Automatic grain sampler

Abstract

The invention relates to the field of grain sampling technical equipment, in particular to an automatic grain sampler, having a telescopic pillar fixed on a ground. A telescopic cross arm that may horizontally rock around the telescopic pillar is arranged at the top end of the telescopic pillar; a vertical hydraulic cylinder is fixedly connected to the top end of the telescopic end of the telescopic cross arm; a needle rack is arranged on a piston rod of the vertical hydraulic cylinder; a sampling needle is arranged on the needle rack. The automatic grain sampler is characterized in that the top end of the vertical hydraulic cylinder is connected with the tail end of the sampling needle, the center of the sampling needle is provided with a grain suction passage, the lateral side of the sampling needle is provided with a side hole perpendicular to the grain suction passage, a vacuum unit is arranged at the bottom of the vertical hydraulic cylinder, and grain is sucked into the grain suction passage from the side hole and fed into a chemical test apparatus. The automatic grain sampler is simple in structure, ingenious in design and high in working efficiency, and is suitable for directly sampling and testing grain; a needle tip protector is provided, so that the sampling needle gains longer life; the automatic grain sampler has a good application prospect.

Description

technical field [0001] The invention relates to the technical equipment field of grain sampling, in particular to an automatic grain sampling machine. Background technique [0002] The grain cutting machine is a kind of equipment for sampling and spot-checking the grain quality of the grain pile by inserting the grain pile. In practical application, the technology of the grain cutting machine is mature, and there are many types of products for different working environments. At present, most of the grain cutting machines have been Gradually adopt electrical control, and gradually increase the degree of automation. However, in the actual application process, the following problems often appear: [0003] 1. In the process of transporting grain, when the transport vehicle passes the cutting machine, due to the large size of the transport vehicle itself, in order to facilitate the insertion and sampling, it is often necessary to manually direct the transport vehicle to stop at ...

Problems solved by technology

[0003] 1. In the process of transporting grain, when the transport vehicle passes the cutting machine, due to the large size of the transport vehicle itself, in order to facilitate the insertion and sampling, it is often necessary to manually direct the transport vehicle to stop at a specific position, which consumes manpower, delays working time, and affects Productivity;

[0004] 2. During the insertion and sampling process of the cutting head, it often happens that the cutting head touches the bottom of the carriage due to improper operation of the staff or the grain pile is too shallow, which damages the cutting head, and even causes the cutting head to break in serious cases.
