Description

[Detailed description of the invention] This invention relates to a potato harvester equipped with a bag device for temporarily storing potato potatoes.

The potato harvester temporarily stores the harvested potatoes on the harvester, but in conventional containers such as dump-type mini containers and unloader-type tanks, there is a drop from the conveyor discharge end of the harvester to the bottom of the container. Because the amount is too large, the potatoes are not only damaged during storage, but also damaged due to collisions and rolling of the potatoes when they are discharged.

Moreover, it is heavy and bulky, making it difficult to handle the container, and there are disadvantages in use, such as overloading when working.

The purpose of this invention is to provide a potato harvester equipped with a bag device that causes less damage to potatoes during storage and discharge, and requires little effort in handling. , a mast is rotatably attached to the base of the harvester, an arm is attached to the mast so that it can tilt up and down,
A bag is hung from the end of the arm, and the bottom of the bag can be opened and closed.

The device of this invention will be explained based on the embodiment shown in the drawings.

As shown in FIG. 1, a mast 4 is rotatably erected on a platform 1 of a potato harvester towed by a tractor, and an arm 5 is pivoted to the mast 4 so as to be tiltable up and down.

A hydraulic cylinder 7 is disposed between the mast 4 and the arm 5, and the arm 5 is tilted by hydraulic pressure.

A hook 8 is attached to the tip of the arm 5, and a hanging ring 9 is hung on the hook 8.

A bag 6 made of a flexible material such as cloth is placed on the harvester in a frame 21 fixed to the platform 1 below the discharge end of the conveyor 3.

As shown in FIG. 2, a cap 11 is attached to the upper peripheral edge of the bag 6 to maintain the opening shape.

Each of the plurality of ropes 10 whose lower ends are fixed at equal intervals to the lower peripheral edge of the bag 6 passes through rings 13 which are also fixed at equal intervals to the base 11, and whose upper ends are fixed to the hanging ring 9.

As shown in FIG. 3, the bottom surface of the bag 6 is formed of several opening/closing pieces 14 that overlap in the center with adjacent parts.

An opening/closing metal fitting 15 is fixed to one of the opening/closing pieces 14, and a hole 17 into which the metal fitting 15 fits is bored in the other opening/closing piece 14.

It is desirable that the hole 17 be reinforced with a rim.

As shown in FIG. 4, two hooks 16 are pinned to the cylindrical body 23 of the opening/closing fitting 15 so as to be movable from side to side.

When the pin 19 is inserted into the stopper hole 18, the hook 16 is fixed in the protruding position.

In this case, the opening/closing piece 14 cannot be separated from the cylindrical body 23, so that the bottom of the bag 6 remains closed.

On the other hand, when the pin 19 is removed from the hole 18, the hook 16 rotates inward and is retracted, and the opening/closing piece 14 can be detached from the cylindrical body 23.

That is, the bottom of the bag 6 can be opened.

A string 20 for a pulling operation is attached to the pin 19.

Although the bag in the embodiment has a circular cross section, it goes without saying that bags with a square cross section can also be used.

Further, although the opening/closing fitting of the bag according to the embodiment opens and closes the bottom surface by inserting and removing the hook, other types of fittings may be used, such as a type in which the opening/closing piece is directly fastened with a pin that can be inserted or removed.

Although not shown, the hydraulic system that rotates the mass 1-4 and the hydraulic cylinder 7 that tilts the arm 5 up and down are operated by a hydraulic outlet of the tractor or a hydraulic pump built into the harvester.

Next, the stuffing and discharging of potato strips using the device of this invention will be explained.

To put food into bag 6, first insert the mouthpiece 1 of bag 6.
1 is locked to the frame 21, and the arm 5 is raised to raise the bottom surface.

As a result, the drop between the conveyor 3 and the bottom of the bag 6 becomes small, and even if the potatoes fall from the conveyor 3 into the bag 6, little damage will occur.

As the bag 6 is filled with potatoes, the arm 5 is lowered little by little, and the potatoes are loaded from the conveyor 3 into the bag 6 while maintaining a slight drop.

When bag 6 is full of potatoes, as shown in Figure 6,
The bottom of the bag 6 rests on the pedestal 22.

In this state, the loading of the potatoes is stopped and they are transferred to another large transport vehicle such as a dump truck.

For this purpose, the arm 5 and the mast 4 are operated to shift the bag 6 to the side of the conveyor 3 and place it on the platform of a dump truck or the like.

When the string 20 is pulled on the loading platform, the pin 19 comes out of the hole 18 of the cylindrical body 23, the hook 16 is retracted, and the opening/closing piece 14 comes off from the cylindrical body 23 due to the weight of the potato, and the bottom of the bag 6 opens.

In this way, the potatoes are transferred to the loading platform, but in this case as well, there is no drop, so there is little chance of damage to the potatoes.

When transporting (I put it in a bag), remove the rope 10 from the hanging ring 8 and hang a new bag from the hanging ring 8.

As mentioned above, the device of this invention temporarily stores potatoes (potato tubers) in a bag made of flexible material with a constant small drop, and allows the packed potatoes to be quietly and without much effort. Since it can be transferred to the bed of another transport vehicle and emptied, damage to the material is significantly reduced and labor requirements are significantly reduced compared to conventional devices.
