Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a clamping and conveying device that clamps and hangs the core side portion of cut straw grass and conveys it to the rear, and also provides a clamping and conveying device that clamps and suspends the core end portion of the cut straw grass and conveys it to the rear. A cross-feeding locking and conveying device is provided that acts on the root-side portion of the rush to feed it laterally, and a sideways blow-up and selection action is applied to the root-side portion of the rush that is sent by the cross-feeding locking and conveying device. This is a grass harvester equipped with a number of wind power devices, and by using the wind power device, the grass is not combed up as forcefully as compared to one that uses locking claws, so it does not damage the stems. The present invention relates to a rice grass harvester having a characteristic structure such that the selection wind enters the rice grass and performs the selection action evenly, so that the selection performance is high.

[Conventional technology]

Conventionally, in this type of rush harvester, as proposed in, for example, Japanese Patent Application No. 175585/1985, the root side portion of the rush that is suspended and supported by the clamping and conveying device is laterally locked and conveyed. A horizontal feed locking conveyance device is provided,
The terminal end of this cross-feed locking and conveying device was set in front of the discharge port of the wind power device, and the portion on the side of the rush plant was affected by the air discharged from the discharge port.

[Problems to be Solved by the Invention] However, even with such a configuration, since the lateral feed locking and conveying device locks and conveys, when it comes near the discharge port of the wind power device, Under the influence of the discharge wind, the stock end side portion was pushed out to the discharge wind action area and escaped not in the lateral direction but rather in the front and back direction, and a sufficient selection effect was not applied.

Therefore, on the conveyance path side of the horizontal feed locking and conveying device, there is a fixed structure that prevents the straw grass locked in the horizontal feed locking and conveying device from being pulled out from the locking mechanism and guides it to the discharge port. Although it is possible to provide guide rods, ■If the volume of the grass fed by the horizontal feed locking conveyance device increases, it may cause clogging, or conversely, the guide rods should be installed at intervals to prevent clogging. In this case, the guide function cannot be fully performed, and the problem remains that ◎As the rushes are sent along this guide rod, the rushes are damaged by the contact resistance.

An object of the present invention is to provide a device that can sufficiently perform the selection action by providing a rational mechanism in consideration of the above-mentioned circumstances.

(Means for Solving the Problems) The characteristic configuration according to the present invention is such that a drive rotation guide body is provided on the opposite side of the lateral feed locking and conveying device across the conveyance path of the lateral feed locking and conveying device, and The present invention is configured such that the stationary conveyance device and the driving rotation guide body guide the stock side portion to the discharge wind area of the wind power device, and its effects are as follows.

[For production]

In other words, near the discharge port of the wind power device, the lateral feed locking conveyance device and the drive rotation guide body are conveying the rush in a state surrounding the plant side portion, and the rotational force of the drive rotation guide body The portion on the side of the base of the rice plant can be forcibly pushed into the discharge wind area of the wind power device.

C Effects of the Invention] Therefore, when the sideways locking and conveying device is used alone, the stock side portion that escapes due to the discharge wind is not received by the driving rotation guide body, and by forcibly pushing it in with this rotation body,
You can definitely make the wind of choice work. In addition, since the driving rotation guide body performs a forceful pushing action, even if the volume of the stem side of the conveyed rush increases, it can be pushed into the discharge wind area, and since it is a rotating body, the fixed guide body Compared to rods, there is less frictional contact, and the good sorting function of the sorting air can be effectively utilized.
