Description

[Detailed description of the invention] The present invention is such that the grain feeding hopper installed at the bottom of the elevator installed on the front side of the dryer body is switched alternately between the left side and the right side of the bottom of the elevator. This invention relates to improvements to a grain dryer that can be installed.

In the above-mentioned grain dryer, there is a grain supplying hopper attached to the left or right side of the lower part of the elevator. Since the front and rear directions are reversed, if the upper opening is enlarged so that it projects from the elevator to the front side when it is attached to the elevator, so that grains can be easily loaded into the hopper, Due to the limitations of the suction pipe that connects to the bottom of the elevator to suction and remove dust generated inside the elevator, the connection port of the hopper was placed deviated from the left and right sides of the elevator toward the main body of the dryer. In such cases, the hopper may interfere with the front of the dryer main body or various utensils installed on the front of the dryer, resulting in a problem that it becomes impossible to switch between the left side and the right side. Also, for this reason, the hopper must be formed symmetrically from front to back around the connection port, and the width from front to back must be small.
There is a problem that it becomes difficult to input the grains.

The present invention was made in order to solve these problems occurring with conventional means, and the hopper has a wider front and back width at its upper opening to facilitate the loading of grains. , even if the hopper connection port is installed on the left and right sides of the elevator and is offset in the front-back direction, the hopper can be installed on the left side and right side of the elevator alternately without any problem. The purpose is to provide a means.

In the present invention, as a means for achieving this purpose, a method is provided on the front side of the dryer main body in which a grain tank is installed, in which grains are loaded into the grain tank to be dried. In a grain dryer, a grain dryer is equipped with a lift, and hoppers for supplying grain can be alternately installed on the left side and right side of the lower part of a grain lifting tower of the lift. Openings for grain supply are installed symmetrically in the lower parts of both the left and right sides of the tower, and a connection gutter for the hopper is installed at the peripheral edge of each of the openings for grain supply. An assembly seat for removably assembling and supporting is installed, and the connecting gutter and opening/closing lid of the hopper are interchangeably attached to the assembly seats, and the hopper has two adjacent side walls. The other two side walls are vertical, and the other two side walls are inclined walls, and the bottom opening is located at a corner formed by the two vertical side walls, and the bottom opening is connected to the connection gutter. The present invention proposes a grain dryer characterized by being configured to be removable.
