Pattern description

The object of the utility model is a discharge device, especially for box pallets.

The harvesting of fruit in large fruit orchards is a serious problem due to the accumulation of works in a short period of time. This problem is especially the transport of fruit harvested from the trees to the cold store, the place of storage. This applies especially to the transport of apples in standardized box pallets inside and outside the orchard. Pallets contribute to the efficient collection of fruit from the trees, but they require quick removal from the orchard and then unloading.

Unloading box pallets require a lot of work when unloading is manual. Industrial fruit does not require gentle treatment and unloading of box pallets can be done by pouring out. The problem is spilling fruit from box pallets, containing several hundred kilograms of fruit, to a greater height.

A device cooperating with a forklift is known in which the outer frame is rotatably arranged in the outer frame mounted on the forklift. The inner frame is equipped with forks for lifting the box pallet and a safety frame that prevents the box pallet from sliding off the forks of the inner frame. The inner frame is pivoted on a pin relative to the outer frame by a string attached on one side to the inner frame and on the other side to the forklift mast via a roller system. The device of this type is suitable for unloading wooden box pallets with a lower board on the bottom side of the legs, because in such an embodiment, the nests made by the structure of the box pallet, into which the forks of the unloading device enter, prevent the pallet from falling out of the device.

However, more and more plastic box pallets are in use that do not have slots in the leg area. There are also wooden boxes that do not have the sockets described above. In this case, when the box pallet is tilted during unloading, the box pallet may fall out of the unloading device from a great height.

The purpose of the utility model is to avoid the presented unloading difficulties, and also to increase the types of means of transport in modern orchards.

The discharging device, in particular for box-pallets according to the utility model, comprises an outer frame mounted in the usual manner on the mast of a forklift. In the outer frame there is a pivoting inner frame provided with forks for picking up the box pallet. The inner frame has a restraining frame pivotally disposed thereon and is provided with an upper stop.

Preferably, the upper limiter is a flat bar mounted on the supports.

It is also preferred that the upper stop is provided on the side walls and the rear wall of the inner frame.

The upper stop can advantageously be arranged on the side walls of the inner frame.

Also advantageously, the upper stop can be arranged on the rear wall of the inner frame.

The object of the utility model is shown in the drawing, in which Fig. 1 shows the discharge device in a side view with a stop on the side walls and a rear wall of the inner frame, Fig. 2 shows the discharge device in a side view with a stop on the side walls of the rear inner frame, Fig. 3 shows the discharge device in a side view with a stop on the rear wall of the inner frame, Fig. 1 shows prior art devices.

The unloading device 1 according to the utility model has an outer frame 2 which is mounted on a forklift. In the outer frame 2, an inner frame 4 is rotatably mounted on a pin 3. The inner frame 4 is provided with forks 5 for lifting the box pallet. On the inner frame 4, a limiting frame 6 is arranged. The limiting frame 6 is connected by means of a roller system 7 by means of an elastic cable 8 to a forklift.

The inner frame 4 is provided with an upper limiter 9 mounted on brackets 10 fastened to the inner frame 4. The upper limiter 9 is a flat bar and it can run along the side walls and the rear wall of the inner frame 4 or only along the side walls of the inner frame 4 or only along the rear wall. inner frame 4.

The operation of the discharge device 1 according to the utility model is as follows:

The fruit box pallet is lifted slightly by the forks 5 of the inner frame 4. The inner frame 4 with the box pallet is placed in the outer frame 3 in position

Claims (5)

3 PL 66 239 Υ1 horizontal. After reaching the place of emptying the box pallet with a forklift, the unloading device 1 is lifted on the mast of the forklift. This causes the limiting frame 6 to pivot against the inner frame 4. Further lifting of the device on a forklift causes the inner frame 4 to tilt relative to the outer frame 3 and consequently empty the box pallet. The upper stop 9 prevents the box pallet, especially the plastic one, but not only from falling out of the discharge device 1 during unloading. Protective Claims 1. Discharge device, in particular for box pallets, having an outer frame mounted on a forklift, in which an inner frame with forks is pivotally pivoted and provided with a limiting frame, characterized in that the inner frame (4) is provided with an upper stop (9). 2. The discharge device according to claim 1, 3. The device according to claim 1, characterized in that the upper limiter (9) is a flat bar mounted on the supports (10). 3. The discharge device according to claim 1, The device of claim 1, characterized in that the upper stop (9) is arranged on the side walls and the rear wall of the inner frame (4). 4. The discharge device according to claim 1, The device of claim 1, characterized in that the upper stop (9) is arranged on the side walls of the inner frame (4). 5. The discharge device according to claim 1 A device according to claim 1, characterized in that the upper limiter (4) is located on the rear wall of the inner frame (4).
