Description

[Detailed explanation of the invention] [Industrial application field] This invention removes withered and defective lower leaves of leafy vegetables such as spinach and komatsuna, regardless of the type, variety, or harvest season. The present invention relates to a leaf finishing machine for removing and finishing leaves without adversely affecting the quality of the leaves themselves.

[Conventional technology]

Conventionally, leafy vegetables such as those described above have been finished by manually removing dead or defective lower leaves immediately before packaging and shipping.

[The problem that the idea aims to solve]

Relying on manual labor in this way is extremely inefficient and does not meet the current need for cost savings through rationalization of agricultural work, and countermeasures are desired.

[Means to solve the problem]

In order to solve the above problem, this invention installed a drive pulley driven by a variable speed motor mounted inside the motor box on the outside of the wall on one side of the motor box, which is swingably supported on the frame. A belt is stretched between this driving pulley and a pair of driven pulleys so that the rotating directions of these driven pulleys are opposite, and a pair of rotating shafts to which these driven pulleys are fixed are attached to the motor box. They are supported by bearings attached to both sides, project outward from the wall on the other side of the motor box, and enter the main body of the working machine attached to the motor box. An elastic band consisting of a rubber string between the outer peripheries of a pair of disk bodies that are each connected to the support shafts of a pair of rotating disks that are placed opposite each other, and are attached to these support shafts parallel to each other at a certain distance. A plurality of strips are stretched substantially parallel to the support shaft, and the elastic strips between the opposing disc bodies are sequentially moved toward the gap and toward each other without interfering with each other. , a safety cover is attached to the operating machine main body to cover the outside of the disk body, and the upper half wall of the operating machine main body on the opposite side of the motor box is swingable via a hinge. an air intake hole is formed in a wall forming the one side of the motor box near a mounting portion of the motor, and the air intake hole is connected to the wall forming the other side of the motor box into the working machine main body. This paper proposes a leaf finishing machine with ventilation holes.

[Effect]

In the leaf vegetable finishing machine of this invention having the above-mentioned structure, the leaves are inserted into the gaps while rotating each disc body by the motor, and the withered lower leaves of the leafy vegetables are removed by the elastic strips. This is done by scraping off and removing the damaged lower leaves.

〔Example〕

Next, this invention will be explained with reference to the illustrated embodiment.

In FIG. 1, the leaf finishing machine of this invention mainly consists of a drive part A, a motor box part B,
Since it is roughly divided into the acting machine body part C, it will be explained in that order.

First, motor box 1 of motor box part B
The motor box 1 is supported on the frame 2 by using fastening members 3 such as bolts and nuts, and by loosening the fastening members 3.
To enable changing the angle of support to a frame 2.

A variable speed motor 4 serving as the output end of the drive portion A is accommodated in the motor box 1, and its drive shaft 5 is protruded out of the wall 6 on one side of the motor box 1, and its end drive pulley 7
can be installed. Driven pulleys 10 and 11, which are driven by belts 8 and 9 from the drive pulley 7, are arranged along opposite inner walls of the motor box 1. 2 bearings each 1
2, 13, 14, and 15, and are fixed to mutually parallel rotating shafts 16 and 17. These rotating shafts 1
6 and 17 are projected outward from the wall 18 on the other side of the motor box 1, and are connected to the working machine main body portion C.
is inserted into the acting machine main body 19 of. In addition, since it is necessary to rotate these rotating shafts 16 and 17 in opposite directions, one of the belts 8 and 9 transmitting power from the drive pulley 7 to the driven pulleys 10 and 11, for example, the belt 9.
In this case, the idler 20 is placed on the slack side of the belt 9 to prevent the belts from contacting each other on the tension side and the slack side and causing wear. It is effective to route it through the network (see Figure 2).

As shown in FIG. 3, inside the working machine body 19, there are a pair of support shafts 2 that are disposed opposite to each other with a gap between them.
1 and 22 are supported, and these support shafts 21 and 2
2 are coupled to the rotating shafts 16 and 17, respectively. These support shafts 21 and 22 are provided with a pair of disc bodies 23, 24, 2 parallel to each other at a constant interval.
5 and 26 are attached, and these disk bodies 2
Elastic strips 29, 30 such as rubber cords are arranged approximately parallel to the spindles 21, 22 at appropriate intervals between the outer peripheral edges of the rotary disks 27, 28 constituted by the rotating disks 27, 28. The elastic strips 29, 30 of the rotary disks 27, 28 are
As the support shafts 21 and 22 rotate, they sequentially move toward the gap without interfering with each other.

As shown in FIG. 4, openings 31 and 32 are formed in the acting machine main body 19 above and below the gap between the rotary disks 27 and 28.
In the upper opening 31, the disk body 23,
a safety cover 33 that covers the outside of 24, 25, and 26;
34 is attached to the working machine main body 19 to ensure safety during work. Further, the upper half wall 35 on the outside of the main body 19, that is, on the opposite side of the motor box 1, has a hinge 36 as shown in FIG.
By configuring the rotary disks 27 and 28 to be swingable, it is convenient for repair and inspection of the rotary disks 27 and 28.

Furthermore, in order to prevent the motor 4 from overheating, an air intake hole 37 is formed in the wall 6 near the mounting area of the variable speed motor 4 of the motor box 1 in FIG. The wall 18 on the other side is formed with a ventilation hole 38 that communicates with the interior of the working machine main body 19, whereby the air flow generated by the rotation of the rotary disks 27, 28 is improved. are formed in the air intake hole 37, the inside of the motor box 1, the ventilation hole 38, and the inside of the operating machine body 19, so that the variable speed motor 4 can be cooled by this air flow.

When using the leaf finishing machine of this invention having the above-mentioned configuration, as shown in FIG. When inserted into the gap between 28, unnecessary lower leaves are scraped downward by the elastic strips 29, 30.

Normally, with the configuration described above and illustrated, the leaves 39 are inserted through the upper opening 31 of the main body 19, and the unnecessary lower leaves are allowed to fall through the lower opening 32. Depending on the type of leaf, it is also possible to loosen the fastening member 3 and insert the leaf from the side in a rotated state as shown in Fig. 8 to remove the lower leaves. be.

[Effect of idea]

According to this invention, although the mechanism has an extremely simple structure, by adopting a variable speed motor, it can adapt to differences in the degree of flexibility of leaves depending on the type and variety of leafy plants, as well as the harvesting period, etc. Because only unnecessary lower leaves can be efficiently removed without damaging the vegetables, it is extremely effective in quickly pre-shipping vegetables that require freshness. Since the motor can be cooled by the airflow generated by the rotation of the body, it is practically effective in that it can be used continuously for a long time.Furthermore, with this invention, the motor box can be swung on the frame. Since the motor box is supported, the motor box part including this motor box rotates together with the driving part and the main body part of the working machine to remove the leaves from the side during the work of removing lower leaves, as shown in Figure 8. This has the practical effect of being able to work in a manner of insertion.
