Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a material weighing device used for filling and mining in coal mines. Background Art

[0002] In the process of backfill mining in coal mines, it is usually necessary to use filling materials such as sand, gravel or slag to fill the goaf to support the roof. During the filling process, in order to ensure the accuracy and effect of the filling, the staff usually use a material weighing device to accurately weigh the filled materials. The existing material weighing device usually consists of a scale body and a support block.

[0003] For example: The utility model with application number CN202120543614.X discloses a QR code intelligent access control and weighing equipment for coal mines, which specifically includes an access control device and a weighing device, characterized in that: the access control device includes a signal light, a QR code collection platform and a lifting gate, the signal light and the QR code collection platform are staggered on both sides of the road, the lifting gate is located directly behind the QR code collection platform, the weighing device includes a floor scale assembly and a support frame, the support frame is fixedly arranged on one side of the road and is located directly behind the floor scale assembly, the floor scale assembly includes a weighing plate, an infrared detector, a support column and a reinforcement groove, a protective pier is arranged between the lifting gate and the floor scale assembly, and a monitor and a camera are arranged on the support frame. The utility model has a high degree of intelligence, strong practicality of the device, and has a good development prospect.

[0004] However, with regard to the current traditional material weighing devices, the tires of vehicles transporting materials may carry dirt, stones and other debris. When the vehicle passes or stops on the floor scale, these debris will fall on the floor scale. At the same time, when the tires of the vehicle roll on the floor scale, they may roll up or raise dust on the ground, causing it to adhere to the floor scale, resulting in debris on the floor scale, affecting the weighing accuracy of the material weighing device, and making it inconvenient to use. Utility Model Content

[0005] The present invention provides a material weighing device for coal mine filling and excavation, which is provided with a cleaning scraper which can automatically clean up the debris on the main body of the scale when the vehicle passes by the main body of the scale. As the vehicle travels, the control push plate is pushed, so that the control push plate drives the auxiliary seat to move, and the movement of the auxiliary seat drives the guide slider to slide in the guide slide groove and squeeze the fixed spring. The setting of the limit block can ensure the stability of the control push plate during the pushing process. During the movement of the auxiliary seat, the cleaning scraper is driven to clean up the debris on the main body of the scale. As the guide slider moves, the fixed push rod pushes the control push rod to move, so that the control push rod drives the installation slide plate to slide along the control push rod and stretch the connecting spring. As the installation slide plate slides, the locking plug rod is driven to move, and as the locking plug rod moves, it is separated from the rotating shaft of the auxiliary seat. At this time, the continuous travel of the vehicle causes the auxiliary seat to rotate and screw the auxiliary torsion spring, so that the control push plate is flipped so that the vehicle can drive out smoothly.

[0006] The utility model provides a material weighing device for coal mine filling and mining, specifically comprising: a floor scale body; two support blocks are symmetrically fixedly connected to the outer side of the floor scale body; the two support blocks are both wedge-shaped block structures; two guide slide grooves are symmetrically provided on the outside of the floor scale body; a guide slider is slidably connected in the two guide slide grooves; the positions of the two guide sliders are aligned; an auxiliary seat is rotatably connected in the two guide sliders; a group of connecting plates are fixedly connected to the outsides of the two support blocks; a collection box is arranged between the two groups of connecting plates; the positions of the two collection boxes are aligned; the two collection boxes are aligned with the positions of the floor scale body.

Beneficial Effects

[0012] The utility model can push the control push plate to move along the main body of the scale when the vehicle loaded with materials drives onto the main body of the scale, and the debris on the main body of the scale can be cleaned up during the movement of the control push plate. The material dividing trough is provided so that the debris can be dispersed to both sides of the main body of the scale and fall into the collection box for collection. When the control push plate moves to the rear of the main body of the scale, the fixed push rod pushes the control push rod to move, and then the limit of the auxiliary seat is released through a series of transmissions. At this time, the driving of the vehicle will push the control push plate to flip, which is convenient for the vehicle to drive out of the main body of the scale. The operation is simple and quick, which effectively improves the convenience of the material weighing device and is more convenient to use.

[0013] The collection box is fixed by the cooperation of the locking plug and the locking slot. When the debris collected in the collection box needs to be cleaned, the staff only needs to press down the locking plug to disengage it from the locking slot. At this time, the staff can remove the collection box to clean the collected debris, which ensures the collection effect of the collection box on the debris and makes it convenient for the staff to clean the collected debris, further improving the convenience of the material weighing device.
