Multifunction windrower

Abstract

A multifunction windrower is characterized in that a rack is provided with a cutting table at the front end, an engine at the rear end and a gearbox in the middle; a power input shaft, a cutting table input shaft, an intermediate shaft and an output shaft are borne on the body of the gearbox by bearings; an input pinion is sleeved on the power input shaft; a shift gear is installed on the cutting table input shaft correspondingly; a first drive pinion on the cutting table input shaft is meshed with a drive gearwheel on the intermediate shaft; a second drive pinion on the intermediate shaft is meshed with an output gear on the output shaft by an idle gear drive mechanism; and a traveling wheel is installed on the output shaft; an armrest support is fixed at the top of the body of the gearbox and the top of the armrest support is connected with left and right armrest frames. The invention can be used as the windrower or as a micro-tilling machine, solves the problem of reversing during field operation, is complete in functions, convenient to use, high in utilization ratio of equipment, labor-saving in operation and safe, and has the characteristics of small volume, light weight, simple structure, easy removal and installation, convenient maintenance, economy, applicability and the like.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a multifunctional windrower. Background technique [0002] At present, with the widespread use of agricultural machinery such as cultivators, seeders, transplanters, and harvesters, the mechanization level of agricultural production in our country has been greatly improved. The windrower is a special machine for harvesting crops such as rice and wheat, and is widely used in mountainous and hilly areas. Existing windrowers are generally composed of frame, walking wheels, header, gearbox, engine and handrail frame, etc. The existing deficiencies are: [0003] 1. There is no reverse gear, and the windrower is very inconvenient to operate; at the same time, the function is single, and it can only be used when rice and wheat are harvested. The equipment is idle for a long time during slack, and the utilization rate is not high. [0004] 2. The armrest frame is generally directly fixed on t...

AI Technical Summary

Problems solved by technology

[0003] 1. There is no reverse gear, and the windrower is very inconvenient to operate; at the same time, the function is single, and it can only be used when rice and wheat are harvested. The equipment is idle for a long time during slack, and the utilization rate is not high

[0004] 2. The armrest frame is generally directly fixed on the frame, and cannot be adjusted according to users of different heights, and the operation is more inconvenient

[0005] 3. Since the power of the engine is transmitted to the output gear on the output shaft through the gear transmission mechanism in the transmission box, the load on the output shaft is large, and it takes a lot of force to reverse the running wheel when turning. On the one hand, the operation is laborious and labor-intensive. The strength is high. On the other hand, the reliability of the steering operation is poor, and the operator is prone to fall due to excessive force when turning, which poses a serious safety hazard.

[0006] 4. The header is generally equipped with two sets of independent mechanisms to realize the harvesting and delivery of crops such as rice and wheat, which is not only complicated in structure, difficult in assembly, troublesome in maintenance, but also increases the production cost of the whole machine

In addition, the linkage between the two sets of mechanisms is poor, and it is prone to situations such as out-of-synchronization between harvesting and delivery. During the harvesting operation, it is necessary to stop midway for debugging, which not only brings unnecessary trouble to the operator, but also greatly reduces the harvesting time. efficiency
