Description

Technical Field

[0001] The invention relates to the technical field related to stirring and mixing equipment, and in particular to an automatic feed mixing device which is easy to clean inside. Background Art

[0002] Common feed raw materials include soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives and other feed raw materials. In the process of ingredient addition, fermentation culture and material collection and processing, many steps need to go through material mixing and stirring operations to ensure the mixing of materials during batch feed product processing and ensure the quality of the finished product.

[0003] When materials need to be mixed in the existing production process, ordinary stirring tanks and other structures are usually used for rotary stirring. For example, the feed mixer with Chinese patent publication number CN105901755B mixes feed through a high-stability compact structure, but it only performs internal stirring, and the tank body itself is left stationary. The compact structure is not easy to clean inside, and the lack of external disturbance of the material leads to uneven material stirring, which is easy to waste some materials and affect the quality of the final product. At the same time, most of the existing equipment processing only undergoes a single stirring, and additional equipment is required for operations such as material mixing and screening to ensure the fineness and uniformity of the material. The additional equipment requires additional driving equipment and more operations, which affects the processing efficiency and processing cost. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was generated.

[0004] In view of the above problems, an innovative design is carried out on the basis of the original mixing device. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic feed mixing device that is easy to clean internally, so as to solve the problems raised in the above background technology, such as uneven material mixing, lack of coordinated mixing and homogenizing treatment, and additional processing steps and processing equipment affecting processing efficiency and cost.

[0006] To achieve the above object, the present invention provides the following technical solution: an automatic feed mixing device that is easy to clean internally, comprising a mounting frame and a mixing barrel mounted inside the mounting frame;

[0007] The front and rear sides of the mounting frame are fixed brackets, and a universal shaft is arranged at the upper end of the fixed bracket, and the mixing drum forms a deflection structure with the universal shaft as a rotating shaft, and a stirring shaft is arranged inside the mixing drum;

[0008] The stirring shaft is movably arranged to penetrate the mixing barrel, and a stirring blade is arranged on the outer side of the stirring shaft. The stirring blade is an "S"-shaped structure, and the stirring blade forms a movable fitting cleaning structure with the inner wall of the mixing barrel near the mixing barrel.

[0009] The left and right sides of the mounting frame are driving brackets, and the side ends of the stirring shaft are provided with synchronous wheels;

[0010] The synchronous wheel and the stirring shaft are eccentrically arranged, and the synchronous wheel is axially symmetrically arranged on the left and right sides of the stirring shaft with the universal shaft as the axis, and the synchronous wheel forms a driving structure at the driving bracket;

[0011] A driving motor is installed on the side of the driving bracket, and the output end of the driving motor forms a reduction driving structure for the synchronous wheel through a reduction gear;

[0012] A material mixing plate is arranged below the installation frame, and a material mixing paddle is movably arranged inside the material mixing plate, and the material mixing paddle is synchronously driven with the stirring shaft.

[0013] Preferably, an eccentric hole is provided on the side surface of the synchronous wheel, and the side end of the stirring shaft is key-connected and plugged into the inner side of the eccentric hole, and the outer circumferential surface of the synchronous wheel is an arc-shaped fitting surface.

[0014] By adopting the above technical solution, the stirring shaft is driven to deflect and rotate by plugging in the eccentric hole. At the same time, the overall spherical structure can flexibly fit and roll through the arc-shaped fitting surface, which is convenient for maintaining the continuous rotation of the stirring shaft and the synchronous and flexible eccentric deflection of the mixing barrel as a whole, and helps to improve the uniformity of the mixing.

[0015] Preferably, a movable groove is provided inside the upper end of the driving bracket, and the arcuate fitting surface is movably fitted inside the movable groove, and fitting balls are evenly distributed between the movable groove and the arcuate fitting surface.

[0016] By adopting the above technical solution, the movement of the synchronous wheel is restricted to the inner side of the movable groove, and the friction is reduced by the rolling fit of the fitting ball. The fitting ball structure can also adapt to the longitudinal and lateral relative displacement components of the synchronous wheel, so as to maintain flexible rotation.

[0017] Preferably, a feed inlet is provided at the upper middle portion of the mixing cylinder, and a side discharge inlet is provided at the lower side of the mixing cylinder, and the side discharge inlets are symmetrically arranged at the left and right ends of the mixing cylinder.

[0018] By adopting the above technical solution, the mixing drum will rotate eccentrically sideways along with the stirring shaft during mixing and stirring, and will continuously tilt as a whole back and forth, resulting in a height difference between the left and right sides. Combined with the setting of the middle feed port and the side discharge port, the material enters from the middle and exits from the side end. The material is further stirred at the side end with the "S"-shaped stirring blades, ensuring a uniform mixing effect when the material is loaded and unloaded at the mixing drum.

[0019] Preferably, the mixing plate is located below the side feed outlet, and the bottom surface of the mixing plate is a filter screen, and the mixing paddle moves and stirs on the surface of the filter screen;

[0020] Below the filter screen is a lower material bin.

[0021] By adopting the above technical solution, the material mixing plate receives the material below the mixing drum for secondary mixing and at the same time cooperates with the filter screen to screen out some bulk materials or foreign matter.

[0022] Preferably, a movable drawer slot is provided on the front of the unloading bin, and a unloading tray is provided inside the movable drawer slot, and the unloading tray forms a drawer-type movable structure inside the movable drawer slot;

[0023] The unloading tray is located directly below the filter screen.

[0024] By adopting the above technical solution, the material that has been secondary sifted by the sifting plate and the filter screen falls on the unloading tray, and the material can be conveniently taken out by movably pulling out the unloading tray.

[0025] Preferably, a transmission gear ring is fixedly mounted on the outer ring of the material leveling paddle, and a driving gear is mounted inside the driving bracket, and a meshing transmission structure is formed between the transmission gear ring and the driving gear.

[0026] By adopting the above technical solution, the driving gear in the side driving bracket is used to mesh and drive the transmission gear ring, thereby driving the material mixing paddle as a whole to mix the material.

[0027] Preferably, the shaft end of the driving gear and the output end of the reducer are connected and driven via a coupling, and a synchronous transmission mechanism is used to form a synchronous transmission structure between the driving gear and the synchronous wheel, and the synchronous transmission mechanism includes a synchronous transmission belt, a transmission roller, a first bevel gear and a second bevel gear.

[0028] By adopting the above technical solution, the drive motor and the reducer installed on the drive bracket directly drive the drive gear to rotate the material leveling paddle, and at the same time, the synchronous transmission mechanism is used to synchronously link the synchronous wheel, without the need for additional drive equipment.

[0029] Preferably, the transmission roller is located below the movable groove, and a transmission structure is maintained between the transmission roller and the synchronous wheel, and a synchronous transmission belt is connected to the shaft end of the transmission roller.

[0030] By adopting the above technical solution, the transmission roller and the synchronous wheel rotate in close contact, and the synchronous wheel is driven synchronously by extending downwards through the synchronous transmission belt.

[0031] Preferably, the first bevel gear is coaxially arranged above the driving gear, and a meshing transmission structure is formed between the first bevel gear and the second bevel gear, and a synchronous transmission structure is formed between the shaft end of the second bevel gear and the shaft end of the transmission roller through a synchronous transmission belt.

[0032] By adopting the above technical solution, the downward synchronous transmission belt at the transmission roller is driven synchronously at the driving gear through the main gear transmission of the first bevel gear and the second bevel gear.

[0033] Compared with the prior art, the invention has the following beneficial effects: the automatic feed mixing device which is easy to clean internally,

[0034] A mixing drum is provided for dynamic mixing and stirring. When the materials are initially mixed through the mixing drum, the stirring shaft in the mixing drum rotates under the drive of the eccentric rotation of the synchronous wheels on both sides, and drives the mixing drum as a whole to reciprocate and tilt and swing to mix the materials. At the same time, the stirring blades at the stirring shaft are of an "S"-shaped structure corresponding to the swing of the mixing drum, that is, when the right side of the mixing drum tilts downward, the right side of the stirring blades synchronously adheres to the materials downward for stirring, so as to achieve the effect of synchronous mixing and avoid affecting the left and right displacement and overturning of the materials. The uniformity and stirring efficiency of the mixing are effectively improved by the internal stirring and external disturbance.

[0035] At the same time, the stirring blades are movably fitted on the inner wall of the mixing barrel, and the reciprocating swinging structure of the mixing barrel as a whole can effectively prevent the material from sticking inside the equipment, making it convenient for later maintenance and cleaning. When performing maintenance and cleaning inside the equipment, water can be injected into the mixing barrel, and the swinging structure of the mixing barrel drives the internal cleaning water to flush back and forth, which facilitates internal cleaning and improves the cleaning effect.

[0036] 3. A linkage-driven graded stirring and mixing mechanism is provided. In addition to the mixing cylinder for preliminary mixing at the top, an additional mixing plate is provided below the mixing cylinder for secondary mixing and screening in cooperation with the mixing cylinder for material discharge. The mixing paddle at the mixing plate plays a role in mixing and mixing the materials simultaneously, and the mixing paddle is driven in linkage with the mixing cylinder through a synchronous transmission mechanism. No additional driving equipment is required, which facilitates synchronous mixing, mixing and screening processing, effectively improves the overall uniformity and processing efficiency of the mixed materials, and reduces processing costs.
