Problems solved by technology

[0007] In the process of opening and closing the bucket door of the above-mentioned drilling bucket, it is realized by the impact of the ground on the bucket door, and it is difficult to control the magnitude and direction of the impact force. Therefore, the reliability of the bucket door closing is low, and the operation process when the bucket door is closed It is relatively complicated and requires high technical requirements for the staff; at the same time, the efficiency of the above-mentioned bucket door closing method is low, which seriously affects the working efficiency of the drilling bucket

Abstract

The invention discloses a sluice gate device of a piling machinery. The sluice gate device comprises a sluice gate which is hinged to a bucket body through a first articulated shaft (22). The sluice gate device further comprises a power mechanism for driving the sluice gate to rotate around the first articulated shaft (22) so as to drive the sluice gate to close. Therefore, acting force for closing the sluice gate is provided by the power mechanism, and the acting force of the power mechanism can be predefined according to requirements during closing the sluice gate, thus the acting force formoving the sluice gate and the moving speed are stable, and the reliability of sluice gate closing is improved. Besides, the power mechanism is adopted to drive the sluice gate to close, which avoidsrepeating collisions, as a result, requirements on operation skills and experiences of operators are lowered, and the efficiency for closing the sluice gate is improved. The invention also discloses the piling machinery with the sluice gate device.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a bucket door device used for piling machinery. The present invention also relates to a piling machine comprising the above-mentioned bucket door device. Background technique [0002] With the rapid development of my country's economic construction, the market demand for various pile machinery is increasing. [0003] Many piling machines have a bucket door device. The following uses the rotary drilling rig as an example to introduce the function of the bucket door device in the piling machine and its working process. [0004] The construction process of modern construction projects generally starts with pile foundation construction. Therefore, pile hole construction is particularly important. With its advantages such as high drilling efficiency, rotary drilling rigs are increasingly widely used in pile hole operations under different geological conditions. . In the construct...
