Abstract
The utility model provides a sprocket type manual wheat harvester. The sprocket type manual wheat harvester comprises a handle, a main beam, a claw wheel and a guide rod. The utility model is characterized in that the front end of the main beam is provided with a transverse bracket and a fixed comb tooth type cutting knife, the lower part of the bracket is provided with a sprocket wheel group, and a serrated knife is arranged on a chain. A vertical rod is also arranged on the bracket, the upper end of the vertical rod is provided with a flywheel, and the flywheel is connected with a large concentric sprocket wheel arranged on the claw wheel via the chain and connected with a drive sprocket wheel via a flexible shaft. The utility model has the advantages of simple structure and convenient operation.
Description
The utility model belongs to a kind of improved harvesting machinery, the manual harvester for wheat of particularly a kind of sprocket-type.
In the prior art, manually harvester for wheat has scissor and two kinds of gear types.The former deficiency be that effort and efficient are low; And the gear type more complicated.Both processing and assembly precision require all than higher, and blade forming V-shape, when work two blades can produce forward component naturally, when straw is run into blade and is not reached the handing-over mouth of two blades, just pushed away forward by this component, cause a part of straw to be pushed over and be difficult to cut off, occur leaking and cut phenomenon.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, the easy to operate and manual harvester for wheat of sprocket-type that do not allow leakiness to cut.
Structure of the present utility model is such: as depicted in figs. 1 and 2, same as the prior art, this machine includes handgrip 1, girder 2, claw wheel 3 and guide rod 4, done such improvement for realizing above-mentioned task, front end at girder 2 is provided with a horizontal support 5, fixing comb formula cutter 6 is housed on support 5, below support 5 two ends, respectively be provided with a drive sprocket 7 and a driven sprocket 8, the chain 9 that is attached thereto is equipped with serrated knife 10, serrated knife 10 is close to comb formula cutter 6 belows, on support 5, also be provided with a montant 11, a flywheel 12 is housed in the top, this flywheel 12 is connected with concentric hinge wheel 14 on being arranged at claw wheel 3 by chain 13, and passes through flexible axle 15 and be connected with drive sprocket 7.
The utility model is work like this: during harvesting, along with claw wheel 3 is goed ahead and is just driven hinge wheel 14 and rotate, driving drive sprocket 7 by chain 13, flywheel 14 and flexible axle 15 rotates, make chain 13 drive the straw that serrated knife constantly circulates and 6 montages of comb formula cutter will enter between comb formula cutter 6 broach and cut off, the straw after cutting off fitly overlays on the ground along guide rod 4.Because the broach of comb formula cutter 6 is fixed, and is again straight-tooth, arranges closelyer, therefore the straw that enters between broach is not easy to be pushed over.Though serrated knife 10 also have one forward with a horizontal component, it makes a concerted effort with the broach handing-over straw to be cut off very soon, is pushed over and leaks the phenomenon of cutting so the utility model can overcome straw.In addition, transmission mechanism of the present utility model all adopts standard component, and the processing technology of other part requires not high again, thereby it is simple in structure that the utility model is also had, make easily and the advantage of keeping in repair, and also easy to operate.
Description of drawings
Fig. 1 is the front view of the utility model concrete structure.
Fig. 2 is the vertical view of Fig. 1.
When implementing, support 5 is that angle is preferably 60～80 degree with girder 2, makes the comb body and the broach of comb formula cutter 6 in an acute angle, can further reduce to cover to leak and cut phenomenon, and the straw after helping being cut can be neatly on one side.
The utility model is particularly suitable for shearing through the wheat, also can be used for two season rice harvesting.
Claims (2)
1, the manual harvester for wheat of a kind of sprocket-type, include handgrip 1, girder 2, claw wheel 3 and guide rod 4, it is characterized in that being provided with a horizontal support 5 at the front end of girder 2, fixing comb formula cutter 6 is housed on support 5, below support 5 two ends, respectively be provided with a drive sprocket 7 and driven sprocket 8, the chain 9 that is attached thereto is equipped with serrated knife 10, serrated knife 10 is close to comb formula cutter 6 belows, a montant 11 also is housed on support 5, be provided with a flywheel 12 in the top, this flywheel 12 is connected with the concentric hinge wheel 14 that places claw to take turns on 3 by chain 13, and is connected with drive sprocket by flexible axle 15.
2, harvester for wheat according to claim 1 is characterized in that the support 5 and the angle of girder 2 are preferably 60～80 degree.
