Description

Technical Field

[0001] The utility model relates to the technical field of silting removal in water conservancy construction, and in particular to a high-efficiency silting removal device in water conservancy construction. Background Art

[0002] River dredging generally refers to the management of river channels, which belongs to water conservancy projects. There are many ways to dredge the river, and the main methods are divided into dry water operations, water operations and environmental dredging. Water operations use high-pressure water guns of hydraulic flushing and excavation units to flush the bottom mud, disturbing the bottom mud into mud. The flowing mud gathers in the low-lying areas set up in advance, and is sucked up by mud pumps and transported through pipelines to the storage yard or slurry collection pool on the shore.

[0003] After the silt and water are pumped into the sludge collecting box, the presence of water will affect the volume of the sludge collected by the sludge collecting box. At the same time, after the silt and water are discharged to the ground at the same time, it takes a long time for the water in the sludge to dissipate, which makes the dredging efficiency slow. Now a high-efficiency dredging device for water conservancy construction is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency water conservancy construction silt removal device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A high-efficiency desilting device for water conservancy construction comprises a material guiding mechanism, a separation mechanism is arranged inside the material guiding mechanism, and a crushing mechanism is fixedly connected to one end of the separation mechanism.

[0007] The separation mechanism includes a first drive motor, an output end of which is fixedly connected to a limit rod, one end of which is fixedly connected to a separation box, an electric push rod is fixedly connected to the interior of the separation box, and a silt pushing plate is fixedly connected to the telescopic end of the electric push rod.

[0008] A further improvement of the technical solution of the utility model is that: a water outlet is provided on the separation box, a filter is fixedly connected to the water outlet, and a silt discharge port is provided on the separation box. Water in the silt is filtered by the filter and then discharged from the water outlet, and the silt is blocked by the filter and remains in the separation box, so that water and silt are separated.

[0009] A further improvement of the technical solution of the utility model is that a first box door is hinged at the silt discharge port of the separation box, one end of the separation box is rotatably connected to a silt extraction pipe, a silt extraction pump is provided on the silt extraction pipe, and when the silt extraction pump is running, silt can be extracted into the separation box through the silt extraction pipe.

[0010] A further improvement of the technical solution of the utility model is that: the material guiding mechanism includes a shell, the first driving motor is fixedly connected to the left side of the shell, the limiting rod is rotatably connected to the inside of the shell, one end of the separation box is rotatably connected to the inside of the shell, the silt extraction pipe is fixedly connected to one side of the shell, and the first driving motor is running to drive the separation box to rotate through the limiting rod, thereby separating water and silt.

[0011] A further improvement of the technical solution of the utility model is that a material guide plate is fixedly connected to the inside of the shell, a discharge port is opened on the shell, a second box door is hinged on the discharge port, and a drain pipe is fixedly connected to the inside of the shell. The dried sludge slides into the discharge port along the material guide plate, thereby preventing the sludge from falling into the shell, thereby avoiding the need for secondary cleaning.

[0012] A further improvement of the technical solution of the utility model is that the crushing mechanism includes a pipeline, the pipeline is fixedly connected to the silt extraction pipe, a second drive motor is fixedly connected to the pipeline, the output end of the second drive motor is fixedly connected to a connecting rod, and the silt is sucked into the pipeline under the drive of the silt extraction pipe.

[0013] A further improvement of the technical solution of the utility model is that: a crushing knife is fixedly connected to one end of the connecting rod, a spring is fixedly connected to the connecting rod, one end of the spring is fixedly connected to a connecting shell, a blade is rotatably connected to the connecting shell, and the crushing knife and the blade cooperate to perform secondary crushing of the sludge, thereby preventing the sludge from clogging the silt extraction pipe.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. Compared with the prior art, the beneficial effects of the utility model are as follows: the silt extraction pump is started, and the silt is extracted into the separation box through the silt extraction pipe, and then the first driving motor is started, and the separation box is driven to rotate through the limit rod. The separation box generates centrifugal force due to the rotation of its interior, thereby swinging the silt, and the water in the silt is filtered by the filter screen and discharged from the water outlet, and the silt is blocked by the filter screen and remains in the separation box. After the dredging is completed, the first box door is opened, and the electric push rod is started to drive the silt pushing plate to move. After the silt is pushed into the first box door, the silt can be cleaned. The water and silt are separated in the whole process, and then the silt is cleaned centrally, thereby achieving the purpose of improving the efficiency of dredging.

[0016] 2. Compared with the prior art, the beneficial effects of the utility model are as follows: the second driving motor is started, and the connecting rod is rotated to drive the crushing knife to rotate, so that the sludge is initially crushed. The centrifugal force generated when the connecting rod rotates swings the connecting shell and the blade outward. Driven by the spring, the moving position of the blade is limited, which can prevent the blade and the connecting shell from falling off. The sludge passes through the blade and can be crushed for the second time. When the sludge enters the pipeline, it can prevent the silt extraction pipe from being blocked during operation.

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with the embodiments:

[0023] Example 1

[0024] like Figure 1-4As shown, the utility model provides a high-efficiency desilting device for water conservancy construction, including a material guiding mechanism 2, a separation mechanism 1 is arranged inside the material guiding mechanism 2, one end of the separation mechanism 1 is fixedly connected to a crushing mechanism 3, the separation mechanism 1 includes a first driving motor 11, the output end of the first driving motor 11 is fixedly connected to a limiting rod 12, one end of the limiting rod 12 is fixedly connected to a separation box 13, an electric push rod 14 is fixedly connected inside the separation box 13, a silt pushing plate 15 is fixedly connected to the telescopic end of the electric push rod 14, a water outlet 16 is provided on the separation box 13, a filter screen 17 is fixedly connected to the water outlet 16, a silt discharge port is provided on the separation box 13, a first box door 18 is hinged at the silt discharge port of the separation box 13, one end of the separation box 13 is rotatably connected to a silt extraction pipe 19, and a silt extraction pump 10 is arranged on the silt extraction pipe 19;

[0025] Specifically, the silt extraction pump 10 is started, and the silt is pumped into the separation box 13 through the silt extraction pipe 19. Then, the first drive motor 11 is started, and the separation box 13 is driven to rotate through the limit rod 12. The separation box 13 generates centrifugal force due to the rotation of its interior, thereby swinging the silt. The water in the silt is filtered by the filter screen 17 and discharged from the water outlet 16. The silt is blocked by the filter screen 17 and remains in the separation box 13. After dredging is completed, the first box door 18 is opened, and the electric push rod 14 is started to drive the silt pushing plate 15 to move. After the silt is pushed into the first box door 18, the silt can be cleaned, thereby improving the efficiency of dredging.

[0026] Example 2

[0027] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the material guiding mechanism 2 includes a shell 21, the first driving motor 11 is fixedly connected to the left side of the shell 21, the limit rod 12 is rotatably connected to the inside of the shell 21, one end of the separation box 13 is rotatably connected to the inside of the shell 21, the sludge extraction pipe 19 is fixedly connected to one side of the shell 21, the inside of the shell 21 is fixedly connected with a material guiding plate 22, the shell 21 is provided with a discharge port 23, the discharge port 23 is hinged with a second box door, and the inside of the shell 21 is fixedly connected with a drainage pipe 24;

[0028] Specifically, after the spun dried sludge is pushed out of the first box door 18 by the silt pushing plate 15, it is discharged from the discharge port 23 along the guide plate 22, which is convenient for centralized cleaning of the sludge and can prevent the sludge from falling into the interior of the outer shell 21, thereby avoiding the need for a second cleaning. The sludge is thrown out and discharged into the river channel again through the drain pipe 24.

[0029] Example 3

[0030] like Figure 1-4As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the crushing mechanism 3 includes a pipeline 31, the pipeline 31 is fixedly connected to the silt extraction pipe 19, a second drive motor 32 is fixedly connected to the pipeline 31, a connecting rod 33 is fixedly connected to the output end of the second drive motor 32, one end of the connecting rod 33 is fixedly connected to a crushing knife 34, a spring 35 is fixedly connected to the connecting rod 33, one end of the spring 35 is fixedly connected to a connecting shell 36, and a blade 37 is rotatably connected to the connecting shell 36;

[0031] Specifically, when the silt extraction pump 10 extracts the silt, the second drive motor 32 is started, and the connecting rod 33 is rotated to drive the crushing knife 34 to rotate, thereby performing initial crushing of the silt. The centrifugal force generated when the connecting rod 33 rotates swings the connecting shell 36 and the blade 37 outward. Driven by the spring 35, the moving position of the blade 37 is restricted, which can prevent the blade 37 and the connecting shell 36 from falling off. The silt passes through the blade 37 and is crushed for the second time. When the silt enters the pipeline 31, it can prevent the silt extraction pipe 19 from being blocked during operation.

[0032] The following is a detailed description of the working principle of this highly efficient water conservancy construction dredging device.

[0033] like Figure 1-4 As shown, the second drive motor 32 and the silt extraction pump 10 are started to extract the silt into the pipe 31, and the connecting rod 33 is rotated to drive the crushing knife 34 to rotate, so that the silt is initially crushed. The centrifugal force generated by the rotation of the connecting rod 33 swings the connecting shell 36 and the blade 37 outward. Driven by the spring 35, the moving position of the blade 37 is limited to prevent the blade 37 and the connecting shell 36 from falling. The silt passes through the blade 37 and is crushed for the second time. The crushed silt enters the silt extraction pipe 19 and then enters the separation box 13. The first drive motor 11 is started to drive the separation box 13 through the limit rod 12. The separation box 13 rotates, and the centrifugal force generated by the rotation of its interior is used to swing the silt. The water in the silt is filtered by the filter screen 17 and discharged from the water outlet 16, and then discharged into the river through the drain pipe 24. The silt is blocked by the filter screen 17 and remains in the separation box 13. After dredging is completed, the first box door 18 is opened, and the electric push rod 14 is started to drive the silt pushing plate 15 to move, pushing the silt onto the guide plate 22, and then discharged from the discharge port 23 along the guide plate 22, so as to facilitate the centralized cleaning of the silt, and at the same time, it can prevent the silt from falling into the inside of the outer shell 21, thereby avoiding the need for a second cleaning.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
