Abstract

The utility model discloses a corn harvester, which has simple structure and low manufacturing cost and can adapt to various terrains. The corn harvester mainly structurally comprises a traveling mechanism, a frame, a power device, a cutting and pulverizing device, a collection bin, and an ear picking device. The ear picking device is positioned above the frame and is connected with the power device through a belt pulley, the collection bin is arranged below the ear picking device, a vertically-through groove is formed on the collection bin, and the cutting and pulverizing device is arranged on the frame below the groove. The corn harvester has the advantages of simple structure, low manufacturing cost and so on, is suitable for being widely used in rural areas, and can adapt to various terrains including mountain areas, hilly areas, terraced fields and so on.

Description

Maize harvesting machine

Technical field

The utility model relates to a kind of agricultural machinery, particularly a kind of Miniature Corn-harvester.

Background technology

In recent years, along with China's development of rural economy, the examination of Tendency of Agricultural Machinery in China journey is more and more higher, at present, the results of most of crops have all realized mechanization, and the harvest machinery technology of corn also is not very ripe only, in the vast rural area of China, corn also needs manually to pluck receipts.Present maize harvesting machine is many to be made up of haulage gear, corn snapping unit etc., its major defect is: complex structure, manufacturing cost height, cause the selling price costliness, be not suitable for promoting in the rural area, and because volume is bigger, therefore can only in having the farmland of tractor road, use, still, just can't use at a large amount of mountain area of China, knob and terraced fields.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, low cost of manufacture, can adapt to the maize harvesting machine of various ground type.

The technical scheme that the utility model adopted is: a kind of maize harvesting machine, comprise running gear, frame, power set, cutting and grinding device, collecting bin and ear-picking unit, described ear-picking unit is positioned at the frame top, be connected with power set by belt pulley, described ear-picking unit below is provided with collecting bin, described collecting bin is provided with the groove of up/down perforation, and the frame of described groove below is provided with the cutting and grinding device.

Described ear-picking unit is by one initiatively plucking roller, drivenly plucking roller and pluck the roller gearbox and form, described initiatively pluck roller one end by gear respectively with pluck roller gearbox power take-off, the driven roller of plucking is connected, two pluck the roller other end by on bearing and the frame, pluck the roller leading portion and be the constraint spiral, the rear end is for plucking the fringe spiral.

Described cutting and grinding device is made up of knife rest, cutter shaft and cutting and grinding cutter, and described cutting and grinding cutter is by bolt and knife rest Joint, and knife rest is connected with power take-off by cutter shaft.

Described collecting bin one end is connected as a single entity by hinge and frame, and the other end is placed horizontally on the frame.

The beneficial effects of the utility model are: simple in structure, low cost of manufacture, and suit in the rural area wide popularization and application, and can adapt to various ground type, comprise mountain area, knob and terraced fields etc.

Embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, present embodiment comprises running gear, frame 1, gasoline engine 2, cutting and grinding device 3, collecting bin 4 and ear-picking unit 19, ear-picking unit 19 is positioned at frame 1 top, be connected with gasoline engine 2 by belt pulley 5, be provided with collecting bin 4 under the ear-picking unit 19, collecting bin 4 one ends are connected as a single entity by hinge 17 and frame 1, the other end is placed horizontally on the frame 1, collecting bin 4 simultaneously offers the groove 6 of up/down perforation to hold corn straw towards corn straw, be provided with cutting and grinding device 3 on the frame below the groove 61.Ear-picking unit is by one initiatively plucking roller 7, drivenly plucking roller 8 and pluck roller gearbox 18 and form, initiatively pluck roller 7 one ends by gear respectively with pluck roller gearbox 18 power take-offs 9, the driven roller 8 of plucking is connected, two pluck the roller other end by on bearing 10 and the frame 1, pluck the roller leading portion and be constraint spiral 11, the rear end is for plucking fringe spiral 12.Cutting and grinding device 3 is made up of knife rest 13, cutter shaft 14 and cutting and grinding cutter 15, and described cutting and grinding cutter 15 is by bolt 16 and knife rest 13 Joints, and knife rest 13 is connected with power take-off by cutter shaft 14.During work, gasoline engine 1 drives by gearbox and plucks 9 rotations of roller gearbox power take-off, power take-off 9 is initiatively plucked roller 7 by gear driven and is plucked roller 8 relative rotations with driven, be both therewith, gasoline engine 1 is connected with cutter shaft 14 by gearbox, and cutter shaft 14 drives knife rest 13 and 15 rotations of cutting and grinding cutter.During harvesting corn, promote maize harvesting machine, corn straw is arranged in the groove 6 of collecting bin 4, and at this moment, the two constraint spirals 11 of plucking roller pull up corn straw and inwardly screw in, until plucking fringe spiral 12 places corncob is taken, corncob falls into the collecting bin 4 of below automatically, and corn straw moves downward to cutting and grinding device 3 under the turning effort of plucking fringe spiral 12, pulverize through cutting and grinding cutter 15, promptly finish a strain harvest corn.When take advantage of in the collecting bin 4 fill with corn after, collecting bin 4 along hinge 17 upset, is poured out corn and is got final product.
