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

Pile tube sandstone material connecting gear and control method thereof

Technical field

The present invention relates to the connecting gear used on a kind of engineering, particularly sandstone material connecting gear and control method thereof.

Background technology

Existing pile tube sandstone material connecting gear all is to adopt two connecting gears to transmit sand, building stones respectively mostly, and it is just very high that this transmits cost for remote sand, building stones, and it is big to take up room; And all be manually to control the startup of belt conveyor and stop mostly, the material level of hopper all is to rely on operative employee's eyes to observe, the operator must operate at the scene; Therefore need a large amount of employees, and artificial factor is bigger, fault rate is higher; Material level precise control rate is low; The back maintenance time that breaks down is long, and influence is produced, and various reasons has all caused existing sandstone material connecting gear and control method thereof not to meet the needs of production.

Summary of the invention

The object of the invention is to relate to a kind of pile tube sandstone material connecting gear and control method thereof, and it can change existing transfer mode and control method thereof, enhances productivity, and realizes intellectualized operation.

Technical program of the present invention lies in relating to a kind of pile tube sandstone material connecting gear; Comprise plurality of sections sandstone material conveyer mechanism; It is characterized in that: said plurality of sections sandstone material conveyer mechanism mouth is connected with downward-sloping sandstone material belt conveyor; Said sandstone material belt conveyor below is provided with two sections and is sandstone material belt conveyor A, the B that " eight " font is led to different directions respectively; Wherein A section belt conveyor is positioned on the bearing of trend of downward-sloping sandstone material belt conveyor; Said A section belt conveyor upper end is hinged with the turning lap plate that overlaps mutually with said downward-sloping belt conveyor bottom or B section belt conveyor upper end, and designs a kind of control method of this pile tube sandstone material connecting gear, and it is characterized in that: said sand, the building stones accumulating amount opto-electronic pickup that is mixed into the hopper upper and lower sides is used to survey the degree that is mixed into sand, building stones accumulating amount in the hopper; If sand, building stones accumulating amount overfill; Then stop the operation of sand, building stones connecting gear,, then start sand, building stones connecting gear if sand, building stones accumulating amount are low excessively.

The invention has the advantages that: realize intellectualized operation, efficient improves greatly, and productive costs reduces greatly, has the stronger market competitiveness, and easy to operate, and safety also is greatly improved.

The specific embodiment

The present invention provides a kind of pile tube sandstone material connecting gear; Specific embodiments comprises plurality of sections sandstone material conveyer mechanism 1; It is characterized in that: said plurality of sections sandstone material conveyer mechanism mouth is connected with downward-sloping sand, building stones belt conveyor 2; Said sand, stone transport conveyer belt below are provided with two sections and are sandstone material belt conveyor A, the B that " eight " font is led to different directions respectively; Wherein A section belt conveyor is positioned on the bearing of trend of said downward-sloping transport conveyer belt, and A section belt conveyor upper end is hinged with the turning lap plate 3 that overlaps mutually with downward-sloping belt conveyor bottom or B section belt conveyor upper end.

A, B section belt conveyor below are respectively arranged with and are mixed into

hopper

4,5, and the said hopper upper and lower sides that is mixed into is respectively equipped with sand, building stones accumulating amount opto-

electronic pickup

6,7.

Turning lap plate is by cylinder 8 controls that are arranged on the frame, and cylinder is hinged through the movable end and the turning lap plate of piston rod 9.

And design a kind of control method of this pile tube sandstone material connecting gear; It is characterized in that: said sand, the building stones accumulating amount opto-electronic pickup that is mixed into the hopper upper and lower sides is used to survey the degree that is mixed into sand, building stones accumulating amount in the hopper; If sand, building stones accumulating amount overfill; Then stop the operation of sand, building stones connecting gear,, then start sand, building stones connecting gear if sand, building stones accumulating amount are low excessively.

Be respectively arranged with Rolling

motor

10,11,12,13,14 on said plurality of sections sand, the building stones belt conveyor, for construction safety, the Rolling motor operation is in proper order: during start; Near the Rolling motor that is mixed into hopper operation earlier, from the close-by examples to those far off, start successively; This helps preventing to start shooting simultaneously and causes undertension, and is during shutdown, earlier out of service away from the Rolling motor that is mixed into hopper; Draw near, shut down successively, this helps preventing that sand, building stones from producing accumulation on belt conveyor.

Its principle of work is following:

When needs when being mixed into hopper 4 chargings, drive cylinder, make turning lap plate overlap mutually with downward-sloping belt conveyor, as shown in Figure 2.

When needs when being mixed into hopper 5 chargings, drive cylinder, make turning lap plate overlap mutually with B section belt conveyor, as shown in Figure 3.

Be located at and be mixed into hopper upper and lower sides accumulating amount opto-electronic pickup and be mainly used in and survey the accumulation degree be mixed into sand, building stones in the hopper, stop charging when accumulating amount is too high, cross when low, start the conveyer mechanism charging.

When operation start, the operation of Rolling motor is in proper order: near the Rolling motor that is mixed into hopper operation earlier, from the close-by examples to those far off, and start successively, promptly 10 → 12 → 13 → 14, perhaps be 11 → 12 → 13 → 14.

When out of service, the operation of Rolling motor for earlier out of service away from the Rolling motor that is mixed into hopper, draws near in proper order, shut down successively, and promptly 14 → 13 → 12 → 10, perhaps be 14 → 13 → 12 → 11.
