Coaxial and automatic water feeder for water drill

Abstract

The invention discloses a coaxial and automatic water feeder for a water drill. The coaxial and automatic water feeder is characterized by consisting of eight parts, i.e., a water feeder shell (1), a reverse transitional threaded disc (2), a bisection type eccentric sleeve (3), a special water-drill main shaft (4), a driving bearing (5), a combined water guide shaft sleeve (6), a pumping pipe assembly (7) and a skeleton water seal (8), wherein the coaxial and automatic water feeder is arranged at the part of a rotary water sealing box of the traditional external water source drill; the reverse transitional threaded disc (2) is rotatably arranged on a screw thread (109) at the front end of a speed reducing box shell of the water drill; the bisection type eccentric sleeve (3) is of a structure which is sectioned into the form with a thick-wall semitile and a thin-wall semitile, is fastened on a shaft neck (9) of the installing section of the eccentric sleeve of the water-drill main shaft, is positioned by symmetric steel balls (15) and transfers the torque; and after being sheathed by the driving bearing (5), an eccentric sleeve shaft neck (64) is fixed by a clamping spring, and the water feeder shell (1) is arranged along the shaft, so that the coaxial and automatic water feeder which can be disassembled or assembled without pulling or disassembling the water-drill main shaft. The coaxial and automatic water feeder disclosed by the invention brings great convenience for specialized division and maintenance in production, is an upgraded product of an automatic water feeding technology for the water drill, and has good social and economic benefits.

Description

Technical field [0001] A coaxial automatic water feeder for rhinestones, which is a diaphragm pump that can be disassembled along the axis, is installed in the rotary water seal box of the traditional external water source rhinestones. The coaxial automatic water supply device for rhinestones utilizes the power of the rhinestone itself to realize self-absorption of water when the rhinestone is working, and supplies pressure water to the rhinestone through the built-in water channel. Because of its structural design that can be disassembled or assembled along the axis, it is very convenient for maintenance, which is conducive to the transition and upgrade of the traditional external water source water drill to the automatic water supply drill.

Problems solved by technology

[0002] ZL200420064236.3 patent, a random integrated automatic water supply system for engineering drilling machines, its basic concept has been proved to be a successful creation, but it has been slow to promote in recent years , It also proves that there are many design deficiencies. First of all, due to the structural design requirements of this random integrated automatic water supply system, the eccentric drive bearing that drives the diaphragm pump is installed on the rear shaft that is smaller than the shaft diameter of the rotating water seal section. On the neck, this requires this system to be pre-installed before the main shaft is assembled, which means that the main shaft must be removed during maintenance, which causes maintenance troubles. Furthermore, it uses a front stainless steel independent water seal box, which seems to be It is easy to pry out and replace the water seal box. In fact, for this kind of water seal box, the on-site workers cannot change the water seal without special tools, and they are forced to replace the water seal box parts as a whole, which increases the cost. This is the main reason why it is difficult to occupy the market and the promotion is slow. reason
