DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a set dynamic sprayer which is integrally provided with a power sprayer, a drive source thereof, and wheels for traveling, and is suitable for spraying agricultural chemicals.

[0002]

2. Description of the Related Art Conventionally, a control sprayer called a set dynamic spray used in a field or the like for spraying agrochemicals includes a power sprayer for spraying agrochemicals, and a prime mover for driving the power sprayer. In addition, a spray hose connected to a power sprayer and a hose winder for winding and storing the spray hose are compactly and balancedly arranged on a frame. Recently, there has been developed one in which wheels for traveling, such as casters, are arranged on a frame to facilitate transportation in a field when spraying pesticides. A truck is generally used to transport such a set dynamic jet to or from a field.

[0003]

However, since such a set dynamic jet has a considerable weight,
2. Description of the Related Art Conventionally, when loading or unloading on a truck bed, it has been necessary to work by a plurality of persons or to use a large cargo handling machine such as a forklift. However,
Few ordinary farmers have large cargo handling machines, and the latter method is not practical. Therefore, although the former method must be used, there are many cases where inconsistencies arise in the unloading work by humans in conjunction with the declining agricultural population and the aging tendency of farmers.

[0004] In view of such a problem, it has been considered that a prime mover of a power sprayer can be connected to a caster so as to be able to run on its own using the power of the prime mover. With this configuration, the set moving jet is allowed to run on the bridge bridged between the truck bed and the ground, so that the individual can unload the truck bed.

However, such a configuration requires a complicated deceleration mechanism and clutch, a brake mechanism for stopping traveling, a safety device, and the like. Or increase in weight. In particular, an increase in weight is not preferable in view of manual movement in a field or the like. Further, since the self-propelled vehicle requires a clutch operation, a brake operation, a direction control operation, and the like, the operation is difficult, and there is a problem that it is difficult for a user, particularly an elderly person, to cope with the operation. In addition, there is also a disadvantage that an operational error is likely to be caused, so that the security tends to be lacking.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and to provide a set moving jet capable of safely loading and unloading by an individual with a simple structure and operation. By equipping the frame with an electric winding means, the leading end of a towing string member such as a wire is hooked on a fixed end set on a truck bed or the like, and the towing string member is wound up when loading on the bed. In this way, the bridge can be climbed, and when it is lowered to the ground, the wire is paid out so that the bridge can be lowered by its own weight.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A set dynamic jet according to the present invention comprises a power atomizer for spraying a liquid such as an agricultural chemical, a drive source for driving the power atomizer, and a power source for the power atomizer. A connected spray hose and a traveling wheel are integrally provided on a frame, and electric winding means capable of winding or feeding out a towing string member is provided on the frame. An operating means for selectively switching the winding means to at least three states of a stop state, a winding operation state, and a feeding operation state is provided.

In such a case, for example, the leading end of the traction string member is hung on the bed of a truck, and the winding means is set in a winding operation state to wind up the traction string member. The bridge built between the ground and the ground can be climbed on its own and loaded onto a cargo bed. In addition, when the bridge is lowered to the ground, the bridge can be slowly lowered by utilizing its own weight by pulling out the traction string member in the feeding operation state. Thus, the unloading operation can be performed by an individual.

In addition, since this unloading operation is basically performed only by switching the operation means, it is very simple and hardly causes an operation error. In addition, even if an operation error occurs, the set dynamic jet is always connected by the towing string member, so that the safety is high. Furthermore, since the winding means and the like may be mounted by additional processing without changing the configuration of the existing set dynamic jet, the realization is extremely easy, and there is no significant increase in cost and weight. The fact that the cost does not increase is a great advantage for small and medium-sized farmers, and the fact that it does not increase the weight is a great effect when hand-moving in a field or the like. Furthermore, since the winding means is electrically driven, it has an additional effect of being quiet.

[0010] For example, in order to easily fix the truck to the carrier using the winding means during transportation, it is necessary to provide a fixing means connectable to a first fixed end set on the carrier or the like. A frame is provided, the fixing means and the first fixed end are connected to each other, and the tip of the traction string member is hung on a second fixed end set on a carrier or the like, and the traction string member is wound. By winding and stretching by taking means,
It is preferable that the traction force acting on the frame via the traction cord member and the anti-traction force acting on the frame via the fixing means connected to the first fixing end be antagonized and fixed.

[0011] In order to suitably perform such fixing, it is desirable that the fixing means and the winding means are respectively provided at opposite ends along the running direction of the frame. As an easy-to-implement embodiment of the fixing means, there can be cited one in which the fixing means is a hook and is configured to be connectable to the first fixed end via a fixing cord member.

In order to facilitate the operation of the winding means, the operating means is an operation switch capable of connecting and disconnecting the winding means and its power source, and this operation switch is provided on the frame. It is preferable to dispose it on the operating handle. In order to prevent the winding means from being stopped simply by releasing the hand from the operation switch, to prevent the operator from forgetting to turn off the operation switch, and to increase the safety in the event of an erroneous operation, the operation switch must be operated only while receiving the operating force. It is desirable that the winding means and its power source be energized to be activated.

When the power source of the winding means is a battery, the battery can be automatically charged by charging the battery with a drive source for driving a power sprayer. It is preferable to keep it.

[0014]

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a set dynamic injection 1 according to the present embodiment.
00 is shown. The set dynamic jet 100 includes a power sprayer 1 for spraying a liquid such as an agricultural chemical, an engine 2 serving as a drive source for driving the power sprayer 1, and a sprayer connected to the power sprayer 1. Hose 3 and this spray hose 3
And a caster 51, 52, which is a running wheel, are integrally provided on the frame 6, and are suitably used for spraying agricultural chemicals and the like.

To describe each part in detail, the frame 6 is made of a pipe material, an angle material or the like, and an operation handle 61 is provided integrally with the frame 6 at one end side in the running direction. The operation handle 61 is used at the time of manual pushing movement in a field or the like. The power atomizer performs a pumping operation for increasing the pressure of the liquid and ejecting the liquid, and is driven by the engine 2 in this embodiment.

The spray hose 3 is for spraying the pesticide pumped from the power sprayer from the tip. The hose winder 4 is a drum type for winding the spray hose 3. The casters 51 and 52 are
Are provided at the four corners, and a pair 51 located at one end side along the traveling direction of the frame 6 and below the operation handle 61 is a free type that is rotatable in a horizontal plane. The other pair 52 located on the end side is a fixed type. With such a configuration, it is configured such that the direction can be changed at the time of manual pushing movement.

In this embodiment, the electric winch 7 serving as a winding means and the battery BT serving as a power source are provided between the fixed casters 52 at one end of the frame 6 along the traveling direction. An operation switch 8 as an operating means for operating the winch 7 is disposed at a position slightly deviated from the center of the handle 61. The electric winch 7 includes a spool clutch 72 and an electric motor (not shown).
The spool 73 is detachably connected to the spool 73 through which a towing wire W1 as a towing string member having a necessary and sufficient length is wound. The spool clutch 72 is provided so as to be able to pull out the tow wire W1 without operating the electric motor, and also partially plays a role as an operating means, and can be manually connected and disconnected. A hook W11 for hooking is attached to the tip of the towing wire W1.

The battery BT has, for example, a charging function. When the engine 2 is operated to drive the power sprayer 1, the battery BT is charged by the power of the engine 2 via a charging circuit (not shown). ing. This is because it is not necessary to specially charge only the battery BT. If the battery BT is originally used for starting the engine 2 or the like, the battery BT may be used also as the power source of the electric winch 7.

The operation switch 8 is, for example, a momentary type that can be tilted to any of a winding position set on the electric winch 7 side and a feeding position set on the operation handle 61 side with the stop position as a middle point. When no operation force is applied, the motor automatically returns to the stop position. If the electric winch 7 and the battery BT are in the stop position,
Is disconnected, and the electric winch 7 is stopped. On the other hand, when operated to either the winding position or the feeding position, the direction of the current supplied to the electric motor is switched, and the electric winch 7 is set to the winding operation state or the feeding operation state.

Further, in this embodiment, a hook 9 as a fixing means is fixedly provided between the other end of the frame 6 facing the electric winch 7, that is, between the free casters 51, and the hook 9 is a fixing cord member. The fixing rope W2 can be locked. The manner of handling when the set dynamic jet 100 configured as described above according to the present embodiment is loaded and unloaded on the truck TR will be described below with reference to FIGS.

When loading the set dynamic jet 100 on the loading platform TR1 of the truck TR, the main set dynamic jet 100 is pushed to the vicinity of the truck TR, and as shown in FIG.
An electric winch 7 is mounted on a bridge BR that is laid so as to form a slope between the loading platform TR1 of the truck TR and the ground.
Are arranged to face each other. Next, the spool clutch is disengaged, the tow wire W1 is pulled out, and the hook H11 attached to the tip thereof is hung on the tow metal fitting K2 of the truck bed as the second fixed end. Thereafter, the spool clutch 72 is engaged, and the operation switch 8 is operated to the winding position by holding the operation handle 61. As a result, the electric winch 7 is wound up, and the set dynamic injection 100 is
Move to the R side, at that time, the set dynamic injection 100,
As shown in FIG. 4, the operation handle 61 is operated so as to be mounted on the loading platform TR1 along the bridge BR. And
After confirming that the set dynamic injection 100 is completely on the carrier TR1, the operation of the operation switch 8 is stopped. Next, as shown in FIG. 5, one end of the fixing rope W2 is hooked on the hook 9 disposed below the handle 61, and the other end is placed on the opposite side of the loading platform TR2 from, for example, the tow fitting K2. The first fixing end, which is the fixing metal fitting K1, is hooked. Thereafter, the operation switch 8 is operated to the winding position to wind the electric winch 7 until the towing wire W1 and the fixing rope W2 are tensioned with a constant tension. In this way, the traction force exerted on the frame 6 by the traction wire W1 and
The anti-traction force exerted on the frame 6 by the fixing rope W2 is antagonized, and the set dynamic injection 100 is transferred to the loading platform T of the truck TR.
Fix firmly on R1.

On the other hand, when lowering the set dynamic jet 100 from the loading platform TR1 of the truck TR, the operation switch 8 is operated to the extended position, the tow wire W1 is extended, and the fixing rope W2 is slackened and removed. The moving jet 100 is moved onto the bridge BR. Thereafter, the operation switch 8 is operated intermittently or continuously, for example, so that the towing wire W1 is drawn out at a desired speed, and the set dynamic jet 100 is lowered along the bridge BR. After the set dynamic jet 100 has completely descended to the ground, the operation switch 8
To the feeding position to slightly slack the towing wire W1, and to hook H1 from the towing bracket K2 of the loading platform TR1.
Remove 1 Then, the operation switch 8 is operated to the winding position to wind the towing wire W1, and the operation is completed.

Therefore, the set dynamic injection 1 according to this embodiment is
According to 00, since the electric winch 7 can be moved up and down along the bridge BR installed between the carrier TR1 and the ground simply by operating the electric winch 7, even an individual can perform the unloading operation. And the operation is
Basically, only the switching operation of the operation switch 8 is performed.
Very simple and less likely to cause operation errors. In addition, even if an operation error occurs, the set dynamic jet 100 is very safe because it is always connected by the towing wire W1. Furthermore, since the electric winch 7 or the like may be mounted by additional processing without changing the configuration of the existing set dynamic injection 100, the realization is extremely easy, and a significant increase in cost and weight is not caused. The point of not causing a significant increase in weight is a great advantage in that it does not hinder manual movement in the field, etc., and does not cause a significant increase in cost and can be realized by additional modification of the existing set dynamic jet. This is a great effect in the sense that it is easy to introduce for small and medium-sized farmers. In addition, since the actuator is the electric winch 7, there is an additional effect that the operation can be performed quietly.

Various other effects can be obtained. For example, the electric winch 7 can also be fixed on the truck bed TR1 and the work can be simplified. Further, since the operation switch 8 is attached to the operation handle 61, the operation switch 8 can also be operated while operating the traveling direction, and the operation as a whole can be easily performed.
Furthermore, since the electric winch 7 is operated only while the operation switch 8 is operated to the winding position or the feeding position by adopting a momentary type operation switch, the electric switch is operated only when the operation switch 8 is released. The winch 7 can be stopped, and the easiness and safety of the work can be secured.

The present invention is not limited to the above embodiment. For example, as the tow wire or the fixing rope, any bendable string member such as a cloth belt, a string, or a chain may be used as long as the strength permits. In addition, the present invention is not limited to the illustrated example, and various modifications can be made without departing from the gist of the invention.

For example, if the leading end of the towing string member is hung on the bed of the truck and the winding means is operated by operating the operating means, the bridge installed between the bed and the ground can be raised and lowered by itself. Also, the unloading work can be performed by an individual. Moreover, this unloading work,
Basically, only the operation means needs to be switched, so that it is very simple and does not easily cause an operation error. In addition, even if an operation error occurs, the set dynamic jet is always connected by the towing string member, so that the safety is high. Furthermore, since the winding means and the like may be mounted by additional processing without changing the configuration of the existing set dynamic jet, the realization is extremely easy, and there is no significant increase in cost and weight. The fact that the cost does not increase is a great advantage for small and medium-sized farmers, and the fact that it does not increase the weight is a great effect when hand-moving in a field or the like. Furthermore, since the winding means is electrically driven, it has an additional effect of being quiet.

A frame is provided with a fixing means which can be connected to a first fixed end set on a loading platform or the like, and this fixing means is connected to the first fixed end and a second fixing means is set on the loading platform or the like. By hooking the leading end of the traction string member on the fixed end and winding and stretching the traction string member by winding means, a traction force acting on the frame via the traction string member, If it is possible to antagonize the anti-traction force acting on the frame via the fixing means connected to the fixed end and fix it, for example, to fix the truck to the carrier during transportation, use the winding means. Can be done easily.

[0028] If the fixing means and the winding means are provided at the ends facing each other along the running direction of the frame, such fixing can be suitably performed.
If the fixing means is a hook and is configured to be connectable to the first fixed end via a fixing cord member, the realization is easy and the configuration is simple. The operating means is an operation switch capable of connecting and disconnecting the winding means and its power source, and if this operation switch is arranged on an operation handle provided on the frame, for example, traveling on a bridge In this case, the overall operation becomes extremely easy, for example, the winding means can be operated while the traveling direction is operated by the operation handle.

If the operating switch is a state in which the winding means and its electric power source are energized and operated only while receiving the operating force, the winding means is stopped simply by releasing the operation switch. It is possible to prevent the operator from forgetting to turn off the operation switch, and to enhance the safety in case of an erroneous operation. When the power source of the winding means is a battery, if the battery is charged by a drive source for driving the power sprayer, the trouble of specially charging only the battery can be omitted. become.
