Description

Technical Field

[0001] The invention relates to the technical field of atomization processing equipment, and in particular to an atomization device and a method thereof which are convenient for comprehensive self-cleaning. Background Art

[0002] Greenhouses are buildings that use lighting covering materials as all or part of the enclosure structure materials and can be used to cultivate plants in winter or other seasons that are not suitable for outdoor plant growth. In greenhouses, crops such as vegetables and flowers need to be sprayed, fertilized, and applied. In order to improve the effects of spraying, fertilizing, and applying medicine, it is generally necessary to use an atomizer to atomize the liquid containing medicine or fertilizer. Therefore, atomization equipment is an important equipment in greenhouses. The atomization devices of existing greenhouses include two types. One type is a fixed device, in which multiple nozzles are arranged in the greenhouse, and the nozzles are connected to the atomization mechanism. This type of structure requires many pipes and nozzles, and the overall equipment investment is high. One type is a mobile device, in which the atomization device is fixed on a track, and the atomization device is driven to move by the movement of the track to achieve the overall atomization spraying of the greenhouse. In this type of structure, the atomization nozzle is generally fixed, and the spray height cannot be conveniently adjusted, resulting in its poor applicability.

[0003] Atomization equipment is generally a common device for watering, fertilizing and spraying, so the spray equipment needs to be thoroughly cleaned before and after use. However, existing atomization equipment generally does not contain self-cleaning equipment, or only contains a cleaning mechanism for the atomization container, and there is no cleaning equipment for the spray pipe and nozzle. Because there will be a certain amount of pesticide and fertilizer residues in the spray pipe and nozzle, if they are not cleaned thoroughly, the pesticide and fertilizer will enter the crop with the spray, increasing the risk of excessive pesticide and fertilizer residues in the crop and equipment clogging.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

One end is connected to the outlet end of the water pump 21 through a quick connector, and the other two ends are respectively provided with a left cleaning valve 6 and a right cleaning valve 8. The inlet end of the water pump 21 is provided with a water inlet tee 4; the two inlet ends of the water inlet tee 4 are provided with a water inlet valve 3 and a circulation valve 2;

[0038] A liquid outlet four-way joint 19 is provided at the bottom of the liquid storage tank 15, one end of the liquid outlet four-way joint 19 is connected to the liquid storage tank 15, and the other three ends are respectively provided with a drain valve 18, a left liquid outlet valve 17 and a right liquid outlet valve 20, and quick connectors are provided at the ends of the water inlet valve 3, the water outlet valve 44, the circulation valve 2, the left cleaning valve 6, the right cleaning valve 8, the drain valve 18, the left liquid outlet valve 17 and the right liquid outlet valve 20;

[0039] A liquid dispensing pipe 10 is provided in the liquid storage tank 15, the middle part of the liquid dispensing pipe 10 is connected to the liquid inlet four-way joint 7, the liquid dispensing pipe 10 is horizontally arranged along the upper part of the liquid storage tank 15, the two ends of the liquid dispensing pipe 10 are bent toward the middle part of the liquid storage tank 15, and one end of the liquid dispensing pipe 10 is at a height of 2 / 3-3 / 4 of the liquid storage tank 15, and the other end is at 1 / 4-1 / 3 of the liquid storage tank 15, and the four curved parts and the horizontal part of the liquid dispensing pipe 10 are provided with a plurality of cleaning nozzles 11 with the spray direction facing the wall of the liquid storage tank 15; in this embodiment, one end of the liquid dispensing pipe 10 is at a height of 2 / 3 of the liquid storage tank 15, and the other end is at 1 / 3 of the liquid storage tank 15. The arrangement of the above-mentioned liquid dispensing pipe 10 can be used to perform stirring and flushing of the interior of the liquid storage tank 15 without dead angles.

[0040] The spray mechanism consists of two, the spray mechanism includes a hanger 12, a drive motor 34 is arranged inside the hanger 12, the output end of the drive motor 34 is fixedly connected to a drive gear 33, a transmission rod 35 is arranged on the side of the drive motor 34, a tooth groove 32 is opened in the middle of the transmission rod 35, the drive gear 33 and the tooth groove 32 are meshed with each other, and the two ends of the transmission rod 35 are connected to a transmission wheel 37 through a transmission belt 36, and the transmission wheel 37 is coaxially connected to the capstan 22.

[0041] The bottom of the hanger 12 is rotatably connected to a winch 22, a pulley 38 is provided on the side of the winch 22, a suspension rope 23 is hinged on the surface of the winch 22, the bottom of the suspension rope 23 is fixedly connected to a connecting plate 24, and a spray end is fixed below the connecting plate 24 by bolts.

[0042] Specifically, two capstans 22 are provided, the pulley 38 is provided in the middle of the capstan 22, the suspension ropes 23 on the two capstans 22 are respectively fixed at both ends of the connecting plate 24, the middle part of the connecting plate 24 is hollowed out, and the hose 16 passes through the hollow position and is fixed at the top of the spray end.

[0043] In this embodiment, when the winch 22 rotates, it reels the suspension rope 23, and the suspension rope 23 pulls the connecting plate 24 to rise and fall, thereby adjusting the height of the spray end installed under the connecting plate 24. The hose 16 bypasses the pulley 38 and passes through the connecting plate 24, and is then connected to the spray end. During the process of the spray end rising and falling, the hose 16 slides on the pulley 38, and the setting of the pulley 38 reduces the sliding resistance of the hose 16.

[0044] Specifically, the output end of the driving motor 34 is fixedly connected to the driving gear 33, and a transmission rod 35 is provided on the side of the driving motor 34. A tooth groove 32 is opened in the middle of the transmission rod 35, and the driving gear 33 and the tooth groove 32 are meshed with each other. The two ends of the transmission rod 35 are connected to the transmission wheel 37 through the transmission belt 36, and the transmission wheel 37 is coaxially connected to the capstan 22.

[0045] In this embodiment, when the driving motor 34 is working, it drives the driving gear 33 to rotate, and then drives the transmission rod 35 to rotate, and drives the transmission wheel 37 to rotate through the transmission belt 36, and then the capstan 22 rotates.

[0046] The above structure can be used to adjust according to the height of the plants planted in the greenhouse to improve the adaptability of the atomizer to the planted plants. The spray end can also be raised during other planting operations such as fertilizing and harvesting to prevent equipment interference and improve the flexibility of the atomizer. By setting a liquid storage tank 15 and combining it with two hangers 12, the atomization water is temporarily stored. During operation, only the liquid storage tank 15 needs to be regularly supplied with water, which reduces the number of water pipes that need to be connected in the greenhouse. At the same time, the water pipes and wires connected between the liquid storage tank 15 and the hanger 12 are hung on the top of the greenhouse, thereby improving the neatness of the atomization treatment device, reducing the pipelines required for the atomization device, and providing space for the installation of other equipment in the greenhouse.

[0047] An atomizing pump 25 is arranged inside the spray end, and the input end of the atomizing pump 25 is connected to the left liquid outlet valve 17 or the right liquid outlet valve 20 through a hose 16. The output end of the atomizing pump 25 is provided with a spray nozzle 30, and a sealing plate 26 is arranged on the upper part of the spray nozzle 30.

The connecting rod 13 is movably fixed on the hanger 12. The connecting rod 13 can be fixed on the hanger 12 by a shaft sleeve structure, or by a gear meshing method, or by a hydraulic rod. In this embodiment, the shaft sleeve structure is fixed on the hanger 12, and it is rotated manually. Of course, a power mechanism can also be added to make it rotate automatically.

[0049] A sealing layer 27 is disposed on the upper portion of the semicircular cleaning head 14. The sealing layer 27 is made of an elastic material and mainly acts together with the sealing plate 26 to seal the spray nozzle 30. Other sealing structures may be used.

[0050] A cleaning three-way joint 29 is provided at the bottom of the semicircular cleaning head 14. A drain valve 28 and a backflush valve 31 are provided at both ends of the cleaning three-way joint 29. The outlet ends of the drain valve 28 and the backflush valve 31 are both provided with quick connectors.

[0051] The moving mechanism is used to drive the spray mechanism and the liquid storage mechanism to move horizontally, and includes a track 5 set on the shed. The liquid storage mechanism and the spray mechanism are installed together with the track 5 through the fixed plate 1. The track 5 drives the liquid storage mechanism and the spray mechanism to move horizontally. The track 5 in this embodiment refers to the track structure with a power device.

[0052] In this embodiment, one track 5 is used to drive the whole device to move. If the greenhouse is relatively wide, a combination of two driven tracks and one active track can be used, the two driven tracks are fixed together with the spray mechanism, the active track is fixed together with the liquid storage mechanism, and the active track drives the driven track to move, thereby realizing the synchronous horizontal movement of the liquid storage mechanism and the spray mechanism.

[0053] The control system 45 includes a PLC controller, a temperature sensor, a liquid level sensor and a concentration sensor. The function of the concentration sensor is to measure the concentration of the drug or fertilizer in the solution in the liquid storage tank 15. A sensor that can measure the above data can be used.

The liquid storage mechanism, spray mechanism, cleaning mechanism, moving mechanism, the temperature sensor, liquid level sensor and concentration sensor are electrically connected to the PLC controller respectively.

[0054] Of course, a wireless transmission mechanism can also be set up to achieve remote control of the device, which will not be described further.

[0055] Example 2

[0056] like Figure 5 As shown, the spray mechanism in Example 1 has only one nozzle, and the spray area is not large. If a larger spray area is required, another structure can be used, as follows:

[0057] An atomizing pump 25 is arranged inside the spray end, and the input end of the atomizing pump 25 is connected to the left liquid outlet valve 17 or the right liquid outlet valve 20 through a hose 16. A spray nozzle 30 is arranged at the output end of the atomizing pump 25. Bridges are fixedly connected to both sides of the spray end, and a spray nozzle 30 is also arranged at the bottom of the bridge.

[0058] Specifically, the bridge frame includes a main frame 39 and a sub-frame 41. A slot 40 is provided at the end of the main frame 39. A plug plate 42 is provided at one end of the sub-frame 41. The plug plate 42 is plugged and connected to the slot 40 and fixed by bolts. The other end of the sub-frame 41 is also provided with a slot 40.

The bottom of the main frame 39 and the sub-frame 41 are both provided with a spray nozzle 30. The connecting pipe 43 is connected to the spray nozzle 30. A sealing plate 26 is provided on the upper part of the spray nozzle 30.

[0059] In this embodiment, the main frame 39 cooperates with the sub-frame 41, and the sub-frame 41 is connected in series on the side of the main frame 39 to form a bridge structure, so as to adjust the width of the spray end, change the number of spray nozzles 30 below the spray end, and increase the coverage width of the water mist sprayed by the spray device.

[0060] With respect to the above structure, the structure of the cleaning mechanism needs to be changed, and a structure in which several semicircular cleaning heads 14 are connected can be used, which will not be described in detail.

[0061] Example 3

[0062] A greenhouse atomization and cleaning method, using the atomization device of embodiment 1, comprises the following steps:

[0063] (1) The solution is mixed evenly: 1 / 3 of clean water is added to the water storage tank through the water inlet valve 3 of the water pump 21, and then the pesticide or fertilizer is added through the feeding port 9, and then water is added. The water is sprayed out at high speed through the nozzle and the two ends of the liquid distribution pipe 10, pushing the pesticide or fertilizer in the liquid storage tank 15 to mix with the clean water. When the water is added, the water inlet valve 3 of the water pump 21 is connected to the drain valve 18 of the water storage tank through the hose 16, the circulation valve 2 and the drain valve 18 are opened, and the water pump 21 is started to circulate the solution in the water storage tank inside and outside, so as to achieve uniform mixing of the pesticide or fertilizer and the clean water;

[0064] (2) Atomization spray: connect the left and right liquid outlet valves 20 to the atomization nozzle through the hose 16, then open the left and right liquid outlet valves 20, start the drive motor 34, lower the spray nozzle 30 to the spray position, then start the atomization pump 25 to spray the liquid in atomized form, and at the same time start the track to drive the synchronous horizontal movement of the liquid storage mechanism and the spray mechanism to perform the atomization spray operation;

[0065] (3) Cleaning: After the atomization spray is completed, the spray nozzle 30 is manually fixed to the semicircular cleaning head 14, and the spray nozzle 30 is sealed by working together with the sealing plate 26. The drain valve 28 is connected to the hose 16 through a quick connector, and the other end of the hose 16 is connected to the waste water container 46. The atomization pump 25 and the water inlet pump 21 are turned on, and the cleaning liquid is added to the water tank, the spray nozzle 30 and the pipeline for cleaning. When cleaning, the external circulation method during mixing can also be used to clean the liquid storage tank 15. After cleaning, the left cleaning valve 6 and the right cleaning valve 8 are connected to the backflush valve 31 through the hose 16, and the water pump 21 is turned on to rinse the outside of the spray nozzle 30, thereby achieving a comprehensive cleaning of the atomization device.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
