[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: an agricultural chemical mixing device, including an outer shell 1, a feeding hopper 2, a discharge pipe 3, a motor 4, a rotating cylinder 5, a stirring rod 6, a driving wheel 7, a driven wheel 8, a scraping rod 9, a feeding cylinder 10, and a connecting block 11.

[0027] Inside the housing 1, a feeding structure is provided. The feeding structure is equipped with a feeding cylinder 10 and a connecting block 11 to achieve uniform feeding of raw materials. The feeding structure includes a feeding cylinder 10, which is a cylindrical structure with an open lower surface. Inside the feeding cylinder 10, a connecting block 11 is provided. The connecting block 11 is a frustum structure, and connecting rods are arranged on the outer surface of the connecting block 11 and fixedly connected to the inner wall of the feeding cylinder 10. The feeding cylinder 10 and the connecting block 11 together form a hollow cylindrical structure with an annular opening on the lower surface. The upper surface of the feeding cylinder 10 is rotatably connected to the lower end of the feeding hopper 2, and the lower end of the feeding hopper 2 penetrates and inserts into the inside of the feeding cylinder 10. The connecting block 11 is fixedly connected to the outer surface of the rotating cylinder 5;

[0028] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, when using this device, start the motor 4. The motor 4 drives the rotating cylinder 5 to rotate. The rotating rotating cylinder 5 drives the connecting block 11 to rotate. The rotating connecting block 11 drives the feeding cylinder 10 to rotate. Put the pesticide agent to be mixed into the feeding hopper 2. The pesticide agent enters the feeding cylinder 10 from the feeding hopper 2 and falls into the device along the frustum-shaped connecting block 11. Since the connecting block 11 always rotates with the rotating cylinder 5, under the action of centrifugal force, the pesticide agent evenly falls into the inside of the housing 1. Put water into the same feeding hopper 2. The water flow falls into the device under the same acting force, and the water flow washes the residual pesticide agent on the surface of the connecting block 11 to avoid pesticide residue.

[0029] The housing 1 is a hollow cylindrical structure, and a frustum-shaped convex block is provided at the center of the bottom surface inside the housing 1. The bottom surface inside the housing 1 is a circular ring-shaped groove, and the inner wall of the groove inside the housing 1 is inclined. The lower surface of the housing 1 is fixedly installed with a motor 4. The output end of the motor 4 penetrates the surface of the housing 1 and is connected to a rotating cylinder 5. The rotating cylinder 5 penetrates the frustum-shaped convex block inside the housing 1. A scraping rod 9 is fixedly installed on the outer surface of the rotating cylinder 5. Two scraping rods 9 are symmetrically arranged. The scraping rod 9 is an inverted trapezoid structure, and the scraping rod 9 is in contact with the bottom surface of the inner wall of the housing 1;

[0030] As Figure 1 and Figure 3 shown, when the pesticide agent and water fall, under the action of the inclined inner wall of the groove, the pesticide agent will not accumulate at the gaps of the housing 1, thus avoiding dead corners during the stirring process of pesticide mixing. During the stirring and mixing process, the scraping rod 9 always rotates with the rotating cylinder 5. The rotating scraping rod 9 generates a force on the inner wall of the groove of the housing 1, further preventing the accumulation of pesticides during the pesticide mixing process.

[0031] The outer shell 1 is a hollow cylindrical structure. A feed hopper 2 is provided through the upper surface of the outer shell 1, and a discharge pipe 3 is provided through the lower surface of the outer shell 1. A valve is provided inside the discharge pipe 3 to control the opening and closing. At the center of the bottom surface inside the outer shell 1, a frustum-shaped convex block is provided. The bottom surface inside the outer shell 1 is an annular groove, and the inner wall of the groove inside the outer shell 1 is inclined. A stirring structure is provided inside the outer shell 1. The stirring structure is driven by the same motor 4 to make two symmetric stirring rods 6 rotate out of sync. The stirring structure includes a motor 4. The motor 4 is fixedly installed on the lower surface of the outer shell 1. The output end of the motor 4 penetrates the surface of the outer shell 1 and is connected to a rotating cylinder 5. The rotating cylinder 5 penetrates the frustum-shaped convex block inside the outer shell 1. Stirring rods 6 are respectively provided on both sides of the rotating cylinder 5. The two stirring rods 6 are symmetrically arranged, and the upper end of the stirring rod 6 is rotatably connected to a bracket. The other end of the bracket connected to the stirring rod 6 is fixedly installed on the inner wall of the outer shell 1. A driving wheel 7 is fixedly installed on the outer surface of the rotating cylinder 5. The driving wheel 7 is a hollow toothed gear structure with missing teeth. A driven wheel 8 is fixedly installed on the outer surface of the rotating shaft of the stirring rod 6. The driven wheel 8 is a hollow gear structure. The driving wheel 7 meshes with the driven wheels 8 on both sides respectively;

[0032] As Figure 1 and Figure 6 shown, after the motor 4 is started, the motor 4 drives the rotating cylinder 5 to rotate. The rotation of the rotating cylinder 5 drives the driving wheel 7 to rotate. When the driving wheel 7 rotates, when the toothed part on the surface meshes with the driven wheel 8, it drives the driven wheel 8 on one side to rotate. The rotating driven wheel 8 drives the stirring rod 6 to rotate. When the missing-tooth part of the driving wheel 7 contacts the driven wheel 8 on this side, the driven wheel 8 on this side stops rotating. When the driving wheel 7 continues to rotate, it continuously drives the driven wheels 8 on both sides to rotate out of sync, so that the stirring rods 6 on both sides rotate out of sync to fully mix the pesticide and water. After the mixing is completed, the valve inside the discharge pipe 3 is opened to discharge the mixed pesticide agent from the device.

[0033] Working principle: When using this agricultural agent mixing device, start the motor 4. The motor 4 drives the rotating cylinder 5 to rotate continuously. During the rotation of the rotating cylinder 5, it drives the driving wheel 7 and the connecting block 11 to rotate. The pesticide agent and water are put in from the feed hopper 2 and enter the feed cylinder 10, and evenly fall into the device along the surface of the rotating connecting block 11. The annular groove inside the outer shell 1 can prevent the pesticide agent from accumulating at the edge of the outer shell 1, thus causing a stirring dead angle. The rotating driving wheel 7 continuously drives the driven wheels 8 on both sides to rotate out of sync, driving the stirring rods 6 to rotate out of sync to fully mix the pesticide agent, increasing the overall practicality.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
