High-pressure abrasive feeding type wood cutting gun

Abstract

The invention discloses a high-pressure abrasive feeding type wood cutting gun. The high-pressure abrasive feeding type wood cutting gun structurally comprises a jet nozzle, an abrasive pretreating device, a high-pressure water pipe and a mixing cavity; the jet nozzle is connected to the bottom of the mixing cavity, the high-pressure water pipe is arranged in the mixing cavity, and the side face of the mixing cavity is connected with the abrasive pretreating device; and the abrasive pretreating device is composed of a link mechanism, a reset mechanism, a liquid level transmission mechanism, atiming transmission device, a linkage mechanism, a liquid level switch, a cleaning device and a partition plate, the partition plate is installed in the cleaning device, and the cleaning device is electrically connected with the linkage mechanism. According to the high-pressure abrasive feeding type wood cutting gun, abrasives can be cleaned, water feeding can be automatically stopped and stirringand timing can be started when water is fed to a certain water level, automatic water draining can be conducted after stirring is conducted for a period of time through the timing transmission device, the dust content of the abrasives can be greatly decreased, it is guaranteed that cutting is smoothly conducted, and the purchase cost is reduced.

Description

technical field [0001] The invention relates to a high-pressure abrasive wood cutting gun, which belongs to the field of high-pressure abrasive wood cutting guns. Background technique [0002] Water jet cutting processing technology is an environment-oriented cutting processing technology. During cutting processing, this method has low noise, no dust pollution, and no sparks. It is a relatively clean cutting processing method, and it is an ideal cutting technology for flammable and explosive places. method. Abrasive water jet cutting technology is a new cutting method developed in the early 1980s. This technology is a cutting processing technology gradually developed on the basis of water jet cutting technology. The emergence of this technology has greatly improved the cutting processing capability of water jet and further broadened the application range of water jet technology. [0003] When the existing cutting gun is in use, the water cutting sand with a large dust con...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a high-pressure abrasive wood cutting gun to solve the problem that the water-cutting sand with a large dust content is prone to moisture when the existing cutting gun is in use, causing dust in the abrasive, The phenomenon of soil consolidating into agglomerates leads to the plugging of the sand pipe, and the water cannot come out. On the contrary, there will be expansion or even water leakage in the sand pipe, which will invisibly increase the purchase cost
