Grain feeding and distributing conveying device and control system thereof

Abstract

The invention discloses a grain feeding and distributing conveying device. The device comprises a polygon material distributing device and a plurality of material distributing grooves communicating with the material distributing device; an opening used for feeding is formed in the upper end of the material distributing device, and the plurality of material distributing grooves are uniformly distributed at the side part of the material distributing device; and a plurality of material outlets communicating with the material distributing grooves are uniformly distributed in the side part of the material distributing device, the material distributing device is provided with gates used for opening and closing the material outlets, and a plurality of discharge openings capable of being opened and closed are formed in the bottoms of the material distributing grooves at intervals along the length direction of the material distributing grooves. The discharge time of each material falling pointis controlled through opening and closing of the gates, a current transformer is installed on a power line of a driving motor of a lifting machine and the current transformer is connected to a pulse watt hour meter, so that the size of the material pile of each material falling point can be accurately controlled; and the uniform distribution of impurities is realized, the layering and grading condition is reduced, the qualitative change of the permeability of the grain pile is realized, so that the whole grain can be uniformly ventilated and cooled under the existing ventilation condition.

Description

technical field [0001] The invention relates to the technical field of warehousing and logistics, and in particular, relates to a grain warehousing distribution conveying device and a control system thereof. Background technique [0002] my country is a large agricultural country with a long history of food production and storage. According to a large number of cultural relics and historical research unearthed in China in the past fifty years, China’s primitive agriculture was enlightened in the late Paleolithic Age and developed in the New Era (about 1 year ago). million years or so). The storage of grain is the continuation of agricultural cultivation, and storage technology develops along with the development of agriculture. After entering the new era, with the development of primitive agriculture, agricultural production has formed a certain scale, and grain surplus has gradually developed from grain processing to storage. [0003] Grain storage refers to the storage an...

Problems solved by technology

[0005] At present, all shallow round silos in China use conveying machinery to carry out grain entry operations from the top of the silo. However, since there is only one fixed entrance, it is basically located in the center of the granary. Because the materials are scattered freely from top to bottom, the size, weight, and Shapes, impurities, etc. form natural layers and grades, and are compactly pressed together. Generally speaking, full grain grains are relatively concentrated around the granary, while most impurities, broken grains and dust are relatively concentrated in the center of the granary, forming a cylinder. As a result, it cannot be evenly ventilated, and the moisture and temperature cannot be effectively and evenly adjusted. There are storage safety hazards such as heating, mold, germination, and deterioration of materials.
