Abstract
Description
Technical Field
[0001] This utility model relates to agricultural machinery and equipment, specifically a feed mixer. Background Technology
[0002] Existing feed mixers have the following problems: First, the mixing uniformity is poor. When mixing different types and particle sizes of feed ingredients, uneven distribution of ingredients often occurs in some areas, which leads to unbalanced nutrient intake by animals and affects their growth and development; second, the mixing efficiency is low.
[0003] Traditional mixing structures result in a relatively simple movement path for raw materials within the mixing chamber, leading to long mixing times and failing to meet the demands of large-scale farming for rapid feed production. Furthermore, some feed mixers present cleaning challenges. The complex internal structure of the mixing chamber allows feed residue to accumulate in corners and crevices, and incomplete cleaning can breed bacteria, contaminating subsequent batches of feed. Utility Model Content
[0004] The purpose of this invention is to provide a feed mixer that fundamentally solves the above-mentioned problems. It has the advantages of high mixing efficiency, low energy consumption, and easy maintenance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: The feed mixer includes a mixing chamber assembly and a drive assembly fixed on a frame, and its key technical features are: The mixing chamber assembly includes a mixing chamber shell with an observation window, a matching top cover, and a mixing shaft rotatably mounted inside the mixing chamber shell. The top cover is fitted with a top cover bearing, and a mixing shaft bearing seat is fixed on the frame. A mixing shaft bearing is installed inside the mixing shaft bearing seat. Both ends of the mixing shaft are rotatably mounted through the top cover bearing and the mixing shaft bearing. A drive wheel and a hopper drive wheel are coaxially mounted at one end of the mixing shaft that passes through the mixing shaft bearing seat. The mixing chamber shell includes a cylindrical mixing section that serves as the main chamber, a narrowed feeding section, and a connecting section for transitioning between the two parts. The connecting section is provided with a material cylinder outlet and a circulating discharge port. The feeding section is connected to the first hopper and the second hopper, respectively. The drive assembly includes a motor fixed to one side of the frame, with a drive wheel mounted on the output end of the motor, which engages with a driven wheel.
[0006] Furthermore, the mixing shaft is symmetrically fixed with a first and second material-pulling blade with a hollowed-out center on the auger within the connecting section.
[0007] Furthermore, the first hopper is equipped with an air inlet and an air outlet.
[0008] Furthermore, the discharge port of the material cylinder is also equipped with a lifting mechanism, which includes a cylindrical elevator housing, a pressure cover fitted on the top of the elevator housing, a top bearing assembled in the pressure cover, an elevator bearing seat fixed at the bottom of the elevator housing, a bottom bearing assembled in the elevator bearing seat, and an auger assembled at both ends through the top bearing and the bottom bearing respectively.
[0009] Furthermore, a first hopper bearing seat is fixed at the bottom of the first hopper, and a first hopper bearing is assembled inside the first hopper bearing seat. The first hopper driven wheel is installed through the first hopper bearing seat and the rotating shaft. The bottom of the second hopper is fixed with a second hopper bearing seat, and the second hopper bearing is assembled inside the second hopper bearing seat. The second hopper driven wheel is installed through the second hopper bearing seat and the rotating shaft. The driven wheels of the first and second hoppers are simultaneously linked with the driving wheels of the hoppers, and the driving wheels of the hoppers and the driven wheels of the transmission are coaxially arranged.
[0010] The beneficial effects of this utility model are as follows: In terms of the overall technical solution, this utility model uses a double hopper structure to accurately transport feed raw materials into the mixing chamber shell. After the equipment is started, the mixing shaft drives the stirring component to operate, and the material is transferred from the feeding section to the mixing section in a down-up direction along a specific trajectory in the mixing chamber, while completing the continuous stirring and mixing process. After the mixing reaches the standard, the material is directly discharged from the discharge port of the material cylinder.
[0011] In terms of drive method, this utility model adopts a single motor drive scheme, which can simultaneously provide power to the mixing chamber assembly, lifting mechanism, first hopper, and second hopper. The specific transmission path is as follows: the drive wheel at the motor output end is connected to the driven wheel via a transmission belt; the driven wheel is coaxially arranged with the mixing shaft and the driven wheel of the mixing chamber assembly, and rotates synchronously with the driven wheel; the driven wheel of the mixing shaft drives the driven wheels of the first hopper and the second hopper respectively through another set of transmission belts, realizing the coordinated action of multiple actuators.
[0012] To expand the equipment's functionality and applicable scenarios, an additional lifting mechanism can be configured. After the material achieves a uniform mixing effect in the mixing section, it enters the elevator housing through the material cylinder outlet in the connecting section. Driven by the auger conveyor components, the material is transported along the lifting path and finally discharged from the main outlet. Attached Figure Description

[0018] The following combination Figures 1-4 The specific content of this utility model will be described in detail through specific embodiments. Example
[0019] like Figure 1 , Figure 1a , Figure 2 As shown, the feed mixer mainly consists of a mixing chamber assembly 1 fixed to the frame 2, a drive assembly 4, and a matching feeding structure. The components work together to achieve precise mixing and efficient conveying of the feed. The mixing chamber assembly 1 is the core unit for feed mixing and is assembled on the frame 2. It includes a mixing chamber shell 11, a top cover 12 with an exhaust port 122, a mixing shaft 13, and matching connecting parts.
[0020] The mixing chamber shell 11 has a segmented structure, consisting of three parts integrally formed or sealed together. The mixing section 112, as the main chamber, has a cylindrical structure and provides the main mixing space for the feed. The feeding section 114 has a narrowed diameter design and is sealed and connected to the first hopper 315 and the second hopper 316 respectively, for introducing the two feeds to be mixed into the main chamber. The connecting section 113 is used to transition between the mixing section 112 and the feeding section 114, and has a feed cylinder outlet 14 (for discharging the mixed feed) and a circulation discharge port 15 (for partial feed circulation mixing). In addition, the mixing chamber shell 11 is also provided with an observation window 111 for real-time observation of the feed mixing status inside the chamber.
[0021] The upper cover 12 is sealed to the mixing chamber housing 11, and an upper cover bearing 121 is mounted on it to support one end of the mixing shaft 13. A mixing shaft bearing seat 134 is fixed on the frame 2, and a mixing shaft bearing 135 is installed in the seat. The two ends of the mixing shaft 13 are rotatably assembled through the upper cover bearing 121 and the mixing shaft bearing 135 respectively to ensure the stable operation of the mixing shaft 13.
[0022] The mixing shaft 13 is installed through the mixing chamber shell 11 and is located on the auger structure inside the connecting section 113. The first feeding blade 131 and the second feeding blade 132 are symmetrically fixed thereon (both blades are hollowed out in the middle to reduce feed adhesion and improve mixing uniformity). The mixing shaft 13 is installed through one end of the mixing shaft bearing seat 134 and is coaxially fitted with the driven drive wheel 133 and the hopper drive wheel 1331, which rotate synchronously with the mixing shaft 13.
[0023] The drive assembly 4 provides power to the mixing shaft 13 and includes a motor 41 fixed to one side of the frame 2. The output end of the motor 41 is equipped with a drive wheel 412. The drive wheel 412 and the driven wheel 133 on the mixing shaft 13 are driven by a belt (or chain). After the motor 41 is started, it can drive the drive wheel 412, the driven wheel 133 and the mixing shaft 13 to rotate in sequence to realize the stirring action.
[0024] The first hopper 315 is fixedly supported by the support 21. The first hopper 315 is used to store and transport the first type of feed. Its top is provided with an air inlet 3154 and an air outlet 3155 (to balance the air pressure inside and outside the hopper and prevent feed blockage). The bottom is fixed with a first hopper bearing seat 3151. The first hopper bearing 3152 is installed in the seat. The first hopper bearing seat 3151 cooperates with the rotating shaft to install a first hopper driven wheel 3153 (used to drive the feeding component inside the hopper).
[0025] The second hopper 316 is adapted to the structure of the first hopper 315 and is used to store and transport the second type of feed. The bottom of the hopper is fixed with a second hopper bearing seat 3161, and a second hopper bearing 3162 is installed inside the seat. The second hopper driven wheel 3163 is installed through the second hopper bearing seat 3161 cooperating with the rotating shaft.
[0026] It should be noted that the first hopper driven wheel 3153 and the second hopper driven wheel 3163 are simultaneously linked with the hopper driving wheel 1331 on the mixing shaft 13 (through belt or gear). The hopper driving wheel 1331 and the transmission driven wheel 133 are coaxially arranged and can rotate synchronously with the mixing shaft 13, thereby synchronously driving the feeding components of the two hoppers to achieve synchronous and quantitative feeding of the two feeds.
[0027] This utility model uses power transmission as its core and achieves integrated operation of "material mixing-automatic discharging" through the collaboration of multiple components. After the stirring motor 41 starts, it transmits power stably to the mixing shaft 13 through transmission mechanisms such as belt drive and gear drive, driving the mixing shaft 13 to rotate at a uniform speed, providing the power foundation for subsequent mixing and discharging processes. Example
[0028] like Figure 3 , Figure 4As shown, based on Embodiment 1, the feed mixer is further provided with a lifting mechanism 3 on the discharge port 14 of the feed cylinder. The lifting mechanism 3 includes a cylindrical elevator housing 31 with a feed inlet 312, a pressure cap 33 fitted on the top of the elevator housing 31, a top bearing 331 fitted in the pressure cap 33, an elevator bearing seat 35 fixed to the bottom of the elevator housing 31, a bottom bearing 351 fitted in the elevator bearing seat 35, and an auger 32 fitted at both ends by the top bearing 331 and the bottom bearing 351 respectively. The lifting driven wheel 36 is rotatably mounted at the bottom of the hinge part 37 through the first bearing seat 34. The first bearing seat 34 is fitted with a first bearing 341. The bottom of the central shaft of the auger 32 is located outside the elevator housing 31 and fits with the hinge part 37. The feed inlet 312 fits with the discharge port 14 of the feed cylinder. The mixing shaft 13 fits with the lifting driven wheel 36 through a belt. To ensure safer and more stable operation of the transmission mechanism, the drive wheel 412, the driven transmission wheel 133, the driven mixing shaft wheel 136, and the lifting driven wheel 36 are all installed inside a protective cover 411. The auger 32 can be tilted at any angle through the hinge 37, and the hinge 37 and the auger 32 are driven to rotate synchronously by the rotation of the lifting driven wheel 36.
[0029] The mixing shaft 13 extends into the enclosed mixing chamber shell 11, and the first feeding blade 131 mounted on the mixing shaft 13 rotates synchronously. When various feeds to be mixed are put into the mixing chamber shell 11, the first feeding blade 131 lifts, diffuses, and shears the materials through rotation, breaking the agglomeration of the materials, so that the different feed components can be fully homogenized and mixed in the mixing chamber shell 11, and finally achieve the preset mixing uniformity requirements.
[0030] After the materials are mixed, the discharge lifting auger 32, which is linked to the mixing shaft 13 of the mixer, starts synchronously with the mixing shaft 13. The discharge lifting auger 32 is a screw conveyor structure. When its screw blades rotate with the main shaft, they generate axial thrust on the finished feed in the elevator housing 31, pushing the material smoothly upward from the discharge port at the bottom of the mixing chamber housing 11 along the auger conveyor channel. Finally, the material is transferred to the designated receiving device such as the storage silo or conveyor belt (not shown in the figure) above, completing the fully automated operation of the "mixing-discharging" process.
