Description

Technical Field

[0001] This utility model relates to the field of feed mixing technology, and in particular to a feed mixing and stirring device. Background Technology

[0002] Feed is a general term for the food of animals raised by all people. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. In the process of feed production, the formula can be changed according to the different types of animals being raised. Then, the various raw materials are thoroughly mixed through a feed mixing device to complete the feed production.

[0003] In existing feed mixers, the outer side of the mixer shaft is welded with fixed screw blades and supporting rods. However, when this mixing structure needs to be replaced due to different production plans or wear of the screw blades and supporting rods, the mixer usually needs to disassemble the drive structure and support structure of the mixing shaft, and also needs to pull the mixing shaft. This makes the mixing structure of the mixer inconvenient to maintain during use and cannot meet the production needs of feed mixing production personnel. Therefore, we propose a feed mixing device. Utility Model Content

[0004] The main objective of this invention is to provide a feed mixing and stirring device. By disassembling the traditional integrated stirring shaft of the mixer body into a driven shaft, a supported shaft, and a shaft tube assembly, a modular stirring shaft mechanism that can be assembled in a modular fashion is created. The driven shaft, supported shaft, and shaft tube assembly are quickly positioned using a D-shaped and fixed rib clamping structure between the shaft support plate and the core pressure plate, and are easily locked with bolts and nuts. This eliminates the need to disassemble the drive-end reducer or the bearing seat at the support shaft end when replacing the stirring structure of the mixer body. Only the bolts at the core pressure plate and shaft support plate need to be removed, and the shaft tube assembly can be lifted and replaced as a whole using a T-shaped lifting rod. This simplifies the maintenance process of the mixer body's stirring structure from disassembling and pulling the shaft to lifting and replacement, solving the pain point of requiring complete disassembly of the mixer body when replacing the stirring structure. Furthermore, this modular shaft tube can be customized with multiple sets of tubes with different stirring structures, thus easily adapting to the stirring needs of various products such as livestock and poultry feed and aquatic feed, effectively solving the problems in the background art.

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

[0006] A feed mixing and stirring device includes a mixer body and a modular stirring shaft mechanism. The modular stirring shaft mechanism includes a driven shaft, a supported shaft, a shaft support plate, a core pressure plate, a support plate, a core shaft, and a shaft tube. The driven shaft and the supported shaft have a shaft support plate integrally formed on one side of their bodies. The bottom of the shaft support plate has a U-shaped support block protruding downwards for mounting D-shaped inserts. The upper part of the shaft support plate away from the U-shaped support block has symmetrically formed slots for mounting fixed inserts. The D-shaped inserts are integrally formed on the core pressure plate. On the lower plate surface, the core pressure plate above the D-shaped insert has symmetrically raised fixed inserts, and the top of the core pressure plate between the D-shaped inserts is welded with an L-shaped fastener for fastening the shaft support plate. The opposing plates of the core pressure plate and the shaft support plate are locked with bolts and nuts, and the core pressure plate is symmetrically welded to both ends of the shaft tube. The outer side of the shaft tube is welded with a spiral blade. The opposing plates of the core pressure plate are welded with a core shaft through a support plate. The driven shaft and the supported shaft are respectively installed at the drive end and the support shaft end of the mixer body.

[0007] Furthermore, mounting holes are provided at four points on the opposing surfaces of the core pressure plate and the shaft support plate, and bolts pass through the mounting holes of the core pressure plate and the shaft support plate and are screwed onto the nuts.

[0008] By adopting the above technical solution, the mounting holes of the core pressure plate and the shaft support plate can be screwed through with bolts and nuts, thereby locking the core pressure plate and the shaft support plate.

[0009] Furthermore, the U-shaped support block has a recessed D-shaped groove on its surface, and a D-shaped insert is fitted inside the D-shaped groove.

[0010] By adopting the above technical solution, the U-shaped support block can be positioned and inserted by using the D-shaped slot to hold the D-shaped insert.

[0011] Furthermore, the cavity of the fixed slot gradually expands from bottom to top, and the fixed insertion ribs inside the fixed slot gradually shrink from top to bottom;

[0012] By adopting the above technical solution, the tapered rib of the fixed insertion rib can be fitted and installed in the tapered groove of the fixed slot.

[0013] Furthermore, the mandrel has cross-shaped reinforcing plates welded to both ends of the shaft, and the arc-shaped outer surface of the reinforcing plates is welded inside the plate hole of the core pressure plate, and the reinforcing plates protrude from the outer plate of the core pressure plate and are welded to the inner wall of the shaft tube.

[0014] By adopting the above technical solution, the mandrel is connected to the core pressure plate and the shaft tube by welding the support plate.

[0015] Furthermore, the upper surface of the L-shaped buckle is welded with the vertical column of the T-shaped lifting rod, and the top of the vertical column of the T-shaped lifting rod is integrally formed with a horizontal handle;

[0016] By adopting the above technical solution, after welding the T-shaped lifting rod to the L-shaped buckle plate, the L-shaped buckle plate, core pressure plate and shaft tube can be lifted by holding the horizontal handle and vertical column of the T-shaped lifting rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention breaks down the traditional integrated mixing shaft of a mixer into a driven shaft, a supported shaft, and a shaft tube assembly, and sets up a modular mixing shaft mechanism that can be assembled in a modular fashion. The driven shaft, supported shaft, and shaft tube assembly are quickly positioned by the D-shaped insert and fixed insert clamping structure of the shaft support plate and the core pressure plate, and are simply locked with bolts and nuts. This allows the mixer body to replace the mixing structure without disassembling the drive end reducer or the bearing seat of the support shaft. Only the bolts at the core pressure plate and the shaft support plate need to be removed, and the shaft tube assembly can be taken away as a whole by the T-shaped lifting rod for replacement. This simplifies the maintenance process of the mixing structure of the mixer body from disassembling and pulling the shaft to hoisting and replacing, solving the pain point of having to disassemble the entire mixer body to replace the mixing structure.

[0019] Furthermore, this modular shaft tube can be customized into multiple sets of tubes with different mixing structures, thus easily adapting to the mixing needs of various products such as livestock and poultry feed and aquatic feed. The shaft tube has a core shaft inside, which is supported by welded reinforcing plates to ensure its structural strength. Attached Figure Description

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3As shown, a feed mixing and stirring device includes a mixer body 1 and a modular stirring shaft mechanism 2. The modular stirring shaft mechanism 2 includes a driven shaft 3, a supported shaft 4, a shaft support plate 5, a core pressure plate 8, a support rib plate 13, a core shaft 14, and a shaft tube 15. The driven shaft 3 and the supported shaft 4 have a shaft support plate 5 integrally formed on one side of their shaft bodies. The bottom of the shaft support plate 5 has a U-shaped support block 6 for mounting D-shaped inserts 9. The upper body of the shaft support plate 5 away from the U-shaped support block 6 has symmetrically formed fixed slots 7 for mounting fixed inserts 10. The D-shaped inserts 9 are integrally formed on the core pressure plate. On the lower surface of plate 8, the core pressure plate 8 above the D-shaped insert 9 has symmetrically raised fixed insert ribs 10, and the top of the core pressure plate 8 between the D-shaped insert ribs 9 is welded with an L-shaped buckle plate 11 for fastening the shaft support plate 5. The opposing plates of the core pressure plate 8 and the shaft support plate 5 are locked by bolts and nuts, and the core pressure plate 8 is symmetrically welded to both ends of the shaft tube 15. The outer side of the shaft tube 15 is welded with a spiral blade 16. The opposing plates of the core pressure plate 8 are welded with a mandrel 14 through a support plate 13. The driven shaft 3 and the supported shaft 4 are respectively installed at the drive end and the support shaft end of the mixer body 1.

[0026] The core pressure plate 8 and the shaft support plate 5 have four mounting holes on their opposing surfaces, and bolts pass through the mounting holes of the core pressure plate 8 and the shaft support plate 5 and are screwed to the nuts.

[0027] By adopting the above technical solution, the mounting holes of the core pressure plate 8 and the shaft support plate 5 can be screwed through with bolts and nuts, thereby locking the core pressure plate 8 and the shaft support plate 5.

[0028] The U-shaped support block 6 has a recessed D-shaped groove on its surface, and a D-shaped insert 9 is fitted inside the D-shaped groove.

[0029] By adopting the above technical solution, the U-shaped support block 6 can be positioned and inserted by using the D-shaped slot to hold the D-shaped insert 9.

[0030] The cavity of the fixed slot 7 gradually expands from bottom to top, and the fixed insertion rib 10 inside the fixed slot 7 gradually shrinks from top to bottom.

[0031] By adopting the above technical solution, the tapered rib of the fixed insertion rib 10 can be fitted and installed in the tapered groove of the fixed slot 7.

[0032] Among them, the mandrel 14 has cross-shaped reinforcing plates 13 welded at both ends of the shaft body, and the arc-shaped outer plate surface of the reinforcing plate 13 is welded in the plate hole of the core pressure plate 8, and the reinforcing plate 13 is exposed outside the outer plate of the core pressure plate 8 and welded to the inner tube wall of the shaft tube 15.

[0033] By adopting the above technical solution, the mandrel 14 is connected to the core pressure plate 8 and the shaft tube 15 by welding the support plate 13.

[0034] The upper surface of the L-shaped buckle plate 11 is welded with the vertical column of the T-shaped lifting rod 12, and the top of the vertical column of the T-shaped lifting rod 12 is integrally formed with a horizontal handle.

[0035] By adopting the above technical solution, after welding the T-shaped lifting rod 12 to the L-shaped buckle plate 11, the L-shaped buckle plate 11, the core pressure plate 8 and the shaft tube 15 can be lifted by holding the horizontal handle and vertical column of the T-shaped lifting rod 12.

[0036] It should be noted that this utility model is a feed mixing and stirring device. The original stirring shaft structure of the mixer body 1 is disassembled into a modular stirring shaft mechanism 2 consisting of a driven shaft 3, a supporting shaft 4, a shaft tube 15, and a spiral blade 16. Shaft support plates 5 for assembling the shaft tube 15 are then installed at the driven shaft 3 and the supporting shaft 4. The driven shaft 3 can pass through the original drive end shaft hole of the mixer body 1 to connect to a reducer. The reducer's pulley can be connected to a motor with a pulley for drive via a belt. The supporting shaft 4 passes through the other end of the mixer body 1 and is supported by a bearing seat with an internal bearing. Finally, a core pressure plate 8 is symmetrically welded to the shaft tube 1. 5. At this time, the mandrel 14 extends out of the shaft tube 15. The two ends of the mandrel 14 are connected to the shaft tube 15 by welding the core pressure plate 8 with the support plate 13. The outer side of the shaft tube 15 can be normally welded with the screw blade 16. The shaft tube 15 can be lifted by holding the T-shaped lifting rod 12. The mixer body 1 can be customized with multiple sets of shaft tubes 15. Various mixing structures suitable for different mixing needs can be welded and installed on the outer side of these shaft tubes 15. When the mixer body 1 needs to assemble the mixing structure, simply put the shaft tube 15 into the mixer body 1, so that the driven shaft 3 and the supported shaft 4 are in a vertical installation state, ensuring that the D-shaped groove of the U-shaped support block 6 is facing upward. Then the shaft tube 15 is supported by the D-shaped groove of the core pressure plate 8. The insert rib 9 is engaged with the U-shaped support block 6 below the shaft support plate 5 of the driven shaft 3 and the supported shaft 4. At this time, the fixed insert rib 10 of the core pressure plate 8 is inserted and positioned in the fixed slot 7 of the shaft support plate 5. Then, a bolt is passed from the mounting hole on the back of the core pressure plate 8 to the mounting hole on the shaft support plate 5, and a nut is inserted between the shaft support plate 5 and the inner wall of the mixer body 1 so that the bolt can be screwed into the nut, thereby assembling the core pressure plate 8 and the shaft support plate 5. If sealing is required, a rubber block adapted to its cavity shape can be filled between the core shaft 14 and the support plate 13 for adhesive sealing, thereby sealing the cavity between the core pressure plate 8 and the core shaft 14 and the support plate 13. When the mixer body 1 is in operation, the drive module stirring shaft mechanism 2 can be rotated normally, causing the spiral blades or other customized stirring structures outside the shaft tube 15 to rotate and mix the feed. If it is necessary to replace the stirring structure, simply clean the inside of the mixer body 1, so that the T-shaped lifting rod 12 faces the opening of the mixer body 1, and then manually remove the bolts and nuts at the core pressure plate 8 and shaft support plate 5 with a wrench. As the bolts are pulled out, the shaft tube 15 can be lifted upward by holding the T-shaped lifting rod 12, so as to take the shaft tube 15 of other customized stirring structures and reinstall it according to the above steps, which facilitates the convenient replacement of the stirring structure inside the mixer body 1.
