Description

Technical Field

[0001] The present invention relates to the technical field of sprinkler irrigation devices, and particularly to a multi-functional water-saving sprinkler irrigation method for agricultural planting. Background Technique

[0002] Agricultural planting is a social production sector that utilizes the life functions of plants and obtains food, non-staple foods, feeds, and industrial raw materials through artificial cultivation. In agricultural planting, it is necessary to water, spray fertilizers, and spray pesticides on plants. With the development of science and technology, there are various sprinkler irrigation devices on the market at present. However, the existing sprinkler irrigation devices have poor water-saving performance, resulting in a large amount of wasted water resources.

[0003] In the prior art, a patent document with the publication number of CN116686513A discloses a multi-functional water-saving sprinkler irrigation device and method for agricultural planting, including a sprinkler irrigation cylinder and a liquid inlet pipe penetrating through one side wall of the sprinkler irrigation cylinder. It further includes: two pull rod spray cylinders. The pull rod spray cylinders for sprinkler irrigation symmetrically penetrate through the two side walls of the sprinkler irrigation cylinder. The hose on the pull rod spray cylinder extends to the inner bottom plate of the sprinkler irrigation cylinder. A spring that automatically rebounds the pressing end is fixedly connected between the pressing end and the fixed end of the pull rod spray cylinder. The above device drives the sprinkler irrigation mechanism to rotate uniformly, thereby intermittently squeezing the pressing ends of the pull rod spray cylinders arranged on both sides, so that the pull rod spray cylinders spray the crops planted on the outside in small amounts and multiple times, facilitating the crops to better absorb the sprinkler irrigation liquid and preventing the crops from being difficult to absorb in time when too much liquid is sprayed. However, when the existing sprinkler irrigation device performs sprinkler irrigation operations, it is not convenient to improve the sprinkler irrigation coverage area and sprinkler irrigation efficiency per unit time of the sprinkler irrigation device through the cyclic conversion of the sprinkler irrigation method and form, the synchronous reciprocating vibration, reciprocating shaking, and reciprocating swinging modes of the sprinkler irrigation mechanism, and then achieve the water-saving purpose during the sprinkler irrigation process.

[0004] Based on this, the present invention provides a multi-functional water-saving sprinkler irrigation method for agricultural planting to solve the problems raised in the above background technique. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a multi-functional water-saving sprinkler irrigation method for agricultural planting to solve the problem that when the existing sprinkler irrigation device performs sprinkler irrigation operations, it is not convenient to improve the sprinkler irrigation coverage area and sprinkler irrigation efficiency per unit time of the sprinkler irrigation device through the cyclic conversion of the sprinkler irrigation method and form, the synchronous reciprocating vibration, reciprocating shaking, and reciprocating swinging modes of the sprinkler irrigation mechanism, and then achieve the water-saving purpose during the sprinkler irrigation process.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: A multi-functional water-saving sprinkler irrigation method for agricultural planting includes the following steps: SS01. Deployment: Deploy the sprinkler irrigation device in the agricultural planting plot. After the deployment of the sprinkler irrigation device, it is towed by an external towing device. After the deployment of the towing device, the water supply pipeline is connected to the sprinkler irrigation device through a pipeline and continuously supplies liquid to the sprinkler irrigation device. SS02. Sprinkler irrigation: During sprinkler irrigation, the towing device drives the sprinkler irrigation device to displace at a set speed, thereby realizing the sprinkler irrigation operation in the agricultural planting area. The sprinkler irrigation device includes a water shaking frame and a power cylinder connected to the water shaking frame. A shaking component for driving the water shaking frame to reciprocate up and down is installed at the bottom of the water shaking frame. A power shaft is rotatably installed on the inner wall of the power cylinder. A water-driven component is provided on the power shaft. A U-shaped frame is slidably installed on the water shaking frame. The water-driven component drives the U-shaped frame to reciprocate. Two symmetrically arranged sprinkler irrigation components are rotatably installed on the water shaking frame. The sprinkler irrigation component includes a rocking shaft. The rocking shaft is driven by the U-shaped frame and reciprocates. A rocking frame is installed on the top surface of the rocking shaft. A reciprocating pitching module is provided inside the rocking frame. The inner wall of the rocking frame is connected to a tail spray pipe that can reciprocate through the reciprocating pitching module. Hinge shafts are installed on both side surfaces of the tail spray pipe. Both hinge shafts are hinged to the rocking frame. The tail spray pipe is supplied with liquid through the water-driven component. A front spray pipe is slidably communicated with the inner wall of the tail spray pipe. A sprinkler irrigation stroke adjustment component is installed on the front spray pipe. The sprinkler irrigation stroke adjustment component drives the front spray pipe to reciprocate. A conversion cylinder is rotatably installed on the front spray pipe. A group of nozzles distributed in a circular array are communicated with the conversion cylinder. The type of each nozzle is different. A liquid permeable hole is opened at a position corresponding to the inside of the conversion cylinder on the front spray pipe. The conversion cylinder is driven by the sprinkler irrigation stroke adjustment component and rotates step by step.

[0007] The beneficial effects of the present invention are as follows: 1. When the present invention conducts sprinkler irrigation in the agricultural planting area, it can effectively improve the sprinkler irrigation coverage area and sprinkler irrigation efficiency per unit time of the device through the cyclic conversion of the sprinkler irrigation method and form, and the synchronous reciprocating shaking, reciprocating rocking and reciprocating swinging modes of the sprinkler irrigation mechanism, thereby realizing the purpose of water saving in the sprinkler irrigation process.

[0008] 2. In the present invention, during the irrigation water supply operation, the water-driven shaft is driven. After the water-driven shaft is driven, it then drives the second eccentric block and the stepping gear to rotate. Through the cooperation of the second eccentric block, the second pressing wheel and the elastic limiting member, the front spray pipe can reciprocate along the axis direction of the tail spray pipe. After the front spray pipe reciprocates, it then reciprocally adjusts the irrigation stroke of the nozzle. By increasing the irrigation stroke, the irrigation coverage area and irrigation efficiency of the device per unit time are improved. Through the setting of the stepping gear and the driven gear, the conversion cylinder can periodically rotate by 90°. When the conversion cylinder periodically rotates by 90°, it then periodically changes the type of nozzle used by the present irrigation device. Through the cyclic switching of the nozzle types, the irrigation method and irrigation form of the present irrigation device can be cyclically changed, ultimately achieving the improvement of irrigation uniformity and irrigation efficiency, so as to achieve the purpose of water conservation in the agricultural planting irrigation process.

[0009] 3. In the present invention, when performing agricultural irrigation operations, the power shaft rotates. After the power shaft rotates, it then drives the upper circular shaft to rotate. After the upper circular shaft rotates, it then drives the convex shaft to rotate. After the convex shaft rotates, through the cooperation of the first eccentric block, the first pressing wheel and the second elastic reset member, the water shaking frame can reciprocate up and down within a set stroke. After the water shaking frame reciprocates within the set stroke, it then realizes the up and down reciprocating movement and reciprocating water shaking during the irrigation spraying of the nozzle. By realizing the up and down reciprocating movement and reciprocating water shaking effect during the irrigation spraying of the nozzle, the irrigation uniformity of the present irrigation device per unit time is further improved through the water shaking spraying method.

[0010] 4. In the present invention, when the irrigation liquid is sent into the power cylinder and flows through the power cylinder, under the driving action of the power blade, the power shaft rotates in a set direction. After the power shaft rotates, through the setting of the semi-circular gear, the reciprocating toothed plate and the first elastic reset member, the U-shaped frame is driven to reciprocate within a set stroke. After the U-shaped frame reciprocates within the set stroke, it then drives the two active toothed plates to reciprocate. After the two active toothed plates reciprocate, through the meshing connection setting of the reciprocating toothed plate and the rocking gear, the rocking shaft is driven to reciprocate within a set angle range. By realizing the cyclic variable point irrigation effect within the 170° range of the present irrigation device, the irrigation coverage range and irrigation efficiency of the present irrigation device per unit time are effectively improved, and then the purpose of water conservation during irrigation is achieved.

[0011] On the basis of the above technical solutions, the present invention can also be improved as follows.

Shaking gears are installed on both of the two rocking shafts. The two active toothed plates are respectively in transmission connection with the two shaking gears. A lower circular shaft is rotatably connected to the inner wall of the water shaking frame. The lower circular shaft is in transmission connection with the power shaft through a first belt.

[0014] The beneficial effects of adopting the above further scheme are as follows: When performing agricultural sprinkler irrigation operations, the traction platform is towed by an external traction device to convert the sprinkler irrigation position. During the operation, the water diversion hose continuously delivers irrigation water through an external water supply device or a water supply pipeline. When the irrigation liquid is sent into the power cylinder and flows through the power cylinder, under the driving action of the power blades, the power shaft rotates in a set direction. After the power shaft rotates, through the settings of the semi-circular gear, the reciprocating toothed plate, and the first elastic reset component, the U-shaped frame is driven to reciprocate within a set stroke. After the U-shaped frame reciprocates within the set stroke, it then drives the two active toothed plates to reciprocate. After the two active toothed plates reciprocate, through the meshing connection setting between the reciprocating toothed plate and the shaking gear, the rocking shaft is driven to reciprocate within a set angle range; Specifically, by setting the number of teeth of the active toothed plate and the number of teeth of the shaking gear, finally, when the U-shaped frame reciprocates, the shaking gear can reciprocate within the range of ±85°; At the same time, through the double rocking shaft setting, the sprinkler irrigation device can cover 170° during the sprinkler irrigation operation; By realizing the cyclic variable-point sprinkler irrigation effect within the range of 170°, the sprinkler irrigation coverage range and sprinkler irrigation efficiency of the sprinkler irrigation device per unit time can be effectively improved, and then the purpose of water conservation during sprinkler irrigation can be achieved.

First teeth connected to the complete cone gear are evenly distributed on the tooth portions. The radian of the tooth portions is 60°. The U-shaped frame is arranged between the two rocking shafts.

[0017] The beneficial effect of adopting the above further scheme is that when performing agricultural sprinkler irrigation operations, the power shaft rotates. After the power shaft rotates, it ultimately drives the gear sleeve to rotate through the lower circular shaft. After the gear sleeve rotates, it drives the upper circular shaft to rotate. After the upper circular shaft rotates, due to the radian setting of the tooth portions on the truncated cone gear and the cooperation of the torsion spring, the front spray pipe and the tail spray pipe can reciprocally swing within ±60°. By realizing the reciprocal swinging effect of the front spray pipe and the tail spray pipe within ±60°, the sprinkling coverage area per unit time of the device and the sprinkler irrigation uniformity during sprinkler irrigation can be effectively improved. By improving the sprinkler irrigation coverage area and sprinkler irrigation uniformity per unit time, the purpose of water conservation during agricultural sprinkler irrigation can be achieved.

[0019] The beneficial effect of adopting the above further scheme is that when performing agricultural sprinkler irrigation operations, the power shaft rotates. After the power shaft rotates, it drives the upper circular shaft to rotate. After the upper circular shaft rotates, it drives the convex shaft to rotate. After the convex shaft rotates, through the cooperation of the first eccentric block, the first pressing wheel and the second elastic reset components, the water shaking frame can reciprocally move up and down within a set stroke. After the water shaking frame reciprocally moves within the set stroke, the reciprocating up and down movement and reciprocating water shaking during the sprinkler irrigation of the nozzle are realized. By realizing the reciprocating up and down movement and reciprocating water shaking effect during the sprinkler irrigation of the nozzle, the sprinkler irrigation uniformity per unit time of this sprinkler irrigation device can be further improved by the water shaking and sprinkling method.
