Description

Technical Field

[0001] The present application relates to the technical field of greening maintenance, and in particular to a greening maintenance device. Background Art

[0002] The later stage of greening construction, such as watering, pruning, weeding, spraying pesticides, and seedling replacement, is collectively referred to as greening maintenance. The work is simple, but essential and very important. Among them, watering or pouring nutrient solution on greening plants can ensure the survival rate of greening plants and is conducive to the normal growth of greening plants.

[0003] In traditional operations, workers usually carry containers filled with nutrient solution to water green plants, which requires manpower. Based on this, modern operations gradually use spray devices to water green plants. Specifically, the spray device is fixed to the ground, and the spray device is connected to a storage device through a delivery pipeline. The storage device is used to store nutrient solution. The delivery pump on the delivery pipeline can deliver the nutrient solution in the storage device to the spray device, and then spray it onto the surface of the green plants through the spray device to water the green plants.

[0004] With respect to the above-mentioned related technical solutions, when the area of ​​green plants to be irrigated is large, multiple spray devices need to be set up so that each spray device is responsible for spraying irrigation of green plants in a certain area. However, when the nutrient solution in the storage device is transported to the spray device via the delivery pipeline, part of the nutrient solution will accumulate and remain in the delivery pipeline. After the particulate matter in the nutrient solution precipitates and accumulates in the delivery pipeline, it may cause blockage of the delivery pipeline, thereby affecting the normal use of the spray device. At the same time, it will also cause waste of nutrient solution, which needs to be improved. Utility Model Content

[0055] Since the nutrient solution loaded into the storage bag 2 is quantitative, after the spike component 613 pierces the storage bag 2, the nutrient solution can completely flow into the placement chamber 31. Compared with the pipeline transportation method, it has the advantage of fully utilizing the nutrient solution, can reduce the waste of nutrient solution, and play a role in saving resources.
