Drill bucket capable of opening bucket door continuously to discharge soil forcibly

Abstract

The invention relates to a drill bucket capable of opening a bucket door continuously to discharge soil forcibly, which comprises a drill bucket body, a drill bucket bottom door, a door opener and a soil discharging device, wherein the drill bucket bottom door is positioned at the lower end opening of the drill bucket body; a lock catch is arranged at one end of the drill bucket bottom door and is matched with a bucket door hook of the door opener; the other end of the drill bucket bottom door is hinged with the drill bucket body by a bucket door hinge; the door opener comprises a push-down mechanism arranged on a component capable of moving up and down relative to the drill bucket and a door opening mechanism arranged on the drill bucket body; and after acting on the door opening mechanism to open the drill bucket bottom door in the process of moving down, the push-down mechanism breaks away from the door opening mechanism to continue to move down. The drill bucket has the advantagesof eliminating impact force to equipment in the soil discharge process of a drilling machine, reducing energy consumption and improving the reliability of the equipment, along with good soil discharge effect.

Description

technical field [0001] The invention belongs to the technical field of construction machinery and relates to a drilling rig, in particular to a drilling bucket which continuously opens the bucket door and forcibly unloads soil. Background technique [0002] On multifunctional rotary drilling rigs, drilling buckets are often used for drilling. There is a door at the bottom of the ordinary drilling bucket, and there are cutting teeth on the door for cutting soil. The middle of the drilling bucket is a hollow drill barrel to accommodate the soil cut by the cutting teeth. There is a square head on the drill bucket for connecting with the drill pipe, and a mechanism for opening the bucket door. The mechanism includes a push rod, bucket door hook, hinge, etc. for opening the bucket door. When working, the drilling rig lowers the hollow drill bucket into the hole on the ground through the drill pipe; the power head drives the drill bucket to rotate and advance in the hole through t...

AI Technical Summary

Problems solved by technology

Although the drill bucket can solve the problem that the clay is not easy to fall off in the drill bucket and the soil cannot be unloaded during the rotary excavation operation in the cohesive soil layer to a certain extent, but after the bottom door of the drill bucket is opened by the door opening mechanism, due to the unloading of the soil plate It is connected with the bottom door. The opening of the bottom door is limited to a small angle, which is not conducive to unloading soil. Open further, still do not overcome the drawback of existing drilling bucket soil unloading method, on the other hand, in the drilling bucket cutting earth process, soil can enter in the upper drilling bucket of soil unloading plate through the gap and circular hole of unloading soil plate, Will affect the use of the drill bucket
