Description
Technical field
This patent relates to a kind of soil and ploughs whole farm machinery, particularly a kind of less plot and Hills and Handheld small-sized crawler chain type deep ploughing machine for soil deep ploughing of being suitable for.
Background technology
Arable land is important measures of agricultural production, and object is as the sowing of crop is germinateed, growing provides good soil environment.Plough wash with watercolours soil, improve soil structure, eliminate weeds and damage by disease and insect, for crop growth is created good condition.Utilize machinery deep ploughing, can make loose soft, the well-formed of topsoil, active soil stratum thick, smooth fertile, solid phase, liquid phase, gas phase ratio are coordinated mutually, the requirement that adaptation grows.But no matter be that old-fashioned farming or machinery are ploughed at present, ubiquity is ploughed shallow, if things go on like this, mellow soil layer thickness reduces, and tillage pan thickness increases, the requirement to soil while being difficult to meet crop growthing development, and grain yield will be affected.Deep ploughing can be thickeied plow layer, improves soil water storage soil moisture conservation, promotes soil-ripening, accelerates decomposition and the accumulation of nutrient, for plant growth provides deep topsoil, is one of major measure further improving output.Deep ploughing is heavy load operation, and the general supporting relevant farm machinery of large and middle tractor that adopt carry out at present, and this mode is also not suitable for less plot and Hills use.The general tillage method that adopts rotary tillage of the more existing machinery of the deep ploughing for less plot and Hills carries out ploughing work, not only mechanical output consumption is large for this rotary tillage process mode, and tilling depth is very shallow, the meeting of rotary tillage simultaneously produces certain destruction to the physicochemical property of soil.The rotary tillage workpiece that it is mechanical that these are deep ploughed is placed on the layout of the mechanical rear end of deep ploughing also can bring certain potential safety hazard to the mechanical tractor driver of operation deep ploughing.
Summary of the invention
This invents the soil of deep ploughing, and thickeies topsoil, improves the water of soil, the hot situation of gas; Vegetable soil, improves Soil nutritional condition, improves the effective fertility of soil; Set up good soil structure, improve crop yield; Eliminate weeds, preventing and kill off damage by disease and insect is object, and research and development have designed a less plot and Hills and the farm machinery, particularly a kind of Miniature walking crawler chain type deep ploughing machine that does not adopt rotary tillage process mode for soil deep ploughing of being applicable to.
The technical scheme that this patent adopts is: Miniature walking crawler chain type deep ploughing machine, comprises chain type deep ploughing operation part and crawler type traveling machine two parts.Chain type deep ploughing operation part comprises: chain and sprocket wheel, be fixed on the cultivated pawl assembly on chain, and adjust motor, driving pulley and tilling depth regulate screw mandrel etc.Crawler type traveling machine comprises: crawler unit, engine, crawler driving whell, belt and belt pulley, frame and link, handrail etc.On integral layout, chain type deep ploughing operation part is connected with crawler running machinery by link and is fixed in the rectangular frame being surrounded by the frame of two crawler units and engine and crawler running machinery.This installation form has not only been guaranteed the tractor driver's who uses this deep ploughing machine job safety, and has simplified the structure of crawler type deep ploughing machine.
Engine outputs power to the crawler driving whell of crawler belt deep ploughing machine on the one hand by belt transmission, thereby drives crawler unit; Output power on the other hand to chain type deep ploughing operation part, drive the sprocket wheel coaxial with driving pulley, plough the motion of pawl assembly thereby drive.Plough the movement locus operation of pawl assembly along chain, plough the movement locus of the movement locus profiling of pawl in whole cultivating procedure when with hand plane soil, this forms of motion can reduce the power consumption of crawler belt deep ploughing machine, optimizes the service behaviour of crawler belt deep ploughing machine.The cultivated pawl of design is with certain radian, can be with good penetrating angle incision soil, and the cultivated pawl of adjacent two cultivated pawl assemblies is staggered, be conducive to like this shock and vibration that bring while reducing the work of crawler chain type deep ploughing machine, deep ploughing machine is operated steadily in the course of the work.
Utilize crawler belt as running gear, can make crawler chain type deep ploughing machine have good landform adaptive capacity, and there is good skid resistance.After crawler chain type deep ploughing machine is started working, crawler belt advances along the circuit requiring, the operation part of chain type deep ploughing simultaneously is also started working, sprocket wheel drives chain constantly to rotate, the cultivated pawl assembly that is fixed on chain top is worked continuously, constantly soil is excavated to farming, between link and chain type deep ploughing operation part, tilling depth is installed and regulates screw mandrel, and utilize adjustment motor to carry out Synchronization Control.In the crawler chain type deep ploughing machine course of work, the tilling depth of adjusting driven by motor both sides regulates screw mandrel to rotate simultaneously, chain type deep ploughing operation part is applied to downward active force, because the front end of chain type deep ploughing operation part is fixed on link, tilth is strengthened the downward-sloping rotation in its rear end gradually until the tilling depth requiring.
The technical scheme key of this patent is: 1. both sides tilling depth regulates the Synchronization Control of screw mandrel.If the tilling depth on both sides regulates screw mandrel synchronously not advance, can cause chain type deep ploughing operation part both sides unbalance stress and produce additional torque making crawler chain type deep ploughing machine job insecurity, when serious, can cause both sides support connecting frame distortion impaired, crawler chain type deep ploughing machine cisco unity malfunction.The scheme of solution is that employing is adjusted motor and driven the tilling depth on both sides to regulate screw mandrel, can accurately control so the synchronous rotation of both sides tilling depth adjusting screw mandrel.2. the pace of Miniature walking crawler chain type deep ploughing machine crawler unit and the velocity of rotation of chain and tilling depth regulate pressing down governing speed and will keeping coupling of screw mandrel.In the course of the work, crawler chain type deep ploughing machine constantly to overtake, plough pawl assembly on one side along with crawler chain type deep ploughing machine travels forward, on one side along with chain rotates, also under tilling depth regulates the effect of screw mandrel, move down, so if three's movement velocity do not mate and will cause crawler chain type deep ploughing machine operating efficiency to reduce being the slow or work quality of crawler chain type deep ploughing machine operating rate to decline not reaching the work tilling depth of requirement.The scheme solving is, show that by analytical calculation then movement relation between three select suitable engine and belt pulley to make the speed between three keep coupling.
The beneficial effect of this patent is, solved the problem of less plot and the deep ploughing of Hills soil, solved the existing rotary tilling-type excessive problem with spoiled soil physicochemical property of the tillage machinery power that causes of ploughing.And its rational layout has improved safety when tractor driver operates greatly.
