Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Field of the Invention The present invention relates to a configuration of a spray nozzle of a spray rod horizontally arranged at a front end of a self-propelled unmanned sprinkler.

(B) Conventional technology Conventionally, there are various types of spray nozzles of sprayers and watering devices so as to be able to spray in the form of a mist, a shower, a direct spray, etc., and each of them can be sprayed independently. The spray nozzles are arranged at regular intervals on the spray rod so as to uniformly spray a fixed width, and are used for watering seedling mats and the like.

(C) Problems to be Solved by the Invention However, even if a large number of spray nozzles are arranged on the spray rod as in the related art, since the spray is discharged in a conical shape from the spray nozzle, one spray nozzle is used. The sprays sprayed from the spray nozzles adjacent to the nozzle overlap each other in the middle, and when the spray amount and the spray pressure are different at the overlapping portion, uniform spraying is not performed, resulting in uneven spraying.

(D) Means for Solving the Problems The present invention has been made in view of the above points, and has the following configuration.

At the front end of the fuselage, the spray rods 17 project laterally on both sides horizontally, and the spray rod 17 is provided with a large number of spray nozzles 19, 19,. A notch 19b is provided, and an ejection hole 19c is provided at the center of the notch 19b.
Are provided so that each of the spray nozzles 19 ejects without overlapping each other.

(E) Embodiment of the Invention The purpose of the invention and the means for solving the problem are as described above, and the configuration of the embodiment shown in the attached drawings will be described.

1 is a front view of a self-propelled unmanned water sprinkler at the time of work, FIG. 2 is a side view of the same, FIG. 3 is a plan view of an operation panel, and FIG. 4 is a perspective view of a spray nozzle of the present invention.

The self-propelled unmanned sprinkler will be described with reference to FIGS. 1 and 2 as a whole. The main body of the control device is used. The main body is configured such that a battery 2, a take-up reel 3, an aligning machine 4, and a motor 5 are mounted on a body frame 1, and running wheels 7. The upper part is protruded and covered by the cover 6.

By supplying power from the battery 2, the motor 5
Is driven, and the take-up reel 3, the aligning machine 4, and the running wheels 7, 7, 7, 7 are driven by a sprocket fixed to the drive shaft of the motor 5 via a chain. However, the driving wheel 7 may be a dedicated traveling wheel so that it can travel on a rail laid in advance so that stable traveling can be performed.

At the front end and the rear end of the body frame 1, contact sensors 10
11 is provided, and when it comes into contact with the piles 12 and 13 provided at the end of the ridge,
The motor reverses or stops according to the work.

A nozzle unit A is provided on the front end of the body frame 1. The mounting plate 14 of the nozzle unit A is fixed to the body frame 1 with bolts 15, and a bracket 16 formed in a D shape is fixed to the mounting plate 14, and is supported on both sides of the lower horizontal rod 16 a of the bracket 16. The spray rods 17 supported by the rods protrude horizontally, and the support rods are rotatable in the front-rear direction about the base so that the spray rods 17 can be rotatably stored.

A lock plate 23 is pivotally supported at the center of the vertical rod 16b of the bracket 16, and a handle 25 is extended rearward on a pivot shaft on which the lock plate 23 is fixed, and the handle 25 rotates the lock plate 23. When the movable rod is movable, the fixed rods 21 erected on the support rod are fixed by a lock plate 23 so that the spray rods 17 do not swing.

Then, a wire 26 is provided between both ends of the upper horizontal rod 16c and the support rod.
-The 26 is interposed, and the spray rod 17 is lifted and supported.

An operation panel 33 is provided on the rear of the cover 6,
A handle 34 protrudes rearward and upward from both sides, and a work operation switch 29, an emergency stop switch, and the like are provided on a rear portion of the handle 34. A controller is provided inside the operation panel 33 to control traveling and spraying operations.
Above, as shown in FIG. 3, a battery checker 35 indicating whether or not charging is necessary, a power switch 36, a running changeover switch 37 for switching between a plurality of reciprocating watering operations and a single reciprocating controlling operation, and a case where the amount of sprayed medicine is small. One-way spraying
A changeover switch 38 for switching to reciprocating spraying in many cases, a reciprocating number setting device 39 for watering work, and a buzzer 40 are provided.

The spray rod 17 has spray nozzles 19, 19a,.
Are arranged at regular intervals, and as shown in FIG. 4, the spray nozzle 19 is detachable with a screw 19a,
The tip of the ejection part is provided with a "-" notch 19b at the center, and the angle of the notch 19b can be arbitrarily fixed, and is fixed obliquely at the time of watering work. An ejection hole 19c is provided at the center of the notch 19b. When sprayed from the spray nozzles 19, as shown in FIG. 1, the spray nozzles 19, 19,.

The spray nozzle 19 of the present invention is mainly used for watering work, and as shown in FIGS. 1 and 2, a large number of seedling mats 9, 9... Arranged neatly,
Move the unmanned sprinkler to the ridge and turn on the power switch 36
Then, the traveling changeover switch 37 is switched to the watering side, and the number of reciprocations is set by the reciprocating number setting device 39 so that a necessary amount of water can be sprayed on the seedlings.

Then, when the operation switch on the handle 34 is turned on, the motor 5 is driven to run, and at the same time, the solenoid valve is operated and opened to spray water from the spray nozzles 19. At this time, the spray nozzle 19 attached to the spray rod 17
From 19... Are sprayed obliquely and obliquely, and water is sprayed almost uniformly without overlapping with the next spray.

When the contact sensor 10 comes into contact with the pile 12 at the ridge end when the self-propelled unmanned sprinkler moves forward, the motor 5 rotates in reverse and moves backward, reaches the ridge end, and the contact sensor 11 contacts the pile 13. When the contact is made, the motor 5 is reversed and the number of reciprocations is counted. When the contact sensor 11 comes into contact with the pile 13 after the set number of reciprocations, the motor 5 is stopped, the solenoid valve is turned off, and the buzzer 4
0 sounds to signal the end of work.

(F) Effects of the Invention With the above configuration, the present invention has the following effects.

First, since the spray nozzle is attached to the spray rod in a diagonal direction from the spray nozzle, the spraying operation can be performed uniformly without overlapping each other.

Secondly, since the spray nozzle has a diagonal cut, the structure is simple and can be manufactured at low cost.
