A variety of structures are used for the above-mentioned high-performance work vehicle. FIG. 1 shows a generally used high-performance work vehicle for agriculture.

As shown in FIG. 1, a conventional agricultural high-performance work vehicle includes a main body 10, an endless track 20 provided at left and right sides of the main body 10, and vertical beams A telescopic boom 50 connected to an end of the vertical beam 30 to extend and retract and a vertical boom 50 connected to the telescopic boom 50 by connecting the vertical beam 30 and the telescopic boom 50, And a boarding unit 60 provided at an end of the telescopic boom 50 for performing an operation by an operator.

The main body 10 is provided with a frame for supporting a driving engine, a power transmission device (not shown), etc., and a cover 16 is provided outside the main body 10.

The engine, the power transmission device, and the like for driving the high-altitude work vehicle are generally well-known technologies, and a detailed description thereof will be omitted.

The endless track 20 includes a plurality of transverse frames 12 connected to the main body 10, a vertical frame 11 provided at each end of the transverse frame 12, And comprises a plurality of wheels (21).

In the elevated work vehicle of the above-described structure, the infinite track 20 can easily travel on a curved road surface or a slope road which is difficult to travel with the tire of a general vehicle.

A vertical beam 30 is provided on one side of the main body 10 and the vertical beam 30 supports a telescopic boom 50 and a boarding part 60 provided at an end of the boom 50.

The vertical beam 30 is biased toward the opposite direction of the boarding part 60 in order to balance the center of gravity when the operator boarding the boarding part 60.

The vertical boom 30 is provided at its end with a telescopic boom 50 which is rotatable at a predetermined angle and is adapted to be stretchable and contractible.

The telescopic boom (50) and the vertical beam (30) are connected to each other by an elevating cylinder (40).

With the above-described structure, when the lifting cylinder 40 is operated, the telescopic boom 50 can be lifted to a higher position, and then the telescopic boom 50 is stretched to further enlarge the working radius.

At the end of the telescopic boom (50), there is provided a boarding section (60) for an operator to carry on necessary work.

A stacking box support plate 64 for placing a stacking box 65 for storing harvested fruit is provided at an upper portion of a second vertical support 63 provided at an end of the telescopic boom 50.

With the above-described structure, the operator can harvest the fruit in the state of being boarded on the boarding section 60 and store it in the loading box 65. [

However, there is a problem that it is very difficult to harvest the fruit and load the stacking box 65 on the ground after filling the stacking box 65 with the above-mentioned conventional high-performance work car.

That is, in the conventional high-lift work vehicle, the stacking box support plate 64 supporting the stacking box 65 is fixed to the upper portion of the second vertical support 63. This is for the operator to easily put the fruit into the loading box 65 after harvesting the fruit.

If the height of the loading box supporting plate 64 is lowered, the worker loads the fruit by tilting the upper body after harvesting the fruit, thereby increasing the risk of safety accidents at the high position.

For this reason, the loading box support plate 64 is disposed close to the upper portion of the second vertical support 63, that is, the handle portion 66 of the boarding portion 6.

Therefore, since the support plate 64 itself is fixed at a high position, it is not easy to load the fruit into the loading box 65 and unload it onto the ground.

1, since the elevating cylinder 40 is positioned between the telescopic boom 50 and the vertical beam 30, the structure of the elevator cylinder 40 can be completely restored to the ground It can not be seated.

In other words, since the conventional high-performance work vehicle has to maintain a certain distance from the ground even if the boarding section 60 is lowered to the maximum extent, it becomes difficult to unload the loading box 65 filled with fruits with the ground.

In addition, in order to prevent a fruit damage due to an impact upon the loading of fruits and prevent a safety accident of an operator working at a high position, the conventional high work work car has a structure in which the loading box 65 is attached to the second vertical support 63 Respectively.

Thus, even if the boarding portion 60 is brought close to the ground as much as possible, the loading box 65 filled with fruits is positioned at a considerably high position on the ground, and the loading box 65 filled with fruits is unloaded to the ground .

In addition, according to the conventional high-performance work car, when the fruit is filled in the loading box 65, it is necessary to lower the fruit to the ground and then move to another place to harvest the fruit. There is an inconvenience to collect it again.

Accordingly, there is a problem that labor is required and work time is increased due to fruit harvest.

In addition, the conventional high-performance work car has a structure in which the grip portion can not be rotated in the forward and backward directions, and there is a problem that the worker is restricted in the working radius when the fruit is harvested.

On the other hand, Patent Document 1 described below discloses a high-performance work vehicle in which a high-performance work vehicle is equipped with a sensor for detecting position and height, so that a safe work can be performed. Patent Document 2 discloses a work vehicle in which a hydraulic cylinder is installed at each of four corners of a main board Patent Document 3 discloses a high-altitude work vehicle for agricultural use capable of adjusting a tilt in the left-right direction, and Patent Document 4 discloses a high-work work vehicle in which a main workbench can be stably fixed, Smooth operation and easy maintenance of a working car and an auxiliary working car.

By means of the above-mentioned side loading part 70, a large number of loading boxes 65 filled with fruits can be loaded and transported to a necessary place.

As a result, the fruit harvesting operation and the picking box 65 can be simultaneously performed, thereby reducing the labor force and greatly shortening the working time for fruit harvesting.

6, a pivoting member 69 (see FIG. 6) that rotates at a predetermined angle in the first vertical support table 62 is provided at the lower portions of both sides of the handle 66 provided at the upper portion of the boarding portion 60, .

The tiltable member 69 is formed with an arc-shaped slot 69-1, so that the grip portion 66 can be rotated at a predetermined angle toward the front and rear.

Accordingly, the work range of the operator can be expanded according to the conditions at the work site.

In the conventional high-performance work car, the grip portion 66 is fixed and the work radius of the worker is limited.

However, according to the present invention, the knob portion 66 can be freely rotated, thereby improving the convenience of the operation.

The following is an example of harvesting fruit, and explains the effect of the car on the workshop.

The empty stacking box 65 is first placed on the lifting frame 81 with the lifting and lowering unit 80 being lowered and then the lifting and loading unit 80 is lifted up to the end along the slot 82.

The lifting and loading unit 80 can be stably supported on the second vertical support 63 by pushing the lifting and lowering unit 80 to the side so that the fixing member 84 is caught in the retaining groove 83 of the slot 82 .

Then, in a state where the worker is aboard the boarding section 60, the high-performance work car is driven to a required place, and the elevating cylinder 40 and the telescopic boom 50 are operated to reach a desired position.

At this time, since the lifting and loading unit 80 is maximally lifted, the fruit harvested by the operator can be easily contained in the loading box 65, and the upper body is not required to be excessively forced, thereby preventing the risk of a safety accident.

In addition, since the loading box 65 for storing fruits is adjacent to the operator, it is possible to prevent the fruit from being damaged due to impact at the time of loading the fruit.

When the load box 65 is filled with fruit, the elevating cylinder 40 and the telescopic boom 5 are manipulated to bring the elevating cylinder 80 as close as possible to the ground, and then the elevating and lowering loading unit 80 is lowered.

4, when the lifting frame 81 is slightly lifted up and the fixing member 84 is released from the engaging groove 83, the lifting and lowering loading unit 80 is easily lowered downward by its own weight .

As a result, the loading box 65 filled with fruits is positioned very close to the ground, so that the operator on the ground can easily unload the loading box 65.

1) is fixed to the upper portion of the second vertical support 63 so that even if the boarding portion 60 is lowered as much as possible, the stacking box 64 (see FIG. 1) 65 are located at a fairly high position on the ground.

Accordingly, there is a problem in that it is not easy to unload the loading box 65 at a high position on the ground in a state where the fruit is fully loaded.

The reason for placing the stacking box support plate 64 on the upper portion of the second vertical support 63 in the conventional high work truck is to easily put the fruit into the stacking box 65 after harvesting the fruit. If the stacking box support plate 64 is positioned below the second vertical support 63, the operator has to wrap the upper body to contain the fruit, which increases the risk of safety accidents during the work.

1, the elevating cylinder 40 is located between the telescopic boom 50 and the vertical beam 30 in the conventional elevating work vehicle.

Accordingly, even if the lifting cylinder 40 is shrunk as much as possible, it is difficult to unload the loading box 65 filled with fruits because the loading unit 60 is located at a certain height position on the ground.

However, according to the present invention, when the fruit is harvested, the lifting and loading unit (80) is raised as much as possible to be positioned adjacent to the operator, and after the fruit is harvested, the loading box (65) , The work efficiency can be greatly reduced while the labor force is reduced.

In addition, there is an inconvenience in that the stacking box 65 must be collected again after lowering the stacking box 65 filled with fruits.

However, according to the present invention, as shown in FIG. 2, since the loading box 65 filled with fruits is unloaded and immediately loaded on the side loading part 70, it can be moved to a necessary place, Can be improved.

According to the present invention, as shown in Fig. 6, since the grip portion 66 provided at the upper portion of the boarding portion 6 is rotatable at a predetermined angle, it is possible to increase the working radius of the operator have.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
