Description

Technical Field

[0001] The invention relates to the technical field of river channel desilting, and in particular to a river channel regulation silt removal and processing device. Background Art

[0002] The accumulation of river silt will cause a series of negative effects, such as water flow obstruction, increased water surface fluctuations, eutrophication of water bodies, etc. In severe cases, it may even cause environmental pollution. Therefore, the silt needs to be cleaned regularly. Generally, a grab bucket is used to grab the silt from the river to the shore, and then the silt is solidified by spontaneous combustion and air drying or chemical solidification for subsequent treatment.

[0003] When using a curing agent to treat silt, a grab bucket is usually used to grab the silt to the shore and then the curing agent is thrown on it. The silt accumulates on the ground. If the curing agent is thrown from the top, the curing agent can contact the silt on the top layer, but it is difficult to contact and react with the silt accumulated on the bottom layer. In addition, it is inconvenient to manually sprinkle the curing agent on the silt after the silt is grabbed to the ground. In general, cement ash is used as a curing agent to treat the silt. When the cement ash is stored for a long time, it may come into contact with moisture in the air and cause it to clump. When the clumped cement ash comes into contact with the silt, it will affect the mixing effect of the cement ash and the silt. At the same time, when the grab bucket grabs the silt, if the silt has a low water content, some of the silt will adhere to the inner wall of the grab bucket when it is dumped. The silt grabbing effect is not good, and the overall silt removal and treatment effect needs to be further improved. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention is provided with a material box. When the grab bucket body grabs the sludge, the curing agent in the material box can be sprayed into the inside of the grab bucket body. At the same time, the material stirring and spreading component can expand the spreading range of the curing agent. While the material stirring and spreading component can expand the spreading range of the curing agent, it can avoid curing agent agglomeration. After the sludge is grabbed, it can be directly solidified inside the grab bucket body. There is no need to dump the sludge at a fixed position after grabbing it and then directly spray the curing agent on the top of the sludge pile, which makes it difficult for the sludge to fully contact and react with the curing agent. The sludge processing steps are simplified. At the same time, when the curing agent is sprayed, the stirring and scraping mechanism can cooperate to fully stir the curing agent and the sludge, thereby improving the mixing of the curing agent and the sludge. The effect can improve the overall solidification effect. At the same time, when grabbing sludge, the water immersion detection mechanism can detect the position of the grab bucket body in real time to detect the state of the grab bucket body. When the water immersion detection mechanism detects that the grab bucket body is in the sludge grabbing state, the material box is closed. When the water immersion detection mechanism detects that the grab bucket body is out of water after grabbing the mud, the curing agent is sprayed, and the detection and feeding mechanism can be used to detect the remaining curing agent in the material box. When the water immersion detection mechanism detects that the grab bucket body is in the material discharging state, the stirring and scraping mechanism is controlled to cooperate with the material discharging and the inner wall of the grab bucket is cleaned at the same time to avoid sludge adhesion affecting the later sludge grabbing effect and improve the overall sludge removal effect.

[0021] The present invention is provided with a stirring and scraping mechanism. The scraping plate cooperates with the synchronous distance measuring component to rotate to scrape the sludge attached to the inner wall of the grab bucket, thereby accelerating the material feeding speed and improving the material feeding effect. At the same time, the stirring blade can cooperate with the sludge and curing agent inside the grab bucket to stir and mix the sludge and curing agent, thereby improving the mixing effect of the sludge curing agent.

[0022] The present invention is provided with a synchronous distance measuring component. When the water immersion detection mechanism detects that the grab bucket body is in a discharging state, the stirring and scraping mechanism can be switched to clean the inside of the grab bucket body. While the scraping plate is driven by the connecting shaft to rotate and contact the inner wall of the grab bucket body to scrape the sludge inside, the contact shaft contacts the inner wall of the grab bucket body under the action of the spring, and cooperates with the distance sensor and the detection block to judge the distance between the connecting shaft and the inner wall of the grab bucket body, and adjusts the scraping plate to move to fit the inner wall of the grab bucket body according to the reflected distance value, so as to ensure the scraping effect of the scraping plate on the sludge.

[0023] The present invention is provided with a material stirring and diffusion component. When it is detected that the grab bucket body is out of the water surface, the control valve on the discharge pipe is opened to spray the curing agent into the grab bucket body. Synchronously, the second gear rotates to drive the evacuation blade to rotate inside the material box to achieve the stirring operation of the curing agent, thereby avoiding the agglomeration of the curing agent and affecting the subsequent mixing effect of the curing agent and the sludge. At the same time, when the second gear rotates, it meshes with the first gear to drive the movable rotating plate to rotate synchronously when the curing agent is sprayed, thereby driving the movable rotating plate to rotate at the discharge port on the material box, thereby expanding the spraying range of the curing agent and avoiding the problem of blockage at the discharge port on the material box.

[0024] The present invention is provided with a detection and feeding mechanism. When it is detected that the grab bucket body is out of the water, the hydraulic telescopic rod for driving the supporting frame is started to drive the supporting frame to move downward until it is separated from the top frame. At this time, the top frame is no longer supported by the supporting frame, and the material box is lifted up as a whole by the pull rope. The tension sensor is subjected to the downward pulling force of the material box, and the pulling force can reflect the remaining curing agent inside the material box. When it is detected that the remaining curing agent inside the material box is insufficient, the grab bucket body is moved as a whole to the curing agent feeding position, and the telescopic feeding pipe is connected with the feeding pipe at the external feeding position to perform the feeding operation. If the pulling force reflects that the remaining curing agent inside the material box is sufficient, the supporting frame is moved up and reset to support the top frame, so as to replenish the curing agent inside the material box in time.

[0025] The present invention is provided with a water immersion detection mechanism. When preparing to grab the sludge, the grab bucket body moves to the upper side of the water surface and opens to both sides. While opening, the rotating frame rotates to drive the touch block to rotate and contact the inner trigger switch to trigger it. After the trigger switch is triggered, the water immersion sensor is controlled to move downward into the water to judge the water surface. When the water surface is detected, it means that the grab bucket body is in a state of preparing to grab the sludge, so the material box is controlled to be closed. When the grab bucket body finishes grabbing the sludge, the rotating frame rotates and triggers the trigger switch again. At this time, the water immersion sensor can judge whether it is out of the water surface. Once it is detected that it is out of the water surface, the material box is opened to perform sludge solidification processing. After solidification, when preparing for unloading, the grab bucket body opens and the rotating frame rotates again to trigger the trigger switch. At this time, the water immersion sensor detects that the grab bucket body is in a unloading state, so the scraper plate is controlled to switch to scraping the sludge from the inner wall of the grab bucket to assist unloading.

The torsion spring 913 is sleeved on the rotating shafts at both ends of the movable touch plate 911, one end of the torsion spring 913 is fixedly connected to the rotating frame 91, two trigger switches 912 are fixedly installed on both ends of the movable touch plate 911, the trigger switch 912 is electrically connected to the external controller, the mounting seat 93 is fixedly installed on the rotating frame 91, the water immersion sensor 931 (ZK-WLD1) is movably installed on the mounting seat 93, the water immersion sensor 931 is driven by a hydraulic telescopic rod, the water immersion sensor 931 is electrically connected to the external controller, an external box for installing the water immersion sensor 931 is fixedly installed on the mounting seat 93, and the movable guard plate 932 is movably installed on the water immersion sensor At the bottom of the water sensor 931, the movable guard plate 932 is driven by a hydraulic telescopic rod, and the hydraulic telescopic rod is electrically connected to the external controller. When the water sensor 931 is not detecting, the movable guard plate 932 can be moved to the bottom of the water sensor 931 to shield and protect it; by providing a water immersion detection mechanism 9, when preparing to grab the sludge, the grab bucket body 4 moves to the upper side of the water surface, and the grab bucket body 4 opens to both sides. At the same time, the rotating frame 91 rotates to drive the touch block 921 to rotate and contact the trigger switch 912 to trigger it. After the trigger switch 912 is triggered, the water sensor 931 is controlled to move downward into the water to judge the water surface. When the detection When the water surface is detected, it means that the grab bucket 4 is in a state of preparing to grab the sludge, and the material box 7 is controlled to be closed. When the grab bucket 4 finishes grabbing the sludge, it rotates through the rotating frame 91 and triggers the trigger switch 912 again. At this time, the water immersion sensor 931 can judge whether it is out of the water surface. Once it detects that it is out of the water surface, the material box 7 is opened to perform the sludge solidification treatment operation. After solidification, when preparing for unloading, the grab bucket 4 is opened and rotated through the rotating frame 91 again to trigger the trigger switch 912. At this time, the water immersion sensor 931 detects that the grab bucket 4 is in a unloading state, and the scraper plate 413 is controlled to switch to scrape the sludge from the inner wall of the grab bucket 4 to assist in unloading.

[0044] When the present invention is used, when clearing river silt, the vehicle body is used to carry the crane 1 as a whole and move it to the shore to prepare for the silt grabbing operation. After the silt is located, the crane 1 is started to move the grab bucket body 4 to the upper side of the silt position to prepare for the silt grabbing operation. At this time, the material box 7 is filled with a curing agent for curing the silt.

[0045] When it moves to the water surface position on the upper side of the silt, the grab bucket body 4 is driven to open through the external controller, and the two grab bucket bodies 4 are opened to both sides. When the grab bucket bodies 4 rotate and open, the rotating frame 91 rotates on the connecting column 92, and synchronously, the touch block 921 and the movable touch plate 911 contact each other and touch the trigger switch 912 to trigger it. At this time, the hydraulic telescopic rod used to drive the water immersion sensor 931 starts to drive the water immersion sensor 931 to move downward into the water. When the water immersion sensor 931 moves downward, the movable guard plate 932 The water sensor 931 is withdrawn to one side to ensure that the water sensor 931 can be lowered into the water. When the water sensor 931 enters the water, it will sense the presence of water and send a prompt to the controller, indicating that this is the water surface. At this time, the water sensor 931 rises and retracts, and the controller controls the control valve on the feed pipe 71 to close, so as to prevent the water in the river from entering the material box 7 when the silt is captured, causing cement agglomeration. The grab bucket body 4 enters the water to capture the silt. After the silt is captured, the grab bucket body 4 rotates to close and moves upward out of the water.

[0046] When the grab bucket body 4 grabs the sludge and closes, the rotating frame 91 rotates on the connecting column 92, and the touch block 921 touches the trigger switch 912 on the movable touch plate 911 again to trigger it, and the water immersion sensor 931 descends again for detection. When the crane 1 lifts the grab bucket body 4 out of the water, the water immersion sensor 931 can detect the water surface. When the water surface cannot be detected, it means that the grab bucket body 4 has left the water. At this time, the hydraulic telescopic rod used to drive the supporting bracket 85 starts to drive the supporting bracket 85 to move downward to separate from the top frame 84. At this time, the top frame 84 is no longer supported by the supporting bracket 85, and the material box 7 is lifted up by the pull rope 83 as a whole. Since the material box 7 is arranged on the upper side of the grab bucket body 4, when the grab bucket body 4 grabs the sludge, When leaving the water surface, the silt and water in the grab bucket body 4 can overflow from the gaps on the grab bucket body 4 and the gaps at the bottom, and there is a certain distance between the bottom of the feed pipe 71 and the highest point of the grab bucket body 4 to ensure that the bottom of the feed pipe 71 will not contact the silt in the grab bucket body 4. The tension sensor 82 is subjected to the downward pulling force of the material box 7, and the pulling force can reflect the remaining amount of curing agent inside the material box 7. When it is detected that the remaining amount of curing agent inside the material box 7 is insufficient, the grab bucket body 4 is moved as a whole to the curing agent feeding place, and the telescopic feeding pipe 87 is connected to the feeding pipe at the external feeding place for feeding operation. If the pulling force reflects that the remaining amount of curing agent inside the material box 7 is sufficient, the support frame 85 moves up and resets and supports the top frame 84, and the material box 7 is reset at this time;

[0047] After 7 is reset, the control valve on the discharge pipe 71 is opened synchronously. At the same time as the control valve is opened, the second gear 73 rotates to drive the evacuation blade 76 to rotate to stir the curing agent inside the material box 7. The curing agent is made of cement. When the evacuation blade 76 stirs, the curing agent can be stirred and broken to avoid cement agglomeration. Synchronously, when the second gear 73 rotates, it meshes with the first gear 72 to drive the first gear 72 to rotate synchronously. When the first gear 72 rotates, it drives the movable rotating plate 74 to rotate at the discharge port on the material box 7. When the movable rotating plate 74 rotates, it can expand the downward spraying range of the curing agent and avoid blockage at the discharge port on the material box 7. When the material box 7 is discharging, the connecting shaft 411 rotates and drives the stirring blade 414 to stir the sludge and curing agent in the grab bucket body 4, thereby improving the mixing effect of the curing agent and the sludge. When the curing agent is sprayed, the material box 7 stops discharging, and the stirring blade 414 rotates and resets to prepare for the sludge pouring operation.

[0048] The two grab bucket bodies 4 are opened to both sides, ready for unloading. Synchronously, the rotating frame 91 rotates on the connecting column 92, the trigger switch 912 is triggered again, and the water immersion sensor 931 extends downward to detect the water surface. At this time, the water surface cannot be detected, and the grab bucket body 4 is in an open state, which means that the unloading operation is ready. The synchronous external servo motor drives the connecting shaft 411 to rotate, and the distance sensor 422 is started. While the connecting shaft 411 rotates, the contact shaft 426 can contact the inner wall of the grab bucket body 4 and reflect the distance between the connecting shaft 411 and the inner wall of the grab bucket body 4 through the cooperation of the distance sensor 422 and the detection block 423. The hydraulic telescopic rod is adjusted by the feedback distance difference to drive the stirring blade 414 to move to a position in contact with the inner wall of the grab bucket body 4, so as to achieve the scraping of the inner wall of the grab bucket body 4 by the stirring blade 414 while the grab bucket body 4 is unloading, thereby accelerating the speed of sludge unloading, and at the same time, the inner wall of the grab bucket body 4 can be cleaned to provide a sludge effect.
