Description

Technical Field

[0001] The invention relates to the technical field of agricultural irrigation, and in particular to a water-fertilizer integrated irrigation machine for corn irrigation. Background Art

[0002] Conventionally, in the process of agricultural production, crops need to be fertilized. The fertilization process is generally carried out through a water-fertilizer integrated irrigation device, which mainly includes three steps: proportioning and adding, stirring and mixing, and fertilizer discharge and irrigation. Among them, the stirring and mixing link needs to make the fertilizer particles fully dissolved in water, so the efficiency of the stirring and mixing link will directly affect the fertilization efficiency. The commonly used water-fertilizer production equipment is a stirring tank. After adding fertilizer particles and water to the stirring tank in a certain proportion, the fertilizer particles are dissolved in water by rotating the stirring blade, thereby making water-fertilizers of different concentrations. Since some environments have high requirements for water-fertilizer concentration, a large amount of fertilizer particles will be added to the stirring tank when proportioning. The fertilizer particles will be deposited in large quantities at the bottom of the stirring tank under the action of gravity, affecting the dissolution efficiency of the fertilizer particles. Especially when the fertilizer particles are large, due to the large dead weight of the fertilizer particles, it is difficult to suspend them in water and fully contact them with water by stirring, further reducing the dissolution efficiency.

DETAILED DESCRIPTION

[0038] The present embodiment discloses a water-fertilizer integrated irrigation machine for corn irrigation, including a fertilizer dissolving mechanism for water-fertilizer mixing, a pipe laying mechanism before irrigation, a pipe collecting mechanism after irrigation, and a cleaning mechanism for collecting the pipes. The water-fertilizer integrated irrigation machine in the present embodiment can provide water and fertilizer supply for corn for large-scale planting; the pipe laying mechanism can be used to lay a hose for drip irrigation on the corn ridge; and the hose for drip irrigation can also be recycled and reused by using the pipe collecting mechanism.

[0039] In this embodiment, when in use, first, before irrigation, the hose 800 used for irrigation is laid along the corn ridge using the pipe laying mechanism; then the fertilizer is dissolved and transported using the fertilizer dissolving mechanism; finally, the pipe is collected using the pipe collecting mechanism; and during the process of collecting the pipe, the cleaning mechanism is used to clean the two side walls of the water pipe.

[0040] In this embodiment, Figure 2 As shown, the fertilizer dissolving mechanism includes a dissolving tank 100, a guide hopper 300 installed on the top of the dissolving tank 100, a stirring mechanism installed in the dissolving tank 100, and a water pump 400 connected to the dissolving tank 100; wherein the water pump 400 includes a water inlet pipe 401 connected to a water source, and a water inlet pipe 402 for conveying water and dissolving fertilizer; wherein the water inlet pipe 402 is connected to the interior of the dissolving tank 100 through a multi-way and branch pipe 4031; and an electromagnetic valve I 4031 is installed on the branch pipe 4031.

[0041] In this embodiment, the bottom of the dissolving tank 100 is connected to the water inlet pipe 401 through a liquid guide pipe 501, and an injection pump 500 for providing conveying power and a solenoid valve II 502 for controlling opening and closing are installed on the liquid guide pipe 501; a screening net 302 is installed at the bottom of the guide hopper 300, and the screening net 302 is arranged in an arc shape, and a material distribution auger 301 is installed in the guide hopper 300 and above the screening net 302; the rotating surface of the material distribution auger 301 is in contact with the screening net 302, and the material distribution auger 301 is driven to rotate by a reciprocating motor.

[0042] In this embodiment, the stirring mechanism includes a stirring shaft 300 installed inside the dissolving tank 100, a stirring blade 302 and a scraper 301 installed on the stirring shaft 300, and a stirring motor 200 driving the stirring shaft 300 to rotate; wherein the scraper 301 is in contact with the bottom surface of the dissolving tank 100; a liquid level sensor 101 is installed in the dissolving tank 100; the liquid level sensor 101 includes a minimum liquid level transmitter and a maximum liquid level transmitter; wherein flow valves are respectively installed on the water inlet pipe 401 and the liquid guide pipe 501.

[0043] The method of using this embodiment is as follows: first, the fertilizer solution needs to be prepared, and then the fertilizer solution is diluted with the water pump 400 for transportation. Specifically, the electromagnetic valve I 4031 needs to be controlled to be opened, and the electromagnetic valve II 502 and the injection pump 500 need to be closed; the required fertilizer is fed into the dissolution tank 100 through the guide hopper 300, and the required water is fed into the dissolution tank 100 through the water pump 400 and the branch pipe 4031, and the water and fertilizer are dissolved, stirred and mixed by the stirring mechanism. After the fertilizer is completely dissolved, the electromagnetic valve I 4031 is closed, and the electromagnetic valve II 502 and the injection pump 500 are opened, and the water after the fertilizer is dissolved is introduced into the water inlet pipe 401 through the liquid guide pipe 501, and the water pump 400 is used to transport and distribute the fertilizer.

[0044] The liquid level sensor 101 includes a minimum liquid level transmitter and a maximum liquid level transmitter. The liquid level sensor 101 is used to detect the liquid level of the dissolving tank 100 in real time, and then send it to the controller to control the solenoid valve I 4031 and the injection pump 500 respectively.

[0045] In the prior art, when fertilizer is used, it is easy to clump during storage or transportation. If it is directly put into the dissolving tank 100, it is easy to be insufficiently dissolved, and then the water pump is damaged during subsequent transportation. The reciprocating motor (specifically, a stepping motor) drives the distribution auger 301 to reciprocate, so that larger pieces of fertilizer are broken and leak into the dissolving tank 100 through the screening net 302 to improve the dissolution efficiency of the fertilizer.

[0046] In this embodiment, Figure 3 and Figure 4 As shown, the pipe laying mechanism includes a remote control vehicle 600, a support 603 installed on the remote control vehicle 600, a reel 604 installed on the support 603 through a bearing, and a locking and positioning mechanism installed on the remote control vehicle 600.

[0047] The locking and positioning mechanism includes a waterproof bracket 700, a positioning telescopic cylinder 702 installed on the top of the waterproof bracket 700, a U-shaped seat 703 connected to the telescopic end of the positioning telescopic cylinder 702, a pressure roller 704 installed in the U-shaped seat 703, and a pressure roller 705 installed in the waterproof bracket 700 and located below the pressure roller 704; a guide rod passing through the top of the waterproof bracket 700 is installed on the top of the U-shaped seat 703; a reserved groove 701 is opened on the side wall of the waterproof bracket 700 for facilitating the passage of the hose 800; and two pressure rollers 705 for clamping the hose 800 are installed below the pressure roller 704.

[0048] During use, the length of the ridge of the corn field is not necessarily compatible with the length of the hose 800 carried by the pipe laying mechanism; if the hose 800 is relatively short, an extension tube can be added; but if the carried hose 800 is shorter than the ridge, it is necessary to use the locking and positioning mechanism to lock the hose 800 to prevent it from being extended too long and affecting the irrigation efficiency; in addition, it is not convenient to lay the hose in a reciprocating turning manner, which will affect the subsequent automatic pipe collection.

[0049] In the present embodiment, specifically, when the length of the hose 800 reaches the required requirement, the U-shaped seat 703 can be pressed down by controlling the telescopic end of the positioning telescopic cylinder 702, so that the pressure roller 704 installed in the U-shaped seat 703 cooperates with the pressure roller 705 to clamp the passing hose 800 to prevent water from being further transported to the rear end; at the same time, the waterproof bracket 700 can also prevent the atomized water from being sprayed onto the remote control car 600.

[0050] In this embodiment, a plurality of traveling wheels 601 are installed at the bottom of the remote control car 600, and an electric control system 602 and a battery are also installed on the remote control car 600; the traveling wheels 601 are Mecanum wheels; a plurality of cameras are also installed on the remote control car 600 to facilitate remote control position identification; a crank or a reduction motor for driving the unwinding drum 604 to rotate is installed on the support 603; under normal circumstances, the unwinding drum 604 is automatically driven to unwind the hose 800 through the movement of the remote control car 600; in this embodiment, when rewinding after irrigation, it is necessary to cooperate with the tube retracting mechanism to unwind the hose 800 on the unwinding drum 604; and the end of the hose 800 needs to be opened to facilitate the discharge of water accumulated in the tube.

[0052] When in use, the driving motor 1002 drives the supporting inner shell of the slewing bearing 1005 to rotate, and then drives the winding drum 1000 fixedly connected to the supporting inner shell to rotate, so as to realize the winding of the hose 800.

[0053] In the present embodiment, the winding drum 1000 comprises a rotating drum 1001; a clamping seam is provided on the rotating drum 1001 for facilitating the embedding of the hose 800, and a plurality of threaded holes are provided on the inner wall of the rotating drum 1001, wherein a protective cover 1006 is inserted at the end of the rotating drum 1001; wherein the protective cover 1006 comprises a sleeve that can be inserted into the rotating drum 1001 and a hollow limiting disk vertically connected to the sleeve; screw holes corresponding to the threaded holes are provided in the sleeve, and the sleeve is locked and connected to the rotating drum 1001 by a locking bolt 1007; a limiting block 1008 that can be axially inserted into the clamping seam is installed on the outer wall of the sleeve.

[0054] In this embodiment, when in use, the end of the hose 800 has a pipe fitting that is threaded with the water outlet pipe 402 of the water outlet pump; in this embodiment, in order to avoid the trouble of disassembly.

[0055] A snap joint is provided on the rotating drum 1001 for facilitating the insertion of the hose 800.
