Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention mainly relates to a dry store or a country elevator in which pre-dried grains such as rice are preliminarily dried in a storage bin close to natural drying during temporary storage. And a grain receipt storage device.

Conventional technology Conventionally, as shown in Japanese Utility Model Laid-Open No. 49-37446, a technology of providing a bottom conveyor and a ventilation path on a storage bin installation surface, and a technology of providing a bottom conveyor and a ventilation path under the storage bin installation location are known. is there.

[Problem to be Solved by the Invention] In the conventional technology, in a structure in which a bottom conveyor or the like is provided on the ground, it is necessary to form the grain input bottom of the storage bin high, and in a structure in which the bottom conveyor or the like is provided in the basement, There are problems such as extremely high costs and management costs. In particular, in equipment where the upper opening edge of the receiving hopper is flush with the ground surface and the loading of grains can be easily performed, by providing a loading elevator and a discharging elevator between the receiving hopper and the storage bin, at least the lower end of the discharging elevator is provided. Is installed lower than the bottom conveyor, there is a problem that providing the bottom conveyor below the ground cannot easily simplify the underground structure and reduce the equipment cost. In addition, even if the swivel floor at the bottom of the grain input of the storage bin is raised by providing a bottom conveyor etc. on the ground, the interval between the sweep floor and the outlet of the ventilation path will be large, so the width of the storage bin left and right will be enlarged. Considering the advantage that it is easy to secure the storage capacity and to easily send the air from the blowout section uniformly to the entire sweep floor, if a bottom conveyor is provided on the ground surface below the sweep floor, During the work to be blown, there is a problem that the worker cannot easily approach the bottom conveyor.

`` Means for solving the problem '' Accordingly, the present invention provides a storage bin for temporarily storing received grains to be loaded into a receiving hopper, and a grain transport path in which a bottom conveyor for taking out grains in the storage bin is provided. In the grain receiving and storing apparatus for providing a blower passage for blowing air to a blower chamber at the bottom of a storage bin, a receiving port in which the outlet opening portion of the blower chamber is formed as a grain carry-out path, and is formed substantially flush with a receiving grain carry-in work surface. A storage bin and a bottom conveyor installation surface are formed at substantially the same height as the opening edge of the hopper upper surface, and a lower end of a loading elevator that inputs grains from the receiving hopper to the storage bin via a top conveyor, and the bottom conveyor feeding end. The lower end of the discharge elevator to be connected is disposed in an extension of the underground space in which the receiving hopper is provided.

"Operation" Therefore, a part of the ventilation chamber is used to form a grain discharge path and a bottom conveyor is provided, which simplifies the bottom conveyor installation structure and makes it easier for workers to approach the bottom conveyor during ventilation. In addition to reducing the installation cost of the bottom conveyor and improving the operability around the bottom conveyor, the storage bin and the bottom conveyor can be easily manufactured while achieving uniform airflow into the storage bin and securing the storage capacity. Since the height of the installation surface and the height of the upper opening edge of the receiving hopper match, the bin, the conveyor and the hopper can be installed with reference to the work surface on the ground for loading the receiving grain, and the underground space in which the receiving hopper is installed is also provided. Since the lower part of the loading / unloading elevator and the discharge lifting / lowering machine is arranged by expansion, the underground space required for receiving and storing the cargo can be reduced, and equipment and management costs can be reduced. In addition, it is possible to simplify the installation structure and management work by bringing the lifting and lowering elevators close to each other, and connect each lifting and lowering machine to both the bottom conveyor and the top conveyor to perform both input and discharge of grain respectively. Can be easily configured to improve the loading / unloading function of the received and stored grains and the handling operability.
