Description

Technical Field

[0001] The present invention relates to the field of wetland operation equipment, and specifically refers to an excavating and sieving device for wetland soil remediation. Background Art

[0002] A wetland refers to a marshland, moorland, peatland or water area, whether natural or artificial, permanent or temporary, with stagnant or flowing, fresh, brackish or saline water bodies, including waters with a water depth not exceeding 6 meters at low tide. It can be divided into natural wetlands and artificial wetlands. Natural wetlands include marshlands, peatlands, lakes, rivers, beaches and salt marshes, etc.; artificial wetlands mainly include reservoirs, ponds, paddy fields, etc.

[0003] Wetlands have a certain self-repair ability, which is an important guarantee for the stability and balance of their ecosystem. The main repair methods are physical filtration and bioremediation. Among them, physical repair is that due to the usually complex particle structure of wetland soil, fine clay, silt and larger sand grains are intertwined with each other to form a natural physical filtration layer. When water flows through the wetland, pollutants such as suspended particles and some heavy metal ions will be adsorbed and intercepted by soil particles and deposited in the soil pores, preventing them from further diffusing into the deep part of the wetland or downstream waters, while purifying the water body and improving the soil texture. Therefore, if there are sundries such as large stones and soil lumps remaining in the surface layer of wetland soil, it will affect the self-repair ability of the wetland, so it needs to be cleaned regularly.

[0004] At present, the method of cleaning large sundries on the surface layer of wetlands is usually to manually excavate and screen them with a cleaning shovel, which is inconvenient to operate; in addition, the manual turning method requires cleaning the excavation shovel once for each turn, and it is impossible to continuously turn the surface soil of the wetland, resulting in low work efficiency.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] In addition, the term "and / or" in this article is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally indicates that the front and rear associated objects are in an "or" relationship.

[0048] As Figure 1 , Figure 2 and Figure 4 shown, the excavating and sieving device for wetland soil remediation includes: a frame 1, an excavating assembly 2, a sieving assembly 3, a supporting comb 4, a housing 5, a motor 6, and a driving mechanism 7. The excavating assembly 2 is rotatably installed on the frame 1, and the rotation of the excavating assembly 2 can shovel up the wet soil, sediment, etc. on the surface layer of the wetland. The sieving assembly 3 is installed in the frame 1. As the excavating assembly 2 rotates, the shoveled wet soil, sediment, etc. are poured into the sieving assembly 3 and sieved. The small particles return to the ground, and the large particles are intercepted to achieve the purpose of cleaning large debris. The supporting comb 4 is installed on the side of the sieving assembly 3 corresponding to the excavating assembly 2. The supporting comb 4 is composed of a number of strip-shaped teeth arranged at equal intervals, and the supporting comb 4 is inclined upward from the sieving groove 31 towards the excavating assembly 2. When the excavating assembly 2 rotates to the overturned state, the large objects in the excavating assembly 2 fall into the sieving assembly 3 under the guidance of the supporting comb 4, and the small sediment will fall back to the ground through the gaps between two adjacent strip-shaped teeth, playing a role of preliminary sieving. The housing 5 is installed on the frame 1, the motor 6 is installed on the housing 5, and the driving mechanism 7 is installed inside the housing 5. When the motor 6 is started, the driving of the driving mechanism 7 can make the excavating assembly 2 rotate and at the same time make the sieving assembly 3 perform a sieving operation on the sediment.

[0049] As Figure 1 , Figure 2 , Figure 3As shown, the excavation assembly 2 includes: a rotating disk 21, a connecting rod 22, an excavation bucket 23, a through groove 24, a drainage port 25 and a shovel tooth 26. There are two rotating disks 21, which are rotatably mounted on both sides of the inner wall of the frame 1, and one of the rotating disks 21 is connected to the driving mechanism 7 to ensure that the driving mechanism 7 can drive the rotating disk 21 connected thereto to rotate. The two ends of the connecting rod 22 are respectively connected to the opposite sides of the two rotating disks 21, so that the two rotating disks 21 and the connecting rod 22 form a whole, ensuring that the two rotating disks 21 can rotate synchronously and stably. The excavation bucket 23 is installed on the connecting rod 22. The excavation bucket 23 is composed of a hollow structure with an open top. Its cross-sectional shape is a fan-shaped setting with an acute central angle. When it rotates, the side away from the connecting rod 22 first contacts the ground surface. As the rotation continues, the wetland surface layer can be excavated and the excavated objects can be supported. There are several through grooves 24, which are respectively opened on the excavating bucket 23. On the one hand, the several through grooves 24 are respectively distributed corresponding to the strip teeth of the supporting comb teeth 4. When the excavating bucket 23 rotates to correspond to the supporting comb teeth 4, the two are intertwined, which can ensure that the wet soil, mud and sand in the excavating bucket 23 are smoothly transferred to the supporting comb teeth 4, while avoiding mutual interference between the two. On the other hand, during the excavation process, the through grooves 24 can allow air to flow smoothly into the excavating bucket 23, reducing the negative pressure caused by the lack of air circulation, so that the wet soil can enter the excavating bucket 23 more easily. There are several drainage ports 25, which are respectively opened on the outer wall of the excavating bucket 23. These drainage ports 25 are evenly distributed. When the excavating bucket 23 shovels up wet soil, excess water can be quickly discharged through the drainage ports 25, effectively preventing the excavation efficiency of the excavating bucket 23 from being affected by excessive water accumulation, and even causing adverse phenomena such as material accumulation. There are several shovel teeth 26, which are respectively installed on the side of the excavator bucket 23 away from the connecting rod 22. The shovel teeth 26 are inverted cone structures. As the excavator bucket 23 rotates, the shovel teeth 26 will first contact the ground. When the shovel teeth 26 cut into the wetland soil, they can smoothly penetrate the soil layer with their sharp front ends, ensuring smooth excavation work.

[0050] like Figure 4 , Figure 5 and Figure 6As shown in the figure, the driving mechanism 7 includes: a first bevel gear 71, a mounting block 72, a rotating shaft 73, a second bevel gear 74, a first gear 77, and a second gear 78. The first bevel gear 71 is rotatably mounted on the frame 1, and the first bevel gear 71 is connected to the excavation assembly 2. Specifically, the first bevel gear 71 and one of the rotating disks 21 can rotate synchronously, so as to ensure that when the first bevel gear 71 rotates, it can drive the entire excavation assembly 2 to rotate. The mounting block 72 is mounted in the housing 5, and the rotating shaft 73 is rotatably connected to the mounting block 72. There are two mounting blocks 72, and the mounting block 72 plays an important role in supporting and fixing other components of the rotating shaft 73, ensuring that the rotating shaft 73 can rotate stably. The second bevel gear 74 is mounted at one end of the rotating shaft 73 close to the first bevel gear 71, and the second bevel gear 74 is meshed with the first bevel gear 71. This meshing method enables efficient power transmission between the two bevel gears and changes the direction of power transmission at the same time. When the second bevel gear 74 rotates with the rotating shaft 73, through meshing with the first bevel gear 71, the power is transmitted to the first bevel gear 71, thereby driving the excavation assembly 2 to operate. The first gear 77 is fixedly mounted on the rotating shaft 73 and rotates synchronously with the rotating shaft 73. The second gear 78 is rotatably mounted in the housing 5, the second gear 78 is connected to the output end of the motor 6, and the second gear 78 is meshed with the first gear 77. When the motor 6 is started, the output end drives the second gear 78 to rotate. The second gear 78 and the first gear 77 are meshed with each other, transmitting the power of the motor 6 to the first gear 77, thereby driving the rotating shaft 73 to rotate.

[0051] Reference Figure 4 、 Figure 5 and Figure 6, the sieving component 3 includes: a sieve trough 31, a limiting groove 32, a sliding groove 33, a sliding rod 34, and a first sieve hole 35. There are two limiting grooves 32, which are symmetrically installed on both sides of the inner wall of the frame 1 respectively. Both sides of the sieve trough 31 are slidably installed in the two limiting grooves 32 respectively, ensuring that the sieve trough 31 can move smoothly in a straight line under the constraint of the limiting groove 32 and avoiding deviation from the position. The sieve trough 31 is a hollow structure with an open top, ensuring that the poured sediment and wet soil can stably enter it and be supported. There are several first sieve holes 35, which are arranged in an array on the bottom of the sieve trough 31. When the wet soil and sediment enter the sieve trough 31, the smaller particles will fall through the first sieve holes 35, while the larger particles will be intercepted in the sieve trough 31, thus realizing the separation of materials and completing the sieving work. The supporting comb teeth 4 are fixedly connected to the sieve trough 31. There are two sliding grooves 33, which are symmetrically opened on both sides of the frame 1 respectively. There are two sliding rods 34, which are installed on both sides of the sieve trough 31 respectively, and the two sliding rods 34 are respectively slidably installed in the two sliding grooves 33. The sliding grooves 33 can further provide a limiting effect on the sliding rods 34, ensuring that the sieve trough 31 can move stably. In addition, in order to enable the sieve trough 31 to reciprocate along the limiting groove 32 and complete the sieving action, the following solution is proposed: The driving mechanism 7 further includes: a rotating roller 75 and a driving groove 76. The rotating roller 75 is fixedly connected to the end of the rotating shaft 73 away from the second bevel gear 74. When the motor 6 is started, the power is transmitted to the first gear 77 through the second gear 78, and then drives the rotating shaft 73 to rotate. Since the rotating roller 75 is closely connected to the rotating shaft 73, the rotation of the rotating shaft 73 will directly drive the rotating roller 75 to rotate synchronously. The driving groove 76 is opened on the rotating roller 75 in a head-to-tail connection, forming a continuous and circular track. One of the sliding rods 34 extends into the driving groove 76. When the rotating roller 75 rotates, by using the limitation of the driving groove 76 on the sliding rod 34, the sieve trough 31 can reciprocate to perform the sieving work.

[0052] The working principle of the above structure is as follows: Turn on the motor 6, and the output end thereof drives the connected second gear 78 to rotate. Thereby driving the components fixedly installed on the same rotating shaft 73 as the first gear 77 to rotate together. The rotation of the rotating shaft 73 drives the second bevel gear 74 to rotate, thereby driving the first bevel gear 71 to rotate and simultaneously causing the roller 75 to rotate. The first bevel gear 71 is connected to one of the rotating disks 21 in the excavation assembly 2, thereby driving the rotating disk 21 to rotate. Thereby driving the excavating bucket 23 to rotate. During the rotation of the excavating bucket 23, the shovel teeth 26 first cut into the wetland soil, shoveling up the wet soil, sediment, and sundries mixed therein on the surface layer of the wetland. When the excavating bucket 23 rotates to the overturning state, the materials in the excavating bucket 23 are poured onto the supporting comb teeth 4. The large objects pass through the guiding of the supporting comb teeth 4 and fall into the sieve filtering groove 31 of the sieving assembly 3, while the small sediment will fall back to the ground through the gaps between two adjacent strip-shaped teeth, realizing preliminary screening. At the same time, when the roller 75 rotates, the synchronous circular motion of the driving groove 76 can make the sliding rod 34 connected thereto perform a linear motion. Thereby driving the sieve filtering groove 31 to reciprocate along the limiting groove 32 and the sliding groove 33. During the reciprocating movement of the sieve filtering groove 31, the materials entering the sieve filtering groove 31 continuously tumble and move, and the smaller particles fall through the first sieve holes 35, while the larger particles are intercepted in the sieve filtering groove 31, completing fine screening.

[0053] The above structure can accurately realize the wet soil and sediment on the soil surface layer, and can realize the screening of this part of the materials, and can automatically collect the large sundries. At the same time, it can drive the reciprocating movement of the sieving assembly 3 while driving the excavation assembly 2 to turn over and excavate, thereby screening the wet soil and sediment. At the same time, the drainage port 25 in the excavation assembly 2 and the supporting comb teeth 4 are used to realize preliminary screening; and the supporting comb teeth 4 are used to realize the transfer of materials and avoid interference.

[0054] Reference Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9As shown, the excavating and sieving device for wetland soil remediation further includes: a collection tank 8 is installed on the frame 1, and a number of reflux holes 9 are arranged in an array at the bottom of the collection tank 8. The reflux holes 9 can play the role of draining water and liquid. A guide plate 10 is installed on the side of the collection tank 8 opposite to the sieving assembly 3. There are several guide plates 10, which are respectively installed at equal intervals on the side of the collection tank 8 opposite to the sieving assembly 3. The upper surface of the guide plate 10 is inclined upward from the collection tank 8 towards the sieving assembly 3. This can enable the material to slide into the collection tank 8 along the inclined plane under the action of its own weight. A turning mechanism 12 is installed between the collection tank 8 and the sieving assembly 3. The turning mechanism 12 is used to transfer the large debris in the sieving assembly 3 into the collection tank 8 for collection. A number of avoidance grooves 11 are provided on the side of the sieve filter tank 31 opposite to the guide plate 10, and the number of avoidance grooves 11 is arranged staggered with the number of guide plates 10. When the turning mechanism 12 starts to work, interference can be avoided to ensure the smooth progress of the turning process. At the same time, the avoidance grooves 11 also provide space for subsequent turning actions, enabling the turning strips 122a to better penetrate into the sieve filter tank 31 to fully turn and transfer the material. The turning mechanism 12 includes: a rotating member 121, a turning plate 122, turning strips 122a, a third gear 123, a connecting frame 124, an electric push rod 125, a driving block 126, and a rack 127. There are two rotating members 121, which are respectively rotatably installed on the sieve filter tank 31 symmetrically to each other. The turning plate 122 is installed between the two rotating members 121, and the two form an integral body to ensure that the turning plate 122 can rotate with the rotation of the rotating member 121. A number of turning strips 122a are installed on the turning plate 122 at equal intervals, and the number of turning strips 122a are respectively located in the number of avoidance grooves 11. In the initial state, the turning strips 122a are in contact with the bottom of the sieve filter tank 31, which can support the remaining large debris after screening, and the turning strips 122a do not block the first sieve holes 35. When the rotating member 121 drives the turning plate 122 to rotate, it can turn and push the large debris in the sieve filter tank 31. During this process, the turning strips 122a will move up and down smoothly in the avoidance grooves 11 to avoid interference. The third gear 123 is rotatably installed on the sieve filter tank 31 and is connected to one of the rotating members 121. Its function is to transmit power to the rotating member 121 to drive the turning plate 122 to rotate. When the third gear 123 rotates, it will directly drive the connected rotating member 121 to rotate, thereby realizing the turning action of the turning plate 122. The connecting frame 124 is installed on the sieve filter tank 31; the electric push rod 125 is installed on the connecting frame 124. The driving block 126 is installed at the output end of the electric push rod 125 and moves with the telescopic movement of the electric push rod 125. The rack 127 is installed on the driving block 126, and the rack 127 is meshed with the third gear 123.When the electric push rod 125 expands and contracts, it will drive the driving block 126 and the rack 127 to move together. The linear motion of the rack 127 will be converted into the rotation of the third gear 123, thereby driving the rotating member 121 and the turning plate 122 to rotate, realizing the turning and transfer of large debris in the sieve filter tank 31.

[0055] The specific usage method of the above structure is as follows: When it is necessary to transfer the large debris in the sieve filter tank 31 to the collection tank 8, start the electric push rod 125. The output end of the electric push rod 125 extends, driving the driving block 126 and the rack 127 to perform linear motion. The motion of the rack 127 causes the third gear 123 meshing with it to rotate. The third gear 123 drives the rotating member 121 connected to it to rotate. The rotation of the rotating member 121 causes the turning plate 122 and the turning strip 122a installed on it to rotate accordingly, turning up the large debris in the sieve filter tank 31 and pushing it into the collection tank 8 along the guiding direction of the guiding plate 10 ( Figure 10 which is a schematic diagram of the turning state), completing the transfer and collection process of the debris. This structure can collect the remaining large debris after filtration, which is convenient for use.

[0056] In addition, this wetland soil remediation excavating and sieving device further includes: crawler wheels 13, counterweight blocks 14, and a push rod 15. There are two crawler wheels 13, which are respectively installed on both sides of the frame 1. The crawler wheels 13 are existing devices. In the special terrain environment of wetlands, which is soft, muddy, and has poor bearing capacity, the crawler wheels 13 can evenly disperse the weight of the device, greatly reducing the pressure borne by the ground per unit area. This effectively prevents the device from sinking into the wetland mud and ensures that the device moves smoothly and smoothly on the wetland surface, providing a stable support platform for excavation and screening operations. The counterweight block 14 is installed on the side of the frame 1 away from the excavation assembly 2. The counterweight block 14 is used to balance the center of the device and prevent the device from tipping over. The push rod 15 is installed on the frame 1, facilitating the staff to push the device to the designated position.

[0057] The above specific implementation manners do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
