Description
Technical field
The utility model is related to agricultural fertilizer machinery, be it is a kind of for plowing before ground mulching sow having of matching on demand
The fertilizer apparatus hydraulic circuit of machine fertilizer and chemical fertilizer.
Background technology
Before plowing, the cover type fertilising of earth's surface is an important agricultural production content.For many years, " apply fertilizer by rule of thumb " and make
Into following consequence：Chemical fertilizer is more, organic fertilizer is few, and nitrogenous fertilizer is more, potash fertilizer is few, and three elements fertilizer is more, trace element is few, and nitrogen, phosphorus, potassium ratio are lost
Adjust.Every year applies quantitative organic fertilizer to arable land, and improved soil organic component content is ploughing the organic principle in fertilizer
Played a role in ground, so as to reach the nutrient standard of soil plantation.Before plowing, by the granulated fertilizers such as organic fertilizer, chemical fertilizer one
Secondary property is applied the agriculture requirement that arable land surface is proportion fertilizer on demand by agriculture requirement ratio uniform.Proportion fertilizer can on demand for implementation
Improved soil composition, reduces fertilizer and wastes and pollution by chemical fertilizer, and reduces soil hardening, realizes soil sustainability farming.For
The job requirements that two kinds of fertilizer of organic fertilizer and chemical fertilizer apply in proportion, double case fertilizer applicators arise at the historic moment, the equipment for chemical fertilizer case and
Organic fertilizer tank, can in proportion contain different fertilizer, for the fertilizer in two fertilizer box to be applied into soil disposable before plowing
In.
By consulting literatures data, it is known that the state of the art of double case fertilizer applicators.(1) existing pair of case fertilizer applicator general character advantage
It is：Possess two fertilizer box of organic fertilizer and chemical fertilizer, can respectively contain different fertilizer, meet many fertilizer and disposably apply requirement, fertilizer
Case is provided with lower fertilizer amount manual adjustment means.(2) divided by power source, the kind of drive of existing pair of case fertilizer applicator fertilizer expelling shaft is main
There are two classes：The first kind is that power is taken turns from transport, and the rear-mounted defeated wheel of fertilizing equipment received shipment is mounted, using chain with tractor-drawn
Transmission drives fertilizer expelling shaft；Equations of The Second Kind is that, using big-powered tractor hydraulic pressure output driving hydraulic motor, hydraulic motor is passed by chain
It is dynamic to drive fertilizer expelling shaft.(3) two kinds of kinds of drive are contrasted, fluid motor-driven does not need clutch, than the structure letter of transport wheel drive
It is single；Fluid motor-driven can provide bigger driving torque, be easy to implement the fertilising requirement of big fertilizer amount.Therefore, simplify from structure
For power performance, fluid motor-driven mode is better than transport wheel-drive mode.(4) in the situation that other duty parameters are certain
Under (such as defertilizing opening aperture, the effective active length of fertilizer apparatus sheave, the timing of unit pace one), dose receives fertilizer distributor
The rotating speed influence of fertilizer expelling shaft, rotating speed is high, and dose is bigger；Conversely, dose is fewer.(5) existing pair of case fertilizer applicator is present altogether
Property defect, i.e. dose cannot precise controls：1. for the double case fertilizer applicators of transport wheel driving type, first, by transport wheel driving
Dynamic influence, the driving moment of its fertilizer distributor is smaller；Secondly, dose is directly proportional to transport wheel pace, i.e. tractor
Hauling speed is bigger, and dose is bigger；Conversely, dose is smaller.And tractor-drawn speed is grasped by state of ground and driver
Make influence larger.Therefore, the fertilizer amount of such fertilizer applicator is difficult to precise control.2. for the double case fertilizer applicators of hydraulic motor-driven
Speech, dose is directly proportional to motor rotary speed, and motor rotary speed is directly proportional to the flow of input motor, that is, be input into the fluid flow of motor
Bigger, dose is bigger；Conversely, dose is smaller.And on the one hand the flow for being input into motor is flowed by tractor hydraulic output
Amount influence；On the other hand the throttling speed control circuit using choke valve is larger by load effect, and Speed rigidity is poor.Therefore, such is applied
The dose of fertile machine is also difficult to precise control.
