Description

[Detailed Description of the Invention] [Industrial field of application] The present invention locks the straw-plant side of the straw grass that is hung and supported after cutting, feeds it sideways, and swings up the plant-side portion to select it. To a strawberries harvester provided with a stock-source locking and conveying device for bringing the stock-source-side portion into the working area of the selecting device for adding the stock.

[Conventional technology]

In this kind of strawberry harvester, conventionally, the stock-source locking and conveying device is constructed by, for example, the one proposed in FIGS. 2 and 3 of Japanese Patent Application No. 63-196612 (JP-A-2-46209). As described above, the transport belt with protrusions is simply provided.

[Problems to be solved by the device]

When the root side of the suspended straw weed is picked up and brought into the working area of the equipment by this stock-source locking transfer device, the short scraps and weeds that are dragged and caught by the stock-source part of the transfer straw May be caught by a frame or the like supporting the lateral outer end of the reaper and fall off, and stay there. Therefore, if the collected waste straws form lumps, it will hinder the transportation of the next stocker side part, and bring the stocker side part into the working area of the selecting device. Was sometimes not smooth.

An object of the present invention is to provide a mechanism which can prevent accumulation due to the accumulation of dust and straw by adding a mechanism near the end of conveyance.

[Means for Solving the Problems]

A characteristic configuration according to the present invention is that a drive rotating body that projects downward from a conveying surface of the stock-source locking transfer device is provided near the end position of the stock-source locking transfer device. Is as follows.

[Action]

In other words, the drive rotating body forcibly guides rotation of the scraps collected at the end position of the stock-source locking and conveying device, bounces them out to the lateral outside of the range where the stock-source locking and conveying device exists, and discharges the scraps Move backward to eliminate the pool. In particular, since the drive rotator is provided so as to project downward from the transport surface of the stock-source locking transport device, it is difficult for the protrusions to act, and the scraps located within the height of the transport surface and the field surface. It can also be removed by directly acting on the straw.

[Effect of device]

By providing the driving rotary member near the end position of the stock-source locking and transporting device where dust and straw are likely to accumulate and by providing it so as to project below the transporting surface, it is possible to remove scraps in the locking and transporting type. It is possible to assist the fact that there is a limit to the removal of straws, and it is possible to suppress defective feeding of the waste straws to the working area of the selecting device.
