Abstract
Provided is a transmission device of an electric rotocultivator, which is used for agriculture cultivation machines. The transmission device of an electric rotocultivator comprises a motor, a shaft coupling, a side edge gear case, a rack, a knife roll, etc. Transmission parts like a gear shaft, a gear and others are disposed in the side edge gear case. When the transmission device is in work, the motor transmits power to the gear shaft, the gear and others through the shaft coupling, and drives a knife roll shaft to rotate, achieving decelerated motion. The transmission device of an electric rotocultivator is characterized in that the reduction ratio of the transmission device is quite large, and the radius of the transmitted gear is quite small, and thereby a coulter can have the maximum soil-cutting depth when the revolving radius is fixed; transmission rout lies at the side edge, preventing the problem of cultivation missing during the transmission; the fixed position of the motor is not limited, and thereby the balance problem of the weight of the total device can be resolved. The transmission device of an electric rotocultivator is simple and compact in structure, reliable in transmission, good in reduction ratio, and obvious in energy-saving effect.
Description
Technical field
The utility model belongs to a kind of agricultural machinery, particularly a kind of electronic rotovator that is applicable to farming in the booth.
Background technology
Along with the fast development of China's industrialized agriculture, the pattern of booth and chamber planting is more and more.Use tractor drive rotovator or turnplow farming meeting in the canopy chamber to cause exhaust pollution and operation inconvenience.In order to address this problem, the electronic rotovator and the patent thereof of many forms appearred in recent years, as: 03214204.8 (patent No., down together) miniature electric rotovator; 201020231995.x electronic rotovator; 200820011701.5 miniature electric rotovator; 01241718.1 electronic rotovator; 200820090544.1 electronic rotovator; 200720190864.X miniature electric rotovator etc.But all there is certain deficiency in the structure of these rotovators, as: 03214204.8 adopts the worm and gear transmission, and rotor can influence tilling depth with worm gear is coaxial, if the increased blade radius of turn then increases energy consumption; 200820011701.5 adopt middle transmission to have the problem of balking with 201020231995.x; 99248343.3 directly connect electromotor and tool roller axis with the sprocket wheel chain, it is not enough to slow down; 01241718.1 adopt bevel-gear sett to slow down, gear wheel and the coaxial tilling depth that influences of rotor, and adopted middle transmission also to have the problem of balking.Adopt middle transmission to have the way to solve the problem of balking about rotovator; Normally below transmission case, increase resistance shovel (or claiming little turnplow); This is feasible on the rotovator that tractor drives; Because moving ahead of tractor rotovator is main by tractor-drawn, and moving ahead of electronic rotovator walked when mainly revolving soil by blade certainly, moves ahead if use the resistance shovel to hinder.In order to improve the performance that moves ahead of electronic rotovator, on the 2000720093645.X patent, be provided with a land wheel drive motors and decelerator specially, this has increased the complexity of structure.
Summary of the invention
The utility model provides a kind of side gear drive deceleration device, and simple and compact for structure, the rotor turning radius is little; Good energy-conserving effect does not influence tilling depth, does not have the problem of balking; There is not the complete machine imbalance problem in electricity, can satisfy the transmission requirement of electronic rotovator preferably.
Technique scheme is achieved in that motor is fixed on the frame, links with the gear shaft of shaft coupling with motor and reduction box.2 grades of gear drives are arranged in the reduction box, and first order gear is reduced to rotary tillage rotating speed or close rotary tillage rotating speed with rotating speed of motor; Second level gear changes the position of rotor, to increase tilling depth.Reduction box places a side of rotovator, has solved the problem of balking that middle transmission exists.Reach the machine gravity balance after the gear shaft length of reduction box can be sent a telegraph machine and frame is connected, its gear shaft length is according to the requirement design of motor fixing back assembled machine balance on frame.
The advantage of the utility model: the one, simple and compact for structure, reliable transmission; The 2nd, speed reducing ratio puts in place, can make the tool roller axis rotating speed reach optimum state; The 3rd, the rotor tooth radius is little, under specified tilling depth condition, can dwindle the turning radius of rotary blade, energy efficient.The 4th, solved the problem of balking that middle transmission exists, because of electronic rotovator mainly is to lean on from walking to move ahead, then can influence the speed that moves ahead if use resistance to root out to balk; The 5th, operability is good, and the fixed position of motor is proper, and all around balance can make the operator use very easily.
Description of drawings
Fig. 1 is the utility model structural representation.Among the figure: motor 1; Shaft coupling 2; Gear shaft 3; Bearing 4; Casing 5; Frame 6; Case 7; Gear wheel 8; Travelling gear 9,10,11; Rotor 12; Rotary blade 13.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
As shown in Figure 1 is a kind of transmission structures sketch map of electronic rotovator; Mainly form by motor 1, shaft coupling 2, side gear-box 5, frame 6, case 7 and rotor 12 etc.; Frame 6 is fixedly connected with motor 1, side gear-box 5 and case 7 respectively, and driving parts such as gear shaft 3, gear wheel 8 and travelling gear 9,10,11 are housed in side gear-box 5.During work, motor 1 passes to gear shaft 3 with power through shaft coupling 2, passes to gear wheel 8 and travelling gear 9,10,11 again, and travelling gear 11 drives rotor 12 rotations to realize retarded motion.Its main points are: 1. the speed reducing ratio of this transmission device is bigger; And travelling gear 11 radiuses of final transmission are less; Make gear-box 5 less apart from the distance in rotor 12 axle center, thereby make colter 13 regularly can reach maximum depth of cut at the turning radius one near the bottom surface of ground one side.According to theory of mechanics, in order to reach energy-saving effect, under the prerequisite that guarantees depth of cut, the turning radius of colter is more little good more; 2. the route of transmission has been avoided the problem of balking at side; 3. the length of 3 of gear shafts can be convenient to solve the equilibrium problem of complete machine weight according to the fixing Position Design of motor 1.
