Description

A kind of paddy planter special gear box

Technical field

The utility model is related to a kind of gearbox in agricultural machinery research field, particularly a kind of paddy planter is special Gearbox.

Background technology

Domestic paddy planter uses rice transplanter chassis mostly at present, does not need to spiral casing mechanism.New one In the paddy planter in generation, using tractor as power traction, advantage is can be general with most of agricultural tools, and shortcoming is Tractor can extrude very deep rut in paddy field, this just needs spiral casing mechanism to eliminate rut.Spiral casing mechanism moves Power comes from the PTO (power output device) of tractor, and the seeding of paddy planter, distance between rows and hills adjustment, rack imitate the actions such as type It is to be realized by hydraulic pressure, this just needs a hydraulic pump, and the power of pump equally comes from PTO.

Traditional paddy planter (i.e. the seed-sowing machine on rice transplanter chassis) is also that complete rice by PTO power output straight It broadcasts.But traditional paddy planter has the disadvantages that：

1：Rice transplanter chassis power output shaft is small, and horsepower is limited, is not suitable for making large-scale paddy planter；

2：Rice transplanter chassis does not have spiral casing mechanism, therefore does not need to the power splitting mechanism of one transverse direction of distribution；

3：The power of the sowing mechanism of rice transplanter chassis paddy planter comes from PTO, and PTO power is output to a speed change Case, then by gearbox mechanical transfer to sowing mechanism, this gearbox is uniaxial drive and output, can not be broadcast live Line-spacing spacing in the rows adjusts.

It then becomes necessary to the gear there are one the output of uniaxial drive twin shaft is distributed and is converted into action edge, to meet The requirements such as the rotating speed of hydraulic pump and spiral casing mechanism, torque, direction.

Utility model content

The purpose of this utility model is to provide a kind of paddy planter special gear box, realization one axis, two axis of input Output, makes paddy planter become a kind of general farm implements, carry out farm work can be all matched with any tractor.

The solution that the utility model solves its technical problem is：A kind of paddy planter special gear box, including case Body, is disposed with first axle, second axis parallel with first axle and the third axis vertical with first axle on the babinet, and described One end of one axis, the second axis and third axis is each passed through in babinet exposed after corresponding side wall, and box house is located in first axle One end on be disposed with the first driving cog and the first conical tooth, be located in second axis on one end of babinet and be disposed with the second biography Moving teeth, second driving cog and first are driven tooth engagement, are located in the third axis on one end of babinet and are disposed with the second cone Shape tooth, second conical tooth and the first taper tooth engagement.

As a further improvement of the above technical scheme, mounting cylinder, the installation are disposed in the one side wall of the babinet The both ends of cylinder are separately installed with a 3rd bearing, and the outboard end of mounting cylinder is equipped with third rotatory sealing and third end cap, institute State third axis one end sequentially pass through it is exposed after two 3rd bearings, third rotatory sealing and third end cap.

As a further improvement of the above technical scheme, there are one being respectively arranged on two opposite side walls in the babinet Clutch shaft bearing, the first axle are sleeved on two clutch shaft bearings, and the exposed junction of first axle passes through one of clutch shaft bearing, case Exposed after the first end cover in the first rotatory sealing and babinet on body, remaining next clutch shaft bearing is sealed by first end cover It gets lodged in babinet.

As a further improvement of the above technical scheme, there are one second bearing, institutes for arrangement by each clutch shaft bearing The second axle sleeve is stated in two second bearings, the second axis side exposed junction passes through one of second bearing, second on babinet Exposed after second end cover in rotatory sealing and babinet, remaining next second bearing is blocked by second end cover in babinet It is interior.

As a further improvement of the above technical scheme, the exposed junction of second axis and the exposed junction of first axle are staggered point Cloth two side walls opposite in babinet.

As a further improvement of the above technical scheme, first driving cog close to first axle exposed junction, described Exposed junction of one conical tooth far from the first shaft end.

As a further improvement of the above technical scheme, the gearratio of first conical tooth and the second conical tooth is 1:2, The gearratio of first driving cog and the second driving cog is 2:1.

The beneficial effects of the utility model are：The utility model in first axle by being disposed with the first driving cog and first After conical tooth, the second axis passes through the second conical tooth and the first taper by the second driving cog and the first transmission tooth engagement, third axis After tooth engagement, axis input, two axis output so that the utility model is suitable for seeder are realized.
