Description
Technical field
The utility model relates to mixer apparatus field, the especially a kind of protection of the shaft head seal for horizontal concrete mixer structure.
Background technology
Along with the develop rapidly of the industries such as building, high ferro, water power, horizontal concrete mixing plant is in full flourish, thereby the demand of horizontal concrete mixer is also increased thereupon.And along with scientific and technological progress, client is more and more higher to the requirement of horizontal concrete mixer, require to reduce the spoilage of axle sealing structure, reduce maintenance frequency, strengthen performance and the life-span of axle sealing structure, also more and more higher.Yet, for the spindle nose protection of horizontal concrete mixer, adopting steel bushing protected mode, its protection effect is undesirable and difficult in maintenance.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the problem of above-mentioned middle existence, provide a kind of protection of the shaft head seal for horizontal concrete mixer structure, it is rational in infrastructure, effectively deadens mud and protection black box, convenient for maintaining.
The utility model solves the technical scheme that its technical problem adopts: a kind of protection of the shaft head seal for horizontal concrete mixer structure, comprise be arranged on horizontal concrete mixer and one end stretch into teeter chamber shaft, for install fixing shaft installation stiffener, be arranged on shaft and black box between stiffener is installed, is arranged on the inner mixing arm being in transmission connection with shaft in teeter chamber, for the protection of fixedly guard circle, the rotation of black box, protect ring support and for the protection of mixing arm with protect the rotation guard circle of black box;
Described installation stiffener is mounted on teeter chamber's cylinder body; Described fixedly guard circle is to be fixedly mounted on and to be installed on stiffener by the first bolt;
Described rotation protection ring support is to be in transmission connection on shaft by flat key, and described rotation guard circle is to be fixedly mounted on and to be rotated on protection ring support by the second bolt; Described rotation guard circle is arranged on fixedly guard circle rear end, rotates the sidewall of guard circle and the sidewall of mixing arm and connects; Between the sidewall of described another sidewall of rotation guard circle and fixedly guard circle, form annular resistance oar passage.
As preferred scheme, the top of described rotation guard circle is concordant with the top of mixing arm.
As preferred scheme, the top of described rotation guard circle is the top higher than mixing arm.
The beneficial effects of the utility model are: a kind of protection of the shaft head seal for horizontal concrete mixer structure, utilization rotation guard circle and fixedly guard circle, rotate protection ring support and replace steel bushing protection shaft, rotation guard circle and the fixedly reserving gaps between guard circle form annular resistance oar passage capable of being and effectively deaden mud, further protect hermetically-sealed construction, rotation protection ring support hinders oar passage by annular and moves on to the position away from shaft, form effectively protection shaft, shaft can be worn, the top of rotating guard circle is higher than the top of mixing arm or concordant with the top of mixing arm, fixedly guard circle and mixing arm are spaced apart, only rotating guard circle and fixedly between guard circle, producing friction, reach the effect of effective protection mixing arm and black box, rotate guard circle and fixedly guard circle is quick detachable, can change in time, easy to maintenance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of protection of the shaft head seal for horizontal concrete mixer structural entity structural representation described in the utility model.
Accompanying drawing acceptance of the bid note is described below: 1, shaft, 2, stiffener is installed, 3, black box, 4, fixing guard circle; 41, the first bolt, 5, rotate protection ring support, 6, rotate guard circle, the 61, second bolt; 7, flat key, 8, mixing arm, 9, annular resistance oar passage.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of shaft head seal for horizontal concrete mixer protection structure as shown in Figure 1, comprise be arranged on horizontal concrete mixer and one end stretch into teeter chamber shaft 1, for install fixing shaft 1 installation stiffener 2, be arranged on shaft 1 and black box 3 between stiffener 2 is installed, is arranged on the inner mixing arm 8 being in transmission connection with shaft 1 in teeter chamber, for the protection of fixedly guard circle 4, the rotation of black box 3, protect ring support 5 and for the protection of the rotation guard circle 6 of mixing arm 8 and black box 3;
