る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention is provided with a holding and conveying device for holding the stem tip side portion of cut strawberries and hanging them to convey them to the rear, and is sent by the holding and conveying device. A side-feed locking and transporting device that acts on the root side of strawberries to feed it sideways is provided, and the root-side portion of the strawberries sent by the side-feed locking and transporting device is blown up sideways to perform selection. It is a straw harvester equipped with a wind power device, and by adopting a wind power device, it does not forcibly pick up the straw grass compared to what is selected by the locking claws, so the selected wind does not damage the stem part The present invention relates to a strawberries harvester having a characteristic configuration such that it has a high selection performance because it divides into strawberries and performs a uniform selection action.

記吐出口からの放出風に作用させる構成であった。In this type of strawberry harvester, conventionally, for example, as proposed in Japanese Patent Application No. 63-175585 (Japanese Patent Laid-Open No. 2-27920), the portion of the strawberry plant on the root side suspended and supported by the holding and conveying device. Is provided with a lateral feed locking transport device for laterally locking and transporting, and the end of the lateral feed locking transport device is set in front of the discharge port of the wind power device, and the root side of the strawberries is discharged from the discharge port. It was designed to act on the air emitted by the.

なかった。However, even if such a configuration is adopted, since the transverse feed locking and transporting device locks and transports, when it reaches the vicinity of the discharge port of the wind power device, due to the effect of the emitted wind, The former part was pushed out to the discharge air action area on the contrary, and it escaped not in the lateral direction but in the front-back direction, and a sufficient selecting action was not performed.

残っている。Therefore, a fixed guide rod is provided on the side of the conveying path of the lateral feed locking and transporting device to prevent the strawberries locked by the lateral feed and locking transporting device from coming out of the locking mechanism and to guide the discharge port. It is also possible to provide a.B. If the volume of strawberries fed by the side-feed locking and conveying device becomes large, it will cause clogging, and conversely, if the guide rods are installed at intervals so as not to cause clogging, it will There is still a problem that the function is not fulfilled sufficiently, and because the strawberries are sent along this guide rod, the strawberries are damaged by the contact resistance.

果は次の通りである。According to a characteristic configuration of the present invention, a drive rotation guide body is provided on the opposite side of the transverse feed locking conveyance device across the conveyance path of the transverse feed locking conveyance device, and the lateral feed locking conveyance device and the drive rotation guide body are provided. Is configured so as to guide the stock-source side portion to the discharge wind action area of the wind power device, and the action and effect thereof are as follows.

〔作用〕[Action]

つまり、前記風力装置の吐出口近くにおいて、前記横送

元側部分を囲む状態で搬送し乍ら、前記駆動回転案内体

株元側部分を押し込むことができる。That is, in the vicinity of the outlet of the wind power device, the lateral feed locking transfer device and the drive rotation guide body convey the transfer strawberries in a state of surrounding the root side portion of the strawberries. Thus, it is possible to forcibly push the portion of the strawberry plant base side into the action area of the wind flow of the wind power device.

〔発明の効果〕〔The invention's effect〕

したがって、前記横向き係止搬送装置単独では吐出風に

た。Therefore, in the lateral locking transport device alone, the drive rotation guide body receives the stock-side portion that escapes by the discharge wind, and by forcibly pushing in with this rotary body,
The selected wind can be surely applied. Moreover, since the drive rotation guide body forcibly pushes in, it can be pushed into the discharge air action area even when the volume of the root side of the transport strawberries increases, and because it is a rotating body, it is a fixed guide. The frictional contact is less than that of the rod, and the good sorting function by the sorting wind can be effectively utilized.
