Description

[Detailed description of the invention] The present invention is a feeder that is connected to a hopper opening provided at the bottom of the elevator of a grain dryer and is used to streamline the work of loading grain into the interior of the grain dryer. This invention relates to improvements to a staked hopper with a grain spiral.

The process of drying grains harvested in the field using a combine harvester using a grain dryer involves transporting the grains from the field using a truck or other transport vehicle to the workshop or barn where the grain dryer is installed. First, grain is poured into the grain hopper installed at the bottom of the elevator of the dryer, and the grain is loaded into the inside of the machine by the operation of the elevator. The tensioning hopper is usually formed with a width much narrower than the width of the left and right sides of the loading platform of the transport vehicle, so the grain transported by the transport vehicle can be dumped into the work area, and from there it can be used for tensioning the elevator. I'm trying to transfer it to Hopper.

For this reason, the staking hopper installed at the hopper opening of the elevator should be made wider and has a larger capacity than the left and right widths of the carrier's loading platform. A large amount of grain received in the hopper is sequentially fed into the hopper mouth of the elevator using a grain feeding spiral installed at the bottom of the hopper. A means has been developed to do so.

However, when a wide tensioning hopper is attached to the hopper opening of the elevator of a grain dryer, the tensioning when assembled to the elevator depends on the installation condition of the grain dryer installed in the workshop or barn. A problem arises in which the longitudinal direction of the hopper, that is, the protruding direction, is not compatible with the access path, which is a space formed in the workshop (or barn) in order to allow the transport vehicle to enter the workshop.

As a countermeasure to this problem, as described in Japanese Utility Model Publication No. 45-14269, a screw conveyor connected to the rotary shaft for frying grains through a universal joint shaft is installed at the inlet of the elevator. One possibility is to connect the tip end to the outlet of the tensioning hopper, but even with that, the possible bending range of the universal joint shaft is only about 30 degrees.
The relative position of the tensioning hopper with respect to the elevator cannot be changed significantly, and moreover, the tensioning hopper must be moved away from the elevator by the length of the screw conveyor connected to the elevator. Another issue arises that narrows it down.

The present invention was made in order to solve these problems that have arisen with conventional means.The present invention has been made in order to solve these problems that have arisen with conventional means. When the tensioning hopper is brought close to the elevator, the longitudinal direction of the tensioning hopper can be easily changed to a direction parallel to the front surface of the elevator and a direction perpendicular to the front surface of the elevator so that it can be assembled and installed. The purpose is to adapt it to the approach road of vehicles.

For this purpose, the present invention is equipped with a tensioning hopper formed to have a width corresponding to the left and right widths of the loading platform of the transport vehicle, on a machine frame that is formed separately from the elevator of the grain dryer. A grain feeding device for transferring grains in the wide direction is provided at the bottom of the inner cavity of the tensioning hopper, and a grain feeding device is provided at one end side of the tensioning hopper in the wide direction. A discharge port is provided on the terminal side in the grain transfer direction, and a discharge tube is attached to the discharge port, which is inserted into the hopper port frame provided with the hopper port at the bottom of the elevator. is closed with an end wall 71, a discharge port is provided on the bottom side so that it can be freely opened and closed, and a connection port that is removably connected to the opening of the hopper spout frame is provided on the side side.
