DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Referring to Figures 1 - 6 , the present invention provides an organic fertilizer application device with adjustable fertilization amount, including:

[0038] A material pipe 1, with a pore opening and closing mechanism and a nozzle 2 provided at the liquid outlet end;

[0039] A push plate 3, slidably arranged in the material pipe 1, and the push plate 3 is used to push the liquid fertilizer in the material pipe 1 towards the pore opening and closing mechanism;

[0040] An adjusting rod 4, rotatably arranged between the push plate 3 and the pore opening and closing mechanism. Multiple sections of sequentially connected and spiral adjusting chutes 5 are provided on the adjusting rod 4. The pitch of the multiple sections of adjusting chutes 5 decreases sequentially towards the direction of the pore opening and closing mechanism. A shifting rod 6 connected to the push plate 3 is slidably engaged in the multiple sections of adjusting chutes 5. One end of the adjusting rod 4 towards the pore opening and closing mechanism is provided with a propeller 7;

[0041] A telescopic member 8, arranged on the material pipe 1, and the output end of the telescopic member 8 is connected to the push plate 3 through a position adjusting mechanism.

[0042] By controlling the opening amplitude of the liquid outlet end of the material pipe 1 through the pore opening and closing mechanism, while adjusting the opening amplitude of the material pipe, the initial position of the push plate 3 in the material pipe 1 is adjusted through the position adjusting mechanism, so that the push plate 3 drives the shifting rod 6 to move synchronously, and the position of the shifting rod 6 on the multiple sections of adjusting chutes 5 is adjusted. When the telescopic member 8 pushes the push plate 3, the push plate 3 pushes the liquid fertilizer towards the pore opening and closing mechanism. At the same time, the shifting rod 6 cooperates with the adjusting chute 5, causing the adjusting rod 4 to rotate, so that the propeller 7 rotates at the pore opening and closing mechanism. And the pitch of the multiple sections of adjusting chutes 5 decreases sequentially towards the direction of the pore opening and closing mechanism, which can be matched with different opening amplitudes. When the fertilization amount is large, the rotation speed of the propeller 7 is increased, and when the fertilization amount is small, the rotation speed of the propeller 7 is synchronously reduced, improving the flow stability of the liquid fertilizer in the material pipe 1 at different opening amplitudes, thereby effectively controlling the liquid outlet efficiency of the liquid fertilizer.

[0043] The propeller 7 improves the flow efficiency of the water flow through an optimized hydrodynamic design. Reasonably selecting the number of blades can ensure sufficient thrust and improve the propulsion efficiency at the same time.

[0044] In an embodiment of the present invention, the position adjusting mechanism includes:

[0045] A first connecting frame 9, connected to the output shaft of the telescopic member 8;

[0046] A threaded sleeve 10, rotatably connected to the first connecting frame 9. A driven gear 11 is fixedly connected to the threaded sleeve 10. A screw rod 12 is in threaded fit with the threaded sleeve 10, and the screw rod 12 is fixedly connected to the pushing plate 3;

[0047] A limit telescopic rod 13, fixedly connected between the pushing plate 3 and the first connecting frame 9;

[0048] A rotating rod 14 is rotatably arranged in the material pipe 1 through a driving member 15. A long gear 16 is arranged on the rotating rod 14, and the long gear 16 meshes with the driven gear 11.

[0049] The telescopic member 8 pushes the first connecting frame 9 to push the pushing plate 3, and drives the rotating rod 14 to rotate through the driving member 15, so that the rotating rod 14 drives the long gear 16 to rotate. Then, the long gear 16 drives the driven gear 11 meshing with it to rotate, so that the driven gear 11 drives the threaded sleeve 10 to rotate. Due to the threaded fit between the threaded sleeve 10 and the screw rod 12, and at the same time, the limit telescopic rod 13 guides and supports the pushing plate 3, the screw rod 12 extends and retracts in the threaded sleeve 10, so as to adjust the interval between the pushing plate 3 and the first connecting frame 9, thereby adjusting the initial position of the pushing plate 3, and further adjusting the initial position of the dial rod 6 in the adjustment chute 5.

[0050] Furthermore, the rotating rod 14 penetrates through the pushing plate 3 and has a sliding and rotatable assembly relationship with the pushing plate 3, and the two are sealed by a sealing ring.

[0051] In an embodiment of the present invention, the pore opening and closing mechanism includes:

[0052] A fixing plate 17, fixedly connected to the material pipe 1. A plurality of first discharge ports 18 are opened on the fixing plate 17;

[0053] An opening and closing plate 19 abuts against one side of the fixing plate 17. The opening and closing plate 19 is fixedly connected to the rotating rod 14. A plurality of second discharge ports 20 are arranged on the opening and closing plate 19, and the plurality of second discharge ports 20 correspond to the plurality of first discharge ports 18 one by one.

[0054] When adjusting the initial position of the push plate 3 through the rotating rod 14, the opening and closing plate 19 is synchronously driven to rotate. The second discharge port 20 on the opening and closing plate 19 cooperates with the first discharge port 18 on the fixed plate 17 to adjust the coincidence degree between the second discharge port 20 and the first discharge port 18, so that gaps with different areas are formed between the second discharge port 20 and the first discharge port 18, thereby adjusting the opening amplitude of the material pipe 1.

[0055] In an embodiment of the present invention, a plurality of through holes 21 are formed in the push plate 3, and plugging columns 22 are inserted into the through holes 21. The plurality of plugging columns 22 are fixedly connected through a second connecting frame 23. The second connecting frame 23 is located on one side of the push plate 3 close to the pore opening and closing mechanism. A plurality of springs 24 are fixedly connected between the second connecting frame 23 and the push plate 3. A water pump 26 is arranged on the material pipe 1, and the liquid outlet end of the water pump 26 is located on the side of the push plate 3 away from the pore opening and closing mechanism.

[0056] By arranging the springs 24 and the plugging columns 22, when the push plate 3 pushes the liquid fertilizer towards the nozzle 2, the plugging columns 22 block the through holes 21 to push the liquid fertilizer. When the push plate 3 resets, the water pump 26 pumps the liquid fertilizer into the material pipe 1, and the liquid fertilizer is pushed by the pumping force of the water pump to impact the plugging columns 22, so that the plugging columns 22 are separated from the through holes 21, so that the liquid fertilizer flows through the through holes 21 into the side of the push plate 3 close to the pore opening and closing mechanism.

[0057] The spring 24 is preferably a helical spring. When the helical spring is stretched or compressed, the steel wire itself is not stretched or compressed, and elastic deformation is achieved by changing the bending degree. It has the advantages of compact structure, light weight, small floor area, and does not require lubrication and cleaning, and has low maintenance cost.

[0058] In an embodiment of the present invention, a plurality of support rods 25 are fixedly connected to the second connecting frame 23. The support rods 25 penetrate through the push plate 3 and are slidably matched with the push plate 3 to improve the sliding stability between the second connecting frame 23 and the push plate 3. The support rods 25 and the push plate 3 are sealed through a sealing ring.

[0059] In an embodiment of the present invention, an assembly frame 27 is arranged on the material pipe 1 for connecting with an external structure.

[0060] In an embodiment of the present invention, the opening and closing plate 19 includes a fixed layer 191 fixedly connected to the rotating rod 14 and a sealing layer 192 abutted against the fixed plate 17. The sealing layer 192 is an elastic structure, which improves the sealing effect between the opening and closing plate 19 and the fixed plate 17, avoids the leakage of liquid fertilizer through the gap, and improves the control accuracy of the fertilization amount.

[0061] In an embodiment of the present invention, the telescopic member 8 is a cylinder, preferably a waterproof cylinder. The waterproof cylinder adopts special sealing materials and structures, which can effectively prevent moisture from entering the interior of the cylinder, ensuring its stable operation in a humid or water mist environment.

[0062] In an embodiment of the present invention, the driving member 15 is a motor, preferably a waterproof motor. The outer shell of the waterproof motor usually adopts waterproof materials such as rubber or plastic, and waterproof grooves, waterproof covers and other structures are added to the outer shell to prevent moisture from entering the interior of the motor, thereby protecting the motor from water damage.

[0063] Furthermore, it further includes a controller and a power supply arranged on the material pipe 1, both of which are connected to the telescopic member 8 and the driving member 15. The controller controls the actions of the motor and the cylinder simultaneously through precise signal processing and power output.

It is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0065] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
