DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show a multi-film laying machine 10 in which a rotary working machine 11 is connected to the rear part of the tractor body, and a drug injecting machine 14 is provided between a tilling claw 12 of the rotary working machine 11 and a rear cover 13.
[0009]
The drug injector 14 is inserted into a slit 15 opened in the front-rear direction of the rear cover 13, and is arranged in a line at substantially equal intervals between the tilling claws 12, 12 arranged in parallel in the left-right direction. Yes. That is, by arranging the drug injector 14 within the rotation trajectory of the tilling claw 12, the overall length of the device can be shortened. Since the rear cover 13 has a slit 15, the rear cover 13 can be rotated without interfering with the medicine injecting machine 14.
[0010]
In addition, an electric pump 17 is mounted on the upper portion of the tool bar 16, and a medicine filled in a tank (not shown) is pumped up and pumped to the medicine injector 14. A side beam 18 is provided in the left-right direction at the rear portion of the toolbar 16, and a multi-film feeding portion 19 is installed at a lower rear position thereof.
[0011]
A roll of multi-film 20 is attached to the feeding portion 19, and the multi-film 20 is drawn from the feeding portion 19 as the multi-film laying machine 10 is pulled by the tractor. At this time, a pressing roller 21 is provided behind the roll of the multi-film 20 and the pressing roller 21 is lightly pressed against the roll of the multi-film 20 so that the multi-film 20 is stably fed out.
[0012]
On the other hand, a pressure reducing roller 22 is provided across the entire width of the tilling claw 12 between the tilling claw 12 and the multi-film feeding portion 19. The pressure-reducing roller 22 reduces the surface of the soil into which the medicine has been poured while being cultivated by the tilling claws 12 so that the unevenness of the bed is eliminated and the multi-film 20 can be laid easily and reliably.
[0013]
In addition, by compressing the soil immediately after sterilization with the suppression roller 22, the injected drug is uniformly distributed from the ground surface to a shallow position, and the drug is scattered before the multifilm 20 is laid. Can be prevented. The pressure-reducing roller 22 supports the weight of the multi-film laying machine 10 and also acts as a gauge wheel of the rotary working machine 11, so that it is not necessary to provide a separate gauge wheel, so that the overall length of the apparatus can be shortened.
[0014]
Further, arms 23 and 23 are provided on the left and right rear sides of the side beam 18, and a guide wheel 24 and a pressure reducing wheel 25 are provided on each arm 23. The left and right ends of the multi-film 20 fed from the feeding portion 19 are connected to the left and right ends. The guide wheel 24 and the pressure wheel 25 are pressed. The arm 23 is provided with a soil covering disk 26 and a sponge ring 27, and the soil covering disk 26 and the sponge ring 27 are selected and set by the processing method of the end of the multi-film 20.
[0015]
Further, earth removal discs 28 and 28 are provided at the left and right front positions of the tool bar 16, and the earth removal disc 28 is turned down and grounded as necessary to reach a position corresponding to the end of the multi-film 20. It is formed so that grooves can be continuously formed.
[0016]
Here, when the multifilm 20 is laid while disinfecting the field by the multifilm laying machine 10, the laying operation is performed by reciprocating a plurality of times from one end to the other end of the field. At the time of laying the first row, the covering soil disks 26, 26 are set on both the left and right arms 23, 23, and the sponge rings 27, 27 are flipped upward. In addition, the left and right earth removing disks 28, 28 are also set by being turned downward.
[0017]
In this state, while cultivating the field with the cultivating claws 12 of the rotary working machine 11, positions corresponding to both ends of the multi-film 20 are continuously grooved by the left and right soil removing disks 28, 28, The drug is injected into the soil cultivated by the drug using the drug injector 14. Subsequently, the pressure is reduced by the pressure roller 22 so that the unevenness is eliminated, and the multi-film 20 can be easily laid.
[0018]
Then, the multi-film 20 fed out from the feed-out portion 19 is pressed by the left and right guide wheels 24, 24, and both end portions of the multi-film 20 are laid in a concave shape at the groove forming portion by the earthing discs 28, 28. If soil is applied to the concave portion with the soil covering disks 26, 26 and then the pressure is suppressed with the pressure reducing wheels 25, 25, the left and right ends of the multi-film 20 are fixed by the soil covered with the soil.
[0019]
Thus, after the multi-film 20 of the first row is laid, the multi-film laying machine 10 is reversed and the laying operation of the second row is performed. At this time, since the multi-film 20 to be newly laid is superimposed on the other end of the multi-film 20 in the first row already laid, the covering disk 26 of the arm 23 on the first row side is flipped upward. Set the sponge ring 27. In addition, the soil removal disk 28 on the first row is also flipped upward.
[0020]
Then, the laying position is set so that the covered portion of the multi-film 20 in the first row can be covered with the end of the multi-film 20 in the second row. The multi-film 20 is laid while disinfecting. At this time, after the adhesive tape 30 is pulled out from the roll 29 attached to the end of the side beam 18, the first row of multi-films 20 and the second row of multi-films 20 are bonded together with the adhesive tape 30. The sponge ring 27 is pressed.
[0021]
On the other hand, the end of the non-laying side opposite to the multi-film 20 in the first row is grooved by the earthing disk 28, and the first row and the end of the multi-film 20 in the second row are fed out. Similarly, the soil is covered with the soil covering disk 26.
[0022]
In this way, a plurality of rows of multi-films 20 are sequentially laid, and adjacent multi-films are bonded with the adhesive tape 30 so that soil disinfection and multi-film laying are continuously performed over the entire field. Can be done automatically.
[0023]
Here, the rear cover 13 of the rotary working machine 11 rotates up and down depending on the amount of soil cultivated. As shown in FIG. 3, when the lower end of the rear cover 13 jumps upward, The height of the lower end portion of the rear cover 13 is set to be lower than the axial center of the pressure reducing roller 22 in contact with the front surface. This is because, when the height of the cultivated soil becomes higher than the axial center of the pressure reducing roller 22, the pressure reducing roller 22 stops rotating and pushes the earth, so that when the amount of soil increases, the rotation of the rear cover 13 is performed. This is to restrict the movement below the axial center of the pressure reducing roller 22 and press the soil by the rear cover 13 to keep the cultivated soil below the height of the pressure reducing roller 22 so that the pressure can be reduced. .
[0024]
The multi-film laying machine shown in FIGS. 4 and 5 will be described because it is not the gist of the present invention but is related. As shown in FIGS. 4 and 5, if both ends 22 a and 22 a of the pressure reducing roller 22 are formed to have a large diameter, the ground surface is pressed by the both ends 22 a and 22 a, and it corresponds to both ends of the multi-film 20. The position to do can be continuously grooved. Further, the side to be bonded by the adhesive tape 30 is compacted by pressing the covering portion from the upper surface of the multi-film 20, so that the adhesive tape 30 can be easily bonded and the soil removal disk 28 becomes unnecessary.
[0025]
It should be noted that the present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
[0026]
【The invention's effect】
As described above, the present invention Upon Ru provided a drug infusion device between the tilling claws and the rear cover of the rotary working machine, the infusion machine is provided is inserted through the perforated in has been slit in the longitudinal direction of the rear cover Therefore, the overall length of the apparatus can be shortened , the rear cover can be rotated without interfering with the medicine injecting machine, and the multi-film feeding section disposed behind the rear cover and the tilling claw Since the pressure-reducing roller is provided, the multi-film laying operation can be carried out easily and reliably by eliminating the unevenness of the bed by pressing the surface of the soil into which the chemical is injected while being plowed.
In addition, the position corresponding to both ends of the multi-film is continuously grooved by the right and left soil-discharging discs, and after the chemical is injected into the cultivated soil, the unevenness of the soil is eliminated by the pressure-reducing roller. The film can be easily laid.
[0027]
In addition, by pressing down the soil immediately after disinfection with a pressure reducing roller, the injected drug is evenly distributed to the shallow position from the ground surface, and the drug is scattered before the multi-film is laid. The multi-film fed out from the feed-out portion can be prevented from being pressed by the left and right guide wheels, and both ends of the multi-film are laid in a concave shape in the groove forming portion formed by the earthing disc. If the soil is applied to the part with a soil covering disk and then the soil is pressed with the pressure wheel, the left and right ends of the multi-film are fixed by the soil covered with the soil.
[0028]
Furthermore, in the present invention, the laying position is set so that the covering portion of the multi-film in the first row can be covered with the end of the multi-film in the second row, and the multi-film is disinfected as in the first row. When the adhesive tape is pulled out from the roll provided at the end of the side beam, the first row multi-film and the second row multi-film are bonded with the adhesive tape, and then pressed with the sponge ring, The end of the non-laying side opposite to the first row of multi-film is grooved by the above-mentioned earthing disc, and the end of the second row of multi-film is fed to the cover disc in the same manner as the first row. Therefore, soil disinfection and multi-film laying can be performed continuously over the entire field.
Thus, the workability at the time of laying the multi-film by injecting the medicine into the field is remarkably improved.
