Description
Technical field:
The invention belongs to agricultural machinery farming technique field, more particularly, to a kind of squash type ditching machine.
Background technology:
Ditch has relatively broad application in agricultural planting, engineering technology, and such as farmland water-saving irrigation opens rectangle groove laying certainly
Come waterpipe or cable, and plantation Rhizoma Dioscoreae etc., therefore the species of ditch, purposes, shape, size, structure are various, some furrow widths and
The shallow ditch having is narrow and deep, is such as too narrow to 10cm, as deep as 1.5m；Some ditches have the gradient, and some ditches do not have the gradient, and acclive ditch is general
At 30 ~ 60 degree, using the obvious inefficiency of hand excavation, in order to adapt to different application scenarios, now polytype and
The ditching machine of multiple use, has higher work efficiency.
In agricultural planting, primarily to improving field prevention waterlogging drought resistance, the guarantor for crops produces, increases production ditch,
There is very important effect, now with the ditching machine of multiple structural forms.Ditching machine product can be divided into chain ditcher, wheel disc
Formula ditching machine, rotary ditcher, ploughshare formula ditching machine.
One is to install and drag gimmal operation on large tractor.Large tractor is installed and drags gimmal
Carry out ditching operation, because tractor output speed is higher, mismatch with the slow-speed of revolution high torque of chain, easily cause chain to break
Split, and efficiency is low.
Two is machine chain ditcher.It is delivered in deceleration system by the four associated rotations by diesel engine in dynamical system
Head sprocket mounted thereto is driven, head sprocket drives the chain being engaged with to rotate after reduction box.Cutting tool installation manner on chain,
Under the driving of dynamical system, chain-driving cutter rotates plus translation, thus realizing ditching.Institute's digging groove depth is consistent, width
Uniformly and size adjustable, Mining Quality and efficiency are substantially increased.
Three is Wheel-type ditching machine.Dumped with the milling of rotation and drive the farmland construction machinery building irrigation and drainage irrigation canals and ditches for main working parts.
There are double-disk and two kinds of table roller formula by structural shape；Low speed then can be divided in the way of operation once to become ditch repeatedly to become with high speed
Ditch two types.Using low speed once become ditch and cut soil, the milling of throwing native functional separation is dumped structure, has higher production effect
Rate.It is to cut native knife equipped with several groups on the conical surface of a truncated cone disk and both sides card and throw native plate that milling is dumped.Disk plane
With the angle on ground, that is, the gradient of furrow bank be 40 °～60 °.During operation, milling is dumped by tractor motive power output shaft through drive system
Drive rotation, its outer rim linear velocity is about 7～15 meter per seconds.Cut the soil that native knife milling gets off to be dished out outside ditch by throwing native plate.Circle
Disc type ditching machine is that the rotation of electromotor is delivered on the disk being relatively large in diameter being provided with cutter, real by the rotation of disk
Now excavate.This device for disc structure is to slow down to realize by a series of band of Diesel Driven, chain, sprocket wheel, worm speed reducer etc.
The slow-speed of revolution, high pulling torque, thus driving turntable rotation to excavate, final assembly high cost, complex structure, parts are worse frequently, effect
Rate is low.
Four is a kind of ditching machine on big four-wheel tractor for the outstanding back of the body of large tractor mounted ditching machine, complete using rotary knife
Become trench digging.Traction power very little needed for rotary ditcher, the soil dished out can equably be sprinkling upon two surveys of ditch, need not repair.
Five is ploughshare formula ditching machine.Soil is cut directly into using turnplow cutter, advantage is that structure is simple, and productivity ratio is higher, single
The energy consumption of the position earthwork is less, turnplow soil is achieved certain be squeezed into ditch, but because turnplow action length is short, make ditch surface
Of poor quality.
The problem that several ditching machines are primarily present above is, is all to carry out milling or turning using single cutter to soil
(ploughshare formula ditching machine) has reached the purpose of trench digging, but does not have to make opened ditch reach due use standard and service life,
As ditch surface intensity is not enough, groove face extremely easily caves under rainwash, leads to the function of ditch to be lost；On the other hand, milling
Groove face after the effect of class cutter, between soil internal soil, gap is big, and the moisture on field is easy to ooze out, and is unfavorable for the guarantor of crops
Water requires, and particularly at the beginning of crop seeding, when crops do not grow, water conservation is had high demands.Solve above such
Problem, only adopts many kinds of measures, improves ditch surface intensity, improves groove face quality.In addition, existing ditching machine is advised mainly for one
The ditch of lattice size is designed, and limits the universality application of ditching machine.
Therefore, the demand for above-mentioned prior art is it is necessary to provide a kind of squash type ditching machine, to solve prior art
In problem.
