Description

Technical Field

[0001] This utility model belongs to the field of sampling technology, specifically relating to a material sampling device. Background Technology

[0002] In the production workshop, it is necessary to sample incoming materials. In the existing technology, sampling is usually done manually, which increases the workload of workers and the operation time. At the same time, the conveyor belt is an unmanned operation area, and personnel cannot stay there for a long time. Furthermore, direct manual sampling poses certain safety hazards, which makes it impossible for operators to complete the required uninterrupted sampling work and to collect samples evenly and continuously on the conveyor belt in a timely manner. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model provides a material sampling device that solves the problem of continuous and uniform sampling of incoming materials on the conveyor belt, reduces the workload of workers, and reduces the operation time.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides a material sampling device, including a first mounting frame and a second mounting frame respectively disposed on both sides of a conveyor belt. A mounting horizontal shaft is fixedly mounted on the first mounting frame, with one end extending above the conveyor belt. A rotating sampling frame is rotatably connected to the end of the mounting horizontal shaft above the conveyor belt. A drive mechanism for controlling the rotation of the rotating sampling frame is provided on the first mounting frame. At least two sampling chutes extend outward from the side of the rotating sampling frame. One end of each sampling chute communicates with the internal space of the rotating sampling frame, and a sampling spoon is provided at the other end of each sampling chute for sampling material on the belt. A sampling tube is mounted on the second mounting frame, having an inlet end and an outlet end. The inlet end extends obliquely upward into the rotating sampling frame and has a receiving port for receiving material flowing out from the sampling chutes. The outlet end extends obliquely downward, and a sampling container is disposed below the outlet end.

[0006] As a further improvement to the above solution, the driving mechanism includes a drive motor mounted on a first mounting frame. The output end of the drive motor is connected to a first transmission wheel via a rotating shaft. The first transmission wheel is connected to a second transmission wheel via a transmission belt. The second transmission wheel is fixedly mounted at the rear of the rotating sampling frame.

[0007] As a further improvement to the above solution, the inner side of the rotating sampling frame is provided with a guide trough for each sampling chute, and the guide trough is used to transfer the material from the sampling chute to the receiving port.

[0008] As a further improvement to the above solution, the side wall of the rotating sampling frame is provided with discharge ports corresponding to the number of guide troughs.

[0009] As a further improvement to the above solution, the discharge port and the guide trough are spaced apart.

[0010] As a further improvement to the above solution, the sampling chute body and the sampling spoon are detachably and fixedly connected.

[0011] As a further improvement to the above solution, the sampling spoon is slidably connected to the lower end of the sampling chute, and a fastening adjustment component is provided between the sampling spoon and the sampling chute.

[0012] As a further improvement to the above solution, the fastening adjustment component is a fastening bolt installed on the side wall of the sampling chute.

[0013] As a further improvement to the above solution, an anti-slip mechanism is also provided between the sampling spoon and the sampling chute to prevent the sampling spoon from slipping off.

[0014] As a further improvement to the above solution, the anti-detachment mechanism includes a blocking horizontal plate fixedly installed in the sampling chute body, and an inverted L-shaped blocking rod rotatably connected to the upper end of the sampling spoon.

[0015] The beneficial effects of this utility model are:

[0016] Compared with the prior art, this utility model uses a drive mechanism to drive the rotating sampling frame and sampling chute to rotate, thereby controlling the sampling spoon to scoop up the material on the conveyor belt. The material scooped up by the sampling spoon can flow into the internal space of the sampling frame under the action of gravity as the sampling chute rotates. The material is collected through the sampling pipe with a receiving port and guided into the sampling container, realizing uniform and uninterrupted sampling of the material during transportation, improving sampling efficiency, improving sampling safety, reducing the operation time of the staff, and reducing the workload of the staff.

[0025] like Figures 1 to 6 As shown, this utility model provides a material sampling device, including a first mounting frame 2 and a second mounting frame 3 respectively disposed on both sides of a conveyor belt 1. A mounting horizontal shaft 4 is fixedly disposed on the first mounting frame 2, with one end of the mounting horizontal shaft 4 extending above the conveyor belt 1. A rotating sampling frame 5 is rotatably connected to the end of the mounting horizontal shaft 4 located above the conveyor belt 1. A drive mechanism for controlling the rotation of the rotating sampling frame 5 is disposed on the first mounting frame 2. At least two sampling chutes are provided on the side of the rotating sampling frame 5 extending outward. The sampling chute body 6 has one end connected to the internal space of the rotating sampling frame 5, and the other end of the sampling chute body 6 is provided with a sampling spoon 7, which is used to sample the material on the belt. The second mounting frame 3 is equipped with a sample outlet tube 8, which has an inlet end and a outlet end. The inlet end extends obliquely upward into the rotating sampling frame 5, and the inlet end is provided with a receiving port 801 for receiving the material drained from the sampling chute body 6. The outlet end extends obliquely downward, and a sampling container 9 is provided below the outlet end.

[0026] Specifically, in this embodiment, the sampling device is set at the conveyor belt in the homogenization chamber. The material being conveyed is quartz sand (silica sand), with a particle size range of 100 micrometers to 710 micrometers, less than 5% below 100 micrometers, a moisture content range of 3% to 12%, and a pH value of 3 to 7.

[0027] Furthermore, the mounting horizontal axis 4 can be fixedly connected to the first mounting frame 2 by welding or other means, or can be detachably fixedly connected to the first mounting frame 2 by clamps or other mechanisms.

[0028] Furthermore, the end of the horizontal shaft 4 located on the conveyor belt 1 can pass through the rotating sampling frame 5 and be fixedly connected to the sample outlet tube 8, for example, by welding or bolting. The fixed connection between the horizontal shaft 4 and the sample outlet tube 8 can improve the overall stability of the structure.

[0029] Specifically, in this embodiment, the number of sampling chute bodies 6 is preferably 2 to 6, and the actual number can be set according to the requirements.

[0030] Specifically, the drive mechanism includes a drive motor 10 mounted on the first mounting frame 2. The output end of the drive motor 10 is connected to a first transmission wheel 12 via a rotating shaft 11. The first transmission wheel 12 is connected to a second transmission wheel 14 via a transmission belt 13. The second transmission wheel 14 is fixedly mounted at the rear of the rotating sampling frame 5.

[0031] Furthermore, the rotating sampling frame 5 is mounted on the mounting horizontal shaft 4 and will only rotate around the mounting horizontal shaft 4 under the drive of the drive motor 10. Front and rear limit components can be set on the mounting horizontal shaft 4 to prevent the rotating sampling frame 5 from displacing in the horizontal direction.

[0032] Furthermore, a guide trough 15 is provided on the inner side of the rotating sampling frame 5 for each sampling chute 6. The guide trough 15 is used to transfer the material from the sampling chute 6 to the receiving port 801. The guide trough 15 is a transition area for material conveying between the sampling chute 6 and the receiving port 801, which enables the material to be conveyed into and out of the sampling pipe 8 in a concentrated manner, avoiding material spillage.

[0033] Furthermore, the sampling spoon 7, the sampling chute 6, and the sample outlet tube 8 can be made of stainless steel.

[0034] Furthermore, the side wall of the rotating sampling frame 5 is provided with a corresponding number of discharge ports 501 for the material guide troughs 15. The discharge ports 501 are provided so that during rotation, the materials scattered in the rotating sampling frame 5 or suspended and deposited in the rotating sampling frame 5 fall onto the belt, avoiding sample accumulation.

[0035] Specifically, the discharge port 501 and the guide trough 15 are spaced apart.

[0036] Furthermore, the sampling chute 6 and the sampling spoon 7 are detachably and fixedly connected.

[0037] Specifically, the sampling spoon 7 is slidably connected to the lower end of the sampling chute body 6, and a fastening adjustment component 16 is provided between the sampling spoon 7 and the sampling chute body 6. The sampling spoon 7 can be replaced after it is worn out, and the detachable connection between the sampling spoon 7 and the sampling chute body 6 allows the sampling height of the sampling spoon 7 to be adjusted.

[0038] Specifically, the fastening adjustment component 16 is a fastening bolt installed on the side wall of the sampling chute body 6.

[0039] Furthermore, an anti-slip mechanism is provided between the sampling spoon 7 and the sampling chute body 6 to prevent the sampling spoon 7 from slipping off. The anti-slip mechanism can prevent the sampling spoon 7 from accidentally falling onto the belt when changing the sampling spoon 7 or adjusting the sampling height.

[0040] Specifically, the anti-detachment mechanism includes a blocking horizontal plate 17 fixedly installed on the sampling chute body 6, and an inverted L-shaped blocking rod 18 rotatably connected to the upper end of the sampling spoon 7.

[0041] Specifically, the inverted L-shaped blocking rod 18 is threadedly connected to the sampling spoon 7. The inverted L-shaped blocking rod 18 has a horizontal section and a vertical section. The vertical section is threadedly connected to the sampling spoon 7, and the horizontal section is located above the blocking plate 17 after being rotated out.
