Description

Technical Field

[0001] This utility model relates to the field of rice cultivation, specifically an automatic irrigation device for rice cultivation. Background Technology

[0002] China is one of the origins of rice. In southern China, farmland is predominantly paddy fields, with rice being the primary grain crop. Rice is an important cereal widely cultivated in tropical Asia, with southern China being the main rice-producing region, and it is also grown in some northern provinces such as Heilongjiang, Jilin, and Liaoning. Rice is mainly divided into two subspecies: indica and japonica. During rice cultivation, it is crucial to maintain stable water levels within the paddy fields to meet the rice's water needs for growth. Irrigation canals are often constructed near the paddy fields. When water is scarce, the water inlets between the paddy fields can be opened, allowing water from the canals to flow into the paddy fields, thus irrigating them.

[0003] Current automatic irrigation devices for rice cultivation, as described in patent CN221082283U, include two rods, each with a lifting device at its top and a rotating device between them. Each lifting device has a switch, which includes a connecting block. A rotating plate is movably connected to the inner side of the connecting block, and a float is fixedly connected to the front side of the rotating plate. A start button is located below the rotating plate.

[0004] Regarding the aforementioned technologies, the inventors propose that this automatic irrigation device for rice cultivation uses a pole fixed to the paddy field soil. When the water level in the paddy field drops, the float and rotating plate move downwards, triggering the start button to automatically activate the water pump for irrigation. During operation, motor one drives the threaded screw to rotate, raising the outer connecting plate to a preset height; subsequently, motor two drives the rotating shaft to move left and right. External water is transported through water pipes and finally evenly sprayed onto the farmland by nozzles. Because an electric water pump is used for irrigation, a power cable needs to be installed near the paddy field, resulting in high operating costs. This electricity demand significantly increases the overall investment cost of the automatic irrigation system. Utility Model Content

[0005] The purpose of this invention is to provide an automatic irrigation device for rice cultivation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic irrigation device for rice cultivation, comprising:

[0008] An irrigation mechanism, comprising a fixed frame, a rotating shaft rotatably connected inside the fixed frame, a baffle fixedly connected to the bottom of the rotating shaft, and a U-shaped baffle fixedly connected inside the fixed frame, the U-shaped baffle abutting against one side of the baffle;

[0009] An adjustment mechanism is provided, comprising an adjustment screw threaded through the interior of the rotating shaft, wherein a float is rotatably connected to one end of the adjustment screw near the U-shaped retaining frame.

[0010] As a further embodiment of this utility model: the baffle has an overflow port inside, and the overflow port is located on the side of the baffle close to the rotating shaft.

[0011] As a further embodiment of this utility model: a filter box is fixedly connected to the side of the fixed frame away from the float, and a connecting plate is fixedly connected to one side of the filter box, and the connecting plate is fixedly connected to the fixed frame.

[0012] As a further embodiment of this utility model: a water tank is fixedly connected to the side of the fixed frame away from the filter box, and the water tank corresponds to the float.

[0013] As a further embodiment of this utility model: a filter screen is fixedly connected to the top of the water tank, the filter screen is fixedly connected to the fixed frame, a top frame is fixedly connected to the top of the filter screen, and the top frame is fixedly connected to the fixed frame.

[0014] As a further embodiment of this utility model: the rotating shaft has sliding rods that slide symmetrically through it, and one end of each of the two sets of sliding rods is fixedly connected to the float.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-mentioned structure, this utility model, through the cooperation of the rotating shaft, adjusting screw, baffle and float, allows the float to move downward under its own gravity when the water level in the paddy field drops. At the same time, the adjusting screw and sliding rod drive the rotating shaft and baffle to rotate, causing the baffle to disengage from the U-shaped baffle frame. This allows water inside the irrigation canal to flow into the paddy field through the inside of the fixed frame, thus achieving automatic irrigation of the paddy field without the need for laying cables, thereby reducing the cost of automatic irrigation of paddy fields.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4 An automatic irrigation device for rice cultivation includes an irrigation mechanism 1. The irrigation mechanism 1 includes a fixed frame 101, which is installed at the water inlet of the paddy field so that water from the irrigation canal can flow into the paddy field through the interior of the fixed frame 101. A filter box 205 is fixedly connected to the side of the fixed frame 101 away from the float 203. A connecting plate 204 is fixedly connected to one side of the filter box 205. The connecting plate 204 is fixedly connected to the fixed frame 101. The filter box 205 is used to filter the water flowing into the fixed frame 101 from the irrigation canal to reduce the probability of debris entering the interior of the fixed frame 101.

[0025] A rotating shaft 102 is rotatably connected inside the fixed frame 101. A baffle 103 is fixedly connected to the bottom of the rotating shaft 102. A U-shaped baffle 105 is fixedly connected inside the fixed frame 101. The U-shaped baffle 105 abuts against one side of the baffle 103. The baffle 103 is designed to prevent water from flowing into the paddy field when it abuts against the U-shaped baffle 105 during rotation. An overflow port 104 is provided inside the baffle 103. The overflow port 104 is located on the side of the baffle 103 near the rotating shaft 102. The overflow port 104 is designed to allow water from the paddy field to overflow into the irrigation canal, thereby reducing the probability of rice dying from excessively high water levels in the paddy field.

[0026] The regulating mechanism 2 includes an regulating screw 201 threaded through the interior of the rotating shaft 102. A float 203 is rotatably connected to one end of the regulating screw 201 near the U-shaped baffle 105. The float 203 is designed to float on the surface of the paddy field using its own buoyancy. When the water level in the paddy field drops, the float 203 drops with the water level, thereby driving the rotating shaft 102 and the baffle 103 to rotate through the regulating screw 201. This causes the baffle 103 to disengage from the U-shaped baffle 105, allowing the water in the irrigation canal to be filtered through the filter box 205 and then flow into the paddy field through the interior of the fixed frame 101, thus achieving automatic irrigation of the paddy field. When the regulating screw 201 rotates, it can drive the float 203 to move up and down, thereby adjusting the water level in the paddy field that needs irrigation.

[0027] A sliding rod 202 is symmetrically slidably passed through the interior of the rotating shaft 102. One end of each sliding rod 202 is fixedly connected to the float 203. The sliding rod 202 guides the movement of the float 203. A water tank 206 is fixedly connected to the side of the fixed frame 101 away from the filter box 205. The water tank 206 corresponds to the float 203 and is used to hold water, allowing it to be buried below the soil level of the paddy field to provide sufficient space for the float 203 to move. A filter screen 207 is fixedly connected to the top of the water tank 206 and to the fixed frame 101. A top frame 208 is fixedly connected to the top of the filter screen 207 and to the fixed frame 101. The filter screen 207 filters the water flowing into the water tank 206, reducing the probability of debris from the paddy field falling into the water tank 206.

[0028] In use, the fixed frame 101 is fixed at the water inlet of the paddy field, and the filter box 205 is placed close to the side of the irrigation canal, while the water tank 206 is placed close to the side of the paddy field. Under the buoyancy of the float 203, the sliding rod 202, the rotating shaft 102, and the baffle 103 are rotated, allowing the baffle 103 to rotate until it abuts against the U-shaped baffle frame 105, thus preventing water from the irrigation canal from flowing into the paddy field. When the water level in the paddy field drops, the float 203 drops with the water level, thereby driving the rotating shaft 102 and the baffle 103 to rotate through the adjusting screw 201. This causes the baffle 103 to disengage from the U-shaped baffle frame 105, allowing the water in the irrigation canal to be filtered through the filter box 205 and then flow into the paddy field through the interior of the fixed frame 101, thus achieving automatic irrigation of the paddy field.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
