Description

Technical Field

[0001] The present application relates to the technical field of coal sampling and preparation, and in particular to a sampling and preparation system for a coal sampling and preparation testing vehicle and a coal sampling and preparation testing vehicle. Background Art

[0002] A coal sample is a representative portion of coal taken according to regulations to determine certain coal characteristics. Coal sampling equipment typically includes large and small carts, a lifting screw sampling head, a primary feeder, a crusher, a reducer, and a sample bucket. These large, dispersed, and extensive equipment footprints result in high sampling costs and low efficiency.

[0003] In response to the above problems, there are corresponding improvements in the prior art. For example, a Chinese patent application with a publication date of 2013-03-20 and a publication number of CN102980786A discloses a vehicle-mounted mobile fully automatic coal sampling and preparation machine and a coal sampling and preparation method. The sampling and preparation machine comprises a vehicle chassis (1), a subframe, hydraulic legs (4, 8), a sampling device (7), a sample preparation device (3), a sample collection device, a sample discarding box (2), a hydraulic oil tank (5), a cooler (6) and an electric control cabinet (9). The subframe is arranged on the vehicle chassis (1), and the other components are installed on the subframe. The coal sampling and preparation machine integrates sampling, sample delivery, sample preparation and sample discarding, can provide accurate and reliable sample preparation for coal quality analysis and testing, and has the advantages of high work efficiency, wide application range, high degree of automation, safe and convenient operation, etc. The shortcomings of this solution are: due to layout limitations, it only has a single sample preparation device, and the sample quality is poor; at the same time, the sampling device is directly moved above the sample preparation device to transfer the sample, which can easily cause the sample to fall on other equipment, resulting in reduced reliability of other equipment, and further reduced reliability of coal sampling and preparation operations.

Therefore, this application provides a sampling system for a coal sampling and testing vehicle, which implements secondary sample preparation and improves coal sample quality. Furthermore, by adapting a material retaining cover to the sampling arm, the reliability of the sampling operation is improved, further enhancing the quality of the coal sample.

[0005] The embodiment of the present application provides a sampling system for a coal sampling and testing vehicle, comprising a vehicle body, wherein a sampling unit is provided in the vehicle body, wherein the sampling unit comprises a robotic arm and a primary sampling device and a secondary sampling device respectively provided on both sides of the robotic arm;

By arranging the waste material collection box below the secondary sample preparation device, the front and rear balance of the car body can be improved.

[0013] In some embodiments, the sampling arm includes a barrel and a sampling mechanism disposed in the barrel, the barrel is provided with a plurality of windows communicating with the outside along its height direction, and the plurality of windows may be covered with a sealing plate to control the sampling volume;

[0024] The bottom of the limit frame has a closing portion and an outlet portion. The closing portion is used to prevent the coal in the limit frame from falling. The outlet portion is long and is arranged corresponding to the first inlet, so that the discarded material gradually falls from the outlet portion to the first inlet under the drive of the transmission line group.

[0025] In some embodiments, the transmission line group includes a transmission chain and a plurality of push plates spaced apart on the sides of the transmission chain.

[0057] Example 1:

[0058] See Figure 1-3 , Figure 1 This is a schematic diagram of the structure of the sampling system in Example 1 of the present application in use; Figure 2 for Figure 1 A schematic top view of the structure, wherein the first L-shaped cover plate 207 and the second L-shaped cover plate 208 are omitted; Figure 3 for Figure 1 Schematic diagram of the structure of the vehicle bottom.

[0059] An embodiment of the present application provides a sampling system for a coal sampling and testing vehicle, including a vehicle body 200 , in which a sampling unit is disposed.

[0060] In one embodiment, the coal sampling unit includes a robotic arm 300 and a primary sample preparation device 400 and a secondary sample preparation device 600, which are located on either side of the robotic arm 300. The primary sample preparation device 400 and the secondary sample preparation device 600 implement secondary sample preparation, meeting the national standard requirement of "sub-sample merging followed by sample preparation," thereby improving coal sample quality.

[0061] In addition, the first-level sampling device 400 and the second-level sampling device 600 are respectively arranged on both sides of the robotic arm 300, which facilitates the operation of the robotic arm 300 and improves the weight balance on both sides of the robotic arm 300, thereby improving the stability and safety of the car body 200 during movement, thereby making the sampling system suitable for movement and improving the flexibility of coal sampling.

[0062] In one embodiment, a sampling arm 310 is detachably provided at the end of the robotic arm 300 , and the robotic arm 300 is used to drive the sampling arm 310 to extend into the coal for sampling, thereby improving the automation of coal sampling.

[0063] Furthermore, the sampling arm 310 and the end of the robotic arm 300 are detachably connected, so that the end of the robotic arm 300 can be replaced with different sampling arms 310 and different execution end mechanisms according to the requirements of coal sampling, thereby achieving different operations.

[0064] In one embodiment, the sampling arm 310 includes a cylinder 311 and a sampling mechanism disposed in the cylinder 311. The cylinder 311 is provided with a plurality of windows 312 that penetrate the interior thereof along its height direction, and the sample collected by the sampling mechanism can overflow the sampling arm 310 through the window 312. The window 312 can be covered with a closing plate, thereby achieving control of the sampling volume by closing the windows 312 at different heights, and the operation is convenient.

[0065] It is understandable that the sampling mechanism in the sampling arm 310 can be a conventional sampling mechanism in the art, such as a spiral impeller.

[0066] In one embodiment, the robot arm 300 is a six-axis robot arm 300, which can improve the degree of freedom of operation and achieve more operations.

[0067] In one embodiment, the primary sample preparation device 400 includes a crusher 420 and a reducer 430. The crusher 420 is used to crush the sample. The reducer 430 is arranged below the crusher 420 and is connected to the crusher 420 and is used to prepare a primary reduced sample.

[0068] In one embodiment, the first-level sampling device 400 also includes a material blocking cover 410, which is arranged on the crusher 420 and is adapted to the sampling arm 310. The material blocking cover 410 is used to guide the sample collected by the sampling arm 310 into the crusher 420, thereby preventing the sample collected by the sampling arm 310 from falling and affecting the reliability of other devices, improving the reliability of the sampling operation, and ensuring that all the sampled samples fall into the crusher 420, thereby avoiding sample loss during docking, thereby improving the quality of the coal sample.

[0069] In one embodiment, the material blocking cover 410 includes a material blocking portion 411 and a flow guiding portion 412 .

[0070] In one embodiment, the material blocking portion 411 is vertically arranged, with both ends in the height direction being through, and a semi-enclosed structure in the circumferential direction. The robotic arm 300 can drive the sampling arm 310 at its end to embed into the material blocking portion 411, and make the window 312 of the sampling arm 310 blocked by the inner wall of the material blocking portion 411, so that when the sampling arm 310 outputs the sample, the sample is prevented from falling from the window 312. Even if there is a fallen sample, it can still fall into the crusher 420 through the cooperation of the material blocking portion 411 and the guide portion 412, thereby avoiding the loss of the sample during docking, thereby improving the quality of the coal sample.

[0071] At the same time, the through end and the semi-enclosed structure of the material blocking portion 411 improve the compatibility of the material blocking portion 411 with various types of sampling arms 310 , thereby improving the versatility of the material blocking cover 410 .

[0072] Preferably, the material blocking portion 411 circumferentially includes a flat plate and curved plates extending from both sides of the flat plate, an opening for the sampling arm 310 to enter is formed between the two curved plates, and the two curved plates are bent relative to each other to form an embracing shape, thereby expanding the internal space of the material blocking portion 411, facilitating the sample to fall from between the sampling arm 310 and the material blocking portion 411, and at the same time adapting to the funnel-shaped guide portion 412 arranged thereunder.

[0073] In one embodiment, the guide portion 412 is located at the end of the material blocking portion 411 and is funnel-shaped, thereby guiding the sample and avoiding sample loss during docking, thereby improving the quality of the coal sample.

[0074] In one embodiment, the end of the robotic arm 300 may be detachably provided with a first actuator 320 or a second actuator 330 .

[0075] In one embodiment, the secondary sample preparation device 600 includes a reduction table 610, and the robotic arm 300 is used to transfer multiple primary reduction samples to the reduction table 610 through the first actuator 320, and to mix the multiple primary reduction samples in the reduction table 610 through the second actuator 330 to prepare secondary reduction samples, so as to further improve the uniformity of the samples, improve the detection accuracy, and realize fully automated operation, thereby improving the safety and efficiency of sampling.

[0076] In one embodiment, the secondary sample preparation device 600 further includes a conveyor belt and a flattening mechanism. The conveyor belt, along its conveying direction, sequentially passes through the exit of the reduction stage 610 and the flattening mechanism. The flattening mechanism is used to flatten the sample on the conveyor belt, resulting in a flattened state for the final test sample, which facilitates improved test accuracy. Preferably, the conveyor belt passes through the testing port, and the end of the conveyor belt serves as the discard port of the secondary sample preparation device 600. This allows flattening, testing, and discarding to be performed using a single conveyor belt, resulting in a compact structure.

[0077] This setup is particularly suitable for testing samples using a visual coal quality detector, such as an X-ray fluorescence coal quality detector, which can greatly improve detection accuracy.

[0078] In one embodiment, a sample collecting box 700 is provided below the carriage body 200 corresponding to the first-level sample preparation device 400. The sample collecting box 700 is connected to the first-level sample preparation device 400 to collect the first-level reduced samples and then transfer them to the second-level sample preparation device 600, thereby improving the efficiency of coal sampling.

[0079] In one embodiment, a rotary conveyor belt 710 is provided in the sample collection box 700, and a plurality of supporting plates are provided on the rotary conveyor belt 710. The supporting plates are used to place sample barrels 720, and the plurality of sample barrels 720 are driven by the rotary conveyor belt 710 to move one by one and connect with the primary sample preparation device 400, so as to realize the differentiated collection of the first-stage reduction samples collected at different positions, thereby facilitating the centralized completion of sampling work in different areas, and then replacing the end mechanism of the robotic arm 300 to perform secondary reduction sampling, which can improve the sampling efficiency.

[0080] The rotary conveyor belt 710 may be a conveyor chain, and the sample barrel 720 may be detachably connected to the supporting plate to improve its stability in moving with the rotary conveyor belt 710 .

[0081] In one embodiment, the carriage body 200 is provided with a first area 210 and a second area 220 isolated from each other along its width direction, so that the first area 210 and the second area 220 have a longer space, thereby facilitating the side-by-side arrangement of multiple devices and facilitating maintenance.

[0082] Furthermore, the first area 210 and the second area 220 are respectively located on both sides of the vehicle body 200 , so that when the vehicle body 200 is set on the vehicle, it is convenient for the vehicle to be driven to a designated position for operation.

[0083] One of the first area 210 and the second area 220 is provided with only the production unit, and the other area is provided with other units, such as a control unit and a power unit, thereby improving the dust protection effect.

[0084] Preferably, the first zone 210 is provided with a control zone 221 and a power zone 222 that are isolated from each other along the length direction of the vehicle body 200 .

[0085] The control unit is arranged in the control area 221 , and the control unit may include but is not limited to a power distribution cabinet 201 , a PLC control cabinet 202 , a robotic arm control cabinet 203 , and a quality inspection control cabinet 204 .

[0086] The power unit is disposed in the power area 222 , and the power unit includes a generator set 205 and a robotic arm power system 206 .

[0087] At this time, the manipulator control cabinet 203 is connected to the manipulator 300, the generator set 205 is used for power supply, the manipulator power system 206 is connected to the manipulator 300 and is used to control the movement of the manipulator 300, and the PLC control cabinet 202 is used to control the entire coal sampling process. Preferably, the manipulator power system 206 is an air compression system.

[0088] The mining and processing unit is arranged in the second area 220, thereby isolating the mining and processing operation area from the control area 221 and the power area 222, reducing the intrusion of coal dust and the like into the control area 221 and the power area 222, and realizing dust protection for the control unit and the power unit.

[0089] This approach reduces the dustproofing requirements for each device by isolating the first and second zones 210, 220, and the control and power zones 221, 222 of the first zone 210, thereby reducing costs. Furthermore, the allocation of the first and second zones 210, 220, and the zoning of the various devices improves ease of sampling, testing, and maintenance. The strategic layout of the various devices enhances the stability and safety of the vehicle body 200.

[0090] In one embodiment, the primary sample preparation device 400 and the secondary sample preparation device 600 are arranged on both sides of the robotic arm 300 along the length direction of the second zone 220, so that sampling by the robotic arm 300 and coordinated operation of the robotic arm 300 with the primary sample preparation device 400 and the robotic arm 300 with the secondary sample preparation device 600 can be achieved within a limited space. In addition, the weight distribution of the second zone 220 is made more reasonable, thereby improving the stability and safety of the vehicle body 200 during movement.

[0091] In one embodiment, the generator set 205 and the robotic arm 300 are correspondingly arranged in the width direction of the vehicle body 200, further balancing the weight of the first area 210 and the second area 220, that is, improving the left-right balance of the vehicle body 200, thereby improving the movement stability and safety of the vehicle body 200 when moving, such as when mounted on a vehicle.

[0092] It should be noted that the power units and control units provided in the first area 210, such as the generator set 205, the robotic arm power system 206, and various control units, are relatively regular in appearance, and have high integration and compactness; the sampling and processing units provided in the second area 220, such as the robotic arm 300, the first-level sample preparation device 400, the second-level sample preparation device 600, etc., are all different in appearance, and the robotic arm 300 requires a certain amount of space for movement; and the weight of the generator set 205 is much greater than that of other devices.

[0093] Therefore, in one embodiment, the width of the first region 210 is smaller than the width of the second region 220, that is, the area of ​​the first region 210 is smaller than the area of ​​the second region 220, which facilitates the installation of various devices. Furthermore, the second region 220 has a larger area, providing a larger movement space for the robotic arm 300, facilitating its operation. Furthermore, when the centers of gravity of the first region 210 and the second region 220 are both at their centers, the moment arm of the first region 210 is smaller than the moment arm of the second region 220, while the weight of the first region 210 is much greater than the weight of the second region 220. This facilitates the left and right balance of the vehicle body 200, improving the smoothness and safety of the vehicle body 200 when it is moved, for example, on a vehicle.

[0094] See Figure 4-5 , Figure 4 Schematic diagram of the structure of the waste material recovery device and the sample collection box 700 in Example 1 of the present application; Figure 5 This is a partially enlarged structural schematic diagram of the waste material recovery device in an embodiment of the present application.

[0095] In one embodiment, a waste material collection box 800 is provided below the vehicle body 200 corresponding to the secondary sample preparation device 600, and the waste material collection box 800 is connected with the primary sample preparation device 400 and the secondary sample preparation device 600 to realize real-time collection of waste materials, thereby avoiding direct discharge of waste materials, polluting the environment, or even mixing into the area to be sampled, affecting the accuracy of detection.

[0096] At the same time, the waste material collection box 800 is heavier, and the secondary sample preparation device 600 is lighter than the primary sample preparation device 400. By setting the waste material collection box 800 below the secondary sample preparation device 600, the front and rear balance of the car body 200 can be improved. Moreover, the waste material collection box 800 is basically located on the diagonal line of the power unit (mainly the generator set 205), which can improve the left and right balance of the car body 200, so that when the car body 200 moves, for example, when it is mounted on a vehicle, the movement stability and safety are improved.

[0097] In one embodiment, the reducer 430 of the primary sample preparation device 400 is provided with two outlets, one of which faces the conveyor 810 to convey the reduced waste to the waste collection box 800, and the other faces the sample collection box 700 to collect the reduced samples. For example, the two outlets of the reducer 430 are respectively provided with a discharge guide cylinder, one of which faces the conveyor 810, and the other of which faces the sample collection box 700.

[0098] In one embodiment, the waste collection box 800 has a first inlet and a second inlet. The first inlet is connected to the primary sample preparation device 400 via a transmission device 810, and the second inlet is provided to correspond to the waste outlet of the secondary sample preparation device 600. In a specific embodiment, the second inlet is provided to correspond to the end of the conveyor belt of the secondary sample preparation device 600.

[0099] In one embodiment, the first inlet is elongated, meaning that the coal waste can fall into the waste collection box 800 in multiple locations, rather than just one location within the waste collection box 800. This improves space utilization within the waste collection box 800, eliminates the need for frequent emptying, and thus enhances ease of use and the effectiveness of the device. Preferably, the first inlet extends along the length of the waste collection box 800, meaning that the coal can cover the space within the waste collection box 800 to the greatest extent possible.

[0100] In this case, the transmission device 810 includes a limit frame 811 and a transmission line assembly disposed within the limit frame 811. The bottom of the limit frame 811 has a closed portion and an outlet portion. The closed portion is used to prevent the coal within the limit frame 811 from falling out. The outlet portion is elongated and arranged corresponding to the first inlet. The transmission line assembly transmits along the length of the waste collection box 800, and the bottom is hollowed out and covers the first inlet. The transmission line assembly is connected to a drive member and is driven by the drive member to reciprocate, so that the coal gradually falls from the outlet portion to the first inlet under the drive of the transmission line assembly. Therefore, while the transmission line assembly remains in an unchanged working state, the coal can be gradually accumulated at various positions in the waste collection box 800 along the transmission direction. This improves the space utilization of the waste collection box 800 and reduces the frequency of dumping of the waste collection box 800, thereby improving the convenience of use of the device and enhancing the actual use effect. At the same time, the operation and control of the transmission line assembly are simple.

[0101] During use, the coal waste is first accumulated at the front end of the first entrance. As the amount of coal increases to be basically flush with the bottom of the transmission line group, the coal transported subsequently cannot fall at this position, but moves with the transportation line group to fall farther, thereby achieving distribution and accumulation at various positions of the waste collection box 800, thereby improving the space utilization rate of the waste collection box 800.

[0102] In one embodiment, the transmission line assembly includes a transmission chain 812 and multiple push plates 813 spaced apart on the sides of the transmission chain 812. The transmission chain 812 is in transmission connection with a driving member. The multiple push plates 813 fit within a limiting frame 811 to form multiple pushing spaces. Driven by the transmission chain 812, the multiple pushing spaces move to push the coal to the first inlet. The transmission chain 812 is preferably a roller chain.

[0103] It should be noted that the coal is in granular form and is easily jammed due to squeezing when being pushed forward through the transmission line group, resulting in it not being able to fall off immediately.

[0104] This method forms a larger pushing space through the push plate 813 and the limit frame 811, which can reduce the risk of coal getting stuck in the transportation line group during transportation and improve transportation reliability; and the longer discard route formed by the longer first entrance and the longer exit part allows the stuck coal pile to be vibrated during the movement of the transmission equipment 810 and loosen and fall, achieving complete discard; even if it is stuck and cannot be removed, only the independent unit of the transmission chain 812 and the push plate 813 at the corresponding position can be disassembled and replaced, reducing maintenance costs.

[0105] In one embodiment, the second inlet is located at a position of the waste collection box 800 away from the outlet of the reduction table 610, so as to facilitate the setting of the conveyor belt of the secondary sample preparation device 600. At the same time, the transmission equipment 810 of the waste recovery device and the conveyor belt of the secondary sample preparation device 600 can also be arranged in parallel above the waste collection box 800, thereby improving space utilization.

[0106] In one embodiment, the sampling unit further includes a rack 900, which is used to accommodate the sampling arm 310, the first actuator 320 and the second actuator 330, so as to facilitate the robotic arm 300 to replace the sampling arm 310, the first actuator 320 and the second actuator 330 in a timely manner during the sampling process, thereby improving the sampling efficiency.

[0107] Preferably, the rack 900 is arranged at one end of the first-level sample preparation device 400 away from the robotic arm 300. It is within the range of movement of the robotic arm 300, which allows the end mechanism to be replaced while avoiding affecting the routine operation of the robotic arm 300, further ensuring the efficiency of sampling and testing.

[0108] In one embodiment, the storage rack 900 is provided with a plurality of vertical accommodating spaces, and a card interface 910 for clamping the sampling arm 310 or the first actuator 320 or the second actuator 330 is provided at the top of the vertical accommodating space, so as to facilitate the storage of the sampling arm 310, the first actuator 320 and the second actuator 330 in a vertical state in the storage rack 900, and the sampling arm 310, the first actuator 320 and the second actuator 330 in the vertical state are convenient for the automatic installation or disassembly of the robotic arm 300.

[0109] Since the rack 900 is arranged in the second zone 220 and directly faces the sampling area, coal can easily fall from above into the sampling arm 310, the first actuator 320 and the second actuator 330 in the rack 900, causing damage or affecting the detection accuracy. Therefore, preferably, the top of the card interface 910 is covered with a removable top cover.

[0110] In one embodiment, the sampling unit further includes a password packaging table 620, which is disposed at one end of the reduction table 610 close to the robotic arm 300, and a closable sample barrel 720 is disposed on the password packaging table 620. The closable sample barrel 720 is used to store part of the samples in the reduction table 610 to preserve the samples.

[0111] See Figure 8-9 , Figure 8 This is a structural diagram of the first actuator 320 in an embodiment of the present application; Figure 9 Schematic diagram of the structure of the second actuator 330 in the embodiment of the present application.

[0112] In one embodiment, the robotic arm 300 transfers the sample barrel 720 between the sample collection box 700 and the reduction stage 610 via the first actuator 320, transfers the sample in the sample barrel 720 to the reduction stage 610, and seals the sealable sample barrel 720 via the first actuator 320. For example, the first actuator 320 includes a gripper 331 for grasping the sample barrel 720 and a suction cup 322 for removing the cover 630 of the sample barrel 720. The suction cup 322 can be disposed on the arm of the gripper 331, or at any location that can accommodate both the gripper 331 and the suction cup 322.

[0113] The robotic arm 300 extends into the reducing platform 610 through the second actuator 330 and stirs and mixes the sample in the reducing platform 610, and grabs a portion of the sample and puts it into the sealable sample barrel 720. For example, the second actuator 330 includes a stirring member for stirring the sample and a grabbing member for grabbing the sample.

[0114] In one embodiment, the stirring element of the second actuator 330 is a stirring plate 331, which is driven by a robotic arm to stir. The gripping element includes a receiving tube 332, a push-pull rod 333, and a transmission linkage 334. The push-pull rod 333 drives the receiving tube 332 away from or toward the stirring plate 331 via the transmission linkage 334, enabling the receiving tube 332 to open and close to accommodate and seal the sample. Driven by the robotic arm, the receiving tube 332 is then moved to the top of the sample barrel 720 on the password packaging table 620.

[0115] In one embodiment, the car body 200 includes a bottom plate, two side plates arranged along its length, and a first partition plate arranged on the bottom plate. The two side plates and the first partition plate separate the car body 200 into a first area 210 and a second area 220. The structure is simple, the assembly is convenient, and it is convenient to set the first L-shaped cover plate 207 and the second L-shaped cover plate 208 by hinged connection with the top of the first partition plate.

[0116] The top of the first partition is rotatably connected to the first L-shaped cover 207 and the second L-shaped cover 208, and the first L-shaped cover 207 is used to cover the first area 210, and the second L-shaped cover 208 is used to cover the second area 220, so that when the first L-shaped cover 207 and the second L-shaped cover 208 are opened, the front of the first area 210 and the second area 220 can be unobstructed, and the top space of the first area 210 and the second area 220 can be greatly expanded, thereby facilitating operation and maintenance.

[0117] Example 2:

[0118] See Figure 6-7 , Figure 6 This is a schematic diagram of the state of sampling and testing coal loaded in a train carriage according to Example 2 of the present application; Figure 7 This is a schematic diagram of the state of coal pile sampling and detection in Example 2 of the present application.

[0119] Based on Example 1, this embodiment provides a coal sampling and testing vehicle, including a cab-frame assembly 100 and the sampling system of Example 1, and the vehicle body 200 of the sampling system is arranged on the frame of the cab-frame assembly 100, thereby realizing the on-vehicle movement of the sampling system, and can move freely in a variety of sampling environments, thereby improving the flexibility of coal sampling.

[0120] In one embodiment, the coal sampling and testing vehicle further includes a detection device 500, which is disposed within the vehicle body 200 of the sampling and testing system. This allows the sampling and testing system and the detection device 500 to be integrated into the same vehicle. This not only reduces the footprint of coal sampling and testing, but also significantly shortens the time from sampling and testing to sample testing, thereby improving sampling and testing efficiency and the accuracy of sample moisture testing. Preferably, the detection device 500 is disposed between the robotic arm 300 and the secondary sampling and testing device.

[0121] In one embodiment, the cab-frame assembly 100 includes a vehicle power mechanism, and the vehicle power mechanism is disposed below the cab of the cab-frame assembly 100 , thereby facilitating an overall balanced setting of the vehicle and improving the stability and safety of the vehicle.

[0122] In one embodiment, a vehicle energy storage device 110 is provided along the width direction of the vehicle body 200 and corresponding to the waste material collection box 800 .

[0123] The vehicle energy storage device 110 is a fuel tank for fuel vehicles and a battery pack for electric vehicles, and is typically quite heavy. Coal sample preparation typically involves a reduction process, resulting in a high volume of waste material, and thus a relatively heavy waste collection box 800. By arranging the waste collection box 800 and the vehicle energy storage device 110 in alignment across the width of the vehicle body 200, the vehicle's left-right balance is improved, thereby enhancing both stability and safety.

[0124] In one embodiment, the generator set 205 and the robotic arm 300 are respectively located above the two rear wheels 120 of the cab frame assembly 100, that is, the generator set 205 and the robotic arm 300 with the heaviest weight in the vehicle body 200 are respectively located above the rear wheels 120, thereby improving the stability and safety of the vehicle.

[0125] In one embodiment, the sample collection box 700 and the waste material collection box 800 are respectively located on both sides of the corresponding rear wheels 120 of the cab frame assembly 100, which is convenient for installation, improves the balance of the vehicle, and further improves the stability and safety of the vehicle.
