Description

The anti-jamming smokeless discharge system of discharge adjustable amount

Technical field

The utility model belongs to technical field of concrete preparation, more particularly to a kind of transmission of transport concrete raw material is filled Put.

Background technology

Belt is often back to use in concrete mixing plant to transmit various concrete materials, such as sandstone aggregate, containing powder Fine aggregate or pure powder etc.；Two of usual conveyer belt is respectively wound around driving shaft and driven shaft surface, by rotating shaft, i.e., Power transmission shaft (master and slave moving axis) rotates and drives belt movement with the friction of belt contacts generation, so as to realize material sandstone Transmission.Due to no matter which kind of material, must all contain the tiny grains of sand or dust, therefore, transmission when be difficult to avoid that meeting In the non-transmission face side of conveyer belt, i.e., grains of sand dust can be stained with the medial surface of conveyer belt, now, grains of sand dust is with transmission Band is involved in driving shaft or driven shaft and conveyer belt joint, makes conveyer belt stuck；Because conveyer belt is typically one wider Belt, its length direction must keep perpendicular and its conveyer belt transmission plane is parallel with rotating shaft with each rotating shaft, otherwise when Belt because the grains of sand rub hinder, make belt occurs on power transmission shaft (rotating shaft) left and right offset when, belt can be stuck or even broken. On the other hand, Pipeline transport powder or the particulate feed material with powder are frequently encountered in concrete material transmission, for example The composites such as flyash, cement, various graded sand and stones etc., in such material of final output, in outlet often flue dust Diffuse, especially height of the final output end for splicing toter between it is typically much deeper than material and transmitted Connecting position height between transmission member in journey, it is easier to fly away flue dust, shroud whole place, not only environmental pollution Huge, damage health, is also a kind of greatly waste to the especially pure dust-like raw material of raw material.

Feed hopper is also that concrete mixing plant often uses auxiliary device, is generally connected with conveyer or agitator tank etc., use In graded sand and stone, powder or the concrete finished product of output concrete.As shown in figure 9, the feed hopper is in generally funnel-form, by upper Include splicing storehouse d1 and the discharging bin d2 being connected with splicing storehouse d1 lower ends successively under, splicing storehouse d2 is generally in cone, or It is the horn-like of rectangle in cross section, the cross section of the inwall of splicing storehouse d2 passages is generally rectangular, can use rectangular duct system Into or steel plate weld all around or bending closing form.Current feed hopper is mostly a fixed passage, and its channel sized is non-adjustable Section, or there is small part to adjust, but be by passageway break, by adjusting level directly using one piece of horizontal steel plate d03 Steel plate d03 maskings discharging bin d2 passage number carry out adjusting discharge capacity, cause side solid accumulation, and whole feed hopper stress Inequality, is easily damaged, and the side of discharging bin d2 passage is partial in the discharging of feed hopper, it is impossible to uniformly and is intensively discharged, is caused The pump truck or toter of splicing can not preferably determine to treat filling position.Due to material to be ensured in delivery section even Ground is conveyed, and can be just better protected from material and be dropped out conveyer belt, even if existing conveyer belt is provided with baffle plate, but because discharging regulation falls Side is partial to during doses, particularly with the conveyer belt of non-V-type, the material for being easily caused on a moving belt is not equal on a moving belt It is even to spread out, make whole transmission system unbalance stress, vibration becomes big, and solid accumulation when also resulting in transmission then overflows, and produces Flue dust, pollutes environment, wastes material.
