A container 19 for receiving the crop falling from the end of the sorting transfer device 11 is placed in the crop input section T, a dump mechanism 21 for placing the container 19, and a container supply device for newly supplying an empty container. 23, and a transfer roller 25 disposed near the container housing 13.
[0015]
The roller 25 is disposed between the crop input section T and the container housing 13 as shown in FIG. 3 showing a sectional view taken along the line AA in FIG. The work of pulling out from the input section T and transferring it to the container storage table 13 is facilitated. Further, a sensor for detecting the operation of pulling out the container 19 from the crop input section T is provided, and a transfer control section for controlling the operation of the sorting transfer device 11 so as to be stopped by the signal is provided.
[0016]
The container accommodating pedestal 13 is arranged on the side of the control seat 5 along the longitudinal direction of the airframe, and sequentially feeds the container 19 received at the entrance from the crop input section T to an end portion on the front end side of the airframe. It is constituted by a carrier device including a belt conveyor, a chain drive roller and the like. A guide 13a for guiding the container 19 from the crop input section T through the entrance of the container storage table 13 to the terminal end is provided on the outer periphery of the container storage table 13.
[0017]
As shown in the plan view of the sensor arrangement of the container pedestal 13 in the container pedestal 13, the crops are collected at a predetermined position at the entrance of the container pedestal 13, that is, at the position of the outer end of the container pedestal 13. An entrance sensor 26 for detecting that the container 19 has been received from the loading section T and an end sensor 27 for detecting the arrival of the container at the front end side of the container housing 13 are provided. Each sensor can reliably detect the presence of the container 19 by arranging the sensor at a height such that the contact interferes with the bottom surface of the container. For example, the carrier device of the container housing 13 sends the container 19 in the direction of the terminal in a range up to the position adjacent to the container 19 in accordance with the signal of the entrance sensor 26 within a range until the signal of the terminal sensor 27 is received.

The vegetable harvester provided with the harvest storage device having the above-described configuration harvests vegetables such as carrots from the field by the harvesting device 9 in synchronization with the traveling of the airframe, and the harvested product that has undergone processing such as foliage removal is collected by the harvesting device 9. The remaining leaves are removed by the lower remaining leaf processing device 15 and are spread on the sorting transfer device 11 via the relay conveyor 17. The harvested product is dropped and thrown into the container 19 by being visually sorted by the operator of the work seat 18 while being transported to the harvested product input portion T at the end.
[0020]
The container 19 of the crop input section T receives the input of the crop from the sorting transfer device 11 to the container 19 while the input drop is kept small by the dump mechanism 21, and is held at the lowest position when the container is full. When the worker of the work seat 18 pulls out the container 19 from the crop input part T in the direction of the container storage 13, the container 19 is sent to the container storage 13 via the transfer roller 25.
[0021]
At this time, the sorting transfer device 11 stops the transfer operation by the transfer control unit according to the sensor signal for detecting the container discharge of the crop input unit T, and the container supply device 23 sends the empty container to the harvest input unit T during that time. In addition to the supply, the container 19 is received on the container housing 13 by detecting the container 19 received from the crop input section T and performing a feeding operation of the carrier device of the container housing 13 at a predetermined pitch.
[0022]
Therefore, when the worker pulls out the container 19 from the crop input section T, the operation of the worker does not cause the dropping of the crop from the sorting / transferring device 11 and the replacement of the container 19 and the container receiving table. Since the sorting and storing are performed on the container 13, the load of handling the container is reduced, and the sorting operation by the operator can be immediately restarted. Therefore, the sorting accuracy of the crop can be improved without lowering the vegetable harvesting efficiency. Can be planned.
[0023]
Next, another configuration example of the container storage table of the harvest storage device will be described.

The driven portion 14b occupies a range b adjacent to the sending portion 14a and extending to the terminal end on the front end side of the fuselage. When the container 19 is sent out from the sending portion 14a, the driven portion 14b is pushed by the sent container and the container 1 is moved on the free roller. Extruded the distance of the individual.
[0025]
Further, as shown in a plan view of a vegetable harvester provided with a container storage table (third example) according to another example of FIG. 7, a carrier device is provided by a belt conveyor over the entire length of the container storage table 16. The length of the container housing 16 is a dimension (N × L + α) obtained by adding a margin length α to an integral multiple N of the feed length L of the container, and the end sensor 27 is arranged at that position. The allowance length α is set to a size that allows the worker to pass through. The clearance with the extra length α makes it easy for the worker to enter and exit the work seat 18, and can secure the clearance by movement even when heavy containers full of harvest are closely aligned. As a result, individual containers can be easily handled.
[0026]
Next, a harvest container according to another configuration example will be described. FIG. 8 shows a plan view of a vegetable harvester provided with a harvested product storage device according to another configuration example (part 1).

In addition, the operation of the carrier device of the container housing 13 is controlled so as to perform a one-pitch feeding operation based on the detection signal of the entrance sensor 26, and the empty container 19 is harvested by detecting the discharge of the container 19 from the harvest input portion T. By controlling the operation of the container supply device 23 so as to supply it to the material input section T, the entire crop storage device is systematized, so that the burden on the operator can be reduced.
[0028]
FIG. 9 is a plan view of a vegetable harvester provided with a harvest container according to another configuration example (No. 2). In FIG. 9, the container storage table 41 of the harvest storage apparatus is constituted by a driven mechanism including free rollers extending over its entire length. In this container storage table 41, the walking worker W at the rear of the fuselage traverses the container from the crop input section T to the container storage table 41 via the roller 25, and subsequently, moves the container at the entrance of the container storage table 41. By pushing the container 19 forward, the containers can be sequentially transferred and stored at the terminal end of the container storage table 41.
[0029]
In this case, if necessary, a one-way feed mechanism is configured in the carrier device of the container housing table 41. For example, as shown in the sectional view of the configuration of the roller shaft having the ratchet mechanism in FIG. 10, at least a part of the roller shaft 43 of the carrier device of the container housing 41 is allowed to feed in the terminal direction of the container housing 41. Then, a ratchet mechanism 45 that inhibits reverse rotation is configured. With this one-way feed mechanism, it is possible to prevent the container from returning when the body is vibrated or the like.
