[0024] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.
[0025] As shown in Figures 1-3 , a material leakage prevention device for a material guide trough of a scraper conveyor according to an embodiment of the present application comprises:
[0026] The scraper conveyor 1 is provided with a material guide trough 2 at the lower end thereof;
[0027] The expanded slot 3 is fixedly connected below the material guide trough 2;
[0028] The easily adjustable guide plate 4 is fixedly connected to the bottom end of the expanded slot 3 on both sides, and the belt conveyor 5 is arranged below the easily adjustable guide plate 4. Coal falls from the material guide trough 2 through the expanded slot 3 and the easily adjustable guide plate 4 and is guided to the belt conveyor 5, and then is transported to a downstream unit. During the falling process, the coal is always within the expanded slot 3 and the easily adjustable guide plate 4, and there is no obvious gap between the transport belt of the belt conveyor 5 and the material guide trough 2. The transport situation can be directly observed from the outer surface, so that it can be directly observed that no coal leakage occurs during the discharging process. In addition, the device can flexibly adjust the side height of the easily adjustable guide plate 4 according to different working conditions, so that there is always no obvious gap between the expanded slot 3 and the belt conveyor 5, thereby avoiding the problem of material scattering, and solving the problem of serious coal leakage between the belt gaps and serious safety hazards in personnel cleaning during the material transportation process in the prior art.
[0029] As shown in Figure 1 and 2As shown, the flared slot 3 is a trapezoidal flared slot, and the flared opening of the flared slot 3 is located at the lower side. The trapezoidal flared slot prevents the coal from piling up and blocking during the unloading process due to the slow transportation of the belt conveyor 5. The two sides of the end of the easy-to-adjust guide plate 4 along the coal transportation direction are fixedly connected with the trumpet mouth 6. The trumpet mouth 6 is cut from the waste belt. The trumpet mouth 6 limits the movement range of the coal on the belt conveyor 5, preventing the coal from falling and moving irregularly after being transported by the belt conveyor 5, which leads to the coal falling outside the guide range of the easy-to-adjust guide plate 4. The trumpet mouth 6 is attached to the belt conveyor 5. The trumpet mouth 6 cut from the waste belt is attached to the belt conveyor 5, so that the coal cannot fall out through the gap of the trumpet mouth 6. The trumpet mouth 6 and the easy-to-adjust guide plate 4 are fixedly connected with the inclined brace 7. The inclined brace 7 is used to strengthen the fixation of the trumpet mouth 6 to prevent the trumpet mouth 6 from deforming. The two sides of the easy-to-adjust guide plate 4 and the bottom end of the scraper 1 are fixedly connected with the connecting column 8. The connecting column 8 is used to connect and fix the easy-to-adjust guide plate 4. The two sides of the easy-to-adjust guide plate 4 and the bottom end of the scraper 1 are fixedly connected with the reinforcing rib 9. The reinforcing rib 9 further strengthens the support connection.
[0030] As shown in Figure 3 The easy-to-adjust guide plate 4 includes a guide plate body 41, a guide plate cover 42, and a sealing rubber strip 43. The guide plate body 41 is fixedly connected to the lower sides of the flared slot 3. The guide plate cover 42 is fixedly connected to the upper side of the guide plate body 41 and the unsealed top of the flared slot 3. The sealing rubber strip 43 is fixedly connected to the bottom end of the guide plate body 41 and contacts the conveying surface of the belt conveyor 5. The guide plate body 41 is used to guide the coal to be gradually transported by the belt conveyor 5. The sealing rubber strip 43 is in soft contact with the belt conveyor 5, thereby not causing wear to the belt conveyor 5.
[0031] As shown in Figure 3 The side surface of the sealing rubber strip 43 is provided with a plurality of fixing bolts 44. The sealing rubber strip 43 is connected to the guide plate body 41 through the fixing bolts 44. After long-term use, the sealing rubber strip 43 is worn out, and the sealing rubber strip 43 and the belt conveyor 5 have obvious gaps, which can easily cause coal to fall. When the sealing rubber strip 43 is severely worn, the fixing bolts 44 are used to remove and replace the sealing rubber strip 43, thereby resealing the gap and making replacement convenient and fast. The fixing bolts 44 are symmetrically arranged in multiple numbers, and the sealing rubber strip 43 is connected to the guide plate body 41 through the multiple fixing bolts 44. The multiple fixing bolts 44 prevent the sealing rubber strip 43 from falling off.
[0032] In conclusion, the working principle of the material leakage prevention device of the scraper guide chute according to the embodiments of the present application is as follows: coal falls from the guide chute 2 through the expansion slot 3 and the guide plate body 41 guided by the scraper 1 and then falls onto the belt conveyor 5, so as to be transported to a downstream unit; the coal is always in the expansion slot 3 and the easily-adjustable guide plate 4 during the falling process; there is no obvious gap between the transport belt of the belt conveyor 5 and the guide chute 2; the transport condition can be directly observed from the outer surface; the occurrence of coal leakage during the discharging process can be directly observed; and the device can adjust and replace the sealing rubber strip 43 through the fixing bolt 44 according to different working conditions, so that there is always no obvious gap between the expansion slot 3 and the belt conveyor 5, and the problem of material scattering is avoided, thereby solving the problem that coal is seriously scattered and leaked between the gaps of the belt during the material conveying process in the prior art, and the personnel cleaning has serious safety hazards.
[0033] The above merely illustrates the embodiments of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
