Description

Technical Field

[0001] This utility model relates to the field of slurry feed production technology, and more specifically, to a slurry feed rotary mixing device. Background Technology

[0002] A rotary mixing device for slurry feed, also commonly known as a liquid feed mixing tank, porridge mixing tank, or TMR liquid mixer, is a specialized mechanical device used to mix dry feed ingredients with water or other liquid ingredients in a specific ratio to prepare a uniform fluid feed. For example, the feed mixer proposed in publication number "CN220878580U" includes a straight rod and a mixing box body. A first bearing is provided at the upper end of the straight rod, which is movably connected to a drive device that drives the straight rod and the mixing box body to rotate. A second bearing is provided at the end of the straight rod near the first bearing, which is movably connected to the mixing box body. The mixing box body is also fixedly connected to the drive device. Stirring rods are arranged in an array on both the straight rod and the inner side of the mixing box body. The lower part of the mixing box body is slidably connected to a base with a sliding rail groove. A pressure telescopic rod is provided at the center of the upper part of the base plate, and a carrying plate is provided at the upper end of the pressure telescopic rod.

[0003] However, in the above technical solutions, since the stirring rods of the feed mixers are all arranged radially perpendicular to the rotation axis, their movement trajectory is a coaxial circular motion, which causes the pushing effect on the material to mainly occur in the horizontal plane, and lacks effective axial lifting and turning capabilities. As a result, for material combinations with large differences in density and particle size, axial stratification is likely to occur during the mixing process. Utility Model Content

[0004] The main purpose of this utility model is to provide a rotary mixing device for slurry feed, which can effectively solve the problem that in the feed mixers of the background art, the stirring rods are all arranged radially perpendicular to the rotation axis, and their movement trajectory is coaxial circular motion, which causes the pushing effect on the material to mainly occur in the horizontal plane, and lacks effective axial lifting and turning ability. As a result, for material combinations with large differences in density and particle size, axial stratification is likely to occur during the mixing process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rotary mixing device for slurry feed includes a base, a support frame fixedly installed on the upper surface of the base, a feed hopper rotatably installed inside the support frame, a feed pipe provided on the outer wall of the feed hopper, and a discharge pipe provided at the lower end of the feed hopper.

[0007] The top of the material barrel has a through hole, and a rotating column is rotatably installed in the through hole through a sealed bearing. Several first stirring rods are fixedly installed on the body of the rotating column.

[0008] A plurality of second stirring rods are rotatably mounted through the inner wall of the material barrel. Each second stirring rod is provided with a plurality of stirring bars. A first bevel gear is fitted on the side of each second stirring rod away from the corresponding stirring bar. Control components for controlling the rotation of the corresponding second stirring rods are provided on both sides of the support frame.

[0009] Preferably, the control component includes an annular frame, which is fixedly installed on a corresponding side of the support frame. A bevel gear ring is fixedly installed on the inner wall of the annular frame, and the bevel gear ring meshes with the corresponding first bevel gear.

[0010] Preferably, the stirring rod includes a vertical rod, which is rotatably mounted on the corresponding second stirring rod body, and an inclined rod is fixedly installed on the upper end of the vertical rod.

[0011] Preferably, each of the second stirring rods has a connecting hole on one end surface, and one end of each upright rod extends into the corresponding connecting hole and is fitted with a second bevel gear.

[0012] Preferably, a number of right-angle frames are fixedly installed on the outer wall of the material bucket, and a horizontal column is fixedly installed on one side of the inner wall of each right-angle frame. Each horizontal column is fitted with two third bevel gears, and each third bevel gear meshes with a corresponding second bevel gear.

[0013] Preferably, a positioning frame is fixedly installed on the upper surface of the support frame, and a motor is fixedly installed on the upper surface of the positioning frame. The output shaft end of the motor passes through the positioning frame and is fixedly connected to the output shaft end of the motor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) When the feed hopper rotates in the opposite direction to the rotating column, the first bevel gear on each second stirring rod meshes with the bevel gear ring fixed on the support frame. While the feed hopper revolves, the first bevel gear drives the second stirring rod to rotate, so that the second stirring rod rotates around its own axis while revolving with the feed hopper.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-5 As shown, a rotary mixing device for slurry feed includes a base 1, a support frame 2 fixedly installed on the upper surface of the base 1, a feed hopper 3 rotatably installed inside the support frame 2, a feed pipe 301 provided on the outer wall of the feed hopper 3, and a discharge pipe 302 provided at the lower end of the feed hopper 3.

[0026] A through hole 4 is provided at the top of the material bucket 3. A rotating column 5 is rotatably installed in the through hole 4 through a sealed bearing. Several first stirring rods 6 are fixedly installed on the body of the rotating column 5.

[0027] A number of second stirring rods 7 are rotatably installed through the inner wall of the material barrel 3. Each second stirring rod 7 is provided with a number of stirring bars 8. A first bevel gear 9 is sleeved on the side of each second stirring rod 7 away from the corresponding stirring bar 8. Control components 10 for controlling the rotation of the corresponding second stirring rod 7 are provided on both sides of the support frame 2.

[0028] The control component 10 includes a ring frame 1001, which is fixedly installed on the corresponding side of the support frame 2. A bevel gear ring 1002 is fixedly installed on the inner wall of the ring frame 1001, and the bevel gear ring 1002 meshes with the corresponding first bevel gear 9.

[0029] A positioning frame 201 is fixedly installed on the upper surface of the support frame 2. A motor 16 is fixedly installed on the upper surface of the positioning frame 201. The output shaft end of the motor 16 passes through the positioning frame 201 and is fixedly connected to the output shaft end of the motor 16.

[0030] A first pulley 17 is fitted on one side of the rotating column 5. A column 18 is rotatably installed on one side of the top of the positioning frame 201. A second pulley 19 is fitted on the column body of the column 18. The first pulley 17 and the second pulley 19 are driven by a belt 20.

[0031] A gear 21 is fitted on the side of the column 18 away from the second pulley 19. An external gear ring 23 is fixedly installed on the upper end of the material bucket 3 by several limiting posts 22. The gear 21 meshes with the external gear ring 23.

[0032] Dry feed ingredients and liquid ingredients such as water are fed into the feed hopper 3 through the feed pipe 301. The motor 16 is started, and the output shaft of the motor 16 drives the rotating column 5 to start rotating, which in turn causes the first stirring rods 6 fixed on it to rotate in the central area of ​​the feed hopper 3, producing a preliminary shearing and stirring effect on the material. At the same time, the output shaft of the motor 16 transmits power to the column 18 through the transmission of the first pulley 17, the belt 20 and the second pulley 19, causing the column 18 to rotate. The gear 21 fixed on the column 18 rotates accordingly. Since the gear 21 meshes with the outer toothed ring 23 fixed on the upper end of the feed hopper 3, it drives the entire feed hopper 3 to rotate in the opposite direction of rotation to the rotating column 5. The first bevel gear 9 on each second stirring rod 7 meshes with the bevel gear ring 1002 fixed on the support frame 2. While the feed hopper 3 revolves, the first bevel gear 9 drives the second stirring rod 7 to rotate, so that the second stirring rod 7 rotates around its own axis while revolving with the feed hopper 3. This allows the first stirring rod 6 and the second stirring rod 7 to horizontally stir the feed, while the stirring rod 8 can axially stir the material, avoiding axial stratification during the mixing process.

[0033] In another embodiment of the present invention, the stirring rod 8 includes a vertical rod 801, which is rotatably mounted on the body of the corresponding second stirring rod 7, and a diagonal rod 802 is fixedly installed on the upper end of the vertical rod 801.

[0034] Each of the second stirring rods 7 has a connection hole 11 on one end surface, and each of the upright rods 801 has one end extending into the corresponding connection hole 11 and fitted with a second bevel gear 12.

[0035] Several right-angle frames 13 are fixedly installed on the outer wall of the material bucket 3. A horizontal column 14 is fixedly installed on one side of the inner wall of each right-angle frame 13. Two third bevel gears 15 are sleeved on the column body of each horizontal column 14. Each third bevel gear 15 meshes with the corresponding second bevel gear 12.

[0036] When the second stirring rod 7 rotates and drives the second bevel gear 12 to revolve, the third bevel gear 15 meshes with the second bevel gear 12, causing the second bevel gear 12 to rotate on its own axis while revolving around the axis of the second stirring rod 7. This causes the upright rod 801 to drive the inclined rod 802 to rotate, allowing the rotating inclined rod 802 to further stir the feed and enhance the stirring effect.

[0037] The working principle of this rotary mixing device for slurry feed:

[0038] In use, dry feed ingredients and liquid ingredients such as water are fed into the feed hopper 3 through the feed pipe 301. The motor 16 is started, and the output shaft of the motor 16 drives the rotating column 5 to start rotating, which in turn causes the first stirring rods 6 fixed on it to rotate in the central area of ​​the feed hopper 3, producing a preliminary shearing and stirring effect on the material. At the same time, the output shaft of the motor 16 transmits power to the column 18 through the transmission of the first pulley 17, the belt 20 and the second pulley 19, causing the column 18 to rotate. The gear 21 fixed on the column 18 rotates accordingly. Since the gear 21 meshes with the outer toothed ring 23 fixed on the upper end of the feed hopper 3, it drives the entire feed hopper 3 to rotate in the opposite direction of rotation to the rotating column 5. The first bevel gear 9 on each second stirring rod 7 meshes with the bevel gear ring 1002 fixed on the support frame 2. While the feed hopper 3 revolves, the first bevel gear 9 drives the second stirring rod 7 to rotate, so that the second stirring rod 7 rotates around its own axis while revolving with the feed hopper 3. This allows the first stirring rod 6 and the second stirring rod 7 to horizontally stir the feed, while the stirring rod 8 can axially stir the material, avoiding axial stratification during the mixing process.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
