In view of this, we propose a water spray device for soil remediation. In view of this, we propose a water spray device for soil remediation. Utility Model Content

[0006] The purpose of the utility model is to provide a water spraying device for soil remediation to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a water spraying device for soil remediation, comprising a base, four rollers and a handle, wherein the handle is fixedly mounted on the base, and the four rollers are rotatably mounted on the base, and the utility model is characterized in that it also includes:

[0008] A liquid storage tank, wherein the liquid storage tank is fixedly mounted on the top of the base, and a feed hopper is fixedly mounted on the top of the liquid storage tank, a water pump is fixedly mounted on the bottom of the inner cavity of the liquid storage tank, a water pipe 1 is fixedly mounted on the water outlet end of the water pump, one end of the water pipe 1 penetrates the liquid storage tank and extends to the outside and is threadedly connected with a water pipe 2, a check sleeve is fixedly mounted on one end of the water pipe 1, two contacting sealing strips are fixedly mounted at the outlet of the check sleeve, and the check sleeve is located in the water pipe 2, a fixed block is plugged and mounted in the water pipe 2, and a filter is symmetrically fixedly mounted in the fixed block;

[0009] A fixing assembly, the fixing assembly is located on the fixing block and is used to fix the fixing block in the second water pipe;

[0010] A water spray chamber, which is opened on the base and located at the front side of the liquid storage tank;

[0011] Water pipe three, the water pipe three is threadedly installed in the other end of the water pipe two, and a plurality of spray heads are fixedly installed on the bottom side of the water pipe three and located in the water spray cavity;

[0012] A working chamber, the working chamber is opened in the base and located at the front side of the water spray chamber, a U-shaped column is slidably installed in the working chamber, and both ends of the U-shaped column pass through the front side of the working chamber and extend to the outside, a rotating rod is rotatably installed between the two ends of the U-shaped column and located at the front side of the base, and a plurality of soil turning blades are fixedly installed on the rotating rod;

[0013] A driving assembly is located in the base and is used to drive the U-shaped column to rise and fall and the rotating rod to rotate.

[0014] In the present technical solution, the user first holds the handle with his hand and then pushes the entire device. When the roller is subjected to a forward thrust, it drives the entire device forward. When the entire device is moved by the user to the position where the soil needs to be repaired, the user stops applying forward force to the entire device through the handle, and the entire device stops at this time. At this time, the driving assembly is started, and the driving assembly drives the U-shaped column to descend, and the U-shaped column drives the rotating rod and several soil-turning blades to descend until part of the structure of the soil-turning blade penetrates into the soil. Subsequently, the driving assembly will also drive the rotating rod to rotate, and the rotating rod will drive several soil-turning blades to rotate. When the soil-turning blades rotate, they have an excavation and crushing effect on deep and hard soil, allowing the repair fluid for repairing the land to enter deeper soil more smoothly, preventing the soil repair fluid from being unable to fully penetrate the soil, thereby causing waste of soil repair fluid; then the water pump is started, and the water pump will extract the repair fluid in the liquid storage tank. The liquid will first pass through water pipe one and the check sleeve. Under the action of water pressure, the tail end of the check sleeve will expand and open. When the repair liquid quickly passes through the two sealing strips, the two sealing strips will be expanded to form a circular mouth and discharged into water pipe two, and then enter water pipe three through the filtration of two filters. Finally, through several nozzles, the repair liquid is sprayed onto the soil after the crushing is completed. When the liquid storage tank is used for a long time, impurities are likely to be generated inside it. These impurities will be intercepted and filtered by the filter set in water pipe two. When the filter is used for a period of time, we need to replace the filter. The personnel replace the fixing block together with the filter through the fixing assembly. Under the action of the thread, turn water pipe two, and you can directly take water pipe two out from water pipe one and water pipe three. At this time, you can clean water pipe two separately. By replacing the filter and removing and cleaning water pipe two, it is ensured that the impurities precipitated after long-term use of the liquid storage tank are effectively filtered. At the same time, it is avoided that several nozzles are blocked by impurities and affect the smoothness of the spraying.

[0015] In the above technical solution, further, the driving component includes:

[0016] A hydraulic cylinder, wherein the hydraulic cylinder is fixedly mounted on the top of the base, and an output shaft of the hydraulic cylinder passes through the top of the base, extends into the working chamber and is fixed to the U-shaped column;

[0017] A fixed plate, the fixed plate is fixedly mounted on one side of the U-shaped column and is located in the working chamber, and a motor is fixedly mounted on the top of the fixed plate;

[0018] Transmission wheel 1 and transmission wheel 2, wherein the transmission wheel 1 and the transmission wheel 2 are respectively fixedly mounted on the output shaft of the motor and the rotating rod, and a transmission belt is installed between the transmission wheel 1 and the transmission wheel 2;

[0019] A storage battery is fixedly mounted on the top of the base and located at the front side of the water spray chamber.

[0020] In the present technical scheme, it is ensured that the hydraulic cylinder can be fixed on the top of the base so that the output shaft of the hydraulic cylinder can drive the U-shaped column to slide up and down normally, and the U-shaped column can drive the fixed plate, the motor, the transmission wheel 1, the transmission belt, the transmission wheel 2, the rotating rod and several soil-turning blades to move up and down together. When part of the structure of the soil-turning blade penetrates into the soil, the motor is started at this time, and the motor is powered on to start working. The output shaft of the motor will drive the transmission wheel 1 to rotate, and then the transmission wheel 1 will drive the transmission belt to transmit together, and the transmission belt will drive the transmission wheel 2 to rotate together, and the transmission wheel 2 will drive the rotating rod to rotate together, and finally, the rotating rod will drive several soil-turning blades to rotate. When the soil-turning blades rotate, they have an excavation and crushing effect on the deep and hard soil, which can allow the repair fluid for repairing the land to enter the deeper soil more smoothly, preventing the soil repair fluid from being unable to fully penetrate the soil, thereby causing waste of soil repair fluid.

[0021] In the above technical solution, further, the output shaft of the hydraulic cylinder is slidably connected to the base, the fixed plate is slidably connected to the working chamber, and the transmission belt is slidably connected to the base.

[0022] In this technical solution, it is ensured that the output shaft of the hydraulic cylinder can move up and down in the base, that the fixed plate can move up and down in the working chamber, and that the transmission belt can move up and down normally in the base.

[0023] In the above technical solution, further, the hydraulic cylinder, water pump and motor are all electrically connected to the battery.

[0024] In this technical solution, it is ensured that the battery can provide electrical energy for the hydraulic cylinder, water pump and motor.

[0025] In the above technical solution, further, the fixing assembly includes:

[0026] Two threaded holes 1, the two threaded holes 1 are symmetrically opened on the water pipe 2;

[0027] Two threaded holes 2 are symmetrically arranged on the fixing block, and the two threaded holes 1 are respectively connected with the two threaded holes 2. Bolts are installed in the internal threads of the threaded holes 2, and the lower ends of the bolts pass through the threaded holes 1. The lower ends of the bolts are threadedly connected with the threaded holes 1.

[0028] In this technical solution, when the filter has been used for a period of time, we need to replace the filter. The personnel use tools to turn the two bolts, and the two bolts will be taken out from the two threaded holes two and the two threaded holes one respectively. At this time, the user can take out the fixing block together with the filter from the water pipe two, and then the filter can be replaced.

[0029] In the above technical solution, further, the diameter of the filter is smaller than the inner diameter of the second water pipe, and sealing gaskets are fixedly installed on both sides of the fixed block.

[0030] In the technical solution, under the action of the sealing gasket, when the repair liquid passes through the fixing block, the repair liquid will not flow out from the gap between the fixing block and the water pipe 2, so that the sealing effect is better.

[0031] In the above technical solution, further, the cross-section of one end of the check sleeve is a circular structure, and the cross-section of the other end is a rectangular structure.

[0032] In the present technical solution, when a large amount of repair fluid passes through the check sleeve, one end of the rectangular structure will be expanded by the repair fluid; when the repair fluid stops passing through the check sleeve, the check sleeve will return to its original shape, and the two sealing strips will be in close contact, effectively preventing impurities from flowing back into the water pipe. Because the check sleeve is made of chloroprene rubber, it has a very good deformation and rebound effect.

[0033] In the above technical solution, further, the water pipe 1 is tightly bonded to the liquid storage tank.

[0034] In this technical solution, it is ensured that the repair liquid in the liquid storage tank will not flow out from the gap between the water pipes, thereby preventing the repair liquid from leaking.

[0035] In the above technical solution, further, the top of the motor is lower than the top of the U-shaped column.

[0036] In this technical solution, it is ensured that when the U-shaped column drives the motor to move up and down, it will not affect the motor.

[0037] The beneficial effects of the utility model are:

[0038] 1. For the water spray device for soil remediation, the user first holds the handle with his hand, and then pushes the entire device. When the roller is subjected to a forward thrust, it will drive the entire device to move forward. When the entire device is moved by the user to the position where the soil needs to be repaired, the user stops applying forward force to the entire device through the handle, and the entire device will stop at this time. At this time, the driving assembly is started, and the driving assembly will drive the U-shaped column to descend, and the U-shaped column will drive the rotating rod and several soil-turning blades to descend until part of the structure of the soil-turning blade penetrates into the soil. Subsequently, the driving assembly will also drive the rotating rod to rotate, and the rotating rod will drive several soil-turning blades to rotate. When the soil-turning blades rotate, they have an excavation and crushing effect on deep and hard soil, which can allow the repair fluid for repairing the land to enter deeper soil more smoothly, preventing the soil repair fluid from being unable to fully penetrate the soil, thereby causing waste of soil repair fluid.

[0039] 2. The water spraying device for soil remediation starts the water pump, which will extract the repair liquid in the liquid storage tank. The extracted liquid will first pass through the water pipe 1 and the check sleeve. Under the action of water pressure, the tail end of the check sleeve will expand and open. When the repair liquid quickly passes through the two sealing strips, the two sealing strips will be expanded to form a circular opening and discharged into the water pipe 2, and then enter the water pipe 3 through the filtration of two filter screens. Finally, through a number of nozzles, the repair liquid is sprayed onto the soil after the crushing is completed. When the liquid storage tank is used for a long time, impurities are likely to be generated inside, and these impurities will be discharged by the water pipe. The filter screen set in water pipe 2 is used for interception and filtration. When the filter screen has been used for a period of time, we need to replace the filter screen. The personnel replace the fixing block together with the filter screen through the fixing assembly. Under the action of the thread, turn water pipe 2, and water pipe 2 can be directly taken out from water pipe 1 and water pipe 3. At this time, water pipe 2 can be cleaned separately. By replacing the filter screen and dismantling and cleaning water pipe 2, it is ensured that the impurities precipitated after long-term use of the liquid storage tank are effectively filtered. At the same time, it is avoided that several nozzles are blocked by impurities and affect the smoothness of spraying. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] Among them, when a large amount of repair fluid passes through the check sleeve 24, one end of the rectangular structure will be expanded by the repair fluid. When the repair fluid stops passing through the check sleeve 24, the check sleeve 24 will return to its original state, and the two sealing strips 25 will be in close contact, effectively preventing impurities from flowing back into the water pipe 14. Because the check sleeve 24 is made of chloroprene rubber, the deformation and rebound effect is very good.

[0087] Embodiment 8:

[0088] This embodiment provides a water spraying device for soil remediation, which, in addition to the technical solutions of the above embodiments, also has the following technical features: a water pipe 14 is tightly bonded to a liquid storage tank 2.

[0089] Among them, it is ensured that the repair liquid in the liquid storage tank 2 will not flow out from the gap between the water pipe 1 and 14, thereby preventing the repair liquid from leaking.

[0090] Embodiment 9:

[0091] This embodiment provides a water spraying device for soil remediation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the top of the motor 10 is lower than the top of the U-shaped column 12.

[0092] It is ensured that when the U-shaped column 12 drives the motor 10 to move up and down, it will not affect the motor 10.

[0093] Working principle: the user first holds the handle 4 with his hand, and then pushes the whole device. When the roller 5 is subjected to a forward thrust, it will drive the whole device to move forward. When the whole device is moved by the user to the position where the soil needs to be repaired, the user stops applying forward force to the whole device through the handle 4, and the whole device will stop at this time. At this time, the hydraulic cylinder 15 is started, and the hydraulic cylinder 15 is powered on to start working. The output shaft of the hydraulic cylinder 15 normally drives the U-shaped column 12 to slide up and down, and the U-shaped column 12 can drive the fixed plate 23, the motor 10, the transmission wheel 1 7, the transmission belt 8, the transmission wheel 2 11, the rotating rod 9 and a plurality of soil-turning blades 6 to move up and down together. When part of the structure of the soil-turning blade 6 penetrates into the soil, the motor 10 is started at this time, and the motor 10 is powered on to start When the tillage machine 10 starts working, the output shaft of the motor 10 will drive the transmission wheel 1 7 to rotate, and then the transmission wheel 1 7 will drive the transmission belt 8 to transmit together, and the transmission belt 8 will drive the transmission wheel 2 11 to rotate together, and the transmission wheel 2 11 will drive the rotating rod 9 to rotate together, and finally, the rotating rod 9 will drive a number of tillage blades 6 to rotate. When the tillage blades 6 rotate, they have an excavation and crushing effect on the deep and hard soil, which can make the repairing liquid for repairing the land enter the deeper soil more smoothly, and prevent the soil repairing liquid from not being able to fully penetrate the soil, thereby causing waste of the soil repairing liquid; then start the water pump 20, the water pump 20 will extract the repairing liquid in the liquid storage tank 2, and the extracted liquid will first pass through the water pipe 14 and the check sleeve 24. Under the action of water pressure, the check sleeve The tail end of the sleeve 24 will expand and open, and when the repair liquid passes through the two sealing strips 25 quickly, the two sealing strips 25 will be expanded to form a circular mouth and discharged into the water pipe 2 17, and then filtered through the two filter screens 19 into the water pipe 3 18, and finally the repair liquid is sprayed onto the soil after the crushing through a number of nozzles 13. When the liquid storage tank 2 is used for a long time, impurities are likely to be generated inside, and these impurities will be intercepted and filtered by the filter screen 19 set in the water pipe 2 17. When the filter screen 19 is used for a period of time, we need to replace the filter screen 19. The personnel use tools to rotate the two bolts 26, and the two bolts 26 will be taken out from the two threaded holes 21 and the two threaded holes 1 22 respectively. At this time, the user can remove the fixing block 27 together with the filter screen 19 from the water pipe 2 17 After the filter screen 19 and the fixing block 27 are replaced, the new fixing block 27 together with the new filter screen 19 are inserted back into the water pipe 2 17, and then the two bolts 26 are rotated to fix the bolts 26 in the threaded holes 21 and 1 22. When there are impurities in the water pipe 2 17, the water pipe 2 17 can be rotated under the action of the thread to directly remove the water pipe 2 17 from the water pipe 1 14 and the water pipe 3 18. At this time, the water pipe 2 17 can be cleaned separately. By replacing the filter screen 19 and removing and cleaning the water pipe 2 17, it is ensured that the impurities precipitated after the long-term use of the liquid storage tank 2 are effectively filtered, and at the same time, it is avoided that a number of nozzles 13 are blocked by impurities and affect the smoothness of the spraying.
