[0002] After limestone is calcined into lime, samples are usually taken from the conveyor belt for testing. Sampling on a running belt is very likely to cause personal injury accidents. If the belt is stopped before sampling, when it is restarted after sampling, it is considered to be started under load because there is lime on the belt, which will seriously affect the service life of the motor. In addition, manual sampling will also cause dust pollution, affecting the health of the sampling personnel.

[0003] Therefore, in order to carry out sampling more reasonably and safely and avoid the occurrence of the above situation, a sampling device is urgently needed. Utility Model Content

[0027] The following further describes the specific technical solutions of the present invention with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to their rights.

[0028] Example 1, reference Figure 1-4 An online lime sampler is arranged above a lime belt conveyor 1 and includes a sealing cover 2 which is arranged on the lime belt conveyor 1. The shape and specifications of the sealing cover 2 can be customized according to the use requirements. The design purpose is only to accommodate the sampling mechanism. The sampling mechanism is installed in the sealing cover 2. The sampler is equipped with the sealing cover 2. The sealing cover 2 can prevent lime dust from splashing to the outside and causing environmental pollution, and can play a certain safety protection role when the scraper moves.

[0029] In order for the sampling staff to observe the internal situation of the sealing cover 2, an observation port 15 may be provided in the middle of the sealing cover 2;

[0030] A lime sample feeding trough 3 is fixedly provided at the bottom of the sealing cover 2. The lime sample feeding trough 3 is formed into a roughly square trough structure, which is used to receive the lime sample moved by the sampling mechanism. When the lime sample is moved into the lime sample feeding trough 3 by the scraper, it can further fall into the collecting trough 4 below the lime sample feeding trough 3, thereby facilitating the collection of the lime sample.

[0031] The sampling mechanism includes a rotary power mechanism and a scraper assembly. The rotary power mechanism is installed at the center of the inner wall of the sealing cover 2. One end of the scraper assembly is connected to the rotary power mechanism and is provided with a swinging rotational force by the rotary power mechanism, thereby moving the lime on the lime belt conveyor 1 below the sampling mechanism into the lime sample chute 3. The entire sampling process does not require the sampling staff to arrive at the site for operation. It is only necessary to pick up the lime sample in the lime sample chute 3, which provides a certain degree of operational safety for the sampling staff.

[0032] The rotary power mechanism includes a drive motor 5, a reducer 6, a coupling 7 and a main shaft 8 connected in sequence. The drive motor 5 and the reducer 6 are of existing technology and their specifications and models can be selected according to the use requirements. A bearing seat 9 mounted on the inner wall of the sealing cover 2 is further provided at the other end of the main shaft 8. The axis of the power output end of the drive motor 5, the axis of the coupling 7 and the axis of the main shaft 8 are collinear.

[0033] The scraper assembly includes a fixed plate 10, a scraper lining 11 and a scraper 12. The fixed plates 10 are provided in a pair and are located on both sides of the main shaft 8. The fixed plates 10 are formed into a substantially square plate-shaped structure. The pair of fixed plates 10 are clamped on the outer peripheral surface of the main shaft 8 by bolt fasteners. One end of the scraper lining 11 is fixedly connected to the bolt fastener installed on the fixed plate 10, and the other end is fixedly connected to the scraper 12. The scraper lining 11 and the scraper 12 are both formed into a substantially square plate-shaped structure.

[0034] The end of the main shaft 8 extends out of the sealing cover 2, and a photoelectric tube 14 is installed on the outer wall of the sealing cover 2 above the main shaft 8. The photoelectric tube 14 is a prior art and its specifications and models can be selected according to the use requirements. The outer peripheral surface of the end of the main shaft 8 away from the rotating power mechanism is a line having a mating surface 13 that fits with the fixed plate 10. For details, please refer to the attached Figure 4 ;

[0035] The shortest distance between the end of the scraper 12 away from the scraper liner 11 and the belt of the lime belt conveyor 1 is 5mm~10mm;

[0036] The height difference between the belt center and the side edge of the lime belt conveyor 1 is H1, the horizontal distance between the belt center and the side edge of the lime belt conveyor 1 is B1, and the shortest distance between the axis of the main shaft 8 and the belt of the lime belt conveyor 1 is H, and H = (H1² + B1²) / 2H1 + (5~10);

[0037] The speed of the scraper 12 is 15r~25r / min;

[0038] The center of the end face of the main shaft 8 is taken as the center of the circle, the edge of the top surface of the belt of the lime belt conveyor 1 is taken as the arc, the central angle of the arc is α, and the angle between the initial position and the final position of the scraper 12 when it swings is β, and β=α+(5°~15°);

[0039] The scraper 12 has a width of 300 mm and a height of 100 mm to 200 mm.

[0040] When the online lime sampler is in use, when sampling is required, the drive motor 5 is driven. At this time, the drive motor 5 cooperates with the reducer 6 to drive and drive the main shaft 8 to rotate. The scraper liner 11 fixed on the rotating shaft drives the scraper 12 to rotate a certain angle. During the swinging process, the lime on the lime belt conveyor 1 is moved into the lime sample chute 3 in the sealing cover 2, and the lime sample chute 3 falls into the collecting trough 4 below by its own weight, completing the sampling operation of the lime sample. After the sampling is completed, the scraper 12 rotates to the initial position, completing a complete sampling cycle.
