Description

[Detailed description of the invention] (a) Industrial application field The present invention is a hose that can be attached to a power sprayer, etc. and automatically wind up or send out the spray hose connected to the discharge port by remote control. This invention relates to an automatic take-up and delivery device.

(b) Prior art Conventionally, the technology related to automatic switching winding devices has been known as disclosed in Japanese Utility Model Application Publication No. 57-165269, and there is also a technology using a one-way clutch in a switching winding device for long objects. , Utsukai Showa 54-26097
The technique described in the above publication is known to the public.

(c) Problems that the invention aims to solve As mentioned above, in the past, the spray hose could only be rolled up, so if the spray hose was pulled out during work, the chemical solution filled in the spray hose would Due to the weight of the handle and the friction with the field when it is pulled out, the longer it is, the greater the resistance when pulling it out, which requires greater force.

(d) Means for solving the problems In view of the above points, the present invention is constructed as follows.

A drum 3 and a motor 4 capable of forward and reverse rotation are disposed in the frames 1, 1, and an alignment machine 5 and a sending device 14 are attached to the upper part of the frame 1. and a winding and sending device capable of driving the sending device 14,
A sprocket shaft 31 is fitted into one end of the drum shaft 3a of the drum 3 via a one-way clutch 30, and a sprocket 26 inside the one-way clutch is provided at the end of the delivery roller 15 of the delivery device 14.
The configuration is such that the delivery roller 15 rotates idly during winding, and the drum shaft 3a rotates idly during delivery.

(E) Embodiment The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the structure of the embodiment shown in the attached drawings.

FIG. 1 is a side view of the take-up and delivery device of the present invention. Figure 2 is also a plan view. FIG. 3 is a front sectional view of the drum shaft drive section.

The winding and sending device of the present invention is for performing pest control work and watering work by connecting to a set movable jet or directly to a water faucet.
1 is erected, support frames 2, 2 are horizontally mounted at the center of the frames 1, 1, and a drum shaft 3a of a drum 3 is rotatably mounted at the center of the support frame 2. As shown in FIG. 3, one end of the drum shaft 3a is connected to a sprocket shaft 31 via a bearing type one-way clutch 30.
The structure is such that the drive force is transmitted in one direction only, and the drive rotates idly in the opposite direction. An input sprocket 32, a traverse drive sprocket 33, and a delivery drive sprocket 34 are fixed to the sprocket shaft 31.

Further, a motor 4 capable of forward and reverse rotation is provided on a base 6 at the lower part of one side of the frame 1, and power is supplied to the input sprocket 32 via a chain 36 from a sprocket 35 fixed to a drive shaft 4a of the motor 4. can be conveyed. Further, power is transmitted via chains 37 and 38 to the alignment machine 5 installed horizontally at the upper part of one side of the frames 1 and 1, and the delivery device 14 installed at the upper part of the other side. Power for the motor 4 is obtained from a generator or battery attached to the engine.

The alignment machine 5 has a traverse shaft 10 horizontally mounted on the case.
A sprocket 25 is fixed to one end of the sprocket, and power is transmitted from the traverse drive sprocket 33 to the sprocket 25 via a chain 37. A sliding body 11 is fitted into the traverse shaft 10,
The spray hose 9 is inserted into the sliding body 11 with a guide pulley 12 pivotally supported, and the sliding body 11 is slid from side to side by rotation of the traverse shaft 10 to align the spray hose 9 during winding. However, it also rotates and slides during delivery.

Further, a receiver 7 is arranged on the top surface of the alignment machine 5,
The receiver 7 receives control signals for sending, winding, and stopping from a transmitter held by an operator during spraying work, and rotates the motor 4 forward, reverse, or stops.

A delivery device 14 is disposed at the upper part of the other side of the frames 1, 1, and the delivery device 14 supports a delivery roller shaft 15 below the frame 1, and has a sprocket 26 inside a one-way clutch fixedly attached to the end thereof. However, it is driven by the power from the chain 38, and the one-way clutch is configured to transmit power only when rotating in the delivery direction, and to idle when rotating in the reverse direction.

A large-diameter friction roller 15a is fixed at the center of the delivery roller shaft 15, and a presser frame 16 is fixedly installed above the frame 1, supporting rollers 17 and 18 around the shaft. Springs 19 and 20 are fitted into the shafts 17a and 18a at both ends of the presser rollers 17 and 18 to urge them downward.

That is, the friction roller 15a and the presser roller 1
When the spray hose 9 is inserted between 7 and 18 and sent out, this prevents any loss due to slippage. In addition, a support pulley 21 is provided in front of the frame 1,
22 protrudes, and guide rollers 23, 2 are placed in the center.
4 to guide the spray hose 9.

(f) Effect of the invention With the above-described configuration, the spray hose 9 is wound around the drum 3 and passed between the guide pulley 12, the presser rollers 17 and 18 and the friction roller 15a, and between the guide rollers 23 and 24, and the work is started. When the send button on the transmitter is pressed, the signal received by the receiver 7 causes the motor 4 to rotate in the direction of arrow B, causing the sprocket 35 to move from the chain 36, the input sprocket 32, the send drive sprocket 34, the chain 38, and the sprocket 26 to Delivery roller 1
5 is rotated, and the spray hose 9 is rotated by the holding rollers 17 and 18 and the friction roller 15a.
It is pulled in the direction. At this time, the alignment machine 5 is also sliding, and the drum 3 is idling due to the one-way clutch 30.

Next, when you finish work or return from the field end, press the wind-up button on the transmitter, and the motor 4 will rotate in the A direction, transmitting power to the sprocket 35, chain 36, and input sprocket 32, and drive the drum shaft 3a.
At the same time, the chain 37 is rotated by the traverse drive sprocket 33, the traverse shaft 10 is rotated by the sprocket 25, and the sliding body 11 is slid from side to side.

At this time, the sprocket 26 is also being rotated via the chain 38, but the one-way clutch installed in the sprocket 26 causes the delivery roller 15 to rotate idly.

(G) Effects of the invention Due to the above-described structure and operation, the present invention has the following effects.

First, since winding and feeding are performed by a motor, the force required for winding and feeding is small.
The labor required by the operator was reduced, and spraying work could now be carried out by one person.

Second, since the automatic hose take-up and delivery device is an independent device, it can be attached to a conventional sprayer, and no special modifications are required for installation.

Thirdly, during delivery, the drum 3 rotates idly,
Since only the sending device 14 and the alignment machine 5 are driven,
Smooth delivery operation of the spray hose 9 can be performed without using extra power.

Fourthly, during winding, the drum 3 and alignment machine 5 are driven and the delivery device 14 idles, so even in this case, accurate winding can be performed without using extra power.
