DETAILED DESCRIPTION

[0039] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0040] Please refer to Figures 1-10 The present application provides a technical solution: a dredger anchor throwing device, comprising a frame body 34 and a shell 4, a winding wheel 1 is rotatably arranged on one side of the upper end of the frame body 34, an anchor chain 3 is wound on the winding wheel 1, an anchor head 5 is arranged at the end of the anchor chain 3, the anchor chain 3 passes through the through holes on the upper and lower sides of the shell 4, a mounting plate 17 is arranged on one side of the shell 4, and a hooking assembly for removing aquatic plants wound on the anchor chain 3 is further arranged on the shell 4.

[0041] The hooking assembly comprises a plurality of support rods 18 fixedly connected to the inner wall of the shell 4, a rotating plate 20 rotatably arranged on one side of the lower end of the support rod 18, and an elastic claw 21 fixedly connected to one end of the rotating plate 20.

[0042] The upper and lower sides of the shell 4 are further provided with a limiting assembly for keeping the anchor chain 3 stable in the shell 4.

[0043] The limiting assembly comprises a plurality of sliding blocks 27 rotatably arranged on one side of the shell 4.

[0044] In this embodiment, as Figure 2、 Figure 4 、 Figure 5 As shown in FIG. 1, the upper end of the frame body 34 is fixedly connected with a motor 2, and the output end of the motor 2 is fixedly connected with the winding wheel 1.

[0045] The lower end of the support rod 18 is fixedly connected with a motor 19, and the output end of the motor 19 is fixedly connected with one end of the rotating plate 20.

[0046] Specifically, the existing anchor device is used to release the anchor chain 3 by the winding wheel 1 when in use, so that the anchor chain 3 enters the water. However, aquatic plants such as waterweeds and reeds in the water can easily float with the water flow and entangle on the surface of the anchor chain 3. When the anchor chain 3 is wound, the anchor chain 3 will carry these aquatic plants to the winding wheel 1, thereby increasing the friction between the anchor chain 3 and the winding wheel 1, resulting in increased resistance during unwinding, decreased smoothness, and affecting subsequent use.

[0047] Therefore, in order to solve the above problems, the frame body 34 and the mounting plate 17 are installed on the dredger in use, and the anchor chain 3 always passes through the through holes on the upper and lower sides of the shell 4. When the dredger needs to be docked for operation, the motor 2 is used to drive the winding wheel 1 to rotate, and the winding wheel 1 releases the wound anchor chain 3 until the anchor head 5 sinks to the bottom of the water, so that the dredger can be kept stable.

[0048] When the operation is completed, the winding wheel 1 is driven to rotate again, and the anchor chain 3 is wound. During the winding process of the anchor chain, the plurality of motors 19 are started at the same time, the motors 19 drive the rotating plate 20 to rotate, and the elastic claws 21 at the end of the rotating plate 20 will contact the anchor chain 3. Since the elastic claws 21 and the rotating plate 20 have an included angle, the elastic claws 21 can hook the aquatic plants entangled on the anchor chain 3. The elastic claws 21 are made of flexible material and will not interfere with the movement of the anchor chain 3, and the elastic claws 21 are not easy to be damaged. Therefore, under the cooperation of the plurality of elastic claws 21 and the rotating plate 20, the aquatic plants entangled on the anchor chain 3 are hooked off, thereby avoiding the situation that the aquatic plants entangled on the surface of the anchor chain 3, the anchor chain 3 carries these aquatic plants to the winding wheel 1 when the anchor chain 3 is wound, thereby increasing the friction between the anchor chain 3 and the winding wheel 1, resulting in increased resistance during unwinding, decreased smoothness, and affecting subsequent use.

[0049] In the embodiment, as shown in FIG. 1, the rotating plate 20 is further provided with a self-cleaning assembly. Figure 5

[0050] The self-cleaning assembly comprises a cylinder 23 fixedly connected to one side of the rotating plate 20, and a scraper 22 fixedly connected to the piston end of the cylinder 23. The scraper 22 is sleeved on the rotating plate 20 and slidably connected thereto.

[0051] ​Specifically, in the above embodiment, although the aquatic plants wrapped on the surface of the anchor chain 3 can be scraped off by the elastic claws 21, after the elastic claws 21 hook the aquatic plants, the aquatic plants can cover the elastic claws 21 or the rotating plate 20, so that the elastic claws 21 and the rotating plate 20 can be difficult to scrape the aquatic plants again, which affects the subsequent use. Therefore, in order to avoid this problem, when the rotating plate 20 and the elastic claws 21 complete a scraping action and move away from the anchor chain 3, the cylinder two 23 drives the scraper 22 to move along the surface of the rotating plate 20 to form scraping with the surface of the rotating plate 20. At the same time, since the elastic claws 21 are elastic, the elastic claws 21 will also be flattened under the action of the scraper 22 until the scraper 22 reaches the end position of the elastic claws 21. Then the aquatic plants covered on the elastic claws 21 or the rotating plate 20 are scraped off, and then the scraper 22 is reset, the elastic claws 21 are restored, and then the above operation is repeatedly performed, so that the surface of the elastic claws 21 and the scraper 22 can be cleaned in real time, avoiding the situation that after the elastic claws 21 hook the aquatic plants, the aquatic plants cover the elastic claws 21 or the rotating plate 20, so that the elastic claws 21 and the rotating plate 20 are difficult to hook the aquatic plants wrapped on the anchor chain 3, thereby affecting the subsequent use.

[0052] In this embodiment, as shown in Figure 2 、 Figure 7 、 Figure 8 One end of the sliding block 27 is rotatably provided with a connecting rod 26, one end of the connecting rod 26 is rotatably provided with a rotating ring 6, the rotating ring 6 is rotatably provided with a fixed ring 7, one side of the fixed ring 7 is fixedly connected to the shell 4.

[0053] One side of the rotating ring 6 is fixedly connected with a sliding groove rod 30, the sliding groove rod 30 is inserted and slidably connected with a guide column 31 at the sliding groove, one end of the guide column 31 is fixedly connected with a displacement block 32, the displacement block 32 is slidably connected to the shell 4, one side of the displacement block 32 is fixedly connected with a spring 29, the other end of the spring 29 is fixedly connected to the shell 4, the right side of the upper and lower end faces of the shell 4 is rotatably provided with a push rod 33, the upper and lower sides of the inner cavity of the shell 4 are fixedly connected with a motor four 24, and one end of the push rod 33 is fixedly connected with the output end of the motor four 24.

[0054] Specifically, since the dredger is operating in the water area, and the wind force around the water area is usually large, when the anchor chain 3 is reeled in, it is easy to swing due to the wind force, so that the elastic claw 21 is not easy to fit the surface of the anchor chain 3. Therefore, in order to avoid this situation, when the water plants wrapped on the surface of the anchor chain 3 are removed, it is carried out in the shell 4. The shell 4 can partially prevent the wind on the anchor chain 3, and ensure the smooth operation of the hooking work. Since the upper side of the shell 4 is provided with a through hole, when the anchor chain 3 passes through the through hole, due to the particularity of the shape of the anchor chain 3, the anchor chain 3 is easy to be hooked at the through hole of the shell 4 when the anchor chain 3 contacts with the hole wall of the through hole of the shell 4, so that the anchor chain 3 is stuck in the reeling process, affecting the normal reeling of the anchor chain 3. Therefore, in order to avoid this problem, when the anchor chain 3 is reeled in, the two ends of the part of the anchor chain 3 in the shell 4 are in contact with the limiting ball 28, and under the transmission of the sliding block 27, the connecting rod 26 and the rotating ring 6, the plurality of limiting balls 28 will be in contact with the surface of the anchor chain 3 under the action of the spring 29, so that the anchor chain 3 is in the central position of the through hole of the shell 4, so that the shell 4 can be used to avoid the anchor chain 3 being blown by the wind, and the anchor chain 3 can be prevented from being stuck in the through hole on the upper and lower sides of the shell 4, so as to ensure the normal reeling of the anchor chain 3. In order to avoid that the drawings of the specification are not easy to observe, the limiting assembly is only displayed in the drawings, and is above the shell 4;

[0055] When the anchor chain 3 is unwound, the push rod 33 can be driven to rotate by the motor four 24, so that the push rod 33 is in contact with the displacement block 32, the displacement block 32 slides, the limiting ball 28 is away from the anchor chain 3, so as to reduce the friction between the limiting ball 28 and the anchor chain 3, which is beneficial to prolong the service life of the limiting ball 28 and the anchor chain 3.

[0056] In the embodiment, as shown in Figures 2-4 , Figure 6 , Figure 10 , the inner cavity of the shell 4 is also provided with an aggregation assembly;

[0057] The aggregation assembly is fixedly connected to the surrounding plate 11 at the bottom of the inner cavity wall of the shell 4. The aggregation plate 8 is inserted and slidably connected to the two sides of the surrounding plate 11. The surrounding block 12 is slidably connected to the two sides of the lower end surface of the inner cavity wall of the shell 4. The air cylinder one 16 is fixedly connected to the upper end surface of the surrounding block 12. The piston end of the air cylinder one 16 is fixedly connected to one end of the aggregation plate 8.

[0058] The gear ring 13 is fixedly connected to the middle of the lower end surface of the inner cavity of the shell 4. The gear wheel 14 is rotatably arranged on one side of the surrounding block 12. The gear wheel 14 and the outer ring tooth block of the gear ring 13 are mutually engaged. The motor two 15 is fixedly connected to one side of the lower end surface of the inner cavity of the shell 4. The output end of the motor two 15 is fixedly connected to the gear wheel 14.

[0059] The discharge port 9 is arranged on one side of the bottom of the shell 4. The baffle 10 is rotatably arranged on one side of the lower end surface of the shell 4. The baffle 10 covers the discharge port 9 when it rotates.

[0060] The lower end surface of the shell 4 is fixedly connected with a motor 25, and the output end of the motor 25 is fixedly connected with one end of the baffle 10.

[0061] Specifically, in the above embodiment, although the shell 4 can be used to prevent the chain 3 from swinging and affecting the scraping effect of the elastic claw 21, the aquatic plants falling through the elastic claw 21 will also be in the inner cavity of the shell 4, so that the aquatic plants accumulate in the shell 4, and the elastic claw 21 may again contact the aquatic plants that have been scraped off, thereby affecting the subsequent scraping effect of the elastic claw 21. Therefore, in order to avoid this situation, in the use of the present embodiment, the two accumulation plates 8 in the initial state are on the same side and close to each other, and the bottom of the accumulation plate 8 is attached to the bottom of the inner cavity wall of the shell 4. When the elastic claw 21 works, the two motors 15 drive the two gears 14 to rotate in different directions at the same time, so that the two ring blocks 12 slide at the bottom of the inner cavity of the shell 4 and make circular motion, and the accumulation plate 8 moves to the other side of the inner cavity of the shell 4. During the movement of the accumulation plate 8, the aquatic plants at the bottom of the inner cavity of the shell 4 are pushed. Since the two accumulation plates 8 are first away from each other and then close to each other, the aquatic plants are gathered at the discharge port 9, and the volume of the aquatic plants is reduced. At this time, the motor 25 drives the baffle 10 to rotate, and the aquatic plants fall out of the discharge port 9, and then the baffle 10 is closed, and the cylinder 16 drives the accumulation plate 8 to rise, and the accumulation plate 8 is reset. The accumulation plate 8 is first raised and then reset, which can avoid pushing the subsequent aquatic plants falling into the inner cavity of the shell 4 back when the accumulation plate 8 is reset, and then repeating the above operation, so that the aquatic plants at the bottom of the inner cavity of the shell 4 can be removed in real time, thereby avoiding the situation that the elastic claw 21 again contacts the aquatic plants that have been scraped off, affecting the subsequent scraping effect of the elastic claw 21 on the aquatic plants winding on the surface of the chain 3. In addition, since the aquatic plants in the shell 4 are first gathered and then discharged, the discharge range of the aquatic plants is small, and the area of the discharge port 9 is also small, thereby avoiding the situation that the shell 4 is filled with air when the aquatic plants are discharged from the shell 4 due to the large size of the discharge port 9, and the part of the chain 3 in the shell 4 swings and affects the normal work of the elastic claw 21.

[0062] Working principle: the frame 34 and the mounting plate 17 are installed on the dredger, and the anchor chain 3 always passes through the through hole on the upper and lower sides of the shell 4, when the dredger needs to be docked for work, the motor 2 drives the winding wheel 1 to rotate, the winding wheel 1 unwinds the winding anchor chain 3 until the anchor head 5 sinks into the bottom of the water, so that the dredger can be kept stable, when the work is finished, the winding wheel 1 is driven to rotate again, and the anchor chain 3 is wound, during the winding process of the anchor chain, multiple motors three 19 are started at the same time, the motor three 19 drives the rotating plate 20 to rotate, when the rotating plate 20 rotates, the elastic claw 21 at the end of the rotating plate 20 will contact with the anchor chain 3, because the elastic claw 21 and the rotating plate 20 have an angle, so the elastic claw 21 will have the effect of picking up the aquatic plants winding on the anchor chain 3, and the elastic claw 21 is flexible material, which will not interfere with the movement of the anchor chain 3, and the elastic claw 21 is not easy to damage, so that under the cooperation of multiple elastic claws 21 and rotating plates 20, the aquatic plants winding on the anchor chain 3 are hooked off, avoiding the situation that the aquatic plants winding on the surface of the anchor chain 3, when the anchor chain 3 is wound, the anchor chain 3 carries these aquatic plants to the winding wheel 1, thereby increasing the friction between the anchor chain 3 and the winding wheel 1, resulting in increased resistance during unwinding, decreased smoothness, and affecting subsequent use.When the rotating plate 20 and the elastic claw 21 complete a scraping action and move away from the anchor chain 3, the cylinder two 23 drives the scraper 22 to move along the surface of the rotating plate 20, and the scraper 22 is scraped with the surface of the rotating plate 20. At the same time, since the elastic claw 21 has elasticity, the elastic claw 21 is also flattened under the action of the scraper 22 until the scraper 22 reaches the end position of the elastic claw 21. Then the aquatic plants covered on the elastic claw 21 or the rotating plate 20 are scraped off, and then the scraper 22 is reset, the elastic claw 21 is restored, and then the above operation is repeatedly performed, that is, the surface of the elastic claw 21 and the scraper 22 can be cleaned in real time, which avoids the situation that after the elastic claw 21 hooks the aquatic plants, the aquatic plants cover the elastic claw 21 or the rotating plate 20, so that the elastic claw 21 and the rotating plate 20 cannot hook the aquatic plants wound on the anchor chain 3, thereby affecting the subsequent use. When the aquatic plants wound on the surface of the anchor chain 3 are removed, it is carried out in the shell 4. The shell 4 can partially prevent the wind of the anchor chain 3, so as to ensure the smooth progress of the hooking work. Since the upper side of the shell 4 is provided with a through hole, when the anchor chain 3 passes through the through hole, due to the particularity of the shape of the anchor chain 3, the anchor chain 3 is easily hooked at the through hole of the shell 4 when the anchor chain 3 contacts the hole wall of the through hole of the shell 4, thereby causing the anchor chain 3 to be stuck during the winding process, affecting the normal winding of the anchor chain 3. Therefore, in order to avoid this problem, when the anchor chain 3 is wound, the two ends of the part of the anchor chain 3 in the shell 4 are in contact with the limiting balls 28, and under the transmission of the sliding block 27, the connecting rod 26 and the rotating ring 6, the plurality of limiting balls 28 are in contact with the surface of the anchor chain 3 under the action of the spring 29, so that the anchor chain 3 is in the central position of the through hole of the shell 4. Therefore, the shell 4 can be used to avoid the anchor chain 3 from being blown by the wind, and the anchor chain 3 can also be prevented from being stuck in the through holes on the upper and lower sides of the shell 4, so as to ensure the normal winding of the anchor chain 3. When the anchor chain 3 is unwound, the push rod 33 is driven to rotate by the motor four 24, so that the push rod 33 is in contact with the displacement block 32, the displacement block 32 slides, and the limiting ball 28 moves away from the anchor chain 3, thereby reducing the friction between the limiting ball 28 and the anchor chain 3, which is beneficial to prolong the service life of the limiting ball 28 and the anchor chain 3.The two gathering plates 8 in the initial state are on the same side and close to each other, and the bottom of the gathering plate 8 is attached to the bottom of the inner cavity wall of the shell 4. When the elastic claw 21 works, the two motors two 15 drive the two gears 14 to rotate in different directions at the same time, so that the two surrounding blocks 12 slide at the bottom of the inner cavity of the shell 4 and make circular motion, so that the gathering plate 8 moves to the other side of the inner cavity of the shell 4. During the movement of the gathering plate 8, the aquatic plants at the bottom of the inner cavity of the shell 4 are pushed. Since the two gathering plates 8 are first away and then close, the aquatic plants will converge at the discharge port 9, and the volume of the aquatic plants is reduced. At this time, the baffle 10 is driven to rotate by the motor five 25, and the aquatic plants fall out of the discharge port 9, and then the baffle 10 is closed, the gathering plate 8 is driven upward by the cylinder one 16, and the gathering plate 8 is reset. The gathering plate 8 is first raised and then reset, which can avoid pushing back the aquatic plants that fall into the bottom of the inner cavity of the shell 4 when the gathering plate 8 is reset, and then the above operation is repeated, so that the aquatic plants at the bottom of the inner cavity of the shell 4 can be removed in real time, avoiding the situation that the elastic claw 21 contacts the aquatic plants that have been scraped off again, affecting the scraping effect of the elastic claw 21 on the aquatic plants wrapped on the surface of the anchor chain 3. Since the aquatic plants in the shell 4 are first converged and then discharged, the discharge range of the aquatic plants is also small, so the area of the discharge port 9 is also small, thereby avoiding the situation that the anchor chain 3 in the shell 4 is swung and affects the normal work of the elastic claw 21 when the aquatic plants are discharged from the shell 4 due to the large size of the discharge port 9.
