Description

The multifunctional agricultural three-wheel vehicle

The utility model relates to and a kind ofly both can transport, but the multifunctional agricultural three-wheel vehicle of farmland operation again.

At present, most of agricultural tricycles only can be used for the communications and transportation in urban and rural highway and field.But friend peasant is badly in need of a kind of motor-driven three-wheel vehicle of multipurpose agricultural that not only can be used for transporting but also carrying out farm work, this Shijiazhuang Tracntor Factory has been produced a kind of " wishing the three-wheel king " three-wheel vehicle, but this three-wheel vehicle can not satisfy transportation and the total function of farmland operation well, promptly when agricultural machinery and implement such as supporting use rotovator, cultivated plough, only can use the walking of one shelves, speed is slow, and efficient low can not be accepted its application person.

The purpose of this utility model is improvements over the prior art, and a kind of hauling operation of both can having carried out is provided, and can satisfy the multifunctional agricultural three-wheel of farm work speed again.

The purpose of this utility model is achieved in that a kind of multifunctional agricultural three-wheel vehicle, it is mainly by vehicle frame and the diesel engine that is fitted on the vehicle frame, operation and transmission device, change speed gear box and the goods bucket composition equipped with vehicle frame, change speed gear box comprises shifter bar, variable shaft and be assemblied in variable gear on the variable shaft respectively, variable gear (11) is 38-40: 19-21 with the converter speed ratio of duplex slippage variable gear (13b), variable gear (12) is 19-21: 38-40 with the converter speed ratio of duplex slippage variable gear (13a), and variable gear (15) is 19-21: 43-45 with the converter speed ratio of variable gear (16).

The equipped traction in the rear portion of vehicle frame connecting rack, said traction connecting rack is by lift pump, lifting arm, elevator chain, coupling spindle, pull bar and strut bar are formed, the lift pump both sides respectively are provided with a lifting arm, connect with an end of elevator chain respectively on two lifting arms, the other end of its elevator chain is contained on the plunger of lift pump, the one end hinge joint of lifting arm is on frame, its other end is through coupling spindle and pull bar hinge joint, the other end of pull bar link in the upper end of the matching used farmland operation facility of three-wheel vehicle, one end of the bottom hinge joint strut bar of its farmland operation facility, the other end of strut bar connects with the back axle of three-wheel vehicle is movable.Shifter bar is horizontal shifter bar.

The technological advance that the utility model is obtained is: changed the converter speed ratio of variable gear, maximum speed can reach 40km/h, and load carrying ability is 750kg, both has been applicable to the operation in farmland, also satisfies the needs of transportation.Install the traction connecting rack additional, can use with various complete set of farm machines and tools.This three-wheel vehicle integral installation cooperates reason, and driving device is safe and reliable, and long service life is specially adapted to the processing and the communications and transportation of rotary tillage, arable land, sowing, irrigation and drainage and the agricultural byproducts of mountain area, Plain, intersected country.

Be that embodiment further describes the utility model below with the accompanying drawing:

Fig. 1 joins the structural representation of loading hopper for the utility model.

Fig. 2 is the utility model and the matching used structural representation of rotovator.

Fig. 3 is the structural representation of the utility model variable shaft and variable gear.

As Fig. 1, Fig. 2, shown in Figure 3, propulsion source diesel engine and be fitted in the front end of vehicle frame 18 by the operating mechanism that operation handlebar, variable speed operation bar, power-transfer clutch etc. are formed, change speed gear box is installed in the postmedian of vehicle frame 18.Change speed gear box is made up of five variable shafts, shifter bar and 12 variable gears, variable shaft 1-5 is installed on the change speed gear box successively, wherein the two ends of variable shaft 1 lean out change speed gear box and equipped power wheel respectively, the power wheel of one end connects with the propulsion source diesel engine through belt conveyor, and another power wheel is used for driving and the matching used farmland operation facility of three-wheel vehicle.Suit variable gear 6 on the variable shaft 1, variable gear 7,8 are sleeved on the variable shaft 2, be set with duplex slippage variable gear 9a on the variable shaft 3,9b, reverse gearwheel 10, variable gear 11 and variable gear 12, duplex slippage variable gear 13a, 13b, slippage variable gear 14 and change speed pinion 15 are set on the variable shaft 4, suit speed change big gear wheel 16 and connect gear 17 on the variable shaft 5, the transmission gear of the diff on it connects gear 17 and is installed in tricycle rear axle mesh and connect (duplex slippage variable gear 9a wherein, 9b, 13a, 13b and variable gear 14 are that slippage connects with variable shaft).In the present embodiment, variable gear 11 is 39: 19 with the converter speed ratio of duplex slippage variable gear 13b, and variable gear 12 is 20: 39 with the converter speed ratio of duplex slippage variable gear 13a, and variable gear 15 is 20: 44 with the converter speed ratio of variable gear 16.The shifter bar of change speed gear box connects with the variable speed operation bar that is located at vehicle frame 18 front ends by the speed change pull bar.Its shifter bar is horizontal shifter bar.Goods bucket 19 is assemblied in the postmedian of vehicle frame 18, and cooperates with lift pump 20, can realize automatic tipping bucket function, goods bucket 19 is a demountable structure simultaneously, go to unload goods and struggle against 19, equipped traction connecting rack on vehicle frame 18 can connect with agricultural machinery and implement (as rotovator, sower, cultivated plough etc.).The traction connecting rack is by lift pump 20, lifting arm 21, elevator chain 22, coupling spindle 23, pull bar 24 and strut bar 25 are formed, the both sides of lift pump 20 are equipped with lifting arm 21, connect with an end of elevator chain 22 is movable respectively on two lifting arms 21, the other end of elevator chain 22 is assemblied on the plunger of lift pump 20, one end of lifting arm 21 is hinged on the frame 18, its other end is hinged through coupling spindle 23 and pull bar 24, the other end of pull bar 24 is hinged on the upper end with the matching used rotovator 26 of three-wheel vehicle, one end of the hinged strut bar 25 in the bottom of rotovator 26, the other end of strut bar 25 is hinged with the coupling spindle that is fixed on the tricycle rear axle.When rotovator 26 does not carry out operation, can drive the hoisting force that elevator chain 22 makes progress for lifting arm 21 1 by lift pump 20, this power is lifted from ground through coupling spindle 23, pull bar 24 with rotovator 26, in order to guarantee that rotovator 26 breaks away from the firm balance in ground, promptly is equipped with strut bar 25 in the bottom of rotovator 26.
