Description
Technical Field
The application relates to the technical field of grain drying, and particularly discloses a grain drying and discharging device.
Background
Grain drying is an important link after grain harvesting, and is also an important condition for grain safe storage in summer. In order to reduce field loss and ensure the quality of harvested grains, the state requires timely harvesting, and most of the harvested grains have high moisture. The south rice and the north autumn corn have high water content and are difficult to air manually due to low temperature in autumn, so that the mechanization of grain drying is very important.
The selection and configuration of the grain drying tower are based on the relative movement direction of grains and air flow, the dryer can be divided into cross flow, mixed flow, concurrent flow, countercurrent flow, concurrent countercurrent flow, mixed countercurrent flow, concurrent flow and the like, after grains are dried, the grains can be stored only after being cooled, but when the grain drying tower is cooled at present, the grains are easily cooled at the highest speed, so that the grains are crushed, and the crushed grains are easily polluted by microorganisms and the like in the storage process, so that the storage quality of the grains is influenced.
Disclosure of Invention
The invention aims to solve the problem that grains are easy to be cooled at the highest speed when the traditional grain drying tower cools the grains, so that the grains are crushed.
In order to achieve the purpose, the basic scheme of the invention provides a grain drying and discharging device which comprises a grain drying assembly and a grain cooling assembly, wherein the grain drying assembly comprises a drying tower and a plurality of grain lifting mechanisms communicated with the top of the drying tower, one side of the drying tower is communicated with a hot air mechanism, the grain lifting assembly comprises a lifting barrel and a lifting belt installed in the lifting barrel, a lifting motor used for providing power for the lifting belt is arranged on the lifting barrel, the hot air mechanism comprises a boiler, a heat exchanger communicated with the boiler, a hot air motor communicated with the heat exchanger and a hot air pipe communicated with the heat exchanger, and the hot air pipe is also communicated with the drying tower;
the grain cooling component comprises a cooling bin communicated with the drying tower and an air cooler communicated with the bottom surface of the cooling bin, the top of the cooling bin is provided with a plurality of air outlets, one of them air outlet and drying tower bottom one side intercommunication, the bottom surface is equipped with the grain conveyer belt in the drying tower, grain conveyer belt one end is located the cooling bin, cooling bin bottom surface intercommunication has the spout, it is equipped with the baffle to slide in the spout, spout one side is equipped with a plurality of discharge gates, the spout bottom surface is equipped with the function pipe, the intercommunication has a plurality of water sacs on the function pipe, baffle below rigid coupling has a plurality of push rods that are used for extrudeing the water sac, it is equipped with the cooling tube to promote bucket inner wall spiral, be equipped with on the boiler and hold boiler heating and can the confined hot-water tank, the one end and the hot-water tank intercommunication of function pipe, the other end and the cooling tube intercommunication of function pipe, be equipped with the check valve that is used for controlling.
The principle and effect of this basic scheme lie in:
1. the grain lifting mechanism can continuously convey the grains on the bottom surface to the top of the drying tower, and then the grains enter the drying tower to be dried; the hot air mechanism continuously provides mixed flow hot air for the drying tower, and can effectively dry grains.
2. After grain is dried, can fall into the grain conveyer belt surface that sets up in the drying tower bottom surface along with the gravity of self, then control grain conveyer belt work, make treat in the refrigerated grain can get into the cooling storehouse, with the air-cooler work of cooling storehouse bottom surface intercommunication, make cold wind upwards flow from the cooling storehouse bottom surface, in this in-process, the low temperature grain of cold air elder generation contact lower part, absorb the heat in the grain when upwards moving, cold air temperature risees gradually, the rapid cooling of grain when can avoid cold wind and the contact of upper strata hot grain like this, the counter-current cooling both can improve the cooling effect of cooling zone, can also protect the quality of grain not influenced.
