Abstract

The utility model relates to a small-sized hand harvester, composed of a machine frame (6), a rubber wheel (7), a crank handle (2), an armrest (1), sprocket wheels (28), (22), (4), chains (23), (27), a rice holding frame (12), rice holding steel wires (13), (17), and a fixed blade (24). The small-sized hand harvester is provided with a plurality of moving blades (25). Each moving blade is driven by the chain (27) and is provided with two edges. The harvester is pushed forward by the left hand and the chest while the small-sized hand harvester is used, and the crank handle is shaken by the right hand to drive the blades to rotate and to realize harvesting. Because the moving blade (25) is rotary, the harvesting saves labor. The harvester has the advantages of little motive force consumption, light weight (only 20 kg), small turning radius, and quick harvesting (more than 0.5 mou or so per hour).

Description

Small-sized hand harvester

The utility model relates to a kind of hand grain header, is applicable to the harvesting of each grow wheat, paddy rice.

Present grain header all is the harvesting that is fit to into the large stretch of ground of piece, and lacks the grain header in fragmentary little plot.Though occurred small-sized grain header during the last few days, because cost height, operating difficulties, can only gather in neatly, highly little, paddy rice and wheat that density is little, and operating efficiency is lower, does not satisfy peasant's needs.

The purpose of the utility model provides a kind of small harvester that can satisfy peasant's needs, and it has, and volume is little, in light weight, simple to operate, price is low, high efficiency, can be fit to the paddy rice on the various plot, the harvesting of wheat.

The purpose of this utility model can realize with following measure.

Rubber tire is installed as running gear under frame, its walking power resources are installed the knife section of a plurality of spinning rollers again in the people on ledger-plate, utilize hand sprocket wheel to drive chain, drive knife section rotation again, and add and hold up standing grain mechanism just can realize the purpose of this utility model with double cutting edge.

Because therefore walking of the present utility model and harvesting power resources have saved energy resource consumption in the people.Because this machine mechanism is simply in light weight, it is very convenient therefore machine to be moved to other plot from plot; Particularly rotate, so consumed energy is little owing to knife section; This machine adopts hand as power, and this just makes cost reduce, and is simple to operate, and applies in the mountain area easily.The inventor did repeatedly experiment, cut wheat with the utility model and per hour cut 0.5 mu-1 mu.

Further introduce the utility model below by accompanying drawing.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the A-A cutaway view of Fig. 1;

Fig. 4 is the constitutional diagram of ledger-plate and knife section.

Can see that from Fig. 1,2 at frame 6 rear portions of being made by angle steel handrail 1 is installed, when the utility model operation, the people is just holding up handrail 1, and by handrail 1, the walking of promotion grain header.Be equipped with bearing 5 on frame 6, it is used for installing crank 2 vertical pivots; It can also be seen that from figure crank vertical pivot top also has a bearing 3, this bearing links by gusset piece and handrail 1 again, and crank 2 has had two bearings 3 and 5 supportings like this, and the location has also just been arranged.On the crank vertical pivot, be equipped with minor sprocket 4, and link by chain 23 and the minor sprocket 22 that is installed on the main shaft 9.It can also be seen that in frame 6 bottoms from figure, be equipped with rubber tire 7.Rubber tire 7 promptly is a support mechanism, also is running gear; Rubber tire is an independent suspension, therefore turns flexibly, and this is to having significance in the patch operation.From Fig. 1,2, it can also be seen that, be equipped with main shaft 9, be equipped with minor sprocket 11 on the main shaft 9 again, hinge wheel 22, belt pulley 18 and 14 in the front portion of frame 6.As long as firmly swagger 2, crank 2 will drive sprocket wheel 4 and arrive minor sprocket 11 and belt pulley 14,18 again by chain 23 drive sprocket wheels 22.Minor sprocket 11 meshes with chain 27 again.Can see that from Fig. 3 chain 27 is joining several sprocket wheels 28 simultaneously, when minor sprocket 11 rotated, chain 27 will drive sprocket wheel 28 simultaneously like this, and when minor sprocket 11 rotated, chain 27 will drive sprocket wheel 28 simultaneously and rotate together like this.Therefore also just hand power has been passed to here, on belt pulley 18 and 14, the belt 20 that has belt fastener is installed, because belt pulley 18,14 is installed on the main shaft 9, therefore hinge wheel 22 1 rotates, belt 20 also rotates certainly simultaneously, and the belt 20 of belt leather bracelet is to be used to holding up standing grain wheel 16 to rotate, so that make the wheat of cutting off transport to machine side surface at this moment.Knife section 25 is installed in below the sprocket wheel 28, just by sprocket wheel 28 driven rotary, therefore it be one can rotation of blade, see that from accompanying drawing 4 this blade has two blades, when knife section 25 circled, it can cut wheat 2 times like this, because blade rotates, so certain inertia is arranged, makes that to cut wheat laborsaving; With the knife section 25 corresponding ledger-plates 24 that are mounted on the base plate 10, ledger-plate is motionless, and the relative motion between two blades 24 and 25 just makes the wheat that enters the edge of a knife be cut off.Base plate 10 is to be fixed on the frame 6, and bearing 8 is arranged on base plate 10, and it is used for installing main shaft 9.Can also see also having a bearing 21 on the main shaft 9 on scheming, this bearing links by gusset piece and frame 6 again, and main shaft 9 has had two bearings 8 and 21 supportings like this, and the location has also just been arranged.Preceding bottom in frame 6 also has grain lifting rod frame 12, again thereon by holding up standing grain steel wire 17 and 13 and hold up standing grain wheel 16, straw separating plate 15.Shelves standing grain plate 19 is equipped with the forward position of base plate 10, it be used for shelves live the wheat cut off on the machine.Nearside divider 26 is made by steel wire.

The utility model is work like this, promote grain header with left hand, the right hand is swaggered 2, the rotation of crank 2 will drive sprocket wheel 4 and rotate together, power will pass through chain 23, sprocket wheel 22, main shaft 9, minor sprocket 11, chain 27,25 rotations of sprocket wheel 28 drive knife sections, because the rotation of knife section 25, make it relative motion arranged with ledger-plate 24, thereby the wheat that enters the edge of a knife is cut off, by the belt 20 that has belt fastener and handrail wheel 16 wheat is transported to the side of machine by the wheat cut off, thereby reach the purpose of this utility model.
