Abstract
The utility model relates to a harvesting machine of crops, in particular to a manual harvester. The harvester mainly comprises a frame, saw blades and a rotating shaft; the front end of the rotating shaft is provided with a driving wheel, the front end of the lower gear of the frame is provided with a driven wheel, a cross rail of the frame is provided with a pinch roller, the saw blade is sleeved outside the driving wheel and the driven wheel, and friction transmission is adopted between the driving wheel and the saw blade. Compared with the prior art, the utility model has the characteristics of simple structure, small, energy-conserving, manufacturing and use cost are lower, flexible operation etc, are the very strong crops harvesting machine of adaptability.
Description
The utility model relates to a kind of crops harvest machinery, especially a kind of manual grain header.
At present, China has the big machinery grain header, but its volume is big, complex structure, need consume fuel, use and manufacturing cost all than higher, can only be applicable to northern flat area; And the southern rice field of China is distributed in the mountain area mostly, is uneven, and the piece field is little, and all works contracted to households of rural area, and the field disperses, and therefore is badly in need of a kind of small-sized harvesting machinery; Now domestic relevant publication has been reported several small-sized electric grain headers, uses though it is fit to south, needs driven by power, and complex structure, and rural power seldom leads to the field, so its use also can be restricted.
The purpose of this utility model be exactly the defective that exists at above-mentioned prior art and provide a kind of simple in structure, do not need fuel and electric power, manual grain header easy to use.
Technical solution of the present utility model is: this manual grain header comprises frame, saw blade and rotating shaft, the rotating shaft front end is provided with driving wheel, the front end of frame lower gear is provided with driven pulley, the crosspiece of frame is provided with pinch roller, saw blade is enclosed within the outside of driving wheel and driven pulley, adopts frictional drive between driving wheel and the saw blade.
Take following measure, can make the utility model reach better effect:
Screw rod and the adjusting nut that can regulate its spacing is set between the last lower gear of frame.
The outside of rotating shaft is provided with sleeve pipe, is provided with bearing in the sleeve pipe.
The cross bar of frame is provided with the straw-blocking rod that can slide on it.
The lower gear of frame is provided with road wheel, and with the coaxial travelling gear that is provided with of rear walking wheel, travelling gear drives the conveyer belt gear and rotates.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure chart of conveyer belt part among Fig. 1.
Compared with prior art, the utlity model has simple in structure, volume is little, strong adaptability, energy-conservation, manufacturing and the advantages such as use cost is lower, flexible operation.
Below in conjunction with accompanying drawing, the utility model is described in further detail: this manual grain header mainly is made up of frame 10, saw blade 1, rotating shaft 9.Bearing 7 is blocked by sleeve pipe 8, two bearings 7 is passed in rotating shaft 9, driving wheel 5 is fixed on the front end of rotating shaft 9, the rear end of rotating shaft 9 is provided with the bar 11 of shaking hands, and the front end of frame 10 lower gears is provided with driven pulley 2, and saw blade 1 is enclosed within the outside of driving wheel 5 and driven pulley 2, the crosspiece of frame 10 is provided with pinch roller 6, below these two pinch rollers are mainly used to saw blade pressed to,, strengthen the frictional force between them with this contact area that increases saw blade 1 and driving wheel 5; Be provided with screw rod 4 and adjusting nut 3 between the last lower gear of frame 10, be used for regulating the spacing between the lower gear, regulate the elasticity of saw blade 1 with this; The cross bar 15 of frame 10 is provided with the straw-blocking rod 16 that can slide on it; The lower gear of frame 10 is provided with four road wheels 14, and with the coaxial travelling gear 13 that is provided with of rear walking wheel, travelling gear 13 rotates with gear 12 engagements, the axle 18 that gear 12 drives conveyer belt 17, thereby drives conveyer belt.
Operation principle of the present utility model is: a hand propelled grain header, catch the bar 11 of shaking hands to rotate on the other hand, rotating shaft 9 and driving wheel 5 and then rotate, saw blade 1 is driven, the crops of grain header front are just by sawed-off, and sawed-off crops are extruded on the conveyer belt 17 of grain header, and blocked by straw-blocking rod 16, unlikely overturning, along with crops are increased, straw-blocking rod 16 slides to the back, up to filling, take away straw-blocking rod 16 then, allow crop translate into the field, and straw-blocking rod 16 is relay in front, grain header moves on, because trailing wheel is rotating, the travelling gear 13 coaxial with trailing wheel and then changes, and driven gear 12, thereby drives conveyer belt 17 motions, crops above the conveyer belt 17 are transported to the back automatically, work circularly like this.
