Description

A kind of trash rake

Technical field

The present invention relates to a kind ofly to tackling water channel before intake, the pumping plant, and can fish for the sewage disposal apparatus of foreign material.

Background technology

Fast development along with the water conservancy project industry, before intake, pumping plant, need at first carry out the interception of large scale foreign material in the water channel and in the water channel of sewage disposal system, otherwise the large scale foreign material enter and may cause device damage, treatment effect to reduce in the road processing links of back.Usually, people just have grid to realize interception to the large scale foreign material, but after work a period of time, along with the gathering of foreign material, can block grid, block current.Therefore, some grid production unit has proposed the multiple technologies scheme for addressing this problem, and shrouds device technical schemes such as (guards) as adopting the grab bucket device from what grasp the foreign material assembled under water, coat rotation outside grid.The former the situation that grab bucket breaks grid often occurs in real work; The latter very easily blocks when the guard perforation density is too small, and eyelet is excessive, and foreign material can enter eyelet, from guard internal congestion grid, cause the removing difficulty bigger, and guard when rotated, owing to attached on the grid, make that the transmission resistance is very big, cause energy consumption very big.As can be seen, the former belongs to open tupe above-mentioned two kinds of technical schemes, but its treatment effeciency is low, and work hidden danger is big; The latter belongs to closed tupe, but its maintenance difficulties is big, and power consumption is big.Both behind obstruction, all need to shut down removal of impurities when work; The water flow that passes through can change because of the amount of obturator.

Summary of the invention

The present invention is directed to above problem, provide a kind of water channel can not get clogged, can guarantee the trash rake of stability of flow.

Technical scheme of the present invention is: comprise frame, be located at the drive motors and the chain drive mechanism of frame top, the drive sprocket of chain drive mechanism is located at frame top and frame bottom respectively, the drive chain of chain drive mechanism is a pair of, is located at the frame both sides respectively, and it also comprises some tooth harrows and axostylus axostyle; Some axostylus axostyles are parallel to each other between the equidistant drive chain of being located at the frame both sides, form to drive chain link; The two ends of each axostylus axostyle link to each other with drive chain respectively; Described tooth harrow has sickle shaped briar tooth and handle, and described handle is provided with two hole one and the holes two that are used to connect adjacent axostylus axostyle; Tooth harrow is hinged on the adjacent axostylus axostyle by hole one and hole two, the interlaced setting of the tooth harrow on the adjacent axostylus axostyle.

Also comprise the tooth harrow flusher, described tooth harrow flusher is arranged between the frame top drive sprocket, the turnover direction that flushes out mouth down deflection driving chain link of tooth harrow flusher.

It also is provided with slag bucket, and described slag bucket is located at the below of the flushing outlet of described tooth harrow flusher.

Tooth harrow continuous motion among the present invention when meeting foreign material, can be caught on foreign material, and is promoted to a top of the trellis, when upset (sprocket wheel trailing edge place, top), foreign material " are toppled over " in slag bucket, and the operation nature, compact conformation, simple; " topple over " effect for improving in upset decontamination place, the present invention also is provided with pulsed high pressure gas water backwashing device, and the foreign material that make hook on the tooth harrow carry out for next circulation scrubbing smoothly in time fully towards falling in the slag charge bucket, get ready.Tooth harrow of the present invention is provided with each other at interval, is crisscross arranged between the toothrow rake up and down, therefore can leave enough water spaces of crossing, thereby guarantee passing through of current.The present invention does not have the foreign material stop and blocked aquaporin when work, so the stability of flow of current, high efficiency.

The specific embodiment

The present invention as Figure 1-3, comprise frame, be located at the drive motors 1 and the chain drive mechanism of frame top, the drive sprocket 4 of chain drive mechanism is located at frame top and frame bottom respectively, the drive chain 2 of chain drive mechanism is a pair of, be located at the frame both sides respectively, it also comprises some tooth harrows 3 and axostylus axostyle 8; Some axostylus axostyles 8 are parallel to each other between the equidistant drive chain 2 of being located at the frame both sides, form to drive chain link; The two ends of each axostylus axostyle 8 link to each other with drive chain 2 respectively; Described tooth harrow 3 has sickle shaped briar tooth and handle, and described handle is provided with two hole one and the holes two that are used to connect adjacent axostylus axostyle 8; Tooth harrow 3 is hinged on the adjacent axostylus axostyle 8 by hole one and hole two, the tooth harrow 3 interlaced settings on the adjacent axostylus axostyle 8.

The flusher 5 that also comprises tooth harrow 3, described tooth harrow flusher 5 is arranged between the frame top drive sprocket 4, the turnover direction that flushes out mouth down deflection driving chain link of tooth harrow flusher 5.

It also is provided with slag bucket 6, and described slag bucket 6 is located at the below of the flushing outlet of described tooth harrow flusher 5.Drop down onto in the slag bucket 6, as shown in Figure 4 so that the foreign material 9 of hook on the tooth harrow 3 are dashed.

When making tooth harrow, the structure of tooth harrow is made up of falculate hook part, crank; The tooth that colludes of tooth harrow is sickle shaped, helps catching on foreign material; Increment is the obtuse angle, becomes arcuation, helps harrowing when upset the foreign material that catch on are toppled over down, and promptly foreign material come off under the effect of gravity naturally, and rake teeth the phenomenon of stumbling can not occur colluding to foreign material.Rabble arm is provided with two holes.This hole is used for installing axostylus axostyle.Preferably establish two holes, have two to do the force to rake like this, effect has: (1) tooth harrow can be done and parallel plane motion when plane motion, and motion is steady, the mixed and disorderly dancing in the time of can not appearing at an application point.(2) controlled: phase mutual friction, interference in the time of an application point can not occurring during several tooth harrow motions.(3) initiatively, effectively upset.When tooth harrow is made cycle operation, also promptly harrow when rotating to reverse side by the front on sewage disposal apparatus top, put forth effort (a bit be the center of circle, another point is made circular motion) meeting active, effectively upset owing to be at 2, the foreign material on the tooth harrow are toppled over, fall into slag bucket.Rabble arm surface, hook face do not have corner angle, are arcuation, avoid foreign material to occur colluding when toppling over and stumble on rabble arm or hook face.
