Abstract

PURPOSE:To provide the title harvester so designed that a discharged air stream is blown against the rush foot in such a state as to catch said foot on a guide wall set up so as to cross the blowing direction of the air stream at a small angle, thereby blowing the rush in high efficiency leading to adequate disentanglement and removal of rush tailings. CONSTITUTION:Two kinds of equipment are provided: one is a gripping conveyor 5 to suspend, grip and carry rush after reaping; the other is a wind power- type sorter 6 so designed as to blow up the rush foot carried by the conveyor 5 from its side through a discharged air stream from a blower 6A to sort rush tailings off. And a guide wall 13 is set up on the blowing direction side of a blowing port 6a so as to cross said blowing direction at a small angle with planar view. A discharged air stream is blown against rush foot carried by the conveyor 5 from its side, and the rush foot is disentangled and blown up, thereby rush tailings are dropped off and blown off.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Industry] The present invention relates to a strawberry harvester that suspends and transports harvested strawberries and is equipped with a selection device for picking out waste straw.

[Conventional technology]

Conventionally, in this type of rush harvester, 1. A multi-stage rotating chain with locking claws is used to rotate the root side of the rush that is suspended and fed by a supporting conveyance device in a lateral direction perpendicular to the conveyance direction. While combing the waste to remove it, it was scooped up and placed on the deck in a horizontal position (Tokuko Sho 62).
-60043).

[Invention or problem to be solved]

In this case, the rotary chain with the locking pawl has a function of placing the grass in a sideways position while picking out the waste, but the locking pawl holds the base side of the grass. Since the grass is laid down horizontally so that it is forcibly scooped up, there are some spots where the grass is easily damaged, and the locking claw does not evenly contact all the grass being transported, so it is left unselected. There were some aspects where the removal of debris was not enough.

An object of the present invention is to provide a strawberry plant that can effectively remove debris without damaging the grass.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a clamping and conveying device that suspends and conveys the straw after harvesting, and
A wind-type sorting device is provided for sorting and selecting the waste straw by blowing from the side of the plant side with the air discharged from the blower device from the side of the clamping tube of the straw that is suspended and conveyed by the clamping and conveying device, and the blowing outlet A guide wall is erected at a location on the side of the air outlet in the air outlet direction so as to intersect with the air outlet direction at a small angle in plan view.

[For production]

According to the above configuration, the straw that is being transported in a hanging manner is blown from the side toward the plant side from the clamping point, so that the plant side of the rush is blown up from being unsorted.
Any debris stuck in this will fall out and be blown away by the emitted wind.

In this case, the collecting wall installed at the side of the blowing direction of the air outlet of the blowing device restricts the free swinging of the stem side of the rushes being blown up, and keeps them in a state where they are caught by the guide wall. The air discharged from the blower 1 is forced to run strongly along the surface of the guide wall, and this air is concentrated on the side of the rush plant, making it possible to strongly and reliably apply the wind.

〔Effect of the invention〕

As described above, in the present invention, by using wind force to blow up the plant side from the clamping point of the straw that is being transported by hanging, it is possible to remove the straw with less damage such as scratches on the straw. In particular, when blowing the discharge wind, it is important to keep the side of the rice plant caught by a guide wall that is erected so that it intersects at a small angle with the direction of the discharge wind. It is possible to efficiently blow the blast air onto the grass to give it sufficient cleaning and blowing action, and to reliably remove the waste grass.
