Description

Technical Field

[0001] This utility model relates to the field of slope construction technology, and more specifically, to an excavation device for high slope construction. Background Technology

[0002] High slopes refer to slopes with an excavation height of 20 meters or more. High slopes in road cuts are particularly prone to landslides, collapses, and other geological disasters and engineering accidents due to various unstable factors, attracting widespread attention from designers and construction personnel in civil engineering, geology, and highway construction. Generally, soil slopes with a height of 10 to 15 meters are considered high slopes. Slope excavation is carried out in layers from top to bottom. In hard rock areas, blasting techniques (loosening blasting) are used, while in soft soil areas, disturbance to the underlying soil mass is avoided.

[0003] Currently, during high slope excavation, excavators mainly use buckets to excavate soil layers. For relatively dry soil with small particles, the high slope excavation process generates a lot of dust, which cannot meet the environmental protection standards for excavation construction.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an excavation device for high slope construction, in order to achieve a more practical value. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide an excavation device for high slope construction that can solve the problem of environmentally unfriendly high slope excavation construction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an excavation device for high slope construction, comprising a body, a drive arm mounted on the body, a bucket mounted at one end of the drive arm, a positioning plate mounted on the lower surface of one end of the drive arm, an installation plate inserted into the positioning plate, a ventilation duct mounted on the installation plate, a dust suppression mechanism mounted inside the ventilation duct, and a fan mounted at one end of the ventilation duct.

[0007] In a preferred embodiment, a blocking block is fixedly connected to one end of the positioning plate, the mounting plate abuts against the blocking block, and the air duct is fixedly connected to the mounting plate.

[0008] In a preferred embodiment, the positioning plate and the mounting plate are connected by bolts.

[0009] In a preferred embodiment, the duct is arranged in a trumpet shape.

[0010] In a preferred embodiment, the dust suppression mechanism includes a spray frame installed inside the air duct. A high-pressure atomizing nozzle is fixedly connected to one side of the spray frame, and a water supply pipe is fixedly connected to the other side of the spray frame. One end of the water supply pipe passes through the air duct and extends outward.

[0011] In a preferred embodiment, a dust sensor is provided on the outer surface of the air duct, and a solenoid valve is provided on the water supply pipe, with a pipe joint provided at one end of the solenoid valve.

[0012] The technical effects and advantages of this utility model are as follows: 1. This excavating equipment for high slope construction utilizes a ventilation duct installed near the bucket on the drive arm. When the bucket is excavating on a high slope, a blower provides air pressure, and a dust suppression mechanism blows atomized water to cover the area around the bucket, reducing the likelihood of dust being generated during excavation. By placing the dust suppression outlet directly near the dust-generating point, the bucket, source control is achieved, resulting in dust removal efficiency far exceeding that of traditional methods involving fixed mist cannons around the construction site. This effectively suppresses dust diffusion and maximizes water mist utilization.

[0013] 2. The dust suppression unit is formed by integrating the ventilation duct, fan, and dust suppression mechanism. The installation plate and positioning plate are connected by plugging and then bolting, which facilitates the assembly and disassembly of the entire dust suppression unit. This excavation equipment, used for high slope construction, uses a dust sensor to monitor the PM10 concentration in the air around the ventilation duct in real time. By providing a dust suppression signal, it reduces the water consumption of the dust suppression mechanism's spray dust suppression.

[0014] 3. High slope construction often involves limited space, making it difficult to deploy large dust removal equipment. This invention integrates the dust removal function into the excavator required for the necessary construction, eliminating the need for additional space. Dust removal follows the equipment wherever it is moved.

[0015] 4. The detachable design allows ordinary excavators to quickly switch between ordinary digging mode and dust removal digging mode, making one machine multi-functional and improving equipment utilization. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See also Figures 1-5 This utility model provides an excavation device for high slope construction, which includes a body 1, a drive arm 2 on the body 1, and a bucket 3 at one end of the drive arm 2.

[0021] In this application, the body 1 is composed of the power unit, hydraulic system, slewing mechanism and traveling mechanism that play a core role in existing excavators. The drive arm 2 is composed of the boom hinged to the body 1 and the forearm hinged to the boom. The bucket 3 is hinged to one end of the forearm. By controlling the swing of the bucket 3, it is possible to excavate high slopes. The above structure and its details are all mature existing technologies.

[0022] In this embodiment: a positioning plate 4 is provided on the lower surface of one end of the drive arm 2, an installation plate 10 is inserted into the positioning plate 4, a duct 5 is provided on the installation plate 10, a block 41 is fixedly connected to the lower end of the positioning plate 4, the installation plate 10 abuts against the block 41, and the duct 5 is fixedly connected to the installation plate 10.

[0023] Positioning plate 4 is welded to drive arm 2, as shown in the image. Figure 3The structure is arranged in an inverted "T" shape. The mounting plate 10 is provided with a slot for insertion into the positioning plate 4. The mounting plate 10 can be inserted into the high end of the positioning plate 4 until the bottom end of the mounting plate 10 is limited by the blocking block 41. In this way, the mounting plate 10 can be fixed on the positioning plate 4. The purpose of this insertion method is to provide pre-support by inserting the mounting plate 10 into the positioning plate 4. The mounting plate 10 on the positioning plate 4 can be easily installed and removed by the sliding support. This makes it easier to lock with bolts as described below and facilitates installation and removal. After the mounting plate 10 is assembled, the ventilation duct 5 can be installed at the end of the forearm of the drive arm 2, which is close to the bucket 3. The ventilation duct 5 can provide a dust suppression channel for the dust generated by the excavation of the bucket 3.

[0024] In this embodiment, the positioning plate 4 and the mounting plate 10 are connected by bolts.

[0025] When the bucket 3 is used for other working conditions, such as underwater excavation, in order to avoid damage to the ventilation duct 5 and its structure, the bolts between the positioning plate 4 and the mounting plate 10 can be released, and the mounting plate 10 can be slid out on the positioning plate 4. In this way, the positioning plate 4 can remove the ventilation duct 5 and its structure on the drive arm 2, so that the ventilation duct 5 and its structure on the drive arm 2 can be easily disassembled and assembled.

[0026] In this embodiment, the air duct 5 is arranged in a trumpet shape.

[0027] The horn-shaped structure of the ventilation duct 5 means that the diameter of the ventilation duct 5 gradually increases from one end to the other, with the larger diameter end facing the bucket 3. This allows for a wider diffusion range when dust-suppressing water is sprayed inside the ventilation duct 5.

[0028] In this embodiment: a dust suppression mechanism is provided inside the air duct 5. The dust suppression mechanism includes a spray frame 6, which is installed inside the air duct 5. A high-pressure atomizing nozzle 7 is fixedly connected to one side of the spray frame 6, and a water supply pipe 8 is fixedly connected to the other side of the spray frame 6. One end of the water supply pipe 8 passes through the air duct 5 and extends outward. A fan 9 is provided at one end of the air duct 5.

[0029] The spray frame 6 is arranged in a ring structure. The spray frame 6 can be fixedly installed in the air duct 5 by fasteners. There are multiple high-pressure atomizing nozzles 7. The high-pressure atomizing nozzles 7 are connected to the spray frame 6. The atomization particle size of the high-pressure atomizing nozzles 7 is less than 50 micrometers. The water supply pipe 8 is connected to the spray frame 6.

[0030] During use, dust suppression water is supplied to the water pipe 8 through an external water supply system. The water enters the spray frame 6 and is atomized and sprayed out by the high-pressure atomizing nozzle 7. The atomization direction of the high-pressure atomizing nozzle 7 is set along the axis of the air duct 5. The fan 9 is started and blows air into the air duct 5 at the smallest diameter position. The blowing action causes the atomized water to be blown out from the largest diameter end of the air duct 5 until it spreads around the bucket 3. The diffusion radius is greater than one meter. In this way, the dust raised by the bucket 3 can achieve physical settling, which meets the concept of environmentally friendly excavation.

[0031] In this embodiment: a dust sensor 11 is provided on the outer surface of the air duct 5, and a solenoid valve 12 is provided on the water supply pipe 8, with a pipe joint provided at one end of the solenoid valve 12.

[0032] The dust sensor 11 is a PM10 sensor. The dust sensor 11 can be securely connected to the air duct 5 via a sensor mount. The pipe connector on the solenoid valve 12 can be connected to the existing water supply system using existing pipe connection technology. The water supply system is not shown in the figure. The existing water supply system may include a water tank, a water pump, and a water pump hose. The water tank can be set around the oil tank of the machine body 1. The water pump hose is connected to the end of the pipe connector. The water pump draws water from the water tank and inputs it into the water supply pipe 8 through the water pump hose. The dust sensor 11, the solenoid valve 12, and the water pump are all connected to the main controller and the power supply. The main controller can be a conventional known device such as a PLC controller that performs control, and the existing publicly available power connection technology will not be described in detail in the text.

[0033] The dust sensor 11 detects the dust generated by the bucket 3 digging at the maximum diameter of the ventilation duct 5. When the dust is detected, the main controller receives the dust suppression signal and controls the water pump to operate. The solenoid valve 12 opens, so that the dust suppression mechanism can physically suppress the dust generated by the bucket 3 digging. Similarly, when no dust is detected, the dust removal mechanism does not work. Therefore, the dust sensor 11 detects the concentration of PM10 in real time, which can minimize the water consumption of the dust removal mechanism.

[0034] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
