Description

Technical Field

[0001] The utility model relates to the technical field of sampling, in particular to an on-line coal quality detection sampling device. Background Art

[0002] Coal is known as black gold and the food of industry. It has been one of the main energy sources used by the human world since the 18th century. Since the beginning of the 21st century, although the value of coal is not as great as before, it has been one of the indispensable sources of energy for our production and life for a long time, and thus has a high economic value. During the mining process in the mining area, detection equipment will be used to detect the coal quality.

[0003] Existing technology, for example, is a utility model for an automatic coal quality detection sampler, with authorization announcement number CN221404794U. The sampling head can automatically extend into the coal to sample, and after sampling, the coal can be automatically poured out through a linkage structure, facilitating the collection of coal samples. It has a simple structure and is easy to use.

[0004] Currently, there is a lack of equipment that can facilitate real-time sampling on coal conveyor belts for online analysis.

[0005] Therefore, in response to the above problems, a coal quality online detection sampling device is proposed to solve the above problems. Utility Model Content

[0006] Aiming at the deficiencies of the prior art, the utility model develops an on-line coal quality detection and sampling device, which can realize real-time sampling on a coal conveyor belt for on-line analysis.

[0007] The technical solution to the technical problem solved by the present invention is as follows: The present invention provides an online coal quality detection and sampling device, comprising: a U-frame provided with a vertical slot; a stepped slot rotatably connected to the U-frame; a stepped block disposed within the stepped slot, the stepped block connected to a power rod, the power rod matching the vertical slot; a mounting frame connected to the power rod; and an electric push rod connected to the mounting frame, the push rod of the electric push rod being connected to a sampling mechanism. When the power rod moves along the vertical slot, the sampling mechanism is moved vertically downward, sampling is performed, and subsequent detection is facilitated.

[0008] As an optimization, the sampling mechanism includes a mounting plate, which is rotatably connected to a set of upper connecting rods. The mounting frame is connected to symmetrical horizontal U-frames, which are respectively connected to corresponding V-plates. Adjacent V-plates are respectively connected to circular shafts distributed above and below. Each of the upper circular shafts is rotatably connected to an outer connecting rod, and each of the lower circular shafts is rotatably connected to an inner connecting rod. Each of the upper connecting rods is rotatably connected to a corresponding outer connecting rod, and each of the outer connecting rods and the inner connecting rods is rotatably connected to a sampling rod. By using sampling rods, the sampling rods are initially spaced apart from each other. When the sampling rods are inserted into the coal block, the electric push rods are controlled to retract, causing the sampling rods to move closer together, placing the larger coal block in the area formed by the group of sampling rods, thereby achieving sampling.

[0009] As an optimization, a camera is connected to the center of the mounting plate to facilitate remote observation of the sampling process and ensure successful sampling.

[0010] As an optimization, the U-frame is equipped with arc grooves and transverse grooves, which connect the transverse grooves and the vertical grooves. The power rod matches the transverse grooves and the arc grooves. By using the arc grooves and transverse grooves, when the power rod is in the transverse groove, the coal lumps fall into the area formed by the sampling rods and inner connecting rods, facilitating the transportation of the coal lumps. By controlling the extension of the electric push rod, a group of sampling rods are moved away from each other, expanding the area, and the coal lumps fall from the area formed by adjacent sampling rods and inner connecting rods, thus realizing the removal of samples.

[0011] As an optimization, the U-frame is connected to the motor via a motor bracket, the output shaft of the motor passes through the motor bracket, the output shaft of the motor is connected to a chute, and the power round rod is arranged in the chute. By adopting the motor to drive, the movement of the sampling mechanism is powered.

[0012] As an optimization, the U-frame is arranged on the upper side of the coal conveyor belt. The coal conveyor belt is centrally arranged below the U-frame, and the coal conveyor belt and the U-frame are pre-installed at appropriate positions in the coal conveying channel.

[0013] The effects provided in the content of the utility model are only the effects of the embodiments, rather than all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0014] (1) The device is provided with a vertical slot to facilitate the downward movement of the sampling mechanism for sampling, and a horizontal slot is provided to facilitate the removal of samples.

[0015] (2) This device uses an electric push rod to swing the sampling rod inward, grabbing the coal block into an area composed of a group of sampling rods, which is convenient for sampling and transportation.

[0016] (3) This device is driven by a motor to provide power for the movement of the sampling mechanism and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figures 1 to 6 As shown, Example 1: An online coal quality detection and sampling device includes: a U-frame 2 provided with a vertical slot 5; a stepped slot 8 rotatably connected to the U-frame 2; a stepped block 11 disposed within the stepped slot 8, the stepped block 11 being connected to a power rod 10, the power rod 10 matching the vertical slot 5; a mounting frame 12 connected to the power rod 10; an electric push rod 13 connected to the mounting frame 12, the push rod of the electric push rod 13 being connected to a sampling mechanism. When the power rod 10 moves along the vertical slot 5, the sampling mechanism is moved vertically downward to perform sampling, facilitating subsequent testing.

[0027] The model of the electric push rod 13 is SXTL.

[0028] The sampling mechanism includes a mounting plate 15, which is rotatably connected to a group of upper connecting rods 17. The mounting frame 12 is connected to a symmetrical horizontal U-frame 14, and the symmetrical horizontal U-frames 14 are respectively connected to corresponding V-plates 19. Adjacent V-plates 19 are respectively connected to circular shafts 22 distributed above and below. Each of the circular shafts 22 on the upper side is rotatably connected to an outer connecting rod 18, and each of the circular shafts 22 on the lower side is rotatably connected to an inner connecting rod 20. Each of the upper connecting rods 17 is rotatably connected to a corresponding outer connecting rod 18, and each of the outer connecting rods 18 and the inner connecting rods 20 are rotatably connected to a sampling rod 21. By using the sampling rods 21, in the initial state, the sampling rods 21 are separated from each other. When the sampling rods 21 are inserted into the coal block, the electric push rod 13 is controlled to retract, so that the sampling rods 21 are brought closer to each other, so that a larger coal block is in the area formed by a group of sampling rods 21, thereby achieving sampling.

[0029] The model of the motor 6 is servo motor 57AIS.

[0030] The U frame 2 is connected to the motor 6 through the motor bracket 7. The output shaft of the motor 6 passes through the motor bracket 7. The output shaft of the motor 6 is connected to the chute 9. The power round rod 10 is arranged in the chute 9. The motor 6 is used to drive the movement of the sampling mechanism.

[0031] The U frame 2 is arranged on the upper side of the coal conveyor belt 1. The coal conveyor belt 1 is centrally arranged below the U frame 2, and the coal conveyor belt 1 and the U frame 2 are pre-installed in appropriate positions of the coal conveying channel.

[0032] The workflow of this embodiment is:

[0033] In the initial state, the power rod 10 is at the uppermost end of the vertical slot 5.

[0034] Motor 6 is controlled to rotate, causing chute 9 to swing. This chute 9 drives power rod 10 to move along vertical slot 5. Power rod 10 drives step block 11 along step slot 8, keeping step slot 8 vertical. Power rod 10 drives mounting bracket 12, electric push rod 13, and sampling mechanism downward, allowing sampling rod 21 to be inserted into the coal on coal conveyor belt 1. Electric push rod 13 is controlled to retract, causing mounting plate 15 to move. Mounting plate 15 drives upper connecting rod 17 to swing. Upper connecting rod 17 drives outer connecting rod 18 to swing. Outer connecting rod 18 drives sampling rod 21 to swing. Sampling rod 21 drives inner connecting rod 20 to swing, allowing a larger coal lump to be within the area formed by the group of sampling rods 21. Motor 6 is controlled to rotate in the opposite direction, causing power rod 10 to be at the uppermost end of vertical slot 5, completing sampling.

[0035] Example 2: This example further elaborates on Example 1. The U-frame 2 is provided with an arc groove 4 and a transverse groove 3. The arc groove 4 connects the transverse groove 3 and the vertical groove 5. The power round rod 10 matches the transverse groove 3 and the arc groove 4. By using the arc groove 4 and transverse groove 3, when the power round rod 10 is in the transverse groove 3, the coal blocks fall into the area formed by the sampling rod 21 and the inner connecting rod 20, facilitating the transportation of the coal blocks. By controlling the extension of the electric push rod 13, a group of sampling rods 21 are moved away from each other, expanding the area. The coal blocks fall from the area formed by adjacent sampling rods 21 and inner connecting rods 20, realizing the removal of samples.

[0036] The workflow of this embodiment is:

[0037] In the initial state, if Figure 1 shown.

[0038] The motor 6 is controlled to rotate, and the motor 6 drives the chute 9 to swing. The chute 9 drives the power round rod 10 to move along the horizontal groove 3, the arc groove 4 and the vertical groove 5. When the power round rod 10 moves along the horizontal groove 3, the step groove 8 remains horizontal. The power round rod 10 drives the step block 11 to move along the step groove 8. When the power round rod 10 moves along the arc groove 4, the step block 11 drives the step groove 8 to swing. The power round rod 10 drives the mounting frame 12, the electric push rod 13 and the sampling mechanism to move to realize sampling.
