Description
Technical field
The present invention relates to a kind of vegetable harvester tool, refer in particular to a kind of three leaf vegetables mechanical harvest devices.
Background technology
The market demand of China south characteristic vegetables three leaf vegetables constantly increases, cultivated area further enlarges, and south carries out the output-based contract responsibility system allocate land on the household base, and some field pieces are not suitable for the operation of motor driven type harvesting machinery because area is little, out-of-shape, poor flatness, can only manually gather in reaping hook, cause toothing shallow, be unfavorable for the diauxic growth of three leaf vegetables, big at manual work labour intensity, efficient is low, also is not fit to the harvest machinery of results three leaf vegetables on the market.
At present, some grass harvester harvesting principles are similar with three leaf vegetables harvest machineries on the market, but are not suitable for the harvesting of three leaf vegetables.One, can be divided into blade by its cutter sweep moves back and forth and disk gyration two classes; Disk revolution class reaping apparatus cuts broken crop easily when high-speed cutting, only be fit to the harvesting green crop, and reciprocating type reaping apparatus is because single action cutter motion frequency is low, and clamping stagnation stops up easily, is difficult to adapt to the cutting of flexible stem stalk; Two and some grass harvesters on the market adopt gasoline engines to drive entire mechanism running, one day needs the oil consumption expense is more than hundred yuan, gasoline engine oil proportioning difficult grasp, the particularly easy scuffing of cylinder bore of summer high temperature, the sticking stifled oil circuit of gasoline volatilization machine oil precipitation in the miscella, use up all at every turn and must carry out maintenance work, also have accessory costliness, energy consumption big, and three leaf vegetables are planted problems such as gasoline " run, drip, leak " contaminated environment in booth; Three, the height of present herbage harvesting device cutter can not be regulated, and is confined to level altitude, and to this ten seasons of annual growth of clover, cutting has certain limitation when weak back continued growth and highly more and more higher crop are cut; Four, general grass making machinery operating personnel is more.
The technical solution adopted for the present invention to solve the technical problems is: test according to three leaf vegetables mechanical characteristics, three leaf vegetables required drive when harvesting is little, adopt reciprocating type two moving cutter sweep, the harvesting fabric width is wide than disc type, can obtain to pluck preferably quality, cut weak concordantly, and can not produce the phenomenon of cutting broken crop; The transmission mechanism compactness, gathering unit is simple and easy, and cutter is reliability and durability; Power set adopt electromotor, green non-pollution, and running gear adopts artificial carrying out at present, puts aside motor-driven walking, to reduce price, connects with axle sleeve between reaping apparatus and running gear, and the axle sleeve of replaceable different length changes cutting-height.Adopt harvesting, collect the integrated number that reduces the operating personnel, alleviate operating personnel's working strength.
Summary of the invention
Purpose of the present invention is exactly the problem and shortage at existing technology and existence, design provides a kind of three leaf vegetables harvest machineries, the transmission mechanism compactness, high efficiency, facility flexibility are good, easy to operate, pollution-free, can improve the quality that three leaf vegetables regrow.
A kind of three leaf vegetables mechanical harvest devices, include dolly, it is characterized in that: be provided with header frame at the dolly front end, blower fan is installed on header frame, blower fan is provided with electromotor, the output of electromotor is as the driving shaft of blower fan, below header frame, be provided with reduction gear box, the output shaft while of electromotor is as the driving shaft of reduction gear box, reduction gear box is connected with slider-crank mechanism, reciprocating knife is installed on the slider-crank mechanism, deceleration of process reduction gear box and acquisition moment of torsion drive slider-crank mechanism makes reciprocating knife move back and forth, the resultant gear ratio i=4 of whole transmission device, and this gearratio just can be realized with the one-level deceleration transmission, the exhaust duct of blower fan is positioned at a side front upper place of reciprocating knife, and the air draft direction is the rear side of cutter and does not block three leaf vegetables with the last plane parallel and the exhaust duct of cutter.
Described reduction gear box is become by a pair of one-level driving gear set, and the output shaft of electromotor exports moment of torsion the pinion of reduction gear box to, the gear wheel engagement of pinion and reduction gear box, and gear wheel is connected with slider-crank mechanism.
Described slider-crank mechanism is made up of eccentric mechanism and two eccentric rollers, two eccentric rollers are installed on the eccentric mechanism, the axle center of two eccentric rollers and the axle center of eccentric mechanism are in alignment, to reduce and to eliminate the vibrations that the cutting moment of resistance causes, the gear wheel of reduction gear box is connected with eccentric mechanism.
Described reciprocating knife comprises that upper and lower two have the blade of cutter tooth and upper and lower two the square frame grooves that are connected with two blades respectively, and upper and lower two square frame grooves are connected by notch and two eccentric rollers respectively.
Described header frame connects by axle sleeve with dolly, and axle sleeve is by changing length to regulate harvesting height.
The collecting box that can dismantle at any time is housed on the described dolly, has effectively alleviated operator's labour intensity.
Three leaf vegetables grain headers of the present invention are simple in structure, the operating efficiency height, convenient, flexible, go for the booth three leaf vegetables operations of some southern little field pieces, owing to adopt motor driven, emission-free discharging during harvesting, can improve the quality that three leaf vegetables regrow,, compare with other cutter forms owing to adopt reciprocating knife, operating efficiency improves greatly, owing to adopt the slider-crank mechanism of eccentric roller and square frame slot type, the transmission mechanism compactness guarantees the good stressing conditions of cutter, prolong the service life of cutter, eccentric roller is contained in the square frame chute on the cutter head, makes square frame play slide block and does to make moving knife become simple harmonic motion like this in order to drive cutter, stable working, vibrate for a short time, mechanism is simple, and the space is taken up an area of less, mechanism's compactness, three leaf vegetables reaping machines of the suitable medium and small swath of front positioning type.
