Further, as shown in fig. 7, the front side of the shell 10 of the present embodiment is equipped with front cover 15, the bottom internal of shell is empty
Between form hopper 13, be equipped on its shell 10 for installing the side of front cover 15 and be used to support the support portion 14 of front cover 15,
Its front cover 15 is equipped with the inclined plate 16 extended to 10 side of shell, is formed between the inclined plate 16 and front cover 15 for accommodating support portion
14 holding tank 17.The structural benefit is, during installation front cover 15, it is only necessary to cover holding tank 17 on support portion 14 i.e.
Front cover 15 can be positioned, installation, fixed front cover are convenient.Meanwhile if there is feed to enter shell 10, inclined plate 16 effectively prevent feed into
Enter the gap between front cover and shell, prevents from putting material.
In the first embodiment as shown in Figure 2, if the load of plug disc chain is excessive, putty when, will be tensioned
Under the action of power, driving tensioning apparatus is run to the right, until limit on the left limit film is contacted with lead limit switch, to trigger row
The contact of degree bit switch, powers off driving motor, prevents from damaging automatic feeding system under heavy-duty service state.Work as generation
When plug disc chain chain rupture, tensile force disappears, and tensioning apparatus moves downward under the action of tension spring, until limit on the right-right-hand limit limit film and row
The contact of degree bit switch powers off driving motor, to trigger lead limit switch contact to repair chain rupture in time.
In second of embodiment as shown in Figure 3, the effect of left and right extreme position and just phase in first embodiment
Instead.The load of plug disc chain is excessive, putty when, trigger limit on the right-right-hand limit limit film；When chain rupture occurs, limit on the left limit film is triggered.Always
It, the distance caging device of above two embodiment can effectively monitor the operating status of plug disc chain, and in the event of a failure,
Effective protection automatic feeding system.
In addition, the drive assembly and hopper in the present embodiment are separately positioned, hopper is set to feeding except drive assembly automatically
In material system, feed will not generate the situation that feed is detained in the housing, makes moist or even goes bad without enclosure interior.
In the present embodiment, meshing relation is had no between the guide wheel being used cooperatively with drive sprocket and plug disc chain, is drawn
Guide wheel only serves support and guides the effect of plug disc chain, and such structure makes the relative distance between guide wheel and plug disc chain
Adjustment is more flexible, more sensitive to the variation sensing of the operating status of plug disc chain in automatic feeding system, and according to plug disk
Chain operating status makes that the flexibility accordingly adjusted is stronger, adjusting range is wider.
In short, the foregoing is merely illustrative of the preferred embodiments of the present invention, it is not intended to limit the invention, it is all in the present invention
Spirit and principle within made any modifications, equivalent replacements, and improvements etc., should be included in protection scope of the present invention it
It is interior.
