DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power transmitting device for a grain hopper which is mounted on a tractor carrier and moves.

[0002]

2. Description of the Related Art There have been various proposals for an apparatus in which a grain conveyor is provided in a grain hopper.

[0003] For example, Japanese Utility Model Laid-Open No. 3-76822 (Prior Art 1) provides a rotatable connection device that is a base portion of a grain-feeding conveyer, a range that cannot be reached in a flexible range of the grain-feeding conveyer, a place that cannot be reached in time, and the like. In this case, the degree of freedom is improved to improve the workability.

[0004] Japanese Utility Model Laid-Open No. 5-54421 (Prior Art 2) relates to a container for transporting cereals. The configuration is an apparatus for rotating a plurality of conveyor shafts from a rotating shaft of one motor via a number of belts and pulleys.

[0005]

However, the device described in the prior art 1 has a problem that two motors must be used to drive a screw conveyor and a grain feeding conveyor in a grain hopper. There was a point.

In the case where a plurality of rotating shafts are to be rotated by one motor as described in Prior Art 2,
It is driven by providing a transmission mechanism and a counter shaft for a number of belts and pulleys, and has the drawback that the device becomes complicated and an unnecessary transmission mechanism protrudes outside the hopper, and the protruding portion hinders movement. . Further, pulleys and belts have relatively low power transmission, which causes a problem that the transmission efficiency is reduced due to deterioration of the belt, and a problem that the entire apparatus becomes large.

According to the present invention, two conveyors can be reliably and stably driven by a single driving force source, and the discharge port of the grain feeding conveyor can be rotated in a horizontal direction to easily cope with any place. An object of the present invention is to obtain a compact grain hopper power transmission device.

[0008]

[Means for Solving the Problems] To solve the problems,
A single motor with a rotating shaft facing downward in the vertical direction is fixed to the front outer wall, which is the discharge side of the grain hopper, which can store the grains inside and has a screw conveyor at the bottom. A plurality of transmission portions are provided on an extension shaft below the provided rotation shaft, a first transmission portion is provided in the support case and connected to a shaft of a horizontal screw conveyor, and a second transmission portion is provided on an inner wall of the rotating case. And connected to the horizontal conveyor shaft connecting shaft, and the horizontal conveyor shaft connecting shaft is detachably connected to the receiving shaft of the conveyor unit and rotates. The case is rotatable with respect to the support case, so that the discharge port at the tip of the conveyor unit for grain feeding can be rotated in the horizontal direction to easily change the grain discharge direction, so that the discharge can be freely adjusted. Power transmission device for grain hopper To draft.

A single motor having a rotating shaft directed downward in the vertical direction is fixed to a front outer wall which is a discharge side of a grain hopper in which a grain can be stored and a screw conveyor is provided at a lower portion. A plurality of transmission units are provided on an extension shaft below a rotation shaft disposed in a vertical direction, the first transmission unit is provided in a support case and connected to a shaft of a horizontal screw conveyor, and a second transmission unit is provided.

For grain feeding with spring con It proposes a power transmission device of grain hopper, characterized in that the outlet of the conveyer tip can horizontally easily change the grain discharge direction is rotated can freely discharge adjustment.

[0010]

The motor fixed to the grain hopper is arranged so that its rotation axis is in the vertical direction. Therefore, the motor is fixed to the screw conveyor shaft and the extension part of the vertical rotation axis via two transmission boxes. The conveyor connection shaft for grain feeding can be connected.

When the motor is driven, the rotating shaft rotates, and the rotating force is transmitted to the screw conveyor shaft and the grain feeding conveyor connecting shaft via the transmission box.
