[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sediment removal device for a pop-up sprinkler capable of removing accumulated sediment falling into a casing having an internal mechanism that moves up and down.

[0002]

2. Description of the Related Art Conventionally, a casing buried in the ground with its upper opening flush with the ground has a head cover above the casing which can match the opening of the casing and has an interface composed of main nozzles and blades. In a pop-up type sprinkler in which a null mechanism is provided so as to be movable up and down so as to protrude above the opening, the internal mechanism is detached from a slide bearing body at a lower part of the sprinkler to a casing outside during maintenance. .

[0003]

However, in this type of sprinkler, when the internal mechanism moves upward and operates, the earth and sand fall into the casing along with water from around the opening of the casing, and the bottom of the sprinkler enters the casing. If it accumulates, if it accumulates too much, it may bite into the slide bearing and cause a failure, or if sediment accumulates,
Although the internal mechanism is removed and then removed with a spoon or the like, it is troublesome and time-consuming, and the workability is poor, and the spoon or the like cannot be completely removed.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised to solve such a problem and to make it easy to take out earth and sand with a simple structure. In addition, a water-permeable container capable of receiving earth and sand falling from the opening is detachably mounted with bolts together with a slide bearing body at the lower part of the internal mechanism.

[0005]

Therefore, when earth and sand fall into the casing together with water from around the opening of the casing which is opened when the internal mechanism moves upward and operates, the water penetrates the container and is removed, and the earth and sand is removed from the container. It will be stored as it is received, as in the case of maintenance, remove the bolt and take out the container with the internal mechanism to the outside of the casing, it is possible to easily take out the earth and sand from the container as it is, The container can be easily attached to the casing with bolts together with the internal mechanism.

FIG. 1 is a sectional view of a pop-up sprinkler, in which a casing A is buried under the ground so that a flange 6 formed on the outer periphery of an upper opening a coincides with the ground E. Inside a casing lower part 7 extending downward, a snorkel 8, a slide shaft box 9, a piston 10, etc. extending to the inner peripheral side of the casing A are equipped. An internal cover comprising a head cover 1, which can be fitted above, a slide bearing body 4, a slide shaft 16, a main nozzle 2, a blade 3, a switching box 11, a switching lever 12, a lid plug 13 and the like which are fitted to the sliding shaft box 9. The mechanism B has the same structure as the conventional structure in which the mechanism B is vertically movable so as to protrude above the opening a. An inner peripheral opening edge inner peripheral upper with 15
A water-permeable container C capable of receiving earth and sand falling from the upper opening a so as to approach the upper outer peripheral surface of the slide shaft 16 is fitted to the bottom of the casing A, The bolt 5 which can be inserted and fixed from the flange 4a to the flange 9a of the slide shaft box 9 is inserted into the hole 17 at the bottom of the container C and can be fastened together.

An outer peripheral portion of a ring-shaped rubber droop 19 having a plurality of cuts 18 is fixed to an inner peripheral surface of an opening a which is an inner peripheral side of the flange 6 with which the head cover 1 coincides. As shown in FIG. 1, the rubber cover 19 is formed by the projections 20 on the lower surface of the head cover 1 where the head cover 1 moves downward.
Is pushed down, but as shown in FIG.
When the work moves upward, the rubber hang 19 is raised upward, so that it is possible to prevent earth and sand from falling through the opening a.

Therefore, as shown in FIG. 4, when the internal mechanism B moves upward and operates, the earth and sand fall into the casing A together with the water from around the opening a of the casing A. And water is permeated through the container C and sediment is stored, and the internal mechanism B is removed by removing the bolt 5 as in the case of maintenance.
At the same time, the container C is taken out above the casing A, the soil C can be easily taken out by tilting or washing the container C, and the internal mechanism B
At the same time, the container C can be put in the casing A and easily attached with the bolts 5.

[0009]

As described above, according to the present invention, when the earth and sand fall into the casing A together with the water from around the opening a of the casing A which is opened when the internal mechanism B moves upward and operates, the water is stored in the container. The soil and sand can be received and stored in the container C while allowing C to pass therethrough. At the same time as the maintenance, when the bolt 5 is removed and the container C is taken out of the casing A together with the internal mechanism B,
The earth and sand can be easily taken out of the container C, and the container C together with the internal mechanism B can be easily attached to the casing A by the bolt 5, so that the conventional structure can be easily solved by a simple structure. Features that can be used.
