[0016] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] For the embodiments of the present invention, please refer to Figure 1-Figure 9A multi-angle sprinkler irrigation device for landscape gardening includes a cart 1, a liquid storage tank 2 is arranged on the surface of the cart 1, a liquid inlet 3 is opened on the surface of the liquid storage tank 2, a bidirectional motor 4 is arranged on the top of the liquid storage tank 2, two groups of multi-angle spraying structures 5 are arranged on both sides of the bidirectional motor 4, the two groups of multi-angle spraying structures 5 include at least two swing plates 56 and a guide pipe 57, two groups of cutting structures 6 are arranged on the side of the two groups of multi-angle spraying structures 5 away from the bidirectional motor 4, the two groups of cutting structures 6 include at least two cutting knives 61, and the two groups of cutting structures 6 are respectively arranged on the outermost side of the cart 1; The multi-angle spraying structure 5 rotates the swing plate 56 and the guide tube 57 to swing and spray the nutrient solution, and at the same time drives the cutting knife 61 to cut the redundant branches, and the cutting knife 61 can guide and protect the nutrient solution sprayed from the guide tube 57.

[0018] First of all, why do we need to carry out multi-angle sprinkler irrigation in the garden? This is because the distribution of trees in the garden is not completely regular. They may be scattered at different heights and have different planting densities. Multi-angle sprinkler irrigation can adjust the angle and position of the sprinkler to ensure that every plant can get enough water, whether in the edge area or in the center area of ​​the garden. For example, in a garden with undulating terrain, if only a single angle is used to sprinkle water for plants in high and low places, it may cause water shortage for plants in high places. Multi-angle sprinkler irrigation can solve this problem, making the water fall evenly in various areas like drizzle, thereby improving the efficiency of sprinkler irrigation and reducing the waste of resources. Among them, considering the multi-angle sprinkler irrigation process of the garden, the applicant found that when the existing multi-angle sprinkler device encounters extra branches for sprinkler irrigation, the extra branches will cause damage to the sprinkler head, which affects the service life of the sprinkler head. As for why the sprinkler head is damaged, it is because the extra branches will exceed the position of the sprinkler head. At this time, when the sprinkler head is swinging at multiple angles, the extra branches will collide with the multi-angle swinging sprinkler head, causing the sprinkler head to be damaged or affecting its service life. If the extra branches are not cut, it will also affect the subsequent walking of people and even cause harm to people. Therefore, the multi-angle spraying structure 5 is driven to swing the swing plate 56 and the guide tube 57, so that the nutrient solution can be sprayed at multiple angles, and the swing plate 56 drives the cutting knife 61 to swing and cut the branches that are not in contact with the nutrient solution at the same time, which not only reduces the extra branches from being distributed to the nutrient solution, but also can divert the nutrient solution sprayed from the guide tube 57 through the cutting knife 61, and protect the guide tube 57 from being impacted and contacted by extra branches to reduce the service life of the guide tube 57; Secondly, considering that when the garden encounters windy and rainy weather during the multi-angle sprinkler irrigation process, the branches will be blown by the wind and affect the subsequent cutting of the cutting knife 61 or fail to cut quickly, resulting in reduced cutting efficiency, and when the guide tube 57 sprays nutrient solution, the external wind will blow away the sprayed nutrient solution, resulting in the nutrient solution cannot be accurately sprayed on the branches. Therefore, the excess branches are diverted to the inside of the liquid storage tank 2 through the liquid storage tank 2, and then the cutting knife 61 swings to cut the excess branches. On the one hand, it is to prevent the branches from shaking in windy and rainy weather, which makes the cutting knife 61 unable to cut quickly. On the other hand, it is to block the nutrient solution sprayed from the guide tube 57 to prevent the external wind from blowing away the sprayed nutrient solution and failing to spray it accurately on the required branches. It can not only adapt to work in windy and rainy weather but also reduce the waste of resources.

[0019] The following is a specific structure to implement the above-mentioned problems: First, you need to drain the nutrient solution to the location where it needs to be sprayed. Please refer to Figure 2-Figure 5 The multi-angle spraying structure 5 at least includes a liquid absorbing ball 571, which is fixedly connected to the bottom of the guide tube 57, and is arranged inside the liquid storage tank 2. A stirring blade 572 is fixedly connected to the surface of the guide tube 57. A micro water pump is arranged inside the liquid absorbing ball 571. First, the staff needs to open the liquid inlet 3 to pour the nutrient solution into the liquid storage tank 2, and then remotely control the micro water pump inside the liquid absorbing ball 571 through the remote control to start, so that the liquid absorbing ball 571 generates suction and sucks the nutrient solution into the guide tube 57, so that the nutrient solution can be sprayed out from the subsequent sprinkler head; As for the working principle of the micro water pump, it is mainly based on the circular motion of the motor. Through mechanical devices, the diaphragm or impeller inside the water pump makes reciprocating or rotational motion, thereby compressing and stretching the air in the pump chamber, forming positive pressure and vacuum, and then generating a pressure difference to suck in and discharge water. Specifically, the micro water pump usually includes a motor, a diaphragm, a one-way valve and other components. The motor drives the diaphragm or impeller to move. The reciprocating motion of the diaphragm compresses the air in the pump chamber. The function of the one-way valve is to form a positive pressure at the drain port and a vacuum at the water suction port, thereby generating a pressure difference with the external atmospheric pressure to achieve water suction and discharge. This process continues under the action of the kinetic energy transmitted by the motor to form a stable flow rate, thereby facilitating the suction of the nutrient solution into the guide tube 57.

[0020] Next, to realize multi-angle spraying of nutrient solution, the structure of multi-angle spraying structure 5 needs to be disclosed in detail, please refer to Figure 2-Figure 8The multi-angle spraying structure 5 at least includes a rotating shaft 51, which is fixedly connected to the output end of the bidirectional motor 4, and a rotating disk 52 is fixedly connected to the end of the rotating shaft 51 away from the bidirectional motor 4, and a side of the rotating disk 52 away from the rotating shaft 51 is fixedly connected to a limiting column 53, and a sliding column 54 is rotatably connected to the surface of the limiting column 53, and a limiting shaft 55 is slidably connected inside the sliding column 54, and both ends of the limiting shaft 55 are fixedly connected to two swing plates 56, and the side of the two swing plates 56 away from the limiting shaft 55 is fixedly connected to the guide pipe 57, and a liquid spray head 573 is fixedly connected to the surface of the guide pipe 57; Two L limit plates 58 are rotatably connected at both ends of the guide tube 57, and a limit plate 59 is fixedly connected between the two L limit plates 58. The rotating shaft 51 passes through the inside of the limit plate 59, and the bottom of the L limit plate 58 is fixedly connected to the liquid storage tank 2. When the nutrient solution is sucked into the guide tube 57, the staff remotely controls the bidirectional motor 4 to start again, so that the rotating shaft 51 rotates, and the rotation of the rotating shaft 51 drives the rotating disk 52 to rotate synchronously. Please refer to the following specific movement process Figure 4 and Figure 6 At this time, since the limiting post 53 is arranged at the farthest point from the center of the rotating disk 52, and the limiting post 53 is rotatably connected to the sliding post 54, when the rotating disk 52 rotates forward, the limiting post 53 will be driven to rotate to the rightmost side around the center of the rotating disk 52. At the same time, when the limiting post 53 rotates to the rightmost side of the rotating disk 52, the rotatably connected sliding post 54 will be driven to synchronously rotate to the rightmost side around the center of the rotating disk 52. Since the sliding post 54 is slidably connected to the limiting shaft 55, when the sliding post 54 rotates to the rightmost side around the center of the rotating disk 52, it will pull the limiting shaft 55. The shaft 55 swings when the sliding column 54 rotates to the rightmost direction. As for why the limiting shaft 55 swings when the sliding column 54 rotates to the rightmost direction, it is because the two ends of the limiting shaft 55 are fixedly connected to the two swing plates 56, and the two swing plates 56 are internally penetrated and fixedly connected with the guide tube 57, and the guide tube 57 is rotatably connected to the L limiting plate 58. Therefore, when the limiting shaft 55 is pulled to the rightmost direction of the sliding column 54, it will synchronously drive the swing plate 56 and the guide tube 57 to rotate inside the L limiting plate 58, so that the limiting shaft 55, the swing plate 56 and the guide tube 57 can swing. Next, when the rotating disk 52 continues to rotate, it will drive the limiting column 53 and the sliding column 54 on the right side to rotate to the leftmost side of the rotating disk 52, so that the limiting shaft 55, the swing plate 56 and the guide tube 57 swing from the rightmost side to the leftmost side (the principle is opposite to the above description), thereby realizing reciprocating swing. At the same time, when the guide tube 57 swings back and forth, it will drive the spray head 573 to swing, so that the nutrient solution sucked into the guide tube 57 is sprayed out from the spray head 573, and the spray head 573 can swing at multiple angles to spray the nutrient solution, and when the guide tube 57 swings back and forth, it will also drive the stirring blade 572 to swing, so that the stirring blade 572 stirs the nutrient solution inside the liquid storage tank 2 to prevent the nutrient solution from solidifying after standing for a long time.

[0021] Then, it is necessary to cut off the excess branches when spraying the nutrient solution. The cutting structure 6 at least includes a cutting knife 61. The cutting knife 61 is fixedly connected to the swing plate 56. A guide port 62 is provided in the middle of the cutting knife 61. A wind shield 63 is provided on the outside of the cutting knife 61. The wind shield 63 is detachably mounted on the surface of the cart 1. When the swing plate 56 swings back and forth, it will synchronously drive the cutting knife 61 to swing, so that the cutting knife 61 can cut off the excess branches. At the same time, the spray head 573 swings synchronously with the guide port 62, so it does not affect the spray head 573 spraying the nutrient solution. When the spray head 573 sprays the nutrient solution, the cutting knife 61 can also guide the nutrient solution and protect the spray head 573. This is because the cutting knife 61 can wrap the spray head 573. Please refer to Figure 6 and Figure 7 , thereby increasing the service life of the liquid ejection head 573.

[0022] Next, when the whole device encounters windy and rainy weather, the following specific states and parts settings need to be disclosed to facilitate understanding of the working principle below. The sliding distance of the sliding column 54 on the surface of the limit shaft 55 is the same as the rotation range of the rotating disk 52. The swing plates 56 fixed at both ends of the limit shaft 55 are adapted to the guide tube 57. The inside of the guide tube 57 is through-set. There are multiple groups of fixed liquid spray heads 573 on the surface of the guide tube 57. The two L-shaped limit plates 58 rotatably connected at both ends of the guide tube 57 are L-shaped. The limit plate 59 fixed between the two L-shaped limit plates 58 is used to support the rotation of the rotating shaft 51. The range of the guide port 62 of the cutting blade 61 is the same as that of the multiple groups of spray heads 573. The swinging force of the cutting blade 61 is sufficient to cut the branches, and the nutrient solution sprayed by the spray head 573 is controllable. Because one end of the swing plate 56 is rotatably connected to the limit shaft 55, and the other end is fixedly connected to the guide tube 57, and the cutting knife 61 is fixedly connected to the swing plate 56, therefore, when the limit shaft 55 is at the rightmost position, the swing plate 56 and the guide tube 57 fixed at both ends of the limit shaft 55 are swinging to the left, and when the swing plate 56 is at the leftmost position, the cutting knife 61 fixedly connected to the swing plate 56 is in the process of cutting branches on the left side, and when the limit shaft 55 is at the leftmost position, the swing plate 56 and the guide tube 57 fixed at both ends of the limit shaft 55 are swinging to the right, and when the swing plate 56 is at the rightmost position, the cutting knife 61 fixedly connected to the swing plate 56 is in the process of cutting branches on the right side. When encountering windy and rainy weather, please refer to Fig. 9 The excess branches will first contact the wind shield 63 and pass over the wind shield 63, so that the excess branches are inside the wind shield 63, and then the cutting knife 61 can cut the excess branches when it swings back and forth, so that the branches are cut inside the wind shield 63. The reason why the excess branches need to be cut inside the wind shield 63 is to prevent the external wind from blowing the excess branches, so that the cutting knife 61 cannot cut quickly or the cutting knife 61 cannot cut them all at once. At the same time, the nutrient solution sprayed by the spray head 573 can also pass through the wind shield 63 to block the wind, so that the sprayed nutrient solution can be sprayed normally to the surface of the branches, thereby improving the efficiency of sprinkler irrigation.

[0023] Working principle: First, the staff needs to open the liquid inlet 3 to pour the nutrient solution into the liquid storage tank 2, and then remotely control the micro water pump inside the liquid absorption ball 571 through the remote control to start, so that the liquid absorption ball 571 generates suction and absorbs the nutrient solution into the guide tube 57. When the nutrient solution is absorbed into the guide tube 57, the staff remotely controls the bidirectional motor 4 to start again, so that the rotating shaft 51 rotates. The rotation of the rotating shaft 51 will drive the rotating disk 52 to rotate synchronously, and synchronously drive the limit column 53 and the sliding column 54 to rotate. At the same time, the sliding column 54 will pull the limit shaft 55 to swing, and then synchronously drive the swing plate 56 and the guide tube 57 to rotate inside the L limit plate 58, so as to realize the swing of the limit shaft 55, the swing plate 56 and the guide tube 57; Next, when the rotating disk 52 continues to rotate, the reciprocating swing of the flow guide tube 57 drives the liquid spray head 573 to swing, so that the nutrient solution sucked into the flow guide tube 57 is sprayed out from the liquid spray head 573, and the liquid spray head 573 can swing at multiple angles to spray the nutrient solution, and the flow guide tube 57 swings back and forth and drives the stirring blade 572 to swing, so that the stirring blade 572 stirs the nutrient solution inside the liquid storage tank 2 to prevent the nutrient solution from solidifying after being left still for a long time. When the swing plate 56 swings back and forth, it will synchronously drive the cutting blade 61 to swing, so that the cutting blade 61 can cut the redundant branches. At the same time, the liquid spraying head 573 swings synchronously with the diversion port 62, so it does not affect the spraying of nutrient solution by the liquid spraying head 573. When the liquid spraying head 573 sprays nutrient solution, the cutting blade 61 can also divert the nutrient solution and protect the liquid spraying head 573, thereby increasing the service life of the liquid spraying head 573. When encountering windy and rainy weather, please refer to Fig. 9 The excess branches will first contact the wind shield 63 and pass over the wind shield 63, so that the excess branches are inside the wind shield 63, and then the cutting knife 61 can cut the excess branches when it swings back and forth, so that the branches are cut inside the wind shield 63. At the same time, the nutrient solution sprayed by the spray head 573 can also pass through the wind shield 63 to block the wind force, so that the sprayed nutrient solution can be sprayed normally to the surface of the branches, thereby improving the efficiency of sprinkler irrigation.
