Description

Technical Field

[0001] The invention relates to the technical field of municipal gardens, and in particular to an environmentally friendly planting device for municipal gardens. Background Art

[0002] The municipal garden project belongs to the garden. But it includes two parts: municipal engineering and garden engineering. Municipal engineering includes underground pipes, roads, pavement, etc.; garden engineering includes greening, garden pieces, and garden roads. Garden engineering mainly studies the engineering technology of garden construction, including earthwork engineering for terrain transformation, mountain and stone placement engineering, garden water management engineering and garden revetment engineering, fountain engineering, garden water supply and drainage engineering, garden road engineering, planting engineering, etc. The characteristic of garden engineering is to use engineering technology as a means to shape the image of garden art.

[0003] When potted plants need to be placed in municipal parks for people to enjoy, some potted plants can only be planted in open squares in spring and summer, and need to be moved indoors or into greenhouses for planting and maintenance in winter.

[0004] When existing potted plants are planted outdoors for viewing, most of them are placed on the ground or on a shelf. Therefore, when the potted plants need to be watered or fertilized, maintenance personnel mostly directly use a spray pipe to spray water on the potted plants over a large area. However, if the fertilizer is sprayed directly, the sprayed fertilizer falls on the leaves of the potted plants and easily damages the leaves, thereby affecting the planting life of the potted plants. At the same time, large-scale watering easily causes a waste of water resources. If the potted plants are directly placed on the support frame, they are easily damaged in bad weather, thereby affecting the environmentally friendly and safe planting of the potted plants.

[0008] Furthermore, the width dimension of the clamping strip is greater than its height dimension, and rotating rods are connected to both ends of the clamping strip. A rotating hole is opened inside the connecting block, and a rotating rod is rotatably inserted in the rotating hole. The two adjacent vertical rotating rods are limitedly rotated by a limiting locking assembly, and the limiting locking assembly is arranged on the sides of two diagonally arranged connecting blocks.

[0009] Furthermore, the limit locking assembly includes a positioning block, a connecting column, a rotating column, a threaded column and a rotating disk. The two adjacent vertical rotating rod end faces are each provided with a square slot, and the two diagonal connecting blocks have threaded holes on their outer sides, and the threaded holes are connected to the rotating holes. The positioning block slides through the threaded holes and is slidably engaged with the direction slots, and the outer side surface of the positioning block is connected to the connecting column, the outer end surface of the connecting column is fixed with the rotating column, and the rotating column is rotatably connected to the threaded column through a bearing, the threaded column is threadedly connected to the threaded hole, and the outer end surface of the threaded column is connected to the rotating disk.

The compacting spray mechanism 4 rises to the upper surface of the planting pot 3 and is located at the root position of the plant, and then controls the compacting spray mechanism 4 to spray fertilizer to the root of the plant, so that the fertilizer will not fall directly on the leaves of the plant, and will not cause damage to the leaves of the plant. When it is necessary to spray and moisten the leaves of the plant, the maintenance personnel can control the compacting spray mechanism 4 to rise above the plant, so that the compacting spray mechanism 4 is higher than the total height of the plant, and then control the compacting spray mechanism 4 to work, so that the compacting spray mechanism 4 can spray water to moisten the leaves of the plant, and will not cause a large amount of water resource waste. When it is not necessary to spray water and fertilize the plants, the compacting spray mechanism 4 will descend to the upper surface of the potted support 2, so that the compacting spray mechanism 4 can compact and fix the potted support 2 and the planting pot 3, thereby preventing the existing potted plants from being easily caused to fall over and cause damage in windy weather due to the lack of a structure for fastening the potted plants when placed on the support frame.
