Description

Paddy field side deep fertilizing fertilizing amount adjusting device

Technical field

The invention belongs to agricultural machinery, relate generally to the operation part on the fertilizing equipment of paddy field.

Background technology

Plurality of advantages such as the outer groove wheel fertilizer applicator is to use the most general operation part of use in the chemical fertilizer operation at present in the floods and droughts field, and, service life simple in structure, cheap owing to it is long receive user's welcome.But; Along with development of science and technology; The raising of agriculture requirement, outer groove wheel fertilizer applicator fertilising degree of regulation problem relatively poor, that regulate inconvenience manifests day by day, can not satisfy and adapt to the requirement of precision agriculture; Especially in recent years execute at the paddy field chemical fertilizer and broadcast; In fertilizer apparatus, set up defeated fertile screw auger or the defeated mandatory structure of fertile spiral wire for overcoming and solve the problem of in fertilizer apparatus, making somebody a mere figurehead or even stop up the fertilizer delivering pipe road that causes because of chemical fertilizer moisture absorption deliquescence, having, adhering to prevent the subsides of chemical fertilizer in pipeline.The outer groove wheel fertilizer applicator can't supportingly use traditionally in this device, therefore provides a kind of fertilizing amount adjusting device of new construction extremely urgent.

Summary of the invention

The object of the invention is exactly the problem that exists to above-mentioned prior art; Actual needs in conjunction with the agricultural production operation; Design provides a kind of paddy field side deep fertilizing fertilizing amount adjusting device of new construction, the purpose that reach fertilizing amount degree of regulation height, operate simple and convenient, applicability is good.

The objective of the invention is to realize like this: on the housing centre, be provided with from top to bottom be interconnected go into fertile through hole and screwed hole; On the outside wall surface of the ringwise blade Connection Block of integral body and internal face, be respectively equipped with external screw thread and internal thread; Through the external screw thread on the blade Connection Block outside wall surface that the screwed hole that the blade Connection Block is fitted in housing is inner, hinge axis hole is arranged on the blade Connection Block upper surface, and the following side inserting of articulated axle is on adjacent vanes; Vane group is circularized assembly; The upper lateral part of articulated axle is inserted in the hinge axis hole of blade Connection Block, and the circular groups zoarium that blade is formed is fitted in blade Connection Block inside, and the slip limited post fits on the blade downside admittedly; The swivel becket that is provided with involute shape guide chute is fitted in the blade bottom; The inserting of slip limited post in involute shape guide chute, have externally threaded locking ring through with the screw-internal thread fit of blade Connection Block, locking ring is fitted on the blade Connection Block endoporus downside position; Be positioned at the swivel becket bottom, fit and swivel becket axial location in the blade Connection Block with the circular groups of blade composition; On the sidepiece of housing, offer the housing notch; On blade Connection Block sidewall, offer the Connection Block notch; It is outside that the housing notch is positioned at the Connection Block notch, and overlap each other, and the handle inserting is in housing notch and Connection Block notch; Handle inner end portion is connected on the swivel becket, so far constitutes paddy field side deep fertilizing fertilizing amount adjusting device.

The present invention adopts blade ring body fabricated structure; Realize the big or little variation of fertilising bore aperture; The completion fertilizing amount is regulated; Can be fitted in the water, dry land fertilization system of various structures and use, especially be fit to and the fertilization system supporting operation of forcing defeated fertile blade auger or the defeated fertile parts of spiral wire is installed, have that structural design is new reasonable, the fertilising precision is high, fertilizing amount is regulated the operation simple and convenient, reliable, the advantage of wide range of application of operation.
