Technical Field
[0001] This utility model relates to the field of vegetable planting technology, specifically a greenhouse vegetable spraying device. Background Technology
[0002] Irrigation, fertilization, and pest and disease control are key aspects of greenhouse vegetable cultivation. As consumers' demands for the quality and safety of agricultural products increase, higher requirements are also being placed on the precision and intelligence of irrigation.
[0003] A search revealed a utility model patent with Chinese patent publication number CN221979656U, which discloses a greenhouse vegetable spraying device. By setting up a stirring mechanism and a cleaning mechanism, the device can be cleaned during the spraying process, preventing water rust from clogging the equipment and increasing its service life. The device includes a spraying mechanism, a stirring mechanism, a filtering mechanism, and multiple sets of cleaning mechanisms.
[0004] As with the above-mentioned sprinkler system, all the nozzles are installed on the same pipe, so the area covered by the spray is also fixed. If the planting area inside the greenhouse is smaller than the area covered by the spray, the excess water cannot be used and will be wasted. Utility Model Content
[0005] The purpose of this utility model is to provide a greenhouse vegetable spraying device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse vegetable spraying device, comprising a support frame, a flow-stopping component installed at the top of the support frame, the flow-stopping component comprising a support plate fixedly connected to the outer wall of the top of the support frame, a hydraulic cylinder fixedly installed on the outer wall of the top of the support plate, a horizontally arranged movable frame fixedly connected to the output end of the hydraulic cylinder, an installation rod fixedly inserted inside the movable frame, a plurality of equally spaced sealing components installed outside the installation rod, a horizontally arranged spray pipe fixedly installed at the top of the support frame, a plurality of equally spaced nozzles arranged at the bottom of the outer circumference of the spray pipe, and a plurality of flow-stopping components corresponding to the positions of the plurality of nozzles.
[0007] As a further preferred embodiment of this technical solution, the sealing assembly includes a blocking frame rotatably sleeved on the outer circumference of the mounting rod, a positioning rod slidably inserted inside the blocking frame, two limiting holes adapted to the positioning rod being opened on the outer circumference of the mounting rod, the same spring being fixedly connected between the end of the positioning rod and the blocking frame, the spring being sleeved on the outside of the positioning rod, and a horizontally arranged sealing gasket being provided on the bottom outer wall of the blocking frame.
[0008] By controlling the spray pattern of the sprinkler heads according to the plant distribution, water resources are effectively saved, and muddy conditions in non-planted areas are successfully avoided. If one or more sprinklers are not needed, the movable end of the blocking bracket can be pushed down as needed. The blocking bracket will flip along the mounting rod, and the positioning rod in the top limit hole will also be dislodged by the pressure due to the spring. Then the positioning rod moves to the opposite side of the bottom limit hole, the spring is no longer under force, and the positioning rod can be driven to be inserted into the bottom limit hole. Then the hydraulic cylinder at the top of the support plate is activated, and the output end of the hydraulic cylinder drives the moving bracket to move upward. The blocking bracket opposite the sprinkler head on the mounting rod will be squeezed at its port, and the water flow into the sprinkler pipe will not flow out from the blocked sprinkler head.
[0009] As a further preferred embodiment of this technical solution, a water tank is fixedly installed on one side of the outer wall of the support frame, and a water pump is fixedly installed on the top outer wall of the water tank. The outlet of the water pump is connected to the same pipe as the spray pipe, and the inlet of the water pump extends into the bottom of the water tank.
[0010] As a further preferred embodiment of this technical solution, a filter assembly is installed inside the water tank. The filter assembly includes a lead screw rotatably connected inside the water tank, a horizontally set limiting rod fixedly connected inside the water tank, a filter frame slidably sleeved on the outside of the limiting rod, and a filter plate made of the lower half of the filter frame. The filter frame is threaded onto the outside of the lead screw. A motor is fixedly installed on the outer wall of one end of the water tank, and the output end of the motor is coaxially fixed with one end of the lead screw.
[0011] Impurities in the water will accumulate in the filter frame. When the impurities accumulate to a certain level, the motor outside the water tank is started, and the lead screw rotates accordingly. Driven by the lead screw and in cooperation with the limit rod, the filter frame swings back and forth inside the water tank. In this way, the impurities stuck in the filter holes of the filter frame will be flushed away by the water flow, which helps to maintain the filtration efficiency.
[0012] As a further preferred embodiment of this technical solution, the edges of several of the limiting holes are provided with rounded corners, and the insertion end of the positioning rod is provided with a rounded head.
[0013] As a further preferred embodiment of this technical solution, the water pump's inlet pipe is wrapped with a filter sleeve.
[0014] As a further preferred embodiment of this technical solution, the filter frame is arranged in a parallelogram shape.
[0015] This utility model provides a greenhouse vegetable spraying device, which has the following beneficial effects:
[0016] (1) By setting a flow-stopping component, this utility model controls the water spraying state of the sprinkler head according to the plant distribution, which not only effectively saves water resources, but also successfully avoids muddy phenomena in non-planting areas. If one or more sprinklers do not need to spray water, the movable end of the blocking frame can be pushed down as needed. The blocking frame will flip along the mounting rod, and the positioning rod in the top limit hole will also be dislodged due to pressure. Then the positioning rod moves to the opposite side of the bottom limit hole, the spring is no longer under force, and the positioning rod can be driven to be inserted into the bottom limit hole. Then the hydraulic cylinder at the top of the support plate is activated, and the output end of the hydraulic cylinder drives the moving frame to move up. The blocking frame facing the nozzle of the mounting rod will be squeezed at its port, and the subsequent water flow into the sprinkler pipe will not flow out from the sealed nozzle.
[0017] (2) By setting up a filter assembly, impurities in the water will be concentrated in the filter frame. When the impurities accumulate to a certain extent, the motor outside the water tank is started, and the lead screw rotates accordingly. Driven by the lead screw and in cooperation with the limit rod, the filter frame swings back and forth inside the water tank. In this way, the impurities stuck in the filter holes of the filter frame will be flushed away by the water flow, which helps to maintain the filtration efficiency. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3As shown in this embodiment, a greenhouse vegetable spraying device includes a support frame 1. A flow-stopping component 5 is installed at the top of the support frame 1. The flow-stopping component 5 includes a support plate 501 fixedly connected to the top outer wall of the support frame 1. A hydraulic cylinder 502 is fixedly installed on the top outer wall of the support plate 501. A horizontally arranged movable frame 503 is fixedly connected to the output end of the hydraulic cylinder 502. An installation rod 504 is fixedly inserted inside the movable frame 503. Several equally spaced sealing components are installed on the outside of the installation rod 504. A horizontally arranged spray pipe 4 is fixedly installed at the top of the support frame 1. Several equally spaced nozzles are arranged at the bottom of the outer circumference of the spray pipe 4. Several flow-stopping components 5 correspond to the positions of several nozzles.
[0025] The sealing assembly includes a blocking frame 505 that is rotatably sleeved on the outer circumference of the mounting rod 504. A positioning rod 506 is slidably inserted inside the blocking frame 505. Two limiting holes 508 adapted to the positioning rod 506 are opened on the outer circumference of the mounting rod 504. The same spring 507 is fixedly connected between the end of the positioning rod 506 and the blocking frame 505. The spring 507 is sleeved on the outside of the positioning rod 506. A horizontally arranged sealing gasket 509 is provided on the bottom outer wall of the blocking frame 505.
[0026] If one or more nozzles are not needed, the movable end of the blocking bracket 505 can be pushed down as needed. The blocking bracket 505 will flip along the mounting rod 504, and the positioning rod 506, which is in the top limiting hole 508 driven by the spring 507, will also be released due to pressure. Then the positioning rod 506 moves to the opposite side of the bottom limiting hole 508, the spring 507 is no longer under force, and the positioning rod 506 can be driven to be inserted into the bottom limiting hole 508. Then the hydraulic cylinder 502 at the top of the support plate 501 is activated. The output end of the hydraulic cylinder 502 drives the moving bracket 503 to move upward. The blocking bracket 505 facing the nozzle of the mounting rod 504 will be squeezed at its port. After the water flows into the spray pipe 4, it will not flow out from the closed nozzle.
[0027] like Figure 1 and Figure 2 As shown, a water tank 2 is fixedly installed on one side of the outer wall of the support frame 1, and a water pump 3 is fixedly installed on the top outer wall of the water tank 2. The outlet of the water pump 3 is connected to the same pipe as the spray pipe 4, and the inlet of the water pump 3 extends into the bottom of the water tank 2.
[0028] Start the water pump 3 at the top of the water tank 2. The filtered water is pumped into the spray pipe 4 by the water pump 3, and then sprayed downwards through multiple nozzles at the bottom of the spray pipe 4.
[0029] like Figure 2 and Figure 4As shown, a filter assembly 6 is installed inside the water tank 2. The filter assembly 6 includes a lead screw 601 rotatably connected inside the water tank 2, a horizontally set limiting rod 602 fixedly connected inside the water tank 2, a filter frame 603 slidably sleeved on the outside of the limiting rod 602, and a filter plate made of the lower half of the filter frame 603. The filter frame 603 is threaded on the outside of the lead screw 601. A motor 604 is fixedly installed on the outer wall of one end of the water tank 2. The output end of the motor 604 is coaxially fixed with one end of the lead screw 601.
[0030] Impurities in the water will concentrate in the filter frame 603. When the impurities accumulate to a certain extent, the motor 604 outside the water tank 2 is started, and the lead screw 601 rotates accordingly. Driven by the lead screw 601 and in cooperation with the limit rod 602, the filter frame 603 swings back and forth inside the water tank 2. In this way, the impurities stuck in the filter holes of the filter frame 603 will be flushed away by the water flow, which helps to maintain the filtration efficiency.
[0031] like Figure 3 As shown, the edges of several limiting holes 508 are rounded, and the insertion end of the positioning rod 506 is rounded, making it easier for the positioning rod 506 to move out of the limiting hole 508.
[0032] like Figure 4 As shown, the water pump 3 has a filter sleeve wrapped around its inlet pipe, which forms another layer of protection outside the inlet and effectively prevents impurities from entering the spray nozzle of the spray pipe 4.
[0033] like Figure 1 and Figure 2 As shown, the filter frame 603 is arranged in a parallelogram shape. When the filter frame 603 is translated, the water flow can also impact the inclined surface, which helps to improve the backwashing effect.
[0034] This utility model provides a greenhouse vegetable spraying device, the specific working principle of which is as follows:
[0035] When the device is working, water is poured into the filter frame 603. This water is filtered by the filter frame 603 before entering the water tank 2. Additionally, the water pump 3 at the top of the water tank 2 is activated, pumping the filtered water into the spray pipe 4. The water is then sprayed downwards through multiple nozzles at the bottom of the spray pipe 4. If one or more nozzles are not needed, the movable end of the blocking bracket 505 can be moved downwards. The blocking bracket 505 will flip along the mounting rod 504, causing the positioning rod 506, which is located in the top limiting hole 508, to disengage due to pressure, driven by the spring 507. The positioning rod 506 then moves to the opposite side of the bottom limiting hole 508, and the spring 507 is no longer under force. The positioning rod 506 can then be inserted into the bottom limiting hole 508. Next, the hydraulic cylinder 502 on top of the support plate 501 is activated. The output end of the hydraulic cylinder 502 drives the moving frame 503 to move upward. The blocking frame 505 facing the nozzle of the mounting rod 504 will be squeezed at its port. After the water flows into the spray pipe 4, it will not flow out from the sealed nozzle. Furthermore, because the flow-stopping component 5 is located outside the spray pipe 4, the repair process is more convenient. In addition, impurities in the water will be concentrated in the filter frame 603. When the impurities accumulate to a certain extent, the motor 604 outside the water tank 2 is activated, and the lead screw 601 rotates accordingly. Driven by the lead screw 601 and in cooperation with the limit rod 602, the filter frame 603 swings back and forth inside the water tank 2. In this way, the impurities stuck in the filter holes of the filter frame 603 will be flushed away by the water flow, which helps to maintain the filtration efficiency.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
