Description

Tractor

Technical field

The present invention relates to manufacture of agricultural machinery technical field, especially a kind of tractor.

Background technology

Tractor refers to for drawing, promote, carry or driving outfitting tool to carry out the self-propelled dynamic power machine of operation, it is the main tool that peasant is engaged in economic development and agro-farming operation, a kind of wheel tractor as shown in Figure 5, Figure 6, include propons, back axle and engine 102, engine 102 is connected with rear axle box 101 by gearbox, and rear axle box 101 is provided with the walking power take-off being connected with rear walking wheel drive unit, the spline output shaft 103 being connected with farm implements and exports the shaft-driven raising rod device 104 being contained in rear axle box by lifting drive.In use there is following deficiency in this tractor: 1, the power of engine outputs to rear axle box, drive the trailing wheel walking of tractor by walking power take-off, simultaneously by spline output shaft by power transmission to farm implements, because being subject to the output torque of rear axle box structural limitations spline output shaft little, a little less than power, once can only drive farm implements to carry out a kind of operation, must change farm implements and just can carry out lower step operation, can not integration of operation, operating efficiency is low; 2, the lifting of farm implements and decline drive raising rod device to realize by lifting drive output shaft, and lifting drive output shaft is one of three power take-offs of rear axle box, therefore slow the and sensitivity of the little raising rod device action that causes tractor of the normal output torque because of lifting drive output shaft is low.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of tractor with integration of operation function, and it is little that this tractor can solve existing tractor output torque, and function singleness causes the low problem of operating efficiency.

In order to address the above problem, the technical solution adopted in the present invention is: this tractor, comprise propons, back axle and raising rod device, on described propons and back axle, be provided with vehicle frame, the front end of described vehicle frame is hinged with by many lift arms of the first hydraulic jack lifting, is connected with and cuts leaf device on described lift arm; The described leaf device of cutting comprises bracing frame, and by the cutter shaft of the first fluid motor-driven rotation, interval is arranged on the much knives tool on described cutter shaft; The bridge case being in transmission connection by front power input shaft and engine is equipped with in the rear end of described vehicle frame; On described bridge case, be hinged with the second hydraulic jack that drives the lifting of described raising rod device; Described raising rod device is connected with farming support, is disposed with deep soil loosing shovel, scrapes mamoty, plough and the rotary blade by the second fluid motor-driven rotation on described farming support; Described the first hydraulic jack, the first hydraulic motor, the second hydraulic jack is connected with hydraulic pump respectively with the second hydraulic motor, and described hydraulic pump is connected with engine by transfer gear.

In technique scheme, technical scheme can also be more specifically: between described lift arm, be connected with buttress brace, described the first hydraulic jack is contained between the hanging fixing seat and described lift arm being fixedly connected with the front end of vehicle frame, support frame as described above comprises crossbeam, on described crossbeam, be fixed with three equidistant Connection Blocks that arrange, described cutter shaft and three described Connection Blocks are hinged, and have two the first hydraulic jacks, and described the first hydraulic jack sets up the both sides of the described Connection Block in the middle of being positioned at separately; On described crossbeam, be fixed with two just right montants, on every described montant, be all hinged with two described lift arms, above two described lift arms between be connected with two described buttress braces, the two lift arms outside that is positioned at below is connected by bending bar respectively with the two ends of described crossbeam; Described hydraulic pump is gear pump, and the input of described gear pump is in transmission connection by the engine output of transfer gear and described tractor.

Further: described raising rod device comprises the lifting arm that is hinged on described bridge case and by pull bar and the hinged push rod of described lifting arm, described the second hydraulic cylinder is contained between described bridge case and described push rod.

Further: on described farming support top, fertilizer storage box is housed, described fertilizer storage box is provided with the soil feed pipe extending respectively between described deep soil loosing shovel and described rotary blade and extends the plantation feed pipe at described plough rear.

Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, owing to being provided with vehicle frame on propons and back axle, the bridge case being in transmission connection by front power input shaft and engine is housed in the rear end of vehicle frame, the power of input bridge case separates transmission with the power that drives tractor walking, not only the moment of torsion of the power take-off of bridge case is large, powerful has also increased tractor overall construction intensity, make complete machine not fragile, increase the service life.

2, because the lift arm that is arranged at vehicle frame front end drives by the first hydraulic jack, the cutter shaft that Qie Ye device has is by the first fluid motor-driven, and the raising rod device that is arranged at vehicle frame rear end drives by the second hydraulic jack, be connected in rotary blade on raising rod device by the second fluid motor-driven; Owing to adopting hydraulic pressure transfer power, expand the excursion of the torque and rotational speed of power output, to adapt to different operating modes, make engine preferably under operating mode, work simultaneously; Fluid motor-driven, can realize speed change, bending moment, interruption transmission of power, and outputting power is strong, when Driven by Hydraulic Cylinder is interrupted transmission of power, can make cutter shaft and rotary blade quit work, and can make like this car load not be affected in road driving, temporarily parking and field adjustment.

3, cut leaf device because vehicle frame front end is provided with, rear end is provided with deep soil loosing shovel, rotary blade, scrapes mamoty and plough; In the time carrying out tractor-ploughing operation, can before being arranged on tractor, the sugarcane top of cutting leaf device cut-out field be set, the deep soil loosing shovel being drawn by tractor rear end again, rotary blade, scrape mamoty and plough to field deep plough, rotary tillage, smooth, start and apply fertilizer, not only reduce the obstruction of sugarcane top or be wound around farm machinery, make also Tian Gengjia of hack, sugarcane top, and disposable complete deep ploughing, rotary tillage, smooth, start and the operation of applying fertilizer; Realized the integration of operation in farmland, the number of times of manipulation back and forth while having simplified tractor-ploughing, has improved operating efficiency, has further alleviated driver's fatigue strength.

4, the structure of bracing frame and lift arm has improved the fastness of cutting leaf device.

5, because the top of farming support is provided with fertilizer storage box and the feed pipe being connected with fertilizer storage box, can realize the rear fertilising at once of deep ploughing, and by the rotary tillage of carrying out subsequently, fertilizer and soil fully be stirred, improve fertilising efficiency.
