Abstract

The utility model relates to a direct press type fertilization machine. A hand pump is connected with the upper face of a fertilization machine gun head of a return stop valve arranged in an inner cavity, and liquid fertilizer is deeply fertilized into soil by the hand pump. Because of strong injection pressure of the hand pump, the clogging phenomenon and the null injection phenomenon are not easily generated; because of definite volume of a pump cylinder of the hand pump, piston travel is easily controlled to cause the rate of fertilization to be uniform. The utility model has the advantages of convenient operation, labor saving and rapidity.

Description

The direct press type fertilizer applicator

The utility model relates to a kind of liquid fertilizer deep applicator.

At present, the liquid fertilizer deep applicator that generally use in the rural area is used with sprayer, directly provides injection pressure by sprayer, controls fertilizing amount by sprayer rocking bar stroke.Like this, the one, because the insufficient pressure of sprayer often occurs blocking in the deep placement operation process and the empty phenomenon of annotating; The 2nd, when bearing sprayer, the rocking bar stroke is difficult to even control, makes the fertilizing amount inequality; The 3rd, on human body, labour intensity is big entirely for the application point of injection pressure; The 4th, one holds the sprayer rocking handle during fertilising, and one holds fertilizer applicator is inserted into crop root, as solid soil, very painstaking.

The purpose of this utility model is to remedy above-mentioned deficiency, provides a kind of and directly provides the direct press type fertilizer applicator of injection pressure by fertilizer applicator, makes fertilising evenly, and is easy to operate, laborsaving, rapid, and is difficult for producing and blocks and the empty phenomenon of annotating.

The utility model connects hand pump be achieved in that the fertilizer applicator rifle head that valve only is housed back in inner chamber above, by hand pump, with the even deep placement of liquid fertilizer in soil.

The utility model will be further described below in conjunction with accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

With reference to accompanying drawing: the rifle head by barral of a gun (10), rifle point (12), limit dark piece (11) to form, the inner chamber of barral of a gun (10) is equipped with back only valve, return ending valve is made up of plastic bead (8), spring (9), rubber base (7), only returning, valve is fixed in the inner chamber of barral of a gun (10) with fixed cover (6), the dark piece of adjustable limit (11) is housed on the rifle point (12), and the lower curtate of rifle point (12) has some injection orifices (13).Connect hand pump above the rifle head, hand pump is by handle (1), piston rod (2), piston (4), and pumping cylinder (5) is formed, and the middle part of pumping cylinder (5) is provided with a feed liquor and chews (14).In order to make operation more laborsaving, liquid back pipe (3) is set in the middle and upper part of pumping cylinder (5).

During use, the feed liquor of the fluid of liquid receiver (17) bottom being chewed (16) and hand pump with flexible pipe (15) is chewed (14) and is connected, and adjusts and limits dark piece (11).Liquid fertilizer is packed into behind the liquid receiver, bear liquid receiver, one holds the handgrip of pumping cylinder (5), one holds the handle (1) of piston rod, fertilizer applicator inserts in the soil, when piston (4) when moving up, the liquid fertilizer (18) of liquid receiver (17) lining enters in the pumping cylinder (5) by the negative pressure in the nature discrepancy in elevation (H) and the pumping cylinder (5), when depressing piston (4), liquid fertilizer in the pumping cylinder (5) is extruded pushes the valve that only returns barral of a gun (10) chamber in open, inject the ground earth from spray-hole (13) through rifle point (12), thereby finished deep placement work.

The utility model has following advantage:

1, because manually the injection pressure of pump is big, is difficult for producing and blocks and the empty phenomenon of annotating.

2, the volume of pumping cylinder is constant, and the stroke of piston is convenient to control, makes fertilising reach easily even.

3, the partial action point of injection pressure reduces labor intensity in soil.

4, with the hands operate fertilizer applicator, convenient, laborsaving, rapid.

Claims

1, a kind of direct press type fertilizer applicator, form by rifle head and hand pump, the rifle head is by barral of a gun (10), rifle point (12), limit dark piece (11) to form, the inner chamber of barral of a gun (10) is equipped with back only valve, return and end valve by plastic bead (8), spring (9), rubber base (7) is formed, only returning, valve is fixed in the inner chamber of barral of a gun (10) with fixed cover (6), the dark piece of adjustable limit (11) is housed on the rifle point (12), the lower curtate of rifle point (12) has some injection orifices (13), it is characterized in that connecting hand pump above the rifle head, hand pump is by handle (1), piston rod (2), piston (4), pumping cylinder (5) is formed, and the middle part of pumping cylinder (5) is provided with a feed liquor and chews (14).

2, direct press type fertilizer applicator according to claim 1 is characterized in that the middle and upper part of the pumping cylinder (5) of hand pump is provided with liquid back pipe (3).
