Description

Technical Field

[0001] The invention 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 the field of industrial production. A Chinese patent published as "CN111330507A" discloses a high-efficiency mixer, which includes a material rack (a material silo positioning rack) for mounting a silo. The silo is pressed by an oil cylinder or a gas cylinder on the material rack. The material rack is driven to rotate by a positioning rack driving device, thereby driving the silo to rotate to achieve mixing of materials.

[0003] This type of silo mixer only drives the silo to rotate through the rack and positioning rack drive device to mix the materials. This is good for mixing ordinary materials, but when mixing materials with high viscosity or high hardness, the materials are difficult to mix evenly, resulting in poor mixing effect. For this reason, the materials need to be cut and stirred before mixing, and then mixed, so as to meet the quality requirements of the mixture.

[0004] In existing stirring devices, such as stirring kettles, the stirring shaft is driven to rotate by a stirring motor, thereby stirring the materials in the silo. The body of the stirring motor is generally fixedly arranged at the top or bottom of the stirring kettle. When using this stirring device with a fixed stirring shaft and stirring motor, the material needs to be input into the stirring kettle through an input device, which not only increases the process flow of material input, but also easily causes contamination when different batches of materials are mixed. In addition, the installation and disassembly of the stirring shaft is also inconvenient. When the stirring shaft needs to be cleaned, maintained or replaced, the operator needs to stop the mixer for operation, thereby reducing the efficiency of feeding 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 present invention provides a mobile silo mixer with a stirring function and a stirring shaft that is easy to install, disassemble and maintain, and has high feeding and mixing efficiency and good mixing effect.

[0007] The mobile silo mixer of the present invention comprises a main frame, a material frame arranged on the main frame, and a material frame driving device for driving the material frame to rotate. The material frame 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 arranged on the top plate. The adjustable motor assembly comprises a motor, the body of the motor is arranged on the top plate, and a docking seat is arranged on the output shaft of the motor; The flying knife assembly includes a stirring shaft, a docking joint that can be disengaged from the docking seat is provided on the stirring shaft, a sealing plate and a plurality of stirring blades are provided on the stirring shaft, 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.

[0008] The advantage of the mobile silo mixer is that an adjustable motor assembly is provided on the top plate of the material rack, and also includes a flying knife assembly. The adjustable motor assembly includes a motor whose body is provided on the top plate of the material rack, and the output shaft of the motor is detachably connected to the docking joint on the top of the stirring shaft through a docking seat. The flying knife assembly is detachably provided at the feed inlet on the top of the silo through a sealing plate on the stirring shaft. In this way, the mobile silo mixer can drive the silo and the flying knife assembly thereon to rise and fall through the silo lifting device on the material rack, and realize the rapid clutch of the flying knife assembly and the output end of the motor through the docking seat and the docking joint.

[0009] Since the output end of the stirring shaft motor can be set in clutch rather than fixed design, the operator can pre-install another flying knife assembly at the feeding port of the next silo while the mixer is mixing materials in a silo. When the silo is mixed, the operator can quickly load the silo pre-installed with the flying knife assembly onto the material rack of the mixer, and quickly dock the motor and the flying knife assembly through the silo lifting device, docking seat and docking head, so as to stir and mix the materials in the silo.

[0010] Compared with the existing mixer without a stirring device, the mobile silo mixer can cut and stir materials with high viscosity or hardness, and then mix the materials through the material rack driving device.

[0011] Compared with conventional stirring devices such as stirring kettles, the mobile silo mixer does not need to transfer materials from the silo to the stirring kettle, thereby reducing the process of material transfer. Instead, an independent flying knife assembly is set at the feed port of each silo, and a docking device formed by a docking seat and a docking head is used to achieve rapid clutch with the motor. Therefore, there is no risk of cross contamination between materials in each silo. At the same time, the flying knife assembly can be set independently, and it is very convenient to install and disassemble. When the operator cleans, replaces or maintains it, there is no need to stop the mixer, thereby improving work efficiency.

[0012] Furthermore, in the mobile silo mixer of the present invention, the adjustable motor assembly also includes a base, which is fixedly mounted 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 fixedly mounted 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.

[0013] The setting of the inflatable airbag and the motor mounting plate allows the operator to easily adjust the position of the motor mounting plate in the working chamber through the motor mounting plate, thereby adjusting the position of the motor to adapt it to the corresponding type of silo. At the same time, after the position is adjusted, the operator can quickly press the motor mounting plate against the inner wall of the working chamber through the inflatable airbag, thereby quickly adjusting and fixing the position of the motor. Compared with the original motor assembly that is fastened to several fixed positions by bolt connection, the adjustable motor assembly can adjust the motor body to any position within a certain range and fix it by the inflatable airbag. The motor adjustment and fixation method is relatively simple and convenient to operate.

[0014] 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.

[0015] The setting of the transmission hole facilitates the installation of the motor mounting plate by the operator. Specifically, the operator can pass the motor mounting plate through the transmission hole and extend it into the working chamber, and then rotate it at a certain angle so that it is staggered with the transmission hole at a certain angle so that the inflatable airbag can press it against the inner wall of the working chamber.

[0016] The inflatable airbag is arranged below 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.

[0017] 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 fixedly provided 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, a plurality of second limit rods are provided on the side of the motor mounting plate, and the top ends of the second limit rods are fixedly provided on the top wall of the base.

[0018] The provision of the first limiting rod realizes the vertical limiting and supporting functions for 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.

[0019] The provision of the second limiting rod realizes the limiting of the rotation of the motor mounting plate.

[0020] 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 blowing holes penetrating the sealing plate.

[0021] The setting of the circular sealing plate realizes the adaptation of the sealing plate to the circular feeding port of the silo, and the setting of the blowing hole enables the flying knife assembly of the mixer silo to input a high-pressure air source into the silo through the blowing hole to improve the material crushing efficiency and effect.

[0022] Furthermore, in the mobile silo mixer of the present invention, a first shaft connecting 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 connecting 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.

[0023] The arrangement of the stopper column, the driving block and other components realizes the rapid clutching of the docking seat and the docking head.

[0024] 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 and is adapted to the guide column and can be lifted and lowered along the guide column, 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.

[0025] The arrangement of the guide post and the sliding seat enables the blocking post on the sliding seat to move along the axial direction of the guide post, thereby adjusting the height of the blocking post so that it can dock with the second shaft top docking joint at different heights. At the same time, this arrangement enables the blocking post to rise along the guide post when the driving block is lifted, thereby avoiding collision and damage between the blocking post and the driving block.

[0026] 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.

[0027] 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.

[0028] The setting of the spring enables the sliding seat and its upper stop column to quickly reset axially after being separated from the driving block, so that the bottom end of the stop column can be quickly inserted between adjacent driving blocks to achieve docking.

[0029] 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 locating 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.

[0030] 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.

DETAILED DESCRIPTION

[0054] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0055] Example 1: See Figures 1 to 20 The mobile silo mixer of this embodiment includes a main frame 1, a material frame 2 arranged on the main frame, and 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; The adjustable motor assembly comprises a motor 8, the body of the motor is arranged on the top plate, and a docking seat 9 is arranged on the output shaft of the motor; The flying knife assembly includes a stirring shaft 10, on which is provided a docking joint 11 which can be disengaged from the docking seat, a sealing plate 12 and a plurality of stirring blades 13, 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.

[0056] The advantage of the mobile silo mixer is that an adjustable motor assembly is provided on the top plate of the material rack, and also includes a flying knife assembly. The adjustable motor assembly includes a motor whose body is provided on the top plate of the material rack, and the output shaft of the motor is detachably connected to the docking joint on the top of the stirring shaft through a docking seat. The flying knife assembly is detachably provided at the feed inlet on the top of the silo through a sealing plate on the stirring shaft. In this way, the mobile silo mixer can drive the silo and the flying knife assembly thereon to rise and fall through the silo lifting device on the material rack, and realize the rapid clutch of the flying knife assembly and the output end of the motor through the docking seat and the docking joint.

[0057] Since the stirring shaft and the motor output end can be set in a clutch rather than a fixed design, the operator can pre-install another flying knife assembly at the feed inlet of the next silo while the mixer is mixing materials in a silo. When the silo is mixed, the operator can quickly load the silo pre-installed with the flying knife assembly onto the material rack of the mixer, and quickly dock the motor and the flying knife assembly through the silo lifting device, docking seat and docking head, so as to stir and mix the materials in the silo.

[0058] Compared with the existing mixer without a stirring device, the mobile silo mixer can cut and stir materials with high viscosity or hardness, and then mix the materials through the rack driving device.

[0059] Compared with conventional stirring devices such as stirring kettles, the mobile silo mixer does not need to transfer materials from the silo to the stirring kettle, thereby reducing the process of material transfer. Instead, an independent flying knife assembly is set at the feed port of each silo, and a docking device formed by a docking seat and a docking head is used to achieve rapid clutch with the motor. Therefore, there is no risk of cross contamination between materials in each silo. At the same time, the flying knife assembly can be set independently, and it is very convenient to install and disassemble. When the operator cleans, replaces or maintains it, there is no need to stop the mixer, thereby improving work efficiency.

[0060] 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 so as 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 a reducer, a transmission device and other components, thereby driving the connecting plate and the entire rack to rotate.

[0061] The material rack is used to carry the silo, and then drives the silo to rotate under the drive of the material rack driving device to mix the materials in the silo. It includes a connecting plate connected to the output end of the material rack driving 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 driving device such as a cylinder, an oil cylinder, and an electric cylinder. In this embodiment, the silo lifting device includes oil cylinders 16 respectively arranged 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 to form a top plate or bottom plate of a frame-shaped structure.

[0062] 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.

[0063] An oil valve connecting the left and right oil cylinders is arranged 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 can be 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.

[0064] The adjustable motor assembly is used to drive the stirring shaft of the flying knife assembly to rotate, thereby cutting and stirring the materials in the silo. Its body is set on the top plate of the material rack, and it can be fixed on the top plate of the material rack or detachably set on the top plate of the material rack, so that the operator can adjust its position and dock with silos of different models.

[0065] 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 plurality of stop posts 18 on the docking seat and providing a driving block 19 corresponding to the stop posts on the docking head. After docking, the stop posts and the driving blocks are spaced apart, and there is a certain gap between the stop posts 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 repeated here.

[0066] 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.

[0067] The several stirring blades on the stirring shaft are used to stir the materials. The docking joint at the top of the stirring shaft is used to achieve the clutch with the motor output shaft. The sealing plate in the middle of the stirring shaft is used to achieve the connection and sealing with the silo. The outer tube in the middle of the sealing plate is used to install the stirring shaft and bearings and other components.

[0068] 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 at 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 suck the sealing plate tightly to the feed port through a magnetic suction device. For example, a magnet or electromagnet can be set on the silo to tightly adsorb the iron sealing plate to 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 on the ring buckle on the sealing plate through the connecting hooks on both sides. Its specific structure will not be repeated here.

[0069] The outer tube in the middle of the sealing plate is used to install the stirring shaft, bearings and other components, and to protect the internal components. An inner tube 21 is arranged on the top, bearings are arranged at both ends of the inner tube, and a top cover 22 connected to the outer tube is arranged on the top of the inner tube. A connecting sleeve 23 connected to the stirring shaft is arranged above the top cover, and a fine-tuning screw 24 is arranged on the connecting sleeve. The end of the fine-tuning screw passes through the connecting sleeve and contacts with the stirring shaft.

[0070] 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.

[0071] 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 in the outer tube body.

[0072] The connection sleeve and the fine-adjustment screw thereon realize the fine-adjustment function of the stirring shaft so that it can be concentric with the bearing and other components.

[0073] 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, the outer tube body and other components.

[0074] In order to improve the mixing efficiency and mixing effect of the material, the surface of the sealing plate is provided with a blowing hole 26 penetrating the sealing plate, and the blowing hole can be connected to an external air source through an air inlet connector and a pipeline. The setting of the blowing hole enables the external high-pressure air source to enter the silo through the pipeline, the air inlet connector, and the blowing hole when the stirring blade cuts the stirring material, so as to blow the sheared material in the silo, so that the material can be stirred into powder as quickly as possible, thereby improving the efficiency and effect of mixing.

[0075] The following is the specific working process of the mobile silo mixer.

[0076] First, the operator pre-installs the flying knife assembly at the feed port of the silo and fixes it to the silo through a clamp. Then, the operator can load the silo with the flying knife assembly installed to a predetermined position on the bottom plate of the rack by a forklift.

[0077] When the silo is installed at the predetermined position of the bottom plate of the rack, the operator starts the oil cylinder to drive the bottom plate to rise until the silo on the bottom plate rises to the predetermined height. At this time, the silo is pressed between the top plate and the bottom plate of the rack, the sealing plate is pressed against the feed port of the silo, and the joint and the docking seat are just docked. The operator can start the motor on the top plate of the rack, and the motor output shaft drives the stirring shaft to rotate through the docking seat and the joint. As the stirring shaft rotates, the stirring blades on the stirring shaft cut and stir the materials in the silo. During the stirring process or after the stirring is completed, the rack drive device in the main body is started, and its output shaft drives the rack and the silo on the rack to rotate as a whole through the connecting plate to mix the materials in the silo until the materials are completely mixed. After that, all components are reset to wait for the next mixing.

[0078] 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, the inflatable airbag is located between the motor mounting plate and the inner wall of the working chamber, and an output hole 30 is provided on the bottom wall of the base.

[0079] Since the positions of the feed ports of various types of silos are different, during 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, this requires that the position of the motor body has a certain degree of floating, so as 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 dock. 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 a number of 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 a number of fixed positions, which cannot meet the above requirements.

[0080] The setting of the inflatable airbag and the motor mounting plate allows the operator to easily adjust the position of the motor mounting plate in the working chamber through the motor mounting plate, thereby adjusting the position of the motor to adapt it to the corresponding type of silo. At the same time, after the position is adjusted, the operator can quickly press the motor mounting plate against the inner wall of the working chamber through the inflatable airbag, thereby quickly adjusting and fixing the position of the motor. Compared with the original motor assembly that is fastened to several fixed positions by bolt connection, the adjustable motor assembly can adjust the motor body to any position within a certain range and fix it by the inflatable airbag. The motor adjustment and fixation method is relatively simple and convenient to operate.

[0081] The base and working chamber are used to install the motor and the motor mounting plate and other components. The motor mounting plate is used to fix the motor body. The inflatable airbag is used to press the motor mounting plate against the inner wall of the working chamber or loosen it from the inner wall of the working chamber, so that the operator can adjust and fix the motor position through the motor mounting plate. The output hole on the surface of the base is used to connect the motor with external stirring shafts and other components.

[0082] The base can be formed in one piece, or assembled by components such as plates, profiles, etc.

[0083] In this embodiment, the base is in a flat rectangular shape as a whole, and includes square tubes 31 on left and right sides. Two base plates 32 are arranged in parallel between the two square tubes, and two ends of the base plates are respectively fixedly connected to the square tubes on both sides.

[0084] In order to improve the strength of the base, connecting plates 33 fixedly connected to the two base plates may be respectively provided on the front and rear sides of the base plate.

[0085] In order to facilitate the 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.

[0086] The connecting seat is L-shaped as a whole, and a rib plate is connected to the L-shaped connecting seat to improve the overall strength of the connecting seat.

[0087] 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.

[0088] The motor mounting plate may be a polygonal plate. In the present embodiment, the motor mounting plate is in the shape of a triangle as a whole, wherein three corners of the motor mounting plate are partially cut off.

[0089] In order to facilitate the installation of the motor mounting plate, the upper surface of the base plate, i.e., the base, is provided with a transmission hole 35 penetrating the top wall of the base. The transmission hole can be adapted to the shape of the motor mounting plate so that the motor mounting plate passes through the transmission hole and enters the working cavity. After entering the working cavity, the motor mounting plate can be rotated at a certain angle so as to be offset from the transmission hole so that the inflatable airbag can press it against the inner wall of the working cavity. When the motor is installed, its bottom end passes through the transmission hole and is fixed to the motor mounting plate.

[0090] The transmission hole may 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 may be directly arranged in the working chamber.

[0091] 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.

[0092] The inflatable airbag can be a single annular inflatable bag, or include multiple smaller inflatable bags. For example, three inflatable bags are arranged between the motor mounting plate and the bottom wall of the base. The inflatable bags are inflated or deflated through pipes and external air pumps, thereby fastening the motor mounting plate to the base.

[0093] In order to facilitate the operator to adjust the motor, preferably, the inflatable airbag is arranged between the motor mounting plate and the bottom wall of the base. In order to limit the motor mounting plate, a plurality of first limiting rods 36 are arranged on the bottom surface of the working chamber. The bottom end of the first limiting rod is fixed on the bottom wall of the base. When the inflatable airbag is deflated, the top end of the first limiting rod contacts the motor mounting plate, thereby supporting the motor mounting plate and the motor body. At this time, there is a small gap between the motor mounting plate and the top wall of the base, and the operator can manually adjust the position of the motor mounting plate. When the inflatable airbag is inflated and the motor mounting plate is pressed against the top surface of the working chamber, the first limiting rod is separated from the motor mounting plate and spaced a certain distance apart.

[0094] 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 second limit rods, 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.

[0095] In order to buffer the impact between the motor mounting plate and the base and the noise generated during the impact, a plurality of buffer pads 38 can be provided on the surface of the motor mounting plate. In this embodiment, buffer pads matching the shape of the motor mounting plate are respectively provided at the three corners of the motor mounting plate, thereby achieving effective buffering of the motor mounting plate and reducing the noise generated when the motor is fixed.

[0096] 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 at the output hole of the base. The inner cavity of the protective tube is connected with 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.

[0098] The setting of the transmission hole facilitates the installation of the motor mounting plate by the operator. Specifically, the operator can pass the motor mounting plate through the transmission hole and extend it into the working chamber, and then rotate it at a certain angle so that it is staggered with the transmission hole at a certain angle so that the inflatable airbag can press it against the inner wall of the working chamber.

[0099] The inflatable airbag is arranged below 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.

[0100] 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.

[0101] The provision of the first limiting rod realizes the vertical limiting and supporting functions for 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.

[0102] The provision of the second limiting rod realizes the limiting of the rotation of the motor mounting plate.

[0103] 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.

[0104] The setting of the circular sealing plate realizes the adaptation of the sealing plate to the circular feeding port of the silo, and the setting of the blowing hole enables the flying knife assembly of the mixer silo to input a high-pressure air source into the silo through the blowing hole to improve the material crushing efficiency and effect.

[0105] Preferably, a first axis connecting hole 41 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 axis connecting 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.

[0106] The arrangement of the stopper column, the driving block and other components realizes the rapid clutching of the docking seat and the docking head.

[0107] Specifically, the stop 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 stop column can be directly fixed on the docking seat, or slidably arranged on the docking seat along the axial direction to adapt to the docking of shafts of different heights.

[0108] In this embodiment, the docking seat is a cylindrical docking seat, and a guide column 43 is provided on the bottom surface of the docking seat. The cross section of the guide column is non-circular, and the top of the guide column is fixed to the surface of the docking seat. The above-mentioned first shaft connection hole extends from the top surface of the docking seat to the middle or bottom surface of the guide column. A sliding seat 44 that can move along the axial direction of the guide column is provided on the guide column, and the middle part of the sliding seat has a non-circular hole adapted to the guide column, so that the sliding seat can move along the axial direction and can rotate under the drive of the guide column. Preferably, the guide column can be a rectangular guide column with a rectangular cross section, and correspondingly, the non-circular hole in the middle of the sliding seat is a rectangular hole. The blocking column is fixed on the sliding seat, and the bottom end of the guide column is provided with a flange 45 located below the sliding seat.

[0109] The arrangement of the guide post and the sliding seat enables the blocking post on the sliding seat to move along the axial direction of the guide post, thereby adjusting the height of the blocking post so that it can dock with the second shaft top docking joint at different heights. At the same time, this arrangement enables the blocking post to rise along the guide post when the driving block is lifted, thereby avoiding collision and damage between the blocking post and the driving block.

[0110] 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.

[0111] When the driving block is just at the bottom of the blocking column, the blocking column will rise a certain distance along the guide column under the lifting of the driving block. When the driving block moves to a predetermined height, the blocking column rotates a certain angle driven by the driving motor. When the blocking column rotates past the driving block, the blocking column and the driving block are staggered, and the blocking column can fall between the adjacent driving blocks under the action of gravity or elastic force, thereby achieving docking between the docking seat and the docking head. After that, the blocking column continues to rotate under the drive of the motor and contacts the driving block, thereby driving the driving block and the docking head to rotate.

[0112] In order to enable the blocking column to be quickly reset or docked with the docking head, a plurality 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 the upper blocking column to be quickly axially reset 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.

[0113] 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.

[0114] Correspondingly, a spring positioning groove 48 for positioning the spring may be provided at the bottom end of the sliding seat, and the bottom end of the spring is arranged in the spring positioning groove, thereby realizing the positioning and installation of the bottom end of the spring.

[0115] 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 material. 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.

[0116] The docking joint is used to connect the second shaft and dock with the docking seat, so as to realize the rotational drive of the second shaft. The middle part thereof has a second shaft connecting hole connected to 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, so as to realize the fixation of the second shaft and the docking joint.

[0117] A plurality of drive blocks are arranged on the docking head. After docking, each drive block is located between adjacent stop columns and has a certain gap with the adjacent stop columns. Since there is a large gap between the stop columns and the drive blocks, it is more convenient for the bottom end of the stop column to extend between the drive blocks, thereby improving the efficiency of docking.

[0118] In this embodiment, the butt joint is a circular butt joint, and a sector-shaped driving block is respectively arranged on both sides of the circular butt joint. Correspondingly, two blocking columns are also arranged on the sliding seat. The two blocking columns are respectively fixed on the left and right sides of the sliding seat, and the outer side surfaces thereof are on the same cylindrical surface as the outer side surfaces of the driving blocks, and the inner side surfaces thereof are spaced a small distance from the outer peripheral surface of the circular butt joint. After butt joint, the blocking columns are exactly located between the adjacent driving blocks, and the bottom ends thereof protrude out of the bottom surface of the butt joint.

[0120] The arrangement of the guide post and the sliding seat enables the blocking post on the sliding seat to move along the axial direction of the guide post, thereby adjusting the height of the blocking post so that it can dock with the second shaft top docking joint at different heights. At the same time, this arrangement enables the blocking post to rise along the guide post when the driving block is lifted, thereby avoiding collision and damage between the blocking post and the driving block.

[0121] 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.

[0122] 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.

[0123] The setting of the spring enables the sliding seat and its upper stop column to quickly reset axially after being separated from the driving block, so that the bottom end of the stop column can be quickly inserted between adjacent driving blocks to achieve docking.

[0124] Preferably, a spring positioning 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 positioning pin, and a spring positioning 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 positioning groove.
