Conveying mechanism for tubular pile sand and gravel and control method thereof

Abstract

The invention relates to a conveying mechanism for tubular pile sand and gravel and a control method thereof. The conveying mechanism comprises a plurality of sections of sand and gravel conveying belt mechanisms. Output ends of the sand and gravel conveying belt mechanisms are connected to a sand and gravel conveying belt inclined downwardly. The lower part of the sand and gravel conveying belt is provided with two sections of the sand and gravel conveying belts A and B which respectively lead to different directions and present ''splayed'' shape. Mixing feed hoppers are respectively arranged under the A and B sections of conveying belt. The upper side and lower side of the mixing feed hoppers are respectively provided with a photoelectric sensor of accumulation amount of the sand and gravel for detecting the degree of the accumulation amount of the sand and gravel in the mixing feed hopper so as to achieve the control to the sand and gravel conveying mechanism. If the accumulation amount of the sand and gravel is overfilled, the operation of the sand and gravel conveying mechanism is stopped; and if the accumulation amount of the sand and gravel is too low, the sand and gravel conveying mechanism is started. The mechanism and the method change the prior conveying mode and control method, improve the production efficiency, realize intellectualized operation and have better market application prospective.

Description

technical field [0001] The invention relates to a conveying mechanism used in engineering, in particular to a conveying mechanism for sand and gravel materials and a control method thereof. Background technique [0002] Most of the existing pipe pile sand and gravel conveying mechanisms use two conveying mechanisms to convey sand and stone respectively, which is very expensive for long-distance sand and stone conveying, and takes up a lot of space, and most of them are manually controlled. The start and stop of the hopper, the material level of the hopper is observed by the eyes of the operator, and the operator must operate on site, so a large number of employees are required, and the human factor is large, the failure rate is high, and the accuracy of material level control is low. , the maintenance time is long after a failure occurs, which affects production, and various reasons have caused the existing sand and gravel material conveying mechanism and its control method ...

Problems solved by technology

[0002] Most of the existing pipe pile sand and gravel conveying mechanisms use two conveying mechanisms to convey sand and stone respectively, which is very expensive for long-distance sand and stone conveying, and takes up a lot of space, and most of them are manually controlled. The start and stop of the hopper, the material level of the hopper is observed by the eyes of the operator, and the operator must operate on site, so a large number of employees are required, and the human factor is large, the failure rate is high, and the accuracy of material level control is low. , the maintenance time is long after a failure occurs, which affects production. Various reasons have led to the existing sand and gravel material transmission mechanism and its control method not meeting the needs of production.
