Abstract
The utility model relates to a multi-bucket digger for digging sand, which belongs to the technical field of lifting machinery for loading. Through a way that an upper shovel frame is fixed on a machine frame at the nearest position, the multi-bucket digger can raise the rigidity of the upper shovel frame, meet requirements for the upper shovel frame of a running hopper in a lower shovel frame during digging operation, and can not generate the phenomenon of forced stop because of disengagement of a chain in a maintenance area on the upper part of the lower shovel frame caused by horizontal swing of the upper and the lower shovel frames and the vertical jump of the lower shovel frame. The operating angle of the lower shovel frame only needs to be adjusted before the utility model works, the adjustment is simple, and the work efficiency can be raised by 25%.
Description
The utility model belongs to load uses the elevation and subsidence mechanical technical field.
The multi bucket excavator of brick and tile factory use now; its whole machinery is by shoveling mechanism; walking mechanism; elevating mechanism; belt conveyer structure four parts are formed; relevant with the utility model is elevating mechanism and shoveling mechanism; need adjust respectively before the multi bucket excavator work that brick and tile factory uses now on the critical piece of elevating mechanism and shovel frame; shovel the operating angle of frame down; adjust complicated; the adjustment time is long; because the upper end of last shovel frame is fixed on the transmission axle of driving wheel; the bottom is to hang in the sky with cable wire; the lower end links with hinge and following shovel frame; by driving wheel drive in constituting the double-deck channel-section steel that shovels frame up and down and the shoveling mechanism that forms of the chain that rotates between driven pulley and hopper fixed thereon when being engaged in digging; because the rigidity of last shovel frame is bad; very easily produce double swerve that shovels frame up and down and the bob that shovels frame down; the chain that the drive hopper rotates also very easily shovels the chain maintenance area on the top of frame and jumps out under being positioned at, entire machine is by forced-stopping machine.
The purpose of this utility model provides a kind of good rigidly, adjusts simply before the work, moves multi bucket excavator stably during work.
The purpose of this utility model be achieved in that the shovel frame with screw or other fixed form good with the immediate fixed-site of frame, last shovel frame lower end and shovel frame hinge joint down, satisfied the shoveling mechanism of working on time shovel frame when being engaged in digging on the rigidity requirement of shovel frame, only need to adjust down the operating angle of shovel frame before the work and just can start working.
The utility model is compared with existing multi bucket excavator, only need to adjust the operating angle of shovel frame down before the work, adjust simple, the adjustment time can save 70%, to go up the shovel frame is fixed on the frame, last shovel frame and frame are connected as a single entity, the rigidity of last shovel frame strengthens, shovel shoveling mechanism on the frame down when being engaged in digging, can not produce double swerve that shovels frame up and down and the bob that shovels frame down, fix the chain of hopper and also can in the maintenance area on the top of shoveling frame down, not jump out, can increase work efficiency 25%.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of existing multi bucket excavator
Fig. 2 is the structural representation of most preferred embodiment of the present utility model
With reference to Fig. 1, the upper left quarter of the frame of existing multi bucket excavator (18) is being fixed counterweight bracing frame (16) and is being used to support ballast box (15), one end of cable wire (9) lies in the top of counterweight bracing frame (16), and the other end lies in the top of support (7), and support (7) is fixed on suitable angle.At first need to determine to go up the operating angle of shovel frame (22) before the work, be fixed on the movable pulley (10) on the frame (18) be fixed pulley (6) the back other end of cable wire (8) by support (7) top lie in the bottom of shovel frame (22), will go up and shovel frame (22) and adjust to suitable operating angle; Determine the operating angle of shovel frame (3) down then, the lower end of last shovel frame (22) is by hinge (24) and shovel frame (3) hinge joint down, one end lies on the movable pulley (11) that is positioned on the frame (18), the other end through the fixed pulley (6) on support (7) top, down shovel movable pulley (5) on the frame (3), get back to the cable wire (4) that lies in down behind the fixed pulley (6) on support (7) top on the shovel frame (3) again and will shovel frame down and be fixed on suitable angle, the suitable weight of placement is positioned between two tracks (20) center of gravity of entire machine in counterweight supports case (15).Open motor and drive driving wheel (13) rotation through drive sprocket axle, driving wheel (13) drives chain (1) and shovel frame (22) on constituting, shovel in the double-deck channel-section steel of frame (3) down and back and forth rotation between the driven pulley (2), fix a hopper (12) on the chain (1) at a certain distance, after hopper (12) runs to and cuts the earth on the slope parallel with following shovel frame, earth is scraped in belt transmission mechanism (17) is transferred to the trailer of waiting for earlier on the top when rising near the cleaning shoe (14) on being installed in the driving wheel, track (20) serves as the length that the basis connects into to be needed with sleeper (21), and frame (18) supports complete machine upward needs walking with shoveling by roller (19) at track (20).Because last shovel frame (22) bottom hangs in the sky with cable wire (8); rigidity is bad; the hopper that moves in the double-deck channel-section steel of shovel frame under formation very easily produces double swerve that shovels frame up and down and the bob that shovels frame down when cutting the earth; chain (1) also very easily shovels the maintenance area on the top of frame (3) under being positioned at deviates from, and entire machine is had to shut down.
With reference to figure (2), according to getting the husky requirement of below ground soil, the shovel frame (20) of going up of the present utility model passes through screw (22) good with the immediate fixed-site of frame (16), no longer adjust, support (7) is by hinge (21) and frame (16) hinge joint, the upper end of shoveling frame (3) down is by hinge (23) and last shovel frame (20) hinge joint, cable wire (4) one ends lie on the movable pulley (9) on the frame (16), the other end is through the fixed pulley (6) on support (7) top, shovel the movable pulley (5) at frame (3) middle part down, that gets back to support (7) top again lies in down the bottom of shoveling frame (3) behind the wheel (6) clearly calmly, to shovel frame (3) down and be fixed on suitable operating angle, the upper left quarter that counterweight bracing frame (14) is fixed on frame (16) is supporting ballast box (13), the top other end that cable wire (8) one ends lie in counterweight bracing frame (14) lies in support (7) top, support (7) is fixed on suitable angle, driving wheel (11) rotates to drive to be positioned to constitute goes up shovel frame (20), shoveling the chain (1) that reaches between the driven pulley (2) in the double-deck channel-section steel of frame (3) down rotates, the soil that the hopper of fixing at a certain distance on the chain (1) (10) digs on the slope parallel with following shovel frame (3) is fallen into belt transmission mechanism (15) and is transferred in the pre-prepd trailer to being scraped by cleaning shoe (12) driving wheel (11) near, frame (16) support complete machine by roller (17) based on the track (18) of sleeper (19) upward walking just can carry out the necessarily digging in interval.
Of the present utility model go up the shovel frame be not limited to screw will go up the shovel frame with the immediate fixed-site of frame, also can adopt welding or other fixed form, be fixed on the frame so long as go up the shovel frame, need not adjust before the work, all belong to scope of the present utility model.
