Description

Technical Field

[0001] The invention relates to the technical field of geological survey, and in particular to a geological survey sample crushing device. Background Art

[0002] The collection of geological survey samples is the basis of geological research. Its purpose is to obtain samples of representative geological bodies or geological phenomena for subsequent analysis and research. For rocks, rock samples are obtained by drilling sampling, outcrop sampling or trench sampling. The crushing of geological survey samples is one of the important steps in sample pretreatment. Its purpose is to break the samples into smaller particles or powder for subsequent chemical analysis, mineral identification or rock physical property testing.

[0003] During the crushing process of geological survey samples, it is difficult for the crushing device to crush the samples to the required rock particle size in one go. Large rock particles are often mixed into the crushed rock particles, which is not conducive to subsequent analysis and testing of rock composition, and affects the geological survey results. In order to solve this problem, a screening mechanism is generally provided in the crushing device, but large-sized rock particles will be retained in the screening mechanism, which requires manual cleaning, and the large-sized rock particles need to be collected and crushed again, otherwise the screening mechanism will be blocked, affecting the feeding. This process often requires shutdown processing, affecting the crushing efficiency of geological survey samples. Summary of the invention

A conveyor belt 10 is provided for rotation inside the shell 9, and drive plates 11 are provided on the outer annular surface of the conveyor belt 10 at intervals. The drive plates 11 are rectangular plates, and the side surfaces of each drive plate 11 (referring to the front and rear side surfaces and the outer end surfaces of the drive plates) are in sliding contact with the inner side surface of the shell 9, and the outer ends of the plurality of drive plates 11 are all inclined clockwise along the annular direction of the conveyor belt 10. A transmission member is provided between the feeding member and the sieve plate 6. When the conveyor belt 10 rotates, the sieve plate 6 is driven by the transmission member to rotate with the rotating shaft 7 as the rotating axis, so that the right end of the sieve plate 6 is upward or the right end of the sieve plate 6 is reset.

[0020] The sieve plate 6 is a rectangular plate with sieve holes 14 evenly distributed on it. The left and right ends of the sieve plate 6 are both arc-shaped surfaces. The central angle corresponding to the arc groove is greater than 15 degrees and less than 30 degrees.

[0022] The upper end of the arc groove 8 is higher than the lower end of the feed hole 13 , and the lower end is lower than the lower end of the feed hole 13 . The front and rear ends of the rotating shaft 7 respectively penetrate the front and rear side plates of the box body 1 .

[0023] The transmission member includes a gear 18, a torsion spring 19, a pulley 20 and a pulley 21. The front end of the rotating shaft 7 is sleeved and fixed with the gear 18, and the rear end is covered with a torsion spring 19. One end of the torsion spring 19 is connected to the rear side plate of the box body 1, and the other end is connected to the peripheral wall of the rotating shaft 7. The front end of the transmission roller 2 16 is connected to the pulley 1 20. A rotating shaft 22 is rotatably provided on the front side plate of the box body 1 below the gear 18. A fan ring plate 23 with a downward protrusion is connected to the rotating shaft. The gear 18 and the fan ring plate 23 are opposite to each other up and down. Teeth 24 are provided on the outer ring surface of the fan ring plate. When the fan ring plate 23 protrudes upward, the teeth 24 on the fan ring plate 23 mesh with the gear 18. The rotating shaft 22 is sleeved with a pulley 21 located in front of the fan ring plate 23, and a belt 25 is commonly sleeved outside the pulley 1 20 and the pulley 2 21.

[0024] When the torsion spring 19 is in a natural state, the sieve plate 6 is higher on the left and lower on the right, and the right end contacts the lower end of the arc groove 8; when the fan ring plate 23 rotates clockwise until the teeth 24 on the fan ring plate 23 disengage from the gear 18, the gear 18 rotates counterclockwise to the limit state.

[0025] When the teeth 24 on the fan ring plate 23 mesh with the gear 18 and rotate counterclockwise to the limit state, the sieve plate 6 is in a state of being lower on the left and higher on the right, and the right end contacts the upper end of the arc groove 8.

[0026] The bottom surface of the discharge hole 12 is an inclined surface that is higher on the left and lower on the right. A guide plate 26 is provided on the upper side of the left crushing roller 2. The guide plate 26 is a rectangular plate that is higher on the left and lower on the right. The left end of the guide plate 26 is connected to the right side plate of the shell 9 at the lower side of the discharge hole 12; the bottom surface of the feed hole 13 is an inclined surface that is lower on the left and higher on the right.

[0027] A fixing plate 27 is provided inside the loop of the conveyor belt 10 , and the fixing plate 27 is fixedly connected to the front and rear side plates of the shell 9 . The inner side surface of the conveyor belt 10 slidably contacts the fixing plate 27 , and the conveyor belt 10 rotates clockwise.

[0028] Every two adjacent driving plates 11 , the housing 9 and the conveyor belt 10 together form a cavity.

[0029] When in use, the motor 17 drives the transmission roller 2 16 to rotate clockwise (the clockwise rotation of the transmission roller 2 16 is Figure 3 The transmission roller 2 16 drives the conveyor belt 10 to rotate clockwise, and the plurality of driving plates 11 rotate clockwise along with the conveyor belt 10. When the transmission roller 2 16 rotates, the pulley 1 20 is driven to rotate. The pulley 1 20 drives the pulley 2 21 to rotate clockwise via the belt 25. The pulley 21 drives the fan ring plate 23 to rotate clockwise via the rotating shaft 22. When the fan ring plate 23 rotates clockwise until the teeth 24 on the fan ring plate 23 engage the gear 18, the driving gear 18 drives the rotating shaft 7 to rotate counterclockwise. The rotating shaft 7 drives the sieve plate 6 to rotate counterclockwise, and the sieve plate 6 gradually changes from a state of left high and right low to a state of left low and right high. The torsion spring 19 is twisted. When the teeth 24 on the fan ring plate 23 are separated from the gear 18, the sieve plate 6 is driven by the rotating shaft 7 to return to the initial state of left high and right low under the restoring force of the torsion spring 19; therefore, during the clockwise rotation of the conveyor belt 10, the sieve plate 6 can be driven to rotate counterclockwise or clockwise reciprocatingly through the transmission member, so that the sieve plate 6 changes from left low and right high or left high and right low; The two crushing rollers 2 rotate relative to each other, and the rock sample to be crushed is fed into the box 1. The rock sample is crushed by the two relatively rotating crushing rollers 2, and the crushed rock particles fall on the sieve plate 6. When the sieve plate 6 changes from low on the left to high on the right or high on the left to low on the right, it can drive the rock particles on the sieve plate 6 to roll, and the rock particles smaller than the aperture of the sieve hole 14 on the sieve plate 6 move downward through the sieve hole 14 and are discharged through the lower hopper 3; and the rock particles larger than the aperture of the sieve hole 14 roll to the left on the top surface of the sieve plate 6 when the sieve plate 6 is in the state of low on the left and high on the right, and enter the shell 9 through the feed hole 13. Since each adjacent two driving plates 1 1 and the shell 9 and the conveyor belt 10 together form a cavity, and the rock particles entering the shell 9 will be pushed into the cavity connected to the feed hole 13, and the driving plate 11 where the cavity is located pushes the rock particles to move clockwise along the inner side of the shell 9. Since the driving plate 11 on the right side of the conveyor belt 10 is in a state of being higher on the left and lower on the right, after the rock particles are driven to the upper right part of the shell 9 by the driving plate 11, the rock particles are guided by the driving plate 11 on the right side of the conveyor belt 10 under the action of their own weight, pushed to the discharge hole 12, and enter the box body 1 again, and are crushed by the two crushing rollers 2 again under the guidance of the guide plate 26; Therefore, the present invention can automatically feed rock particles larger than the aperture of the sieve plate sieve hole 14 into the box body 1 again, and be crushed by the crushing roller 2 until the rock particles are completely crushed to a size smaller than the aperture of the sieve hole 14 without manual operation.
