[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0031] like Figure 1~Figure 2 As shown, the utility model is a mine material dropping automatic wind shielding ore discharge device, comprising a hopper 1, a hinge assembly 2, a counterweight block 3, a balance rod 4, a limit beam 5, and a wind shielding door plate 6;
[0032] Among them, two wind shield plates 6 cover the bottom of the discharge port of the hopper 1 and are symmetrically arranged, and are hinged on both sides of the bottom of the hopper 1 respectively. The wind shield plate 6 is a rectangular plate, made of steel plate with a thickness of not less than 6 mm, and a rib plate can be welded on the bottom surface to resist the impact deformation of the block material.
[0033] The hinge assembly 2 includes a bearing seat, a rotating shaft, and an axle seat; the bearing seat is fixed to both sides of the bottom of the hopper 1 with anti-loosening bolts, and two bearing seats are fixed on each side, and bearings are installed in the bearing seats; the two axle seats on each side are welded to the outer end of the windshield door plate 6; the rotating shaft passes through the axle seat and the bearings in the bearing seat; the rotating shaft is fixed to the axle seat with bolts and flat keys, and the windshield door plate 6 can rotate freely around the bearing seat through the rotating shaft.
[0034] The balance bar 4 is welded to the outer end of the windshield door plate 6. The balance bar 4 is composed of a cantilever bar and a cross tube welded together. The counterweight 3 is fixed to the cross tube of the balance bar 4 with bolts.
[0035] The limit beam 5 is fixedly connected to the frame of the belt conveyor 7 by bolts. A plurality of mounting holes are arranged on the frame. The limit beam can be installed in different hole positions as required to limit and adjust the maximum opening angle of the windshield door plate 6.
[0036] The blocking part of the limiting beam 5 is installed with a rubber block. When the upper hopper suddenly discharges a large amount of material, it will impact the windshield door plate 6 to open quickly. The rubber block is used to buffer the impact force when the windshield door plate 6 is opened to prevent the device from being damaged by impact.
[0037] The detection port of the angular displacement sensor is elastically connected to the end of the rotating shaft of the hinge assembly 2. The angular displacement sensor is fixed to the side wall of the hopper 1 with bolts, one on each side, and the output cable is connected to the control room.
[0038] The polymer material plate laid on the windshield door plate 6 is selected from impact-resistant polymer materials on the market, has a thickness of not less than 8mm, has the same overall dimensions as the windshield door plate 6, and is fixed to the windshield door plate 6 with countersunk bolts.
[0039] A sealing skirt is hung around the hopper 1, and the lower end of the sealing skirt is crimped to the sealing cover of the belt conveyor 7 with bolts to prevent dust from flying due to falling materials from a high place.
[0040] The working principle and use method of the utility model are as follows: when the hopper 1 is empty, the windshield door plate 6 is pressed on the bottom discharge port of the hopper 1 under the gravity of the counterweight block 3 and the lever action of the balance rod 4, thereby closing the bottom discharge port of the hopper 1 and blocking the air leakage channel. When the upper ore 8 enters the hopper 1 and falls downward, the windshield door plate 6 is pushed to rotate outward around the rotating shaft of the hinge assembly 2 under the action of the gravity and impact force of the ore 8, and the windshield door plate 6 opens, and the ore 8 falls onto the belt conveyor 7 for transportation, and the switch state of the windshield door plate 6 is transmitted to the control room in real time by the angular displacement sensor. The utility model mine material dropping automatic windshield ore discharge device realizes the functions of automatic switch, air leakage prevention, unmanned operation, remote monitoring, no power consumption, green environmental protection, and simple structure. It is not only suitable for underground ventilation operations in coal mines, but also suitable for various mines with ventilation requirements, and has promotion value.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
