Description

Technical Field

[0001] The utility model belongs to the technical field of coal sampling and preparation, and in particular relates to an intelligent weighing device for coal sampling and preparation. Background Art

[0002] In the process of coal sampling and preparation, sampling and weighing are carried out to obtain the quality information of coal samples in order to carry out subsequent chemical analysis, physical property testing and other experiments. Sampling and weighing can determine the quality of each sample and the number of samples required for subsequent experiments. At the same time, sampling and weighing can also ensure the accuracy and repeatability of experimental results. After the sampler samples the coal, it introduces it into the sampling tank and then weighs and records the sample.

[0003] In the current sampling and weighing process of coal sampling, there is insufficient continuity between sampling and subsequent weighing. After the samples are collected, they often need to be weighed manually and the relevant data must be recorded item by item. This link is not only time-consuming and labor-intensive, but also prone to human errors, thereby greatly reducing the efficiency and accuracy of the overall weighing work. Utility Model Content

[0014] Preferably, the intelligent weighing device is arranged between two supporting frames, and the conveyor is electrically connected to the control panel.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) By setting a conveyor, a toggle block, an intelligent weighing device, a sampling tube, a limit plate and a spring, the conveyor is started, driving the toggle block to move, and the toggle block drives the sampling tank to move in the limit device. When the sampling tank moves to the bottom of the sampling tube, the sampler introduces the collected sample into the sampling tank through the sampling tube, weighs it using the intelligent weighing device, and records it through the control panel. Then, the toggle block is used to push the sampling tank to move. During the movement, the sampling tank pushes the limit plate, so that the limit plate rotates in the groove and pulls the spring to extend. After the sampling tank is moved out, the limit plate is reset by the spring's resilience, thereby utilizing the toggle of the conveyor and the toggle block to improve the continuity of weighing, and intelligent weighing and recording are performed, thereby reducing human errors and improving the efficiency and accuracy of weighing.

[0017] (2) By setting a base, a limiting rod, a movable column and a supporting frame, the sampling tank is placed on the top of the movable column. When the toggle block pushes the sampling tank to move, the movable column rotates due to friction, thereby reducing friction and improving the flexibility of the sampling tank's displacement. The limiting rods on both sides are used to limit the sampling tank, thereby preventing the sampling tank from deviating from its position and improving the stability of the sampling tank during displacement.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 - Figure 4 As shown, a coal sampling intelligent weighing device comprises:

[0026] Base 1;

[0027] Support plates 2 are fixedly connected to both sides of the top of the base 1, and the tops of the two support plates 2 are fixedly connected to a limiting device 3, and one end of the limiting device 3 is fixedly connected to a sample injection structure 5;

[0028] The sample injection structure 5 includes a connecting plate 51, a groove 52, a limiting plate 53, a connecting rod 54, a spring 55, a fixing plate 56 and a sample injection tube 57. The groove 52 is provided at one end of the connecting plate 51. The limiting plate 53 is movably connected between the inner walls of both sides of the groove 52. Two connecting rods 54 are provided, and two sample injection tubes 57 are fixedly connected to one end of the limiting plate 53 and one end of the connecting plate 51, respectively. The spring 55 is fixedly connected between the two connecting rods 54. The connecting plate 51 is fixedly connected to the base 1.

[0029] The limiting device 3 includes a base 31, a limiting rod 33 and a support frame 34. A plurality of support columns 32 are fixedly connected at equal distances on both sides of the top of the base 31. Two limiting rods 33 and two support frames 34 are provided, and the two limiting rods 33 are respectively fixedly connected to the tops of the plurality of support columns 32 on both sides. The two support frames 34 are fixedly connected between the two limiting rods 33. A plurality of movable columns 35 are movably interspersed and connected at equal distances in the support frame 34. A plurality of through holes 36 are opened at the top of the base 31. The base 31 is fixedly connected to the tops of the two support plates 2.

[0030] An intelligent weighing device 4 is installed on the top of the base 1, and one end of the limiting device 3 is fixedly connected to a control panel 9, which is electrically connected to the intelligent weighing device 4. One end of the base 1 is fixedly connected to two support frames 6, and the tops of the support frames 6 are commonly fixedly connected to a conveyor 7. A plurality of toggle blocks 8 are fixedly connected at equal distances in the conveyor 7, and a sampling tank 10 is movably and interlacedly connected in the limiting device 3.

[0031] Depend on Figure 1 and Figure 3 It can be seen that the fixed plate 56 is fixedly connected to the top of the connecting plate 51, the sampling tube 57 is fixedly inserted and connected to the top of the fixed plate 56, and the lower part of the sampling tube 57 passes through the bottom end of the fixed plate 56 and extends to the bottom thereof.

[0032] As can be seen from the above, the conveyor 7 is started, driving the toggle block 8 fixedly connected to it to move. When the toggle block 8 is displaced, it drives the sampling tank 10 to move in the limiting device 3. The sampling tank 10 moves to the bottom of the sampling tube 57. The sampler introduces the collected sample into the sampling tube 57. The sampling tube 57 introduces the sample into the sampling tank 10, weighs it through the intelligent weighing device 4, and records it through the control panel 9. Then the sampling tank 10 is pushed to move by the toggle block 8. During the movement, the sampling tank 10 pushes the limiting plate 53.

[0037] As can be seen from the above, the sampling tank 10 is placed on the top of the movable column 35. When the toggle block 8 pushes the sampling tank 10 to move, the movable column 35 rotates due to friction, thereby reducing friction and improving the flexibility of the displacement of the sampling tank 10. The sampling tank 10 is limited by the limiting rods 33 on both sides to prevent the sampling tank 10 from deviating from the position, thereby improving the stability of the sampling tank 10 during displacement. One side of the support frame 34 is set to an inclined shape, thereby facilitating the sampling tank 10 to move into and out of the upper end of the smart weighing device 4.
