[0001] This invention relates to the field of soil disinfection technology, specifically to a soil microwave uniform disinfection system and its operation method. Background Technology

[0002] Microwave disinfection of agricultural soil is an essential means of controlling soil-borne diseases and pests in the field. Currently, most agricultural soil microwave disinfection systems adopt open microwave irradiation, which leads to microwave irradiation leakage, reduces operational efficiency, and harms the health of workers. On the other hand, existing closed microwave irradiation systems have fixed application positions, which can easily cause localized high temperatures and uneven disinfection, failing to achieve good soil disinfection results. Therefore, it is necessary to design a uniform microwave disinfection system for soil and its operation method. Summary of the Invention

[0008] When the soil is conveyed into the cylindrical drum, the lateral push drive guide mechanism rotates to the lateral position, and the rolling drive mechanism drives the cylindrical drum to roll, so that the soil is gradually pushed and spread to the outlet end of the cylindrical drum. Then, the lateral push drive guide mechanism rotates to the middle position. After disinfection is completed, the lateral push drive guide mechanism rotates back to the lateral position. During the rolling of the cylindrical drum, the soil is gradually pushed and discharged from the outlet end of the cylindrical drum.

[0009] In a further embodiment, the guiding mechanism includes a guide block disposed on the inner wall of the cylindrical roller, a rotating shaft fixed at the bottom of the guide block, a steering rod fixed at one end of the rotating shaft, the end of the steering rod passing through the cylindrical roller and hinged to the adjacent transverse push rod, a guide groove being provided in the guide block, and sliding pieces slidingly engaged at both ends of the guide groove, with a sliding shaft fixed at the bottom of each of the two sliding pieces.

[0010] In a further embodiment, the inner wall of the cylindrical roller is provided with a plurality of shaft holes that cooperate with the rotating shaft, and the inner wall of the cylindrical roller is provided with arc-shaped sliding grooves on both sides of each shaft hole, and the sliding shaft is slidably engaged with the arc-shaped sliding grooves.

[0011] In a further embodiment, the rolling drive mechanism includes a rolling motor disposed outside the microwave resonant cavity and located on both sides of the microwave resonant cavity. The output end of the rolling motor is connected to a rolling gear. The cylindrical roller is provided with annular teeth at both ends of the circumference, and the annular teeth mesh with the adjacent rolling gear.

[0012] In a further embodiment, the lateral push drive includes a lateral push cylinder disposed outside the microwave resonant cavity and located on both sides of the microwave resonant cavity. The output end of the lateral push cylinder is connected to a lateral push block, and the lateral push block is provided with a lateral push groove that slides and engages with the adjacent annular slide.

[0013] In a further embodiment, one end of the microwave resonant cavity is provided with a feed inlet, the feed inlet slide extends inward to the inlet end of the cylindrical roller, and the other end of the microwave resonant cavity is provided with a discharge inlet, the discharge inlet slide extends inward to the outlet end of the cylindrical roller.

[0014] In a further embodiment, the shoveling mechanism includes a bucket located at the front end of the power chassis, with connecting plates on both sides of the bucket. One end of the connecting plate is connected to a mounting frame, and the front end of the mounting frame is hinged to the mounting plate via a hinge rod. The bottom of the mounting plate is provided with height-adjustable casters.

[0015] In a further embodiment, the conveying mechanism includes a conveyor frame fixed to the front end of the power chassis, a conveyor belt driven to the conveyor frame, the feed end of the conveyor belt being located below the rear end of the bucket, and the discharge end of the conveyor belt being located above the feed inlet.

[0016] A method for uniform microwave disinfection of soil includes the following steps:

[0017] S1. The power chassis drives the entire machine into the designated position, turns on the microwave generating unit, so that a microwave irradiation field is formed in the microwave resonant cavity, and the rolling drive mechanism works to drive the cylindrical drum to roll.

[0018] S2. The power chassis drives the machine to move as a whole. The soil is shoveled by the soil shovel mechanism. The conveying mechanism transports the soil to be disinfected shoveled by the soil shovel mechanism to the inlet end of the cylindrical drum. The guide mechanism is driven to rotate to the side position by the horizontal push drive to form a spiral guide structure. During the rotation of the cylindrical drum, the soil to be disinfected is gradually pushed and spread until it reaches the outlet end of the cylindrical drum.

[0019] S3. The guide mechanism is rotated to the middle position by the horizontal push drive to form a planar guide structure. The axial distribution of the soil to be disinfected remains unchanged. The cylindrical roller rolls, so that the soil to be disinfected continues to roll. It is continuously disinfected by the microwave irradiation field until the disinfection effect is achieved.

[0020] S4. The guide mechanism is rotated to the lateral position by the horizontal push drive to form a spiral guide structure. During the rolling of the cylindrical drum, the disinfected soil is gradually pushed and discharged from the outlet end of the cylindrical drum.

[0022] In a further embodiment, in step S3, during the continuous disinfection treatment of the microwave irradiation field, the soil irradiation time for a single session is 5-10 minutes.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention uses a rolling microwave irradiation system to efficiently disinfect field soil, effectively reducing the risk of local overheating of microwave irradiation. By pushing the annular slide through the horizontal drive, the horizontal push rod moves laterally, thereby driving the guide mechanism to rotate to the lateral or central position. In conjunction with the rolling cylindrical drum, the soil to be disinfected is evenly spread in the cylindrical drum. By continuously rolling and stirring the soil to be disinfected, the efficiency and uniformity of soil microwave irradiation are effectively improved, realizing the microwave irradiation disinfection of field soil piece by piece.

[0033] 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.

[0034] Please see Figures 1-8 The present invention provides a technical solution: a soil microwave uniform disinfection operation system, including a power chassis 1, an on-board control box 2, a rolling microwave irradiation system 3, a conveying mechanism 4 and a soil shoveling mechanism 5. The soil shoveling mechanism 5 and the conveying mechanism 4 are installed in sequence at the front end of the power chassis 1, and the on-board control box 2 and the rolling microwave irradiation system 3 are installed at the upper end of the power chassis 1.

[0035] The rolling microwave irradiation system 3 includes a microwave resonant cavity 6 located on the upper end of the power chassis 1, microwave generating units 7 located on both sides of the microwave resonant cavity 6, and a roller mechanism located inside the microwave resonant cavity 6. The microwave resonant cavity 6 is made of metal and is a closed rectangle, used to constrain microwave irradiation, generate a resonant microwave field, reduce microwave leakage, and improve microwave efficiency. The components of the roller mechanism are made of microwave-penetrable materials such as plastic and ceramic to ensure that the soil to be disinfected inside the roller mechanism can be fully irradiated and disinfected.

[0036] The roller mechanism includes a cylindrical roller 10 with open ends inside the microwave resonant cavity 6. Both ends of the cylindrical roller 10 are provided with annular slides 15. Several transverse push rods 16 are fixedly connected between the two annular slides 15. Several guide mechanisms 17 that are hinged to the adjacent transverse push rods 16 are provided on the inner wall of the cylindrical roller 10 along the extension direction of the adjacent transverse push rods 16.

[0037] The microwave resonant cavity 6 is provided with a rolling drive mechanism for driving the cylindrical roller 10 to roll. The microwave resonant cavity 6 is also provided with a transverse push drive 11 for pushing the annular slide 15 to move the transverse push rod 16 laterally, thereby driving the guide mechanism 17 to rotate to the lateral or middle position.

[0038] When the soil is conveyed into the cylindrical roller 10, the lateral push drive 11 drives the guide mechanism 17 to rotate to the lateral position, and the rolling drive mechanism drives the cylindrical roller 10 to roll, so that the soil is gradually pushed and spread to the outlet end of the cylindrical roller 10. Then the lateral push drive 11 drives the guide mechanism 17 to rotate to the middle position. After the disinfection is completed, the lateral push drive 11 drives the guide mechanism 17 to rotate back to the lateral position. During the rolling of the cylindrical roller 10, the soil is gradually pushed and discharged from the outlet end of the cylindrical roller 10.

[0039] In a further embodiment, the guiding mechanism 17 includes a guide block 18 disposed on the inner wall of the cylindrical roller 10. A rotating shaft 22 is fixed at the bottom of the guide block 18. A steering rod 23 is fixed at one end of the rotating shaft 22. The end of the steering rod 23 passes through the cylindrical roller 10 and is hinged to the adjacent transverse push rod 16. A guide groove 19 is provided in the guide block 18. Sliding pieces 20 are slidably fitted at both ends of the guide groove 19. A sliding shaft 21 is fixed at the bottom of each of the two sliding pieces 20.

[0040] Through the above technical solution, the transverse push drive 11 on one side pushes the annular slide rail 15, causing the transverse push rod 16 to move laterally. At this time, the transverse push drive 11 on the other side does not obstruct the lateral movement of the transverse push rod 16. When the transverse push rod 16 moves laterally, one end of the steering rod 23 rotates relative to the adjacent transverse push rod 16 around the hinge point. The other end of the steering rod 23 drives the rotating shaft 22 to rotate synchronously, thereby driving the guide block 18 to rotate, and then driving the two sliding pieces 20 to rotate to the lateral position. When it is necessary to rotate the two sliding pieces 20 to the middle position, the transverse push drive 11 on the other side pushes the annular slide rail 15, causing the transverse push rod 16 to move laterally. Relatively speaking, at this time, the other transverse push drive 11 does not obstruct the lateral movement of the transverse push rod 16. When the transverse push rod 16 moves laterally, one end of the steering rod 23 rotates relative to the adjacent transverse push rod 16 around the hinge point. The other end of the steering rod 23 drives the rotating shaft 22 to rotate synchronously, thereby driving the guide block 18 to rotate, and then driving the two sliding pieces 20 to rotate to the middle position.

[0041] In a further embodiment, the inner wall of the cylindrical roller 10 is provided with a plurality of shaft holes 25 that cooperate with the rotating shaft 22. The inner wall of the cylindrical roller 10 is provided with arc-shaped grooves 24 on both sides of each shaft hole 25, and the sliding shaft 21 is slidably engaged with the arc-shaped grooves 24.

[0042] Through the above technical solution, the rotation of the rotating shaft 22 is facilitated by the setting of the rotating shaft hole 25, and the sliding shaft 21 slides in the arc-shaped sliding groove 24 during the rotation of the sliding piece 20. When the sliding piece 20 rotates to the lateral position, the sliding shaft 21 drives the sliding piece 20 to extend out of the guide groove 19, thereby increasing the overall guiding area of ​​the two sliding pieces 20. When the sliding piece 20 rotates to the middle position, the sliding shaft 21 drives the sliding piece 20 to retract into the guide groove 19 along the arc-shaped sliding groove 24, forming a flat guiding structure in the inner cavity of the cylindrical roller 10.

[0043] In a further embodiment, the rolling drive mechanism includes a rolling motor 12 disposed outside the microwave resonant cavity 6 and located on both sides of the microwave resonant cavity 6. The output end of the rolling motor 12 is connected to the rolling gear 13. The cylindrical roller 10 is provided with annular teeth 14 at both ends of the circumference, and the annular teeth 14 mesh with the adjacent rolling gear 13.

[0044] Through the above technical solution, the rolling motor 12 drives the rolling gear 13 to rotate, which in turn drives the cylindrical roller 10 to roll through the ring tooth 14.

[0045] In a further embodiment, the transverse push drive 11 includes a transverse push cylinder disposed outside the microwave resonant cavity 6 and located on both sides of the microwave resonant cavity 6. The output end of the transverse push cylinder is connected to the transverse push block, and the transverse push block is provided with a transverse push groove that slides in cooperation with the adjacent annular slide 15.

[0046] Through the above technical solution, the horizontal pusher cylinder pushes the horizontal pusher block to move, thereby pushing the annular slide 15. The horizontal pusher groove allows the annular slide 15 to slide within the horizontal pusher groove during the rotation of the cylindrical roller 10, facilitating the horizontal movement of the annular slide 15 and the transverse pusher 16 as a whole. The horizontal pusher cylinder on one side only provides thrust, not pull. While the horizontal pusher cylinder on one side pushes the annular slide 15 and the transverse pusher 16 to move as a whole, the horizontal pusher cylinder on the other side drives the horizontal pusher block to retract and supports the annular slide 15 through the horizontal pusher groove, without restricting the movement of the annular slide 15 and the transverse pusher 16 as a whole. The reciprocating motion of the annular slide 15 and the transverse pusher 16 as a whole is achieved through the cooperation of the horizontal pusher cylinders on both sides.

[0047] In a further embodiment, one end of the microwave resonant cavity 6 is provided with a feed inlet 8, the feed inlet 8 slide extends inward to the inlet end of the cylindrical roller 10, and the other end of the microwave resonant cavity 6 is provided with a discharge inlet 9, the discharge inlet 9 slide extends inward to the outlet end of the cylindrical roller 10.

[0048] Through the above technical solution, the soil conveyed by the conveying mechanism 4 is received by the inlet 8 and guided to the inlet end of the cylindrical drum 10. The soil discharged after disinfection in the cylindrical drum 10 is received by the outlet 9 and guided back to the farmland.

[0049] In a further embodiment, the shoveling mechanism 5 includes a bucket located at the front end of the power chassis 1. Connecting plates are provided on both sides of the bucket. One end of the connecting plate is connected to the mounting frame. The front end of the mounting frame is hinged to the mounting plate via a hinge rod. The bottom of the mounting plate is provided with height-adjustable casters.

[0050] The above technical solution controls the depth of the bucket cutting into the soil by adjusting the height of the moving wheels. By setting up the moving wheels, the sliding friction between the front end of the bucket and the soil is transformed into rolling friction of the moving wheels, thereby reducing the resistance when the bucket moves forward.

[0051] In a further embodiment, the conveying mechanism 4 includes a conveying frame fixed to the front end of the power chassis 1, a conveyor belt driven to the conveying frame, the feed end of the conveyor belt being located below the rear end of the bucket, and the discharge end of the conveyor belt being located above the feed inlet 8.

[0052] The above technical solution uses a conveyor belt to transport the soil scooped by the bucket to the feed inlet 8.

[0053] A method for uniform microwave disinfection of soil includes the following steps:

[0054] S1. The power chassis 1 drives the entire machine into the designated position, turns on the microwave generating unit 7, so that a microwave irradiation field is formed in the microwave resonant cavity 6, and the rolling drive mechanism works to drive the cylindrical roller 10 to roll.

[0055] S2. The power chassis 1 drives the machine to move as a whole, and the soil is shoveled by the soil shovel mechanism 5. The conveying mechanism 4 conveys the soil to be disinfected shoveled by the soil shovel mechanism 5 to the inlet end of the cylindrical drum 10. The guide mechanism 17 is driven to rotate to the side position by the horizontal push drive 11 to form a spiral guide structure. During the rolling process of the cylindrical drum 10, the soil to be disinfected is gradually pushed and spread until it reaches the outlet end of the cylindrical drum 10.

[0056] S3. The guide mechanism 17 is rotated to the middle position by the horizontal push drive 11 to form a planar guide structure. The axial distribution of the soil to be disinfected remains unchanged. The cylindrical roller 10 rolls, so that the soil to be disinfected continues to roll. It is continuously disinfected by the microwave irradiation field until the disinfection effect is achieved.

[0057] S4. The guide mechanism 17 is rotated to the lateral position by the horizontal push drive 11 to form a spiral guide structure. During the rolling process of the cylindrical drum 10, the disinfected soil is gradually pushed out from the outlet end of the cylindrical drum 10.

[0058] S5. Conduct a new round of soil microwave irradiation disinfection treatment.

[0059] In a further embodiment, in step S3, during the continuous disinfection treatment of the microwave irradiation field, the soil irradiation time for a single session is 5-10 minutes.

[0060] The above technical solution achieves ideal soil disinfection by using an appropriate single soil irradiation time.

[0061] Working Principle: After the machine enters the predetermined position in the field and begins operation, the microwave generating unit 7 is activated, forming a microwave irradiation field within the microwave resonant cavity 6. This controls the machine's forward movement, and the shoveling mechanism 5 performs shoveling operations. The conveying mechanism 4 transports the soil to be disinfected to the inlet end of the cylindrical drum 10. As the soil continuously enters the cylindrical drum 10, it undergoes continuous tumbling motion under the action of the rolling drive mechanism. Simultaneously, the lateral push drive 11 is adjusted, turning the guide mechanism 17 to a lateral position, forming a spiral guide structure within the cylindrical drum 10. The soil to be disinfected is pushed backward by axial thrust during the tumbling motion, gradually spreading evenly inside the cylindrical drum 10. When the first batch of soil to be disinfected enters the inner cavity of the cylindrical drum 10 and is pushed from the inlet end to the outlet end, the machine begins to pause. At the same time, the lateral push drive 11 is adjusted again, turning the guide mechanism 17 to a middle position, forming a horizontal guide structure within the inner cavity of the cylindrical drum 10. With a spiral guide structure, the soil to be disinfected no longer moves backward, and the axial distribution remains unchanged. The cylindrical drum 10 continuously rotates under the action of the rolling drive mechanism, generating a radial rotation force on the soil to be disinfected in the inner cavity of the cylindrical drum 10. This continuous rolling and stirring of the soil effectively improves the efficiency and uniformity of microwave irradiation of the soil. When the single soil irradiation time reaches the ideal disinfection effect, the machine begins to move forward. At the same time, the horizontal push drive 11 is adjusted again, and the guide mechanism 17 is rotated to the lateral position, forming a spiral guide structure in the inner cavity of the cylindrical drum 10. The disinfected soil is pushed backward by the axial pushing force while rotating and is discharged from the outlet end of the cylindrical drum 10. The disinfected soil is guided back to the farmland through the discharge inclined port 9. At the same time, the machine scoops up a new round of soil to be disinfected and conveys it into the cylindrical drum 10 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 in the field piece by piece with microwave irradiation.

[0062] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
