Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, specifically to a high-efficiency mixing and stirring device for feed premix. Background Technology

[0002] In feed production, the uniformity of premix mixing directly affects feed quality and subsequent animal husbandry outcomes. Most commercially available premix mixing devices employ a single mixing shaft and blades. However, this traditional mixing structure has significant drawbacks: First, premixes tend to accumulate on the inner wall of the mixing drum during mixing. Since this portion of material remains stationary throughout the process, it affects the uniformity of the premix. Second, the single mixing direction and trajectory result in a limited flow path for the premix within the drum, easily creating mixing dead zones. This not only leads to low mixing efficiency but also negatively impacts the uniformity of the premix. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency mixing and stirring device for feed premixes in order to solve the above problems, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention provides a high-efficiency mixing and stirring device for feed premix, including a base and a mixing hopper body. The base is arranged horizontally, and side supports are vertically fixed on both sides of the top surface of the base. The top of the mixing hopper body is open and arranged horizontally. The mixing hopper body is located between the side supports on both sides, and a driving mixing component is combined between the mixing hopper body and the side supports to make the material on both sides of the mixing hopper body alternately and continuously gather towards the middle position and alternately and continuously move towards both sides.

[0006] The driving mixing assembly is partially combined with a material agitating component inside the mixing silo body. The material agitating component rotates together with the driving mixing assembly to agitate and lift the premixed material at the bottom of the mixing silo body.

[0007] The driving mixing component is equipped with detachable assembly components on both sides inside the mixing hopper body, and the material agitation components are detachably assembled with the driving mixing component through the detachable assembly components.

[0008] Preferably, the upper half of the mixing silo body is a rectangular silo body and the lower half is a semi-cylindrical silo body. A discharge pipe is vertically fixed and connected to the middle of the bottom of the mixing silo body, and the discharge pipe is coaxially combined with an electric valve for controlling its opening and closing.

[0009] Preferably, both sides of the bottom of the mixing hopper are fixedly connected to the top surface of the base by vertically arranged pillars.

[0010] Preferably, the top of the mixing hopper body is covered with a top cover in a vertical sliding fit, and handles are vertically fixed on both sides of the top surface of the top cover.

[0011] Preferably, the driving mixing assembly includes a drive motor and a drive shaft. The drive motor is horizontally fixed to the outside of the side support on one side, and the motor shaft of the drive motor passes through the side support in a sliding fit and is coaxially fixed to the drive shaft through a coupling. The drive shaft passes laterally through the mixing hopper body in a sliding fit, and the other end of the drive shaft is rotatably connected to the side support on the corresponding side through a bearing seat. The drive shaft has helical blades coaxially fixed on both sides of the outer periphery of the mixing hopper body, and the helical blades on both sides are symmetrically distributed about the lateral middle position of the mixing hopper body. The material actuation assembly is detachably assembled and disassembled at both ends of the drive shaft on the outer periphery of the mixing hopper body through the disassembly and assembly assembly.

[0012] Preferably, the motor shaft is coaxially rotatably connected to the bearing housing at the position where it passes through the side support, and the bearing housing is fixed to the inner end face of the side support. The drive shaft is also coaxially rotatably connected to the bearing housing at the positions where it passes through the two outer sides of the mixing hopper body, and the bearing housing is fixed to the outer end faces of both sides of the mixing hopper body.

[0013] Preferably, the drive motor is a reversible motor, and the drive shaft and the spiral blades are coaxial with the center of the lower half of the mixing hopper body.

[0014] Preferably, there are two material actuation components, located at the upper and lower periphery of the drive shaft, respectively. Each material actuation component includes a U-shaped actuation plate and a material passage hole. The U-shaped actuation plate is upside down at both ends of the drive shaft located inside the mixing hopper body. Both ends of the U-shaped actuation plate are detachably connected to the drive shaft via the disassembly and assembly assembly. The outer diameter of the outer edge of the U-shaped actuation plate is adapted to the inner diameter of the lower half of the mixing hopper body. The surface of the U-shaped actuation plate is evenly provided with multiple material passage holes.

[0015] Preferably, each of the disassembly and assembly components includes a mating seat and a fixing sleeve. The mating seats are vertically fixed at the two adjacent ends of the U-shaped material feeding plates at the upper and lower positions, and each mating seat has a longitudinally spaced limiting hole on its front end. The fixing sleeves are vertically fixed at the upper and lower ends of the outer periphery of the mixing chamber body, and each fixing sleeve has a vertically spaced mating groove. The mating grooves correspond one-to-one with the mating seats and slide vertically. The front end faces of the fixing sleeves at both sides have longitudinally spaced mounting holes, and the mounting holes are vertically connected to the corresponding mating grooves. Each mounting hole has a limiting rod inserted coaxially through it in a longitudinally sliding fit, and the rear end of each limiting rod slides longitudinally with the corresponding limiting hole. Each limiting rod has a handle fixed coaxially at its front end. The portion of the limiting rod between the corresponding handle and the front end face of the fixing sleeve is fitted with a spring in a clearance fit, and the two ends of the spring are fixedly connected to the corresponding handle and the front end face of the fixing sleeve, respectively.

[0016] Preferably, the horizontal cross-sectional shape of the mating seat and the mating groove is rectangular, the mating groove is a blind groove in the vertical direction, and the inner end of the mating seat is in close contact with the inner end of the corresponding mating groove.

[0017] In practical application, the aforementioned high-efficiency mixing and stirring device for feed premixes features a horizontally oriented mixing silo body equipped with a horizontally positioned driving mixing assembly. The driving shaft of this assembly has symmetrically distributed spiral blades coaxially fixed on both sides of the silo body. The driving shaft then drives the spiral blades on both sides to alternately rotate forward and backward at regular time intervals, allowing the material on both sides of the mixing silo body to alternately mix. The material continuously converges towards the center and alternately moves towards both sides, enriching the mixing direction and trajectory. This ensures that the premixed material has a bidirectional flow path within the mixing hopper, thereby achieving efficient and uniform mixing. Since the material agitator is combined between the two ends of the drive shaft within the mixing hopper, and the U-shaped agitator plate of the material agitator covers the outer periphery of the spiral blades, with the outer diameter of the U-shaped agitator plate matching the inner diameter of the lower half of the mixing hopper, the material is then mixed efficiently and uniformly by means of the drive shaft. The rotation of the U-shaped material-pushing plate driven by the shaft can move and lift the premixed material at the bottom of the mixing hopper, preventing it from remaining stationary. This improves the mixing efficiency and effectiveness of the premixed material. Furthermore, the material-pushing assembly can be detachably fixed to the outside of the drive shaft through the vertical sliding engagement of the mating seat and the mating groove, and the longitudinal sliding engagement of the limiting rod and the limiting hole. The design is simple and easy to implement, allowing for quick assembly of the material actuation component outside the drive shaft for premixing. Simultaneously, simply pulling the limiting rod out of the limiting hole allows the mating seat to slide vertically out of the mating groove, thus enabling the material actuation component to be detached from the drive shaft. This simple and easy-to-implement method facilitates the removal of the material actuation component from the top of the mixing chamber, making cleaning and maintenance of the material actuation component convenient.

[0018] The beneficial effects are as follows: 1. The mixing silo body of this utility model is horizontally arranged, and the mixing silo body is equipped with a flat driving mixing component. At the same time, the driving shaft of the driving mixing component is coaxially fixed with symmetrically distributed spiral blades on both sides of the outer periphery of the mixing silo body. Then, by means of the driving shaft of the driving mixing component, the spiral blades on both sides are driven to alternately rotate forward and reverse at a certain time interval. This allows the material on both sides of the mixing silo body to alternately and continuously gather towards the middle and alternately and continuously move towards both sides, enriching the mixing direction and mixing trajectory. This ensures that the premixed material has a bidirectional flow path in the mixing silo body, thereby achieving efficient and uniform mixing of the premixed material.

[0019] 2. A material agitation component is assembled between the two ends of the drive shaft inside the mixing hopper body. The U-shaped material agitation plate of the material agitation component covers the outer periphery of the spiral blade. At the same time, the outer diameter of the rotation of the outer edge of the U-shaped material agitation plate is matched with the inner diameter of the lower half of the mixing hopper body. Then, by driving the U-shaped material agitation plate to rotate through the drive shaft, the premixed material at the bottom of the mixing hopper body can be agitated and lifted, preventing the premixed material at the bottom of the mixing hopper body from being in a static state. This is conducive to further improving the mixing uniformity and effect of the premixed material.

[0020] 3. By using the vertical sliding fit between the mating seat and the mating groove of the disassembly and assembly assembly and the longitudinal sliding fit between the limiting rod and the limiting hole, the material agitator assembly can be detachably assembled and fixed on the outside of the drive shaft. The assembly method of the material agitator assembly on the outside of the drive shaft is simple and easy to implement, which facilitates the quick assembly of the material agitator assembly on the outside of the drive shaft for use in premixing material agitation.

[0021] 4. Simply pull the limiting rod out of the limiting hole to allow the mating seat to slide vertically out of the mating groove. This allows the material actuation component to be removed from the outside of the drive shaft. The method of separating the material actuation component from the outside of the drive shaft is simple and easy to achieve. This makes it easy to remove the material actuation component from the outside of the drive shaft and remove it from the top of the mixing hopper body, which is convenient for cleaning and maintenance of the material actuation component.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-7As shown, this utility model provides a high-efficiency mixing and stirring device for feed premix, including a base 5 and a mixing hopper body 2. The base 5 is horizontally arranged, and side supports 4 are vertically fixed on both sides of the top surface of the base 5. The top of the mixing hopper body 2 is open and horizontally arranged. The mixing hopper body 2 is located between the side supports 4 on both sides, and a driving mixing component 3 is combined between the mixing hopper body 2 and the side supports 4. The driving mixing component 3 is used to make the material on both sides of the mixing hopper body 2 alternately and continuously gather towards the middle position and alternately and continuously move towards both sides. Specifically, the driving mixing component 3 includes a driving motor 303 and a driving shaft 305. The driving motor 303 is horizontally fixed to the outside of the side support 4 on one side, and the motor shaft 302 of the driving motor 303 passes through the side support 4 in a sliding fit and is coaxially fixed to the driving shaft 305 through a coupling. The driving shaft 305 is in a sliding fit. The drive shaft 305 passes laterally through the mixing hopper body 2, and the other end of the drive shaft 305 is rotatably connected to the side support 4 on the corresponding side via the bearing seat 301. The drive shaft 305 has coaxially fixed spiral blades 304 on both sides of the outer periphery of the mixing hopper body 2, and the spiral blades 304 on both sides are symmetrically distributed about the middle position of the mixing hopper body 2. The drive shaft 305 has material agitation components 6 that can be detachably assembled at both ends of the outer periphery of the mixing hopper body 2 via the disassembly and assembly assembly 8. The purpose of this arrangement is to use the drive shaft 305 of the drive mixing assembly 3 to drive the spiral blades 304 on both sides to alternately turn forward and reverse at a certain time interval, so that the material on both sides of the mixing hopper body 2 can alternately and continuously gather towards the middle position and alternately and continuously move towards both sides, enriching the mixing direction and mixing trajectory, and ensuring that the premixed material has a bidirectional flow path in the mixing hopper body 2.

[0034] See Figures 1-7 As shown, a material agitator 6 is partially assembled inside the mixing hopper body 2 within the driving mixing assembly 3. This material agitator 6 is used to agitate and lift the premixed material at the bottom of the mixing hopper body 2 by rotating together with the driving mixing assembly 3. Specifically, there are two material agitator 6 components, located at the upper and lower periphery of the driving shaft 305, respectively. Each material agitator 6 includes a U-shaped agitator plate 601 and a material passage hole 602. The U-shaped agitator plate 601 is inverted and attached to the outer periphery of the driving shaft 305 within the mixing hopper body 2. Both ends of the U-shaped material feeding plate 601 are detachably connected to the drive shaft 305 via the disassembly and assembly assembly 8. The outer diameter of the outer edge of the U-shaped material feeding plate 601 is adapted to the inner diameter of the lower half of the mixing hopper body 2. The surface of the U-shaped material feeding plate 601 is evenly provided with multiple material passage holes 602. The purpose of this arrangement is to use the drive shaft 305 to drive the U-shaped material feeding plate 601 to rotate, thereby moving and lifting the premixed material at the bottom of the mixing hopper body 2, and preventing the premixed material at the bottom of the mixing hopper body 2 from being in a static state.

[0035] See Figures 1-7 As shown, the mixing drive assembly 3 is equipped with detachable assembly 8 on both sides inside the mixing hopper body 2. The material agitator 6 is detachably assembled with the mixing drive assembly 3 via the detachable assembly 8. Specifically, each detachable assembly 8 includes a mating seat 805 and a fixing sleeve 801. The mating seats 805 are vertically fixed to the adjacent ends of the U-shaped material agitator 601 at the upper and lower positions. Each mating seat 805 has a longitudinally extending limit hole 803 on its front side. The driving shaft 305 is vertically fixed to both ends of the mixing hopper body 2 at the upper and lower positions, and each fixing sleeve 801 has a vertically extending mating groove 802. The mating groove 802 corresponds one-to-one with the mating seat 805 and slides vertically. Each fixing sleeve 801 has a longitudinally extending mounting hole 806 on its front end face, which is perpendicularly connected to the corresponding mating groove 802. Each mounting hole 806 has a coaxially inserted limit rod 804 through it in a longitudinally sliding engagement. Furthermore, the rear ends of the limiting rods 804 are longitudinally slidably engaged with the corresponding limiting holes 803, and the front ends of the limiting rods 804 are coaxially fixed with handles 808. The portion of the limiting rods 804 located between the corresponding handles 808 and the front end face of the fixing sleeve 801 is coaxially fitted with springs 807 in a clearance fit manner, and the two ends of the springs 807 are respectively fixedly connected to the corresponding handles 808 and the front end face of the fixing sleeve 801. The reason for this arrangement is that by vertically sliding the mating seat 805 of the disassembly and assembly assembly 8 with the mating groove 802 and longitudinally sliding the limiting rods 804 with the limiting holes 803, the material agitator assembly 6 can be detachably assembled and fixed outside the drive shaft 305. At the same time, only by pulling the limiting rods 804 out of the limiting holes 803 can the mating seat 805 be vertically slid out of the mating groove 802, thereby detaching the material agitator assembly 6 from the outside of the drive shaft 305. The assembly and disassembly of the material agitator assembly 6 outside the drive shaft 305 is simple and easy to implement.

[0036] See Figures 1-5 As shown, the upper half of the mixing silo body 2 is a rectangular silo, and the lower half is a semi-cylindrical silo. A discharge pipe 202 is vertically fixed to the center of the bottom of the mixing silo body 2, and an electric valve 201 for controlling its opening and closing is coaxially connected to the discharge pipe 202. This arrangement allows the mixing silo body 2 to have a design that meets usage requirements, and facilitates the discharge of the uniformly mixed feed premix to the outside via the discharge pipe 202. Furthermore, the spiral blades 304 help the premix to converge towards the center, thus aiding in the discharge process through the rotation of the spiral guide blades. Optionally, both sides of the bottom of the mixing silo body 2 are fixedly connected to the top surface of the base 5 via vertically arranged support columns 7. This arrangement allows the support columns 7 to provide stable support and elevation for the mixing silo body 2.

[0037] See Figures 1-7 As shown, the top of the mixing hopper body 2 is covered with a top cover 1 in a vertical sliding fit, and handles 101 are vertically fixed on both sides of the top surface of the top cover 1 to cover the top of the mixing hopper body 2 for dust prevention. Preferably, a shock-absorbing rubber liner can be covered inside the top cover 1 to improve the stability of the top cover 1 when it is on top of the mixing hopper body 2 and reduce noise. Further optionally, the motor shaft 302 is coaxially rotatably connected to a bearing seat 301 at the position where it passes through the side support 4, and the bearing seat 301 is fixed to the inner end face of the side support 4. The drive shaft 305 is also coaxially rotatably connected to a bearing seat 301 at the positions where it passes through the two outer sides of the mixing hopper body 2, and the bearing seats 301 are fixed to the outer end faces of both sides of the mixing hopper body 2. This arrangement facilitates stable rotational support for the drive shaft 305 and the motor shaft 302 by means of the bearing seats 301.

[0038] See Figures 1-7 As shown, the drive motor 303 is a forward and reverse motor. The drive shaft 305 and the spiral blade 304 are coaxial with the center of the lower half of the mixing bin body 2. This arrangement facilitates the drive motor 303 to drive the drive shaft 305 to alternately rotate forward and reverse. It also ensures that when the drive shaft 305 drives the U-shaped material feeding plate 601 to rotate, it can perform a stable material feeding operation on the inner bottom of the mixing bin body 2. Alternatively, the horizontal cross-sectional shape of both the mating seat 805 and the mating groove 802 is rectangular, and the mating groove 802 is a blind groove in the vertical direction. The inner end of the mating seat 805 is in close contact with the inner end of the corresponding mating groove 802. This arrangement firstly facilitates a good positioning and guiding design when the mating seat 805 slides vertically along the mating groove 802. At the same time, during the process of the mating seat 805 sliding vertically along the mating groove 802, when the limiting hole 803 moves vertically with the mating seat 805 to be coaxial with the limiting rod 804, a clear indication can be given by the way that the inner end of the mating seat 805 is in close contact with the inner end of the corresponding mating groove 802.

[0039] With the above structure, in practical use, since the mixing silo body 2 is horizontally arranged and is equipped with a horizontally placed drive mixing assembly 3, and the drive shaft 305 of the drive mixing assembly 3 has symmetrically distributed spiral blades 304 coaxially fixed on both sides of the outer periphery inside the mixing silo body 2, the drive shaft 305 of the drive mixing assembly 3 drives the spiral blades 304 on both sides to alternately rotate forward and backward at a certain time interval, so that the material on both sides of the mixing silo body 2 can alternately and continuously gather and cross towards the middle position. As the material continuously moves towards both sides, it enriches the stirring direction and trajectory, ensuring that the premixed material has a bidirectional flow path within the mixing hopper body 2. This enables efficient and uniform mixing of the premixed material. Since the drive shaft 305 is equipped with material actuation components 6 at both ends within the mixing hopper body 2, and the U-shaped actuation plate 601 of the material actuation component 6 covers the outer periphery of the spiral blades 304, and the outer diameter of the U-shaped actuation plate 601 matches the inner diameter of the lower half of the mixing hopper body 2, the drive shaft 305 drives the U-shaped actuation plate 601. The 01-turnover method can agitate and lift the premixed material at the bottom of the mixing hopper body 2, preventing it from remaining stationary. This helps to further improve the mixing uniformity and effect of the premixed material. Furthermore, by using the vertical sliding engagement of the mating seat 805 and the mating groove 802 of the disassembly and assembly assembly 8, and the longitudinal sliding engagement of the limiting rod 804 and the limiting hole 803, the material agitation assembly 6 can be detachably and fixed to the outside of the drive shaft 305. The assembly method of the material agitation assembly 6 outside the drive shaft 305 is simple and easy to use. This allows for quick assembly of the material actuation component 6 onto the outside of the drive shaft 305 for premixing. Simultaneously, simply pulling the limiting rod 804 out of the limiting hole 803 allows the mating seat 805 to slide vertically out of the mating groove 802, thus enabling the material actuation component 6 to be detached from the outside of the drive shaft 305. The method of separating the material actuation component 6 from the outside of the drive shaft 305 is simple and easy to implement, facilitating its removal from the top of the mixing chamber body 2 after detachment from the drive shaft 305, and making cleaning and maintenance of the material actuation component 6 convenient.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
