DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1-Figure 7, which is the first embodiment of the present invention, provides a fixed point watering device for flower borders, which can achieve the effect of automatically mixing and spraying liquid medicine during the watering process, and includes a watering component 100, including a main pipeline 101, a one-way valve 102 arranged on the main pipeline 101, a mixing rod 103 arranged on the inner wall of the main pipeline 101, a plurality of branch pipelines 104 arranged on the main pipeline 101, a plurality of rotating nozzles 105 arranged on the branch pipelines 104, and an extension pipe 106 arranged on the main pipeline 101; a medicine mixing component 200, including The main pipeline 101 includes a rotating component 201, a transmission component 202, a liquid adding component 203, and an elastic component 204. The regulating component 300 includes a switching component 301 disposed outside the main pipeline 101 and a blocking component 302 disposed on the transmission component 202. The anti-blocking component 400 includes a guide component 401 disposed on the transmission component 202 and a vibration component 402 disposed on the liquid adding component 203.

[0028] Specifically, the main pipe 101 is connected to water pressure. If the water pressure is insufficient, it can be pressurized by a water pump to ensure that the rotating nozzle 105 can rotate and spray, and the turbine blades 201b can rotate. The rotating nozzle 105 on the branch pipe 104 can be set to one or more, depending on the needs.

[0029] Furthermore, the rotating component 201 includes a telescopic rod 201a that passes through and is sealed and rotatably connected to the extension tube 106, the lower end of the telescopic rod 201a is fixedly connected to a turbine blade 201b, the telescopic end of the telescopic rod 201a is completely outside the extension tube 106, a backup motor 201c is fixedly connected to the side wall of the extension tube 106, the output shaft of the backup motor 201c passes through the main pipe 101 and is rotatably connected to the main pipe 101, and the output shaft of the backup motor 201c is fixedly connected to the telescopic rod 201a; the transmission component 202 includes a first gear 202a fixedly connected to the telescopic rod 201a, a mounting seat 202b is fixedly connected to the main pipe 101, a transmission shaft 202c is rotatably connected to the mounting seat 202b, and a second gear 202d meshing with the first gear 202a is fixedly connected to the transmission shaft 202c.

[0030] The telescopic end is completely outside the extension tube 106 to avoid water leakage when the telescopic end is extended or retracted. The backup motor 201c can be used as a backup power in the case of insufficient water pressure to ensure that the telescopic rod 201a can rotate.

[0031] Preferably, the liquid adding assembly 203 includes an installation box 203a fixedly connected to the main pipeline 101, a first liquid adding pipe 203b is fixedly connected to the installation box 203a, a second liquid adding pipe 203c connected to the main pipeline 101 is provided at the lower side of the first liquid adding pipe 203b, a storage bucket 203d is fixedly connected to the first liquid adding pipe 203b, a plurality of circular grooves 203e with different diameters are provided in the storage bucket 203d, a disc 203f is provided between the first liquid adding pipe 203b and the second liquid adding pipe 203c, and the second gear 202d is fixedly connected to the disc 203f through a connecting shaft. The disc 203f is provided with a plurality of circular openings 203g which cooperate with the first liquid-adding tube 203b and the second liquid-adding tube 203c; the elastic component 204 includes a mounting tube 204a fixedly connected to the second liquid-adding tube 203c, a circular ring 204b is slidably connected inside the mounting tube 204a, the circular ring 204b is elastically connected to the inner wall of the mounting tube 204a through a first spring 204c, a U-shaped rod 204d is fixedly connected to the circular ring 204b, a pressure plate 204e is fixedly connected to the U-shaped rod 204d, and a friction pad 204f is fixedly connected to the lower end surface of the pressure plate 204e.

[0032] It should be noted that the outer end of the second liquid adding tube 203c extends to the outside of the installation box 203a, the distance between the second liquid adding tube 203c and the first liquid adding tube 203b is equal to the thickness of the disc 203f, and a sealing gasket is provided on the contact surface of the first liquid adding tube 203b, the second liquid adding tube 203c and the disc 203f to ensure that sealing can be achieved when the disc 203f rotates.

[0033] When in use, water with water pressure enters the main pipeline 101, and the water will push the turbine blades 201b to rotate, so that the telescopic rod 201a rotates, driving the first gear 202a to rotate, thereby causing the second gear 202d meshing with the first gear 202a to rotate, and driving the disc 203f to rotate through the connecting shaft. When the disc 203f rotates, the multiple round openings 203g are constantly changing positions, intermittently facing the first liquid adding pipe 203b and the second liquid adding pipe 203c. When the round opening 203g is facing the first liquid adding pipe 203b and the second liquid adding pipe 203c, the liquid in the storage bucket 203d can enter the main pipeline 101 through the first liquid adding pipe 203b and the second liquid adding pipe 203c, and then be mixed with water and sprayed out through the rotating nozzle 105 on the branch pipe 104. The setting of the mixing rod 103 here can make the hydrated liquid mix more fully, so as to achieve the effect of spraying medicine during irrigation, and when applying medicine (this The medicine in refers to liquid fertilizer, herbicide, pesticide, etc., the same below), pull the U-shaped rod 204d to make the U-shaped rod 204d move upward, drive the ring 204b to move upward, the first spring 204c stretches, and then put the bottle containing the liquid medicine into the storage bucket 203d. The setting of multiple circular grooves 203e here can be suitable for most liquid medicine bottles. After the liquid medicine bottle is placed, release the U-shaped rod 204d. Under the action of the first spring 204c, the ring 204b is reset and drives the U-shaped rod 204d to reset, so that the pressure plate 204e moves downward to squeeze the liquid medicine bottle. The setting of the friction pad 204f can avoid relative sliding between the liquid medicine bottle and the pressure plate 204e, thereby completing the medicine application. It is worth noting that after the medicine in the medicine bottle is used up, do not immediately close the main pipeline 101 to prevent part of the liquid medicine from remaining in the branch pipeline 104 and affecting the next spraying of other medicines. The setting of the one-way valve 102 here avoids backflow.

[0034] In summary, by setting up the watering component 100 and the medicine mixing component 200, while the rotating nozzle 105 rotates for watering, the water pressure can also be used to make the medicine bottle in the storage hopper intermittently deliver the medicine liquid into the main pipeline 101, and the rotating nozzle 105 sprays it after mixing, thereby achieving the effect of spraying medicine while watering.

[0035] Example 2, reference Figure 2-Figure 7, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a control component 300 of a fixed point watering device for a flower border, which solves the problem of how to control the speed of adding liquid medicine and how to avoid wear between the first liquid adding pipe 203b, the second liquid adding pipe 203c and the disc 203f when no liquid is added. It includes a switching component 301, including an annular groove 301a arranged on the telescopic end of the telescopic rod 201a, and a slider 30 is slidably connected to the inner wall of the installation box 203a in the annular groove 301a. 1b, a threaded rod 301c is threadedly connected to the slider 301b, and a support shaft 301d is fixedly connected to the threaded rod 301c, and the support shaft 301d passes through the installation box 203a and is sealed and rotatably connected to the installation box 203a; the blocking component 302 includes a cover plate 302a rotatably connected to the installation box 203a, and a plurality of plugs 302b are arranged in the circular opening 203g, and the heights of the plurality of plugs 302b are all smaller than the height of the circular opening 203g, and the lower end surfaces of the plurality of plugs 302b are fixedly connected to T-shaped blocks 302c.

[0036] Specifically, the cover plate 302a here can also be provided with a lock to prevent the cover plate 302a from opening automatically. The lower end of the T-shaped block 302c here will not go over the disc 203f, thereby preventing the T-shaped block 302c from getting stuck with the second liquid adding tube 203c when the disc 203f rotates. A turntable is fixedly connected to the support shaft 301d here to facilitate the rotation of the support shaft 301d.

[0037] During use, when there is no need to add liquid, the support shaft 301d can be rotated to rotate the threaded rod 301c, so that the slider 301b moves downward, and the slider 301b cooperates with the annular groove 301a to drive the telescopic rod 201a to contract. At this time, the first gear 202a and the second gear 202d are separated to avoid the second gear 202d still rotating when there is no need to add liquid, causing wear between the disc 203f, the first liquid adding tube 203b, and the second liquid adding tube 203c. When it is necessary to control the speed of adding liquid, it is only necessary to open the cover plate 302a and then insert the plug 302b into The plug 302b can be inserted into the circular mouth 203g. A plurality of plugs 302b are provided in the installation box 203a here, so that they can be directly taken out when needed. At the same time, the plug 302b here has an interference fit with the circular mouth 203g. After being inserted into the circular mouth 203g, the plug 302b will not fall off. When the plug 302b is inserted into the circular mouth 203g, when the disc 203f rotates one circle, the conduction time between the first liquid adding tube 203b and the second liquid adding tube 203c can be reduced, thereby changing the speed of adding the liquid medicine (in actual use, the dosage ratio only needs to be approximate, and does not need to be completely accurate).

[0038] In summary, by setting the regulating component 300, on the one hand, it is possible to adjust whether the first gear 202a and the second gear 202d are engaged, thereby avoiding continued wear between the disc 203f, the first liquid adding tube 203b, and the second liquid adding tube 203c when no liquid is needed. At the same time, the number of conductive circular openings 203g is adjusted, the conductive time between the first liquid adding tube 203b and the second liquid adding tube 203c is changed, and the speed of adding liquid medicine is changed. It can be suitable for different types of liquid medicine and is more widely used.

[0039] Example 3, reference Figure 2-Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-blocking component 400 of a fixed point watering device for a flower border, which solves the problem of preventing the medicine bottle from being blocked when adding medicine powder (insecticide powder, etc.). It includes a guide component 401, including a plurality of first arc grooves 401a arranged on a disc 203f, and the plurality of first arc grooves 401a are all connected to a second arc groove 401b, and the second arc groove 401b is provided with a vertical groove 401c, and the vertical groove 401c is connected to a third arc groove 401d, and the first arc groove 401a, the second arc groove 401b, the vertical groove 401c and the third arc groove 401d are connected to each other. The groove 401d is a group, and the third arc groove 401d is connected to the first arc groove 401a of the adjacent group; the vibration component 402 includes a first impact block 402a fixedly connected to the first liquid adding tube 203b, a bar frame 402b is fixedly connected to the first liquid adding tube 203b, a moving block 402c is slidably connected in the bar frame 402b, a guide rod 402f matching the second arc groove 401b is fixedly connected to the moving block 402c, the moving block 402c is elastically connected to the inner wall of the bar frame 402b through a second spring 402d, and a second impact block 402e that collides with the first impact block 402a is fixedly connected to the moving block 402c.

[0040] Specifically, here multiple groups of first arc grooves 401a, second arc grooves 401b, vertical grooves 401c and third arc grooves 401d are continuously arranged around the disc 203f, and the first impact block 402a and the second impact block 402e collide to generate vibration. Here, the moving block 402c is completely located at the lower side of the first impact block 402a, so that when the first impact block 402a and the second impact block 402e collide, the moving block 402c will not resist and block the second impact block 402e.

[0041] When in use, during the rotation of the disc 203f, the first arc groove 401a first cooperates with the guide rod 402f, at which time the guide rod 402f does not move. When the second arc groove 401b cooperates with the guide rod 402f, it can drive the guide rod 402f to move outward, thereby the moving block 402c moves outward, and the second spring 402d is compressed, so that the first impact block 402a and the second impact block 402e slowly move away from each other. When the vertical groove 401c is directly opposite to the guide rod 402f, under the action of the second spring 402d, the guide rod 402f is quickly reset, and the moving block 402c is quickly reset, so that the first impact block 402a quickly hits the second impact block 402e to generate vibration, and the vibration is transmitted to the medicine bottle through the first liquid adding pipe 203b and the feeding hopper, so as to realize the vibration of the medicine bottle, thereby avoiding the phenomenon that the powder blocks the bottle mouth when the added material is in powder form, causing the material to be unable to be discharged. Then the third arc groove 401d and the guide rod 40 2f cooperates, at this time the guide rod 402f does not move, here the first arc groove 401a, the second arc groove 401b, the vertical groove 401c and the third arc groove 401d are arranged in multiple groups, so that as the disk 203f rotates, the medicine bottle vibrates continuously to avoid blockage of the powder medicine. It is worth noting that the second spring 402d here is elastic enough. When the guide rod 402f is in the vertical groove 401c, although the disk 203f will also have a tendency to rotate, the guide rod 402f and the side wall of the vertical groove 401c are against each other, but because the guide rod 402f is in point contact and the second spring 402d is elastic enough, it is ensured that the guide rod 402f can be pulled back. When the backup motor 201c is used to provide power, the backup motor 201c can be briefly paused when the guide rod 402f enters the vertical groove 401c. The backup motor 201c can be controlled by a program. This is the prior art and will not be elaborated here.

[0042] In summary, by setting the anti-clogging component 400, during the rotation of the disc 203f, the first impact block 402a and the second impact block 402e can intermittently collide to generate vibration, and the vibration is transmitted to the medicine bottle through the first liquid adding pipe 203b and the adding hopper, causing the medicine bottle to vibrate, so that when powdered medicine is added, it is not easy for powder to clog the bottle mouth.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
