Abstract

The utility model belongs to agricultural machinery, in particular to a miniature harvester suitable for rural families. The miniature harvester comprises an armrest, a main frame, bearing wheels, a protective box, a gear system, a work blade and a straw baffle. When in work, the miniature harvester is manually pushed, the rotation of a left wheel drives the gear system to rotate so as to drive the blade to rotate and further cut straw. The utility model has the advantages of high efficiency, no pollution, flexibility, portability and convenient transportation.

Description

Small harvester

Technical field

The utility model belongs to agricultural machinery, a kind of small harvester tool that is applicable to rural households, and especially a kind of is the small harvester of power source with the suffered frictional force of left bogie wheel.

Background technology

The rural area is most of at present adopts manual reaping hook to gather in, large-scale farm and the external large-sized power agricultural machinery that adopts.Manual reaping hook shortcoming: labour intensity is big, efficient is low, uses health to be easy to fatigue for a long time, for a long time easily suffers from some diseases service time.Existing commercially available large-scale grain header has following shortcoming: bulky, and structure and complicated operation, the transportation difficulty expends the energy, and price and consumptive material costliness to the bad adaptability of different regions landform, also are unsuitable for the harvesting in the fritter field under the existing system of China.Can not use for common peasant household buys based on above reason.

Summary of the invention

The purpose of this utility model is to improve shortcoming and the drawback of being mentioned in the appeal content, propose a kind of convenience, comfortable, efficient is high, applicability is strong, salable small harvester.Thereby, improve remote countryside area productivity for alleviating the work burden of vast farmers.

The utility model is made up of main frame (18), guard box (19), arm-rest frame cross bar (1) (11), revolver (2), vertical angular wheel (3), horizontal angular wheel (4), big column gear (5), small cylinder gear (6), knife section (7), fixed blade (14), the parallel stock of arm-rest frame (8) (9), arm-rest frame stretching structure (12), standby bar (13), knife section (7), fixed blade (14), screw (17), U-shaped pin (15), baffle plate (16) etc.

Finishing the concrete technical measures that the foregoing invention purpose taked is: a kind of small harvester by handrail, main frame, load-carrying wheel, guard box, gear train, working blade, stalk baffle plate totally six parts form.Should make machinery be more suitable for human body according to user self height and inclination angle and length that the cutting part of crop is regulated handrail before using, more comfortable during use.Operation power is provided by manpower, when the integral body of small harvester travels forward, by the rotation of revolver (2) drive with its vertical angular wheel (3) that directly links to each other thus rotation drive the rotation of horizontal angular wheel (4), horizontal angular wheel with big column gear (5) above it thus link to each other in the middle of making small cylinder gear (6) thus rotate and drive blade (7) rotation, knife section is with certain speed cutting stalk, if stalk relatively is difficult for cutting off, then can be passive blade promote several centimetres distance and lean against on the fixed blade blade (14), during two blade actings in conjunction, its operation principle is similar to scissors, can stalk be cut off agilely.After cutting off, U-shaped pin (15) on the passive blade of stalk meeting is dished out with certain speed and direction, because the variation when work of the height of grain header and speed is little, so the direction position that stalk lands is very regular, be convenient to like this its arrangement, when stalk can not fly enough far to fall on the grain header when if speed was not enough, baffle plate (16) can be pushed stalk on one side, prevents that stalk from hindering the grain header action.Guard box (19) can prevent in the crack of foreign material heave in gear and produce bigger resistance, and its weight can increase the frictional force on wheel and ground again, when the more sturdy crop of harvesting stronger power can be arranged.The angular speed of horizontal angular wheel and vertical angular wheel is than being a value, and the angular speed of small cylinder gear and big column gear is than being the b value.A〉1, b〉1, the ratio of blade angular speed and revolver angular speed is a*b, a*b is different much larger than small harvester a, the b value of 1. different models, non-concrete numerical value.

The utility model has changed the posture of people when work, and comfortable just as the walking exercise when making the people be operated in work, specific efficiency has increased several times with gathering in mutually by hand, and does not use fossil energy, and is pollution-free, is convenient to transportation flexibly.This grain header can produce very big moment when work, can be to cut off the stalk of more solid crops such as corn and Chinese sorghum, because the utility model can be produced the product of different model, its crop species that can gather in is more, and applicability is strong.
