Abstract

The utility model discloses a dressing irrigation saving injector which is composed of a sleeve barrel, a piston, a push rod, etc., wherein the bottom of the sleeve barrel is provided with a deep fertilizing needle and a feeding pipe. The deep fertilizing needle and the feeding pipe are respectively provided with a one-way valve, a push rod part in the sleeve barrel are penetrated with a quantifying pin used for extracting quantitative liquid fertilizer every time, the deep fertilizing needle is used for accurately and directly dressing near roots of crops for being convenient for the absorption of the crops, and the utilization rate of liquid fertilizer is enhanced. The utility model has the advantages of simple structure, convenient carrying and fast operation, and the utility model can be widely used for dressing liquid fertilizer for village families.

Description

The joint that topdresses is irritated syringe

The utility model relates to a kind of fertilizer placement drill, and the joint filling syringe that topdresses of saying so further belongs to manual agricultural equipment technical field.

At present, rural households normally directly water bottom crop with container with liquid when imposing liquid fertilizer to crops, this method imposes liquid fertilizer can not directly act on crop root, influences fertilizer and absorbs, so the fertilizer waste is serious, availability is low, and can not accurately measure.

The purpose of this utility model is to provide a kind of joint that topdresses to irritate syringe, and it can impose quantitative liquid fertilizer the root crops exactly, improves fertilizer utilization ratio, saves fertilizer.

For finishing above-mentioned purpose, the utility model structure is as follows: the piston type push rod is housed in graduated sleeve, the cover tube bottom is provided with deep placement pin and feed pipe, on deep placement pin and the feed pipe respectively device check valve is arranged, also be distributed with some jet apertures on the deep placement pin, the pusher section in sleeve leaves several through holes, be used for interspersed quantitative pin, can be at every turn plug-in mounting liquid fertilizer equally, return spring is enclosed within on the push rod by pin and socket cover location, flexible pipe will store up fertile device and feed pipe is linked together.

Good effect of the present utility model is: can quantitatively directly impose liquid fertilizer near crop root part exactly, being convenient to crop absorbs, improve fertilizer utilization ratio, in addition, insert quantitative pin on the push rod, can extract the liquid fertilizer of equivalent at every turn, operation is simple rapidly, return spring is located at outside the sleeve, has prevented fertilizer corrosion spring.

Further narrate the utility model below in conjunction with drawings and Examples:

Fig. 1 is the utility model principle assumption diagram.

With reference to Fig. 1, in the utility model: piston 2 and push rod 8 are housed in the sleeve 3, socket cover 6 is buckled on the sleeve 3, the bottom of sleeve 3 is provided with feed pipe 12 and deep placement pin 1, on feed pipe 12 and the dark real pin 1 check valve 13 is housed respectively, also be evenly distributed with several spray-holes 14 on the deep placement pin 1, some through holes 4 are left in push rod 8 lower parts in sleeve 3, and be inserted with quantitative pin 5, return spring 7 is enclosed within on the push rod 8, flexible pipe 9-termination feed pipe 12, the other end connects the fertile device 10 of storage by filter screen 11, and the fertile device 10 of storage can be made the soft body structure container that becomes band in implementation process.
