Abstract

The utility model relates to a multifunctional miniature harvester, which is composed of a decelerating transmission mechanism (13), a travelling mechanism (18), a harvesting mechanism (12), an operating handrail (16), and an actuating unit (1) installed on a machine frame (15). The decelerating transmission mechanism adopts a worm gear and a worm rod driving mode with greater speed change. The other end of the worm rod is connected with a power takeoff driving-wheel assembly (9). The utility model has the advantages of simple structure, miniaturization, low cost, stable performance, one machine with multifunction, etc., and the multifunctional miniature harvester is widely suitable for extensive rural areas.

Description

The multifunction micro grain header

The utility model belongs to agricultural machinery technological field, particularly a kind of small harvester.

Existing small harvester mainly contains two classes.One class is a power split small harvester, and another kind of is power one small harvester (claiming miniature harvester again).Power split small harvester itself is unpowered, by fraction horsepower diesel engine or hand tractor as the supporting use of external power, be characterized in that power section is as a separate component, in grain header time spent not, can independently finish other functions, realize that himself is worth, its shortcoming is big, the bad adaptability of price height, weight, and operating condition is required harsh.Power one small harvester is self-powered, has the lightweight characteristics of compact conformation, but power specially joins, and in grain header time spent not, its power section is idle, and function is very single.In addition, the more important thing is the total deficiency that above-mentioned two class small harvesters exist, be multi-stage gear deceleration or sprocket wheel deceleration transmission with the speed reducing transmission case that power links exactly, not only structure is complicated, and unload chain, chain rupture easily, the many deficiencies of fault when existing harvesting.

The purpose of this utility model is exactly to develop a kind of power one multifunction micro grain header of stable performance at above-mentioned situation.

The utility model is by the actuating unit 1 that is installed on the frame 15, reduction gearing mechanism 13, and running gear 18 and harvesting mechanism 12, operation handrail 16 is formed.Reduction gearing mechanism is by multistart worm axle 8, realize that with the multistart worm axle driving shaft worm gear be in transmission connection and clutch assembly 4 and ceding of Taiwan transmission worm gear and clutch assembly 10 are formed, and drive 2 realizations of installing on drive 3 that the multistart worm axle is installed by the one end and the actuating unit output shaft are in transmission connection; Running gear is made up of the driving wheel 18 of live axle 19, bearing block and the installation of live axle two ends and the drive 7 that middle-end is installed, and driving shaft worm gear in drive 7 and the reduction gearing mechanism and clutch assembly 4 are realized being in transmission connection; Harvesting mechanism by drive 19, be installed in 19 of drives and go up send the standing grain conveyer belt assembly 11 and the cutting bed assemblies 12 of different parts and is formed, ceding of Taiwan transmission worm gear in drive 19 and the reduction gearing mechanism and 10 realizations of clutch assembly are in transmission connection.

In order to make grain header can bring into play the effect of actuating unit season in non-harvesting, realize multi-functional machine, the utility model can connect an outputting power driving wheel assembly 9 at the end in addition of multistart worm axle.

The multifunction micro grain header that utilizes the utility model to make, owing to select the power one for use, and reduction gearing mechanism is selected the bigger worm and gear transmission of gear ratio for use, microminiaturization not only simple in structure, with low cost, and stable performance can realize multiple function, has very wide application prospect.

The utility model is further introduced below in conjunction with the accompanying drawing illustrated embodiment.Accompanying drawing (one) is the transmission schematic diagram of present embodiment, and accompanying drawing (two) is the structural representation of present embodiment.Actuating unit 1 is selected petrol engine for use, and drive 2 is selected little garden stud wheel for use, and drive 3 is selected big garden stud wheel for use, and drive 7 is selected hinge wheel for use, and it is the standing header of 600～750mm that drive 19 selects for use the ceding of Taiwan in the belt pulley cutting bed assembly 12 to select swath for use.Thereby petrol engine 1 drives 3 rotations of big garden stud wheel by little garden stud wheel 2 and makes 8 rotations of multistart worm axle during work, this moment is if driving shaft worm gear and clutch assembly 4 and ceding of Taiwan transmission worm gear and clutch assembly 10 close, then power source drives driving wheel 5 walkings by hinge wheel 7 respectively, drive by belt pulley 9 and to send standing grain conveyer belt assembly 11 and cutting bed 12 to gather in, outputting power driving wheel assembly then allows its idle running; If driving shaft worm gear and clutch assembly 4 separate with ceding of Taiwan transmission worm gear and clutch assembly 10, then the exportable power of outputting power driving wheel assembly is realized other function.

13 is deceleration box in the accompanying drawing (), and 17 is separating assembly.
