Description

Technical Field

[0001] The invention relates to the technical field of gardening and greening, in particular to a fertilizing device for gardening and greening construction. Background Art

[0002] Gardening and greening refers to the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, through the transformation of terrain (or further building mountains, stacking stones, and managing water), planting trees, flowers, and plants, building buildings, and arranging garden paths. As the main body of the road greening system, street trees play a vital role in gardening and greening. They not only provide the necessary shade for the city, but also enrich the city's landscape and improve the city's ecological quality through their unique greening form.

[0003] The selection and configuration of street trees are crucial to the creation of road landscapes and the performance of ecological functions. They need to be able to adapt to the environmental conditions of the city, such as soil, climate, pollution, etc., and have certain ornamental and ecological values. At the same time, the planting and maintenance of street trees is also an important part of landscaping work, which requires professional technology and management.

[0004] In the existing roadside tree fertilization, the top of the drill pipe is connected to the liquid fertilizer injection mechanism, and the liquid fertilizer injection mechanism is connected to an injection pipe for conveying and supplying liquid fertilizer. When the drill pipe is transferred to the bottom of the roadside tree root, the injection pipe injects the liquid fertilizer into the tree root through the drill pipe. For example, the existing patent application number: CN202022100973.6 discloses: a soil deep fertilization device for tobacco planting;

[0005] However, the amount of nutrient solution required to be injected into the roots of each street tree is different, so it is impossible to accurately determine the specific amount of nutrient solution required. Therefore, the staff often hold the handle on the outside of the servo motor to rotate the drill pipe while moving it downward to inject the liquid, and then slowly pull the drill pipe out of the drill hole. During this process, on the one hand, the nutrient solution is easily splashed onto the legs and feet of the staff, causing a waste of nutrient solution. On the other hand, when the drill pipe is pulled out, a lot of soil and nutrient solution stick to the outside of the drill pipe, which affects the mobility and use of the drill pipe.

[0068] Specific implementation process: During landscaping construction, when deep fertilizing roadside trees, the staff only needs to push the support plate 3, and the multiple universal wheels 51 move in coordination, so as to move the support plate 3 to the desired fertilization position, and then lock the universal wheels 51 to ensure the support stability of the support plate 3;

[0074] Specific implementation process: before the drill pipe 1 moves downward, at this time, the output end of the first electric push rod 73 at the liquid guide cover 6 extends, so that the tapered block 74 moves along one end inside the connecting shell 72, and then the tapered block 74 pushes the two wedge blocks 751, and when it pushes the wedge block 751, the wedge block 751 drives the positioning rod 752 to move along the end away from the connecting shell 72, until the two clamping blocks 753 are respectively clamped in the clamping grooves 761, then the output end of the first electric push rod 73 stops moving, then at this time, the liquid guide cover 6 and the protective cover 2 They are fixed to each other, so that when the drill pipe 1 moves downward relative to the roots of the street trees, the liquid guide cover 6 moves downward synchronously. This arrangement not only saves energy consumption, but also ensures that the liquid guide cover 6 can move downward synchronously with the drill pipe 1. At the same time, when the liquid guide pipe is close to the ground, nine-tenths of the drill pipe 1 as a whole enters the soil, and liquid fertilizer is supplied through the liquid injection pipe 13 by the external liquid fertilizer feeding mechanism. Then, the liquid fertilizer is injected into the soil at the roots of the street trees through the drill pipe 1, and in this process, the liquid guide cover 6 can simultaneously play a role in protecting the liquid guide to prevent the liquid fertilizer from splashing.

[0080] Specific implementation process: when the drill pipe 1 stops moving downward and then moves upward, at this time, the rotating motor 448 rotates in the opposite direction, and it sends an electrical signal to the controller. At this time, the first electric push rod retracts, thereby disengaging the two clamping blocks 753 from the clamping groove 761, and at the same time, the second electric push rod 851 extends, so that the guide block 852 moves along the two positioning blocks 83. While moving, it pushes the two inclined blocks 853 through the inclination on both sides of the guide port 8521, so that the two positioning blocks 83 move toward each other until the semi-internal threaded sleeve 84 at the positioning block 83 is threadedly connected with the rotating screw 92. At this time, the liquid guide cover 6 does not move with the drill pipe 1, and the drill pipe 1 moves upward relative to the liquid guide cover 6. During the upward movement, the liquid guiding hood 6 can guide the sprayed liquid fertilizer on the one hand, and the liquid guiding block 61 at the liquid guiding hood 6 can scrape the liquid fertilizer and soil on the outside of the drill pipe 1 until the drill pipe 1 is completely separated from the liquid guiding hood 6, and then, the rotating motor 93 is operated to rotate the rotating screw 92, and while the rotating screw 92 rotates, it provides driving force for the two semi-inner threaded sleeves 84, and due to the limiting effect between the two positioning blocks 83 and the opening, the two positioning blocks 83 drive the liquid guiding hood 6 to move upward through the positioning shell 82 and the accommodating rod 81 until the liquid guiding hood 6 moves to the outside of the top of the drill pipe 1, at this time, liquid fertilizer is applied to the root of the next street tree.
