An intelligent sample collection device

Abstract

The invention discloses an intelligent sample collecting device which comprises a machine frame. The machine frame is provided with a feed inlet. A rotatable rotating disc mechanism and multiple sample storage barrels used for collecting samples are arranged in a collecting cavity formed by the machine frame. The sample storage barrels are hung on the rotating disc mechanism. Each sample storage barrel is provided with a hinged barrel cover and an induction locking mechanism used for locking the barrel cover. The hinged position of the barrel cover is provided with an elastic part so that the barrel cover can bounce upwards to be opened when not locked. The feed inlet is provided with a liftable weighing mechanism. The weighing mechanism is provided with an induction unlocking assembly matched with the induction locking mechanism. When the rotating disc mechanism drives the sample storage barrels to rotate to the position below the feed inlet, the weighing mechanism raises to lift up the sample storage barrels, so that the induction locking mechanism induces an unlocking signal of the induction unlocking assembly to open the barrel covers for sample connection and weighing operation. The intelligent sample collecting device has the advantages that the structure is simple and compact, the intelligence degree is high, sample collection and transfer safety is high, sample collection quality precision is high, working efficiency is high, and the production cost is low.

Description

technical field [0001] The invention mainly relates to equipment for collecting and processing material samples, and in particular to an intelligent sample collecting device. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and analysis process. The purpose of coal sampling an...

Problems solved by technology

[0005] (1) The safety of the storage barrel of the existing sample collection device is low. For example, some of the seals are sealed by screw caps, which can be opened and closed manually. The samples are easily changed manually during the transfer process, which may cause sample fraud. And then also seriously affect the follow-up laboratory results and production and operation

At the same time, it is easy to cause sample leakage during transshipment, which affects the quality and accuracy of the sample, and then seriously affects the subsequent test results and production and operation.

[0006] (2) The storage barrel of the existing sample collection device needs to be additionally equipped with an independent opening / closing barrel device and a power source for opening / closing the barrel in order to realize timely opening during sample collection and timely closing after sample collection, which makes the sample storage barrel And the sample collection device has a complex structure, takes up a lot of space, and has high cost of use

And part of the opening / closing device has a complex structure, which is prone to errors or failures during operation, and even causes damage to the entire sample collection device in serious cases

At the same time, opening / closing the barrel requires an additional time process, which to a certain extent restricts the operation time of storage and sampling, and affects the efficiency of the collection and production operation

[0007] (3) With the existing sample collection device, when the sample storage barrel is fixed on the turntable, it cannot be positioned and fixed accurately and quickly, and displacement between the sample storage barrel and the turntable is prone to occur

This makes it impossible for the sample storage barrel to be precisely positioned directly below the material inlet when the sample storage barrel is driven by the turntable to rotate the inlet for collection.

This will cause the sample to fall sideways when it is unloaded from the inlet, and the samples cannot be collected in the sample storage bucket, resulting in sample loss

The loss of the sample reduces the quality accuracy of the sample, which seriously affects the subsequent test results and production and operation of the sample.

At the same time, the residual material falls into the sample collection device, which is easy to cause mechanical failure, and often needs to be cleaned, which consumes manpower

Moreover, the storage bucket cannot be quickly positioned and fixed when it is fixed, which also greatly affects the work efficiency and improves the labor intensity

[0008] (4) The existing sample collection device, the rotary positioning of the turntable is not accurate

When the sample storage barrel is rotated and stopped by the turntable, the rotation inertia of the turntable will cause the sample storage barrel to not be accurately positioned directly below the material inlet, and a series of technical problems caused by the above-mentioned samples falling sideways will also appear.

[0009] (5) The intelligence level of the existing sample collection device is not high. When the sample storage barrels enter and leave the sample collection device, manual transfer is required. After the collection operation is completed, manpower is required to take each sample storage barrel out of the sample collection device one by one, which consumes a lot of human energy, leads to high labor costs, and is prone to safety accidents

[0010] (6) The existing sample collection device needs to manually take and place the sample barrels one by one, so that the existing sample collection device must be shut down before the pick-and-place operation, and the shutdown takes a long time, which makes the existing sample collection device Low production efficiency seriously affects the production and operation of enterprises

At the same time, due to the manual operation of taking and placing the sample barrels, it is easy for the samples to be changed manually during the process of taking, placing and transferring, which is prone to sample fraud, which in turn seriously affects the subsequent test results and production and operation of the samples.
