参照）。2. Description of the Related Art As a root vegetable loading device, one installed on a self-propelled harvester is known. The self-propelled harvester scoops up root vegetables such as onions in the field with a scooping device installed on the front side of the automatic traveling device, and it is installed on the rear side of the traveling device through the forage cutting device. It is carried by a carrying conveyor of a loading device and dropped in a container (see Japanese Utility Model Publication No. 62-28819).

類が、コンテナーの壁面に衝接したり、互いに強く衝突
し合ったりして損傷し、商品価値を低下させてしまう。In this type of transfer conveyor, the height of the end portion on the sending side is constant. Therefore, the free fall distance of the root vegetables that are delivered and dropped from the delivery end to the container becomes shorter as the storage amount increases, but becomes longer as the initial storage amount is small. Therefore, free-falling root vegetables are damaged by colliding against the wall surface of the container or colliding strongly with each other, thereby reducing the commercial value.

穫機を開示している。In order to avoid such damage, Japanese Utility Model Publication No. 2-24413 discloses that a container mounted on a lift is supported so as to be rotatable together with the lift, and the container is provided near an end on a delivery side of a conveyor. Disclosed is a harvester equipped with a root vegetable loading device that tilts and supports a container according to the amount of root vegetables to be stored.

がある。However, the structure of the root vegetable loading device is complicated by the method of supporting the container in an inclined manner. In addition, containers (usually a maximum capacity of 1
Since the center of gravity of the self-propelled harvester moves with the inclination of 500 kg), the distance between the scooping device on the front side and the field scene may fluctuate, resulting in an error in scooping the root vegetables.

ある。According to the present invention, at least the end portion on the delivery side of the conveyor for feeding and dropping root vegetables into the container can be moved up and down, and the free fall distance of the root vegetables into the container is adjusted and set to a predetermined length. In addition, the root vegetables can be prevented from being damaged by free fall, and the center of gravity of the self-propelled harvester can be maintained at the center of the traveling device.

自在に支承している。The constitution of the root vegetable loading device of the present invention is as follows. Conveyor mount movable frame a
The horizontal frame (a), the front end hanging part (b) and the rear end hanging part (c) are formed in a downward U shape, and the conveyor mounting slide frame b can be moved up and down in the front end hanging part (b). It is mounted on. The conveyor mountable movable frame a is vertically movably mounted by fitting the rear end hanging part (c) to the column part (d) erected at a required position. Between the fixed point such as the upper end of the column body (d) and the conveyor-mounting sliding frame b, the conveyor-mounting movable frame a moves up and down in conjunction with the conveyor-mounting sliding frame. The body b is a movable frame on which the conveyor is mounted.
A link mechanism (e) for vertically moving the body a by the same length is installed. The endless transfer conveyor c has a receiving side end c ′ at the lower end of the column body (d), a sending side end c ″ at the lower end of the conveyor mounting sliding frame b, and an intermediate portion. It is movably supported on the horizontal portion (a) of the conveyor mounted movable frame a.

At that time, the conveyor mounting sliding frame b is further moved up and down relative to the conveyor mounting movable frame a by the same length as the vertical movement by the link mechanism (e). Therefore, the endless transfer conveyor c can appropriately raise and lower the sending-side end c ″ while keeping the receiving-side end c ′ in the set position without changing the entire length thereof. The free fall distance of the root vegetables sent from the part c ″ to the container 13 can be appropriately maintained according to the stored amount.

と認められる。Therefore, in the self-propelled harvesting machine, even if the amount of root vegetables in the root vegetable storage container 20 is increased, the weight is evenly applied to the ground contact surface of the automatic traveling device A without being biased and the vehicle travels straight. In addition to being able to smoothly turn, the scooping device B does not lift,
It is possible to reliably pick up root vegetables without any trouble, and as described above, the loading device D can load and store root vegetables in the container 13 without damaging the root vegetables. Therefore, it is recognized as a groundbreaking harvesting machine.

の自由落下距離を調整ができる。According to the root vegetable loading apparatus of the present invention, the endless conveyer c has the receiving end c ′ held at the set position and the sending end c ″ is appropriately changed without changing the overall length. Since it can be raised and lowered, the free fall distance of the root vegetables to be delivered from the delivery end c ″ to the container 13 is
Because it can be properly maintained according to the storage amount,
It is possible to prevent damage due to free fall of the root vegetables.
Moreover, the free fall distance of the root vegetables can be adjusted by vertically moving the sending end c ″ of the endless conveyor c with a simpler structure than the conventional device.

実施できる。In addition, the self-propelled harvester equipped with the root vegetable loading device of this configuration increases in weight as the amount of the root vegetables stored in the container increases, and the center of gravity of the whole is moved to the rear of the automatic traveling device A. Even if it is attempted to move, the center of gravity of the moving base 1 can be positioned substantially at the center of the automatic traveling apparatus A by sliding the moving base 1 forward at an appropriate time. Further, the turning traveling can be performed smoothly, the scooping device B is not lifted up, and the root vegetables can be scooped without trouble.
