the receiving box 15 provided with a handle 151, and at least two ejector rods 153 are fixed to the inner wall of the baffle 152. The end of the telescopic sleeve A171 is connected to a vertical rod A172, and the end of the vertical rod A172 is connected to a cross rod A173; an opening 102 through which the ejector rod 153 passes is provided on one side of the chamber 17; thus, when a receiving box 15 is stored in the box body 10, at this time, after the ejector rod 153 passes through the opening 102, its end abuts against the end of the cross rod 173, driving the telescopic sleeve A171 to stretch. After the stretching is completed, at this time, under the communication effect, the telescopic sleeve B18 is controlled to contract, and the top of the limit baffle 182 is lower than the bottom of the U-shaped limit frame 142. At this time, the movable baffle 14 can be arbitrarily controlled to move along the length direction of the U-shaped support beam 131.

[0039] When it is necessary to block the bottom outlet end of the blanking hopper B122, the movable baffle 14 is controlled to move towards the inside of the box body 1 along the length direction of the U-shaped support beam 131. In the present invention, a mutually matching guiding inclined surface A and guiding inclined surface B are provided on the limit baffle 182 and the U-shaped limit frame 142, so as to control the movable baffle 14 to drive the limit baffle 182 to move downward under the action of the guiding inclined surface A and the guiding inclined surface B when moving. When the U-shaped limit frame 142 passes through the top of the limit baffle 182, at this time, the end of the limit baffle 182 extends between the U-shaped limit frame 142 and the movable baffle 14, and thus the outward pulling of the movable baffle 14 is restricted at this time.

[0040] In use, to facilitate the limiting of the receiving box 15, the present invention respectively sets side plates 143 at both ends of the end of the movable plug plate 14 close to the U-shaped limiting frame 142. A horizontally arranged telescopic sleeve C144 is provided on the inner wall of the box body 10; a telescopic sleeve D174 communicated with the telescopic sleeve C144 is provided on the inner top side of the chamber 17. The output end of the telescopic sleeve D174 is connected to a cross bar B175, and a vertical limiting rod 176 passing through the chamber 17 and extending to the outside is connected to the cross bar B175; a limiting boss 155 matching with the vertical limiting rod 176 is provided on the bottom side of the receiving box 15. Further, in use, when it is necessary to control the receiving box 15 to move into the box body 1 or move outward from the inside of the box body 1, at this time, it is necessary to control the telescopic sleeve D174 to extend. The extension of the telescopic sleeve D174 drives the vertical limiting rod 176 to move downward in the vertical direction, thereby releasing the limiting effect of the vertical limiting rod 176 on the receiving box 15.

[0041] Specifically, the telescopic sleeve A171, the telescopic sleeve B18, the telescopic sleeve C144 and the telescopic sleeve C144 have the same structure, and all include an inner sleeve and an outer sleeve that are hermetically fitted with each other, and a spring is connected between the inner sleeve and the outer sleeve.

[0042] Such as Figure 8 , a pipe body 19 with a gradually decreasing inner diameter from top to bottom is provided outside the bottom end of the blanking hopper A112. Connecting blocks 191 are respectively connected to both sides of the pipe body 19. A column 193 is fixed to the side wall of the box body 1 through a fixing block 194; the column 193 penetrates through the connecting block 191, and a locking screw 193 is provided on the connecting block 191; a scale mark is provided on the surface of the column 193, and the locking screw 193 is a butterfly screw with a lock washer.
