Problems solved by technology

When the crank is in operation, the force points are concentrated on one point, which can easily lead to bearing damage, resulting in insufficient rotational energy to fully utilize the torque and consume it. At the same time, the axial thrust of the connecting rod drives the piston to pull the cylinder, resulting in rapid wear and tear of the seal of the impact piston. Defects such as reduced performance, damaged impact force, etc.

Embodiment Construction

[0048] The present invention will be further described below in conjunction with accompanying drawing.

[0049] Such as figure 1 As shown, the gasoline engine breaker of the present invention includes a housing 1, a handle 2, a motor 3, a transmission mechanism 4 and an impact mechanism 5. The shape of the gasoline engine breaker is changed from "P" shape to "A" shape, and the engine is placed on the top of the breaker body, so that the overall center of gravity is centered, and the cracking of the aluminum side cover of the engine is eliminated after the connection and fixing points of the engine are reinforced. .

[0050] Such as figure 2 As shown, the gasoline engine breaker is radiated by the wind wheel rotating blast, and the casing 1 is provided with a wind wheel intake chamber 6, a cylinder heat dissipation chamber 7 and a muffler heat dissipation chamber 8, which effectively distinguishes the characteristics of cold air in and hot air out, and has a very The strong...

Abstract

The invention discloses a crushing pickaxe with a gasoline engine. The crushing pickaxe comprises a shell, a handle, the engine, a transmission mechanism and an impact mechanism. The engine is arranged on the top of a body of the crushing pickaxe with the gasoline engine, and the shell is provided with an air inlet chamber of a wind wheel, a heat dissipation chamber of a cylinder and a heat dissipation chamber of a muffler. The crushing pickaxe with the gasoline engine has the advantages that cold air inlet and hot air outlet characteristics are effectively distinguished from each other, an excellent heat dissipation effect can be realized, the service life of the integral engine can be prolonged, and stable running of the engine can be guaranteed.

Description

technical field [0001] The invention belongs to the field of excavation, shoveling and destroying solids, in particular to a gasoline engine breaking pick. Background technique [0002] The gasoline engine breaker is a safe, portable and practical digging and breaking tool. It can be used anytime and anywhere without relying on power supply, large air compressor, generator and other auxiliary equipment, and has been well received by users at home and abroad. By changing different machines and tools, it can be used in construction engineering, crushing engineering in road construction, electric power, telecommunications, fire rescue, cable trenching and pre-buried, maintenance, road maintenance, crushing and demolition in civil engineering, mining work, ice breaking shovel in severe cold areas Various excavations, shoveling and chiseling to destroy solid areas such as dredging of frozen and frozen roads. [0003] At present, the structure of gasoline engine breakers is desi...
