Abstract

PURPOSE:To improve the extent of charging efficiency as well as to make work so easy by attaching a transfer spiral-built-in grain charging cylinder to one side in the point midway in a transferring gain collecting trough leading to an elevator in the lower part of a dryer. CONSTITUTION:A charger 29 provided with a transfer spiral 5 in a grain charging cylinder 6 is tightly attached to one side opening 31 of symmetrical side walls 8 of a dryer 1, and the tip is inserted into an opening 32 of a grain collecting trough 4 and fixed thereto. Then, a hull tank 34 is set up in a starting end of the charging cylinder 6. In this constitution, the transfer spiral 5 is driven, and unhulled rice is fed to this charging cylinder 6 from the hull tank 34. Accordingly, the unhulled rice is fed to the grain collecting trough 4 from the transfer spiral 5, and furthermore it is fed to an illustrated lifting gear by another transfer spiral 2, elevated and charged. With this constitution, charging work can be done without receiving any restriction as to an installation spot.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain loading device for a grain dryer.

Conventional technology Conventionally, in the grain loading device of a grain dryer, a paddy tank is attached to the lower part of a grain raising device that conveys the grains to the upper part, and the grains supplied into the paddy tank are transported to the upper part of the grain raising device. The grains flow into the device, are transported to the upper part by this grain raising device, and are loaded into the grain dryer, or are passed through a door from a paddy tank installed on the side of the grain dryer. It was a device in which grain was pushed through a gutter into a grain collection gutter.

Problems to be Solved by the Invention For example, in the grain loading operation, when grains are fed into a paddy tank installed on the side of a grain dryer, the grains flow from the paddy tank through a drain gutter into a grain collection gutter. The grains are supplied to the grain collecting trough, transferred to one side from the front and back by the transfer spiral in the grain collecting trough, and supplied into the grain hoisting device. However, it depends on the distance from the paddy tank to the grain collection gutter.

The angle at which the grains flow through the flow-down gutter becomes loose, resulting in a poor flow of grains and a significant drop in grain loading efficiency. In addition, in the case of a tensioning device with a paddy tank installed at the bottom of the grain raising device, the grain raising device is installed only in one place, which may make the tensioning work difficult due to installation in the workplace. there were.

Means for Solving the Problems This invention provides a method for collecting grains in the middle of a grain collecting trough (4) that receives grains flowing down from a drying chamber (1) and transports them to a grain raising device (3) by rotation of a transport spiral (2). The grain loading device of the grain dryer has a structure in which a grain loading tube (6) equipped with a transfer spiral (5) for transferring grains is visible on one side.

Effect of the Invention The grain tensioning work is carried out by supplying grains into a paddy tank provided above the grain tensioning cylinder (6), and then transferring the grains from this paddy tank into this grain tensioning cylinder (6). flows into this grain loading tube (6)
The grain is transferred by the inner transfer spiral (5) from the tip to the collecting trough (4).

Effects of the Invention According to this invention, by providing a grain loading tube (6) equipped with a transfer spiral (5) on one side of the grain collecting trough (4), grains are loaded by gravity. The grains are forcibly transferred and staked by the transfer spiral (5), thereby improving the pitching efficiency, and the provision of the grain pitching tube (6) improves the grain loading efficiency. The adaptability of grain loading has also been improved.
