Description

Portable rice harvester

This full mold belongs to the farm machinery technical field, is specifically related to a kind of portable rice harvester.

The rice mechanization harvesting is the needs of modern agricultural development.Present paddy rice harvesting technology also has combine and Small machine for harvesting and drying grain in sun except that adopting the harvesting of conventional method reaping hook.Artificial reaping hook harvesting labour intensity is big, and production efficiency is low.The high efficiency of combine relatively is suitable for the large tracts of land operation, and the planting patterns of paddy rice adopts the plantation of little plot more, and large-scale agricultural machinery difficulty is put to good use; Be moist because of the grain of rice of cutting off simultaneously, so also need be furnished with corresponding large-scale paddy rice drying unit, the complex structure of combine, cost is higher, and annual service time is very short, and use cost is higher, and require that higher use and maintenance technique are arranged, so only use in the fraction area.The mating power of Small machine for harvesting and drying grain in sun is a hand tractor, and long about 4 meters of its fuselage is wide about 1.2 meters.Its transmission mechanism is to a lateral movement, so before the machinery operation, must manually cut out 5 meters square vacant lots with reaping hook at every patch four jiaos, and the edge of a field rand also must manually slice off simultaneously, and machine could revolve around the center, field and cut like this, pounces on to a side and puts.When running into some irregularity plot, just can not carry out operation.Though operating efficiency increases, fundamentally do not solve the problem of mechanized harvest.Because Machine Design is complicated, and use cost is higher, fault is more, transports very inconvenient simultaneously.The above-mentioned deficiency of combine and Small machine for harvesting and drying grain in sun has influenced the development of paddy rice harvesting machineryization.In the graden machine of near field, the backpack brush saw that uses adopts the backpack power set at present, drives flat rotating blade by transmission mechanism, and it is comparatively convenient to mow, but because the grass of cutting off all is placement at random, so this machinery can not be directly used in the harvesting paddy rice.

The purpose of this utility model provides a kind of portable rice harvester, and its light portable adapts to the harvesting in various plot, and its efficiency far is higher than manual reaping hook harvesting.

The technical solution adopted in the utility model is: portable rice harvester comprises bears frame, engine, clutch, transmission device and equipment, engine is installed bearing on the frame, the engine spindle nose connects transmission device through clutch, transmission device connects equipment, equipment is that a control stick front end has rotating blade, and a U-shaped baffle plate is arranged on rotating blade.

The utility model has overcome the deficiency of combine and Small machine for harvesting and drying grain in sun, and fuselage is lighter, and only about 10 kilograms, the operator bears and gets final product.Production efficiency is more than 10 times of artificial reaping hook harvesting.Frame for movement is simple, easy to operate, easy-maintaining, and fault rate is low, and use cost is low, carries easily, and is light flexibly, applied widely.

Further specify structure of the present utility model below in conjunction with drawings and embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model U-shaped baffle plate and fixed mount thereof;

Fig. 3 is that the utility model U-shaped baffle plate is at installation site, blade top schematic diagram.

Portable rice harvester is to improve to form on the basis of existing backpack brush saw, the energy of engine 2 can use heat energy or electric power, embodiment uses two-stroke gasoline engine to be power, it between gasoline engine and the transmission device automatic centrifugal clutch 3, the active body of clutch 3 links to each other with gasoline engine, the clutch block of active body produces centrifugal force when petrol engine rotational speed reaches clutch 3 in conjunction with rotating speed, overcoming spring force outwards gets rid of and is combined by kinetoplast, the power of gasoline engine is spread out of by transmission device, drives the blade of equipment.Equipment is made of action bars 6, blade 9 and U-shaped baffle plate 8.Protective cover 7 and handgrip 5 are arranged on the control stick 6, and it is connected on clutch 3 shells by flexible pipe 4, and transmission device is to drive blade 9 rotations by the flexible axle in flexible pipe 4 and the control stick 6 and through the bevel gear of control stick 6 front ends; In the bottom of U-shaped baffle plate 8 recess 10 is arranged, it cooperates as Fig. 3 with bevel gear shell 11, blade 9 and apart about 5 centimetres of U-shaped baffle plate 8 bottoms, and U-shaped baffle plate 8 is the devices that base plate arranged and partly enclose the shape sidewall, its base plate has the swallow-tail form opening in the sidewall opening direction.U-shaped baffle plate 8 is fastened on the control stick 6 by fixed mount 12, and fixed mount 12 is made of upper and lower clamping plate, and upper and lower clamping plate are fixed on U type baffle plate 8 sides, and it is fastening to reclamp control stick 6 usefulness screws.During work, the operator will bear frame and back on the body, oiling makes engine rotation, drives the actuator drives blade and rotates very fast, and rice is cut off, the rice of cutting off is under the U-shaped baffle effect, the state of can temporarily being kept upright, the operator grasps handgrip is swept to same direction and is cut simultaneously, after cutting full rice in the U-shaped baffle plate, stack to a side, promptly finish a working cycles.
