Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and an apparatus for controlling the posture of bulbs harvested from a field and having a stalk attached to the bulb or main root using wind power.

The stems and bulbs of rakkyo, onions, garlic, tulips, gladiolus, etc., as well as the roots of carrots)
When harvesting bulbs such as turnips, turnips, beets, etc., which have clearly separated stem and taproot parts, they can be efficiently dug up using a power digging machine, etc. The current situation is that a great deal of labor and time is required for the preparation work of removing the stems and fine roots.

In order to streamline such preparation work, the applicant has proposed, for example, an apparatus for cutting off the stem and fine roots from the bulb of rakkyo. Additionally, devices for cutting stems and fine roots from onion bulbs have long been known, but these devices cut off stems and fine roots from onion bulbs. If the bulbs are not supplied in a constant posture, the stems and leaves and fine roots cannot be removed from the bulb as desired, and controlling this posture is an issue to be solved in mechanized preparation work.

The present invention was conceived in view of the above circumstances, and involves dropping bulbs with stems and leaves harvested from a field through a wind path that blows pressured air from below upwards, and applying wind force to the falling bulbs. Posture control of bulbs that can be controlled to have a posture with the bulb part facing down and the stem and leaf part upward, and can be derived in a constant posture, and can be linked with the above-mentioned jaw adjustment value etc. to enable highly efficient and highly accurate preparation work. A method and apparatus thereof are provided.

The invention will now be described with reference to illustrated embodiments.

In the figure, reference numeral 1 denotes a conduit provided vertically in the vertical direction. A hopper 2 is integrally connected to the upper end of the conduit 1, and the lower end of the conduit 1 is divided diagonally downward into two directions. The air pipe 3 is open on one side, and the outlet pipe 4 is opened on the other side.
It becomes. A blower 5 is provided at the lower end of the blower pipe 3.
is provided in the conduit 1 to blow up pressure air from below to above, and the outlet pipe 4 is configured to blow the rakkyo A whose attitude is controlled in the conduit 1 to the outside in a constant posture. It is designed to be derived. The outlet pipe 4 may be shifted downward in relation to the blower pipe 3, as shown by imaginary lines in the drawing.

A supply conveyor 6 is provided above the hopper 2 so that the end of conveyance faces the opening position of the supply conveyor 2, and the supply conveyor 6 is used to collect the rakkyo A that has been excavated from the field and has its stems, leaves, and fine roots still attached to the bulbs. is transported and dropped into a hopper 2, where it is supplied. Further, below the outlet pipe 3, there is provided a conveyor 1 for carrying out the rakkyo discharged from the outlet pipe 3.

In the attitude control device having such a configuration, Rakkyo-A, which has stems, leaves and fine roots attached to the bulbs excavated from the field, is randomly placed on the supply conveyor 6 and transported. Drop into hopper 2 from the end. The rakkyo A falling from the hopper 2 into the conduit 1 is fed into the conduit 1 from the blower 5 through the blast pipe 3, and by the pressure air blowing upward from below, the heavy bulb part is moved downward. The stems and leaves are controlled to be in an upright position, reach the lower part of the conduit 1, and are discharged from the outlet pipe 4. Then, it is placed in a certain direction on the carry-out conveyor 7 and carried out in a predetermined direction. Although not shown, the transport end of the conveyor 1 for carrying out is connected to an automatic preparation machine that cuts the stems, leaves and fine roots from the bulbs of rakkyo, for example. .

In addition, in the above embodiment, a case was explained in which a rakkyo was used as the object to be controlled by the posture control unit, but instead of a rakkyo,
Onions, garlic, tulips, gladioli, which are harvested from the field, have stems and leaves attached to the bulb or main root, and where the stem and leaves are clearly separated from the bulb or main root.
It can also be used for bulbs such as carrots, turnips, and beets.

In addition, the posture controlled device according to the present invention can be used not only in connection with the preparation Ill for cutting the stem and leaves from the bulb, but also in a wide range of tasks, such as sorting work at the time of shipping, container and boxing work, etc. It is.

As explained above, according to the method for controlling the posture of bulbs according to the present invention, it is possible to control the posture of bulbs in a certain direction using extremely simple means, and to extract the stems, leaves, fine roots, etc. from the bulbs. In conjunction with a preparation device for cutting, it is also possible to perform operations such as bagging, boxing, and packaging at the time of shipping efficiently and accurately.

Further, the posture control device of the present invention has an extremely simple configuration, so the jaw structure cost is low, and the operation is simple and easy, and there are no parts that can cause failures, and it can exhibit stable performance.

Claims (2)

[Claims] (1) Bulbs harvested from field II where the eastern part of the stem and the bulb part of rakkyo, onion, garlic, tulip, and gladiolus are clearly separated, and the eastern part of the stem and main root part of carrot, turnip, and beet are clearly separated. Roots are allowed to fall through an air channel formed in the vertical direction, and pressurized air is sent from below this air channel to blow up and hit the falling bulbs. A method for controlling the posture of bulbs, characterized in that the bulbs are controlled in a posture with the stem part facing upward, and the bulbs are guided out from the lower part of the air path in a constant posture. (2) A conduit for dropping bulbs harvested from the field and with stems attached to the bulb or main root, and a conduit installed at the bottom of this conduit to blow pressurized air from below to upwards into the conduit. The method is characterized by comprising: a blower section; and a guide section that guides out the bulbs that fall under the control of the pressure air so that the bulb section or main root section is downward and the stem section is upward in a constant posture. A posture control device for bulbs.
