Description

Technical Field

[0001] This utility model belongs to the field of sampling device technology, and relates to a mobile sampling device, specifically a mobile sampling device for materials. Background Technology

[0002] Papermaking raw materials are generally bulk materials composed of sheet-like materials such as bagasse, reeds, bark, wheat straw, and bamboo. These materials are usually transported to the stockpile by belt conveyors and fall freely under gravity to form a cone-shaped stockpile. Due to differences in the density, shape, and size of the materials, gravity segregation is significant. Larger or heavier fragments tend to roll to the edge of the stockpile, while fine particles and dust tend to concentrate in the core area, resulting in a distinctly non-uniform distribution within the stockpile.

[0003] Currently, the industry commonly uses manual sampling: operators stand on the ground or climb to the surface of the stockpile and select surface or shallow material as samples based on experience. This method has the following key drawbacks: 1. Lack of representativeness of the samples: It is difficult for humans to reach the lower and core areas of the stockpile, and the samples cannot cover the material's layered structure, resulting in composition detection data that deviates significantly from the true values; 2. Safety risks: The stockpile structure is unstable, and personnel stepping on it can easily cause collapse accidents, and the dust environment is harmful to health; 3. Low sampling efficiency: When large-scale stockpiles require multiple sampling points, manual operation is time-consuming and labor-intensive, making it difficult to meet the needs of continuous production.

[0004] A search revealed a Chinese patent, CN205280423U, which discloses a material sampling machine. This machine uses a sampling hopper that can move back and forth on a trolley track, with a canvas bag located below the hopper. During sampling, the sampling hopper is positioned below the material drop point of the conveyor belt. While this patent addresses the issues of poor sample representativeness and low sampling efficiency, its installation on the ground necessitates a larger size to accommodate the width of the material pile, resulting in inconvenience in movement and high manufacturing costs.

[0005] Therefore, there is an urgent need to develop a sampling device that is easy to move, has a wide range of applications, and can perform full-section penetration sampling. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mobile sampling device for materials that is easy to move, improves sampling accuracy and efficiency, is safe and reliable to operate, and is easy to implement.

[0007] The technical problem solved by this utility model is achieved through the following technical solution:

Detailed Implementation

[0028] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0029] The innovative feature of the material mobile sampling device is that it includes a mobile chamber 2 and a sampling unit 5. The sampling unit is set at the top side of the mobile chamber. The sampling unit includes a mounting frame, a linear slide, a mounting plate 18, a horizontal rotary servo motor 15, a vertical rotary servo motor 16, a sampling rod 14, and a sampling spoon 12. The linear slide is installed on the crossbeam 17 of the mounting frame. The linear slide is driven by a walking servo motor 13. The mounting plate is slidably installed on the linear slide. The horizontal rotary servo motor is installed at the front end of the mounting plate. The vertical rotary servo motor is driven and installed at the lower part of the horizontal rotary servo motor. The sampling rod is driven and installed at the rear end of the vertical rotary servo motor. The sampling spoon is installed on the sampling rod.

[0030] The sampling unit also includes a lifting servo motor 10 and a sampling spoon cover 11. The sampling spoon cover is installed at the rear end of the mounting plate by the lifting servo motor and is located directly above the sampling spoon.

[0031] During operation, the sampling device is moved to the side of the conveyor belt, and the sampling unit begins to work: First, the traveling servo motor drives the mounting plate on the linear slide to move horizontally along the X-axis. In this embodiment, the travel distance of the mounting plate is 6 meters, which is the distance from the sampling point to the placement point. When the X-axis moves to the sampling point, the R-axis needs to be rotated to zero, that is, the position where the sampling spoon and the sampling spoon cover are opposite each other; the S-axis needs to be rotated to zero, that is, the position where the sampling spoon is facing upwards; the Z-axis needs to be at zero, that is, the position where the sampling spoon cover is not on the sampling spoon.

[0032] The R-axis is the direction in which the horizontal rotation servo motor drives the sampling spoon to rotate horizontally. The direction and angle of rotation are different at different positions. At the sampling point, it can only rotate in reverse, within the range of 0-90°; at the dispensing point, it can only rotate in the forward direction, within the range of 0-90°; at other positions, it is at the 0° position, that is, the position where the sampling spoon and the sampling spoon cover are opposite each other.

[0033] The S-axis is the direction in which the longitudinal rotation of the sampling spoon is driven by the longitudinal rotation servo motor. The direction and angle of rotation are different at different positions. It can rotate 180° forward and backward at the sampling point and the unloading point, and is at zero point at other positions, that is, the position where the sampling spoon is facing upward.

[0034] The Z-axis is the direction in which the sampling spoon cover is driven up and down by the lifting servo motor. After sampling is completed, the sampling spoon cover returns to the unloading point. The lifting servo motor drives the sampling spoon cover to descend and the cover is installed on the sampling spoon. All other positions are zero points, that is, the position where the sampling spoon cover is not on the sampling spoon.

[0035] The mobile house includes a mobile chassis, a house body, and jacks. The house body is installed on top of the mobile chassis. Jacks are installed at the four corners of the mobile chassis. A dustproof door 8 and a dustproof glass window 7 are installed on the side of the house body. A louvered fan 6 is installed above the dustproof glass window.

[0036] To facilitate staff to inspect the working conditions inside the mobile house or to enter the mobile house to maintain the equipment inside, this utility model also includes a ladder 1, which is connected to the side of the mobile house at the position corresponding to the dustproof door.

[0037] It also includes a packaging machine 19, which is installed inside the mobile housing, and a feed inlet 9 corresponding to the feeding hopper of the packaging machine is provided on the top of the mobile housing. It also includes a token dispensing unit 4, which is provided on the top of the mobile housing at a position corresponding to the feed inlet.

[0038] In this embodiment, both the packaging machine and the token dispensing unit are existing technologies, and the technology described in the patent publication CN223001857U, entitled "Automatic Packaging System for Materials with Traceability Function," can be directly used. In this prior art, the packaging unit corresponds to the packaging machine of this utility model, and the magnetic clasp pushing unit corresponds to the token dispensing unit of this utility model.

[0039] To avoid the impact of rain and snow on the collected materials, this utility model also includes a rain and snow shelter. A rain and snow shelter is installed above the feed inlet to prevent rain and snow from mixing into the collected samples.

[0040] It also includes a sample bag buffer unit 3, which includes a receiving part 20 and a feeding part 21. The receiving part is provided at the bottom of the packaging machine in the mobile room, and the feeding part is connected to the side of the receiving part. The feeding part extends out from the opening provided on the side of the mobile room.

[0041] In this embodiment, the sample bag buffer unit is prior art, and the technology described in the patent publication CN223087161U entitled "Intelligent Material Transfer Buffer Device" can be directly used. In this prior art, a portion of the unloading compartment corresponds to the receiving part of this utility model, and a portion of the feeding compartment corresponds to the feeding part of this utility model.

[0042] This utility model integrates sample collection, automatic bagging by the packaging machine, token binding, and buffer feeding functions into one unit, which greatly shortens the single operation cycle, meets the high-frequency sampling requirements of continuous production, and the sample taken is highly representative. The automatic token delivery and packaging avoid human interference with the accuracy of detection. It overcomes the three major industry problems of low representativeness, poor safety, and low sampling efficiency of bulk material sampling, and is especially suitable for stockpiles of loose materials with significant gravity segregation, such as papermaking raw materials.
