Description

Technical Field

[0001] The utility model relates to a material shearing device, in particular to a flying knife component of a mixer bin. Background Art

[0002] A mixer is a mechanical device for mixing materials inside a silo. A Chinese patent with publication number "CN212283873U" and titled "A silo for a mixer" discloses a silo for a mixer, which includes a main silo, a discharge silo located below the main silo, and an inlet silo located at the top of the main silo. A sealing valve is provided at the discharge port of the discharge silo. When working, the silo is fixed to the silo rotating frame by a clamping device such as an oil cylinder or an air cylinder, and then rotates with the silo rotating frame under the drive of the driving device in the main body of the mixer, thereby achieving the mixing operation of the materials.

[0003] In order to mix viscous or agglomerated materials, the mixer needs to shear the materials inside the main bin through a stirring device so as to stir and mix the materials. Existing stirring devices mostly use stirring blades to stir the materials, and the main shaft of the stirring blades is generally directly connected to the output end of the drive motor on the frame. For a stirring device with this structure, since the main shaft is directly connected to the motor output shaft, the operator needs to extend the stirring blades into the silo online each time stirring, and seal the stirring device and the silo before stirring, which is inconvenient to operate. At the same time, when the stirring device needs to be cleaned, the operator needs to remove the stirring blades from the output end of the drive motor and then clean it. The installation and disassembly of the stirring blades is relatively cumbersome, and the mixer needs to be stopped for cleaning. In addition, when the silo model is changed or the stirring blades are damaged, the operator also needs to stop the machine to replace the corresponding parts, thereby reducing the mixing efficiency of the materials. Summary of the invention

[0006] The advantage of the flying knife assembly of the mixer silo is that it can be quickly installed at the feed port of the mixer silo through the sealing plate and the outer tube body, and can be quickly connected and separated with the output end of the drive motor through the docking joint at the top of the stirring shaft. Compared with the existing shear stirring device in which the stirring shaft is fixed to the output end of the drive motor, it can be pre-installed on the mixer silo when the mixer is working, so that the operator can quickly load the silo through multiple sets of flying knife assemblies. At the same time, when the stirring blades need to be cleaned or maintained, the operator does not need to stop the mixer and can clean and maintain the flying knife assembly alone without affecting the normal operation of the mixer. When the flying knife assembly is damaged, the operator can directly update the corresponding parts without stopping the machine, thereby improving the equipment utilization rate of the mixer, as well as the material loading and mixing efficiency.

[0007] Furthermore, in the utility model, the flying knife assembly of the mixer silo is provided with a limiting block on the butt joint.

[0008] The setting of the limit block realizes the docking of the docking head and the docking seat at the output end of the drive motor.

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.

[0013] 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.

[0014] Furthermore, in the utility model, the flying knife assembly of the mixer silo, 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.

[0015] 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.

[0016] Furthermore, in the flying knife assembly of the mixer silo of the utility model, the sealing plate is fastened to the feed port of the silo by a clamp.

[0017] The setting of the clamp enables the operator to conveniently fasten the sealing plate to the feed port of the silo to prevent it from falling off from the feed port of the silo during transportation and mixing, and to prevent material leakage from the feed port.

DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation of the present invention 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.

[0029] Example 1: See Figures 1 to 6 The flying knife assembly of the mixer silo of this embodiment includes a stirring shaft 1, on which a plurality of stirring blades 2 are arranged. The flying knife assembly of the mixer silo also includes a sealing plate 3, in the middle of which an outer tube body 4 is arranged, the outer tube body is fixedly connected to the sealing plate, the top end of the stirring shaft passes through the outer tube body and is connected to a docking joint 5, the middle part of the docking joint is fixedly arranged at the top end of the stirring shaft, and a plurality of bearings 6 are also arranged between the stirring shaft and the outer tube body.

[0030] The advantage of the flying knife assembly of the mixer silo is that it can be quickly installed at the feed port of the mixer silo through the sealing plate and the outer tube body, and can be quickly connected and separated with the output end of the drive motor through the docking joint at the top of the stirring shaft. Compared with the existing shear stirring device in which the stirring shaft is fixed to the output end of the drive motor, it can be pre-installed on the mixer silo when the mixer is working, so that the operator can quickly load the silo through multiple sets of flying knife assemblies. At the same time, when the stirring blades need to be cleaned or maintained, the operator does not need to stop the mixer to clean and maintain the flying knife assembly alone, and it will not affect the normal operation of the mixer. When the flying knife assembly is damaged, the operator can directly replace the corresponding parts without stopping the machine, thereby improving the equipment utilization rate of the mixer, as well as the material loading and mixing efficiency.

[0032] The sealing plate is used to seal the silo 7 to prevent the material from leaking through the feed port 8 during mixing. At the same time, the sealing plate is also used to install components such as the outer tube body and the stirring shaft.

[0033] In order to fit the circular feed opening of the silo, in this embodiment, the sealing plate is a circular sealing plate, which can be made of iron material. During installation, the operator extends the bottom end of the stirring shaft and the stirring blades thereon into the silo through the feed opening at the top of the silo until the top surface of the feed opening is tightly fitted with the bottom surface of the sealing plate.

[0034] The operator can directly place the sealing plate on the feed port of the silo, and press it against the feed port through the pressing cylinder 10 on the silo rotating frame 9 to prevent material leakage. The sealing plate can also be fastened to the feed port of the silo through a clamp to further improve the reliability and sealing of its connection. In addition, the silo can also suck the sealing plate 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 its 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.

[0035] The outer tube body is used to install components such as bearings and agitator shafts, and an inner tube body 11 is arranged on the top thereof. Bearings are arranged at both ends of the inner tube body respectively.
