In use, the mixing device 4 is a box formed by mixing a plurality of raw materials through the design of the pushing stirring device. After a plurality of raw materials are sequentially added, a layering phenomenon occurs in the mixing device 4, so that the mixed raw materials are difficult to be mutually fused and conveyed out from the discharge hole 402, and therefore, a pushing and stirring device is designed. When weighing device 3 emptys the raw materials, thereby drive gear roller 404 through starting third motor 403 and rotate not stopping, on the one hand with multiple raw materials misce bene, on the other hand last pivoted gear roller 404 also can with the raw materials acceleration in the mixing box 401 catch up to send to the position of discharge gate 402 and carry and go out, improved the quality and the speed of the batching machine ejection of compact.
The invention has the beneficial effects that:
(1) this self-compaction concrete proportioning machine through the setting of conveyer pipe, weighs in the final leading-in to a weighing device of the batching input port of stone raw material case, dry mortar raw material case and the three difference of water tank. The trouble that the bottom of various batching mouths all need to be provided with a weighing device is avoided in the arrangement, and the space, the installation and the use cost of the device are greatly saved.
(2) This self-compaction concrete proportioning machine, through grinding sieving mechanism's setting, stone raw material tank is arranged in assembling the stone raw materials in the self-compaction concrete raw materials. To self-compaction concrete, to the requirement of stone quality be higher than ordinary concrete far away, drop into stone raw material box with stone, only the stone within the regulation size can get into the conveyer pipe through the stone hole that the lapping plate upper surface was seted up inside, the outer stone of regulation size can accumulate the grinding of accepting the grinding rod at the upper surface of lapping plate. This setting makes great stone fall into the conveyer pipe from the stone pore department after according with the specification and carries out the blowing, and the quality of having controlled self-compaction concrete stone head raw materials has improved the quality of batching back product like this strictly.
(3) This self-compaction concrete proportioning machine sieves the design of device through the stirring, and the dry mortar of the inside transport of dry mortar raw material tank is formed by multiple powdered silt mixture, because placing of dry mortar, just pours into the dry mortar of dry mortar raw material tank inside and can produce the phenomenon of caking because the characteristic of inside multiple powder is different, consequently has set up the existence of stirring fan in the inside of dry mortar raw material tank. The part of caking of dry mortar is sprinkled through the rotation of stirring fan, makes the multiple powder in the dry mortar carry out abundant mixture simultaneously, gets into in the conveyer pipe after the screening through the filter sieve, has improved the quality of dry mortar raw materials greatly.
(4) According to the self-compacting concrete batching machine, through the arrangement of the falling locking cleaning device, when the device is positioned at an initial position, the deep column and the shallow column are both inserted into the shallow groove; due to the extrusion effect of the inner wall of the shallow groove, the deep column is tightly attached to the shallow column, and the whole upper edge plate is positioned above the material inlet hole; the raw material can be smoothly transferred through the material inlet hole. When the raw materials meet certain requirements, the upper edge plate can descend, and in the descending process, the shallow columns and the deep columns can fall into the deep groove from the inside of the shallow groove; due to the existence of the electromagnetic spring, the deep column can be popped and clamped into the deep groove, so that the locking of the whole upper edge plate is completed, and redundant raw materials input from the material inlet hole can be fed from the upper surface of the upper edge plate; the redundant raw materials can be discharged from the lower port of the redundant material outlet for next use, so that the cost of the raw materials is saved.
(5) This self-compaction concrete proportioning machine through weighing switching device's setting, under initial on-off state, through the inside reinforced processing that carries on of charging port hole pair weighing incasement portion, the raw materials is carried into weighing incasement portion back, is piled up at the upper surface of lower flange. As the time for feedstock delivery increases, the weight of the feedstock will increase. The raw material weight that the lower flange can the bearing is set up through the coefficient of stiffness that sets up adjustable spring, after reaching the specified weight, can make the lower flange sink to open the through-port that the weighing box leads to mixing arrangement. Carry into mixing arrangement with the smooth transport of certain weight's raw materials, satisfy and weigh and go on when carrying for the batching speed of device.
(6) This self-compaction concrete proportioning machine, through the design that promotes agitating unit, mixing arrangement is the case after multiple raw materials mix. After a plurality of raw materials are sequentially added, the layering phenomenon can occur in the mixing device, so that the raw materials which are well mixed are difficult to be mutually fused and conveyed out from the discharge hole, and the pushing and stirring device is designed. When weighing device emptys the raw materials, thereby drive the rotatory carrying on that gear rod does not stop through starting the third motor, on the one hand with multiple raw materials misce bene, on the other hand lasts pivoted gear rod and also can with the position of the raw materials acceleration in the mixing box transport to the discharge gate and go out, has improved the quality and the speed of the batching machine ejection of compact.
