Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] This utility model provides a coal testing sample transport device that solves the problems of low efficiency and poor sample uniformity caused by manual shaking.

[0034] The following is combined with Figures 1-3 The technical solution provided by this utility model will be described in more detail.

[0035] like Figures 1-3 As shown, the coal testing sample transport device provided by this utility model includes a vehicle body 1, a drive device located on the vehicle body 1, a rotating shaft 2, a rotating arm 3, and a tank 4. The drive device is fixed on the vehicle body 1 and is driven to the rotating shaft 2 to drive the rotating shaft 2 to rotate around its own axis. The rotating shaft 2 is hinged to the rotating arm 3, and the rotating arm 3 is rotatably connected to the side wall of the tank 4. A receiving plate 5 is fixed inside the tank 4 to fix the sample bottle. The tank 4 can swing under the drive of the rotating arm 3 to shake the sample bottle.

[0036] The vehicle body 1 refers to the mobile platform that carries the main structure of the transport device. It can be implemented using a welded steel frame structure, with casters installed at the bottom for mobility. The drive unit is the power output unit, which can be implemented using an electric motor and a reducer to provide stable rotational power. The shaft 2 is the power transmission component, which can be implemented using a medium carbon steel shaft, with its axis perpendicular to the direction of travel of the vehicle body 1. The tank 4 is the sample container, which can be implemented using a stainless steel cylinder, with a receiving plate 5 with a positioning structure fixed to its inner wall. The receiving plate 5 is the sample fixing component, which can be implemented using a grooved polymer sheet, with the groove shape matching the outer diameter of the sample bottle.

[0037] Specifically, the output shaft of the drive unit is connected to the rotating shaft 2 via a coupling. When the rotating shaft 2 rotates, it drives the rotating arm 3 to perform planar motion. The rotating arm 3 causes the tank 4 to produce a periodic tilting motion. The receiving plate 5 installed on the inner wall of the tank 4 fixes the sample bottle and prevents disorderly collisions during transportation. When the vehicle body 1 moves, the drive unit continues to work, keeping the tank 4 in a regular swinging motion. Under the combined action of gravity and inertia, the sample bottle is automatically shaken evenly. In this process, the mechanical transmission system and the container's swinging motion work together, and the transportation function and sample mixing process are completed simultaneously.

[0038] This solution integrates a drive system and a oscillation mechanism to achieve continuous sample mixing during transportation. Compared to manual shaking, the mechanically driven oscillation frequency and amplitude remain constant, eliminating the influence of human factors on the mixing quality. This improves detection efficiency, as the sample vials are mixed in a fixed state, avoiding sample precipitation and separation phenomena that occur during traditional transportation.

[0039] As an optional implementation, see Figures 1-3 As shown, the rotating arm 3 includes a connecting rod 31 and an arm 32, wherein the connecting rod 31 is hinged to the rotating shaft 2, the arm 32 is fixed to both ends of the connecting rod 31, and the arm 32 is rotatably connected to the opposite sides of the tank body 4.

[0040] The connecting rod 31 is connected to the rotating shaft 2 via a hinge point in the middle, converting the rotational motion output by the drive device into the reciprocating swing of the connecting rod 31. The arms 32 form symmetrically distributed rigid support structures at both ends of the connecting rod 31, uniformly transmitting power to the tank 4 through rotational connections with both sides of the tank 4. When the rotating shaft 2 drives the connecting rod 31 to swing, the arms 32 on both sides synchronously push the tank 4 to reciprocate around its own axis. The dual-support structure counteracts the torque offset caused by unilateral force application, ensuring the stability of the tank 4's swing trajectory. This solution, through the symmetrically distributed arms 32 forming a synchronous rotational connection with both sides of the tank 4, automatically balances the forces on both sides during power transmission, eliminating motion instability caused by single-point drive.

[0041] Through the above technical solution, this application enables the container 4 to maintain stable reciprocating oscillation during transportation, avoiding the problem of uneven shaking of the sample vials caused by uneven force. The dual-support drive structure ensures that the oscillation amplitude of the container 4 is consistent, improving the uniformity of sample mixing and reducing the need for manual shaking in the laboratory.

[0042] As an optional implementation, see Figures 1-3 As shown, there are two sets of rotating arms 3, which are rotatably connected to opposite ends of the tank body 4; the number and position of the rotating shafts 2 correspond one-to-one with the rotating arms 3.

[0043] This solution uses a rotating arm 3 structure with a symmetrical layout on both sides to enable the tank 4 to obtain synchronous driving force at both ends, eliminating the torque imbalance caused by single-sided driving and realizing the self-balancing characteristic of the tank 4 swinging.

[0044] As an optional implementation, see Figures 1-3 As shown, the tank 4 includes a tank body 41 and a lid 42, with the lid 42 covering the tank body 41.

[0045] The can body 41 refers to the rigid container body with a accommodating space. It can be made of metal or polymer material through welding or injection molding, and is used to support the sample bottle and provide physical support. The lid 42 refers to the closing component that matches the shape of the can body 41. It can be connected by a hinge or a snap-fit ​​structure to realize the opening and closing action. In the closed state, it forms a sealed interface with the can body 41 to prevent external contaminants from entering the interior of the can body 4.

[0046] The detachable cap 42 ensures efficient loading of sample vials while the mechanical locking structure between the rigid cap 42 and the can body 41 prevents displacement or loosening of the cap 42 due to transportation bumps.

[0047] As an optional implementation, see Figure 4 As shown, the receiving plate 5 is fixed to the inner wall of the tank body 4, and the receiving plate 5 is provided with a receiving groove or receiving hole 51 for fixing the sample bottle.

[0048] The receiving plate 5 is a supporting structure rigidly connected to the inner wall of the tank 4, which can be achieved by welding or bolting, and serves as the base for storing the sample bottles. The receiving groove or receiving hole 51 is a positioning structure formed on the receiving plate 5, which can be a groove or through hole formed by machining, used to limit the horizontal displacement of the sample bottles. Specifically, the receiving plate 5 is rigidly fixed to the inner wall of the tank 4. During transportation, when the tank 4 is swayed by external forces, this structure can prevent relative displacement between the receiving plate 5 and the tank 4 due to vibration. After the sample bottles are inserted into the receiving groove or receiving hole 51, they are physically constrained, preventing them from tipping over or colliding with each other during the swaying of the tank 4. Because the positions of multiple sample bottles are uniformly defined on the receiving plate 5, when the drive device drives the tank 4 to perform a swaying action, the swaying amplitude and frequency of all sample bottles remain consistent.

[0049] The above structure effectively fixes the sample bottles during transportation, eliminating the need to rearrange the bottles before manual shaking, avoiding uneven shaking force caused by bottle displacement, and reducing collision damage to the sample bottles during transportation.

[0050] See Figure 4 As shown, there are one or more accommodating plates 5, which are arranged at intervals along the axial direction of the tank body 4; the accommodating grooves or accommodating holes 51 are evenly spaced on the accommodating plates 5.

[0051] In this embodiment, the container 4 can simultaneously hold multiple (32 in the figure) general analytical experimental samples. Since the sample container can swing stably inside the container 4, it accelerates the cross-mixing and diffusion of the bottled coal sample during the mixing process, improves the mixing efficiency, and ensures that the coal sample reaches the optimal mixed uniform state before testing.

[0052] As an optional implementation, see Figures 1-3 As shown, a push rod 6 and a guardrail 7 are provided on the vehicle body 1, wherein the push rod 6 and the guardrail 7 are located on different sides of the vehicle body 1.

[0053] The push rod 6 refers to the rod-shaped component that allows the operator to apply pushing force to control the movement of the vehicle body 1. Specifically, it can be implemented as a straight rod, a U-shaped rod, or a grip structure with anti-slip texture, making it convenient for the operator to stand and apply force. The guardrail 7 refers to the protective structure set along the edge of the vehicle body 1. Specifically, it can be implemented as a metal frame, a mesh fence, or a baffle structure with cushioning material.

[0054] The above structure achieves a synergistic improvement in the ease of operation and the reliability of protection of the transport device during movement. The operator can complete the pushing and turning actions without adjusting the posture. At the same time, the guardrail 7 effectively isolates external interference, ensuring that the sample bottles remain stable during transportation and reducing the need for manual intervention.

[0055] As an optional implementation, see Figures 1-3 As shown, a drive box 8 is fixed on the vehicle body 1, and the drive device shafts 2 are connected by transmission. The transmission structure of the drive device shafts 2 is located inside the drive box 8, and the shafts 2 pass through the drive box 8.

[0056] The drive housing 8 refers to a sealed box structure fixed to the surface of the vehicle body 1. It can be implemented using welding or bolting, and its internal space is used to house the transmission structure. The transmission structure refers to the power transmission mechanism, which can be implemented using gear sets, pulley sets, or couplings, and is used to transmit the rotational power output from the drive unit to the rotating shaft 2. See also... Figure 5 As shown, Figure 5 The output end of the drive device (motor) is fixed with a drive gear 11, which meshes with a driven gear 12. The driven gear 12 is fixedly connected to the corresponding rotating shaft 2, thereby enabling the motor to drive the rotating shaft 2 to rotate.

[0057] The shaft 2 extending out of the drive housing 8 means that one end of the shaft 2 is connected to the transmission structure, and the other end extends through the side wall of the drive housing 8 to the outside. This can be achieved using a mechanical seal ring and bearing assembly, ensuring power output while maintaining a tight seal. Specifically, the drive housing 8 is fixedly connected to the vehicle body 1 to form an integral structure, with the transmission structure completely enclosed inside the housing. When the drive unit is running, its output shaft drives the transmission shaft to rotate via gear meshing, and the end of the transmission shaft forms a rigid connection with the shaft 2. The shaft 2 passes through the sealed bearing assembly on the side wall of the drive housing 8, transmitting rotational power to the rotating arm 3 connected to the outside of the housing while maintaining the airtightness of the housing. The internal space of the housing is isolated from the external environment, effectively preventing external dust particles from entering the transmission structure.

[0058] The aforementioned structure incorporates a fully enclosed drive housing 8, completely enclosing the transmission structure within a sealed space, eliminating direct contact between mechanical components and the external environment. This structural improvement fundamentally solves the problems of lubrication failure and component corrosion caused by environmental erosion in the transmission mechanism.

[0059] As an optional implementation, see Figures 1-3 As shown, a battery storage box 9 is fixed on the vehicle body 1. The battery storage box 9 is used to store the storage battery, and the storage battery is electrically connected to the drive device.

[0060] The battery storage box 9 refers to a closed box structure fixed to the vehicle body 1, which can be made of metal or engineering plastic. Its interior forms a space to restrict the movement of the battery. The battery is a rechargeable DC power supply device, which can be a lithium-ion battery or a lead-acid battery. It forms a closed circuit with the drive unit via wires. The motor of the drive unit is directly connected to the positive and negative terminals of the battery via wires, forming a power supply circuit independent of the external power grid. This allows the device to drive the rotating shaft 2 to rotate using the electrical energy stored in the battery even without an external power source, thereby maintaining the continuous swinging motion of the tank 4.

[0061] The integrated battery and dedicated storage structure ensure a stable power supply for the drive unit during mobile operations, eliminating the need for an external power source to perform sample mixing. This guarantees continuous power throughout the transportation process, preventing the tank from stopping its oscillation due to power outages, thus eliminating the need for manual mixing and improving sample mixing uniformity and detection efficiency.

[0062] As an optional implementation, see Figures 1-3 As shown, the bottom of the vehicle body 1 is equipped with swivel casters 10.

[0063] The swivel casters 10, with their independent steering function, enable the vehicle body 1 to respond in real time to changes in the direction of thrust while in motion, significantly reducing the operational space required for steering. This application solves the problem of low operational efficiency caused by insufficient mobility of the transport vehicle, enabling the vehicle body 1 to adapt to complex path environments and reducing the intensity of manual steering operations, thereby improving the continuity and stability of the sample transportation process.
