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.

Next, depending on the crop cultivation system, crops may be planted eccentrically from the center of the ridge, and in such cases, irrigation tubes should also be laid eccentrically from the center of the ridge. There must be. In addition, some crops are grown by making the top of the ridge a slope and planting the crop above the slope while extending the vines and stems below the slope. It must be installed above the slope at the base.

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.

Measures to solve the problem For these reasons, as seen in Japanese Utility Model Application Publication No. 48-9539, a sheet covering machine was connected to the rear of the tilling machine, and the irrigation hose was wound and stored. There is a system in which a reel is attached, and along with work such as ridge building, irrigation hose installation and sheet covering are performed at the same time.

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 the irrigation tube device is detachably connected to the mobile agricultural machine,
The irrigation tube is provided so as to be movable and fixed at any position on the support part along the left-right direction perpendicular to the traveling direction of the mobile agricultural machine, and the guide part is arranged along the left-right direction perpendicular to the traveling direction of the mobile agricultural machine. It can be moved freely and fixed at any position.

Function: Cultivate the field with the tiller and shape the ridges with the ridge shaper at the same time.Furthermore, since there is a guide for the irrigation tube, the irrigation tube can be reliably laid in the correct position on the top of the shaped ridge. Moreover, it is possible to prevent twisting and loosening of the irrigation tube. In particular, by moving the irrigation tube and the guide part in the left and right direction and adjusting the position, the installation position of the irrigation tube can be adjusted to the center of the ridge. It is possible to change the position eccentrically from the center of the ridge or the ridge.
Since the support part and the guide part that support the irrigation tube are connected to the frame and formed as an integrated irrigation tube device, both the irrigation tube and the guide part can be easily attached to and removed from the mobile agricultural machine. , it is possible to simplify the preparation work when it is necessary to install the irrigation tube and when it is not necessary.

Embodiment An embodiment of this invention will be described based on the drawings. 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 bolts (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 into a roll is attached to the support shaft 20 so as to be rotatable and movable along the axial direction of the support shaft 20. Furthermore, flat washers 22 are installed on both sides of the irrigation tube 21.
is installed. A plurality of pin holes 23 are formed in the support shaft 20 at intervals slightly wider than the horizontal width of the irrigation tube 21, and pins 24 detachably inserted into these pin holes 23 allow The irrigation tube 21 and the flat washer 22 are prevented from moving in the axial direction of the support shaft 20.

A substantially L-shaped subframe 25 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 5, respectively.
A guide shaft 26 having an axis parallel to 0 is fixed. A collar 27, which is a guide portion having a width substantially the same as the width of the irrigation tube 21, is attached to these guide shafts 26 so as to be rotatable and movable along the axial direction of the guide shafts 26, and further,
Flat washers 28 are attached to both sides of the collar 27. A plurality of pin holes 29 are formed in the guide shaft 26 at intervals slightly wider than the width dimension of the collar 27, and pins 30 are removably inserted into these pin holes 29.
This prevents the collar 27 and the flat washer 28 from moving in the axial direction of the support shaft 20.

Next, a multi-center support 31 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). Note that the multi-center support 31 is curved to avoid interference with the guide shaft 26 and attached to the subframe 2.
A multi-film support 32 is connected to the rear end of the multi-center support 31 at approximately the center of the intercultivation rotary 8 in the left-right direction. A multi-film 33 wound into a roll is supported on this multi-film support 32. Furthermore, a center guide roll 34 is connected to the multi-film support 32 . Further, a pair of guide frames 35 extending rearward are attached to the upper end portions of the left and right sides of the ridge shaper 14, and the rear end portions of these guide frames 35 are attached to the side of the multi-film 33 at the hem of the ridge. A treading wheel 36 and a soil covering disk 37 are attached to cover and fix the edge with soil. The guide frame 35 is attached to the ridge shaper 14 so that the rear end of the guide frame 35 can freely rotate in the vertical direction.

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, immediately after the ridge shaping is 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 placed above the collar 27 located above. The irrigation tube 21 is passed through and guided to the upper surface of the ridge through the lower part of the collar 27 located below, and the end of the irrigation tube 21 is held at the end of the ridge. Furthermore, the multi-film 33 is pulled out rearward and both sides of the multi-film 33 are fixed to the hem of the ridge. When the mobile agricultural machine 1 is moved again in the direction of the arrow a from this state, tillage by the rotor 12 and ridge shaping by the ridge shaper 14 are resumed, and furthermore, the irrigation tube 21
is pulled out while rotating in the direction of arrow b around the axis of the support shaft 20, and laid on the upper surface of the ridge. On the other hand, as the mobile agricultural machine 1 advances, the roll-shaped mulch film 33 is pulled out and covers the ridge where the irrigation tube 21 is laid, and both sides of the mulch film 33 are covered with soil by the tread wheels 36 and the soil covering disk 37. . Therefore, cultivating the field, shaping the ridges, laying the irrigation tubes 21 on the upper surface of the ridges, and covering the laid irrigation tubes 21 with the mulch film 33 from above can be performed in one work process. Moreover, since the irrigation tube 21 is laid under tension in the direction of movement of the mobile agricultural machine 1, it is laid immediately without twisting or loosening.

Here, as shown in FIG.
When the collar 27 is placed at the center in the left-right direction of the intercultivation rotary 8, the irrigation tube 21 is installed at the center of the shaped ridge. Next, the irrigation tube 21 is moved along the axial direction of the support shaft 20, and the collar 27 is moved along the axial direction of the guide shaft 26, and as shown in FIG. Move it to an eccentric position. When the mobile agricultural machine 1 is driven from this state to shape the ridge and install the irrigation tube 21, the irrigation tube 21 is installed at a position eccentric from the center of the ridge. The irrigation tube 21 is prevented from moving in the left-right direction by pins 24 located on both sides, and the collar 27 is prevented from moving in the left-right direction by pins 30 located on both sides. Also, the fourth
As shown in the figure, when the irrigation tube 21 and the collar 27 are moved to a position further eccentric from the center of the intercultivation rotary 8, the irrigation tube 2
1 is laid at a position further eccentric from the center of the ridge. Therefore, even when the crops are planted in the center of the ridge or in a position eccentric from the center of the ridge, the irrigation tube 21 can be reliably installed near the roots of the crops.

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. the irrigation tube is movable on the supporting part and can be fixed at any position along the left and right directions perpendicular to the traveling direction of the mobile agricultural machine, and the guide part is provided in the left and right directions perpendicular to the traveling direction of the mobile agricultural machine. Since it is movable along the direction and can be fixed at any position, the tilling section can till the field and the ridge shaper can shape the ridges at the same time.Furthermore, since there is a guide section for the irrigation tube, the ridges can be shaped easily. The irrigation tube can be reliably laid in a fixed position on the upper surface, and the irrigation tube can be prevented from twisting or loosening, and in particular, the irrigation tube and the guide can be moved in the left-right direction to adjust the position. By doing so, the installation position of the irrigation tube can be changed to the center of the ridge or a position eccentric from the center of the ridge, and the support part and guide part that support the irrigation tube can be connected to the frame and integrated. Since the irrigation tube device is designed as an irrigation tube device, both the irrigation tube and guide can be easily attached to and removed from the mobile agricultural machine, making it possible to perform preparatory work when installing the irrigation tube and when not. This has effects such as being able to simplify the process.
