Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, an embodiment of the present invention provides an apparatus for integrating sample crushing and screening, which can be used in a wet-dry cycle test of soft rock and soil, and mainly includes: a sample disruption structure 10, a screening structure 20 and a connection 50 connecting said sample disruption structure 10 and said screening structure 20.
The sample crushing structure 10 comprises a movable grinding disc 11 and a static grinding disc 12, wherein the upper surface of the movable grinding disc 11 is a plane parallel to the horizontal plane, and the lower surface of the movable grinding disc 11 is a curved surface which is convex downwards, that is, the lower end region of the movable grinding disc 11 facing the static grinding disc 12 is provided with a convex arc crushing part 111 which is convex downwards. It is connected with a carousel 16 to move the mill 11 through a transmission 15, the sun gear of carousel 16 is connected with a motor 17's pivot 171, and is specific, transmission 15 is the conveyer belt, motor 17 passes through pivot 171 drive carousel 16 rotates in the horizontal direction, carousel 16 passes through conveyer belt 15 drives it rotates at the horizontal direction to rotate mill 11.
The lower surface of the static grinding disc 12 is mounted on a bracket 30 and supported by the bracket 30, the static grinding disc 12 is provided with a concave arc crushing part 121 which is concave downwards in the direction of the movable grinding disc 11, the convex arc crushing part 111 corresponds to the concave arc crushing part 121, and as shown in fig. 1, the curvature radius of the arc-shaped profile of the longitudinal section of the convex arc crushing part 111 is slightly smaller than that of the arc-shaped profile of the longitudinal section of the concave arc crushing part 121, so that a gap is formed between the convex arc crushing part 111 and the concave arc crushing part 121, the gap is gradually reduced from top to bottom, and the gap between the movable grinding disc 11 and the static grinding disc 12 forms a crushing section 13. The bottom of the concave arc crushing part 121 of the static grinding disc 12 is penetrated by a conduit 18, the conduit 18 extends downwards to extend into the screening structure 20 so as to communicate the crushing area 13 with the inside of the screening structure 20, and the conduit 18 penetrates through the lowest part of the middle position of the concave arc crushing part 121.
The height-adjustable of support 30, it is specific, support 30 is including the mount 31 that is located the lower extreme, the adjustable shelf 32 that is located the upper end and will the adjustable shelf 32 is fixed in the fastening bolt 33 of mount 31, the regional cover in upper end of mount 31 is located the regional periphery of lower extreme of adjustable shelf 32, through the adjustment tighten bolt 33, can adjust thereby the height of adjustable shelf 32 realizes the adjustment the height of support 30, and then the realization adjustment quiet mill 12 with move the clearance size between the mill 11, adjust promptly the size of broken interval 13 to let the grinding degree of ground have the adjustability. The upper end of the crushing area 13 is provided with a feed inlet 131, and rock soil enters the crushing area 13 from the feed inlet 131.
In order to prevent dust from flying and polluting the environment in the grinding process, a dust cover 14 is arranged around the periphery of the static grinding disc 12, the opening direction of the dust cover 14 faces upwards, so that the ground can be effectively prevented from splashing or spreading around during grinding, pollution is controlled, and the environment comfort level is improved.
Each screening box 22 is provided with a screen (not shown), and the screening apertures of the screens are gradually reduced from top to bottom. After the ground rock-soil enters the screening structure 20 through the guide pipe 18, the ground rock-soil is screened by the plurality of screens in a multi-stage manner from top to bottom, so that rock-soil with different particle sizes can be conveniently screened from different screens.
The screening box 22 is provided with a clamping structure 23, such as a snap ring, the screening main body 21 is provided with a clamping matching structure 24 corresponding to the clamping structure 23, such as a buckle, and the screening box 22 is fixed on the screening main body 21 under the matching of the clamping structure 23 and the clamping matching structure 24. Like this, when the screening structure 20 needs the ejection of compact after working for a period, can open block structure 23 with block cooperation structure 24, then will correspond screening box 22 is followed in screening main part 20 is taken out, then will in the screening box 22 the ground on the screen cloth is cleared up out, accomplishes a screening.
In operation, the motor 17 is started, the movable grinding disc 11 rotates relative to the static grinding disc 12 through the rotating shaft 171, the rotating disc 16 and the conveyor belt 15, and meanwhile, the screening structure 20 rotates and vibrates under the rotation of the movable grinding disc 11. The rock soil to be crushed is poured from the feeding hole 131, the rock soil enters the crushing interval 13 and then is ground and crushed by the movable grinding disc 11 and the static grinding disc 12, and gradually enters the bottom end of the crushing interval 13 from the upper end of the crushing interval 13 along with the rotation of the movable grinding disc 11, and as the curvature radius of the arc-shaped profile of the longitudinal section of the convex arc crushing part 111 is slightly smaller than that of the arc-shaped profile of the longitudinal section of the concave arc crushing part 121, the closer to the bottom end of the crushing interval 13, the narrower the crushing interval 13 is, the larger the grinding force between the movable grinding disc 11 and the static grinding disc 12 is, the more sufficient the grinding force is. The finally sufficiently ground rock soil enters the screening structure 20 through the guide tube 18 at the bottom end of the concave arc crushing part 121. The screening structure 20 is driven by the connecting member 50 to rotate and vibrate along with the rotation of the movable grinding disc 11, so that ground rock and soil entering the screening structure 20 are screened, the rock and soil are screened in multiple layers and multiple levels through the screening boxes 22, the rock and soil with different particle sizes are left on the screening nets in the screening boxes 22, the clamping structures 23 and the clamping matching structures 24 are opened, then the corresponding screening boxes 22 are extracted from the screening main body 21, and then the rock and soil on the screening nets in the screening boxes 22 are cleaned out, so that primary screening is completed.
Compared with the prior art, the device integrating sample crushing and screening drives the movable grinding disc 11 to rotate relative to the silent disc 12 to grind rock soil by the transmission device 15 which is linked by the turntable 16, and the rock soil is gradually ground and fully ground by matching the convex arc crushing part 111 with smaller curvature radius and the concave arc crushing part 121 with larger curvature radius, so that the device has the advantages of simple structure, convenience in control and operation, effective labor release, production efficiency improvement and production cost saving. Moreover, the movable grinding disc 11 and the static grinding disc 12 are driven by the same motor 17, so that the structure is simplified, and the manufacturing cost is reduced.
