Description

Technical Field

[0001] The utility model relates to the technical field of concrete spraying machine components, in particular to a cooling device for a rotor feeding system of a concrete spraying machine. Background Art

[0002] One of the core components of a rotor-type concrete sprayer is the rotor feed assembly, which includes the rotor body, rubber plates, and rotating lining. During construction, since the upper and lower rubber plates are stationary while the rotor body rotates continuously, a dynamic seal must be achieved between the rubber plates and the rotating lining. This requires a clamping mechanism to apply a certain amount of pressure between the rubber plates and the rotating lining.

[0003] After the spraying machine has been used for a long time, a large amount of heat is generated by the relative movement and friction between the rubber plate and the rotating liner under pressure, which will cause the temperature of the rubber plate and the rotating liner to rise sharply, accelerate the aging and wear of the rubber plate, and greatly reduce the service life of the rubber plate and the rotating liner. Frequent replacement of the rubber plate and the rotating liner not only increases the construction cost, but also affects the construction progress. In order to solve the above problems, we proposed this concrete spraying machine rotor feeding system cooling device. Utility Model Content

[0004] The main purpose of the utility model is to provide a cooling device for a rotor feeding system of a concrete spraying machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cooling device for a rotor feeding system of a concrete spraying machine comprises a hopper seat, an upper sealing plate, an upper steel liner, a rotor body, a lower steel liner, a lower sealing plate and a panel. A plurality of upper sealing rings are provided on the upper end of the upper sealing plate. A cooling mechanism for reducing the temperature of the upper steel liner is provided on the hopper seat. The cooling mechanism comprises an upper water inlet pipe connected to the hopper seat, an upper water inlet ball valve is provided on the upper water inlet pipe, a lower water inlet pipe is connected to the panel, a lower water inlet ball valve is provided on the lower water inlet pipe, a plurality of lower sealing rings are provided on the panel, and a filtering mechanism for filtering a water source is provided in the upper water inlet pipe.

[0007] Preferably, the filtering mechanism includes a first filter screen arranged in the upper water inlet pipe, and a first pull rod is fixedly connected to the side wall of the first filter screen.

[0008] Preferably, a first mounting cylinder is fixedly connected to the inner wall of the upper water inlet pipe, a first mounting ring is threadedly connected to the inner wall of the first mounting cylinder, and the first mounting ring is fixedly connected to the first filter screen.

[0009] Preferably, a second filter screen is provided in the lower water inlet pipe, and a second pull rod is fixedly connected to the side wall of the second filter screen.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This device is equipped with a cooling mechanism. By adding an upper water inlet pipe, an upper water inlet ball valve, a lower water inlet pipe and a lower water inlet ball valve to the hopper seat and the panel, cooling water enters the inner and outer continuous flat parts between the upper and lower rubber plates and the rotating liner through the double cooling water holes on the rubber plate for circulating cooling. This can effectively reduce the temperature of the rotating liner, greatly increase the service life of the rubber plate and the rotating liner, and reduce the frequency of replacing the rubber plate and the rotating liner, which not only reduces the construction cost, but also improves work efficiency and speeds up the construction progress.

[0014] 2. This device is equipped with a filtering mechanism that can filter the water entering the hopper seat from the upper water inlet pipe through the first filter screen to prevent sand and gravel impurities from entering the inner and outer ring continuous planes between the upper and lower rubber plates and the rotating liner, causing component wear, thereby extending the service life of the equipment;

[0015] 3. This device is equipped with a second filter screen, which can filter the water entering the hopper seat from the upper water inlet pipe, preventing sand and gravel impurities from entering the inner and outer ring continuous planes between the upper and lower rubber plates and the rotating liner, causing component wear, thereby increasing the service life of the equipment.

[0024] A filtering mechanism for filtering water is provided in the upper water inlet pipe 12 . The filtering mechanism includes a first filter screen 16 provided in the upper water inlet pipe 12 . A first pull rod 17 is fixedly connected to a side wall of the first filter screen 16 .

[0025] In the present invention, a first mounting tube 14 is fixedly connected to the inner wall of the upper water inlet pipe 12, a first mounting ring 15 is threadedly connected to the inner wall of the first mounting tube 14, and the first mounting ring 15 is fixedly connected to the first filter screen 16, so that the position of the first filter screen 16 can be fixed in the upper water inlet pipe 12.

[0026] In the present invention, a second filter screen 20 is provided in the lower water inlet pipe 13 , and a second pull rod 21 is fixedly connected to the side wall of the second filter screen 20 , which can filter the water entering the lower sealing plate 8 and reduce the possibility of clogging the lower sealing plate 8 .
