[0002] When using large quantities of coal, in order to ensure the quality of the coal, it is often necessary to receive sample coal for trial use and to sample and preserve the coal for easy traceability. Existing sampling tools cannot quickly adjust the sampling ratio. Therefore, we propose a rapid sampling device for coal blocks. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rapid coal sample collection device that can quickly sample coal and adjust the amount of coal sampled according to the actual situation, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a rapid sampling device for coal samples, comprising a mounting frame, wherein a belt conveyor is installed inside the mounting frame to transport the coal sample to a suitable position, a sampling slide is connected to the front surface of the mounting frame, the upper surface of the sampling slide is rotatably connected to a rotating rod via a bearing, a guide plate is fixedly connected to the rotating rod to collect the coal sample, and a power mechanism is connected to the lower end of the rotating rod to drive the rotating rod to rotate.
[0005] The design incorporates a guide vane to direct some of the coal for sampling. The guide vane is angle-adjustable, allowing for adjustments to the amount of coal sampled based on actual conditions, making it more practical. During sampling, the guide vane is tilted towards the center of the belt conveyor, guiding some coal through the vane into the sampling chute for sampling.
[0006] Furthermore, the power mechanism includes a second motor, which is fixedly connected to the lower surface of the mounting bracket at a corresponding position. The output shaft of the second motor passes through a circular hole opened on the mounting bracket and the sampling slide and is fixedly connected to the lower end of the rotating rod. The input end of the second motor is electrically connected to the output end of an external power supply through an external control switch group.
[0007] The motor is controlled by an external control switch group, which drives the rotating rod to rotate, thereby driving the guide plate to rotate.
[0008] Furthermore, the sampling device also includes a collection box, which is located on the lower side of the sampling slide. The right side surface of the collection box has equally spaced strip grooves, and partitions are slidably connected inside the strip grooves.
[0009] The design incorporates a collection box for collecting sampled coal, and a partition allows for the sealing of each collected sample, enabling multiple collection operations.
[0010] Furthermore, the sampling device also includes a feeding pipe. The feeding pipe is fixedly connected to the left side of the upper surface of the mounting frame. The inner left and right sides of the feeding pipe are rotatably connected to crushing rollers, respectively. The front surface of the feeding pipe is fixedly connected to a lubricating oil tank, which is filled with lubricating oil. Gears are respectively installed on the inner left and right sides of the lubricating oil tank. The two gears mesh, and the rear surfaces of the two gears are respectively fixedly connected to the front ends of round rods. The rear ends of the two round rods are respectively rotatably connected to corresponding positions inside the lubricating oil tank. The rear ends of the two round rods extend through round holes opened on the feeding pipe to the inside of the feeding pipe and are fixedly connected to the center position of the corresponding crushing roller. A motor is fixedly connected to the rear surface of the feeding pipe. The output shaft of the motor passes through a round hole opened on the feeding pipe and is fixedly connected to the center position of the left crushing roller. The input end of the motor is electrically connected to the output end of an external power supply through an external control switch group.
[0011] The design incorporates crushing rollers to crush the coal samples, facilitating subsequent sampling while simultaneously pulverizing the coal blocks. During crushing, an external control switch activates a motor, which in turn rotates the left crushing roller, which in turn drives the other crushing roller via gears, thus completing the crushing process.

[0016] Please see Figure 1-5 This embodiment provides a technical solution: a rapid sampling device for coal samples, including a mounting frame 1, a belt conveyor 2 installed inside the mounting frame 1, the belt conveyor 2 being used to transport the coal samples to a suitable position, a sampling slide 8 being connected to the front surface of the mounting frame 1, the upper surface of the sampling slide 8 being rotatably connected to a rotating rod via a bearing, a guide plate 10 being fixedly connected to the rotating rod, the guide plate 10 being used to collect the coal samples, and a power mechanism being connected to the lower end of the rotating rod, the power mechanism being used to drive the rotating rod to rotate.
[0017] The guide plate 10 is designed to guide a portion of the coal block for sampling. The guide plate 10 is angle-adjustable, allowing the amount of coal sampled to be adjusted according to actual conditions, making it more practical. When sampling is performed, the guide plate 10 is controlled to deflect towards the center of the belt conveyor 2, so that a portion of the coal is guided into the sampling chute 8 for sampling.
[0018] The power mechanism includes a second motor 9, which is fixedly connected to the lower surface of the mounting bracket 1 at a corresponding position. The output shaft of the second motor 9 passes through a circular hole in the mounting bracket 1 and the sampling slide 8 and is fixedly connected to the lower end of the rotating rod. The input end of the second motor 9 is electrically connected to the output end of an external power supply via an external control switch group.
[0019] The motor 29 is controlled by an external control switch group, which drives the rotating rod to rotate, thereby driving the guide plate 10 to rotate.
[0020] The sampling device also includes a collection box 11. The collection box 11 is located on the lower side of the sampling slide 8. The right side surface of the collection box 11 has strip grooves at equal intervals, and the partition 12 is slidably connected inside the strip grooves.
[0021] The collection box 11 is designed to collect the sampled coal, and the partition 12 is designed to seal the sample each time it is collected, so that the collection work can be carried out multiple times.
[0022] The sampling device also includes a feeding pipe 3. The feeding pipe 3 is fixedly connected to the left side of the upper surface of the mounting frame 1. The inner left and right sides of the feeding pipe 3 are respectively rotatably connected to the crushing rollers 5.

The input end of the motor 4 is electrically connected to the output end of the external power supply through an external control switch group.
[0023] The crushing roller 5 is designed to crush the sample coal, thereby crushing the coal blocks and facilitating subsequent sampling. When crushing is in progress, the motor 4 is controlled by an external control switch group, which drives the left crushing roller 5 to rotate, which in turn drives the other crushing roller 5 to rotate through the gear 6, thus carrying out the crushing work.
[0024] The working principle of the rapid coal sample collection device provided by this utility model is as follows: The motor 4 is controlled by an external control switch group, which drives the left crushing roller 5 to rotate. This, in turn, drives the other crushing roller 5 to rotate via the gear 6, thus performing the crushing operation. The sample coal block is then placed into the feed pipe 3, where it is crushed by the crushing roller 5 and falls into the belt conveyor 2 for transport. The motor 9 is controlled by an external control switch group, which drives the rotating rod to rotate, which in turn drives the guide plate 10 to rotate. The guide plate 10 is then shifted toward the center of the belt conveyor 2, so that some of the coal is guided through the guide plate 10 into the sampling chute 8 for sampling.
[0025] It is worth noting that in the sample coal block rapid sampling device disclosed in the above embodiments, the belt conveyor 2 is a forward-mounted belt conveyor, and the motor 4 and motor 9 are controlled by an external control switch group using a method commonly used in the prior art.
