Automatic feeding and discharging method for granular materials in horizontal warehouse

Abstract

The invention discloses an automatic feeding and discharging method for granular materials in horizontal warehouse. Mainly adopted equipment comprises a bucket elevator, a longitudinal screw conveyor, a horizontal screw conveyor and a corresponding controller, wherein the bucket elevator is used for conveying materials in a feeding hopper outside a warehouse into the warehouse during grain feeding, and then the longitudinal screw conveyor and the horizontal screw conveyor are matched closely to finish grain feeding and spreading; during grain discharging, a discharging gate valve in the warehouse is opened, the materials are conveyed to the outside of the warehouse through a pipeline and are elevated by the bucket elevator and sent to next procedure, and simultaneously, the longitudinal screw conveyor and the horizontal screw conveyor are matched for operation and convey the materials in each layer of the warehouse to a discharge opening in the warehouse, and grain discharging is finished. According to the method, reasonable selection and arrangement of the horizontal warehouse and the corresponding equipment are performed, so that mechanized automatic grain feeding and discharging operation of granular and powdery materials is convenient to achieve, labor cost can be reduced remarkably, and grain feeding and discharging working performance of the materials is improved.

Description

technical field [0001] The invention relates to the field of automatic loading and unloading of materials, and more specifically relates to a method for automatic loading and unloading of granular materials in flat warehouses. Background technique [0002] One-storey warehouse is the main warehouse type for storing grain and other materials in my country. The storage of materials in the flat warehouse is usually completed by means of moving equipment in and out of the warehouse. The common one-story warehouse bulk grain receiving equipment is mainly composed of belt conveyors, steering conveyors and bin loading machines, etc. The grain outbound equipment is mainly composed of grain raking machines, horizontal conveyors, and lifting conveyors. However, these mobile devices often have the disadvantages of large floor area, large auxiliary workload, and inability to realize centralized automatic control, and also need to build a special mechanical shed to place them; moreover,...

Problems solved by technology

However, these mobile devices often have the disadvantages of large area, large auxiliary workload, and inability to realize centralized automatic control, and also need to build a special mechanical shed to place them; moreover, they need to be moved frequently, It takes a lot of labor to adjust the equipment; in addition, the equipment needs to be operated on site, and a large amount of dust from the operation causes a bad working environment, difficult labor protection, and low efficiency

[0003] With the continuous development of the social economy, the gradual shortage of labor force, and the increasing requirements for the protection of the working environment of workers, this relatively extensive method of material entry and exit operations is increasingly unable to meet the requirements of the current economic development situation.
