Description

Technical Field

[0001] This utility model belongs to the field of rock sampling technology, specifically a rock crushing and sampling device for geotechnical engineering. Background Technology

[0002] A rock crushing and sampling device is a piece of equipment used to collect rock samples in fields such as geological exploration, mineral resource assessment, and underground engineering exploration. Its function is to obtain raw samples from rock strata for further physical and chemical analysis, understand the properties of the rock and soil layers, and thus make more accurate engineering decisions. It breaks large rocks into small particles suitable for experimental analysis while preserving the original characteristics of the sample and avoiding contamination or changes in composition. During field exploration, samples are initially processed directly using the crushing and sampling device by placing the collected rocks into it for crushing. However, rock crushing and sampling devices are generally one-piece installations, and the crushing components cannot be replaced. When sampling rocks of different qualities, excessive crushing force may cause the original structural characteristics of the rock to be lost, affecting the accuracy of subsequent analysis. Especially for ultra-hard rocks such as granite and quartzite, ordinary crushing bottles will wear out severely, reducing efficiency, requiring the use of a jaw crusher. However, jaw crushers are bulky, not portable, and complex to use. Summary of the Invention

[0003] This invention provides a rock crushing and sampling device for geotechnical engineering, which facilitates the replacement of crushing components, improves efficiency, and is more convenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rock crushing and sampling device for geotechnical engineering, comprising a shell, a cover threadedly connected to the upper end of the shell, a drive motor disposed at the upper end of the cover, a crushing component movably connected to the bottom of the cover, a connecting component disposed at the lower end of the inner cavity of the shell, a support frame fixedly installed at the lower end of the outer wall of the shell, the crushing component comprising a crushing element, a fixing block disposed at the upper end of the crushing element, two springs fixedly installed in the inner cavity of the fixing block, a movable block fixedly installed at the ends of the two springs, a fixing plate disposed between the two movable blocks, and a tension spring elastically connected between the fixing plate and the movable blocks.

[0005] Preferably, the connecting assembly includes a sieve disc, a connecting block is fixedly installed on the top surface of the sieve disc, and a spring is connected between the sieve disc and the housing.

[0006] Preferably, the lower end of the drive motor is provided with a groove, the upper end of the crushing component is provided with a through groove, and the fixing plate and the through groove are movably connected.

[0007] Preferably, the lower end of the movable block is provided with a fixing groove, the movable block is configured as an inverted "L" shape, and the top of the fixing block is provided with a through hole.

[0008] Preferably, the top surface of the connecting block is arc-shaped, the bottom surface of the crushing component is arc-shaped, and the crushing component and the connecting block are in contact.

[0009] Preferably, the outer wall of the drive motor is provided with a fixing frame, and the fixing frame is fixedly connected to the top surface of the cover, and the lower end of the housing is provided as an inclined surface.

[0010] Preferably, the housing is made of stainless steel, and the fixing block is movably connected to the cover.

[0011] The beneficial effects of this utility model are:

[0012] 1) Through the cooperation of the fixed block and the moving block structure, the two moving blocks on both sides move in opposite directions, so that the moving blocks are released from the drive motor, and the new crushing component is replaced. The drive motor drives the crushing component to rotate, and the rotation of the crushing component crushes the rock, which avoids the loss of the original structural characteristics due to excessive crushing force, and the subsequent analysis of the rock is more accurate.

[0013] 2) Through the cooperation of the screen plate and connecting block, the bottom crushing rod of the crushing part abuts against the connecting block, causing the screen plate to move downward. When the crushing part no longer abuts against the connecting block, the second spring drives the screen plate to reset, preventing the crushed rock from clogging the screen holes. The screen plate classifies the crushed rock for subsequent analysis.

[0014] 3) Low maintenance cost: Only worn parts are replaced, extending the service life of the main body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides a rock crushing and sampling device for geotechnical engineering, including a shell 1, a cover 2 threadedly connected to the upper end of the shell 1, a drive motor 3 provided at the upper end of the cover 2, a crushing component 4 movably connected to the bottom of the cover 2, a connecting component 5 provided at the lower end of the inner cavity of the shell 1, and a support frame 6 fixedly installed at the lower end of the outer wall of the shell 1.

[0024] The crushing component 4 includes a crushing part 41. A fixing block 42 is provided at the upper end of the crushing part 41. Two springs 43 are fixedly installed at one end of the inner cavity of the fixing block 42. A moving block 44 is fixedly installed at the other end of each of the two springs 43. A fixing plate 45 is provided between the lower sections of the two moving blocks 44. A tension spring 46 connects the fixing plate 45 and the moving blocks 44.

[0025] The design of the housing 1 and crushing component 4 allows for the placement of sampled rocks within the inner cavity of the housing 1. The crushing component 4 is then replaced according to the type of rock. Holding the movable block 44, the two sides of the movable block 44 move back-to-back, disengaging it from the output shaft of the drive motor 3. Then, the fixing block 42, spring 43, and movable block 44 are moved downwards as a whole, replacing the crushing component 4 with a new one. After replacement, the crushing component 4 is placed back into the inner cavity of the housing 1, and then the cover 2 is rotated to connect it to the housing 1. The drive motor 3 is rotated, causing the crushing component 41 to rotate. The rotating crushing component 41 crushes the rock, and simultaneously, it abuts against the connecting component 5, causing the connecting component 5 to vibrate. This vibration of the connecting component 5 grades the crushed rock, facilitating subsequent analysis. A discharge port switch is located at the bottom of the housing 1.

[0026] like Figure 1 , Figure 5 As shown, the connecting component 5 includes a screen plate 51, a connecting block 52 is fixedly installed on the top surface of the screen plate 51, a spring 53 is connected between the screen plate 51 and the housing 1, the top surface of the connecting block 52 is arc-shaped, the bottom of the crushing component 41 is arc-shaped, and the crushing component 41 and the connecting block 52 abut against each other.

[0027] When the crusher 41 rotates to crush the rock, the bottom crushing rod of the crusher 41 abuts against the connecting block 52, causing the screen plate 51 to move downwards. When the crusher 41 no longer abuts against the connecting block 52, the second spring 53 drives the screen plate 51 to reset, preventing the crushed rock from clogging the screen holes of the screen plate 51 and hindering the proper grading of the crushed rock. Grading the rock facilitates subsequent rock analysis. In addition, the second spring 53 buffers the collision between the screen plate and the shell, reducing noise and extending the life of the components. Through the cooperation of the connecting block 52 and the crusher 41, and the arc-shaped design of the connecting block 52 and the crusher 41, the crusher 41 can abut against the connecting block 52 when rotating, requiring less effort during contact. This also enhances the crushing and compression efficiency of the rock, enabling the grading of the crushed rock for subsequent analysis.

[0028] like Figure 3 , Figure 4 As shown, the lower output shaft of the drive motor 3 has a groove, the upper end of the crushing part 41 has a through groove, the fixing plate 45 is movably connected to the through groove, the lower end of the moving block 44 is provided with a fixing groove, the moving block 44 is set in an inverted "L" shape, the top of the fixing block 42 is provided with a through hole for the drive shaft of the drive motor 3 to pass through, the outer wall of the drive motor 3 is provided with a fixing frame, and the fixing frame is fixedly connected to the top surface of the cover 2, the lower end of the housing 1 is set as an inclined surface, the housing 1 is made of stainless steel, and the fixing block 42 is movably connected to the cover 2.

[0029] By engaging the through slot at the upper end of the crusher 41 with the fixing plate 45, and then moving the fixing plate 45 with the tension spring 46, the crusher 41 is fixed. Subsequently, the horizontal portions above the two moving blocks 44 engage with the grooves of the drive motor 3, thus fixing the moving blocks 44. The fixing plate 45 is movably connected to the through slot at the upper end of the crusher 41. The opening of the fixing groove on the moving block 44 facilitates inserting fingers into the groove, making it easier for the two moving blocks 44 to move in opposite directions. The inverted "L" design of the moving block 44 allows for better engagement with the output shaft of the drive motor 3. The moving block 44 is movably connected to the fixing block 42, allowing the fixing block 42 to limit the movement of the moving block 44, ensuring smooth movement. The drive motor 3 is fixedly connected to the cover 2, thus securing the drive motor 3. A battery is located on the top of the cover 2, providing power to the drive motor 3, enabling normal outdoor use. The inclined design at the lower end of the shell 1 facilitates the removal of crushed and graded rocks, preventing them from accumulating at the bottom and becoming inaccessible. The shell 1 is made of stainless steel, free of harmful substances, corrosion-resistant, and suitable for outdoor rock and soil operations. Its smooth and hard surface facilitates cleaning and provides high mechanical strength and durability. The fixing block 42 is movably connected to the cover 2, engaging with it to connect the replaced crushing component 4, preventing loss of its original structural features due to excessive crushing force.

[0030] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
