Description

[Detailed Description of the Invention] The present invention relates to an apparatus that can efficiently remove burdock roots.

Immediately after harvesting, burdock roots have roots extending over the entire outer surface of the burdock root, and since this would harm the product value, the roots were removed after washing with water before shipping.

In the first place, the thickness and length of burdock root is uneven, so it is difficult to efficiently remove the roots. As shown in Figure 1, the roots of the burdock root were removed by passing the burdock root 9 in hand one by one through a roller 8 on which a loop-shaped thread T was implanted, which was driven by a motor 6. In the contact area, the hanging direction of the burdock 10 and the rotating direction of the roller 8 are the same, so not only can the burdock not be removed cleanly, but it also takes a long time, about 4 hours, to process 300 to 9 burdock rootlets. It was necessary.

To explain the present invention with a side view in Fig. 2 and a plan view in Fig. 3, for example, on the same plane as the burdock supply table 1, from the vicinity of the rear edge B toward the direction C, which is the rear of the device, An endless belt 2 is provided that moves at a speed of about 1 m (seconds).

Although not shown, a drive device is connected to either the pulley 11 or 12.

Note that the belt tension pulley 13 may be provided as necessary.

On the outer peripheral surface of the endless belt 2, as shown in FIG. One end of the endless belt 2 on the opposite side to the moving direction is supported by a screw 14.

Burdock holding plate 3.3', 3"...20~40
Install them at an appropriate interval of about cw1.

Near the rear edge B of the burdock supply table 1, rollers 4 and 5 with a diameter of about 10 (about 771 mm) are provided above and below the endless belt 2.

Small holes are made at intervals of about 5 to 10 cm on almost the entire outer periphery of these rollers, and a thread or thread bundle of water-based nylon or other suitable rigidity is inserted into a loop γ with a diameter of about 5 Crn.
, γ', and fix it in this small hole by so-called beading.

Then, the loop γ of the roller 4 and the loop 7' of the roller 5 are arranged so that they are in contact with each other or are spaced apart from each other so that there is a slight gap between them.

The rollers 4 and 5 are rotated uniformly at a high speed of about 1500 revolutions (minutes) so that the direction of rotation of the side facing the endless belt 2 is opposite to the direction of movement of the endless belt.

Note that the drive device is not shown in detail in the drawings.

The inner angle A between the rollers 4 and 5 and the endless belt 2 is 5
The angle is preferably 0 to 85 degrees, preferably 60 to 80 degrees.

Since the present invention is constructed in this way, the endless belt 2
The burdock holding plates 3, 3', 3//... provided in the If the tip of the burdock (the side without leaves) is brought out from the burdock supply table 1 to the stop of the endless belt 2, it will inevitably be sandwiched between the burdock holding plates 3 and move together with the endless belt 2.

At this time, since the tip of the burdock is relatively thin, even if it bends a little, the endless belt 2 and the burdock 9 are separated by an internal angle of about 20 degrees and move.

Then, the fly 9 passes between the rollers 4 and 50, which are rotating at high speed in the opposite direction to the endless belt 2.

Since the tip of the flycatcher 9 is placed first, it is rubbed by the loops γ and 1' of the rollers 4 and 5 from the direction opposite to the direction in which the beard roots 10 grow (the direction in which they hang down), so that the roots of the beard are rubbed. It can be removed cleanly from the root.

In the present invention, the roller 4°5 is diagonal to the endless belt 2Llc at an angle of 50 to 85 degrees, so as shown in FIG. Since the burdock is in contact with the burdock at a right angle, the tip of the burdock that is separated by the burdock holding plate 3 will not be unnecessarily bent.

However, if the angle is 85 degrees or more, the tip of the burdock may bend too much and be cut, as shown in F, which is not desirable.

Furthermore, if the angle is less than 50 degrees, the frictional force of the rollers 4 and 5 as shown in H will cause many accidents of bending too much and breaking.

Since the burdock holding plates 3, 3', 3//... are separated from the endless belt 2 again at the pulley 12, the burdock automatically falls.

According to the device of the present invention, for example, it is possible to remove burdock roots from approximately 300 kg of burdock in 30 to 40 minutes with high efficiency, more completely and cleanly than with conventional methods, and it is also possible to remove burdock roots in a high-speed rotation loop. Since the entire surface of the burdock is rubbed with the threaded rollers 4 and 5, unexpectedly good results can be obtained, such as the need to wash the burdock with water, which was indispensable in the past, so it is extremely effective in practical use. be.
