In the automatic liquid spraying vehicle, the front wheel 25 becomes the driving wheel when moving forward, and the rear wheel 3 becomes the driving wheel when moving backward.
The present invention is characterized by being equipped with a drive wheel switching mechanism 83 that can automatically switch so that 0 becomes the drive wheel.

(Function of the invention) The automatic liquid spraying vehicle of the invention can be used as a semi-automatic type.
It can also be used as a fully automatic system. When used as a semi-automatic type, liquid spraying is performed as shown in Figure 5. The effect in this case is as follows.

The scattering wheel 3 in Fig. 5 moves forward along the path B between the ridges A,
When pressed against the pusher 55 installed upright in the passageway B, it automatically retreats. Liquid is sprayed from the nozzle 40 of the spraying vehicle 3 during this forward and backward movement. Sprayer vehicle 3
When the spreader vehicle 3 has retreated to the starting end D of the passage B, the scattering vehicle 3 is manually moved to the adjacent passage B as indicated by the arrow d in FIG. The spraying vehicle 3 automatically moves forward and backward along this new path B in the same way as before, and liquid spraying is performed during this time. By repeating this process, each ridge A
The liquid is applied semi-automatically to the plants being grown.

When the automatic liquid spraying vehicle of the present invention is used as a fully automatic type, the liquid is sprayed using a running path 1 as shown in FIG. 1 and a cart 2 shown in FIG. 3 which moves laterally on the traveling path 1 as shown in FIG. The effect in this case is as follows.

The scattering vehicle 3 that has descended from the cart 2 on the running path 1 to the path B between the ridges A automatically moves forward along the same path B, and when it presses against the pusher 55 erected in the path B, it automatically moves forward. to retreat. When moving forward or backward, the spreading vehicle 3
Liquid is sprayed from the nozzle 40 of. When the scattering vehicle 3 retreats to the starting end D of the passage B, it automatically rides on the cart 2 and stops. Liquid is sprayed from the nozzle 40 of the spraying vehicle 3 onto the plants cultivated in the ridges A at desired times during the forward movement and during the backward movement.

When the spreading vehicle 3 stops on the trolley 2, the trolley 2 automatically moves laterally on the running path 1 and automatically stops in front of the adjacent passage B. At this stop, the spreading vehicle 3 automatically descends to aisle B, and as before,
moves forward and backward, and liquid is sprayed during that time. By repeating this process, the liquid is automatically sprayed onto the plants grown in each row A.

(Embodiment) An embodiment of the automatic liquid spraying vehicle of the present invention will be described based on FIG. 4.

Reference numeral 81 in FIG. 4 is a spreading wheel drive mechanism, which moves the spreading wheel 3 forward and backward. This scattering wheel drive mechanism 81 includes a motor M, gears G1 to G6,
It consists of a chain 19, a forward switch S1, a back switch 28, etc.

A motor M is attached to the spreading wheel 3.
This motor M is a forward and reverse rotation motor, and the vertical frame 22
When the forward switch S1 attached to the gear is turned on, it rotates forward, gear G1 rotates, gear G2 connected to the gear G1 by a chain 19 rotates, and the shaft 20 rotates. The gears G3 and G4 and the rotary wheel 21 are arranged to rotate. Along with these rotations, gear G5, which is connected to gear G3 by a chain 23, also rotates.
, the shaft 24 rotates, the front wheel 25 rotates, and the spreading wheel 3 moves forward to the left in FIG. 4.
In this case, the chain 25 attached to gears G4 and G6
is set to idle.

Reference numeral 83 in FIG. 4 is a drive wheel switching mechanism, which switches the front wheels 25 to become the drive wheels when moving forward, and the rear wheels 30 to become the drive wheels when moving backward. This drive wheel switching mechanism 83 includes a back switch 28, a forward/reverse rotary motor M, and a gear G1.
~G6, chain 26, chain 23, etc. This switching by the drive wheel switching mechanism 83 is performed as follows.

When the back switch 28 attached to the front horizontal frame 27 is turned on, the motor M rotates in the opposite direction, causing the gears G1, G2, shaft 20, and gear G4 to rotate in the opposite direction to the previous rotation, and are connected to the gear G4 by the chain 26. The gear G6 also rotates in the opposite direction, and the shaft 29 and rear wheels 30 further rotate in the opposite direction to the driving direction of the front wheels 25, causing the spreading wheel 3 to move backward in the right direction in FIG. In this case, gears G3 and G5
The chain 23 that is hung on the shaft is designed to spin idly.

Reference numeral 82 in FIG. 4 is a liquid spraying mechanism, which is used to spray liquid when the spraying vehicle 3 moves forward or backward. The liquid dispersion mechanism 82 is the hose 3 shown in FIG.
3, winding drum 31, on-off valve 37, nozzle 40,
It is composed of an opening/closing lever 41, an interlocking lever 43, and the like.

Reference numeral 31 in FIG. 4 is a hose winding drum, which connects the rotating wheel 21 attached to the shaft 20 and the rotating wheel 32 of the drum 31 with a belt 33.
When the spreading wheel 3 moves forward, the hose 33 rotates in the direction in which it is paid out, and when it moves backward, it rotates in the direction in which the hose 33 is wound up.

One end 34 of the hose 33 is connected to a liquid tank (not shown), and the other end 35 is pulled out from inside the rotating shaft of the winding drum 31 to prevent the hose from tangling even when the drum rotates. There is.
Furthermore, the tip 36 of the hose 33 is connected to a bifurcated connector 38 via an on-off valve 37, a pipe 39 is connected to the bifurcated connector 38, and a nozzle 40 is attached to the end of this pipe 39 to supply liquid from the liquid tank. The liquid to be sprayed is sprayed from the same nozzle 40.

The spray from the nozzle 40 is sprayed when the spreading vehicle 3 moves forward.
This is done either or both times when reversing. What is shown in the figure is that when the spreading wheel 3 moves forward, the on-off valve 37 to which the hose 33 is connected closes and no liquid is sprayed from the nozzle 40, and only when the spreading wheel 3 moves backward, the on-off valve 37 opens and the liquid flows out from the nozzle 40. It is designed to be sprayed.

The on-off valve 37 is opened when the on-off lever 41 attached to the tip of the scattering wheel 3 is pushed in the direction of the arrow y, and closed when pushed in the opposite direction. Also the fourth
In the figure, the opening/closing lever 41 is connected to an interlocking lever 43 attached to the rear end of the scattering wheel 3 by a coupling 42, and when the interlocking lever 43 is pushed in the direction of the arrow x, the opening/closing lever 41 returns to the direction of the arrow x. Then, the on-off valve 37 is closed.

Reference numeral 44 in FIG. 4 is a winding adjustment body that adjusts the amount of winding of the hose onto the winding drum 31. This connects the shaft 46 to which the two arms 45 are attached to the vertical frames 22 and 4.
A rotary roller 48 is rotatably mounted between the arms 45, and a hose support rod 49 is mounted below the rotary roller 48.

A connecting rod 50 is attached to the arm 45, and its tip is attached to a support arm 52 rotatably attached to a vertical rod 51 so that the connecting rod 50 is always pulled to the right in the drawing. As a result, the belt 70 is pressed to the right in the drawing by the roller 54 attached to the lower end of the support arm 52, and tension is applied to the belt 70. When the spreading wheel 3 moves forward or backward in this state, the winding The drum 31 is configured to rotate forward or backward.

When the spreading wheel 3 moves backward and the hose 33 is wound around the winding drum 31, the diameter of the hose 33 wound around the drum 31 becomes larger and the hose 33 becomes larger.
When the winding speed of the hose 3 increases, the roller 48
A tensile force of 3 is applied to lift the roller 48 upward. As a result, the lower part of the arm 45 rotates upward about the shaft 46, the coupling tool 50 is pressed forward of the spreading wheel 3, the pressure on the belt 70 by the roller 54 is released, and the belt 70 becomes slack and rotates. The rotational force of the wheel 21 is no longer transmitted to the winding drum 31, and the hose 33 is no longer transmitted to the winding drum 31.
winding is automatically stopped.

When the winding is stopped, the hose 33 becomes slack and the roller 48 cannot be lifted up, so the connector 50 is pulled by the spring 53 and the roller 54 is pulled up.
presses the belt 70 again. As a result, the winding drum 31 rotates again to resume winding the hose 33, and the winding amount of the hose 33 is automatically adjusted.

1 in FIG. 1 is a running route. This means that when using the automatic liquid spraying vehicle of this invention as a fully automatic type,
This is for moving the trolley 2 laterally. This traveling route 1 consists of two rails 4 and 5 as shown in Figure 2.
are connected by a connector 6.

80 in FIG. 3 is a truck drive mechanism. This is also for laterally moving the truck 2 when the automatic liquid spraying vehicle of the present invention is used as a fully automatic type. This trolley drive mechanism 80 automatically moves the trolley 2 horizontally on the traveling furnace 1 when the scattering vehicle 3 runs onto the trolley 2, and automatically moves the trolley 2 when the trolley 2 moves to a predetermined position. It is intended to stop the operation. This truck drive mechanism 80 includes the wheels 10 in FIG. 3, the power source 12, a truck start switch and a truck stop switch (not shown) attached to the truck 2, and a pusher that these switches press to turn ON and OFF. It is composed of children (not shown), etc.

As shown in FIG. 3, the truck 2 has shafts 8 and 9 attached to the frame 7, and rails 4 and 5 shown in FIG.
A wheel 10 is attached to run on the top of the wheel. These wheels 10 are recessed at their widthwise central portions 11 to prevent them from accidentally coming off the rails 4 and 5. These wheels 10 are rotated by a power source 12 via shafts 8,9. Power source 12 is attached to frame 7.

Guide paths 13 and 14 for the spreading vehicle 3 to ride on are formed in the frame 7 of the truck 2, and auxiliary paths 15 and 16 that widen toward the tip are attached to the respective tips. The auxiliary passages 15 and 16 are attached by hinges 17 and 18, respectively, so that they can be rotated 90 degrees in the direction of the arrow (upward) from the position shown in FIG. 3 and stand vertically. Moreover, these auxiliary roads 15 and 16 are the guide path 1.
When the spreading vehicle 3 runs on the guide roads 13 and 14, it automatically stands up in the direction of the arrow (upward) by an appropriate means, and the spreading vehicle 3 runs on the guide roads 13 and 14.
Make sure you don't fall off from 4.

The operation of the automatic liquid spraying vehicle of the present invention constructed as described above, when used in a fully automatic manner in combination with the traveling path 1 and the trolley 2 as shown in FIG. 1, will be described in detail below.

The trolley 2 carrying the scattering vehicle 3 is moved on the running path 1 to move it to any one of the many paths B.
stop before. At this time, the interlocking lever 43 attached to the rear end of the scattering vehicle 3 presses against a pusher (not shown) provided on the travel path 1 and presses the arrow
As a result, the opening/closing lever 41, which is interlocked with the same lever 43, is pushed in the direction of the arrow x, closing the opening/closing valve 37, and the spraying of liquid from the nozzle 40 is stopped.

In this state, when the forward switch S1 attached to the rear of the spreading vehicle 3 is manually turned on, the front wheels 25 are driven by the motor, and the spreading vehicle 3 moves forward, descends from the auxiliary roads 15 and 16 of the trolley 2, and goes into the passageway. B
run.

When the spreading wheel 3 moves forward and the back switch 28 attached to the front side presses against the pusher 55 installed at the end of the passage B, the spreading wheel 3 moves forward.
The motor M rotates in the opposite direction to drive the rear wheels 30, and the spreading wheel 3 moves backward.

When the back switch 28 presses against the pusher 55, the opening/closing lever 41, which is provided in front of the switch 28, also presses against the pusher 55 and presses the arrow y.
As it rotates to the side, the on-off valve 37 opens, and as the spray wheel 3 moves backward, liquid is sprayed from the nozzle 40. In this case, when motor M rotates, motor M
The arm 56 attached to the
Since the rotating ring 57 attached to the tip of the motor presses down the holder 58, the support plate 59 to which the holder 58 is connected rotates up and down each time the motor M rotates once, causing the nozzle 40 to move up and down. It is in a swinging state, and the liquid is sprayed from top to bottom of the vegetables grown in row A.

In this way, if the liquid is not sprayed when the spraying vehicle 3 moves forward, but only when it retreats, the spraying vehicle 3
I've never had a case where it leaked or got dirty when I touched it when reversing. This liquid spraying may be performed not when reversing, but when the vehicle is moving forward, or may be performed both when moving forward and reversing.

The spreading vehicle 3 moves backward while dispersing the liquid and runs onto the guide paths 13 and 14 from the auxiliary paths 15 and 16 of the truck 2, and the stop switch S2 attached to the rear end of the spreading vehicle 3 is installed on the truck 2. When it is pressed against a pusher (not shown), it stops.

When the spreading vehicle 3 runs onto the guide paths 13 and 14,
The auxiliary passages 15 and 16 are connected to the hinges 17 and 16 by appropriate means.
The scattering wheel 3 is raised using the support shaft 18 to prevent it from sliding off the guide paths 13 and 14.

Also, at this time, the interlocking lever 43 attached to the rear end of the spreading vehicle 3 presses against a pusher (not shown) attached to the trolley 2 and rotates in the direction of the arrow x, thereby causing the interlocking The opening/closing lever 41 interlocked with the lever 43 rotates in the direction of the arrow x, the opening/closing valve 37 is closed, and liquid spraying from the nozzle 40 is stopped.

Furthermore, at this time, a trolley start switch (not shown) attached to the trolley 2 is activated to start the spreading vehicle 3.
is pressed and turned on, and motor 1 of trolley 2
2 is driven and the trolley 2 moves on the running path 1, and when the trolley 2 reaches the position of the adjacent passage B, a trolley stop switch (not shown) attached to the trolley 2 is activated.
It is stopped by pressing against a stop pusher (not shown) provided on the running path 1.

When the trolley 2 stops, the forward switch S of the spreading vehicle 3
1 is pressed against a pusher (not shown) provided on the traveling path 1 and turned on, and the front wheels 25 are driven and start moving forward as in the previous time. At this time, the auxiliary roads 15 and 16 of the trolley 2 automatically descend using the hinges 17 and 18 as support shafts, and the spreading vehicle 3 moves to the lowered auxiliary roads 15 and 16.
Go through it, go down to passage B, and move forward along the same passage. Thereafter, repeating the previous process of backing up while spraying the liquid - riding on the trolley 2 and stopping - stopping the trolley 2 from moving to the next passage B - moving the spraying vehicle 3 forward to the passage B, the vegetables in all the rows A are covered. Liquid is sprayed sequentially.

(Effect of the invention) As described above, the automatic liquid spraying vehicle of the present invention has the front wheel 25 when moving forward due to the section drive wheel switching mechanism 83.
The rear wheels 30 become the driving wheels, and when reversing, the rear wheels 30 are switched to become the driving wheels. Therefore, the spraying vehicle 3 does not slip even when driving on a wet path B or in a puddle, or when driving sideways. It moves straight forward and backward along path B with almost no wobbling.

The automatic liquid spraying vehicle of this invention can be used as a semi-automatic type as well.
Since it can also be used as a fully automatic type, it can be used depending on the purpose and place of use. Particularly when used as a fully automatic system, the loading and unloading of the spreading vehicle 3 on and off the trolley 2, the lateral movement of the spreading vehicle 3 due to the movement of the trolley 2, etc. are all performed automatically, so if the start switch is turned on, then does not require any human intervention. Therefore, unattended automatic liquid spraying becomes possible, and work efficiency is significantly improved. Furthermore, since manpower is no longer required, the manpower can be used more effectively for other tasks.
