[0002] Plastic drainage belts, also called plastic drainage boards by many people, are a commonly used soft foundation treatment material. They have various shapes such as wave type and harmonica type. In the middle is an extruded plastic core board, which is the skeleton and channel of the drainage belt. Its cross-section is in a parallel cross shape, and both sides are wrapped with non-woven geotextiles as filter layers. The core belt plays a supporting role and discharges the water seeping in from the filter layer upward. It is a good vertical channel for soft foundation treatment of saturated cohesive soils such as silt, muddy soil, and fill soil, as well as miscellaneous fill soils using the drainage consolidation method, greatly shortening the soft soil consolidation time. The existing drainage boards are mainly made of polystyrene or polyethylene, and such drainage boards are difficult to decompose and are not conducive to environmental protection.

[0030] Embodiment:

[0031] Please refer to Figure 1-8, the present invention provides a technical solution: a plant straw drainage board production device for an assembly line, including a feeding device 1, a first assembly line 8, a metal suction mechanism 9, a forming mechanism 10, a second assembly line 11, and a cutting mechanism 12. The feeding device 1 is connected to an upper conveying mechanism 3 through a pipeline. Materials such as plant straws are added to the feeding device 1, and the feeding device 1 conveys the materials to the upper conveying mechanism 3. The upper conveying mechanism 3 preliminarily preheats the materials. On the upper left side of the upper conveying mechanism 3, there is a heat-conducting oil pipe 4 connected. High-temperature hot oil from the outside enters the upper conveying mechanism 3 through the heat-conducting oil pipe 4. The high-temperature hot oil can fully heat the materials in the upper conveying mechanism 3. On the lower left side of the upper conveying mechanism 3, there is a pre-crushing mechanism 5 connected. The pre-crushing mechanism 5 can preliminarily crush the materials flowing out of the upper conveying mechanism 3, thus avoiding the condensation of materials into blocks and further avoiding the blockage of the lower conveying mechanism 6. The lower side of the pre-crushing mechanism 5 is connected to a lower conveying mechanism 6. The preliminarily crushed materials fall into the lower conveying mechanism 6 under the action of gravity. On the lower left side of the lower conveying mechanism 6, there is a material crushing mechanism 7 connected. The lower conveying mechanism 6 is responsible for conveying the materials to the material crushing mechanism 7. The distance between the upper end of the material crushing mechanism 7 and the lower end of the pre-crushing mechanism 5 is less than 15 cm. The first assembly line 8 is located on the lower side of the material crushing mechanism 7. The first assembly line 8 conveys the crushed materials to the upper end of the forming mechanism 10. The metal suction mechanism 9 is located on the right side of the first assembly line 8. The metal suction mechanism 9 can suck away the iron in the falling materials. The forming mechanism 10 is located on the lower right side of the first assembly line 8. The forming mechanism 10 extrudes and forms the materials. The formed materials fall onto the second assembly line 11. The second assembly line 11 is located on the lower side of the forming mechanism 10. The second assembly line 11 conveys the formed materials to the cutting mechanism 12. The cutting mechanism 12 is located on the left side of the second assembly line 11. The cutting mechanism 12 cuts off the waste materials on the formed materials.

[0032] The upper conveying mechanism 3 includes a conveying pipeline 33. An outer side of the conveying pipeline 33 is sleeved with a heating sleeve 32. The heating sleeve 32 can preliminarily preheat the materials in the conveying pipeline 33. Inside the cavity of the conveying pipeline 33, a feeding screw 31 is movably arranged. The feeding screw 31 is driven by an electric motor. The pitch of the feeding screw 31 gradually decreases from left to right. The minor diameter of the thread of the feeding screw 31 gradually decreases from left to right. The major diameter of the thread of the feeding screw 31 remains unchanged. The materials contain adhesives, and the viscosity of the adhesives increases with the increase of temperature. The gradual change of the pitch and the minor diameter of the thread of the feeding screw 31 can increase the conveying capacity of the feeding screw 31, thus avoiding the blockage of the conveying pipeline 33 by the materials.

[0033] The lower conveying mechanism 6 includes a feeding pipe 63. A heat preservation sleeve 62 is sleeved outside the feeding pipe 63. The heat preservation sleeve 62 can keep warm, thereby reducing the heat dissipation in the lower conveying mechanism 6. A feeding screw 61 is movably arranged in the inner cavity of the feeding pipe 63. The pitch of the feeding screw 61 gradually increases from left to right, the minor diameter of the thread of the feeding screw 61 gradually increases from left to right, and the major diameter of the thread of the feeding screw 61 remains unchanged. The material contains an adhesive, and the adhesive begins to gradually solidify as the temperature decreases. The gradual change of the pitch and the minor diameter of the thread of the feeding screw 61 can increase the conveying speed of the feeding screw 61, thereby preventing the material in the feeding pipe 63 from solidifying.

[0034] An observation door 51 is arranged on the front side of the body of the pre-crushing mechanism 5. The left end of the observation door 51 is connected to the body of the pre-crushing mechanism 5 through a hinge. Opening the observation door 51 can observe the crushing state of the material in the pre-crushing mechanism 5.

[0035] A feeding port 72 is arranged on the upper right side of the crushing mechanism 7. The feeding port 72 is communicated with the lower conveying mechanism 6. A compensation port 71 is arranged on the upper left side of the crushing mechanism 7. When the material in the crushing mechanism 7 is less, the material can be added to the crushing mechanism 7 through the compensation port 71. An outlet 73 is opened below the body of the crushing mechanism 7. The outlet 73 is parallel to the upper surface of the first production line 8, and both the outlet 73 and the upper surface of the first production line 8 are horizontal, so that the material flowing out of the crushing mechanism 7 can fall flat on the first production line 8.

[0036] The metal suction mechanism 9 includes a fixed table 91. A rotating table 92 is installed above the fixed table 91. A support cantilever 93 is arranged outside the rotating table 92. The other end of the support cantilever 93 is connected with a strong magnet 94. The leftmost strong magnet 94 is responsible for sucking iron metal in the material. By rotating the rotating table 92, the rotating table 92 can drive the support cantilever 93 to rotate, and the support cantilever 93 can drive the strong magnet 94 to rotate. By rotating the strong magnet 94, the strong magnet 94 for sucking metal can be replaced.

[0037] The forming mechanism 10 includes two forming brackets 101, a cooling pool 103 and a forming motor 105. An active gear 107 is sleeved outside the rotor of the forming motor 105. A forming guide roller 102 is movably connected between the two forming brackets 101. The number of the forming guide rollers 102 is two. The two forming guide rollers 102 are used for the extrusion forming of the drainage board. The rear side of the forming guide roller 102 penetrates through the rear forming bracket 101. Driven gears 106 are sleeved outside the rear ends of the two forming guide rollers 102. One of the driven gears 106 meshes with the active gear 107, and this driven gear 106 also meshes with the other driven gear 106. A cooling pump 104 is placed inside the cooling pool 103. The cooling pump 104 is communicated with the front side of the inner cavity of the forming guide roller 102 through a pipeline. The rear side of the inner cavity of the forming guide roller 102 is communicated with the cooling pool 103 through a pipeline. Rotary joints are connected to the front and rear ends of the forming guide roller 102. The pipeline is connected to the rotary joint. Cooling water is added to the cooling pool 103. The forming guide roller 102 can be cooled by the cooling water. Reducing the temperature of the forming guide roller 102 can reduce the viscosity of the material to the forming guide roller 102, thereby facilitating the separation of the material from the forming guide roller 102.

[0038] The forming guide roller 102 includes a main pressing roller 1021. Auxiliary pressing rollers 1022 are arranged on the front and rear sides of the main pressing roller 1021. Shallow grooves 1024 are formed on the outer sides of the bodies of the front and rear auxiliary pressing rollers 1022. A deep groove 1023 is formed on the outer side of the body of the main pressing roller 1021. The diameter of the main pressing roller 1021 is larger than that of the auxiliary pressing roller 1022. The pressure at the front and rear ends is relatively small, which can concentrate the waste of the drainage board at the front and rear ends of the drainage board. The waste at both ends can facilitate the removal of the waste. The distance between two adjacent deep grooves 1023 is smaller than the distance between two adjacent shallow grooves 1024.

[0039] A sealing chamber 2 is arranged outside the feeding device 1. A large amount of dust will be generated when the feeding device 1 is feeding. Placing the feeding device 1 in the sealing chamber 2 can prevent dust from entering the atmosphere, thereby reducing pollution.

[0040] Working principle: Add materials such as plant straws to the feeding device 1, and then add the materials to the upper conveying mechanism 3 through the feeding device 1. At the same time, add hot oil to the upper conveying mechanism 3 through the heat-conducting oil pipe 4. The hot oil can heat the materials in the upper conveying mechanism 3. Then add the materials to the preliminary crushing mechanism 5 through the upper conveying mechanism 3. The preliminary crushing mechanism 5 conducts preliminary crushing on the materials. The crushed materials enter the lower conveying mechanism 6 under the action of gravity. Then the lower conveying mechanism 6 conveys the materials to the material crushing mechanism 7. The material crushing mechanism 7 crushes the materials. Then the crushed materials in the material crushing mechanism 7 fall onto the first production line 8 under the action of gravity. The first production line 8 conveys the materials to the upper end of the forming mechanism 10. Then the materials fall into the forming mechanism 10 under the action of gravity. The metal removal mechanism 9 can suck away the iron in the falling materials. The forming mechanism 10 extrudes and forms the materials. The formed materials fall onto the second production line 11 under the action of gravity. The second production line 11 conveys the materials to the cutting mechanism 12. The cutting mechanism 12 cuts off the waste on the formed materials.
