Description
Technical field
The utility model relates to sanitation cart field, in particular to a kind of blower automatic safety device.
Background technique
Sanitation cart air outlet currently on the market is open type, no air outlet self closing linkage.
Open type air outlet will lead to machine in operation, and rubbish is fallen into blower, so that fan operation speed becomes
It is slow or even impaired, working efficiency is reduced, maintenance cost is provided.
Utility model content
The purpose of the utility model is to provide operational efficiency height, a kind of low blower automatic protections of plugging rate
Device.
Purpose of the utility model is realized as follows: a kind of blower automatic safety device, including Blower Housing, pressing plate group
Part, turnover panel, connecting rod, turnover panel limited block, the first linkage block, the second linkage block, the first connecting shaft, the second connecting shaft, third connection
Axis, the fourth connecting shaft；The Anchor plate kit connect axis connection, first connecting shaft and blower by first with the first linkage block
Shell is flexibly connected, and first linkage board end is connect by the second connecting shaft with connecting rod, and the connecting rod is connected by third
Axis is connect with the second linkage block, and the linkage block is hinged with turnover panel center by the fourth connecting shaft, the fourth connecting shaft with
Blower Housing is flexibly connected.
Compared with prior art, the utility model have the beneficial effect that due at air outlet be provided with drop in leaf,
So that air outlet may be implemented freely it is on and off, panel turnover mechanism can be pressed when object is fallen, so that inner fan will not
Blocking, operation is more smooth, and working efficiency is higher.
As a preferred embodiment of the present invention, turnover panel limited block is provided with below the turnover panel.
As the further preferred scheme of the utility model, the above-mentioned Blower Housing is provided with the opening slightly larger than turnover panel.
As the further preferred scheme of the utility model, the connecting rod has been provided opposite to restore turnover panel to closed state
Reset tension spring.
Detailed description of the invention
Fig. 1 is schematic diagram of internal structure when the air duct of the utility model and blower are closed.
Fig. 1-2 is the overall schematic of the utility model.
Wherein, 1 Blower Housing, 2 Anchor plate kits, 3 turnover panels, 4 connecting rods, 5 turnover panel limited blocks, 6 first linkage blocks, 7 second
Motion block, 8 first connecting shafts, 9 second connecting shafts, 10 third connecting shafts, 11 the fourth connecting shafts, 12 reset tension springs.
Specific embodiment
As shown in Figure 1, a kind of blower automatic safety device, including Blower Housing 1, Anchor plate kit 2, turnover panel 3, connecting rod 4, turn over
Plate limited block 5, the first linkage block 6, the second linkage block 7, the first connecting shaft 8, the second connecting shaft 9, third connecting shaft the 10, the 4th connect
Spindle 11；Anchor plate kit 2 is connect with the first linkage block 6 by the first connecting shaft 8, and the first connecting shaft 8 connects with 1 activity of Blower Housing
It connects, 6 end of the first linkage board is connect by the second connecting shaft 9 with connecting rod 4, and connecting rod 4 passes through third connecting shaft 10 and the second linkage
Block 7 connects, and the second linkage block 7 is hinged with 3 center of turnover panel by the fourth connecting shaft 11, the fourth connecting shaft 11 and Blower Housing 1
It is flexibly connected.
Turnover panel limited block 5 is provided with below above-mentioned turnover panel 3.
Above-mentioned Blower Housing 1 is provided with the opening slightly larger than turnover panel 3.
Above-mentioned connecting rod 4 is provided opposite to restore turnover panel 3 to the reset tension spring 13 of closed state.
The working principle of the utility model is described below: after sucking rubbish, rubbish, which pushes Anchor plate kit 2, passes through first
Motion block 6 drives connecting rod 4 and then turnover panel 3 is pulled to open turnover panel 3, the mechanisms such as automatic protection blower interior impeller, when air duct is opened
Turnover panel 3 is restored to closed state by the reset tension spring 13 on 4 opposite of connecting rod by Anchor plate kit 2.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
