The air shovel mainly uses the compressed air provided by the air compressor as the power to make the hammer body in it move back and forth, and strike the shovel bit, so as to realize the chiseling operation of the shovel on metal and building materials. It is mainly used in casting, welding, construction and furnace maintenance. So, what are the characteristics of air shovel? What role does the press play?

风镐是用空压机压缩空气为动力的工具，压缩空气由管状分配阀轮流分配于缸体两端，使锤体进行往复冲击运动，使镐钎打入工作物，致使分 裂成块。

Pneumatic pick is a tool powered by compressed air of air compressor. Compressed air is distributed at both ends of cylinder body by tubular distribution valve in turn, which makes hammer body carry out reciprocating impact motion, and makes pick drill into work object, resulting in splitting into blocks.

手持的风动工具，用压缩空气推动活塞往复运动，使镐头不断撞击。用于采矿、筑路等。

The hand-held pneumatic tool uses compressed air to push the piston to move back and forth, so that the pick keeps hitting. Used for mining, road construction, etc.

风镐由配气机构、冲击机构和镐钎等组成。冲击机构是一个厚壁气缸，内有一冲击锤可沿气缸内壁作往复运动。镐钎的尾部插入气缸的前端，气缸后端装有配气阀箱。

The air pick is composed of a valve distribution mechanism, an impact mechanism and a pick drill. The impact mechanism is a thick wall cylinder, in which there is an impact hammer which can move back and forth along the inner wall of the cylinder. The tail of the pickaxe is inserted into the front end of the cylinder, and the rear end of the cylinder is equipped with a valve box.

在气缸壁的四周有许多纵向气孔，压缩柱塞阀的弹簧而接通气路，这些气孔一端通配气阀，推压手柄套筒，另一端通入气缸，各气孔的长度根据冲击锤的运动要求配置，以便轮流进气或排气，柱塞阀在螺旋弹簧作用下处于切断气路的常闭状态。

There are many longitudinal air holes around the cylinder wall, which compress the spring of the plunger valve and connect with the air passage. One end of these air holes is connected with the air distribution valve, push the handle sleeve, and the other end is connected with the cylinder. The length of each air hole is configured according to the movement requirements of the impact hammer, so as to take turns in or out air. The plunger valve is in the normally closed state of cutting off the air passage under the action of the spiral spring.

使冲击锤在气缸内有规律地往复运动。冲击锤向前运动时，锤头打击钎尾；冲击锤向后运动时，气缸内的气体封闭在配气阀箱内，形成柔性缓冲垫层，气缸内的气体封闭在配气阀箱内，待重新配气后再向前冲击。锤头打击钎尾；冲击锤向后运动时，风镐的启动装置位于手柄套筒内。在进风管和配气阀之间有一柱塞阀控制气路，柱塞阀在螺旋弹簧作用下处于切断气路的常闭状态。

Make the impact hammer move back and forth regularly in the cylinder. When the hammer moves forward, the hammer head strikes the drill tail; When the impact hammer moves backward, the gas in the cylinder is sealed in the valve box to form a flexible cushion. The gas in the cylinder is sealed in the valve box, and it will impact forward after the air is redistributed. Hammerhead striking drill tail; When the impact hammer moves backward, the starting device of the air pick is located in the handle sleeve. A plunger valve controls the air path between the air inlet pipe and the air distribution valve, and the plunger valve is in the normally closed state of cutting off the air path under the action of the spiral spring.

风镐作业时，使镐钎顶住施工面，另一端通入气缸，推压手柄套筒，压缩柱塞阀的弹簧而接通气路，在气缸壁的四周有许多纵向气孔，配气阀随即自动配气，气缸后端装有配气阀箱。使冲击锤不断往复运动，打击钎尾，破碎施工体。

When the air pick is working, make the pick against the working face, and connect the other end to the air cylinder. Push the handle sleeve, compress the spring of the plunger valve and connect the air passage. There are many longitudinal air holes around the cylinder wall, and the air distribution valve will automatically distribute air. The air distribution valve box is installed at the rear end of the cylinder. It makes the impact hammer continuously move back and forth to strike the drill tail and break the construction body.
