Description

Stubble machine power transmission

technical field

The technology relates to a stubble machine, specifically, a power transmission device for a stubble machine, especially a power transmission device suitable for a sand-grown shrub machine, and belongs to the field of agricultural machinery accessories.

Background technique

Most of the stubble machines use diesel engines as the main power, and the distance from the cutting device is far away. They need to be transmitted by multi-stage transmission. The structure is complex, the volume is large, and the power loss is large.

Contents of the invention

The purpose of this technology is to address the above-mentioned problems and provide a power transmission device for a stubble machine, the purpose of which is to improve its transmission efficiency and reduce unnecessary power loss.

This technology is realized through the following technical solutions:

The stubble machine power transmission device of the present technology includes a cylindrical gear box and two bevel gear boxes. Drive shaft, drive shaft extending to one side; drive shaft of one of the bevel gearboxes is connected to the output shaft of the power take-off; the cylindrical gearbox also has two cutterhead shafts, multiple driven shafts; each cutterhead shaft The cutter head shaft gear on the drive shaft meshes with the drive shaft gear on a drive shaft located in the cylindrical gearbox; the two drive shaft gears are meshed through the driven shaft gears on multiple driven shafts.

The above-mentioned stubble machine power transmission device is connected with a driving pulley on the top of the scraper shaft, and the driving pulley is arranged on the power input shaft of the conveying device through the driven pulley driven by a belt. The conveying device includes a conveying chain wound on the driving sprocket and the driven sprocket, and shift levers arranged on the conveying chain at intervals; the driving sprocket is arranged on the power input shaft, and the driven sprocket is arranged on the driven sprocket shaft.

The above-mentioned stubble machine power transmission device has two driven shafts.

In the above-mentioned stubble machine power transmission device, the transmission shaft of a bevel gear box is connected with the output shaft of the power output device through a universal coupling. The power output device and the bevel gearbox are connected by a universal coupling to ensure the stability of the transmission process.

The beneficial effect of the technology is that the power output device is directly connected with the gear box, which reduces the power loss and improves the working efficiency to a great extent. A power output device simultaneously drives the cutter head and the scraper cylinder to rotate, which simplifies the structure, is small in size, and has high transmission efficiency. The bevel gearbox connected to the scraper shaft can change the direction of rotation to meet actual needs.
