Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic cutting device for automatically cutting tendrils attached to seed coats of peanuts, for example.

[Prior art] For example, when peanuts are harvested from the field, tendrils are attached to the surface of the seed coat.In order to process the seed coat, these tendrils must first be removed from the surface of the seed coat. It won't happen. Conventionally, as a cutting device for removing tendrils attached to the surface of the seed coat, for example, as shown in FIG.
．． 1 is rotated in the direction of the arrow, and a partition plate 4.4 is placed on the upper surface of these cylindrical members 1.1 with a gap 3.3 large enough to prevent the seed coat 2 of peanuts or the like from passing through. The seed coat 2 with the tendrils 5 attached is placed on the surface of the circular member 1.1 surrounded by the partition plate 4.4, and the sixth
As shown in the figure, as the cylindrical member 1.1 rotates, the tendrils 5 attached to the surface of the seed coat 2 are drawn out from the gap 3 and brought close to the outside of each of the partition plates 4.4. This tendon 5 is cut off by a so-called steel 6 which is arranged as such and rotates while contacting the surface of the cylindrical member 1.1.

In such a device, the seed coat 2 with tendrils 5 on the surface is introduced into the device, and after a predetermined time period required for all the tendrils 5 of the seed coat 2 to be removed, the seed coat 2 is removed as shown in FIG. Then, a so-called extrusion blade 7 was moved along the surface of the cylindrical member 1.1 in the axial direction to collect the seed coat 2 from which the tendrils 5 had been removed.

[Problems to be Solved by the Invention] However, in the conventional vine cutting device as described above, the extrusion blade 7 is moved along the surface of the cylindrical member 1.1 in the axial direction to collect the seed coat 2. When doing so, there was a problem in that the extrusion blade 7 broke the shell of the seed coat 2 of peanuts or the like. That is, the seed coat 2 with tendrils 5 is carried to the partition plate 4.4 by the cylindrical member 1.1 having a large coefficient of friction on the surface, lies there, and at this joint is pushed out by the extrusion blade 7 into the cylindrical member 1.1. Because the shell is forced out against the friction of 1, breakage of the shell frequently occurs.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, the present invention aims to provide an automatic seed coat tendril cutting device that does not damage the surface of the seed coat and is suitable for mass processing of seed coats in assembly lines. be.

This is achieved by an automatic seed coat vine cutting device which is specially designed to cut out the seed coat vines by causing the seed coat vines to be removed. Moreover, the object of the present invention is further characterized in that the plurality of disks of the vine cutting means are coaxially arranged in a spiral manner, and the plurality of disks sequentially pass through the plurality of slits of the seed coat introducing tube. This is achieved by an automatic seed coat vine cutting device that is characterized by:

[In other words, the above-mentioned automatic seed coat vine cutting device has a disc having a plurality of notches on its circumference for inserting the vines, which is formed on the circumferential surface of the seed coat introducing tube. An automatic seed coat vine cutting device that does not damage the surface of the seed coat because the seed coat passes through a slit that is large enough to not allow the seed coat to pass through, and the seed coat tendrils are cut off during the passage. It becomes possible to provide. In addition, by making the plurality of disks pass through the plurality of slits in the seed coat introduction tube in sequence, the seed coat can be automatically moved inside the seed coat introduction tube, and the seed coat from which the tendrils have been removed can be continuously transferred. Therefore, it becomes possible to provide an automatic seed coat vine cutting device suitable for mass processing by assembly line operations.

[Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, two shafts 11 and 12 are rotatably mounted in parallel in the lateral direction in the figure on a base 10 constructed of, for example, a steel frame. That is, these two shafts 11 and 12 are mounted on bearings 13 and 13 fixed on the obliquely assembled steel frame of the base 10.
Supported by 14. Then, one end of the above two shafts, that is, the upper shaft 11 (the right end in FIG. 1)
A so-called transmission 15 is connected to the , and this transmission 15 converts the driving force transmitted from a driving force source, for example, an electric motor 16 via a belt 17, into rotation in a predetermined direction and speed. That is, the upper shaft 11 is rotated in the direction shown by the arrow in the figure. In addition, the upper shaft 1
A gear 18 is attached to the gear 1, and this gear 1 meshes with a gear 19 attached to the right end of the other of the two shafts, that is, the lower shaft 12, so that the two shafts, that is, the upper shaft The shaft 11 and the lower shaft 12 rotate in opposite directions (the upper shaft 11 is clockwise and the lower shaft 12 is counterclockwise) and at a constant speed, as shown by the arrows in the figure. ing.

In addition, in FIG. 1, a cylindrical seed coat introduction tube 20 made of, for example, an iron tube is arranged approximately at the center of the base 10 constructed by assembling the steel frame, and is rotatably supported. . That is, both ends of the seed coat introduction tube 200 are fixed to the upper shaft 11 via substantially cross-shaped support arms 21, so that they rotate together with the rotation of the upper shaft 11.

As shown in the figure, the surface of such a cylindrical seed coat introducing tube 20 has enough space along its circumference to pass through the vines 101 of the peanut seed coat 100 to be removed, but the seed coat is 100 has a plurality of slits 22 with a width that cannot be passed through. In this embodiment, ten slits 22 are provided on the surface of the cylindrical seed coat introducing tube 20.
The slits 22 are spaced apart from each other by a predetermined angle on the circumferential surface of the introduction tube 20, that is, are arranged spirally on the circumferential surface.

Furthermore, at the open end of the seed coat introducing tube 20 at the left end in the figure,
A funnel-shaped hopper 23 is provided for introducing the peanut seed coat 100 from which the tendrils 101 are to be removed into the tube.On the other hand, at the open end of the seed coat introducing tube 20 at the right end in the figure, the peanut seed coat 100 from which the tendrils 101 are to be removed is placed. In order to bring out the seed coat 100 outside the tube,
A so-called take-out chute 24 is provided on the side.

At approximately the center of the base 10 constructed by assembling the steel frame, a seed coat 100 is placed in parallel with the seed coat introducing pipe 20.
A so-called vine cutting means is provided for cutting off the tendrils 101, and this vine cutting means has a plurality of disc-shaped blades 25 on the lower shaft 12 rotatably provided on the base 10. installed and configured. That is, there are ten disc-shaped blades 25, each of which is eccentrically arranged at equal intervals at positions corresponding to the ten slits 22 formed on the surface of the seed coat introducing tube 20. These 10 blades 25 are arranged so that they are different from each other by a predetermined angle) 1 [n order, that is, in a spiral shape. Therefore, as shown in FIG. As the side shaft 12 rotates, these disk-shaped blades 25 sequentially pass through the slit 22 and into the seed coat introducing tube 20. The positions of these plates 25 and slits 22 are as follows:
Needless to say, the rotation is adjusted in synchronization with the rotation of the upper shaft 11 and the lower shaft 12.

Further, as shown in the figure, this disk-shaped blade 25 has a plurality of notches 26 formed on its circumference for fitting the tendrils 101 of the peanut seed coat 100 therebetween. The cut grooves 26 are formed to open obliquely in the direction of rotation from the center of the disc so that the tendrils 101 can be easily inserted therebetween. Each time this disc-shaped blade 25 passes through the inside of the seed coat introduction tube 20 through the slit 22 as it rotates, the tendril 101 of the peanut seed coat 100 is fitted into the cut groove 26,
The vine 101 is cut off. Further, it is desirable that the cut portion of the cut groove 26 and the tip of the disk-shaped blade 25 be formed with a slight roundness so as not to damage the surface of the peanut seed coat 100 due to its rotation.

Next, regarding the operation of the automatic seed coat vine cutting device described above,
This will be explained below using FIGS. 3(a) and (b) and FIGS. 4(a) and (b). First, in FIG. 1 or FIG. 2, peanut seed coat 100 whose vines 101 are to be removed is supplied to the funnel-shaped hopper 23 and introduced into the seed coat introducing tube 20. This seed coat introduction tube 20 rotates in the direction shown by the arrow, and the disk-shaped blade 25
The lower shaft 12 to which it is attached also rotates, and the ten disc-shaped blades 25 sequentially pass through the seed coat introducing tube 20 through the slits 22. At this time, as shown in FIGS. 3(a) and (b), the vine 101 of the peanut seed coat 100 whose vines are to be removed fits into the cut groove 26 formed on the circumference of the disc-shaped blade 25. Include. Thereafter, as the seed coat introduction tube 20 rotates, the disc-shaped blade 25 also rotates, and as shown in FIGS. 4(a) and 4(b), a notch is formed on the circumference of the disc-shaped blade 25. The groove 26 passes through the outer wall of the seed coat introducing tube 20, and at this time, the slit 22 is sufficient to allow the tendrils 101 of the peanut seed coat 100 to pass through, as described above, but the seed coat 100 does not pass through. Since the vine 101 has such a convergence that it cannot be removed, the vine 101 is separated from the peanut seed coat 100 and passed through the slit 22 while being fitted into the cut groove 26 and removed. That is, the peanut seed coat 100 remains inside the seed coat introducing tube 20, and
The vine 01 is cut off and taken out to the outside, and only the seed coat 100 of the peanut from which the vine has been cut can be recovered from the above-mentioned removal tray 24.

Further, in the above embodiment, as described above, the disc-shaped blades 25 are arranged one after the other at a predetermined angle, that is, in a spiral shape. Therefore,
The disc-shaped blade 25 is configured to pass through the seed coat introducing tube 20 one after another as the lower shaft 12 rotates, so that the disk-shaped blade 25 is configured to pass through the seed coat introducing tube 20 one after another as the lower shaft 12 rotates. The peanut seed coat 100 is automatically pushed out from the hopper 23 to the outlet by the action of the blade 25, and the peanut seed coat 100 with the tendrils cut off is sequentially sent out to the take-out chute 24.

Further, according to various experiments conducted by the inventor, the automatic vine cutting device described above has a seed coat introduction tube 20 of 30 to BO
The most suitable operation was obtained when operating at a rotational speed of about rpm. When rotated at this rotational speed, the peanut seed coat concentrates on the inner wall of the seed coat introducing tube 20 at about 45 degrees, and the angle θ formed by the upper axis 11 and the lower axis 12 shown in FIG. 2 is 45 degrees. It is desirable to keep it at a certain level.

Further, when the rotational speed of the seed coat introducing tube 20 is further increased, it is necessary to reduce the angle θ. Further, in the above embodiment, both the seed coat introducing tube 20 and the blade 25 are rotated, but, for example, only the blade 25, that is, only the lower rotating shaft 12 may be rotated. However, when only the blade 25 is rotated, the agitation of the seed coat 10 inside the seed coat introducing tube 20 becomes insufficient compared to when both blades are rotated, and the ability to cut off the tendrils 101 is somewhat inferior. , it is desirable to rotate both.

Further, in the above embodiment, the disk-shaped blade 2
Although the number of 5's has been described as ten, the present invention is not limited to this, but the same effect as the present invention can be obtained by changing the number as necessary or configuring other structures as appropriate. It is clear that it can be done.

[Effects of the Invention] As is clear from the above description, the present invention provides an extremely excellent and practical seed coat vine that does not damage the surface of seed coats or chew the shells of peanuts, etc. We can provide an automatic cutting device for this purpose. Further, according to the present invention, it is further possible to continuously collect the seed coat from which the tendrils have been removed, and it is possible to provide an automatic seed coat tendon cutting device that is particularly suitable for mass processing by assembly line operations. It exhibits an excellent effect.
