Description
Technical Field
[0001] This utility model relates to the field of pipe jacking machine technology, and in particular to a pipe jacking machine with smooth mud discharge and graded crushing. Background Technology
[0002] In the fields of municipal engineering, underground utility tunnel construction, and integrated pipeline laying, trenchless construction technology has become one of the core technologies for underground space development due to its minimal impact on ground traffic, surrounding buildings, and the ecological environment. Pipe jacking machines are key equipment for trenchless construction.
[0003] However, in the existing technology, the crushing mechanism of the existing pipe jacking machine is mostly a single-stage crushing design. During the crushing process, the crushing force is insufficient, which causes large pieces of slag to directly enter the subsequent sludge discharge system, becoming a hidden danger of pipe blockage. In addition, soft soil is easy to stick to the cutter head or crushing teeth, forming mud cakes, which not only reduces the crushing efficiency, but also causes uneven particle size of slag, further aggravating the sludge discharge resistance. Utility Model Content
[0004] The purpose of this invention is to address the problem that existing pipe jacking machines mostly use a single-stage crushing design, which results in insufficient crushing force during the crushing process, causing large pieces of slag to directly enter the subsequent sludge discharge system, becoming a potential hazard for pipe blockage. Furthermore, soft soil easily adheres to the cutter head or crushing teeth, forming mud cakes, which not only reduces crushing efficiency but also leads to uneven slag particle size, further exacerbating sludge discharge resistance. Therefore, this invention proposes a graded crushing pipe jacking machine with smooth sludge discharge.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pipe jacking machine for smooth sludge discharge and graded crushing, comprising a pipe jacking machine frame, a pipe jacking propulsion mechanism mounted on the top surface of the pipe jacking machine frame, a motor drive mechanism mounted on the output end of the pipe jacking propulsion mechanism, the motor drive mechanism being driven by the pipe jacking propulsion mechanism to move linearly, a transmission rod mounted on the output shaft end of the motor drive mechanism, a cutter disc mounted on the end of the transmission rod, a discharge box provided on the back of the cutter disc, the discharge box being movably sleeved on the outer wall of the transmission rod, a water inlet pipe and a drain pipe fixedly connected to the back of the discharge box, a mud and water treatment tank mounted on one side of the pipe jacking machine frame, a feed pipe mounted on the top surface of the mud and water treatment tank, the feed pipe and the drain pipe being connected through a mud and water pump pipeline, a crushing box mounted on the inner wall of the mud and water treatment tank, a reduction motor mounted on the end of the crushing box, a conical crushing screw rotatably connected to the inner wall of the crushing box, and the conical crushing screw being fixedly connected to the output shaft end of the reduction motor.
[0006] Preferably, a discharge pipe is connected through the bottom surface of the mud and water treatment tank, the interior of the discharge pipe is connected to the interior of the crushing tank, and the bottom end of the feed pipe penetrates the inner wall of the mud and water treatment tank and is connected to the interior of the crushing tank.
[0007] Preferably, an electrical control box is installed on the outer wall of the pipe jacking machine frame, and a deflection seat is installed on the bottom surface of the pipe jacking machine frame.
[0008] Preferably, the deflection seat includes a connecting plate, a rotating frame, a base, a hydraulic cylinder one, and a hydraulic cylinder two. The connecting plate is installed on the top surface of the base, and the rotating frame is rotatably connected to the top surface of the connecting plate.
[0009] Preferably, one end of the hydraulic cylinder is rotatably connected to the end of the connecting plate, and the end of the telescopic rod of the hydraulic cylinder is rotatably connected to the outer wall of the rotating frame.
[0010] Preferably, one end of the pipe jacking machine frame is rotatably connected to the top surface of the rotating frame, and the second hydraulic cylinder is installed between the pipe jacking machine frame and the side wall of the rotating frame.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, high-pressure water can be injected into the discharge box in real time through the water inlet pipe, which mixes with the slag to form a mud-water mixture; the discharge pipe is connected to the feed pipe through the mud-water pump pipeline, which stably transports the pretreated mud-water mixture to the mud-water treatment tank; the geared motor outputs low-speed, high-torque power to drive the conical crushing screw to rotate; the conical crushing screw adopts a conical variable diameter design to adapt to the slag after primary crushing. Through spiral extrusion and shearing action, the slag is further crushed to achieve the goal of graded crushing, solving the problem that the traditional fixed tooth assembly cannot dynamically adapt to the particle size of the slag, while ensuring that the crushed slag is uniform, providing a guarantee for smooth subsequent mud discharge.
[0012] 2. In this utility model, the discharge pipe penetrates the bottom surface of the mud and water treatment box and is connected to the crushing box, so that the fine particle mud and water mixture after secondary crushing can be directly discharged, avoiding the accumulation of slag in the crushing box. Its design in conjunction with the conical crushing screw improves the mud discharge efficiency. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0017] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a pipe jacking machine for smooth sludge discharge and graded crushing, including a pipe jacking machine frame 1. A pipe jacking mechanism 2 is installed on the top surface of the pipe jacking machine frame 1. A motor drive mechanism 21 is installed at the output end of the pipe jacking mechanism 2. The pipe jacking mechanism 2 drives the motor drive mechanism 21 to move linearly. A transmission rod 22 is installed at the output shaft end of the motor drive mechanism 21. A cutter head 23 is installed at the end of the transmission rod 22. A discharge box 24 is provided on the back of the cutter head 23. The discharge box 24 is movably sleeved on the transmission... The outer wall of the rod 22 and the back of the discharge box 24 are fixedly connected to the water inlet pipe 25 and the discharge pipe 26. A mud and water treatment box 5 is installed on one side of the pipe jacking machine frame 1. A feed pipe 51 is installed on the top surface of the mud and water treatment box 5. The feed pipe 51 and the discharge pipe 26 are connected through a mud and water pump pipeline. A crushing box 53 is installed on the inner wall of the mud and water treatment box 5. A reduction motor 55 is installed at the end of the crushing box 53. A conical crushing screw 54 is rotatably connected to the inner wall of the crushing box 53. The conical crushing screw 54 is fixedly connected to the output shaft end of the reduction motor 55.
[0018] The specific settings and functions of this embodiment are described below. The motor drive mechanism 21 provides rotational power to the transmission rod 22. The transmission rod 22 connects the motor drive mechanism 21 to the cutter head 23. The cutter head 23 employs a multi-set wear-resistant crushing tooth design. The rotation of the cutter head 23 crushes and disperses the material, controlling the initial particle size of the slag from the source. The discharge box 24 is movably fitted onto the outer wall of the transmission rod 22, neither affecting the rotation of the transmission rod 22 nor hindering the efficient collection of slag from the cutter head 23, thus preventing slag from scattering into the pipe jacking machine. The water inlet pipe 25 can inject high-pressure water in real time, mixing it with the slag to form a mud-water mixture. The discharge pipe 2... 6. The pretreated mud-water mixture is stably transported to the mud-water treatment tank 5 through the mud-water pump pipeline connected to the feed pipe 51. The geared motor 55 outputs low speed and high torque power to drive the conical crushing screw 54 to rotate. The conical crushing screw 54 adopts a conical variable diameter design. The feed end has a large screw pitch and wide diameter to accommodate the slag after primary crushing. The discharge end has a small screw pitch and narrow diameter. Through spiral extrusion and shearing, the slag is further crushed to achieve the goal of graded crushing. This solves the problem that the traditional fixed tooth assembly cannot dynamically adapt to the slag particle size. At the same time, it ensures that the crushed slag is uniform, which provides a guarantee for smooth subsequent mud discharge.
[0019] Example 2: Figure 1 - Figure 3 As shown, a discharge pipe 52 is connected through the bottom surface of the mud and water treatment tank 5. The interior of the discharge pipe 52 is connected to the interior of the crushing tank 53. The bottom end of the feed pipe 51 is connected through the inner wall of the mud and water treatment tank 5 and the interior of the crushing tank 53. An electrical control box 4 is installed on the outer wall of the pipe jacking machine frame 1. A deflection seat 3 is installed on the bottom surface of the pipe jacking machine frame 1. The deflection seat 3 includes a connecting plate 31, a rotating frame 32, a base 33, a hydraulic cylinder 1 34, and a hydraulic cylinder 2 35. The connecting plate 31 is installed on the top surface of the base 33. The rotating frame 32 is rotatably connected to the top surface of the connecting plate 31. One end of the hydraulic cylinder 1 34 is rotatably connected to the end of the connecting plate 31. The end of the telescopic rod of the hydraulic cylinder 1 34 is rotatably connected to the outer wall of the rotating frame 32. One end of the pipe jacking machine frame 1 is rotatably connected to the top surface of the rotating frame 32. The hydraulic cylinder 2 35 is installed between the side wall of the pipe jacking machine frame 1 and the rotating frame 32.
[0020] The overall effect of this embodiment is that the discharge pipe 52 penetrates the bottom surface of the mud and water treatment tank 5 and is connected to the crushing tank 53, which can directly discharge the fine particle mud and water mixture after secondary crushing, avoiding the accumulation of slag in the crushing tank 53. Its design in conjunction with the conical crushing screw 54 improves the mud discharge efficiency. The deflection seat 3, through the coordinated action of the connecting plate 31, the rotating frame 32, the base 33, the hydraulic cylinder 1 34 and the hydraulic cylinder 2 35, realizes the flexible adjustment of the angle of the pipe jacking machine. When the hydraulic cylinder 1 34 extends or retracts, it can drive the rotating frame 32 to rotate around the connecting plate 31, realizing the horizontal deflection of the pipe jacking machine. When the hydraulic cylinder 2 35 extends or retracts, it can drive the pipe jacking machine frame 1 to rotate around the rotating frame 32, realizing the vertical deflection of the pipe jacking machine.
[0021] The operating method and working principle of this device are as follows: By fixing the base 33 to the construction platform, the deflection seat 3 is started through the electrical control box 4, which controls the extension and retraction of hydraulic cylinder 1 34 and hydraulic cylinder 2 35, adjusting the angle of the pipe jacking machine frame 1 and the cutter head 23 to align them with the construction hole position; the sealing of the pipeline connection between the water inlet pipe 25, the drain pipe 26 and the feed pipe 51 is checked to ensure the normal operation of the mud pump; the motor drive mechanism 21 is started through the electrical control box 4, which drives the transmission rod 22 and the cutter head 23 to rotate, and at the same time the pipe jacking propulsion mechanism 2 is started, driving the motor drive mechanism 21 and the cutter head 23 to advance into the stratum, and the cutter head 23 completes the first-stage coarse crushing; the valve of the water inlet pipe 25 is opened to inject high-pressure water to mix with the coarse crushed slag in the discharge box 24 to form a mud-water mixture; the mud pump is started, and the mud-water mixture is transported to the crushing box 53 of the mud-water treatment box 5 through the drain pipe 26 and the feed pipe 51; the reduction motor 55 is started to drive the conical crushing screw 54 to rotate, and the slag in the mud-water mixture is subjected to secondary fine crushing.
