Description

A kind of Agricultural organic fertilizer fertilizer applicator
Technical field
The present invention relates to a kind of fertilizer applicator more particularly to a kind of Agricultural organic fertilizer fertilizer applicators.
Background technique
Organic fertilizer refers to containing organic substance, can provide a variety of inorganic nutrients of crops and organic nutrient and training A kind of fertilizer of fertilizer improvement soil.Wherein the overwhelming majority is gathered materials on the spot for farmers', and voluntarily product is made.Organic fertilizer is rich in organic matter Nutriment needed for matter and plant growth can not only provide nutrient needed for plant growth, improve soil, can also improve crop Quality improves crop yield, promotes high crop yield stable yields, preservation of fertility, while utilization rate of fertilizer can be improved, and reduces production Cost.Fully and rationally using organic fertilizer can increase crop yield, culture fertility, improves quality of agricultural product, improves soil nutrient Validity.
In China, master's organic fertilizer to be used is with vinasse, vinegar grain, manioc waste, sugar residue, furfural dregs, chicken manure, cattle and sheep horsehit It is main.The amount of spreading fertilizer over the fields is relatively much bigger every time relative to inorganic fertilizer for organic fertilizer, and generallys use artificially applying fertilizer for organic fertilizer China Mode, but artificially applying fertilizer the problems such as there is low efficiency, large labor intensity, recruitments more, at high cost.Since organic fertilizer is usual In fertilizer pond between field, its own viscosity is big, and impurity is more, easily blocking and corrosion delivery pump and pipeline, there is no on the market Organic fertilizer applicator that can be practical.Organic fertilizer application, with the development of appropriate scale of operation agricultural practices, compels to be essential based on artificial Solve the problems, such as the mechanization of organic fertilizer application.
Summary of the invention
In order to solve problem above, high-efficient the object of the present invention is to provide a kind of labor intensity is low, structure letter Single, power resources are convenient, and the pressure of fertilising is sufficient, corrosion-resistant, be not easy to block up, and can convey the agricultural of the viscous mixture for having impurity has Machine fertilizer fertilizer applicator.
In order to achieve the goal above, the technical solution adopted by the present invention:
A kind of Agricultural organic fertilizer fertilizer applicator, including cabinet body, piston pump and fertilization gun;Cabinet body is the supporter of piston pump, living Plug pump is the transmission mechanism of fertilizer applicator, draws and convey viscous mixture, the viscous mixture conveying that fertilization gun is used to convey To between field.In the present invention, transmission mechanism uses piston pump, and relative to traditional centrifugal pump is used, material and piston be not direct Contact, solves the problems, such as anti-blocking anti-corrosion, and in addition the discharge pressure of piston pump is bigger, can convey the paste liquid of impurity, And then convenient for the conveying of the sticky organic fertilizer liquid contained a large amount of impurities.
On the mobile device, the piston pump is mounted in the cabinet body, the feed liquor of piston pump pumping cylinder for the cabinet body installation Mouth is connected into fertile pipeline, and liquid outlet connects the feed inlet of fertilization gun by fertilizer producing tube road, is provided with peace on the piston pump pumping cylinder Fertile pipeline is let out in full valve, the safety valve connection, and the piston pump top is provided with pressure gauge.After the completion of safety valve is for applying fertilizer, It is discharged into remaining viscous mixture in fertile pipeline, is discharged into after safety valve from letting out fertile pipeline into the viscous mixture in fertile pipeline In fertilizer pond, organic fertilizer has on the one hand been saved, has on the other hand prevented the pollution of organic fertilizer.Pressure gauge has been convenient for user to see at any time Examine the pressure condition in piston pump pumping cylinder.
The fertilization gun includes fertilising pipe, the handle for being mounted on tube top end of applying fertilizer, is mounted on the foot-operated of fertilising pipe lateral wall Plate and connection fertilising tube bottom end pipette tips, it is described fertilising tube bottom end side wall on offer multiple fertilizer applying holes.Viscous mixture from The feed inlet of fertilization gun enters, and the Guan Houcong fertilizer applying hole that applied fertilizer enters in soil, is the plant fertilising in soil;Handle is convenient for User carries and installation fertilization gun;It is fixed in soil that foot pedal and pipette tips have been convenient for user to be inserted into fertilization gun.
Further, the mobile device is tractor, the power intake connection tractor of the piston pump is moved Power output end.Cabinet body and piston pump are mounted on tractor, fertilizer applicator conveniently moving is made, be convenient for user to different fields and The fertilising in different fertilizer pond;Power resources using the power output end of tractor as fertilizer applicator, power resources are convenient, are not required to It wants special electric energy to drive piston pump, keeps its easy to install and use.
Further, the top of the piston pump pumping cylinder is connected with double end nipple, inner thread elbow and high pressure in turn Hose, the high-pressure hose connect pressure gauge, and set-up mode in this way is not only convenient for monitoring pipeline stem pressure, but also energy Influence of the vibration equipment to pressure gauge is reduced, is read more acurrate.
Further, the upper end of the safety valve is connected in turn outside direct outer silk, stainless steel inner thread elbow and double end Fertile pipeline, set-up mode in this way, when pressure is more than pipe are let out in silk drainage joint, the outer silk drainage joint connection of the double end Road, equipment pressure-resistant range when, fertilizer returns to fertilizer pond from fertile pipeline is let out, and is effectively protected equipment safety.
Further, the fertilising pipe and handle are stainless-steel pipe, the outer surface of the handle is provided with annular knurl. Using stainless-steel pipe, fertilization gun is made to have enough intensity, it is therefore prevented that fertilization gun Long Term Contact liquid causes to get rusty;Outside handle Surface is provided with annular knurl, operates convenient for user hand handle to fertilization gun.
Further, the foot pedal bottom end is connected with support plate, foot pedal is supported, foot pedal is fastened, it is therefore prevented that Foot pedal is caused to damage since user overexerts.
Further, the pipette tips are conical structure, convenient for fixing fertilization gun in pipette tips insertion soil.
Further, the left and right ends of the handle are provided with rib, the little finger of toe of user is blocked, is used convenient for user double Pipette tips are inserted into soil by hand force.
Beneficial effects of the present invention:
The present invention applies fertilizer by using fertilizer applicator, relative to the mode of conventionally employed artificially applying fertilizer, fertilising effect of the invention Rate is high, user's labor intensity is low, recruitment is few, at low cost;
Fertilizer applicator of the invention, transmission mechanism use piston pump, and relative to traditional centrifugal pump is used, material and piston are not It directly contacts, solves the problems, such as anti-blocking anti-corrosion, in addition the discharge pressure of piston pump is bigger, can convey the pulpous state liquid of impurity Body, and then convenient for the conveying of the sticky organic fertilizer liquid contained a large amount of impurities;
