Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strawberries harvester for harvesting strawberries to be planted in a field as the machine runs. [0002] This kind of strawberry weed harvester is used to loosen strawberries in the field with a weeding device, raise them with a raising device, cut the root of the strawberries with a cutting device, and cut the cut strawberries. The stalk tip side is sent to the rear of the machine in the same direction as the raising direction of the raising device by the stalk holding device. Then, on the plant side of the sent strawberries, a sorter is operated to take out weeds and waste strawberries that are not long enough, and then bind the strawberries and place and collect them on the mounting table at the rear. It has been conventionally known (see, for example, Japanese Patent Application Laid-Open No. 61-15613). [0003] In the strawberry harvester having the above-mentioned conventional structure, the stalk tip side of the strawberry that has been mowed is selected by the stem tip holding and conveying device until it reaches the binding point in the binding device. Since the currant transport zone that constitutes the device is configured to act on the root side of the straw grass and take out the waste straw grass, the subsequent treatment is effective in the state where a large amount of waste straw grass is removed before binding. It is useful in that it can be done. However, the curling action by the sorting device is caused by the synergistic action of the backward feeding action by the stalk-nip-conveying device and the lateral feeding action by the currant-conveying belt. If there is no holding on one side of the device that produces a positive feeding action, no further curling action occurs. For this reason, in the conventional strawberry harvester, unless the operating length of the stem nipping and conveying device and the currant conveying zone is sufficiently long,
The scrap straw that is about to be scraped off by the currant action,
There is a problem that it is sent to the post-treatment process such as binding without being separated from the regular length of strawberries to be harvested. Also, with regard to waste straw that is scraped off during transportation due to the action of the currant transport zone, if it accumulates and accumulates in the front of the machine as it is, a large amount of waste straw will accumulate in the front of the machine.
When the piled-up portion is formed, there is a possibility that the action of transporting strawberries or pickling in the sorting device or the action of traveling forward of the machine body may be adversely affected. An object of the present invention is to reduce the size of a sorting device that sorts waste straw grass in cooperation with a stalk-tip sandwiching and conveying device that sandwiches and conveys the strawberries transferred from the inducing device, and improves the pickling performance. An object of the present invention is to provide a strawberry weed harvester that avoids the adverse effects of retention and accumulation of trash weeds after currant selection. Means for Solving the Problems The technical means of the present invention taken to achieve the above object are a weeding device for weeding strawberries in the field as the machine progresses, and a weeding device. The raising device that raises the strawberries while introducing them, the cutting device that cuts the root of the strawberries in the raised field, and the stalk tip side of the strawberries that are to be clipped are placed on the upper side at the back of the sorting device. And a sorting device for picking out waste straw grass while locking and transporting the stem tip holding and conveying device for sending to the binding device and the root side of the strawberries being sent by the stem tip forcing and conveying device toward the outside of the machine. A strawberry harvester equipped with, the sorting device, so that the direction of transport of the strawberry plant origin by this sorting device and the direction of transport on the side of the strawberry stalk tip by the stalk-tipped transporting device are directed in a direction that intersects. In addition to arranging, the above-mentioned sorting device A currant conveyor belt with a locking claw that locks and conveys the strawberry plant base side that is arranged, and rotates around the vertical axis at the end of the currant conveyor belt to clamp and convey waste straw grass and discharge it a fixed length up and down A pair of rollers provided with a height, a position for the currant conveying belt and a lower position of the roller, and a conveying belt for releasing the strawberry straw with a locking claw provided to convey and discharge the hay straw from the space below the roller. It is configured by a combination of. The action by taking the above technical means is as follows. a. Since the conveying direction of the strawberry plant origin by the sorting device is set in the direction that intersects with the conveying direction of the stalk tip side of the stalk sandwiching and conveying device, the strawberry plant origin in the middle of being conveyed by the cooperation of both devices. It gives a curling action to the side and can positively remove the waste straw grass. b. Then, the sorting device, a currant conveying band with a locking claw that locks and transports a plurality of strawberries at the top and bottom of the sorting machine,
At the end of the currant conveying band, a pair of rollers with a certain length are provided at the top and bottom that rotate around the vertical axis to pinch and convey the waste straw, and discharge it. Even if it reaches the end of the transport action range of the currant transport zone before it is separated from the regular length strawberries even after being subjected to the curling action in the transport zone, the unseparated waste straw grass is processed by the pair of rollers. It can be reliably sent out and discharged. That is, the conveying direction of the stalk-tip sandwiching / conveying device that sandwiches and conveys the stalk-tip portion of the strawberries having a regular length of a certain length or more, and the action of the sandwiching / conveying force of the pair of rollers that continuously operates on the currant conveying zone. By acting in a direction away from each other, the regular strawberries having the stem tip side clamped, the stem tip is clamped by the stem tip clamping and conveying device in the direction away from the pair of rollers, and The separated waste straws are respectively sandwiched and conveyed by the pair of rollers in the direction away from the stem tip sandwiching / conveying device, whereby the unseparated waste straws are reliably separated from the regular strawberries and discharged. In other words, even if the waste straw grass reaches the end of the conveying action range of the currant conveying zone and the conveying action of the currant conveying zone disappears, the conveying force of the stem nipping conveying device and the conveying force of the pair of rollers are separated from each other. It acts and subsequently conveys the unseparated waste straw grass to separate it. Further, the nipping and conveying by this roller is not one in which the conveying length is fixed like the locking conveying by the currant conveying band, and the conveying action can be continuously given without any limitation. Even if the length of the currant conveying band is configured to be the minimum necessary length in cooperation with the cooperation with the conveying device, it is possible to achieve an intended feeding function corresponding to long waste straw. . c. Further, since a pair of rollers are provided at the end of the currant conveying band with locking claws which are vertically arranged with a certain length and are arranged vertically, there is little catching leakage of dust and straw, and the existence of the rollers. As a result, it is possible to avoid the accumulation / accumulation due to the stagnation of waste straw grass at the transporting end portion of the sorting device, and it becomes possible to perform the sorting in the sorting device even better. A conveyor belt for discharging waste straw provided at the end of the transport immediately below the roller sends the hanging waste straw toward the lower side of the transport of the roller to further improve the catching of the waste straw by the roller. Tickling brings improved sorting performance. d. Since the conveyor belt for discharging waste straw and grass is provided at the position below the currant transport belt and rollers, the waste straw that is immediately sorted by the currant transport belt and falls downward, stays at the position below the currant transport belt and near the rollers. Accumulation can be avoided by the delivery action of the lower lint-raising conveyor belt. Therefore, problems such as a decline in the curling performance or a hindrance to the forward movement of the aircraft may be obstructed due to the fact that a large amount of waste straw is accumulated and accumulated below the sorting device, which obstructs the feeding of the root portion of the strawberries by the currant transport zone. Be avoided. As described above, the conveying force of the stalk nipping / conveying device can be utilized to combine the currant conveying band with the locking claw, the pair of rollers and the conveying band for discharging the waste strawberry. As a result, it is possible to discharge sufficiently long waste straw grass without being restricted by the transport length of the currant transport zone. Therefore, it is possible to configure a sorting device having a desired feeding function that is suitable for a long waste of straw and grass with a small one having a short transport length of the currant transport belt. The currants are sorted by the currant transfer zone, and the falling litter can be discharged smoothly, and the litter is accumulated and accumulated under the sorting device, which lowers the ticking performance and hinders the forward movement of the aircraft. It can be avoided. According to the present invention, it is possible to realize a high performance and highly accurate cursive sorting device.
