[0024] like Figures 1 to 6 As shown, the present invention provides a channel dredged soil processing device, comprising: A walking mechanism 1 is provided with a base 2, a discharge channel 15 is provided on the base 2, and a switch valve 20 is provided on the discharge channel 15; specifically, the walking base 2 can be a crawler walking mechanism 1, a wheeled walking mechanism 1, a semi-crawler walking mechanism 1 or other walking mechanism, and the walking mechanism 1 moves forward to drive the base 2 to walk on a drying field where dredged soil is dried, and the switch valve 20 can be composed of a rotary driver 16, a rotary shaft 17, a valve plate 18, and a sealing strip 19, and can also be a common valve for controlling circulation, and the switch valve 20 is used to control the connection and closing of the discharge channel 15 with the carbon canister 3 described below or the space at the bottom of the base 2; A charcoal canister 3 is disposed on the base 2. The charcoal canister 3 contains activated carbon powder. The charcoal canister 3 is provided with a charcoal powder outlet connected to the inlet end of the discharge channel 15. Specifically, the charcoal canister 3 can be welded to the base 2 or directly placed on the base 2. The activated carbon powder can be made by burning biomass such as coconut shells and straws. The switch valve 20 is opened to open the discharge channel 15, and the activated carbon powder contained in the charcoal canister 3 can be discharged from the charcoal powder outlet. The crushing plate 4 is disposed on the base 2 and is slidable up and down toward the ground. The crushing plate 4 is located in front of the carbon canister 3. When the crushing plate 4 moves downward to a certain distance, it abuts against the dredged soil block. Specifically, the crushing plate 4 can be made of stainless steel or carbon steel to have a certain hardness and strength. When it abuts against the dredged soil block, the dredged soil block is crushed. The crushing plate 4 can slide up and down under the drive of the linear drive 13. The crushing plate 4 moves downward until it abuts against the dredged soil block, crushing the dredged soil block. The crushing plate 4 is slidably arranged on the base 2, so that the crushing plate 4 moves forward along with the base 2, and in the process of the moving mechanism 1 moving forward, the crushing plate 4 continuously slides up and down to crush the dredged soil blocks, thereby crushing all the dredged soil blocks in a row that are dried, and the arrangement of the positions of the crushing plate 4 and the charcoal canister 3 facilitates the activated carbon powder in the charcoal canister 3 to cover the surface of the crushed dredged soil, thereby realizing that the activated carbon powder inhibits the reproduction of pathogens in the dredged soil, and plays a role in disinfection and sterilization; The coating structure includes a coating roller 5 rotatably arranged on the base 2, a rotary drive unit 12 driving the coating roller 5 to rotate, and a covering film 23 wound on the coating roller 5. The coating roller 5 is located at the rear of the carbon canister 3, and the axial direction of its rotating shaft is horizontally perpendicular to the travel direction of the walking mechanism 1. A water-absorbing layer 24 is applied on the inner side of the covering film 23. Specifically, the covering film 23 can be a black high-temperature resistant film that can effectively absorb the energy of sunlight. The coating roller 5 can be rotated on the base 2 by a pair of upright support plates 6 and bearings. The rotary drive unit 12 can be a rotary motor, a rotary cylinder, or a shaft 10, a first transmission wheel 9, a second transmission wheel 7, a transmission belt 11. The coating roller 5 is composed of: starting the rotary drive unit 12, the rotary drive unit 12 drives the coating roller 5 to rotate, and the coating roller 5 rotates, and with the help of human power (the head end of the coating film 23 needs to be pulled with a certain force), the coating film 23 wrapped around the coating roller 5 is unfolded, and the axial arrangement of the rotating shaft of the coating roller 5 makes the unfolded length direction of the coating film 23 the same as the travel direction of the walking mechanism 1, so that it is convenient to cover the crushed dredged soil, and the material of the water absorption layer 24 can be sponge, cotton cloth or calcium oxide. The water absorption layer 24 is used to absorb the water vapor generated by covering the coating film 23 and the water vapor evaporated from the moist part of the dredged soil, so as to prevent the generated water vapor from continuing to affect the drying of the dredged soil.

[0025] In the above technical scheme, the dredged soil in the drying yard is agglomerated after drying, and the dredged soil in the middle is still wet after the surface layer of the agglomerated dredged soil is dried. The walking mechanism 1 is used to drive the base 2 to move forward on the drying yard. During the advancement of the walking mechanism 1, the linear drive 13 can be used to drive the crushing plate 4 to continuously move up and down, and in the process of moving downward, it abuts against the dredged soil blocks to crush the dredged soil blocks, leaving the wet part in the middle exposed. During the advancement of the walking mechanism 1, the switch valve 20 is opened. The discharge channel 15 is in an open state, and the activated carbon powder in the carbon tank 3 is continuously discharged and covers the surface of the crushed dredged soil. Then, the coating roller 5 is driven to rotate by the rotary drive unit 12, and the coating film 23 is unfolded with the help of manual assistance and covers the dredged soil that has been covered with activated carbon, completing the crushing and covering of a row of dredged soil. By repeating the above operation, the covering of the dredged soil on the drying field can be completed. The position setting among the carbon tank 3, the crushing plate 4, and the coating structure is helpful to During the forward movement of the walking mechanism 1, the crushing plate 4 is first used to crush the dredged soil blocks, and then the activated carbon powder on the carbon tank 3 is covered on the crushed dredged soil surface through the discharge channel 15 and the switch valve 20, and then the covering film 23 is covered on the dredged soil covered with the activated carbon powder through the covering film structure. The sequence of first crushing, then laying the activated carbon powder, and then covering the covering film 23 is conducive to the activated carbon powder directly acting on the moist part of the dredged soil (the part where bacteria exist), and can be used for disinfection and sterilization. The performance has a certain disinfecting effect on bacteria, insect eggs, etc. in the dredged soil, and covering the covering film 23 helps to place the moist dredged soil in a relatively closed space, which can not only reduce the contact of insect eggs with air, but also increase the temperature of the dredged soil under the covering film 23, accelerate the evaporation of water in the moist dredged soil, and be absorbed by the water absorption layer 24, accelerate the drying of the dredged soil, save drying time, and the increase in the temperature of the dredged soil can further enhance the killing of bacteria, insect eggs, etc., wherein the density of the activated carbon powder covering is 200~300 kg / hm 2 Optimum, crushed dredged soil at 200~300 kg / hm 2 + Under the action of the covering film 23, at 14 o'clock when the sun is at its peak, the temperature of the dredged soil surface can reach above 60°C, which can effectively kill bacteria, insect eggs, etc. The setting of the water-absorbing layer 24 absorbs the water vapor generated by covering the covering film 23 and the water vapor evaporated from the moist part of the dredged soil, which is beneficial to reduce the moisture of the crushed dredged soil.

[0026] In another technical solution, support plates 6 are provided on both sides of the base 2; It also includes a rotating shaft 8, both ends of which are rotatably arranged on a pair of support plates 6, and the coating roller 5 is fixedly sleeved on the rotating shaft 8; specifically, the support plate 6 can be made of stainless steel, carbon steel or concrete to have a certain hardness and strength to provide support for the rotating shaft 8 described below. A pair of support plates 6 can be erected on both sides of the base 2 by welding, and the rotating shaft 8 can be rotatably arranged on the support plate 6 through a through hole opened on the support plate 6 and a bearing arranged on the through hole. The arrangement of the support plate 6 and the rotating shaft 8 helps the covering film 23 to be rotatably arranged on the base 2.

[0027] In another technical solution, the traveling mechanism 1 is a wheeled traveling mechanism 1; specifically, the wheeled traveling mechanism 1 travels via wheels, which makes it easier to travel on a relatively flat drying field.

[0028] In another technical solution, both ends of the rotating shaft 8 are correspondingly penetrated on a pair of support plates 6 and extend out of the support plates 6; The wheels of the walking mechanism 1 are located outside the base 2; The rotary drive unit 12 includes: A pair of shafts 10, the pair of shafts 10 are coaxially convexly arranged on the outer sides of the two rear wheels of the traveling mechanism 1, and the first transmission wheel 9 is coaxially sleeved on the shafts 10; specifically, the shafts 10 can be coaxially convexly arranged on the outer sides of the rear wheels of the traveling mechanism 1 by welding, and when the traveling mechanism 1 is moving forward, the rear wheels rotate, driving the shafts 10 to rotate, and then driving the first transmission wheel 9 coaxially sleeved on the shafts 10 to rotate; A pair of second transmission wheels 7 are fixedly sleeved on both ends of the rotating shaft 8 respectively, and a transmission belt 11 is sleeved on the second transmission wheel 7 and the first transmission wheel 9 located on the same side of the base 2; specifically, the second transmission wheel 7 can be fixedly sleeved on the rotating shaft 8 by welding or screwing, and the first transmission wheel 9 rotates, and the transmission belt 11 utilizes the friction force between the first transmission wheel 9 and the transmission belt 11 to transmit the force of the rotation of the first transmission wheel 9 to the second transmission wheel 7, so that it rotates, thereby driving the rotating shaft 8 to rotate, thereby driving the coating roller 5 to rotate.

[0029] In the above technical solution, a pair of shafts 10 are coaxially convexly arranged on the outer sides of the two rear wheels of the walking mechanism 1, and the transmission belt 11 is used to connect the second transmission wheel 7 and the first transmission wheel 9 on the same side. When the walking mechanism 1 is moving forward, the rear wheels rotate to drive the shaft 10 to rotate coaxially. The shaft 10 rotates, and then drives the first transmission wheel 9 to rotate. The transmission belt 11 uses the friction between the first transmission wheel 9 and the transmission belt 11 to transmit the force of the first transmission wheel 9 to rotate to the second transmission wheel 7, so that it rotates, and then drives the rotating shaft 8 to rotate, thereby driving the coating roller 5 to rotate. The shaft 10, the first transmission wheel 9 The arrangement of the transmission belt 11, the second transmission wheel 7 and the rotating shaft 8 is helpful to realize the use of the wheels of the walking mechanism 1 to drive the rotation of the coating roller 5, and can effectively utilize the energy of the walking mechanism 1. Among them, the wheel position arrangement of the walking mechanism 1 and the arrangement of the rotating shaft 8 passing through the support plate 6 provide feasibility for the wheels of the walking mechanism 1 to drive the rotation of the coating roller 5. When the covering film 23 is not needed, when the walking mechanism 1 stops, the connection between the coating roller 5 and the wheel of the walking mechanism 1 can be disassembled by taking out the transmission belt 11. When the walking mechanism 1 moves forward subsequently, the covering film 23 will not unfold as the walking mechanism 1 moves forward.

[0030] In another technical solution, the length of the outlet end of the discharge channel 15 parallel to the axial direction of the coating roller 5 is equal to the length of the crushing plate 4 parallel to the axial direction of the coating roller 5, and the length of the covering film 23 parallel to the axial direction of the coating roller 5 is greater than the length of the crushing plate 4 parallel to the axial direction of the coating roller 5; specifically, the length of the outlet end of the discharge channel 15 and the length of the crushing plate 4 are helpful to lay the activated carbon powder on the crushed dredged soil in an equal length parallel to the axial direction of the coating roller 5, which can effectively save the use of activated carbon powder, and the setting of the length of the covering film 23 and the crushing plate 4 ensures that the covering film 23 can completely cover the crushed dredged soil during the forward movement of the walking mechanism 1, so that the dredged soil crushed by the crushing plate 4 is completely located in the closed space.

[0031] In another technical solution, a discharge hopper 21 is provided on the discharge channel 15, and a strip-shaped discharge port 22 is opened on the discharge hopper 21 to form the outlet end of the discharge channel 15; specifically, the discharge hopper 21 is welded to the bottom end of the discharge channel 15, and the bottom of the discharge hopper 21 may be in a convex arc shape, which is conducive to the rotation of the rotating shaft 17 and the valve plate 18 described below; The switch valve 20 comprises: A rotary driver 16, whose fixed end is disposed on the discharge channel 15 and is located above the discharge hopper 21, and the output shaft of the rotary driver 16 is parallel to the axial direction of the coating roller 5; specifically, the rotary driver 16 can be a rotary motor, a rotary cylinder or a rotary oil cylinder, and the fixed end of the rotary driver 16 can be fixed on the side wall of the discharge channel 15 by welding, and the rotary driver 16 is started, and the output shaft of the rotary driver 16 rotates; A rotating shaft 17 is coaxially arranged on the output shaft of the rotating driver 16. At least two valve plates 18 are convexly arranged on the rotating shaft 17 along its circumference. A sealing strip 19 is arranged on one side of the valve plate 18. The material of the sealing strip 19 is flexible. Specifically, the two valve plates 18 are asymmetrically arranged. The valve plates 18 can be convexly arranged on the rotating shaft 17 by welding or screwing. The sealing strip 19 can be fixed on one side of the valve plate 18 by bonding. The output shaft of the rotating driver 16 rotates, driving the rotating shaft 17 to rotate, and then driving the valve plates 18 and the sealing strip 19 to rotate. When the valve plate 18 rotates to the first position, the sealing strip 19 blocks the strip-shaped discharge port 22 or the inlet end of the discharge channel 15, and the discharge channel 15 is closed; When the sealing strip 19 rotates to a position other than the first position, the sealing strip 19 does not block the strip-shaped discharge port 22 and the inlet end of the discharge channel 15 , and the discharge channel 15 is opened.

[0032] In the above technical solution, the discharge hopper 21 is arranged at the bottom of the discharge channel 15. When the activated carbon powder in the carbon canister 3 is not needed, the valve plate 18 is in the first position, that is, the sealing strip 19 is blocked at the strip-shaped discharge port 22 or the inlet end of the discharge channel 15. At this time, the discharge channel 15 is closed, and the carbon powder outlet of the carbon canister 3 is not connected to the outside. When the activated carbon powder in the carbon canister 3 needs to be used, the rotary driver 16 is started, and the output shaft of the rotary driver 16 rotates, driving the rotary shaft 17 to rotate, thereby driving the valve plate 18 and the activated carbon powder in the carbon canister 3 to rotate. The sealing strip 19 rotates until the sealing strips 19 on the two valve plates 18 are neither blocked on the strip-shaped discharge port 22 nor on the inlet end of the discharge channel 15, the discharge channel 15 is opened, the carbon powder outlet of the carbon canister 3 is connected with the outside, and the activated carbon powder can be discharged and covered on the surface of the crushed dredged soil. The switch valve 20 formed by the discharge hopper 21, the rotating shaft 17, the valve plate 18, and the sealing strip 19 helps to avoid part of the activated carbon powder being clamped in the gap when opening or closing the switch valve 20 like a traditional horizontal pull-out valve.

[0033] In another technical solution, it also includes a linear drive 13, a fixed end of which is arranged on the top of the base 2, and a moving end of the linear drive 13 slides up and down through the base 2. A connecting rod 14 is provided on the moving end of the linear drive 13, and the lower end of the connecting rod 14 is provided with the crushing plate 4; specifically, the linear drive 13 can be a linear motor, an electric push rod or a hydraulic rod, and the fixed end of the linear drive 13 can be fixed on the top of the base 2 by welding or screwing, and the moving end of the linear drive 13 can slide up and down through the base 2 through a through hole opened on the base 2, and the linear drive 13 is started, and the moving end of the linear drive 13 moves up and down, driving the connecting rod 14 to move up and down, thereby realizing the up and down movement of the crushing plate 4, thereby applying pressure to the block-shaped dredged soil, abutting against the dredged soil block, crushing it, and making the wet dredged soil in the middle part naked.

[0034] In another technical solution, the upper wall of the rear end of the base 2 is in a convex arc shape; specifically, the upper wall of the rear end of the base 2 is in an arc shape, which helps to avoid sharp contact with the rear end of the base 2 after the covering film 23 is unfolded, thereby preventing the covering film 23 from being scratched and failing to effectively cover the activated carbon powder and crushed dredged soil.

[0035] In another technical solution, the water-absorbing layer 24 is a calcium oxide layer, and a non-woven fabric 25 is applied to the side of the water-absorbing layer 24 away from the covering film 23; specifically, the non-woven fabric 25 has a breathable function, and the covering film 23 covers the activated carbon powder and the crushed dredged soil. The high temperature generated will cause the moisture in the crushed dredged soil to evaporate into water vapor, and the water vapor rises and passes through the non-woven fabric 25, so that the water-absorbing layer 24 absorbs it, which is beneficial to reduce the moisture generated by the crushed dredged soil due to covering the covering film 23. After the calcium oxide layer absorbs the water vapor, it will chemically react with the water vapor to generate a large amount of heat, which will further increase the temperature of the dredged soil under the covering film 23, which is more conducive to the killing of insect eggs and bacteria. The non-woven fabric 25 also has the advantage of not supporting combustion, and will not cause excessive temperature due to excessive heat generation to create a fire hazard.

[0036] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
