Description

Technical Field

[0001] The utility model relates to the technical field of quantitative coal loading equipment, in particular to a mobile material distributor for quantitative loading. Background Art

[0002] There are still few quantitative fast loading systems for bulk materials in China. On the one hand, there is no space reserved for installing quantitative weighing equipment during the early infrastructure construction process. On the other hand, there are many random factors in the automatic loading process of the car. It is not easy to load the car to the specified weight by manual judgment whether it is loaded in place, which can easily cause overloading or underloading. The previous manual loading method often requires unloading or adding materials, and the loading site is far away from the settlement and weighing place. If it cannot be loaded in place at one time, it is necessary to go back and queue up for loading again, which leads to increased transportation costs and waste of time.

[0003] There are 3 coal storage bunkers at the coal shipping site, with 2 types of coal, including 2 bunkers for clean coal and 1 bunker for mixed coal. The diameter of each bunker is 18 meters, and the daily shipping capacity is 5,000 tons. The feeding equipment under the bunker is a total of 18 reciprocating feeders and jaw loading gates. Two truck scales are installed outside the coal storage bunker for empty and heavy vehicle measurement.

[0004] At present, the coal is loaded and shipped by combining manual loading and forklift replenishment. The coal trucks are all under the charge of logistics companies. When loading coal with a loader, the two types of coal are directly placed into the car, which requires manual work to spread the coal, which is time-consuming, labor-intensive and labor-intensive. Moreover, the coal-loading center of gravity of the coal-loading vehicles is inconsistent, resulting in one side being full and the other side having a large surplus, which can easily lead to transportation safety hazards, increase the number of coal-leveling processes for drivers in the vehicle, cause vehicle detention in the factory, reduce the turnover rate within the factory, and bring safety hazards such as drivers working at high altitudes with cargo boxes. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a mobile material placing machine for quantitative loading to solve the technical problems existing in the prior art.

[0006] The technical solution adopted by the utility model is: a mobile material placing machine for quantitative loading, the mobile material placing machine is installed on a steel frame platform track, and the truck walking area is below the steel frame platform track.

Skirt belts are sleeved on the driving roller and the driven roller. Rollers are also installed on the frame between the driving roller and the driven roller.

[0007] Furthermore, two symmetrical coal levelers are installed on both sides of the truck walking area below the steel frame platform track.

[0008] Furthermore, each of the above-mentioned coal leveling machines includes a pressure plate, a hydraulic cylinder 1, a telescopic frame, a fixed frame and a hydraulic cylinder 2. The lower end of the pressure plate is hinged on the side of the L-shaped telescopic frame facing the truck walking area, and one end of multiple hydraulic cylinders 1 is hinged along the length direction near the middle of the outer side, and the other ends of the multiple hydraulic cylinders 1 are hinged on the outer frame of the telescopic frame.

The discharge ports of the two double-mouth hopper scales 3 are connected to the loading station 5 through a lifting belt conveyor 4. The loading station 5 is used for mixed coal loading; by controlling the weighing of the double-mouth hopper scale and then transporting it to the loading station by the lifting belt conveyor, mixed loading of different types of coal can be achieved, the loading efficiency is high, no manual assistance is required, the loading is automatically completed, the loading time is greatly shortened, no manual on-site cooperation is required, and the labor cost is reduced.

[0027] Among them, the loading station 5 includes two transfer belt conveyors 6 and a mobile material distributor 7. One end of the two transfer belt conveyors 6 is respectively connected to the tail ends of two side-by-side lifting belt conveyors 4. The relatively inner ends of the two transfer belt conveyors 6 are connected to the top of the mobile material distributor 7.

In order to facilitate pulling and pulling, multiple support pulleys 911 are arranged at the bottom of the two lateral slide grooves 910, and the support pulleys 911 support the sliding protrusions 909, which can reduce friction and make pushing and pulling easier.

[0029] The working principle of the coal leveling machine: After the vehicle cargo box is loaded with coal, control hydraulic cylinder 2 to push and pull it towards the cargo box, stop at the set position, and then pneumatic hydraulic cylinder 1 is used for compaction. During the compaction process, it returns to the original position for multiple times and performs compaction operations at different pulling and pulling positions. Both sides are carried out symmetrically and simultaneously, and the force is balanced.

[0030] In order to realize fast loading, the specific structure of the double-mouth hopper scale 3 includes a double-mouth hopper 301 and a pressure sensor 302. The double-mouth hopper 301 is connected to a bracket 303 through four pressure sensors 302 arranged at four symmetrical positions, and through four sides; a vibrator 304 is installed on the side wall of the double-mouth hopper 301 to facilitate the discharge of coal in the hopper and ensure the accuracy of the loading weight.

[0032] Embodiment 3: A method for using a mobile material placing machine for quantitative loading, the method comprising: (1) material preloading: sending a quantitative value to a double-mouth hopper scale, wherein the quantitative value of the double-mouth hopper scale of the clean coal bin is A tons, and the quantitative value of the double-mouth hopper scale of the mixed coal bin is B tons, and the total quantitative weight is A+B tons. The two double-mouth hopper scales are used to quantitatively weigh and control the feeding of two reciprocating coal feeders, and the reciprocating coal feeders are stopped when the set value is reached; (2) task confirmation: when a vehicle arrives at the loading station, the vehicle information is identified and read, and the vehicle information is obtained through card information docking, including coal type information, target load, empty vehicle weight, and vehicle size information. If the vehicle information is correct, the vehicle is allowed to enter for loading. If it is found to be an illegal vehicle, an alarm is issued to prohibit entry, and the loading data of the vehicle is retrieved and compared with the normal material. After confirmation, the remaining load (5 tons) is sent to the double-mouth hopper scale of the mixed coal bin. The hopper scale controls the feeding of two reciprocating coal feeders by quantitative weighing. When the set value is reached, the reciprocating coal feeder stops; (3) Vehicle positioning: The driver drives to the loading position for the first time according to the command system to check whether the vehicle is in place. During the driving process, the vehicle positioning system locates the vehicle position in real time. The large screen and voice interaction system prompt the driver in real time about the deviation from the target position to ensure that the driver can stop at the preset position at one time. If the vehicle is not in place, the voice screen prompts the driver to move the vehicle. After the vehicle is located, the system starts loading operations; (4) Automatic loading: The mobile spreader moves to the drop point at the rear of the carriage. The mobile spreader, loading belt conveyor, lifting belt conveyor, and fixed-value hopper scale flat discharge gate complete the loading operation; (5) Automatic coal leveling: When the vehicle arrives at the loading point, the coal leveler is started and pushed to the top of the car to start loading. After loading is completed, the coal leveler is used to compact the materials to complete the coal leveling operation. (6) End of loading: The end of loading is automatically controlled according to the target load. The vehicle is fully loaded on the large screen, and the voice broadcast announces the end of loading. The driver drives away from the channel, the system automatically saves the data, and the loading data is pushed to the transportation and sales system.
