Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a biaxial mixer. Background Technology

[0002] Mixing is a crucial step in the processing of pig feed, which requires the use of a twin-shaft mixer. The twin-shaft mixer uses blades on two rotating shafts to generate mechanical force, causing the material to undergo convection, shearing, and diffusion movements within the machine to achieve uniform mixing. Specifically, when the blades rotate, they propel the material to flow rapidly along the axial and radial directions, forming a large-scale convection that allows different components of the material to exchange positions quickly. At the same time, relative motion occurs between the blades and the material, as well as between material layers, generating shearing force that breaks up material agglomerates and refines particles. In addition, due to local velocity differences in the material, microscopic penetration occurs between particles, achieving a finer mixing.

[0003] However, when traditional twin-shaft mixers discharge, the feed is easily left in corners and gaps because the bottom of the casing is closed or the opening is small, resulting in incomplete discharge. This not only wastes feed resources but may also cause cross-contamination, affecting the quality of the next batch of feed. At the same time, traditional mixers are mostly fixed structures, making cleaning work more cumbersome and increasing labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a biaxial mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] Please see Figure 1-5In this embodiment of the present invention, a dual-shaft mixer includes a dual-shaft mixer body 100, which includes a mixing chamber 110, a stirring shaft 120, a feeding box 130, an electric telescopic rod 140, a side frame 150, a drive motor 160, and an electric telescopic rod 180. The mixing chamber 110 is a rectangular box with an opening on its top surface for easy feeding of pig feed to be mixed. The bottom surface of the mixing chamber 110 is provided with a baffle 111 and a baffle 112. The opposite ends of the baffles 111 and 112 are rotatably connected to the two inner side walls of the mixing chamber 110. The bottom surface of the mixing chamber 110 is symmetrically equipped with two rotating shafts. The ends of baffle 111 and baffle 212 that are far apart are rotatably connected to the two rotating shafts respectively. The bottom surfaces of baffle 111 and baffle 212 are each fixedly connected with two rotating seats 113. Two stirring shafts 120 are provided, which are symmetrically arranged and penetrate through the interior of the mixing chamber 110. The outer walls of the two stirring shafts 120 are provided with several stirring blades 121. Gears 122 are sleeved and fixedly fitted onto the outer walls of the two stirring shafts 120 located outside the mixing chamber 110. The unit is also covered by a protective shell. Two gears 122 mesh for transmission. The feed distribution box 130 is located below the mixing box 110, and its top surface has an opening. The bottom of the mixing box 110 is inserted into the top of the feed distribution box 130. The feed distribution box 130 is used to receive the mixed feed. The bottom surface of the feed distribution box 130 has two discharge ports 131, which are inclined to both sides. Four electric telescopic rods 140 are provided, arranged symmetrically in pairs. The output ends of the four electric telescopic rods 140 are rotatably connected to the interior of four rotating seats 113. Two side frames 150 are provided, also symmetrically. Both side frames 150 include L-shaped bases 153. Movable plates 151 are slidably inserted into the top surfaces of both L-shaped bases 153. The two movable plates 151 are connected to the mixing box 110. The two L-shaped bases 153 are connected to the distributing box 130. A drive motor 160 is fixedly connected to the outer wall of one of the movable plates 151. The motor shaft of the drive motor 160 is connected to the end of one of the stirring shafts 120. Electric telescopic rods 180 are fixedly connected to the bottom surfaces of both L-shaped bases 153. The output ends of the two electric telescopic rods 180 are fixedly connected to the bottom surfaces of the two movable plates 151 respectively.

[0032] Specifically, during operation, all four electric telescopic rods 140 are in the extended state by default, causing baffles 111 and 112 to be horizontally abutted against the bottom surface of the mixing chamber 110, thus sealing the bottom of the mixing chamber 110. The feed to be mixed is then added into the mixing chamber 110 from the top surface. The drive motor 160 is started, and its motor shaft drives one of the stirring shafts 120. The stirring shaft 120 drives its corresponding gear 122 to rotate. The two gears 122 mesh, causing the two stirring shafts 120 to rotate in opposite directions, resulting in the stirring blades 121 mixing the feed. After mixing, the four electric telescopic rods 140 are retracted, allowing the feed to... Baffle 111 and baffle 212 are rotated to be perpendicular to the ground, causing the bottom of the mixing box 110 to open. This allows the feed inside the mixing box 110 to fall naturally into the distribution box 130 under gravity, and then be discharged in two batches from the two discharge ports 131. When cleaning is required, the two electric telescopic rods 2180 can be extended. The two electric telescopic rods 2180 push the two moving plates 151 upward, causing the mixing box 110 to move upward. This separates the bottom of the mixing box 110 from the top of the distribution box 130. At this time, the inside of the mixing box 110 and the distribution box 130 can be brushed and swept by the rod-shaped cleaning device to remove the feed dust adhering to their inner walls.

[0033] like Figure 2 and Figure 4 As shown, in this embodiment, a docking groove 1111 is provided on the top surface of baffle 111 near baffle 2 112, and a docking groove 2 1121 is provided on the bottom surface of baffle 2 111 near baffle 111. The docking groove 2 1121 fits into baffle 111. Two opposite inner sidewalls of mixing box 110 are provided with guide plates 114. The guide plates 114 are located inside mixing box 110 near the bottom surface. The cross-section of guide plate 114 is triangular. When baffle 111 and baffle 2 112 are closed, their top surfaces contact the bottom surface of guide plate 114. A conical boss 133 is provided inside the material distribution box 130 at the center of the two discharge ports 131.

[0034] In this embodiment, when it is necessary to seal the bottom of the mixing box 110, the second baffle 112 can be flipped first, and then the first baffle 111 can be flipped, so that the first docking groove 1111 and the second docking groove 1121 fit together, preventing feed from leaking out from the joint of the first baffle 111 and the second baffle 112. The guide plate 114 is set at the position where the mixing box 110 rotates and connects with the first baffle 111 or the second baffle 112. Its tilt angle causes the feed to move towards the center of the first baffle 111 and the second baffle 112, preventing the feed from getting stuck at the joint of the rotating shaft. The top of the conical boss 133 is a sharp corner, which reduces the residue of feed in the distribution box 130.

[0035] like Figure 5As shown, in this embodiment, the top surface of the L-shaped base 153 is provided with a plug-in groove, and the bottom surface of the movable plate 151 is fixedly connected with a plug-in plate 152 that slides into the plug-in groove. Both movable plates 151 are fixedly connected to the mixing box 110 through a first fixing bracket 1511, and both L-shaped bases 153 are fixedly connected to the dispensing box 130 through a second fixing bracket 1531. The first fixing bracket 1511 is fixedly connected to the inner sidewall of the two movable plates 151, and the second fixing bracket 1531 is fixedly connected to the inner sidewall of the two L-shaped bases 153. The first fixing bracket 1511 and the second fixing bracket 1531 are detachably fixed to the mixing box 110 and the dispensing box 130 by bolts.

[0036] In practice, when it is necessary to clean the inside of the mixing box 110 and the dispensing box 130, the two electric telescopic rods 180 are extended, causing the moving plate 151 to move upward and the plug-in plate 152 to move upward from the inside of the L-shaped base 153, thereby driving the mixing box 110 to move upward stably.

[0037] like Figure 2-3 and Figure 5 As shown, in this embodiment, connecting rods 170 are provided on both sides of the two movable plates 151. The two ends of the connecting rods 170 are fixedly connected to the side walls of the two movable plates 151 respectively. Two rotating seats 171 are fixedly connected to the inner side walls of the two connecting rods 170 respectively. The four rotating seats 171 are rotatably connected to the bottom ends of the four electric telescopic rods 140 respectively. U-shaped grooves 132 are provided on the two opposite side walls of the material distribution box 130 at the positions corresponding to the electric telescopic rods 140.

[0038] In practice, the two connecting rods 170 enhance the connection strength of the two moving plates 151. When the electric telescopic rod 180 pushes the moving plate 151 upward, the connecting rod 170 will also move upward along with the moving plate 151 and the mixing box 110. The U-shaped groove 132 provides a moving path for the electric telescopic rod 140. When feeding, the baffle 111 and the baffle 212 will flip downward and cover the U-shaped groove 132 to prevent feed from leaking out of the U-shaped groove 132.
