Description

Technical Field

[0001] The utility model relates to a material mixing device, in particular to a mobile silo mixer. Background Art

[0002] Mixers are used to mix materials and are widely used in industrial production. A Chinese patent, published as "CN111330507A," discloses a high-efficiency mixer that includes a rack (a silo positioning rack) for mounting a silo. The silo is compressed by an oil or air cylinder on the rack. The rack is driven to rotate by a positioning rack drive, which in turn drives the silo to rotate and mix the materials.

[0003] This type of silo mixer uses only the hopper and positioning frame drive mechanism to rotate the hopper and mix the materials. While this works well for general materials, it can be difficult to achieve uniform mixing when mixing materials with high viscosity or high hardness, resulting in poor mixing results. Therefore, the materials must be cut and stirred before mixing to achieve the desired mixing quality.

[0004] Existing stirring devices, such as stirring kettles, have stirring shafts driven by stirring motors to rotate, thereby stirring the materials in the silo. The stirring motor body is generally fixed to the top or bottom of the stirring kettle. When using this type of stirring device with a fixed stirring shaft and stirring motor, materials must be fed into the stirring kettle through an input device. This not only increases the material input process flow, but also easily causes contamination when mixing different batches of materials. Furthermore, the stirring shaft is inconvenient to install and disassemble. When the stirring shaft needs to be cleaned, maintained, or replaced, the operator needs to shut down the mixer, which reduces the efficiency of loading and mixing.

[0005] In order to facilitate the mixing of materials, the stirring device can be directly installed on the mixer. For this purpose, it is necessary to design a mobile silo mixer with a built-in stirring function and a stirring shaft that is easy to install and disassemble, so as to improve the material feeding and mixing efficiency and facilitate the maintenance and updating of the stirring shaft. Summary of the Invention

[0006] In order to solve the above technical problems, the utility model provides a mobile silo mixer with a stirring function, a stirring shaft that is easy to install, disassemble and maintain, high feeding and mixing efficiency and good mixing effect.

[0007] The mobile silo mixer of the utility model comprises a main frame, a material rack arranged on the main frame, a material rack driving device for driving the material rack to rotate, the material rack comprises a connecting plate, a top plate and a bottom plate located at both ends of the connecting plate, and a silo lifting device for driving the top plate and the bottom plate to move relative to each other. The mobile silo mixer also comprises a flying knife assembly, and an adjustable motor assembly is provided on the top plate.

[0008] The adjustable motor assembly includes a motor, the body of the motor is arranged on the top plate, and a docking seat is provided on the output shaft of the motor;

[0009] The flying knife assembly includes a stirring shaft, which is provided with a docking joint that can be disengaged from the docking seat, a sealing plate and a plurality of stirring blades, an outer tube body fixedly connected to the sealing plate is provided in the middle of the sealing plate, the top end of the stirring shaft passes through the outer tube body and is connected to the docking joint, and a plurality of bearings are provided between the stirring shaft and the outer tube body.

[0010] The advantages of this mobile silo mixer lie in its ability to utilize an adjustable motor assembly and a blade assembly mounted on the top plate of the material frame. The adjustable motor assembly comprises a motor mounted on the top plate, with the motor's output shaft detachably connected to a docking station and a joint at the top of the agitator shaft. The blade assembly is removably attached to the feed inlet at the top of the silo via a sealing plate on the agitator shaft. This allows the mobile silo mixer to raise and lower the silo and its blade assembly via the silo lifting mechanism on the material frame, while the docking station and joint allow for rapid engagement and disengagement of the blade assembly from the motor output.

[0011] Because the agitator shaft motor output is clutch-able rather than fixed, the operator can pre-install another blade assembly at the feed inlet of the next silo while the mixer is mixing materials in one silo. Once the materials in that silo are mixed, the operator can quickly load the silo pre-installed with the blade assembly onto the mixer's rack. Using the silo lift, docking station, and joints, the motor and blade assembly can be quickly docked to continue mixing and stirring the materials within the silo.

[0012] Compared with existing mixers without stirring devices, the mobile silo mixer can cut and stir materials with higher viscosity or hardness, and then mix them through the material rack drive device.

[0013] Compared to conventional mixing systems like agitators, this mobile silo mixer eliminates the need to transfer materials from the silo to the mixing tank, thus reducing the material transfer process. Instead, independent blade assemblies are installed at the feed inlet of each silo, and a docking mechanism formed by a docking seat and a docking joint enables rapid engagement and disengagement with the motor. Therefore, there is no risk of cross-contamination between materials in the silos. Furthermore, the blade assemblies can be independently installed and easily disassembled, allowing operators to clean, replace, or maintain them without shutting down the mixer, thereby improving work efficiency.

[0014] Furthermore, in the mobile silo mixer of the present invention, the adjustable motor assembly also includes a base, which is fixed on the top plate of the material rack, and has a working chamber inside the base, in which a motor mounting plate and an inflatable airbag are provided, the body of the motor is fixed on the motor mounting plate, the inflatable airbag is located between the motor mounting plate and the inner wall of the working chamber, and an output hole is provided on the bottom wall of the base.

[0015] The inflatable airbag and motor mounting plate allow the operator to easily adjust the position of the motor within the working chamber via the motor mounting plate, thereby adjusting the motor's position to match the corresponding silo model. Furthermore, after the position is adjusted, the operator can quickly press the motor mounting plate against the inner wall of the working chamber via the inflatable airbag, thereby quickly adjusting and securing the motor's position. Compared to conventional motor assemblies that are bolted to a number of fixed positions, this adjustable motor assembly allows the motor body to be adjusted to any position within a certain range and secured with the inflatable airbag. This makes motor adjustment and securing simpler and more convenient to operate.

[0016] Furthermore, in the mobile silo mixer of the present invention, a transmission hole penetrating the top wall of the base and having a shape adapted to the motor mounting plate is provided on the upper surface of the base, and the inflatable airbag is arranged below the motor mounting plate.

[0017] The transmission hole facilitates installation of the motor mounting plate. Specifically, the operator inserts the motor mounting plate through the transmission hole into the working chamber, then rotates it to a certain angle, offset from the transmission hole, so that the inflatable airbag can press it against the inner wall of the working chamber.

[0018] The inflatable airbag is arranged under the motor mounting plate so that the inflatable airbag can press it against the top wall of the working chamber. When the position of the motor body needs to be adjusted, the motor mounting plate is separated from the top wall of the working chamber, so that the operator can easily adjust the position of the motor mounting plate.

[0019] Furthermore, in the mobile silo mixer of the present invention, a plurality of first limit rods are provided on the bottom surface of the working chamber, the bottom ends of the first limit rods are fixed on the bottom wall of the base, the motor mounting plate is located between the top ends of the first limit rods and the top wall of the working chamber, and a plurality of second limit rods are provided on the side of the motor mounting plate, the top ends of the second limit rods are fixed on the top wall of the base.

[0020] The setting of the first limiting rod realizes the vertical limiting and supporting function of the motor mounting plate. At the same time, after the inflatable airbag is deflated, the motor mounting plate falling on the top of the first limiting rod is more convenient for manual adjustment.

[0021] The provision of the second limiting rod realizes the limitation of the rotation of the motor mounting plate.

[0022] Furthermore, in the mobile silo mixer of the present invention, the sealing plate is an iron circular sealing plate, and the surface of the sealing plate is provided with a blowing hole penetrating the sealing plate.

[0023] The setting of the circular sealing plate realizes the adaptation of the sealing plate to the circular feed port of the silo, and the setting of the blowing hole enables the flying knife assembly of the mixer silo to input high-pressure air source into the silo through the blowing hole to improve the material crushing efficiency and effect.

[0024] Furthermore, in the mobile silo mixer of the present invention, a first shaft connection hole is provided on the surface of the docking seat, a plurality of blocking columns connected to the docking seat and capable of rotating with the docking seat are provided on the docking seat, a second shaft connection hole is provided on the surface of the docking head, and a plurality of driving blocks corresponding to the blocking columns are also provided on the docking head. After docking, each driving block is located between adjacent blocking columns and has a gap between the adjacent blocking columns.

[0025] The arrangement of the retaining column, the driving block and other components enables the rapid engagement and disengagement of the docking seat and the docking head.

[0026] Furthermore, in the mobile silo mixer of the present invention, a guide column with a non-circular cross-section is provided on the bottom surface of the docking seat, a sliding seat is provided on the guide column that is adapted to the guide column and can be raised and lowered along the guide column, and a flange is provided at the bottom end of the guide column below the sliding seat, and the blocking column is fixed on the sliding seat.

[0027] The arrangement of the guide post and the sliding seat allows the retaining post on the sliding seat to move axially along the guide post, thereby adjusting the height of the retaining post so that it can mate with the second shaft's top end joint at different heights. Furthermore, this arrangement allows the retaining post to rise along the guide post when the drive block is lifted, thereby preventing damage from collision between the retaining post and the drive block.

[0028] The flange at the bottom end of the guide post is used to limit the sliding seat to prevent it from falling off the guide post.

[0029] Furthermore, in the mobile silo mixer of the present invention, a plurality of springs are provided between the docking seat and the sliding seat, one end of the spring is connected to the docking seat, and the other end is connected to the sliding seat.

[0030] The setting of the spring enables the sliding seat and its upper stop column to quickly reset axially after separation from the drive block, so that the bottom end of the stop column can be quickly inserted between adjacent drive blocks to achieve docking.

[0031] Furthermore, in the mobile silo mixer of the present invention, a spring locating pin for installing a spring is provided on the surface of the docking seat, the top end of the spring is sleeved on the spring locating pin, and a spring locating groove for positioning the spring is provided at the bottom end of the sliding seat, and the bottom end of the spring is arranged in the spring locating groove.

DETAILED DESCRIPTION

[0056] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0057] Example 1: See Figures 1 to 20 The mobile silo mixer of this embodiment includes a main frame 1, a material frame 2 provided on the main frame, a material frame driving device (not shown in the figure) for driving the material frame to rotate, the material frame includes a connecting plate 3, a top plate 4 and a bottom plate 5 located at both ends of the connecting plate, and a silo lifting device for driving the top plate and the bottom plate to move relative to each other. The mobile silo mixer also includes a flying knife assembly 6, and an adjustable motor assembly 7 is provided on the top plate.

[0058] The adjustable motor assembly includes a motor 8, the body of the motor is arranged on the top plate, and a docking seat 9 is provided on the output shaft of the motor;

[0059] The flying knife assembly includes a stirring shaft 10, which is provided with a docking joint 11 that can be disengaged from the docking seat, a sealing plate 12 and a plurality of stirring blades 13, and an outer tube body 14 fixedly connected to the sealing plate is provided in the middle of the sealing plate. The top end of the stirring shaft passes through the outer tube body and is connected to the docking joint, and a plurality of bearings 15 are provided between the stirring shaft and the outer tube body.

[0060] The advantages of this mobile silo mixer lie in its ability to utilize an adjustable motor assembly and a blade assembly mounted on the top plate of the material frame. The adjustable motor assembly comprises a motor mounted on the top plate, with the motor's output shaft detachably connected to a docking station and a joint at the top of the agitator shaft. The blade assembly is removably attached to the feed inlet at the top of the silo via a sealing plate on the agitator shaft. This allows the mobile silo mixer to raise and lower the silo and its blade assembly via the silo lifting mechanism on the material frame, while the docking station and joint allow for rapid engagement and disengagement of the blade assembly from the motor output.

[0061] Because the agitator shaft and motor output are clutch-able rather than fixed, the operator can pre-install another blade assembly at the feed inlet of the next silo while the mixer is mixing materials in one silo. Once the materials in that silo are mixed, the operator can quickly load the silo pre-installed with the blade assembly onto the mixer's rack. Using the silo lift, docking station, and joints, the motor and blade assembly can be quickly docked to continue mixing and stirring the materials in the silo.

[0062] Compared with existing mixers without stirring devices, the mobile silo mixer can cut and stir materials with higher viscosity or hardness, and then mix them through the material rack drive device.

[0063] Compared to conventional mixing systems like agitators, this mobile silo mixer eliminates the need to transfer materials from the silo to the mixing tank, thus reducing the material transfer process. Instead, independent blade assemblies are installed at the feed inlet of each silo, and a docking mechanism formed by a docking seat and a docking joint enables rapid engagement and disengagement with the motor. Therefore, there is no risk of cross-contamination between materials in the silos. Furthermore, the blade assemblies can be independently installed and easily disassembled, allowing operators to clean, replace, or maintain them without shutting down the mixer, thereby improving work efficiency.

[0064] The main frame is used to install the rack drive device, rack and other components. The rack drive device is used to drive the rack to rotate to mix the materials in the silo. It can be a drive motor, whose output shaft is connected to the rotating shaft in the middle of the connecting plate through components such as a reducer and a transmission device, thereby driving the connecting plate and the entire rack to rotate.

[0065] The material rack is used to support the silo, and then drives the silo to rotate under the drive of the material rack drive device to mix the materials in the silo. It includes a connecting plate connected to the output end of the material rack drive device, and the upper and lower ends of the connecting plate are respectively provided with a top plate and a bottom plate, and also includes a silo lifting device that drives the top plate and the bottom plate to move relative to each other. The silo lifting device can be a linear displacement drive device such as a pneumatic cylinder, an oil cylinder, and an electric cylinder. In this embodiment, the silo lifting device includes oil cylinders 16 respectively provided on the left and right sides of the connecting plate, the cylinder body of the oil cylinder is fixedly connected to the connecting plate, and the piston rod of the oil cylinder is fixedly connected to the bottom plate. The above-mentioned top plate is fixedly connected to the cylinder body of the oil cylinder. The top plate and the bottom plate are both plate-shaped or frame-shaped structures. In this embodiment, the top plate and the bottom plate both include two profiles or pipes, and the two profiles or pipes are fixed by a cross bar, thereby forming a top plate or bottom plate of a frame-shaped structure.

[0066] Preferably, the surface of the bottom plate may be provided with a conical valve 17 for opening the conical bin cover at the bottom of the silo.

[0067] An oil valve connecting the left and right oil cylinders is provided inside the connecting plate. When working, the external high-pressure source drives the oil cylinder to operate through the oil valve and the corresponding pipeline, thereby driving the bottom plate and the silo on the bottom plate to rise, so that the flying knife assembly on the silo is docked with the motor output end on the top plate, and the sealing plate of the flying knife assembly is pressed tightly against the sealing port of the silo to prevent material leakage during mixing.

[0068] The adjustable motor assembly drives the agitator shaft of the fly cutter assembly, thereby cutting and agitating the material in the silo. The motor assembly is mounted on the top plate of the silo and can be fixed or detached to allow the operator to adjust its position and connect it to different silo sizes.

[0069] The docking seat provided on the motor output shaft is used to dock with the docking joint of the flying knife assembly to achieve the clutch of the motor output shaft and the stirring shaft. Specifically, a groove adapted to the docking joint can be provided on the surface of the docking seat. During docking, the docking seat is inserted into the groove to achieve docking. In addition, the clutch of the docking seat and the docking joint can be achieved by providing a number of blocking columns 18 on the docking seat and providing a driving block 19 corresponding to the blocking columns on the docking head. After docking, the blocking columns and the driving blocks are spaced apart, and there is a certain gap between the blocking columns and the adjacent driving blocks to facilitate the docking of the docking joint and the docking seat. In addition, the docking joint can also be clutched with the docking seat by means of magnetic attraction or the like, which will not be described here.

[0070] The flying knife assembly is used to cut and stir the materials in the silo to achieve shearing and stirring of sticky or hard materials so that the mixer can mix the materials later.

[0071] The several stirring blades on the stirring shaft are used to stir the material. The docking joint at the top of the stirring shaft is used to achieve clutch with the motor output shaft. The sealing plate in the middle of the stirring shaft is used to achieve connection and sealing with the silo. The outer tube in the middle of the sealing plate is used to install the stirring shaft, bearings and other components.

[0072] When installing the flying knife assembly, the operator inserts the bottom end of the stirring shaft into the interior of the silo 20 through the feed port, and places the sealing plate on the top of the feed port of the silo. The operator can fasten the sealing plate to the feed port of the silo through a clamp to further improve the reliability and sealing of its connection. In addition, the operator can also use a magnetic suction device to suck the sealing plate tightly to the feed port. For example, a magnet or electromagnet can be set on the silo to tightly adsorb the iron sealing plate on the silo. In addition, the silo can also generate a certain negative pressure in the silo body through a negative pressure device to adsorb the sealing plate to the silo, or directly hook it to the buckle on the sealing plate through the connecting hooks on both sides. Its specific structure will not be repeated here.

[0073] The outer tube in the middle of the sealing plate is used to mount components such as the agitator shaft and bearings, and also protects the various components within. An inner tube 21 is located on top of the outer tube, with bearings installed at each end. A top cover 22, connected to the outer tube, is also located at the top of the inner tube. Above this top cover is a connecting sleeve 23 connected to the agitator shaft. A fine-tuning screw 24 is installed on the connecting sleeve, and the end of the fine-tuning screw passes through the connecting sleeve and contacts the agitator shaft.

[0074] The bottom end of the outer tube body is provided with a positioning sleeve 25 fixedly connected to the outer tube body, and a bearing is provided below the positioning sleeve. The top end of the stirring shaft passes through the bottom bearing of the outer tube body, the positioning sleeve, the bottom bearing of the inner tube body, the inner tube body, the top bearing of the inner tube body, the top cover and the connecting sleeve in sequence and is fixedly connected to the docking joint.

[0075] The inner tube body realizes the positioning and installation of the bearings at both ends thereof, and the provision of the top cover realizes the purpose of fastening the bearings and the inner tube body inside the outer tube body.

[0076] The connection sleeve and the fine-tuning screw thereon realize the fine-tuning function of the stirring shaft so that it can be concentric with the bearing and other components.

[0077] The positioning sleeve at the bottom of the outer tube body realizes the positioning and installation of the stirring shaft to improve its concentricity with the inner tube body, outer tube body and other components.

[0078] To improve the mixing efficiency and effectiveness of the materials, the sealing plate is provided with a blow hole 26 that penetrates the sealing plate. The blow hole can be connected to an external air source via an air inlet connector and a pipe. The provision of the blow hole allows the external high-pressure air source to enter the silo through the pipe, air inlet connector, and blow hole while the stirring blades are cutting the mixing material, blowing the sheared material in the silo into a powder as quickly as possible, thereby improving the efficiency and effectiveness of the mixing.

[0079] The following is the specific working process of the mobile silo mixer.

[0080] First, the operator pre-installs the flying knife assembly at the feed port of the silo and secures it to the silo with a clamp. Then, the operator uses a forklift to load the silo with the flying knife assembly to the predetermined position on the bottom plate of the material rack.

[0081] Once the silo is installed in the predetermined position on the rack's base, the operator activates the hydraulic cylinder to raise the base until the silo on the base reaches the predetermined height. At this point, the silo is compressed between the rack's top and bottom plates, the sealing plate is pressed against the silo's feed port, and the docking joint is properly aligned with the docking socket. The operator then activates the motor on the rack's top plate, and the motor's output shaft drives the agitator shaft through the docking socket and the docking joint. As the agitator shaft rotates, the agitator blades on the shaft cut and stir the material in the silo. During or after the mixing process, the rack drive unit within the main unit activates, and its output shaft drives the rack and the silo on it to rotate as a whole via the connecting plate, mixing the material in the silo until it is completely mixed. Afterward, all components reset and prepare for the next mixing cycle.

[0082] Preferably, the adjustable motor assembly also includes a base 27, which is fixed on the top plate of the material rack, and has a working chamber 28 inside the base, in which a motor mounting plate 29 and an inflatable airbag (not shown in the figure) are provided. The body of the motor is fixed on the motor mounting plate, and the inflatable airbag is located between the motor mounting plate and the inner wall of the working chamber. An output hole 30 is provided on the bottom wall of the base.

[0083] Since the positions of the feed ports of various types of silos are different, when mixing, in order to ensure the feeding efficiency, the silo is loaded at a fixed position on the mixer rack. At the same time, in order to quickly dock the motor with the flying knife assembly on the silo, the position of the motor body is required to have a certain degree of floatability to adjust the position of the motor output shaft relative to the stirring shaft so that it can be coaxial with the stirring shaft and quickly docked. After docking, the motor body needs to be quickly fixed to achieve stable drive and then stir the material. The existing drive motor is fixed by bolts and other components. In order to achieve position adjustment, it is generally achieved by setting several independent mounting holes on the motor base. However, this adjustment method is not only cumbersome to install and disassemble, but also the motor position can only be adjusted at several fixed positions, which cannot meet the above requirements.

[0084] The inflatable airbag and motor mounting plate allow the operator to easily adjust the position of the motor within the working chamber via the motor mounting plate, thereby adjusting the motor's position to match the corresponding silo model. Furthermore, after the position is adjusted, the operator can quickly press the motor mounting plate against the inner wall of the working chamber via the inflatable airbag, thereby quickly adjusting and securing the motor's position. Compared to conventional motor assemblies that are bolted to a number of fixed positions, this adjustable motor assembly allows the motor body to be adjusted to any position within a certain range and secured with the inflatable airbag. This makes motor adjustment and securing simpler and more convenient to operate.

[0085] The base and working chamber are used to mount components such as the motor and motor mounting plate. The motor mounting plate secures the motor body, and the inflatable airbag is used to press the motor mounting plate against the inner wall of the working chamber or release it from the inner wall of the working chamber, allowing the operator to adjust and secure the motor position using the motor mounting plate. The output hole on the base surface is used to connect the motor to external components such as the stirring shaft.

[0086] The base can be formed in one piece, or assembled by components such as plates and profiles.

[0087] In this embodiment, the base is in the shape of a flat rectangular parallelepiped as a whole, and includes left and right square tubes 31 , with two base plates 32 arranged parallel to each other between the two square tubes, and two ends of the base plates are respectively fixedly connected to the square tubes on both sides.

[0088] In order to improve the strength of the base, connecting plates 33 fixedly connected to the two base plates can be further provided on the front and rear sides of the base plate.

[0089] In order to facilitate connection with the material rack of the mixer, the front and rear ends of the square tube are respectively provided with connecting seats 34, and the connecting seats are provided with fixing bolts for fixing the connecting seats to the material rack.

[0090] The connecting seat is L-shaped as a whole, and the L-shaped connecting seat is connected with a rib plate to improve the overall strength of the connecting seat.

[0091] The square tube, base plate and connecting plate surround and form a working cavity of the base, which is used to install components such as the motor mounting plate and the inflatable airbag.

[0092] The motor mounting plate may be a polygonal plate. In this embodiment, the motor mounting plate is in the shape of a triangle as a whole, wherein three corners of the motor mounting plate are cut off.

[0093] To facilitate installation of the motor mounting plate, a transmission hole 35 is provided on the upper surface of the base plate, extending through the top wall of the base. This hole is shaped to match the shape of the motor mounting plate, allowing the motor mounting plate to pass through the hole and into the working chamber. Once inside the working chamber, the motor mounting plate can be rotated to offset the transmission hole, allowing the inflatable airbag to press it against the inner wall of the working chamber. During installation, the motor's bottom end passes through the transmission hole and is secured to the motor mounting plate.

[0094] The transmission hole can also be arranged on the bottom wall of the base and combined with the output hole into one hole. In this case, the motor body can be directly arranged in the working cavity.

[0095] The inflatable airbag is used to press the motor mounting plate against the inner wall of the working chamber. It can be installed above the motor mounting plate or below the motor mounting plate. When it is above the motor mounting plate, the inflatable airbag presses the motor mounting plate against the bottom wall of the base after inflation. When it is below the motor mounting plate, the inflatable airbag presses the motor mounting plate against the top wall of the base after inflation.

[0096] The inflatable airbag can be a single annular inflatable airbag, or include multiple smaller inflatable airbags. For example, three inflatable airbags are arranged between the motor mounting plate and the bottom wall of the base. The inflatable airbags are inflated or deflated through pipes and external air pumps, thereby fastening the motor mounting plate to the base.

[0097] To facilitate operator adjustment of the motor, an inflatable airbag is preferably positioned between the motor mounting plate and the bottom wall of the base. To limit the position of the motor mounting plate, a plurality of first limiting rods 36 are provided on the bottom surface of the working chamber. The bottom ends of the first limiting rods are fixed to the bottom wall of the base. When the inflatable airbag is deflated, the top ends of the first limiting rods contact the motor mounting plate, thereby supporting the motor mounting plate and the motor body. At this point, a small gap is left between the motor mounting plate and the top wall of the base, allowing the operator to manually adjust the position of the motor mounting plate. When the inflatable airbag is inflated and presses the motor mounting plate against the top surface of the working chamber, the first limiting rods separate from the motor mounting plate and remain a certain distance away.

[0098] In addition, in order to limit the rotation angle of the motor mounting plate, a second limit rod 37 can be set on the side of the motor mounting plate, and the top end of the second limit rod can be fixed on the top wall of the base. There are at least two of them, and the two second limit rods can be respectively set on the left and right sides of the motor mounting plate to limit the rotation of the motor mounting plate.

[0099] To cushion the impact between the motor mounting plate and the base, and to reduce the noise generated by the impact, a plurality of cushions 38 can be provided on the surface of the motor mounting plate. In this embodiment, cushions matching the shape of the cushions are provided at the three corners of the motor mounting plate, thereby effectively cushioning the motor mounting plate and reducing the noise generated when the motor is fixed.

[0100] In order to protect the motor output shaft and other components, a protective tube 39 is provided on the base. The top of the protective tube is fixed to the output hole of the base. The inner cavity of the protective tube is connected to the output hole. The bottom end of the protective tube has an opening. An observation hole 40 is provided on the side wall of the protective tube. A proximity switch can be set at the observation hole to detect whether the stirring shaft is in place.

[0101] Preferably, a transmission hole penetrating the top wall of the base and having a shape matching that of the motor mounting plate is provided on the upper surface of the base, and the inflatable airbag is arranged below the motor mounting plate.

[0102] The transmission hole facilitates installation of the motor mounting plate. Specifically, the operator inserts the motor mounting plate through the transmission hole into the working chamber, then rotates it to a certain angle, offset from the transmission hole, so that the inflatable airbag can press it against the inner wall of the working chamber.

[0103] The inflatable airbag is arranged under the motor mounting plate so that the inflatable airbag can press it against the top wall of the working chamber. When the position of the motor body needs to be adjusted, the motor mounting plate is separated from the top wall of the working chamber, so that the operator can easily adjust the position of the motor mounting plate.

[0104] Preferably, a plurality of first limit rods are provided on the bottom surface of the working chamber, the bottom ends of the first limit rods are fixed on the bottom wall of the base, the motor mounting plate is located between the top ends of the first limit rods and the top wall of the working chamber, and a plurality of second limit rods are provided on the side of the motor mounting plate, the top ends of the second limit rods are fixed on the top wall of the base.

[0105] The setting of the first limiting rod realizes the vertical limiting and supporting function of the motor mounting plate. At the same time, after the inflatable airbag is deflated, the motor mounting plate falling on the top of the first limiting rod is more convenient for manual adjustment.

[0106] The provision of the second limiting rod realizes the limitation of the rotation of the motor mounting plate.

[0107] Preferably, the sealing plate is an iron circular sealing plate, and a surface of the sealing plate is provided with blowing holes penetrating the sealing plate.

[0108] The setting of the circular sealing plate realizes the adaptation of the sealing plate to the circular feed port of the silo, and the setting of the blowing hole enables the flying knife assembly of the mixer silo to input high-pressure air source into the silo through the blowing hole to improve the material crushing efficiency and effect.

[0109] Preferably, a first axis connection hole 41 is provided on the surface of the docking seat, and a plurality of blocking columns connected to the docking seat and capable of rotating with the docking seat are provided on the docking seat. A second axis connection hole 42 is provided on the surface of the docking head, and a plurality of driving blocks corresponding to the blocking columns are also provided on the docking head. After docking, each driving block is located between adjacent blocking columns and has a gap between the adjacent blocking columns.

[0110] The arrangement of the retaining column, the driving block and other components enables the rapid engagement and disengagement of the docking seat and the docking head.

[0111] Specifically, the blocking column can rotate with the docking seat and drive the docking head to rotate through the driving block, thereby driving the second shaft to rotate. The blocking column can be directly fixed to the docking seat or slidably arranged on the docking seat along the axial direction to adapt to the docking of shafts at different heights.

[0112] In this embodiment, the docking seat is cylindrical, with a guide post 43 provided on its bottom surface. The guide post has a non-circular cross-section, and its top end is fixed to the docking seat surface. The aforementioned first shaft connection hole extends from the top surface of the docking seat to the middle or bottom of the guide post. The guide post is provided with a sliding seat 44 that can move axially along the guide post. The middle portion of the sliding seat has a non-circular hole that adapts to the guide post, so that the sliding seat can move axially and rotate under the drive of the guide post. Preferably, the guide post can be a rectangular guide post with a rectangular cross-section, and the corresponding non-circular hole in the middle of the sliding seat is a rectangular hole. The retaining post is fixed to the sliding seat, and the bottom end of the guide post is provided with a flange 45 located below the sliding seat.

[0113] The arrangement of the guide post and the sliding seat allows the retaining post on the sliding seat to move axially along the guide post, thereby adjusting the height of the retaining post so that it can mate with the second shaft's top end joint at different heights. Furthermore, this arrangement allows the retaining post to rise along the guide post when the drive block is lifted, thereby preventing damage from collision between the retaining post and the drive block.

[0114] The flange at the bottom end of the guide post is used to limit the sliding seat to prevent it from falling off the guide post.

[0115] When the drive block is exactly at the bottom of the stop column, the stop column will rise a certain distance along the guide column under the lifting of the drive block. When the drive block reaches a predetermined height, the stop column is driven by the drive motor to rotate a certain angle. When the stop column rotates past the drive block, the stop column and the drive block are staggered. The stop column can then fall between the adjacent drive blocks under the action of gravity or elastic force, thereby achieving docking between the docking seat and the docking joint. After that, the stop column continues to rotate under the drive of the motor and comes into contact with the drive block, thereby driving the drive block and the docking joint to rotate.

[0116] In order to enable the blocking column to be quickly reset or docked with the docking head, a number of springs 46 are provided between the docking seat and the sliding seat, one end of the spring is connected to the docking seat, and the other end is connected to the sliding seat. The setting of the spring enables the sliding seat and its upper blocking column to be quickly reset axially after being separated from the driving block, so that the bottom end of the blocking column can be quickly inserted between adjacent driving blocks to achieve docking.

[0117] In order to achieve the installation and positioning of the spring, a spring positioning pin 47 for installing the spring can be provided on the surface of the docking seat, and the top end of the spring is sleeved on the spring positioning pin, thereby achieving the positioning and installation of the top end of the spring.

[0118] Correspondingly, a spring positioning groove 48 for positioning the spring can be provided at the bottom end of the sliding seat, and the bottom end of the spring is provided in the spring positioning groove, thereby achieving positioning and installation of the bottom end of the spring.

[0119] In order to reduce the impact between the sliding seat and the flange, a buffer washer 49 is provided on the outer side of the guide column and is located above the flange. The buffer washer is annular and made of an elastic material, such as rubber. It can reduce the impact between the sliding seat and the flange at the bottom end of the guide column and prevent the flange from being damaged due to excessive impact force.

[0120] The docking joint is used to connect the second shaft and dock with the docking seat, thereby realizing the rotational drive of the second shaft. The middle part of the docking joint has a second shaft connecting hole for connecting the second shaft. Here, the second shaft connecting hole is a square hole, and the top end of the second shaft is a square shaft matching the square hole, thereby realizing the fixation of the second shaft and the docking joint.

[0121] There are several driving blocks on the docking head. After docking, each driving block is located between adjacent blocking columns and there is a certain gap between the adjacent blocking columns. Since there is a large gap between the blocking columns and the driving blocks, it is more conducive to the bottom end of the blocking column to extend between the driving blocks, thereby improving the efficiency of docking.

[0122] In this embodiment, the butt joint is circular, with a sector-shaped drive block positioned on either side of the circular butt joint. Correspondingly, the sliding seat is also provided with two retaining posts, fixed to the left and right sides of the sliding seat. Their outer surfaces are flush with the outer surfaces of the drive blocks, while their inner surfaces are spaced a short distance from the outer circumference of the circular butt joint. After docking, the retaining posts are positioned precisely between adjacent drive blocks, with their bottom ends protruding from the bottom surface of the butt joint.

[0123] Preferably, a guide column with a non-circular cross-section is provided on the bottom surface of the docking seat, and a sliding seat is provided on the guide column that is adapted to the guide column and can be raised and lowered along the guide column. The bottom end of the guide column is provided with a flange located below the sliding seat, and the blocking column is fixed on the sliding seat.

[0124] The arrangement of the guide post and the sliding seat allows the retaining post on the sliding seat to move axially along the guide post, thereby adjusting the height of the retaining post so that it can mate with the second shaft's top end joint at different heights. Furthermore, this arrangement allows the retaining post to rise along the guide post when the drive block is lifted, thereby preventing damage from collision between the retaining post and the drive block.

[0125] The flange at the bottom end of the guide post is used to limit the sliding seat to prevent it from falling off the guide post.

[0126] Preferably, a plurality of springs are provided between the docking seat and the sliding seat, one end of the spring is connected to the docking seat, and the other end is connected to the sliding seat.

[0127] The setting of the spring enables the sliding seat and its upper stop column to quickly reset axially after separation from the drive block, so that the bottom end of the stop column can be quickly inserted between adjacent drive blocks to achieve docking.

[0128] Preferably, the surface of the docking seat is provided with a spring positioning pin for installing the spring, the top end of the spring is sleeved on the spring positioning pin, and the bottom end of the sliding seat is provided with a spring positioning groove for positioning the spring, and the bottom end of the spring is arranged in the spring positioning groove.

[0129] The setting of the spring locating pin realizes the positioning and installation of the top end of the spring, and the setting of the spring locating groove realizes the positioning and installation of the bottom end of the spring.

[0130] Preferably, the stirring blade is a flying knife.
