The extraordinary draught engine of chain type
Technical field
The present invention relates to a kind of extraordinary draught engine.
Background technology
Exceed in urban sewerage and drainage ability causes the ponding disaster urban waterlogging produced in city in precipitation or continuous precipitation, at river regulation, take to dig, expand, grade aggregate measures river regulation time, at transformation network of underground, expand caliber, when solving rain, dirty shunting, mix seriously owing to bearing water, current people can only use foul water pump to carry out draining.But the performance of anti-blockage of foul water pump, the height of efficiency, and cavitation performance, anti-erosion performance is mainly ensured by impeller and the large parts of pumping chamber two, due in bearing water mixing of being transferred containing being easily wound around or the fibre object of pack, therefore this kind of pump runner is easy to blocking, and pump is once blocked meeting makes pump cisco unity malfunction, even motor damage, thus cause blowdown not smooth.Therefore, need send someone when draining to keep an eye on, remove foreign material around foul water pump at any time, also need the obstruction taken by instrument in foul water pump if desired, and repeat possibility occurs and quite bothers.
Summary of the invention
For above-mentioned situation, the invention provides the extraordinary draught engine of a kind of chain type, it adopts formula of the rooting out water discharge method of bucket type, will mix seriously to bear water and progressively discharge, and removes " trouble and worry " thus.
The present invention is achieved in that the feature of the extraordinary draught engine of chain type is: the front and back ends of crawler-type mobile mechanism establishes ascending/decending leg, and ascending/decending leg divides into wheel; Crawler-type mobile mechanism is dispersed with accumulating bucket, accumulating bucket is connected with crawler belt through upper hinge, lower hinge;
Described accumulating bucket, it is front low, rear high oblique shape, and bottom is curved, and sharp mouth is established in the front end of bucket; Water leakage device can also be set up in accumulating bucket.
Crawler belt comprises chain, conduction band, establishes bogie wheel below crawler belt.
Electric lifting mechanism is established in ascending/decending leg, can in automatically controlled lower lifting.
Effect of the present invention is:
(1). the curved bottom of accumulating bucket, can the width of significantly constriction crawler-type mobile mechanism, be convenient to reduce complete machine height, add ascending/decending front and back ends leg, make machine operation height control at any time within optimum range.
(2). the accumulating bucket in crawler-type mobile mechanism can each specific admixture water of splendid attire or impurity.
(3). sharp mouth is established in one end of accumulating bucket, and this sharp mouth can be very stiff and demanding, roots out the hard foreign material of bottom.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.

In figure: 1. accumulating bucket, 2. crawler belt, 3. bogie wheel, 4. crawler-type mobile mechanism, 5. ascending/decending leg, 6. sharp mouth, 7. curved bottom, 8. wheel, 9. upper hinge, 10. play hinge.
Detailed description of the invention
As shown in the figure, the front and back ends of crawler-type mobile mechanism 4 establishes ascending/decending leg 5, and ascending/decending leg 5 divides into wheel 8; Electric lifting mechanism is established in ascending/decending leg 5, can in automatically controlled lower lifting.
Crawler-type mobile mechanism is dispersed with accumulating bucket 1, accumulating bucket 1 is front low, rear high oblique shape, bottom curved 7, and sharp mouth 6 is established in the front end of bucket; Can also water leakage device be set up in accumulating bucket 1, can each specific admixture water of splendid attire or impurity; Accumulating bucket 1 is connected with crawler belt 2 through upper hinge 9, lower hinge 10;
Crawler belt 2 comprises chain, conduction band, establishes bogie wheel 3 below load-bearing place of crawler belt 2.
When operation, driven by motor crawler-type mobile mechanism 4 rotates, and accumulating bucket 1 shovels into mixing water at low level, pours out mix water at height, after unlatching water leakage device, just can pour out impurity, is emitted on appointment place.Along with the advance of this machine, it can carry out excretion operation continuously to operation ground, does not give over to industry dead angle.
Structure of the present invention is not limited to form described in embodiment, and the further expansion that those of ordinary skill in the art makes according to the present invention all falls into protection scope of the present invention.
The drainage problem that chain type of the present invention extraordinary draining function efficient solution is determined in particular cases.
