Coal needs to be transported and stored after mining, and weighed during storage to calculate the quantity of coal. Most of them use large weighing devices for weighing, and vehicles loaded with coal need to be driven to the weighing device for weighing.

[0003] For example, application number: CN202220456328.4. The utility model relates to the technical field of coal mines and discloses an intelligent weighing device for coal mines, including a platform, triangular blocks are fixedly installed on the front and rear sides of the platform, slide grooves are opened on the left and right sides of the platform, connecting blocks are movably connected in the two slide grooves, and connecting strips are fixedly installed on the sides of the two connecting blocks away from each other, and the two connecting strips are respectively fitted with the left and right sides of the platform, and cleaning strips are fixedly installed on the two connecting strips.

[0025] As a technical optimization solution of the utility model, by setting a movable mechanism 9, when the cleaning strip 2 moves to the far left and the transport vehicle needs to be started to continue to move to the left and away from the top of the weighing platform 1, the electromagnet 93 is started first, so that the electromagnet 93 generates magnetic force and is magnetically adsorbed to the top of the weighing platform 1, so that the force-bearing seat 7 moves downward and stabilizes on the top of the weighing platform 1, so that the force-bearing seat 7 can be used, and at the same time, the sliding cooperation of the movable block 91 and the movable groove 92 is utilized to guide the force-bearing seat 7.

[0027] As a technical optimization scheme of the utility model, by providing the inlay groove 10 and the inlay strip 11, when the protective pad 8 is damaged after long-term use and needs to be replaced, the user can directly pull the protective pad 8 upward to separate the inlay strip 11 from the inlay groove 10, and then the user can inlay the inlay strip 11 into the inlay groove 10 on the new protective pad 8, thereby installing the new protective pad 8.

[0028] refer to Figure 2 The two sides of the top of the movable block 91 are fixedly connected with a limiting rod 12, the top of the limiting rod 12 passes through the top of the cleaning strip 2 and is slidably connected with the cleaning strip 2, and a tension spring 13 is sleeved on the surface of the limiting rod 12, one end of the tension spring 13 is fixedly connected to the two sides of the top of the inner wall of the movable groove 92, and the other end of the tension spring 13 is fixedly connected to the two sides of the top of the movable block 91.

[0029] As a technical optimization scheme of the utility model, by setting a limit rod 12 and a tension spring 13, when it is necessary to move the force-bearing seat 7 up and down, the sliding cooperation between the limit rod 12 and the cleaning strip 2 can be used to limit the force-bearing seat 7 front, back, left and right, thereby improving the movement stability. When the cleaning strip 2 is pushed by the transport vehicle to clean the debris on the top of the weighing platform 1, the user can turn off the electromagnet 93 so that the electromagnet 93 is no longer adsorbed on the top of the weighing platform 1, and then use the tension of the tension spring 13 to pull the movable block 91 upward, so that the movable block 91 drives the force-bearing seat 7 to move upward and lift it, thereby preventing the force-bearing seat 7 from affecting the cleaning of the cleaning strip 2.

By setting up a buckle groove, when the user needs to replace the protective pad 8, the user can apply force by buckling the buckle groove to drive the protective pad 8 to be pulled off.

[0036] The working principle and use process of the utility model are as follows: when the transport vehicle moves to the weighing platform 1 for weighing, the cleaning strip 2 will be pushed to move synchronously, and then the cleaning strip 2 will drive the scraping strip 3 to push and clean the debris on the weighing platform 1. When the cleaning strip 2 moves to the leftmost side and the transport vehicle needs to be started to continue to move to the left to leave the top of the weighing platform 1, the electromagnet 93 is first started to make the electromagnet 93 generate magnetic force and magnetically adsorb to the top of the weighing platform 1, so that the force-bearing seat 7 moves downward and stabilizes on the top of the weighing platform 1, so that the force-bearing seat 7 can be used, and at the same time, the sliding cooperation of the movable block 91 and the movable groove 92 can be used to guide the force-bearing seat 7, and then the right side of the force-bearing seat 7 is inclined, so that when the transport vehicle moves to the left, the wheels of the transport vehicle will move to the force-bearing seat 7 and pass over the cleaning strip. The sorting strip 2 moves to the left, thereby preventing the cleaning strip 2 from being squeezed and damaged. The protective pad 8 can be used to prevent the cleaning strip 2 from being rigidly squeezed when the speed of the transport vehicle is too low and the tire squeezes the cleaning strip 2, thereby improving the protection effect. When the force-bearing seat 7 needs to be moved up and down, the force-bearing seat 7 can be limited to the front, back, left and right by the sliding cooperation of the limit rod 12 and the cleaning strip 2, thereby improving the movement stability. When the cleaning strip 2 is pushed by the transport vehicle to clean the debris on the top of the weighing platform 1, the user can turn off the electromagnet 93 so that the electromagnet 93 is no longer adsorbed on the top of the weighing platform 1, and then use the tension of the tension spring 13 to pull the movable block 91 upward, so that the movable block 91 drives the force-bearing seat 7 to move upward and lift it, thereby preventing the force-bearing seat 7 from affecting the cleaning of the cleaning strip 2, and having the ability to assist in protecting the cleaning strip 2.

[0037] To sum up: the coal mine product weighing device, by setting a force-bearing seat 7, utilizes the inclined setting of the right side of the force-bearing seat 7, so that when the transport vehicle moves to the left, the wheels of the transport vehicle will move to the force-bearing seat 7 and cross the cleaning bar 2 to move to the left, and then use the protective pad 8 to avoid the cleaning bar 2 being rigidly squeezed when the speed of the transport vehicle is too low and the tire squeezes the cleaning bar 2, thereby improving the protection effect and solving the problem that when the transport vehicle drives the moving bar and the cleaning bar to the farthest distance, the transport vehicle will directly press over the cleaning bar and move outside the weighing platform, and the weight of the transport vehicle is relatively high, and the cleaning bar is easily damaged when it is squeezed by the transport vehicle, resulting in the cleaning bar being unable to continue to clean the top of the load-bearing platform in the subsequent process.
