DETAILED DESCRIPTION

[0048] The embodiments of the application are described below by specific examples, and those skilled in the art can easily understand other advantages and effects of the application from the content disclosed in the specification. Obviously, the described examples are part of the examples of the application, not all. Based on the examples in the application, all other examples obtained by those skilled in the art without creative labor fall within the scope of the application.

[0049] Please refer to Figures 1-6This invention discloses an earthwork waste transportation device for water conservancy engineering construction, mainly used for pre-treatment during the earthwork waste transportation process. The main structure includes a casing 1, a hydraulic cutting device 3, a granulator 5, and a slugging assembly 7. The hydraulic cutting device 3 is installed inside the casing 1, and a rotating structure 4 is provided on the top of the hydraulic cutting device 3 for connecting an external high-pressure water pump to introduce water into the hydraulic cutting device 3. On the other hand, a waste hopper 6 is provided on one side of the casing 1, and a moving platform 2 is provided at the bottom. The moving platform 2 is a cast iron base equipped with casters. The waste hopper 6 is used to feed waste earthwork into the casing 1, where the hydraulic cutting device 3 crushes the earthwork into particles for easy transfer and processing.

[0050] In this embodiment, as Figure 1 The top of the hydraulic cutting device 3 is connected to the rotary joint 4, which is sealed to prevent liquid leakage and air ingress, thus ensuring fluid sealing. The rotary joint 4 can also change the size of the throttling gap, altering the fluid flow rate and pressure. Additionally, the bottom of the hydraulic cutting device 3 is connected to the granulator 5. A blistering assembly 7 is located on the other side of the casing 1, connected to the bottom of the granulator 5. The granulator 5 re-kneads and compresses the excavated soil debris into larger particles, which are then fed into the granulator 5, compressed into particles, and discharged into the blistering assembly 7, from where they are released to a designated location.

[0051] In some embodiments, such as Figure 5 The hydraulic cutting device 3 includes a feeding plate 31, a jet plate 33, and a drive shaft 35. A spline shaft 32 is inserted at the center of the feeding plate 31. The spline shaft 32 is used to drive the feeding plate 31 to rotate. The spline shaft 32 is hollow inside and is integrally connected with the jet plate 33. Since the upper end of the spline shaft 32 is connected to the rotary joint 4, high-pressure water can enter the jet plate 33 through the rotary joint 4 along the spline shaft 32.

[0052] Specifically, in this embodiment, such as Figure 6 The jet plate 33 has several jet holes 34 arranged tangentially along its outer edge. Each jet hole 34 is connected to the splined shaft 32. When water enters the rotary joint 4, it releases a high-pressure jet through the jet holes 34. The jet stream released from the jet holes 34 not only cuts the soil but also drives the jet plate 33 to rotate. In turn, the jet plate 33 drives the feed plate 31 to rotate, thus allowing the waste soil to be continuously cut by the jet plate 33. In addition, a drive shaft 35 is fixedly installed at the bottom of the jet plate 33. The drive shaft 35 is coaxially arranged with the jet plate 33 and the splined shaft 32, thereby driving the drive shaft 35 to rotate.

[0053] Based on the previous embodiment, it should be specifically explained that, as Figure 3The drive shaft 35 is connected to the granulator 5 to drive its normal operation. The granulator 5 includes a conveying structure 51 and a screw assembly. The conveying structure 51 is used to convey earthwork debris. The screw assembly is installed inside the conveying structure 51. One end of the screw assembly is coaxially connected to the conveying drive shaft 35, and the other end is coaxially connected to the granulation component 55. Thus, the earthwork debris is transferred along the conveying structure 51 by the drive shaft 35 driving the screw assembly. Specifically, the screw assembly includes a first screw 52, ​​a cross joint 53, and a second screw 54. The first screw 52 is hinged to the second screw 54 via the cross joint 53. The second screw 54 drives the granulation component 55 to rotate at the end of the conveying structure 51.

[0054] In this embodiment, as Figure 4 The conveying structure 51 includes a collector 511, a conveying pipe 512, and a clamp 513. The collector 511 is funnel-shaped, and its bottom is connected to the clamp 513 via the conveying pipe 512. The conveying pipe 512 is bent at approximately a right angle. To effectively convey the excavated soil, a screw assembly is arranged inside the conveying pipe 512. The granulating component 55 is sleeved on the other end of the conveying pipe 512 and abuts against the clamp 513. The end of the granulating component 55 is provided with a granulation hole 56. The granulating component 55 is a cylindrical structure with a granulation hole 56 at its end. The granulating component 55 is coaxially connected to the second screw 54. During the process of excavated soil debris being squeezed through the granulating component 55 by the screw assembly, the granulating component 55 rotates and is broken into large particles by the clamp 513. These particles are then conveyed to the dredged filling assembly 7 and blown out of the equipment by the dredged filling assembly 7.

[0055] In some embodiments, such as Figure 6 The feeding disc 31 includes a disc body 311, a central hole 312, and a spiral groove 313. The surface of the disc body 311 is coated with a wear-resistant layer. The central hole 312 is located at the center of the disc body 311. The central hole 312 is a spline hole and is fitted onto a spline shaft 32. The central hole 312 cooperates with the spline shaft, thereby driving the disc body 311 to rotate through the spline shaft 32. On the other hand, the spiral groove 313 is provided on the outer edge of the disc body 31, thereby conveying the soil located above the disc body 311 along the spiral groove 313 into the hydraulic cutting device 3. In this process, the soil can be ground by the spiral groove 313, and the soil is prevented from entering the machine housing 1 all at once, which would reduce the efficiency of the jet disc 33.

[0056] In some embodiments, such as Figure 3The dredging assembly 7 includes a dredging pipe 71 and a hollow rotating shaft 74. A granulation component 55 is inserted inside the hollow rotating shaft 74 and is located on the side of the dredging pipe 71 for feeding soil particles into the dredging pipe 71. An industrial fan 72 or a vacuum axial flow pump is installed at the tail end of the dredging pipe 71 for releasing a strong airflow to blow the soil particles into the air. A rotary motor is installed on the hollow rotating shaft 74. The rotary motor drives the dredging pipe 71 to move up and down through the hollow rotating shaft 74, thereby adjusting the dredging distance.

[0057] Furthermore, it should be noted that a cloth bag 73 can be installed at the top of the dredging pipe 71. When a truck is used to load waste soil particles, the soil particles can fall into the vehicle body through the cloth bag 73, which can effectively prevent the soil particles from splashing. In another case, if the selected waste dumping site is close to the construction site, the cloth bag 73 can be removed directly, and the soil particles can be directly dredged and filled into the dumping site over a large area.

[0058] In some embodiments, such as Figure 2 The waste hopper 6 includes a connecting pipe 61, a hopper 62, and a flange 63. The upper end of the connecting pipe 61 is connected to the hopper 62. The hopper 62 is semi-cylindrical and has a vibrating motor installed at its end to accelerate the entry of soil into the housing 1. The lower end of the hopper 62 is provided with a flange 63, which is connected to the housing 1 to improve the stability of the connection.

[0059] Based on the same inventive concept, this invention discloses a method of use, applying the earthwork waste transport equipment for water conservancy engineering construction as described above, and including the following steps:

[0060] Step 1: Put the waste soil into the waste funnel 6 so that the soil flows into the machine casing 1;

[0061] Step 2: Rotary joint 4 is connected to a high-pressure water pump through a pipe. The high-pressure water pump mixes water and grass seeds and inputs them into the hydraulic cutting device 3. The hydraulic cutting device 3 releases a jet to break up the soil and mix it to form mud blocks.

[0062] Step 3: The mud blocks enter the granulator 5 to form granules, which are then blown out to a designated location by the blow-filling assembly 7 or transported to a designated location by a loading truck.

[0063] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
