Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation, in particular to a cargo volume metering device for intelligent loading of coal mines. Background Art

[0002] A coal mine refers to a place rich in coal resources. When the coal seam is far away from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to mine coal. This is an open-pit coal mine. After excavation, the coal needs to be loaded and transported, and metering equipment is required when loading.

[0003] Through research and analysis, it is found that although coal mines can be measured, the following shortcomings still exist to a certain extent.

[0004] For example, because it does not have the function of accurate measurement during use, it is easy to cause the weight of coal loaded on each vehicle to be inconsistent during loading, which is inconvenient for subsequent statistics of coal and reduces the accuracy of measurement. It also does not have the function of cleaning. Therefore, when transporting coal, coal slag is easy to stick to the conveyor belt, making the surface of the conveyor belt dirty and causing waste of coal. In order to solve the above technical problems, we have designed a coal mine intelligent loading cargo metering equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a coal mine intelligent loading cargo metering device, which has the advantages of accurate metering and cleaning, and solves the problems of lack of accurate metering and lack of cleaning.

[0011] Preferably, the surface of the conveying roller is drivingly connected to a conveying belt, and the surface of the conveying belt is fixedly connected to a baffle.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the advantage of accurate measurement through the coordination of an alarm, a storage barrel, a weighing plate, a first motor, a connecting frame, a feeding auger, a weight sensor and a floor scale. When measuring, the coal is first injected into the storage barrel, and the coal injected into the storage barrel is weighed by the weight sensor. When the weight is reached, the alarm sounds, the transportation of the coal is stopped, and the truck is driven onto the floor scale. The operation of the first motor drives the feeding auger to rotate, and the feeding auger can be used to quantitatively inject coal into the truck. At the same time, the truck is further weighed by the floor scale, thereby improving the measurement accuracy.

[0014] 2. The utility model has the advantage of cleaning by cooperating with a cleaning brush, a belt pulley, a belt, a guide plate, a second motor and a conveying roller. When the second motor drives the upper conveying roller and the belt pulley thereon to rotate, the belt rotation drives another belt pulley to rotate, thereby allowing the cleaning brush to rotate, thereby cleaning the surface of the conveyor belt, and the cleaned coal slag falls into the storage barrel through the guide plate, thereby making the surface of the conveyor belt cleaner and reducing coal waste.

[0023] See also Figure 1 and Figure 3 The cleaning assembly 9 includes a cleaning brush 901, and the front and rear ends of the cleaning brush 901 are movably connected to the surface of the mounting plate 8 through bearings. The rear ends of the cleaning brush 901 and the upper conveying roller 704 are both penetrated to the back of the rear mounting plate 8 and fixedly sleeved with a belt pulley 902. The surface of the belt pulley 902 is connected with a belt 903 for transmission. The bottom of the mounting plate 8 is connected to a guide plate 904 by bolts. By setting the guide plate 904, the coal slag swept down by the cleaning brush 901 can be diverted so that the coal slag can fall into the storage barrel 5;
