Gate-type automobile sampling machine

Abstract

A gate-type automobile sampling machine comprises a rail in the front-back direction. The portal cart with the drive is arranged on the rail in the front-back direction in a rolling fit manner, and rails in the left-right direction are installed on an upper cross beam of the portal cart. A sampling trolley with drive is arranged on the rail in the left-right direction in a rolling fit manner, a sampling head is arranged on the sampling trolley, a primary belt conveyor is also arranged on the sampling machine, a hammer crusher is arranged behind the primary belt conveyor, a division machine isarranged behind the hammer crusher, the sample of the division machine enters the blanking chute to be weighed, and the sample weighed by the blanking chute enters the sample barrel of the sample collector. The sampling machine solves the problem of dust raising in the sampling process, the sampling head is sensitive to detect when meeting resistance, and the sample collector is reliable in operation after being upgraded and optimized.

Description

technical field [0001] The invention relates to sampling equipment for coal and mine vehicle transportation, in particular to a door-type vehicle sampling machine, which belongs to the technical field of mechanical equipment. Background technique [0002] In production enterprises that use coal and mines as raw materials, such as thermal power plants and coking plants, strict inspections of incoming coal are required, and scientific and rigorous sampling is required before inspections. Sampling machine is the equipment to complete the sampling of incoming materials from automobiles. It has been widely used in materials entering the factory, such as the coal sampling workshop for automobiles entering the factory disclosed in Chinese Patent No. 2015206663094, and a beltless automatic mechanization of automobiles disclosed in 201910351312 The sampling system has described the overall composition and technical scheme of the automobile sampling machine. The current automobile sam...

Problems solved by technology

The current automobile sampling machine has the following defects in use: First, the dust is relatively large, and there are mainly three sources of dust, 1. The dust generated by the large drop in the direction of the discharge hopper and the discharge of the belt, 2. The discharge of the hammer crusher Dust generated; 3. Dust generated when the distance between the lower end of the feeding chute and the mouth of the sample bucket is relatively large when the sample collector is fed, which is similar to the lockable information-based collection of samples in a sample bucket in Chinese Patent No. 2015207180560 adopted by the applicant Because the lock is installed on the upper part of the barrel cover, the distance is relatively large

The dust is too large to meet the current environmental protection requirements. In order to meet the environmental protection requirements, the manufacturer has to seal the surroundings of the car sampling machine. For example, China Patent No. 2015206663094 adopts a sampling workshop, which can solve the dust problem. Installing corresponding doors for entry and exit will require additional investment, which will also bring great inconvenience to the entry and exit of the car, and it is not easy to monitor; second, there are hard impurities in the incoming materials of the car. This kind of hard object will generate a lot of resistance, which will lead to equipment damage or rollover accidents. The current protection device for hard objects has a complicated structure and a lagging response. It is often sensed only when damage occurs. ; The third is the problem of the sample collector. In order to prevent artificial cheating, the current sample collector adopts a lockable informational sample collector for a sample bucket in Chinese Patent No. 2015207180560. The problems are mainly manifested in 1. Large transmission error , especially cumulative errors are prone to occur, resulting in inaccurate positioning of the sample barrel, feeding errors and locking failures occur from time to time; 2. The locking actuator of the sample barrel needs to set two strokes, and the locking mechanism is complicated; It is found that the IC card is set on the side of the sample barrel and is prone to damage during operation
