Description

Technical Field

[0001] The invention relates to the technical field of geological prospecting operations, and in particular to a crushing sampling device for geological prospecting operations. Background Art

[0002] The crushing sampling device for geological prospecting operations is an important equipment in geological exploration and mineral resource assessment. The crushing sampling device for geological prospecting operations is usually composed of a sampling mechanism, a crushing mechanism, a transmission mechanism, a control mechanism and other auxiliary components. When in use, the operator first places the device on the geological material where samples need to be collected, and starts the device through the control panel, and the sampling mechanism starts working. During the sampling process, the sampling tool or sampling pliers may separate the sample from the ore or rock by rotation or impact. The collected sample is sent to the crushing mechanism, and the crushing mechanism performs preliminary crushing treatment on the sample. During the crushing process, the crushing blade, crushing hammer or crushing wheel and other components rotate or impact the sample under the drive of the motor to break it into smaller particles. The crushed sample is sent to the collection container through the conveying mechanism. The crushing sampling device for geological prospecting operations is widely used in mines, geological exploration teams, scientific research institutions and other fields.

[0003] For example, the Chinese patent "A Drilling Sampling Device for Geological Exploration" with announcement number CN210071375U includes a support frame, a hydraulic rod and a drilling motor, the hydraulic rod is fixedly mounted on the top of the support frame, the output end of the hydraulic rod is fixedly welded with the support frame, the drilling motor is fixedly mounted inside the support frame, and the output end of the drilling motor is fixedly mounted with a drive shaft, the end of the drive shaft is fixedly welded with a mounting frame 2, and an exhaust fan is fixedly mounted inside the mounting frame 2, the output end of the exhaust fan is extended out of the mounting frame 2 through an output pipe, and a sampling collection bottle is spirally mounted on the mounting frame 2, the center of the end face of the mounting frame 2 opposite to the drive shaft is fixedly welded with a drilling steel pipe with a hollow structure inside, and the input end of the exhaust fan is arranged in the drilling hole through an extraction pipe At the inner end of the steel pipe, a through hole is opened at the end of the drilled steel pipe corresponding to the extraction pipe, support legs of a spirally sheathed telescopic structure are fixedly installed at both ends of the bottom of the support frame, and a spirit level is set on both sides of the hydraulic rod corresponding to the support frame. A scale mark rod of a sheathed telescopic structure is set at the bottom of the support frame corresponding to the drilled steel pipe. After the scale mark rod is extended, the length of the scale mark rod is on the same horizontal line with the end of the drilled steel pipe. The scale mark rod is arranged with at least four groups of casing structures with gradually decreasing inner diameters. A through hole is opened at the end of the casing in a closed state, and a limiting retaining ring is set at the end of the through hole of the other group of casings through the end of the casing. An output port in a shape is fixedly installed on the side of the second mounting frame corresponding to the end of the output pipe, and the input end of the sampling collection bottle and the end of the output port are spirally installed.

[0004] Although the above-mentioned prior art can realize geological sampling, in actual use, on the one hand, the sampling box is difficult to replace, and different working scenes usually require the use of sampling devices of different sizes, resulting in the need to disassemble and assemble the entire fixed structure each time the sampling box is replaced, thereby increasing the workload of the operator.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention can quickly fix the arc-shaped sampling box through the clamping plate and the limit plate. Before sampling, the leveling of the base has been completed. At this time, the two arc-shaped sampling boxes are placed on the top of the base, and the servo motor is turned on to drive the output shaft of the servo motor to rotate the screw rod, and the connecting plate is driven to move toward each other in the slide groove through the thread on the outside of the screw rod. At the same time, the clamping plate on the connecting plate moves together until the side of the clamping plate contacts and squeezes the arc-shaped sampling box, and then the sampling mechanism is installed on the base. When the arc-shaped sampling box needs to be replaced, the second bolt is rotated to move the second bolt upward in the second threaded hole through the external thread until the second bolt is disengaged from the second threaded hole. At this time, the clamping plate is removed from the connecting plate, and then the arc-shaped sampling box is removed from the base and the samples are collected and processed. Finally, the new arc-shaped sampling box is put back on the base and clamped and fixed, thereby simplifying the disassembly and assembly steps of the arc-shaped sampling box.

[0018] (2) The present invention can quickly level the base through the threaded rod and the bubble level. Before sampling, the first hydraulic telescopic device is first turned on to extend the telescopic end of the first hydraulic telescopic device. The extension of the telescopic end of the first hydraulic telescopic device drives the connecting seat to move outward in the storage groove. At the same time, the damper and the threaded rod move together until the connecting seat is moved to a suitable position. At this time, the sampling device is placed in the sampling area, and the operator observes the bubble position inside the bubble level. If the bubble position is offset, the operator rotates the appropriate threaded rod to move the threaded rod downward inside the connecting seat through the external thread. At the same time, the lower end of the threaded rod rotates on the damper until the base is adjusted to a horizontal state through the connecting seat and the first hydraulic telescopic device. At this time, the bubble is in the center position inside the bubble level, thereby improving the stability of the sampling device during the sampling process.

[0019] (3) The present invention can move the connecting seat to the storage groove through the first hydraulic telescopic device and the storage groove. When the sampling operation is completed, the entire sampling device is first lifted by an external tool. At this time, the threaded rod is rotated to make the threaded rod move upward inside the connecting seat through the external thread until the rubber pad at the lower end of the damper is moved to a suitable position. At this time, the first hydraulic telescopic device is turned on to make the telescopic end of the first hydraulic telescopic device contract. The contraction of the telescopic end of the first hydraulic telescopic device drives the connecting seat to move toward the storage groove. At the same time, the damper and the threaded rod move together until the connecting seat is moved to the inside of the storage groove. At this time, the sampling device is placed in a suitable position, which reduces the space occupied by the sampling device when it is idle, thereby improving the overall space utilization of the sampling device.
