Abstract
The invention discloses a four-wheel drive boat tractor with an adjustable base plate. The four-wheel drive boat tractor comprises a boat body, an engine, a front drive axle and a rear drive axle. A front driven bevel gear is arranged on the portion, inside the front drive axle, of a front wheel axle, and a rear driven bevel gear is arranged on the portion, inside the rear drive axle, of a rear wheel axle. The engine is provided with a front power output shaft and a rear power output shaft. The front power output shaft and the rear power output shaft are connected with a front gearbox power input shaft and a rear gearbox power input shaft respectively. A front gearbox power output shaft and a rear gearbox power output shaft are connected with a front driving bevel gear in the front drive axle and a rear driving bevel gear in the rear drive axle respectively. The front driving bevel gear and the rear driving bevel gear are meshed with the front driven bevel gear and the rear driven bevel gear respectively. Mechanical principles and a mechanical structure are adopted in the four-wheel drive boat tractor, and the four-wheel drive boat tractor has the advantages of being good in adaptability, easy to operate, convenient to use, high in work efficiency and the like. A four-wheel drive power system of the four-wheel drive boat tractor well solves the problems that a traditional boat tractor is insufficient in power and can not step over barriers; buoyancy can be effectively increased by lifting the movable buoyancy base plate, the boat body can be kept stable and prevented from being stranded, and therefore work efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of agricultural boat tractor, particularly relate to the adjustable boat tractor of a kind of four wheel drive and base plate.
Background technology
Modern agriculture utilization machinery is cultivated very general, and boat tractor is exactly a kind of farm machinery of often using at present, in paddy field, particularly in deep mud feet fields, ploughs, and generally will use boat tractor.Because boat tractor floats on plow layer surface by its hull taking the weight of, spoiled soil hardcore, does not especially harrow in land reclaimed from a lake and waterlogged plot intertillage, not depression, and non-slip, its superiority is quite outstanding.But existing boat tractor in farmland production process with a varied topography, often encounter be short of power cannot across obstacle situation, also can encounter that base plate is too low causes the stranded or too high hull of base plate not bubble through the water column, affect production process.
Summary of the invention
The invention provides the adjustable boat tractor of a kind of four wheel drive and base plate, with solve that existing boat tractor exists be difficult to leaping over obstacles, be short of power, the deficiency such as easily stranded, buoyancy is unstable.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of four wheel drive and base plate are adjustable boat tractor, comprise hull, engine, forward and backward drive axle, described forward and backward drive axle is equipped with respectively front-wheel wheel shaft and rear axle, in forward and backward drive axle, on front and rear wheel wheel shaft, be respectively arranged with forward and backward passive umbrella tooth; Described engine is provided with former and later two power take-offs, described forward and backward power take-off is connected with forward and backward gearbox power input shaft respectively, the power take-off of described forward and backward gearbox is connected with the forward and backward active umbrella tooth in forward and backward drive axle respectively, and described forward and backward active umbrella tooth meshes with forward and backward passive umbrella tooth respectively; Described hull bottom is provided with movable buoyancy base plate, and this activity buoyancy base plate front end is hinged at front-wheel wheel shaft place and hull bottom; The position that is positioned at rear axle top on described hull is respectively arranged with two hydraulic jacks in left and right, the push rod of this hydraulic jack is connected with the power arm of transmission levers respectively, the fulcrum of described transmission levers is arranged on rear axle, and the resistance arm of transmission levers and movable buoyancy base plate are hinged.
As preferably, the two ends of described front-wheel wheel shaft are connected with driving wheel through turning to universal joint respectively.
As preferably, the fulcrum of described transmission levers is provided with annular ring, and this annular ring is sleeved on rear axle, and take rear axle as fulcrum.
The present invention adopts novel mechanical principle and frame for movement, has adaptability good, simple to operate, easy to use, operating efficiency high.Its four wheel drive dynamical system has well solved traditional boat tractor and has been short of power, and is difficult to the problem of leaping over obstacles, by lifting activity buoyancy base plate, can effectively increase buoyancy, keeps hull stable, avoids stranded, has promoted greatly operating efficiency.

Embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.In conjunction with Fig. 2,3,4,5 known, this boat tractor comprises hull 1, engine 2, front driving wheel 300, rear drive sprocket 200, front driving axle 3 and rear driving axle 4.Wherein forward and backward drive axle 3,4 is equipped with respectively front-wheel wheel shaft 33 and rear axle 43, and the two ends of front-wheel wheel shaft 33 are connected with front driving wheel 300 through turning to universal joint 310,311 respectively.Owing to having added universal joint, two front driving wheels 300 just can freely turn to.
In forward and backward drive axle, the middle part of front and rear wheel wheel shaft 33,34 is respectively arranged with forward and backward passive umbrella tooth 32,42.Engine 2 is provided with front power take-off 21 and rear power output shaft 22, forward and backward power take-off 21,22 is connected with forward and backward gearbox power input shaft 25,26 respectively, and the power take-off 27,28 of forward and backward gearbox is connected with the forward and backward active umbrella tooth 31,41 in forward and backward drive axle 3,4 respectively.Forward and backward active umbrella tooth meshes with forward and backward passive umbrella tooth 32,42 respectively.
When the present invention works, before and after being communicated to by forward and backward gearbox 23,24, the kinetic force of engine 2 on drive axle 3,4, forms four wheel drive dynamical system, effectively strengthened the dynamic role of boat tractor, strengthened the ability of boat tractor leaping over obstacles.By hydraulic jack 6,7, coordinate the work of its transmission levers, energy adjusting activity buoyancy base plate 5 height overhead, has solved the easily unsettled problem of stranded, buoyancy of existing boat tractor, has greatly improved farming efficiency.
Finally, it should be pointed out that explained above is only the more representational example of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to the claims in the present invention, still belongs to the scope that the present invention is contained.
