Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a solid mineral separation and screening device for geological exploration. Background Technology

[0002] Geological exploration is short for geological exploration work. It is a kind of investigation and research work that focuses on different aspects of the geological conditions of a certain area, such as rocks, stratigraphic structure, minerals, groundwater, landforms, etc. Different geological exploration work is carried out according to different purposes. After the minerals are mined, suitable minerals need to be screened.

[0003] According to announcement number CN216500685U, a solid mineral separation and screening device for geological exploration is disclosed. This technology discloses "a solid mineral separation and screening device for geological exploration, including a housing. A telescopic rod is provided at the lower corner of the housing, and a spring is sleeved on the outer side of the telescopic rod. A vibration motor is provided on the side wall of the housing. Through grooves are evenly and alternately arranged on the left and right side walls of the housing, and the through grooves are inclined downwards towards the center of the housing. A filter plate is fitted inside the through groove. Limiting plates are fixed to the front and rear inner walls of the housing on the upper and lower sides of the filter plate, respectively. The filter plate is far from the corresponding through groove..." The device has a through groove 2 on the side wall of the box above the first end of the trough, a groove 1 on the inner wall above the through groove 2, a groove 2 on the outer wall of the box corresponding to the groove 1, a horizontal plate in the groove 2, a vertical plate in the groove 2, and the upper end of the vertical plate is connected to the lower end of the horizontal plate. The device has the following technical effects: it can perform multi-layer screening of ore fragments, and the filter plates used for screening are replaceable. Different pore sizes of filter plates can be selected according to the size to be screened. At the same time, the side wall of the device is provided with vertical plates that can be moved up and down respectively corresponding to the filter plates, which can facilitate the removal of the screened ore fragments.

[0004] The above scheme achieves screening by using multiple inclined screens in conjunction with a vibrating motor. Factors such as the inclination angle of the screens, vibration frequency, and amplitude will affect the screening effect. If the inclination angle of the screens is too large, the material will stay on the screens for a short time, resulting in insufficient screening. If the inclination angle is too small, the material will move slower on the screens, reducing screening efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a solid mineral separation and screening device for geological exploration, which features efficient screening of ore through the synchronous rotation of a primary drum screen, a secondary drum screen, and a tertiary drum screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid mineral separation and screening device for geological exploration, comprising a base frame and a top frame fixed to the top of the base frame, characterized in that: a processing mechanism is provided on the base frame for solid mineral separation, the processing mechanism comprising:

[0007] Crushing assembly, located on top of the top frame and used for crushing ore;

[0008] Conveying assembly, located inside the top frame and used for conveying ore;

[0014] Preferably, the driving component includes a second motor mounted on the outer wall of the rear end of the housing, pulleys fixed at the front ends of the primary, secondary, and tertiary drum screens, and belts installed between adjacent pulleys.

[0015] This invention provides a solid mineral separation and screening device for geological exploration. Compared with the prior art, it has the following advantages:

[0016] 1. Through the synchronous rotation of a primary, secondary, and tertiary drum screen, when the ore falls onto the primary drum screen, the ore smaller than the screen openings falls onto the corresponding slope below after being screened by the primary drum screen; the remaining ore is sent to the secondary drum screen, and the ore smaller than the screen openings falls onto the corresponding slope below after being screened by the secondary drum screen; finally, the remaining ore is sent to the tertiary drum screen, and the ore smaller than the screen openings falls onto the corresponding slope below after being screened by the tertiary drum screen; thus achieving efficient screening of the ore.

[0017] 2.

[0029] Conveying assembly 32 is installed inside the top frame 2 and is used for conveying ore;

[0030] The screening assembly 33 includes a housing 331 inside the base frame 1, three ramps 332 fixed at the lower end inside the housing 331, two baffles 333 fixed inside the housing 311 and located between adjacent ramps 332, a primary drum screen 334, a secondary drum screen 335 and a tertiary drum screen 336 rotatably mounted inside the upper end of the housing 311 and located directly above the upper ramp 332, and a drive unit 337 provided on the housing 311 for driving the primary drum screen 334, the secondary drum screen 335 and the tertiary drum screen 336 to rotate.

[0031] In this embodiment, the primary drum screen 334, the secondary drum screen 335, and the tertiary drum screen 336 rotate synchronously. When the ore falls onto the primary drum screen 334, the ore smaller than the screen openings of the primary drum screen 334 falls onto the corresponding slope 332 below. The remaining ore is fed to the secondary drum screen 335, and the ore smaller than the screen openings of the secondary drum screen 335 falls onto the corresponding slope 332 below. Finally, the remaining ore is fed to the tertiary drum screen 336, and the ore smaller than the screen openings of the secondary drum screen 335 falls onto the corresponding slope 332 below. This achieves efficient screening of the ore.

[0032] Specifically, the crushing assembly 31 includes a housing 311 fixed to the top of the top frame 2, two shafts 312 rotatably mounted inside the housing 311, several blades 313 fixed to the outer wall of the shafts 312, gears 314 fixed to the outer ends of the two shafts 312, and the two gears 314 meshing and transmitting power between each other. A reduction motor 315 is mounted on the top of the top frame 2 and is used to drive one of the shafts 312 to rotate.

[0033] In this embodiment, the ore is poured into the housing 311 and driven to rotate by the geared motor 315. The shaft 312 rotates synchronously in the opposite direction through the gear 314 and another gear 314, so that the blades 313 on the two shafts 312 crush the ore, making the crushed ore smaller than the mesh size of the three-stage drum screen 336.

[0034] Specifically, the crushing assembly 31 also includes several inclined baffles 316 fixed to the inner walls of both ends of the housing 311, and the inclined baffles 316 are located between adjacent blades 313.

[0035] In this embodiment, the inclined baffle 316 can guide the ore into the housing 311, ensuring that the ore can be crushed in an orderly manner.

[0036] Specifically, the conveying assembly 32 includes a trough 321 fixed inside the top frame 2, a spiral blade 322 rotatably mounted inside the trough 321, and a first motor 323 mounted on the outer wall of the trough 321 for driving the spiral blade 322.

[0037] In this embodiment, the first motor 323 drives the spiral blades 322 to rotate, thereby conveying the ore that falls into the trough 321.

[0038] Specifically, the conveying assembly 32 also includes a discharge port 324 opened at the bottom of the trough 321, and the discharge port 324 is located directly above the primary drum screen 334.

[0039] In this embodiment, the ore conveyed by the conveying component 32 can fall onto the primary drum screen 334 through the discharge port 324.

[0040] Specifically, the drive unit 337 includes a second motor 3373 installed on the outer wall of the rear end of the housing 331, pulleys 3371 fixed at the front ends of the primary drum screen 334, the secondary drum screen 335 and the tertiary drum screen 336, and belts 3372 installed between adjacent pulleys 3371.

[0041] In this embodiment, the first-stage drum screen 334 is driven to rotate by the second motor 3373, and the second-stage drum screen 335 and the third-stage drum screen 336 are driven to rotate synchronously by the pulley 3371 and the belt 3372.

[0042] The working principle and usage process of this utility model are as follows: First, the ore is poured into the housing 311, and the shaft 312 is driven to rotate by the reduction motor 315. The shaft 312 drives the other shaft 312 to rotate synchronously in the opposite direction through the gear 314 and another gear 314, so that the blades 313 on the two shafts 312 crush the ore.

[0043] Then, the crushed ore falls into the trough 321 and is driven by the first motor 323 to rotate the spiral blades 322, thereby conveying the ore in the trough 321. The conveyed ore can fall onto the primary drum screen 334 through the discharge port 324.

[0044] Finally, the second motor 3373 drives the primary drum screen 334 to rotate, and the pulley 3371, in conjunction with the belt 3372, drives the secondary drum screen 335 and the tertiary drum screen 336 to rotate synchronously. When the ore falls onto the primary drum screen 334, the ore smaller than the screen openings of the primary drum screen 334 falls onto the corresponding slope 332 below. The remaining ore is sent to the secondary drum screen 335, and the ore smaller than the screen openings of the secondary drum screen 335 falls onto the corresponding slope 332 below. Finally, the remaining ore is sent to the tertiary drum screen 336, and the ore smaller than the screen openings of the secondary drum screen 335 falls onto the corresponding slope 332 below. This achieves efficient screening of the ore.
