Description

Technical Field

[0001] This application relates to the technical field of coal sampling equipment, and particularly to an automatic raw coal sampling device. Background Art

[0002] As the main fuel in the industrial production process, raw coal is widely used, and various factories have a high demand for it. To ensure the quality of raw coal, sampling and testing are required when it enters the factory.

[0003] However, since the incoming raw coal may come from different mines, and the quality of the raw coal produced by different mines varies, the currently used sampling devices usually perform single sampling, that is, the position of the sampler is fixed, and only one sampling channel is provided. When changing the coal sample, due to the single sampling channel, this sampling method is prone to sample mixing, thus affecting the test results. Summary of the Utility Model

[0004] To solve or partially solve the problems existing in the related technologies, this application provides an automatic raw coal sampling device, which can adjust the sampling position of the sampling shovel and correspondingly set multiple sample collection mechanisms, thereby avoiding the situation of sample mixing and ensuring the accuracy of the test results.

[0005] This application provides an automatic raw coal sampling device, including a frame, a hydraulic push rod, a traveling trolley, a sampling shovel, and a sample collection mechanism. The traveling trolley is slidably installed on the frame, and a hydraulic push rod for driving the traveling trolley is provided on the frame. A sampling shovel corresponding to a trough belt conveyor is rotatably installed on the traveling trolley, and multiple groups of sample collection mechanisms for collecting the sampled samples are also provided on both sides of the frame.

[0006] Optionally, in some embodiments, two brackets are symmetrically provided on the frame. The traveling trolley is slidably connected between the two brackets, and a cross beam is fixedly provided between the two brackets. The hydraulic push rod is installed on the cross beam, and the end of the hydraulic push rod is connected to the traveling trolley.

[0007] Optionally, in some embodiments, the traveling trolley includes a vehicle frame, a pulley, and a slide rail. Slide rails are symmetrically provided on the two brackets, and the vehicle frame is slidably connected to the slide rails through the pulley, so that the vehicle frame can be translated along the slide rails under the action of the hydraulic push rod.

[0008] Optionally, in some embodiments, a speed reducer is fixedly installed at the middle position of the top of the vehicle frame, and a sampling shovel is fixedly connected to the output shaft of the speed reducer. By controlling the forward and reverse rotation of the speed reducer, the left or right swing of the sampling shovel can be controlled.

[0009] Optionally, in some embodiments, the sample collection mechanism includes a sampling tube, a side frame, a baffle, and a cylinder. The sampling tube is a tubular structure with a sampling port at its top. A side frame is provided at the sampling port, and a baffle is slidably connected inside the side frame. The opening and closing of the sampling port can be controlled by sliding the baffle, and a cylinder for driving the baffle is also installed on the side frame.

[0010] The technical solution provided by this application may include the following beneficial effects:

[0011] In this application, multiple groups of sample collection mechanisms are provided on the frame, and the position of the walking trolley on the frame is changed by the hydraulic push rod, thereby adjusting the position of the sampling shovel. When changing the sample of raw coal, only the sampling position needs to be changed, and the coal samples can be collected by the sample collection mechanisms at different positions, avoiding sample mixing and ensuring the accuracy of the test results.

[0025] See Figure 1, A raw coal automatic sampling device, comprising a frame 1, a hydraulic push rod 4, a traveling trolley 5, a sampling shovel 7, and a sample collection mechanism 8. The frame 1 is fixedly installed on the ground. A trough belt conveyor 9 passes through the bottom of the frame 1. On the left and right sides of the frame 1, brackets 2 are respectively arranged along the running direction of the trough belt conveyor 9. The two brackets 2 are symmetrical to each other, and a traveling trolley 5 is slidably installed between the two brackets 2. A cross beam 3 is also fixedly arranged between the two brackets 2. The hydraulic push rod 4 is installed on the cross beam 3 through a support 31, and the end of the hydraulic push rod 4 is connected to the traveling trolley 5. By controlling the extension or shortening of the hydraulic push rod 4, the position of the traveling trolley 5 on the bracket 2 can be changed; further, a sampling shovel 7 corresponding to the trough belt conveyor 9 is rotatably installed on the traveling trolley 5. Four groups of sample collection mechanisms 8 for collecting the sampled samples are also arranged on the left and right sides of the frame 1. By controlling the left and right rotation of the sampling shovel 7, the raw coal on the trough belt conveyor 9 can be pushed into the sample collection mechanism 8, thereby realizing automatic sampling. When the coal sample is changed, by controlling the hydraulic push rod 4 to change the position of the traveling trolley 5, the sampling shovel 7 corresponds to different sample collection mechanisms 8, so as to avoid the situation of sample mixing, thereby ensuring the accuracy of detection.

[0026] In one embodiment, referring to Figure 2 、 3 , the traveling trolley 5 includes a vehicle frame 51, pulleys 52, and slide rails 53. The slide rails 53 are fixedly arranged on the top of the bracket 2, and the two slide rails 53 are symmetrical to each other. Pulleys 52 are rotatably installed on the left and right sides of the bottom of the vehicle frame 51. The pulleys 52 are slidably connected to the slide rails 53, so that the vehicle frame 51 can be translated along the slide rails 53 under the action of the hydraulic push rod 4.

[0027] In one embodiment, referring to Figure 2 、 4 , a speed reducer 6 is fixedly installed at the middle position of the top of the vehicle frame 51. A sampling shovel 7 is fixedly connected to the output shaft of the speed reducer 6. By controlling the forward and reverse rotation of the speed reducer 6, the left or right swing of the sampling shovel 7 can be controlled, so as to push the raw coal on the trough belt conveyor 9 into the corresponding sample collection mechanism 8 for sampling.

[0028] In one embodiment, referring to Figure 5, the sample collection mechanism 8 includes a sampling tube 81, side frames 82, baffles 83, and a cylinder 84. The sampling tube 81 is a tubular structure, its bottom is connected to the sample collection box, and its top is provided with a sampling port 85. A side frame 82 is fixedly arranged at the sampling port 85. A baffle 83 is slidably connected inside the side frame 82. The opening and closing of the sampling port 85 can be controlled by sliding the baffle 83. A cylinder 84 is also fixedly installed on the side of the side frame 82. The end of the cylinder 84 is connected to the baffle 83. The movement of the baffle 83 can be automatically controlled by the cylinder 84, thereby realizing the automatic opening and closing of the sampling port 85. When in use, when sampling is not being carried out, all sampling ports 85 are in the closed state, preventing the raw coal on the troughed belt conveyor 9 from accidentally falling into the sampling port 85 and avoiding sample mixing. When sampling, only the baffle 83 at the corresponding sampling port 85 is controlled to open, thereby preventing the coal sample from falling into other sampling ports 85 and ensuring the accuracy of sampling.

[0029] Based on the above embodiments, since after each sampling, there will be some coal samples remaining on the sampling shovel 7, and during the sampling process, the coal samples may spill on each baffle 83. At this time, after changing the sample, when sampling again, it is easy to cause sample mixing. Therefore, nozzles corresponding to the sampling shovel 7 and each sampling port 85 can be installed on the frame 1. The nozzles are connected to the jetting equipment. After each sampling is completed, the sampling shovel 7 and each sampling port 85 are jet-cleaned through the nozzles, thereby ensuring the accuracy of subsequent sampling and avoiding sample mixing.

[0030] Specific working process:

[0031] When sampling, the sampling port 85 of one of the sampling tubes 81 is opened by controlling the cylinder 84. The walking trolley 5 is moved by controlling the hydraulic push rod 4 so that the sampling shovel 7 is aligned with the opened sampling port 85. As the troughed belt conveyor 9 operates, the raw coal passes under the sampling shovel 7. The speed reducer 6 is started to make the sampling shovel swing, thereby pushing some of the raw coal to the sampling port 85. The raw coal falls into the sample collection box through the sampling port 85, and the sampling is completed;

[0032] After sampling is completed, the sampling port 85 is closed, and the sampling shovel 7 and each sampling port 85 are jet-cleaned. When the coal sample is changed, another sample collection mechanism 8 is used for sampling, and the above steps are repeated.

[0033] Finally, it should also be noted that in this article, relationships such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
