Sample inserting equipment for deep-layer grains of grain granary

Abstract

The invention discloses sample inserting equipment for deep-layer grains of a grain granary. The equipment is formed to achieve the sample inserting mechanized operation of deep-layer grains of a large-sized grain granary. The equipment comprises a bracket mechanism, a sample inserting tube connecting and disconnecting mechanism and a control system, wherein the bracket mechanism is arranged on the top face of a grain stack in a manner that the bracket mechanism does not automatically sink, the sample inserting tube connecting and disconnecting mechanism is arranged in the bracket mechanism, forms a vertical rising and falling movement part and enables a sample inserting tube part to vertically sink into the grain stack and be withdrawn from the grain stack, and the control system controlsthe sample inserting tube connecting and disconnecting mechanism to achieve sinking and withdrawing work. The equipment is ingenious in design and more reasonable in control principle, structural configuration and operating mode, the mechanization of deep-layer sample inserting is achieved, and the condition that the former sample inserting operation needs the participation of multiple laborers and is high in labor intensity is changed. The equipment is very applicable to the sample inserting operation of deep-layer grain stacks of large-sized granaries (shallow circular granaries, large-diameter silos and vertical silos). The equipment can also be applied to the internal local set-point insecticide (aluminum phosphide) delivery, temperature measurement cable laying and the like of the large-sized granaries.

Description

technical field [0001] The invention belongs to grain sample extraction equipment, in particular to a deep-layer grain sampling equipment in a grain warehouse. The equipment is easy to operate and requires less maintenance. When used, it is used to realize the depth of the grain layer that is difficult to reach by manual sampling, saving energy. Manual and sampling operations are accurate and fast, and can be widely used in sampling inspection of various raw grains. Background technique [0002] Grain sampling equipment is a kind of equipment that obtains random grain samples of grain piles by inserting different grain layers of grain piles. According to different application environments, the structure types are divided into fixed-point type and manual-operated portable type. The fixed-point type is used to sample the grain in the vehicle before loading into the warehouse, and is usually located beside the vehicle weighing facility. [0003] At present, the sampling of dee...

Problems solved by technology

[0004] In the operation process of this method, the pressing and extraction of the sample pipe are all done by manpower, and the work intensity is high, and the connection of each steel pipe needs to be disassembled and assembled again, which is very cumbersome, and the whole sampling process requires a lot of work. Many people are involved, the manpower consumption is large, and the sampling efficiency is low

Moreover, as the depth increases, the sample rod will be subjected to a great pressure resistance, and multiple people need to use the pressure booster to simultaneously press down or rotate simultaneously. This process is difficult to advance. Difficult to operate by manpower alone
