When this device is used, it is installed on the shore of the water area, and liquid medicine can be added to a large range of water areas.

[0004] In view of the above-mentioned prior art, the utility model inventor believes that there are the following defects:

[0005] The above-mentioned drug delivery tools can only be placed on the shore for drug delivery. However, for a large water pollution area, the drugs cannot be thrown into the middle part of the water body, which leads to uneven drug content in the water body and poor effect on cleaning pollutants in the water body. Utility Model Content

[0006] In order to solve the technical problem that a dosing device placed on the shore cannot throw liquid medicine into the middle part of the water body, thereby affecting the effect of cleaning water pollutants, the utility model provides a dosing device for water pollution control.

[0007] The utility model adopts the following technical scheme to achieve: a dosing device for water pollution control.

[0008] It includes an outer shell, both sides of which are provided with rotating grooves, and two rotating rods are provided in the rotating grooves, both ends of the two rotating rods pass through the rotating grooves and are located outside the outer shell and are provided with fan blades, and the outer shell outside the fan blades is provided with filter screens; a cleaning mechanism, the cleaning mechanism includes a cleaning rod, a rotating mechanism, and an automatic recovery mechanism, one end of the cleaning rod is provided with a rotating mechanism, and the cleaning rod can be rotated in contact with the filter screen through the rotating mechanism, thereby realizing the cleaning work of the outside of the filter screen, and the filter screen can only be rotated 180° in the bottom plate groove under the action of the automatic recovery mechanism; a feeding mechanism, the feeding mechanism includes a sealing plate and an elastic unit, and the sealing plate can be automatically closed after feeding under the drive of the elastic unit.

[0009] Through the above technical solution, the filter can be cleaned under the action of the cleaning mechanism, so that the fan blades can rotate stably, and the debris in the water will not affect the rotation of the fan blades. Under the action of the feeding mechanism, the medicine solution and water can enter the mixing barrel more conveniently, avoiding the situation in the traditional device where the lid needs to be opened for feeding and then closed.

[0010] As a further improvement of the above scheme, a motor is provided at the bottom of the inner cavity of the shell, and a rotating rod 1 is provided at the top of the motor through a coupling, a bevel gear 1 is provided at the top of the rotating rod 1, the outside of the bevel gear 1 is meshedly connected with a bevel gear 2, and the middle part of the bevel gear 2 is provided on the rotating rod 2, bevel gear 5 is symmetrically provided on the outside of the rotating rod 2, and the bevel gear 5 is located in the inner cavity of the shell, the outside of the bevel gear 5 is meshedly connected with a bevel gear 4, and a rotating rod 3 is provided at the top of the bevel gear 4, and the top of the rotating rod 3 is connected to the top in the inner cavity of the shell through a bearing.

[0011] Through the above technical solution, by providing a waterproof layer on the motor and a waterproof cover on the outside of the motor, the waterproof property of the motor can be further improved, so that the shell can move for a long time in the water, and by rotating the rotating rod 2, the two fan blades are driven to rotate, so that the shell can move stably in the water, ensuring the uniformity of the spraying of the liquid medicine.

[0012] As a further improvement of the above scheme, the rotating mechanism includes a limit groove, a round rod, a gear, a cleaning rod, and a half gear.

[0013] Through the above technical solution, when the rotating rod three rotates, the two half gears also rotate. Because the half gears are half gears, when the half gears and the gears form a meshing connection, they can drive the round rod to rotate. When the gears and the half gears are in contact and meshing connection, the spring recovers its deformation, causing the cleaning rod to return to its initial position, thereby reciprocating to clean the filter.

[0015] Through the above technical scheme, when the round rod is rotated by the gear under the action of spring 1, the cleaning rod can be driven back to its original position under the action of the deformation of spring 1. The cleaning rod can rotate around the groove of the filter seat bottom plate more stably in this reciprocating manner, thereby achieving a better cleaning effect on the filter. The cleaning rod is more stable when rotating in conjunction with the rotation of the bottom plate on the bottom plate groove.

[0017] Through the above technical solution, by providing a sealing gasket inside the movable groove and squeezing the sealing gasket outside the rotating rod 4, the liquid in the mixing barrel will not flow into the inner cavity of the shell, further ensuring the sealing of the device.

[0018] As a further improvement of the above scheme, the elastic mechanism includes a feed barrel, a sealing plate, a hinged rod, a sliding sleeve, a sliding groove, a sliding rod and a second spring. The feed barrel is fixed on the top of the mixing barrel, one end of the sealing plate is hinged to one end of the feed barrel, one end of the hinged rod is hinged to the bottom of the sealing plate, and the other end of the hinged rod is hinged to the sliding sleeve. The sliding sleeve slides on the sliding rod, and both ends of the sliding rod are arranged inside the sliding groove. The sliding groove is opened on one side of the feed barrel near the hinge of the sealing plate. The second spring is respectively welded to the inside of the sliding groove and on the sliding sleeve, and the middle part of the second spring is wrapped around the sliding rod.

[0019] Through the above technical solution, by sliding the sliding sleeve on the sliding rod and stretching the spring 2 at the same time, the hinged action of the hinged rod can make one side of the sealing plate move up and down more stably, avoiding the cumbersome steps of opening and then closing when adding medicine, and a deformable sealing gasket is provided at the bottom of the sealing plate to contact with the top of the feed barrel, which also helps to ensure the sealing.
