Technical Field

[0001] This utility model belongs to the field of construction dust control technology, and in particular relates to a dust suppression device for roadbed earthwork excavation. Background Technology

[0002] Dust suppression devices for roadbed earthwork excavation are equipment specifically designed to control and reduce the generation and spread of dust during the earthwork excavation of roads, railways and other engineering projects. They mainly reduce dust pollution generated during the excavation process by spraying water mist, which can protect the construction environment, the surrounding air quality and the health of people in the vicinity.

[0003] Existing dust suppression devices for roadbed earthwork excavation are usually placed on the ground to reduce dust generated during excavation. While this can reduce dust, the excavator will constantly move to change its excavation position, requiring staff to continuously reposition the dust suppression devices. This is time-consuming, labor-intensive, and inconvenient to use. Utility Model Content

[0004] To address the technical problem that existing dust suppression devices for roadbed earthwork excavation cannot be moved simultaneously with the excavator, requiring workers to constantly change the device's position, which is inconvenient, this utility model provides a dust suppression device for roadbed earthwork excavation.

[0005] This utility model is implemented as follows: a dust suppression device for roadbed earthwork excavation includes: a support plate and a support shell fixed to the excavator body, the support shell being provided with a water tank for storing water; a sleeve fitted on the support plate, the sleeve being hinged with a diversion pipe, the diversion pipe being provided with an atomizing nozzle for suppressing dust generated during roadbed earthwork excavation; a water pump fixedly installed on one side of the water tank, the water pump having a pumping pipe fixedly installed on its pumping end, one end of the pumping pipe extending into the interior of the water tank; a flexible hose fixedly installed on the water pump's draining end, one end of the flexible hose being fixedly connected to the diversion pipe, the flexible hose communicating with the interior of the diversion pipe; and a disassembly mechanism assembled on the sleeve for fixing the sleeve to the support plate.

[0006] Preferably, the disassembly mechanism includes: a housing fixedly mounted on the casing, a screw rotatably mounted on the housing, a handwheel fixedly mounted on the top end of the screw, a threaded sleeve threaded onto the screw, a locking block fixedly mounted on the bottom end of the threaded sleeve, the locking block being adapted to a locking groove on the support plate; and a limiting block fixedly mounted on the threaded sleeve, the limiting block being slidably connected to a limiting groove on the housing.

[0007] Preferably, the dust suppression device for roadbed earthwork excavation further includes an angle adjustment mechanism installed on the casing for adjusting the angle of the diversion pipe and the atomizing nozzle.

[0008] Preferably, the angle adjustment mechanism includes: a support block welded to the top of the housing, an electric push rod hinged to the support block, and the output rod of the electric push rod hinged to the top of the diverter pipe.

[0009] Preferably, a water supply pipe for adding water is fixedly installed on the water tank, and a cover for covering the water supply pipe is threaded onto the water supply pipe.

[0010] Preferably, the support shell is threaded with bolts, one end of the bolt is fixedly mounted with a knob, the other end of the bolt is fixedly mounted with a fixing plate, and the fixing plate is fixedly mounted with an anti-slip pad for clamping the water tank.

[0011] Preferably, the water supply pipe is equipped with a filter screen for filtering the water source. The filter screen is made of stainless steel and is used to block particulate matter in the water source.

[0012] Compared with related technologies, the dust suppression device for roadbed earthwork excavation provided by this utility model has the following beneficial effects:

[0013] This solution utilizes a water pump to deliver water from the tank to a distribution pipe during the excavation of the roadbed earthwork by the excavator. Under water pressure, the water is then sprayed from atomizing nozzles on the distribution pipe to suppress dust generated during the excavation. Since the atomizing nozzles move with the excavator when it changes excavation positions, this solution significantly reduces the workload of workers compared to existing dust suppression devices for roadbed earthwork excavation. It is also more convenient to use. Because the water tank can be removed from the support shell, and the shell can be removed from the support plate using the disassembly mechanism, the device can be easily removed from the excavator. This allows workers to move the device to confined spaces using a trolley or place it in a fixed location for dust suppression. Attached Figure Description

Detailed Implementation

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a dust suppression device for roadbed earthwork excavation, such as Figure 1-5As shown, the dust suppression device for roadbed earthwork excavation includes: a support plate 2 and a support shell 3 fixed to the excavator body 1, wherein a water tank 11 for storing water is provided on the support shell 3; a sleeve 4 sleeved on the support plate 2, wherein a diversion pipe 5 is hinged to the sleeve 4, and an atomizing nozzle 6 is provided on the diversion pipe 5, the atomizing nozzle 6 being used to suppress dust generated during roadbed earthwork excavation; a water pump 9 fixedly installed on one side of the water tank 11, wherein a water pump pipe is fixedly installed on the water pump 9's pumping end, one end of the water pump pipe extending into the interior of the water tank 11; a flexible hose 10 fixedly installed on the water pump 9's draining end, one end of the flexible hose 10 being fixedly connected to the diversion pipe 5, and the flexible hose 10 communicating with the interior of the diversion pipe 5; and a disassembly mechanism assembled on the sleeve 4 for fixing the sleeve 4 to the support plate 2.

[0023] In this solution, during the excavation of the roadbed earthwork by the excavator body 1, a large amount of dust will be generated. In order to suppress this dust, the water pump 9 needs to be started simultaneously. The water pump 9 will transport water from the water tank 11 to the diversion pipe 5 through the water pipe and hose 10. Finally, under the action of water pressure, the water will be sprayed out from the atomizing nozzle 6 on the diversion pipe 5 to suppress the dust generated by the excavator body 1 during the roadbed earthwork excavation. When the excavator body 1 needs to change the excavation position, the atomizing nozzle 6 will move with the excavator body 1. Compared with the existing dust suppression device for roadbed earthwork excavation, this solution can greatly reduce the labor intensity of the workers and is more convenient to use. Since the water tank 11 can be removed from the support shell 3, the shell 4 can be removed from the support plate 2 by operating the disassembly mechanism. This allows the workers to easily remove the device from the excavator body 1 so that people can use a trolley to move the device to some narrow places for use or place it in a fixed position for dust suppression.

[0024] In a further preferred embodiment of this utility model, the disassembly mechanism includes: a housing 12 fixedly installed on the housing 4, a screw 13 rotatably installed on the housing 12, a handwheel fixedly installed at the top end of the screw 13, a threaded sleeve 14 threadedly installed on the screw 13, a locking block 15 fixedly installed at the bottom end of the threaded sleeve 14, the locking block 15 being adapted to the locking groove on the support plate 2; and a limiting block 16 fixedly installed on the threaded sleeve 14, the limiting block 16 being slidably connected to the limiting groove on the housing 12.

[0025] In this embodiment, the disassembly mechanism not only fixes the housing 4 to the support plate 2, but also facilitates the removal of the housing 4 from the support plate 2. During disassembly, the screw 13 is rotated by handwheel, which drives the screw sleeve 14 to move vertically. At the same time, the limiting block 16 connected to the screw sleeve 14 slides on the limiting groove. The screw sleeve 14 drives the locking block 15 to disengage from the locking groove on the support plate 2. After disengagement, the housing 4 can be pulled to one side to disengage it from the support plate 2. By reversing the operation, the housing 4 can be fixed to the support plate 2, making disassembly and assembly relatively convenient.

[0026] In a further preferred embodiment of the present invention, the dust suppression device for roadbed earthwork excavation also includes an angle adjustment mechanism installed on the housing 4 for adjusting the angle of the diversion pipe 5 and the atomizing nozzle 6.

[0027] In this embodiment, by using an angle adjustment mechanism, the atomizing nozzle 6 can spray water to suppress dust at different heights.

[0028] In a further preferred embodiment of the present invention, the angle adjustment mechanism includes: a support block 7 welded to the top of the housing 4, an electric push rod 8 hinged to the support block 7, and the output rod of the electric push rod 8 being hinged to the top of the diversion pipe 5.

[0029] In this embodiment, when the angle adjustment mechanism is in use, the electric push rod 8 is activated, which drives the diverter tube 5 to rotate on the housing 4, thereby realizing the angle adjustment of the atomizing nozzle 6. This enables the atomizing nozzle 6 to spray water and reduce dust at different heights, making the adjustment relatively convenient.

[0030] In a further preferred embodiment of the present invention, a water supply pipe 17 for adding water is fixedly installed on the water tank 11, and a cover 18 for covering the water supply pipe 17 is threaded onto the water supply pipe 17.

[0031] In this embodiment, the use of the water inlet pipe 17 allows personnel to easily add the required water to the water tank 11. The use of the cover 18 can cover the water inlet pipe 17 after the water is added to prevent external impurities from entering the water inlet pipe 17.

[0032] In a further preferred embodiment of this utility model, a bolt 20 is threadedly installed on the support shell 3, a knob is fixedly installed on one end of the bolt 20, and a fixing plate 21 is fixedly installed on the other end of the bolt 20. An anti-slip pad for clamping the water tank 11 is fixedly installed on the fixing plate 21.

[0033] In this embodiment, the water tank 11 can be fixed inside the support shell 3 by the combined use of bolt 20, knob, fixing plate 21 and anti-slip pad. At the same time, it is also convenient for personnel to remove the water tank 11 from the support shell 3. When removing, the bolt 20 is turned by the knob. The bolt 20 will drive the fixing plate 21 to move, so that the anti-slip pad on the fixing plate 21 moves away from the water tank 11. At this time, the water tank 11 can be removed from the support shell 3. By the reverse operation, the water tank 11 can be fixed inside the support shell 3.

[0034] In a further preferred embodiment of the present invention, a filter screen 19 for filtering water is provided on the water supply pipe 17. The filter screen 19 is made of stainless steel and is used to block particulate matter in the water.

[0035] In this embodiment, the use of filter screen 19 can filter the water added to water tank 11 to prevent particulate matter from affecting the operation of water pump 9 and causing damage to water pump 9.

[0036] In summary, compared with related technologies, this solution, through the use of water pump 9, can transport water from water tank 11 to diversion pipe 5 during the excavation of roadbed earthwork by excavator body 1. Finally, under the action of water pressure, the water will be sprayed out from atomizing nozzle 6 on diversion pipe 5 to suppress the dust generated by excavator body 1 during roadbed earthwork excavation. Since the atomizing nozzle 6 will also move with excavator body 1 when excavation position is changed, it can greatly reduce the labor intensity of workers compared with existing roadbed earthwork excavation dust suppression devices. It is also more convenient to use. Since water tank 11 can be removed from support shell 3 and shell 4 can be removed from support plate 2 by operating disassembly mechanism, it is convenient for workers to remove the device from excavator body 1. This allows people to move the device to some narrow places for use by using a cart, or place it in a fixed position for dust suppression.
