Description

Technical Field

[0001] This utility model relates to a rock sampling device, specifically a mining double-blade rock cutting geological sampling machine. Background Technology

[0002] Rock sampling is a crucial step in mining operations. Its purpose is to understand the geological characteristics of ore deposits, the quality and distribution of the ore, and to provide a scientific basis for mineral resource evaluation, mine design, production management, and environmental protection. When encountering core samples that are too hard to be directly split, they are often first cut into thinner slices, and then further cut using a rock cutting geological sampling machine.

[0003] Currently, there are two types of rock cutting geological sampling machines used to deal with the above situations: one is a rock cutting geological sampling machine with a single blade, which can flexibly cut rock samples of any size, but its working efficiency is low and it requires multiple cuts to complete the rock sampling; the other is a rock cutting geological sampling machine with fixed double blades, which saves the number of rock cuts and greatly saves labor, but the spacing between the double blades on the rock cutting geological sampling machine is fixed, making it unable to cut rock samples with special size requirements, and its application range is narrow. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mining double-blade rock cutting geological sampling machine. The distance between the two blades can be adjusted to meet different size requirements of rock cutting and expand the range of applications. Compared with a single-blade sampling machine, it can reduce the number of cutting operations, save time and labor, and improve work efficiency.

[0005] To solve this technical problem, the present invention adopts the following technical solution:

[0020] Figure 2 This is a schematic diagram of the support arm structure of this utility model. Detailed Implementation

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, this utility model includes a support arm 7, a crossbar 6 is provided laterally at the middle of the rear side of the support arm 7, and a rotary motor 1 is provided at the rear end of the crossbar 6. The rotary motor 1 is provided with an emergency stop button 2 for starting and stopping the rotary motor 1. The rotary motor 1 and the crossbar 6 are connected by a connecting flange 5. The connecting flange 5 is provided with a shock-absorbing pad 3 for vibration damping, and the connecting flange 5 is fixed by bolts 4.

[0023] By providing a crossbar 6 on the rear side of the support arm 7, the drive motor 1 rotates the crossbar 6, causing the support arm 7 to rotate synchronously, realizing the angular rotation of the double blades from 0 degrees to 90 degrees, which is convenient for cutting rocks with different requirements and expands the scope of application.

[0024] The front side of the support arm 7 has two grooves, one above the other. The upper groove contains a longitudinally positioned upper lead screw 19, with a motor 18 at its top. An upper connecting block 17 is threaded onto the upper lead screw 19. An upper electric push rod 16 is laterally positioned on the front side of the upper connecting block 17, with a motor 15 at its front end and an upper saw blade 14 at its bottom. The lower groove contains a longitudinally positioned lower lead screw 20, with a motor 8 at its bottom. A lower connecting block 13 is threaded onto the lower lead screw 20. A lower electric push rod 9 is laterally positioned on the front side of the lower connecting block 13, with a motor 10 at its front end and a lower saw blade 12 at its top. The upper saw blade 14 corresponds to the lower saw blade 12.

[0025] By installing two vertically sliding saw blades on the support arm 7, the distance between the two blades can be adjusted according to cutting needs, meeting different size requirements for rock cutting and expanding its adaptability. Compared to a single-blade sampler, this device has two saw blades, which greatly reduces the number of cuts, saving time and effort and improving work efficiency. By installing an electric push rod on the saw blade, the depth of the saw blade's cutting action can be varied, further enhancing the device's applicability and making it more flexible.

[0026] The support arm 7 has slide rails in both the upper and lower grooves, located on the inner sidewalls of the grooves, which limit the movement of the upper connecting block 17 and the lower connecting block 13. Motor 18 and Motor 3 8 are both located on the outer side of the support arm 7, with Motor 18 at the top and Motor 3 8 at the bottom. Both the upper saw blade 14 and the lower saw blade 12 are equipped with coolant spray devices 11. By installing coolant spray devices 11 on both the upper and lower saw blades, the saw blades can be cooled during operation, extending their service life and improving cutting quality.

[0027] The method of using the double-blade rock cutting and geological sampling machine for mining described in this utility model is as follows:

[0028] Depending on the rock cutting requirements, this utility model can be installed on a mobile device (shovel loader or tracked mobile device) or a fixed device. Start the rotary motor 1; the crossbar 6 rotates, driving the support arm 7 to rotate. The support arm 7 then drives the two saw blades to adjust their angles synchronously. When the two saw blades have rotated to the appropriate position under the drive of the support arm 7, press the emergency stop button 2 to pause the rotary motor 1, allowing the support arm 7 to maintain its current angular position.

[0029] Next, adjust the positions of the two saw blades according to the rock cutting requirements: First, adjust the distance between the two saw blades. Start motor 18 to make the upper lead screw 19 rotate, driving the upper connecting block 17 to move up and down in the support arm 7, further driving the upper saw blade 14 to move up and down synchronously. Start motor 38 to make the lower lead screw 20 rotate, driving the lower connecting block 13 to move up and down in the support arm 7, further driving the lower saw blade 12 to move up and down synchronously, thus changing the distance between the two saw blades. Next, adjust the cutting depth of the two saw blades. Start motor 215 to make the upper saw blade 14 start rotating to cut. Start the upper electric push rod 16 to move motor 215 forward, driving the upper saw blade 14 to move forward, gradually deepening the cut of the rock. Start motor 410 to make the lower saw blade 12 start rotating to cut. Start the lower electric push rod 9 to move motor 410 forward, driving the lower saw blade 12 to move forward, gradually deepening the cut of the rock. During the cutting process of the upper and lower saw blades, the coolant spray device 11 is turned on to cool the saw blades.
