Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse sprinkler irrigation, and particularly relates to a hand-held sprinkler irrigation device for a solar greenhouse. Technical Background

[0002] When cultivating crops in modern agricultural facilities such as solar greenhouses, sprinkler irrigation is generally selected to provide the water required for crop growth, and the ceiling-mounted sprinkler is the main sprinkler irrigation method. However, the existing sprinkler nozzles are relatively thin, have high requirements for water quality, and are extremely prone to nozzle blockage problems. Moreover, the sprinkler irrigation area is uncontrollable, and the required sprinkler irrigation time is also relatively long. At the same time, when cultivating on a large scale, since the crops are mainly cultivated in seedling trays on seedling beds in the solar greenhouse, the space without seedlings is relatively large, and using the ceiling-mounted sprinkler will cause a large waste of water resources.

Detailed implementation mode

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0025] Please refer to Figures 1 to 8 , the present invention provides a handheld sprinkler device 10 for solar greenhouse, including a handheld sprinkler gun 11. The handheld sprinkler gun 11 includes a handheld rod 111, a movable rod 112, a sprinkler assembly 113, a water supply hose 114 and a rotating and extending assembly 115; both the handheld rod 111 and the movable rod 112 are hollow long rods, the movable rod 112 is sleeved in the handheld rod 111, the water supply hose 114 passes through the movable rod 112 and is connected to the sprinkler assembly 113 to supply water to the sprinkler assembly 113. The sprinkler assembly 113 is fixedly installed at one end of the movable rod 112, and the rotating and extending assembly 115 is fixedly installed on the handheld rod 111 and fixedly connected to the other end of the movable rod 112 to extend the movable rod 112 out of the handheld rod 111, extending the sprinkler distance and thus expanding the sprinkler range.

[0026] The handheld sprinkler device 10 for solar greenhouse is particularly suitable for the sprinkler operation of crop cultivation in seedling bed plug trays in solar greenhouses, and can extend the movable rod 112 out of the handheld rod 111 through the rotating and extending assembly 115, extending the sprinkler distance and thus expanding the sprinkler range.

[0027] In one embodiment, both the handheld rod 111 and the movable rod 112 are long stainless steel tubes. The movable rod 112 is sleeved in the handheld rod 111, which can ensure the strength of the handheld rod 111 and the movable rod 112 while avoiding damage to the device and reduction of service life caused by rusting during sprinkler irrigation operations.

[0028] Furthermore, one end of the movable rod 112 is provided with a connecting external thread 1121, and the other end is provided with a connecting fixing member 1122, which is used to fixedly connect the movable rod 112 with the rotating and extending assembly 115 through the connecting fixing member, and fixedly connect the sprinkler irrigation assembly 113 with the movable rod 112 through thread fitting, facilitating disassembly and replacement.

[0029] Furthermore, one end of the handheld rod 111 is provided with a hand gripping member 1111. The movable rod 112 is sleeved in the handheld rod 111 and extends out from the other end of the handheld rod 111. A connecting fixing member sliding groove 1112 is also formed on the handheld rod 111, and the connecting fixing member 1122 on the movable rod 112 can slide therein. The hand gripping member 1111 is made of hydrophobic fabric, which is used to wind and fix on the handheld rod 111 to increase the friction and comfort of hand gripping, while avoiding the reduction of friction and the decline of gripping stability caused by the water absorption of the hand gripping member 1111.

[0030] Furthermore, the sprinkler irrigation assembly 113 includes a nozzle mounting assembly 1131, a nozzle 1132 and a knob switch 1133. At least one nozzle 1132 is mounted on the nozzle mounting assembly 1131, and each nozzle 1132 is communicated with a knob switch 1133 to adjust the water spraying amount of the corresponding nozzle 1132 through the knob switch 1133. A connecting joint 1136 and a water supply hose joint 1135 are also provided on the nozzle mounting assembly 1131. A connecting internal thread 1134 is arranged inside the connecting joint 1136 for mating connection with the connecting external thread 1121 on the movable rod 112. The water supply hose joint 1135 is used to fixedly connect with the water supply hose 114 to supply water to the nozzle 1132. The water column sprayed by the nozzle 1132 is conical, which is beneficial to sprinkler irrigation of crops, avoiding less spraying and leakage spraying. Each nozzle 1132 is communicated with a knob switch 1133 to realize the adjustment of the water output of a single nozzle 1132, avoiding the problems of overspraying or underspraying, and at the same time, it can also realize the sprinkler irrigation of multiple crops with different required water amounts in a single time.

[0031] Further, the rotating and extending assembly 115 includes a first fixed pulley 1151, a second fixed pulley 1152, a rotating handle 1153, and a steel wire 1154; the first fixed pulley 1151 is fixedly installed at one end of the handheld rod 111 close to the connecting external thread 1121, the second fixed pulley 1152 is installed at one end of the handheld rod 111 close to the hand grip 1111, the rotating handle 1153 is installed on the second fixed pulley 1152, the steel wire 1154 is sleeved on the first fixed pulley 1151 and the second fixed pulley 1152, and the connecting and fixing member 1122 is installed in the chute 1112 of the connecting and fixing member 1122 of the handheld rod 111 and is fixedly connected to the steel wire 1154; by rotating the rotating handle 1153, the steel wire 1154 sleeved on the first fixed pulley 1151 and the second fixed pulley 1152 moves, and drives the connecting and fixing member 1122 installed in the chute 1112 of the connecting and fixing member of the handheld rod 111 to move, thereby driving the movable rod 112 to extend from the handheld rod 111, extending the spray irrigation distance and expanding the spray irrigation range.

[0032] Further, a water supply hose coiling assembly 116 is further provided at one end of the handheld rod 111 close to the hand grip 1111, including a reel fixing frame 1161 and a hose reel 1162; the reel fixing frame 1161 is fixedly installed at one end of the handheld rod 111 close to the hand grip 1111, and the hose reel 1162 is rotatably installed on the reel fixing frame 1161 for coiling the water supply hose 114. The reel for coiling the water supply hose 114 can balance the weight of one end of the spray irrigation assembly 113 when holding the spray irrigation, avoiding the situation that one end of the spray irrigation assembly 113 is too heavy due to the long extension of the movable rod 112, which makes it difficult for the staff to hold.

[0033] In the above embodiment, the handheld spray irrigation device 10 for solar greenhouse further includes a suspension beam 12, a suspension walking assembly 13, an adjustment master switch 14, and a water pump 15. The suspension beam 12 is fixedly installed above the solar greenhouse for suspending and carrying the suspension walking assembly 13; the suspension walking assembly 13 is movably installed on the suspension beam 12 for suspending the water supply hose 114. By using the suspension walking assembly 13 to suspend the water supply hose 114, it is convenient for the staff to move forward during spray irrigation, and at the same time, it effectively reduces the area available for planting in the greenhouse occupied by the spray irrigation device; the water pump 15 is connected to the water supply hose 114 to supply water to the handheld spray gun 11. The adjustment master switch 14 is arranged on the water supply hose 114, which is convenient for controlling the total water output of all the nozzles 1132 on the spray irrigation assembly 113 by adjusting the master switch 14. At the same time, in cooperation with the knob switch 1133 on the spray irrigation assembly 113, the water output of each nozzle 1132 can be controlled more accurately. The handheld spray gun 11 can also be suspended by connecting it to the suspension walking assembly 13 with a steel wire, reducing the arm burden and labor intensity of the staff.

[0034] Furthermore, the hanging walking assembly 13 includes a walking frame 131, upper walking wheels 132, side limiting wheels 133, limiting wheel mounting brackets 134, hook connectors 135 and hooks 136; the walking frame 131 is a "mouth"-shaped frame, and the limiting wheel mounting brackets 134 are mounted in pairs on both sides of the opening of the walking frame 131. The side limiting wheels 133 are rotatably mounted on the limiting wheel mounting brackets 134, and the upper walking wheels 132 are rotatably mounted above the inside of the walking frame 131. There is a gap between the upper walking wheels 132 and the side limiting wheels 133 for clamping the hanging beam 12 between the upper walking wheels 132 and the side limiting wheels 133. The hook connectors 135 are rotatably mounted below the walking frame 131, and the hooks 136 are rotatably mounted on the hook connectors 135.

[0035] When the utility model is implemented, the water pump 15 needs to be turned on first. The total regulating switch 14 on the water supply hose 114 is used to regulate the water volume and intensity of the water sprayed by the nozzles 1132 on the sprinkler irrigation assembly 113 to avoid excessive or insufficient water volume. At the same time, the knob switch 1133 is adjusted so that the water volume of the nozzles 1132 on the sprinkler irrigation assembly 113 is kept consistent. If multiple crops need to be irrigated at one time, the knob switch 1133 on the corresponding nozzle 1132 can be adjusted. After the water volume adjustment is completed, the water supply hose 114 is coiled around the hanging walking assembly 13, and the hand-held sprinkler gun 11 is used for sprinkler irrigation. When the length of the sprinkler gun needs to be adjusted, the rotating handle 1153 mounted on the second fixed pulley 1152 is rotated, and the steel wire 1154 sleeved on the first fixed pulley 1151 and the second fixed pulley 1152 moves, driving the connecting fixture 1122 installed in the connecting fixture chute 1112 of the hand-held rod 111 to move, thereby driving the movable rod 112 to extend from the hand-held rod 111, extending the sprinkler irrigation distance and expanding the sprinkler irrigation range. When sprinkler irrigation is carried out by hand, if the movable rod 112 extends too long, resulting in one end of the sprinkler irrigation assembly 113 being too heavy and difficult to hold for sprinkler irrigation, the hand-held sprinkler gun 11 and the hanging walking assembly 13 can be connected by a steel wire to hang and lift the hand-held sprinkler gun 11, and the weight of one end of the sprinkler irrigation assembly 113 can be balanced by the reel for coiling the water supply hose 114, reducing the arm burden and labor intensity of the staff.

[0036] The modules or units in the device of the embodiment of the utility model can be combined, divided and deleted according to actual needs. The above-disclosed is only the preferred embodiment of the utility model, and of course, it cannot be used to limit the scope of the rights of the utility model. Those of ordinary skill in the art can understand the whole or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the utility model still fall within the scope covered by the utility model.
