Description

Technical Field

[0001] The utility model relates to the technical field of plant maintenance, in particular to a plant protection spray device. Background Art

[0002] Plants are one of the primary forms of life, encompassing familiar organisms such as trees, shrubs, vines, grasses, ferns, algae, and lichens. Plant protection is also known as phytomedicine. Plant protection spraying refers to the application of pesticides, insecticides, fungicides, and other plant protection agents to or around plant leaves. Spraying effectively and evenly distributes the protective agent to the plant surface, preventing or controlling pests and diseases.

[0003] Since plant protection spray devices are mostly used in parks, wetlands and other places, when the spray device is idle, dust, pollen, broken leaves, etc. can easily float into the water holes of the nozzle. As time accumulates, it can easily cause the nozzle to be clogged, affecting the use of the nozzle.

[0004] Therefore, we propose a plant protection spray device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-3 As shown, the utility model provides a plant protection spray device, including a support frame 1, a spray mechanism 4 and a protective mechanism 5. The support frame 1 is fixed to the ground, a pipe clamp 2 is provided on the support frame 1, a liquid holding pipe 3 is clamped on the pipe clamp 2, a spray mechanism 4 is provided on the top of the liquid pipe 3, and a protective mechanism 5 is provided on the spray mechanism 4;

[0025] The spray mechanism 4 includes a liquid separator 41 mounted on the top of the liquid pipe 3 and a branch pipe 42 provided on the side wall of the liquid separator 41. A plurality of branch pipes 42 are arranged circumferentially along the side wall of the liquid separator 41. An atomizing nozzle 43 is provided on the branch pipe 42.

[0026] The protective mechanism 5 includes a sliding plate 51 slidably installed in the liquid separator cylinder 41 and a connecting rod 52 fixed to the top of the sliding plate 51. The sliding plate 51 can be made of a rubber plate, and its diameter is equal to the inner diameter of the liquid separator cylinder 41 to improve the sealing of the liquid separator cylinder 41 and prevent water from spraying out from the top of the liquid separator cylinder 41. The top of the connecting rod 52 passes through the top wall of the liquid separator cylinder 41 and is fixed with a connecting plate 53. A protective plate 54 is provided on the connecting plate 53, which abuts against the atomizing nozzle 43. The connecting plate 53 and the protective plate 54 both correspond to the liquid separator cylinder 41 one by one.

[0027] The protective mechanism 5 is in a closed state under normal circumstances. The contact between the protective plate 54 and the atomizing nozzle 43 protects the nozzle and prevents external debris from clogging the water spray hole. When in use, the water pushes the sliding plate 51 upward, driving the protective plate 54 to move upward, so that it is separated from the atomizing nozzle 43 and will not affect the spraying range of the nozzle.

[0028] As an optimal technical solution of the present invention: a guide plate 8 is vertically fixed to the side wall of the first connecting rod 521, and a guide groove is provided on the top of the liquid separator 41 to be slidably connected to the guide plate 8. The guide plate 8 is a strip structure. The setting of the guide plate 8 and the guide groove prevents the connecting plate 53 and the protective plate 54 from rotating circumferentially, so as to prevent the protective plate 54 from being unable to fit with the atomizing nozzle 43 when resetting.

[0029] As a preferred technical solution of the present invention: the connecting rod 52 includes a first connecting rod 521 fixed on the top of the sliding plate 51 and a second connecting rod 522 fixed on the bottom of the connecting plate 53, a threaded rod 523 is fixed at the bottom of the second connecting rod 522, and a threaded groove threadedly connected to the threaded rod 523 is opened at the top of the first connecting rod 521.

[0030] The connection rod 52 is arranged so that when the connection plate 53 and the protection plate 54 are damaged, they can be replaced separately without replacing the entire device, thereby reducing the use cost.

[0031] As an optimal technical solution of the present invention: a column 6 is provided on the top of the connecting rod 52, and a plurality of counterweight rings 7 are sleeved on the column 6. The number of the counterweight rings 7 can be appropriately increased or decreased according to the spraying water pressure at that time; if the water pressure is too low, the number of the counterweight rings 7 is reduced to prevent the protective plate 54 from being unable to completely separate from the atomizing nozzle 43 when the water pressure is too low, thereby affecting the spraying of the atomizing nozzle 43; if the water pressure is too high, the number of the counterweight rings 7 is increased to prevent the sliding plate 51 from having excessive friction with the inner wall of the liquid separator 41, resulting in the sliding plate 51 being unable to return to its position.

[0032] In the description of the present invention, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. In this article, the meaning of "plurality" is two or more, unless otherwise clearly defined.

[0033] For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances; for technicians in this field, they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
