Abstract

The utility model provides a corn harvesting machine which relates to crop harvesting machinery. The utility model solves the problem that medium and small sized corn harvesting machines in the prior art can not carry out harvest to the conditions of inconsistent planting row pitches and nonuniform closing degree of corn. The utility model is mainly composed of a cutting mechanism, reeling and feeding mechanisms, an ear picking mechanism, a straw crushing mechanism and an ear transferring and collecting mechanism, wherein both two reeling and feeding mechanisms are composed of two sets of identical structures; each set of structures is respectively composed of a chain wheel, a chain, a tine, a tine shaft and a sliding plate; the only one pair of snapping rolls of the utility model is positioned at the middle lower part of the lower reeling and feeding mechanism and connected with a gearbox; the tine is arranged on the tine shaft; both ends of the sliding plate are circular arcs which share the same circle center with the corresponding chain wheels; the slide plate is fixed on a frame; the slide plate is adjacent to the chain at an outward side and simultaneously and tightly attached with one side of the tine. A cutting knife is positioned at the lower part of the lower chain wheel. The utility model is especially matched with a small four wheel tractor to simultaneously harvest two lines of corn.

Description

Maize harvesting machine

Affiliated technical field

The utility model relates to a kind of facility of crops harvesting equipment, particularly harvesting corn.

Background technology

Existing maize harvesting machine is of a great variety, but structural design is all similar, nothing more than by cutter sweep, feeding unit, ear-picking unit, straw millstone and spike collecting device etc.Because China is vast in territory, the zone of corn planting is wider, exists on kind, geographical conditions, weather conditions and planting habit than big-difference, various informativeization of plantation, cause the corn planting line-spacing to differ, the density inequality brings inconvenience for the mechanized harvest corn.Existing one-stop operation can be gathered in the crops two row or the above maize harvesting machine of two row simultaneously, all is mainframe, costs an arm and a leg, and has exceeded the purchasing power of general peasant household, is difficult to popularize.And existing small-sized corn reaping machine especially is suitable for the hilly country, mountain area, with the maize harvesting machine of tractor with small four wheels do traction, can only finish the single file harvest operation, and efficient is lower, and the results cost is higher, neither a kind of desirable maize harvesting machine.

Summary of the invention

The purpose of this utility model is the defective that exists at prior art, provides that a kind of cost is low, results efficient height, is not planted the line-spacing restriction, is suitable for the small-sized corn reaping machine of multiple landform operation.The utility model is the further improvement of making at prior art, its technical scheme is: it comprises dials the standing grain intake mechanism, snapping bar and cutter, on it has, dial the standing grain intake mechanism for following two, described group of standing grain intake mechanism is made up of two groups of identical structures, this structure lays respectively at the conplane left and right sides, every group of structure is respectively by sprocket wheel, chain, moving tooth, moving tooth axle and slide plate are formed, moving tooth is " L " shape, moving tooth and moving tooth axle are hinged, the two ends of slide plate are circular arc, circular arc and corresponding sprocket wheel concentric, slide plate are contained on the frame and near an outside chain and a limit being close to moving tooth, cutter is positioned at the below of bottom sprocket wheel.

The work that hockets of adopt the utility model sprocket wheel, chain, moving tooth, moving tooth axle, slide plate to combine to constitute symmetrical structure, left and right sides moving tooth ecto-entad can not be subjected to the influence of line-spacing, simultaneously to about two row corn standing grain fringes gather in the crops.

Embodiment

The utility model maize harvesting machine mainly is made up of cutting mechanism, group standing grain intake mechanism, corn snapping unit, straw disintegrating mechanism and fruit ear transmission collecting mechanism.The main distinction of the utility model and prior art is to dial the standing grain intake mechanism.Fig. 1, shown in Figure 2, the utility model has upper and lower two to dial the standing grain intake mechanism, each is dialled the standing grain intake mechanism and is made up of two groups of identical structures again, this structure lays respectively at the conplane left and right sides, and every group of structure is made up of sprocket wheel (1), chain (2), moving tooth (3), moving tooth axle (4) and slide plate (6) respectively.Snapping bar (5) is arranged in the below that the standing grain intake mechanism is dialled in the bottom, and is connected with gearbox.Moving tooth (3) is " L " shape, and moving tooth (3) is contained on the moving tooth axle (4), can rotate flexibly, and moving tooth axle (4) is the bearing pin on the chain (2).The two ends of slide plate (6) are circular arc, and circular arc and corresponding sprocket wheel (1) concentric, slide plate (6) are fixed on the frame and the chain (2) of a close outside side, are close to a limit of moving tooth (3) simultaneously.Cutter (7) is positioned at the below of bottom sprocket wheel (1).Sprocket wheel (1) and cutter (7) all have power transmission shaft, and this power transmission shaft is connected with power drive mechanism respectively.After above-mentioned installation, can begin operation.During operation, complete machine moves forward, and cutter (7), snapping bar (5) begin to rotate, and the sprocket wheel (1) of constant speed rotation drives moving tooth (3) by chain (2) and moves to snapping bar (5) direction.When near the corn straw, at first cut off the corn straw by cutter (7), the corn straw that is vertical that moving tooth (3) synchronous working of upper and lower immediately " L " shape will be cut off is dialled and transports between a pair of snapping bar (5), promptly finishes and once feeds work.After feeding work was finished, moving tooth (3) continued motion, and snapping bar (5) the then whole corn straw of clamping rolls downwards and send, and forced corncob to break away from the corn straw and rolled in the tassel-conveying groove, was collected in the maize cob collector at last.When moving tooth (3) moves to snapping bar (5) when locating, the corn straw is moved downward by snapping bar (5) clamping, owing to also be in erectility in the corn straw short time, therefore, stop moving tooth (3) to continue motion, the end points on another limit of moving tooth this moment (3) just in time breaks away from slide plate (6), and moving tooth (3) is forced to rotate around moving tooth axle (4), just throw oneself on one's knees automatically, avoid straw to be hauled out by moving tooth (3).When moving tooth (3) moves to slide plate (6) outer point, a limit of moving tooth (3) is lived by slide plate (6) shelves, moving tooth (3) can only rotate around moving tooth axle (4), finally make a limit of moving tooth (3) go to parallel with slide plate (6) outer surface, and be close to slide plate (6) and move, restriction moving tooth (3) can not freely rotate before at disengaging slide plate (6), keeps the duty that straightens always.So far, finished a periodic duty.The utility model has upper and lower two to dial the standing grain intake mechanisms, its objective is the straw of the cutting off state of being kept upright that guarantees.Since dial the standing grain intake mechanism by about two groups of identical mechanism forms, the moving tooth of two groups of mechanisms (3) alternation, the length of chain (2) satisfies maximum plantation line-spacing, can gather in the crops two simultaneously and go corns.The utility model is simple in structure, and is the most suitable supporting with tractor with small four wheels, carries out operation on complicated landform.
