Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for removing the roots of vegetables such as enoki mushrooms together with attached sawdust, dust, soil, etc.

[Conventional technology]

Traditionally, when producing processed foods using bottle-grown enoki mushrooms, the roots of the mushrooms grown in the cultivation area, where sawdust is attached, are first cut by hand and then processed. Ta.

[Problem to be solved by the invention]

However, in the conventional method, the root part is cut by a person with a knife, etc., so the cutting position is not constant, and parts that can be used for products are also cut, or sawdust etc. are left between the stems of enoki mushrooms. In some cases, the processing step may proceed with some residue remaining.
Enoki mushroom yields and processing efficiency were poor, with sawdust mixed into processed products, and work efficiency was extremely poor.

Therefore, the present invention is intended to solve the above-mentioned problems.The purpose of the present invention is to cut the stem part of the enoki mushroom by hitting the root part of the enoki mushroom with a plurality of rotating members in the middle of the transportation line of the transportation device for enoki mushroom. By creating an automatic device that can remove only the root part along with deposits such as sawdust, and also remove deposits caught between the stems, we have improved the yield in the processing process of enoki mushrooms. The aim is to significantly improve processing efficiency and work efficiency.

[Means to solve the problem]

In order to solve the above problems, the measures taken by the present invention are as follows:
A conveyance device for moving the enoki mushrooms in a predetermined conveyance direction and a rotation unit for processing the roots of the enoki mushrooms conveyed by the conveyance device are provided. The rotary unit is equipped with a conveyance belt driving means to move the root of the enoki mushroom in the direction, and a plurality of conveyance containers to receive and hold the root of the enoki mushroom in a state in which the root of the enoki mushroom protrudes on the conveyance belt in a direction perpendicular to the conveyance direction. a plurality of rotary members for impacting the root portion of the enoki mushroom with a tip side surface having a width smaller than the diameter of the stem portion and extending substantially parallel to the stem portion of the enoki mushroom, and a rotational drive means for rotating the rotary members; It is equipped with the following.

Here, the rotating members have a common rotating shaft parallel to the conveyance direction, and the rotating members are arranged in the axial direction of the rotating shaft with angles shifted in the rotational direction of the rotating shaft. In this case, it is desirable to arrange the rotating members at equal angular intervals in the rotational direction of the rotating shaft and at equal intervals in the axial direction of the rotating shaft.

Further, instead of the above, the rotation axis of the rotation member may be made perpendicular to the conveyance direction.

Furthermore, two sets of rotation units whose rotation members can rotate in opposite directions may be sequentially installed along the conveyance direction.

[Effect]

According to this means, when the enoki mushrooms are placed in the transport container with their roots protruding, the enoki mushrooms are transported in a predetermined direction as the transport belt moves, and the plurality of rotating members rotated by the rotation drive means Each tip hits the root part of the enoki mushroom.

Here, the rotating unit is positioned and fixed in advance so that the tip of the rotating member hits only the root portion. The plurality of rotating members of this rotating unit are arranged at different angles in the direction of rotation of the rotating shaft, so the tips of the rotating members hit the root part at different times one after another, and the movement of the transport container The collision position also moves little by little.

In this way, the root portion of the enoki mushroom is removed along with any adhering matter such as sawdust due to the collision of the rotating member. In this case, each rotating member has a tip side with a width narrower than the diameter of the root, and these collide with the root separately at different times, so that the stem of the enoki mushroom is not subjected to an unnecessarily large impact. damage to the parts can be prevented. Furthermore,
The impact of the tip of the rotating member can also remove deposits such as sawdust caught between the stalks of the enoki mushroom, and the yield and processing efficiency in the enoki mushroom processing process are improved compared to the conventional technology. Furthermore, by automating the root processing work, work efficiency is significantly improved compared to conventional methods.

In addition, even when rotating members having rotational axes perpendicular to the conveyance direction are arranged, each rotating member moves on a concentric circle around the rotational axis and collides with the roots of the enoki mushroom, resulting in the above-mentioned effect. A similar effect can be obtained.

Furthermore, if two rotating units are installed sequentially in the conveyance direction and the rotating members of these rotating units are rotated in opposite directions, the roots of the enoki mushrooms should be struck from a predetermined direction in one rotating unit. However, the other rotating unit can be installed so that the root part of the enoki mushroom is struck from the opposite direction. Therefore, due to the impact in one direction in the first rotating unit, the stem of the enoki mushroom flows in one direction, and then in the second rotating unit, it is impacted in the opposite direction, causing the roots and attached substances to can be removed more reliably. In addition, by adjusting the positional relationship of the rotation arcs of the two rotation units,
It is possible to make the length of contact between the tip and the root of the rotating member more uniform depending on the size of each rotation arc.

FIG. 3(a) is a front view of the actual structure of this embodiment as seen from the direction of arrow C in FIG. Figure 3 (
Shown in b). Here, the enoki mushrooms are placed on the transport cup 12 and held by the holding chain conveyor 45, but the rotation shaft 43 of the second rotation unit 40 is set at a position slightly shifted downward from the horizontal position of the enoki mushrooms. has been done. On the other hand, the rotation shaft 23 of the first rotation unit 20 is set to be slightly shifted upward from the horizontal position of the enoki mushrooms placed on the transport cup 12. In addition, each of the first rotation unit 20 and the second rotation unit 40 has a rotation shaft 23.43 on the rotation shaft 23.

First, it is struck from above by the rotating member 24 of the first rotating unit 20, and then it is struck from below by the rotating member 44 of the rotating unit 40. The root of the enoki mushroom that is hit by the rotating member 24 is pushed downward and the stem of the enoki mushroom also bends downward, so by hitting it from below in this state, it is more completely bent than before. It is possible to remove attachments between root parts and stem parts. Furthermore, since the rotation radius of the rotating member 24.44 cannot be increased indefinitely due to the structure of the device, the plate pieces 24a, 44.
The length of a varies, and the root portion cannot be completely removed to a uniform length. However, as shown in Fig. 4, by combining two rotating units 20 and 40 and slightly shifting the rotating shaft 2343 up and down from the root of the enoki mushroom, the length of the root to be removed can be made sufficiently uniform. It can be done.

By using this processing device, work efficiency is greatly improved compared to the conventional method of manually cutting the roots, and it is also possible to remove deposits caught between the stems. Moreover, since there is no risk of misalignment of the cutting position or damage to the stems of the enoki mushrooms, the yield and processing efficiency are also improved.

In this embodiment, two rotation units, the first rotation unit 20 and the second rotation unit 40, are provided, but even if only one rotation unit is installed, the basic effects of the present invention can be sufficiently obtained. I can do it.

Furthermore, in order to keep the position of the enoki mushrooms on the transport cup 12 constant, the transport cup 2 is actually installed diagonally and is provided with a stopper that stops the root portion at a fixed position.

<Second Embodiment> Next, a second embodiment of the root treatment device of the present invention will be described with reference to FIG. In FIG. 5, the same reference numerals are given to the parts having the same structure as those shown in FIG. 1, and the explanation thereof will be omitted.

In this second embodiment, instead of the rotation unit of the first embodiment, a rotation disk 61 is mounted on the frame 21 as a rotation unit 60, and is directly connected to the rotation motor 22 and its rotation shaft. Plate pieces 62 are vertically fixed on the plate 61 so as to be arranged in parallel in the diametrical direction of the rotary plate 61 and protrude toward the enoki mushrooms on the transport container 12.

In this rotating unit 60, parallel plate pieces 62 rotate in the circumferential direction as a rotating plate 61 rotates. Therefore, by setting the center axis of the rotary plate 61 above or below the position of the transport cup 12, the side surface of the plate piece 62 can be made to impact against the root part of the enoki mushroom in the rotational direction. . Therefore, as in the first embodiment, the root portion can be removed together with the deposits. Moreover, as the enoki mushrooms move in the transport direction, the direction of impact changes along the rotating part, and unlike the first embodiment, by making the lengths of the plate pieces 62 the same, the plate pieces 62 and Since the length of collision with the roots of enoki mushroom can be set to a completely constant value, more efficient and uniform removal action can be expected.

In this embodiment, the plate pieces 62 are arranged in parallel in the diametrical direction on the rotating disk 61, but the plate pieces 62 are arranged and fixed at different angles on the rotating disk 61 at different angles. In this case, each plate piece 62 hits the root portion at different times, so that no large impact is applied to the root portion as in the first embodiment.

Further, in this embodiment as well, it is possible to install two rotation units as in the first embodiment and to rotate the plate pieces 62 in the opposite direction to further improve the removal efficiency.

[Effects of the Invention] As explained above, the present invention installs a rotation unit in the middle of a conveyance device and rotates around the rotation axis of this rotation unit, thereby removing the enoki mushroom roots held in the conveyance container. Since it is characterized by installing a plurality of rotating members that impact the parts, the following effects are produced.

■ Multiple rotating members fixed in parallel on the rotating shaft,
Since multiple impacts can be applied separately with the narrow side of the tip, only the roots and their attachments can be removed without applying a large impact to the roots of the enoki mushroom.
It is also possible to remove deposits between the stems. Therefore, the yield, treatment efficiency, and work efficiency in treating the roots of enoki mushroom can be significantly improved.

■ When rotating members are arranged at different angles and intervals along the axis of rotation, the rotation of the rotating member causes multiple plate pieces to collide with the root at different times, reducing the impact on the rotating member. (can do.

■ If two sets of rotating units are installed and the rotational directions of the rotating members are set in opposite directions, deposits can be removed more completely and the length of the part to be removed can be made uniform. Therefore, processing efficiency can be further improved.
