Description

Tractor

Technical field

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

Background technology

After crops harvesting, can in field, leave a large amount of stalks and root stubble, in the time that tractor-ploughing is carried out in field, if do not disposed these stalks, tractor-hitched farm machinery will be wound around and hinder the carrying out of tractor-ploughing in when work, particularly in the time that sugarcane field carries out tractor-ploughing, because the length of sugarcane top is longer, more easily be involved in farm machinery, and affect operation effectiveness.Existing way normally adopts open incineration sugarcane top, so not only pollute the environment, and have major safety risks, and more than before tractor-ploughing collect and process operation, waste time and energy.

Summary of the invention

The object of this invention is to provide a kind of tractor, this tractor can solve the difficult problem with wasting time and energy of sugarcane top processing of staying field.

In order to address the above problem, the technical solution used in the present invention is: this tractor is provided with and cuts leaf device at its front end, the described leaf device of cutting is hinged by many lift arms and described tractor, between described lift arm, be connected with buttress brace, the described leaf device of cutting comprises bracing frame, the cutter shaft being rotated by fluid motor-driven, interval is arranged on the much knives tool on described cutter shaft, described tractor is provided with two hydraulic jacks that are obliquely installed for shearing device described in lifting, described hydraulic jack and described hydraulic motor are connected with a hydraulic pump by oil pipe respectively, on described oil pipe, magnetic valve is installed.

In the technical scheme of above-mentioned tractor, technical scheme can also be more specifically: 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 two described hydraulic jacks set up the both sides of the described Connection Block in the middle of being positioned at separately.

Further, 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.

Further, 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 cutter is cutting disc.

Further, the periphery of described cutting disc is laid with triangle blade.

Further, described triangle blade is provided with sawtooth.

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

1, 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, there are again the farm machinery of tractor rear end traction to carry out tractor-ploughing, reduce the obstruction of sugarcane top or be wound around farm machinery, make also Tian Gengjia of hack, sugarcane top, moreover because Qie Ye and tractor-ploughing can be carried out simultaneously, the number of times of manipulation back and forth while having simplified like this tractor-ploughing, improve operating efficiency, further alleviated driver's fatigue strength.

2, by fluid motor-driven, can realize speed change, bending moment, interruption transmission of power, outputting power is strong, owing to adopting hydraulic pressure transfer power, the excursion that has expanded the torque and rotational speed of power output to adapt to different operating modes, makes engine preferably under operating mode, work simultaneously; Interrupt transmission of power, can make to cut leaf device and quit work, can make like this car load not be affected in road driving, temporarily parking and field adjustment; Thereby hydraulic jack can regulate the height of cutting leaf device to carry out the real-time adjustment of depth of implements, improve and cut the adaptability of leaf device for different soil.

3, the power of engine passes to cutter shaft through transfer case, gear pump, hydraulic motor, makes cutter shaft obtain larger moment of torsion, is conducive to improve and cuts leaf effect.

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

Embodiment

Below in conjunction with accompanying drawing embodiment, the invention will be further described:

The front end of the tractor 90 shown in Fig. 1 and Fig. 2 is provided with cuts leaf device 10, this is cut leaf device 10 and comprises that bracing frame, cutter shaft 11 and interval are arranged on the much knives tool 12 on cutter shaft 11, bracing frame has a crossbeam 13, on crossbeam 13, be fixed with three equidistant Connection Blocks 14 that arrange, cutter shaft 11 and three Connection Blocks 14 are hinged, and each between adjacent two Connection Blocks 14 on cutter shaft 11 three cutters 12 are equidistantly installed; On crossbeam 13, be fixed with two just right montants 16, on every montant 16, be all hinged with two lift arms 20, on the holder 91 that is articulated with tractor 90 front ends of the other end of each lift arm 20, above two lift arms 20 between be connected with two buttress braces 21, be positioned at below two lift arm 20 outsides be connected by bending bar 15 respectively with the two ends of crossbeam 13; Tractor 90 is provided with two hydraulic jacks that are obliquely installed 30 for lifting shearing device, two hydraulic jacks 30 set up the both sides of the Connection Block in the middle of being positioned at separately, the external part of hydraulic jack 30 is connected with the lift arm of below, the other end is fixed on the holder 91 of tractor 90 front ends, the hydraulic motor 40 that drives cutter shaft 11 to rotate is installed on a Connection Block 14 in outside, referring to Fig. 3; The engine of tractor 90 by transfer gear 80 by power distribution to running gear, rearmounted farm machinery and the preposition leaf device 10 of cutting, the output of engine is by the be in transmission connection input of gear pump 70 of transfer gear 80, the output of gear pump 70 is communicated with hydraulic motor 40 and two hydraulic jacks 30 by oil pipe 50 respectively, on each oil pipe 50, be provided with corresponding magnetic valve 60, control being synchronized with the movement and the speed change of hydraulic motor 40 etc. of two hydraulic jacks 30.Cutter 12 in the present embodiment is cutting disc, is laid with the triangle blade 121 with sawtooth in the periphery of cutting disc, and cutting disc and cutter shaft 11 are perpendicular; Cutter 12 in other embodiment can be the oblique cutter of cutting type or the horizontal cutter of cutting type.

When work, engine by tractor 90 provides power, the power driven gear pump 70 distributing through transfer case 80, magnetic valve 60 is controlled hydraulic motor 40 and is with movable arbor 11 to rotate, make cutter 12 rotations cut off the sugarcane top in field, care in the time that tractor side's after 90s farm machinery pass through the route of front end-grain cutting leaf device 10, can directly carry out tractor-ploughing operation, the sugarcane top being prescinded is less on the impact of farm machinery operation, process and tractor-ploughing operation thereby make tractor 90 can synchronously carry out sugarcane top, improve operating efficiency; In operation process, can control hydraulic jack 30 by magnetic valve 60 and promote or reduce and cut leaf device 10.
