Abstract
A potato vine cutting machine comprises a machine frame, a walking device, a gearbox, a transmission device and knife rollers. The walking device is arranged below the machine frame, the gearbox, the transmission device and the knife rollers are sequentially arranged on the machine frame from front to back, and the gearbox is connected with the knife rollers through the transmission device. The walking device comprises front walking wheels and rear walking wheels, the front walking wheels are symmetrically distributed at the front end of the machine frame, and the rear walking wheels are distributed at the rear end of the machine frame. Furrow vine picking devices are arranged on the front walking wheels and comprise fixing cell discs and vine picking elastic teeth arranged on the fixing cell discs, and the fixing cell discs are connected with the front walking wheels through driving shafts. Vine picking elastic tooth devices pick vine stems at the bottoms of furrows and throw the vine stems backwards, and then the knife rollers rotate at high-speed to break the vine stems and the vine stems are laterally sprayed and conveyed to the left side of the vine cutting machine through air pressure and steady air flow generated due to high-speed rotation of the double rollers. According to the potato vine cutting machine, potato vine stems can be effectively cleaned away and walking resistance in the follow-up harvesting process is reduced.
Description
Technical field
The invention belongs to agricultural machinery technological field, be specifically related to one and kill seedling machine, relate in particular to a kind of ditch cleaning lateral spray type potato seedling killing machine.
Background technology
Killing seedling is important step before tuber crops results.Facts have proved, kill seedling and not only can reduce the resistance that too much potato seedling causes reaping machine, more can greatly improve efficiency of crop, cost-saving.Before receiving, kill this link of seedling, the resistance of reaping machine is reduced, travel speed is accelerated, and fault rate reduces, and the resistance of the potato seedling separator of reaping machine inside also can reduce greatly, and potato seedling disintegrate-quality significantly improves.There are following two problems in existing potato seedling killing machine: (1) will potato haulm stalk cut off or chopping after paving be sprinkled upon earth's surface, so just cause crop stem winding component of machine, potato tubers in the mechanical harvest link in later stage to separate time-consuming problem with stem stalk; (2) present potato planting agriculture requirement is ridging, and general kill seedling machine and can not well work in this kind of plot.Therefore, design a kind of integrate kill seedling, receive seedling function and can adapt to the potato seedling killing machine of different cropping patterns significant.
China's potato class growing area mostly is medium and small plot, particularly hilly and mountainous land, and plot is less, and the external ripe large-scale seedling machine that kills is difficult to application.And the domestic small-sized seedling machine that kills is of less types, and shed the mode on ridge after all seedling is killed in employing, therefore seedling bar still causes certain drag effects to reaping machine.In addition, present potato planting agriculture requirement is ridging, and therefore the seedling bar in furrow is difficult to cleaning, causes too much unclean problem of the residual seedling bar of furrow.
Summary of the invention
The problem existing in order to solve existing potato seedling killing machine, the invention provides a kind of ditch cleaning lateral spray type potato seedling killing machine.After described ditch cleaning lateral spray type potato seedling killing machine has solved furrow residual lodging seedling stalk and killed seedling, seedling stalk is sprayed on the problem that on ridge, reaping machine results is caused larger resistance.
Technical scheme of the present invention: kill seedling machine, comprise frame, running gear, gearbox, transmission device and rotor, running gear is arranged on the below of frame, gearbox, transmission device and rotor are successively set in frame from front to back, gearbox is connected with rotor by transmission device, and the both sides of frame are provided with side plate.Running gear comprises front walking wheel and rear walking wheel, and the quantity of front walking wheel and rear walking wheel is two, and two front walking wheels are symmetrically distributed in the front end of frame, and two rear walking wheels are symmetrically distributed in the rear end of frame.Front walking wheel (2) is provided with furrow and chooses seedlings device, furrow is chosen seedlings device and is comprised fixed grating dish and be arranged on and choose seedling elastic claw on fixed grating dish, described fixed grating dish is connected with front walking wheel by driving shaft, described length of choosing seedling elastic claw is 100-120mm, the described diameter of choosing seedling elastic claw is 3-5mm, described material of choosing seedling elastic claw is that phosphorus content is the carbon constructional quality steel of 0.6-0.9%, comprises 65Mn spring steel, 70Mn spring steel and 85Mn spring steel.The described coefficient of rigidity 71000-77000MPa that chooses seedling elastic claw, tensile modulus of elasticity 190000-210000MPa; Tensile strength: 800～1000Mpa; Yield strength: 500～700Mpa; Tensile stretch: 14～22.5%; The contraction percentage of area: be not more than 10%; Hardness: hot rolling ,≤302HB; Hot rolling+thermal treatment ,≤321HB.
The rear that furrow is chosen seedlings device is provided with rotor I and rotor II; Rotor I is arranged on the side near power transmission shaft, and described rotor II is arranged on the side near rear walking wheel.Described rotor comprises that roll shaft and double helix are arranged in the blade on roll shaft, and described blade passes through tool rest mounted in pairs on roll shaft; Described insert tip and the distance of choosing between seedling elastic claw end are 0-5cm.Blade adopts bifilar helix arrangement not only to make rotor running more stable, and the directed steady air flow producing also plays an important role to the discharge of broken seedling stalk.Described blade is the arc blade that puts the first edge on a knife or a pair of scissors, and comprises arc tulwar on ridge, slope, ridge arc tulwar and furrow arc tulwar, and on ridge, arc tulwar, slope, ridge arc tulwar and furrow arc tulwar are evenly arranged alternately on rotor.On ridge, arc tulwar is short sword, and its length is 12-14cm, for the treatment of the seedling bar on ridge; The length of furrow arc tulwar is mated with the degree of depth of furrow, and its length is 23-25cm, for the treatment of the seedling bar of furrow; Slope, described ridge arc tulwar length is slightly longer than furrow arc tulwar, and its length is 18-20cm, and the point of a knife of slope, described ridge arc tulwar tilts, for the treatment of the seedling bar on slope, ridge.
