Description

[Detailed description of the invention] [Industrial application field] This invention relates to a self-propelled spraying device that is mounted on a self-propelled trolley and sprays pesticides, seeds, etc. in fields. The present invention relates to a self-propelled spraying device that can streamline the work of changing the direction of the jet head in the left-right direction of the truck.

[Conventional technology]

In a conventional example of spraying pesticides, seeds, fertilizers, and other materials onto a field, a worker carries a power spreader on his back, grasps the sinking multi-nozzle head with one hand, and while walking in the field, sprays the sinking multi-nozzle jet while walking around the field. There is a way to spread more spray material. However, when the spray tank of a backpack-powered spreader is filled with spray material, the weight of the backpack-powered spreader can reach over 35 kg, making it difficult for workers to carry such heavy objects in fields with poor footing. Walking inside has become hard work.

Therefore, we installed a backpack power spreader on a self-propelled trolley,
There is a spraying method in which the spray material is sprayed from a multi-nosed spray head while a self-propelled trolley is running. In a conventional self-propelled spraying device that uses a self-propelled trolley, when changing the spreading direction of the spray material to the left or right with respect to the left-right direction of the self-propelled trolley, the operator must stop spreading the material and move the self-propelled trolley to the left or right. The operator then stops the vehicle, gets off the self-propelled trolley, and manually changes the direction of the multi-sink jet and adjusts it so that the nozzle of the multi-sink jet faces downward.
Furthermore, when storing the sinking multi-nozzle jet or when avoiding collision of the sinking multi-nosed jet with an obstacle while the self-propelled trolley is running, the worker must get off the self-propelled trolley and manually perform the flushing. It is necessary to operate the multi-orifice jet.

[The problem that the idea aims to solve]

With conventional self-propelled spraying equipment that uses self-propelled carts,
When changing the direction of the multi-sink jet in the left-right direction of the self-propelled cart, it is necessary to get off the self-propelled cart and manually change the direction of the multi-sink jet and adjust the direction of the nozzle of the multi-sink jet. This makes the work complicated. In addition, since the work requires time, the interruption time of the spraying work of the spray material becomes longer, and the total spraying time increases.

An object of the present invention is to provide a self-propelled spraying device that can easily change the direction of the jet head in the left-right direction of the self-propelled truck, and can also direct the nozzle of the jet head downward.

The object of the invention of claim 2 is to provide a self-propelled spraying device that achieves the object of claim 1 and is also capable of efficiently changing the nozzle to a retracted position and an extended position during operations such as storage. It is to be.

The operation of the embodiment will be explained.

When changing the direction of the sink multi-nozzle head 34 in the left-right direction of the self-propelled vehicle 10, the operator who is driving the self-propelled vehicle 10 in the driver's seat 14 must turn the first switch 80 on the driver's seat 14 to the first position. 1 electric motor 52
Turn on to the normal rotation position or reverse rotation position. As a result, the first electric motor 52 rotates, and the rotation shaft 48
is rotated by the rotational force transmitted from the first electric motor 52 via the gear device 50. In the first rotational joint 44, the upstream portion of the bent pipe 28 rotates relatively in the front-rear direction of the self-propelled vehicle 10 and around the axis of the jet tube body 24, and the downstream portion of the bent pipe 28 rotates in the vertical plane. is rotated around the axis of the rotating shaft 48, and the bent pipe 28
downstream part, proximal jet pipe 30, distal jet pipe 32
And the sink multi-mouth jet head 34 changes its position from one side to the other side in the left-right direction of the self-propelled truck 10. When the distal jet tube 32 is received in the receiver 42 of the column 40, the operator in the driver's seat 14 releases the first switch 80 and turns the first switch 80 off. As a result, power supply from the battery 86 to the first electric motor 52 is stopped, and the first electric motor 52
stops, and the rotation of the bent tube 28 around the axis of the rotating shaft 48 in the first rotational joint 44 also stops.

The nozzle 36 of the sink multi-mouth nozzle 34 is oriented downward in the position before rotation in the first rotary joint 44, but as the first rotary joint 44 rotates around the rotation axis line, the nozzle 36 faces downward. 1 rotational coupling part 4
In the position after rotation at 4, it faces upward. Therefore, the operator turns on the second switch 82 in the driver's seat 14 so that the second electric motor 56 is in the normal rotation position or the reverse rotation position. This allows the second
The electric motor 56 is driven, the gear 58 and the ring gear 60 are rotated, and the proximal jet pipe 30, the distal jet pipe 32, and the sink multi-mouth jet head 34 are rotated with respect to the bent pipe 28 at the second rotational coupling portion 54. Relative rotation around an axis. In this way, the sink multi-port nozzle 34 rotates about its axis, changing the nozzle 36 from upward to downward.

When storing the sinking multi-nozzle head 34 and when avoiding a collision of the sinking multi-nozzle head 34 with an obstacle while the self-propelled vehicle 10 is running, the operator in the driver's seat 14 switches the third switch 84 to the third electric motor. 78, turn it on to the normal rotation position. As a result, the third electric motor 78
rotates in the forward direction, and the electric cylinder 74 contracts to pull the ring 76 toward the center of the self-propelled truck 10.
The distal jet pipe 32 swings upward relative to the proximal jet pipe 30 around the hinge 70, and the distal jet pipe 32 and the sink multi-mouth jet head 34 protrude to the side of the self-propelled cart 10. From this position, it becomes a standing position and is pulled into the inside of the self-propelled trolley 10. When spraying the material 38 or passing an obstacle, the third switch 84 is turned on to the reverse position of the third electric motor 78, the electric cylinder 74 is extended, and the distal jet pipe 32 is opened. , the hinge 70 swings downward relative to the proximal ejection pipe 30 so that its center line coincides with the proximal ejection pipe 30 . Thereby, the sink multi-mouth jet head 34 is in a position protruding to the side of the self-propelled truck 10.

In the illustrated embodiment, the second rotational coupling portion 54 is configured at the connection portion between the bent tube 28 and the proximal injection tube 30;
It is also possible to configure it at the connection part between the sink 2 and the sink multi-mouth nozzle 34. Similarly, the bendable portion 72 may also be configured at the connection portion between the self-propelled trolley 10 and the sink multi-mouth nozzle 34.

In the invention of claim 1, the connection member is connected to the first rotary coupling portion and the second rotational coupling portion by an operation from the driver's seat of the self-propelled trolley.
At the rotation joint of the self-propelled vehicle, the front and rear directions of the self-propelled vehicle rotate around the axis of the jet tube barrel and the axis of the bent pipe, and the jet head changes the horizontal position of the self-propelled vehicle, and the nozzle of the jet head is rotated downward. do. Therefore, it is possible to perform the work of changing the direction of the jet head in the left-right direction of the self-propelled cart without stopping the self-propelled cart or having the worker get on or off the self-propelled cart, and without relying on manual labor. This makes it possible to simplify the work and improve efficiency. Further, as the time required for changing the direction of the jet head is reduced, the time required for the entire spraying operation can also be reduced.

In the invention of claim 2, the connecting member is provided with a bendable portion, and the bendable portion is bent from the driver's seat of the self-propelled vehicle via an actuator, thereby retracting the jet from the side protruding position of the self-propelled vehicle.
