Description

Technical Field

[0001] The invention belongs to the technical field of coal selectivity, and in particular relates to a coal particle sampling device capable of movable interception sampling. Background Art

[0002] Coal is known as black gold and food for industry. It has been one of the main energy sources used by the human world since the 18th century. Coal selectivity is the main basis for coal preparation technology research and coal preparation plant design. Therefore, the purpose of studying coal selectivity is to reasonably select coal preparation methods, coal preparation technology and determine product structure, so as to rationally utilize coal resources. In order to accurately evaluate coal selectivity, coal preparation workers at home and abroad have been continuously studying selectivity assessment methods.

[0003] Regarding the selectivity of coal, it is first screened through the feed port and then conveyed by a belt conveyor. X-rays, visible light cameras, and depth cameras are used to collect data in the belt conveyor area to obtain the shape profile and transmittance data of each coal particle. Sampling is then carried out. For sampling of coal particles at the end of the conveyor belt, a sampling cup is often placed at the end of the conveyor belt, and the coal particles fall into the sampling cup. After sampling, the sample needs to fall into a storage box. The entire sampling and discharging process requires more electric structures, which invisibly increases the cost of equipment use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-9 As shown, the present invention is a coal particle sampling device for movable interception and sampling, including: a support column 1, a support cross plate 2 fixedly arranged at the top of the support column 1, a collection support plate 37 fixedly arranged on one side of the support column 1, and a plurality of groups of sampling collection bins 38 horizontally arranged at intervals on the top of the collection support plate 37; the whole device is placed at the end of the conveyor belt, samples the coal particles and then puts them into the sampling collection bins 38 for collection. An adjustment base 7 is arranged on the top of the support cross plate 2, so that the adjustment base 7 can move above the support cross plate 2 to adjust the position. In order to improve the movement stability of the adjustment base 7, horizontally arranged side bins 3 are fixedly arranged at both ends of the top of the support column 1. Limit slide rods 8 slidably penetrating through the adjustment base 7 are fixedly arranged on the opposite sides of two groups of side bins 3. A driving motor 1 is fixedly arranged on the side of one group of side bins 3, so that the output end of the driving motor 1 extends into the side bin 3, and a winding roller 5 is arranged in the side bin 3. Synchronous belts 6 are wound between two groups of synchronous belts 6. The winding roller 5 rotates by the drive of the driving motor 1, and then the synchronous belts 6 perform a circumferential movement. The top of the synchronous belts 6 is fixedly connected to the adjustment base 7, that is, when the synchronous belts 6 move, the adjustment base 7 will be driven to adjust the position above the support cross plate 2. A displacement cross plate 39 is fixedly arranged on the top of the adjustment base 7, and a top tooth plate part 40 is fixedly arranged at the center of the displacement cross plate 39. At the same time, a functional base 9 is slidably connected to the top of the displacement cross plate 39, so that the functional base 9 can slide along the top of the displacement cross plate 39. A driving member is arranged at the center of the displacement cross plate 39 and is composed of a motor and a tooth cylinder meshed with the top tooth plate part 40. The tooth cylinder rotates by the drive of the motor, so that the tooth cylinder moves radially along the track of the top tooth plate part 40, and thus the movement of the functional base 9 can be realized.

[0039] At the center of the upper end of the functional base 9, a second driving motor 10 is fixedly installed. A rotating rod portion 11 is connected to the output end of the second driving motor 10. At the top of the rotating rod portion 11, a rotating ejector rod 12 is fixedly installed. A ejector rod sleeve column 13 is fixedly installed at the front end of the rotating ejector rod 12. Plug rod portions 14 are installed at both ends of the ejector rod sleeve column 13. A sampling railing 15 is fixedly installed at the bent portion at the front end of the plug rod portion 14. A railing slot 16 is formed on the surface of the sampling railing 15. An inserting rotating rod 17 is assembled in the slot of the railing slot 16. The length of the inserting rotating rod 17 is greater than the width of the slot of the railing slot 16, so that one end of the inserting rotating rod 17 passes through the railing slot 16 and extends out to one side of the sampling railing 15. The entire inserting rotating rod 17 rotates freely along the sampling railing 15. A sampling stop block 18 in the shape of a plate structure is fixedly installed on the outer wall of the inserting rotating rod 17 on the inner side of the slot of the railing slot 16. The distance between the two groups of sampling railings 15 during actual use is greater than the distance between coal particles. The two groups of sampling stop blocks 18 are inclined towards the gap between the two groups of sampling railings 15. Therefore, the distance between the two groups of sampling stop blocks 18 is smaller than the size of coal particles. As a result, coal particles will be retained at the position between the two groups of sampling railings 15 and between the two groups of sampling stop blocks 18. In this way, a group of coal particles can be temporarily stored without affecting other coal particles from freely falling from both sides of the sampling railing 15, avoiding the situation of coal particle accumulation again. A protective side plate 20 extending towards the gap between the two groups of sampling railings 15 is fixedly installed on the end face of the sampling stop block 18 away from the plug rod portion 14. The plug rod portion 14 and the sampling railing 15 are combined into a U-shaped structure. The coal particles sampled inside the sampling railing 15 need to be rotated to the upper part of the other sampling collection bin 38 by the drive of the second driving motor 10 and the rotating rod portion 11. Since centrifugal force will be generated by the coal particles during the rotation process, through the limitation of the two groups of protective side plates 20, the coal particles can be prevented from being thrown out, improving the stability of the coal particles during the transfer process and the sampling stability of the coal particles.

[0040] A side convex plate portion 21 is fixedly provided on the outer wall of the exposed part of the inserted rotating rod 17, wherein an arc-shaped spacing distribution of insertion hole portions 22 is opened at the side end of the sampling railing 15, and the insertion rod 23 can be inserted into the groove of each group of the insertion hole portions 22, and a spring portion 24 is installed between the insertion rod 23 and the side convex plate portion 21, so that the top of the spring portion 24 is connected to the side convex plate portion 21 by clamping, and a ring that can be sleeved on the outside of the insertion rod 23 is provided at the other end of the spring portion 24, thereby completing the connection between the side convex plate portion 21 and the insertion rod 23 through the spring portion 24, and the elasticity of the spring portion 24 tightens the inserted rotating rod 17 and the sampling stopper 18 to prevent the sampling stopper 18 from clamping coal particles and falling. A toggle plate 19 is fixedly disposed on the top side wall of the sampling stopper 18, and a rotating functional disk 36 of a disc-shaped structure is also fixedly disposed on the outer wall of the rotating rod portion 11, wherein a triggering protrusion portion 30 protruding downward is fixedly disposed at the bottom of the rotating functional disk 36, and an extended base plate 25 is fixedly disposed on one side of the base of the driving motor 10, so that an upwardly extending top support plate 26 is fixedly disposed at the end of the extended base plate 25, and a lever portion 27 is rotatably connected between the two sets of top support plates 26 distributed at intervals, wherein a triggering portion 22 is disposed at one end of the lever portion 27 9, the bottom of the lever portion 27 is connected to a spring portion 28, and the other end of the spring portion 28 is connected to the upper end of the extended base plate 25. Under the elastic tension of the spring portion 28, the top of the trigger portion 29 is always attached to the bottom of the rotating function disk 36, and the rotating function disk 36 rotates with the rotation of the rotating rod portion 11, and the triggering protrusion portion 30 is located directly below the rotating top rod 12. When the rotating top rod 12 rotates to one side of the lever portion 27, the top of the trigger portion 29 is moved along the inclined direction of the triggering protrusion portion 30. The surface of the lever portion 27 finally abuts against the surface of the triggering protrusion 30, that is, in this position, the inclination angle of the lever portion 27 changes, so that the horizontal height of one side of the triggering portion 29 is lower, and the horizontal height of the other end of the lever portion 27 is higher, and a lever front sleeve 31 is fixedly arranged at the end of the lever portion 27 at a higher position, wherein the two ends of the lever front sleeve 31 are connected to side sliding rods 32, and a triggering push rod 33 is fixedly arranged at the end of the side sliding rod 32, and the spacing between the two sets of triggering push rods 33 is equal to the spacing between the two sets of toggle pieces 19, that is, when the rotation When the rotary ejector rod 12 rotates to one side of the lever portion 27, the trigger ejector rod 33 moves upward and can abut against the bottom surface of the toggle plate 19. It is worth noting that the toggle plate 19 has a large area, and the upward movement of the trigger ejector rod 33 will not separate from the surface of the toggle plate 19. By triggering the upward movement of the ejector rod 33, the toggle plate 19 can drive the sampling block 18 to rotate, thereby causing the two groups of sampling blocks 18 to expand outward, allowing the sample to fall freely between the two groups of sampling blocks 18 and fall into the sampling collection chamber 38.The connection mode of the side sliding rod 32 and the front sleeve 31 of the lever is the same as that of the insertion rod part 14 and the top rod sleeve column 13. A cavity is arranged in the front sleeve 31 of the lever. One end of the side sliding rod 32 extends into the cavity of the front sleeve 31 of the lever, and a trigger ejector rod 33 is fixedly arranged at one end of the side sliding rod 32 extending into the cavity of the front sleeve 31 of the lever. Trigger ejector rods 33 are fixedly arranged on the surface of the trigger ejector rod 33 at intervals. A dial shaft part 35 that can be driven to rotate by a tool is also arranged on the surface of the front sleeve 31 of the lever. A cross bar is fixedly arranged on the end face of the side sliding rod 32 extending into the cavity of the front sleeve 31 of the lever, and trigger teeth 34 are fixedly arranged at the bottom of the cross bar at intervals. A tooth disc meshed with the trigger teeth 34 is fixedly arranged on the end face of the dial shaft part 35 extending into the cavity of the front sleeve 31 of the lever. By rotating the dial shaft part 35, the side sliding rod 32 can be driven to displace, so as to adjust the position of the side sliding rod 32 inside the front sleeve 31 of the lever, and further adjust the distance between the two groups of trigger ejector rods 33. According to this structure, the distance between the two groups of sampling railings 15 can also be adjusted.
