Abstract

PURPOSE:To enable to perform loading, unloading, transportation and discharge easily at a high place, by a method wherein a loading platform is provided on the top of a propeller body through a pair of stays which are crossing each other and the loading platform is made ascendable, descendable and undulatable arbitrarily by a piston. CONSTITUTION:When a piston rod 12 is extended by driving a piston P, stays 2, 3 supporting both a right and left sides of a loading platform 1 are stood up while they are slided along rails 7, 10 respectively and the loading platform 1 is ascended by keeping a horizontal position as it is, in a dump and lift car collecting the fruit to a predetermined place by picking the fruit from a high branch. Feet, therefore, of a worker on a loading platform 1 are stabilized and a fruit on a high branch can be housed on the loading platform by picking the fruit freely according to its height. On the one hand, when a propeller body A is moved to a friut collecting site and a piston rod 12 is extended by removing a cover piece 11 fixed to the top of the front end of the rail 10, a roller 9 of the lower edge of the stay 3 is separated from the rail 10 and the upper edge of the stay 2 is ascended by making a support shaft 5 into a fulcrum while the upper edge of the stay 2 is being slided along the rail 7. The fruit, therefore, on the loading platform 1 is discharged by opening an opening and closing lid 13.

Description

DETAILED DESCRIPTION OF THE INVENTION It is extremely labor-intensive to collect fruits from high branches of fruit trees such as oranges and apples, or to gather the collected fruits in a certain place.

An object of the present invention is to perform the above-mentioned work with light labor using a propulsion body having a loading platform.

To explain the embodiment shown in the drawings, A is a propulsion vehicle on which a loading platform 1 is mounted, E is an engine, and B is an endless track belt driven by the engine E.

2.3 is a support leg whose intersecting middle parts are pivoted 4 and whose upper ends support both left and right sides of the loading platform 1, and the lower end of one of the support legs 2 is pivoted to the rear of the propulsion body A with a support shaft 5. Its upper end is slidably engaged by rollers 6 with a U-shaped rail 7 attached to the front back surface of the loading platform 1 and opening the inside. The upper end of the other supporting leg 3 is pivoted to the rear of the loading platform l by a supporting shaft 8, and its lower end is slidably engaged with a U-shaped rail lO mounted on the propulsion body A and opening the inside by means of rollers 9. do.

Reference numeral 11 denotes a removable covering piece with a cutout m formed on the upper surface of the front end of the U-shaped rail 1o that is open on the inside.As shown in FIG. It may be detachable with a locking screw, or the fifth
As shown in the figure, it may be inserted into and removed from guide grooves formed before and after the notch m on the upper surface of the front end of the rail 10.

One of the supporting legs 2, whose lower end is pivoted to the propulsion body A by a support shaft 5, is connected to the body A through an extendable piston rod 12 of a hydraulic pump P.

In the present invention, when collecting fruits from high branches,
When the piston P is driven to extend the piston rod 12, as shown in FIG. 1, the supporting legs 2.
3 stands up while sliding along each rail 7, 1O, and the loading platform 1 rises while maintaining a horizontal position. Therefore, the operator on the platform 1 has stable footing and can freely pick fruits from high branches according to their height and store them on the platform 1.

Next, when the piston rod 12 is retracted, the supporting legs 2.3 are laid down and the loading platform 1 is lowered while maintaining its horizontal position.

Therefore, when the propulsion body A is moved to the harvesting place, the covering piece 11 attached to the notch m formed on the upper surface of the front end of the rail 10 is removed, and the piston rod 12 is extended, the lower end of the supporting leg 3 is The rollers 9 are separated from the rails 10 through the notches m, and the upper ends of the supporting legs 2 that support both left and right sides of the loading platform 1 slide along the rails 7 and rise about the supporting shafts 5, and the fruits on the loading platform 1 are The cargo is discharged by opening the opening/closing lid 13 provided at the rear of the cargo platform.

Further, when the piston rod 12 is retracted, the supporting leg 2 is laid down and the loading platform 1 is returned to its old position.

In short, according to the present invention, when the covering piece 11 is attached to the notch m formed on the front end upper surface of the U-shaped rail 10 that opens the inside and is attached to the one-man propulsion body A, the loading platform 1
When the supporting legs 2 supporting both left and right sides of the container are erected using the supporting shaft 5 as a fulcrum, the loading platform 1 rises while maintaining a horizontal position, and becomes a lift for collecting fruit.Also, when the covering piece 11 is removed from the notch m, the loading platform 1 When the supporting legs 2 that support both the left and right sides of the truck are erected around the supporting shaft 5, the lower end of the other supporting leg 3 will be separated from the rail 10, and the loading platform 1 will be tilted low at the rear, allowing the load such as fruit on the loading platform to be lifted. By simply attaching and detaching the covering piece 11 from the rail 10, the fruit can be picked up and collected with light labor.

It goes without saying that the present invention can be used not only for collecting and collecting fruits, but also for transporting cut hay to and from the second floor of a warehouse, or for discharging it from a loading platform onto the ground.
