Description
(1), technical field the utility model relates to the clear husky device of a kind of concrete mixing and transporting car mixing drum rotary sealing mechanism.
(2), background technology since concrete forms by sand, cement, rubble, water and auxiliary agent, if agitator truck mixing drum employing rotary sealing mechanism just faces the cleaning problem of this rotary sealing mechanism.Prior art openly is not suitable for the rotary sealing mechanism of concrete mixing and transporting car mixing drum, correspondingly, does not disclose the Removal Technology of rotary sealing mechanism yet.
(3), utility model content the utility model aims to provide the automatic clear husky device of a kind of concrete mixing and transporting car mixing drum rotary sealing mechanism, technical problem to be solved is, by cleaning reliably, easily of sealing mechanism, solve silt in the concrete to the wear problem of sealing mechanism.
The technical scheme that the utility model adopted is as follows:
The automatic clear husky device of a kind of concrete mixing and transporting car mixing drum rotary sealing mechanism comprises mixing drum, it is characterized in that: mixing drum input and output material port is provided with that rotate, that the have the input and output material hole synchronously round end of mixing drum; Also comprise stiff end; Described round end has transition rings in a section, and described stiff end has one section outer transition rings, has formed seal chamber between interior transition rings and the outer transition rings, is provided with a heavy above band in the sealing cavity; Described seal chamber has two all near the openend on stiff end top, and one of described openend has the flushing water inlet; Driving mechanism is installed on stiff end, and driving mechanism has the driving wheel that is in transmission connection with band, and this driving mechanism is positioned at the position on stiff end top or close this top.
Comprise that also two ends have the sand surfing device of entrance and exit respectively, the inlet of sand surfing device is communicated with two of the openend of described seal chamber, and the outlet of sand surfing device is connected with sand surfing and chews, and the last lower wall of sand surfing device inlet is connected with interior transition rings with outer transition rings respectively.
Good effect of the present utility model is:
Rotate the auxiliary sediment outflow desilting technology of waterpower by band, realized that convenience carries out husky clearly, dredging operation to rotary sealing mechanism in time, improved its life-span, and improved the automaticity of washing and cleaning operation.
(4), description of drawings Fig. 1 is the structural representation of first kind of rotary sealing mechanism form of the utility model.
Fig. 2 is the structural representation of second kind of rotary sealing mechanism form of the utility model.
Fig. 3 the utility model band rotates the auxiliary sediment outflow dredging structure schematic diagram of waterpower.
(5), the specific embodiment further specifies the utility model below in conjunction with drawings and Examples.
The utility model comprises the mixing drum 1 that is used to be installed on the car body and has rotary drive mechanism, and wherein the input and output material port of mixing drum 1 is positioned at the rear end of mixing drum 1, and the rotary drive mechanism of mixing drum 1 is positioned at the front end of mixing drum 1.
Mixing drum 1 input and output material port is provided with that rotate, that the have the input and output material hole synchronously round end 3 of mixing drum 1; Also comprise the stiff end 4 of bringing discharge opening into, the input and output material hole of stiff end 4 and the input and output material hole of round end 3 communicate.
Described round end 3 has transition rings 3-1 in a section, and described stiff end 4 has one section outer transition rings 4-1, has formed seal chamber 7 between interior transition rings 3-1 and the outer transition rings 4-1, is provided with triple seal band 5 in the sealing cavity.
First kind of rotary sealing mechanism is provided with expandable under water-filling or inflated condition, as to be positioned at band 5 outsides annular pressure band 6 as shown in Figure 1 in seal chamber 7.Annular pressure band 6 after the expansion is full of the seal chamber 7 outside the band 5.
Second kind of rotary sealing mechanism as shown in Figure 2, described band 5 has water-filling or the gas-filled cavity that band 5 is expanded; Band 5 after the expansion is full of described seal chamber 7.
Described water-filling or inflation mode are: expander connects water under high pressure (gas) source by pipeline.
