Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of clamp stable bucket tool dumping machine, including frame 1, the roller 14 being easy to carrying it is provided with bottom frame 1, the quantity of roller 14 is four, above two is fast pulley 141, and fast pulley 141 is exactly roller 14 is fixing, it is impossible to enough rotations, two next is universal wheel 142, and universal wheel 142 is that direction can rotate freely. The structure of two universal wheels 142 next can facilitate whole frame 1 in transfer process, quick turning etc.
Such as Fig. 2 or Fig. 3, frame 1 be provided with can the adjustable shelf 2 of upper and lower displacement, the both sides of adjustable shelf 2 are stuck in above frame 1, can do and move up and down freely. Two chains it are provided with between adjustable shelf 2 and frame 1, frame 1 is fixed with driving cylinder 11, drive cylinder 11 in being vertically arranged, cylinder 11 is driven to be connected with extraneous air pump, frame 1 is provided with the switch for controlling to drive cylinder 11, by switching, the piston rod of cylinder 11 is driven to move up and down. The piston rod part driving cylinder 11 is provided with fixed mount 12, drives the piston cylinder of cylinder 11 to fix with fixed mount 12, drives cylinder 11 that fixed mount 12 can be driven to move up and down. 12 two sides of fixed mount are provided with fluted disc 13 free to rotate, each fluted disc 13 and a chain engagement, cylinder 11 is driven to drive fixed mount 12 to push, owing to fluted disc 13 can rotate freely, such fluted disc 13 is structurally equivalent to the structure of movable pulley, and such fluted disc 13 moves the distance of a unit, adjustable shelf 2 just can the distance of two units, driving the pneumatic speed of cylinder 11 in cooperation, adjustable shelf 2 can quickly rise to higher position, it is possible to is rapidly performed by the work such as feeding.
Also have, the driving mechanism that adjustable shelf 2 is provided with rotary holding frame 3, drives holding frame 3 to tilt, holding frame 3 is to be fixed on adjustable shelf 2 above for that accommodate bucket tool 4 and holding frame 3 by rotating shaft, driving mechanism includes a reduction box being fixed on adjustable shelf 2 22, reduction box 22 is arranged above with manual pulley 21, driving wheel 23, manual pulley 21 drives driving wheel 23 to rotate by reduction box 22, holding frame 3 side is provided with driven pulley 31, and driven pulley 31 is all connected by chain with driving wheel 23. When needs tilt, people's rotation manual wheel 21 just can complete, then very quick and convenient, and chain has and rotates ratio accurately, the phenomenon that will not skid, not havinging bucket and have 4 problems being difficult to turn to precise angle because of skidding, and there is bigger frictional force this reduction box 22 inside, when active rotation manual pulley 21, driving wheel 23 will not rotate voluntarily.
As shown in Figure 1, holding frame 3 top is provided with the clamping clip having 4 upper edges for fixing bucket, clamping clip includes the first tong arm 321 being hinged on holding frame 3, the second tong arm 322 being fixed on holding frame 3, holding frame 3 is provided with rotatable screw mandrel 323, screw mandrel 323 runs through the first tong arm 321, and screw mandrel 323 drives the first tong arm 321 to swing by rotating. Being provided with bottom holding frame 3 and have the snap fit 331 bottom 4 for snap fit 331 barrels, snap fit 331 includes inserting the motion bar 332 of holding frame 3, being enclosed within motion bar 332 and the card that can rotate freely, and card is L-shaped, it is possible to catch on the edge bottom bucket tool 4.Being connected to the adjusting rod 333 driving card rotating on card, back-moving spring is enclosed within motion bar 332 and above and drives in motion bar 332 retraction holding frame 3, and wherein, back-moving spring bathroom holding frame 3 is internal, does not do in the drawings and represents.
In the industrial production, in the use standard of the bucket tools 4 such as dress powder, bucket tool 4 is all that lower edges protrudes, and therefore this barrel of tool 4 dumping machines are also applied to this kind of bucket tool 4. Use the process that this barrel of tool 4 dumping machine installs bucket tool 4 as follows, when needing to load onto bucket tool 4, first holding frame 3 is adjusted to vertical state, then the jaw of gripper clamp is down directed at the upper edge of bucket tool 4, then rotary screw rod 323 so that gripper clamp clamps the chimb of side, outer ring, staving upper edge. Afterwards again toward driving the gas filling some in air pump, guarantee that bucket tool 4 can rise a small distance, then at operation adjusting rod 333, card is pressed down and is rotated further by so that card enters into below the bottom surface of bucket tool 4, after unclamping adjusting rod 333, card can block the lower limb of bucket tool 4 automatically, it is ensured that bucket tool 4 can be installed stable. Such bucket tool 4 just installs, and dismantles if needing that bucket is had 4, then can by above-mentioned steps reverse operating one time.
When by the time bucket tool 4 being installed, people can promote bucket to have 4 dumping machines to have 4 storing places from bucket and transfer to processing district, then utilize and drive cylinder 11 to be risen by adjustable shelf 2, be rotated further by manual pulley 21 and just can complete toppling over of material, very efficient and convenient.
The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
