Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling insect pests in crops.

[0002]

2. Description of the Related Art In the cultivation of crops such as rice, various control methods have been developed and implemented, but the main one is the use of pesticides. In addition, today, there is a tendency that pest-free control such as organic cultivation and pesticide-free cultivation is favored. Increasingly, biological control methods for removing weeds and pests by releasing them into paddy fields are gradually increasing.

[0003] However, among the biological control methods which are mainly aimed at controlling pests, they are effective when the crop is still short, but after the crop has grown to a high height, the pests also have an effect on the growth of the crop. As a result, there is a case where the effect cannot be expected after moving upward. A typical example of this is rice beetle on rice, and this pest is
While moving from the root of the rice to the leaf surface as the adult grows, the white leaves of the rice become damaged at the adult stage, causing serious damage such as severely stopping the growth of the rice.

[0004]

The problem is that pesticides must be used as a result for pests such as rice beetle that cannot be expected to have much control effect by biological control methods such as rice. Nevertheless, crop producers are still keen to provide markets that do not use pesticides. The present invention has been made in view of the above circumstances, and is capable of mechanically and physically exterminating pests such as rice beetles in the case of rice without using pesticides (known in the art). It is another object of the present invention to provide an apparatus for controlling insect pests, which makes it possible to provide crops that do not use pesticides to the market, which are different from so-called “mechanical control” and “physical control”.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the crop pest control device according to the present invention includes a collector having an opening (collecting port) and a rotor that rotates so as to squeeze the crop and take the pest of the crop into the collector. (Claim 1). Also, a rotor provided with a beater that circulates around the rotation axis radially outward of the rotation axis, and a rotor support that rotatably supports the rotor with the rotation axis supported along the ground. A frame, a collector provided with an opening facing a part of the outer periphery around the rotor on the rotor support frame side, and a pest of the crop being squeezed with the rotor to remove the pests of the crop to the collector. Rotation driving means for rotating the rotor so as to take in (claim 2).

[0006] With such a configuration, when the rotor is pressed against the crop while being rotated by the rotary driving means, the beater rakes the crop into the collector (cage, net, or case). And the beater may even hit the crop in the collector after this. Therefore, the pests (including not only adults but also larvae and eggs, etc.) attached to the crop are wrung by the blades of the rotor and taken into the collector. The rotor and the collector are a unit (one set), and this unit can be supported by the elevating means so as to be able to move up and down with respect to the apparatus main body.

[0007] In this manner, the height of the rotor can be appropriately changed with respect to the crop, so that the pests can be collected uniformly from the root of the crop to the tip of the crop, or from the height as required. Becomes possible. This is preferable because it leads to broadening the versatility of the type of crop, the type of pest, the execution time of pest control, the hardness of the ground, and the like. This elevating means also prevents the rotor or the like from hitting the ridge when the pest control device is moved near the ridge or the like (particularly when the device main body is made movable as described later). Is an effective means.

The rotor and the collector are formed as a unit, and this unit can adjust the degree of inclination of the rotation axis of the rotor with respect to the apparatus main body by the inclination adjusting means. In this way, even when the ground has a hard or soft difference or inclination, the rotation axis of the rotor is held horizontally, or the rotation axis of the rotor is intentionally inclined regardless of the state of the ground. Can be handled. A self-propelled traveling means is provided in the apparatus main body, and the rotor and the collector can be mounted on the apparatus main body as a unit as a unit (claim 5).

By doing so, it is needless to say that the pest control work can be made more efficient and the labor burden on the workers can be reduced. In addition to the self-propelled type, the main body of the device is capable of traveling freely and is towed or pushed by another traveling vehicle such as a tractor, or as having no traveling structure, such as a tractor. It may be configured to be detachable from another traveling vehicle. It is preferable that the collector is detachable from the rotor support frame (claim 6).

[0010] By doing so, there is an advantage that removal of the collected pests, replacement of the collector according to the pests, maintenance of the rotor and the collector, and the like can be performed easily and quickly. The opening in the collector facing the rotor has an inlet-side blade for contacting a beater that is going to enter the collector as the rotor rotates, so that the crops to be scraped are squeezed. Abuts a beater that is about to exit from this collector with the rotation of the rotor,
It is preferable to provide an outlet-side blade for preventing the pest once collected from flying out (claim 7).

In this case, there is an advantage that the crop can be prevented from being damaged by forming the beater of the rotor and the inlet side blade and the outlet side blade provided in the collector with a soft material such as rubber. .

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 are general views of an embodiment in which a crop pest control device 1 according to the present invention is provided for a vehicle-type device main body 3 provided with a self-propelled traveling means 2.

A headlight 14 is provided at the front end of the main frame 12. In contrast to the device main body 3, the pest control device 1 includes a collector 18 having an opening (collecting port) 30.
And a rotor 17 that rotates so as to squeeze the crop and take the pests of the crop into the collector 18 as a unit (one set).

That is, the lower frame 13 is formed on the basis of the rotor support frame 16 which is held at the front end of the lower frame 13 immediately behind the front wheel 6 so as to extend to the left and right sides.
In addition to the rotor support frame 16,
, A collector 18, and a rotation driving means 19,
In addition, an elevating means 20 and an inclination adjusting means 21 are added. As shown in FIGS. 3 and 4, the rotor 17 includes a beater support shaft 23 provided along a rotation axis, and a plurality of rotors 17 (see FIG. 3) radially projecting from the beater support shaft 23 in the radial direction. And four beaters 24 in the example)
By rotating the beater support shaft 23, the beater 24 moves around the rotation axis.

The beater 24 is made of a strip material such as soft rubber or soft resin, or a soft material such as a brush planted along the beater support shaft 23. Is screwed or riveted to the mounting plate 25 which is fixed to the mounting plate 25. It can be said that the screw structure is preferable in that the beater 24 can be easily replaced when it is damaged or worn. The rotor support frame 16 supports the rotor 17 so that its rotation axis (beater support shaft 23) is oriented along the ground G and is rotatable.

In the present embodiment, as described above, the rotor support frame 16 extends to the left and right sides of the main frame 12 of the apparatus main body 3 as a center. The other overhanging region supports each other rotor 17 and, therefore, to enable this, the left overhanging end and the lower side of the main frame 12, and the right overhanging end and the main A pair of bearing bodies 27 which are respectively opposed to each other are suspended at two places on the lower side of the frame 12. The collector 18 is provided on the rotor support frame 16 such that the opening 30 faces a part of the outer circumference (about half circumference) around the rotor 17. A cage-like material in which a filtering material 32 is attached to a tension frame 31 assembled in a cage is used.

The mounting position of the collector 18 with respect to the rotor support frame 16 is such that the collector 18 is positioned behind the rotor 17 when the apparatus main body 3 travels with the front wheel 6 directed forward. It is. In the rotor support frame 16, separate collectors 18 are attached to the left overhanging region and the right overhanging region. The filtering material 32 may be made of a hard material such as a metal or a hard resin (including a material having a certain degree of flexibility such as PP), a fabric, a synthetic fiber, and a soft resin. And the like. Needless to say, the mesh must be smaller than the pest to be controlled. In some cases, fine gauze-like openings may be used.

When the hard filter material 32 is used, the tension frame 31 can be eliminated. The collector 18 is detachable from the rotor support frame 16, and engages by fitting a hook 33 provided on the tension frame 31 into an engagement hole 34 provided on the rotor support frame 16. Or remove it. In the opening 30 of the collector 18, an inlet blade 36 is provided along the lower edge side, and an outlet blade 37 is provided along the upper edge side. Each of the inlet-side blade 36 and the outlet-side blade 37 is formed of a band material such as soft rubber or soft resin, or a soft material such as a brush planted along the beater support shaft 23.

The vertical positional relationship between the inlet blade 36 and the outlet blade 37 is determined by the relationship with the rotation direction of the rotor 17. That is, since the rotor 17 is rotated clockwise in FIG.
Penetrates into the collector 18 through the lower edge of the opening 30 (this is the entrance), and exits from inside the collector 18 through the upper edge of the opening 30 (this is the exit). Therefore, it is positioned as described above. When the beater 24 enters the collector 18, the inlet-side blade 36 comes into contact with the beater 24. Therefore, the crop T planted on the ground G is scraped into the collector 18 and is beaten by the beater 24 and the inlet-side blade 36 during the scraping. Therefore, the pests (including not only adults but also larvae and eggs) attached to the crop T are taken into the collector 18 by this ironing.

On the other hand, when the beater 24 exits from the inside of the collector 18, the exit side blade 37
4. Therefore, the collector 1
It is possible to prevent the pest once taken into the inside 8 from jumping out of the collector 18. The rotation drive means 19 is for rotating the rotor 17, and distributes rotational power taken out of the engine 7 via a power take-out shaft 38 to a distribution gear portion 39 connected to a front end of the power take-out shaft 38.
5 (see FIG. 5), it can be transmitted to the respective beater support shafts 23 of the left and right rotors 17 via the left and right distribution shafts 39a and 39b.

The lower frame 13 of the apparatus main body 3 is
As described above, it has an L-shape (see FIG. 1), and has a vertical rod 13a and a horizontal rod 13b. hand,
A shaft cover 40 that covers at least both left and right surfaces of the power take-off shaft 38 is provided. The power take-off shaft 38 includes a universal joint (not shown) at an appropriate position in the axial direction including a connection portion with the engine 7 and the distribution gear portion 39.
Is provided. This allows the power take-off shaft 38 to swing left and right within a predetermined range in the shaft cover 40 near the distribution gear 39 with the fulcrum near the engine 7 as a fulcrum, enabling the distribution gear 39 to move left and right. Accordingly, it is possible to cope with the angle adjustment by the inclination adjusting means 21 described later.

As shown in FIG. 5, a bracket 42 is fixed to a lower portion of the distribution gear portion 39. The bracket 42 is attached to a pivot 43 provided at the front end of the lower frame 13 so as to protrude forward. To be able to swing left and right. As shown in FIG. 1 and FIG.
Are the main frame 12 and the lower frame 1 of the apparatus body 3
A lifting drive 44 such as a fluid pressure cylinder is provided between the vertical rod 13b and the third horizontal rod 13b, and the horizontal rod 13b is vertically swingable with respect to the vertical rod 13a in the lower frame 13. I have.

That is, the lifting drive 44 is driven (expanded / contracted).
By doing so, the horizontal rod 13b swings up and down, and as a result, the rotor support frame 16, that is, the rotor 17 is raised and lowered. Note that the lifting / lowering drive 44 is connected to the power take-out shaft 38.
In a portion intersecting with the power take-off shaft 38, a connecting member 45 is used which escapes the interference with the power take-out shaft 38 by a forked body. The left and right balance can be balanced.

As shown in FIG. 2, the inclination adjusting means 21
The balancer weight 48 is provided on the upper surface of the rotor support frame 16 via the left and right driving means 47 so as to be movable left and right. Are provided so as to be able to swing left and right via a pivot 43 and a bracket 42 (see FIG. 5). Left and right driving means 4
Reference numeral 7 denotes a drive wheel 51 provided with a motor 50 on one end side (left side in FIG. 2), and a free wheel 52 on the other end side (right side in FIG. 2). Are connected to a weight carry car 54 on which the balancer weight 48 is loaded.

That is, by driving the left and right driving means 47 to move the weight carry car 54 right and left and stop it at an appropriate position, the left and right inclination of the rotor support frame 16 is changed. The inclination of the axis can be adjusted. next,
The operation of the pest control device 1 will be described. First, the inclination adjusting means 21 is driven as necessary to adjust the inclination of the beater support shaft 23 (rotation axis) of the rotor 17 with respect to the ground G to a predetermined value. The adjustment of the degree of inclination can be accurately adjusted by slightly differentiating the position of the weight carry car 54 in the left-right direction.

At this time, as shown in FIG.
Of the apparatus main body 3 may be sunk into soft ground, or one of the rear wheels 5 may ride on an inclined surface such as a ridge.
Irrespective of this, the beater support shaft 23 of the rotor 17 can be set substantially horizontally. This request can also be met when the beater support shaft 23 of the rotor 17 is intentionally inclined regardless of the state of the ground G (for example, when the degree of growth of the crop T varies). Next, if necessary, the lifting / lowering means 20 is driven to adjust the height of the rotor 17 from the ground G to the height at which the pests are to be removed from the crop T. This height adjustment can be accurately adjusted by making the amount of expansion and contraction of the elevation driving tool 44 slightly different.

When these adjustments have been made, the rotation driving means 19 is driven to rotate the rotor 17 clockwise in FIG. Further, the driving unit 2 is driven to move the apparatus main body 3 forward. In this manner, the rotating rotor 17 is pressed against the crop T, and the beater 24
Rushes into the collector 18 while squeezing the crop T,
In some cases, even after this, the beater 24 will hit the crop T in the collector 18. Therefore, pests (including not only adults but also larvae and eggs) attached to the crop T are taken into the collector 18.

It is also possible to use a method in which the vertical movement of the rotor 17 is repeated by the elevating means 20 while the apparatus body 3 is running, whereby the pests can be collected uniformly from the root of the crop T to the tip of the leaf. it can. Crop T is rice,
To give a specific example of a case where the pest to be controlled is a rice beetle, the rotor 17 is provided with four beaters 24, and each beater 24 has a thickness of 6 mm and a width (protruding dimension in the radial direction). A 70 mm soft rubber plate was used.
The total length in the left-right direction of the left and right rotors 17 was 2.7 m, and the rotation speed of the rotor 17 was 30 rpm.

Under these specifications, pest control using this pest control apparatus 1 was carried out at a time before the spikelets of the rice flowered, and a control rate of about 100% was achieved. Incidentally, the present invention is not limited to the above embodiment. For example, the number of beaters 24 attached to the rotor 17 can be increased or decreased as appropriate, and its shape, structure, material, and the like can be changed as appropriate. The relative relationship such as the rotation direction, the number of rotations, and the traveling direction of the rotor 17 (the traveling direction of the apparatus main body 3) can be made different from the above embodiment.

Also, as for other configurations, various changes, replacements, etc., of the detailed structure, member shape, member material, adopted mechanism and the like are possible. The target crop T and pests are not limited. For example, it is also possible to target trees, plants, flowers and the like. As shown in FIG. 7, the rotor 17 is in the shape of a rectangular tube or a cylinder having a polygonal cross section (in the illustrated example, hexagonal, but not limited to), and has a raking port 60 on a part of its outer peripheral surface. , The other outer peripheral surface is filter material 32
, And a beater 24 can be formed at a portion located on the rear side in the rotation direction as an opening edge of the scraping port.

Although not shown, the rotor 17 is also rotatably held by the rotor support frame 16 and is driven to rotate by the rotation driving means 19. Further, a structure that is supported by an appropriate apparatus main body 3 may be used. Such a rotor 17 has a structure that also serves as the collector 18 itself. In the illustrated example, the rotary shaft 61 is provided at the center of the rotor 17.
1 can be omitted.

[0032]

As is apparent from the above description, in the crop pest control apparatus according to the present invention, the crop is squeezed while rotating the rotor, whereby the pests adhering to the crop are collected in the collector. Therefore, even pests such as rice beetles in the case of rice can be mechanically and physically controlled without using pesticides. Therefore, there is an increased possibility that even crops that could not be harvested without using pesticides can be provided to the market without using pesticides.
