Description

The automatic harvesting apparatus of ginger

Technical field

The utility model crop-harvesting mechanism, is specially the automatic harvesting apparatus of a kind of ginger.

Background technology

Ginger is not only important food seasoning, also has higher medical value, now has in hundreds of kind pharmaceutical formulation all containing ginger or its extract.

Ginger cultivation has a long history in China, and planting range is extensive.In recent years, along with the continuous expansion of ginger cultivation scale, harvesting approach has faced new test.At present, the results of China's ginger generally adopt manual work mode, because of ginger be generally positioned at underground darker, for preventing that ginger stem tuber from, by sliding trackle or damage, just need to deep-cut.Therefore manually receive ginger and have the problems such as labour intensity is large, time-consuming, production efficiency is low.

There is multiple ginger harvest machine for this reason.But current existing ginger harvest machine mostly can only complete and loosen the soil and lift seedlings, also need artificial cooperation to excise Jiang Miao, be partitioned into ginger stem tuber, and clear up the native mud on it.

Design that a to integrate the automatic harvesting apparatus of the ginger that loosens the soil, cuts apart imperative for this reason.

Utility model content

Technical problem to be solved in the utility model is: comprise loosen the soil, lift seedlings and cutting part in the automatic harvesting apparatus of ginger of one, easy to operate, and efficiency of crop is high.

The automatic harvesting apparatus of ginger of the utility model design, comprise frame, drive part, the part of loosening the soil, drive part comprises base plate, front-wheel, trailing wheel and drive motors, drive motors is installed on base plate, front axle and hind axle are rotatably installed on the forward and backward of base plate bottom, and front axle and hind axle fixedly mount respectively two front-wheels and two trailing wheels.

Frame is the frame structure that comprises underframe, upper frame, and 2 foundation chord positions are in this device longitudinal centre line both sides, and two foundation framves are fixedly connected with 2 upper frames of top through bogie side frame, and the plane that two upper frames form is frame face.Jointed shaft connects the middle part of 2 foundation framves rotationally, and jointed shaft two ends are arranged on the hinged axle bed on base plate.Jointed shaft is parallel with base plate, vertical with this device longitudinal centre line.In jointed shaft front, crossbearer is fixedly connected with 2 foundation framves, and crossbearer is parallel with jointed shaft.

On base plate, fixedly mount motor cabinet, hinged lifting motor on it, upward, through shaft coupling connection wire rod, the center line of screw mandrel overlaps with the output shaft center line of lifting motor the output shaft of lifting motor.On screw mandrel, have with it the screw coordinating, screw is fixed on elevating lever, and elevating lever is parallel with crossbearer, and 2 articulated jibs and elevating lever two ends that crossbearer is fixed are hinged.

In the time of the forward and reverse rotation of lifting motor, screw rises, declines at screw mandrel, drives frame to swing up and down take jointed shaft as axle, and lifting motor also swings on motor cabinet simultaneously, thus swing when frame is swung up and down.

The part of loosening the soil comprises forearm and break shovel, and frame front end is fixed in forearm upper end, and break shovel is fixed in forearm lower end, and break shovel is stretched the front lower place at base plate.The longitudinal centre line of forearm and break shovel overlaps with the longitudinal centre line of this device.In the time that this device advances, screw drives frame front to swing up and down, and forearm and break shovel, in the proal while, move up and down, the ground that this device of shovel pine is advanced.Control the opening and closing time of lifting motor, can control the amplitude that screw moves up and down, control the degree of depth that break shovel loosens the soil.

This device part that lifts seedlings in addition, the part that lifts seedlings comprises sprocket wheel and chain.Forward and backward each 2 sprocket shafts of fixing of upper frame of this device center line both sides, it is drive sprocket that each side has a sprocket wheel to be rotatably installed on sprocket shaft, respectively on other sprocket shaft fix a sprocket wheel, for by movable sprocket, sprocket shaft is vertical with frame face, each sprocket wheel is in the same plane.4 summits that the center of 4 sprocket wheels of every side is isosceles trapezoid, this isosceles trapezoid top margin is less than base.Each side has 1 chain ring around 4 sprocket wheels, and two chains in trapezoidal top margin are parallel near this device center line.

Power motor is arranged on frame bottom, and power motor drives the sprocket shaft of the drive sprocket that connects every side through transmission mechanism, drives this sprocket shaft to rotate, and drive sprocket drives chain walking, and chain-driving is respectively rotated on its axle by movable sprocket.The chain of the trapezoidal top edge of chain is all for by advancing after forward direction, and both sides chain is respectively around 4 sprocket wheels circulation walkings of this side.

The cutting part of this device comprises shearing knife, pull bar, carriage release lever, crank, connecting rod and worm and wormwheel, 2 shearing knife all have blade and handle of a knife, blade and handle of a knife be in 90 °～hexagonal angle, scissors hinge is vertical with frame face, be fixed on frame, and the center line of scissors hinge and the longitudinal centre line of this device intersect vertically.The blade of the blade of 2 shearing knife relatively, blade and cutter handle combining part be stacked and be articulated with scissors hinge.The hinged 2 identical pull bars of handle of a knife tail end, 2 pull bar tail ends and carriage release lever front end are hinged, carriage release lever tail end articulated linkage one end, affixed crank on worm-wheel shaft, crank and the connecting rod other end are hinged.Worm screw is rotatably installed on frame, worm gear and worm engaging.Power motor is connected with worm drive through transmission mechanism, drives worm screw to rotate.Worm gear drives crank to rotate, and connecting rod pulls carriage release lever to move forward and backward, and carriage release lever front end pulls pull bar tail end, thereby makes the opening and closing of shearing knife blade, cutting.Shearing knife is positioned at the below of the trapezoidal top margin of the part chain rear section that lifts seedlings.

This device sieves native part in addition, and it comprises that soil sieves, sieves native rocking bar, sieve soil axle, sieves native connecting rod and sieve soil crank.Soil sieve is fixedly mounted between 2 native rocking bars of sieve, 2 sieves native rocking bar upper end and frames are hinged, and lower end, with to sieve native connecting rod one end hinged, sieved native axle level and is rotatably installed on frame, sieve the native crank of native axle two ends fixed installation sieve, sieve the other end of the native connecting rod of the hinged sieve of native crank.Power motor drives and is connected through transmission mechanism and the native axle of sieve, drives the native axle of sieve to rotate, thus through sieve on native crank, connecting rod, draw or under push away sieve native rocking bar lower end, make to sieve the native rocking bar band sieve of breaking ground and shake up and down.Soil sieve is positioned at blade below, the base plate top of shearing knife opening and closing.It is upper that the ginger piece that shearing knife is cut drops on soil sieve, and the shake up and down of soil sieve, comes off the earth on ginger piece, falls from soil sieve.

Power motor connects the power shaft of gearbox through shaft coupling, the first output shaft of gearbox is the sprocket shaft of the drive sprocket of part one side that lifts seedlings, its top is installed with the transmission gear that lifts seedlings, the transmission gear that lifts seedlings engages with the transfer driven gear that lifts seedlings, the transfer driven gear axle top that lifts seedlings is installed with the transmission drive pulley that lifts seedlings, the sprocket shaft top of the drive sprocket of the part that lifts seedlings opposite side is installed with the driven transmission belt pulley that lifts seedlings, and belt connects lift seedlings transmission drive pulley and the driven transmission belt pulley that lifts seedlings.
