The following describes a shield tunneling machine belt conveying device according to an embodiment of the present invention with reference to fig. 1 to 4.

As shown in fig. 1 to 4, the belt conveying device of the shield tunneling machine according to the embodiment of the present invention includes a belt conveying mechanism 100 and a mud removing device 200.

The belt transfer mechanism 100 is provided with a belt 110, a driving mechanism 120 and a frame 130, the belt 110 and the driving mechanism 120 are mounted on the frame 130, and the driving mechanism 120 is used for driving the belt 110 to transfer soil. The driving mechanism 120 includes a motor 121 with a rotating shaft and a rotating roller 122, the motor 121 is fixed on the frame 130, the rotating shaft is connected with the rotating roller 122 to drive the rotating roller 122 to rotate, and the rotating roller 122 is attached to the belt 110 and can rotate relative to the frame 130, so as to drive the belt 110 to rotate. It is contemplated that the belt transfer mechanism 100 may be of other conventional configurations and, as the principles of construction of the belt transfer mechanism 100 are well known, they will not be described in detail herein.

The mud removing device 200 is provided with a mud removing plate 210 and a water spraying device 220, as shown in fig. 2, the belt 110 positioned at the upper part of the frame 130 is used for conveying mud, when the mud falls, the belt 110 rotates to the lower part of the frame 130, at this time, mud remains on the belt 110 due to the viscosity of the mud, the mud removing plate 210 is connected at the lower part of the frame 130 for scraping the mud rotated to the belt 110 at the lower part of the frame 130, and it is conceivable that the mud removing plate 210 can be welded on the frame 130 or connected in a buckling manner; meanwhile, as shown in fig. 3, the water spray device 220 is provided with a water spray pipe 221 extended to the inside of the fender 210, and the water spray pipe 221 is provided with a water spray port 222 toward the outside of the fender 210 for washing the belt 110, it is conceivable that the water spray pipe 221 is partially located outside the fender 210 and is connected with a water pump 223 for periodically spraying water. Through at the inside spray pipe 221 that sets up of mud removing plate 210, need not handheld spray pipe on the one hand to wash the belt, safe and reliable, on the other hand can effectively avoid the mud sewage that drops to get into the spray pipe and cause equipment to damage, and practiced thrift arrangement space, simple and practical greatly.

In some embodiments of the present invention, the water jet 222 is directed toward the belt 110 to achieve a better mud removal effect. As shown in fig. 2, the belt 110 moves obliquely upward and then turns to move obliquely downward, and the water jet 222 faces the direction opposite to the moving direction of the belt 110, so as to increase the cleaning effect and save water required for cleaning.

In some embodiments of the present invention, as shown in fig. 2, the upper portion of the mud removing plate 210 is inclined toward the side where the water spraying opening 222 is located, so as to shield the water spraying opening 222 in the vertical direction, thereby preventing the residual sewage and mud on the belt from falling into the water spraying opening 222 after the cleaning is finished, and causing the blockage and damage of the water spraying pipe 221.

In some embodiments of the present invention, as shown in fig. 1, the lower portion of the frame 130 is provided with a water baffle 230, and the water baffle 230 is located at the left and right sides of the mud guard 210. When washing, sewage inevitably sputters all around, and through set up breakwater 230 in the mud removal plate 210 left and right sides, can effectively prevent that sewage from sputtering the surrounding space and causing the pollution.

In some embodiments of the present invention, as shown in fig. 1, the two water baffles 230 are downward folded to save space and facilitate the collection of sewage.

In some embodiments of the present invention, as shown in fig. 1 and 2, the lower portions of the two water baffles 230 are provided with a connecting plate 240, and the connecting plate 240 is used for guiding the sewage to flow out. It is conceivable that a gap is left between the lower end of the desliming plate 210 and the upper end of the connection plate 240 for the outflow of sewage. After the water spray, sewage flows out along the water flow channel, and the water flow channel can be externally connected with a water storage tank to collect sewage. It is conceivable that the upper surface of the connection plate 240 has an inclination angle with respect to the horizontal plane to facilitate drainage of the sewage.

It is contemplated that the splash plate 230 and the attachment plate 240 may be integrally formed. In addition, the water guard plate 230 and the connection plate 240 may be formed of a transparent plastic material to facilitate observation of the washing condition.

In some embodiments of the present invention, as shown in fig. 2, when the upper surface of the connecting plate 240 is disposed obliquely upward toward the water spraying direction, a water baffle 230 may be disposed in front of the mud guard 210 at the forefront of the water spraying direction to prevent the sewage from splashing toward the direction.

In some embodiments of the present invention, the silt removing plate 210 is provided with an inwardly recessed drainage channel 211 above the water jet 222 to prevent the sewage from flowing into the water jet 222. As shown in fig. 3, the drainage channel 211 surrounds the upper side and the left and right sides of the water jet 222, and the water jet 222 protrudes relative to the drainage channel 211, so that the sewage above the water jet 222 flows along the drainage channel 211 toward the left and right sides of the water jet 222, and does not enter the water jet 222. It is conceivable that the drainage channel 211 may be provided in a pi-type or the like. As shown in fig. 3, the upper portion of the water jet 222 is projected in a triangular shape with respect to the drainage channel 211, and the tip of the triangular projection is directed upward, so that the sewage is guided to be dispersed and flowed down to both left and right sides of the water jet 222.

In some embodiments of the present invention, as shown in fig. 4, the water spraying pipe 221 can be set to protrude from the mud guard 210, i.e. further preventing sewage from flowing into the water spraying opening 222 along the mud guard 210, and simultaneously ensuring that the mud guard 210 shields the water spraying opening 222 in the vertical direction, so as to prevent sewage sludge from falling into the water spraying opening 222. In addition, as shown in FIG. 4, the water jet 222 can be arranged in a multi-angle orientation to wash a wider range of belts, thereby enhancing the washing effect.

In the description herein, references to the description of the term "example," "an embodiment," or "some embodiments," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example.
