Background

The grid dirt remover is a device for cleaning out the grid slag trapped by a grid from the water surface by using a mechanical method. The rotary grid dirt remover is a group of rotary grid chains assembled by rake teeth. Under the drive of the motor reducer, the rake teeth chain rotates in the reverse water flow direction, garbage is driven to be above the water surface in the rotation process of the rake teeth chain, and in the continuous movement process, the garbage loses support after moving to the highest point, and falls under the action of gravity.

However, in the actual decontamination process, some garbage can adhere to the rake teeth due to various garbage, and is difficult to fall off by gravity. Therefore, the existing grid dirt remover is generally provided with a sweeper independently, namely a group of brush wheels which rotate reversely to clean the rake teeth reversely. In this way, on one hand, an additional cleaner and power device are needed, the installation is troublesome, and the maintenance is difficult; on the other hand, as the cleaner is mostly soft brush hair, dirt with certain viscosity is difficult to clean effectively, and even the cleaner is polluted and blocked.

Detailed Description

One embodiment of the present invention will be described in detail below with reference to the attached drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

Embodiment one:

as shown in fig. 1 to 7, the grating cleaner provided by the embodiment of the invention comprises a cleaner body, wherein the cleaner body comprises a frame, a motor reducer, a chain and the like, and the cleaner body further comprises a mounting shaft 11 for mounting rake teeth, and the structure of the part is the same as that of the prior art and is not repeated. As shown in fig. 2 to 4, the rake teeth include a stopper 20 and a catching tooth 21, the stopper 20 is fixedly provided on the mounting shaft 11, one end of the catching tooth 21 is hinged to the mounting shaft 11, and the catching tooth 21 is positioned at a rear side of the stopper 20 in a moving direction of the mounting shaft 11 such that the catching tooth 21 can be turned over by a certain angle in a direction away from the stopper 20.

When the dirt remover works, the motor speed reducer drives the chain to rotate, the chain drives the installation shaft 11 to move when rotating, when moving to the under-water surface, as shown in fig. 2, the fishing teeth 21 generate a trend of overturning towards the stop block 20 under the action of gravity, but the fishing teeth 21 keep relatively static due to the blocking of the stop block 20, the fishing teeth 21 salvage garbage, then the rake teeth continue to move to the state shown in fig. 3 under the driving of the installation shaft 11, continue to move to the highest point to be changed to the state shown in fig. 4, when moving to the highest point, the fishing teeth 21 become inclined after crossing the highest point, at this time, the gravity center of the fishing teeth 21 deflects towards the direction away from the stop block 20, the fishing teeth 21 overturn towards the direction away from the stop block 20 under the action of gravity, and the garbage attached to the fishing teeth 21 slides due to the loss of support during overturning. The traditional rake teeth can not turn over, so that the resistance is large when the garbage slides down, and the catching teeth 21 can quickly turn down after the highest point, so that the garbage can quickly lose support, and the garbage can quickly fall down. When the fishing teeth 21 are turned to the maximum turning angle, the fishing teeth 21 are abutted against the mounting shaft 11, the fishing teeth 21 are suddenly stressed to generate vibration and stop to continue turning, and at the moment, garbage attached to the fishing teeth 21 can slide off from the fishing teeth 21 under the action of inertia, so that a better cleaning effect can be achieved without a sweeper.

Embodiment two:

on the basis of the first embodiment, as shown in fig. 5 to 7, the present embodiment further includes an elongated tooth 22, a storage chute is formed on the capturing tooth 21, a sliding block 221 is provided on the elongated tooth 22, the sliding block 221 is slidably disposed in the storage chute, the sliding block 221 can slide along a direction away from or approaching the mounting shaft 11, and the elongated tooth 22 and the stop block 20 are located at two sides of the capturing tooth 21.

Specifically, the storage chute has a T-shaped structure, the slider 221 is adapted to the shape of the storage chute, and as shown in fig. 7, the storage chute is internally provided with a blanking hole 211 therethrough, and the extension teeth 22 are shorter than the catching teeth 21. As shown in fig. 2 to 4, when the mounting shaft 11 rotates to the lower end, the lengthened teeth 22 slide down under the action of gravity to form a lengthened effect, so that more and larger garbage can be caught, and when the garbage with larger volume and harder texture is encountered, the lengthened teeth 22 shrink towards the mounting shaft 11 due to interference, thereby avoiding overlarge load. When the rake teeth continue to move to the position shown in fig. 3, the lengthened teeth 22 retract under the action of gravity (the whole rack is obliquely arranged), so that the garbage is driven to move towards the direction of the mounting shaft 11, and the garbage is prevented from falling off due to instability in the lifting process. When moving to the state shown in fig. 4, that is, when crossing the highest point, the lengthened teeth 22 and the catch teeth 21 turn over under the action of gravity, the lengthened teeth 22 slide in the direction away from the mounting shaft 11, and when the lengthened teeth 22 slide to the maximum displacement (the sliding block 221 slides to abut against one end of the receiving chute), the lengthened teeth 22 collide with the catch teeth 21, and further vibration is generated to enable the garbage attached to the catch teeth 21 and the lengthened teeth 22 to fall off.

Embodiment III:

on the basis of the first or second embodiment, since the garbage is salvaged from the water surface and has a large amount of water, the garbage is troublesome to transport and post-treat, and needs to be transported to a dehydration device for dehydration treatment, and in the transportation process, the garbage is easy to cause secondary pollution and increase the transportation difficulty due to more water, so the embodiment also comprises a dehydration device, which comprises a dehydration tank 30, a driving device and a pressure device;
