The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The first embodiment is as follows:
referring to fig. 1 to 7, the present invention provides a cement mortar vibration compaction system, which has the following technical scheme:
the utility model provides a cement mortar plain bumper system, which comprises a base 1, install rocking arm 2 on the base 1, the end connection of rocking arm 2 places platform 3, be equipped with actuating mechanism 4 and a supporting bench that are located and place platform 3 below on the base 1, a supporting bench includes control box 7 and installs load seat 8 on control box 7 roof, mounting groove 9 has been seted up on load seat 8's top, the inside slip of mounting groove 9 has set stop block 10, movable rod 11 is installed to stop block 10's bottom, threaded rod 12 is pegged graft to the bottom spiral of movable rod 11, threaded rod 12 rotates and installs on control box 7, install drive threaded rod 12 pivoted control assembly on the control box 7, still install the locking mechanism who mutually supports with control assembly on the control box 7.
The height of the stop block 10 can be adjusted by turning the threaded rod 12 to return it to a suitable position, thereby ensuring the tapping effect.
Referring to fig. 3, wherein the control assembly includes a driven gear 13 fixedly installed at the bottom end of the threaded rod 12, a rotating shaft 16 is vertically inserted on the inner bottom wall of the control box 7, a driving gear 15 engaged with the driven gear 13 is installed on the rotating shaft 16, and the top end of the rotating shaft 16 extends to the upper side of the control box 7 and is installed with a knob 17.
Further, the radius R1 of the driving gear 15 and the radius R2 of the driven gear 13 are 1: 2-4.
The knob 17 is rotated to drive the driving gear 15 to rotate, the driving gear 15 drives the driven gear 13 to rotate so that the threaded rod 12 rotates, the height of the stop block 10 is adjusted, the radius of the driving gear 15 is smaller than that of the driven gear 13, the rotating speed of the driven gear 13 is reduced, the angle change range of the driven gear 13 is reduced, the height of the stop block 10 can be adjusted more accurately and faster, and the adjustment time is shortened.
Referring to fig. 4, the locking mechanism includes a locking disk 14 and a locking plate 22 which are matched with each other, the periphery of the locking disk 14 is uniformly provided with notches, the locking disk 14 is fixedly installed at the bottom of the driven gear 13, the tail end of the locking plate 22 is provided with a connecting rod 23, the connecting rod 23 extends to the outside of the control box 7 and is connected with a pull ring 24, and the connecting rod 23 is sleeved with a return spring 25.
In a natural state, the locking plate 22 is pressed against the locking disk 14 by the action force of the return spring 25, so that the locking disk 14 cannot rotate, the threaded rod 12 cannot rotate, and the threaded rod 12 cannot rotate reversely even if the stop block 10 is knocked repeatedly during a jolt operation, so that the stability of the stop block 10 is remarkably improved and the number of times of adjustment is reduced. When the height of the stop block 10 needs to be adjusted, the pull ring 24 is pulled to separate the lock plate 22 from the lock disk 14, the lock disk 14 is unbound, and the threaded rod 12 can be rotated.
2-3, a containing box 18 is installed on the outer wall of the bearing seat 8, a liquid inlet pipe 21 communicated with the bottom of the installation groove 9 is connected to the bottom wall of the containing box 18, and non-Newtonian liquid is contained in the containing box 18.
Non-newtonian liquids are characterized by a difficulty in deforming when subjected to a violent impact, and by a tendency to deform and flow only when subjected to a gentle force. The non-newtonian liquid at the bottom of the stop block 10 may therefore provide support to the stop block 10 when the stop block 10 is subjected to vibrations, further improving the stability of the stop block 10, thereby reducing the number of adjustments.
Furthermore, a box cover 19 is installed at the top end of the containing box 18, and a one-way air inlet valve 20 is installed on the box cover 19.
When the stop block 10 is adjusted upwards, the non-Newtonian liquid is supplemented into the mounting groove 9, the one-way air inlet valve 20 can supplement air pressure into the containing box 18 in time, and the box cover 19 can prevent sundries from falling into the containing box 18.
The non-Newtonian liquid of the present invention may be a mixture of starch and clear water at a ratio of 3:1, or may be of other well known types, and will not be described in detail herein.
In addition, a top frame 5 is arranged on the base 1, an impact block 6 is arranged on the bottom wall of the rocker arm 2, and a limiting insertion rod 28 movably inserted on the top frame 5 is installed at the bottom end of the impact block 6.
The stability of the rocker arm 2 and the placing table 3 in the moving process can be improved through the limiting insertion rod 28, so that the rocker arm and the placing table cannot deviate in the horizontal direction, and the stability of the equipment is improved.
In addition, a piezoelectric ceramic 30 is attached to the top end of the top frame 5, and a rubber pad 29 is provided between the piezoelectric ceramic 30 and the top frame 5.
The piezoelectric ceramic 30 can generate current when the impact block 6 impacts the top frame 5, and the current can be stored for the driving mechanism 4 to use, so that energy is saved.
Example two:

Taking fig. 7 as an example, in a natural state, the lock lever 27 is stopped on the ratchet wheel to prevent the ratchet wheel from rotating counterclockwise, and when the stop block 10 is impacted, the threaded rod 12 tends to rotate counterclockwise, so that the stop block 10 cannot move down, and the stability of the stop block 10 is ensured. When the stop block 10 needs to be moved upwards, the threaded rod 12 can be driven to rotate by slowly rotating the knob 17, the operation is simple, other auxiliary operations are not needed, and the requirement on proficiency is high.
The working principle is as follows: the knob 17 is rotated to drive the driving gear 15 to rotate, the driving gear 15 drives the driven gear 13 to rotate so that the threaded rod 12 rotates, the height of the stop block 10 is adjusted, the radius of the driving gear 15 is smaller than that of the driven gear 13, the rotating speed of the driven gear 13 is reduced, the angle change amplitude of the driven gear 13 is reduced, the height of the stop block 10 can be adjusted more accurately and more quickly, and the adjustment time is reduced; in a natural state, the locking plate 22 is pressed against the locking disk 14 by the action force of the return spring 25, so that the locking disk 14 cannot rotate, the threaded rod 12 cannot rotate, and the threaded rod 12 cannot rotate reversely even if the stop block 10 is knocked repeatedly during a jolt operation, so that the stability of the stop block 10 is remarkably improved and the number of times of adjustment is reduced. When the height of the stop block 10 needs to be adjusted, the pull ring 24 is pulled to separate the lock plate 22 from the lock disk 14, the lock disk 14 is unbound, and the threaded rod 12 can be rotated; and the non-newtonian liquid at the bottom of the stopper 10 can provide support to the stopper 10 when the stopper 10 is vibrated, further improving the stability of the stopper 10, thereby reducing the number of times of adjustment.
