DETAILED DESCRIPTION

[0025] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[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. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0027] Example 1:

[0028] A crab claw type floating coal hopper, see attached Figure 1 and attached Figure 2As shown, the hopper comprises a hopper body 1 and shovel plates. The shovel plates include a left shovel plate 2 and a right shovel plate 3, each hinged to the side walls of the hopper body via a hinge shaft 4. The left and right shovel plates can each be tilted upward at a certain angle along the side walls of the hopper body. Specifically, a cover 5 is provided on the bottom surface of the shovel plate. A tilting cylinder 6 is hingedly mounted on the inner wall of the cover 5 via a cylinder seat. The telescopic end of the tilting cylinder 6 is hinged to the side wall of the hopper body 1 via the cylinder seat. The tilting cylinder 6 controls the left and right shovel plates 2 and 3 to tilt along the side walls of the hopper body 1 by telescoping.

[0029] Both the left shovel plate 2 and the right shovel plate 3 are provided with a coal collection 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 to the shovel plate via a hinge shaft, and the star wheel 9 rotates and fits on the shovel plate. The crab claw 8 is hinged to the star wheel 9 via a hinge 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. The mounting seat 10 is used to install a hydraulic motor (not shown in the figure), which is used to drive the star wheel 9 to rotate. The mounting seat 10 and the tilting cylinder 6 are both placed inside the cover 5, which can protect the hydraulic motor and the tilting 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 engaged with the hopper body. The driven shaft 13 is used to install the scraper chain. The rear end 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 robotic 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 is received 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). Operating the lifting cylinder 15 controls the up and down movement of the entire hopper. The tilting angles of the left and right shovel plates 2, 3, and the lifting height of the entire hopper can be adjusted based on the material accumulation and transportation requirements to ensure smooth entry of the material into the loading hopper. This also ensures that the pedestrian and rubber-wheeled vehicle passages on both sides of the roadway are clear. During the material collection process, the material falls onto the collection plate 12 of the hopper's collection channel 11. The material on the collection plate 12 is then transported to the subsequent crusher via a scraper chain that cooperates with the driven shaft 13 for crushing. The crushed material is then transported to a belt conveyor for output outside the roadway.

[0032] When it is necessary to process the floating coal in the tunnel, the mechanical arm of the tunneling equipment is used to operate the hopper to fit the hardened ground of the tunnel, and the turning cylinder 6 is operated to retract inwards, so that the left shovel plate 2 and the right shovel plate 3 are restored to the adjacent Figure 1 In the initial state shown, the excavation equipment shovels the floating coal on the ground into the hopper during its advancement. 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 along 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, greatly reducing the cleaning efficiency and cleaning cost of the floating coal. Through the above design, installing the hopper provided by the utility model on the excavation 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 roadway. This improves the excavation efficiency of the coal mine.

[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, thereby realizing that the crab claws 8 on the left shovel plate 2 and the right shovel plate 3 alternately send the floating coal at the hopper edge into the collection channel 11. Figure 5 As shown, a guide plate 16 is provided on the inner sidewall of the collection channel 11 to prevent the scraper chain from jumping. This prevents the scraper chain from jumping upward during material conveying, enhancing the conveying stability and preventing the material from falling due to shaking. Finally, an atomizing nozzle 17 is provided above the collection channel 11 to reduce dust during material conveying.

[0034] Example 2:

[0035] In this embodiment, in addition to the technical features of the above embodiment 1, please 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. 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. The telescopic end of the side thrust cylinder 19 is hinged to the expansion plate 18 through the cylinder seat. The cylinder body of the side thrust cylinder 19 is hinged to the outer wall of the cover shell 5 through the cylinder seat. During the cleaning process of 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 amount of floating coal fed into the hopper. Figure 2 As shown, after the diameter expansion plate 18 is rotated outward to its proper position, a limiting block 25 may be provided between the diameter expansion plate 18 and the shovel plate to prevent the diameter expansion plate 18 from rotating inward during operation.

[0036] Example 3:

[0037] In this embodiment, in addition to the technical features of the above-mentioned embodiment 1 and embodiment 2, a tensioning mechanism is provided on the driven shaft 13. Figure 7 As shown, the tensioning mechanism includes a tensioning cylinder 20 and a tensioning block 21. The tensioning block 21 slides against the sidewall of the collection channel 11. Specifically, a slot is provided along the length of the collection channel 11, and the tensioning block 21 slides within the slot. The driven shaft 13 is mounted on the tensioning block 21. A fixing plate 22 and a positioning plate 23 are fixedly mounted on the outer surface of the sidewall of the collection 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 connects to the tensioning block 21. A positioning clamp 24 is installed between the positioning plate 23 and the tensioning block 21. During material conveying, if the scraper chain becomes loose, the tensioning cylinder 20 can be controlled to extend outward, thereby moving the tensioning block 21 forward and driving the driven shaft 13 to tighten the loosened scraper chain. After the scraper chain is tightened, a positioning clip 24 is installed between the tensioning block 21 and the positioning plate 23. This allows the tensioning block 21 to abut against the positioning plate 23 via the positioning clip 24, keeping the scraper chain in a taut state. Furthermore, the positioning clip 24 includes multiple positioning clips of varying thicknesses. During operation, different thicknesses of positioning clips 24 can be selected to abut the tensioning block 21 based on the gap between the tensioning block 21 and the positioning plate 23. To prevent the positioning clip 24 from falling off, it can be fastened to the positioning plate 23 using fixing bolts.

[0038] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
