[0003] At present, the existing vegetable soil microwave treatment equipment mostly adopts a batch operation mode: a certain amount of soil is manually or mechanically put into the treatment cavity, and after disinfection and salt reduction, the whole is unloaded and enters the next treatment cycle. This mode has significant limitations: due to the intermittent operation of batch feeding and unloading, it cannot realize the continuous conveying and treatment of soil, resulting in limited processing capacity per unit time, which is difficult to meet the efficient production needs of large-scale vegetable planting. More importantly, during batch processing, the soil is prone to form a pile in the cavity, and the large pieces of soil are pressed against each other due to the lack of pretreatment crushing, making it difficult for microwave energy to penetrate to the center area of the pile, resulting in uneven heating of the soil in each layer - the outer layer of soil may lose organic matter due to excessive heating, and the inner layer of soil may not be able to completely kill pathogenic bacteria or remove salt due to insufficient energy, ultimately affecting the stability and consistency of the treatment effect.

The inner wall of the fixed bracket 1 is rotatably connected, and the outer wall of the microwave resonance cavity 11 is fixedly connected to a rack guide 16, and the rack guide 16 and the transmission gear 14 are meshed with each other; the feeding system 3 includes a feeding bracket 31 fixed to the side wall of the stable bracket 1, and the top of the feeding bracket 31 is fixedly connected to a mounting base 32, and the mounting base 32 is tilted upward. A conveyor belt 33 is installed on the inner wall of the mounting base 32, and a servo motor 34 is installed on the outer wall of the mounting base 32 for driving the conveyor belt 33 to move along the inner wall of the mounting base 32. The end of the conveyor belt 33 is located above the soil processing chamber 2, and a loading box 35 is fixedly connected to the bottom end of the mounting base 32; two mounting brackets 23 are fixedly connected to the outer wall of the soil processing chamber 2, and the mounting brackets 23 are fixedly connected to the stabilizing bracket 1. A guide plate 26 is fixedly connected to the top of the soil processing chamber 2, and the guide plate 26 is arranged in an inclined structure. The bottom of the sealed processing chamber 22 is provided with heat dissipation holes 28, and the top of the sealed processing chamber 22 is a sloped structure. A microwave generator is installed on the inner wall of the soil processing chamber 2 for microwave treatment of the soil;

[0034] It is necessary to install the stable bracket 1 in the designated working area, and then the majority of the soil to be processed can be transferred to the servo motor 34, and after the servo motor 34 switch is turned on, the moving conveyor belt 33 can transfer the soil in the loading box 35 to the soil processing bin 2 in turn, and at the same time, the falling soil can be guided by the guide plate 26 and moved into the soil processing bin 2, and the large pieces of soil can be cut into small pieces by the dynamic crushing unit 4. After the speed-changing motor 13 switch is turned on, the transmission gear 14 can be mobilized to rotate, so that the meshing main shaft drive shaft 15 can mobilize the microwave resonant cavity 11 to rotate slowly counterclockwise on the stable bracket 1. At the same time, the uppermost opening of the spiral spoiler 12 can be used with the sealed processing chamber 22 to transfer the soil in the soil processing bin 2 to the spiral spoiler 12 in turn, and place it in layers under the spiral characteristics of the spiral spoiler 12. When there is soil between the spiral spoiler 12 and the sealed processing chamber 22, that is, Under the action of the microwave generator in the sealed treatment chamber 22, the soil can be subjected to microwave treatment, and the effects of disinfection and salt reduction can be achieved. At the same time, the feeding speed of the soil in the spiral spoiler 12 and the duration of microwave treatment can be changed according to the rotation speed of the output shaft of the variable speed motor 13, and the material discharged from the bottom of the microwave resonant cavity 11 can be transferred to the next workstation with the external conveying device. This step cooperates with the stratification of the spiral spoiler 12 and the limiting effect of the sealed treatment chamber 22 to place the soil to be treated in equal thickness. At the same time, the sealed treatment chamber 22 can complete the continuous discharge of soil when it rotates continuously, solving the problem that the soil accumulation is large and the central soil is difficult to be processed, and achieving the uniformity of the temperature of each layer of the soil and the stable effect of disinfection and salt reduction of the soil. Under the action of the dynamic crushing unit 4, the gap between the soil and the soil can be increased to facilitate the conduction of microwaves, and the inclined guide plate 26 can guide the soil below for treatment.

[0035] according to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the dynamic crushing unit 4 includes a crushing unit frame 41 fixed to the outer wall of the microwave resonant cavity 11, a rotating shaft 42 is fixedly connected to the middle of the crushing unit frame 41, the rotating shaft 42 is rotatably connected to the sealed processing chamber 22, a connecting rod 43 is fixedly connected to the top of the rotating shaft 42, a support plate 44 is fixedly connected to the top of the connecting rod 43, and two alloy breaking knives 45 are fixed to the bottom of the support plate 44 by bolts, which are used to cut large pieces of soil in the soil processing chamber 2; the silo support bases 21 are multiple and arranged in a circular array, and several of the silo support bases 21 are inclined structures, and the ends of the silo support bases 21 are fixedly connected to reinforcement rib rings 27, and the reinforcement rib rings 27 are fixedly connected to the inner wall of the soil processing chamber 2;

[0036] When it is necessary to cut large pieces of soil in the soil processing bin 2, the microwave resonant cavity 11 can rotate as a whole, and at the same time, under the action of the rotating shaft 42, it can drive the two alloy breaker knives 45 to rotate, and the bin support base 21 is set in several ways, so that equidistant gaps can be generated between adjacent bin support bases 21, so that large pieces of soil can be supported. At the same time, the alloy breaker knives 45 can be discharged from the gaps after shearing. When the alloy breaker knives 45 that have been used for a long time need to be maintained later, the bolts can be unscrewed with the help of tools, and the alloy breaker knives 45 can be disassembled. This step, in conjunction with the set alloy breaker knives 45, can realize the shearing of large pieces of soil. At the same time, several bin support bases 21 can support the soil so that the rotating alloy breaker knives 45 can cut the soil multiple times and continuously, thereby reducing the problem of larger pieces of soil being transferred to the spiral spoiler 12 and getting stuck.

[0037] according to Figure 2 As shown, a support frame 24 is fixedly connected away from the top of the mounting bracket 23; a salt / humidity sensor 25 is fixedly connected to the top of the support frame 24, and the salt / humidity sensor 25 is located at the top of the soil processing bin 2. A control module is provided on the outer wall of the soil processing bin 2, and the salt / humidity sensor 25 and the servo motor 34 are electrically connected to the control module; when the material in the soil processing bin 2 reaches a preset height, the salt / humidity sensor 25 (such as an infrared sensor, which emits modulated light pulses through an infrared LED or a laser diode, and the target object reflects the infrared light, which is received by the photodiode and calculated by the flight time or light intensity change) To measure the distance or detect the object), the height can be detected. Subsequently, the servo motor 34 can be turned off in conjunction with the control module, so that the height in the soil processing bin 2 gradually moves downward and leaves the preset height. The servo motor 34 can be started again to transport the soil. Under the action of the salt / humidity sensor 25, this step can improve the flexibility of the end of the conveyor belt 33 in unloading, and reduce the problem that the height in the soil processing bin 2 gradually increases and is transferred to the outside because some soils are large and need to be sheared multiple times. At the same time, when the amount of soil in the soil processing bin 2 is appropriate, the rotating alloy breaker 45 can also be used to shear the soil.

[0038] according to Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the hydraulic jacking mechanism 5 includes two top plates 51 sliding on the top of the sealed processing chamber 22. The top plates 51 are slidably connected to the top of the sealed processing chamber 22 to ensure flexibility of movement. The top plates 51 can generate thrust through the contact between the plate surface and the soil, pushing the soil in the central area to diffuse to the periphery. The symmetrical distribution of the two top plates can balance the thrust and avoid the sealed processing chamber 22 from being offset by force. The hydraulic jacking mechanism 5 also includes two guide columns 52 fixed on the inner wall of the top plate 51. The guide columns 52 are rigid rod-shaped structures. Their function is to provide guidance for the movement of the top plate 51 and limit the top plate to only move axially along the crushing unit frame 41 to avoid The lateral deviation caused by uneven force ensures that the jacking action is stable and controllable; the joint shaft 53 fixed to the ends of the two guide columns 52 adopts a rotatable sleeve structure, which can not only be rigidly connected to the guide columns 52 to transmit thrust, but also can flexibly adjust the angle with the rotation of the rotating shaft 42 to avoid jamming during the threaded connection. It is threadedly connected to the reciprocating thread 46 on the outer wall of the rotating shaft 42, and the reciprocating thread 46 on the outer wall of the rotating shaft 42 enables the joint shaft 53 to complete the "upward movement-downward movement" cycle when the rotating shaft rotates, providing continuous reciprocating power for the top plate 51, and realizing the dynamic working mode of the hydraulic jacking mechanism.

[0039] When the rotating shaft 42 drives the alloy breaker 45 to rotate, the reciprocating thread 46 on its outer wall acts on the joint shaft 53 synchronously: the helix angle of the thread drives the joint shaft 53 to move upward in the axial direction first, and pushes the top plate 51 to lift the sealed processing chamber 22 upward through the guide column 52; when the joint shaft 53 moves to the end point of the reciprocating thread 46, the thread trajectory is reversed, driving the joint shaft 53 to move downward, and the top plate 51 falls accordingly, and the sealed processing chamber 22 is reset. During this reciprocating motion, the sealed processing chamber 22 is pushed by the top plate 51 to achieve a small up and down movement, and the inclined surface at its top forms a synergistic relationship with the thrust generated by the motion: the soil blocks accumulated in the center are lifted up by the lifting force of the sealed processing chamber 22, and then slide to the surrounding areas with the help of the inclined surface, realizing the transfer from the center to the periphery.

[0040] according to Figure 1As shown, two load-bearing beams 54 are fixed to the side walls of the two top plates 51, which function is to form a whole structure by connection, disperse the stress generated when the top plate 51 moves, and when the top plate 51 bears the reaction force of the soil in reciprocating motion, the load-bearing beam 54 can transmit the force to the two top plates, avoid the deformation of a single top plate due to force concentration, and at the same time, the rotating connection (using bearings) with the rotating shaft 42 neither affects the rotation of the rotating shaft 42 nor provides support for the top plate 51, limits the sway of the top plate during the movement process, improves the structural stability, ensures the axial movement of the top plate 51, and avoids the deviation or wear of the components caused by the sway; the protective plate 55 fixed to the outer wall of the load-bearing beam 54 has a double function of downward inclination: one is to shield the falling dust and soil particles in the soil treatment bin 2, and prevent them from falling to the reciprocating thread 46 and joint shaft 53 position of the rotating shaft 42; the second is to guide the impurities blocked by the inclined surface to the direction of the threaded connection area, avoiding the secondary falling of the impurities accumulated on the protective plate; when the two top plates 51 reciprocate with the hydraulic jacking mechanism 5, the load-bearing beam 54 moves synchronously, and its connection characteristics continuously provide support for the top plate, reduce the sway amplitude of the top plate caused by reciprocating motion, and ensure the smoothness of the hydraulic jacking mechanism operation; at the same time, the protective plate 55 moves synchronously with the load-bearing beam, always keeps shielding the threaded connection area, reduces the adhesion of impurities to the reciprocating thread 46 and the joint shaft 53, avoids the problems such as increased friction resistance and accelerated wear caused by impurities entering the thread gap, prolongs the service life of the joint shaft and the reciprocating thread, and reduces the maintenance frequency caused by the jamming or component wear of the equipment.

[0041] The effect achieved by the whole mechanism is:

[0042] The stable support 1 is installed in the designated working area, and then the soil to be treated is transferred to the feeding box 35, and the servo motor 34 is started, which functions to automatically and continuously convey the soil by driving the transmission belt 33 to move. The transmission belt 33 transfers the soil in the feeding box 35 to the soil treatment bin 2 to realize directional conveying of the material. The falling soil is guided into the soil treatment bin 2 by the guide plate 26, which functions to guide the soil to fall into the treatment area and prevent soil overflow to cause waste or pollution. The dynamic crushing unit 4 is matched to cut large pieces of soil, which functions to crush large pieces of soil into small pieces, increase the contact area of the soil with the subsequent microwave, and create favorable conditions for disinfection and salt reduction treatment. The variable speed motor 13 is started, and through the meshing transmission of the transmission gear 14 and the main shaft drive shaft 15, the microwave resonant cavity 11 is slowly counterclockwise rotated on the stable support 1, realizing efficient transmission and conversion of power. At the same time, the uppermost opening of the spiral spoiler 12 is matched with the sealed treatment cabin 22 to transfer the soil in the soil treatment bin 2 to the spiral spoiler 12. The spiral structure of the spiral spoiler 12 functions to layer the soil to avoid accumulation and ensure that each layer of soil can fully contact the microwave. When there is soil between the spiral spoiler 12 and the sealed treatment cabin 22, the microwave generator in the sealed treatment cabin 22 is started, which functions to kill bacteria and insect eggs in the soil and reduce the salt content of the soil by using microwave energy. By adjusting the output shaft speed of the variable speed motor 13, the discharge speed of the soil in the spiral spoiler 12 and the microwave treatment duration can be changed, which functions to adapt to the processing needs of different soils (such as salt content and adhesion difference). The material discharged from the bottom of the microwave resonant cavity 11 is transferred to the next station by external conveying devices.

[0043] When it is necessary to cut large pieces of soil in the soil processing bin 2, the microwave resonant cavity 11 rotates while the rotating shaft 42 drives the two alloy breaker knives 45 to rotate. Its function is to shear large pieces of soil through the high-speed rotating blades; the equidistant gaps formed by the several bin support bases 21 have the function of providing support for large pieces of soil to ensure that the soil is under stable force during cutting, and secondly, serving as a discharge channel to allow the sheared small pieces of soil to be discharged smoothly to avoid blockage; the alloy breaker knives 45 are fixed by bolts, and their function is to facilitate disassembly and maintenance. When the blades are worn, they can be quickly replaced to ensure crushing efficiency; when the material in the soil processing bin 2 reaches the preset height, the salt / humidity sensor 25 detects it and cooperates with the control module to turn off the servo motor 34, which is to realize automatic adjustment of feeding. Control to avoid excessive accumulation of soil. After the height is lower than the preset value, the servo motor 34 is restarted to continue feeding, ensuring that the amount of soil in the processing chamber is appropriate and optimizing the crushing and microwave treatment effects. When the rotating shaft 42 rotates, the reciprocating thread 46 drives the joint shaft 53 to move up and down, pushing the sealed processing chamber 22 to move. Its function is to transfer the soil blocks accumulated in the middle to the surrounding areas through the up and down movement of the sealed processing chamber 22 and the top inclined surface, so as to avoid uneven treatment caused by excessive accumulation of soil in the central area; when the two top plates 51 move, they drive the load-bearing beams 54 to move synchronously, thereby enhancing structural stability and reducing shaking; the protective plate 55 blocks falling dust, and its function is to prevent impurities from adhering to the reciprocating thread 46 and the joint shaft 53, reducing wear and jamming risks and extending component service life.
