Description

  TECHNICAL FIELD The present invention relates to a ship that can travel on a paddy field and spray fertilizers and herbicides, and more particularly relates to a spray ship in which a spraying hull is connected to the rear of the hull. It is.

  Conventionally, various small model ships in which fertilizers and herbicides are sprayed on paddy fields have been proposed. As shown in FIG. 7, such a ship generally has a hull 91 made of hollow resin or polystyrene foam, and a propulsion device 92 such as an engine or propeller provided on the cockpit of the hull 91. And a spraying device 93 that accommodates the material to be sprayed such as fertilizer and herbicide and sprays it on the paddy field. When such a ship is used, there is an advantage that fertilizers and herbicides can be sprayed near the center of the paddy field, and those objects can be sprayed by operating the remote controller.

Japanese Utility Model Publication No. 7-39457

  However, there are the following problems in the structure of such a conventional ship for spraying.

  That is, in such a conventional structure, it is necessary to prevent the propeller and the ladder from coming into contact with a shallow place, so that the propeller and the ladder are not provided on the ship bottom side. However, such a structure in which no propeller or ladder is provided on the bottom side of the ship makes rapid turning difficult because water cannot be drained with a keel or ladder. For this reason, in the past, when it was necessary to turn closer to the dredging, the direction was changed with the air ladder in advance while reducing the speed in front of the dredging. Turning the air ladder makes it difficult to turn. Therefore, in practice, the turning operation is performed with the engine speed increased, and the engine speed is decreased immediately after the rotation to reduce the speed, or the engine speed is increased for a moment as the aerial ladder is turned off. The operation of a person with a technique was necessary.

  Furthermore, as another problem, in conventional ships, a tank such as fertilizer and herbicide is provided in the center of the cockpit, but the fertilizer and herbicide in the tank decreases as the vehicle travels. As shown from the upper diagram to the lower diagram in FIG. 8, the bow gradually rises, the draft line becomes shorter, and the running stability becomes worse.

  Therefore, in order to solve the above-mentioned problems, the present invention makes it possible to turn quickly, and even when the remaining amount in the tank is reduced due to the spreading of the object to be spread, It aims at providing the ship for spraying which enabled it to secure property.

  That is, in order to solve the above-mentioned problem, the present invention includes a first hull having a propeller and an aerial ladder on a cockpit, and a container for accommodating the object to be dispersed. The second hull is provided independently, and the angle formed between the first hull and the second hull is changeable and connected by a connecting portion.

  If comprised in this way, it can make it easy to turn using the flow of water by changing the connection angle of a 1st hull and a 2nd hull, and it turns quickly compared with the case where it turns only by an air ladder. Will be able to. Further, since the accommodating portion is provided on the second hull side, the bow is not lifted even when the tank capacity is reduced, and there is an advantage that traveling stability can be ensured.

  In such an invention, the first hull and the second hull are separably connected to each other by the connecting portion.

  If comprised in this way, while being able to carry easily by isolate | separating each hull, only a 1st hull can be used as play equipment, such as a radio controlled boat.

  Further, the connecting portion is configured to include a driving portion for setting a connecting angle between the first hull and the second hull.

  If configured in this way, not only turning by an air ladder, but also forcibly setting the angles of the first hull and the second hull at the drive unit, and turning quickly in a desired direction by the flow of fluid in the part in contact with the water surface Can be made.

  Further, the connecting portion is freely rotated about the vertical axis.

  In this way, if the first hull can be freely rotated without providing a drive unit, the first hull can be pushed from the rear by the second hull at the moment when the angle of the first hull is changed by the aerial ladder. It becomes possible to turn quickly by forcibly changing the angle of the head.

  According to the present invention, in a spraying ship for spraying an object to be dispersed, a first hull having a propeller and an aerial ladder on a cockpit and a second ship having an accommodating part for accommodating the object to be scattered are independent. Since the angle between the first hull and the second hull is connected by the connecting portion so that the angle can be changed, the flow of water is utilized by changing the angle between the first hull and the second hull. This makes it possible to turn the hull quickly. In addition, since the accommodating portion is provided on the second hull side, even if the capacity of the accommodating portion is reduced, the bow is not lifted, and a merit that traveling stability can be ensured is obtained. You can also do that.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The spraying ship 1 in this embodiment is configured to spray a material to be sprayed such as fertilizer and herbicide while traveling in a paddy field. As shown in FIG. I'm trying to spray the scatter. Characteristically, the first hull 2 having the propeller 22 and the aerial ladder 23 and the second hull 3 for spraying the spread material such as fertilizer and herbicide on the paddy field are provided independently. The one hull 2 and the second hull 3 are connected so as to be rotatable by a connecting portion 4 around a vertical axis. Hereinafter, the configuration of the spraying ship 1 in the present embodiment will be described in detail.

  First, the first hull 2 is made of polyethylene having a thickness of about 1 to 5 mm, and has a hollow interior so that it can travel even in a shallow place such as a paddy field. Further, as shown in FIG. 3, no large flat protrusions such as a center board and a keel are provided on the bottom side of the hull so as not to contact the bottom of the paddy field. However, if a large protrusion is not provided on the bottom surface side in this way, contact with the bottom of the water can be prevented, but straight running stability and steering performance are lacking. It will be in a state of going straight ahead. For this reason, a plurality of concave portions 24 along the longitudinal direction of the ship bottom are formed without providing such flat protrusions on the ship bottom side.

  The propulsion device provided on the cockpit 20 of the first hull 2 includes an engine 21 driven by gasoline, a propeller 22 rotated by the engine 21, an aerial ladder 23 provided behind the propeller 22, and the like. Is done. Here, the driving device is constituted by an engine 21 driven by gasoline or the like, but a motor driven by a battery or the like may be used. On the other hand, the aerial ladder 23 provided behind the propeller 22 is configured to turn the first hull 2 and is provided at a certain distance from side to side. The actuator is driven by the remote controller 5 to turn. I try to let them.

  On the other hand, the second hull 3 is connected to the rear of the first hull 2 via a connecting portion 4 which will be described later. And a spraying part 32 for spraying. Here, not only liquid fertilizers and herbicides but also powdered fertilizers and herbicides may be used as the objects to be spread. At this time, a tank is used as the container 31 when spraying the liquid object, and a hopper is used as the container 31 when spraying the powder object. Moreover, as the spreading | diffusion part 32, it is made to make a to-be-dispersed material flow out to the water surface with the tube connected with the tank, and when spraying the powder-like to-be-scattered thing discharged | emitted from the hopper, a rotary blade is used. It is made to scatter on the surface of the water by constraining rotation. These accommodating portions 31 and the like are preferably arranged in the vicinity of the center of gravity position of the second hull 3 so that even if the remaining amount of the accommodating portion 31 is reduced, the second hull 3 Try to keep balance.

  Further, as shown in FIG. 3, a concave portion 33 is provided along the longitudinal direction on the bottom side of the second hull 3 in the same manner as the first hull 2. Further, as shown in FIG. 2, the bow side of the second hull 3 is V-shaped so as not to come into contact with the stern of the first hull 2 even when the bending angle with the first hull 2 is increased. Alternatively, it is formed in a U shape.

  The connecting portion 4 that connects the second hull 3 and the first hull 2 is configured to be rotatable about the vertical axis of the water surface. As such a connecting part 4, in the first embodiment, as shown in FIG. 2, the stern center of the first hull 2 and the bow center of the second hull 3 are connected by a hinge, Stretchable rod-like connecting members 41 are stretched on the left and right sides of the hinge so as to connect them. The connecting member 41 can be expanded and contracted in the axial direction by the drive unit 42. For example, when turning the scattering ship 1 to the right side, the right side connecting member 41 is shortened toward the traveling direction, and The connecting member 41 on the opposite side is lengthened (FIG. 4 (right turn)). On the other hand, when the spraying ship 1 is turned leftward, the connecting member 41 on the left side is shortened and the connecting member 41 on the opposite side is lengthened in the traveling direction (FIG. 4 (left turn)). As a result, the first hull 2 and the second hull 3 can be turned in the direction in which the first hull 2 and the second hull 3 are to be turned by the flow of fluid along the concave portion 24 on the bottom side. These left and right connecting members 41 can be expanded and contracted by the operation of the remote controller 5 by using a drive unit 42 such as a hydraulic cylinder, an air cylinder, a motor, or a slide type potentiometer, and independent of the operation of the air ladder 23. Alternatively, it can be expanded and contracted in conjunction with the operation of the aerial ladder 23. Specifically, when the aerial ladder 23 is changed to the right, the right connecting member 41 is shortened corresponding to the angle, and conversely, the left connecting member 41 is lengthened. Conversely, when the aerial ladder 23 is changed to the left direction, the right connecting member 41 is lengthened and the left connecting member 41 is shortened according to the angle. The connecting portion 4 is configured so that the first hull 2 and the second hull 3 can be separated, and a detachable plate 40 is provided on the first hull 2 side and the second hull 3 side. A connecting portion 4 including a hinge and a connecting member 41 is attached to 40. The first hull 2 can be used as a playground equipment, and the type of spatter can be changed by changing the type of the second hull 3.

  Next, a turning operation of the spraying ship 1 configured as described above will be described.

  First, in the case where the scattering vessel 1 is caused to travel straight to spread the material to be spread, the remote controller 5 is operated to drive the engine 21 and the aerial ladder 23 is directed straight ahead as shown in FIG. Then, the first hull 2 goes straight in the direction of the aerial ladder 23. At this time, water flows along the concave portion 24 on the bottom side of the ship, and straight running stability is ensured. Further, in the case of traveling straight in this way, the connecting members 41 attached between the first hull 2 and the second hull 3 are set to the same length, and the longitudinal directions of the first hull 2 and the second hull 3 are set. The axis of is straight. Thereby, the water which flowed along the recessed part 24 of the ship bottom of the 1st hull 2 flows along the recessed part 33 of the ship bottom of the 2nd hull 3, and can ensure the straight-running stability of the ship 1 for spraying. And while traveling the ship 1 for dispersion | spreading in this way, the remote control 5 is operated and a to-be-dispersed material is spread to a paddy field.

  Next, when the scattering ship 1 is turned to the right, as shown in FIG. 4 (right turn), the remote controller 5 is operated to turn the aerial ladder 23 to the right, and the first hull 2 and Of the connecting members 41 attached between the second hulls 3, the right connecting member 41 is shortened and the left connecting member 41 is lengthened. Then, the first hull 2 can be turned to the right by the aerial ladder 23 and the first hull 2 bends to the right of the second hull 3, so that the concave portions 24, 33 provided on the bottom of each hull are provided. The flow of water can be changed along. As a result, the spray ship 1 can be quickly turned to the right by the turning by the air ladder 23 and the turning by the flow of water due to the bending of the first hull 2 and the second hull 3.

  Conversely, when turning the spraying ship 1 to the left, as shown in FIG. 4 (left turning), the remote control 5 is operated to turn the aerial ladder 23 to the left, and the first hull 2 Of the connecting members 41 attached between the first hull 3 and the second hull 3, the right connecting member 41 is lengthened and the left connecting member 41 is shortened. Then, the first hull 2 can be turned to the left side by the aerial ladder 23 and the first hull 2 bends to the left side of the second hull 3, so that the first hull 2 is bent along the recesses 24 and 33 provided on the bottom of each hull. The flow of water can be changed. Thereby, the ship 1 for spraying can be quickly turned to the left by turning by the air ladder 23 and turning by the flow of water due to bending of the hull.

  <Second Embodiment>

  Next, the structure of the ship 1 for dispersion | spreading in 2nd embodiment is demonstrated. In the spraying ship 1 in the first embodiment, the rod-like connecting members 41 provided on both sides of the connecting portion 4 are expanded and contracted. In this embodiment, as shown in FIG. Without providing such a rod-like connecting member 41, the connecting portion 4 such as a hinge is freely rotated. Hereinafter, although the operation | movement of the ship 1 for spraying in 2nd embodiment is demonstrated, what attached | subjected the same code | symbol as 1st embodiment is demonstrated as what has the same structure as 1st embodiment. Omitted.

  First, when spraying the ship 1 for spraying and spreading the material to be sprayed, the engine 21 is driven by operating the remote controller 5 and the aerial ladder 23 is directed straight ahead. Then, the first hull 2 goes straight in the direction of the aerial ladder 23. At that time, water flows along the concave portion 24 on the bottom side of the ship, and straight running stability can be ensured. The second hull 3 is pulled straight by the driving of the first hull 2 and advances straight through the connecting portion 4, and at this time, water flows along the concave portion 33 on the bottom side of the second hull 3. The two hulls 3 also go straight ahead stably.

  Next, when turning the spray ship 1 to the right, first, as shown in FIG. 5A, the remote controller 5 is operated to turn the aerial ladder 23 to the right. Then, the first hull 2 turns to the right in the traveling direction by the aerial ladder 23. At this time, the speed of the first hull 2 in the straight traveling direction relatively decreases with the turning. On the other hand, since the second hull 3 is in a state of traveling straight, the second hull 3 pushes the stern side of the first hull 2 via the connecting portion 4 (the state of FIG. 5A). Then, the stern side of the first hull 2 is forcibly rotated by the pressing from the second hull 3 (FIGS. 5B and 5C), and the entire spraying vessel 1 can be turned quickly. .

  On the contrary, when the spraying ship 1 is turned leftward, similarly, the aerial ladder 23 is turned left and the first hull 2 is turned leftward. Then, the speed in the straight direction of the first hull 2 becomes slow, and the stern of the first hull 2 can be pressed by the second hull 3. Then, the first hull 2 can be quickly turned by this, and the spraying vessel 1 including the second hull 3 connected via the connecting portion 4 can be quickly turned to the left as a whole. it can.

  In this way, when the stern side of the first hull 2 is pressed by the second hull 3, if the aerial ladder 23 exists on the side close to the connecting portion 4, the first hull is weighted by the weight of the second hull 3. 2 may be difficult to turn. For this reason, as shown in FIG. 6, the second aerial ladder 23 f may be provided on the bow side of the first hull 2. If the second aerial ladder 23f is provided on the bow side of the first hull 2 in this way, the relatively free bow side can be swung to the left and right. The stern side can be pressed by the two hulls 3. When the aerial ladder 23 is provided on the bow side as described above, since the wind from the propeller 22 cannot be received, the aerial ladder 23 is provided behind the propeller 22 and the aerial ladder 23 is also provided on the bow side. Also good.

  As described above, according to the above-described embodiment, in the dispersion vessel 1 that disperses the object to be dispersed, the first hull 2 including the propeller 22 and the air ladder 23 provided on the cockpit 20 and the object to be dispersed are disposed. Since the 2nd hull 3 provided with the accommodating part 31 to accommodate is provided independently, and the angle which the said 1st hull 2 and the 2nd hull 3 make is connected by the connection part 4 so that change is possible, the 1st By changing the angle between the hull 2 and the second hull 3, the spraying vessel 1 can be quickly turned. Moreover, since the accommodating part 31 is provided in the 2nd hull 3 side, even if it is a case where the capacity | capacitance of the accommodating part 31 decreases, a bow will not be lifted and traveling stability can be ensured. Benefits can also be obtained.

  Moreover, the connection part 4 can be removed as a whole by removing the plate 40. Thereby, the first hull 2 and the second hull 3 can be separated to facilitate carrying. Further, only the first hull 2 can be used as a playground equipment, and the type of spatter can be changed by changing the type of the second hull 3.

  Further, as the connecting portion 4, a rod-like connecting member 41 is stretched, and the driving portion 42 for setting the connecting angle between the first hull 2 and the second hull 3 is provided. The angle between the first hull 2 and the second hull 3 can be forcibly changed by forcibly setting the angle of the connecting portion 4 and can be quickly turned in a desired direction by the flow of the fluid in the portion in contact with the water surface. it can. In particular, if the vehicle can be turned by simply changing the angle between the first hull 2 and the second hull 3 in this way, it is not necessary to increase the aerial ladder 23, and the influence of cross wind during strong winds can be suppressed. become.

  Moreover, when the said connection part 4 can be freely rotated like 2nd embodiment, at the moment when the angle of the 1st hull 2 changed with the aerial ladder 23, it is the 2nd hull 3 from the back. The stern of one hull 2 can be pushed, and the angle to which the first hull 2 faces can be forcibly changed to turn quickly.

  In addition, this invention is not limited to the said embodiment, It can implement in a various aspect.

  For example, in the above-described embodiment, the case where the length of the rod-shaped connecting member 41 is set as the drive unit 42 that adjusts the angle of the connecting portion 4 has been described as an example, but the rotation axis of the hinge-shaped connecting portion 4 is described. May be rotated by a motor to adjust the connection angle between the first hull 2 and the second hull 3.

  Moreover, although the said embodiment demonstrated the case where it drive | works a paddy field, it is applicable not only to this but the case where it drive | works a river, a lake, etc.

  Furthermore, in the above embodiment, the case where fertilizers and herbicides are sprayed has been described. However, the present invention can also be applied when spraying insecticides and the like. It can also be applied when spraying a remover or the like.

  In the above embodiment, the first hull 2 is provided with the aerial ladders 23, 23 f, but the aerial ladder is provided on the second hull 3 side to change the angle with the first hull 2 in an auxiliary manner. You may do it.
