Riding mower with noise reduction measure and hydraulic stepless speed change

Abstract

The invention discloses a riding mower with a noise reduction measure and hydraulic stepless speed change. The riding mower comprises a steerable front axle, a drivable rear axle with hydraulic stepless speed change, a frame with a double-protection lever, a mowing device with noise reduction, an engine with a noise elimination groove, a head housing with noise reduction, a noise elimination air filtering net, a saddle with noise reduction and a grass collection box with noise reduction, wherein the front axle is connected with two front wheels; the drivable rear axle is ocnencted with two rear wheels; the frame is arranged above the four wheels; the mowing device is arranged below the frame; the engine is arranged above the frame close to the front side; the saddle is arranged on the middle part above the frame close to the rear side; the grass collection box is arranged behind the mower; in addition, for personal protection of a riding operator, accessories such as earplugs, sound-proof cotton, ear muffs and a sound-proof helmet are arranged. The invention also introduces a heightening quadrilateral structure, diagrammatic design of a mowing part, a preferable thinking method and a comprehensive application method of the noise reduction measure to the entire mower.

Description

technical field [0001] The invention relates to a riding lawn mower used for mowing lawns in gardens, parks, roadsides, and sports venues. The main purpose of improvement is to make the comprehensive effect beneficial to wide-width mowing, noise reduction, environmental protection and safety. machine. Background technique [0002] Lawn mowers are widely used to mow grass in the manner chosen by people. Due to the poor maneuverability of the hand-push lawn mower, and when mowing in practice, due to the narrow cutting width at the front of the lawn mower, the phenomenon of repeated cutting and missing cutting often occurs, and it is necessary to re-cut and operate. Mowing grass on foot is very hard work. If you use a mount type, also called a riding lawn mower, you will feel different when sitting than standing, but the noise is louder. [0003] The muffler is widely used as a muffler for internal combustion engines, especially small gasoline engines, and is installed on th...

Problems solved by technology

The long strips of the two knives are perpendicular to each other and reversed so as not to interfere with each other; a double-sided V-shaped belt is used, and three tension pulleys are used. The main disadvantage is that because the knives have front and back, the cutting The front and rear of the disc are enlarged, resulting in the increase of the front and rear wheelbase, the length of the whole machine, the increase of the turning radius of the vehicle, the deterioration of the longitudinal potential stability coefficient, and the increase of cost, all of which are undesirable.

The two knives of another original mount-type lawn mower, although not one behind the other, see Figure 24 , because the two knives rotate in opposite directions so as not to interfere with each other, a double-sided synchronous belt is used, and two synchronous tension pulleys are used, which increases the cost
