Description

[Detailed Description of the Invention] This invention relates to a safety device for a threshing machine that threshes grain stalks of rice, wheat, etc. by inserting the grain end into a handling barrel while holding and transporting grain stalks using a conveying device.

In a stationary threshing machine or a harvester with a threshing machine mounted on a traveling chassis, a supply stand for placing grain culms is installed on the insertion port side of the threshing machine's handling barrel, and the grain culm stock is sequentially supplied to the conveying device. However, since the conveyance device that clamps and transfers the stock of grain culms is installed outside the threshing machine, there is a risk that the threshing worker's hands may be drawn into the threshing machine, which is dangerous. For this reason, a clutch is provided to intermittent the drive of the threshing device so that the threshing operation is stopped when the threshing operation is not being performed, but sometimes people forget to operate this clutch while the threshing operation is interrupted.

This invention was constructed as follows in order to eliminate such inconveniences. In other words, a supply stand 3 is used to supply grain culms to a threshing machine 2 that threshes grain culms with a handling barrel while holding and transferring the grain culms with a conveying device 1.
This is a safety device for a threshing machine which can be freely switched between a used state and a non-used state, and is interlocked and connected so that the driving of the conveying device 1 is interrupted or interrupted by the switching operation of the feeding table 3.

By configuring this invention as described above, the invention has the following technical effects. That is,
When performing threshing work, the supply table 3 is put into use and the grain culm is placed thereon while supplying the stock of the grain culm to the conveying device 1 of the threshing machine 2 to perform the threshing work. If it is not present, it protrudes to the side of the threshing machine 2 and obstructs other operations, so it is stored in an unused state. Therefore, the conveying device 1 is driven only when the feeding stage 3 is in use. By interlocking, the dangerous conveying device 1 is not driven when the threshing operation is not performed, so there is no danger of the operator being accidentally caught in the feed chain 1 during operations other than the threshing operation.

Next, an embodiment of this invention will be explained with reference to the drawings.
This threshing machine 2 is mounted on a traveling chassis 4, and the traveling chassis 4 is equipped with a traveling device consisting of crawlers 5, a prime mover is provided in a driving section 6, and a loading platform 7 is provided.
When the threshing machine 2 is installed on the side so that it can be loaded and unloaded, and when the threshing machine 2 is unloaded, this loading platform 7
Load cargo onto the top and use it as a transport vehicle. A gear shift lever 8 for changing the traveling speed is located at the bottom of the traveling chassis 4.
A handle 9 provided on the upper part of the driving unit 6 is provided with a travel lever 10 for intermittent travel and a steering lever (not shown) for changing the direction of travel. Further, a support 11 protruding upward from the driving portion 6 is provided with a threshing machine 2.
A bag support rod 14 fixes the outlet 13 side of the grain barrel 12 through which the threshed grains are transferred and discharged, and supports the bag opening of the grain bag provided at the lower part of the outlet 13.
is fixed to the outside of the lower part of the driving part 6 so that the receiving tray 15 which receives and supports the lower part of the grain bag can be stored with its free end along the outside of the driving part 6 which has been rotated upward from the horizontal position. Pivot the base.

The threshing machine 2 has a built-in handling barrel 33, and is provided with a conveying device 1 on the driving unit 6 side of the traveling chassis 4 for pinching and transferring grain stalks between a feed chain 16 and a clamping rod 17.
A supply stand 3 on which grain culms are placed is provided on the side of the grain culm insertion port 18 to the threshing machine 2. This supply stand 3 has a base pivoted 21 to a bracket 19 protruding from the body of the threshing machine 2, a free end side supported by a support leg 20, and a free end side upwardly centered around the pivot part 21 of the base. It can be lifted up and stored along the body of the threshing machine 2 to put it out of use, or it can be put into use by keeping the mounting surface of the feeding table 3 substantially horizontal. 22 is a dust exhaust pipe for discharging dust generated within the threshing machine.

The driving force is transmitted from the driving unit 6 of the traveling chassis 4 to the threshing machine 2 through an output shaft 23 that protrudes to the side of the driving unit 6.
The belt 2 is connected to a pulley fixed to a pulley 26 fixed to an input shaft 25 protruding to the side of the body of the threshing machine 2.
Repeat by multiplying by 7. This power transmission is interrupted by a tension pulley 29 provided on a tension arm 28 rotatably pivoted to the body of the threshing machine 2.
The tension arm 28 and supply table 3 are connected to the rod 30 and the connecting tool 3.
1. Connect with tension spring 32. The connecting position of the rod 30 to the supply table 3 is the base end on the side of the threshing machine 2 from the pivot 21, so if the supply table 3 is put into use with the mounting surface approximately horizontal, the belt 27 is tensioned and the power is If the feeding table 3 is stored along the body of the threshing machine 2, the belt 27 will be loosened and power will not be transmitted.

In this embodiment, the movement of the feed table 3 between the used state and the non-used state is interlocked with the on/off of the drive of the threshing machine 2, but only the dangerous rotating feed chain located outside the body of the threshing machine 2 is connected. The on/off of the drive may be interlocked with the movement of the supply table.

In this way, the conveying device 1 is driven only when the loading surface of the supply table 3 is set substantially horizontally, that is, when it is in use, so that dangerous situations can be reduced.
