Description

Technical Field

[0001] This utility model relates to the field of landscaping technology, and in particular to a fertilization device for garden trees. Background Technology

[0002] Landscape greening is the creation of beautiful natural environments and recreational areas within a specific region through engineering techniques and artistic methods. This involves modifying the terrain, constructing hills, stacking rocks, managing water features, planting trees and flowers, building structures, and arranging garden paths. Landscape greening enhances the aesthetics of a city and purifies its air. Trees are a crucial component of landscape greening. To ensure better tree growth and improve survival rates, meticulous care and management by landscape workers are essential. This includes fertilizing, watering, and loosening the soil. Fertilization involves applying appropriate fertilizers based on the characteristics and growth needs of different trees. Currently, landscape workers typically use shovels to dig trenches near the tree roots, spread fertilizer in the trenches, and then backfill the soil. This method is labor-intensive and inefficient in practice. Utility Model Content

[0003] The technical problem this utility model aims to solve is that in the existing technology, gardeners generally use shovels to dig up the soil near the roots of trees, then spread fertilizer in the excavated trenches, and then backfill the soil. In actual operation, this is labor-intensive and has low fertilization efficiency.

[0004] To address the aforementioned problems, this utility model provides a garden tree fertilization device, comprising an outer cylinder and an inner cylinder that slide and nest together. The lower end of the outer cylinder is rotatably provided with two semi-conical inserts. The upper end of the inner cylinder is connected to a storage box via a flexible hose. The outer edge of the lower end of the inner cylinder abuts against the inner wall of the semi-conical inserts. When the inner cylinder slides along the outer cylinder toward the semi-conical inserts, the two semi-conical inserts can open relative to each other.

[0005] The garden tree fertilization device provided by this utility model also has the following technical features:

[0006] A torsion spring is provided between the outer cylinder and the semi-conical insert.

[0007] The inner cylinder is provided with a flange at the upper end for connection with a hose, and a compression spring is also fitted on the inner cylinder, which is located between the flange and the outer cylinder.

[0008] Multiple pressure bars are spaced apart on the outer circumference of the flange.

[0009] The lower end of the inner cylinder is integrally formed with a top ring, the outer wall of which is arc-shaped and abuts against the inner wall of the semi-conical insert.

[0010] The outer cylinder is provided with a handle at the top.

[0011] This invention has the following advantages: The semi-conical insert at the bottom of the outer cylinder is inserted into the soil, and the inner cylinder is controlled to slide along the outer cylinder toward the semi-conical insert. The contact and pushing cause the two semi-conical inserts to rotate to open relative to each other, so as to form a fertilizer placement space in the soil. The fertilizer enters the inner cylinder through the storage box and the hose and enters the fertilizer placement space. Then the inner cylinder is reset so that the two semi-conical inserts rotate to close relative to each other. The semi-conical inserts are then pulled out of the soil to complete the fertilization, reducing labor intensity and improving fertilization efficiency. Attached Figure Description

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 As shown, the garden tree fertilization device of this utility model includes an outer cylinder 11 and an inner cylinder 12 that slide and nest together. The lower end of the outer cylinder 11 is rotatably provided with two semi-conical inserts 13. The upper end of the inner cylinder 12 is connected to the storage box 15 through a hose 14. The outer edge of the lower end of the inner cylinder 12 abuts against the inner wall of the semi-conical inserts 13. When the inner cylinder 12 slides along the outer cylinder 11 toward the semi-conical inserts 13, the two semi-conical inserts 13 can open relative to each other.

[0017] Insert the semi-conical insert 13 at the bottom of the outer cylinder 11 into the soil. Control the inner cylinder 12 to slide along the outer cylinder 11 toward the semi-conical insert 13. The contact and pushing cause the two semi-conical inserts 13 to rotate to open relative to each other, so as to form a fertilizer placement space in the soil. The fertilizer enters the inner cylinder 12 through the storage box 15 and the hose 14 and enters the fertilizer placement space. Then, reset the inner cylinder 12 so that the two semi-conical inserts 13 rotate to close relative to each other. Finally, pull the semi-conical inserts 13 out of the soil to complete the fertilization, reduce labor intensity and improve fertilization efficiency.

[0018] Among them, see Figure 3When closed, the semi-conical insert 13 can be folded into a conical shell for easy insertion into the soil. Its thickness and material can be selected to ensure sufficient strength. Hinge seats are provided at the upper end of the semi-conical insert 13 and the lower end of the outer cylinder 11, allowing the semi-conical insert 13 to rotate and be positioned at the lower end of the outer cylinder 11, with the hinge seats located in the middle of the semi-conical insert 13. Furthermore, due to the hinge seats, a gap exists between the outer cylinder 11 and the semi-conical insert 13. To prevent soil or debris from entering, a dustproof plate 10, made of a soft material such as rubber, is provided between the outer cylinder 11 and the semi-conical insert 13.

[0019] Among them, see Figure 1 The storage box 15 is preferably a backpack with straps so that gardeners can carry it. The top of the storage box 15 is provided with a feeding port for adding fertilizer. The bottom of the interior can also be provided with a stirring device to prevent the fertilizer from clumping and affecting the entry into the hose 14 and the application of fertilizer. The size and material of the hose 14 can be selected to avoid affecting the operation of gardeners.

[0020] Preferably, see Figure 3 A torsion spring 16 is provided between the outer cylinder 11 and the semi-conical insert 13.

[0021] As a structural variation, magnetic layers may be provided on the sides of the two semi-conical inserts 13 that are close to each other, so that the two semi-conical inserts 13 have a tendency to rotate to close.

[0022] Preferably, the upper end of the inner cylinder 12 extends out of the outer cylinder 11 and is provided with a flange 17 for connection with the hose 14. A compression spring 18 is also fitted on the inner cylinder 12. The compression spring 18 is located between the flange 17 and the outer cylinder 11. Under the action of the compression spring 18, the outer edge of the lower end of the inner cylinder 12 abuts against the inner wall of the semi-conical insert 13, and at the same time, the inner cylinder 12 can be reset.

[0023] Preferably, a plurality of pressure rods 19 are spaced apart on the outer circumferential surface of the flange 17, and the pressure rods 19 are pressed to make the inner cylinder 12 slide along the outer cylinder 11 toward the semi-conical insert shell 13.

[0024] Preferably, the lower end of the inner cylinder 12 extends out of the outer cylinder 11 and is integrally formed with a top ring 20. The outer wall of the top ring 20 is arc-shaped and abuts against the inner wall of the semi-conical insert shell 13.

[0025] Preferably, the upper part of the outer cylinder 11 is provided with a handle 21.

[0026] The working principle of this utility model is as follows:

[0027] Holding handle 21, insert the semi-conical insert 13 at the bottom of the outer cylinder 11 into the soil. Press the pressure rod 19 to make the inner cylinder 12 slide along the outer cylinder 11 toward the semi-conical insert 13. At the same time, the pressure spring 18 is compressed, and the two semi-conical inserts 13 rotate to open relative to each other, so as to form a fertilizer placement space in the soil. The fertilizer enters the inner cylinder 12 through the storage box 15 and the hose 14 and enters the fertilizer placement space. Release the pressure rod 19, and the pressure spring 18 makes the inner cylinder 12 slide away from the semi-conical insert 13 to reset. The two semi-conical inserts 13 rotate to close relative to each other under the action of the torsion spring 16. Then pull the semi-conical insert 13 out of the soil to complete the fertilization, reduce labor intensity and improve fertilization efficiency.
