CN2383305Y - Working machine for farm field - Google Patents

Abstract

The utility model relates to a working machine for farm fields, which mainly comprises a diesel engine, a gear box, a steering handle and a single driving wheel which are arranged on a front machine frame, and two travelling wheels which are arranged at both sides of the lower part of the tail end of a back machine frame. The front end of the back machine frame is hinged with a vertical axis arranged on the front machine frame. The back machine frame is provided with a crossbeam. The crossbeam is provided with a connecting rack which can transversely move for the convenience of the connection of agricultural tools such as a ploughshare, or a fertilizer distributor, etc. The utility model is characterized in that the working machine adopts the single driving wheel, and the connection of a transverse axis does not exist between the two travelling wheels. Therefore, agricultural crops can not be influenced during the operation of intertillage period. The difference of steering does not exist in the process of running, the steering is flexible, and the linearity is favorable.

Description

Farm land cultivator

The utility model relates to a kind of farm working machinery.

At present, generally the farm working machinery of Shi Yonging mostly is two front-wheel drives, turns to be forced action type.When ridging intertillage operation, because forced steering easily forms and turns to poorly, make ridging straight line deviation big, in travelling in the climb and fall road, bad driving, careless slightly, the generation that just can bring dangerous accident.Owing to be the two-wheeled operation, little with the ground interplanar distance across the power transmission shaft of broad between the two-wheeled, during to the land for growing field crops operation of intertillage phase (this moment, crop was higher), the intertillage fertilising is difficult to realize.

At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides and a kind ofly turns to flexibly, strong, the farm land cultivator that can realize the land for growing field crops operation in the intertillage phase of linearity during farmland operation.

The purpose of this utility model is achieved in that it comprises forebay and the diesel engine that is located on the forebay, gearbox, steering handle and driving wheel, the power-take-off pulley of diesel engine and the power of gearbox are failed belt crop rotation belt transmission, chain crop rotation chain drive on the power output sprocket of gearbox and the driving wheel wheel shaft, it is characterized in that: placing the driving wheel on the forebay is single driven wheel, be positioned on the mmi machine frame single driven wheel upper end vertex directly over be provided with vertical shaft, this vertical shaft and afer bay front end are hinged, be arranged with two road wheels in both sides, the terminal bottom of afer bay, be provided with crossbeam on afer bay, this crossbeam is provided with and can laterally moves the link of being convenient to connect turnplow or fertilizer applicator.

The utility model has the advantages that: adopt single wheel drive, it is poor that nothing turns to, and draws stressed and turn to all to act on the vertical shaft, make to turn to more flexibly, linearity is stronger during farmland operation, does not have transverse axis between two road wheels, when walking to crops without any influence, be convenient to intertill operation.

Below in conjunction with accompanying drawing the utility model is explained.

Fig. 1 is the utility model structural representation.

Fig. 2 is the rearview of Fig. 1.

Fig. 3 is that the K of Fig. 1 is to view.

By accompanying drawing as can be known, diesel engine 2, gearbox 9, steering handle 4 and single driven wheel 12 all are arranged on the forebay 1, adopt belt 13 transmissions between the power input pulley of the power-take-off pulley of diesel engine 2 and gearbox 9, sprocket wheel on the power output sprocket of gearbox 9 and the single driven wheel wheel shaft adopts chain 11 transmissions, the vertical shaft 3 that is located on the forebay is hinged with the front end of afer bay 5, two road wheels 7 that are located at the afer bay both sides respectively place respectively the terminal bottom of afer bay with two live axles on, link 8 upper ends of being convenient to connect turnplow 9 are enclosed within on the crossbeam 14 that is located on the afer bay, link 8 is laterally moved on crossbeam 9, adjust the ridge distance, adjust the back and fix with bolt.The beam overall of single driven wheel is in 400mm, and crop row is apart from about 500mm, and single driven wheel has no effect to crop when walking, and the crossbeam on the afer bay, also has no effect to crop when the intertillage fertilising apart from ground 800mm.

Claims (1)

1, a kind of farm land cultivator, it comprises forebay and the diesel engine that is located on the forebay, gearbox, steering handle and driving wheel, the power-take-off pulley of diesel engine and the power of gearbox are failed belt crop rotation belt transmission, chain crop rotation chain drive on the power output sprocket of gearbox and the driving wheel wheel shaft, it is characterized in that: placing the driving wheel on the forebay is single driven wheel, be positioned on the mmi machine frame single driven wheel upper end vertex directly over be provided with vertical shaft, this vertical shaft and afer bay front end are hinged, be arranged with two road wheels in both sides, the terminal bottom of afer bay, be provided with crossbeam on afer bay, this crossbeam is provided with and can laterally moves the link of being convenient to connect turnplow or fertilizer applicator.
