Abstract

The utility model relates to a central transmission double-speed rotary cultivator which can adapt to different soils, dry lands and paddy fields and is specially used for rotary tillage operation in the fields and has two speeds, namely fast speed and slow speed, and the requirements of different operations are met. The automatic transmission is characterized in that the variable speed deflector rod is connected with a shifting gear, the shifting gear can be movably connected with a coaxial normally meshed gear, the normally meshed gear is connected with a driving sprocket through the shifting gear, a chain is connected with the driving sprocket and a driven sprocket, and the driven sprocket is connected with a cutter shaft tube; the normally meshed gear, the gear shifting gear and the driving chain wheel are arranged on the same shaft in the transmission case and can be meshed and separated with each other, so that the conversion between a fast speed and a slow speed and the conversion between a neutral gear and a neutral gear are realized.

Description

Central authorities' transmission double speed rotovator
Technical field: the utility model is a kind ofly can adapt to different soils, nonirrigated farmland and paddy field, and different work needs, and carries out the central transmission double speed rotovator rotary tillage operation, that have fast speed and slow speed specially in the field.Belong to the farm machinery field.
Background technology: before the utility model, the rotovator structure of farm work and technology have experienced an evolution, the power input mode of rotovator is by the side chain transmission type of the 1970s and 1980s, develop into the central gear driven type of the nineties middle and later periods, though this technical development improves the transmission stability of rotovator, reliability, it is reasonable that complete machine structure is tending towards, but owing to have only an operating rate, therefore, to the bad adaptability of field soil, inefficiency.Rotovator is when carrying out farm work, and fibrous root carries out rotary tillage or exempts from the situation that rotary tillage is directly carried out in ploughing after according to the resistivity situation of each piece soil and ploughing, chooses and uses different rotovator operating rates, could obtain the highest operating efficiency and favorable economic benefit.
Summary of the invention: task of the present utility model is exactly a central transmission double speed rotovator that invention is used on central driving rotary cultivator, that have two operating rates of speed (or claiming gear) and a neutral.
The utility model carries out power transmission work with following method: the main central transmission double speed rotovator of rotary blade being made of transmission case, frame, tail wheel combination, attached guard shield, well-behaved base device, left and right cutter shaft pipe and 22, the cutter shaft tube end is equipped with rotary blade, it is characterized in that the speed change driving lever is connected with power shift gear, power shift gear can flexibly connect mutually with coaxial constant mesh gear, constant mesh gear is connected with drive sprocket by change gear, chain connects drive sprocket and driven sprocket, and driven sprocket connects the cutter shaft pipe; Constant mesh gear and power shift gear are installed on the same axle in the transmission case, can be meshing with each other and separate, finish fast, at a slow speed with the conversion of neutral.
The utility model is for adapting to the different work needs in different soils and nonirrigated farmland, paddy field, on the basis of original central transmission single speed rotovator, with the hand tractor is to drive the chassis, invented the central transmission double speed rotovator of fast speed and slow speed and neutral, improve the work efficiency of rotovator operation, reduce cost greatly, reach goal of the invention.
Description of drawings: be described further below in conjunction with accompanying drawing illustrated embodiment structure.
Fig. 1 the utility model central authorities transmission double speed rotovator is installed in the schematic diagram after the combination on the Dongfeng series hand tractor.
Fig. 2 the utility model central authorities transmission double speed rotovator uses the schematic diagram of workover rig with constituting the field together;
Fig. 3 is the cutaway view of the utility model central authorities transmission double speed rotovator power transmission route.
Embodiment: with four studs (2) central transmission double speed rotovator (3) is connected in the rear portion of hand tractor gearbox (1), two alignment pins location are arranged on the composition surface, to guarantee the back-geared normal engaged of assembling.
The utility model central authorities transmission double speed rotovator is made up (7), is taken advantage of base device (8) to form by transmission case (4), frame (5), protective cover (6), tail wheel.Transmission case is a main working parts, and it is by a constant mesh gear (10), power shift gear (9), driving and driven sprocket wheel (11,14), chain (12), and rotary blade (13) is formed.Rotate by main frame gearbox meshing gear driven gear (9,10), pass through sprocket wheel (11), chain (12) again, drive sprocket wheel (14) and rotate, drive cutter shaft pipe (16) again and rotate, finally drive rotary blade (13) rotation, realize rotary tillage.
Speed change driving lever (15) is turned right and is stirred, and change gear (9) moves to the left side gear, and the power of gear box of tractor is directly delivered to sprocket wheel (11) by change gear (9), and this moment, the operating rate of rotovator was quick; Main transformer speed driving lever (15) is turned left and is stirred, and change gear (9) moves to the right side gear, and the power of gear box of tractor is delivered to change gear (9) successively by constant mesh gear (10), sprocket wheel (11), this moment rotovator operating rate at a slow speed; Speed change driving lever (15), change gear (9) are neutral gear when mediating.
Use the originally practical field rotary tillage operation of carrying out, the operating efficiency of rotovator is improved more than 40%, and make this rising 10%, have good market prospects.
1-speed changing box for walking tractor; 2-stud; 3-centralized gearing double-speed rotary tiller; 4-transmission case; 5-frame; 6-protective cover; The combination of 7-tail wheel; 8-take advantage of base device; 9-power shift gear; 10-normal engaging tooth Wheel; 11-drive sprocket; 12-chain; 13-rotary blade; 14-driven sprocket; 15-speed change driving lever; 16-The cutter shaft pipe.
