Description

Technical Field

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

[0002] Mine restoration, also known as mine ecological restoration, is the restoration of pollution in mining wasteland. In recent years, the research on mine ecological restoration has developed rapidly, and the ecological reclamation of mining land has gradually been carried out. The most important thing for mine restoration is the restoration and protection of mine vegetation. In the process of restoring and protecting mine vegetation, it is necessary to water the vegetation, fertilize it, and spray pesticides. In order to improve work efficiency and reduce labor costs, modern spraying devices are widely used in watering and fertilizing (mainly liquid fertilizers).

[0003] However, in the existing mine restoration methods, especially in the fertilization or watering of vegetation, there are problems of missed watering or missing fertilization, and even problems of over-watering or over-fertilization, which affect the growth of vegetation; and the reason for these problems is that the layout of the injection device is unreasonable and the mine terrain is not taken into consideration. At the same time, the injection range of the existing injection device is limited, and the injection capacity of the injection device cannot be adjusted according to the terrain.

[0004] For example, during spraying, it is impossible to spray different areas according to the elevation angle of the spray pipe. At the same time, during the spraying process, it is impossible to rotate the spray pipe around itself to spray in multiple directions around the spray pipe. For example, a spraying device for mine greening recorded in patent number "CN217742572U" and a vegetation spraying device for mine restoration recorded in patent number "CN216146942U" cannot simultaneously realize the change of the elevation angle of the spray pipe and the rotation of the spray pipe around itself to realize spraying in multiple positions. If you want to achieve a combination of the two, you can only operate it by holding the spray pipe, which is time-consuming and labor-intensive. Summary of the invention

[0005] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a mine repair method and a spraying device. The present invention is applied to mines after sowing vegetation to achieve full coverage of mine vegetation with watering or fertilizing, providing a more favorable growth environment for mine vegetation.

[0006] In a first aspect, the present invention provides a mine restoration method, which is applied to a mine after vegetation is sown, comprising:

[0007] Collecting data of mines planted with vegetation, wherein the mine data includes area information and terrain information of the vegetation in the mines;

[0008] Determine the number of injection devices and injection installation points according to the mine data and the injection range of the injection devices;

[0009] Determine the location of the central supply source based on the injection installation points of all injection devices;

[0010] According to the injection installation point and the central supply source position, the injection device and the supply box are installed respectively. The injection device includes a temporary storage box. On both sides of the temporary storage box, there are spray units with independent injection and adjustable elevation angles. The temporary storage box is connected to a transmission mechanism that drives the temporary storage box and the injection unit to rotate. The temporary storage box is connected to the supply box, and the liquid enters the temporary storage box from the supply box and is then sprayed to the designated area through the injection unit;

[0011] Controlling the spraying device to spray liquid for promoting vegetation growth, the liquid being water or nutrient solution;

[0012] Regularly check the growth of vegetation in the mine and determine whether to continue controlling the injection device to inject the liquid.

[0013] Through the above-mentioned technical means, the injection device can be reasonably arranged according to the vegetation area, terrain and injection capacity of the mine, so as to achieve full coverage of the vegetation; at the same time, two independent injection units are reasonably designed on the injection device, and the injection unit can independently adjust the elevation angle and change the injection range, and the injection unit can also rotate, which can effectively expand the injection range.

[0014] Optionally, the method of controlling the spraying device to spray the liquid that promotes vegetation growth is:

[0015] The spraying posture of the spraying device is adjusted according to the terrain information, and the spraying posture includes the elevation angle of the spraying unit, the rotation angle or the rotation speed of the temporary storage box,

[0016] After receiving the liquid spraying command, the spraying device that has completed the spraying posture adjustment starts the liquid spraying pump and the liquid is sprayed out from the spraying head;

[0017] When the liquid in the temporary storage tank is insufficient, the spray pump stops working and the liquid in the supply tank is replenished into the temporary storage tank. When the liquid in the temporary storage tank is sufficient, the spray pump continues to work until the spraying time or spraying amount reaches the specified value, and then stops spraying.

[0018] The above technical means utilizes the terrain to adjust the spray elevation angle of the spray device so that its liquid can be better sprayed into the designated area, and adjusts the rotation angle or rotation speed of the spray device to expand the spray range of the spray unit, thereby achieving full coverage of mine vegetation with watering or fertilizing.

[0019] Optionally, the method of regularly checking the growth of vegetation in the mine and determining whether to continue controlling the injection device to inject the liquid is:

[0020] Acquire spraying requirement information of the spraying area, wherein the spraying requirement information at least includes vegetation growth conditions, soil moisture conditions and soil compaction conditions;

[0021] When the injection demand information reaches a set first standard, maintaining the current injection amount and injection time of the injection unit;

[0022] When the injection demand information reaches a set second standard, reducing the injection amount of the injection unit or / and shortening the injection time;

[0023] When the injection requirement information reaches a set third standard, the injection unit stops working.

[0024] The first standard, the second standard and the third standard are jointly determined based on vegetation growth conditions, soil moisture conditions and soil compactness conditions.

[0025] This technical means can reasonably adjust the injection flow of the injection device, reduce the waste of the liquid, and reduce the impact of too much or too little liquid on vegetation growth, because too much or too little liquid may affect the growth of vegetation, and too much liquid can easily make the mine soil looser and easier to lose.

[0026] In a second aspect, the present invention provides a spraying device for the above-mentioned mine restoration method, comprising:

[0027] Fixed bracket,

[0028] A temporary storage box is rotatably mounted on the fixed frame, the temporary storage box is connected to a liquid inlet pipe, and the other end of the liquid inlet pipe is connected to the supply box;

[0029] A transmission mechanism, installed in the fixing frame and connected to the temporary storage box, driving the temporary storage box to rotate; and

[0030] Two groups of spray units are respectively installed on the front side and the rear side of the temporary storage box through a protective box. The spray units are hinged to the protective box, and an adjustment mechanism for adjusting the elevation angle of the spray units is arranged inside the protective box.

[0031] The above technical means can change the elevation angle of the injection unit and rotate the injection unit itself, thereby increasing the injection range, and can be controlled by an external control system during injection to reduce manual operation and reduce operating difficulty.

[0032] In order to adjust the elevation angle of the injection unit, optionally, the injection unit includes

[0033] A liquid spray pump is arranged in the temporary storage box;

[0034] Connecting pipe A, one end of which is connected to the spray pump, and the other end of which passes through the temporary storage box into the protection box and is fixed to the temporary storage box through the mounting plate;

[0035] A connecting pipe B, one end of which is connected to the connecting pipe A, and the outer side of the other end is fixed to the inner side of the protection box through a fixing rod;

[0036] Two support plates are arranged opposite to each other on the inner side of the opening end of the protection box;

[0037] A rod body is arranged between two supporting plates;

[0038] An injection pipe passes through the opening of the protection box and keeps the outer end hinged on the rod body;

[0039] an injection head, disposed at the end of the injection pipe at the outer end of the protection box; and

[0040] One end of the connecting pipe C is connected to the injection pipe, and the other end is installed with the end of the connecting pipe B through a bearing seal.

[0041] The above technical means not only facilitates changing the elevation angle of the spray pipe so that the spray pipe can spray to a farther or closer position, but also combines rotation to facilitate the spray pipe to rotate around the temporary storage box, facilitating overall spraying of the outside of the temporary storage box, which can effectively expand the spray range.

[0042] Optionally, the connecting pipe B and the connecting pipe C are connecting pipes formed by connecting a plurality of straight pipes with right-angle elbows, and the connecting portion of the connecting pipe B and the connecting pipe C is arranged coaxially with the rod body.

[0043] This technical solution is achieved by providing two right-angle bend connecting pipes, the ends of which are connected by bearings. At the same time, the installation position of the bearings and the hinge position of the injection pipe are on the same axis. In this way, when the injection pipe adjusts its elevation angle, the bearings on the connecting pipes can facilitate the injection pipe to rotate around the hinge point to adjust the elevation angle while always keeping the injection pipe connected to the temporary storage box, avoiding the problem of the hose possibly falling off when connected.

[0044] Optionally, the adjustment mechanism is a linear telescopic member with adjustable extension length, one end of which is hinged to the top of the protective box above the spray pipe, and the other end is hinged to the end of the spray pipe away from the spray head. This technical solution realizes the adjustment of the spray pipe elevation angle, and can be adjusted independently.

[0045] Optionally, the transmission mechanism includes a first motor and a driving gear, and the first motor drives the gear shaft where the driving gear is located to rotate through a belt transmission structure. A gear ring is connected to the bottom center of the temporary storage box through multiple connecting columns, and the gear ring and the driving gear are meshed with each other. This technical means can realize the rotation of the temporary storage box, thereby adjusting the rotation angle or rotation speed of the injection pipe, and expanding the injection range of the injection device.

[0046] Optionally, a stirring vane is eccentrically arranged in the temporary storage box, and the stirring vane is driven to rotate by a second motor arranged at the outer end of the temporary storage box. This technical means can achieve the stirring of the liquid and ensure that the ejected liquid is uniform. The eccentric arrangement of the stirring vane can cause the liquid to move irregularly in the temporary storage box, so that the solute is dissolved more evenly in the solution, and the precipitation of the solute is reduced.

[0047] The present invention has the following advantages:

[0048] The present invention provides a mine restoration method and a spraying device, which can achieve full coverage of watering or fertilizing of mine vegetation, and provide a more favorable growth environment for mine vegetation. The provided spraying device is not only convenient for changing the elevation angle of the spraying pipe, so that the spraying pipe can spray to a farther or closer position, but also combined with rotation, it is convenient for the spraying pipe to rotate around the temporary storage box, and it is convenient to spray the outside of the temporary storage box as a whole, which can effectively expand the spraying range. In addition, the spraying device is combined with a control system to realize automated operation, reduce the intensity of manual operation, and avoid the staff from being wetted by the rotating spraying pipe when standing by the side to operate.

DETAILED DESCRIPTION

[0064] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0065] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0066] A mine repair method and a spraying device according to an embodiment of the present application are described below with reference to the accompanying drawings. It is mentioned in the above background technology that in the existing mine repair methods, especially the fertilization or watering of vegetation, there are problems of missed watering or missed fertilization, and even problems of over-watering or over-fertilization, which affect the growth of vegetation. The reason for these problems is that the layout of the spraying device is unreasonable and the mine terrain is not taken into consideration. At the same time, the spraying range of the existing spraying device is limited, and the spraying capacity of the spraying device cannot be adjusted according to the terrain.

[0067] Based on the above reasons, the present invention provides a mine repair method, such as Figure 1 Shown is a schematic flow chart of the mine restoration method.

[0068] In step S100, data of mines planted with vegetation are collected, and the mine data include area information and terrain information of the mine vegetation, and the terrain information includes at least terrain undulation, terrain inclination direction and trend; wherein the method for collecting the area information of the mine vegetation is to obtain it from the previous planting plan, and the method for collecting the terrain information is to obtain it by using existing remote sensing technology (obtaining terrain data through satellites, aviation, remote sensing instruments, etc.) or field collection methods (obtaining it through manual measurement, GPS measurement, etc.) or obtaining it from existing topographic maps.

[0069] In step S200, the number of injection devices and injection installation points are determined according to the mine data and the injection range of the injection device;

[0070] Exemplarily, the number of injection devices is determined by the following formula:

[0071]

[0072] Where: N is the number of injection devices, S is the area information of mine vegetation, δ is the area adjustment coefficient, is the terrain adjustment factor, The value range of is [0.8,1.2], the value range of δ is [0.8,1.3], and the specific values ​​of ∅ and δ are determined by the staff according to the actual situation.

[0073] The purpose of introducing the area adjustment coefficient δ is to adjust the area of ​​vegetation in irregular areas, because some irregular areas only need to install one spray device, but after calculation according to the actual area, two spray devices need to be installed; for example, vegetation in strip-shaped areas only needs one spray device after area calculation, but because the area is strip-shaped and the length is too long, one spray device cannot cover it at all.

[0074] Introducing terrain adjustment factors The purpose is to solve the problem of liquid flow direction caused by terrain undulation, terrain inclination direction and trend, because the terrain inclination direction and terrain undulation will affect the liquid flow direction; the terrain undulation will cause the liquid flow to be trapped, and additional injection devices are required; while the terrain inclination direction and trend will promote liquid flow, and it is only necessary to increase the injection flow rate to pour the vegetation that goes with the flow, without the need for additional injection devices, and the number of injection devices can be appropriately reduced.

[0075] After determining the number of the above-mentioned injection devices, the staff marked the required injection installation points according to the map.

[0076] In step S300, the position of the central supply source is determined based on the injection installation points of all injection devices; the position of the central supply source is confirmed by a map marked with the injection installation points, and the central supply source is ensured to be located in the central position as much as possible. If one supply source is not enough, additional central supply sources can be appropriately added to increase the position of the central supply source.

[0077] In step S400, according to the injection installation point and the central supply source position, the injection device and the supply box are installed respectively, the injection device includes a temporary storage box, and injection units with independent injection and adjustable elevation angles are installed on both sides of the temporary storage box, the temporary storage box is connected to a transmission mechanism that drives the temporary storage box and the injection unit to rotate, the temporary storage box is connected to the supply box, the liquid enters the temporary storage box from the supply box, and then is injected into the designated area through the injection unit; the injection unit is individually controlled, and its injection flow rate and injection distance can be adjusted, so that the injection distance of the injection unit on one side can be greater than or less than the injection distance of the injection unit on the other side, thereby covering more vegetation and increasing the coverage area of ​​pouring.

[0078] In step S500, the spraying device is controlled to spray a liquid that promotes vegetation growth, and the liquid is water or a nutrient solution;

[0079] Exemplary methods of controlling the spraying device to spray the liquid that promotes vegetation growth are:

[0080] The spraying posture of the spraying device is adjusted according to the terrain information, and the spraying posture includes the elevation angle of the spraying unit, the rotation angle or the rotation speed of the temporary storage box,

[0081] After receiving the liquid spraying command, the spraying device that has completed the spraying posture adjustment starts the liquid spraying pump and the liquid is sprayed out from the spraying head;

[0082] When the liquid in the temporary storage tank is insufficient, the spray pump stops working and the liquid in the supply tank is replenished into the temporary storage tank. When the liquid in the temporary storage tank is sufficient, the spray pump continues to work until the spraying time or spraying amount reaches the specified value, and then stops spraying.

[0083] In step S600, the growth of vegetation in the mine is checked regularly, and it is determined whether to continue controlling the injection device to inject the liquid.

[0084] Exemplarily, the method of regularly checking the growth of vegetation in the mine and determining whether to continue controlling the injection device to inject the liquid is:

[0085] The spraying requirement information of the spraying area is obtained, and the spraying requirement information at least includes vegetation growth conditions, soil moisture conditions and soil compaction conditions.

[0086] The vegetation growth conditions are analyzed and judged by the staff of the mine and the vegetation in the corresponding area, and are divided into the growth reaching standard stage, the growth deficiency stage and the stable growth stage.

[0087] The soil moisture condition is determined by the relative soil moisture of the corresponding area, and the relative soil moisture (R) refers to the percentage of soil water content to field water holding capacity, and soil moisture content = water weight / dry soil weight × 100%; when R>60%, the corresponding area is in a state of sufficient water, when 40<R≤60, the corresponding area is in a state of almost sufficient water, and when R≤40, the corresponding area is in a state of water shortage.

[0088] The soil compaction condition is determined by the staff according to the soil compaction of the corresponding area. The greater the soil compaction, the more unfavorable it is for vegetation growth. At this time, it needs to be moisturized with appropriate water, or the staff can solve it manually. The soil compaction condition can be divided into loose soil state, normal soil state, and over-tight soil state. When the soil in the corresponding area is in a loose soil state, it is not necessary to pour water, because continuous pouring of water is prone to soil erosion; when the soil in the corresponding area is in a normal soil state, a small amount of water can be poured to meet the growth of vegetation; when the soil in the corresponding area is in an over-tight soil state, it is necessary to pour an increased amount of water. Using this water to alleviate the over-tight soil state can also meet the growth of vegetation.

[0089] When the injection demand information reaches a set first standard, maintaining the current injection amount and injection time of the injection unit;

[0090] When the injection demand information reaches a set second standard, reducing the injection amount of the injection unit or / and shortening the injection time;

[0091] When the injection requirement information reaches a set third standard, the injection unit stops working.

[0092] The first standard is that the vegetation growth is in a growth deficiency stage, or the soil moisture is in a water deficiency state, or the soil compactness is in a soil over-compact state;

[0093] The second standard is that the vegetation growth is in a stable growth stage, the soil moisture is in a state of being nearly sufficient, or the soil compaction is in a normal state;

[0094] The third standard is that the vegetation growth condition is at the growth standard stage, the soil moisture condition is in a water-sufficient state, or the soil compaction condition is in a loose soil state.

[0095] In this embodiment, the mine restoration method can reasonably arrange the injection device according to the vegetation area, terrain and injection capacity of the mine, so as to achieve full coverage of the vegetation; at the same time, two independent injection units are reasonably designed on the injection device, and the injection unit can independently adjust the elevation angle to change the injection range, and the injection unit can also rotate to effectively expand the injection range; by reasonably adjusting the injection flow of the injection device, the waste of the liquid is reduced, and at the same time, the impact of too much or too little liquid on the growth of the object is reduced, because too much or too little liquid can affect the growth of vegetation, and too much liquid can also make the mine soil looser and easier to lose.

[0096] In another embodiment, the present invention provides a spraying device for the above-mentioned mine restoration method, such as Figure 2-Figure 5 As shown, the spray device specifically includes a fixed frame 1, a temporary storage box 4, two groups of spray units and a liquid inlet pipe 3, and a transmission mechanism is arranged inside the fixed frame 1; the temporary storage box 4 is arranged on the fixed frame 1 and keeps the temporary storage box 4 rotating around itself through the transmission mechanism; there are two groups of spray units, and the two groups of spray units are respectively installed on the front side and the rear side of the temporary storage box through a protective box, and are symmetrically arranged; the spray unit adjusts its elevation angle through an adjustment mechanism arranged in the protective box 5.

[0097] By means of the above arrangement, the spray unit can be rotated and the elevation angle adjusted to expand the spray range of the spray device.

[0098] The liquid inlet pipe 3 is arranged in the fixing frame 1 and one end of the liquid inlet pipe 3 is inserted into the temporary storage box 4, and the other end of the liquid inlet pipe 3 is connected to the supply box.

[0099] The supply box makes it convenient for the staff to add nutrient solution or water to the spray device in time, and can also solve the problem of the traditional water adding method causing the staff to get wet; the traditional water adding method requires the spray device to be stopped. If water is added directly without stopping the work, the staff will get wet or even injured due to the rotation of the spray device.

[0100] Meanwhile, through holes are provided at the four corners of the fixing frame 1 , and the through holes are provided to facilitate the passage of the rod body deep underground, thereby improving the stability of the fixing frame 1 .

[0101] In some embodiments, Figure 6-Figure 8As shown, the transmission mechanism includes a first motor 2 and a driving gear 11. The first motor 2 drives the gear shaft where the driving gear 11 is located to rotate through a belt transmission structure.

[0102] In this embodiment, a gear ring 12 is connected to the bottom center of the temporary storage box 4 through a plurality of connecting columns 13 , and the gear ring 12 and the driving gear 11 are meshed with each other.

[0103] The temporary storage box can be rotated by setting a gear transmission method to facilitate automatic control. Other automatic control methods can also be used to rotate the temporary storage box, such as by adding a chain at the bottom of the temporary storage box and rotating an external sprocket to engage with the chain, which can also drive the temporary storage box to rotate.

[0104] like Figure 6 and Figure 7 As shown, in some embodiments, a plurality of balls 10 are further arranged above the fixing frame 1, and the balls 10 are distributed in a circle. The temporary storage box 4 is placed on the balls 10, and a ring 14 is arranged at the bottom end of the temporary storage box 4 and is clamped on the outer end of the balls 10.

[0105] This structural feature is that it is easy to support the temporary storage box and can be rotated at the same time. Figure 8 In the structure shown, a large wheel disc 25 is provided at the bottom of the temporary storage box and the top of the fixed frame 1, respectively. Grooves are provided on the opposite surfaces of the two wheel discs and balls (similar to thrust ball bearings) are provided in the grooves, which can support the temporary storage box without affecting the rotation of the temporary storage box.

[0106] like Figure 6 As shown, in some embodiments, a placement tube 9 coaxial with the gear ring 12 is further provided in the fixing frame 1, and a connecting hole is provided at the outer end of the placement tube 9. The end of the liquid inlet pipe 3 passes through the connecting hole and enters the placement tube 9, then extends upward and keeps the end connected with the temporary storage box 4 and connected through a bearing (a bearing seal or other mechanical sealing structure needs to be added during the connection to prevent liquid leakage in the temporary storage box 4).

[0107] The placement cylinder is provided to facilitate fixing the liquid inlet pipe, so as to prevent the liquid inlet pipe from entering the meshing position of the gear ring and the driving gear when the placement water tank is rotated, thereby causing the liquid inlet pipe to break.

[0108] In some embodiments, Fig. 9 As shown, a stirring vane 15 is eccentrically arranged in the temporary storage box 4 , and the stirring vane 15 is driven to rotate by a second motor 6 arranged at the outer end of the temporary storage box 4 .

[0109] The stirring blade can be set to an eccentric structure, which can improve the quality of stirring.

[0110] As shown in this figure, the temporary storage box 4 and the protective box are composed of a shell and a plate body arranged at the open end of the shell. The shell and the plate body are combined and sealed to form a temporary storage box and a protective box, which makes it easy to install stirring blades and injection units in the temporary storage box and the protective box.

[0111] In some embodiments, Figure 10-13 As shown, each group of the spraying units includes a spraying pump 16, which is arranged in the temporary storage box 4;

[0112] A connecting pipe A17, one end of which is connected to the spray pump 16, and the other end of which passes through the temporary storage box 4 into the protection box 5 and is fixed to the temporary storage box 4 through the mounting plate 18;

[0113] A connecting pipe B19, one end of which is connected to the connecting pipe A17, and the outer side of the other end is fixed to the inner side of the protection box 5 through a fixing rod 21;

[0114] Two support plates 23 are arranged opposite to each other on the inner side of the opening end of the protection box 5;

[0115] The rod body 24 is arranged between the two support plates 23;

[0116] The spray pipe 7 passes through the opening of the protection box 5 and keeps the outer end hinged on the rod body 24;

[0117] A spray head 8 is provided on the end of the spray pipe 7 at the outer end of the protection box 5; and

[0118] One end of the connecting pipe C20 is connected to the injection pipe 7, and the other end is connected to the end of the connecting pipe B19 through a bearing.

[0119] Since the conventional connection method between the spray pipe and the temporary storage box is through a hose, and the connection method between the hose and the hard pipe is a pipe clamp connection or a hose sleeve on the outer end of the hard pipe, when the spray pipe is adjusted in elevation, the hose is pulled or rotated, which is very easy to fall off, thereby causing the spray pipe to separate from the temporary storage box. In order to solve the problem that the spray pipe and the temporary storage box are easy to fall off, in some embodiments, the connecting pipe B19 and the connecting pipe C20 are connecting pipes of multiple straight pipes and right-angle elbows, and the connecting part of the connecting pipe B19 and the connecting pipe C20 is coaxial with the rod body 24. This setting method can ensure that the spray pipe and the temporary storage box are connected through a hard pipe, avoiding the problem of the hose easily falling off when connected.

[0120] In some embodiments, the adjustment mechanism is a linear telescopic member 22 with adjustable extension length, one end of which is hinged to the top of the protective box 5 above the injection pipe 7; and the other end is hinged to the end of the injection pipe 7 away from the injection head 8.

[0121] The linear telescopic member can be a cylinder, an electric push rod, etc. In order to achieve adjustable extension length, a three-position five-way cylinder can be used. The adjustable stroke of the cylinder and the electric push rod is well known and will not be described in detail here.

[0122] When the spraying device is in use, the fixing frame 1 is first placed flat on the plane of the mine and the rod body passes through the through hole of the fixing frame 1 and penetrates into the ground to fix the fixing frame 1. After installation, the staff can stay away from this position to facilitate the subsequent spraying operation of the spraying unit. The linear telescopic member 22 is first started to extend or retract to the extreme position through the external control system to keep the elevation angle of the spray pipe 7 to the maximum or minimum. The external water pump is started through the external control system to supply liquid to the liquid inlet pipe 3, and the liquid passes through the liquid inlet pipe 3 into the temporary storage box 4, and then the second motor 6 is started to drive the stirring vane 15 to stir the liquid in the temporary storage box 4 so that the liquid is fully mixed. The spray pump 16 is started through the control system, and the spray pump 16 sucks the liquid in the temporary storage box 4 into the connecting pipe A17, and then passes through the connecting pipe B19 and the connecting pipe C20 into the spray pipe 7, and finally sprays out from the spray head 8 for spraying operation. During the spraying process, the control system starts the first motor 2 to rotate, driving the driving gear 11 to rotate, and the ring gear 12 at the bottom of the temporary storage box 4 is meshed with the driving gear 11, thereby driving the temporary storage box 4 and the spray units on both sides to rotate around the center of the temporary storage box 4 to expand the spraying range. After the ring gear 12 rotates for a fixed time (i.e., the ring gear rotates half a circle), the control system controls the linear telescopic member 22 to retract or extend a certain length, driving the spray pipe 7 to rotate a certain angle around the rod body 24, that is, to adjust the elevation angle of the spray pipe 7, and then after the ring gear 12 rotates for a fixed time, the control system controls the linear telescopic member 22 to retract or extend again until it reaches the limit position, completing the spraying operation, and then closing each driving member.

[0123] The selection of bearings, seals, gears, motors and other models in this technical solution can refer to the 2019 edition of the textbook "Fundamentals of Mechanical Design". The control system in this technical solution can refer to "Principles of Automatic Control" published by Tsinghua University Press or other books and reference documents in the field. Other automatic control devices not mentioned (such as cylinders, electric push rods, etc.) are all knowledge well known to those skilled in the art and will not be repeated here.

[0124] The spray device is not only convenient for changing the elevation angle of the spray pipe so that the spray pipe can spray to a farther or closer position, but also combined with rotation, it is convenient for the spray pipe to rotate around the temporary storage box, which is convenient for the overall spraying of the outside of the temporary storage box, and can effectively expand the spray range. In addition, the spray device can be combined with an external control system to realize automated operation, reduce the intensity of manual operation, and avoid the staff from being wetted by the rotating spray pipe when standing by the side to operate.

[0125] The technical solution sets up spray units on both sides of the temporary storage box. The two spray units are arranged symmetrically. When the spray units on both sides spray liquid at the same time, they can offset a part of the reaction force (the reaction force is generated when spraying liquid) to improve the stability of the entire device during the spraying process.

[0126] In order to solve the problem that the injection pipe is easily detached from the temporary storage box when connected with the hose, the technical solution provides two connecting pipes in the form of right-angle bends. The ends of the two connecting pipes are connected by bearings. At the same time, the installation position of the bearing and the hinge position of the injection pipe are on the same axis. In this way, when the injection pipe adjusts the elevation angle, the bearing on the connecting pipe can facilitate the injection pipe to rotate around the hinge point to achieve elevation adjustment while always keeping the injection pipe connected to the temporary storage box, avoiding the problem of the hose possibly falling off when connected.

[0127] In order to facilitate the stirring of the sprayed water or nutrient solution, the technical solution eccentrically sets a stirring rotor in the temporary storage box, so as to facilitate the uniform stirring of the medicine or nutrient solution and then spray it out through the spray unit.
