Description

Technical Field

[0001] The utility model relates to the field of geological technologies, in particular to a precise rock sample grinding device for geological structures. Background Art

[0002] Traditionally, during geological exploration, when it is necessary to test geological isotopes and conduct elemental analysis, rock samples need to be ground into powders of about 200 meshes. Generally, a sample crusher is required to crush rock samples. For qualitative sampling, it can generally meet the requirements. However, for geological structures with relatively small scales such as stromatolites, the sizes of such rock samples are small, and the operation of the sample crusher is not delicate enough to achieve delicate stratified sampling and crushing. There is a large amount of sample waste, which is not conducive to geological exploration research. At the same time, it is easy for operators to get injured when holding rock samples by hand, which is not conducive to the smooth progress of sampling work. Content of the Utility Model

[0003] The purpose of the utility model is to provide a precise rock sample grinding device for geological structures.

[0004] The utility model is implemented by the following technical solutions: A precise rock sample grinding device for geological structures, which includes a dust-proof cover, a base, a clamping device, a support rod, a motor, a grinding head, and a lead screw.

[0005] The base is arranged inside the dust-proof cover.

[0006] Two vertically arranged support rods are fixed to the top end of the base. A cross beam is fixed between the top ends of the two support rods. A vertically arranged screw sleeve is fixed to the cross beam. The lead screw vertically arranged is screwed inside the screw sleeve. The top end of the lead screw penetrates through the dust-proof cover and is fixedly connected to a handle outside the dust-proof cover. The bottom end of the lead screw is rotatably connected to a guide rod. Guide holes matching the two support rods are formed on both sides of the guide rod. The guide rod is slidably arranged between the two support rods through the guide holes.

[0007] The motor is fixed to the guide rod, and the grinding head is fixed to the output end of the motor.

[0008] The clamping device is fixed to the base between the two support rods.

[0009] Further, the support rod is provided with scale lines.

[0010] Further, the clamping device includes two symmetrically arranged clamping components.

[0011] The clamping assembly includes a clamping head, a limiting plate, a screw rod, a spring, and a rotating handle. The screw rod is screwed to one of the support rods. One end of the screw rod close to the grinding head is rotatably connected to the limiting plate. The bottom end of the limiting plate is slidably connected to a chute opened on the base.

[0021] The base 2 is provided inside the dust-proof cover 1. The function of the dust-proof cover 1 is to ensure that the problem of dust emission is reduced during the process of processing rock samples. At the same time, due to the small size of the stromatolite rock samples or special precious rock samples, under the action of the dust-proof cover 1, the dust powder can be intercepted inside the dust-proof cover 1, which is convenient for subsequent recovery, reduces the loss of rock samples, and the dust-proof cover 1 adopts a transparent dust-proof cover 1, which is convenient for observing the sampling situation inside the dust-proof cover 1.

[0022] Two vertically arranged support rods 3 are fixed at the top of the base 2. The support rods 3 are provided with scale lines 4. The function of the scale lines 4 is to indirectly ensure the grinding amount of the grinding head 5 downward. A cross beam 6 is fixed between the tops of the two support rods 3. A vertically arranged screw sleeve 7 is fixed on the cross beam 6. A vertically arranged lead screw 8 is screwed inside the screw sleeve 7. The top of the lead screw 8 passes through the dust-proof cover 1 and is fixedly connected with a handle 9 outside the dust-proof cover 1. The bottom end of the lead screw 8 is rotatably connected with a guide rod 10. Guide holes 11 matching the two support rods 3 are opened on both sides of the guide rod 10. The guide rod 10 is slidably arranged between the two support rods 3 through the guide holes 11. A motor 12 is fixed on the guide rod 10, and a grinding head 5 is fixed at the output end of the motor 12.

[0023] The specific operation process is as follows: During the process of the grinding head 5 processing the rock sample, by rotating the handle 9, the lead screw 8 is driven to rotate. During the rotation of the lead screw 8, the guide rod 10 is driven to move up and down along the support rod 3. It is convenient to observe through the dust-proof cover 1. According to the layered thickness of the rock sample, the descending amount of the grinding head 5 is controlled, so that precise layered sampling can be achieved, reducing the confusion between each layer of rock samples and at the same time reducing the waste of rock samples.

[0024] A clamping device 13 is fixed on the base 2 between the two support rods 3. The rock sample can be clamped and fixed through the clamping device 13, which solves the problem of injury caused by holding the rock sample by hand during the sampling process. At the same time, in cooperation with the clamping device 13 and the dust-proof cover 1, the problems of work environmental pollution and personal health are solved.

[0025] The clamping device 13 includes two symmetrically arranged clamping assemblies 14, the clamping assembly 14 includes a clamping head 14.1, a limit plate 14.2, a screw 14.3, a spring 14.4, and a turning handle 14.5. The screw 14.3 is screwed to one of the support rods 3, and the end of the screw 14.3 close to the grinding head 5 is rotatably connected to the limit plate 14.2. The bottom end of the limit plate 14.2 is slidably connected to the slide groove 15 provided on the base 2, and the slide groove 15 limits the moving direction of the limit plate 14.2. The clamping head 14.1 is fixed on one side of the limit plate 14.2 close to the grinding head 5. The clamping heads 14.1 on the two clamping assemblies 14 clamp the rock sample. The screw 14.3 is fixed to ensure the stability of the rock sample during the sampling process. The other end of the screw 14.3 passes through the dust cover 1 and is fixedly connected to the handle 14.5 outside the dust cover 1. The screw 14.3 is rotated through the dust cover 1 to achieve the clamping and loosening operation of the rock sample by the clamping head 14.1, thereby ensuring the surrounding working environment. A spring 14.4 is provided on the screw 14.3 between the support rod 3 and the limit plate 14.2. Specifically, by rotating the two handles 14.5, the corresponding screw 14.3 is driven to rotate. During the rotation of the screw 14.3, the limit plate 14.2 is driven to move, so that the two clamping heads 14.1 clamp and fix the rock sample.

[0026] A collecting trough 16 is movably provided on the base 2 before the two clamping heads 14.1. The function of the collecting trough 16 is to collect the rock samples ground by the grinding head 5. After the sampling is completed, the dust cover 1 is provided with a switch door 18. The switch door 18 is opened to take out the collecting trough 16, and then the rock sample powder is sent for inspection. The above operation is performed after each layer is sampled until the required layers are sampled.
