Description

Scraper conveyor

Technical field

The utility model relates to a kind of conveying machinery, particularly a kind of efficient, energy-conservation scraper conveyor.

Background technology

At present, slat conveyer is widely used in every profession and trade.When carrying granule or granular material, mostly use double track " chain hook-type " slat conveyer or double track " chain-plate type " slat conveyer.They all are the tracks that its roll sleeve is held in installation below the upper and lower plates chain, drag roll sleeve by sprocket wheel and roll to advance to drive then and work the scraper plate of scraping the thing effect on the plate chain and scrape the hook operation, reach the purpose of conveying.

But there is following shortcoming in said structure:

1, low (under the service condition: the quality of material almost is half of plate chain to the power that effectively utilizes of the energy, promote material with the power pull plate chain of one times of material, effectively utilizes power less than 35%, even can be lower.)；

2, the use cost height (the in use continual back and forth friction of rolling of the bearing pin of plate chain, roll sleeve and track, cause that these parts wears are big, the life-span is short and service expenditure high);

3, accident more (the continual friction of roll sleeve and bearing pin can cause the reduction of their quality of fits to cause the plate chain growth, and the plate chain can be overthrown by driving chain wheel when returning and de-orbit, and will cause like this and hang bad and shutdown).

Summary of the invention

The purpose of this utility model is in order to overcome the prior art above shortcomings, provide a kind of efficient, energy-conservation, strengthen safety and reduce the scraper conveyor of use cost.

The utility model is achieved through the following technical solutions, and a kind of scraper conveyor comprises casing and is located at the end cap of its left and right sides end face; Two ends in casing are respectively arranged with driven sprocket and the drive sprocket that is installed on driven shaft bearing and the transmission shaft bearing; Two sprocket wheel upper ring caps have the plate chain, and scraper plate equidistantly is set on the plate chain in pairs, and the spacing between the scraper plate is identical with the pitch of sprocket wheel; It is characterized in that: between two sprocket wheels, install at least one can with plate chain ingear support roller.

The utility model is owing to the advantage that has adopted said structure to have is: efficient, energy-conservation, strengthen safety and reduce use cost.

Description of drawings

The embodiment of the indefiniteness that the utility model said structure can provide by accompanying drawing further specifies.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to enlarged view.

Among the figure: 1, casing; 2, plate chain; 3, lower railway; 4, inlet point; 5, tensioning screw; 6, driven shaft bearing; 7, transmission shaft bearing; 8, discharging opening; 9, roll sleeve; 10, support roller; 11, scraper plate; 12, end cap; 13 sprocket wheels; 14, slide plate.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Referring to accompanying drawing, the scraper conveyor among the figure comprises casing 1 and is located at the end cap 12 of its left and right sides end face; Two ends in casing are respectively arranged with driven sprocket and the drive sprocket that is installed on driven shaft bearing 6 and the transmission shaft bearing 7; Two sprocket wheel upper ring caps have plate chain 2, and scraper plate 11 equidistantly is set on the plate chain in pairs, and the spacing between the scraper plate is identical with the pitch of sprocket wheel; It is characterized in that: between two sprocket wheels, install at least one can with plate chain ingear support roller 10.Be provided with track 3 at bottom of shell, be set with roll sleeve 9 on the installation shaft between the every pair of scraper plate, when described roll sleeve is positioned at bottom of shell at the plate chain, just in time be positioned on the described track 3; What described driven shaft bearing 6 was installed in casing 1 left end can be on the slide plate 14 that casing moves, the both sides up and down of slide plate are arranged in and the fixing chute of casing, its left side is connected with tensioning screw 5 one ends by attaching parts, the other end of tensioning screw 5 passed with left end cap and was fixedly coupled part, was fixed by nut; Described scraper plate 11 has the shaving of increasing; Between two sprocket wheels, per 3～4 meters are provided with a support roller.

Above the casing that driven sprocket one end is installed, be provided with inlet point or/and inspection door 4 at the casing upper and lower of drive sprocket one end, is provided with inspection door and discharging opening 8 respectively.

Said structure is owing to the madial wall at casing 1 is equipped with and plate chain 2 ingear support rollers 10 every 3～4m.Therefore, support roller 10 holds up plate chain 2, make the friction force of plate chain 2 and support roller 10 much smaller than itself and the friction force that gets on the right track, this has just reduced friction force, has reduced reactive loss and wearing and tearing, (prove through prototype experiment: compare with original technology, the effective rate of utilization of the energy can improve more than 16% to have improved the effective rate of utilization of the energy.); In the neutral between the support roller 10, the sagging gravity of upper plate chain transmits the hoisting force that changes into the lower plate chain by sprocket wheel 13, thereby alleviated the pressure of lower plate chain on lower railway 3, further reduce friction force, reduced merit loss and wearing and tearing, (prove through prototype experiment: compare with original technology, the effective rate of utilization of the energy can improve more than 5% to have improved the effective rate of utilization of the energy.); The defective that neutral between the support roller 10 has remedied plate chain 2 and increases because of wearing and tearing, (prove through prototype experiment: the derailment accident of original technology accounts for 60% of total accident, compares with rising, and the utility model can improve safety more than 60% can to avoid derailment accident.), improved safety.

The another improvements of said structure have been to increase the height of scraper plate 11, and (prove through prototype experiment: compare with original technology, the effective rate of utilization of the energy can improve more than 16% also just to have increased the working area of scraper plate 11.), improved work efficiency.

Said structure and can reduce the maintenance of equipment expense of bringing because of loss because the effective rate of utilization of the energy can improve more than 37%, thereby has reduced use cost.

Principle of work of the present utility model: sprocket wheel 13 drags roll sleeve 9 and drives plate chain 2 then and move in a circle through support roller 10.

In sum, the utlity model has efficient, energy-conservation, strengthen security and reduce use cost Advantage.
