Description

Technical Field

[0001] The utility model relates to the technical field of mixing, in particular to a closed mixing device. Background Art

[0002] Mixed biological feed is made by mixing different types of feed in proportion. Sometimes additives are also needed to be added to the feed, including solid feed additives and liquid feed additives.

[0003] Traditionally, the production and processing of solid feed is carried out in an open space. However, under current conditions, in order to reduce the negative impact of other factors on mixed and processed feed, a closed structure is gradually adopted. For example, a spiral double-shaft mixer for feed mixing is disclosed in announcement number CN218688646U, which rotates the L-shaped support rod and the mixing blades to stir the various feeds inside the mixing drum to mix the various feeds. The rotation of the spiral blades can make the feed in the mixing drum enter from the lower port of the guide drum and be discharged from the upper port, and transport the feed at the bottom layer of the mixing drum to the upper layer, thereby avoiding stratification. However, it lacks supporting pretreatment for various raw materials with large individual differences. The raw materials are only stirred and driven by the L-shaped support rod, which is very likely to cause stratification and accumulation, and cannot ensure that various raw materials of different sizes can be fully and comprehensively mixed.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 4 A closed mixing device includes a chassis 1, which is provided with an upper cavity 101 and a lower cavity 102 connected to each other. A mesh connecting the upper cavity 101 and the lower cavity 102 is provided in the middle end of the chassis 1. The animal feed raw materials that are initially crushed in the upper cavity 101 are converted into animal feed crumbs and then enter the lower cavity 102 through the mesh. A sealing cover plate 2 corresponding to the upper cavity 101 is hinged on the chassis 1, and an operation window 3 connecting to the lower cavity 102 is provided at the lower end of the chassis 1. It is worth noting that the operation window 3 corresponds horizontally to the opening in the side wall of the mixing drum 15, and an openable and closable glass window is hinged in the operation window 3 to facilitate manual observation and subsequent material retrieval operations.

[0025] The chassis 1 is equipped with a drive motor 4 and a drive shaft 5 which is driven by the drive motor 4 to rotate and extends into the lower cavity 102. Figure 3 , the driving shaft 5 is driven by the driving motor 4 to rotate.

[0026] The chassis 1 is provided with a crushing mechanism which is connected to the driving shaft 5 through the upper cavity 101 and is used to crush the animal feed raw materials by pressure. Figure 1 With attached Figure 3 The crushing mechanism includes a first boosting cam 6 fixedly mounted on the outer end of the driving shaft 5, and a driving wedge head strip 7 is slidably mounted in the outer wall of the chassis 1 and slidably contacts the first boosting cam 6. A limiting long hole for slidingly sleeved on the first boosting cam 6 is opened in the driving wedge head strip 7 to ensure that the two are always movable against each other, and a sliding sleeve is provided in the chassis 1 with a sliding sleeve that contacts the driving wedge head strip 7 and extends to a driven wedge head strip 8 in the upper cavity 101. A first spring 9 is welded on the driven wedge head strip 8 and is fixedly connected to the chassis 1. The first spring 9 is a tension spring. During the downward movement of the driving wedge head strip 7, the driven wedge head strip 8 is mainly supported by the tension of the first spring 9, and a boosting slider 10 is integrally connected to the driven wedge head strip 8. Under the joint action of the driving wedge head strip 7 and the first spring 9, the boosting slider 10 is reciprocated in the upper cavity 101 to pressurize and crush the animal feed raw materials in the upper cavity 101, so that the crushed animal feed fragments enter the lower cavity 102 through the mesh.

[0027] The chassis 1 is provided with a mixing mechanism which is connected to the driving shaft 5 through the lower cavity 102 and is used to mix the animal feed crushed materials. Figure 2 -Attached Figure 4The mixing mechanism includes a load-bearing sleeve 11 rotatably mounted in the lower cavity 102, and the driving shaft 5 and the load-bearing sleeve 11 are respectively key-connected with a driving gear 13 and a driven gear 14 in meshing connection. The driving gear 13 and the driven gear 14 are both bevel gears. The driving shaft 5 is integrally connected with a mixing drum 15 for loading animal feed crumbs. The mixing drum 15 drives the animal feed crumbs to rotate horizontally. A lifting inner rod 16 extending into the mixing drum 15 is movably sleeved in the load-bearing sleeve 11. The lower end of the lifting inner rod 16 is integrally connected with an extension plate 17, and a second spring 18 is welded between the chassis 1 on the extension plate 17. The second spring 18 is a tension spring. The joint action of the second boosting cam 19 and the second spring 18 causes the lifting inner rod 16 to move between the load-bearing sleeve 11 and the mixing drum 1 5 reciprocates up and down, a second booster cam 19 with a sliding resistance extension plate 17 is fixedly mounted on the driving shaft 5, a guide turntable 20 is fixedly mounted on the lifting inner rod 16, and a rotating ring 21 is rotatably mounted on the guide turntable 20, and a reciprocating push rod 22 is slidably mounted on the rotating ring 21. The guide turntable 20 is synchronously lifted and lowered under the driving action of the lifting inner rod 16, so that the reciprocating push rod 22 can horizontally extend and retract in the rotating ring 21, and a stirring shaft 23 for stirring and driving the animal feed crumbs is pin-connected between the reciprocating push rod 22 and the mixing drum 15. The stirring shaft 23 rotates horizontally with the mixing drum 15, and at the same time, the stirring shaft 23 moves up and down under the traction of the guide turntable 20. The stirring shaft 23 can roll the animal feed crumbs while driving the animal feed crumbs horizontally.

[0028] The driving motor 4 is fixedly mounted on the outer wall of the chassis 1 , and the driving shaft 5 is rotatably mounted on the chassis 1 .

[0029] The boost slider 10 is connected to the inner end of the driven wedge head strip 8 located in the upper cavity 101, and the boost slider 10 is slidably fitted into the mesh. The boost slider 10 applies pressure and crushes the animal feed raw materials during the process of active contact with the mesh, ensuring that the animal feed raw materials can be crushed into animal feed crumbs of uniform specifications.

[0030] The mixing drum 15 is located below the mesh, and a guide slot 12 for movably fitting the second boosting cam 19 is provided at the bottom of the chassis 1 to guide and limit the second boosting cam 19 .

[0031] The guide turntable 20 is a hollow disc structure with uniform openings, and the guide turntable 20 is connected to the top end of the lifting inner rod 16 located in the mixing drum 15.

[0032] It should be noted that the specific model and specifications of the drive motor 4 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0033] The functional principle of this utility model can be explained through the following operation modes:

[0034] The animal feed materials to be mixed are introduced into the upper cavity 101, the sealing cover 2 is controlled to be closed, the drive motor 4 is turned on, and the output end of the drive motor 4 drives the drive shaft 5 to rotate;

[0035] The driving shaft 5 repeatedly applies pressure to the driving wedge strip 7 via the first boosting cam 6, causing the driving wedge strip 7 to squeeze the driven wedge strip 8 during its upward movement. Due to the tension of the first spring 9, the driven wedge strip 8 moves left and right. The boosting slider 10, which moves left and right with the driven wedge strip 8, repeatedly applies pressure and crushes the animal feed material in the upper cavity 101.

[0036] The animal feed scraps enter the lower cavity 102 through the mesh and fall into the mixing drum 15;

[0037] The driving shaft 5 drives the load-bearing sleeve 11 to rotate through the driving gear 13 and the driven gear 14. The load-bearing sleeve 11 supports the mixing drum 15 to rotate synchronously. The mixing drum 15 drives the stirring shaft 23 to rotate to stir the animal feed crumbs.

[0038] The driving shaft 5 repeatedly applies pressure to the extension plate 17 via the second boosting cam 19. Simultaneously, due to the tension of the second spring 18, the lifting inner rod 16 repeatedly rises and falls within the mixing drum 15. The lifting inner rod 16 drives the rotating ring 21 to move up and down via the guide turntable 20. The rotating ring 21 drives the reciprocating push rod 22 to extend and retract horizontally, thereby driving the stirring shaft 23 to repeatedly open and close.

[0039] The stirring shaft 23 , which repeatedly opens and closes and rotates in one direction, stirs the animal feed crumbs comprehensively to ensure that the animal feed crumbs are fully mixed.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
