[0001] The utility model relates to the technical field of agricultural equipment, in particular to an automatic feeding device for powdered pesticides. Background Art

[0002] Pesticides refer to chemical agents used in agriculture to prevent and control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry and animal husbandry production, environmental and household hygiene pest control and epidemic prevention, industrial product mildew and moth prevention, etc. Before spraying pesticides, the ratio of water to powdered pesticides needs to be adjusted, and then stirred to mix the water and pesticides. The prepared mixed pesticide diluent is then placed in a specific container and sprayed on the plants.

[0003] Reference is made to Chinese patent authorization announcement number CN 218924592 U, which discloses an automatic feeding device for powder pesticides. The automatic feeding device for powder pesticides is mainly composed of: a bracket, a tank body, a controller, a stirring mechanism, a medicine box and a water inlet pipe. The tank body is arranged on the bracket, the controller is arranged on the outer wall of the tank body, the stirring mechanism is arranged inside the tank body, and the medicine box and the water inlet pipe are both arranged at the top of the tank body; the automatic feeding device for powder pesticides of the utility model has a simple structure and is easy to operate. It can automatically perform accurate feeding and water addition and stirring by weighing, automatically complete the preparation of pesticides, and can prepare a large amount of liquid medicine at one time according to needs, thereby improving work efficiency, reducing the workload of workers, and greatly reducing the number of times that manual labor contacts powder medicines, thereby avoiding harm to the health of workers caused by pesticides;

[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies. When the powder is added into the tank, the powder will float to various positions on the inner wall of the tank. Since the tank is generally not filled with water, the powder adhering to the upper end of the inner wall of the tank is difficult to contact with water, which will cause insufficient mixing of the powder and water and waste of powder. When the powder and water are stirred, generally only one-way stirring is performed by the stirring blade. Since the stirring direction of the stirring blade is single, the stirring efficiency of the powder and water is limited. Utility Model Content

DETAILED DESCRIPTION

[0024] A powder pesticide automatic feeding device:

[0025] like Figure 1 , 2 As shown, in this embodiment, it includes a frame 1 and a feed tank 2, the feed tank 2 is rotatably connected to the inner side of the frame 1, a powder metering cylinder 3 is provided above the feed tank 2, the upper end of the powder metering cylinder 3 is connected with a feed valve 4, a metering valve 5 is connected between the powder metering cylinder 3 and the feed valve 4, a discharge valve 11 is connected to the lower end of the feed tank 2, a water inlet valve 21 is connected to the upper end of the feed tank 2, and a glass observation window 20 is installed at the front end of the feed tank 2;

[0026] When liquid pesticide is produced by the feeding device, water is loaded into the feeding tank 2 through the water inlet valve 21, and the water level in the feeding tank 2 is checked in conjunction with the glass observation window 20 until the water level reaches the standard, and then the water inlet valve 21 is closed, and then the feeding valve 4 is opened to add the powder into the powder metering cylinder 3, and then the corresponding amount of powder is measured through the powder metering cylinder 3 until the amount of powder reaches the standard, and then the feeding valve 4 is closed, and then the metering valve 5 is opened to add the powder in the medicine metering cylinder 3 into the feeding tank 2. After the addition is completed, the metering valve 5 is closed to mix the water and the powder.

[0027] like Figure 2 As shown, in this embodiment, a flip driving assembly is provided on the right side of the feed tank 2, and the flip driving assembly includes a flip motor 7, a driving gear 8, a bearing shaft 6 and a driven gear 9. The flip motor 7 is fixed to the right side of the frame 1, and the driving gear 8 is connected to the power end of the flip motor 7. The bearing shaft 6 is rotatably connected to the right side of the frame 1. The right side of the feed tank 2 is fixed to the left end of the bearing shaft 6, and the driven gear 9 is fixedly sleeved on the periphery of the bearing shaft 6, and the driving gear 8 is meshed with the driven gear 9;

[0028] When medicine powder and water are added into the feed tank 2, and the medicine powder on the inner wall of the feed tank 2 needs to be fully mixed with the water, then the flip motor 7 is started to drive the driving gear 8, the driven gear 9 and the bearing shaft 6 to rotate reciprocatingly. At the same time, the bearing shaft 6 will drive the feed tank 2 to flip 360 degrees reciprocatingly, which is conducive to the water in the feed tank 2 to fully contact with the inner wall of the feed tank 2, thereby facilitating the medicine powder on the inner wall of the feed tank 2 to fully contact and mix with the water, effectively reducing the waste of medicine powder.

[0029] like Figure 2-4 As shown, in this embodiment, a stirring motor 12 is fixed at the lower end of the feed tank 2, and a driving shaft 13 is connected to the power end of the stirring motor 12. The driving shaft 13 rotates upward and penetrates into the feed tank 2. A shaft tube 10 fixed to the upper end of the driving shaft 13 is provided in the feed tank 2. A fixed shaft 16 is fixed at the top of the feed tank 2. The fixed shaft 16 rotates from top to bottom and penetrates into the shaft tube 10. First stirring blades 14 are provided on both sides of the shaft tube 10. A plurality of second stirring blades 15 are fixed on the upper and lower ends of the first stirring blade 14. The left and right adjacent two stirring blades 15 are provided with a plurality of second stirring blades 15. A synchronous rotation drive assembly is provided between the first stirring blades 14, and the synchronous rotation drive assembly includes a main bevel gear 17, a synchronous shaft 19 and a secondary bevel gear 18. The main bevel gear 17 is fixedly sleeved on the outer periphery of the fixed shaft 16. Two synchronous shafts 19 are provided and fixed one by one to the inner side of the adjacent first stirring blades 14. The synchronous shafts 19 rotate inwardly and penetrate into the shaft tube 10. Two secondary bevel gears 18 are provided and fixed one by one to the inner ends of the adjacent fixed shafts 16. The secondary bevel gears 18 are meshed with the adjacent main bevel gears 17;

[0030] When the feed tank 2 is in the process of reciprocating flipping, the driving shaft 13 and the shaft tube 10 are driven to rotate together through the operation of the stirring motor 12, and the shaft tube 10 will drive the synchronous shaft 19, the first stirring blade 14 and the second stirring blade 15 to rotate left and right continuously. At this time, the rotation of the shaft tube 10 drives the first stirring blade 14 and the second stirring blade 15 to stir and mix, which is conducive to quickly and evenly mixing the powder and water together. Since the shaft tube 10 rotates along the outer periphery of the fixed shaft 16, the fixed shaft 16 is under the premise of being stationary, and the shaft tube 10 drives the synchronous shaft 19 and the secondary bevel gear 18 to rotate, When the main bevel gear 17 is meshed with the sub-bevel gear 18, the main bevel gear 17 will drive the sub-bevel gear 18 to rotate, so the sub-bevel gear 18 will drive the synchronous shaft 19, the first stirring blade 14 and the second stirring blade 15 to rotate back and forth. In summary, the first stirring blade 14 and the second stirring blade 15 can both stir in at least two directions, and realize automatic stirring of the production of liquid pesticides, thereby facilitating a faster and more effective improvement in the stirring and mixing efficiency of the powder and water. When the production of the liquid pesticide is completed, the discharge valve 11 is opened to discharge the liquid pesticide to effectively ensure the efficiency of the pesticide feeding production.
