As shown in Figure 1, working principle of the present invention is as follows:
Decelerating motor 7 drives the drive sprocket axle 2-3 rotation on feeding door frame 2, and drive sprocket axle 2-3 rotation drives thereon
Drive sprocket 2-4 rotation, drive sprocket 2-4 drives chain 6 that is mounted thereto and being connected with driven sprocket 2-6 to be passed
Dynamic, the movement of chain 6 drives 3 rise and fall of bunker lift frame, and hopper rollover stand 4 passes through shaft and sliding bearing and axle sleeve 4-5
Connection is mounted on bunker lift frame 3, after hopper 5 is mounted on hopper rollover stand 4 by two axis thereon, then stirs hopper
The spring catch pull ring 4-2-1 being stuck in 4 upper spring pin assembly 4-2 of rollover stand in spring key seat 4-2-2 shallow slot, by spring catch pull ring
4-2-1, which is rotated by 90 °, to loose one's grip, and is caught in the deep trouth of spring key seat 4-2-2, and guiding axis 4-2-4 will protrude into rollover stand material at this time
Above the installation axle of bucket, the installation axle that hopper 5 is stuck in hopper rollover stand 4 is blocked, rise with bunker lift frame 3 in hopper 5,
Decline and fixed function is played to hopper 5 when overturning with rollover stand, prevents hopper 5 from falling off in feeding process and cause personal injury thing
Therefore when bunker lift frame 3 reaches the top of feeding door frame 2 under the pulling of chain 6, hopper rollover stand 4 overturns arc plate and feeding
Roller bearing 3-3 contact on 2 upper support axis of door frame, continues to rise, hopper rollover stand 4 is turned over bunker lift frame 3
Turn arc plate drives hopper 5 to overturn under the action of roller bearing 3-3, when bunker lift frame 3 reaches 2 uppermost limit plate of feeding door frame
When (for installing III 2-1-1 of screw thread orifice plate of support axle assembly 2-9 on i.e. left and right sliding rail), hopper 5 and hopper rollover stand 4 are turned over
Going to the angle of feeding door frame 2 is 48 °, and the material in hopper 5 is poured out, and after batch turning, decelerating motor 7 is inverted, and is driven actively
Sprocket wheel 2-4 reversion, makes 6 reverse drive of chain, and bunker lift frame 3, hopper rollover stand 4 and hopper 5 is driven to drop to feeding door frame 2
Stop when charging hopper lifting frame limit plate 2-10, then material will be filled in hopper, carries out next feeding.
The electronic stock shelf fully considers human engineering when designing, and hopper terrain clearance is designed laborsaving down to artificial loading
Position reduces labor intensity；Hopper capacity is big, and feeding can go up full vehicle twice, can terminate in the first bucket material feeding
After open heating function, be reloaded into the second bucket material, the side Bian Jiare feeding greatly reduces the waiting time in work progress；?
While guaranteeing feeding reliability, structure is simple, securely and reliably, is installed on vehicle rear portion, needed for can meeting bicycle road construction, together
When the stock shelf use clean energy resource, it is environmentally friendly.The invention can meet applying for modernization maintenance bituminous pavement well
Work demand.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention within mind and principle.
