2. Description of the Related Art Conventionally, Japanese Patent Application No. 5-28939 and Japanese Patent Application No. 5-28939
As can be seen in Japanese Patent No. 120606, in front of a self-propelled traveling machine body, an integrally configured petal picking means and a lateral feeding device are vertically and tiltably connected, and a petal housing frame is provided behind the traveling machine body. Conveying conveyors arranged in series and arranged between the lateral feed device and the petal storage frame are arranged on the side of the traveling machine body, and the petals picked by the petal picking means are conveyed to the storage frame while traveling. A flower picking machine has been devised, and in order to tilt the petal picking means and the lateral feed device to the left and right, the left and right front lift arms that hydraulically move up and down forward from the traveling machine body are projected forward, and the tip of the front lift arm. One side of the lateral feed device is pivotally attached to the part so that it can be tilted left and right, and a tilting hydraulic cylinder is provided between the other side of the lateral feed device and the tip of the bracket that is erected in the middle of the front lift arm. Hydraulic cylinder And so as to laterally tilting a and transverse feeder petal picking means by condensation operation.

Further, the petal picking means is configured to be driven by a hydraulic motor shared with other hydraulic equipment.

Further, valves for controlling the hydraulic equipment are distributed and arranged in various places of the machine body.

[0005]

However, in the above-mentioned prior art, when an attempt is made to give a sufficient left-right tilting angle to the petal picking means and the lateral feeding device, the vertical stroke on the other side of the lateral feeding device becomes long, and therefore, Therefore, a long tilting hydraulic cylinder is required.

Further, since the stroke is long, there is a problem in that if the lowering operation of the petal picking means and the other side of the lateral feeding device is dependent on the gravity, it takes a long time to descend and the work efficiency is lowered.

Therefore, using a double-acting hydraulic cylinder,
If both the raising and lowering of the side portion of the transverse feed device are performed by hydraulic pressure, a long double-acting hydraulic cylinder is required, which is disadvantageous in terms of cost.

Further, since the petal picking means is driven by a hydraulic motor shared with other hydraulic equipment, when the other hydraulic equipment is operated, the rotational speed of the hydraulic motor changes.

Further, since the valves are distributed and arranged in various places of the machine body, the installation place is wide, the operation is complicated, and the maintenance is troublesome.

[0010]

Therefore, in the present invention, in front of the traveling machine body, the petal picking means and the transverse feed device which are integrally configured are connected continuously via the left and right front lift arms so as to be vertically movable and tiltable, A petal storage frame is connected to the rear of the traveling machine body, and a transport conveyor installed between the traverse device and the petal storage frame is arranged on the side of the traveling machine body, and the petals picked by the petal picking means are stored in the housing frame. In the flower picking machine configured to be transported to one side, one side part of the transverse feeding device is pivotally attached to the tip part of one front lift arm so as to be rotatable, and a left-right pivot shaft is provided in the middle part of the other front lift arm. It projects and pivotally supports a middle part of the swing arm on the same pivot shaft, connects a hydraulic cylinder for tilting to the rear end of the swing arm, and feeds the front end of the swing arm sideways. Linked to
