Abstract

FIELD: mining industry. SUBSTANCE: handling mixing reservoir is mounted on movable wheeled frame of concrete delivery truck and mixer. Agitation of mix components carried out as a result of mixing reservoir rotation which is achieved due to movement conveyance from movable frame wheel by means of flexible tie through overtaking and blocking couplings, is fulfilled during motion of concrete delivery truck and mixer for yield. When concrete delivery truck and mixer maneuvers in reverse movement in system of movement conveyance from wheel to mixing drum, the overtaking coupling disengages automatically and mixing reservoir stops rotating. In this case unprovided load discharge is nonexistent. The buffer of traveling frame is made folding-back which allows to drive right up to receiving bunker of concrete layer. To avoid heating of blocking coupling of concrete delivery truck its movable part is placed into oil medium. Innovation is used in underground minings of formations during strengthening of mining workings. EFFECT: enhanced efficiency. 5 dwg

Description

 The invention relates to mining and can be used in underground mining when attaching mine workings.

 A concrete mixer truck is known, including a mixing drum mounted on a suspended wheel frame with a buffer, with a loading and unloading hole and with a rotation drive in the form of an electric motor with a coupling, a gearbox kinematically connected through flexible coupling with the drum.

 The disadvantage of the above device is that when it moves there is no mixing of the components of the mixture in the tank.

 The aim of the invention is the ability to mix the components during the movement of the concrete truck and eliminate unforeseen discharge of the mixture when the movement of the concrete truck along the output in the opposite direction.

 The goal can be achieved due to the fact that the concrete mixer is equipped with a blocking and overrunning clutch, an oil bath, and the overrunning clutch is mounted on the axle of one of the frame wheels and is connected via flexible coupling with a blocking clutch installed with the possibility of interaction with the coupling, the locking clutch is made with fixed and moving parts, the last of which is placed in the oil bath, and the frame buffer is mounted with the possibility of movement along the vertical axis.

 Figure 1 shows the proposed concrete mixer, front view; in FIG. 2 is a view along arrow A in FIG. 1; in Fig.3 section BB in Fig. 1; in FIG. 4 is a view along arrow B in FIG. 1; in FIG. 5 section GG in figure 2.

 The concrete mixer truck includes a mixing drum 3 with a loading and unloading hole mounted on a movable wheel frame 1 with a buffer 2 mounted for movement along the vertical axis, an electric motor 4 with a connecting sleeve 5 and a locking sleeve consisting of a fixed 6 and a movable 7 parts, moreover, the movable 7 part is placed in the oil bath 8, the gearbox 9, connected by a flexible connection 10 with the mixing drum 3. An overrunning clutch 12 is installed on the axis of one of the wheels 11 of the frame 1, connected by a flexible connection 13 with lokirovochnoy clutch mounted to cooperate with a coupling 5.

 To unload the mixture, the buffer 2 of the frame 1 is thrown to the side, the concrete mixer truck is adjusted to the receiving hopper of the paver, the lock-up clutch and the associated overrunning clutch 12 are disconnected, the electric motor 4 of the rotation drive of the concrete mixer is connected to the general power supply and the rotation of the mixing drum 3 on mixing or unloading. At the end of the unloading, the electric motor 4 is disconnected from the starting equipment of the general-purpose power supply network, the concrete mixer truck is driven away from the paver, the buffer 2 is transferred to the transport position and the concrete truck is transported to the loading point, after which the locking clutch is engaged with the coupling 5, and the loading cycle is repeated.

 If the concrete mixer truck maneuvers in reverse, then in the motion transmission system from the wheel 11 to the mixing drum 3, the overrunning clutch 12 automatically disengages, the rotation of the mixing drum 3 is stopped, and there is no unintended unloading of the mixture.

 In order to avoid heating the lock-up clutch during operation of the concrete mixer truck, the movable part 7 of the lock-up clutch is immersed in an oil bath 8.
