Description

[Detailed description of the invention] This invention relates to a trailer equipped with packets, and its purpose is to overturn the packets when loading and unloading items stored in the packets onto a transporter such as a truck. To provide a trailer whose position can be changed appropriately according to the height of a loading platform of a transport vehicle, thereby enabling stored items to be lowered and lowered without damaging them.

Conventionally, various types of trays equipped with packets of this type have been developed, but the supporting rods that support the packets are fixed to the trolley, so the position of the packets is always constant. Therefore, the position (height) at which the packet overturns does not change.

Therefore, when loading and unloading items stored in a packet onto a transport vehicle such as a truck, if the height of the loading platform of the transport vehicle is extremely low, the height between the packet and the loading platform will increase, causing the stored items to be unloaded. They are easily damaged by falling, which greatly affects shipment volume, especially in the case of potatoes.

Therefore, the present invention was constructed in order to solve the above-mentioned problems, and the support rods are pivoted to the left and right sides or the front and rear sides of the cart or the underframe that is detachably attached to the cart, so that the support rods can be freely rotated up and down. The upper end of the side wall of the packet formed in the shape of an inverted trapezoid is pivotally supported at the upper end of the support rod so that the packet can be transferred freely, and in the middle of the support rod is a support whose base end is pivoted on a cart or underframe. The rod tip of a hydraulic cylinder for raising and lowering the rod was pivoted, and the base end of a hydraulic cylinder for reversing the packet was pivoted to the cart or underframe, and the rod tip of the hydraulic cylinder was pivoted to the upper part of the side wall of the packet. The gist of this is that

To explain an embodiment of the present invention in which the packet is reversed backwards, 1 is a trolley with a traction rod 7 extending and protruding forward, and wheels 8 on both sides of the rear part that rotate freely. It can be towed by a truck or the like.

An underframe 2 is removably attached to the upper surface of the truck 1 with fasteners 9 such as bolts, nuts, or bottles, and supporting rods 3 and 3' are attached to the upper surface of the underframe 2 or the truck 1 so that they can be raised and rotated automatically. It is mounted on a shaft.

The supporting rods 3 and 3' are rod rods bent in an R-shape from the front, and the lower ends thereof are fixed to the mounting plate 1 on both left and right sides of the truck 1 or the underframe 2.
A package 1 having an inverted trapezoidal front face is pivotally attached to the upper ends of the support rods 3 and 3' by shafts 12 at the upper and rear sides of both sides.

The packet 4 is formed into an inverted trapezoid shape using a flat metal plate or a flat synthetic resin plate, and has an open top surface for loading and unloading stored items. The upper ends of the support rods 3, 3' are supported by a shaft 13, and the tip of the rod σ of a hydraulic cylinder 6 for reversing the packet is supported by a shaft 13 in the middle of the upper part of both sides.
A hydraulic cylinder 5 for raising and lowering the support rod is attached between the middle part of the support rod 3' and the rear upper surface of the truck 1 or the underframe 2.

The hydraulic cylinder 5 has its base end rotatably attached to a support frame 14 fixed to the rear upper surface of the truck 1 or the underframe 2 through a shaft 15, and the tip of the rod 5' is attached to the intermediate portion of the support rods 3, 3'. The supporting rods 3, 3' supporting the packet 4 are pivoted up and down by the protrusion and retraction movement of the rod 5' by the operation of the hydraulic cylinder 5, and accordingly, the supporting rods 3, 3' are aligned with each other. The position (height) from the ground of the shaft 12 on which the packet 4 is mounted is vertically variable.

The hydraulic cylinder 6 has its base end rotatably supported by a shaft 18 on a support frame 17 fixed to the upper surface of the cart 1 or the underframe 2, and the tip of the cylinder 6 is attached to a shaft 13 in the middle of the top on both sides of the packet 40. The packet 4 supported on the support rod 3.degree. 3' is reversed backwards about the shaft 12 by the movement of the rod .sigma. by the action of the hydraulic cylinder 6.

When loading and unloading the items stored in the packet 4 onto a transport vehicle such as a truck, the worker first operates the hydraulic cylinder 5 for raising and lowering the support rod according to the height of the transport vehicle's platform, and the packet 4 is reversed. Adjust the position [height from the ground to axis 12],
Thereafter, the hydraulic cylinder 6 for reversing the packet is operated to reverse the packet 4 backwards, and the stored items are unloaded onto the carrier.

Note that the base ends of the support rods 3 and 3' that support the packet 4, the hydraulic cylinder 5 for raising and lowering the support rod, and the hydraulic cylinder 6 for reversing the packet are not attached to the cart 1, but can be freely attached to and detached from the cart 1. By attaching it to the underframe 2 placed on the frame 2, the trolley 1 can not only be used by mounting the packet 4, but also can be used by attaching other attachments.

Furthermore, although the embodiment illustrated above is a form in which the packet 4 is reversed backwards, the present invention is not limited to reverse backwards.
It is also possible to reverse (roll over) in the left-right direction, and in this case, the lower ends of the support rods 3, 3' are pivoted to the front and rear of the truck 1 or the underframe 2 that is detachably attached to the truck 1, and This can be achieved by attaching the hydraulic cylinder 5.6 in the same manner.

As described in detail above, the present invention has a support rod rotatably attached to the left and right sides or both front and rear sides of a cart or an underframe that is detachably attached to the cart, and an inverted trapezoid shape is attached to the upper end of the support rod. The upper part of the side wall of the formed packet is pivoted to allow the packet to be transferred freely, and the rod tip of a hydraulic cylinder for raising and lowering the support rod, whose base end is pivoted on a truck or underframe, is installed in the middle of the support rod. Furthermore, the base end of a hydraulic cylinder for reversing the packet is pivotally attached to the cart or underframe, and the rod tip of the hydraulic cylinder is pivotally attached to the upper side wall of the packet, so that the pivot position for the reverse movement of the packet is fixed. This can be done by changing the vertical direction.

That is, by operating the hydraulic cylinder for raising the bearing rod that supports the packet, the height of the supporting rod that supports the packet can be adjusted in height, and then the hydraulic cylinder for reversing the packet is activated. When activated, the packets can be reversed and the stored items can be dropped onto and unloaded onto a truck or other transport vehicle.

Therefore, if the height of the loading platform differs depending on the type of transport vehicle, the support rod can be moved up and down according to the height of the loading platform, and the position where the packet is reversed can be adjusted to the optimal position. It is very useful because it does not cause the sun to shine even if the object falls, and it is effective when the stored object is potatoes or the like.

In addition, the support rod and hydraulic cylinder that supported the packet are not attached directly to the trolley, but are attached to an underframe that is detachably attached to the trolley, allowing other attachments to be attached without using the trailer as a dedicated vehicle for packets. In particular, it can be used for a wide range of tasks.
