Description

TECHNICAL FIELD

[0001] The present application relates to the field of irrigation, in particular to a water-saving irrigation device with filtering function. BACKGROUND

[0002] When irrigation is carried out, if it is in a drought area, when the water flow enters the soil surface, a part of the irrigation water flow will be lost due to water evaporation. Most of the water pump connections used for irrigation do not have filtering mechanisms, which can easily cause the water pump or irrigation nozzle to be blocked. Cleaning the blockage requires operating time and increases unnecessary workload.

[0003] In addition, different crops require different amounts of irrigation water during different growth periods. For example, rice requires the most water, with early rice requiring about 180-230 cubic meters per mu and late rice requiring up to 230-320 cubic meters per mu. Wheat, corn, cotton and other dry crops generally require about 300 cubic meters of water per mu per year. Chinese cabbage, chives and other vegetables require about 200-500 cubic meters of water per mu. Therefore, when different varieties or different growth periods of crops are planted in the same planting area, the use of the same set of irrigation equipment is often limited by the amount of irrigation water.

[0051] In order for those skilled in the art to better understand the present application, the present application will be further clarified and completed by combining the following reference to the drawings and combining the embodiments. It should be noted that the features in the embodiments and examples in the present application can be combined with each other without conflict.

[0052] A typical embodiment of the present application provides a water-saving irrigation device with filtering function, as shown in Figure 1 , which comprises a serial hose 6 and an irrigation filtering mechanism 7 connected by the serial hose 6. The irrigation water is guided to different positions through the guide connection of the serial hose 6.

[0053] As shown in Figure 6 , the irrigation filtering mechanism 7 comprises a guide pipe 71, both sides of the guide pipe 71 are provided with guide interfaces 711, and the guide interfaces 711 are provided with valves 712.

[0054] The upper side of the guide pipe 71 is provided with an extension pipe 72, the guide pipe 71 and the extension pipe 72 are threadedly connected, and the connection between the guide pipe 71 and the extension pipe 72 is provided with a rubber gasket, which increases the sealing property of the guide pipe 71 and the extension pipe 72, and avoids water overflow.

[0055] As shown in Figure 9 , Figure 12 and Figure 13 , the top end of the extension pipe 72 is provided with a protection bin 7201, the top surface of the extension pipe 72 is provided with a top platform 7202, the top platform 7202 is provided with a driving motor 7203, and the output end of the driving motor 7203 is connected with a driving gear 7204. The side surface of the driving gear 7204 is connected with a guide gear 7205, and the driving gear 7204 and the guide gear 7205 are in meshing connection. The middle part of the guide gear 7205 is connected with a driving lead screw 7206, and the guide gear 7205 and the driving lead screw 7206 are in screw thread connection structure.

[0056] As shown in Figure 14 , the bottom end of the driving lead screw 7206 is connected with a guide plate 7209, the guide plate 7209 is provided with a mounting frame 7210, and the mounting frame 7210 is uniformly distributed with second filter plates 7211.

[0057] As shown in Figure 12 , the top end of the driving lead screw 7206 is provided with a top plate 7207, and the limit rod 7208 is installed between the top plate 7207 and the guide plate 7209; the limit rod 7208 and the top platform 7202 are in through sliding connection structure, and the driving lead screw 7206 and the protection bin 7201 are in through sliding connection.

[0058] When the drive gear 7204 rotates, it drives the guide gear 7205 to rotate. The thread in the middle of the guide gear 7205 meshes with the drive screw 7206. The drive screw 7206 is limited by the limit rod 7208. The drive screw 7206 moves vertically, causing the guide plate 7209 to move up and down. The mounting bracket 7210 installed on the guide plate 7209 also moves up and down accordingly, thereby causing the second filter plate 7211 on the mounting bracket 7210 to move in position. After the water source is filtered for a certain period of time, the second filter plate 7211, which comes into contact with the water first, is replaced by moving in position to ensure the effectiveness of filtration.
