Description: TECHNICAL FIELD The present invention relates to a strawberry harvester provided with a selection device for selecting and scraping straw grass while suspending, supporting and transporting the straw grass after cutting.

[Conventional technology]

In this type of straw harvester, conventionally, the root side of the straw which is suspended and supported by a holding and conveying device is sent by a rotary chain with a plurality of locking claws that rotates in a lateral direction orthogonal to the conveying direction. And select the waste straw grass,
It had a configuration in which it was picked up in a hooked state and laid down on its side and placed on the collection deck (Japanese Patent Publication No. 62-60043).
Issue).

[Problems to be Solved by the Invention]

In this case, only the rotary chain with the locking claws has a feature of selecting the waste grasses and placing the straw grasses in a horizontal position in a horizontal posture. Since the posture is such that it is laid sideways so that it can be forcibly scooped up by picking up with, there is a point that the strawberries are easily damaged, and the locking claws do not touch all the strawberries that are transported, so it is left unselected. However, there were some aspects where the removal of waste straw grass was not sufficient.

An object of the present invention is to select a proper mechanism as a selection device, to smoothly remove waste straw grass while suppressing damage to the straw grass itself, and to mow the planted straw grass as expected. Is in the point of providing.

[Means for Solving the Problems]

The characteristic configuration according to the present invention is that a holding and conveying device that holds and conveys the upper part of the straw grass after being raised is provided, and that a mowing device that cuts the root side portion of the strawberries held by the holding and conveying device is provided. And, in the part of the root side of the straw grass that is being held by the holding and conveying device and being cut by the reaping device, a wind type selection device that blows out the wind emitted from the blower from the lateral side and selects the waste straw grass is provided. There is a certain point, and a point is provided with a lifting and conveying device that locks the root side portion of the straw grass blown up by the discharge wind and guides the straw grass sideways to the upper side and conveys it to the conveyance path. It is as follows.

[Action]

(B) As shown in FIG. 2, the wind blown from the blower (6A) is blown to the root side of the straw grass suspended by the holding and conveying device, and the waste wind causes the dust to be scraped. Can be blown off and separated.

(B) Moreover, as shown in FIG. 1, the timing of blowing the discharge air is set while the strawberries are suspended by the holding and conveying device (5) and held by the cutting device (3) while being cut. Since it is set, the root side part of the once cut straw grass and waste straw grass is blown off immediately by the blowing wind, rarely returns to the mowing action range of the mowing device, and even if it returns, it is discharged Since the invasion into the cutting action range is regulated by the wind, once cut straw grass or waste straw grass is not cut twice.

In particular, the waste sward is not pinched on the tip side, unlike the sward that has a regular length in which the upper part on the tip side is clamped by the sandwiching and conveying device. For this reason, since there is no conveyance in the hanging and sandwiched state after cutting with the reaper, it is easy to drop downward after cutting, and the possibility of double cutting is very high. As described above, since it is blown off by the air discharged from the air blower (6A), like the strawberries in the state of being suspended and held by the holding and conveying device (5), the waste straws are cut twice after cutting. There is little fear.

(C) Since a lifting / conveying device that locks the straw grass blown up by the above-mentioned wind to the root side of the straw grass and guides the straw grass upward to the conveying path is provided, the straw grass is laterally guided to the conveying path reliably. be able to. And, since this lifting / conveying device is locked to the root side portion of the strawberries in a state of being blown up by the discharge air, the conveying path length of the lifting / conveying device can be set short, and the lifting / conveying device can be made compact. Can be configured.

[Advantages of the Invention] From the action (a), since it is a wind-powered selection device, it does not damage the strawberries, and the emitted wind can be evenly acted on, so there is less unselected residue of the strawweeds. .

From the action (b), by setting the time when the discharge air is applied at the time of cutting by the mowing device, there is a fear that the capacity of the mowing device may be increased in order to cope with a temporary increase in cutting load due to double cutting. In addition, the degree of entanglement between strawberries due to the return to the cutting area is reduced.

By the action (c), the strawberries can be laid down sideways and reliably guided to the transportation path, so that the workability can be improved and the lifting transportation device can be made compact, so that the manufacturing cost can be reduced. .
