Abstract
The invention relates to a stirring device capable of remotely controlling engagement and disengagement. The stirring device comprises stirring shafts and a first driving system used for driving the stirring shaft to rotate. The stirring device further comprises a standby second driving system, wherein the second driving system comprises a second driving shaft and a connecting piece arranged at the lower part of the second driving shaft in a sleeving manner; the connecting piece can be regulated up and down on the second driving shaft through a remote control mechanism; when being regulated downwards, the connecting piece can be engaged with a shaft coupling arranged at the top of each stirring shaft. When faults occur in the first driving system, the stirring device can automatically switch to the standby second driving system through remote operation, and the normal operation of the stirring device is ensured. In addition, under the condition that a stirring paddle is stuck and cannot rotate, the second driving system is inverted, so that an upper stirring shaft and a lower stirring shaft are smoothly disengaged from the stirring paddle. Thus, the convenience of equipment overhaul is improved, and quick disassembly, maintenance and replacement are realized.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, be the structural representation of the agitating device of Long-distance Control engagement provided by the invention and disengagement;
The first drive system that this agitating device comprises shaft and drives this shaft to rotate, wherein, the first drive system comprises the first stirring motor 3, this first stirring motor 3 is connected with shaft by decelerator, the lower end of shaft is provided with paddle 12, and shaft drives paddle 12 to rotate under the driving of the first stirring motor 3.
As shown in Figure 2, agitating device also comprises the second drive system for subsequent use, the second drive system comprises the second stirring motor 1 for subsequent use and the second drive unit 2 for subsequent use being connected with the second stirring motor 1, the second drive unit 2 comprises the second driving shaft 5 and is set in the connector of the second driving shaft 5 bottoms, connector by Long-distance Control mechanism can be on the second driving shaft 5 up-down adjustment, when connector regulates downwards, can be meshed with the shaft coupling that shaft top arranges, thereby the second drive systems shaft rotates.In the time that the first drive system breaks down, by Long-distance Control, shaft is connected in the second drive system for subsequent use, ensure the normal work of agitating device.
Connector can be selected sleeve 6, and sleeve 6 is fixed on the second driving shaft 5 by locking pin 4, when locking pin 4 is extracted by Long-distance Control mechanism sleeve 6 eject regulate downwards with shaft coupling be meshed, thereby the second drive system work.Wherein, described connector can be selected other attaching parts, and every parts with this function all can.
The second driving shaft 5 is multidiameter, and the diameter of multidiameter successively decreases successively under upper, and the interior shape on sleeve 6 tops and this multidiameter shape are suitable.In order to ensure that sleeve can better eject, between sleeve 6 and the second large footpath of driving shaft 5, be provided with spring 7.
Shaft coupling 8 is hexagonal shaft coupling; The shape of sleeve 6 lower inside and the shape of hexagonal shaft coupling are suitable.
Thus, when the first drive system breaks down cannot work on time, can engage with shaft by operated from a distance control the second drive system, ensure the normal operation of equipment.
Shaft comprises top shaft 10 and bottom shaft 11, and top shaft 10 is connected by the pull bar screw 9 being located in top shaft 10 with bottom shaft 11, and the head of pull bar screw 9 is fastened in shaft coupling 8.Shaft coupling 8 adopts and is threaded with the upper end of top shaft 10.
As shown in Figure 3, the top of pull bar screw 9 is square block, and the inside of shaft coupling 8 is provided with the square opening suitable with the top of pull bar screw, and the top card of pull bar screw 9 is combined in the square opening of shaft coupling 8.
Thus, even rupture etc. under extreme situation when clamping stagnation appears in paddle, top shaft and bottom shaft can be thrown off by the operated from a distance of this mechanism, thereby reduce replacing time and cost, improve the convenience of Whole Equipment maintenance.
Below two of this agitating device kinds of functions are described respectively:
Function one, in the time of needs cut-in stand-by machine operation, extract the locking pin on drive unit for subsequent use by long-range mechanism operation, sleeve completes engagement in the second driving shaft ejects and be inserted in the shaft coupling the shaft axle head of blender top, now start the second stirring motor for subsequent use and just can continue to drive shaft to rotate, thereby drive paddle to stir at blender.As shown in Figure 4, be the state diagram before sleeve engages with shaft coupling, in figure, A is the amplifier section of sleeve and shaft coupling junction; As shown in Figure 5, be the state diagram after sleeve engages with shaft coupling, in figure, B is the amplifier section of sleeve and shaft coupling junction.
Function two: shaft is divided into top shaft and bottom shaft two parts, adopts pull bar screw that two parts are fixed.Shaft coupling adopts and is threaded with shaft, now consider that shaft cannot rotate under extreme case, extract the locking pin on drive unit for subsequent use by long-range mechanism operation, sleeve ejects and is inserted in the shaft coupling the shaft axle head of blender top from drive unit the second driving shaft for subsequent use and complete engagement; Now start motor for subsequent use and rotate counterclockwise, unscrew shaft coupling, thus shaft coupling back-out from shaft top, disconnect and being connected of shaft top; Because pull bar screw top is that square block penetrates in the square opening in shaft coupling, the square opening end face dieback of pull bar screw top and shaft coupling, shaft coupling rotates counterclockwise and drives pull bar screw to rotate counterclockwise and upward sliding simultaneously, thereby pull bar screw is back-outed from shaft bottom, completed the disengagement of upper and lower part shaft.
Long-distance Control engagement of the present invention and the agitating device of throwing off are not limited to above-mentioned detailed description of the invention, and those skilled in the art's technical scheme according to the present invention draws other embodiment, belongs to equally technological innovation scope of the present invention.
