Description

Integrated drill rod equipment for processing grain layer of granary

Technical Field

The method has the main characteristics of small occupied area and great advantage for areas with scarce land capital. But as the storehouse type of grain storage, also have its fatal weakness, it is the grain layer extremely high, from 20 meters to 50 meters all have the silo of different height. The grain layer is very high, the stretching surface of the silo to the air is large, the sun radiation heat is strong, the danger difference of the upper layer can reach about 10 meters, the southern area of China is deeper, the grain is easy to heat after being heated, once the deep heating phenomenon of the grain occurs, if the ventilation and cooling treatment is not good, the silo is finally turned over to be the final end, and huge loss is brought to enterprises and society.

The conventional portable ventilation and cooling equipment for the granary mainly comprises a metal ventilation pipe, a handheld pipe pressing machine, a ventilation fan, a distribution box and the like. The metal ventilation pipe is pressed into the grain pile by about 1 m per section through a handheld pipe pressing machine, the ventilation pipe is pressed into the grain pile by about 5-6 m deep in a butt joint mode, and then the deep part of the grain pile is cooled through a ventilation fan. Problems with such devices: the handheld pipe pressing machine is propelled in a grain stack in a powerful spiral mode, and a spiral drill bit at the front part can damage grains. In addition, the ventilation pipe of the equipment is deepest and can only reach 5-6 meters deep part of the grain pile, and the ventilation and cooling effects can not be realized at the lower part of the grain pile with the grain layer height of about 20 meters.

The existing grain sampling equipment such as a sampling sampler is difficult to sample for grain piles with the depth of more than 4 meters, and particularly, sampling cannot be carried out on deep grain piles with the depth of about 20 meters.
