Description
Technical field:
The utility model relates to a kind of agricultural machinery, particularly relates to a kind of coaxial rotary cultivator realizing deep and extensive cultivation and shallow and fine crushing.
Technical background:
Rotovator is to finish cultivation machinery cultivated, the rake operation with tractor.Because of its have the hack ability strong, plough characteristics such as the face of land, back is smooth, and obtained using widely.Present rotovator is divided into horizontal shaft type and rotovator vertical shaft type two classes by the configuration mode of its rotary ploughing cutter shaft.The horizontal shaft type rotovator has stronger hack ability, and one-stop operation can make soil in small, broken bits, and the clay fertilizer blending is even, and ground is smooth, reaches the rotovator requirement that plant in nonirrigated farmland sowing or paddy field, helps striving for farming season, improves work efficiency, and can make full use of the power of tractor.But the covering power to stubble, weeds is relatively poor, more shallow (12～16 centimetres of the dry farmings of tilling depth; Water is ploughed 14～18 centimetres), energy consumption is bigger.Be mainly used in paddy field and vegetable field, also be used for the orchard intertillage.The tilling depth of heavy horizontal shaft type rotovator can reach 20～25 centimetres, is used for opening up wasteland the farming on shrub ground, marshland and ground, farmland running to weeds more.Workpiece comprises the rotary tillage rotor and cuts native blade by some handles that the bull helical evenly disposes that by actuator drives, normal revolution is 190～280 rev/mins by tractor motive power output shaft.The direction of rotation of rotor is consistent with the direction that tractor wheels is rotated usually.Cut native blade and cut soil layer after by forward direction, and soil block is thrown on case and the planker to the back upper place, make it further fragmentation.When rotor was cut soil and thrown soil, soil helped to promote unit to the reaction force of rotor and advances, thereby required tractive force is very little during the horizontal rotary tiller operation, sometimes even can promote unit by rotor and advance.Cut native blade and can be divided into scalpriform cutter, tulwar, right angle cutter and curved knife.Scalpriform cutter front end is narrower, and the ability of burying is preferably arranged, and energy consumption is little, but easily twines grass, is used for few vegetable garden of weeds and garden more.The curved cutting edge of tulwar has the sliding cutting effect, easily cuts off grass roots and straw winding is suitable for the paddy field farming.The right angle cutter has vertical and horizontal cutting blade, the blade broad, and good rigidly make easily, but penetration performance is relatively poor.The intensity of curved knife is big, good rigidly, and sliding cutting is made good use of, and is generally used on the heavy rotovator.With tractor below 15 kilowatts the time, the general employing directly connects, without the universal joint transmission; With more than 15 kilowatts during tractor, then adopt trifilar suspension formula, universal joint transmission; The general employing of heavy rotovator is towed.Tilling depth is by planker or gauge wheel control and adjusting.Planker is located at the back of rotor, held concurrently hack and smooth effect; Gauge wheel then is located at the place ahead of rotor.The configuration mode of rotor afterbody transmission device has two kinds of side transmission and central transmissions.The side transmission is used for the less offset ratory cultivator of working width more.Central authorities' transmission is used for the bigger rotovator of working width, and the symmetry of machine is good, and machine stress is even; But an area below the transmission case rotovator does not reach to form and balks owing to cutting native blade, need establish in addition and eliminate the device of balking.Vertical shaft type rotovator workpiece is the rotary cultivator attachment that 2～3 scroll cutting knifes are housed.Rotary cultivator attachment rotates around vertical shaft during operation, and cutting knife shreds soil.Be applicable to that paddy field water either is cultivated, stronger hack is arranged, play the slurry effect, but covering performance be poor.Use more in Japan.For strengthening the farming effect of rotovator, on some national rotovator, install various attachment devices additional.As articulating spike-tooth harrow in the rotovator back, install break shovel additional to add deep plough level etc. to strengthen the hack effect.
And at present, the rotary tillage mode of rotovator has three kinds:
First kind is by host header (tractor), driving back rotary tillage break bar as preceding power ploughs, the advantage of this arable land mode is that the front has running gear, can control the speed of travel, prevent that break bar from becoming road wheel, make break bar effectively drive colter and be rotated, soil is dug to greatest extent.Its shortcoming is: the earth of being digged becomes bulk not of uniform size, and this big block soil just can carry out proportion of crop planting after also needing manually once more the top layer large clod to be broken into uniform fritter shape when plantation.
Second kind is on first kind basis, on the deep ploughing blade shaft, dark blade and shallow blade are installed simultaneously, this break bar shortened cutting blade in the hack process has certain hack effect, but because long and short blade is all done synchronous rotation on same axle, the linear speed difference of its long and short blade is bigger, and the top layer soil block still can not effectively become clods breaking the required soil fineness of different plants.More than two kinds of arable land modes all need big power to control, also be not suitable in the paddy field, patch and hillside fields farming.
The third is small-sized rotovator, and the advantage of this rotovator is can be in patch and hillside fields farming.Its shortcoming is that the break bar of this machine is that to plough cutter be again road wheel simultaneously when ploughing, this structure when soil softer, particularly when underwater cultivation break bar will the original place rotation and can not walking, when face of land soil is hard, Rotary tillage blade can not effectively screw in the soil and form walking fast, thereby soil can not effectively be stirred, make entire machine beat significantly occur, the people is difficult to control, the soil of being up to not only is uneven, and become big block, and it is poor to plough dark uniformity, and such soil needs can plant after the secondary hack is smooth.In left and right sides soil soft or hard not for the moment, span diverse before and after left side break bar and the right break bar will occur is difficult to control.
