[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0023] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a geological sample crushing device provided by an embodiment of the utility model includes a grinding barrel 2, a grinding cone 3 is rotatably installed inside the grinding barrel 2, a motor 6 is fixedly installed on the upper part of the grinding barrel 2, and the grinding cone 3 is driven by the motor 6 to perform a rotational grinding action. A crushing channel 10 is formed between the grinding barrel 2 and the grinding cone 3. The crushing channel 10 is gradually set, and the upper channel transverse diameter of the crushing channel 10 is larger than the lower channel transverse diameter of the crushing channel 10. The crushing channel 10 receives the geological sample and performs a layer-by-layer decreasing crushing work. A lifting support 1 is provided at the lower part of the grinding barrel 2, and the lifting support 1 includes a material discharge seat 101. A material discharge channel 102 is opened inside the material discharge seat 101, and the material discharge channel 102 is connected with the lower output end of the crushing channel 10. An electric push rod 103 is fixedly installed inside the material discharge seat 101, and the output end of the electric push rod 103 is rotatably connected to the lower part of the grinding cone 3, and the crushing channel 10 is driven by the electric push rod 103 to perform a gap adjustment action.

[0025] In the above-mentioned geological sample crushing device, the geological sample to be crushed is placed in the upper part of the crushing channel 10. At this time, the electric push rod 103 is in a retracted state, and the gap of the crushing channel 10 is relatively small to accommodate larger geological samples. Then the motor 6 is started to drive the grinding cone 3 to rotate inside the grinding barrel 2. Since the crushing channel 10 is gradually set, the lateral diameter of the upper channel is larger than the lateral diameter of the lower channel. The geological sample is subjected to the rotational extrusion and friction of the grinding cone 3 in the crushing channel 10, and is crushed layer by layer from the top. During the crushing process, the sample continues to move downward and passes through the gradually shrinking crushing channel 10 to finally achieve the crushing of the sample. When the geological sample passes through the crushing channel 10 and is crushed into sufficiently small particles, they will enter the unloading channel 102 along the lower output end of the crushing channel 10. The unloading channel 102 is connected with the lower output end of the crushing channel 10, so that the crushed sample can be discharged smoothly. When geological samples of different diameters need to be crushed, the gap of the crushing channel 10 can be adjusted by the electric push rod 103. The electric push rod 103 extends or contracts, driving the grinding cone 3 to move up and down, thereby changing the gap size of the crushing channel 10. In this way, the device can adapt to geological samples of different diameters and improve crushing efficiency.

[0026] In summary, the geological sample crushing device realizes the functions of rapid crushing of geological samples and adapting to samples of different diameters through the gradual crushing channel 10 and the electric push rod 103 adjusting the gap, thereby improving the crushing efficiency.

[0027] In this embodiment, the inner wall of the grinding barrel 2 is provided with a second guide pattern 9, and the outer wall of the grinding cone 3 is provided with a first guide pattern 8. The first guide pattern 8 of the grinding cone 3 cooperates with the motor 6 and the second guide pattern 9 of the grinding barrel 2 to perform a guiding transmission action.

[0028] By introducing the first guide lines 8 and the second guide lines 9, the crushing effect and efficiency of the crushing device are further enhanced. Specifically, when the motor 6 drives the grinding cone 3 to rotate inside the grinding barrel 2, the first guide lines 8 and the second guide lines 9 cooperate with each other to form a guiding transmission effect. This effect can guide the geological sample to be more evenly distributed in the crushing channel 10, avoiding blockage or accumulation of the sample during the crushing process. At the same time, the guiding transmission effect can also make the geological sample more evenly ground and squeezed in the crushing channel 10, thereby improving the crushing effect.

[0029] In addition, by adjusting the shape and arrangement of the first guide lines 8 and the second guide lines 9, precise control of the crushing particle size can also be achieved. For example, when a finer crushing particle size is required, a more dense and fine arrangement of the lines can be used to increase the contact area and friction between the grinding cone 3 and the geological sample, thereby obtaining a finer crushing particle size. On the contrary, when a coarser crushing particle size is required, a more sparse and coarse arrangement of the lines can be used to reduce the contact area and friction between the grinding cone 3 and the geological sample, thereby obtaining a coarser crushing particle size.

[0030] In this embodiment, a support frame 4 is fixedly installed on the upper part of the grinding barrel 2, a mounting seat 5 is fixedly connected to the upper part of the support frame 4, and a motor 6 is fixedly installed on the lower part of the mounting seat 5. A driving rod 7 is fixedly connected to the output end of the motor 6, and limiting grooves are provided on both sides of the driving rod 7. The driving rod 7 is vertically slidably connected to the upper part of the grinding cone 3.

[0031] The support frame 4 is fixedly mounted on the upper part of the grinding barrel 2, and is used to support and fix the mounting seat 5. The mounting seat 5 is fixed to the lower part of the support frame 4 by bolts or other connection methods, providing a stable installation foundation for the motor 6. The motor 6 is fixedly connected to the driving rod 7 through the output end, and the driving rod 7 is provided with limited grooves on both sides, which are vertically slidably connected to the upper part of the grinding cone 3. In this way, when the motor 6 is started, the driving rod 7 will drive the grinding cone 3 to rotate inside the grinding barrel 2, thereby achieving the crushing of the geological sample. And when the electric push rod 103 drives the grinding cone 3 to rise and fall, it does not affect the work of the motor 6.

[0032] The setting of the limit groove can ensure the stable connection and sliding between the driving rod 7 and the grinding cone 3, and avoid shaking or falling off during the crushing process. At the same time, the limit groove can also limit and guide the rotation of the grinding cone 3 to a certain extent, so that it can perform crushing work more stably. This structural design not only improves the stability and reliability of the crushing device, but also prolongs its service life and maintenance cycle.

[0033] In this embodiment, a plurality of support columns 105 are fixedly connected to the lower portion of the material discharge seat 101 , and a same chassis 104 is fixedly connected to the lower portion of the plurality of support columns 105 . A material receiving box 106 for collecting crushed geological samples is placed at the center of the chassis 104 .

[0034] The material discharging seat 101 is fixedly connected to the chassis 104 through a number of support columns 105, which are evenly distributed at the bottom of the material discharging seat 101, providing stable support for the device. The chassis 104 serves as the base of the entire device, carrying and fixing the support columns 105, so that the entire crushing device can be placed on the ground more stably. In the center of the chassis 104, a material receiving box 106 for collecting crushed geological samples is placed. In this way, when the crushed samples are discharged from the material discharging channel 102, they will directly fall into the material receiving box 106, which is convenient for users to carry out subsequent sample processing and analysis.

[0035] The working principle of this utility model:

[0036] When in use, the geological sample to be crushed is placed in the upper part of the crushing channel 10. At this time, the electric push rod 103 is in a retracted state, and the gap of the crushing channel 10 is relatively small to accommodate larger geological samples. Then the motor 6 is started to drive the grinding cone 3 to rotate inside the grinding barrel 2. Since the crushing channel 10 is gradually set, the lateral diameter of the upper channel is larger than the lateral diameter of the lower channel. The geological sample is subjected to the rotational extrusion and friction of the grinding cone 3 in the crushing channel 10, and is crushed layer by layer from the top. During the crushing process, the sample continues to move downward and passes through the gradually shrinking crushing channel 10 to finally achieve the crushing of the sample. When the geological sample passes through the crushing channel 10 and is crushed into sufficiently small particles, they will enter the unloading channel 102 along the lower output end of the crushing channel 10. The unloading channel 102 is connected with the lower output end of the crushing channel 10, so that the crushed sample can be discharged smoothly. When geological samples of different diameters need to be crushed, the gap of the crushing channel 10 can be adjusted by the electric push rod 103. The electric push rod 103 extends or contracts, driving the grinding cone 3 to move up and down, thereby changing the gap size of the crushing channel 10. In this way, the device can adapt to geological samples of different diameters and improve crushing efficiency.
