Technical Field
The invention relates to the technical field of temperature measurement, in particular to a granary temperature measurement device.
Background
A grain bin is a building or facility dedicated to storing grains, and other agricultural products. As an indispensable ring in agricultural production, the existence of the granary has important significance for guaranteeing grain supply and food safety. Grain bins are often provided with a certain building structure and special design in order to provide an optimal storage environment. They are usually made up of strong walls, roofs and floors to protect the stored grains from the external environment. The interior of the grain bin is typically equipped with a ventilation system and temperature and humidity control equipment to ensure that the stored grain maintains a suitable temperature and humidity level. In addition, the granary can provide facilities for preventing insects, mice and the like according to the requirement so as to prevent grains from being damaged by the insects.
Measuring the temperature of the grain bin helps to control and maintain the quality of the grain. Grains are susceptible to temperature during storage, and if the temperature is too high or too low, the grains can become moldy, insect pests can grow, and the nutritive value can be lost. Measures such as ventilation, cooling or heating can be taken in time by measuring the temperature of the grain bin so as to maintain the stable state of the grain.
However, since the granary is usually huge and the depth in the granary is very deep, the temperature of different areas in the granary cannot be accurately measured when the temperature is measured, and therefore, in the process of storing grains, the condition that the grains are mildewed due to untimely temperature control can occur.

Fifthly, rotating the rotating rod 51 to enable the first part 31 to move inwards of the inserted link 2, wherein the first part 31 can drive the second part 32 to move inwards of the inserted link 2 until the first part is in the position shown in fig. 3 under the action of friction between the chute 8 and the second part 32 and the pressure of grains outside the inserted link 2; during this process, it may not be possible to bring the third portion 33 completely into the insert rod 2 at a time, so the fourth and fifth steps may be repeated several times, so that it is ensured that the third portion 33 also enters the insert rod 2;
And sixthly, the inserted rod 2 is pulled out of the grain, the collecting part 14 is taken down from the inserted rod 2, the grain condition in the collecting part 14 is observed and known, and the grain state is comprehensively evaluated according to the measured temperature data to determine whether ventilation and other operations are needed.
When the temperature sensor 6 is positioned in the chute 8, the temperature sensor 6 is in a relatively stable state, and the temperature value fluctuation is small; when the temperature sensor 6 contacts with the grain, the temperature sensor 6 detects the temperature of the grain, so that the temperature can fluctuate widely compared with the prior temperature, and the temperature sensor 6 can be judged to be in place. Meanwhile, in this embodiment, one end of the rotating rod 51 passes out from the operating end 22, a hand wheel is fixed at one end of the rotating rod 51 which passes out of the inserting rod 2, scales can be respectively engraved on the hand wheel and the inserting end, an operator is reminded of what position the measuring rod 3 is located by the scales, and meanwhile, the rotating angle or the number of turns in each operation is determined by the scales, so that the temperature sensor 6 can be ensured to be in contact with grains, and meanwhile, the third part 33 can be ensured to be stored into the inserting rod 2.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
