Abstract

The utility model relates to an underground water injecting device for crops, which comprises an injecting head [1], a rotating handle [3], a piston [4] and a connecting rod [10] thereof. The utility model is characterized in that the part above the tip of the injecting head [1] is a hollow cavity body; the piston [4] with a water outlet [9] is arranged in the cavity body; the piston [4] is connected with the rotating handle [3] through the connecting rod [10]; the upper part of the injecting head is communicated with the cavity body and is provided with a water inlet [6]; the periphery of the bottom of the cavity body of the injecting head [1] can be superposed on the water outlet [9] of the piston, and the superposed position is provided with an injecting head water outlet [5]. When the utility model is utilized to carry out underground construction with small water depth, compared with traditional irrigation, water is saved by 90%. The utility model has simple structure and convenient operation; when the utility model is used in a vinyl house, water can be saved, ground temperature can be improved and air humidity in the vinyl house can also be lowered. The utility model can reduce the occurrence of insect pests and is suitable for the water injection and fertilizing operation of agronomic crops, such as fruit trees, melons, vegetables, etc., and vinyl house crops in mountains where water resources are rare.

Description

Crops underground flooding device

Technical field

The utility model relates to a kind of apparatus of annotating fertilizer for the crops underground flooding.

Background technology

Traditional crop irrigation is ground furrow irrigation or flood irrigation, and is both time-consuming, causes the significant wastage of water resource again, and particularly in the arid area of water resource famine, it is important that water-saving irrigation project, method and utensil more seem.

Summary of the invention

The purpose of this utility model is that the crops underground flooding device operated is convenient in a kind of water saving of design again, can be used for crops, fruit tree, the water filling of melon dish, fertilising operation that various bare areas and booth are planted.

The utility model comprises head [1], turning handle [3], piston [4] and connecting rod [10] thereof, it is characterized in that the most advanced and sophisticated above hollow cavity that is of head [1], be provided with the piston [4] of taking the mouth of a river [9] out of in the cavity, piston [4] is connected with turning handle [3] through connecting rod [10], head top is communicated with cavity water inlet [6] is set, and head [1] cavity bottom periphery can be provided with head apopore [5] with piston delivery port [9] place of coincidence.

According to crop species and homework type, for regulating the degree of depth of injecting soil, spacing anti-overflow dish is housed in the connection of head middle part, when the mulch film section was operated, anti-overflow dish installation direction was that convex surface is downward, in order to avoid the anti-overflow web is along crushing mulch film; Anti-overflow dish convex surface upwards during the bare area operation.

Utilize the utility model to carry out the underground little depth of water and execute, than traditional irrigation water saving 90%, simple in structure, easy to operate; Use not only water saving in the booth, can also improve ground temperature, reduce air humidity in the canopy, the generation that can alleviate damage by disease and insect greatly is applicable to the crops such as mountain region fruit tree, melon dish of water resources shortage and the water filling fertilising operation of greenhouse crops.

Description of drawings and embodiment

Accompanying drawing is a structural representation of the present utility model.

Referring to accompanying drawing, both sides, head 1 upper end are equipped with handle 8, and it is entity that head 1 inserts the tip, is Tong formula hollow cavity more than the tip, place piston 4 in the cavity, and piston 4 outer walls have delivery port 9, and its cross section is flap, and piston 4 is connected with turning handle 3 by connecting rod 10.The peripheral place of head 1 cavity bottom is provided with head apopore 5, and when turning handle 3 rotations make piston water outlet breach overlap with head apopore 5, water will flow out.Head 1 top is communicated with cavity water inlet 6 is set, and water inlet 6 is connected with feed pipe.Inject for regulating the degree of depth of soil, at the head middle part spacing anti-overflow dish 2 is installed, the through hole corresponding with the head cavity left in anti-overflow dish 2 centres, and spacing anti-overflow dish 2 and head 1 are for being threaded, and with adjusting insertion distance, linkage section is peripherally equipped with protective sleeve 7; During the bare area operation, anti-overflow dish 2 convex surfaces make progress, plastic mulching place water flood operations, and convex surface is upwards.

Claims (2)
