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.

China is a large country for grain production and a large country for grain consumption, has great significance for making and storing grains, and is safe and socially stable in relation to China. At present, no portable equipment can complete the functions of deep sampling, deep aeration cooling, deep temperature and humidity measurement and deep pesticide application of grain piles. Based on the above problems, it is desirable to provide a portable multifunctional processing device with integrated functions.

The working principle of the invention is as follows:

the drill rod rack 4 can use the existing granary frame as the rack, or can be independently provided with the drill rod rack to be connected with the granary frame, after the guide cylinder 5 is fixed on the drill rod rack, the slipknot drill rods are connected in sections to form the drill rod 2, and are connected and combined as required, as shown in figure 3, the drill rod 21 is formed by connecting the drill bit drill rod 21, the sampling drill rod 22 and the ventilation drill rod 24, the drill bit drill rod 21 is not provided with a motor, but the first sleeve is internally provided with a temperature and humidity detector 232 and a ventilation hole 233.

When the device works, a drill point pricks a grain layer, the electric winch 10 is started, the traction rope downwards pulls the drill rod 2 to descend until the drill rod is completely pricked into the planned depth of the grain layer, temperature and humidity detection is firstly carried out through a temperature and humidity meter control and display system, and then an air blower control system is started to convey fresh air for ventilation and cooling.

After the work is finished, the lifting electric winch or the electric hoist is started, the traction rope upwards drags the drill rod 2 to be pulled out from the grain layer for reset, and the worker samples from the sampling drill rod 22. One drilling rod device in one process finishes three works of temperature and humidity detection, sampling and ventilation cooling, is simple and quick, can be additionally provided with a drilling rod slipknot according to needs, increases functions or increases the length of the drilling rod, and finishes grain layer treatment operation with more functions.
