[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a water conservancy irrigation device, including a long water pumping tube 1, a filter head 2 is rotatably installed at the rear end of the long water pumping tube 1, a scraper block 104 is fixedly connected to the long water pumping tube 1 and near the rear end edge, the scraper block 104 fits the surface of the filter head 2, a transfer seat 3 is arranged below the long water pumping tube 1, support wheels 301 are rotatably installed on both sides of the transfer seat 3 through an axis, a drag head 105 is fixedly connected to the long water pumping tube 1 near the front end edge, a connecting shaft 4 is rotatably installed in the long water pumping tube 1, and the connecting shaft 4 cooperates with the filter head 2 through a relay structure.

[0023] In this embodiment, the transfer seat 3 can support the long water pumping pipe 1, and the support wheel 301 enables the entire device to be dragged on the ground, so that the towing head 105 can be used to connect with agricultural machinery such as tractors, and the towing device can be directly moved by the agricultural machinery without moving the towing device up and down. Secondly, the connecting shaft 4 is connected to the filter head 2 through a relay device. The rotation of the connecting shaft 4 can drive the filter head 2 to rotate, and the scraper block 104 fits the outer wall of the filter head 2, so that the rotation of the filter head 2 can scrape off impurities adsorbed on the surface of the filter head 2, thereby preventing impurities from accumulating and clogging the filter head 2 and affecting water intake.

[0024] Among them, in order to achieve the purpose of fixing the transfer seat 3 and the long water pumping tube 1, the present device is implemented by adopting the following technical scheme: dovetail sliders 101 are fixedly connected on both sides of the long water pumping tube 1, and two fixing holes 102 are provided on the side of the dovetail slider 101 on one side, one fixing hole 102 is located in the middle of the dovetail slider 101, and the other fixing hole 102 is close to the front end of the dovetail slider 101, and a drain outlet 103 is fixedly installed on the long water pumping tube 1, and symmetrical limiting blocks 302 are fixedly connected to the transfer seat 3, and dovetail grooves 303 are provided on the opposite surfaces of the two limiting blocks 302, and the dovetail grooves 303 are slidably matched with the dovetail slider 101, and a threaded through hole 304 is provided in the limiting block 302 on one side, and a fixing bolt 305 is installed with a thread in the threaded through hole 304, and the fixing bolt 305 cooperates with the fixing hole 102.

[0025] By slidingly cooperating with the dovetail slider 101 and the dovetail groove 303, the long pumping tube 1 and the transfer seat 3 are slidably connected together. When the device is towed, the transfer seat 3 can be moved to the center of the long pumping tube 1, and the fixing bolt 305 can be rotated so that its end is stuck in the fixing hole 102, so that the long pumping tube 1 and the transfer seat 3 are relatively fixed together for easy towing. When pumping irrigation operations are required, the transfer seat 3 needs to be moved to the front end of the long pumping tube 1, and the fixing bolt 305 needs to be screwed into the fixing hole 102 near the front end to avoid affecting the insertion of the end of the long pumping tube 1 into the water channel.

[0026] Among them, in order to achieve the purpose of driving the filter head 2 to rotate, the present device is implemented by the following technical solutions: the relay structure includes a support seat 5 and a relay gear 501, the relay gear 501 is rotatably connected to the support seat 5 through an axis, the support seat 5 is fixedly connected to the inner wall of the long water pumping pipe 1, the support seat 5 is rotatably connected to the connecting shaft 4, the inner wall of the front end of the filter head 2 is fixedly connected with an internal tooth 201, the relay gear 501 and the internal tooth 201 cooperate with each other, the rear end of the connecting shaft 4 is fixedly connected with an active tooth 403, the active tooth 403 and the relay gear 501 cooperate with each other, a belt pulley 401 is fixedly connected to the connecting shaft 4, and a screw dragon 402 is fixedly connected to the front end of the connecting shaft 4.

[0027] The auger 402 can be connected to the power device through a belt. The rotation of the auger 402 can drive the connecting shaft 4 to rotate. The rotation of the connecting shaft 4 will drive the belt pulley 401 to rotate, thereby extracting river water. At the same time, the rotation of the connecting shaft 4 will also drive the active tooth 403 to rotate. The rotation of the active tooth 403 will drive the relay gear 501 to rotate. The rotation of the relay gear 501 will drive the filter head 2 to rotate.

[0028] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, and the auger 402 is connected to the power device by a belt, so that driving the auger 402 to rotate can drive the connecting shaft 4 to rotate, and the rotation of the connecting shaft 4 can simultaneously drive the belt pulley 401 and the filter head 2 to rotate. The rotation of the belt pulley 401 can draw river water into the drain outlet 103, and the drain outlet 103 is connected to a pipeline for irrigation. The rotation of the filter head 2 cooperates with the scraper block 104 to scrape off the impurities adsorbed by the filter head 2, thereby preventing the impurities from gradually accumulating and affecting the suction efficiency.
