Description

Technical Field

[0001] The invention belongs to the technical field of greening irrigation, and in particular relates to an irrigation device for greening engineering construction and an irrigation control method thereof. Background Art

[0002] During the construction of engineering projects, whether it is municipal engineering construction, housing construction or garden engineering construction, greening operations need to be carried out during the construction process. Greening is also one of the main parts of engineering construction. Greening construction requires replacing soil, planting green land, transplanting vegetation, and maintaining green land and vegetation. The existing greening irrigation devices used in engineering construction are generally irrigation vehicles, that is, an irrigation barrel is installed on the vehicle body, and then the liquid in the irrigation barrel is discharged through the pump body and sprayed onto the green vegetation to complete the spray irrigation treatment of the green land and vegetation. For example, a movable water conservancy engineering irrigation device proposed in the Chinese patent with announcement number CN219352371U includes a frame, a water tank, a fertilizer tank, a pipeline mechanism, a rear sprinkler mechanism and a multi-angle sprinkler mechanism. The frame is a vehicle with rollers at the bottom and a front A walking frame with a mop at the end is provided, and a bottom plate is provided on the frame. The bottom ends of the water tank and the fertilizer tank are mounted on the bottom plate in parallel through a bracket; the pipeline mechanism has an irrigation pipeline, a fertilization pipeline, a mixing chamber and a common discharge pipe, wherein the irrigation pipeline and the fertilization pipeline are respectively connected to the drainage outlets of the water tank and the fertilizer tank, and the irrigation pipeline and the fertilization pipeline are both provided with a pump body and a valve body; a mixing pipeline is provided at the rear end of the mixing chamber, and the mixing pipeline is connected to the irrigation pipeline and the fertilization pipeline, and the front end of the mixing chamber is connected to the rear sprinkler mechanism and the multi-angle sprinkler mechanism through the common discharge pipe. The utility model utilizes a premixing chamber, a pump, an irrigation pipe network and a sprinkler mechanism to realize the functions of irrigation, topdressing and spraying, and adopts a mobile frame, which is convenient to use.

[0003] Although the above-mentioned irrigation vehicle can carry out spray irrigation and maintenance of green vegetation with medicine and fertilizer, the sprayed medicine liquid is generally in the same level, and there is a phenomenon of missed spray irrigation. For the newly transplanted vegetation in the greening construction, the missed spraying and uneven spraying cause a waste of water and medicine resources, and also cause vegetation pests and diseases due to poor vegetation management, which affects the quality of the greening project and increases the construction cost of the greening project. Therefore, an irrigation device for engineering construction greening and an irrigation control method thereof are proposed, which can carry out three-dimensional spray irrigation on green transplanted vegetation.

[0031] The present invention provides an irrigation device for greening engineering construction, which has the following features compared with the prior art:

[0032] Beneficial effects:

[0033] 1. In the present invention, the first screw can be driven to rotate by a motor, and the first screw pushes the mounting plate threaded therewith to perform linear motion, thereby changing the eccentric distance of the mounting plate relative to the wheel until it reaches a preset position. At this time, the rotation of the wheel drives the vehicle body to move while pushing the pushing plate to drive the pushing frame to perform linear motion in the vertical direction. The pushing frame pushes the second piston plate to perform linear motion in the vertical direction in the third liquid chamber. At the same time, the pushing frame performing linear motion in the vertical direction pushes the second push rod to perform synchronous linear motion. The second push rod drives the second pushing column fixed thereon to slide along the second spiral groove provided in the second rotating cylinder. At this time, the second rotating cylinder performs vertical rotational motion, and the second rotating cylinder drives the second screw to perform vertical rotational motion through the transmission pair. The second screw pushes the first piston plate threaded therewith in the second liquid chamber The second piston plate that performs linear motion in the vertical direction performs linear motion in the second liquid chamber. At this time, the mixed liquid in the second liquid chamber is introduced into the third liquid chamber under the squeezing of the first piston plate. At this time, the second piston plate that performs linear motion in the vertical direction pushes the liquid into the installation cylinder. At this time, a part of the liquid enters the nozzle, and the other part of the liquid pushes the second fan blade to drive the nozzle to perform a rotational motion in the vertical direction. Since the nozzle is threadedly connected to the liquid collecting pipe, the nozzle can perform a spiral motion in the vertical direction. Since the pitches of the nozzles are different, the nozzles can drive the nozzles connected thereto to perform spiral motions at different speeds, that is, the nozzles can perform spraying treatments at different levels in the space, improve the spraying density of the mixed liquid, save water and medicine resources for greening construction and maintenance, and at the same time, the sprinkler irrigation efficiency is improved to ensure that the sprinkler irrigation and maintenance of transplanted vegetation in greening construction are more uniform and in place;

[0034] 2. The control system monitors the spray pressure of the mixed liquid and the viscosity of the mixed liquid in real time and obtains information through the pressure detection unit and the viscosity detection unit in the monitoring module, forms pressure F and viscosity P, and transmits them to the evaluation unit for evaluation. If at least one of them exceeds the corresponding first preset threshold, judgment information is formed. The evaluation unit obtains the pressure F and viscosity P, and performs dimensionless processing on them, and associates them to form a control coefficient PS. The obtained detection condition coefficient PS is transmitted to the judgment unit for comparison with the preset second preset threshold. If the detection condition coefficient PS is not within the range of the second preset threshold, a corresponding control instruction is formed to regulate the spray pressure of the mixed liquid and the viscosity of the mixed liquid until PS is within the threshold, so that the vegetation maintenance effect of the greening construction is better, the quality of the greening construction is avoided, and the cost of the greening construction is reduced.

The second liquid chamber 401 is connected to the first liquid storage tank 3 through a pipeline mixing mechanism 8. The second liquid chamber 401 is connected to the third liquid chamber 402 through a one-way valve (not shown) installed on the second liquid storage tank 4.

[0048] The spraying mechanism 6 is installed on the second liquid storage tank 4 and is connected to the third liquid chamber 402, and is used for spraying the liquid medicine in a three-dimensional manner;

The purpose of this arrangement is to guide the liquid in the third liquid chamber 402 into the ejection mechanism 6 for ejection processing;

[0053] See also Figure 4 Preferably, as another embodiment of the present invention, the pushing mechanism 7 includes a pushing plate 701, a pushing frame 702, a second piston plate 703 and a second valve member 704, the pushing frame 702 is hinged to the pushing plate 701 penetrating the vehicle body 1, one end of the pushing frame 702 extends into the third liquid chamber 402 and slidably cooperates with the second liquid storage tank 4, the second valve member 704 is embedded and fixedly connected to the second piston plate 703, the second piston plate 703 slidably cooperates with the third liquid chamber 402 and is fixedly connected to the pushing frame 702, and further includes:

[0054] A transmission assembly 706, mounted on the second liquid storage tank 4, for driving the liquid transmission mechanism 5 to move; and

[0055] An adjusting assembly 705, mounted on the wheel 2, for adjusting the movement speed of the second piston plate 703;

[0056] See also Figures 1 to 5 Specifically, the liquid transmission mechanism 5 includes a first piston plate 501 and a first valve member 502. The first piston plate 501 is slidably disposed in the second liquid chamber 401. The first valve member 502 is embedded and installed on the first piston plate 501. The first piston plate 501 is transmission-connected to the push frame 702 through a transmission assembly 706. The liquid transmission mechanism 5 also includes:

[0057] The liquid mixing component 503 is installed in the second liquid chamber 401 and is used to promote the circulation of the liquid in the second liquid chamber 401;

[0058] The liquid mixing assembly 503 includes a circulation cylinder 5031 and a first fan blade 5032. The circulation cylinder 5031 is fixedly connected to the second liquid storage tank 4. The top of the circulation cylinder 5031 is provided with a first circulation hole 50311. The lower side of the circulation cylinder 5031 is provided with a second circulation hole 50312. The circulation cylinder 5031 also includes:

[0059] The driving assembly 5033 is used to drive the first fan blade 5032 to rotate in the vertical direction in the circulation cylinder 5031. The driving assembly 5033 includes a first rotating cylinder 50331 and a first push rod 50332. The first rotating cylinder 50331 on which the first fan blade 5032 is fixedly connected is rotatably connected to the second liquid storage tank 4. One end of the first push rod 50332 is fixedly connected to the first piston plate 501, and the other end of the first push rod 50332 extends into the first rotating cylinder 50331 and is fixedly connected to a first pushing column (not marked in the figure) that slidably cooperates with a first spiral groove (not marked in the figure) opened in the first rotating cylinder 50331. The first piston plate 501 is driven by the transmission assembly 706 to perform a reciprocating motion in the vertical direction along the second liquid chamber 401, that is, to squeeze the liquid in the second liquid chamber 401 into the third liquid chamber 402. At this time, the first piston plate 501 pushes the first push rod 50332 to perform a reciprocating linear motion in the vertical direction along the length direction of the first rotating cylinder 50331. At this time, the first push rod 50332 pushes the first push column fixed thereon to slide along the first spiral groove provided on the first rotating cylinder 50331, that is, to cause the first rotating cylinder 50331 to perform a rotational motion in the vertical direction. The first rotating cylinder 50331 drives the first fan blade 5032 to rotate in the circulation cylinder 5031. At this time, driven by the first fan blade 50311, a pressure difference is generated on the liquid on the upper and lower sides of the first fan blade in the circulation cylinder 5031. At this time, the first fan blade 5032 sucks the liquid in the second liquid chamber 401 from the first circulation hole 50311 into the circulation cylinder 5031 and draws it out from the second circulation hole 50312. The liquid in the second liquid chamber 401 is discharged internally, so as to promote the internal circulation of the liquid in the second liquid chamber 401, and prevent the precipitation of the mixed liquid medicine (the water and liquid medicine in the first liquid storage tank 3 are mixed by the pipeline mixing mechanism 8 and then introduced into the first liquid chamber 401 in the second liquid storage tank 4 for storage. If the vehicle body 1 stops working or the central axis of the mounting plate 7053 in the adjustment component 705 coincides with the central axis of the wheel 2 connected thereto, that is, the second piston plate 703 does not perform linear motion in the third liquid chamber 402, at this time, if there is no temporary storage in the second liquid chamber 401, the mixture of water and liquid medicine will directly remain in the third liquid chamber 402, and there is a risk of precipitation. If the mixture of water and liquid medicine precipitates, the concentration of the liquid medicine sprayed by the spraying mechanism 6 will change, which will have an adverse effect on the sprinkler irrigation object. Therefore, the purpose of setting the second liquid chamber 401 when the third liquid chamber 402 exists is to temporarily store the mixture of water and liquid medicine, and to provide a space for stirring and mixing the mixture again when the mixture of water and liquid medicine precipitates).

The purpose of this arrangement is to mix the liquid in the first liquid storage tank 3 and the liquid medicine and introduce them into the second liquid cavity 401.

[0068] In the embodiment of the present invention, the first screw rod 7052 is driven to rotate by a motor, and the first screw rod 7052 pushes the mounting plate 7053 threadedly connected thereto to perform linear motion, thereby changing the eccentric distance of the mounting plate 7053 relative to the wheel 2 until it reaches a preset position.

The pushing frame 702 pushes the second piston plate 703 to perform linear motion in the vertical direction in the third liquid chamber 402. At the same time, the pushing frame 702 performing linear motion in the vertical direction pushes the second push rod 7061 to perform synchronous linear motion. The second push rod 7061 drives the second pushing column fixed thereon to slide along the second spiral groove provided in the second rotating cylinder 7062. At this time, the second rotating cylinder 7062 performs vertical rotational motion. The second rotating cylinder 7062 drives the second screw rod 7063 to perform vertical rotational motion through the transmission pair 7064. The second screw rod 7063 pushes the second screw rod 7063 threadedly connected thereto to perform vertical rotational motion. The first piston plate 501 connected by the thread performs linear motion in the vertical direction in the second liquid chamber 401. At this time, the mixed liquid in the second liquid chamber 401 (the mixed liquid in the second liquid chamber 401 is introduced from the first liquid storage tank 3 through the pipeline mixing mechanism 8) is introduced into the third liquid chamber 402.
