Description

Technical Field

[0001] This application relates to the technical field of soil treatment, and specifically discloses a spraying device for treating polluted soil. Background Art

[0002] With the large-scale popularization of facility agriculture, soil-borne diseases and stubborn weeds have become important factors leading to soil ecological imbalance, decline in cultivated land quality, affecting crop quality, and reduction in crop yield. Treating polluted soil can effectively improve the quality of cultivated land. During the process of treating polluted soil, soil disinfection is one of the essential treatment steps. Soil disinfection is mainly divided into two methods: chemical and physical. The chemical method is represented by fumigation technology, which mainly kills insects, bacteria, or weeds by applying drugs into the soil to achieve the purpose of preventing and controlling soil-borne diseases, insects, and weeds. The physical method mainly controls diseases, insects, and weeds by raising the internal temperature of the soil to the corresponding lethal level.

[0003] Taking high-temperature steam disinfection as an example, using a high-pressure steam boiler to spray high-temperature steam on the surface of the soil can not only improve the air permeability of the soil but also play a role in preventing and controlling pests and diseases. Usually, high-temperature steam disinfection is carried out in a greenhouse, and a heat-resistant film is covered on the surface of the land to be disinfected to slow down the heat dissipation of high-temperature steam and improve the disinfection effect on the land. Similarly, hot water disinfection is also a common disinfection method. Its principle is similar to that of high-temperature steam disinfection, but the soil is deeply plowed before disinfection to ensure that the hot water can penetrate the soil for full disinfection. In addition to having a strong disinfection effect, the hot water disinfection technology can also improve the physical and chemical properties of the soil.

[0004] In traditional high-temperature steam disinfection, not only are the disinfection conditions harsh, but high-temperature steam disinfection is for the disinfection of surface soil. When the depth of the soil to be disinfected reaches 50 cm or deeper, since the steam enters the soil slowly from the soil surface and the steam condenses into liquid water, the steam cannot penetrate into the soil below 50 cm, resulting in a poor disinfection effect on the deep soil. In traditional hot water disinfection, the soil needs to be deeply plowed before disinfection, which not only makes the disinfection process more cumbersome but also reduces the work efficiency of disinfecting the land. Therefore, in view of this, the inventor provides a spraying device for treating polluted soil to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that in the traditional process of treating polluted soil, the disinfection effect of high-temperature steam disinfection on deep soil is poor.

[0006] To achieve the above object, the basic scheme of the present invention provides a spraying device for treating polluted soil, including:

[0007] A frame, with a towing hook provided at one end of the frame;

[0008] A vertical driving member, provided on the frame and the output end of the vertical driving member is vertically downward and is provided with a mounting bracket. A plurality of plow blades are provided on one side of the mounting bracket close to the towing hook, and a sprinkler plate is provided on the other side of the mounting bracket;

[0009] A high-pressure steam boiler, provided on the frame and the high-pressure steam boiler is communicated with a water outlet pipe. A cavity communicated with the water outlet pipe is provided in the sprinkler plate. A plurality of water guide pipes communicated with the cavity are provided on the lower surface of the sprinkler plate, and a plurality of water outlet holes are provided on the side walls of the water guide pipes and the side walls of the sprinkler plate.

[0010] The principle and effect of this basic solution are as follows:

[0011] In the present invention, by providing a high-pressure steam boiler and a sprinkler plate, etc., the high-temperature steam of the high-pressure steam boiler is evenly sprinkled on the soil surface through the sprinkler plate, so as to achieve the purpose of disinfecting the soil surface with high-temperature steam. At the same time, the water guide pipe extends into the soil below to contact the soil and cool down, forming hot water discharged from the water outlet holes, and nearly penetrating into the soil, so as to achieve the effect of simultaneously disinfecting the land with high-temperature steam and hot water.

[0012] Further, a fixing frame is also provided on the frame. A plurality of telescopic rods are provided between the fixing frame and the mounting bracket. The telescopic rod includes a sliding rod fixedly connected to the mounting bracket and a fixed sleeve fixedly connected to the fixing frame. The top end of the sliding rod is slidably connected in the fixed sleeve. The cooperation of the fixing frame and the telescopic rod can not only improve the overall structural strength of the mounting bracket, but also play a role in limiting and guiding the vertical sliding of the mounting bracket.

[0013] Further, the water guide pipe is communicated with the fixed sleeve, and a water passage for communicating the fixed sleeve with the cavity is provided in the sliding rod. Through this setting method, the telescopic rod can be used for the transmission of high-temperature steam, avoiding the wear or even entanglement of the steam pipeline with the soil blocks in the soil due to the need to meet the vertical position adjustment of the sprinkler plate and using a long soft steam pipeline.

[0014] Further, a connection hole communicating with the water guide pipe is provided on the side wall of the fixed sleeve, a sealing block slidably and sealingly connected to the inner wall of the fixed sleeve is provided on the side wall of the sliding rod, and a water passage hole capable of conducting the connection hole and the water passage is provided on the sealing block. Through this setting method, the cavity in the sprinkler plate can be automatically connected and disconnected from the water guide pipe according to the height of the sprinkler plate. With a purely mechanical structure control, compared with the existing solenoid valve control for energizing the water guide pipe, the present invention not only has better stability, but also does not require manual control to open and close the water guide pipe, making the use process more convenient.

[0015] Further, a piston slidably connected in the fixed sleeve is provided at the top of the sliding rod, and a through hole through which high-temperature steam can pass is provided between the top and the bottom of the piston. The piston can prevent the sliding rod from separating from the fixed sleeve, and at the same time, the through hole can maintain the air pressure stability in the fixed sleeve, avoiding the situation of too high air pressure at one end of the piston and affecting the vertical position adjustment of the sliding rod.

[0016] Further, baffles are provided on the outer sides of the water guide pipes, and a driving mechanism for driving the baffles to rotate is provided on the vehicle frame. The baffles can prevent loose soil from blocking the water outlet holes on the side wall of the water guide pipe, and at the same time, can stir the soil on the side wall of the water guide pipe to prevent the soil from continuously adhering to the outer wall of the water guide pipe.

[0017] Further, the driving mechanism includes a first driving cavity provided in the cavity and allowing high-temperature steam to flow, and a rotating shaft rotatably connected in the water guide pipe. The top of the rotating shaft extends into the first driving cavity and is provided with a first fan blade, and the bottom of the rotating shaft extends out of the bottom of the water guide pipe and is provided with an ear piece connected to the baffle. This setting method enables the high-pressure steam to drive the first fan blade to rotate when passing through the first driving cavity, thereby driving the rotating shaft and the baffle to rotate to stir the soil on the side wall of the water guide pipe to prevent the soil from continuously adhering to the outer wall of the water guide pipe.

[0018] Further, the driving mechanism further includes a second driving cavity provided in the cavity and allowing high-temperature steam to flow. A sleeve is connected to the top of the water guide pipe, and the top of the sleeve extends into the second driving cavity and is provided with a second fan blade rotating in the opposite direction to the first fan blade. This setting method enables the high-pressure steam to drive the second fan blade, the sleeve and the water guide pipe to rotate when passing through the second driving cavity, avoiding the wall surface of the water guide pipe being fixed in one direction for a long time, resulting in the soil continuously contacting one or more wall surfaces and causing the water outlet holes to be blocked. At the same time, the rotating direction of the water guide pipe is opposite to that of the baffle, effectively improving the cleaning effect of the baffle on the soil on the side wall of the water guide pipe.

[0019] Furthermore, a partition is provided in the water sprinkling plate to separate the chamber, the first driving chamber and the second driving chamber from each other. This arrangement effectively prevents the pressure in the first driving chamber and the second driving chamber from being too low, thereby affecting the rotation of the baffle and the water pipe.

[0020] Furthermore, the number of the water pipes is the same as the number of the plow blades and they are arranged in parallel along the direction of the frame, the width of the plow blade is greater than the diameter of the water pipe and a guide plate is symmetrically arranged on the side wall of the plow blade close to the water pipe. This arrangement makes the movement path of the water pipe the same as that of the plow blade, so as to avoid the solid soil directly contacting the water pipe and affecting the normal movement and use of the water pipe, thereby improving the watering and disinfection performance of the soil.

The width of the plow blade is greater than the diameter of the water guide pipe 8 and guiding plates are symmetrically provided on the side wall of the plow blade close to the water guide pipe 8.

[0035] High-pressure steam boiler 2: The high-pressure steam boiler 2 is provided on the vehicle frame 1 and the high-pressure steam boiler 2 is communicated with a water outlet pipe 6, as Figure 5As shown, the water guide pipe 8 communicates with the fixed sleeve 4. The side wall of the fixed sleeve 4 is provided with a connection hole communicating with the water guide pipe 8. The side wall of the sliding rod 5 is provided with a sealing block 11 that is slidably and sealingly connected to the inner wall of the fixed sleeve 4. The sealing block 11 is provided with a water passage hole 12. A water passage communicating with the water passage hole 12 is provided in the sliding rod 5. The bottom of the sliding rod 5 extends into the sprinkler plate 7. A cavity that can communicate with the water passage is provided in the sprinkler plate 7. The top of the sliding rod 5 is provided with a piston 10 that is slidably connected in the fixed sleeve 4. A through hole through which high-temperature steam can pass is provided between the top and the bottom of the piston 10.

[0036] Baffles 9 are provided on the outer sides of the water guide pipes 8. A driving mechanism is provided in each sprinkler plate 7, such as Figures 6 to 8 As shown, the driving mechanism includes a first driving cavity, a second driving cavity provided in the cavity and allowing high-temperature steam to flow, and a rotating shaft 14 rotatably connected in the water guide pipe 8. The top of the rotating shaft 14 extends into the first driving cavity and is provided with a first fan blade 15. The bottom of the rotating shaft 14 extends out of the bottom of the water guide pipe 8 and is provided with an ear piece connected to the baffle 9. A sleeve is connected to the top of the water guide pipe 8. The top of the sleeve extends into the second driving cavity and is provided with a second fan blade 16 rotating in the opposite direction to the first fan blade 15. A partition plate 13 that divides the cavity into upper and lower parts and a protective shell 17 that covers the first driving cavity and the second driving cavity are provided in the sprinkler plate 7. The first driving cavity and the second driving cavity are respectively formed inside the protective shell 17.

[0037] In this embodiment, there are a total of two fixed sleeves 4 communicating with the high-pressure steam boiler 2, and the number of water guide pipes 8 and baffles 9 is three, that is, the number of both the first driving cavity and the second driving cavity is three. Taking the Figure 8 direction shown as an example, the first driving cavities communicate with each other. The right end of the rightmost first driving cavity communicates with the bottom of one of the sliding rods 5 for high-temperature steam to enter. The high-temperature steam flows from right to left and flows out from the left end of the leftmost first driving cavity, and enters the space below the partition plate 13 and the space between the outer wall of the protective shell 17 and the inner wall of the sprinkler plate, and is discharged from the water outlet holes of the sprinkler plate 7 or the water outlet holes of the water guide pipe 8. The second driving cavity is located below the partition plate 13. Each second driving cavity communicates with each other. The left end of the leftmost second driving cavity communicates with the bottom of the other sliding rod 5 for high-temperature steam to enter. The high-temperature steam flows from left to right and flows out from the right end of the rightmost second driving cavity, and enters the space below the partition plate 13 and the space between the outer wall of the protective shell 17 and the inner wall of the sprinkler plate, and is discharged from the water outlet holes of the sprinkler plate 7 or the water outlet holes of the water guide pipe 8. The bottom of the space between the partition plate 13, the outer wall of the protective shell 17 and the inner wall of the sprinkler plate communicates with the top surface of the water guide pipe 8 through a guide hole. Since the water guide pipe 8 rotates continuously, multiple guide holes can be provided at the top of the water guide pipe 8, and a sealing plate for blocking the top of the water guide pipe 8 is provided on the outer wall of the sprinkler plate. Of course, guide holes are also provided on the sealing plate to make the space between the outer wall of the protective shell 17 and the inner wall of the sprinkler plate communicate with the water guide pipe 8.

[0038] A bearing is used to connect the rotating shaft 14 and the partition plate 13, as well as the sleeve and the sealing plate.

[0039] In the implementation process of the present invention, when disinfecting the soil, a tractor or other towing vehicle is used to tow the vehicle frame 1 to slowly move along the land. The output end of the vertical driving member 3 moves downward, so that the sprinkler plate 7 is located about 5 cm above the soil, while the plow blade and the water guide plate extend into the soil. During the movement of the vehicle frame 1, the plow blade contacts the land, making the solid soil become loose. During the downward movement of the vertical driving member 3, the sliding rod 5 moves downward, causing the water passage hole 12 of the sealing block 11 to communicate with the connecting hole. High-temperature steam enters the sprinkler plate 7 and the water guide pipe 8, so as to achieve the purpose of disinfecting the soil surface with high-temperature steam. Moreover, since the water guide pipe 8 extends below the soil and contacts the soil, the soil cools down the high-temperature steam in the water guide pipe 8, and the hot water is discharged from the water outlet hole and seeps into the soil, so as to achieve the effect of hot water disinfection. During this process, the water guide pipe 8 contacts the soil, and due to the action of the plow blade, the side surface of the water guide pipe 8 facing the oblique side of the plow blade contacts the soil more frequently, resulting in the soil being easily adhered to the side wall of the water guide pipe 8 or blocking the water outlet hole on the side wall of the water guide pipe 8. To this end, in this embodiment, a baffle 9 is provided to block the soil on the side surface of the water guide pipe 8, and the high-temperature steam drives the baffle 9 to rotate through the first fan blade 15 to stir the soil on the side wall of the water guide pipe 8, preventing the soil from continuously adhering to the outer wall of the water guide pipe 8. At the same time, the high-temperature steam drives the water guide pipe 8 to rotate through the second fan blade 16, further improving the cleaning effect of the baffle 9 on the soil on the side wall of the water guide pipe 8 and improving the spraying effect of the hot water.

[0040] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
