Description

Technical Field

[0001] This utility model relates to the field of feed additive processing technology, and in particular to a high-efficiency mixer for solid mixed feed additives. Background Technology

[0002] The processing of mixed feed additives requires mixing multiple solid feed additives in a certain proportion. This mixing requires a mixed feed additive mixer. Existing mixed feed additive mixers include a mixing tank and a stirring shaft inside the mixing tank. After mixing one type of mixed feed additive, to avoid cross-contamination, the machine must be stopped to clean the residue remaining on the inner wall of the mixing tank and the stirring shaft. The complex structure of the stirring blades on the stirring shaft increases the difficulty of cleaning, requiring a long downtime for thorough cleaning before another type of mixed feed additive can be mixed. This makes it impossible to produce different mixed feed additives without stopping the machine, thus reducing the production efficiency of mixed feed additives. Utility Model Content

[0003] This utility model proposes a high-efficiency mixer for solid mixed feed additives. Through the cooperation of the clutch drive component and the end face ratchet, two stirring shafts are alternately connected to the drive shaft, thereby enabling two independent mixing boxes to perform alternating mixing operations, thus realizing non-stop mixing processing of different types of mixed feed additives.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A high-efficiency mixer for solid mixed feed additives includes a housing, which comprises an integral drive housing and two mixing tanks. The drive housing is positioned between the two mixing tanks. Each of the two mixing tanks has a feed inlet at its top and a discharge outlet at its bottom. A stirring shaft is rotatably mounted inside each of the two mixing tanks. The inner ends of both stirring shafts extend into the drive housing and are respectively fixedly mounted with a driven ratchet. A drive shaft is slidably mounted horizontally within the drive housing via a guide frame. The drive shaft is coaxial with the two stirring shafts. A driving ratchet is fixedly mounted at each end of the drive shaft. The drive housing includes a clutch drive assembly for separating and engaging the driving and driven ratchets. A drive motor is fixedly mounted within the drive housing, and the drive shaft is connected to the motor shaft of the drive motor via a bevel gear pair.

[0006] As a preferred technical solution, the clutch drive assembly includes a drive arm hinged to the drive housing, one end of the drive arm is hinged to a bearing housing, the bearing in the bearing housing is fixedly installed on the drive shaft, the drive housing is provided with two positioning holes, and a positioning pin adapted to the positioning holes is provided between the drive arm and the mixing tank.

[0007] As a preferred technical solution, the bevel gear pair includes a matching driving bevel gear and two driven bevel gears. Both driven bevel gears are fixedly mounted on the drive shaft, and the conical surfaces of the two driven bevel gears are arranged opposite each other. The driving bevel gear is fixedly mounted on the motor shaft of the drive motor and located between the two driven bevel gears. The two driven bevel gears alternately mesh with the driving bevel gear.

[0008] As a preferred technical solution, each of the active end face ratchet and the adjacent driven end face ratchet are respectively provided with matching one-way ratchet teeth on their opposite end faces, and the inclination directions of the one-way ratchet teeth on the two active end face ratchets are opposite.

[0009] As a preferred technical solution, a spiral blade assembly is fixedly installed on both of the stirring shafts. The spiral blade assembly includes a first spiral blade and a second spiral blade, and the first spiral blade and the second spiral blade rotate in opposite directions.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0011] Because the high-efficiency mixer for solid mixed feed additives includes a drive box and two mixing bins, a clutch drive assembly engages one of the active end face ratchet wheels with the adjacent driven end face ratchet wheel. Under the action of the drive motor and bevel gear pair, the stirring shaft mixes the mixed feed additives in the mixing bins. After mixing and discharging, the clutch drive assembly engages the other active end face ratchet wheel with the adjacent driven end face ratchet wheel. Under the action of the drive motor and bevel gear pair, the other stirring shaft processes another type of mixed feed additive. This allows for rapid switching between the production of different mixed feed additives without stopping the machine, avoiding the low production efficiency problem caused by the shutdown for cleaning of existing mixers.

[0012] Since the high-efficiency mixer for solid mixed feed additives includes a clutch drive assembly, after a mixed feed additive is mixed, the positioning pin is pulled out, the drive arm is rotated, and the drive shaft moves axially. Since the drive shaft is coaxially set with two other drive shafts, the clutch drive assembly allows the drive shaft to move axially, enabling the two active end face ratchet wheels to alternately engage with the adjacent driven end face ratchet wheels. After engagement, the drive shaft and the corresponding stirring shaft are connected for transmission.

[0013] When one of the active end face ratchet wheels engages with the adjacent driven end face ratchet wheel, the other active end face ratchet wheel disengages from the adjacent driven end face ratchet wheel, thereby realizing the alternating transmission connection between the drive shaft and the two mixing shafts, and thus realizing the alternating mixing operation of the two mixing bins, thereby realizing the non-stop processing of different types of mixed feed additives.

[0014] A bevel gear pair consists of a driving bevel gear and two driven bevel gears. As the drive shaft moves axially, the driving gear alternately meshes with the two driven gears. The bevel gear pair arrangement ensures that the drive shaft remains connected to the drive motor before and after axial movement. Attached Figure Description

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.

[0023] like Figures 1-5 As shown, a high-efficiency mixer for solid mixed feed additives includes a housing 1. The housing 1 includes a drive housing 2 and two mixing tanks 3 integrated into one unit. The drive housing 2 is located between the two mixing tanks 3. Each of the two mixing tanks 3 has a feed inlet 4 at its top and a discharge outlet 5 at its bottom. A stirring shaft 6 is rotatably installed inside each of the two mixing tanks 3. The inner ends of the two stirring shafts 6 extend into the drive housing 2 and are respectively fixedly mounted with a driven end face ratchet 7. A drive shaft 9 is slidably installed in the drive housing 2 along the horizontal direction via a guide frame 8. The drive shaft 9 is coaxial with the two stirring shafts 6. A driving end face ratchet 10 is fixedly installed at both ends of the drive shaft 9. The drive housing 2 is provided with a clutch drive assembly for separating and engaging the driving end face ratchet 10 and the driven end face ratchet 7. A drive motor 11 is fixedly installed in the drive housing 2. The drive shaft 9 is connected to the motor shaft of the drive motor 11 via a bevel gear pair.

[0024] The clutch drive assembly includes a drive arm 12 hinged in the drive housing 2. One end of the drive arm 12 is hinged to a bearing housing 13. The bearing 14 in the bearing housing 13 is fixedly installed on the drive shaft 9. The drive housing 2 is provided with two positioning holes 15. A positioning pin 16 that matches the positioning holes 15 is provided between the drive arm 12 and the mixing box 3.

[0025] like Figure 2 As shown, one of the stirring shafts 6 is in operation, as... Figure 5 As shown, another stirring shaft 6 is in working condition. This utility model locks the drive arm 12 through the cooperation of the positioning hole 15 and the positioning pin 16, so that the active end face ratchet 10 and the corresponding driven end face ratchet 7 are in a stable engagement state, providing power for the rotation of the corresponding stirring shaft 6.

[0026] The bevel gear pair includes a matching driving bevel gear 17 and two driven bevel gears 18. Both driven bevel gears 18 are fixedly mounted on the drive shaft 9, and the conical surfaces of the two driven bevel gears 18 are arranged opposite each other. The driving bevel gear 17 is fixedly mounted on the motor shaft of the drive motor 11 and located between the two driven bevel gears 18. The two driven bevel gears 18 alternately mesh with the driving bevel gear 17.

[0027] Each active end face ratchet 10 and the adjacent driven end face ratchet 7 are respectively provided with a matching one-way ratchet 19 on their opposite end faces, and the inclination directions of the one-way ratchet 19 on the two active end face ratchet 10s are opposite.

[0028] Since the drive motor 11 transmits power to the drive shaft 9 through the driving bevel gear 17 and the driven bevel gear 18, and the drive shaft 9 then transmits power to the corresponding stirring shaft 6, such as... Figure 2 and Figure 5 As shown, the bevel gears are arranged so that the two stirring shafts 6 rotate in opposite directions, so the tilting directions of the one-way ratchet 19 on the two active end face ratchet 10 are set to be opposite.

[0029] Both stirring shafts 6 are fixedly equipped with helical blade assemblies, which include a first helical blade 20 and a second helical blade 21. The first helical blade 20 and the second helical blade 21 rotate in opposite directions. Under the action of the first helical blade 20 and the second helical blade 21 with opposite rotation directions, the material is mixed and then conveyed to the corresponding discharge port 5 after mixing.

[0030] The top of the drive box 2 is open, and a butterfly valve 22 is provided at each discharge port 5.

[0031] In summary, this utility model uses a clutch drive assembly and an end-face ratchet to enable two stirring shafts to be alternately connected to the drive shaft, thereby allowing two independent mixing bins to perform alternating mixing operations, thus realizing non-stop mixing processing of different types of mixed feed additives.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
