Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an irrigation tube laying device for laying an irrigation tube on the upper surface of a ridge.

Conventional technology Conventionally, the irrigation methods for cultivating crops in greenhouses include a method in which sprinklers etc. are used to irrigate the entire crop from above, and a method in which water is passed through an irrigation tube installed at the top of the ridge. There is a method of watering the root part of the crop through the hole formed.

Here, the irrigation tube is generally installed manually after the ridges have been shaped, and the ridge shaping and the irrigation tube installation are performed in separate steps.
Furthermore, when covering the ridges with multi-film, the ridges are shaped in the first step, irrigation tubes are laid in the second step, and the multi-film is covered in the third step.

Problems that the invention aims to solve: The irrigation tubes are laid in a separate process after the ridges have been shaped, which is time-consuming. In addition, because the irrigation tubes are laid by workers walking along the sides of the ridges, they tend to twist easily, so when laying them in wide ridges, it is important to lay them right in the center of the ridges. is difficult. In order to untwist an irrigation tube installed in a wide ridge, a worker must step into the ridge and perform repair work to erase footprints left on the surface of the ridge.

In addition, when covering the ridges with multi-film,
The number of work steps is three, which is extremely time-consuming and reduces work efficiency significantly.

For this reason, as seen in Japanese Utility Model Application Publication No. 48-9539, a sheet covering work machine is connected to the rear of the tillage work machine, and a reel containing a wound irrigation hose is installed to perform ridge-building, etc. There is a system in which irrigation hoses are installed and sheets are covered at the same time as the work is carried out.

However, with this type of irrigation hose, there is no guide part for the irrigation hose to the ground surface, so there is variation in the installation position. Therefore, when installing a irrigation hose on the upper surface of a ridge, there is a problem that its position cannot be determined.

Means for Solving the Problem A tilling section for cultivating the field and a ridge shaper for shaping the ridges are sequentially connected to a mobile agricultural machine that travels on the ground surface, and a support section for supporting the irrigation tube and a ridge shaper for shaping the ridges are connected in sequence to a mobile agricultural machine that travels on the ground. A guide part for guiding the irrigation tube toward the upper surface of the shaped ridge is connected to the frame to form an integrated irrigation tube device, and this irrigation tube device is detachably connected to the mobile agricultural machine.

Function: Cultivate the field with the tiller and shape the ridges with the ridge shaper at the same time, and since there is a guide for the irrigation tube, you can ensure that the irrigation tube is placed in the correct position on the top of the shaped ridge. In addition, the irrigation tube can be prevented from twisting or loosening, and the support section and guide section that support the irrigation tube are connected to the frame and formed as an integrated irrigation tube device. Therefore, both the irrigation tube and the guide section can be easily attached to and removed from the mobile agricultural machine, and the preparation work for when it is necessary to install the irrigation tube and when it is not necessary can be simplified. .

Embodiment A first embodiment of this invention will be described based on FIGS. 1 to 4. An engine 3 is mounted on the front part of the chassis 2 of the mobile agricultural machine 1, a transmission case 4 is fixed approximately in the center of the chassis 2, and a handle 5 that can be turned in the front and rear directions is mounted on the upper part of the transmission case 4. installed. Further, a hitch 6 is fixed to the rear part of the chassis 2, and an intermediate tilling rotary 8 is connected to the hitch 6 by a king pin 7.

A transmission case 10 is fixed to approximately the center of the frame 9 of the intermediate tillage rotary 8, and a tillage case 10 is fixed to the lower end of the transmission case 10. A shaft 11 is provided, and a rotor 12, which is a tilling section that tills the field and brings the tilled soil to the center, is attached to the tilling shaft 11 by a pin (not shown). Further, a rear hitch 13 is fixed to the rear end of the frame 9, and a mounting stay 15 for a ridge shaper 14 is inserted into the rear hitch 13, and is tightened and fixed with a bolt (not shown).

Next, an irrigation tube device 16 is connected to the mounting stay 15. This irrigation tube device 16 first has a mounting stay 17, which is fitted into the mounting stay 15 so as to be slidable in the vertical direction, and is tightened and fixed at an arbitrary sliding position with a bolt 18. A frame 19 extending upward is fixed to the mounting stay 17, and a support shaft 20, which is a support portion, has an axis oriented horizontally in the left-right direction perpendicular to the traveling direction of the mobile agricultural machine 1 at the upper end of the frame 19. is fixed. An irrigation tube 21 wound in a roll is rotatably attached to the support shaft 20, and flat washers 22 are attached to both sides of the irrigation tube 21. In addition, the support shaft 2
A pin hole (not shown) is formed at the tip of 0,
A pin 23 for preventing the irrigation tube 21 and the flat washer 22 from moving in the axial direction of the support shaft 20 is removably inserted into this pin hole.

A substantially L-shaped subframe 24 that extends rearward and then bends downward is fixed to the substantially central portion of the frame 19 in the vertical direction.
The support shaft 2 is attached to the bent portion and the lower end of the support shaft 2, respectively.
A guide shaft 25 having an axis parallel to 0 is fixed. Collars 26, which are guide portions having approximately the same width as the irrigation tube 21, are rotatably attached to these guide shafts 25, and flat washers 27 are located on both sides of the collars 26.
is installed. A pin hole (not shown) is formed at the tip of the guide shaft 25, and the pin hole prevents the collar 26 and the flat washer 27 from moving in the axial direction of the guide shaft 25. A pin 28 is removably inserted therein.

In such a configuration, the mobile agricultural machine 1 is
When the rotor 12 moves in the direction, it first tills the field and brings the tilled soil to the center.
The ridges are shaped by a ridge shaper 14 located behind the honeycomb rotor 12.

Next, after the ridge shaping has started, the movement of the mobile agricultural machine 1 is temporarily stopped, the rolled irrigation tube 21 is pulled out rearward, and the irrigation tube 21 is moved above the collar 26 located above. At the same time, the irrigation tube 21 is guided through the lower part of the collar 26 to the upper surface of the ridge, and the end of the irrigation tube 21 is held at the end of the ridge, and the mobile agricultural machine 1 is again held.
Proceed in the direction of arrow a. Then, tilling by the honey rotor 12 and ridge shaping by the ridge shaper 14 are restarted, and furthermore, the irrigation tube 21 is moved in the direction of arrow b.
direction, and the irrigation tube 21 is placed on the upper surface of the shaped ridge. Therefore, cultivating the field, shaping the ridges, and laying the irrigation tubes 21 can be performed simultaneously in one work process. Further, the irrigation tube 21 is disposed at the center in the left-right direction of the intercultivation rotary 8, so that even when shaping a wide ridge, the irrigation tube 21 can be installed approximately at the center of the ridge. Furthermore, since the irrigation tube 21 is laid in a stretched state in the traveling direction of the mobile agricultural machine 1, it can be laid immediately without twisting or loosening.

Next, a second embodiment of this invention will be explained based on FIGS. 5 to 8. Incidentally, the same parts as those explained in FIGS. 1 to 4 are indicated by the same reference numerals, and the explanation thereof will be omitted. A multi-center support 29 extending rearward together with the mounting stay 17 of the irrigation tube device 16 is fastened to the mounting stay 15 with bolts (not shown). The multi-center support 29 is curved to avoid interference with the guide shaft 25 and extends to the rear position of the sub-frame 24, and the rear end of the multi-center support 29 is provided with a lateral direction of the intercultivation rotary 8. A multi-film support 30 is connected approximately at the center. A multi-film 31 wound into a roll is supported on this multi-film support 30. Further, a center guide roll 32 is connected to the multi-film support 30. Further, a pair of guide frames 33 extending rearward are attached to the upper ends of the left and right sides of the ridge shaper 14, and the rear ends of these guide frames 33 are attached to the sides of the multi-film 31 at the hem of the ridge. A treading wheel 34 and a soil covering disk 35 are attached to cover and fix the edge with soil. Note that the guide frame 33
The guide frame 33 is attached to the ridge shaper 14 so that the rear end portion of the guide frame 33 can freely rotate in the vertical direction.

In such a configuration, as the mobile agricultural machine 1 moves forward, plowing of the field by the rotor 12, shaping of the ridge by the ridge shaper 14, and laying of the irrigation tube 21 on the upper surface of the ridge are successively performed. Furthermore, by fixing both sides of the mulch film 31 to the hem of the ridge at the start of shaping the ridge, the rolled mulch film 31 is pulled out as the mobile agricultural machine 1 advances, and is attached to the ridge where the irrigation tube 21 is laid. Both sides of the multi-film 31 are covered and fixed with soil by a treading wheel 34 and a soil covering disk 35. Therefore, cultivating the field, shaping the ridges, laying the irrigation tubes 21, and covering the laid irrigation tubes 21 with the mulch film 31 from above can be performed in one work process.

Effects of the invention As mentioned above, this invention sequentially connects the tiller for cultivating the field and the ridge shaper for shaping the ridges to a mobile agricultural machine that runs on the ground, and connects the support part that supports the irrigation tube and the ridge shaper to the rear. A guide section for guiding the irrigation tube toward the upper surface of the shaped ridge is connected to a frame to form an integrated irrigation tube device, and the irrigation tube device is detachably attached to the mobile agricultural machine. Since they are connected, the cultivation section can till the field and the ridge shaper can shape the ridges at the same time, and since there is a guide section for the irrigation tube,
The irrigation tube can be reliably laid in a fixed position on the upper surface of the shaped ridge, and the irrigation tube can be prevented from twisting or loosening. Since it is formed as an integrated irrigation tube device connected to the frame, both the irrigation tube and the guide can be easily attached to and detached from the mobile agricultural machine.
This has the effect of simplifying the preparation work when it is necessary to install the irrigation tube and when it is not necessary.
