A sample crushing device for geological exploration

Abstract

The present invention relates to the technical field of crushers, and specifically relates to a sample crushing device for geological exploration, including a crushing housing and a crushing roller. The crushing roller is arranged inside the crushing housing. A driving shaft is connected in the axial direction of the crushing roller. A connecting gear is arranged at the lower part of the driving shaft. A number of connecting components are arranged inside the crushing roller. Connecting racks are arranged in the length direction of the connecting components. The connecting gear is meshed and connected with the connecting rack. By arranging a plurality of connecting components inside the crushing roller and connecting them with the driving shaft, when the crushing roller is extruded by larger substances, the driving shaft is driven to rotate reversely by the crushing motor, so that the driving shaft pulls the connecting arm to move towards the axial direction of the driving shaft, causing the crushing roller to lose support and the extruded object to fall, which can effectively avoid damage to the crushing roller and the crushing cavity caused by geological samples and ensure the efficient use of geological samples.

Description

Technical Field

[0001] The present invention relates to the technical field of crushers, and more specifically, it is a sample crushing device for geological exploration. Background Art

[0002] In the field of geological exploration, in order to facilitate the analysis of the elemental composition of geological samples, it is often necessary to crush geological samples. Conventional sample crushing is carried out by a cone crusher.

[0003] When a cone crusher is in use, the cone and the crushing wall extrude and crush the material to be crushed. Sometimes, geological samples or ores may get stuck between the cone and the crushing wall, making it difficult to remove, easily causing damage to the cone and the crushing wall, and affecting the crushing efficiency of geological samples. Therefore, it is necessary to set up a sample crushing device for geological exploration to facilitate the dropping of the stuck samples, prevent damage to the cone and the crushing wall caused by geological samples, and ensure the crushing efficiency of geological samples. Summary of the Invention

[0004] To solve the above problems, the present invention provides a sample crushing device for geological exploration.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a sample crushing device for geological exploration, including a crushing housing and a crushing roller. The crushing roller is arranged inside the crushing housing. A driving shaft is connected in the axial direction of the crushing roller. A connecting gear is arranged at the lower part of the driving shaft. Several groups of connecting components are arranged inside the crushing roller. A connecting rack is arranged in the length direction of the connecting components. The connecting gear is meshed with the connecting rack.

[0006] As an optimization, a connecting cavity is arranged inside the crushing roller. A number of limiting grooves are recessed inside the connecting cavity. The limiting grooves are arranged opposite to the connecting components.

[0007] As an optimization, the connecting component includes two connecting arms arranged oppositely. The two connecting arms are arranged in a central symmetry along the axial direction of the driving shaft. The length direction of the connecting arm is perpendicular to the axial direction of the driving shaft. A sliding groove is arranged in the length direction of the connecting arm. An L-shaped limiting rod is arranged inside the connecting cavity. The L-shaped limiting rod is slidably connected with the sliding groove.

[0008] As an optimization, a crushing cavity and an installation cavity are arranged inside the crushing housing. The installation cavity is arranged above the crushing cavity;

[0009] The crushing roller is arranged inside the crushing cavity. A crushing motor is arranged inside the installation cavity. The output shaft of the crushing motor is fixedly connected with the axial direction of the crushing roller. A number of pressure sensors arranged in a circumferential array are arranged on the top of the crushing motor.

[0010] As an optimization, a circular opening is provided at the top of the crushing chamber, and a number of connecting rods are evenly arranged inside the circular opening. A spherical joint is connected between the connecting rod and the drive shaft.

[0011] As an optimization, the lower part of the crushing chamber converges, and the lower part of the crushing roller converges. The distance between the crushing roller and the inner side surface of the crushing chamber gradually decreases from top to bottom.

[0012] The beneficial effect of this solution is that a sample crushing device for geological exploration has the following advantages:

[0013] A plurality of connecting components are arranged inside the crushing roller and are connected to the drive shaft through the connecting components. When the crushing roller is extruded by a relatively large object, the drive shaft is driven to rotate in the reverse direction by the crushing motor, so that the drive shaft pulls the connecting arm to move towards the axis direction of the drive shaft, causing the crushing roller to lose support and allowing the extruded object to fall, which can effectively prevent the geological sample from damaging the crushing roller and the crushing chamber and ensure the efficient use of the geological sample.

[0022] Such as Figure 1 , 3As shown in the figure, a sample crushing device for geological exploration includes a crushing housing 1 and a crushing roller 2. The crushing roller 2 is arranged inside the crushing housing 1. A drive shaft 3 is connected in the axial direction of the crushing roller 2. A connecting gear 4 is provided at the lower part of the drive shaft 3. A number of connecting components are provided inside the crushing roller 2. A connecting rack is provided in the length direction of the connecting components. The connecting gear 4 is meshed and connected with the connecting rack.

[0023] An inlet channel is provided at the upper part of the crushing housing 1, and the bottom of the inlet channel is open.

[0024] As Figure 6 、 7 shown in the figure, a connecting cavity 5 is provided inside the crushing roller 2. A number of limiting grooves 6 are formed by concave-convex inside the connecting cavity 5. The limiting grooves 6 are arranged opposite to the connecting components.

[0025] The limiting grooves 6 are used to accommodate the outer ends of the connecting components.

[0026] As Figure 4 、 6 shown in the figure, the connecting components include two connecting arms 7 arranged oppositely. The two connecting arms 7 are arranged in a central symmetry along the axial direction of the drive shaft 3. The length direction of the connecting arms 7 is perpendicular to the axial direction of the drive shaft 3. A sliding groove 9 is provided in the length direction of the connecting arms 7. An L-shaped limiting rod 8 is provided inside the connecting cavity 5. The L-shaped limiting rod 8 is slidably connected with the sliding groove 9.

[0027] Limiting end blocks are provided at the outer ends of the connecting arms 7. The limiting grooves 6 are used for the limiting end blocks. The limiting end blocks are integrally formed with the connecting arms 7.

[0028] As Figure 1 shown in the figure, a crushing cavity 10 and an installation cavity 11 are provided inside the crushing housing 1. The installation cavity 11 is arranged above the crushing cavity 10;

[0029] The crushing roller 2 is arranged inside the crushing cavity 10. A crushing motor 12 is provided inside the installation cavity 11. The output shaft of the crushing motor 12 is fixedly connected with the axial direction of the crushing roller 2. A number of pressure sensors 13 are provided at the top of the crushing motor 12 and are arranged in a circumferential array.

[0030] The inlet channel is communicated with the inside of the crushing cavity 10. The crushing cavity 10 and the installation cavity 11 are coaxially arranged. The diameter of the channel between the installation cavity 11 and the crushing cavity 10 is larger than the diameter of the drive shaft 3. The height of the crushing cavity 10 is larger than the height of the crushing roller 2.

[0031] As Figure 2 shown in the figure, a circular opening is provided at the top of the crushing cavity 10. A number of connecting rods are evenly provided inside the circular opening. A spherical joint is connected between the connecting rods and the drive shaft 3.

[0032] Due to the arrangement of the connecting rod and the spherical joint, the lower part of the crushing roller 2 can swing.

[0033] As Figure 1 shown, the lower part of the crushing chamber 10 converges, the lower part of the crushing roller 2 converges, and the distance between the lower part of the crushing roller 2 and the inner side surface of the crushing chamber 10 gradually decreases from top to bottom.

[0034] This solution further includes a controller, the position of which is set by the staff according to the actual situation during operation. The controller is used to control all the electrical appliances in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication devices, lights, speakers, and microphones; the controller is an Intel processor, AMD processor, PLC controller, ARM processor, or single-chip microcomputer, and the motherboard, memory module, storage medium, and power supply are also used in supporting. The power supply is mains electricity or a lithium battery.

[0035] When the device is in specific use, geological samples are injected downward from the feeding channel. The crushing motor 12 drives the crushing roller 2 to rotate through the drive shaft 3, and the samples are squeezed and crushed by the crushing roller 2 and the crushing chamber 10.

[0036] When a large and hard geological sample gets stuck between the crushing roller 2 and the crushing outer shell 1, the pressure sensor 13 on the upper side of the relative position of the sample is squeezed. By setting a certain pressure threshold through the controller, when the pressure value detected by the pressure sensor 13 is greater than the pressure threshold, the crushing motor 12 reverses.

[0037] As Figure 3 shown, when the drive shaft 3 reverses, that is, rotates counterclockwise, the connecting gear 4 drives the connecting rack to move, so that the connecting arm 7 moves away from the crushing roller 2. The end of the connecting arm 7 does not contact the inner wall of the connecting cavity 5, and the crushing roller 2 loses support, causing the geological sample to fall from between the crushing roller 2 and the crushing chamber 10.

[0038] When the crushing motor 12 reverses until the connecting gear 4 moves to the middle of the length direction of the connecting arm 7, the sample drops. The crushing motor 12 continues to rotate forward, the connecting gear 4 drives the connecting arm 7 to move towards the inner wall of the connecting cavity 5, supports the inner wall of the crushing roller 2 through the connecting arm 7, the crushing motor 12 drives the crushing roller 2 to rotate forward, and the sample is crushed by the crushing roller 2.

The patent protection scope of the present invention includes but is not limited to the product forms and styles of the above specific implementation manners. Any geological exploration sample crushing device that conforms to the claims of the present invention and any appropriate changes or modifications made by those of ordinary skill in the relevant technical fields shall fall within the patent protection scope of the present invention.
