2. Description of the Related Art In this kind of conventional root vegetable harvesting machine, as shown in FIG.
The storage bag 8 supported by the bag support 21 from the end of the conveyor 7 at the time of collecting root vegetables only by providing
By reducing the drop of the root vegetable C into the inside, the root vegetable C is prevented from being cracked or damaged by a drop impact. That is, as shown in FIG. 8 (a), when the empty storage bag 8 is mounted on the bag support 21 and collection of root vegetables C is started, the bag receiver 22 is raised so as to be in the working posture. By raising the bottom of the storage bag 8 to a position near the conveyor 7 by swinging the container 7, the head from the conveyor 7 to the bottom of the storage bag 8 is reduced, and the root vegetables C from the conveyor 7 fall into the storage bag 8. So that they are not easily scratched.
When the collection amount of the root vegetables C in the storage bag 8 increases with the progress of the collection of the root vegetables C in the storage bag 8, the storage space for the root vegetables C in the storage bag 8 decreases or disappears. That is, when the level of the collected root vegetable group upper surface in the storage bag 8 reaches the upper limit, as shown in (b) of FIG. 8, according to the storage space remaining in the storage bag 8 and the size of the storage bag 8. By lowering the bottom of the storage bag 8 from the conveyor 7 by swinging the bag receiver 22 downward by an appropriate angle, the upper surface of the collected root vegetables in the storage bag 8 is lowered with respect to the conveyor 7, The space from which the root vegetables C enter the storage bag 8 is formed while maintaining the head from the to the top of the collected root vegetables group within a range that reduces damage to the root vegetables C due to the drop impact.

[0003]

However, according to the above-mentioned prior art, when the bottom of the storage bag is lifted by swinging the bag receiver to the operating position, the storage bag is compressed in the vertical direction. And the storage bag is wrinkled. The size and shape of the wrinkles formed in the storage bag vary, and some of the wrinkles have a size and shape that allow root vegetables falling from the conveyor to enter. Therefore, in the drop supply of root vegetables from the conveyor to the storage bag, not all of the root vegetables dropped and supplied are received by the bottom of the storage bag. In other words, there are many things caught in wrinkles.

As described above, when the bag receiver is swung downward by the upper surface of the collected root vegetables group reaching the upper limit in the state where the root vegetables caught by the wrinkles are present, the swing operation of the bag receiver downward is performed. The wrinkles are stretched and shallow due to the lowering of the bottom of the storage bag, and as a result, the root vegetables can no longer be supported by the wrinkles, and the root vegetables captured in the wrinkles fall at once, and even if the head is small, it is collected Root vegetables are subject to a large drop impact and are easily damaged.

An object of the present invention is to prevent the root vegetables from being dropped and supplied at once in a group.

[0006]

The features, functions and effects of the first aspect of the present invention are as follows.

[Features] The root vegetables pulled out from the field and conveyed via a conveyor are dropped and supplied to a storage bag supported by a bag support in an open state with the mouth facing upward, Changed to an operating position to lift and support the bottom of the storage bag suspended and supported by the bag support by an up and down swinging operation around the horizontal axis, and an open position to retract from the lower side of the storage bag and release the support. In a root vegetable harvesting machine provided with a free bag receiver, the bag support is attached to a support member such that the mouth of the storage bag moves up and down with respect to a conveyor so as to be vertically swingable. Is attached to the self-propelled body so that it can be moved up and down freely.

[Operation] Since the opening of the storage bag is moved upward by swinging the bag support upward, the bag receiver is swung upward to position the storage bag in the operating position. When the bottom of the storage bag is lifted by the bag receiver to reduce the drop from the end of the conveyor to the bottom of the storage bag, the storage bag is likely to be folded by lifting the storage bag bottom with the bag receiver. By swinging the bag support upward and moving the mouth of the storage bag upward, the storage bag is extended upward, and wrinkles that can be formed in the storage bag can be lengthened to form the storage bag. Wrinkles,
Root vegetables supplied by falling can be made shallow so that they are difficult to catch.

In accordance with an increase in the amount of collected root vegetables as the collection progresses, the bag receiver is pivoted downward while the bag support is pivoted downward to support the bottom of the storage bag. The position to be moved downward, the rise of the collected root vegetables group upper surface relative to the conveyor is regulated, and the vertical position of the collected root vegetables group upper surface relative to the conveyor can be kept constant or almost constant, so from the end of the conveyor to the collected root vegetables group upper surface. Can be maintained as small as at the start.

In addition, since the supporting member, that is, the bag supporting member can be freely moved up and down with respect to the self-propelled body, at the time of collecting root vegetables, the supporting member is positioned upward to suspend the storage bag by the bag supporting member. When the bag holder is in the open position, the storage bag can be lifted off the ground to avoid grounding of the storage bag, and damage to the storage bag caused by grounding and collection of root vegetables When the empty storage bag is attached to the bag support or the storage bag containing the root vegetables is removed from the bag support, the support member is lowered. The bag support is positioned low on the ground, making it easier to install and remove the bag support.Especially, when removing the storage bag containing root vegetables from the bag support, the bottom of the storage bag is grounded and the storage bag is Load on the ground By so as to, the ability to reduce the load applied, such as a string giving multiplying the storage bag to the bag support, it is possible to very easily carry out the removal from the bag support of the container bag, such as Himohazushi.

[Effects] As a result, according to the first aspect of the present invention, it is possible to reduce the head when the root vegetables are dropped and supplied from the end of the conveyor to the storage bag, and to suppress the wrinkles into which the dropped root vegetables enter into the storage bag. Synergistic with the fact that the root vegetables can be prevented from falling all at once, it is possible to reduce the drop impact acting on the root vegetables and reduce the damage to the root vegetables, and it is naturally necessary if the storage bag is full of root vegetables When the removal and recovery of the full storage bag from the bag support is continued, the necessary empty storage bag can be attached to the bag support with good workability.

The features, functions and effects of the second aspect of the present invention are as follows.

[Features] In the features of the first invention,
When the bag support is located at the upper end of the vertical swing range, the bag receiver is in the operating position, and when the bag support is located at the lower end of the vertical swing range, the bag receiver is in the open position. An interlocking member for interlocking the support and the bag receiver is provided.

[Operation] In collecting root vegetables with the storage bag suspended by the bag support and the bottom of the storage bag loaded on the bag receiver, as described above, the bag support is swung upward. The collection operation is started by swinging the bag receiver upward so that the bag holder is in the working posture, and the bag support and the bag holder are gradually rocked downward as the amount of collection increases. It is. That is, when the bag support is pivoted upward, the bag receiver is also pivoted upward, and when the bag support is pivoted downward, the bag receiver is also pivoted downward. .

Focusing on the above points, an interlocking member is provided to interlock and connect the bag support and the bag receiver so that the bag receiver reversibly moves upward with the upward swing of the bag support. Since it is configured to swing, when swinging the bag support and the bag receiver up and down, only one of the bag support and the bag receiver need only be swung up and down. . This means that, when the swing operation is performed by an actuator such as a hydraulic cylinder or an electric motor, only one of the actuator that operates the bag support and the actuator that operates the bag receiver is required.

[Effect] As a result, according to the second aspect of the present invention, the swing operation for the bag support and the bag receiver can be easily performed. In particular, when the operation is performed using the actuator, only one actuator is required. , Can be implemented economically.
