Description

Technical Field

[0001] The invention belongs to the technical field of material transportation, and in particular relates to automatic material adding and subtracting equipment for a scraper loading mine vehicle. Background Art

[0002] In the process of mineral mining, the transportation of ore is mainly carried out by setting up rails between the outside world and the mine, and the mined ore is collected by scrapers. The collected ore will be collected in the material area by loading cars.

[0003] In recent years, to address national environmental protection initiatives and reduce dust pollution generated during cargo transportation, the traditional bulk cargo transportation method has been gradually shifting to containerized shipping, a process commonly known as "bulk to container." This shift not only effectively alleviates the environmental pressures associated with bulk cargo transportation but also improves cargo transportation safety and efficiency, reducing cargo loss during transportation. However, this shift also presents some new challenges, particularly regarding the accuracy of container packing weights. Ensuring the accurate weight of cargo in each container is crucial during container operations. Due to the wide variety and shape of cargo, as well as potential uneven distribution during loading, the actual weight of a container after weighing often differs from the specified standard.

[0004] The traditional solution to this problem is for loaders to manually adjust the weight of the cargo using simple tools like shovels. While this method can achieve a certain level of accuracy, it has significant drawbacks, including large errors, high labor intensity, low efficiency, and significant safety risks. Furthermore, during the transport process, the existing equipment can cause the loading truck to bump around due to uneven terrain, causing material to spill from the bucket. Therefore, our company has developed an automatic loading and unloading device for loading trucks on scrapers. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to provide an automatic material adding and subtracting device for a scraper loading mine car, so as to solve the disadvantages of manual adjustment mentioned in the background technology, such as large working errors, high labor intensity, low work efficiency, and high safety risks, as well as the problem that during the transportation process of the existing equipment, the loading mine car is easily bumped during movement due to the uneven site, causing the material to overflow from the bucket.

[0022] In one embodiment, Figures 1 to 3As shown, when the lifting part of the elevator 2 drops to the lowest point, the pull wire 8 is tightened, and the scraper 1 is used to shovel the mineral particles into the bucket 4. The electronic scale 5 observes the reading and feeds it back to the terminal control machine in the vehicle. The staff receives the final weight required by the driver, confirms the value, and operates the first telescopic rod 12 to push the push plate 10 to perform the material reduction operation. The lifting part of the elevator 2 rises, the pull wire 8 relaxes, and the folding iron plate 7 is opened and adsorbed to the front side of the bucket 4 by the strong magnet 9 to prevent leakage during transportation.

[0023] In one embodiment, Figure 2 、 Figure 3 and Figure 6 As shown, a platform 13 is provided on the limiting tube 11, a second telescopic rod 14 is horizontally provided on the platform 13, and a horizontal push plate 26 is provided at the front end of the second telescopic rod 14. When quantitative material extraction is required, the pull wire 8 is tightened when the lifting member of the elevator 2 drops to the lowest point, and the horizontal push plate 26 at the front end of the second telescopic rod 14 is pushed above the bucket 4. At this time, the bucket 4 is in a quantitative material extraction state, and the mineral particles are shoveled into the bucket 4 using the scraper 1. The electronic scale 5 observes the reading and feeds it back to the terminal control machine in the vehicle. The error does not exceed 5kg, and the lifting member of the elevator 2 rises, the pull wire 8 relaxes, and the folding iron plate 7 is opened and adsorbed to the front side of the bucket 4 by the strong magnet 9 to prevent leakage during transportation. However, there will be material on the horizontal push plate 26 in this state.

[0024] In one embodiment, Figures 1 to 7As shown, a carrier 13 is provided on the limiting tube 11, a second telescopic rod 14 is horizontally provided above the carrier 13, a movable push plate 15 is provided at the front end of the second telescopic rod 14, a rotating pin seat 16 is provided on the carrier 13, the tail of the second telescopic rod 14 is connected to the rotating pin seat 16 through a pin shaft, an arc-shaped through groove 17 is provided on the carrier 13, and the movable push plate 15 includes a sliding cover plate 19, a connecting plate 20, a connecting side hole plate 21 and an electromagnet suction block 22, one side of the connecting plate 20 is fixedly connected to the telescopic head of the second telescopic rod 14, and the connecting plate An electromagnet suction block 22 is provided on the other side of 20, and connecting side hole plates 21 are provided on the left and right sides of the connecting plate 20. A rotating shaft 23 is provided in the connecting side hole plate 21. The rotating shaft 23 is fixedly connected to the side of the sliding cover plate 19, and an anti-slip pattern is provided on one side of the sliding cover plate 19 close to the connecting plate 20. An anti-slip pattern is also provided in the arc-shaped through groove 17. The side of the sliding cover plate 19 close to the connecting plate 20 is an arc. The sliding cover plate 19 is composed of a hollow iron plate 24 and a solid iron plate 25. Another method of quantitative material removal is to remove the material in a quantitative manner. When quantitative material removal is required, the elevator 2 When the lifting part is lowered to the lowest point, the wire 8 is tightened, and the scraper 1 is used to shovel the mineral granular material into the bucket 4. The lifting part of the elevator 2 rises, the wire 8 is relaxed, and the folding iron plate 7 is opened and adsorbed to the front side of the bucket 4 through the strong magnet 9. At this time, there is a peak of granular material in the bucket 4. The solid iron plate 25 of the sliding cover plate 19 at the front end of the second telescopic rod 14 retracts and enters the arc groove 17. The sliding cover plate 19 is affected by the friction force in the arc groove 17 and gradually approaches the electromagnet suction block 22. The electromagnet suction block 22 is energized to slide the cover The plate 19 is sucked, and the second telescopic rod 14 pushes the vertical sliding cover plate 19 again at this time, which can flatten the material peaks of the granular material in the bucket 4 to prevent the material from spilling. After the work is completed, the second telescopic rod 14 pulls back the vertical sliding cover plate 19, and the vertical sliding cover plate 19 enters the arc-shaped through groove 17. The electromagnet suction block 22 loses power and the sliding cover plate 19 is disengaged. The second telescopic rod 14 pushes the horizontal sliding cover plate 19 to the top of the bucket 4 for sealing, thereby avoiding the accumulation of material on the sliding cover plate 19, which causes material leakage during transportation.
