[0021] The present invention will be further described below with reference to embodiments.

[0022] Example 1, please refer to Figures 1-12 A premixed feed mixing device with quantitative feeding function, comprising a tank 1; A tank cover 2 is fixedly connected to the top of the tank body 1, and a discharge pipe 6 is fixedly connected to the bottom of the tank body 1; A gate valve is fixedly installed on the discharge pipe 6; The top of the can lid 2 is connected to a mixing component 4 for driving the material upward and mixing it. The lower end of the mixing component 4 is fixedly connected to the bottom of the can body 1. The top of the can lid 2 is connected to an adjustable dispensing assembly 3 for adding additives; The adjustable liquid addition assembly 3 includes a cam 31, a separation assembly, a follow-up quantitative dispensing assembly, and a self-sealing spray assembly. The cam 31 is fixedly connected to the drive end of the mixing assembly 4. The separation assembly and the follow-up quantitative dispensing assembly are fixedly installed on the top of the tank cover 2. When the additive is added, the separation assembly and the follow-up quantitative dispensing assembly do not contact each other, and the follow-up quantitative dispensing assembly is in close contact with the cam 31. When no additive is added, the separation assembly and the follow-up quantitative dispensing assembly are in close contact, and the follow-up quantitative dispensing assembly is not in contact with the cam 31. The follow-up quantitative dispensing assembly is in communication with the self-sealing spray assembly and is fixedly connected. The self-sealing spray assembly is fixedly installed on the top of the tank cover 2, and the spray end of the self-sealing spray assembly faces the discharge end of the mixing assembly 4. The top of the can lid 2 is also fixedly connected to a multi-component synchronous feeding component 5 for adding multiple groups of powders in equal proportions.

[0023] The multi-component synchronous feeding component 5 adds multiple powders to the tank 1 in equal proportions, enabling simultaneous addition of multiple powders in equal proportions, which helps with precise and rapid feeding. The separation component of the adjustable liquid addition component 3 drives the follow-up quantitative dispensing component to separate from the cam 31. The mixing component 4 drives the multiple powders to perform preliminary mixing. After preliminary mixing, the separation component separates from the follow-up quantitative dispensing component, and the follow-up quantitative dispensing component contacts the cam 31. The mixing component 4 drives the cam 31 to rotate, and the cam 31 drives the follow-up quantitative dispensing component to quantitatively extract the additives into the self-sealing spraying component. The additives are sprayed outward through the self-sealing spraying component to the outward-turning pre-mixed materials, which helps the additives and powders to mix quickly and thoroughly, and facilitates rapid and uniform mixing of premixed feed.

[0024] Please see Figures 1-8 The mixing component 4 includes a first support frame 41, a first motor 42, a third connecting seat 43, a conical guide plate 44, a straight cylinder 45, a first auger 46, a second auger 47, and a connecting shaft 49. The first support frame 41 is fixedly installed on the top of the can cover 2. The first motor 42 is fixedly installed on the top of the first support frame 41.

The connecting shaft 49 passes through the can cover 2 and is fixedly connected to the top of the first auger 46. The second auger 47 is fixedly installed at the bottom of the first auger 46 and is located inside the discharge pipe 6. Multiple sets of third connecting seats 43 are fixedly installed at the bottom of the can cover 2. The bottom of the multiple sets of third connecting seats 43 is fixedly connected to the conical guide plate 44. The top of the conical guide plate 44 is fixedly connected to the straight cylinder 45, and the first auger 46 is located inside the straight cylinder 45. The outer wall of the first auger 46 is slidably connected to the inner wall of the straight cylinder 45.

[0025] A scraper 48 is fixedly connected to the outer wall of the lower end of the first auger 46, and the scraper 48 is slidably connected to the inner wall of the tank 1.

[0026] The connecting shaft 49 is rotatably connected to the can lid 2 via a bearing.

[0027] The connecting shaft 49 is fixedly installed in the mounting hole of the cam 31; The drive end of the first motor 42, the connecting shaft 49, the straight cylinder 45, the first auger 46 and the second auger 47 are coaxially arranged; The multi-component synchronous feeding component 5 adds multiple powder components to the tank 1 in equal proportions, enabling simultaneous addition of multiple powder components in equal proportions, which helps with precise and rapid feeding. The separation component of the adjustable liquid addition component 3 drives the follow-up quantitative dispensing component to separate from the cam 31. The first motor 42 of the mixing component 4 drives the connecting shaft 49 to rotate clockwise. The connecting shaft 49 drives the first auger 46 to rotate. The first auger 46 drives the second auger 47 to rotate. The second auger 47 flips the material in the discharge pipe 6 upwards to prevent the material in the discharge pipe 6 from not contacting the additives and to ensure that the material in the discharge pipe 6 participates in the mixing. The first auger 46 and the straight... The cylinder 45, in conjunction with the material inside the tank 1, is turned upward through the straight cylinder 45 and then evenly distributed to the upper end of the tank 1 through the conical guide plate 44, achieving preliminary mixing of multiple powders. After preliminary mixing, the separation component separates from the follow-up quantitative dispensing component. The follow-up quantitative dispensing component contacts the cam 31, and the connecting shaft 49 drives the cam 31 to rotate. The cam 31 drives the follow-up quantitative dispensing component to quantitatively extract the additive into the self-sealing spraying component. The additive is sprayed outward through the self-sealing spraying component to the material that is turned outward, which helps the additive and powder to mix quickly and thoroughly, and facilitates the rapid and uniform mixing of premixed feed.

[0028] The first auger 46 drives the scraper 48 to rotate, and the scraper 48 scrapes the material on the inner wall of the tank 1 to prevent the material from sticking to the inner wall of the tank 1.

[0029] After mixing is completed, the gate valve on the discharge pipe 6 is opened, the first motor 42 drives the connecting shaft 49 to rotate counterclockwise, the connecting shaft 49 drives the first auger 46 to rotate, the first auger 46 drives the second auger 47 to rotate, and both the first auger 46 and the second auger 47 push the material downward, which helps the mixed feed to be discharged quickly.

[0030] Please see Figures 1-9 , Figures 11-12The follow-up metering dispensing assembly includes a first one-way valve 33, a first pipe 34, a cylinder 35, a second one-way valve 36, a second pipe 37, a roller 38, a first spring 313, a mounting bracket 314, a second connecting seat 315, a second sliding rod 321, and a second piston 322. The second connecting seat 315 is fixedly installed on the top of the tank cover 2. The cylinder 35 is fixedly installed in the mounting hole opened in the second connecting seat 315. The outer wall of the second piston 322 is slidably connected to the inner wall of the cylinder 35. The end of the second piston 322 near the connecting shaft 49 is fixedly connected to the second sliding rod 321. The end of the second sliding rod 321 near the connecting shaft 49 is fixedly connected to the mounting bracket 314. The roller 38, which cooperates with the cam 31, is located near the end of the connecting shaft 49. Rotatably connected to the mounting bracket 314, the first spring 313 is located between the mounting bracket 314 and the cylinder 35, the first spring 313 is sleeved on the outside of the second slide rod 321, the second pipe 37 and the first pipe 34 are fixedly installed at the end of the cylinder 35 away from the connecting shaft 49, the second one-way valve 36 is fixedly installed on the second pipe 37, and the first one-way valve 33 is fixedly installed on the first pipe 34. When the second piston 322 moves toward the connecting shaft 49, the second one-way valve 36 opens and the first one-way valve 33 closes. When the second piston 322 moves away from the connecting shaft 49, the second one-way valve 36 closes and the first one-way valve 33 opens. The first pipe 34 is fixedly connected to the self-sealing liquid spraying assembly, and the lower end of the mounting bracket 314 is connected to the separation assembly.

[0031] The second pipe 37 is fixedly connected to the auxiliary agent storage device.

[0032] The second slide rod 321 is in close contact with the sliding hole opened in the cylinder 35 for sliding connection.

[0033] The separation assembly includes a cylinder 32, a push plate 311, and a guide rail assembly 312. The cylinder 32 and the guide rail assembly 312 are fixedly mounted on the top of the can cover 2. The slider of the guide rail assembly 312 is fixedly mounted on the push plate 311. The push plate 311 is fixedly connected to the drive end of the cylinder 32. The push plate 311 is located between the cam 31 and the mounting bracket 314.

[0034] When no additives are added, the push plate 311 is in close contact with the mounting bracket 314; when additives are added, the push plate 311 is not in contact with the mounting bracket 314. The self-sealing spray assembly includes an annular pipe 39, multiple sets of first connecting seats 310, and multiple sets of sealing spray assemblies. The multiple sets of first connecting seats 310 are fixedly installed on the top of the tank cover 2. The multiple sets of first connecting seats 310 are fixedly connected to the annular pipe 39. The annular pipe 39 is connected to the first pipe 34. The multiple sets of sealing spray assemblies are fixedly installed on the annular pipe 39 along the circumference, and the spraying end of the sealing spray assembly faces outward and downward.

[0035] The sealing-type liquid spray assembly includes a first piston 316, a second spring 317, a first slide rod 318, an outer cylinder 319, a conical rod 320, and a conical nozzle 323. The outer cylinder 319 and the conical nozzle 323 are fixedly installed at the upper and lower ends of the annular tube 39, and are coaxially arranged. One end of the conical rod 320 is in contact with the inner wall of the conical nozzle 323, and the other end of the conical rod 320 is fixedly connected to the first piston 316. The outer wall of the first piston 316 is in contact with the outer... The inner wall of the cylinder 319 is in close sliding connection. The second spring 317 is located between the end of the first piston 316 away from the conical rod 320 and the inner end of the outer cylinder 319 away from the annular tube 39. The second spring 317 is sleeved on the outside of the first slide rod 318. The end of the first slide rod 318 away from the conical nozzle 323 is in close sliding connection with the end of the outer cylinder 319 away from the conical nozzle 323. When the conical rod 320 is in close contact with the conical nozzle 323, the second spring 317 is in a compressed state. The multi-component synchronous feeding component 5 adds multiple powders to the tank 1 in equal proportions, enabling simultaneous addition of multiple powders in equal proportions, which helps with accurate and rapid feeding. The cylinder 32 of the separation component of the adjustable liquid addition component 3 drives the push plate 311 to move along the guide rail component 312. The push plate 311 moves to contact the mounting frame 314, pushing the mounting frame 314 to move away from the connecting shaft 49. The mounting frame 314 drives the roller 38 to separate from the cam 31. The follow-up quantitative dispensing component does not work and no additives are added. At this time, the driving force requirement of the first motor 42 can be reduced, which can reduce energy consumption.

[0036] After initial mixing, the cylinder 32 of the separation component drives the pusher plate 311 to move along the guide rail assembly 312 and the connecting shaft 49. The pusher plate 311 separates from the mounting bracket 314 of the follow-up metering dispensing component. The first spring 313 of the follow-up metering dispensing component drives the mounting bracket 314 to move towards the connecting shaft 49. The mounting bracket 314 drives the roller 38 to move until it contacts the cam 31. The cam 31 drives the roller 38 to rotate. When the roller 38 contacts the protruding part from the base circle surface of the cam 31, the cam 31 pushes the roller 38 to move away from the connecting shaft 49. The roller 38 drives the second slide rod 321 to move away from the connecting shaft 49. The second slide rod 321 drives the second piston 322 to move away from the connecting shaft 49. The first one-way valve 33 opens and the second one-way valve 36 closes. The additive in the cylinder 35 enters the first pipe 34. The roller 38... When the protruding part of the cam 31 contacts the base circular surface, the mounting bracket 314 drives the second slide rod 321 to move towards the connecting shaft 49. The second slide rod 321 drives the second piston 322 to move towards the connecting shaft 49, creating a negative pressure inside the cylinder 35. The additive enters the cylinder 35 through the second pipe 37. The amount of additive added when the cam 31 rotates once is equal to the volume inside the cylinder 35. The additive in the first pipe 34 enters the annular pipe 39 of the self-sealing spray assembly. The high-pressure additive in the annular pipe 39 drives the first piston 316 to move away from the conical spray nozzle 323. The first piston 316 drives the conical rod 320 to move away from the conical spray nozzle 323, opening the conical spray nozzle 323. The high-pressure additive is sprayed through the conical spray nozzle 323 onto the outwardly tumbling pre-mixed material, which helps the additive and powder to mix quickly and thoroughly, facilitating the rapid and uniform mixing of premixed feed.

[0037] After the pressure of the additive in the annular tube 39 decreases, the second spring 317 pushes the first piston 316 to move toward the conical nozzle 323. The first piston 316 drives the conical rod 320 to move toward the conical nozzle 323. The conical rod 320 blocks the conical nozzle 323, preventing powder from entering the conical nozzle 323 when no liquid is being sprayed, thus ensuring the liquid spraying performance of the conical nozzle 323.

[0038] Preferably, in order to ensure continuous liquid spraying from the conical nozzle 323, a set of follow-up metering dispensing components and a set of separation components are added to the top of the tank cover 2. The two sets of follow-up metering dispensing components are symmetrically arranged on both sides of the connecting shaft 49, and the two sets of separation components are symmetrically arranged on both sides of the connecting shaft 49. Without the addition of additives, the two sets of separation components are in contact with the two sets of follow-up metering components respectively, and neither set of follow-up metering components is in contact with the cam 31. When adding additives, the two sets of separation components separate from the two sets of follow-up metering components respectively. Both sets of follow-up metering components are in contact with the cam 31. When one set of follow-up metering components is in contact with the base circle surface of the cam 31, the other set of follow-up metering components is in contact with the protruding part of the cam 31. This allows the two sets of follow-up metering components to operate alternately. When additives are added to the cylinder 35 of one set of follow-up metering components, additives are discharged from the cylinder 35 of the other set of follow-up metering components. When additives are discharged from the cylinder 35 of one set of follow-up metering components, additives are added to the cylinder 35 of the other set of follow-up metering components. This allows for continuous addition of additives to the self-sealing spraying component.
