Problems solved by technology

There is a snowplow driven by a horizontal-axis engine, the horizontal-axis engine drives the driving wheel, and the driving wheel drives the friction wheel structure to drive the snowplow. The friction wheel has a simple structure and low cost, but the friction wheel has a short service life of only dozens of hours. The rubber just wears out and must be replaced. Furthermore, since the driving torque of the snowplow is smaller than that of the lawn mower, if the above-mentioned horizontal shaft engine and friction wheel structure are applied to the lawn mower, the friction wheel structure will Shorter life, therefore, there is a need for a long life lawn mower driven by a horizontal shaft engine

Abstract

The invention relates to a mower. The mower comprises an engine, a first transmission assembly, a second transmission assembly and wheels, wherein the first transmission assembly comprises a crankshaft, an advancing compacting device, a driving wheel I and a belt I, and the second transmission assembly comprises a worm gear and a driven wheel device; the crankshaft is arranged on the engine, the stretching direction of the crankshaft is consistent with the traveling direction of the mower, and the crankshaft can be driven to do in-situ rotation by the engine; the advancing compacting device and the driving wheel I separately sleeve the crankshaft, and the driving wheel I can rotate along with the crankshaft; and the worm gear comprises a worm-wheel shaft which is arranged vertical to the crankshaft and a worm shaft which is arranged parallel to the crankshaft, the wheels sleeve the worm-wheel shaft, the driven wheel device sleeves the worm shaft, the belt I is wound on the driving wheel I and the driven wheel device in a loose manner, and the advancing compacting device can movably press the surface of the belt I so as to tighten the belt I. The mower is driven by the horizontal shaft engine so as to achieve the driven advancing of the entire mower, and thus the mower has a relatively high practical value.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a lawn mower. Background technique [0002] The existing lawn mowers on the market are generally driven by a vertical axis engine, and there is no lawn mower driven by a horizontal axis engine for the time being. There is a kind of snow plow that is driven by a horizontal axis engine, the horizontal axis engine drives the driving wheel, and the driving wheel drives the friction wheel structure to drive the snow plow. The friction wheel structure is simple and the cost is low, but the friction wheel structure has a short service life, only dozens of hours. If the rubber is worn out, it must be replaced. Further, since the driving torque of the snow plow is smaller than that of the lawn mower, if the above-mentioned horizontal axis engine and friction wheel structure are applied to the lawn mower, the friction wheel structure will The lifespan is shorter, therefore, it is necessary to pro...
