Abstract

An electric rotary tiller includes a motor, a speed reducer, a transmission shaft, a machine frame and a resistance shovel. The utility model is characterized in that: the machine frame is fixedly connected with the speed reducer box, and the speed reducer box is provided with a meshed cone shape gear pair. The small cone shape gear pair and the transmission shaft is connected with the motor, and the large cone shape gear pair and the key shaft is connected with the transmission shaft. The machine frame is connected rotarily with the wheel frame with a walking wheel, and the machine frame is installed with an elastic positioning pin shaft which can stop the wheel frame. The inner end of the elastic positioning pin shaft contacts with top plate with a rotary handle. The utility model takes advantages that: the motor substitutes with the diesel engine or gasoline engine, and the utility model has simplified structure, reduced weight, and is convenient for operation without noise and harm air to exhaust, at the same time, reducing the loss of the transmission and conduction of the same shaft.

Description

Electronic rotovator

The utility model is a kind of tillage machinery, is applicable to that various greenhouses, booth or orchard carry out rotary tillage, tillage operation.

Along with the quickening of agricultural industrialization, modernization, industrialized agriculture production has obtained fast development.Because the existing tillage machinery that is used for protection ground productions such as greenhouse, booth generally adopts diesel engine or gasoline engine as power, they exist, and volume is big, noise is high, discharge of noxious gases, drawbacks such as contaminated environment.

The purpose of this utility model is to overcome the shortcoming that above-mentioned tillage machinery exists in greenhouse or booth work, replaces diesel engine or gasoline engine with electromotor, thus make the rotovator compact conformation, small and exquisite, be convenient to operation, there is not exhaust pollution etc. in noiseless.Thereby it is increase work efficiency, reduce cost, and safe and reliable.

The purpose of this utility model is achieved in that it comprises electromotor, reduction box, power transmission shaft, frame, resistance shovel etc.It is characterized in that: affixed reduction box on frame, the bevel-gear sett of engagement is set in the reduction box, the coaxial driving coupling motor of bevel pinion wherein, the big coaxial key connecting power transmission shaft of angular wheel, on frame, rotate and connect wheeled wheel carrier, on the frame assembling can stop the elastic positioning pin axle of wheel carrier, the taking over a business of the inner contact zones swing handle of elastic positioning pin axle.

The utlity model has following advantage: after electromotor replaces diesel engine or gasoline engine, designs simplification, weight saving, small and exquisite, be convenient to handle, noiseless, no noxious gas emission, simultaneously, because coaxial conduction reduces loss, the corresponding moment of torsion that increased by the resistance shovel, can arbitrarily be adjusted the tilling depth degree.The farming convenient transfer that finishes.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a torque drive part schematic diagram of the present utility model.

Fig. 3 is that road wheel of the present utility model is regulated the part schematic diagram.

Fig. 4 is an elastic positioning pin part-structure schematic diagram.

See Fig. 1-4, concrete structure is as follows: cable 2-end joins with power supply, and the other end is taken over control earth leakage protective device 4; Electricity-leakage-proof protectors 4 connects press button 1 again, is connected with motor 5 then;

Motor

5 and 6 coaxial connections of reduction box are fixed on the frame 3 then; See Fig. 2, the bevel pinion 12 in the reduction box 6 is by

flat key

13 and 5 coaxial connections of motor, and the other end meshes with big angular wheel 11; Big angular wheel 11 and power transmission shaft 7 key connecting; Power transmission shaft 7 and rotary blade 8 pin joints that are fixed on the axle sleeve; See Fig. 3,4, the wheel carrier 19 of band road wheel 10 is rotatably connected in the two ends of frame 3, and wheel carrier is locked in horizontal level or upright position by left and right two

bearing pins

16,17 on the frame 3.Its structure is, assembling makes the spring 15 of its indentation on the

bearing pin

16,17, that rotates connection band swing handle 14 on frame 3 takes over a business 18, take over a business 18 and be flat-shaped, go to the inner of withstanding bearing

16,17 when horizontal, make bearing pin overhanging, have positioning hole corresponding on wheel carrier 19, bearing pin inserts and makes wheel carrier 19 location.

Claims

1, a kind of electronic rotovator, it comprises electromotor, reduction box, power transmission shaft, frame, resistance shovels etc. is characterized in that: affixed reduction box on frame, the bevel-gear sett of engagement is set in the reduction box, the coaxial driving coupling motor of bevel pinion wherein, the big coaxial key connecting power transmission shaft of angular wheel rotates the wheeled wheel carrier of connection on frame, on the frame assembling can stop the elastic positioning pin axle of wheel carrier, the taking over a business of the inner contact zones swing handle of elastic positioning pin axle.
