Description

Technical Field

[0001] The utility model relates to the field of building engineering construction, in particular to a soil-digging mechanism with an air blowing function and a material-feeding and mixing integrated vehicle. Background Art

[0002] The moisture content of mud dried soil and other urban waste soil belongs to the high-humidity category. When entering the crushing and mixing device, it is easy to have bonding equipment and unsatisfactory crushing particle size, resulting in a decrease in the yield of qualified finished products. In the current treatment, quicklime must be added to the mud cake and the excavated soil from the foundation pit. After a certain period of static reaction, the moisture content of the high-humidity waste soil will gradually decrease and sandify. The sandified waste soil has the characteristics of looseness and low viscosity, which is convenient for crushing and mixing devices to handle. However, this method has the following defects: 1. The amount of dust during the process of ash mixing is extremely large, which is harmful to the health of the operators; 2. The amount of quicklime input is huge, resulting in a high cost of regeneration treatment; the static reaction time is long (generally seven days), and the lime attenuation can reach 30~43%; 3. It is not conducive to improving production efficiency, and requires sufficient product and semi-finished product stacking space.

[0003] To solve the above defects, Figure 1 As shown, the applicant's prior application proposed a feeding and mixing integrated vehicle (see CN202320669580.8 for details), which improves the treatment efficiency of waste mud and reduces the treatment cost. The integrated vehicle adopts a mechanical arm with a soil scraping mechanism, which is dedicated to crushing and feeding waste soil, and transports the waste soil to the feeding and mixing part at the rear end through a conveyor belt for crushing and mixing, thereby achieving efficient regeneration of waste soil.

[0004] However, the above-mentioned feeding and mixing vehicle still has the following defects in actual application: when the soil-scraping mechanism is crushing and scraping high-humidity soil, the soil will stick to the soil-scraping mechanism, resulting in poor crushing and scraping effects, affecting the regeneration quality of waste soil, and the frequency of manual regular cleaning of the soil-scraping mechanism is too high, resulting in increased costs and reduced production efficiency.

[0005] Based on this, this case is brought forward. Utility Model Content

[0006] The purpose of the utility model is to provide a soil scraping mechanism with a blowing function to solve the defects mentioned in the background technology.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A soil-digging mechanism with an air blowing function, comprising:

[0009] A turntable, a cutter head is mounted on the circumferential outer wall of the turntable, a cavity and a plurality of flow channels are opened inside, the cavity is arranged at the center of the turntable, one end of the flow channel is connected with the cavity, and the other end extends to the circumferential side wall of the turntable to form an air injection hole that penetrates the outside;

[0010] A rotating shaft is fixedly mounted on the central axis of the rotating disk, the end of the rotating shaft is open and hollow, and a flow hole communicating with the cavity is provided on the shaft wall;

[0011] The air pipe has one end connected to the air pump and the other end rotatably connected to the open end of the rotating shaft through a bearing. The high-pressure gas entering the air pipe enters the cavity through the flow hole on the rotating shaft and is then ejected from the jet hole through the flow channel.

[0012] Furthermore, the cutter head is blade-shaped or conical.

[0013] A material feeding and mixing integrated vehicle comprises a vehicle body and a mechanical arm arranged on the vehicle body, the end of the mechanical arm is provided with the above-mentioned soil scraping mechanism with blowing function, and the vehicle body is provided with an air pump connected with an air pipe.

[0014] The utility model has the advantages that, by arranging the jet structure on the soil-scraping mechanism, an air pump can be used during the soil-scraping work to quickly blow off the soil stuck on the soil-scraping mechanism, thereby ensuring the effect of crushing and scraping, ensuring the regeneration quality of the waste soil, and at the same time reducing the maintenance frequency of the soil-scraping mechanism, reducing production costs, and improving production efficiency.

[0023] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" herein are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] This embodiment proposes a material feeding and mixing vehicle, such as Figure 2 As shown, the present invention is the same as the prior art, and includes a vehicle body 1 and a mechanical arm 2. The vehicle body 1 is provided with a feeding and mixing mechanism, which can transport, crush and mix the input waste soil; the mechanical arm 2 is arranged at the front side of the vehicle body 1, and a soil digging mechanism 3 is provided at the end of the mechanical arm 2. Driven by the mechanical arm 2, the soil digging mechanism 3 can dig up the waste soil and feed it into the vehicle body 1.

[0025] like Figure 3 and Figure 4 As shown, the soil scraping mechanism 3 includes a rotating disk 301, a rotating shaft 302 and an air pipe 303. A blade-shaped cutter head 304 is installed on the circumferential outer wall of the rotating disk 301, and a cavity 3011 and a plurality of flow channels 3012 are opened inside. The cavity 3011 is arranged at the center of the rotating disk 301. One end of the flow channel 3012 is connected to the cavity 3011, and the other end extends to the circumferential side wall of the rotating disk 301 to form an air injection hole that penetrates the outside. Figure 3 As shown, the jet holes formed by a plurality of flow channels 3012 are uniformly distributed on the outer wall of the rotating disk 301 in the circumferential direction and are located between two adjacent cutter heads 304. When the jet holes blow out high-pressure gas, it is convenient to blow off the waste soil adhering to the cutter heads 304 and the rotating disk 301. The rotating shaft 302 is fixedly installed at the central axis of the rotating disk 301. One end of the rotating shaft 302 is open, and the rotating shaft 302 is a hollow tube, and a flow hole 3021 communicating with the cavity 3011 is provided on the shaft wall. One end of the air pipe 303 is used to connect with the air pump, and the other end is rotatably connected to the open end of the rotating shaft 302 through a bearing 305. The high-pressure gas entering the air pipe 303 enters the cavity 3011 through the flow hole 3021 on the rotating shaft 302, and then is ejected from the jet hole through the flow channel 3012.

[0026] The connection between the air pipe 303 and the bearing 305 can be a rigid pipe, and the rest can be a flexible pipe. The rigid part is convenient to connect with the bearing, and the flexible part is less affected by the movement of the robot arm 2, thereby ensuring the effect of jetting. When the shaft 302 rotates, the air pipe 303 is stationary due to the bearing 305, but the high-pressure gas output in the air pipe 303 can enter the shaft 302 through the bearing 305.

[0027] By setting up an air jet structure on the soil-digging mechanism 3, an air pump can be used during the soil-digging work to quickly blow off the soil stuck on the soil-digging mechanism 3, thereby ensuring the crushing and digging effect and the regeneration quality of the waste soil. At the same time, it can also reduce the maintenance frequency of the soil-digging mechanism 3, reduce production costs, and improve production efficiency.

[0028] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
