Description

Technical Field

[0001] This utility model relates to the technical field of material flow sampling devices, and more specifically, to a material flow sampling device for a belt conveyor head pulley. Background Technology

[0002] In industries such as mining and resource development, belt conveyors are commonly used to transport materials. To achieve quality control, it's essential to analyze the properties and quality of materials at each production stage during conveyor transport. Currently, this involves manually picking up a certain amount of material from the belt at regular intervals. This method is labor-intensive, inefficient, and typically only captures surface or localized material, resulting in low accuracy and unrepresentative sample data, leading to increased costs for subsequent analysis and processing. Furthermore, sampling personnel must be close to the running belt and materials, posing safety hazards such as being caught in the belt or injured by falling material. Utility Model Content

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1

[0034] from Figure 1-4 As can be seen, the belt conveyor head wheel material flow sampling device of this embodiment includes a mounting base 1, which is connected to the front wall 4 of the belt transfer funnel by welding or bolts.

[0035] The surface of the mounting base 1 is provided with a drive mechanism 2, and the bottom of the drive mechanism 2 is connected to a sampling mechanism 3;

[0036] The sampling mechanism 3 includes a sampling tube 31, the upper end of which is connected to a sampling hopper 32. The upper end of the sampling tube 31 is inclined and the lower end is vertical. The upper end of the sampling tube 31 is connected to the sampling hopper 32 through a flange 34.

[0037] The lower end of the sample delivery tube 31 is provided with a sample delivery port 311, and a storage container 33 is placed at the bottom of the sample delivery port 311;

[0038] The driving mechanism 2 can drive the sampling mechanism 3 to swing around the center line of the sample inlet 311;

[0039] The drive mechanism 2 is either a manual drive mechanism 21 or an electric drive mechanism 22.

[0040] This embodiment uses a manual drive mechanism 21, which includes a bushing 211.

[0041] The mounting base 1 has a hole in the middle, and a bushing 211 is installed in the hole. The mounting base 1 has two sets of limit pins 212 and two mounting base positioning holes 213 symmetrically arranged on both sides with the bushing 211 as the center line.

[0042] A pin 214 is installed on the inner ring of the bushing 211. The lower end of the pin 214 is welded and fixed to the sample delivery tube 31. The upper end of the pin 214 passes through the bushing 211 and extends to the upper part of the mounting base 1. A rotating disk 215 is provided on the mounting base 1. The rotating disk 215 is fixedly fitted on the outer ring of the pin 214. A rotating handle 216 is connected to the outer ring of the rotating disk 215. A handle 219 is inserted into one end of the rotating handle 216. The handle 219 can be quickly removed.

[0043] The upper surface of the rotating disk 215 is provided with double nuts 217; the upper outer ring of the bushing 211 is provided with a threaded structure, and the shaft pin 214 is assembled with the mounting base 1 through the double nuts 217; the upper part of the bushing 211 is also provided with a cotter pin hole.

[0044] Mounting seat 1 is horizontally positioned outside the front wall 4 of the belt transfer funnel, and bushing 211 is vertically welded downwards along the surface of mounting seat 1.

[0045] The bushing 211 and the pin 214 are clearance-fitted, and the sample inlet 311 and the pin 214 are concentrically set.

[0046] A gasket 218 is filled between the rotating disk 215 and the mounting base 1, and the limiting stop pin 212 is located on the rotation path of the rotating disk 215.

[0047] The rotating disk 215 has a rotating disk positioning hole 2151. When the rotating disk positioning hole 2151 is moved to the position directly above the mounting base positioning hole 213, the rotating disk 215 and the mounting base 1 can be locked by inserting the positioning pin 2152 into the rotating disk positioning hole 2151 and the mounting base positioning hole 213 in sequence.

[0048] Example 2

[0049] from Figure 5 As can be seen, the belt conveyor head wheel material flow sampling device of this embodiment adopts an electric drive mechanism 22; the electric drive mechanism 22 includes a motor 221; the motor 221 is mounted on the front wall 4 of the belt transfer funnel through the mounting base 1; the output end of the motor 221 is connected to a rotating shaft 222, and the bottom end of the rotating shaft 222 is connected to the sample delivery tube 31.

[0050] In this embodiment, the sampling operation is powered by motor 221, and its working principle is the same as that of the manual sampling device, which will not be described in detail here.

[0051] Example 3

[0052] from Figure 1-3 As can be seen, the method for sampling material flow from a belt conveyor head pulley in this embodiment is a manual sampling operation method:

[0053] When not in operation; the sampling hopper 32 rotates to one side of the inner side of the belt conveyor transfer funnel, the rotating handle 216 rests against the side of the limit stop pin 212, and the positioning pin 2152 is inserted into the positioning hole 2151 of the rotating disk and the positioning hole 213 of the mounting base to ensure that the sampling hopper 32 is fixed in position and does not come into contact with the material flow.

[0054] During sampling, the handle 219 is inserted into the rotating handle 216, the positioning pin 2152 is pulled out, and the handle 219 is pushed to rotate. The sampling hopper 32 sweeps across the material flow, and the material in the cross-section of the material flow will enter the sampling hopper 32 and flow into the sample storage bucket 33 through the sample delivery pipe 31. The handle 219 drives the rotating disk 215 to rotate to the other side, where it is stopped by the limiting stop pin 212. At this time, the positioning pin 2152 is inserted into the positioning hole 2151 of the rotating disk and the positioning hole 213 of the mounting base. The handle 219 is removed, and the sampling operation is completed.

[0055] This invention employs a sampling hopper 32 that sweeps across the cross-section of the material flow, collecting samples that accurately reflect the overall characteristics of the material. This results in more representative and authentic sampling, effectively ensuring sampling accuracy. The sampling mechanism 3 is driven by a manual drive mechanism 21 or an electric drive mechanism 22 to swing around the centerline of the sample inlet 311. The manual drive mechanism 21 is simple in structure, quick to operate, requires low equipment investment, reduces the labor intensity of sampling personnel, and is safe and reliable. The sampling speed can be manually controlled to meet sampling volume requirements, ensuring sampling accuracy, while also saving on subsequent maintenance and electricity costs. Based on the lever principle, it effectively reduces labor intensity, allowing sampling personnel to avoid approaching the running conveyor belt and materials during sampling, eliminating safety hazards such as being caught in the belt or injured by falling materials.

[0056] When the sampling device is powered by a motor, it is composed of a programmable logic controller (IPC) and a text display (TD400) to achieve manual / automatic control. Automatic control can automatically sample according to the set time interval, and it can also be remotely controlled through the central control room, avoiding manual intervention, realizing remote intelligent control, and improving work efficiency.

[0057] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
