Abstract

The utility model relates to a rapid fertilizer filler, which belongs to an agricultural implement for agricultural fertilization. The utility model is suitable for fertilizing liquid fertilizer for single plant crops, when operation is carried out, a gun tip with a fertilizer spraying hole is inserted into soil, liquid fertilizer is injected into soil by a connecting rod communicated with a back barrel of a spraying machine, a hollow rod and an opening valve, when the connecting rod is free from pressure, the fertilizer spraying hole is sealed by a lower end valve, the liquid fertilizer is again injected in the hollow rod under the action of negative pressure, and the quantity and the depth of embedment of fertilization can be conveniently adjusted in the process of fertilization.

Description

Quick fertilizer injector

The utility model belongs to the agricultural fertilizer farm machinery.

The crops of existing field planting are generally used the method for the large tracts of land fertilising with irrigation water.In order to save fertilizer, improve fertilizer utilization ratio, Chinese patent 2236216 discloses a kind of quick fertilization device, portable handle during operation inserts soil, under the effect of power, inlet is opened automatically, liquid fertilizer flows into soil automatically, mentions handle, the spring self-return, inlet is closed automatically, be applicable to the individual plant crops are carried out fertilizer liquefaction deep placement, can be used with carrying over-shoulder sprayer simultaneously, be difficult for regulating but the weak point of its existence is the size of fertilizing amount and the weight of applying fertilizer.

The purpose of this utility model provides a kind of device that is suitable for the fertilising of individual plant crops, can regulate fertilization depth and fertilizing amount easily.

The utility model is achieved in that can insert rifle point 1 top of applying fertilizer in the soil has a plurality of holes 2 of flowing out solution, the top of rifle point is tubular structure, the lower end of hollow stem 10 is sleeved in the hollow pipe on rifle point 1 top, valve 3 in rifle point 1 hollow pipe withstands the lower end of hollow stem 10, extension spring 4 is housed in the hollow stem 10, and two ends are fixed with the valve 3 of lower end and the upper end of hollow stem 10 respectively.The inner ring of the top of rifle point 1 and piston-cylinder end socket 8 passes through thread connection, spring 7 is equipped with in the lower end of piston-cylinder end socket 8, cylinder sleeve 16 is actively set in the glass holder 9, the bottom of glass holder 9 is fixed by thread connection with cover cup 5 outside, regulates the stubborn embedded depth that closes depth-adjustment joint rifle point 1 of screw thread.The pod that glass holder 9 lower ends are equipped with piston set bar 6 and pass rifle point 1 is connected and fixed hollow stem 10, adjustable ring 14 also can be regulated in the upper end of cylinder sleeve 16 by thread bush, cylinder sleeve 16 is provided with the input and output gas that hole 15 is used to regulate the cylinder sleeve bottom, connecting rod 17 is contained in the upper end of cylinder sleeve 16, connecting rod 17 is transparent pipe, float 18 is equipped with in the inside, capacity in order to fertilizer-filling liquid in observing, connecting rod 17 is connected the sprayer back of the body bucket that fills solution, connecting rod 17 is withstood in boss upper surface in the cylinder sleeve 16, lower surface standing valve 13 is equipped with piston 12 between hollow stem 10 and cylinder sleeve 16, piston leather sheath 11 is fixed on the piston 12.

Comparing the beneficial effects of the utility model with background technology is can regulate the size of fertilizing amount and the embedded depth of fertilising easily in the fertilising process, and easy and simple to handle in addition, fertilising speed is very fast.

Fig. 1 is a structural representation of the present utility model.

Be described further below in conjunction with drawings and Examples.

Earlier fertilizer is fully dissolved by a certain percentage during operation, pour sprayer back of the body bucket into, make the sprayer delivery port connect transparent connecting rod 17, after solution enters the connecting rod 17 that float 18 is housed, with float 18 levitatings, can start working, at this moment leather sheath is in cylinder sleeve 16 bottom, solution backs down valve 13, flow in the cavity of cylinder sleeve 16, and be full of in the cavity of valve 13 and cylinder sleeve 16 compositions, when rifle point 1 is inserted in the soil, when firmly pressing down connecting rod 17, drive cylinder sleeve 16 and move downward, and glass holder 9 and hollow stem 10 move upward, piston 12 diminishes gradually with the epicoele volume that cylinder sleeve 16 is formed, because the sealing function of leather sheath 11, form certain pressure in the epicoele of cylinder sleeve 16, because this pressure forces valve 13 to be closed, valve 3 is up with hollow stem 10 simultaneously, leave rifle point 1 termination, fertilizer spraying hole 2 is exposed, when continuing to press down connecting rod 17, make the pressurized solution along the descending valve 3 that backs down of hollow stem 10 inner chambers, from fertilizer spraying hole 2 ejections, rich water infiltrates in the soil.Carrying out the aforesaid operations process simultaneously, piston 12 is up, and piston cylinder spiracle 15 is in air-breathing duty, has so just finished and has once annotated fertile process.Solution is forced out in hollow stem 10, and when connecting rod 17 no longer was stressed, piston 12 was subjected to the active force of spring 7 descending by hollow stem 10 and piston set bar 6, and cylinder sleeve 16 is subjected to acting force of the spring and up.At this moment spiracle 15 is in the exhaust work state, when piston 12 is descending, be negative pressure in cylinder sleeve epicoele and the hollow stem 10, and when descending when moving to cylinder sleeve 16 lower ends, solution is full of again in the cavity of cylinder sleeve 16 and valve 13 and hollow stem 10 compositions fast.At this moment, valve 3 cuts out by the elastic force effect of extension spring 4, and seals fertilizer spraying hole 2.If when connecting rod is subjected to downward active force once more, next periodic duty process of beginning fertilizer injector.

Regulate the screw thread between ring set 9 and the cup 5, can regulate the embedded depth of fertilizer injector, regulate the adjustable ring 14 of cylinder sleeve 16 upper ends, the solution quantity that can regulate each injection according to different crops.
