在带式制砖机上,龙口的泥柔,常发生干裂和水裂的现象,这是一个长期没有解决的问题。龙口的润滑作用,一是用水,一是用干电池。采用水做润滑一般是将高于龙口4—7公尺的水,用鉄管或橡皮管引到龙口里去,并用风力控制水份的大小。由于水位高于龙口,压力大,当泥土经过龙口时,砖机中的空气,就被挤到龙口的鉄皮处,尤以龙口四角处较多。
On belt-type brick machines, the mud in Longkou is often chapped and cracked. This is a problem that has not been solved for a long time. Longkou lubrication, first, water, one with dry batteries. The use of water for lubrication is generally 4-7 meters above the Longkou water, with a stern pipe or rubber pipe lead to Longkou, and use the wind to control the size of the water. Since the water level is higher than Longkou, the pressure is great. When the soil passes through the Longkou, the air in the brick machine is squeezed into the furrow at Longkou, especially in the corners of Longkou.
