Description

A high-efficiency grain dryer

technical field

The invention relates to the field of grain drying equipment, in particular to a high-efficiency grain drying machine.

Background technique

With the rapid progress and development of my country's economy and science and technology in recent years, my country's agriculture has also achieved rapid development, the level of agricultural automation has been greatly improved, and the production efficiency of grain has also achieved a great leap. However, in terms of grain drying and storage, the vast majority of farmers in our country still use the original drying method, which is not only inefficient, but also in the event of continuous rainy weather, the grain cannot be dried, which will lead to mold and germination of the grain, resulting in economic losses. Some farmers even put their grain on the road to dry, which has caused great disadvantages and hidden dangers to traffic safety. Therefore, it is imminent to carry out modern improvement on grain drying, and grain dryers have also emerged as the times require.

Currently commonly used dryers or drying methods mainly have the following problems:

1) The original drying is open-air exposure, which occupies a large area of production, is greatly affected by the weather, requires more manpower, and contains more impurities after drying;

2) The large-scale dryer is located outdoors, and the construction cost is high. It is not suitable to start when the dried grain is too small, and it cannot meet the drying needs of small and medium-sized farmers;

In order to solve the above problems, the applicant has designed a fully automatic grain dryer with a unique mechanical drying structure. The drying module includes a bucket-shaped baffle and a cone-shaped baffle. After dispersing with the cone-shaped baffle, the drying area in the same height of the drying bin is greatly improved, and the grains can also be fully dispersed. The grain is in contact with the hot air in the drying bin for a long time, which greatly improves the drying efficiency. The drying of the grain is very thorough and uniform, which greatly reduces the damage rate of the grain during the drying process. Studies have shown that if the bucket The redesign of the baffle and the conical baffle and the setting of creases on it can further disperse the grain fully and further improve the drying efficiency. In addition, the original design of the fully automatic grain dryer has a special ventilation duct on one side, so the structure is more complicated. , This application considers using a built-in heating plate instead of a hot air blower, making the dryer more mobile. In order to meet the drying requirements of different grains and control the circulation speed of grains in the dryer, a feeding funnel is added in this design, and a variety of feeding funnels with different apertures are configured for the user. The user can choose the appropriate aperture according to the drying needs. The feeding funnel is installed on the upper part of the drying shell, which makes the drying control more flexible.
