Abstract
Pressing liquid fertilizer fertilising pin belongs to agricultural machinery, pressing fertilizer pipe, tube connector and valve seat concentric be fitted in housing chamber from top to bottom successively, pressing fertile pipe bottom and tube connector upper end are connected, valve seat bottom is connected with the syringe needle with fertilizer hole, valve seat is packed in housing chamber, compression spring is sleeved on tube connector outside portion, compression spring upper, lower end is managed with pressing fertilizer respectively, valve seat contact coordinates, tube connector bottom is fixedly mounted with the spool with defeated fertile hole, spool is positioned at valve support chamber, with valve seat in contacting close fit or the unlatching that disengages coordinates, on the downside of tube connector on outside, position suit sealing ring between valve seat endoporus wall, what this pin adopted pressed by external force type of drive to realize liquid chemical fertilizer applies operation, novel structure, rationally, simple, manufacture process technology difficulty low, low production cost, use reliable.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of pressing liquid fertilizer fertilising operating assembly.
Background technology
Liquid chemical fertilizer fertilising operation is a kind of chemical fertilizer application new technology starting in recent years to apply, compared with traditional solid-state chemical fertilizer application, the plurality of advantages such as the liquid fertilizer processing had because of it is cheap, chemical fertilizer effective rate of utilization is high, cost is used in reduction, environmental pollution is light, the concern that research causes people is used in liquid fertilizer mechanization.Use needs for meeting and adapting to liquid chemical fertilizer machinery, applicant have developed several with the Stress control of liquid chemical fertilizer fertilising pin closure or openness, completes the fertilizer spraying needle of fertilising, tentatively achieves the mechanized application operation of liquid chemical fertilizer.But, the fertilizer system complex structure of this class formation fertilizer spraying needle, and fertilizer spraying needle requirement on machining accuracy is high, and manufacturing technology difficulty is large.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing, researches and develops a kind of pressing liquid fertilizer fertilising pin, reaches the object simplifying structure, reduce liquid fertilizer fertilising pin mechanical processing difficulty and manufacturing cost.
The object of the invention to be achieved in that in housing chamber from top to bottom the equipped pressing fertilizer pipe of concentric successively, tube connector and valve seat, bottom and the described tube connector upper end of described pressing fertile pipe are connected, described valve seat bottom is connected with the syringe needle being provided with fertilizer hole, is packed in by valve seat in housing chamber; Compression spring is sleeved on tube connector outside portion, the top and bottom of described compression spring coordinate with pressing fertile pipe lower end and valve seat upper-end contact respectively, described tube connector bottom is connected the spool installed with defeated fertile hole, described spool is positioned at valve support chamber, and with valve seat in contacting close fit or the unlatching that disengages coordinates; On the downside of described tube connector, on outside, between valve seat endoporus wall, position is set with sealing ring, so far forms pressing liquid fertilizer fertilising pin.
The invention adopts pressed by external force type of drive to realize applying of liquid chemical fertilizer and applies control with stopping, change and utilize liquid chemical fertilizer pressure itself to control applying of liquid chemical fertilizer to apply control principle with stopping, having novel and reasonable structure, simple, manufacture that process technology difficulty is low, low production cost, service-strong feature.
Accompanying drawing explanation
Fig. 1 is pressing liquid fertilizer fertilising pin general structure schematic diagram.
In figure, piece number illustrates:
1, pressing fertilizer pipe, 2, tube connector, 3, spool, 4, valve seat, 5, sealing ring, 6, compression spring, 7, housing, 8, syringe needle, 9, fertilizer hole, 10, defeated fertile hole.
Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.A kind of pressing liquid fertilizer fertilising pin, the equipped pressing fertile pipe 1 of concentric, tube connector 2 and valve seat 4 successively from top to bottom in housing 7 chamber, bottom and described tube connector 2 upper end of described pressing fertile pipe 1 are connected, described valve seat 4 bottom is connected with the syringe needle 8 being provided with fertilizer hole 9, is packed in by valve seat 4 in housing 7 chamber; Compression spring 6 is sleeved on tube connector 2 outside portion, the top and bottom of described compression spring 6 coordinate with pressing fertile pipe 1 lower end and valve seat 4 upper-end contact respectively, described tube connector 2 bottom is connected the spool 3 installed with defeated fertile hole 10, described spool 3 is positioned at valve seat 4 chamber, and with valve seat 4 in contacting close fit or the unlatching that disengages coordinates; On the downside of described tube connector 2, on outside, between valve seat 4 endoporus wall, position is set with sealing ring 5.
During operation, liquid chemical fertilizer is filled with at pressing fertile pipe 1, tube connector 2 and spool 3 inner from liquid fertilizer case, external force presses pressing fertile pipe 2 downwards and moves downwards, driving through tube connector 2 makes core valve 3 move downward in valve seat 4, defeated fertile hole 10 is departed from and the close fit of valve seat 4, and liquid chemical fertilizer applies in the soil cavities outputed by syringe needle 8 through defeated fertile hole 10, fertilizer hole 9.When external force disappears, under compression spring 6 acts on, the pressing fertile pipe 1 moved upward pulls spool 3 to be upwards synchronized with the movement by tube connector 2, gets back to initial position, and the defeated fertile hole 10 on spool 3 is closed by valve seat 4, stops fertilising operation.Iterative cycles successively.
