Description

The multi-functional mulberry tree grain header that harvesting height is adjustable

Technical field

The invention belongs to grain header field, be specifically related to the adjustable multi-functional mulberry tree grain header of harvesting height.

Background technology

At present, because mulberry tree has multi-harvest, repeatedly growth and the each harvesting height of mulberry tree can not identical characteristics, existing grain header can not directly gather in mulberry tree, because existing grain header greatly can not multi-harvest to the injury of crop remainder (root and a small amount of stem), and can not all need to regulate harvesting height than the characteristic of the high 4-5 of height centimetre of harvesting last time according to the height of the each harvesting of mulberry tree, the growing environment of mulberry tree is widely different, for being grown at the foot of the hill, the mulberry tree of multi obstacles environment on hillside, need extremely easy reaping apparatus to gather in, current mulberry tree mainly relies on artificial use reaping hook or lopping shears gathers in, exist harvesting efficiency extremely low, the shortcoming that labour intensity is large.

Summary of the invention

For the deficiencies in the prior art part, the special adjustable multi-functional mulberry tree grain header of harvesting height that proposes of the present invention, it can not only address the deficiencies of the prior art, and also has other many useful effects.

The multi-functional mulberry tree grain header that harvesting height is adjustable, formed by vehicle frame, adjusting height devices, lathe, transmission device, reaping apparatus, gasoline engine, pressure pump, spray lance and water tank, it is characterized in that: regulate height devices bottom to fix with vehicle frame, top and lathe are fixed, make lathe up-down adjustment by its handwheel, gasoline engine is fixed on vehicle frame, power output drives the knife section of reaping apparatus to move back and forth by transmission device, conversion output apparatus transmission object, makes pressure pump work that the water of water tank is extracted to pressurization.

Above-mentioned vehicle frame is the portable structure of single wheel, and wheel is positioned at vehicle frame front end, has two bracing frames at hand steered place.

Above-mentioned adjusting height devices is made up of upper plate, base plate, support arm, screw rod, screw pair connector, upper plate is connected by four symmetrical support bars with base plate, two support bars of homonymy connect by screw pair connector, screw rod connects support arm by screw pair connector, rotary screw makes the reciprocal relative motion of connector, and connector drives support arm to make upper plate vertical up-or-down movement.

Above-mentioned gasoline engine outputting power is delivered to the toggle that is fixed on lathe front end by Bowden cable, crank rotation makes connecting rod drive the knife section of reaping apparatus to move back and forth; Its outputting power makes the crank rotation of pressure pump by conversion flexible axle output connector, the liquid that pressure pump extracts in pressurised water tank sprays fog-like liquid by spray lance.

The course of work of the present invention is:

A, startup petrol engine, the crank that petrol engine provides power to arrive toggle by soft axle transmission, moves back and forth crank fast rotational drivening rod, constantly moves back and forth thereby make to gather in knife section, realizes harvesting function.

B, user make jack upper substrate upper and lower translation by the handwheel of rotation scissor-like jack by screw pair transmission, thereby make grain header lathe height change, and realize the harvesting of differing heights.

C, when the connector of changing flexible axle end makes to the power intake of pressure pump, pressure pump rotary work extracts pressurization the agricultural chemicals mixed liquor setting in advance in the water tank on lathe, is completed and is sprayed medicine function by spray lance.

Beneficial effect of the present invention is: can replace manpower to gather in mulberry tree, improve mulberry tree harvesting efficiency and reduce the destruction to mulberry tree, shorten the mulberry tree management cycle, simple in structure, facilitate the mulberry tree harvesting of various landform, simple to operate, there is very strong flexibility, adjustable differing heights, adapt to the different harvestings that require, harvesting object is wide, so can gather in row plantation bar class crops, collocation water tank can carry out spray cultivation operation, convenient multi-purpose.

Due to above-mentioned beneficial effect, the present invention is widely used in mulberry tree harvesting apparatus.
