Description

Lawn mower frame and lawn mower

Technical Field

The utility model belongs to the lawn mower field, specifically speaking relate to a lawn mower frame and lawn mower.

Background

The small agricultural machine is smart and convenient, is suitable for various complex terrains, and is necessary to realize the multifunction of the small agricultural machine for saving cost, namely, the combination of various small agricultural machine bodies and various working parts is required to be realized, and the power of an engine positioned on the small agricultural machine body is transmitted to the working parts through a transmission mechanism.

The mower is a common small agricultural machine, and is particularly suitable for pasturing areas. The driving of the mower cutter head is generally realized by transmitting the power of the output end of an engine on the mower body to the cutter head through a transmission mechanism, the output end of the engine is generally higher away from the ground, but the cutter head of the mower cannot be too high away from the ground, and the height of the cutter head of the mower is preferably adjustable, so that the transmission mechanism is required to gradually approach the ground when transmitting the power, namely the transmission mechanism needs to realize the longitudinal transmission of the power.

On the other hand, a certain working space is needed for the mower cutter head, namely a certain transverse distance needs to be reserved between the mower body and the mower cutter head, namely a transmission mechanism needs to realize transverse transmission of power.

The transverse transmission of the power of the traditional mower is realized through belt transmission, a supporting mechanism and a transmission mechanism between a mower body and a mower working part occupy large space, and the loss of a belt is particularly serious due to the working property of the mower.
