Description

Technical Field

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

[0002] Geological and geotechnical engineering investigation refers to the activities of identifying, analyzing, evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and compiling investigation documents according to the requirements of the construction project. The task of geotechnical engineering investigation is to correctly reflect the engineering geological conditions of the site and the influence of geotechnical properties according to the requirements of different investigation stages. In the process of geological and geotechnical investigation and research, crushing equipment will be used to crush the geotechnical exploration samples in order to facilitate the characteristic analysis of the rock and soil.

[0003] In the process of multi-stage crushing, it is found that the existing rock and soil exploration sample crushing device has certain defects: multi-stage crushing is generally arranged in sequence longitudinally or transversely, and the rock and soil enters the secondary crushing chamber from the primary crushing chamber, and then enters the tertiary crushing chamber from the secondary crushing chamber, and then is taken out for grinding after the tertiary crushing. In this way, firstly, the overall layout occupies a large space, is not compact enough, and requires multiple driving sources; secondly, there is no cross-connection between the crushing chambers at each level, and they can only be connected sequentially. Therefore, for the rock and soil in the primary crushing chamber that meets the specifications of the tertiary crushing chamber or the grinding chamber, or for the rock and soil in the secondary crushing chamber that meets the specifications of the grinding chamber, they can only be crushed and ground in the order of the primary crushing chamber, the secondary crushing chamber, the tertiary crushing chamber and the grinding chamber, and cannot cross the levels to enter the crushing chamber of the corresponding level or directly enter the grinding chamber, which leads to the occupation of invalid crushing space and reduced efficiency. Summary of the invention

[0004] In view of the problems of the prior art, the present invention provides a geological exploration sample crushing device, comprising a feeding mechanism, a crushing mechanism and a storage mechanism arranged in sequence. The feeding mechanism transports rock and soil samples to the crushing mechanism for crushing, and the crushing mechanism sends the crushed powdered samples to the storage mechanism for storage.

[0005] The feeding mechanism includes a conveyor belt and a motor. The motor is used to drive the conveyor belt to move, and the conveyor belt transports the rock and soil samples to the feeding port of the crushing mechanism.

[0006] The crushing mechanism includes a mounting frame, a coarse crushing device and a fine crushing device. The coarse crushing device is installed on the mounting frame, and the fine crushing device is arranged below the mounting frame. The coarse crushing device includes a feed port, a primary crushing structure, a screening net and a secondary crushing structure arranged in sequence. A primary crushing structure is arranged below the feed port. The primary crushing structure crushes the rock and soil and then enters the screening net. Smaller particles directly enter the fine crushing device, and larger particles enter the fine crushing device after being crushed by the secondary crushing structure.

[0007] The primary crushing mechanism includes a driving roller, a driven roller, and a driving motor. The driving motor drives the driving roller to rotate. The driving roller and the driven roller are rotatably arranged below the feed inlet. The surfaces of the driving roller and the driven roller are provided with crushing gear rings arranged in an array. The crushing gear rings on the driving roller and the driven roller are meshed with each other in a staggered manner. The driving motor drives the driven roller to rotate by using a linkage gear. The driving motor is connected to the input shaft of the gear reduction box through a reduction transmission mechanism. The output shaft of the gear reduction box is connected to one end of the driving crushing roller through a coupling. The linkage gear is arranged at one end of the driving crushing roller and the driven crushing roller close to the coupling. The driving roller makes the driven roller rotate synchronously in opposite directions through the linkage gear, thereby crushing the material.

[0008] The secondary crushing mechanism includes a crushing disc, a stone mill driving ring, a crushing stone mill, the outer wall of the stone mill, and a rotating shaft. The crushing disc is placed and installed on the upper surface of the outer wall of the stone mill. During operation, the crushing disc maintains its position relationship by its own gravity. When the force during the crushing process is relatively large, there will be a slight vibration. A through hole is provided in the center of the crushing disc, and a screening mesh is installed at the through hole. The screening mesh is conical. Larger-sized materials enter the crushing stone mill through the periphery of the screening mesh. They are ground into small particles through the friction between the upper surface of the crushing stone mill and the lower surface of the crushing disc and enter the discharge port along the inner side surface of the outer wall of the stone mill. A stone mill rotating shaft is installed at the center of the bottom of the crushing stone mill, and the stone mill rotating shaft is driven by a rotating motor below. The bottom of the outer wall of the stone mill is installed on a mounting block. The mounting block is arranged around the stone mill rotating shaft, and there is a set distance between the mounting block and the stone mill rotating shaft. The mounting block is provided with an arc-shaped sliding groove, and the outer wall of the stone mill can slide along the arc-shaped sliding groove. The angle of the arc-shaped sliding groove corresponds to the swinging angle of the swinging rotating cylinder.

[0009] A plurality of driving shafts are installed on the outer side of the upper part of the swinging rotating cylinder. The outer side of the bottom of the swinging rotating cylinder is connected to a connecting rod. One end of the connecting rod is connected through a hydraulic cylinder. The hydraulic cylinder is used to drive the connecting rod to rotate, and the connecting rod then drives the swinging rotating cylinder to swing. The swinging rotating cylinder drives the plurality of driving shafts to swing, and further drives the driving wheels on the plurality of driving shafts to swing, and further drives the stone mill driving ring to swing. During operation, the swinging rotating cylinder can be used to drive the stone mill driving ring to swing, thereby driving the swinging of the outer wall of the stone mill and driving the swinging of the crushing disc. It can assist the crushing stone mill to crush the rock and soil, and thus can effectively grind the rock and soil by the swinging of the crushing disc. It can ensure the crushing work and effectively avoid the problem of the crushing stone mill getting stuck during rotation. It can also use the swinging to vibrate the screening mesh and the rock and soil at the feed inlet, improving the feeding rate. And when the crushing stone mill is blocked and hindered from rotating due to the rotation of the rock and soil particles, the swinging of the crushing disc can effectively crush the stuck rock and soil, so that when the rock and soil wear and become smaller, the crushing stone mill can get rid of the stuck phenomenon and continue to rotate and work.

[0010] A plurality of drive shafts are arranged around the swinging rotary drum. The drive shafts are horizontally arranged. There are multiple drive shafts. One end of each drive shaft is provided with a drive wheel. An anti-slip rubber sleeve is sleeved outside the drive wheel. The drive wheel is used to fit against the outer side wall of the stone mill drive ring to drive the stone mill drive ring to swing. The anti-slip rubber sleeve can effectively prevent damage to the stone mill drive ring caused by excessive direct driving stress and can effectively limit the force. When the force is too large, the anti-slip rubber sleeve slides relative to the stone mill drive ring to avoid equipment damage. The hydraulic cylinder drives the connecting rod to swing, and then drives the rotating shaft to swing, thereby driving the stone mill drive ring to swing, which can assist the crushing stone mill to crush the rock and soil. The crushed rock and soil enter the fine crushing device through the discharge port. Among them, linear raised structures arranged in an array for grinding the rock and soil are provided on the upper surface of the crushing stone mill and the lower surface of the crushing disc.

[0011] The fine crushing device includes a housing. A fine crushing barrel is installed inside the housing. The fine crushing barrel is a horizontally arranged cylindrical shape. There is an opening above the fine crushing barrel. A drive rotating shaft is arranged inside the fine crushing barrel. The drive rotating shaft and the fine crushing barrel are coaxially arranged and can rotate relative to each other. A crushing shaft is sleeved on the drive rotating shaft. A plurality of connecting shafts are rotatably arranged on the crushing shaft. The connecting shafts are parallel to the axis of the crushing shaft. A corresponding crushing wheel is installed on each connecting shaft. The crushing wheel extends along the radial direction of the crushing shaft. The drive rotating shaft drives the crushing shaft to rotate. The crushing wheel forms a friction and hammering effect on the side wall of the crushing barrel under the drive of the crushing shaft. The crushing wheel is used to finely process the rock and soil so that the material can become fine and be discharged through the sieve holes to the discharge port and is transported to the storage mechanism for storage by the conveying mechanism arranged at the discharge port. When in use, the rock and soil after rough processing enters the inside of the crushing barrel through the top opening of the housing and the feeding port. The drive rotating shaft drives the crushing wheel to crush the rock and soil through the crushing shaft. During the crushing process of the material, the material with a smaller volume after crushing can pass through the sieve holes and be discharged from the bottom of the housing and be transported to the storage mechanism for storage.

[0012] The storage mechanism includes a box body, a storage box and a soil sample box. The box body is communicated with the discharge port of the fine crushing device through a conveying pipeline. The conveying pipeline is conveyed by a screw conveyor and can convey the rock and soil into the box body. A placing groove is provided inside the box body. The placing groove is welded to the storage box; a buffer pad is placed at the bottom of the placing groove. The soil sample box is placed in the placing groove and on top of the buffer pad. Each soil sample box is welded with a soil sample box handle for easy removal of each soil sample box; the soil sample box includes a box body and a box cover. The box body and the box cover are threadedly connected. Each soil sample box is provided with a sampling spoon for conveniently taking out the crushed rock and soil during the test.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows: The present invention provides a geological exploration sample crushing device, which conveys rock and soil to the feed inlet of the coarse crushing device by means of a conveyor belt, and performs preliminary crushing by using the crushing tooth ring of the primary crushing structure. After meeting the requirements, it enters the fine crushing device after being screened by the screening mesh. Those that do not pass through the screening mesh enter the secondary crushing structure and are further crushed by the crushing disc and the stone grinding drive ring. After meeting the requirements, they enter the fine crushing device. The fine crushing device uses a crushing wheel to finely crush the rock and soil. The materials with a smaller volume after crushing can be discharged from the bottom of the housing through the sieve holes and conveyed to the storage mechanism for storage; it can enter the corresponding-level crushing mechanism across levels, effectively saving the occupation of the crushing space and improving the crushing efficiency, so that the crushing accuracy and quality are greatly improved.
