Description

Technical Field

[0001] The present invention relates to the technical field of mining machines, and in particular to a material collecting and transporting device and a mining machine. Background Art

[0002] In the related art, a star wheel device is installed on the shovel part of the open-pit miner, and the star wheel claw rotates to actively collect materials. In this design, the structure of the shovel part is complex, prone to failure, and has low material collection efficiency. Summary of the invention

[0003] In order to solve or improve at least one of the above technical problems, an object of the present invention is to provide a material collecting and transporting device.

[0004] Another object of the present invention is to provide a mining machine having the above-mentioned material collecting and transporting device.

[0005] To achieve the above-mentioned object, a first aspect of the present invention provides a material collecting and transporting device, comprising a frame, a shovel plate, a belt conveyor and a milling drum.

[0006] The shovel plate part includes a receiving hopper which is movably arranged on the frame. The receiving hopper has a first limit position and a second limit position. The receiving hopper can move relative to the frame from the first limit position to the second limit position, or from the second limit position to the first limit position.

[0007] One end of the belt conveyor is connected to the shovel plate part, and the belt conveyor is connected to the frame through a first hanging assembly. The milling drum is rotatably arranged on the frame.

[0008] In the process that the receiving hopper moves from the second extreme position to the first extreme position, the receiving hopper gradually approaches the milling drum. When the receiving hopper is in the first extreme position, the milling drum is used to throw materials into the receiving hopper.

[0009] In the technical solution of the present invention, firstly, by setting a milling drum at the front end of the receiving hopper of the shovel plate part, under the material collecting condition, the milling drum can throw the material into the receiving hopper, and the shovel plate part does not need to be provided with a star wheel device, and only plays the role of passive material collecting. This design method is conducive to simplifying the structure of the shovel plate part, reducing the maintenance cost and failure risk caused by the star wheel device, and the material collecting efficiency is higher; secondly, the collected materials are directly transported out through the belt conveyor, and there is no need to set a scraper conveyor between the shovel plate part and the belt conveyor, which is conducive to reducing energy consumption, reducing the wear between the material and the transportation device (belt conveyor), and can also reduce the risk of failure points; thirdly, the receiving hopper of the shovel plate part can move relative to the frame between the first limit position and the second limit position, and the position of the receiving hopper can be adjusted according to actual needs (under the material collecting condition, the receiving hopper is in the first limit position; under the walking condition, the receiving hopper is in the second limit position), which is conducive to improving the flexibility of the shovel plate part; fourthly, the receiving hopper and the belt conveyor move with each other to ensure continuous transportation of materials without leakage.

[0010] In addition, the above technical solution provided by the present invention may also have the following additional technical features:

[0011] In some technical solutions, the material collection and transportation device may further include a guide and limit device. The guide and limit device is disposed on the frame. When the receiving hopper moves from the first limit position to the second limit position, or from the second limit position to the first limit position, the guide and limit device is used to guide and limit the receiving hopper.

[0012] In this technical solution, when the receiving hopper moves relative to the frame between the first limit position and the second limit position, the receiving hopper can be offset against the guide limit device. By setting the guide limit device, the receiving hopper can be guided and limited, ensuring the stability of the movement of the receiving hopper relative to the frame, and effectively preventing the receiving hopper from deviating from the preset track during the movement.

[0013] In some technical solutions, optionally, the guide limit device includes a first guide limit plate and a second guide limit plate. The first guide limit plate is arranged on the frame. The second guide limit plate is arranged on the frame. At least a part of the receiving hopper is arranged between the first guide limit plate and the second guide limit plate.

[0014] In this technical solution, by setting the first guide limit plate and the second guide limit plate, on the one hand, they can play a guiding role so that the receiving hopper can move more smoothly relative to the frame; on the second hand, they can play a limiting role to effectively prevent the receiving hopper from deviating from the preset trajectory during movement.

[0015] In some technical solutions, optionally, the material collection and transportation device further includes a driving device, which is disposed on the frame, connected to the receiving hopper, and is used to drive the receiving hopper to move relative to the frame.

[0016] In this technical solution, by setting up a driving device, the receiving hopper can be driven to move relative to the frame between the first extreme position and the second extreme position. The staff can adjust the position of the receiving hopper according to actual needs (under the receiving condition, the receiving hopper is in the first extreme position; under the walking condition, the receiving hopper is in the second extreme position), which is beneficial to improving the flexibility of the shovel plate part.

[0017] In some technical solutions, the driving device may include a connecting rod mechanism and a driving oil cylinder. The connecting rod mechanism is rotatably connected to the frame, and the connecting rod mechanism is rotatably connected to the receiving hopper. One end of the driving oil cylinder is rotatably connected to the frame, and the other end of the driving oil cylinder is rotatably connected to the connecting rod mechanism.

[0018] In this technical solution, through the cooperation between the connecting rod mechanism and the driving cylinder, the receiving hopper can be moved relative to the frame between the first extreme position and the second extreme position, and the staff can adjust the position of the receiving hopper according to actual needs.

[0019] Optionally, when the driving cylinder is in an extended state, the receiving hopper is in a first extreme position; when the driving cylinder is in a retracted state, the receiving hopper is in a second extreme position.

[0020] In some technical solutions, optionally, the connecting rod mechanism includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the frame, and the other end of the first connecting rod is rotatably connected to the driving cylinder. One end of the second connecting rod is rotatably connected to the receiving hopper, and the other end of the second connecting rod is rotatably connected to the first connecting rod.

[0021] In this technical solution, by driving the first connecting rod and the second connecting rod through the driving cylinder, the position of the receiving hopper can be accurately controlled. Under the receiving condition, the receiving hopper is in the first extreme position; under the walking condition, the receiving hopper is in the second extreme position.

[0022] In some technical solutions, optionally, the first hanging assembly includes a first chain. One end of the first chain is connected to the frame, and the other end of the first chain is connected to the belt conveyor.

[0023] In this technical solution, by setting the first chain, the belt conveyor can have a higher degree of freedom when the belt conveyor and the frame are in a connected state, effectively avoiding motion interference when the belt conveyor moves with the shovel part.

[0024] In some technical solutions, optionally, the milling drum includes a spiral drum and a plurality of picks. The spiral drum is rotatably arranged on the frame. The plurality of picks are arranged on the spiral drum.

[0025] In this technical solution, through the cooperation of the spiral drum and the cutting teeth, the milling drum can peel off the surface mineral (material) and throw the material into the receiving hopper. The shovel plate does not need to be equipped with a star wheel device and only plays a passive material collection role.

[0026] In some technical solutions, optionally, the material collection and transportation device further comprises a leveling mechanism, one end of which is rotatably connected to the receiving hopper, and the other end of which is connected to the receiving hopper via a second hanging assembly.

[0027] In this technical solution, the leveling mechanism can rotate relative to the collecting hopper. By providing the leveling mechanism, the material dropped from the shovel plate can be scraped flat, making it convenient for the crawler to walk.

[0028] A second aspect of the present invention provides a mining machine, comprising a machine body and the material collecting and transporting device in any of the above technical solutions, wherein the frame of the material collecting and transporting device is connected to the machine body.

[0029] Since the mining machine includes any of the material collection and transportation devices in the first aspect above, it has the beneficial effects of any of the above technical solutions, which will not be described in detail here.

[0030] Additional aspects and advantages of the technical solutions of the present invention will become apparent in the following description or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0042] Refer to the following Figures 1 to 7 A material collecting and transporting device 100 and a mining machine 200 are described according to some embodiments of the present invention.

[0043] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the material collecting and transporting device 100 includes a frame 110 , a shovel plate 120 , a belt conveyor 130 and a milling drum 150 .

[0044] The frame 110 can be understood as a main body frame. For the shovel plate 120, the belt conveyor 130 and the milling drum 150, the frame 110 mainly serves as a mounting carrier.

[0045] The shovel plate 120 includes a receiving hopper 121. The receiving hopper 121 is movably disposed on the frame 110, and the receiving hopper 121 can move relative to the frame 110. The receiving hopper 121 has a first limit position and a second limit position. The receiving hopper 121 can move relative to the frame 110 from the first limit position to the second limit position, or move relative to the frame 110 from the second limit position to the first limit position.

[0046] It should be noted that, in the material receiving condition, the material receiving hopper 121 is in the first extreme position; in the moving condition, the material receiving hopper 121 is in the second extreme position.

[0047] One end of the belt conveyor 130 is connected to the shovel plate 120, and the belt conveyor 130 is connected to the frame 110 through the first hanging assembly 140. The belt conveyor 130 serves as the first conveyor and can move relative to the frame 110. During the movement of the receiving hopper 121 relative to the frame 110 between the first limit position and the second limit position, the belt conveyor 130 can move relative to the frame 110 together with the receiving hopper 121. The receiving hopper 121 moves with the belt conveyor 130 to ensure continuous transportation of materials without leakage.

[0048] Optionally, one end of the belt conveyor 130 is rotatably connected to the receiving hopper 121 of the shovel plate 120. When the belt conveyor 130 moves relative to the frame 110 along with the shovel plate 120, the belt conveyor 130 and the receiving hopper 121 can rotate relative to each other, thereby ensuring continuous transportation of materials without leakage and avoiding motion interference.

[0049] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, one end of the first hanging assembly 140 is connected to the frame 110, and the other end of the first hanging assembly 140 is connected to the belt conveyor 130. Optionally, the belt conveyor 130 has a first end and a second end that are arranged opposite to each other, the first end is used to connect to the receiving hopper 121 of the shovel plate part 120, and the second end is the material discharge end. Optionally, the connection position between the first hanging assembly 140 and the belt conveyor 130 is set at a position close to the second end.

[0050] By providing the first hanging assembly 140 , the belt conveyor 130 can have a higher degree of freedom when the belt conveyor 130 is connected to the frame 110 , thereby effectively avoiding motion interference when the belt conveyor 130 moves with the shovel portion 120 .

[0051] Optionally, one end of the belt conveyor 130 is detachably connected to the shovel plate portion 120, which is convenient for staff to disassemble and assemble, and is conducive to maintenance or replacement.

[0052] Optionally, the belt conveyor 130 and the receiving hopper 121 of the shovel plate portion 120 are detachably connected by bolts, screws, pins or other forms of connectors, which is convenient and quick, and helps to improve the disassembly and assembly efficiency of the staff.

[0053] Alternatively, if Figure 1 and Figure 2 As shown, the belt conveyor 130 includes a support frame 131, at least two return rollers 132 and a transport belt 133. The support frame 131 is connected to the receiving hopper 121. The first hanging assembly 140 is used to connect the frame body 110 and the support frame 131. At least one return roller 132 is rotatably disposed at one end of the support frame 131, and at least one return roller 132 is rotatably disposed at the other end of the support frame 131, and the return roller 132 can rotate relative to the support frame 131. The transport belt 133 is an annular structure, and is sleeved on at least two return rollers 132, and the transport belt 133 and the return roller 132 are frictionally matched.

[0054] It should be noted that at least one folding roller 132 is used to connect to a driving member, and the driving member is used to drive the folding roller 132 to rotate, thereby causing the transport belt 133 to operate to transport the material.

[0055] Alternatively, if Figure 2 As shown, the belt conveyor 130 also includes a plurality of support rollers 134, which are rotatably disposed on the support frame 131. The support rollers 134 are disposed on the inner side (inside the annular structure) of the conveying belt 133, and the support rollers 134 can abut against the conveying belt 133 to support the conveying belt 133.

[0056] Optionally, a plurality of support rollers 134 are arranged at equal intervals on the support frame 131 to ensure the support effect of the support rollers 134 on the conveying belt 133, so that the conveying belt 133 can stably transport materials.

[0057] Optionally, a first buffer layer is provided on the outer wall of the support roller 134. The first buffer layer is a rubber layer. The first buffer layer is provided to reduce the wear of the support roller 134 and increase the service life.

[0058] The milling drum 150 is rotatably disposed on the frame 110, and the milling drum 150 can rotate relative to the frame 110. The milling drum 150 peels off the surface mineral material (material), and at the same time, the mineral material is thrown from the top of the milling drum 150 to the receiving hopper 121 through the symmetrical spiral structure of the milling drum 150 itself.

[0059] It should be noted that in Figure 1 In FIG. 1 , the “arc arrow” in the milling drum 150 indicates the rotation direction of the milling drum 150 (clockwise rotation). Figure 2In FIG. 1 , the “arc arrow” next to the milling drum 150 indicates the rotation direction of the milling drum 150 (clockwise rotation).

[0060] Optionally, the belt conveyor 130 is disposed on one side of the receiving hopper 121 , and the milling drum 150 is disposed on the other side of the receiving hopper 121 .

[0061] When the receiving hopper 121 moves from the second limit position to the first limit position, the receiving hopper 121 gradually approaches the milling drum 150. When the receiving hopper 121 is at the first limit position, the milling drum 150 is used to throw materials into the receiving hopper 121. The collected materials are finally transported out by the belt conveyor 130.

[0062] By arranging the milling drum 150 at the front end of the receiving hopper 121, in the receiving condition, the milling drum 150 can throw the material into the receiving hopper 121, and the shovel part 120 does not need to be provided with a star wheel device, and only plays a passive role in receiving the material. This design method is conducive to simplifying the structure of the shovel part 120, reducing the risk of failure, and improving the efficiency of receiving the material.

[0063] It should be noted that, between the first extreme position and the second extreme position, the first extreme position is closer to the milling drum 150, and the first extreme position is closer to the ground. Therefore, in the process of the receiving hopper 121 moving from the second extreme position to the first extreme position, the receiving hopper 121 gradually approaches the milling drum 150, and the receiving hopper 121 gradually approaches the ground; in the process of the receiving hopper 121 moving from the first extreme position to the second extreme position, the receiving hopper 121 gradually moves away from the milling drum 150, and the receiving hopper 121 gradually moves away from the ground.

[0064] In the material receiving condition, the material receiving hopper 121 is in the first extreme position, and the material receiving hopper 121 is in the working state (material receiving state); in the walking condition, the material receiving hopper 121 is in the second extreme position, and the material receiving hopper 121 is in the retracted state.

[0065] In the technical solution of the present invention, on the first aspect, a milling drum 150 is arranged at the front end of the receiving hopper 121 of the shovel plate part 120. Under the material collecting condition, the milling drum 150 can throw the material into the receiving hopper 121. The shovel plate part 120 does not need to be provided with a star wheel device, and only plays a role of passive material collecting. This design method is conducive to simplifying the structure of the shovel part 120, reducing the maintenance cost and failure risk caused by the star wheel device, and the material collection efficiency is higher; secondly, the collected materials are directly transported out through the belt conveyor 130, and there is no need to set a scraper conveyor between the shovel part 120 and the belt conveyor 130, which is conducive to reducing energy consumption, reducing the wear between the material and the transportation device (belt conveyor 130), and can also reduce the risk of failure points; thirdly, the receiving hopper 121 of the shovel part 120 can move relative to the frame 110 between the first extreme position and the second extreme position, and the position of the receiving hopper 121 is adjusted according to actual needs (under the material collection condition, the receiving hopper 121 is in the first extreme position; under the walking condition, the receiving hopper 121 is in the second extreme position), which is conducive to improving the flexibility of the shovel part 120; fourthly, the receiving hopper 121 and the belt conveyor 130 move with each other to ensure continuous transportation of materials without leakage.

[0066] In some embodiments, optionally, Figure 1 As shown, the material collection and transportation device 100 further includes a guide and limit device 160. The guide and limit device 160 is disposed on the frame 110. When the receiving hopper 121 moves from the first limit position to the second limit position, or from the second limit position to the first limit position, the guide and limit device 160 is used to guide and limit the receiving hopper 121.

[0067] It should be emphasized that in the process of moving the receiving hopper 121 from the second extreme position to the first extreme position, the receiving hopper 121 gradually approaches the milling drum 150 and the ground; in the process of moving the receiving hopper 121 from the first extreme position to the second extreme position, the receiving hopper 121 gradually moves away from the milling drum 150 and the ground.

[0068] Optionally, the guide and limit device 160 is a block structure or a plate structure. When the receiving hopper 121 moves relative to the frame 110 between the first limit position and the second limit position, the receiving hopper 121 can be offset against the guide and limit device 160. By providing the guide and limit device 160, the receiving hopper 121 can be guided and limited, ensuring the stability of the movement of the receiving hopper 121 relative to the frame 110, and effectively preventing the receiving hopper 121 from deviating from the preset track during the movement.

[0069] Optionally, the number of guide and limit devices 160 is at least one, that is, the guide and limit devices 160 can be one, two or more. Considering the guiding effect and limiting effect on the receiving hopper 121, the size of the occupied space and other factors, the guide and limit devices 160 are flexibly set according to actual needs.

[0073] In some embodiments, optionally, the guide and limit device 160 includes a first guide and limit plate 161 and a second guide and limit plate 162. The first guide and limit plate 161 is disposed on the frame 110. The second guide and limit plate 162 is disposed on the frame 110. At least a portion of the receiving hopper 121 is disposed between the first guide and limit plate 161 and the second guide and limit plate 162.

[0074] Optionally, the first guide limit plate 161 and the second guide limit plate 162 are arranged opposite to each other with a gap therebetween. At least a portion of the receiving hopper 121 is arranged in the gap (the gap between the first guide limit plate 161 and the second guide limit plate 162).

[0075] When the receiving hopper 121 moves between the first limit position and the second limit position relative to the frame 110, the receiving hopper 121 can abut against the first guide limit plate 161 or the second guide limit plate 162. By providing the first guide limit plate 161 and the second guide limit plate 162, on the one hand, a guiding function can be provided so that the receiving hopper 121 can move more smoothly relative to the frame 110; on the other hand, a limiting function can be provided to effectively prevent the receiving hopper 121 from deviating from a preset track during movement.

[0076] Optionally, the side of the first guide and limit plate 161 close to the second guide and limit plate 162 is a first arcuate surface, and the side of the second guide and limit plate 162 close to the first guide and limit plate 161 is a second arcuate surface. This design is conducive to improving the guiding and limiting effects of the guide and limit plates (the first guide and limit plates 161 and the second guide and limit plates 162) on the receiving hopper 121.

[0077] Optionally, a second buffer layer is provided on a side of the first guide limit plate 161 close to the second guide limit plate 162. A third buffer layer is provided on a side of the second guide limit plate 162 close to the first guide limit plate 161. The second buffer layer and the third buffer layer are rubber layers.

[0078] Providing the second buffer layer and the third buffer layer is helpful to reduce the wear on the guide limit plate and increase the service life.

The driving device 170 is disposed on the frame 110. The driving device 170 is connected to the receiving hopper 121, and the driving device 170 is used to drive the receiving hopper 121 to move relative to the frame 110.

[0083] By setting up the driving device 170, the receiving hopper 121 can be driven to move relative to the frame 110 between the first extreme position and the second extreme position. The staff can adjust the position of the receiving hopper 121 according to actual needs (under the receiving condition, the receiving hopper 121 is in the first extreme position; under the walking condition, the receiving hopper 121 is in the second extreme position), which is beneficial to improving the flexibility of the shovel part 120.

[0084] Optionally, the material collection and transportation device 100 further includes a mounting seat, and the driving device 170 is disposed on the mounting seat. In other words, the driving device 170 is connected to the frame 110 via the mounting seat. The mounting seat mainly serves as a mounting carrier.

Optionally, one end of the cylinder body is rotatably connected to the frame body 110; one end of the piston rod is rotatably connected to the connecting rod mechanism 171.

[0093] The driving cylinder 172 has an extended state and a retracted state. When the driving cylinder 172 is switched from the extended state to the retracted state, the overall length of the driving cylinder 172 becomes shorter; when the driving cylinder 172 is switched from the retracted state to the extended state, the overall length of the driving cylinder 172 becomes longer.

[0094] Optionally, when the driving cylinder 172 is in the extended state, the receiving hopper 121 is in the first extreme position; when the driving cylinder 172 is in the retracted state, the receiving hopper 121 is in the second extreme position.

[0095] Through the cooperation between the connecting rod mechanism 171 and the driving cylinder 172, the receiving hopper 121 can be moved relative to the frame 110 between the first extreme position and the second extreme position, and the staff can adjust the position of the receiving hopper 121 according to actual needs.

[0096] In some embodiments, optionally, Figure 1 and Figure 4 As shown, the connecting rod mechanism 171 includes a first connecting rod 1711 and a second connecting rod 1712. One end of the first connecting rod 1711 is rotatably connected to the frame 110, and the other end of the first connecting rod 1711 is rotatably connected to the driving cylinder 172. One end of the second connecting rod 1712 is rotatably connected to the receiving hopper 121, and the other end of the second connecting rod 1712 is rotatably connected to the first connecting rod 1711.

[0097] Optionally, one end of the first connecting rod 1711 is the first connection end of the connecting rod mechanism 171, and the other end of the first connecting rod 1711 is the third connection end of the connecting rod mechanism 171. One end of the first connecting rod 1711 is rotatably connected to the frame 110 via a first hinge shaft 1731. The other end of the first connecting rod 1711 is rotatably connected to the driving cylinder 172 via a fourth hinge shaft 1734.

[0098] One end of the second connecting rod 1712 is the second connection end of the connecting rod mechanism 171. One end of the second connecting rod 1712 is rotatably connected to the receiving hopper 121 via a second hinge shaft 1732. The other end of the second connecting rod 1712 is rotatably connected to the first connecting rod 1711 via a fifth hinge shaft 1735.

[0099] Optionally, the fifth hinge axis 1735 is disposed between the first hinge axis 1731 and the fourth hinge axis 1734. The first hinge axis 1731, the second hinge axis 1732, the third hinge axis 1733, the fourth hinge axis 1734 and the fifth hinge axis 1735 are disposed in parallel.

[0100] It should be noted that the first connecting rod 1711 is a first articulated arm; the second connecting rod 1712 is a second articulated arm.

[0101] By driving the oil cylinder 172 to drive the first connecting rod 1711 and the second connecting rod 1712, the position of the receiving hopper 121 can be accurately controlled. Under the receiving condition, the receiving hopper 121 is in the first extreme position; under the walking condition, the receiving hopper 121 is in the second extreme position.

[0102] In some embodiments, optionally, Figure 1 and Figure 4 As shown, the first hanging assembly 140 includes a first chain 141. One end of the first chain 141 is connected to the frame 110, and the other end of the first chain 141 is connected to the belt conveyor 130.

[0103] Optionally, the first chain 141 is a round link chain.

[0104] By providing the first chain 141 , when the belt conveyor 130 and the frame 110 are in a connected state, the belt conveyor 130 can have a higher degree of freedom, thereby effectively avoiding motion interference when the belt conveyor 130 moves with the shovel portion 120 .

[0105] In some embodiments, optionally, Figure 1 and Figure 3 As shown, the milling drum 150 includes a spiral drum 151 and a plurality of picks 152. The spiral drum 151 is rotatably disposed on the frame 110, and the spiral drum 151 can rotate relative to the frame 110. The plurality of picks 152 are disposed on the spiral drum 151. The picks 152 can rotate relative to the spiral drum 151.

[0106] Through the cooperation between the spiral drum 151 and the cutting teeth 152, the milling drum 150 can peel off the surface mineral materials (materials) and throw the materials into the receiving hopper 121. The shovel plate part 120 does not need to be provided with a star wheel device and only plays a role of passive material collection.

[0107] Optionally, the ore is thrown from the top of the milling drum 150 to the receiving hopper 121 through the symmetrical spiral structure of the milling drum 150 itself. Optionally, the spiral drum 151 can rotate around its axis relative to the frame 110. The spiral drum 151 is a bilaterally symmetrical structure. Optionally, the spiral drum 151 includes a left spiral structure and a right spiral structure connected to each other, and the left spiral structure and the spiral direction are opposite to the spiral direction of the right spiral structure.

[0108] When the milling drum 150 rotates clockwise, the left spiral structure will push the mineral material (material) cut from the left side to the upper right, and the right spiral structure will push the mineral material cut from the right side to the upper left, eventually making the mineral material gather above the milling drum 150 and thrown into the receiving hopper 121.

[0109] The rotation speed of the milling drum 150 affects the speed and force of the material being thrown. A higher rotation speed will give the material a greater centrifugal force and axial speed, which is more conducive to throwing the material into the receiving hopper 121, but it is also necessary to consider the characteristics of the material, such as particle size, viscosity, etc. If the particle size of the material is large or the viscosity is strong, it may be necessary to appropriately adjust the pitch and depth of the spiral structure and the rotation speed of the milling drum 150 to ensure that the material can be thrown smoothly without accumulation or clogging on the surface of the milling drum 150.

[0110] In some embodiments, optionally, Figure 1 , Figure 2 and Figure 4 As shown, the material collecting and transporting device 100 further includes a ground leveling mechanism 181 . One end of the ground leveling mechanism 181 is rotatably connected to the receiving hopper 121 , and the other end of the ground leveling mechanism 181 is connected to the receiving hopper 121 via a second hanging assembly 182 .

[0111] Optionally, the ground leveling mechanism 181 includes a ground leveling floor. One end of the ground leveling floor is rotatably connected to the receiving hopper 121 , and the other end of the ground leveling floor is connected to the receiving hopper 121 via a second hanging assembly 182 .

[0112] The leveling mechanism 181 can rotate relative to the receiving hopper 121. By providing the leveling mechanism 181, the material dropped from the shovel plate 120 can be scraped flat, making it convenient for the crawler (crawler walking part) to walk.

[0113] Optionally, the second suspension assembly includes a second chain. One end of the second chain is connected to the ground leveling mechanism 181 , and the other end of the second chain is connected to the ground leveling mechanism 181 .

[0114] Optionally, the second chain is a round link chain.

[0115] In some embodiments, optionally, the milling drum 150 strips the surface mineral materials, and at the same time, the mineral materials are thrown from above the milling drum 150 to the receiving hopper 121 through the symmetrical spiral structure of the milling drum 150 itself.

[0116] The opening width of the receiving hopper 121 matches the rotation speed and pitch of the milling drum 150 to ensure that the mineral material falls completely into the receiving hopper 121 .

[0117] The receiving hopper 121 is connected to the belt conveyor 130 via two long pins.

[0118] The rear end of the belt conveyor 130 is suspended on the main frame (frame 110) through two symmetrically arranged round-link chains (first chains 141).

[0119] The receiving hopper 121 serves as the main structure of the shovel plate portion 120 , and its front and rear positions are limited by limiting plates (guide limiting devices 160 ) at the front and rear ends.

[0120] During the material collection operation, the lifting cylinder (driving cylinder 172) extends, the whole machine (mining machine 200) moves forward, the milling drum 150 rotates clockwise, and the shovel plate 120 contacts the rear limit plate (second guide limit plate 162) due to its own gravity and the impact force of the mineral material.

[0121] During the material receiving operation, the lifting cylinder has contraction pressure, but the shovel plate 120 is still at the lowest position. When encountering large pieces of material at the bottom of the receiving hopper 121, the shovel plate 120 can slide upward along the rear limit plate, and the belt conveyor 130 moves backward under the suspension of the rear suspension chain (first chain 141) to ensure that the shovel plate 120 passes smoothly.

[0122] During the walking condition, the lifting cylinder is retracted, and the shovel plate part 120 is lifted up through the articulated arm (connecting rod mechanism 171). At the same time, the belt conveyor 130 moves backward under the suspension of the rear suspension round link chain.

[0123] The leveling mechanism 181 can flatten the ground surface after milling to ensure stable crawler walking. When the shovel plate 120 is lifted, the leveling mechanism 181 is downwardly acted upon by its own gravity, and the front part contacts the limit block to ensure that the scraping floor is lifted simultaneously with the shovel plate 120.

[0124] The advantages of the material collection and transportation device 100 of the present invention are: the shovel part 120 is used together with the belt conveyor 130, which is beneficial to reduce energy consumption and use costs compared with the scraper conveyor; the material is thrown through the milling drum 150, and the shovel part 120 does not need to be equipped with a star wheel device, and only plays a role of passive material collection; the collecting hopper 121 moves with the belt conveyor 130 to ensure continuous transportation of materials without leakage.

[0126] Optionally, the frame 110 and the body 210 are detachably connected to facilitate disassembly and assembly by staff, thereby facilitating maintenance or replacement.

[0127] Optionally, the mining machine 200 further includes a crawler walking unit, which is disposed at the bottom of the body 210. The crawler walking unit is used to realize the walking or moving function of the mining machine 200.
