浙江省天台农机修造厂经过几年的设计和改进,试制成功一种新型打井机(简称冲抓锥)。它是利用抓土机斗和其它机械相联结的一种机型。它的特点是在砂卵石地层中钻进,工效高于其它形式的打井机;钻进速度快,每抓一次需时60～180秒,一次能取砂土卵百50～150公斤,随钻孔的深浅而不同;造孔直径大,适用于多种提水工具,降低水井造价;结构简单,操作方便,操作技术容易掌握,一般农机厂可担负生产修配任务。经多年施工实践证明,能在各种土、砂石、砾石、卵石层中施工,效果显著,深受群众欢迎。打井机的多种用途冲抓式打井机,虽然是为开发地下水灌溉农田而设计的,能打30～40米深、直径1.1米的灌溉井或工业、民用井。但也能广泛地运用于其它土方工程,能做
Zhejiang Tiantai Agricultural Machinery Factory after several years of design and improvement, trial success of a new type of drilling machine (referred to as scratching cone). It is a type of machine that uses a grab bucket and other machinery. It is characterized by drilling in the sand and gravel stratum, the work efficiency is higher than other types of drilling machine; drilling speed, each time takes 60 to 180 seconds, a can take 50 to 150 kg of sand and eggs, while drilling Hole depth and different; hole diameter, suitable for a variety of lifting tools, reducing the cost of wells; simple structure, easy operation, easy to master operating techniques, general agricultural machinery factory can take the task of production and repair. After years of construction practice has proved that in a variety of soil, gravel, gravel, pebble layer construction, the effect is significant, welcomed by the masses. Multiple uses of drilling machine Scratching well drilling machine, although designed for the development of groundwater irrigation farmland, can hit 30 to 40 meters deep, diameter of 1.1 meters of irrigation wells or industrial, civilian wells. But it can also be widely used in other earthworks, can do
