[0002] Soil disinfection in greenhouse horticulture is an important method for controlling soil-borne diseases and pests in horticultural crops. Currently, microwave disinfection systems for greenhouse horticulture soil mainly employ methods such as chemical fumigation, flame disinfection, and microwave irradiation. Among these, microwave soil disinfection is considered a green and pollution-free physical disinfection method. However, microwave soil disinfection still faces technical challenges such as irradiation leakage, uneven disinfection, and low efficiency. Therefore, designing a microwave disinfection system for greenhouse horticulture soil and its control methods is essential. Summary of the Invention

[0005] The tumbling microwave irradiation device includes a microwave sealed chamber located on top of the transport chassis, several microwave magnetrons located on both sides of the microwave sealed chamber, and a roller operation mechanism located inside the microwave sealed chamber.

[0006] The roller working mechanism includes a roller body located inside the microwave sealed chamber and having openings at both ends. The inner wall of the roller body is provided with several sets of toothed plates. A vibration frame is suspended and runs through the inside of the roller body, and a pushing component is provided on the vibration frame.

[0007] The pushing assembly includes several guide plates hinged to the inner side of the vibration frame via a fixed rotating shaft. A bogie is arranged parallel above the vibration frame. The several guide plates are hinged to the bogie via a movable rotating shaft. One end of the vibration frame is also provided with an adjustment mechanism for driving the bogie to move back and forth, thereby driving the several guide plates to rotate synchronously to the pushing guide position or the vertical guide position.

[0008] The microwave sealed chamber is provided with a tumbling mechanism outside to drive the main body of the drum to tumble, and the microwave sealed chamber is also provided with a vibration mechanism outside to drive the vibration frame to vibrate.

[0009] When the soil to be disinfected is transported into the drum body, the adjusting mechanism drives several guide plates to rotate synchronously to the pushing guide position, and the tumbling mechanism drives the drum body to tumble, so that the soil is gradually pushed to the outlet end of the drum body. Then the adjusting mechanism drives several guide plates to rotate synchronously to the vertical guide position. After disinfection is completed, the adjusting mechanism drives several guide plates to rotate synchronously to the pushing guide position. During the tumbling process of the drum body, the soil is gradually pushed out from the outlet end of the drum body.

[0010] In a further embodiment, the adjustment mechanism includes a steering drive located at one end of the vibration frame, the output end of which is hinged to one end of the bogie via a telescopic link.

[0011] In a further embodiment, the vibration mechanism includes support frames located at both ends of the microwave sealed chamber, an electromagnetic excitation driver is mounted on the top of the support frame, and the output end of the electromagnetic excitation driver is connected to the vibration frame.

[0012] In a further embodiment, the tumbling mechanism includes tumbling drivers located at the four corners of the outer side of the drum body. The output end of the tumbling driver is connected to a rolling gear, and both ends of the drum body are provided with outer circular hobbing teeth that mesh with the rolling gear.

[0014] In a further embodiment, the shoveling device includes a shoveling plate inclinedly disposed at the front end of the transport chassis, and retaining plates are provided on both sides of the shoveling plate.

[0015] In a further embodiment, the conveying device includes a conveyor frame fixed on the transport chassis and located between the shovel plate and the microwave sealed chamber, with a conveyor belt driven onto the conveyor frame, and the feed end of the conveyor belt located under the shovel plate.

[0016] In a further embodiment, an input hopper is provided on the front side of the microwave sealed chamber, the upper opening of the input hopper is located below the discharge end of the rear end of the conveyor belt, and the lower opening of the input hopper extends inward to the inlet end of the drum body. An discharge hopper is provided on the rear side of the microwave sealed chamber, the upper opening of the discharge hopper is located below the outlet end of the drum body, and the lower opening of the discharge hopper extends outward to the rear side of the transport chassis.

[0017] The control method for microwave disinfection of soil in protected horticulture includes the following steps:

[0018] S1. Turn on the microwave magnetron to create a microwave resonant field inside the microwave sealed chamber, which drives the drum body to tumble through the tumbling mechanism;

[0019] S2. The machine is driven forward by the cooperation of the transport chassis and power system. It performs soil removal operation through the soil shoveling device. The conveying device conveys the soil to be disinfected to the inlet end of the drum body. The bogie is driven to move through the adjustment mechanism, so that several guide plates rotate synchronously and tilt forward to the pushing guide position, forming a backward pushing guide shape. During the rolling movement of the drum body, the soil to be disinfected is gradually pushed towards the outlet end of the drum body and spread evenly inside the drum body.

[0020] S3. When the first batch of soil to be disinfected enters the drum body and is pushed from the inlet end to the outlet end of the drum body, the machine stops moving and begins to stand still. The bogie is driven to move by the adjustment mechanism, so that several guide plates rotate synchronously to the vertical guide position, forming a downward vertical guide shape. The soil to be disinfected moves downward along the radial turning trajectory of the drum body during the tumbling movement of the drum body, and the soil to be disinfected is continuously turned and stirred.

[0021] S4. After the last microwave irradiation of the soil reaches the ideal disinfection effect, the machine continues to move forward. The adjustment mechanism drives the bogie to move, so that several guide plates rotate synchronously and tilt forward to the pushing guide position, forming a backward pushing guide shape. The disinfected soil moves backward during the rolling and falling of the drum body and is discharged from the outlet end of the drum body to the facility horticulture site.

[0022] S5. The machine scoops up a new batch of soil to be disinfected and transfers it to the main body of the drum, starting the next round of soil microwave disinfection. The machine moves and stops intermittently, repeating this cycle to disinfect each piece of soil in the facility horticulture area with microwave irradiation.

[0023] In a further embodiment, in step S4, the single soil microwave irradiation time to achieve the ideal disinfection effect is 5 minutes.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention drives the bogie to move back and forth through the adjustment mechanism, thereby driving several guide plates to rotate synchronously to the pushing guide position or the vertical guide position. In conjunction with the tumbling drum body, the soil to be disinfected is evenly spread in the drum body. By continuously tumbling and stirring the soil to be disinfected, the tumbling microwave irradiation device continuously irradiates the facility horticulture soil in the microwave sealed chamber, thereby greatly improving the efficiency and uniformity of soil microwave disinfection, and realizing the microwave irradiation disinfection treatment of facility horticulture soil piece by piece.

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0031] Please see Figures 1-4 The present invention provides a technical solution: a microwave disinfection system for facility horticulture soil, including a transport chassis 1, a power system 2, a tumbling microwave irradiation device 3, a soil shoveling device 4, and a conveying device 5. The power system 2 and the tumbling microwave irradiation device 3 are installed sequentially on the top of the transport chassis 1, the soil shoveling device 4 is installed at the front end of the transport chassis 1, and the conveying device 5 is used to receive the soil to be disinfected shoveled by the soil shoveling device 4 and transfer the soil to the tumbling microwave irradiation device 3.

[0032] The tumbling microwave irradiation device 3 includes a microwave sealed chamber 6 located on top of the transport chassis 1, several microwave magnetrons 8 located on both sides of the microwave sealed chamber 6, and a roller operation mechanism 7 located inside the microwave sealed chamber 6. The microwave sealed chamber 6 is a metal sealed rectangular box. The resonant microwave field is formed inside the microwave sealed chamber 6 by utilizing the metal chamber sealing effect and microwave reflection effect, thereby improving the microwave effective utilization rate of the operation system. The main body of the roller operation mechanism 7 is made of microwave-penetrable materials such as plastic and ceramics to ensure that the soil to be disinfected inside the roller operation mechanism 7 can be fully irradiated and heated for disinfection.

[0033] The drum operation mechanism 7 includes a drum body 11 located inside the microwave sealed chamber 6 and having openings at both ends. The inner wall of the drum body 11 is provided with several sets of toothed plates 14. A vibration frame 17 is suspended and passes through the inside of the drum body 11. A pushing component is provided on the vibration frame 17.

[0034] The pushing assembly includes several guide plates 18 hinged to the inside of the vibration frame 17 via a fixed rotating shaft 20. A bogie 19 is arranged parallel above the vibration frame 17. The several guide plates 18 are hinged to the bogie 19 via a movable rotating shaft 21. One end of the vibration frame 17 is also provided with an adjustment mechanism for driving the bogie 19 to move back and forth, thereby driving the several guide plates 18 to rotate synchronously to the pushing guide position or the vertical guide position.

[0035] The microwave sealed chamber 6 is provided with a tumbling mechanism for driving the main body of the roller 11 to tumble, and the microwave sealed chamber 6 is also provided with a vibration mechanism for driving the vibration frame 17 to vibrate.

[0036] When the soil to be disinfected is transported into the drum body 11, the adjusting mechanism drives several guide plates 18 to rotate synchronously to the pushing guide position, and the tumbling mechanism drives the drum body 11 to tumble, so that the soil is gradually pushed to the outlet end of the drum body 11. Then the adjusting mechanism drives several guide plates 18 to rotate synchronously to the vertical guide position. After disinfection is completed, the adjusting mechanism drives several guide plates 18 to rotate synchronously to the pushing guide position. During the tumbling process of the drum body 11, the soil is gradually pushed out from the outlet end of the drum body 11.

[0037] In a further embodiment, the adjustment mechanism includes a steering drive 22 located at one end of the vibration frame 17, and the output end of the steering drive 22 is hinged to one end of the bogie 19 via a telescopic link 23.

[0038] Through the above technical solution, the steering drive 22 drives the telescopic link 23 to move, thereby pulling the bogie 19 to move back and forth. The bogie 19 drives several guide plates 18 to rotate around the fixed shaft 20 on the vibrating frame 17 through the moving shaft 21. When the bogie 19 moves forward, that is, moves towards the outlet end of the drum body 11, the inclined surfaces of several guide plates 18 are arranged in sequence to form a backward pushing guide shape. When the bogie 19 moves backward, that is, moves towards the inlet end of the drum body 11, several guide plates 18 rotate to the vertical direction, and the vertical surfaces of several guide plates 18 are arranged in sequence to form a downward vertical guide shape. When the steering drive 22 rotates in the forward direction, the bogie 19 moves towards the outlet end of the drum body 11. When the steering drive 22 rotates in the reverse direction, the bogie 19 moves towards the inlet end of the drum body 11.

[0039] In a further embodiment, the vibration mechanism includes support frames 15 located at both ends of the microwave sealed chamber 6, an electromagnetic excitation driver 16 mounted on the top of the support frame 15, and the output end of the electromagnetic excitation driver 16 connected to the vibration frame 17.

[0040] Through the above technical solution, the electromagnetic excitation driver 16 drives the vibration frame 17 to vibrate at high frequency, thereby ensuring that the soil can slide smoothly when it rolls down and passes through the guide plate 18.

[0041] In a further embodiment, the tumbling mechanism includes tumbling drivers 12 located at the four corners of the outer side of the roller body 11. The output end of the tumbling driver 12 is connected to the rolling gear 13. Both ends of the roller body 11 are provided with outer circular hobbing teeth 24 that mesh with the rolling gear 13.

[0042] Through the above technical solution, the tumbling driver 12 drives the rolling gear 13 to rotate, and then drives the drum body 11 to tumble through the outer circular hobbing gear 24, wherein the tumbling driver 12 is a tumbling motor.

[0043] In a further embodiment, each set of toothed plates 14 is arranged sequentially at intervals along the axial direction of the roller body 11, and the sets of toothed plates 14 are staggered along the circumferential direction of the roller body 11.

[0044] Through the above technical solution, the toothed plate 14 ensures that the soil inside the drum body 11 is fully tumbled and stirred when the drum body 11 is tumbling.

[0045] In a further embodiment, the shoveling device 4 includes a shoveling plate that is inclinedly disposed at the front end of the transport chassis 1, and retaining plates are provided on both sides of the shoveling plate.

[0046] The above technical solution, through the combination of shovel and retaining plates, enables the machine to shovel up the soil in the facility horticulture area as it moves forward.

[0047] In a further embodiment, the conveying device 5 includes a conveyor frame fixed on the transport chassis 1 and located between the shovel plate and the microwave sealed chamber 6. A conveyor belt is driven and connected to the conveyor frame, and the feed end of the conveyor belt is located under the shovel plate.

[0048] The above technical solution uses a conveyor belt to transport the soil from the shovel to the input hopper 9.

[0049] In a further embodiment, an input hopper 9 is provided on the front side of the microwave sealed chamber 6. The upper opening of the input hopper 9 is located below the discharge end of the rear end of the conveyor belt, and the lower opening of the input hopper 9 extends inward to the inlet end of the drum body 11. A discharge hopper 10 is provided on the rear side of the microwave sealed chamber 6. The upper opening of the discharge hopper 10 is located below the outlet end of the drum body 11, and the lower opening of the discharge hopper 10 extends outward to the rear side of the transport chassis 1.

[0050] Through the above technical solution, the soil conveyed by the conveyor belt is received by the input hopper 9 and guided to the inlet end of the roller body 11. The soil discharged after disinfection in the roller body 11 is received by the discharge hopper 10 and guided to the facility horticulture site.

[0051] The control method for microwave disinfection of soil in protected horticulture includes the following steps:

[0052] S1. Turn on the microwave magnetron 8 to create a microwave resonant field inside the microwave sealed chamber 6, and drive the drum body 11 to tumble through the tumbling mechanism;

[0053] S2. The machine is driven forward by the cooperation of the transport chassis 1 and the power system 2. The soil is removed by the soil shoveling device 4. The conveying device 5 conveys the soil to be disinfected to the inlet end of the drum body 11. The bogie 19 is driven to move by the adjustment mechanism, so that several guide plates 18 rotate synchronously and tilt forward to the pushing guide position, forming a backward pushing guide shape. During the rolling movement and falling of the drum body 11, the soil to be disinfected is gradually pushed towards the outlet end of the drum body 11 and spread evenly inside the drum body 11.

[0054] S3. When the first batch of soil to be disinfected enters the drum body 11 and is pushed from the inlet end to the outlet end of the drum body 11, the machine stops moving and begins to stand still. The bogie 19 is driven to move by the adjustment mechanism, so that several guide plates 18 rotate synchronously to the vertical guide position, forming a downward vertical guide shape. The soil to be disinfected moves downward along the radial turning trajectory of the drum body 11 during the tumbling motion of the drum body 11, and the soil to be disinfected is continuously turned and stirred.

[0055] S4. When the last microwave irradiation time of the soil reaches the ideal disinfection effect, the machine continues to move forward. The adjustment mechanism drives the bogie 19 to move, so that several guide plates 18 rotate synchronously and tilt forward to the pushing guide position, forming a backward pushing guide shape. The disinfected soil moves backward during the rolling motion of the drum body 11 and is discharged from the outlet end of the drum body 11 to the facility horticulture site.

[0056] S5. The machine scoops up a new batch of soil to be disinfected and transfers it to the drum body 11 to start the next round of soil microwave disinfection. The machine moves and stops intermittently, and the operation process is repeated in this cycle to disinfect the soil of the facility horticulture piece by piece with microwave irradiation.

[0057] In a further embodiment, in step S4, the single soil microwave irradiation time to achieve the ideal disinfection effect is 5 minutes.

[0058] Working principle: The microwave magnetron 8 is activated, creating a microwave resonant field inside the microwave sealed chamber 6. This field, driven by the tumbling driver 12, rotates the rolling gear 13, which in turn drives the drum body 11 to tumble via the outer hobbing gear 24. The implement is propelled forward by the cooperation of the transport chassis 1 and the power system 2. The shovel and retaining plates work together to scoop up the soil during the advance. The soil scooped by the shovel is transported by a conveyor belt to the input hopper 9 and falls into the inlet end of the drum body 11. The steering driver 22 drives the telescopic linkage 23, which in turn pulls the bogie 19 forward, towards the outlet end of the drum body 11. The bogie 19 drives several guide plates 18 to rotate around the fixed shaft 20 on the vibrating frame 17 via the moving shaft 21. This causes the guide plates 18 to rotate synchronously and tilt forward to the pushing guide position, forming a backward pushing guide shape. During the tumbling and falling motion of the drum body 11, the soil to be disinfected is gradually pushed towards the outlet end of the drum body 11 and evenly spread inside the drum body 11. When the first batch of soil to be disinfected enters the drum body 11 and is pushed from the inlet end to the outlet end, the machine stops moving and begins to stand still. The steering drive 22 drives the telescopic connecting rod 23 to move, thereby pulling the bogie 19 backward. The machine moves towards the inlet end of the drum body 11. The bogie 19 drives several guide plates 18 to rotate around the fixed shaft 20 on the vibrating frame 17 via the moving shaft 21, so that the guide plates 18 rotate synchronously to the vertical direction, forming a downward vertical guiding shape. The soil to be disinfected moves downward along the radial turning trajectory of the drum body 11 during the tumbling motion of the drum body 11, and the soil to be disinfected is continuously turned and stirred. When the previous microwave irradiation time of the soil reaches the ideal disinfection effect, the machine continues to move forward, and the telescopic connecting rod 23 is driven by the steering drive 22 to move, which in turn pulls the bogie 19 forward, that is, towards the drum body 11. 1. The outlet end moves, and the bogie 19 drives several guide plates 18 to rotate around the fixed shaft 20 on the vibrating frame 17 through the moving shaft 21. This causes the guide plates 18 to rotate synchronously and tilt forward to the pushing guide position, forming a backward pushing guide shape. The disinfected soil moves backward during the tumbling and falling of the drum body 11 and is discharged from the outlet end of the drum body 11 to the facility horticulture site. The machine scoops up a new round of soil to be disinfected and conveys it to the drum body 11 to start the next round of soil microwave disinfection operation. The machine moves and stops intermittently, and the operation process is repeated in this cycle to carry out microwave irradiation disinfection treatment on the soil of the facility horticulture site piece by piece.

However, the present invention is not limited to the specific details in the above embodiments.
