Description

Technical Field

[0001] The utility model relates to the technical field of garbage transportation, in particular to a construction garbage transportation device. Background Art

[0002] With the development of urbanization, more and more buildings are rising from the ground, and a lot of construction waste is generated. Directly landfilling these construction wastes will occupy a large amount of land resources. The toxic and hazardous substances produced by the construction waste landfill will also pollute the ecological environment around the landfill. At the same time, the recyclable aggregates, metals, glass, plastics, asphalt and other materials in the construction waste will also be wasted. In order to recycle construction waste, it needs to be transported to the construction waste recycling and treatment plant by garbage trucks for reuse. This treatment process requires the use of conveying devices.

[0003] In the process of conveying waste, existing construction waste conveying devices often first load the construction waste accumulated on the ground with a loader and pour it onto a conveyor belt, and then the conveyor belt throws the construction waste from a high place to a garbage truck waiting below the conveyor. During this process, a large amount of dust will be generated when the garbage is poured into and thrown from the conveyor belt. Existing conveying devices, such as the construction waste conveying device disclosed in patent authorization announcement No. CN 211686873U, have poor dust removal effects, resulting in serious pollution to the surrounding environment during the waste transportation process, which is not in line with environmental protection concepts. Utility Model Content

[0004] The purpose of the present utility model is to provide a construction waste conveying device to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A construction waste conveying device comprises a conveying frame, a conveyor belt, a lower dust cover and an upper dust cover, a conveyor belt is installed in the middle of the conveying frame, and an upper dust cover and a lower dust cover are respectively installed on the upper and lower ends of the conveying frame, an upper spray pipe and a lower spray pipe are respectively installed on the upper parts of the upper dust cover and the lower dust cover, the upper spray pipe and the water inlet and the water inlet of the lower spray pipe are connected to the connecting pipe installed on the side of the conveying frame, a plurality of nozzles are installed at the bottom of the upper spray pipe and the lower spray pipe, fixed plates are installed on both sides of the bottom of the conveying frame, a brush roller is rotatably installed between the two fixed plates, and one end of the brush roller is directly connected to the output shaft of the motor installed on the fixed plate.

[0007] As a further solution of the present invention: a feed hopper is installed on the lower dust shield, and dust shield plates are symmetrically arranged in the feed hopper. A torsion spring is installed at the bottom of one end of the dust shield, and the dust shield plate is elastically hinged to the inner wall of the feed hopper through the torsion spring.

[0008] As a further solution of the present invention: the brush roller is arranged just below the higher end of the conveyor belt.

[0011] As a further solution of the present invention: a guide plate inclined downward is installed at the highest end of the conveyor frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model cooperates with the lower dust cover, the upper dust cover, the lower spray pipe and the upper spray pipe to spray and block the dust raised at both ends of the construction waste conveying device, thereby greatly reducing the occurrence of dust during the construction waste conveying process and reducing the pollution to the surrounding air during the waste conveying process.

[0014] 2. The utility model is provided with a fixed plate, a motor and a brush roller. The motor can drive the brush roller to rotate under the conveyor belt, quickly sweeping away the construction waste adhering to the conveyor belt, avoiding the increase of the operating load of the conveying device due to a large amount of construction waste adhering to the conveyor belt, and achieving the effect of energy saving.

[0015] 3. The utility model sets a dust shield, which is connected to the feed hopper through a torsion spring. When garbage enters the feed hopper, the dust shield will be opened by heavy pressure, allowing the construction waste to pass through smoothly.

[0022] A feed hopper 8 is mounted on the lower dust shield 3, and a dust shield plate 9 is symmetrically arranged in the feed hopper 8. A torsion spring 10 is mounted at the bottom of one end of the dust shield plate 9, and the dust shield plate 9 is elastically hinged to the inner wall of the feed hopper 8 through the torsion spring 10;

[0023] Guide rollers 16 are installed on the baffles on both sides of the conveyor frame 1. The guide rollers 16 are rotatably connected to the conveyor frame 1. The guide rollers 16 can block and guide the construction waste at the edge of the conveyor belt 2, reducing the friction between the construction waste and the baffles on both sides of the conveyor frame 1, thereby better protecting the conveying device and reducing the running resistance;

[0024] A downwardly inclined guide plate 15 is installed at the highest end of the conveyor frame 1. The setting of the guide plate 15 can guide the construction waste output from the conveyor belt 2 so that the construction waste can fall smoothly into the compartment of the garbage transfer truck.

[0025] See also Figure 1 and Figure 3Fixed plates 12 are installed on both sides of the bottom of the conveyor frame 1, and a brush roller 14 is rotatably installed between the two fixed plates 12.

[0026] The working principle of this utility model is:

[0027] During use, when construction waste is poured into the feed hopper 8, the dust guard plate 9 is subjected to heavy pressure, which will cause the torsion spring 10 to be subjected to a torsional torque. The dust guard plate 9 will be pressed open under the action of the torsion spring 10, allowing the construction waste to fall onto the conveyor belt 2. After the construction waste passes through, the dust guard plate 9 will automatically reset under the restoring force of the torsion spring 10, preventing the dust in the feed hopper 8 from passing through the feed port. At the same time, spray water is transported from the lower spray pipe 5 to each nozzle 11 and sprayed out to contact the rising dust to reduce dust. When construction waste is thrown down from a high place of the conveyor belt 2, dust will be raised. At this time, the water sprayed from the nozzle 11 of the upper spray pipe 6 will come into contact with the raised dust to reduce dust and reduce dust. When the conveyor belt 2 throws the construction waste out and rotates, the motor 13 will drive the brush roller 14 to rotate to clean the construction waste adhered to the conveyor belt 2, so as to prevent the construction waste from rotating with the conveyor belt 2 and increasing the operating load of the conveying device.
