DETAILED DESCRIPTION

[0031] The principles and spirits of the utility model are explained in detail below by referring to several representative embodiments of the utility model.

[0032] Please refer to Figures 1-7 , the utility model is described in detail below by combining with the drawings and examples:

[0033] For example Figures 1-3As shown, a kind of open-pit mine sealing conveying device, including support platform 1 and conveyor belt 2, the both ends of support platform 1 are symmetrically rotatably installed with roller 21, conveyor belt 2 is connected with two rollers 21 and is made sliding fit, and conveyor belt 2 is slid on the surface of support platform 1, support platform 1 is used to support conveyor belt 2, improves the conveying effect of ore, and the surface of conveyor belt 2 is symmetrically provided with baffle 11, the shape of baffle 11 corresponds to the conveying shape of conveyor belt 2, does not affect the normal movement of conveyor belt 2, and connecting frame 12 is fixed on the outer side of baffle 11 and the upper surface of support platform 1, to support baffle 11.

[0034] Specifically, the baffle 11 is used to concentrate the ore transported by the conveyor belt 2, to prevent the ore from spreading to both sides and falling off during transportation.

[0035] As Figure 1 shown, support platform 1 has two layers of plates, and a plurality of X-shaped support frames 13 for enhancing support effect are fixedly connected between the two plates.

[0036] As Figure 1 shown, a feeding frame 6 is provided above the ore feeding position of the conveyor belt 2, a dust suction frame one 4 is provided on the left side of the feeding frame 6, and dust suction frame twos 5 are symmetrically provided on both sides of the dust suction frame one 4. The feeding frame 6, the dust suction frame twos 5 and the dust suction frame one 4 are all fixedly provided on the side surfaces of the two side baffles 11 by bolts.

[0037] Specifically, the pipe positions of the dust suction frame one 4 and the dust suction frame twos 5 are all connected to the air suction mechanism of the external environment, and the air suction mechanism is used to effectively extract and process the dust generated during transportation. The above-mentioned air suction mechanism is a prior art and is not described here.

[0038] As Figures 1-5 shown, ore placing assembly 3 is provided between the two baffles 11, and the ore placing assembly 3 is installed along the surface of the conveyor belt 2. The ore placing assembly 3 includes placing frame 31 and rubber connecting pipe 32. The placing frame 31 is made of hard material and can bear the ore. The two mounting bars at the lower end of the placing frame 31 are fixedly connected to the conveyor belt 2 by bolts, facilitating replacement of the placing frame 31. The upper end of the placing frame 31 is provided in a trapezoidal groove. In order to better hold the ore, a plurality of through holes 311 are formed in the two inclined surfaces and the horizontal surface of the trapezoidal groove above the placing frame 31, facilitating separation of the powder in the transported ore from the ore body and reducing dust splashing during transportation.

[0039] Specifically, when the ore is placed into the placing frame 31, a part of the dust will enter the surface of the conveyor belt 2 through the through holes 311, and the subsequent dust can be effectively extracted by the two dust suction frame twos 5.

[0040] AsFigures 3-5 As shown, the rubber connecting pipe 32 connects two adjacent placing racks 31 by bonding, fills the gap between the upper ends of two adjacent placing racks 31, avoids large particles of ore from being stuck between two placing racks 31, and then deforms along with the movement of the conveying belt 2 at the bending position of the conveying belt 2. Since the rubber connecting pipe 32 has great elasticity, the two connecting positions of the placing racks 31 at the bending position can be effectively connected, and the normal transportation of the conveying belt 2 is not affected.

[0041] As shown in the Figure 2 As shown, the filter plate 51 is fixedly installed at the dust suction port position of the dust suction frame two 5, and can prevent the ore on the placing frame from being sucked into the dust suction frame two 5.

[0042] As shown in the Figure 6 As shown, the discharging rod 61 is fixedly installed on the inner wall of the feeding frame 6, and can divide the discharged ore, slow down the impact of the ore on the placing rack 31 during discharging, and prolong the service life of the placing rack 31. In addition, the feeding frame 6 can also limit the stacking height of the conveyed ore. When the ore stack after the feeding frame 6 enters between the dust suction frame one 4 and the dust suction frame two 5, the height of the ore stack will be reduced, facilitating the extraction of dust in the ore stack.

[0043] Specifically, after the ore enters the placing rack 31 through the feeding frame 6, the ore is conveyed by the movement of the conveying belt 2, and then the dust is extracted when passing through the dust suction frame one 4 and the dust suction frame two 5. During the extraction process, the ore on the placing frame 31 is sucked by the two dust suction frames two 5 through the through hole 311, and the dust flying is sucked by the dust suction frame one 4 above. The cooperation of the dust suction frame one 4 and the dust suction frame two 5 can effectively reduce the flying phenomenon of the dust during the transportation of the ore.

[0044] As shown in the Figures 1-7 As shown, the support plates 14 are symmetrically fixed at the middle positions of the two layers of plate members of the support table 1, the rotating shafts 232 are rotatably arranged between the two support plates 14, the pulley two 231 is fixedly installed on the outer surface of the rotating shaft 232 beyond the support plate 14, the pulley one 22 is fixedly installed on the outer surface of the roller 21, and the transmission belt 23 is connected between the pulley one 22 and the pulley two 231.

[0045] The driving unit is connected to the outer end of the roller 21, which can provide rotating force to the roller 21, and can be installed on the vertical rod side of the support table 1. The driving unit is a prior art, which is not drawn and described here.

[0046] The driving unit drives the roller 21 to rotate, and then drives the conveying belt 2 to move, and the pulley one 22 and the transmission belt 23 drive the pulley two 231 and the rotating shaft 232 to rotate.

[0047] As shown in the drawings, the rotating shaft 232 is fixedly arranged on the surface of the rotating shaft 232, and the support strip 233 is slidably arranged on the surface of the support strip 233. Figure 7 The support strip 233 is fixedly connected with the striking frame 234 between the striking frame 234 and the support strip 233, and a plurality of springs 235 are arranged on the surface of the striking frame 234.

[0048] As shown in the drawings, the rotating shaft 232 is fixedly arranged on the surface of the rotating shaft 232, and the support strip 233 is slidably arranged on the surface of the support strip 233.
