DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.
[0012]
FIG. 1 schematically shows a state of control work performed using a spraying apparatus according to the present embodiment in an orchard or the like provided on a vast steep slope.
[0013]
A rail 1 as a support guide member is provided in the orchard in the steep slope, which is a spraying area, from the mountain skirt where the vehicle can enter upward. The rail 1 is a single rail, and is laid in parallel in a necessary number by folding back in parallel at a predetermined interval in advance on the steep slope in correspondence with a spray width by a spray nozzle 2 described later. Each rail 1 is laid at an appropriate height from the ground by rail struts 3 of an appropriate length so that the sprayed material (chemical solution) can be appropriately applied to each tree of the orchard. Each rail column 3 is erected with an appropriate interval between adjacent ones, and firmly supports the rail 1 on the steep ground.
[0014]
For example, a chemical supply vehicle CV having a large-capacity chemical solution tank 4 is stopped as a spray supply source near the end of the rail 1 on the mountain skirt side. The chemical solution in the chemical solution tank 4 is pumped toward the spray nozzle 2 by a chemical solution pump 5 as a sprayed material delivery device.
[0015]
On the rail 1, a self-propelled device 6 that can reciprocate back and forth is provided as a moving device. Although not shown in detail, for example, the self-propelled device 6 is driven by a machine body 7 having an upper roller and a lower pinion arranged so as to sandwich the rail 1 from above and below, respectively. As a source, for example, an internal combustion engine is mounted, and the configuration is known per se.
[0016]
The upper roller of the machine body 7 is in pressure contact with the flat upper surface of the rail 1. On the other hand, a rack 8 that meshes with each lower pinion of the machine body 7 is fixed to the lower surface of the rail 1 along its length direction (see FIG. 3). Each upper roller and each lower pinion is formed with flange portions for preventing the rail 1 and the rack 8 from being detached at both left and right end portions thereof. The aircraft 7 freely travels forward and backward along the rail 1 at a moderate speed along the rail 1 by the engine driving the lower pinion via a mission device (not shown).
[0017]
In FIG. 1, the self-propelled device 6 is a passenger-type device including a seat 9 and a control device 10. However, the present invention is not limited to this, and an unmanned self-propelled device may be adopted. Good.
[0018]
A carriage 12 is connected to the rear of the self-propelled device 6 via a coupler 11. The carriage 12 constitutes a moving device together with the self-propelled device 6.
[0019]
FIGS. 2 to 4 are a perspective view, a side view, and a plan view, respectively, of the cart 12 part, and FIG. 5 is a view taken along the arrow V in FIG.
[0020]
As shown in FIG. 3, the cart 12 has two pairs of an upper roller 13 and a lower pinion 14 arranged so as to sandwich the rail 1 from above and below, and the self-propelled device 6 At the same time, it moves back and forth on the rail 1. Each upper roller 13 and each lower pinion 14 is formed with flange portions 15 at the left and right ends thereof to prevent detachment from the rail 1 or the rack 8.
[0021]
On the carriage 12, the spray nozzle 2 is mounted at the rear thereof, and a reel device 16 is disposed at the front thereof. The reel device 16 unwinds and winds a hose 17 as a flexible communication member that allows the spray nozzle 2 and the chemical solution tank 4 to communicate with each other according to the moving speed of the carriage 12.
[0022]
For example, the carriage 12 spreads the chemical solution in the chemical solution tank 4 placed on the foot side of the mountain from the spray nozzle 2 over a wide range while going up on the steep slope. Further, when the carriage 12 reaches the end of the rail 1, the spraying from the spray nozzle 2 is stopped (or the spraying is continued), and the hoist 17 is wound up by the reel device 16, and the cart is moved. 12 goes backwards and goes down the steep slope and returns to the starting point. This completes the work of one stroke.
[0023]
In the example shown in the drawing, the spray nozzles 2 are provided in a large number in a radially upward manner with appropriate intervals between adjacent ones along the upwardly curved nozzle tube 18 as in the case of a ground traveling speed sprayer. ing. The spray nozzle 2 is located at an air outlet 20 for blowing air by a blower 19 mounted on the carriage 12. Then, the blower 19 spreads and spreads the chemical solution sprayed from the spray nozzle 2 on the left and right sides and upward of the radial blow, and diffuses and spreads the left and right sides of the carriage 12.
[0024]
The blower 19 is driven by, for example, an internal combustion engine 21 as a drive source mounted on the carriage 12. An engine cover 22 is provided above the engine 21.
[0025]
It is preferable that the entire spraying device 50 configured as described above is made to be variable on the carriage 12 with an appropriate turntable mechanism 51 and the spraying direction is variable.
[0026]
On the other hand, the reel device 16 includes a drum-shaped reel body 23 and a frame 25 that supports a rotating shaft 24 of the reel body 23. The reel body 23 is arranged so that the rotation shaft 24 extends to the left and right sides in the traveling direction of the carriage 12. The end portion of the hose 17 on the downstream side of liquid passage is inserted into the rotation shaft 24 of the reel body 23 and communicates with a rotation joint 26 provided at one end portion thereof (see FIG. 4). . The rotary joint 26 communicates with the nozzle pipe 18 through an appropriate liquid passage pipe 27. The liquid passage 27 is provided with an appropriate opening / closing cock (not shown) that can be remotely operated.
[0027]
The reel device 16 rotates when the carriage 12 moves forward along the rail 1 and climbs the steep slope, unwinds the hose 17 according to the moving speed of the carriage 12, and moves the carriage 12. Is driven along the rail 1 and descends the steep slope, and the hose 17 is wound up according to the moving speed of the carriage 12.
[0028]
More specifically, the rotation shaft 24 of the reel body 23 is extended to the left of the front-side lower pinion 14 of the carriage 12 via sprockets 29 and 30 and a chain 31. 28 for driving. The drive system of the reel device 16 is provided with a one-way clutch 32 that transmits the rotation of the front lower pinion 14 of the carriage 12 to the reel body 23 only when the hose 17 is wound up. (See FIG. 4 and FIG. 5). For this reason, when the carriage 12 rises along the rail 1, the rotation of the lower pinion 14 of the carriage 12 is not transmitted to the reel body 23, and the reel body 23 rotates freely. Here, the end of the hose 17 on the upstream side of the liquid flow is connected and fixed to the discharge port 5a of the chemical pump 5 as shown in FIG. The hose 17 is fed out according to the forward speed.
[0029]
The drive system of the reel device 16 is also provided with an appropriate torque limiter device 33 having a configuration known per se (see FIG. 5). The torque limiter device 33 acts to synchronize the traveling speed of the carriage 12 and the winding speed of the hose 17 by the reel body 23 when the carriage 12 moves backward and descends the steep slope. For this reason, the hose 17 can be reliably wound around the reel body 23 without loosening.
[0030]
Further, the reel device 16 has a hose aligning and winding mechanism for arranging the hoses 17 in an orderly manner along the winding width of the reel body 23. The hose alignment take-up mechanism includes a rotatable traverse shaft 34 installed in parallel to the rotating shaft 24 behind the reel body 23, and a traverse shaft 34 provided on the traverse shaft 34. A moving block 35 that reciprocates in the axial direction along with the movement, and a fixed guide bar 36 that engages with the moving block 35 and guides the moving block 35 so as to be slidable to the left and right. The hose 17 is inserted through the moving block 35 with appropriate play.
[0031]
The traverse shaft 34 is drivingly connected to the rotation shaft 24 of the reel body 23 via sprockets 37 and 38 and a chain 39, and the traveling speed of the carriage 12 is increased by the action of the torque limiter device 33. The moving block 35 is driven to reciprocate left and right in accordance with the hose winding speed of the reel body 23 to be synchronized. For this reason, when the reel body 23 winds the hose 17, the hose 17 is arranged in an orderly manner on the circumferential surface of the reel body 23 without a gap.
[0032]
Further, the reel device 16 has a hose localization guide for making the winding position and unwinding position of the hose 17 in the left-right direction of the hose 17 constant by the reel device 16 on the upstream side of the passage of the hose 17 from the moving block 35. As a member, a pair of left and right guide rollers 40, 40 fixed to the frame 25 is provided. The pair of left and right guide rollers 40, 40 hold the hose 17 therebetween, and draw out and collect the hose 17 at a predetermined position regardless of the left and right reciprocating movement of the moving block 35. For this reason, there is no problem that the hose 17 meanders.
[0033]
When the carriage 12 moves forward and climbs the steeply inclined surface, the hose 17 fed out at a predetermined position by the pair of left and right guide rollers 40, 40 is preliminarily provided along the rail 1, for example, along the right side of the guide roller 40. , 40 is automatically hooked by a U-shaped hooking member 41 provided at a position immediately below the head. The latching member 41 is fixed to each rail column 3 that supports the rail 1 at a predetermined interval, and prevents the hose 17 that has been drawn out from drooping unnecessarily.
[0034]
According to the spraying device according to the present embodiment configured and acting as described above, since no chemical tank is mounted on the carriage 12, the total weight of the carriage 12 is reduced and it is safe and is placed on the ground. Since the chemical solution can be continuously sprayed from the large-capacity chemical solution tank 4 for a long time, the working efficiency is good.
[0035]
In addition, since a unique drive source is not required for winding the hose, the configuration is intensive, light weight and inexpensive.
[0036]
Furthermore, since the unwinding and winding speeds of the hose 17 are synchronized with the moving speeds of the self-propelled device and the carriage, there is no problem that the hose 17 interferes with the spraying operation. Furthermore, since the drawn-out hose 17 is hooked on the retaining member 41, there is no inconvenience that the hose 17 hangs unnecessarily.
[0037]

According to the present invention, a spraying operation can be performed safely and efficiently.
[0038]
According to the third aspect of the present invention, the flexible communication member is neatly wound on the reel body.
[0039]
According to the fourth aspect of the present invention, there is no problem that the communicating member meanders when the flexible communicating member is wound or unwound.
[0040]
According to the fifth aspect of the present invention, there is no problem that the unwound flexible communication member hangs unnecessarily.
[0041]
