Abstract

Provided is a safe water spraying device for a garden lawn. The safe water spraying device for the garden lawn comprises a machine shell (1), an external driving motor (351) installed on the machine shell (1), a threaded driving sleeve (35), a driving sleeve (2), an internal driving motor (29), an internal threaded driving block (24) and a movable threaded rod (4); the threaded driving sleeve (35) is rotatable in the circumferential direction through a bearing and is axially and fixedly installed in a cavity (10) of the machine shell (1); the driving sleeve (2) is matched with an internal thread of the threaded driving sleeve (35); the internal driving motor (29) is axially and fixedly installed in a cavity (20) of the driving sleeve (2); the internal threaded driving block (24) which is subjected to circumferential driving of the internal driving motor (29) to be rotatable and is axially fixed, and the movable threaded rod (4) is matched with the internal threaded driving block (24) in a threaded mode; rolling wheel seats (51) are installed at the bottom of the machine shell (1), and a movable rolling wheel (52) is arranged on each rolling wheel seat (51) and used for driving the machine shell (1) to move.

Description

technical field [0001] The invention relates to the field of garden watering, in particular to a safety water spray device for garden lawns. Background technique [0002] Garden lawns can be used to beautify the environment and have a wide range of applications. The existing garden lawns generally cover a large area, which is difficult for later maintenance operations, and it is often necessary to spray water on the garden lawns, especially in summer. Some water spraying maintenance is generally divided into artificial watering and installing multiple sprinklers in the garden lawn for watering maintenance operations. The use of artificial watering is to use each worker to carry out sprinklers in the garden lawn for block spraying. Water, this will often invest a lot of manpower and material resources, and workers will damage the garden lawn if they walk for a long time in the garden lawn. In addition, installing multiple sprinklers for water spray maintenance will install mu...

[0002] Garden lawns can be used to beautify the environment and have a wide range of applications. The existing garden lawns generally cover a large area, which is difficult for later maintenance operations, and it is often necessary to spray water on the garden lawns, especially in summer. Some water spraying maintenance is generally divided into artificial watering and installing multiple sprinklers in the garden lawn for watering maintenance operations. The use of artificial watering is to use each worker to carry out sprinklers in the garden lawn for block spraying. Water, this will often invest a lot of manpower and material resources, and workers will damage the garden lawn if they walk for a long time in the garden lawn. In addition, installing multiple sprinklers for water spray maintenance will install multiple water delivery pipes under the garden lawn Supplying water to the sprinkler head will not only greatly increase the operating cost, but also is not convenient for motorized movement
