[0026] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0027] Embodiment 1:

[0028] A crab claw type floating coal hopper, see attached Figure 1 and attached Figure 2 As shown, it includes a hopper body 1 and a shovel plate, wherein the shovel plate includes a left shovel plate 2 and a right shovel plate 3 respectively hinged on the two side walls of the hopper body through a hinge shaft 4, and the left shovel plate and the right shovel plate can be respectively flipped upward at a certain angle along the side wall of the hopper body. Specifically, a cover 5 is provided on the bottom surface of the shovel plate, and a flip cylinder 6 is hingedly installed on the inner wall of the cover 5 through a cylinder seat, and the telescopic end of the flip cylinder 6 is hinged on the side wall of the hopper body 1 through the cylinder seat, and the flip cylinder 6 controls the left shovel plate 2 and the right shovel plate 3 to flip along the side wall of the hopper body 1 by telescoping.

[0029] The left shovel plate 2 and the right shovel plate 3 are both provided with a coal collecting mechanism, which includes a claw arm 7, a crab claw 8 and a star wheel 9. One end of the claw arm 7 is hinged on the shovel plate through a dumpling shaft, and the star wheel 9 is rotatably fitted on the shovel plate. The crab claw 8 is hinged on the star wheel 9 through a dumpling shaft, and the other end of the claw arm 7 is hinged to the crab claw 8. A mounting seat 10 is fixedly provided on the bottom surface of the shovel plate, and the mounting seat 10 is used to install a hydraulic motor (not shown in the figure), and the hydraulic motor is used to drive the star wheel 9 to rotate. The mounting seat 10 and the flip cylinder 6 are both placed inside the cover 5, and the cover 5 can protect the hydraulic motor and the flip cylinder 6.

[0030] The hopper body 1 is provided with a collecting channel 11, and a collecting plate 12 is installed in the collecting channel 11. Figure 3 and attached Figure 1 As shown, the front end of the collecting plate 12 is provided with a driven shaft 13 that is rotatably matched with the hopper body, and the driven shaft 13 is used to install the scraper chain. The tail of the hopper body 1 is provided with a mounting head 14 and a lifting cylinder 15 for mounting the hopper body 1 on a mechanical arm.

[0031] In the specific use process of the present invention, the present invention is installed on the mechanical arm of the excavation equipment such as the anchor transporter and the transfer machine through the installation head 14 and the lifting cylinder 15. The scraper chain of the transfer equipment is installed on the driven shaft 13. When the material receiving operation is performed during the excavation process, the turning cylinder 6 is operated to extend outward, and the left shovel plate 2 and the right shovel plate 3 are turned upward along the side of the hopper body 1 under the action of the turning cylinder 6 (as shown in the attached figure). Figure 4 As shown). Operate the lifting cylinder 15 to control the up and down movement of the entire hopper. The flipping angle of the left shovel plate 2 and the right shovel plate 3 and the lifting height of the entire hopper can be adjusted according to the material accumulation and transportation requirements to ensure that the material can smoothly enter the loading hopper. At the same time, it can also ensure that the pedestrian passages and rubber-wheeled vehicle passages on both sides of the lane are cleared. During the material receiving process, the material falls onto the collecting plate 12 of the collecting channel 11 of the hopper. The material on the collecting plate 12 is transported to the subsequent crusher for crushing through the scraper chain matched with the driven shaft 13. The crushed material is transported to the belt conveyor and output to the outside of the lane.

[0032] When it is necessary to process the floating coal in the tunnel, the mechanical arm of the tunneling equipment operates the hopper to fit the hardened ground of the tunnel, and operates the flip cylinder 6 to retract inward, so that the left shovel plate 2 and the right shovel plate 3 are restored to the adjacent Figure 1In the initial state shown, the floating coal on the ground is shoveled into the hopper during the advancement of the tunneling equipment. At the same time, the hydraulic motors on the left shovel plate 2 and the right shovel plate 3 are started, and the hydraulic motors drive the star wheel 9 to rotate. During the rotation of the star wheel, the crab claw 8 is driven to continuously send the floating coal at the edge of the hopper into the collecting plate 12 of the collecting channel 11 of the hopper body 1, thereby realizing the collection of the floating coal, which greatly reduces the cleaning efficiency and cleaning cost of the floating coal. Through the above design, installing the hopper provided by the present invention on the tunneling equipment can make the equipment not only have the function of receiving and transporting materials, but also use the equipment to collect and load the floating coal in the tunnel. The tunneling efficiency of the coal mine is improved.

[0033] It should be noted that the star wheel on the left shovel plate 2 and the star wheel on the right shovel plate 3 rotate in opposite directions, so that the crab claws 8 on the left shovel plate 2 and the right shovel plate 3 can alternately deliver the floating coal at the edge of the hopper into the collection channel 11. Figure 5 As shown, a guide plate 16 for preventing the scraper chain from jumping is arranged on the inner wall of the collection channel 11. The guide plate 16 can prevent the scraper chain from jumping upward during the material conveying process, enhance the stability during the conveying process, and prevent the material from falling due to shaking. Finally, an atomizing nozzle 17 is arranged above the collection channel 11 to reduce dust during the material conveying process.

[0034] Embodiment 2:

[0035] In this embodiment, in addition to the technical features of the above embodiment 1, continue to refer to the attached Figure 2 As shown, an expansion plate 18 hinged to the shovel plate is provided on the side wall at the front end of the shovel plate, and the expansion plate 18 can rotate outward along the hinge point with the shovel plate to increase the feed diameter of the shovel plate. Specifically, a side thrust cylinder 19 is provided on the bottom surface of the shovel plate, and the telescopic end of the side thrust cylinder 19 is hinged to the expansion plate 18 through the cylinder seat, and the cylinder body of the side thrust cylinder 19 is hinged to the outer wall of the cover shell 5 through the cylinder seat. In the process of cleaning floating coal, the side thrust cylinder 19 can be controlled to extend outward, thereby causing the expansion plate 18 to rotate outward along the hinge point with the shovel plate, thereby increasing the feed diameter of the shovel plate (as shown in the attached figure). Figure 6 As shown in the figure, increase the floating coal feed rate in the hopper. Figure 2 As shown, after the diameter expansion plate 18 is rotated outward to the right position, a limit block 25 can be set between the diameter expansion plate 18 and the shovel plate to prevent the diameter expansion plate 18 from rotating inward during operation.

[0036] Embodiment 3:

[0037] In this embodiment, in addition to the technical features of the above-mentioned embodiment 1 and embodiment 2, a tensioning structure is provided on the driven shaft 13. Figure 7As shown, the tensioning mechanism includes a tensioning cylinder 20 and a tensioning block 21. The tensioning block 21 is slidably fitted on the side wall of the collecting channel 11. Specifically, a slot is provided in the collecting channel 11 along the length direction of the collecting channel 11, and the tensioning block 21 is slidably fitted in the slot. The driven shaft 13 is mounted on the tensioning block 21. A fixing plate 22 and a positioning plate 23 are fixedly provided on the outer surface of the side wall of the collecting channel 11. The cylinder body of the tensioning cylinder 20 is fixedly mounted on the fixing plate 22. The telescopic end of the tensioning cylinder 20 passes through the positioning plate 23 and is connected to the tensioning block 21. A positioning card plate 24 is installed between the positioning plate 23 and the tensioning block 21. When conveying materials, if the scraper chain is loose, the tensioning cylinder 20 can be controlled to extend outward, so that the tensioning block 21 moves forward and drives the driven shaft 13 to tighten the loose scraper chain. After the scraper chain is tightened, a positioning card plate 24 is added to the tension block 21 and the positioning plate 23, so that the tension block 21 is abutted against the positioning plate 23 through the positioning card plate 24, and the scraper chain is kept in a tightened state. Furthermore, the positioning card plate 24 includes multiple positioning card plates of different thicknesses. In the implementation process, positioning card plates 24 of different thicknesses can be selected according to the gap between the tension block 21 and the positioning plate 23 to tighten the tension block 21. To prevent the positioning card plate 24 from falling off, the positioning card plate 24 can be fastened to the positioning plate 23 by fixing bolts.
