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?

風(fēng)鎬是用空壓機(jī)壓縮空氣為動(dòng)力的工具，壓縮空氣由管狀分配閥輪流分配于缸體兩端，使錘體進(jìn)行往復(fù)沖擊運(yùn)動(dòng)，使鎬釬打入工作物，致使分 裂成塊。

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.

手持的風(fēng)動(dòng)工具，用壓縮空氣推動(dòng)活塞往復(fù)運(yùn)動(dòng)，使鎬頭不斷撞擊。用于采礦、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.

風(fēng)鎬由配氣機(jī)構(gòu)、沖擊機(jī)構(gòu)和鎬釬等組成。沖擊機(jī)構(gòu)是一個(gè)厚壁氣缸，內(nèi)有一沖擊錘可沿氣缸內(nèi)壁作往復(fù)運(yùn)動(dòng)。鎬釬的尾部插入氣缸的前端，氣缸后端裝有配氣閥箱。

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.

在氣缸壁的四周有許多縱向氣孔，壓縮柱塞閥的彈簧而接通氣路，這些氣孔一端通配氣閥，推壓手柄套筒，另一端通入氣缸，各氣孔的長(zhǎng)度根據(jù)沖擊錘的運(yùn)動(dòng)要求配置，以便輪流進(jìn)氣或排氣，柱塞閥在螺旋彈簧作用下處于切斷氣路的常閉狀態(tài)。

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.

使沖擊錘在氣缸內(nèi)有規(guī)律地往復(fù)運(yùn)動(dòng)。沖擊錘向前運(yùn)動(dòng)時(shí)，錘頭打擊釬尾；沖擊錘向后運(yùn)動(dòng)時(shí)，氣缸內(nèi)的氣體封閉在配氣閥箱內(nèi)，形成柔性緩沖墊層，氣缸內(nèi)的氣體封閉在配氣閥箱內(nèi)，待重新配氣后再向前沖擊。錘頭打擊釬尾；沖擊錘向后運(yùn)動(dòng)時(shí)，風(fēng)鎬的啟動(dòng)裝置位于手柄套筒內(nèi)。在進(jìn)風(fēng)管和配氣閥之間有一柱塞閥控制氣路，柱塞閥在螺旋彈簧作用下處于切斷氣路的常閉狀態(tài)。

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.

風(fēng)鎬作業(yè)時(shí)，使鎬釬頂住施工面，另一端通入氣缸，推壓手柄套筒，壓縮柱塞閥的彈簧而接通氣路，在氣缸壁的四周有許多縱向氣孔，配氣閥隨即自動(dòng)配氣，氣缸后端裝有配氣閥箱。使沖擊錘不斷往復(fù)運(yùn)動(dòng)，打擊釬尾，破碎施工體。

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.
