Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkler used for surface irrigation of upland fields, and is an underground burial type in which the spout of the sprinkler buried underground is automatically projected from the surface of the ground when necessary. Regarding hop up riser.

[0002]

2. Description of the Related Art As conventional examples of sprinklers used for surface irrigation of upland fields, there are those based on a surface stationary method, a land setting method, or a moving set method.

Among these, the sprinkler of the stationary surface type has a water supply pipe on the surface of the ground at the time of planting, and a ground start-up type sprinkler is attached to the water supply pipe at predetermined intervals. The device is disassembled and removed.

However, this sprinkler requires a troublesome assembling work and disassembling work each time it is planted and harvested.

Further, in the sprinkler of the embedding setting method, the water supply pipe is buried in the ground in advance, and a sprinkler is connected to the water supply pipe at a predetermined interval to start up from the ground surface. Since it is a stationary type, it does not require assembly work and disassembly work, but it obstructs the passage of tractors,
This significantly impairs the efficiency of cultivation work.

Further, the sprinkler of the moving set type is constructed by assembling and disassembling the sprinkler of the above-mentioned ground surface emplacement type for every sprinkling, and the cost can be reduced because the device can be used in other sprinkling areas. Of the above sprinkling methods, this is the most time consuming.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks of the conventional device, and the spout of a sprinkler device buried underground is of a vertically expandable type capable of rising to the ground. An object of the present invention is to provide an underground buried type hop up riser that is a permanent type, but does not hinder cultivation, by automatically projecting this spout to the ground as needed.

[0008]

In order to achieve the above object, an underground buried type hop up riser of the present invention has a water supply pipe connected to the lower end of an outer pipe vertically buried in the ground and at the same time as the outer pipe. A holding pipe is fixed to the upper end of the pipe, the inner diameter of the holding pipe is made smaller than the inner diameter of the outer pipe, and the rising pipe is slidably inserted into the inner diameter of the holding pipe, and a packing is provided on the outer periphery of the lower end of the rising pipe. Is fixedly attached to the outer tube so as to be slidably inserted into the inner diameter of the outer tube, and a jet nozzle having a small-diameter jet hole is detachably provided at the upper end of the rising tube.

[0009]

In the state before sprinkling of the underground buried type hop up riser of the present invention, the outer pipe is vertically buried in the ground and the rising pipe is also lowered, and the spout provided at the upper end of this rising pipe. The soil is covered above the mouth.

When water is supplied to the water supply pipe during water sprinkling, the lower end surface of the packing of the rising pipe and the lower end surface inside the holding pipe are pressed upward by the water pressure of the supplied water.

On the other hand, the supply water is ejected from the ejection holes of the holding pipe through the rising pipe to moisten the upper soil and soften it into a mud, so that the rising pipe pressed upward as described above is The softened soil above is pushed away and rises, and the holding tube at the upper end is projected from the ground.

Therefore, if the holding pipe protruding above the ground is removed from the rising pipe and a sprinkler is attached to the upper end of this rising pipe, it can be used as a normal sprinkler.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional view of an underground buried type hop up riser of the present invention. FIG. 2 is a vertical cross-sectional view showing a state of the underground buried type hop-up riser of the present invention buried in the ground during water supply. FIG. 3 is a vertical cross-sectional view showing a state in which the spout of the underground buried hop up riser of the present invention is raised from the ground.

In FIG. 1, the underground buried type hop-up riser of the present invention has a long outer pipe 1 vertically buried in the ground 9 and a water supply pipe 2 connected to the lower end thereof and held at the upper end of the outer pipe 1. The tube 3 is fixed.

The outer pipe 1 and the water supply pipe 2 can be connected to each other by providing male and female screws at both ends and screwing them together, and the outer pipe 1 and the holding pipe 3 can also be connected to both ends. It can be connected by screwing male and female screws provided on the section.

Further, the inner diameter of the holding tube 3 is made smaller than the inner diameter of the outer tube 1, the long standing tube 4 is slidably inserted into the inner diameter of the holding tube 3, and the lower end outer circumference of the rising tube 4 is packed. 5 is fixed and is slidably inserted into the inner diameter of the outer tube 1.

The packing 5 is composed of a packing holding metal 5a and a bowl-shaped packing 5b. The packing 5 is fixed to the outer circumference of the lower end of the rising pipe 4, and the inner circumference of the outer pipe 1 is moved along with the vertical movement of the rising pipe 4. It slides against.

Therefore, the rising pipe 4 is guided in the vertical direction by sliding along the inner diameter of the holding pipe 3 and the inner diameter of the outer pipe 1 through the packing 5, and the rising pipe 4 is lifted until it hits the holding pipe 3. You can That is, since the rising stroke of the rising pipe 4 is substantially determined by the length of the rising pipe 4 from the packing 5 to the inner lower end surface of the holding pipe 3, taking the rising stroke of the rising pipe 4 into consideration, The length of the riser 4 and the depth of the underground burial should be determined.

Further, a small diameter ejection hole 6a is formed in the center of the nozzle head 6 which is detachably provided by screwing or the like provided on the upper end of the rising pipe 4, and the outer peripheral shape of the nozzle head 6 is It has a tapered shape that tapers upward. This shape makes it easier for the spout 6 to push up the soil above and rise.

To install the above apparatus, as described above, the underground burial position is set in consideration of the rising stroke of the rising pipe 4, and the plurality of water supply pipes 2 are placed at desired positions in the watering area.
Is disposed in the ground, and a water supply source (not shown) is connected to each water supply pipe 2.

At the desired sprinkling position, the end of each water supply pipe 2 is exposed in a vertically dug hole, and the outer pipe 1 is vertically inserted into the end of the water supply pipe 2 with the rising pipe 4 inserted therethrough. Connect upwards.

In this apparatus, since the rising pipe 4 can move up and down freely between the ground and the ground, the uppermost position below the surface of the spout 6 at the upper end of the rising pipe 4 is cultivated by a tractor or the like. By setting the position such that the rising pipe 4 is lowered, it is possible to cultivate the ground surface without any hindrance.

When water is sprinkled by this apparatus, in the state before water sprinkling, since the rising pipe 4 is in a lowered state, the soil is covered above the spout 6. When the water supply source is opened and water is supplied, the predetermined water pressure of the supply water 7 pushes the lower end surface of the packing 5 of the rising pipe 4 and the lower surface inside the holding pipe 6 upward. On the other hand, the supply water 7 passes through the ejection pipe 6a of the holding pipe 6 through the rising pipe 4 and is ejected into the soil to moisten the dry soil above and soften it into a mud-like state.

Further, as described above, the rising pipe 4 pressed upward pushes away the softened soil on the upper side and rises by the stroke of the rising pipe 4, so that the holding pipe 6 is projected from the ground.

When the holding pipe 6 projecting above the ground is removed from the rising pipe 4 and a sprinkler (not shown) is attached to the upper end of the rising pipe 4, it can be used as a normal sprinkler.

When cultivating with a tractor or the like, the rising pipe 4 protruding to the ground surface is pushed down into the ground, and the position of the holding pipe 6 is lowered to a predetermined depth from the ground surface.

[0028]

As described above, in the underground buried type hop up riser of the present invention, this device can be buried in the ground in a permanent state, and at the time of cultivating, the uppermost end of this device. Since the spout nozzle of the rising pipe at the bottom can be kept down to a predetermined underground depth, it does not hinder the tilling of tractors, etc. The soil softens like mud, and the riser pipe automatically rises due to the water supply pressure, so that the softened soil above is pushed away and the spout is projected to the ground surface. A sprinkler can be attached to the upper end for normal watering.

After watering, the holding pipe at the upper end of the rising pipe can be lowered to a predetermined depth from the ground surface by pushing down the rising pipe protruding to the ground surface. It is possible to cultivate without hindrance.
