DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of 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.

[0038] Example 1: Please refer to Figure 1-Figure 5 and Figure 8-Figure 9 As shown, the existing irrigation device for tree breeding usually adopts a uniform fertilizer dosage for synchronous fertilization during the irrigation process, making it impossible to adjust the fertilizer dosage according to the growth conditions of different individuals. In order to solve this technical problem, this embodiment discloses the following technical contents;

[0039] A watering device for tree breeding comprises an infusion tube 1 connected to an infusion pump, a sleeve 3 is connected to the outside of the infusion tube 1, a branch pipe 5 is fixedly connected to the outside of the sleeve 3, and an irrigation pipe 7 is connected to the outside of the branch pipe 5;

[0040] The fixed plate 14 is fixedly installed on the outside of the branch pipe 5, and a fertilizer feeding component is arranged above the fixed plate 14, and a fixed component is rotatably installed on the top of the feeding component. At the same time, two groups of fixed components are spliced ​​and fixed on the outside of the trunk. The fixed component is controlled by the growth of the trunk to drive the fertilizer feeding component to perform telescopic adjustment, so as to realize automatic fertilizer delivery.

[0041] Drain holes 2 are evenly arranged at the upper end of the infusion tube 1, and the infusion tube 1 and the sleeve 3 form a sliding structure, and the two ends of the sleeve 3 are sealed and fit to the outer wall of the infusion tube 1. At the same time, the inner diameter of the middle part of the sleeve 3 is larger than the inner diameter of its two ends, and the water in the infusion tube 1 enters the inner side of the sleeve 3 through the drainage hole 2. The lower end of the sleeve 3 is fixedly connected to the positioning anchor 4, and the positioning anchor 4 is vertically inserted into the soil to support and fix the sleeve 3.

[0042] The fixing assembly includes an arc-shaped fixing frame 17 rotatably mounted on the top of the fertilizing assembly, and an adjusting bolt 18 is threadedly connected to the fixing frame 17, and an end of the adjusting bolt 18 close to the fixing frame 17 is rotatably connected to a telescopic cylinder 19, and the telescopic cylinder 19 is telescopically connected to the fixing frame 17, and a clamping assembly that fits the tree trunk is provided on the telescopic cylinder 19.

[0043] The clamping assembly includes a telescopic rod 21 elastically connected to the inner side of the telescopic tube 19 through a second spring 20, and an arc-shaped clamping plate 22 is fixedly connected to the end of the telescopic rod 21, and the clamping plate 22 is attached to the outer side of the tree trunk.

[0044] The fertilizer feeding assembly includes a telescopically connected fertilizer storage cylinder 15 and a support rod 16, and the lower end of the fertilizer storage cylinder 15 is rotatably connected to the outside of the fixed plate 14, and the upper end of the support rod 16 is rotatably connected to the bottom of the fixed frame 17. At the same time, the upper end of the fertilizer storage cylinder 15 is elastically rotatably connected to a positioning card 23, and the outer wall of the support rod 16 is evenly provided with positioning grooves 24, and the positioning card 23 and the positioning groove 24 are snap-fitted and connected.

[0045] A funnel-shaped partition 25 is evenly and fixedly connected to the inner side of the fertilizer storage cylinder 15, and granular fertilizer is stored above the partition 25, and the inner wall of the partition 25 is in contact with the outer wall of the support rod 16. At the same time, when the fertilizer storage cylinder 15 and the support rod 16 are telescopically adjusted, the fertilizer on each partition 25 is gradually released.

[0046] By adopting the above technical solution, when it is necessary to breed trees, the sleeve 3 is slid along the infusion tube 1 so that the irrigation pipe 7 outside the sleeve 3 is symmetrically distributed on the outside of the corresponding tree trunk, and then the positioning anchor 4 under the sleeve 3 is inserted into the soil to achieve positioning, and then the fertilizer storage barrel 15 is rotated so that the fixing frame 17 is close to the tree trunk, and the two fixing frames 17 are fixedly connected by bolts, and then the adjusting bolt 18 is rotated so that when the adjusting bolt 18 is screwed into the fixing frame 17, the telescopic barrel 19 is driven to be telescopically adjusted on the fixing frame 17, so that the splint 22 is fitted and clamped on the outside of the tree trunk. At this time, the fertilizer storage barrel 15 and the support rod 16 can cooperate with the fixing frame 17 to support the tree trunk, and as the tree trunk grows and becomes taller, the telescopic rod 21 will elastically move with the telescopic barrel 19. Telescopic adjustment can prevent the splint 22 from being embedded in the tree body due to the growth of the tree, thereby avoiding damage to the tree body. At the same time, during the growth of the tree, the support rod 16 will be pulled by the fixing frame 17, so that the fertilizer storage tube 15 and the support rod 16 can be telescopically adjusted. At the same time, the positioning clamp 23 will automatically fit into the positioning groove 24 at different heights to prevent the fertilizer storage tube 15 and the support rod 16 from automatically shrinking, thereby achieving effective support for the tree. During the rising process of the support rod 16, it will gradually move away from the partition 25 at different heights, so that the granular fertilizer above the partition 25 can automatically fall down and enter the blocking net 27 in the irrigation pipe 7 through the hose 26 for temporary storage, so as to facilitate dissolution and fertilization during the next irrigation process, so that the device can automatically add fertilizer according to the growth conditions of different individuals.

[0047] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. During the use of the existing watering device for tree breeding, the position of the watering port is fixed, so that the watering range and effect are limited. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 2 and Figure 6-Figure 8 As shown;

[0048] The connecting tube 6 is rotatably connected to the outer end of the branch tube 5, and the end of the connecting tube 6 away from the infusion tube 1 is fixedly connected to the irrigation tube 7, and a pressure valve assembly is arranged on the inner side of the branch tube 5, and a linkage assembly is arranged between the pressure valve assembly and the connecting tube 6 to drive the rotation of the connecting tube 6 and the irrigation tube 7; the pressure valve assembly includes a fixing ring 8 fixedly installed on the inner side of the branch tube 5, and a truncated cone-shaped sealing plug 9 is arranged on the inner side of the fixing ring 8, and a first spring 10 is connected between the sealing plug 9 and the fixing ring 8, and the sealing plug 9 is attached to the inner wall of the fixing ring 8 to realize For sealing the branch pipe 5, the linkage assembly includes a movable ring 11 fixedly installed on the outside of the sealing plug 9 through a frame, and a ball 12 is embedded in the outer wall of the movable ring 11, and the movable ring 11 is fitted to the inner wall of the connecting pipe 6. At the same time, the connecting pipe 6 and the movable ring 11 are coaxially arranged, and a spiral guide groove 13 is opened on the inner wall of the connecting pipe 6, and the ball 12 slides along the guide groove 13. Watering holes 701 are evenly opened on the watering pipe 7, and the watering pipes 7 are symmetrically distributed on both sides of the trunk, and the roots of the trunk are evenly irrigated through the watering holes 701 during the rotation of the watering pipe 7.

[0049] By adopting the above technical scheme, when irrigation is needed, the infusion pump is started, so that the infusion tube 1 transports water, and the water enters the inner side of the sleeve 3 through the drainage hole 2 and enters the branch pipe 5. When the water pressure inside the branch pipe 5 increases, the sealing plug 9 inside the fixed ring 8 will elastically expand and contract, so that the fixed ring 8 is opened, and then the water can enter the irrigation pipe 7 through the connecting pipe 6, and irrigate the root position of the tree through the irrigation hole 701. At the same time, during the movement of the sealing plug 9, the movable ring 11 will be driven by the bracket to slide back and forth on the inside of the connecting pipe 6. At this time, the ball 12 embedded in the outer wall of the movable ring 11 will slide along the spiral guide groove 13 opened on the inner wall of the connecting pipe 6, thereby driving the connecting pipe 6 to rotate back and forth. At this time, the irrigation pipe 7 can perform rotational spraying, which effectively expands the irrigation range, and the reciprocating rotation process can further promote the dissolution of the granular fertilizer pre-stored in the barrier 27, thereby achieving efficient irrigation and fertilization.
