[0027] See also Figure 1-Figure 5 , the present invention provides a technical solution: a new type of automatic dosing device, including a sewage tank 1;

[0028] A stirring assembly 2 is provided on the top of the sewage tank 1, and the stirring assembly 2 includes a screw frame 201 and a slide frame 202 respectively fixed on the top of both sides of the sewage tank 1, one end of the screw frame 201 is fixedly connected to the first motor 203, and the top surfaces of the screw frame 201 and the slide frame 202 are slidably fitted with lifting pads 204, and the top surfaces of the two lifting pads 204 are respectively fixedly connected with a liquid medicine delivery device 205 and a positioning cylinder 206, and the middle part of the positioning cylinder 206 is movably connected with a mounting cylinder 207, and a lifting plate 208 is fixedly connected between the two lifting pads 204; the built-in pump of the liquid medicine delivery device 205 is used to pump the internally stored liquid medicine into the through pipe 221, and finally sprayed out from the bottom of the spray pipe 222, and the lifting plate 208 is fitted and connected to the mounting cylinder 207.

[0029] Among them, the end of the mounting cylinder 207 away from the liquid medicine delivery device 205 is fixedly connected to the second motor 209 and the crank 210, the interior of the mounting cylinder 207 is rotatably connected to the rotating shaft 211, the outside of the rotating shaft 211 is fixedly connected to a plurality of first bevel gears 212, the bottom of the mounting cylinder 207 is rotatably connected to a plurality of connecting rods 213, the outside of the mounting cylinder 207 is provided with a plurality of maintenance ports 217, the outside of the maintenance ports 217 is covered with a flip plate 218; the flip plate 218 is embedded in the maintenance port 217, and the magnetic flip plate 218 is magnetically attracted by the magnetic block. 8 is flipped open, so that the staff can maintain the two bevel gears through the maintenance port 217; by holding the crank 210 and rotating it, the mounting cylinder 207 drives the second bevel gear 214 to rotate with the mounting cylinder 207 as the axis, and then the mounting cylinder 207 is pulled to make the stabilizing cross plate 215 slide into the guide frame 227. The mounting cylinder 207 and the stirring rod 216 and other parts are all moved out from just above the sewage tank 1, which is convenient for maintenance of the related parts of stirring and transmission, and avoids the situation where all parts are suspended above the sewage tank 1, which is extremely difficult to maintain.

[0030] Among them, one side of the lifting plate 208 is fixedly connected to the spray pipe 222, the top of the positioning cylinder 206 is fixedly connected to the guide frame 227, and one side of the guide frame 227 is fixedly connected to the single-sided baffle 228; when the installation cylinder 207 rotates, one end of the stabilizing cross plate 215 will first overlap with the single-sided baffle 228, and then under the pulling of the installation cylinder 207, the stabilizing cross plate 215 will slide into the guide frame 227 and maintain a stable angle of movement, which is more labor-saving.

[0031] The top end of the connecting rod 213 is fixedly connected to the second bevel gear 214, the bottom end of the connecting rod 213 is fixedly connected to the stabilizing cross plate 215, the bottom of the connecting rod 213 is rotatably connected to the same stabilizing cross plate 215, the second bevel gear 214 is meshed with the first bevel gear 212, the output end of the second motor 209 is fixedly connected to the rotating shaft 211, and the flip plate 218 is hinged to the mounting cylinder 207; by starting the second motor 209, the rotating shaft 211 drives the first bevel gear 212 to rotate, thereby causing the second bevel gear 214 to drive the connecting rod 213 to rotate, and then causing the stirring rod 216 to rotate, stirring the sewage, thereby promoting further mixing of the sprayed liquid and the sewage.

[0032] The drug liquid delivery device 205 is fixedly connected to a docking frame 219 on one side close to the mounting cylinder 207. The mounting cylinder 207 is plugged into the docking frame 219, and a bolt 220 is threadedly fixedly connected between the docking frame 219 and the mounting cylinder 207. The drug liquid delivery device 205 is composed of a built-in pump and a storage box, which can store and deliver drug liquid. When the bolt 220 fixes the mounting cylinder 207 and the docking frame 219, it can prevent the mounting cylinder 207 from moving, thereby increasing its stability during operation.

[0033] A through pipe 221 is fixedly connected to one side of the liquid medicine delivery device 205 , and the through pipe 221 is flange-connected to one end of the spraying pipe 222 .

[0034] The stabilizing cross plate 215 is overlapped with the single-sided baffle 228 and is slidingly connected to the guide frame 227. A avoidance groove 2081 for accommodating the connecting rod 213 is provided on one side of the lifting plate 208. Drainage outlets 2011 are provided at the bottom of both sides of the screw frame 201 and the sliding frame 202. Rainwater falling into the screw frame 201 and the sliding frame 202 can flow out naturally through the drainage outlets 2011. The avoidance groove 2081 can accommodate the connecting rod 213, indirectly increasing its stability.

[0035] The internal rotation connection of the sliding rod frame 202 is a threaded rod 223, the external thread connection of the threaded rod 223 is a screw sleeve 224, the internal fixed connection of the screw frame 201 is a sliding rod 225, the external sliding connection of the sliding rod 225 is a sliding sleeve 226, the two lifting pads 204 are fixedly connected to the screw sleeve 224 and the sliding sleeve 226 respectively, and the output end of the first motor 203 is fixedly connected to the threaded rod 223.

[0036] A support assembly 3 is provided on the outside of the sewage tank 1 on one side close to the positioning cylinder 206. The support assembly 3 includes a base plate 301. The top of the base plate 301 is fixedly connected to a support column 302. The top of the support column 302 is fixedly connected to a lifting block 303. The lifting block 303 is fitly connected to the bottom surface of the installation cylinder 207. When the installation cylinder 207 moves to the outside of the sewage tank 1, the lifting block 303 can lift its bottom to avoid unbalanced lifting force on the installation cylinder 207.

[0037] Working principle: Before using this new type of automatic dosing device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, the liquid medicine delivery device 205 uses its built-in pump to pump the liquid medicine in the storage tank into the through pipe 221, and then sprays it out from the bottom of the spray pipe 222 connected to the flange of the through pipe 221, so that the liquid medicine enters the sewage tank 1. At the same time, the second motor 209 is started, and the second motor 209 drives the rotating shaft 211 to rotate, and the first bevel gear 212 on the rotating shaft 211 rotates accordingly. Since the first bevel gear 212 is meshed with the second bevel gear 214, the second bevel gear 214 drives the connecting rod 213 to rotate, which in turn rotates the stirring rod 216 installed at the bottom end of the connecting rod 213, stirring the sewage and promoting further mixing of the sprayed liquid medicine and the sewage. When maintenance is needed, the handheld crank 210 is rotated to rotate the mounting cylinder 207 and the second bevel gear 214, and then the mounting cylinder 207 is pulled to allow the stabilizing cross plate 215 to slide into the guide frame 227, so that the mounting cylinder 207 and the stirring rod 216 and other parts are removed from directly above the sewage tank 1, making it convenient to maintain the stirring and transmission components.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
