Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation mixing devices, and particularly relates to a mixing device for cadmium-polluted farmland soil remediation. Background Technique

[0002] Cadmium is a heavy metal element that poses significant hazards to the environment and human health. In farmland soil, cadmium pollution mainly comes from industrial emissions, agricultural activities (such as the use of chemical fertilizers and pesticides), sewage irrigation, and atmospheric deposition, etc. When the cadmium content in the soil exceeds a certain limit, it will have a serious impact on crop growth and the soil ecosystem. Therefore, soil remediation is required.

[0003] When mixing the materials used for the repaired land, since it is necessary to manually take them out from the inside of the machine after mixing, the work efficiency is reduced. At the same time, the workload of the staff is increased, and a large amount of time is required to take out the materials. Therefore, we have proposed a mixing device for cadmium-polluted farmland soil remediation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mixing device for cadmium-polluted farmland soil remediation. After the materials are mixed, due to the setting of the rotating block and the first fixing rod, by moving the pull rod, the fixing plate rotates downward, and the internal materials are directly poured out. Then, by lifting it upward, under the action of the limiting ring, the fixing plate maintains its original angle, which is convenient for taking out the materials, solving the problem that after the existing mixing is completed, it is necessary to manually take it out from the inside of the machine, which reduces the work efficiency, increases the workload of the staff, and requires a large amount of time to take out the materials.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a mixing device for cadmium-polluted farmland soil remediation, including support legs. The top of the support legs is fixedly connected with support rods. The top of the support rods is fixedly connected with a first fixing block. A rotating hole is opened on the front surface of the first fixing block. The inner wall of the rotating hole is in contact with a first fixing rod. A rotating block is fixedly connected to the outer surface of the first fixing rod. The top of the rotating block is fixedly connected with a fixing plate. A pull rod is fixedly connected to the left side of the fixing plate. An arc-shaped limiting ring is fixed on the right side of the support rod. By setting the first fixing rod, specifically, after the materials are mixed, due to the setting of the rotating block and the first fixing rod, by moving the pull rod, the fixing plate rotates downward, and the internal materials are directly poured out. Then, by lifting it upward, under the action of the limiting ring, the fixing plate maintains its original angle, which is convenient for taking out the materials, making the device more convenient to use, reducing the workload of the staff, and improving the work efficiency.

[0007] A limiting rod is fixedly connected to the bottom of the fixed plate. The limiting rod is opposite to the position of the limiting ring, and the limiting rod can be inserted into the limiting ring. The limiting rod is arc-shaped. The number of the rotating blocks is two, and the two rotating blocks are symmetrically arranged with the first fixed block as the center. The limiting ring is arc-shaped. The arrangement of the limiting ring enables the overall device to be angle-limited, making the device more stable during operation and reducing the tremor during device operation.

[0008] Furthermore, a rotating shaft is fixedly connected to the output end on the right side of the fixed plate. A first rotating block is fixedly connected to the right side of the rotating shaft. A transmission belt is connected to the outer surface of the first rotating block in a transmission manner. A second rotating block is arranged above the fixed plate. The first rotating block is in transmission connection with the second rotating block through the transmission belt. A mixing barrel is fixedly connected to the left side of the second rotating block. The arrangement of the transmission belt enables the first rotating block to drive the second rotating block to rotate synchronously while rotating.

[0009] Furthermore, fixing pieces are fixedly connected to the inner wall of the mixing barrel. Mixing blades are arranged on the back of the fixing pieces. The number of the fixing pieces is several. A support frame is fixedly connected to the top of the fixed plate. A second fixed rod is fixedly connected to the left side of the support frame. In this utility model, by setting the fixing pieces, specifically, by starting the motor, the first rotating block drives the mixing barrel to rotate. At the same time, due to the several fixing pieces and mixing blades arranged inside, the materials inside can be mixed, and the device mixes the materials more evenly during the mixing process, eliminating the need for manual mixing and saving a large amount of time and labor.

[0010] Furthermore, pulleys are rotatably connected to the outer surface of the second fixed rod. The number of the second fixed rods is two, and the two second fixed rods are symmetrically arranged with the mixing barrel as the center. The number of the mixing blades is several. The arrangement of the mixing blades makes the materials mix more evenly in the mixing barrel.

[0011] Furthermore, a second fixed block is fixedly connected to the top of the fixed plate. A first runner is rotatably connected to the left side of the second fixed block through a pin shaft. A rotating groove is formed on the outer surface of the first runner. The inner wall of the rotating groove is in contact with the outer surface of the fixed ring. A limiting plate is arranged on the right side of the second fixed block. A second runner is rotatably connected to the right side of the limiting plate through a pin shaft. The number of the limiting plates is two, and the two limiting plates are symmetrically arranged with the second runner as the center. The combination of the first runner and the fixed ring is used to prevent the mixing barrel from disengaging from this position during rotation.

[0012] This utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a first fixing rod. Specifically, after the materials are mixed, due to the rotation block and the first fixing rod, by moving the pull rod, the fixing plate rotates downward to directly pour out the internal materials.

[0025] Please refer to Figures 1-5 As shown in the figure, the present utility model is a mixing device for cadmium-polluted farmland soil remediation, including a support leg 1. The top of the support leg 1 is fixedly connected with a support rod 11. The top of the support rod 11 is fixedly connected with a first fixing block 12. A rotating hole is opened on the front surface of the first fixing block. The inner wall of the rotating hole is in contact with a first fixing rod 121.

The left side of the fixing plate 21 is fixedly connected with a pull rod 23. The right side of the support rod 11 is fixedly in contact with a limiting ring 221. By setting the first fixing rod 121 in the present utility model, specifically, after the materials are mixed, due to the setting of the rotating block 2 and the first fixing rod 121, by moving the pull rod 23, the fixing plate 21 is rotated downward to directly pour out the internal materials. Then, by lifting it upward, under the action of the limiting ring 221, the fixing plate 21 maintains its original angle, which is convenient for taking out the materials, making the device more convenient to use, reducing the workload of the staff, and improving work efficiency.

[0026] The bottom of the fixing plate 21 is fixedly connected with a limiting rod 22. The left side of the limiting rod 22 can be inserted into the right side of the limiting ring 221. The limiting rod 22 is arc-shaped. The number of rotating blocks 2 is two. The two rotating blocks 2 are symmetrically arranged with the first fixing block 12 as the center. The limiting ring 221 is arc-shaped.

[0027] The output end on the right side of the fixing plate 21 is fixedly connected with a rotating shaft 31. The right side of the rotating shaft 31 is fixedly connected with a first rotating block 32. The outer surface of the first rotating block 32 is drivingly connected with a transmission belt 33. Above the fixing plate 21, there is a second rotating block 34. The first rotating block 32 is drivingly connected with the second rotating block 34 through the transmission belt 33. The left side of the second rotating block 34 is fixedly connected with a mixing barrel 341.

[0028] A fixing piece 43 is fixedly connected to the inner wall of the mixing barrel 341. A mixing blade 44 is arranged on the back of the fixing piece 43. The number of the fixing pieces 43 is several. A support frame 4 is fixedly connected to the top of the fixing plate 21. A second fixing rod 41 is fixedly connected to the left side of the support frame 4. By arranging the fixing piece 43, specifically, by starting the motor 3, the first rotating block 32 drives the mixing barrel 341 to rotate. At the same time, due to the several fixing pieces 43 and mixing blades 44 arranged inside it, the materials inside can be mixed, and the device mixes the materials more evenly when mixing, eliminating the need for manual mixing and saving a large amount of time and labor.

[0029] A pulley 42 is rotatably connected to the outer surface of the second fixing rod 41. The number of the second fixing rods 41 is two. The two second fixing rods 41 are symmetrically arranged with the mixing barrel 341 as the center. The number of the mixing blades 44 is several.

[0030] A second fixing block 5 is fixedly connected to the top of the fixing plate 21. A first rotating wheel 51 is rotatably connected to the left side of the second fixing block 5 through a pin shaft. A rotating groove is formed on the outer surface of the first rotating wheel 51. The inner wall of the rotating groove is in contact with the outer surface of the fixing ring 511. A limiting plate 52 is arranged on the right side of the second fixing block 5. A second rotating wheel 521 is rotatably connected to the right side of the limiting plate 52 through a pin shaft. The number of the limiting plates 52 is two. The two limiting plates 52 are symmetrically arranged with the second rotating wheel 521 as the center.

[0031] A specific application of this embodiment is as follows: By starting the motor 3, the rotating shaft 31 drives the first rotating block 32 to rotate. At the same time, due to the arrangement of the transmission belt 33, the first rotating block 32 is connected to the second rotating block 34. The rotation of the first rotating block 32 can drive the second rotating block 34 to move synchronously. The rotation of the second rotating block 34 can make the mixing barrel 341 rotate simultaneously. Since several fixing pieces 43 and several mixing blades 44 are arranged inside the mixing barrel 341, the materials to be mixed are fully mixed inside it under the rotation of the mixing barrel 341. After the materials are mixed, the user pulls the pull rod 23 to adjust the angle of the fixing plate 21 under the restriction of the rotating block 2 and the first fixing rod 121. When the opening of the mixing barrel 341 faces downward, the materials will be poured out, facilitating the extraction of the materials, making the device more convenient to use, reducing the workload of the staff, and improving work efficiency. After pouring out the materials, the pull rod 23 is moved upward to make the limiting ring 221 at the bottom of the fixing plate 21 contact the support rod 11, playing a supporting role and making the mixing barrel 341 more stable when mixing. The setting of the support leg 1 makes the overall operation of the device more stable, reduces large vibrations during operation, and makes the device safer to use. The setting of the first rotating wheel 51 and the fixing ring 511 restricts the rotation of the mixing barrel 341, preventing the potential risk of dislocation during rotation. The setting of several pulleys 42 makes the rotation of the mixing barrel 341 smoother.
