[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figure 1 and Figure 3 A sludge treatment device for water area treatment includes a base 1 and a support frame 27, and the support frame 27 is installed above the base 1. A conveyor belt 3 for conveying a sludge mold is provided on the base 1, and an extrusion head 2 for extruding sludge, a first clamp 9, a second clamp 10, a third clamp 11, and a fourth clamp 12 for clamping the mold are installed on the support frame 27. The extrusion head 2, the first clamp 9, the second clamp 10, the third clamp 11, and the fourth clamp 12 are arranged in sequence on the conveying path of the conveyor belt 3.

[0022] Reference Figure 2 and Figure 4 In the above, the conveyor belt 3 is a closed belt body. Two conveyor wheels 34 and a first motor for driving the conveyor wheels 34 to rotate are provided on the base 1. The two conveyor wheels 34 are used to support the conveyor belt 3, and the first motor realizes the conveyance of the conveyor belt 3 by driving the conveyor wheels 34 to rotate. In this embodiment, the conveying path of the conveyor belt 3 is on the same horizontal plane, and the axis of the conveyor wheel 34 is vertically arranged.

[0023] Further, a plurality of supporting seats 31 are arranged on the conveyor belt 3, and the supporting seats 31 are evenly arranged on the conveying path of the conveyor belt 3. A supporting platform 19 is arranged on the base 1, and the plurality of supporting seats 31 are located on the supporting platform 19. The supporting platform 19 supports the supporting seats 31, and the supporting seats 31 are slidably connected to the supporting platform 19. A feeding plate 33 is arranged on the supporting seat 31. The feeding plate 33 is used for installing the silt mold. The feeding plate 33 realizes the movement of the silt mold through the transmission of the conveyor belt 3. The silt mold sequentially passes through the extrusion head 2, the first fixture 9, the second fixture 10, the third fixture 11, and the fourth fixture 12 through the movement.

[0024] The feeding plate 33 is connected to the supporting seat 31 through a telescopic guide rod 32. The telescopic guide rod 32 is composed of a plurality of nested tubular objects. The guiding axis of the telescopic guide rod 32 is vertically arranged, and the telescopic guide rod 32 can be telescoped in the vertical direction. The feeding plate 33 can move relative to the supporting seat 31 in the vertical direction through the guiding of the telescopic guide rod 32. Refer to Figure 5 , four third working cylinders 191 are arranged below the extrusion head 2 on the supporting platform 19. The axis of the third working cylinder 191 is vertically arranged. When the feeding plate 33 passes below the extrusion head 2, the third working cylinder 191 can push the feeding plate 33 to move upward. A sinking groove 192 is opened on the supporting platform 19, and the third working cylinder 191 is located inside the sinking groove 192. When the third working cylinder 191 is in a contracted state, the third working cylinder 191 is entirely located inside the sinking groove 192 and does not interfere with the transmission of the feeding plate 33. When the third working cylinder 191 is in an extended state, the upper working end of the third working cylinder 191 extends out of the sinking groove 192 and pushes the feeding plate 33 upward.

[0025] After the silt is extruded, a silt model is formed in the silt mold. The silt model is a planting cup 26 for planting underwater plants. Refer to Figure 16 and Figure 18 , the planting cup 26 includes a hemispherical cup body 261. A plurality of filling holes 262 are opened on the side of the cup body 261. The axis of the filling hole 262 is parallel to the central axis of the cup body 261. After the cup body 261 is formed, it is sintered and ceramized. A second filling body 264 can be filled inside the ceramized cup body 261. Underwater plants can be planted in the second filling body 264. The second filling body 264 serves as the original nutrient soil for the underwater plants. The filling holes 262 are used for the roots of the plants to extend out. The planting cup 26 can be used as a carrier for underwater plants when planting underwater plants. After planting the underwater plants in the planting cup 26, the planting cup 26 is then thrown into the water bottom. The planting cup 26 has a certain weight and can sink into the water bottom, which is beneficial for the positioning of the underwater plants at the water bottom. At the same time, the second filling body 264 serves as the original nutrient soil to give the underwater plants preliminary nutrition, which is beneficial for the survival of the underwater plants. The cup body 261 of the planting cup 26 is a ceramic body and can cover the river bottom to reduce underwater disturbance.

[0026] To ensure the stability of the cup body 261 when submerged in water, the inside of the filling hole 262 can be filled with a first filling body 263. The first filling body 263 fills the filling hole 262 to ensure the integrity of the surface of the cup body 261 and reduce the resistance of the cup body 261 during the submerging process.

[0027] The sludge mold includes a first mold 4, a second mold 5, and a third mold 6. A plurality of insertion rods 331 are provided on the above-mentioned feeding plate 33. The insertion rods 331 are used for positioning the first mold 4 and the third mold 6. The number of insertion rods 331 can be set according to processing needs, such as two, four, or six. In this embodiment, the number of insertion rods 331 on the feeding plate 33 is four.

[0028] Reference Figure 10 , the first mold 4 includes a first template 41. Four convex dies 42 are provided on the first template 41. A first insertion hole 43 is provided on the convex die 42. The first insertion hole 43 penetrates the first template 41 from the middle of the convex die 42. The first insertion hole 43 is used for the insertion of the insertion rod 331 on the feeding plate 33 to achieve the positioning of the first mold 4, that is, the combination of the first template 41 and the feeding plate 33.

[0029] Reference Figure 10 and Figure 11 , the second mold 5 includes a second template 51. Four first concave dies 52 are provided on the second template 51. The convex die 42 matches the first concave die 52. The combination of the convex die 42 and the first concave die 52 can form four forming cavities for the cup body 261. A feeding hole 54 for the first sludge feeding is provided at the top of the first concave die 52. The first sludge enters the forming cavity from the feeding hole 54 and forms the cup body 261 inside the forming cavity. A pin 53 is also fixedly provided on the second template 51. The lower end of the pin 53 extends into the inside of the first concave die 52. When the first sludge is formed in the cup body 261, pulling out the pin 53 can form a filling hole 262 on the side of the cup body 261.

[0030] Reference Figure 12 , the third mold 6 includes a third template 61. Four second concave dies 62 and four second insertion holes 63 are provided on the third template 61. The second concave die 62 is used to accommodate the cup body 261. The second insertion hole 63 penetrates the third template 61 from the bottom of the second concave die 62. The second insertion hole 63 is used for the insertion of the insertion rod 331 on the feeding plate 33 to achieve the positioning of the third mold 6, that is, the combination of the third template 61 and the feeding plate 33.

[0031] The above-mentioned first mold 4 can be combined with the second mold 5 or the third mold 6 respectively to be applicable to different extrusion requirements. When extruding the cup body 261, reference Figure 13 , the first mold 4 is combined with the second mold 5, which is the first combination mode of the molds. At this time, the first mold 4 and the second mold 5 are combined to form a first stacked body. When extruding the second filling body 264, reference Figure 14, the first mold 4 is combined with the third mold 6, which is the second combined mode of the molds. At this time, the first mold 4 and the third mold 6 are combined to form the second stacked body.

[0032] A first positioning structure (not shown) is provided between the first mold 4 and the second mold 5. The first positioning structure is used to prevent the first mold 4 and the second mold 5 from shifting in the horizontal direction when combined vertically, avoiding misalignment in the horizontal direction during combination. In the prior art, the positioning structure between the molds often forms a positioning structure in the form of positioning rods and positioning holes. The positioning structure of the positioning rods and positioning holes can be used for positioning between the first mold 4 and the second mold 5. Similarly, a second positioning structure is provided between the first mold 4 and the third mold 6, and the second positioning structure is used to prevent the first mold 4 and the third mold 6 from shifting in the horizontal direction when combined vertically.

[0033] Furthermore, an extrusion barrel 13 is fixedly provided on the support frame 27. A screw rod 131 is arranged inside the extrusion barrel 13. The screw rod 131 can extrude the sludge inside the extrusion barrel 13 by rotation. A third motor 132 is arranged on the support frame 27. The output shaft of the third motor 132 is fixedly connected to the screw rod 131. The third motor 132 can drive the screw rod 131 to rotate, forming the extrusion action of the sludge. Refer to Figure 2 and Figure 3 , the extrusion barrel 13 is provided with two feed channels and one discharge channel. The discharge channel is communicated with the extrusion head 2. The discharge port of the extrusion head 2 is configured with two discharge plates, which are the first discharge plate 7 and the second discharge plate 8 respectively. The first discharge plate 7 and the second discharge plate 8 are fixedly connected, and the first discharge plate 7 and the second discharge plate 8 are slidably connected to the extrusion head 2. The support frame 27 is further provided with a first working cylinder 14. The working end of the first working cylinder 14 is connected to the first discharge plate 7 or the second discharge plate 8. The axis of the first working cylinder 14 is horizontally arranged. The first working cylinder 14 is used to drive the first discharge plate 7 and the second discharge plate 8 to move in the horizontal direction, realizing the combination of the first discharge plate 7 and the extrusion head 2 or the combination of the second discharge plate 8 and the extrusion head 2.

[0034] Refer to Figure 5, a first discharge plate 7 is provided with a first discharge hole 71, and the position of the first discharge hole 71 corresponds to the position of a feed hole 54 on a second template 51. When the second mold 5 passes through the first discharge plate 7 combined with the extrusion head 2, a third working cylinder 191 extends, and can lift the feed plate 33 and the first mold 4 and the second mold 5 thereon, so that the feed hole 54 on the second template 51 contacts and communicates with the first discharge hole 71 on the first discharge plate 7. The first sludge is extruded from the first discharge hole 71, passes through the feed hole 54 and enters the forming cavity between the first mold 4 and the second mold 5 to form a model of a cup body 261. After extrusion is completed, the third working cylinder 191 contracts, the feed hole 54 on the second template 51 is separated from the first discharge hole 71 on the first discharge plate 7, and a model of the cup body 261 is obtained on the feed plate 33.

[0035] Reference Figure 3 , a cutting knife 20 is provided on the lower surface of the first discharge plate 7. The cutting knife 20 is connected to a support frame 27 through a second working cylinder 21. The axis of the second working cylinder 21 is horizontally arranged, and the second working cylinder 21 can push the cutting knife 20 to move in the horizontal direction to cut the sludge after extrusion is completed.

[0036] Reference Figure 5 , a sealing cover 201 is further provided above the extrusion head 2. A communication hole 202 is provided at the top of the extrusion head 2. The inside of the sealing cover 201 communicates with a negative pressure pipe 203 and the top space of the extrusion head 2. The negative pressure pipe 203 communicates with a negative pressure pump to form a negative pressure. When the extrusion head 2 is not extruding, the sealing cover 201 can form a negative pressure at the top of the extrusion head 2 to prevent sludge from leaking out of the discharge plate.

[0037] Further, the second discharge plate 8 is provided with four bearing platforms 81. The bearing platforms 81 are rotatably connected to the second discharge plate 8. The number and position of the bearing platforms 81 correspond to the number and position of the convex dies 42 on the first mold 4. The second discharge plate 8 corresponds to the first mold 4 in position, and the bearing platforms 81 are coaxial with the convex dies 42. A plurality of discharge pipes 82 are fixedly provided on the bearing platforms 81. The pipe holes of the discharge pipes 82 are second discharge holes 83. The second discharge holes 83 are annularly distributed on the bearing platforms 81, and the positions of the second discharge holes 83 correspond to the positions of the filling holes 262.

[0038] The lower part of the above-mentioned carrier table 81 extends out from the second discharge plate 8. A gear ring 84 is sleeved on the extended part of the carrier table 81. A rack 85 is arranged on the second discharge plate 8, and the rack 85 meshes with the gear ring 84. The rack 85 is slidably connected to the second discharge plate 8. A fourth working cylinder (not shown) is also fixedly arranged on the second discharge plate 8. The axis of the fourth working cylinder is horizontally arranged, and the working end of the fourth working cylinder is connected to the rack 85. The fourth working cylinder is used to drive the rack 85 to move in the horizontal direction. The movement of the rack 85 can drive the gear ring 84, the carrier table 81, and the second discharge hole 83 to generate a rotational movement, which is used to cut off the second sludge after extruding the first filling body 263.

[0039] Reference Figure 6 and Figure 7 , when the first mold 4 passes through the second discharge plate 8 combined with the extrusion head 2, the third working cylinder 191 extends, and the feeding plate 33 and the first mold 4 thereon can be lifted, so that the surface of the sintered cup body 261 on the first mold 4 contacts the lower end of the discharge pipe 82. The filling hole 262 on the cup body 261 communicates with the second discharge hole 83 on the second discharge plate 8, and the second sludge is extruded from the second discharge hole 83 into the filling hole 262 of the cup body 261 to form the first filling body 263. The outer diameter of the discharge pipe 82 is larger than the diameter of the filling hole 262, and the discharge pipe 82 always contacts the surface of the cup body 261 and does not extend into the filling hole 262. After extrusion, the fourth working cylinder drives the rack 85 to reciprocate horizontally once, the gear ring 84 and the carrier table 81 rotate 360° forward and backward relative to the second discharge plate 8, and the second discharge hole 83 moves relative to the cup body 261, realizing the separation of the second sludge inside the second discharge hole 83 from the first filling body 263. After the rotation of the carrier table 81 is completed, the third working cylinder 191 contracts, and the cup body 261 on the first mold 4 is separated from the discharge pipe 82 on the second discharge plate 8, and the first filling body 263 is formed inside the filling hole 262 of the cup body 261.
