Description

Technical Field

[0001] The present invention belongs to the technical field of silt, sand and stone excavation and conveying devices, and specifically refers to a silt, sand and stone excavation and conveying device and its use method. Background Art

[0002] Over time, many slow-flowing rivers and stagnant lakes will form silt layers at the bottom of the water body, which not only cause problems such as black odor and blue-green algae, but also affect the function of flood control and waterlogging prevention. Therefore, regular dredging work must be carried out on river channels and lakes. During the dredging process, it is often necessary to pump the silt to the shore, and sometimes it is also necessary to pump the water to the shore together. However, the existing silt, sand and stone excavation and conveying devices mainly have the following problems:

[0003] A: Existing silt, sand and stone excavation and conveying devices usually use water pumps to completely drain the silt, sand and stone and water in the river channel. However, due to the long conveying distance of the silt, sand and stone and water mixture after suction, if it is conveyed through pipelines, it is easy to cause blockage of the suction pipeline, and the work done to pump the water up may be useless. Therefore, solid-liquid separation generally needs to be carried out on the surface of the river water.

[0004] B: Due to the different silt, sand and stone conditions in different waters, when the existing silt, sand and stone excavation and conveying devices use conveyor belts to transport the extracted silt, sand and stone mixture, the amount of sand and stone conveyed by the conveyor belt each time is unstable and uncontrollable, the transmission efficiency is low, and the mechanical equipment wears out quickly.

[0005] C: Since the weight of the silt, sand and stone after filtering the extracted silt, sand and stone and water mixture cannot be determined, the existing silt, sand and stone excavation and conveying devices cannot adjust the conveyor belt transportation progress according to the actual situation of the silt, sand and stone after filtering and draining water.

[0006] D: Using a conveyor belt to transport silt, sand and stone is easy to slide off from both sides, which is not conducive to collecting silt, sand and stone. Summary of the Invention

[0007] In view of the above situation, to overcome the defects of the prior art, the present invention provides a silt, sand and gravel excavation and conveying device and a method for using the device. Aiming at the problem that the existing silt, sand and gravel excavation and conveying device cannot adjust the conveyor belt transportation progress according to the actual situation of the silt, sand and gravel after pumping and filtering, the gravity feedback principle is creatively applied. Through the gravity feedback self-driving device provided, without any induction module and control module, only through the mechanical structure set, the technical effect that the silt, sand and gravel excavation and conveying device can limit the weight of the silt, sand and gravel after filtering water per single transportation and self-drive the transportation is achieved, solving the technical problem of adjusting the transportation progress according to the weight of the silt, sand and gravel, which is difficult to solve in the prior art. Through the setting of the downward pressure driven gear and the fixed main driving gear, the independent conveyor driving device is greatly simplified, effectively avoiding the problem of using a large number of electric mechanisms and generating high costs. At the same time, through the cooperation of the arc-shaped sliding and tilting mechanism and the roller-type conveying and filtering mechanism, the technical effect of fully filtering the pumped silt, sand and gravel water mixture during the conveying process is achieved. Through the simplified integrated mixing and suction mechanism, the extraction and short-distance transportation of the silt, sand and gravel water mixture are completed, avoiding the blockage of the pipeline. In addition, the silt, sand and gravel excavation and conveying assembly component set in the present invention can prevent the silt, sand and gravel from slipping off the conveying device, thereby improving the working efficiency of the device to a certain extent.

[0008] The technical solutions adopted by the present invention are as follows: The present invention provides a silt, sand and gravel excavation and conveying device, including a gravity feedback self-driving device, an arc-shaped sliding and tilting mechanism, a roller-type conveying and filtering mechanism, an integrated mixing and suction mechanism, and a silt, sand and gravel excavation and conveying assembly component.

The reset buffer damping ring is arranged on the gravity feedback self-driving hinge rotating shaft, and the reset buffer damping ring has a buffering function.

The gravity load-bearing induction plate is used to sense the weight of the silt and sand on the roller-type conveying and water filtering mechanism. When the weight of the silt and sand increases, it will press down the gravity load-bearing induction plate, so that the pressing-driven gear meshes with the integrated mixed suction mechanism through the movement of the gravity feedback self-driving L-shaped cantilever rod, and then drives the lower main rotating drum to roll, driving the roller-type conveying and water filtering mechanism to transport. At the same time, since the silt and sand on the roller-type conveying and water filtering mechanism gradually transfer and its weight decreases, under the reset function of the gravity self-feedback reset torsion spring and the buffering function of the reset buffer damping ring, the gravity feedback self-driving L-shaped cantilever rod gradually rises, and the upper limit baffle has the function of limiting the rising position of the gravity feedback self-driving L-shaped cantilever rod.

When the hinged opening and closing filter screen moves to the lower main rotating roller along with the circulating rotating conveyor belt, the horizontally placed filter screen blocking rod will block the hinged opening and closing filter screen and slide in the moving rod limiting arc-shaped groove along with the hinged opening and closing filter screen, so that the silt, sand and gravel can be filtered through the hinged opening and closing filter screen. When the hinged opening and closing filter screen sinks to the limited value due to the weight of the silt, sand and gravel, the horizontally placed filter screen blocking rod will roll away from the block of the hinged opening and closing filter screen through the filter screen tilting and blocking roller. At the same time, due to the loss of the block of the hinged opening and closing filter screen, the horizontally placed filter screen blocking rod will return to the initial position under the reset action of the arc-shaped sliding and tilting return torsion spring.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows:

[0018] (1) In order to simplify the structure and reduce the production and use costs, the present invention rationally utilizes the weight of the silt and gravel on the conveying device and creatively applies the principle of gravity feedback. By setting a gravity feedback self-driving device, it is possible to determine the conveying drive start time according to the weight of the silt and gravel. In the absence of any sensing module and control module, only the mechanical structure is set to achieve the technical effect that the conveying structure can limit the weight of the silt and gravel transported in a single time, thereby avoiding transportation losses;

[0019] (2) In order to solve the problem that the existing silt and gravel excavation and conveying device cannot adjust the conveyor belt transportation progress according to the actual situation of silt and gravel after water extraction and filtration, a gravity feedback self-driven L-shaped cantilever rod and a gravity load-bearing sensor plate are set up, which can generate a downward displacement according to the weight of the silt and gravel, and then start the conveying device through the engagement of the set downward pressure driven gear and the fixed main drive gear, which not only realizes single quantitative transmission but also greatly simplifies the independent drive device used for transmission;

[0020] (3) The gravity self-feedback reset torsion spring is set to store the torque generated by the displacement of the gravity feedback self-driven transmission mechanism, and then produce a reset effect when the weight of the silt and gravel gradually decreases after being transported by the conveyor belt. Through the cooperation of the reset buffer damping ring and the upper limit baffle, the reset process of the gravity feedback self-driven transmission mechanism is buffered and the reset height is limited;

[0021] (4) In order to better improve the effect of filtering the silt, sand, gravel and water mixture, the arc-shaped sliding tilting mechanism and the roller-type conveying and filtering mechanism are combined to achieve the technical effect of fully filtering the extracted silt, sand, gravel and water mixture during the conveying process;

[0022] (5) The setting of the conveyor belt fit reset torsion spring makes the hinged opening and closing filter have the tendency to fit the circulating rotating conveyor belt, which helps the silt and gravel to be discharged into the land silt and gravel storage frame by the rotating roller at the upper position;

[0023] (6) Without any intervention of electrical equipment, by placing the filter screen retaining rod horizontally and setting the movable rod limiting arc groove, the hinged opening and closing filter screen is gradually opened at the lower main rotating drum during the conveying process, thereby facilitating the full filtration of the silt, sand and water mixture;

[0024] (7) The integrated mixing and suction mechanism is used to extract and transport the silt, sand, gravel and water mixture over short distances, thus avoiding pipeline blockage.

[0025] The (8) silt, sand and gravel excavation, transportation and assembly component can prevent silt, sand and gravel from slipping off the conveying device during the conveying and transportation process, thereby improving the working efficiency of the device to a certain extent.

[0051] Then, as the accumulation of sludge and sand increases, the weight of the sludge and sand increases, continuously pressing down on the gravity load-bearing induction plate 17 and causing the gravity self-feedback reset torsion spring 15 to twist. Furthermore, through the movement of the gravity feedback self-driven L-shaped cantilever rod 14, the downward pressure driven gear 11 meshes with the fixed main drive gear 38, thereby driving the lower main rotating drum 10 to roll and driving the circulating rotating conveyor belt 26 to rotate upward to transport the sludge and sand. At the same time, since the sludge and sand on the circulating rotating conveyor belt 26 gradually shift and its weight decreases, under the reset action of the gravity self-feedback reset torsion spring 15 and the buffering action of the reset buffer damping ring 16, the gravity feedback self-driven L-shaped cantilever rod 14 gradually rises to the initial position. The upper limit baffle 18 has the function of restricting the rising position of the gravity feedback self-driven L-shaped cantilever rod 14, and the downward pressure driven gear 11 terminates meshing with the fixed main drive gear 38, and the roller-type water filtering mechanism 3 stops conveying;

[0052] At the same time, since the initial position of the horizontally placed filter screen blocking rod 24 is at the bottom of the moving rod limiting arc groove 21, when the articulated opening and closing filter screen 29 moves to the lower main rotating drum 10 along with the circulating rotating conveyor belt 26, the horizontally placed filter screen blocking rod 24 will block the articulated opening and closing filter screen 29 and slide along with the articulated opening and closing filter screen 29 in the moving rod limiting arc groove 21, so that the extracted sludge, sand, and water mixture can be filtered through the articulated opening and closing filter screen 29. When the articulated opening and closing filter screen 29 sinks to the limit value due to the weight of the sludge and sand, the horizontally placed filter screen blocking rod 24 will block the rolling of the filter screen tilting blocking roller 25 to break away from the blocking of the articulated opening and closing filter screen 29. At the same time, due to the loss of the blocking of the articulated opening and closing filter screen 29, the horizontally placed filter screen blocking rod 24 will return to the initial position under the reset action of the arc sliding tilting reset torsion spring 23;

[0053] In addition, at the upper rotating drum 7, due to the rolling of the circulating rotating conveyor belt 26, the sludge and sand roll into the land sludge and sand storage frame 39, and the articulated opening and closing filter screen 29 returns to the state of fitting the circulating rotating conveyor belt 26 under the limiting action of the conveyor belt fitting reset torsion spring 30;

[0054] The above is the overall working process of the present invention. Just repeat these steps the next time it is used.

7. A method for using the silt and gravel excavation and conveying device according to claim 6, characterized in that, It includes the following steps: Step 1: Turn on the suction and transportation combined drive motor (35). The suction and transportation combined drive motor (35) drives the integrated hybrid suction and air pump (32) through the suction and transportation combined drive rotating shaft (36) to extract the sludge, sand and gravel water mixture through the sinking suction pipeline (33) and transport it to the circulating conveyor belt (26) through the upper conveying pipeline (34).

The user can choose to connect a water pump according to the usage situation to pump away the water through the suction drainage port (43) or directly discharge it into the river. Step 3: As the accumulation of silt, sand and gravel increases, the weight of the silt, sand and gravel increases and continuously presses down on the gravity load-bearing induction plate (17), causing the gravity self-feedback reset torsion spring (15) to twist. Then, through the movement of the gravity feedback self-driven L-shaped cantilever rod (14), the downward pressure driven gear (11) meshes with the fixed main drive gear (38), thereby driving the lower main rotating drum (10) to roll and driving the circulating rotating conveyor belt (26) to rotate to transport the silt, sand and gravel upward; Step 4: At the same time, since the silt, sand and gravel on the circulating rotating conveyor belt (26) gradually transfer and its weight decreases, due to the reset function of the gravity self-feedback reset torsion spring (15) and the buffering function of the reset buffer damping ring (16), the gravity feedback self-driven L-shaped cantilever rod (14) gradually rises to the initial position. The upper limit baffle (18) has the function of restricting the rising position of the gravity feedback self-driven L-shaped cantilever rod (14). The downward pressure driven gear (11) terminates meshing with the fixed main drive gear (38), and the roller conveyor water filtering mechanism (3) stops conveying; Step 5: Since the initial position of the horizontally placed filter screen baffle rod (24) is at the bottom of the moving rod limiting arc groove (21), when the hinged opening and closing filter screen (29) moves to the lower main rotating drum (10) along with the circulating rotating conveyor belt (26), the horizontally placed filter screen baffle rod (24) will block the hinged opening and closing filter screen (29) and slide along with the hinged opening and closing filter screen (29) in the moving rod limiting arc groove (21), so that the extracted silt, sand and gravel water mixture can be filtered through the hinged opening and closing filter screen (29); Step 6: When the hinged opening and closing filter screen (29) sinks to the limit value due to the weight of the silt, sand and gravel, the horizontally placed filter screen baffle rod (24) will roll away from blocking the hinged opening and closing filter screen (29) through the filter screen tilting and blocking roller (25). At the same time, due to the loss of the blocking of the hinged opening and closing filter screen (29), the horizontally placed filter screen baffle rod (24) will return to the initial position under the reset action of the arc sliding tilting reset torsion spring (23); Step 7: At the upper rotating drum (7), due to the rolling of the circulating rotating conveyor belt (26), the silt, sand and gravel roll into the land silt, sand and gravel storage frame (39), and the hinged opening and closing filter screen (29) returns to the state of fitting the circulating rotating conveyor belt (26) under the limiting action of the conveyor belt fitting reset torsion spring (30).
