Description

Technical Field

[0001] The invention relates to the technical field of pond dredging, in particular to a device for dredging bottom mud in an aquaculture pond. Background Art

[0002] Dredging of saline-alkali pond bottom mud is an important means to maintain the pond ecological environment and aquaculture conditions. The cleared bottom mud contains rich organic matter and nutrients such as nitrogen and phosphorus. Therefore, dredging equipment is used to clean the sludge in the aquaculture pond. The extracted sludge can be used as farmland fertilizer or landscaping matrix after proper treatment, realizing the recycling of resources.

[0003] In the prior art, when cleaning the silt in saline-alkali ponds, suction or mechanical methods are usually used for dredging. However, the suction dredging device relies on a water pump to generate negative pressure for dredging. Since the suction port is in point contact with the bottom of the pond, the dredging coverage is limited and it is difficult to completely remove the silt on the irregular bottom of the pond. The mechanical dredging device uses a scraper to directly remove the silt. Although this method improves the dredging efficiency, the scraper structure is rigid and cannot adapt to the fluctuations of the pond bottom, resulting in low dredging efficiency and increased operating costs.

The heavy bottom mud particles gradually settle to the bottom and are discharged through the bottom of the discharge hood. The silt is extracted by means of an extraction machine for reuse, and the upper clear water is discharged from the diversion hole to achieve mud and water separation. The mud and water separation is completed by the principle of gravity sedimentation. The design of the dividing inclined plate increases the sedimentation area, improves the separation efficiency, and brings greater convenience and benefits to the dredging operation.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Please refer to Figures 1 to 10 :

[0039] Example 1:

[0040] The present invention provides a device for desilting bottom mud in an aquaculture pond. The device comprises a mobile support 1 having an I-shaped frame structure. A servo motor 4 is mounted on the inside of the mobile support 1. A gear is mounted on the output end of the servo motor 4. A protective cover 101 is mounted on the top edge of the mobile support 1. Limit plates 102 are mounted on the rear ends of both sides of the mobile support 1. An adjustment support plate 103 is slidably mounted between the limit plates 102 and the inner sidewall of the mobile support 1. The inner top of the adjustment support plate 103 is connected to the top of the limit plate 102 via a spring. A waterproof motor 5 is mounted on the outside of the bottom of the adjustment support plate 103. A wheel 104 is mounted on the output end of the waterproof motor 5. The wheel 104 is located on the inner side of the bottom of the adjustment support plate 103. A driving shaft 106 is rotatably mounted on the inside of the mobile support 1. A gear is mounted on the driving shaft 106 as a driven wheel. The driven wheel on the driving shaft 106 meshes with the gear connected to the output end of the servo motor 4.

[0041] In the disclosed embodiment, when silting the bottom of the aquaculture pond, limit plates 102 are installed on both side ends of the rear of the mobile bracket 1. The support plate 103 is adjusted to move between the side ends of the limit plate 102 and the side ends of the mobile bracket 1 according to the undulation of the pond bottom to adapt to the different undulating conditions of the pond bottom terrain. The waterproof motor 5 provided on the outside of the bottom of the adjustment support plate 103 drives the wheels 104 to rotate, which can drive the mobile bracket 1 to move on the bottom of the pond. The waterproof motor 5 is a DC reduction motor. The waterproof motor 5 provides the driving force for movement, and the waterproof motors 5 located at the two rear locations respectively drive the corresponding wheels 104 to rotate at different speeds to achieve the adjustment of the forward or backward position of the entire device. The protective cover 101 prevents the influence of debris such as water plants on the mobile bracket 1.

[0042] Example 2:

[0043] Based on the first embodiment, support plates 2 are installed in the frames of both side ends of the mobile bracket 1. A drive motor 6 is installed inside one side end of the mobile bracket 1. Guide rails 201 are installed on the inner ends of the two support plates 2. Sliding plates 202 are slidably installed on the brackets of the two guide rails 201. The bottoms of the two ends of the sliding plates 202 are connected to the upper end surface of the mobile bracket 1 through springs. Guide rollers 203 are rotatably installed on the front and rear positions of both ends of the sliding plates 202, and rotating rods 204 are rotatably installed on the tops of the two support plates 2. A transmission rod 205 is rotatably installed on the inner side of the mobile bracket 1. The transmission rod 205 is a cylindrical structure, and the end of the transmission rod 205 close to the inner side is connected to a rotating cam 206. The rotating cam 206 has a cylindrical body and three different contour curves are machined on the outer circumference, among which the base circle segment is a circular arc surface, the lifting segment is an involute surface, and the rotating segment is a cycloid surface. The outer end of the transmission rod 205 is connected to the end of the rotating rod 204 via a pulley, and the end of the transmission rod 205 closest to the outside is connected to the output end of the drive motor 6. A swing arm 207 is hingedly mounted in the middle of the bottom of the sliding plate 202, and the bottom of the swing arm 207 is connected to the mounting frame 208; the bottom of the mounting frame 208 is provided with a slot, and a scraper 209 is slidably mounted inside the slot. The side of the mounting frame 208 is installed with fixing bolts, and the inner ends of the fixing bolts are mounted on the side of the scraper 209. The three scrapers 209 are fixed to the mounting frame 208 by fixing bolts to facilitate later disassembly and replacement.

[0044] A dividing plate 2010 is installed on the driving shaft 106, and guide grooves 2011 are symmetrically opened on the end faces of both sides of the dividing plate 2010. Each guide groove 2011 is composed of three sections of grooves, among which the first section of the groove is arc-shaped, the second section of the groove is involute-shaped, and the third section of the groove is cycloid-shaped; the guide groove 2011 is slidably connected to a guide member 2012, one end of the guide member 2012 is located in the guide groove 2011 and can slide along the guide groove 2011, and both ends of the mounting frame 208 are connected to a positioning member 2013, and one end of the positioning member 2013 is connected to the other end of the guide member 2012 through a spring.

[0045] When desilting the bottom of the aquaculture pond, the drive motor 6 located in the side end of the mobile support 1 is started and drives the transmission rod 205 to rotate. The transmission rod 205 drives the rotating rod 204 to rotate relative to the support plate 2 via a pulley. The other end of the rotating rod 204 drives the transmission rod 205 at the other end of the mobile support 1 via a pulley. The transmission rods 205 at both ends respectively drive the rotating cam 206 at the corresponding end to rotate. Due to the force of the spring, the sliding plate 202 drives the guide roller 203 to always fit with the outer edge of the rotating cam 206. The rotating cam 206 rotates and pushes the guide roller 203 to drive the sliding plate 202 to move. The two ends of the sliding plate 202 move in the vertical direction along the guide rail 201 located on the inner side of the support plate 2. The bottom of the sliding plate 202 drives the mounting frame 208 to move via the swing arm 207. The bottom of the mounting frame 208 is equipped with three scrapers 209. When the rotating cam 206 rotates to the base circle section, the sliding plate 202 remains in the lowest position and the scraper 209 is close to the bottom of the pool; when the rotating cam 206 rotates to the lifting section, the sliding plate 202 moves upward under the action of the contour of the rotating cam 206, driving the swing arm 207 to lift, causing the scraper 209 to swing and clear the mud in the dead corner; when the rotating cam 206 rotates to the rotation section, the sliding plate 202 slowly descends under the action of gravity and the tension of the spring, causing the scraper 209 to return to the working position smoothly. When the movable bracket 1 moves, it drives the scraper 209 to scrape and clean the sludge on the pool bottom. Simultaneously, the driving shaft 106 rotates the indexing plate 2010, causing the guide member 2012 to move within the guide groove 2011. Because the shape of the guide groove 2011 corresponds to that of the rotating cam 206, with the first segment of the groove being an arc, the second segment being an involute, and the third segment being a cycloid, the guide groove 2011 can coordinate with the rotating cam 206 when cleaning sludge, utilizing the same segments to control the movement of the scraper 209. When the indexing plate 2010 rotates, the guide member 2012 and the spring disposed between the guide member 2012 and the positioning member 2013 drive the positioning member 2013 to move, thereby causing the mounting frame 208 to swing. Simultaneously, the spring allows the scraper 209 to swing in close contact with the pool bottom to clean the sludge. This arrangement allows the position of the scraper 209 to be adjusted to adapt to the undulations of the pool bottom.

[0046] In summary, the scraper 209 moves in the vertical direction under the push of the rotating cam 206, and at the same time, the positioning part 2013 is driven by the dividing plate 2010 to pull the mounting frame 208 to make the scraper 209 swing. The scraper 209 can automatically adjust the movement trajectory according to the shape of the pool bottom, and can achieve dredging of irregular pool bottoms, thereby improving cleaning efficiency.

[0047] Example 3, based on Example 1, refer to Figure 8 and Figure 9A collection box 3 is installed on the rear side of the mobile bracket 1. A sedimentation box 301 is installed at the bottom of the collection box 3. A discharge cover 302 is installed at the bottom of the sedimentation box 301. The discharge cover 302 is a conical structure, and a guide hole 303 is opened on the top of the outer side of the discharge cover 302. A plurality of equally spaced partition slant plates 304 are installed on the inner side of the sedimentation box 301. One end of each partition slant plate 304 is fixed to the inner wall of the sedimentation box 301. The partition slant plates 304 gradually tilt downward from the bottom to the top. The partition slant plates 304 at the bottom are arranged parallel to the slope of the pool bottom, and the partition slant plates 304 at the top gradually increase in inclination to form a gradient sedimentation space. Slide rails 305 are mounted on both the upper and lower end surfaces of the collection box 3. A guide rod 306 is slidably mounted between the upper and lower slide rails 305. The upper and lower ends of the guide rods 306 are slidably connected to the upper and lower slide rails 305, respectively. For example, two guide rods 306 are mounted on each end. Guide plates 307 are slidably mounted on the guide rods 306. Each guide rod 306 extends through the guide plates 307. Deflectors 308 are hingedly connected to the outer edges of the guide plates 307. The bottom of the deflector plates 308 is located below the scraper 209. Connecting plates 309 are mounted on both ends of the bottom of the deflector plates 308. The other ends of the connecting plates 309 are rotatably connected to the outer end surfaces of the scraper 209.

[0048] When the scraper 209 is moving to desilt the bottom of the aquaculture pond, it drives the guide plate 308 through the connecting plate 309. The guide plate 308 rotates around the connection with the outer end of the guide plate 307, simultaneously driving the guide plate 307 to move up and down along the guide vertical rod 306. The guide plate 307 also drives the ends of the guide vertical rod 306 to move horizontally along the slide rail 305. The sludge removed by the scraper 209 flows through the guide plate 308 to the guide plate 307 and enters the interior of the collection box 3. After entering the sedimentation tank 301 of the collection box 3, the sludge gradually settles along the dividing inclined plates 304 under the action of gravity. The heavy bottom mud particles gradually settle to the bottom of the discharge cover 302. The upper layer of clear water after sedimentation is discharged from the guide hole 303, achieving mud and water separation. The bottom of the discharge cover 302 is connected to an extraction device, which can extract the settled sludge for reuse.

[0049] Example 4, based on Example 1, refer to Figure 10The front ends of both ends of the mobile bracket 1 are rotatably mounted with rotating vertical rods 7. The rotating vertical rods 7 are cylindrical in structure, and a rotating support plate 701 is mounted at the bottom of the rotating vertical rod 7. A steering wheel 702 is rotatably mounted at the bottom of the rotating support plate 701. A connecting crossbar 703 is fixedly mounted on the outside of the rotating vertical rod 7. A steering crossbar 704 is rotatably mounted on the side ends of the connecting crossbar 703. Guide blocks 705 are protrudingly mounted on the upper and lower end surfaces of the steering crossbar 704 at the middle position. A steering motor 706 is mounted at the middle position of the front side of the mobile bracket 1. A steering plate 707 is mounted on the output end of the steering motor 706 at the bottom. The steering plate 707 has a slot. The guide block 705 is located in the slot of the steering plate 707 and is slidably connected to the slot. When dredging the bottom of the aquaculture pond, the steering motor 706 in the middle position of the front side of the mobile bracket 1 drives the steering plate 707 at the bottom to move. When the steering plate 707 moves, the guide block 705 moves in the slot on its top, so that the guide block 705 drives the steering crossbar 704 to move, and the two ends of the steering crossbar 704 drive the connecting crossbar 703 to move, so that the connecting crossbar 703 drives the rotating vertical rod 7 to move, and then the rotating support plate 701 at the bottom of the rotating vertical rod 7 drives the steering wheel 702 to move, and the steering wheel 702 drives the mobile bracket 1 to steer, which is convenient for steering and moving at the bottom of the pond, and can move and steer quickly and accurately at the bottom of the pond, thereby greatly improving the efficiency of the dredging operation.

[0050] The working principle of this embodiment is as follows:

[0051] When in use, the adjustment support plate 103 can slide between the limit plate 102 and the inner end face of the mobile bracket 1 to adapt to the undulations of the pond bottom. The waterproof motor 5 drives the wheel 104 to rotate and drives the mobile bracket 1 to move at the bottom of the pond. The steering motor 706 drives the steering plate 707 at the bottom to drive the guide block 705 to move. The guide block 705 drives the connecting cross bars 703 at both ends of the steering cross bar 704 to move. The connecting cross bar 703 drives the rotating vertical rod 7 to move. The rotating support plate 701 at the bottom of the rotating vertical rod 7 drives the steering wheel 702 to move, and the steering wheel 702 drives the mobile bracket 1 to steer. The scraper 209 can adjust its position according to the undulations of the pool bottom. The drive motor 6 rotates the transmission rod 205 connected to it at one end, and drives the rotating rod 204 through a belt drive, which in turn drives the transmission rod 205 at the other end. The transmission rods 205 at both ends respectively drive the rotating cams 206 at the corresponding ends to rotate. The rotating cams 206 at both ends respectively drive the guide rollers 203 at the corresponding ends to move, thereby driving the sliding plate 202 to move along the guide rail 201 inside the support plate 2. The sliding plate 202 drives the three scrapers 209 to move via the swing arm 207 and the mounting frame 208. At the same time, the driving shaft 106 rotates the indexing plate 2010, and one end of the guide member 2012 is located in the guide groove 2011 and is slidably connected to the guide groove 2011. The other end of the guide member 2012 drives the positioning member 2013 and the mounting frame 208 to swing through a spring, allowing the scraper 209 to swing along the bottom of the pool to clean the sludge. This allows the mobile bracket 1 to move and drive the scraper 209 to scrape and clean the sludge, removing mud from dead corners. When the scraper 209 moves, it drives the guide plate 308 to move through the connecting plate 309. The sludge removed by the scraper 209 flows through the guide plate 308 to the guide plate 307 and then into the collection box 3. After entering the sedimentation box 301, the sludge settles step by step along the dividing inclined plates 304 from top to bottom under the action of gravity. The heavy bottom mud particles gradually settle to the discharge cover 302 at the bottom. The upper layer of clear water after sedimentation is discharged from the guide hole 303, achieving mud and water separation. The bottom of the discharge cover 302 is connected to an extraction device that can extract the settled sludge for reuse.
