Description

Technical Field

[0001] The utility model relates to the technical field of irrigation devices, in particular to a water-fertilizer integrated irrigation device for rice planting. Background Art

[0002] The use of integrated water and fertilizer irrigation technology in rice planting is a modern agricultural management method that combines two important links, irrigation and fertilization, to optimize the growth environment of rice. Integrated water and fertilizer irrigation technology refers to the process of rice planting, through a scientific water and fertilizer management system, according to the needs of different growth stages of rice, to supply water and nutrients to rice in the most optimized proportion and way, so as to achieve the purpose of increasing yield, improving quality and reducing environmental pollution.

[0003] In the prior art, such integrated water-fertilizer irrigation devices generally use water from nearby ponds and rivers when taking water, and generally use filter elements to filter impurities in the water in order to filter the water source. However, the position of the water intake of such equipment in the prior art remains unchanged. If the water intake is too low, it is easy to inhale mud and sand. If the water intake is too high, it is easy to inhale aquatic plants and other substances. Therefore, in order to address this problem, an improved integrated water-fertilizer irrigation device for rice planting is needed. Utility Model Content

[0004] The utility model aims to provide a water-fertilizer integrated irrigation device for rice planting to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, a motor is fixedly provided on the upper end of the fixed frame, and a stirring rod is fixedly provided on the output shaft end of the motor via a coupling. The stirring rod is driven to rotate by the motor, so that the water and fertilizer inside the mixing barrel can be mixed.

[0007] Preferably, a second pump body is provided on one side of the mixing barrel, a second suction tube is provided between the second pump body and the mixing barrel, and a drip irrigation pipe is fixedly provided on one side of the surface of the second pump body. Water and fertilizer inside the mixing barrel can be pumped out through the second pump body, and then drip irrigation is carried out into the field through the drip irrigation pipe.

[0008] Preferably, the liquid inlet end of the second pump body and the second liquid suction pipe are connected to each other, and the liquid outlet end of the second pump body and the inside of the drip irrigation pipe are connected to each other.

[0009] Preferably, a twisting block is fixedly provided at the lower end of the screw rod, and the screw rod can be conveniently rotated by the twisting block.

[0010] Preferably, a through groove is provided on the outer surface of the lower end of the float chamber, through which the interior of the float chamber can change according to the movement of the piston, so that water can enter the float chamber to varying degrees. If there is no through groove, the buoyancy of the float chamber will basically remain unchanged no matter how the piston moves.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. After the filter element of the utility model is put into water, it can float in the middle of a pond or a river under the action of the floating cavity, so it is not easy to absorb mud and water plants, thereby effectively preventing the filter element from being blocked; thereby improving the use effect of the device.

[0013] 2. The floating depth of the device of the utility model can be changed as needed. The screw is rotated to drive the piston to move inside the float chamber, so that the position of the vacuum in the float chamber changes, so as to change the buoyancy generated after the float chamber enters the water. When the buoyancy of the float chamber of the device becomes smaller, it can drive the longer first suction tube to sink into the water. It can stop until the total buoyancy of the filter element, the float chamber, and the first suction tube is balanced with its own gravity. In this way, the suspension height of the float chamber and the filter element can be changed; thereby, the scope of application of the device can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

The stirring rod 11 is driven by the motor 10 to rotate, so that the water and fertilizer in the mixing barrel 2 can be mixed;

[0022] A second pump body 12 is provided on one side of the mixing barrel 2, a second liquid suction pipe 13 is provided between the second pump body 12 and the mixing barrel 2, and a drip irrigation pipe 14 is fixedly provided on one side of the surface of the second pump body 12, through which water and fertilizer inside the mixing barrel 2 can be pumped out, and then drip irrigation is performed inside the field through the drip irrigation pipe 14;

[0023] The liquid inlet end of the second pump body 12 is connected to the second liquid suction pipe 13, and the liquid outlet end of the second pump body 12 is connected to the inside of the drip irrigation pipe 14.

If there is no through groove 16, the buoyancy of the float chamber 7 will basically remain unchanged no matter how the piston 8 moves.

[0026] Working principle: When using this device, the irrigation principle of this device is to pump water from the pond or river into the mixing barrel 2 through the first pump body 3, then add fertilizer into the mixing barrel 2, and then drive the stirring rod 11 to rotate through the motor 10, so that the fertilizer and water can be fully mixed, and then the water and fertilizer in the mixing barrel 2 can be pumped out by the second pump body 12, and then drip irrigation is carried out into the field through the drip irrigation pipe 14;
