Description

The general harvest machinery of wheat rice

Technical field

But the utility model relates to a kind of not only harvest wheat but also can gather in the crops the general purpose combined harvester and thresher of rice.

Background technology

Known combine has two classes, and the first kind is that the America and Europe is traditional always, for example 1042 types (series) product produced jointly of series type such as former Beijing 2.5 types of producing the fifties in last century " Su Yuan " and existing " good " and U.S. Deere ﹠ Co..Sheller unit that its main body thresher mainly is made up of, drum with rasp bars and corresponding grid concave plate and key formula thereafter be by the wormwood artemisia separator, with and under clean, composition such as rethresher device.This machine complex structure is made difficulty, and common mechanical producer does not have technical conditions production.Grain decreases greatly (total damage＞5%), energy consumption, material consumption, cost height, uncomfortable receipts rice.

Second class is homemade cutting-axial flow type combine, waits of this type No. 2 as Xinjiang.The main body thresher of this loom, the installed threshing separator of forming by a rasp bar cut flow roller and a spike-tooth axial-flow type drum and corresponding grid concave plate thereof.Be equipped with under it and clean and rethresher device etc.The characteristics of this loom are with axial flow nail tooth drum and its notch board, replace old traditional complexity key formula straw separator by wormwood artemisia and separation function, structure is simpler, general local producer can produce.But aspects such as complete machine performance, reliability are relatively poor, and the Ministry of Agriculture and national quality testing department are united actual measurement, fault-free only 8.4 hours (rower 50 hours).Especially incompatible low stubble harvesting, because long straw easily twines stifled spike-tooth axial-flow type drum, can't operation.And the high stub land after cutting, the peasant can't plant wholely.Therefore, in the annual results later stage, burn high stubble straw everywhere.This except that make the peasant cause damage (1 mu of straw closes about 130 yuan), and cause social effects of pollution such as serious empty dirty, boat danger.

Summary of the invention

The purpose of this utility model is to provide a kind of wheat rice general harvest machinery, and this frame for movement is simple, and is easy to manufacture, and energy consumption is low, and dependable performance adapts to low stubble harvesting.

The purpose of this utility model is achieved in that this harvest machinery comprises driver's cabin; tanker; power set; header and thresher; above the body of thresher driver's cabin is installed; tanker and power set; front-wheel and trailing wheel are installed in front and back two ends below the body respectively; the body front end is connected with header; drum with rasp bars is installed in the body; drum with rasp bars back horizontal direction is equipped with arch dental roller; below drum with rasp bars and the arch dental roller grid concave plate is installed; preceding shuttle board is installed below the grid concave plate; below sorting screen and the back shuttle board, preceding shuttle board and sorting screen screw feeder and blower fan are installed.

The utility model threshing performance〉99.9%, percentage of damage＜0.2%, carry secretly＜0.5%.Promptly total damage＜1%.Simple in structure, dependable performance.Removed the rethreshing device of multiple faults, high energy consumption, directly taken off again with multiple-roll, practical proof, effective.Speed difference theory structure guarantees that cylinder cannot twine stifledly.High bar wheat rice all adapts to low stubble harvesting.Fundamentally stopped the burning straw.Significantly energy-conservation, material-saving and reduction cost (1/4-1/3).As former Beijing-2.5 type grain header adapted 90 horsepower diesels, and adopt the utility model, production efficiency is constant, 50 horsepowers of adapteds.Practical proof, the power foot.Only this joint valency is more than 20,000 yuan, saves 300 kilograms of steel, and oil consumption descends greatly.Separate with the poor rotation of high speed, the bump that replaces old traditional straw separator separates by wormwood artemisia, and it is comfortable to make it the operation balance.Easy to manufacture, be fit to industrialized mass.In addition: with 1 drum with rasp bars preceding, 1-3 arch dental roller after, and corresponding grid concave plate with known general thresher architecture combined, can be made into a general thresher of usefulness wheat rice.So-called general, be meant to change and take off Different Crop, do not need to change the threshing component, also need not the conversion drum rotation speed, every performance indications can both reach the rower requirement.

Embodiment

In Fig. 1, driver's cabin 4, tanker 5 and power set 7 are installed above the body 2 of thresher.Front-wheel 16 and trailing wheel 11 are installed in front and back two ends below the body 2 respectively, and front-wheel 16 is a driving wheel.Body 2 front ends are connected with header 1.Drum with rasp bars 3 is installed in the body 2, and drum with rasp bars 3 back horizontal directions are equipped with arch dental roller 8, grid concave plate 9 are installed below drum with rasp bars 3 and the arch dental roller 8.Shuttle board 15, sorting screen 12 and back shuttle board 10 before being equipped with below the grid concave plate 9.Below preceding shuttle board 15 and the sorting screen 12 screw feeder 13 and blower fan 14 are installed.

Drum with rasp bars 3 is 1, forms the poor threshing of high speed with arch dental roller 8 thereafter and separates portion's section, and arch dental roller 8 is 5 (or 6 to 7), and rotating speed increases one by one from front to back.Cylindrical shell is that 1.5 millimeters coil sheets are welded into.The bow tooth is an I type threshing tooth.For avoiding blowing damage, back shuttle board 10 is housed for 9 times at back two grid concave plates.Because arch dental roller 8 linear speeds progressively increase, so crop just can be unblocked in the threshing process.Promptly on the appropriate design of theory structure, guarantee the good trafficability characteristic of crop, add and removed ad hoc rethresher device, thereby guarantee the high reliability of operation.Because of removing its conventional traditional structure complicated huge straw separator device and rethresher, can reduce by 0.6 meter than the body upper of former Beijing-2.5 type, tail can shorten about 1.5 meters, makes the compact attractive in appearance and material-saving of complete machine.

In Fig. 2, three Type B Composite Triangular band L1 connect extension power, and triangle sheave 2-1 and middle speed change sheave 2-3 control its combination and tensioning by clutch regulating wheel 2-2.In driver's cabin, handle relevant control stick by operator, make clutch regulating wheel 2-2 upper and lower displacement, thereby unclamp or compress Composite Triangular band L1, realize its clutch tensioning.The outside of middle drive 2-4 drives drum with rasp bars wheel 2-5 by two C type V-belt L2, and interior two grooves drive second arch dental roller wheel 2-7, the 3rd arch dental roller wheel 2-8, the 4th arch dental roller wheel 2-9 and the 5th arch dental roller wheel 2-10 by two C type V-belt L4.Drum with rasp bars wheel 2-5 inner side slot drives first arch dental roller wheel 2-6 by two C type V-belt L3.Other drives breast wheel 2-14 through the 3rd arch dental roller wheel 2-8 inside groove by V-belt L5, drive impeller of blower 2-11 by breast wheel 2-14 again, and the left side of middle wheel shaft (dotted line) is equipped with triangle sheave 13, V-belt L6 is housed drives the auger grain elevator wheel 2-12 that holds concurrently.Other ceding of Taiwan, shuttle board, the transmission of screen box, hydraulic means and walking is identical with known grain header.
