Abstract

The utility model belongs to a rice and wheat dual-purpose harvester. A micro power device is installed on a frame. Power is transmitted to a motorized sprocket through a chain. A friction wheel is installed on the motorized sprocket and is in close contact with a traveling wheel. The traveling wheel is equipped with a chain plate. Power is respectively sent to a rolling cutter and a rice harvester. After the rice and wheat are cut and gathered into bundles, the rice is pushed to the side of the harvester by the rice discharging device. The harvester has a small size, light weight, low power consumption, and is easy to operate. It is suitable for terraced field operations in mountainous areas.

Description

Miniature power harvester for both rice and wheat

The utility model relates to a kind of agricultural machinery, the dual-purpose grain header of particularly a kind of rice wheat.

Present being seen grain header type is more, high-power combine is arranged, also useful small diesel engine is made the grain header of power, also have many hand reapers, as foot-operated, manual type, abdomen pushing-type hand reaper, various grain headers have all solved over the past thousands of years to some extent, and people bend over to cut rice and wheat, the hard labor problem of face towards the loess back of the body towards the sky, the part but existing grain header also comes with some shortcomings respectively, only be fit to the large stretch of cropland's operation in Plain as combine, the price height has only farm or mechanization intensive production just can buy; The grain header price that small diesel engine is used as power is also expensive slightly, and the fritter terraced fields in many mountain areas are made does not use, and is flexible not enough; Though various hand reapers are flexible, convenient, cost is low, the gas of also requiring great effort can only could use by able-bodied labour, and the people of poor physical capacity or women use still inconvenient.People have also designed some novel manual grain headers in recent years, disclose as Chinese patent 96235071.0 " to hobboing cutter tool manual harvester for rice and wheat " two grain headers to the hobboing cutter tool have been housed on a kind of frame, its resistance is little, easy to operate, efficient is high, but also there are some shortcomings in this grain header, it is not suitable for the dark mud paddy-field-working in south, it is reasonable not enough to receive standing grain device and discharging design, main is prime of life able-bodied laborer operation during this grain header only is fit to, and the weak work of muscle power uses still feels more painstaking and tired.

The purpose of this utility model provides a kind of harvester for both rice and wheat that miniature dynamic equipment is housed, and it is laborsaving, easy to operate, cost is low, consumption of power is little, but harvesting efficiency then improves greatly.

The utility model is realized in following mode: miniature power harvester for both rice and wheat comprises frame, handle, road wheel, to roll blade, and receipts standing grain device, parts such as removal device, be characterized in: miniature dynamic equipment is housed on this grain header, this miniature dynamic equipment links to each other with motor-driven sprocket wheel by chain, on the motor-driven sprocket wheel friction pulley is housed, friction pulley is made with rubber or engineering plastics, it is close on the road wheel, chain drum also is housed on the road wheel, and link on the gear by chain, one of gear shaft is linked on the roll blade, transition wheel is equipped with in the other end, and with the feeding belt gears engaged, feeding belt is provided with pin every one section, the frame side is provided with hopper, feeding belt will hold together into handle from the rice wheat that roll blade is cut, and collect hopper by feeding belt, the row's of being equipped with standing grain device on the hopper, also have pull bar to link on the driving lever of row's standing grain device on the handle, when hopper during to the quantity that requires, with the driving lever of pull bar control row standing grain device, dials out to the rice wheat one side of grain header with the rice wheat harvest.

The operation principle of this miniature harvester is: when starting miniature dynamic equipment, power passes on the motor-driven sprocket wheel by chain, on the motor-driven sprocket wheel friction pulley is installed, friction pulley promptly drives road wheel and rotates forward, finish the course of work of walking, owing on the road wheel chain drum is housed, chain drum is equipped with chain, and power is passed on the gear, and one of gear shaft is linked roll blade, the other end is equipped with transition wheel, and the drive belt pulley, belt pulley is provided with pin again, cuts off the rice wheat when roll blade is moved forward, pin is about to the rice wheat harvest and holds together the row's of delivering to standing grain device hopper, and Artificial Control is dialled the side that is put into grain header to ground with one in rice wheat then.

The utility model is compared with existing grain header, and substantive distinguishing features that has and progress are:

1. little, in light weight, the complete machine of volume heavily has only the 30-40 kilogram, and is all lower than at present all Motor-driven harvester costs, and easy and simple to handle.

2. the harvesting efficiency height than manually waving sickle harvesting piece 3-4 doubly, improves more than 1 times than existing many manual receipts motor speed, and general normal labour per hour can gather in about 1 mu.

3. can be manual, motor-driven dual-purpose, as long as releasing lever can manually promote the harvester for rice wheat, and stir pull bar, and open miniature dynamic equipment, can carry out motor-driven walking and harvesting operation again, power consumption is very little, as uses the engine of common aiding bicycle, and every liter of gasoline can be worked continuously 2 hours.

4. existing big-and-middle-sized grain header can only gather in the large tracts of land field, can not adapt to the mountain area terraced fields, can not be at the paddy-field-working that has mud to sink, the hand-push type grain header can not gather in mud water in field rice, and this grain header is not subjected to field, mud influence, and the operation that also can do as usual of the rice field of 30 centimetres of dark mud is arranged.

Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:

Fig. 1 is the side schematic view of miniature power harvester for both rice and wheat;

Fig. 2 is the upward view of miniature power rice wheat harvest machine.

From figure, see, miniature dynamic equipment 38 of the present utility model is linked on the motor-driven sprocket wheel 42 by chain 12, they all are contained on the support plate 9, dynamic equipment 38 can be supplied with fuel oil with fuel tank 37, the gauge tap 10 of dynamic equipment can be contained on the handle 15, motor-driven sprocket wheel 42 is equipped with friction pulley 11, contacts with road wheel 22, and road wheel 22 is provided with chain drum 21, there is bearing 39 outside and is connected with support 8, the chain of chain drum 21 is linked on the gear, and there are chain guard 41, gear shaft one end and roll blade 26A in the gear outside, 26B connects, transition wheel 35 is equipped with in the other end, transition wheel 35 and 36 engagements of main pulley gear, and drive feeding belt 34 rotations, the other end also is provided with from belt pulley 33; Hobboing cutter tool 26A and 26B are overlapped at knife-edge part, direction of rotation, the grain header front portion is two dials and to collude 1, and with standing grain the to be gathered in edge of a knife cutting of dragging on, edge of a knife front is provided with blocks flitch 13, prevent that straw from twining, receive standing grain device 2 and be contained in edge of a knife front, standing grain to be gathered in is drawn in into roll blade 26A and 26B are cut, cut rice straw is delivered to hopper 27 with feeding belt 34, spur pull bar and removal device 28 by handle after collecting some, will become the rice wheat of handle to dial the side that is put into grain header.The action of starting for hand being spared doing, dialling standing grain, push rod 16 also is equipped with in handle 15 fronts, can promote to cut rice and wheat with belly.
