Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onion rooting machine for removing onion roots.

[0002]

2. Description of the Related Art Harvested onions need to be cut off at the time of shipment after being dried for a predetermined period. At the time of shipping the onions, it is necessary to root a large amount of the onions within a short period of time. When the rooting work is performed, the rooting work is performed continuously for a considerable period of one day.

Conventionally, when rooting an onion, the root was manually cut off with scissors.

By the way, the roots of dried onions are hardened by drying and extend in irregular directions. Therefore, if you cut the onion root with scissors,
It is necessary to put a lot of force on the scissors, and it is necessary to cut each onion in several times according to the direction of root extension.

[0005]

However, in the prior art,
At the time of rooting the onions, since the roots were manually cut off with scissors, a considerable amount of force was required for the rooting work, and the hands were tired because the rooting work was performed continuously for a long time, It was a considerable amount of hard work. Further, in rooting work with scissors, one onion needs to be divided into several times and the scissors must be put in several times, so that there is a problem that the work efficiency is poor.

[0006] Therefore, an object of the present invention is to provide an onion rooting machine capable of performing the onion rooting operation easily and in a short time.

[0007]

SUMMARY OF THE INVENTION An onion rooting machine according to the present invention has a pair of brush rolls in a main body case, and the onion roots are sandwiched from above between the brush rolls to lower the roots. And a pair of pinching rolls arranged in close contact with each other at a position adjacent to one end side in the length direction of the root hanging device. A root cutting device capable of tearing off the root from the onion by sandwiching the root in a state of being hung downward by each brush roll, the brush roll and the pressing roll. Is provided with a power unit for driving the respective upper surfaces so that the upper surfaces thereof rotate inward with respect to each other.

[0008]

According to the onion root removing machine of the present invention, when the power unit is driven, the upper surfaces of the brush rolls of the root hanging device and the pinching rolls of the root cutting device are inside each other by the power unit. It is driven so as to rotate toward. Then, when the onion rooted portion is brought into contact between both brush rolls of the root hanging device in that state, the onion roots are drawn downward between both brush rolls by rotating each brush roll, Each of the roots can be drooped linearly. Then, in the root drooping device, the onions having the roots hanging down are laterally moved to the root cutting device side as they are, and the onions are transferred between the clamping rollers of the root cutting device. The drooping root is sandwiched between both clamping rolls, and both clamping rolls are rotated in close contact, so that the root of the onion is pulled between the closely contacted parts and forcibly torn off. Like

[0009]

Therefore, according to the onion rooting machine of the present invention, the roots of the onions can be drooped in a straight line simply by placing the rooted portion of the onions between the two brush rolls in the root hanging device. It is possible to remove the onion root easily by moving the onion laterally to the root cutting device side so that the root can be torn off by both clamping rollers. You can As a result, there is an effect that the rooting work of the onions can be performed with a relatively light work, and the efficiency of the rooting work can be significantly improved.

Housing chambers 11, 11 for housing power transmission members 43, 44 such as pulleys and belts of the power unit 25 are formed at both ends of the main body case 1 in the front-rear direction (arrow AB direction). .. Further, in the central portion of the main body case 1 in the front-rear direction, the left and right side plates 12,
12 is provided, and the space between the side plates 12, 12 serves as a roll installation portion 13 for installing the root hanging device 5 and the root cutting device 15.

As shown in FIGS. 2 and 3, the root hanging device 5 uses a pair of left and right brush rolls 21 and 21 which linearly hangs the root N extending from the lower end of the onion. There is.

Each of the brush rolls 21 and 21 is formed by arranging a large number of brushes 27 around a core member 26 in a radial pattern. The diameter of the brush roll 21 is relatively small (for example, a diameter of 5 to 7 cm) so that the root N of the onion can be pulled downward when the rooted portion of the onion is placed on the upper surface between the brush rolls 21 and 21. It is supposed to be).

Each of the brush rolls 21 and 21 is oriented in the front-rear direction (direction of arrow AB) at a position near the front side (arrow A side) in the roll installation portion 13 and the outer surfaces thereof are close to or substantially in contact with each other. It is arranged horizontally.
In addition, the brush rolls 21 and 21 are respectively attached to the shafts 2 supported by the front side support plates 41A and 41B of the main body case 1.
It is cantilevered by 2.22. The core material 26 of the brush roll and the shaft 22 are fixed.

As shown in FIGS. 2 and 4, the root cutting device 15 uses a pair of left and right pinching rolls 31A and 31B which act to tear off the root N of the onion.

Each of the pinching rolls 31A and 31B has a relatively small diameter (for example, a diameter of about 3 to 4 cm). As a material of the pinching roll, a steel material is preferable in terms of wear resistance, but a semi-hard rubber or plastic is preferable in terms of biting into the root. In this embodiment, one pressing roller 31A is made of steel and the other pressing roller 31B is made of semi-hard rubber. In addition, a plurality of narrow grooves 3 are formed on the outer peripheral surface of each pinching roll 31A, 31B.
8 and 39 are formed so that the tearing force of the root is increased.

Each of the pinching rolls 31A and 31B is disposed laterally in the roll installation portion 13 at a position closer to the rear side (arrow B side) in the front-rear direction and with the outer surfaces in contact with each other. In addition, each pinching roll 31
A and 31B are rear support plates 42 of the main body case 1, respectively.
It is cantilevered by the shafts 32A and 32B supported by A and 42B. The pinching rolls 31A, 31B
Are also fixed to the shafts 32A and 32B, respectively.

The pinching rolls 31A and 31B are
The valley groove portion between the two pinching rolls is the both brush rolls 21,
It is positioned so as to be located on the same straight line as the valley groove portion between 21 and at substantially the same height. Moreover, each pinching roll 31
The ends of A and 31B and the brush rolls 21 and 21 are arranged so as to be close to each other.

As shown in FIG. 2, the power unit 25 is a motor 40 and a power transmission member (pulley and belt) on the root suspending device side for transmitting the power from the motor 40 to the root suspending device 5.
43 and a root-cutting device-side power transmission member (pulley and belt) 44 that is transmitted to the root-cutting device 15. When the motor 40 is driven, the root drooping device-side power transmission member 43 drives the brush rolls 21 and 21 so that the upper surfaces thereof rotate inward, and the root-cutting device-side power transmission member 44. Each clamping roll 31A, 3
1B is driven such that the upper surfaces thereof rotate inwardly toward each other. Further, in this embodiment, the root-cutting device side power transmission member 44 drives only one of the two pressure rollers, but both pressure rollers 31A and 31B have mutual outer surfaces. Since it is in contact with, the non-driving side pressure roller 31B also rotates together with the driving side pressure roller 31A.

The motor 40 is attached to the rear side plate 14 of the main body case 1, and is turned on and off by a start switch 45.

In another embodiment, the root cutting device 15 may be modified as follows. That is, both clamping rollers 31
A transmission gear may be provided on each of the shafts 32A and 32B of the A and 31B to drive both clamping rollers. or,
In this embodiment, one pinching roll 31B is made of a semi-hard material.
Since the pinching roll 31B is relatively easily worn because it is made of (rubber or the like), when the pinching roll 31B is worn, it can be replaced with a new one.
When one of the two pinching rolls is a driven roll as in the illustrated example, the driven side pinching roll 31B can be adjusted in the contacting / separating direction with respect to the driving side pinching roll 31A. In this way, the contact pressure between the sandwiching rolls 31A and 31B can be adjusted. The method and operation of the onion root removing machine of the first embodiment will be described. First, the start switch 45 is turned on and the power unit 25 drives the brush rolls 21 and 21 of the root hanging device 5 and the root cutting device 15. As shown in FIGS. 2 and 3, while the pinching rolls 31A and 31B of FIG.
Place it in the valley between 1 and 21. At this time, the brushes 27, 27, ... Of the brush rolls 21, 21 are adapted to linearly extend the root N of the onion downward and hang it down. Subsequently, as shown in FIGS. 2 and 4, when the onion is laterally moved from the brush roll side to the pinching roll side, the root N of the onion comes to be sandwiched between the both pinching rolls 31A and 31B. At this time, the root N is pulled between the contact portions of the pinching rolls 31A and 31B and is torn from the onion body. As described above, in the onion rooting machine of the first embodiment, after the rooted portion of the onion is placed on the upper portion between the brush rolls 21 of the root hanging device 5, it is laterally moved to the root cutting device 15 side. Since the rooting work can be performed only by performing the rooting work, the rooting work can be extremely easy and the work efficiency can be greatly improved.

In the onion rooting machine of the second embodiment shown in FIG. 5, thin strings 49, 49 are spirally wound around the outer circumferences of the brush rolls 21, 21 of the first embodiment. Brush rolls 21,21 with this thin cord 49,49
When the brush rolls 21 and 21 rotate inward with respect to each other, the root of the onion placed between the brush rolls 21 and 21 is pulled downward by the brush 27, and the onions are spirally threaded 49, At 49, the brush rolls are automatically fed to the tip side of the brush rolls. Then, the onions transferred to the tips of both the brush rolls are automatically transferred to the upper part between the two pinching rolls 31A and 31B, and the rooting work is performed there. In the second embodiment, rooting work can be performed automatically simply by placing the onion on the upper part between the brush rolls 21 with the rooted part on the lower side. In addition, work efficiency is further improved. The other construction of the second embodiment is similar to that of the first embodiment.
