Abstract

The utility model provides a knapsack type power-driven two-purpose rice-wheat harvester using a small gasoline engine and an automatic centrifugal clutch to form a power mechanism; a transmission device is composed of a clutch, a flange (11), a transmission shaft (8), a small bevel gear (7) and a big bevel gear (5) drives a harvesting device composed of a driving shaft (4), a tray (3), a hand grain frame (1) and circular saw blades. The utility model has the advantages of compact structure and convenient operation and maintenance, which can be used in sunny days and rainy days; the utility model is an ideal portable type harvesting agricultural implement.

Description

The dual-purpose grain header of power knapsack rice wheat

The utility model relates to small-sized agricultural tool.

China south of the lower reaches of the Yangtze River and farmland, knob, mostly be the ridge field greatly, be close to the field, terraced fields, the field piece is less, the discrepancy in elevation is bigger, the nonirrigated farmland sporadicly disperses, mostly be hillside fields, hillock, ladder ground, the harvesting of these field crops, combine and make with the swather of walking tractor matching is not used, once once used multiple grain header leaves unused also because of multiple reason, and the peasant have to pick up the harvesting of hand sickle again, remain tired hardships with one's back bent, vast farmers thirsts for having new suitable small-sized harvesting farm machinery to come out.

The purpose of this utility model is to provide a kind of power knapsack rice wheat dual-purpose grain header, and this grain header is in light weight, and the harvesting performance is good, and long service life is easy to maintenance, and the fine rainy day can both gather in, and is good in economic efficiency, can satisfy the requirement of peasant household.

The purpose of this utility model is achieved in that the dual-purpose grain header of power knapsack rice wheat is made up of gasoline engine, centrifugal clutch, power transmission shaft, gear, driving shaft, disk saw blade, grain lifting frame, with miniature gasoline engine as motive power, drive cutter sweep by transmission mechanism, grain lifting frame can make the neat one-tenth of the crops after the cutting that ground is swung on one side, is particularly suitable for the agriculture requirement of south rice field threshing while gathering in.

The dual-purpose grain header of power knapsack rice wheat is reasonable in design, and compact conformation is easy to operate, the cut crop lay is neat, and percent of loss is little, and harvesting quality is good, hour work efficiency 0.6-0.8 mu, this machine dependable performance, wide adaptability, both but the harvester for rice wheat also can be gathered in beans, careless class, applied this grain header, can promote grain-production, promote the agrotechnique progress, alleviate peasant's labour intensity and financial burden, certain market prospects are arranged.

Below in conjunction with Figure of description, the utility model is illustrated it in detail.

Fig. 1 is the dual-purpose grain header structural representation of power knapsack rice wheat.

Among the figure: the 1-grain lifting frame, 2-platen sieve cap, the 3-pallet, the 4-driving shaft, the 5-large bevel gear, the 6-gear-box, the 7-cone pinion, the 8-power transmission shaft, the 9-sleeve pipe, 10-connects disk casing, and 11-connects dish.

Fig. 2 is the grain lifting frame structural representation.

Among the figure: the 12-back stay, block bar on the 13-, bar is blocked in sieve hole, 14-location among the 15-, and 16-holds up the standing grain base plate, 17-brace, 18-front support rod.

As Fig. 1, shown in Figure 2, the end (among Fig. 1 A to shown in) that connects disk casing (10) is connected with the gasoline engine body, connecing dish (11) is connected with clutch, sieve hole on the bell housing, flange and the corresponding flange of gasoline engine output match, connect with Luo Zhu, power transmission shaft (8) right-hand member square toes portion is connected with the clutch rolling disc, power transmission shaft (8) left end threaded portion section is connected with cone pinion (7), cone pinion (7) is contained in the gear-box (6) with large bevel gear (5) engagement, the driving shaft (4) of large bevel gear (5) connects pallet (3) by the conical surface, disk saw blade is contained in driving shaft (4) termination, again platen is put, and tighten platen sieve cap (2), sleeve pipe (9) outside power transmission shaft (8), sleeve pipe (9) one ends and gear-box (6) end tight fit, sleeve pipe (9) other end with connect disk casing (10) and be slidingly matched, at sleeve pipe (9) suitable position the operator handle that can move forward and backward is housed, braces connects by connecing disk casing (10); Grain lifting frame (1) is by holding up standing grain base plate (16), on block bar (13), in block bar (15), back stay (12), front support rod (18), brace (17) is formed, during installation, driving shaft (4) and pallet (3) pass the neutral gear of holding up standing grain base plate (16) of grain lifting frame (1) in elder generation, and then installation disk saw blade, grain lifting frame (1) hold up A on the standing grain base plate (16) after the pairing cover is buckled in sleeve pipe (9) with the locking of both sides sieve bolt (among Fig. 2 A to shown in), sieve hole, location (14) will hold up standing grain base plate (16) to be close on sleeve pipe (9) by sieve bolt on the gear-box (6), with grain lifting frame (1) stationary positioned.

The dual-purpose grain header of power knapsack rice wheat except that connect dish (11), connect disk casing (10), power transmission shaft (8), sleeve pipe (9), gear-box (6), driving shaft (4), grain lifting frame (1) be from workpieces, all the other all can adopt outsourcing piece, as select 1E36F two-stroke single cylinder air-cooled gasoline engine (weight 3.5kg), diameter  250mm saw blade, automatic centrifugal clutch for use, the complete machine net weight of making appearance and size 1642 * 500 * 440mm has only 8.35kg.

The dual-purpose grain header of power knapsack rice wheat adopts miniature gasoline engine as power, and it is connected compactness with transmission device with cutter sweep, and grain lifting frame is provided with rationally, and the harvesting performance is good, can satisfy the specification requirement of China's south multiple kinds of crops harvesting agronomy fully.
