Abstract

The utility model relates to a wheat and rice double-purposed reaper, which is mainly composed of a bottom plate, a supporting plate, a drive nail disk, a tooth gear, a shaft, a circular disk blade, a straight blade, a nail dialing and guiding wheel, etc. The reaper is of a manual push type, the reaper is rotated to march forwards through the friction generated by the contact between the drive nail plate and the ground, consequently a pair of bevel gears is driven to rotate, and the circular disk blade is rotated at high speed through the shaft drive of the bevel pinions to form a kinetic cutting; meanwhile, the nail dialing and guiding wheel is also arranged, and the nail dialing and guiding wheel is rotated and forcibly guides and feeds rice and wheat to be cut and reaped through the counterforce of the reaper which marches forwards, and thus, the cutting power is strong. The utility model has the advantages of simple structure, small size, light weight, convenient operation, and low cost.

Description

Double-purposed cutters for wheat and rice

The utility model relates to a kind of agricultural harvesting facility, especially a kind of manual harvester for wheat and rice.

At present, the various harvesting facility kinds of using on the agricultural are a lot, large-scale combine, though automaticity is very high, but only be applicable to tract, and its volume is big, costs an arm and a leg, owing to the restriction of aspects such as the energy, these ability to bears to a large amount of individual producers in the vast rural area of present China are not suitable again.Various manpower harvesters have also appearred in recent years, as 4GR-1 type rice harvester, because its two straight knife sheets are V-shaped fixing, it can only be applicable to that harvesting paddy rice and not being suitable for shears through the wheat, rice harvester is when harvesting rice like this, having shortcoming is when staff is held harvester work upwards trend often to be arranged, and until the rice tip, the rice stubble that cuts out like this is irregular.Still use the harvesting of bending over of traditional farm implements-reaping hook when the vast rural area of China shears through the wheat, so not only labour intensity is big but also labor productivity is low.

The purpose of this utility model is to design a kind of novel dual-purpose harvester of wheat rice in order to overcome above-mentioned weak point, its groundwork principle is to have changed scissor incision principle and adopt garden disc blades rotation cutting, its principal character is to use the garden disc blades of straight knife sheet that two V-types install and two rotations to combine simultaneously to cut, be provided with again and dial nail guide wheel, it can feed cutting by force with the wheat rice, to increase cutting intensity.Implementation method is when people's hand propelled harvester advances, the wheat rice that the straight knife sheet will be thicker when the wheat rice enters harvester V-type mouth has carried out preliminary cutting, driving the nail dish at the same time contacts the frictional force that produces and makes nail dish rotation itself that cutter is advanced with ground, thereby drive the rotation of a pair of bevel gear, make garden disc blades rotation by the angular wheel shaft transmission again, reaction force when at this moment advancing owing to cutter makes the nail guide wheel of dialling that is installed in V-type straight knife sheet both sides rotate, by force dish flute profile blade porch, remaining wheat rice feeding garden is cut, finish whole harvesting processes.And the rotary speed of garden disc blades depends on the pace of harvester for wheat and rice.
