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, and evaluating the geological and environmental characteristics and geotechnical conditions of a construction site, and compiling investigation documents based on the requirements of the construction project. The task of geotechnical engineering investigation is to accurately reflect the impact of the site's engineering geological conditions and geotechnical properties according to the requirements of different investigation stages. During the geological and geotechnical investigation process, crushing equipment is used to crush geotechnical exploration samples to facilitate the analysis of rock and soil properties.

[0003] In the process of multi-stage crushing, the existing rock and soil exploration sample crushing device is found to have 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, first, the overall layout occupies a large space, is not compact enough, and requires multiple driving sources; second, 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 response to the problems of the prior art, the present invention provides a geological exploration sample crushing device, which includes 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 drives 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 are crushed by the secondary crushing structure and then enter the fine crushing device.

[0007] The primary crushing mechanism includes an active roller, a driven roller and a driving motor. The driving motor drives the active roller to rotate. The active roller and the driven roller are rotatably arranged below the feed port. The surfaces of the active roller and the driven roller are provided with array-arranged crushing gear rings. The crushing gear rings on the active roller and the driven roller are arranged in an staggered meshing 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 active crushing roller through a coupling. The linkage gear is provided at one end of the active crushing roller and the driven crushing roller close to the coupling. The active roller causes the driven roller to rotate synchronously in the same direction through the linkage gear, thereby crushing the material.

[0008] The secondary crushing mechanism includes a crushing disc, a millstone drive ring, a crushing millstone, a millstone outer wall, and a rotating shaft. The crushing disc is mounted on the upper surface of the millstone outer wall. During operation, the crushing disc maintains its position using its own gravity. When subjected to high forces during the crushing process, it will vibrate slightly. A through-hole is located in the center of the crushing disc, where a conical screen mesh is installed. Larger materials pass through the mesh and enter the crushing millstone. Friction between the upper surface of the crushing millstone and the lower surface of the crushing disc causes them to be ground into smaller particles that travel along the inner surface of the millstone outer wall into the discharge port. The millstone shaft is mounted at the center of the bottom of the crushing millstone, and is driven by a rotating motor. The bottom of the millstone outer wall is mounted on a mounting block, which is positioned around the millstone shaft. The mounting block is spaced apart from the millstone shaft by a set distance. The mounting block has an arc-shaped chute along which the millstone outer wall slides. The angle of the arc-shaped chute corresponds to the swing angle of the swing drum.

[0009] Multiple drive shafts are mounted on the outer side of the upper portion of the swing drum, and the outer side of the bottom portion of the swing drum is connected to a connecting rod. One end of the connecting rod is connected via a hydraulic cylinder. The hydraulic cylinder drives the connecting rod to rotate, which in turn drives the swing drum to swing. The swing drum drives the multiple drive shafts to swing, which in turn drives the drive wheels on the multiple drive shafts to swing, which in turn drives the millstone drive ring to swing. During operation, the swing drum can drive the millstone drive ring to swing, thereby driving the outer wall of the millstone to swing, driving the crushing disk to swing, and thus assisting the crushing mill in crushing rock and soil. The swinging of the crushing disk can effectively grind the rock and soil, ensuring the crushing operation while effectively avoiding the problem of the crushing millstone being stuck. The swinging can also be used to vibrate the screen and the rock and soil at the feed port, thereby increasing the material discharge rate. When the crushing millstone is blocked by rock and soil particles, the swinging of the crushing disk can effectively crush the stuck rock and soil. When the rock and soil wear is reduced, the crushing millstone can break free of the jam and continue to rotate.

[0010] There are multiple drive shafts arranged around the swing drum. The drive shafts are arranged horizontally. There are multiple drive shafts. A drive wheel is provided at one end of the drive shaft. The outside of the drive wheel is covered with a non-slip rubber sleeve. The drive wheel is used to fit the outer wall of the stone mill drive ring and drive the stone mill drive ring to swing. The non-slip rubber sleeve can effectively prevent the stone mill drive ring from being damaged by excessive direct drive stress and can effectively limit the force. When the force is too large, the non-slip rubber sleeve and the stone mill drive ring slide relative to each other to avoid equipment damage. The hydraulic cylinder drives the connecting rod to swing, which in turn 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, the upper surface of the crushing stone mill and the lower surface of the crushing disc are both provided with an array of linear segment-shaped protrusions for grinding rock and soil.

[0011] The fine crushing device includes a housing, within which is mounted a fine crushing barrel. The fine crushing barrel is a horizontally arranged cylindrical barrel with an opening at its top. A drive shaft is disposed within the fine crushing barrel. The drive shaft and the fine crushing barrel are coaxially arranged and can rotate relative to each other. A crushing shaft is sleeved on the drive shaft. Multiple connecting shafts are rotatably disposed on the crushing shaft, parallel to the axis of the crushing shaft. Each connecting shaft is mounted with a corresponding crushing wheel. The crushing wheel extends radially along the crushing shaft. The drive shaft drives the crushing shaft to rotate. The crushing wheel, driven by the crushing shaft, creates a friction and hammering effect on the sidewalls of the crushing barrel. The crushing wheel is used to finely process rock and soil, allowing the material to be finely processed and discharged through the sieve holes to a discharge port. The material is then transported to a storage device for storage by a conveying mechanism provided at the discharge port. In use, the roughly processed rock and soil enters the crushing barrel through the top opening of the housing, through the feed port, and the drive shaft drives the crushing wheels via the crushing shaft to crush the rock and soil. During the material crushing process, smaller material is discharged from the bottom of the housing through the sieve holes and transported to a storage device for storage.

[0012] The storage mechanism includes a box, a storage box, and a soil sample box. The box is connected to the discharge port of the fine crushing device via a conveying pipeline. The conveying pipeline is transported by a screw conveyor to transport the rock and soil into the box. The box is equipped with a storage trough inside, which is welded to the storage box. A cushion is placed at the bottom of the storage trough, and the soil sample box is placed in the storage trough and on top of the cushion. Each soil sample box is welded with a handle for easy removal. The soil sample box consists of a box body and a box lid, which are threaded together. Each soil sample box is equipped with a sampling spoon to facilitate the removal of crushed rock and soil during the test.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] The present invention provides a geological exploration sample crushing device, which uses a conveyor belt to transport rock and soil to the feed port of a coarse crushing device, and uses the crushing gear ring of the primary crushing structure to perform preliminary crushing. The material that meets the requirements is screened by the screening net and then enters the fine crushing device. The material that does not pass through the screening net enters the secondary crushing structure and is further crushed by the crushing disk and the stone mill drive ring. After meeting the requirements, it enters the fine crushing device. The fine crushing device uses a crushing wheel to finely crush the rock and soil. After crushing, the smaller material can be discharged from the bottom of the shell through the sieve hole and transported to the storage mechanism for storage; it can enter the crushing mechanism of the corresponding level 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.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Example 1, as Figures 1 to 6 As shown, the present application provides a geological exploration sample crushing device, comprising a feeding mechanism 1, a crushing mechanism and a storage mechanism 7 arranged in sequence. The feeding mechanism 1 transports the rock and soil samples to the crushing mechanism for crushing, and the crushing mechanism sends the crushed powdered samples to the storage mechanism 7 for storage.

[0026] The feeding mechanism 1 includes a conveyor belt and a motor. The motor drives the conveyor belt to move, and the conveyor belt transports the rock and soil samples to the feeding port 2 of the crushing mechanism.

[0027] The crushing mechanism includes a mounting frame 5, a coarse crushing device and a fine crushing device 6. The coarse crushing device is installed on the mounting frame 5, and the fine crushing device 6 is arranged below the mounting frame 5. The coarse crushing device includes a feed port 2, a primary crushing structure 3, a screening net 109 and a secondary crushing structure 4 arranged in sequence. A primary crushing structure 3 is arranged below the feed port 2. The primary crushing structure 3 crushes the rock and soil and then enters the screening net 109. Smaller particles directly enter the fine crushing device 6, and larger particles enter the fine crushing device 6 after being crushed by the secondary crushing structure 4.

[0028] The primary crushing mechanism includes an active roller 201, a driven roller 202 and a driving motor. The driving motor drives the active roller 201 to rotate. The active roller 201 and the driven roller 202 are rotatably arranged below the feed port 2. The surfaces of the active roller 201 and the driven roller are provided with array-arranged crushing gear rings. The crushing gear rings on the active roller 201 and the driven roller 202 are arranged in an staggered meshing manner. The driving motor drives the driven roller 202 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 active crushing roller through a coupling. The linkage gear is provided at one end of the active crushing roller and the driven crushing roller close to the coupling. The active roller 201 causes the driven roller 202 to rotate synchronously in opposite directions through the linkage gear, thereby crushing the material.

[0029] The secondary crushing mechanism includes a crushing disc 101, a millstone drive ring 103, a crushing millstone 107, a millstone outer wall 108 and a rotating shaft. The crushing disc 101 is placed on the upper surface of the millstone outer wall 108. During operation, the crushing disc 101 uses its own gravity to maintain its position relationship. When the crushing process is subjected to greater force, it will vibrate slightly. A through hole is set in the center of the crushing disc 101, and a screen mesh 109 is installed at the through hole. The screen mesh 109 is conical. Larger materials enter the crushing millstone 107 through the four sides of the screen mesh 109. After friction between the upper surface of the crushing millstone 107 and the lower surface of the crushing disc 101, they are ground into small particles and enter the discharge port 106 along the inner side of the millstone outer wall 108. A millstone rotating shaft is installed at the bottom center of the crushing millstone 107, and the bottom of the millstone rotating shaft is driven by a rotating motor.

[0030] The bottom of the millstone outer wall 108 is installed on the mounting block 102, and the mounting block 102 is arranged around the millstone shaft. There is a set distance between the mounting block 102 and the millstone shaft. The mounting block 102 has an arc-shaped slide groove, and the millstone outer wall 108 can slide along the arc-shaped slide groove. The angle of the arc-shaped slide groove corresponds to the swing angle of the swinging drum.

[0031] Multiple drive shafts 104 are installed on the outer side of the upper part of the swinging drum, and the outer side of the bottom of the swinging drum is connected to a connecting rod. One end of the connecting rod is rotatably connected to the hydraulic cylinder 105, and the other end of the connecting rod is rotatably connected to the protrusion on the outer side of the swinging drum. The hydraulic cylinder is used to drive the connecting rod to move, and the connecting rod in turn drives the swinging drum to swing. The swinging drum drives multiple drive shafts 104 to swing, and then drives the drive wheels on the multiple drive shafts 104 to swing, and then drives the millstone drive ring 103 to swing. During operation, the swinging drum can be used to drive the stone mill drive ring 103 to swing, thereby driving the stone mill outer wall 108 to swing, and driving the crushing disk 101 to swing, which can assist the crushing stone mill 107 to crush the rock and soil, so that the swing of the crushing disk 101 can be used to effectively grind the rock and soil, which can ensure the crushing work and effectively avoid the problem of the crushing stone mill 107 rotating and getting stuck. The swing can also be used to vibrate the screen mesh 109 and the rock and soil at the feed port to increase the feeding rate, and when the crushing stone mill 107 is blocked due to the rotation of rock and soil particles, the swing of the crushing disk 101 can effectively crush the stuck rock and soil, so that when the rock and soil wear becomes smaller, the crushing stone mill 107 can get rid of the jamming phenomenon and continue to rotate.

[0032] A plurality of drive shafts 104 are arranged around the oscillating drum. The drive shafts 104 are arranged horizontally, and there are multiple drive shafts 104. A drive wheel is provided at one end of the drive shaft 104. The drive wheel is covered with a non-slip rubber sleeve. The drive wheel is used to fit the outer wall of the millstone drive ring 103 to drive the millstone drive ring 103 to swing. The non-slip rubber sleeve can effectively prevent the millstone drive ring from being damaged by excessive direct drive stress and can effectively limit the force. When the force is too strong, the non-slip rubber sleeve and the millstone drive ring slide relative to each other to prevent equipment damage. The hydraulic cylinder 105 drives the connecting rod to swing, which in turn drives the rotating shaft to swing, and thus drives the millstone drive ring 103 to swing, which can assist the crushing millstone 107 in crushing the rock and soil. The crushed rock and soil enter the fine crushing device 6 through the discharge port 106. Among them, the upper surface of the crushing millstone 107 and the lower surface of the crushing disc 101 are both provided with an array of linear segment-shaped protrusions for grinding rock and soil.

[0033] The fine crushing device 6 includes a shell, in which a fine crushing barrel 602 is installed. The fine crushing barrel 602 is a horizontally arranged cylindrical barrel with an opening on the top of the fine crushing barrel 602. A driving shaft 601 is provided in the fine crushing barrel 602. The driving shaft 601 and the fine crushing barrel 602 are coaxially arranged and can rotate relative to each other. A crushing shaft 603 is sleeved on the driving shaft 601. A plurality of connecting shafts 605 are rotatably provided on the crushing shaft 603. The connecting shafts 605 are parallel to the axis of the crushing shaft 603. Each connecting shaft 605 is equipped with a corresponding crushing wheel 604. The crushing wheel 604 extends in the radial direction of the crushing shaft 603. The driving shaft 601 drives the crushing shaft 603 to rotate. The crushing wheel 604 forms a friction and hammering effect on the side wall of the crushing barrel under the drive of the crushing shaft 603. The crushing wheel 604 is used to finely process the rock and soil so that the material can become fine and be discharged through the sieve hole to the discharge port 106, and is transported to the storage mechanism 7 for storage by the conveying mechanism provided at the discharge port 106. During use, the roughly processed rock and soil enters the crushing cylinder from the top opening of the shell through the feed port, and the driving shaft 601 drives the crushing wheel 604 through the crushing shaft 603 to crush the rock and soil. During the crushing process of the material, the smaller material after crushing can be discharged from the bottom of the shell through the sieve hole and transported to the storage mechanism 7 for storage.

[0034] The storage mechanism 7 includes a housing, a storage box, and a soil sample box. The housing is connected to the discharge port 106 of the fine crushing device 6 via a conveying pipeline. The conveying pipeline is used by a screw conveyor to transport the rock and soil into the housing. The housing has a storage trough inside, which is welded to the storage box. A cushion is placed at the bottom of the storage trough, and the soil sample box is placed in the storage trough and on top of the cushion. Each soil sample box is welded with a handle for easy removal. The soil sample box includes a box body and a box lid, which are threaded together. Each soil sample box is equipped with a sampling spoon to facilitate the removal of the crushed rock and soil during the test.

[0035] During operation, the rock and soil are first transported to the feed port 2 of the coarse crushing device by a conveyor belt, and are initially crushed by the crushing gear ring of the primary crushing structure 3. The rock and soil that meet the requirements are screened by the screening net 109 and then enter the fine crushing device 6. The rock and soil that do not pass through the screening net enter the secondary crushing structure 4 and are further crushed by the crushing disk 101 and the stone mill drive ring 103. The rock and soil that meet the requirements enter the fine crushing device 6. The fine crushing device 6 uses a crushing wheel to finely crush the rock and soil. After crushing, the smaller material can be discharged from the bottom of the shell through the sieve hole and transported to the storage mechanism 7 for storage; it can enter the crushing mechanism of the corresponding level across levels, effectively saving the occupation of the crushing space and improving the crushing efficiency, which greatly improves the crushing accuracy and quality.

Any technician familiar with the present invention may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
