[0002] Radioactive soil refers to soil that has radioactive contamination characteristics because the content of radioactive substances in the soil exceeds normal levels. Radioactive substances can accumulate in the soil and enter the human body through the food chain, causing internal radiation damage. Victims may experience symptoms such as dizziness, fatigue, hair loss, and a decrease or increase in white blood cells.

[0003] Chemical amendments are commonly used agents for radioactive soil remediation, including lime, alkaline phosphate, iron oxide, carbonate and sulfide, etc. These amendments can react chemically with radioactive substances in the soil to form insoluble compounds, thereby reducing their migration ability and bioavailability.

[0052] See also Figure 1-12The present invention provides a technical solution: a device for dispensing an amending agent for radioactive soil remediation, comprising a reagent tube 1 in a horizontal state for containing an amending agent and a rotating rod 2 for tilling the soil and dispensing the amending agent, wherein the rotating rod 2 is a hollow structure with openings at both ends;

[0053] One end of the rotating rod 2 is rotatably connected to the medicine tube 1 with the axis of the medicine tube 1 as the center, and the interior of the rotating rod 2 is connected to the interior of the medicine tube 1, and the other end of the rotating rod 2 extends in the radial direction of the medicine tube 1 away from the medicine tube 1;

[0054] A driving part for driving the rotating rod 2 to rotate around the medicine tube 1 is provided between the rotating rod 2 and the medicine tube 1 .

[0055] In this scheme: the improver is placed in the medicine tube 1, the rotating rod 2 is rotatably connected and communicated with the medicine tube 1, and the driving part drives the rotating rod 2 to rotate around the medicine tube 1. When the rotating rod 2 moves to the bottom of the medicine tube 1, the improver enters the rotating rod 2 under the action of gravity, and slides downward along the inner wall of the rotating rod 2 and falls on the soil surface, so as to achieve the purpose of adding the improver.

[0056] At the same time, the rotating rod 2 is inserted into the soil during the rotation process, squeezing and pushing the soil, so as to achieve the purpose of tilling the soil, making the soil loose, so as to mix the improver entering the soil with the soil. That is, the device performs the work of adding the improver and the work of mixing the improver and the soil simultaneously, shortening the labor time and improving the work efficiency of adding the improver to the soil.

[0057] A feed hole 12 is provided at the top of the outer circumference of the reagent tube 1 , and both ends of the reagent tube 1 are closed to limit the loss of the improver from moving out of the two ends of the reagent tube 1 .

[0058] In this embodiment: a sliding bar 3 for covering the opening of the rotating rod 2 is provided at one end of the rotating rod 2 facing away from the medicine tube 1, and the sliding bar 3 is slidably connected to the rotating rod 2, and the sliding direction is parallel to the plane of the rotating track of the rotating rod 2 on the medicine tube 1;

[0059] An adjusting portion is provided between the slide bar 3 and the rotating rod 2 to drive the slide bar 3 to slide open or cover the opening of the rotating rod 2 .

[0060] In this solution, the end of the slide bar 3 facing the rotation direction of the rotating rod 2 is sharp, which improves the penetration of the slide bar 3, so that the slide bar 3 can be inserted into the soil to promote the tillage of the soil. The slide bar 3 is driven to slide on the rotating rod 2 by the adjustment part to open or cover the opening of the rotating rod 2 to control the release of the improver. When the end of the rotating rod 2 facing away from the drug tube 1 is close to the soil, the opening of the rotating rod 2 is opened to make the improver fall into the target soil release area, so as to control the release amount of the improver in the target area and reduce the waste of the improver.

[0061] In this embodiment: the slide bar 3 is perpendicular to the rotating rod 2, and the middle part of the slide bar 3 is serially connected to the rotating rod 2 and slides together;

[0062] The slide bar 3 is provided with a strip hole 31 extending in the length direction of the slide bar 3 on a plane facing the medicine tube 1, and the movement trajectory of the strip hole 31 passes through the opening position of the rotating rod 2;

[0063] The adjusting part comprises an elastic support member, one end of which is fixedly connected to one end of the slide bar 3 and the other end of which is fixedly connected to the rotating rod 2 . When the elastic support member is in a naturally extended state, the slide bar 3 covers the opening of the rotating rod 2 .

[0064] In this solution: the elastic support member is a compression spring 32, and the side wall of the slide bar 3 is provided with a mounting groove 34 extending in the length direction of the slide bar 3. The compression spring 32 is embedded in the mounting groove 34, and one end is fixedly connected to a plane of the mounting groove 34 facing the sharp end of the slide bar 3, and the other end is fixedly connected to the rotating rod 2, so that the slide bar 3 is flexibly supported by the compression spring 32.

[0065] During use, when the rotating rod 2 drives the slide bar 3 to rotate forwardly, the sharp end of the slide bar 3 is inserted into the soil, squeezing and pushing the soil to perform soil plowing; at the same time, under the resistance of the soil, the slide bar 3 slides on the rotating rod 2, and the compression spring 32 is squeezed and contracted, so that the strip hole 31 moves close to the opening of the rotating rod 2 at the end facing away from the medicine tube 1, until the strip hole 31 overlaps and is connected with the opening of the rotating rod 2, forming a channel for the improvement agent in the rotating rod 2 to move out, so that the improvement agent is moved out and placed in the soil.

[0066] The rotating rod 2 drives the slide bar 3 to continue to rotate forward. When the slide bar 3 is out of contact with the soil, the resistance of the soil to the slide bar 3 disappears, and the compression spring 32 releases energy to stretch freely, pushing the slide bar 3 back to the initial position. The strip hole 31 is away from the opening of the rotating rod 2, so that the strip hole 31 is misaligned with the opening of the rotating rod 2, blocking the channel for the improver in the rotating rod 2 to move out, so that the improver can be stably stored in the soil, reducing the risk of the improver scattering freely, so as to control the amount of improver put into the soil.

[0067] That is, when the slide bar 3 is plowing the soil, the channel for moving the improver out of the rotating rod 2 is automatically opened, and the improver is automatically added into the soil; when the slide bar 3 is moved out of the soil to end the plowing work, the channel for moving the improver out of the rotating rod 2 is automatically blocked, so as to control the amount of improver added into the soil.

[0068] In this embodiment: the end of the rotating rod 2 facing away from the medicine tube 1 is connected to a rotating ring 4 coaxial with the rotating rod 2, and the end of the rotating ring 4 facing away from the rotating rod 2 is fixedly connected to a plurality of baffles 41, and the plurality of baffles 41 are evenly arranged around the circumference of the rotating ring 4;

[0069] The baffles 41 have an edge facing the axis of the swivel 4 and converge and intersect at the center of the swivel 4 , and an edge facing away from the axis of the swivel 4 extends radially to the outside of the outer circumference of the swivel 4 , and the angle between the baffles 41 and the end face of the swivel 4 is acute.

[0070] In this embodiment: the end of the swivel 4 facing away from the baffle 41 is inserted into the opening of the rotating rod 2 and rotates coaxially. A linkage component is provided between the swivel 4 and the slide bar 3. When the slide bar 3 slides on the rotating rod 2, the swivel 4 is driven to rotate on the rotating rod 2 through the linkage component.

[0071] In this solution: multiple baffles 41 cover the opening of the rotating rod 2 facing away from the medicine tube 1, but the improver can pass through the gap between two adjacent baffles 41; the swivel 4 and the multiple baffles 41 form a screen structure, and the gap between two adjacent baffles 41 is the sieve hole in the screen structure, which can refine and screen the improver removed from the rotating rod 2 to facilitate mixing of the improver with the soil.

[0072] During use, when the slide bar 3 slides on the rotating rod 2, the swivel 4 is driven to rotate on the rotating rod 2 through the linkage assembly, and the swivel 4 drives the baffle 41 to rotate at the open end of the rotating rod 2. When the improver in the rotating rod 2 is moved out, it falls into the gap between two adjacent baffles 41, so that the baffle 41 beats the refined improver, and applies a thrust to the improver along the tangential direction of the circumference of the swivel 4, so that the improver is rotated and thrown out, thereby expanding the coverage area of ​​the improver, and further facilitating the mixing of the improver and the soil.

[0073] In this embodiment: the inner surface of the rotating rod 2 facing away from the medicine tube 1 is provided with a groove 21, the linkage assembly comprises a rack 33 parallel to the slide bar 3 and a rotating shaft 24 parallel to the rotating rod 2, and the rack 33 is fixedly connected to a side surface of the slide bar 3;

[0074] The rotating shaft 24 is serially connected to the side wall of the rotating rod 2 and rotates with the rotating rod 2. One end of the rotating shaft 24 is located in the groove 21 and is coaxially fixedly connected to a first gear 25 meshing with the rack 33. The other end of the rotating shaft 24 is located outside the end of the rotating rod 2 facing away from the medicine tube 1 and is coaxially fixedly connected to a second gear 26.

[0075] An outer gear ring 42 meshing with the second gear 26 is coaxially fixedly connected to the outer end of the rotating ring 4 facing away from the rotating rod 2 .

[0076] In this solution, the opening of the rotating rod 2 at the end facing away from the medicine tube 1 is smaller than the length of the strip hole 31. The rack 33, the first gear 25, the second gear 26, the rotating shaft 24 and the outer gear ring 42 are spliced ​​to form a linkage assembly, and the sliding of the slide bar 3 on the rotating rod 2 is linked to the rotation of the rotating ring 4.

[0077] During use, when the sharp end of the slide bar 3 is inserted into the soil, the rotating rod 2 drives the slide bar 3 to work together to plow the soil. Under the obstruction of the soil, the slide bar 3 drives the rack 33 to slide forward on the rotating rod 2. The rack 33 drives the first gear 25, the rotating shaft 24 and the second gear 26 to rotate forward together. The second gear 26 drives the outer gear ring 42 to rotate forward, so that the rotating ring 4 drives the baffle 41 to rotate forward together, and the baffle 41 beats and crushes the soil, so as to further work on plowing the soil.

[0078] When the end of the strip hole 31 facing away from the sharp end of the slide bar 3 is connected to the opening of the rotating rod 2, the channel for the modifier to be removed from the rotating rod 2 is opened, and the modifier is automatically added. The slide bar 3 continues to slide forward on the rotating rod 2, and the strip hole 31 remains connected to the opening of the rotating rod 2, and the modifier is continuously added. At the same time, the linkage assembly drives the swivel 4 and the baffle 41 to rotate forward, and the baffle 41 rotates and throws the modifier to expand the coverage area of ​​the modifier, and the baffle 41 mixes the modifier with the soil.

[0079] That is, when the strip hole 31 is connected to the opening of the rotating rod 2, when the slide bar 3 slides on the rotating rod 2, the improver is automatically added into the soil, and the baffle 41 rotates to beat and crush the soil, and at the same time, the improver and the soil are stirred and mixed.

[0080] In this embodiment: a discharge hole 11 is opened at the bottom of the outer circumferential surface of the medicine tube 1, a collar 22 for covering the discharge hole 11 is fixedly connected to one end of the rotating rod 2, and the interior of the rotating rod 2 is connected to the interior of the collar 22;

[0081] The collar 22 is sleeved on the outside of the medicine tube 1 , and the collar 22 and the medicine tube 1 are rotatably matched.

[0082] In this solution: the discharge hole 11 is arranged at the bottom of the medicine tube 1. When the rotating rod 2 rotates to the top of the medicine tube 1, the collar 22 covers the discharge hole 11, blocks the movement channel of the improver between the medicine tube 1 and the rotating rod 2, and restricts the improver in the rotating rod 2 from flowing back into the medicine tube 1; when the rotating rod 2 rotates to the bottom of the medicine tube 1, the opening at one end of the rotating rod 2 facing the medicine tube 1 overlaps and links with the discharge hole 11, opens the movement channel of the improver between the medicine tube 1 and the rotating rod 2, so that the improver in the medicine tube 1 can enter the rotating rod 2, and the improver can be continuously replenished into the rotating rod 2.

[0083] In this embodiment: a plurality of rotating rods 2 are provided, and the plurality of rotating rods 2 are sequentially arranged along the axial direction of the medicine tube 1;

[0084] There are multiple discharge holes 11 , and the multiple discharge holes 11 are arranged in one-to-one correspondence with the multiple rotating rods 2 .

[0085] In this solution: a rotating rod 2 is used as a working unit, and the working unit is used to till the soil and add the improver. By arranging multiple working units on the drug tube 1, multiple working units are used to simultaneously till the soil and add the improver, thereby improving work efficiency.

[0086] In this embodiment: a support bar 5 parallel to the medicine tube 1 is provided on one side of the medicine tube 1, and a plurality of connecting rods 6 corresponding to the plurality of collars 22 are provided on the support bar 5;

[0087] The connecting rod 6 is perpendicular to the medicine tube 1, one end of the connecting rod 6 is inserted into the support bar 5 and rotated together, and the other end is inserted into the side wall of the medicine tube 1 and rotated together;

[0088] The driving part includes a motor 7 fixedly mounted on the support bar 5 and a plurality of bevel gear rings 23 corresponding to the plurality of collars 22 one by one, and the bevel gear rings 23 are coaxially fixedly connected to one end surface of the corresponding collar 22;

[0089] The end of the connecting rod 6 facing the medicine tube 1 is coaxially fixedly connected with a bevel gear 61 meshing with the corresponding bevel gear ring 23 , and the ends of the connecting rods 6 facing away from the medicine tube 1 are all transmission-connected to the output end of the motor 7 .

[0090] In this embodiment: the ends of the plurality of connecting rods 6 facing away from the medicine tube 1 are coaxially fixedly connected with a driven sprocket 62, the output end of the motor 7 is fixedly connected with a driving sprocket 71, and the driving sprocket 71 and the plurality of driven sprockets 62 are meshed with a chain 8 installed externally.

[0091] In this solution: a sleeve 51 is disposed on the outer surface of the connecting rod 6 and rotatably cooperates with it. One end of the sleeve 51 is fixedly connected to the medicine tube 1, and the other end is fixedly connected to the support bar 5. The medicine tube 1 and the support bar 5 are connected and fixed into a whole through the sleeve 51, thereby improving the stability of the connection between the connecting rod 6, the medicine tube 1 and the support bar 5.

[0092] During use, the support bar 5 is fixedly mounted on a tractor or other tractor, and the tractor provides traction to the device. The motor 7 is started, and the motor 7 drives the driving sprocket 71 to rotate forward. The driving sprocket 71 drives multiple driven sprockets 62 to rotate synchronously in the same direction and at the same speed through the chain 8, so that the connecting rod 6 drives the bevel gear 61 to rotate forward together, and the bevel gear 61 drives the corresponding bevel gear ring 23 to rotate forward, so that the corresponding rotating rod 2 rotates forward to perform the work of tilling the soil and placing the improver. That is, when the motor 7 is started, the multiple rotating rods 2 synchronously perform the work of tilling the soil and placing the improver.

[0093] Among them, the specific model of motor 7 is Demark 180M-35015E-E.
