Abstract

PURPOSE:To prevent the transfer of remained grains by disposing a grain fall- preventing member on the carrying end side of a carrying screw in a grain carrying cylinder. CONSTITUTION:When the grains in a grain tank 1 are discharged, the releasing opening 2 of a grain carrying cylinder is placed above an objective position and a carrying screw 4 is driven. The grains are released out while passing through above a grain fall-preventing member 5. When the carrying work is completed and subsequently a grain carrying cylinder 3 is returned to a normal position, grains remained in the grain carrying cylinder 3 are transferred with the vibrations of the frame. But since the transfer of the grains are stopped near the releasing opening 2 with the grain fall-preventing member, the grains are not fallen from the releasing opening 2 outside the frame.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a grain discharge device that can be used in combines and harvesters.

Prior Art The conventional grain ejection 11% device does not include a conveying grain blocking member in the grain spiral cylinder on the conveying end side of the conveying spiral.
When the combine harvester resumes work after the grain tank has finished discharging grains, the vibration of one machine causes the grains remaining in the grain transport tube to fall loosely from the discharge 11 to the outside, causing a spillage phenomenon. was.

Problems to be Solved by the Invention The present invention relates to an improvement on the conventional technology in which the two-way 71S l
``The purpose is to prevent the phenomenon of paddy spilling from the j as much as possible.

Means for Solving the Problem The present invention takes the following technical means in order to achieve the object mentioned in 1-1. That is, there is a grain conveying cylinder 3 whose starting end is connected to the grain tank 1 and whose terminal end is open to the outside, and a conveying spiral which is mounted on the internal shaft of the grain conveying cylinder 3. 4, and a grain spill 1Ir111 provided in the grain conveying tube 3 on the conveying end side of the conveying spiral 4.
This is a grain conveying device composed of a member 5.

Functions/Effects When carrying out the filled grain in the grain tank 1 as a result of the reaping and threshing work to the outside of the machine (for example, to the bed of a truck), the grain transport cylinder 3 is rotated vertically and horizontally around its base. Move the discharge port 2 to the target position (truck bed) by repeating the movement.
It is positioned to one side and the conveying spiral 4 is driven.

Then, the grains in the grain tank 1 reach the grain transport cylinder 3 from the grain lifting cylinder 6, and are transported by the transport spiral 4 toward the discharge port 2.

In this way, the grains are discharged from the discharge port 2 onto the loading platform H of the truck and loaded thereon.

At this time, the grains pass through one side of the grain spill prevention member 5 and are released from the release [12].

Complete the grain removal work as described in -1- above.

The grain conveying cylinder 3 is returned to the normal standby position and the reaping and threshing work is restarted.

At this time, the grains remaining in the grain transport cylinder 3 move with the vibration of the machine body and reach near the discharge port 2, but the grains remaining in the grain transport tube 3 move further to the grain spill prevention IL member 5. This prevents the liquid from spilling out of the machine from the discharge port 2.

The example grain tank 1 is mounted on a vehicle chassis 7, and is configured to be filled with grains transported from a threshing machine 8.

6 is a grain cylinder.

The grain conveying tube 3 has a conveying spiral 4 therein, and its starting end communicates with the grain tank 1 via the fried grain fW6.

At the terminal end, there is provided an opening/1 end 12.

The grain spill prevention member 5 is made of an elastic material in the form of a plate.

It is attached to the lower part of the terminal end of the grain conveying cylinder 3.

Since it is configured as shown in I-, grain spillage prevention 1#-
, when the conveying spiral 4 is driven to transport the grains, the member 5 is pressed by the conveyed grains and is elastically deformed, so that it is pushed down.

Then, the grain spillage prevention member 5 enters the raised state when the conveying action is stopped for a second time, and can prevent the movement of the remaining grains.
