Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration, and in particular to a spraying device for grassland ecological soil restoration. Background Art

[0002] Grassland is one of the most important ecosystems on Earth, supporting a large number of plant and animal species and maintaining ecosystem diversity. The health of grassland soil is directly related to the stability of the grassland ecosystem, including vegetation growth, animal food chains, and microbial activities. When grassland soil is damaged, the balance of the entire ecosystem may be broken, leading to a series of problems such as decreased biodiversity, vegetation degradation, and soil erosion.

[0003] Grassland soil has good water retention capacity, can store and purify rainwater, and reduce soil erosion. Healthy grassland soil can slow down surface runoff and increase groundwater recharge, thereby protecting water resources. Once grassland soil is damaged, its water retention capacity will drop significantly, which may lead to water shortages and even natural disasters such as floods.

[0004] Prairie soil is one of the largest carbon storage reservoirs on Earth, capable of fixing large amounts of carbon dioxide, and plays an important role in mitigating climate change. By repairing prairie soil, its carbon storage capacity can be increased, reducing the concentration of carbon dioxide in the atmosphere, and thus combating global warming.

[0005] Grassland ecosystem is an important foundation for animal husbandry, and the restoration of grassland soil is crucial to restoring grassland productivity. Healthy grassland soil can provide abundant forage resources, ensure the development of animal husbandry, and thus ensure food security.

[0006] Nowadays, the spraying device used for grassland ecological soil restoration is generally equipped with a corresponding spraying mechanism on the vehicle body, and then the spraying mechanism uses high-pressure water flow or air flow to mix the soil restoration agent or other substances with the water flow or air flow to form a jet flow with a certain pressure and speed to spray the grassland soil surface; at the same time, some devices are inserted into the grassland soil through a nozzle of a special shape and inject the soil restoration agent. However, the soil barrenness in different areas of the grassland is different, and the hardness of the surface soil is different. When the hardness of the surface soil is high, it is difficult for the existing devices for spraying the grassland soil surface to quickly send the restoration liquid into the deeper soil, and the restoration liquids staying on the surface of the soil may evaporate quickly under the action of wind, thereby reducing the restoration efficiency, and for some devices that contact and insert the soil for injection restoration, the harder soil also causes greater loss to these insertion devices and greater difficulty in insertion. As for some operations that spray and repair the soil after turning the soil, the workload is large in terms of grassland soil restoration, and it takes a long time for these soils to return to the previous flat state after turning the soil, which is not conducive to the rapid restoration of grassland soil.

[0007] In summary, the present invention proposes a spraying device for grassland ecological soil restoration. When the soil on the grassland surface is high, it can not only complete the spray restoration of the grassland soil surface, but also can deeply penetrate the grassland soil to complete the injection of liquid medicine, thereby improving the effect of grassland soil ecological restoration. Summary of the invention

[0008] In order to solve the above problems, the present invention provides a spraying device for grassland ecological soil restoration. Through the cooperation and assistance between the lifting component, the spraying component and the injection component, when the surface soil of the grassland is relatively hard, the grassland soil surface can be sprayed for restoration. At the same time, the liquid medicine can also be injected deep into the grassland soil, thereby improving the effect of grassland soil ecological restoration.

[0009] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a spraying device for grassland ecological soil restoration, comprising a vehicle body, a booster frame is installed on the top of the vehicle body, a storage assembly for storing and transporting grassland ecological soil restoration liquid is installed on the top of the vehicle body, a lifting cavity is provided inside the vehicle body, a lifting assembly is provided inside the lifting cavity, a support plate is fixedly connected to the bottom of the lifting assembly, and a linear array at the bottom of the support plate has a plurality of spray assemblies for delivering liquid to the surface and deep layer of grassland ecological soil and located below the vehicle body; a pump assembly is provided inside the vehicle body; the spray assembly and the storage assembly are both connected to the pump assembly;

[0010] The injection components all include a rotating hole column fixedly connected to the bottom of the support plate, a spray ring for spraying repair liquid on the surface of grassland soil is arranged on the surface of the rotating hole column, and the top of the spray ring is fixedly connected to the bottom of the support plate, a plurality of injection ports connected to the storage component are arranged at the bottom of the spray ring, and a plurality of injection components for releasing repair liquid into the deep soil of grassland are arranged inside the rotating hole column.

[0011] Principle of the basic solution: The spraying device for grassland ecological soil remediation can be moved to the grassland area that needs to be repaired by carrying a booster frame and a storage component on the vehicle body. The storage component is used to store the grassland ecological soil remediation liquid and transport the liquid to the spraying component through the pump component. The spraying component includes a spray ring and an injection component located under the vehicle body, which can simultaneously deliver liquid to the surface and deep layer of grassland soil. The lifting component controls the lifting and lowering of the support plate and the spraying component, so that the spraying component can be accurately delivered close to the soil surface or deep into the soil.

[0012] The above scheme has the following beneficial effects: 1. Compared with some shortcomings of existing devices, such as single soil surface spraying and soil deep injection, soil turning and spraying, etc., the present invention uses a pump assembly to realize independent control of the injection ring and the injection assembly, so that not only can the appropriate drug administration method (soil surface spraying and soil deep injection) be selected according to the actual situation of grassland soil, but also the drug solution can be simultaneously delivered to the grassland soil surface and deep layer, thereby improving the effect and efficiency of soil remediation. Moreover, when the soil surface hardness in certain areas is high, the soil in these areas is sprayed by the injection ring to soften the surface soil, so that the injection assembly can be quickly penetrated into the soil layer through the lifting assembly to complete the injection of the drug solution. At the same time, after the injection assembly is lifted, the drug solution continuously released by the injection ring can also clean the injection assembly accordingly, reducing the possibility that the injection assembly is affected by excessive soil adhesion and normal use, and can also reduce the subsequent manual cleaning work, so that the device can work continuously for a long period of time, thereby improving the efficiency of grassland soil ecological restoration.

[0013] 2. This solution can adapt to soils of different heights through the adjustment of the lifting components, achieve precise delivery, and reduce the waste of liquid medicine.

[0014] Furthermore, the storage assembly includes a medicine storage tank fixedly connected to the top of the vehicle body, and the medicine storage tank is connected to the pump assembly.

[0015] Beneficial effects: The medicine storage tank is used to store a large amount of repair liquid, ensuring that the injection device can work continuously and improving work efficiency.

[0016] Furthermore, the lifting assembly includes a lifting column arranged in the lifting cavity, the bottom end of the lifting column extends through the lifting cavity to the bottom of the vehicle body and is fixedly connected to the top of the support plate, a plurality of teeth are provided on the surface of the lifting column along its axial direction, the teeth of the lifting column are meshed with a cam connecting rod rotatably connected to the inner wall of the lifting cavity, a first through groove is opened on the connecting rod surface of the cam connecting rod, a sliding column slidably matched with the cam connecting rod is provided in the first through groove, one end of the sliding column is fixedly connected to a circular rotating disk, a motor is embedded in the inner wall of the lifting cavity, and the output shaft of the motor is coaxially and fixedly connected to the center position of the rotating disk.

[0017] Beneficial effects: Through the rotation of the motor, the rotating disk and the sliding column are driven to slide in the first through groove of the cam connecting rod, and the cam connecting rod swings back and forth along the rotation center, thereby driving the lifting column engaged with the cam connecting rod to lift and lower, so as to achieve the smooth lifting and lowering of the injection assembly and the injection ring, and the lifting height is adjustable, and the adaptability is strong. At the same time, when the injection ring is close to some grassland soil surfaces with higher hardness, the impact force of the liquid medicine it receives will also increase as the injection ring approaches, thereby accelerating its softening efficiency, and then facilitating the subsequent injection assembly to penetrate into it and complete the repair work.

[0018] Furthermore, the connection point between the sliding column and the rotating disk is far away from the center of the rotating disk.

[0019] Beneficial effect: When the motor rotates, it can drive the rotating disk and the sliding column on the rotating disk, so that the sliding column as a whole rotates around the center of the rotating disk, thereby causing the sliding column to produce a larger displacement in the first through groove of the cam connecting rod, and pushing the cam connecting rod to swing back and forth, thereby realizing the rapid lifting and lowering of the lifting column to improve the efficiency of the repair work.

[0020] Furthermore, the injection components all include a telescopic chamber opened inside the rotating hole column and the telescopic chamber is inclined. A piston is provided in the telescopic chamber. One end of the piston is fixedly connected to a push rod that slides with the telescopic chamber. The push rod passes through the telescopic chamber away from the piston and extends obliquely downward to the outside of the rotating hole column and is hinged with a baffle. The top of the baffle is hinged to the rotating hole column and a torsion spring is provided at the hinge. An air inlet connected to the pump assembly is opened at one end of the telescopic chamber, and an air outlet connected to the pump assembly is opened at the other end of the telescopic chamber. The height of one end of the telescopic chamber close to the air inlet is higher than that of the other end. A plurality of spray outlets corresponding to the baffle and connected to the pump assembly are opened on the surface of the rotating hole column.

[0021] Beneficial effect: When the pump assembly injects gas into the telescopic chamber, the piston is pushed, which in turn pushes the push rod to move downward, and then the baffle is pushed to rotate through the push rod (that is, the baffle is away from the spray port), opening the spray port. At this time, the liquid medicine is sprayed out from the pump assembly through the spray port to achieve deep soil delivery.

[0022] Furthermore, one end of the piston connected to the push rod is fixedly connected to a spring surrounding the push rod, and one end of the spring away from the piston is fixedly connected to the inner wall of the telescopic cavity.

[0023] Beneficial effect: The setting of the spring enables the piston and the push rod to quickly reset after the gas pressure disappears, ensuring the normal operation of the injection assembly. When the pump assembly stops supplying gas and releases the previous high-pressure gas, it is connected to the outside world through the gas outlet to balance the gas pressure. At the same time, the piston and the push rod are reset under the action of the spring, and the baffle is also reset under the action of the torsion spring and the push rod, closing the spray port, thereby achieving accurate delivery and automatic control of the liquid medicine.

[0024] Furthermore, the baffles are all arc-shaped structures, and are embedded in the rotating hole column when the baffles are in the initial position.

[0025] Beneficial effects: The baffle with an arc structure can fit more smoothly on the rotating hole column, thereby increasing the sealing effect of the baffle on the spray port in the initial position and reducing the possibility of clogging of the spray port by debris. At the same time, when the baffle is expanded in the soil, a certain space will be formed, which is not only convenient for the subsequent injection of liquid medicine, but also can play a certain role in loosening the soil, so that the liquid medicine can quickly penetrate into the soil and diffuse around. For small lumps in the soil, the baffle can also play a role in crushing them to a certain extent when it is expanded, further improving the restoration efficiency of grassland soil ecology.

[0026] Furthermore, a rubber layer is provided on one side of the baffle plate close to the spray port.

[0027] Beneficial effects: The rubber layer can increase the sealing between the baffle and the spray port, prevent liquid leakage, and reduce the possibility of soil blocking the spray port. At the same time, the rubber layer can also play a buffering role, reducing the impact and noise when the baffle is turned over and reset.

[0028] Furthermore, an arc-shaped cleaning plate is installed on the vehicle body along the forward direction.

[0029] Beneficial effect: The cleaning plate can remove weeds, gravel and other obstacles on the soil surface when the vehicle body moves, so that some gravel moves along the arc surface to both sides of the vehicle body, ensuring that the injection assembly can smoothly contact the soil surface for liquid delivery.

[0030] Furthermore, a plurality of second through grooves are arranged in an array along the length direction of the cleaning plate at the bottom of the cleaning plate.

[0031] Beneficial effect: The provision of the second through groove can reduce the contact area between the cleaning plate and the soil, reduce friction, and enable the vehicle body to move more easily.

[0032] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The following is further described in detail through specific implementation methods:

[0044] Embodiment 1:

[0045] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown: A spraying device for grassland ecological soil restoration includes a vehicle body 1, a booster frame 3 is installed on the top of the vehicle body 1, and in order to ensure that the vehicle body 1 can provide sufficient thrust to reduce the manpower burden when moving on an uneven grassland, the booster frame 3 can be equipped with a hydraulic booster. A storage component for storing and transporting grassland ecological soil remediation liquid is installed on the top of the vehicle body 1, a lifting chamber 13 is arranged inside the vehicle body 1, a lifting component is arranged inside the lifting chamber 13, a support plate 6 is fixedly connected to the bottom of the lifting component, and a linear array at the bottom of the support plate 6 has several injection components for delivering liquid to the surface and deep layer of grassland ecological soil and located below the vehicle body 1; a pump component 4 is arranged inside the vehicle body 1; the injection component and the storage component are both connected to the pump component 4, and the pump component 4 is composed of an existing water pump and an air pump, so that the liquid in the medicine storage tank 2 is pressurized and transported to the injection ring 7 and the injection component through the water pump, and part of the movement of the injection component is controlled by the air pump, and in order to further improve the convenience of the device, the models of the water pump and the air pump are selected to be more intelligent, for example: the air pump selects the intelligent micro air pump V1500 series, and the water pump selects the powerful booster pump, so as to facilitate the subsequent independent control of the injection ring 7 and the injection component.

[0046] The injection components all include a rotating hole column 8 integrally formed at the bottom of the support plate 6, the surface of the rotating hole column 8 is ringed with a spray ring 7 for spraying repair liquid on the surface of the grassland soil, and the top of the spray ring 7 is integrally formed with the bottom of the support plate 6, and a plurality of injection ports 9 connected to the storage components are opened at the bottom of the spray ring 7, and a plurality of injection components for releasing the repair liquid into the deep soil of the grassland are arranged inside the rotating hole column 8.

[0047] The storage assembly includes a medicine storage tank 2 bolted to the top of the vehicle body 1 , and the medicine storage tank 2 is connected to the pump assembly 4 .

[0048] The lifting assembly includes a lifting column 14 arranged in the lifting chamber 13. The bottom end of the lifting column 14 extends through the lifting chamber 13 to the bottom of the vehicle body 1 and is bolted to the top of the support plate 6. A plurality of teeth are integrally formed on the surface of the lifting column 14 along its axial direction. The teeth of the lifting column 14 are meshed with a cam connecting rod 12 rotatably connected to the inner wall of the lifting chamber 13. A first through groove is opened on the connecting rod surface of the cam connecting rod 12. A sliding column 11 slidably matched with the cam connecting rod is provided in the first through groove. A circular rotating disk 10 is integrally formed at one end of the sliding column 11. A motor fixedly connected by screws is embedded in the lifting chamber 13. The output shaft of the motor is coaxially keyed with the center position of the rotating disk 10, and the connection between the sliding column 11 and the rotating disk 10 is away from the center of the rotating disk 10, thereby ensuring that the sliding column 11 can slide freely in the first through groove, so as to ensure the smoothness of the subsequent lifting of the lifting column 14 and improve the stability of the device.

[0049] The injection components all include a telescopic cavity 19 opened inside the rotating hole column 8, and the telescopic cavity 19 is inclined. A piston is slidably fitted in the telescopic cavity 19. One end of the piston is screwed to a push rod 17 that slidably fits with the telescopic cavity 19. The push rod 17 passes through the telescopic cavity 19 away from the end of the piston and extends obliquely downward to the outside of the rotating hole column 8 and is hinged with a baffle 15. The baffles 15 are all arc-shaped structures, and are embedded in the rotating hole column 8 when the baffles 15 are in the initial position. A rubber layer is bonded to the side of the baffle 15 close to the spray port 18 to enhance the sealing between the baffle 15 and the spray port 18 when the baffle 15 is closed, prevent leakage of the liquid medicine, and reduce the possibility of the soil blocking the spray port 18. In order to enable the baffle 15 to move with the push rod 17 and smoothly complete the opening and closing action, the hinge between the baffle 15 and the push rod 17 needs to slide with the baffle 15, that is, a slide groove is provided inside the baffle 15, and a slider is provided in the slide groove for hingedly connecting the push rod 17, so as to complete the movement process. At the same time, the inclined telescopic cavity 19 can enable the push rod 17 to push the baffle 15 in an oblique downward direction, so that the thrust received by the baffle 15 can be decomposed into two forces in the horizontal and vertical directions, thereby further accelerating the turning speed of the baffle 15 in the soil, and thus playing a certain role in loosening the soil.

[0050] The top of the baffle 15 is hinged on the rotating hole column 8 and a torsion spring is clamped at the hinge. An air inlet 16 connected to the pump assembly 4 is opened at one end of the telescopic cavity 19, and an air outlet connected to the pump assembly 4 is opened at the other end of the telescopic cavity 19. The air outlet and the air inlet 16 are connected through the pump assembly (air pump). When the above-mentioned intelligent air pump is used, the air pressure in the telescopic cavity 19 can be directly controlled by the air pump to complete the subsequent telescopic movement of the push rod 17; the end of the telescopic cavity 19 close to the air inlet 16 is higher than the other end, and the surface of the rotating hole column 8 is opened with a plurality of spraying ports 18 corresponding to the baffle 15 and connected to the pump assembly 4. The piston is fixedly connected to one end connected to the push rod 17 with a spring surrounding the push rod 17, and the end of the spring away from the piston is fixedly connected to the inner wall of the telescopic cavity 19.

[0051] The specific implementation process is as follows: when performing surface spraying and deep spraying, first start the pump assembly 4 (water pump), first the liquid medicine in the medicine storage tank 2 is transported to the injection port 9 of the injection ring 7 through the pipeline, and the liquid medicine sprayed from the injection port 9 is applied to the grassland soil surface. At the same time, the surface soil can also be softened during spraying to facilitate the subsequent deep spraying. For example, when the surface hardness of the grassland soil is high, it takes a long time for the rotary hole column 8 to be inserted into the target position to complete the subsequent injection work; then start the motor , the motor rotates to drive the rotating disk 10 and the sliding column 11 to move. When the sliding column 11 moves with the rotating disk 10, since the sliding column 11 is located in the first through slot of the cam connecting rod 12 and the cam connecting rod 12 is connected to the inner wall of the lifting chamber 13 in rotation, during the movement of the sliding column 11, it will slide along the first through slot and push the cam connecting rod 12 to swing back and forth along the rotation connection between it and the lifting chamber 13, so that the lifting column 14 engaged with the cam connecting rod 12 moves up and down, and then the hole-turning column 8 completes a series of processes of hole-turning-injection-lifting. And the above process can be completed by only rotating the motor in one direction, making the whole process more efficient and smooth, avoiding the time interval when the motor rotates forward and reverse, and further improving the efficiency of the overall repair work. After the surface soil softens, the lifting column 14 is controlled to lift and lower so that the support plate 6 and the rotating hole column 8 at the bottom gradually penetrate into the soil. After reaching a suitable position (e.g., the maximum descending distance), the pump assembly 4 (air pump) is started, and high-pressure gas is filled into the telescopic chamber 19 through the air inlet 16, so that the piston pushes the push rod 17 under the action of the air pressure, so that the push rod 17 pushes the baffle 15 to rotate along its hinge point, and the spray port 18 is opened. After the pump assembly 4 (water pump) is started, the medicine liquid is injected into the deep soil layer through the spray port 18. In order to facilitate management and reduce equipment costs, the spray port 18 and the injection port 9 can be different output parts connected to the same pump assembly 4 (water pump). When the medicine liquid is put into the telescopic chamber 19, the piston and the push rod 17 in the telescopic chamber 19 are reset to the initial position under the action of the spring, and the baffle 15 closes the spray port 18 under the action of the torsion spring and the push rod 17 to prevent the medicine liquid from continuing to flow out.

[0052] When only surface spraying is required, the bottom end of the rotating hole column 8 is placed at a suitable height, and the pump assembly 4 (water pump) is used to evenly spray the liquid medicine on the grassland soil surface through the injection port 9 at the bottom of the injection ring 7. For example, when the injection assembly is at a height of 10 cm from the soil surface, the liquid medicine is evenly sprayed on the soil surface through the multiple injection ports 9 at the bottom of the injection ring 7 to form a thin film of liquid medicine. For some grassland soil areas suitable for deep injection, the liquid medicine can be delivered to the spray port 18 alone after the rotating hole column 8 reaches the deep soil layer (such as 20 cm), so that the liquid medicine is injected into the soil about 20 cm deep.

[0053] Embodiment 2:

[0054] The difference from the first embodiment is that an arc-shaped cleaning plate 5 is installed on the vehicle body 1 along the forward direction, and a plurality of second through grooves arranged in an array along the length direction of the cleaning plate 5 are formed at the bottom of the cleaning plate 5 .

[0055] The specific implementation process is as follows: when the vehicle body 1 is traveling in the grassland, the bottom of the cleaning plate 5 will first contact or be close to the soil surface. When it contacts obstacles such as gravel, due to its arc design, these gravel will move along the arc surface of the cleaning plate 5 to both sides of the vehicle body 1, reducing the possibility that these obstacles will gather in front of the cleaning plate 5, thereby increasing the resistance to the subsequent movement of the vehicle body 1. If these obstacles are hit by components such as the rotating hole column 8, they may affect the effect and accuracy of the liquid medicine delivery. Therefore, the existence of the cleaning plate 5 greatly improves the accuracy and efficiency of the liquid medicine delivery.

[0056] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
