Abstract
The utility model relates to an agricultural rotary cultivator, which can accomplish operations of ploughing, harrowing, seeding, fertilization and the like in one step, and comprises a stand, an engine fixed on the stand, a power transmission device and a rotary tilling wheel. The power transmission device consists of two-stage belt pulleys and two-stage chain wheels, wherein a first-stage belt pulley is connected with the engine, the output of the first-stage belt pulley is connected with a second-stage belt pulley, the output of the second-stage belt pulley is connected with a first-stage chain wheel, the output of the first-stage chain wheel is connected with a second-stage chain wheel, and the output shaft of the second-stage chain wheel is fixed on the rotating shaft of the rotary tilling wheel. The utility model has smooth and steady power transmission no matter under what conditions, overcomes the defects of intense vibration of the whole machine caused by unbalanced transmission of the existing rotary tiller, prolongs the service life of the rotary tiller by more than two years, and greatly reduces the manufacture cost of the rotary tiller.
Description
Technical field
The utility model is a farm implements, particularly can once finish the agricultural rotovator of operations such as cultivated, rake, sowing, fertilising.
Background technology
Rotovator is that China the fastest advanced person of immediate development drives tillage implement, and its collection is ploughed, the rake unification, and a rotary tillage can reach the old-fashioned plow harrow effect on ground down several times, and can carry additionally other auxiliary and form rotary tillage compound operation machine.At present, using is LGN140,150, the 160 type rotovators that Co., Ltd of Nanchang Rotary Cultivator Factory produces more widely.The power drive mechanism of this series rotovator is to adopt power transmission shaft and the transmission of double Hooke's joint curve.Be equipped with small conical gear, large conical gear, two horizontal gears, three horizontal gears, four horizontal gears, knife shaft gear etc. on its power transmission shaft.By various gears and the axle transmission that cooperatively interacts, make thousands of speed of walking around of engine output, reaching hundreds of in the rotating shaft that is transferred to rotovator changes, thereby drives rotovator work.Its shortcoming is in operation process, as run into turning, reversing all must the lifting rotary tillage wheel, the angle of the universal joint of power transmission shaft in lifting and operation process is because the excessive turning cylinder that makes easily of curvilinear motion is unbalance, cause complete machine generation sharp pounding, thereby be easy to quicken the phenomenon of the part generation sharp pounding of rotary tillage wheel and complete machine, thereby comparatively fast cause the damage of complete machine and parts.In addition, owing on the above-mentioned rotovator power transmission shaft a lot of groups of gears are set, the gear-box cost is higher, thereby improves the cost of rotovator.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of when the bigger variation of angle generation of power transmission shaft in the lifting process is taken turns in rotary tillage, complete machine but can be steadily, normal operation work, the agricultural rotovator that can not shake, corresponding complete machine and the parts avoided reduce the rotovator cost simultaneously because of shaking too fast fatigue damage.
Solution of the present utility model is: a kind of agricultural rotovator, comprise frame, be fixed on the engine on the frame, actuating unit and rotary tillage wheel is characterized in that actuating unit is made of two-stage belt pulley and double stage chain wheel, sending and receiving motivation output shaft be first order belt pulley, what connect first order belt pulley is second level belt pulley, what connect second level belt pulley is first order sprocket wheel, and what connect first order sprocket wheel is second level sprocket wheel, and the output shaft of second level sprocket wheel is fixed in the rotating shaft of rotary tillage wheel.
The engine output speed reaches thousands of commentaries on classics, by the transmission of two-stage belt pulley, by steamboat band bull wheel, thereby reduce the power rotating speed, when arriving sprocket wheel, transmission of power reduces the power rotating speed by the first order, make the output wheel of second level sprocket wheel drive the rotating shaft rotation of rotary tillage wheel at last, thereby drive the rotation of rotary tillage wheel, the rotary blade work that rotary tillage is taken turns on it realizes agricultural rotary tillage operation.Adopting the double stage chain wheel transmission, is that transfer motion power weakens to some extent when arriving the sprocket wheel place owing to power transmission on the one hand, so must adopt positive drive, helps direction-variable power on the other hand.
In the solution of the present utility model, can be provided with belt tension mechanism at the belt place of belt pulley to guarantee the reliability of power transmission.
Advantage of the present utility model: because the utility model power transmission mechanism adopts two-stage belt pulley and double stage chain wheel transmission, no matter under which kind of situation, power transmission is all carried out in steadily, overcome existing rotovator power transmission shaft unbalance in lifting and operation process, caused the shortcoming of complete machine generation sharp pounding.Thereby avoided the quick fatigue wear of complete machine and parts, complete machine is prolonged more than 2 years service life.Simultaneously, the kind of drive that the utility model adopts reduces greatly than gear-box cost, thereby has reduced the cost of complete machine.

Fig. 1 is the utility model power transmission mode structural representation.
Embodiment
The utility model embodiment as shown in Figure 1, the actuating unit of agricultural rotovator is made of two-stage belt pulley and double stage chain wheel, the drive of its first order belt pulley is fixed on the output shaft of engine 1, the output wheel 2 of first order belt pulley is coaxial fixing with the drive of second level belt pulley 3, output wheel 2 diameters of first order belt pulley are greater than the drive of first order belt pulley, output wheel 2 diameters of first order belt pulley are greater than the drive 3 of second level belt pulley, output wheel 4 diameters of second level belt pulley are greater than the drive 3 of second level belt pulley, the output wheel 4 of second level belt pulley is coaxial fixing with the drive sprocket of first order sprocket wheel 6, on its fixed axis, be equipped with simultaneously braked wheel 5, output wheel 4 diameters of second level belt pulley are greater than the drive sprocket 6 of first order sprocket wheel, the output wheel 7 of first order sprocket wheel is fixing with wheel with the drive sprocket 8 of second level sprocket wheel, output chain gear 7 diameters of first order sprocket wheel are greater than the drive sprocket 6 of first order sprocket wheel, and the output chain gear 9 of second level sprocket wheel is fixed in the rotating shaft of rotary tillage wheel.Be the belt transmission between the belt pulleys at different levels, be the chain transmission between the sprocket wheels at different levels.The rotating shaft of rotary tillage wheel is provided with rotary blade 10, and the belt place of belt pulleys at different levels is provided with belt tension mechanism 11.
Claims (2)
1. agricultural rotovator, comprise frame, be fixed on the engine (1) on the frame, actuating unit and rotary tillage wheel (9) is characterized in that actuating unit is made of two-stage belt pulley and double stage chain wheel, sending and receiving motivation output shaft be first order belt pulley, what connect first order belt pulley is second level belt pulley, what connect second level belt pulley is first order sprocket wheel, and what connect first order sprocket wheel is second level sprocket wheel, and the output wheel of second level sprocket wheel is fixed in the rotating shaft of rotary tillage wheel (9).
