Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0018] As Figures 1 to 8As shown, the present invention provides a uniformly mixed drum automatic mixing device, comprising a mixing barrel 1, wherein a section of a plate body is specifically transparent in the upper half of the mixing barrel 1, and a material trough plate 11 is fixedly connected to the bottom inner wall of the transparent plate body, and lower hoppers 12 are also fixedly connected to the two end plates of the transparent plate body, and a discharge plug is tightly clamped at the bottom of the mixing barrel 1, and a uniform mixing part 2 is provided on the mixing barrel 1, and the uniform mixing part 2 includes a forward and reverse rotating motor 21, and a connecting plate is fixedly connected to the top outer wall of the motor 21, and the bottom end of the connecting plate and the top outer wall of the mixing barrel 1 are fixedly connected. The motor 21 is fixedly connected with a screw 22 on its rotating shaft, a sleeve 23 is fixedly connected to the rod body of the screw 22, a scraper 24 is fixedly connected to the sleeve 23, the bottom end of the scraper 24 is rotatably connected to the top outer wall of the trough plate 11, a protective cover is fixedly connected to the top center of the trough plate 11, the top of the protective cover is rotatably connected to the screw 22, an oblique sleeve 25 is fixedly connected to the bottom rod body of the screw 22, a double-headed stirring rod 26 is movably sleeved on the oblique sleeve 25, and the screw 22 and the mixing barrel 1 are respectively provided with a rotating stretching structure and a piston structure.

[0019] The above scheme is adopted: the starting motor 21 drives the screw 22 and the sleeve 23 to rotate synchronously, and the rotating sleeve 23 will synchronously drive the scraper plate 24 to rotate and scrape the material on the trough plate 11, so as to facilitate the subsequent chopped peppers that are discontinuously discharged through the two discharge hoppers 12, so that they can be rotated and discharged as flatly as possible in the mixing barrel 1, and the rotating screw 22 will also synchronously drive the inclined sleeve 25 to rotate, thereby the passively rotating inclined sleeve 25 will drive the double-headed stirring rod 26 to rotate eccentrically with the trough plate 11 as the axis under the installation setting of the ball shaft 29, thereby mixing and stirring the food materials in the mixing barrel 1.

[0020] The top of the double-headed stirring rod 26 is fixedly connected to a bevel gear 27, and the bevel gear 27 is meshed with a bevel gear ring plate 28. The outer wall of the bevel gear ring plate 28 is fixedly connected to the inner wall of the protective cover. The rod body of the double-headed stirring rod 26 is fixedly connected to a ball shaft 29, and the ball shaft 29 is movably sleeved with the trough plate 11. The rotary stretching structure includes a synchronous belt 230 fixedly connected to the screw 22, and the other side of the synchronous belt 230 is also fixedly connected to a rotating rod 231. The bottom end of the rotating rod 231 is fixedly connected to a spur gear 232, and both ends of the spur gear 232 are meshed with a tooth plate 233. The rotating rod 231 is also movably sleeved with a ring head sleeve plate 234, and the ring head sleeve plate 234 is also fitted and slidably connected to the two tooth plates 233 respectively. One end plate of the ring head sleeve plate 234 is fixedly connected to the outer wall of the mixing barrel 1; An L-shaped baffle 235 is fixedly connected to the outer walls of the two tooth plates 233. An arc-shaped groove 237 is provided on the barrel of the mixing barrel 1, which can be respectively fitted and slidably connected to the two L-shaped baffles 235. Magnetic plates 236 that can be intermittently magnetically connected to the two L-shaped baffles 235 are fixedly connected to the inner walls of both ends of the mixing barrel 1.

[0021] Adopting the above scheme: the passively rotating double-headed stirring rod 26 will also drive the bevel gear 27 to mesh and rotate in the inner ring of the bevel gear ring plate 28, thereby driving the double-headed stirring rod 26 to rotate at a second level in the oblique sleeve 25, performing double-layer mechanical automatic stirring of the material, and will also synchronously drive the synchronous belt 230 to drive the rotating rod 1 231 to rotate, and the rotating rotating rod 1 231 will drive the spur gear 232 to rotate and mesh with the two tooth plates 233, so that the two tooth plates 233 can move symmetrically one after the other. The movement of the tooth plate 233 and the rotation of the rotating rod 231 will be limited and guided by the ring head sleeve 234, so that the passively moving tooth plate 233 will drive the L-shaped baffle 235 to penetrate into the mixing barrel 1 through the arc groove 237 until it contacts the magnetic plate 236 and connects with it, thereby blocking the material port at one end of the lower hopper 12. Therefore, according to the ratio of tribute vegetable and chopped pepper, whether chopped pepper needs to be supplemented can be determined, thereby achieving mixing and stirring of chopped pepper and tribute vegetable in batches, avoiding the phenomenon of local over-salty or over-light stacking.

[0022] The piston structure includes a turntable 238 threadedly connected to the screw 1 22, and a movable plate 239 is fixedly connected to the top side wall of the turntable 238, and a guide rod is slidably connected to the plate body of the movable plate 239, and the bottom end of the guide rod is fixedly connected to the top outer wall of the mixing barrel 1, and a push plate 240 is fixedly connected to the bottom outer wall of the other side of the movable plate 239. A rubber plate 241 is hinged on the plate body of the movable plate 239, and the push plate 240 and the bottom side wall of the rubber plate 241 are fitly connected. A slot 243 is opened through the rubber plate 241, and a vertical rod 242 is tightly clamped in the inner wall of the slot 243. A screw 244 is fixedly connected to the bottom end of the vertical rod 242, and a sleeve rod 245 is threadedly connected to the rod body of the screw 244. The rod body of the sleeve rod 245 is fixedly connected to the outer wall of the mixing barrel 1.

[0023] The above scheme is adopted: when the screw rod 22 rotates, it will also synchronously drive the turntable 238 and the movable plate 239 to move upward in a limited and guided manner under the limit of the guide rod, so that the rubber plate 241 hinged to the movable plate 239 will be abutted against the plate 240, so that the passively moved upward rubber plate 241 can drive the vertical rod 242 under a strong clamping friction force, and drive the vertical rod 242 and the screw rod 244 to move upward. The upward movement of the screw rod 244 will pass through the setting of the sleeve rod 245, and produce rotation while moving upward. If the amount of chopped pepper and tribute vegetable to be processed and mixed is large, and the chopped pepper and tribute vegetable need to be supplemented separately for multiple times, the rubber plate 241 can be bent up at least 90 degrees first to separate the vertical rod 242 and the card slot 243, so as to avoid structural loss of the piston structure.

[0024] A rubber stirring plate 246 is fixedly connected to the outer wall of the bottom end of screw rod 244, and a piston cylinder 2441 is rotatably connected to the rubber stirring plate 246. The top of the piston cylinder 2441 is slidingly connected to the rod body of screw rod 244, and an auxiliary hopper 247 is fixedly connected to the end of the piston cylinder 2441 near the bottom, and an inclined tube 248 is fixedly connected to the other end of the piston cylinder 2441 near the bottom. The other end of the inclined tube 248 is fixedly connected to the mixing barrel 1, and a one-way valve 249 is fixedly connected to the tube body of the inclined tube 248. A support plate frame 250 is fixedly connected to the outer wall of the bottom end of the piston cylinder 2441, and the other end plate body of the support plate frame 250 is fixedly connected to the outer wall of the mixing barrel 1.

[0025] The above scheme is adopted: the synchronously passively driven rubber stirring plate 246 will also move upward and rotate in the piston cylinder 2441, so that the auxiliary materials entering the piston cylinder 2441 through the auxiliary material hopper 247 will be briefly stirred and mixed in advance. When the motor 21 rotates in the opposite direction, the rubber stirring plate 246 that is indirectly driven to rotate downward will also generate an extrusion force in the piston cylinder 2441, thereby realizing the automatic mixing of the auxiliary material liquid from the inclined tube 248 equipped with a one-way valve 249 into the mixing barrel 1, and fusing it with the mixed chopped pepper and tribute vegetable, and realizing automatic double-layer rapid stirring and mixing processing through the continuously rotating double-headed stirring rod 26, and the auxiliary materials added later can minimize the impact on the tribute vegetable.

[0026] The working principle and use process of the present application: the preserved vegetable can be placed in the mixing machine cylinder 1 in advance, and then a small amount of chopped pepper is placed for the first time. At this time, the motor 21 can drive the screw rod 22 and the sleeve rod 1 23 to rotate synchronously. The rotating sleeve rod 1 23 can drive the scraper 24 to rotate and scrape the material groove plate 1 1, which can facilitate the pushing of the subsequent chopped pepper intermittently discharged through the two discharge hoppers 12, so that the chopped pepper can be rotated and laid as flat as possible in the mixing machine cylinder 1. The rotating screw rod 22 can also drive the inclined sleeve 25 to rotate synchronously. The passively rotating inclined sleeve 25 can drive the double-headed stirring rod 26 to rotate as an eccentric wheel with the ball shaft 29 installed and arranged as the axis of the material groove plate 1 1. Thus, the food materials in the mixing machine cylinder 1 can be mixed and stirred. At the same time, the passively rotating double-headed stirring rod 26 can also drive the bevel gear 27 to mesh and rotate in the inner ring of the bevel gear ring plate 28, so as to drive the double-headed stirring rod 26 to rotate in the inclined sleeve 25 for a second level of rotation, so as to automatically stir the materials in double layers, which can complete the mixing and stirring process more efficiently. When the screw rod 22 rotates, it can also synchronously drive the synchronous belt 230 to drive the rotating rod 231 to rotate. The rotating rod 231 can drive the spur gear 232 to rotate and the two toothed plates 233 to mesh and drive, so that the two toothed plates 233 can move symmetrically forward and backward. The movement of the two toothed plates 233 and the rotation of the rotating rod 231 can be limited and guided by the ring head sleeve plate 234. Thus, the passively moving toothed plate 233 can drive the L-shaped baffle 235 to penetrate into the mixing machine cylinder 1 through the arc-shaped groove 237 until it contacts the magnetic plate 236 connected thereto. In this way, the one end of the discharge hopper 12 can be blocked. Thus, whether the chopped pepper needs to be replenished can be determined according to the proportion of the preserved vegetable and the chopped pepper. The other end of the L-shaped baffle 235 is separated from the one end of the discharge hopper 12, so that the chopped pepper in the discharge hopper 12 can enter the material groove plate 1 1 in the mixing machine cylinder 1. At this time, the continuously rotating scraper 24 can evenly scrape and discharge the chopped pepper, so as to realize the batch mixing and stirring of the chopped pepper and the preserved vegetable, and avoid the phenomenon of local over-salting or over-dilution of the material. Meanwhile, when the screw rod 2 rotates, the rotating disc 238 and the moving plate 239 are also driven to move upward in a limited and guided manner, so that the rubber plate 241 hinged to the moving plate 239 is abutted by the abutment plate 240, and the rubber plate 241 driven to move upward can drive the vertical rod 242 and the screw rod 2 to move upward under the strong clamping friction, and the upward movement of the screw rod 2 will pass through the setting of the sleeve rod 2 245 to generate rotation while moving upward, and the rubber stirring plate 246 driven synchronously and passively will also move upward and rotate in the piston cylinder 2441, so that the auxiliary materials in the piston cylinder 2441 through the auxiliary hopper 247 will be briefly mixed and stirred first, and when the motor 21 rotates reversely, the rubber stirring plate 246 indirectly driven to rotate and move downward will also generate extrusion force in the piston cylinder 2441, so as to realize the automatic mixing of the auxiliary material liquid from the inclined pipe 248 provided with the one-way valve 249 into the mixing machine cylinder 1, and the fusion with the mixed chili and Chinese artichoke, and the automatic double-layer rapid stirring and mixing processing through the continuously rotating double-head stirring rod 26, so that the influence of the auxiliary materials added late on the Chinese artichoke can be reduced to the maximum extent.
