The utility model relates to a reaper, and consists of an electric motor, a frame, an oscillating guide-bar mechanism, a cutter blade and a straw-guide railing. The electric motor and the transmission shaft are vertical to the frame. A driven friction wheel and a pinion are arranged on both ends of the transmission shaft respectively and the radius of the driven friction wheel is several times of the radius of the pinion. One end of the rocker is connected with the one-third section of the gearwheel through a movable rotary pair, and the other end is connected with the cutter blade. Guided by the straw-guide railing, the cut straws are placed reversely on the rear of the frame in stack and pushed down into the reaper in stack by a straw-pushing board. The utility model adopts a fractional electric motor, and has a reaping width of 60 to 100 centimeters. The utility model has light weight, small bulk, simple structure, low price and operation by one person and can achieve a segmental mechanization of reaping and threshing in hilly areas.

Description

Light-duty wheat rice harvester

The utility model belongs to the agricultural harvesting machinery field.

The wheat paddy rice harvesting platform of Shi Yonging generally need use with tractor now.Therefore the complete equipment volume is big, heavy, can't use substantially in the fritter field, even use also can't reach ideal effect reluctantly.Buy such a set of equipment price height, the peasant household of dispersion does not have economic capability to buy at all.Having the people to design a kind of in 98 years is the small harvester of power with internal combustion engine, with respect to the utility model, constructs more complexly, so price is much higher.There was the people to design a kind of hand-push type grain header in 2001.The patent No. is respectively ZL:98229492.1; ZL:01212765.5.

The purpose of this utility model provides each grow wheat paddy rice dual-purpose grain header, is useful for the operation of fritter field, improves harvesting efficiency, makes the knob realize harvesting and threshing segmentation mechanization.

The technical solution of the utility model is achieved in that the critical piece of this grain header comprises electromotor, support, oscillating guidebar mechanism, blade, rice crop guiding railing, pushing hands.The power of electromotor is by a pair of friction pulley, power transmission shaft, and pair of engaged gears, oscillating guidebar mechanism drive the reciprocating cutting straw of blade.The friction wheel is installed on and is driving wheel on the motor reel, and big friction wheel is installed on the power transmission shaft upper end and is driven pulley, and pinion is installed on the lower end of power transmission shaft.The radius of driven friction pulley is five times of pinion radius, is delivered to through pinion according to the power on the driven friction pulley of lever principle to enlarge five times on the gear wheel.One end of rocking bar is attached at 1/3 place of gear wheel with mobile rotary pair, and the other end links blade with mobile rotary pair.The length of rocking bar two arms about equally.Therefore be delivered on the blade of the rocking bar other end according to the power on the lever principle gear wheel, will enlarge two to four times.Electromotor and power transmission shaft are all perpendicular to support.The utility model adopts the high speed fractional electric motor, is delivered to after the expansion through deceleration and twice pair of power just to reach the desired standard of grain header on the blade.The swath of this machine is (60-100 a centimetre).

The beneficial effects of the utility model are that it is not only in light weight, volume is little, and a people just can use, and price is low, and harvesting speed is to use more than ten times of reaping hook, and the fritter field is easy to use.Can harvesting interplant the ground wheat, can make the knob realize harvesting and threshing segmentation mechanization.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model overall structure sketch.

Fig. 2 is the transmission mechanism schematic diagram.

Among the figure 21, support; 2, electric case; 3, rice crop guiding railing; 4, pushing hands; 5, rice crop pushing plate; 6, rice crop pushing plate hand controller; 7, backboard; 8, blade; 9, wheel; 10, electromotor; 11, active friction wheel; 12, driven friction pulley; 13, rice crop plucking bar; 14, power transmission shaft; 15, pinion; 16, gear wheel; 17, rocking bar; 18, rocking bar fulcrum; 19, mobile rotary pair, 20, link blade and move rotary pair.

Electromotor 10 is housed in the electric case, active friction wheel 11 driven friction pulley 12 rice crop plucking bars 13, electromotor and power transmission shaft are all perpendicular to support 1, and driven friction pulley 12 is installed on the upper end of power transmission shaft 14, and pinion 15 is installed on the lower end of power transmission shaft 14.Drivenly rub that to examine wheel 12 radius be five times of pinion 15 radiuses, rice crop plucking bar 13 is installed on the driven friction pulley 12.The radius of rice crop plucking bar 13 and driven friction pulley 12 is the angle of (120-160 degree).Its role is to promote backward straw.Rice crop guiding railing A-B section slopes inwardly, and rice crop guiding railing D-C section and A-B section tilt in the same way, will tilt along the hurdle when the straw of cutting off enters the tilting section rice crop guiding railing, is convenient to put upside down.The effect of pusher baffle plate 7 is to block and moves after straw continues, and forces straw to fall down in order, and rice crop pushing plate 5 is equipped with by hand controller 6 controls in the rear portion, is used for the straw that the falls down grain header that pushes in heaps.Pinion 15 and gear wheel 16 engagements.Gear wheel 16 is formed rotary pair with support 1.One end of rocking bar 17 is attached at 1/3 place of the radius of gear wheel 16 with mobile rotary pair 19, and the other end links blades 8 with mobile rotary pair 20.Rocking bar 17 is a rocking bar fulcrum 18 with the rotary pair that support 1 is formed, and rocking bar fulcrum 18 equals the distance of rocking bar fulcrum 18 to blade 8 to the distance in gear wheel 16 axle center.Rocking bar fulcrum 18 is (20-30 a centimetre) to the distance in gear wheel 16 axle center.

An embodiment of the present utility model installs wheel 9 to be convenient to light promotion when getting wheat.

When another embodiment of the present utility model was harvesting paddy, because wheel is used in paddy field inconvenience, but water had buoyancy upwards, therefore wheel 9 need not be installed.
