Abstract

The present invention be a kind of in the plant roots in soils device of control infiltration automatically.Be characterized in by the power source start-up control breaker that is subjected to water-swelling material.

When the plant roots in soils water deficient, the earth of lack of water siphons away the limited moisture in the water-swelling material that is subjected in the gauge tap naturally, and the piston switch lock of this device is promptly opened automatically, makes its water supply plant absorbing.When the plant roots in soils reached suitable humidity, gauge tap then cut out the water source automatically, thereby had guaranteed that plant growing needs the normal supply of water.

Description

The automatic control water supply installation of the plant roots in soils

The present invention relates to a kind ofly in the plant roots in soils, seep water off and on, particularly can need water and control the device of its water supply automatically according to plant growing.

The moisture content that plant growing absorbs generally obtains from manual watering or day rainfall; its water absorption course regular meeting runs into such problem; the moisture content that obtains by day rain is often not prompt enough; its workload of manually watering is tired heavy; moreover the moisture content that the two obtained all has an enough uniform defect, therefore usually influences the normal supply of the required moisture content of plant growing.

In order to address this problem, usual way is that water pipe is connected the running water spray, though this method can alleviate its workload effectively, this method has its weak point, water pipe behind the water receiving is not easy to move spray, therefore is difficult to implement this operation for large-area economic crops.

The objective of the invention is to provide a kind of device of the automatic control water supply in the plant roots in soils, it not only can in time be transported to moisture in the needed zone of plant root, and can control its too much or not enough defect that supplies water effectively.

Invention is achieved in that burying one in the other earth of plant roots connects the automatic control water supply of running water and the device of cutting off the water, this device have soakaway trench and in have the automatic control that splashed by water to rise material to supply water breaker, when the moisture content of the plant roots in soils was enough, gauge tap then blocked the water source automatically; When moisture content is not enough, stop the water source to be opened automatically by the breaker of switch, the plant roots in soils promptly has moisture content to infilter, thereby guarantees the normal supply of plant suction.

The present invention is because only need the moisture content of controlling plant root soil, make plant keep suitable moisture absorption, so its structure is not very complicated, because the starting point of invention is according to the plant roots in soils temperature difference, what make gauge tap is splashed by water to rise material to be subjected to the different influence of moisture content deal and the different pressure source that forms, so realize that easily the water source is by gauge tap or suitably stop to supply water and obtain automatic controlling plant root soil and remain on suitable humidity requirement.

Fig. 1 is the profile of the automatic control water supply installation of the plant roots in soils of proposition according to the present invention.

Describe the details and the working condition of the concrete device that proposes according to the present invention in detail below in conjunction with Fig. 1.

This device has a soakaway trench (1), in have the sieve shape aperture (2), what have outward that one deck is covered with aperture (2) is permeable layer (3), soakaway trench is hollow shape in (1), after the water source flows to here, ooze out behind the aperture in the earth outside the permeable layer, this permeable layer (3) has to subtract to be helped current and prevents sandy soil from entering in the soakaway trench (1) and influence the effect of its normal water supply.Being connected with it is gauge tap (4), the control water source is a piston switch lock (5) that can move up and down, next door projection is the fin (6) of limited piston breaker (5) scope of activities below it, there is an axle (7) at piston switch lock (5) center, its next door is splashed by water to rise material (8), be to intercept the interlayer (9) that splashed by water to rise material (8) scope of activities at gauge tap (4) hypomere 1/3 place, there is aperture (10) in gauge tap (4) shell stage casing, and there is permeable layer (11) to be covered with, the axis of the piston (7) has a spring (12), also has a cap nut (13), can rationally adjust Luo silk cap (13) according to the required humidity of the plant roots in soils, make spring (12) reach suitable elasticity.Gauge tap (4) is divided into three sections, and separable place is 1/3, and this section has thread, can pull down 1/3 section of gauge tap (4) when needing to adjust the plant roots in soils humidity to get final product.What connect running water is a slat gum flexible pipe (15), and this pipe has one to be connected short tube (14) with soakaway trench (1) junction, and it has thread.Rubber hose (15) front end has a water receiving pin made of copper (16), this pin has two projection joints (17), its effect is to insert to be difficult for dropping behind plastics or the rubber running water pipe and to connect the diversion source quick, and it is the hole (18) of cutting sth. askew that pin is chewed, and can arbitrarily insert the running water pipe water receiving.

In addition, splashed by water to rise material (8) when the plant roots in soils reaches suitable humidity in the gauge tap (4), its volume enlarges it has sucked enough moisture content from earth after, because of the tension of splashing after its expansion has been broken piston switch lock (5), make it tightly suppress rubber hose (15), enter in the soakaway trench (1) thereby block the water source.When the moisture content of the plant roots in soils was not enough, the root thing root of lack of water soil can rise splashing, and limited moisture content siphoned away in the material (8), and this is splashed by water to rise material promptly to form shrinkage phenomenon, tightly break piston switch lock (5) thus the power source disappeared; The spring (12) that also has the axis of the piston (7) tail can draw back the piston switch lock (5) that presses rubber hose (15) naturally, and the water source intestines that are obstructed have led to, and the plant roots in soils promptly has moisture content to infilter, thereby guarantees the normal supply of plant suction.

The fibers material manufacturing that also has the permeable layer of this device to damage with not being subject to the moisture content maceration; The material that splashed by water to rise material to use to have after the suction certain expansionary force and sopped up moisture content by earth is easily made: as bentonite etc.

Claims

1, characteristics of the present invention are the needs according to the plant roots in soils different humidity, and control the device that supplies water or cut off the water automatically, and there is a water source gauge tap (4) its soakaway trench (1) back, and what connect running water is a slat gum flexible pipe (15), it is characterized in that:

A. described soakaway trench (1) have the sieve shape aperture (2), in one deck permeable layer (3) is arranged;

B. this soakaway trench (1) with one automatically the control switch (4) that supplies water, cut off the water connect, in be subjected to the water material that rises of splashing;

C. to connect what draw running water be a slat gum flexible pipe to this device, and its front end is water receiving pin (16).

2, device according to claim 1 is characterized in that the gauge tap of this device is subjected to the different influence of the plant roots in soils moisture content deal, makes splashed by water to rise material (8) to form to shrink or the power source of expansion and pull switch lock in the gauge tap.(2) make it make the reaction of cutting off the water or supplying water, thereby guarantee the normal supply of plant suction.The spring (13) of the axis of the piston tail (12) plays the effect of mobile piston breaker (6) in addition.
