[0035] During the deployment process, the drive motor 25 is started in advance, the transmission belt 27 drives the tank body 33 to move horizontally through the suspension arm 31, the rack 622 forces the gear 625 to rotate through the connecting shaft 621 to drive the rotating disc 61, and the rolling ball 624 is closely attached to the smooth surface at the top of the erected track 21, which not only converts the sliding friction in the rotating process of the gear 625 into rolling friction, greatly reduces the transmission resistance, and significantly improves the transmission efficiency, but more importantly, the close attachment of the rolling ball 624 and the erected track 21 forms a stable suspension support structure, which transmits most of the weight of the tank body 33 to the erected track 21 through the suspension support disc 623, effectively avoids the fatigue damage of the components caused by the weight concentrated on the transmission belt 27 or the suspension arm 31, and ensures that the tank body 33 remains in a horizontal stable state during movement and stirring. When the rotating disc 61 rotates, the rotating shaft 63 rotates inside the tank body 33, the stirring plate 64 performs transverse shear stirring on the modified liquid, and the stirring auger 65 performs spiral advancing motion to stir the modified liquid deposited at the bottom of the tank body 33, forming a three-dimensional stirring network to realize full-range and dead-angle-free stirring of the modified liquid inside the tank body 33, completely preventing the precipitation and stratification of the modified liquid due to standing, ensuring that the concentration of the modified liquid remains uniform throughout the deployment process, and through the meshing transmission of the gear 625 and the rack 622, the stirring can be realized by the movement of the tank body 33 without additional power source, saving energy while ensuring that the stirring and movement are synchronized.

[0036] When the modified liquid is uniformly stirred inside the tank body 33, the water pump 71 is started to pump the modified liquid from the drain hopper 34 to the spray horizontal pipe 76, the double-shaft motor 74 drives the worm 75 to rotate, the worm gear 79 engaged with the worm 75 drives the vertical pipe 78 and the spray side pipe 710 to rotate, and the spray nozzle 711 moves in a ring shape, forming a certain range of circular spray area. The modified liquid is sprayed out in a mist state at high speed, which not only ensures the contact area between the modified liquid and the soil, but also avoids the waste caused by large particles, further increasing the density and uniformity of the spray. Example 2

[0037] The above soil improvement device is found to have the following problems in long-term use: when improving the pH value of the soil, the modified liquid used is a mixture of raw materials such as lime or wood ash dissolved in water, and then the upper clear liquid is taken out and sprayed onto the soil to improve the pH value of the soil. Even if the upper clear liquid is used as the modified liquid, impurities are still mixed in it, which causes the impurities in the modified liquid to block the device and affect the normal use of the device. Therefore, the present application is further improved.

[0038] As Figures 10-14As shown, the soil improvement device further comprises a liquid level sensor 9 fixedly installed inside the drain hopper 34, which is used to detect the liquid level of the improvement liquid in the tank 33; a debris discharge port provided outside the bottom of the drain hopper 34 and in communication with the collection cavity 1002, and a screw cap detachably provided on the debris discharge port for plugging the same.

[0039] The filter module 10 comprises a filter screen 1001 rotatably mounted on the inner bottom of the drain hopper 34, the outer wall of the filter screen 1001 is in close contact with the inner wall of the drain hopper 34; a collection cavity 1002 is arranged on the bottom of the drain hopper 34 and located on the outer side of the filter screen 1001, the collection cavity 1002 is communicated with the inside of the drain hopper 34 through a plurality of through holes, the modified liquid in the collection cavity 1002 and the drain hopper 34 can communicate with the filter screen 1001 through the through holes, and the impurities in the collection cavity 1002 cannot enter the drain hopper 34 through the through holes and the filter screen 1001; a three-way electromagnetic valve 1003 is fixedly communicated with the output end of the water pump 71, one output end of the three-way electromagnetic valve 1003 is communicated with the collection cavity 1002, and the other output end is communicated with the spray horizontal pipe 76, the three-way electromagnetic valve 1003 can control the flow direction of the modified liquid pumped out from the water pump 71, that is, by adjusting the state of the three-way electromagnetic valve 1003, the modified liquid can be pumped into the spray horizontal pipe 76 alone, the modified liquid can be pumped into the collection cavity 1002 alone, and the modified liquid can be pumped into the spray horizontal pipe 76 and the collection cavity 1002 at the same time; a communication groove 1004 is arranged on the top of the channel 712 and extends to the inner side of the drain hopper 34; a limiting pin 1005 is sealingly and slidingly arranged in the communication groove 1004, the limiting pin 1005 is in a cylindrical shape and can relatively sealingly rotate in the communication groove 1004; a first elastic member 1006 is arranged between the limiting pin 1005 and the communication groove 1004; a limiting groove 1007 is arranged on the outer side of the filter screen 1001, the first elastic member 1006 can apply a pushing force to the limiting pin 1005, so that the limiting pin 1005 is clamped into the limiting groove 1007; a sliding groove 1008 is arranged on the outer side of the stirring auger 65; a spherical lug 1009 is movably arranged in the sliding groove 1008, the end of the sliding groove 1008 is arranged in a conical shape, so that the spherical lug 1009 can only extend out of the sliding groove 1008 by a part and cannot completely come out of the sliding groove 1008; a second elastic member 1010 is arranged between the sliding groove 1008 and the spherical lug 1009; a plurality of semispherical grooves 1011 are arranged in an annular array on the inner side of the filter screen 1001, the second elastic member 1010 can provide a pushing force to the spherical lug 1009, so that the spherical lug 1009 is located at the end of the sliding groove 1008, and at this time a part of the spherical lug 1009 extends out of the sliding groove 1008 and is clamped in the semispherical groove 1011 at the corresponding position; an installation groove 1012 is arranged on the top of the channel 712 and located on one side of the communication groove 1004, a gas passage 1013 is arranged on the top of the installation groove 1012 and communicated with the outside; a sealing sliding block 1014 is slidingly arranged in the installation groove 1012 and sealingly arranged with the installation groove 1012;The connecting rod 1015 is fixedly arranged at one end of the limiting pin 1005, and is screwed at the other end into the installation groove 1012 from the communication groove 1004 and is screwed with the sealing sliding block 1014, and the connecting rod 1015 can synchronously transmit the force received by the sealing sliding block 1014 to the limiting pin 1005.

[0040] It should be noted that, since the spherical protrusion 1009 and the semispherical recess 1011 are in spherical clamping connection, and only a small part of the spherical protrusion 1009 is clamped in the semispherical recess 1011, the spherical protrusion 1009 can slide in the sliding groove 1008, thus, when the limiting pin 1005 is not clamped into the limiting groove 1007, the filter screen 1001 can be driven to rotate synchronously by the clamping action of the spherical protrusion 1009 and the semispherical recess 1011 during the rotation of the stirring auger 65, when the limiting pin 1005 is clamped into the limiting groove 1007, the position of the filter screen 1001 is limited, and during the rotation of the stirring auger 65, the spherical protrusion 1009 will slide into and out of each semispherical recess 1011 in turn and repeatedly.

[0041] It should be further noted that, when the sealing sliding block 1014 is installed, the sealing sliding block 1014 is first installed from the opening end of the installation groove 1012 to the inside of the installation groove 1012, and the sealing sliding block 1014 is pushed to slide towards the groove bottom of the installation groove 1012, when the sealing sliding block 1014 does not pass the air passage 1013, the space between the groove bottom of the installation groove 1012 and the sealing sliding block 1014 is in communication with the outside through the air passage 1013, and the outside air enters the space between the groove bottom of the installation groove 1012 and the sealing sliding block 1014 through the air passage 1013; when the sealing sliding block 1014 passes the air passage 1013, the space between the groove bottom of the installation groove 1012 and the sealing sliding block 1014 is in a closed state, and as the sealing sliding block 1014 continues to slide towards the groove bottom of the installation groove 1012, the gas in the closed space is compressed, and the gas pressure becomes larger, that is, the gas in the closed space at this time will exert a pushing force on the sealing sliding block 1014 in a direction away from the groove bottom of the installation groove 1012; when the water pump 71 is operated at a standard power, the pushing force of the first elastic member 1006 overcomes the pushing force of the gas in the closed space on the sealing sliding block 1014 and the suction force of the limiting pin 1005 generated by the modified liquid passing through the channel 712, so that the limiting pin 1005 is clamped in the limiting groove 1007, at this time, the gas in the closed space is in a compressed state, and the compressed gas exerts a pushing force on the limiting pin 1005 away from the limiting groove 1007 through the sealing sliding block 1014 and the connecting rod 1015.

[0042] The middle part of the filter screen 1001 is provided with a gap 1016, the height of the gap 1016 is consistent with the channel 712, and the middle part of the gap 1016 is provided with a support rod, so as to ensure the overall strength of the filter screen 1001. When the filter screen 1001 rotates to the position where the gap 1016 corresponds to the channel 712, the impurities in the drain pan 34 will be extracted together with the modified liquid by the water pump 71. When the filter screen 1001 rotates to the position where the gap 1016 is misaligned with the channel 712, the filter screen 1001 filters the modified liquid extracted by the water pump 71, and the impurities stay in the drain pan 34.

[0043] It should be noted that the water pump 71, the liquid level sensor 9 and the three-way electromagnetic valve 1003 are all electrically connected to the controller of the device. The controller is a prior art and will not be described here. The liquid level sensor 9 can transmit the monitored liquid level to the controller, and the controller processes the received signal to calculate the liquid level drop rate of the modified liquid in the tank 33 per unit time, and compares it with the standard value of the liquid level drop rate of the modified liquid in the tank 33 when the modified liquid is normally sprayed. When the calculated liquid level drop rate is less than the standard value, it indicates that the filter screen 1001 is not smooth due to the presence of impurities in the drain pan 34, so the amount of modified liquid sprayed per unit time is reduced, and the impurities in the drain pan 34 need to be cleaned.

[0044] When the liquid level in the tank 33 is lower than the liquid level sensor 9 during use of the soil modification device, the liquid level sensor 9 transmits a signal to the controller, and the controller issues an alarm through an alarm to remind the staff that the modified liquid is about to run out and needs to be added to the tank 33 in time. The alarm is a prior art and will not be described here. The alarm is not shown in the figure.

[0045] In the process of improving liquid spraying, when the controller calculates that the improving liquid level drop rate is less than the standard value, the controller determines that there is impurity blockage in the drain pan 34, and the controller will automatically switch the state of the three-way electromagnetic valve 1003, so that the improving liquid is pumped into the collection cavity 1002 alone, and at the same time the power of the water pump 71 is increased, so that the water pump 71 increases the suction force of the improving liquid in the drain pan 34 through the channel 712. At this time, the limit pin 1005 overcomes the thrust of the first elastic member 1006 under the combined action of the increased suction force and the thrust of the gas in the closed space, and slides along the communication groove 1004 and slides out of the limit groove 1007, so as to release the limit of the filter screen 1001. The filter screen 1001 can freely rotate in the drain pan 34. With the continuous rotation of the stirring auger 65, the spherical lugs 1009 are clamped in the corresponding hemispherical grooves 1011, and the stirring auger 65 drives the filter screen 1001 to continuously rotate, so that the notch 1016 in the middle of the filter screen 1001 repeatedly corresponds to the channel 712, so that the impurities in the drain pan 34 are pumped into the collection cavity 1002 along with the improving liquid by the water pump 71. The improving liquid pumped into the collection cavity 1002 flows back to the drain pan 34 through the through hole and the filter screen 1001, and the impurities are collected in the collection cavity 1002.

[0046] After the water pump 71 increases the power for a certain period of time, the controller adjusts the water pump 71 to the standard power and switches the state of the three-way electromagnetic valve 1003, so that the improving liquid is pumped into the spray horizontal pipe 76 alone to perform the normal improving liquid spraying process. At this time, the limit pin 1005 is tightly pressed against the outside of the filter screen 1001 under the thrust of the first elastic member 1006. With the rotation of the filter screen 1001 driven by the stirring auger 65, when the filter screen 1001 rotates to the limit groove 1007 corresponding to the limit pin 1005, the limit pin 1005 is automatically clamped into the limit groove 1007, completing the automatic limiting of the filter screen 1001. At this time, the notch 1016 is misaligned with the channel 712, and the filter screen 1001 filters the improving liquid entering the channel 712. With the continuous rotation of the stirring auger 65, the spherical lugs 1009 will repeatedly slide into and out of each hemispherical groove 1011, so as to slightly knock the filter screen 1001 repeatedly, so as to produce slight vibration of the filter screen 1001, reducing the adhesion of impurities on the filter screen 1001.

[0047] The soil improvement device can switch the state of the three-way electromagnetic valve 1003 through the controller again to pump the improvement liquid into the spraying horizontal pipe 76 and the collection cavity 1002 at the same time when the impurities in the drainage hopper 34 are cleaned and the standard power is restored for the improvement liquid spraying, at this time, part of the improvement liquid pumped from the water pump 71 enters the spraying horizontal pipe 76 to spray the soil, and the other part enters the collection cavity 1002, thereby accelerating the water flow exchange between the drainage hopper 34 and the collection cavity 1002, promoting the mixing of the effective components remaining in the impurities into the drainage hopper 34, and avoiding the waste of the effective components in the impurities.

[0048] When the improvement liquid spraying work is completed, the impurities in the collection cavity 1002 can be cleaned, the appropriate amount of clean water is added to the inside of the tank body 33 through the feeding hopper 39, the screw cap at the impurity discharge port is removed, the state of the three-way electromagnetic valve 1003 is switched through the controller, the improvement liquid is pumped into the collection cavity 1002 alone, the power of the water pump 71 is increased, the notch 1016 repeatedly corresponds to the channel 712, the impurities remaining in the drainage hopper 34 follow the clean water into the collection cavity 1002, and the impurities in the collection cavity 1002 follow the clean water to be discharged from the impurity discharge port, thereby realizing the cleaning of the tank body 33, the drainage hopper 34 and the collection cavity 1002.

[0049] Through the cooperation of the liquid level sensor 9, the filter screen 1001, the collection cavity 1002, the three-way electromagnetic valve 1003 and the notch 1016, the filter screen 1001 can filter the improvement liquid entering the channel 712 during the normal spraying of the improvement liquid, thereby avoiding the impurities following the improvement liquid into the improvement liquid spraying module 7, and avoiding the blockage of the improvement liquid spraying module 7, when the liquid level sensor 9 monitors that the liquid level of the improvement liquid decreases at a rate less than a standard value, the controller can automatically determine that the impurities in the drainage hopper 34 are blocked and adjust the three-way electromagnetic valve 1003 and the water pump 71, so that the notch 1016 in the middle of the filter screen 1001 repeatedly corresponds to the channel 712, thereby pumping the improvement liquid containing impurities into the collection cavity 1002 to collect the impurities in the improvement liquid, avoid reducing the spraying efficiency due to the blockage of the filter screen 1001 by the impurities, and at the same time, since the collection cavity 1002 and the drainage hopper 34 are connected to each other, the effective substances remaining in the impurities in the collection cavity 1002 can still enter the drainage hopper 34 through the water flow, thereby avoiding the waste of the effective substances remaining in the impurities and ensuring the improvement effect of the improvement liquid on the soil.

[0050] Through the cooperation of the limiting pin 1005, the limiting groove 1007, the spherical protrusion 1009 and the semispherical groove 1011, the limiting pin 1005 and the limiting groove 1007 cooperate to limit the position of the filter screen 1001, the spherical protrusion 1009 continuously rotates with the stirring auger 65, so that the spherical protrusion 1009 can repeatedly slide into and out of each semispherical groove 1011, thereby slightly and repeatedly knocking the filter screen 1001, so that the filter screen 1001 produces slight vibration, reduces the adhesion of impurities on the filter screen 1001, and slows down the clogging of the filter screen 1001 during the spraying process.

[0051] By injecting clean water into the tank body 33 and switching the three-way electromagnetic valve 1003 to the state of pumping liquid to the pump collection cavity 1002 alone, while increasing the power of the water pump 71 so that the notch 1016 repeatedly corresponds to the channel 712, the impurities remaining in the tank body 33, the drain hopper 34 and the collection cavity 1002 can all be discharged from the impurity discharge port following the clean water, thereby achieving rapid cleaning of the impurities in the tank body 33, the drain hopper 34 and the collection cavity 1002.

[0052] Of course, the present application can have other various embodiments, and based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative labor shall fall within the scope of the present application.
