Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but implementation of the present utility model
Mode is not limited only to this.
As shown in figure 1, a kind of gravel conveyor, including frame 1, frame 1 is inclined to set, and the two ends of frame 1 are set respectively
There are driving roller 2 and driven roller 3, be connected between above-mentioned driving roller 2 and driven roller 3 by belt 4.In order to anti-
Only belt 4 skids, and is provided with tensioning apparatus, reference picture 2 positioned at the lower position of belt 4 at the middle part of frame 1, tensioning apparatus includes using
Tension drum 51 in tightening belt, it is arranged on the bend pulley 52 of the top both sides of tension drum 51 and is fixed on tension drum 51
Counter-balanced carriage 6 on axle, bend pulley 52 includes the first roller 521 and second tin roller 522, the belt 4 come from driven roller 3 according to
Secondary the first roller 521, tension drum 51, second tin roller 522 and the driving roller 2 of bypassing is connected, and in the Action of Gravity Field of counter-balanced carriage 6
It is issued to the purpose of tightening belt.
But, material falls on belt 4 suddenly due to conveyer on startup, gives belt downward active force so that
Counter-balanced carriage 6 is moved upwards by the pulling force of belt 4, and during counter-balanced carriage 6 upwards motion, belt 4 is in half tensioning state,
Belt 4 is caused to skid, solid accumulation is in blanking port, so being provided with frame 1 for controlling counter-balanced carriage 6 unidirectional downwards
The limit assembly of motion, to solve the above problems.
Such as Fig. 3, shown in Fig. 4, limit assembly includes the connector 71 that upper end is bolted with frame 1（With frame 1
Do not represented in annexation figure）, connector 71 is hinged with ratchet 72 towards the one end of counter-balanced carriage 6, and counter-balanced carriage 6 is towards the side of ratchet 72
It is provided with the rack 73 engaged with ratchet 72.Wherein, the teeth section setting triangular in shape on rack 73, and its upper surface is in water
The flat or setting that is inclined upwardly；The lower end of ratchet 72 is fitted with the upper surface of teeth, and ratchet 72 is close to the side of teeth lower surface
It is curved to set.In addition, being provided between ratchet 72 and connector 71 when ratchet 72 away from the direction of rack 73 along when rotating
The return unit 74 resetted, return unit 74 can be using spring or elastic blob of viscose or torsion spring.When counter-balanced carriage 6 is by upward pulling force
When, the lower end of ratchet 72 can be prevented ratchet 72 from being rotated to the direction away from counter-balanced carriage 6, so as to reach limit by upward power
Position effect；Conversely, when counter-balanced carriage 6 is by downward pulling force, the upper surface of ratchet 72 is contacted with the lower surface of teeth, ratchet 72
By an active force for being directed away from the direction of counter-balanced carriage 6, so that ratchet 72 departs from rack 73, counter-balanced carriage 6 is transported downwards
It is dynamic, and it is connected teeth of the ratchet 72 again with being positioned above in the presence of elastic component.
Such as Fig. 5, shown in Fig. 6, the weight grade of counter-balanced carriage 6 is adjusted for convenience, the different tensioning demands of belt 4 are met,
Counter-balanced carriage 6 is provided with weight linear meter 61 away from the one end of belt 4, and weight linear meter 61 is threadedly coupled towards the one end of counter-balanced carriage 6 with weight linear meter 61
Have equidistantly to offer to be laminated on multiple pin-and-holes 62, weight linear meter 61 on retainer ring 611, weight linear meter 61 and be provided with balancing weight 63, when
The balancing weight 63 of needs is laminated after connection each along weight linear meter 61, latch 64 and the pin of the lower section of balancing weight 63 positioned at bottom
The grafting of hole 62, so that balancing weight 63 is stuck between retainer ring 611 and latch 64.
In order that balancing weight 63 can be spacing without offseting mutually, it is ensured that belt 4 is tensioned stability, and balancing weight 63 is stacked
Face is provided with inlay card auxiliary section 631, and inlay card auxiliary section 631 includes balancing weight 63 towards the groove 6311 of the side of counter-balanced carriage 6 and remote
From the projection 6312 of the side of counter-balanced carriage 6, adjacent balancing weight 63 is spacing mutually by groove 6311 and projection 6312.
It is convenient to add balancing weight 63 on weight linear meter 61 to be tensioned belt 4 in order to when belt 4 easily skids, counterweight
Bar 61 is provided with base 8 away from the one end of counter-balanced carriage 6, and the base 8 is placed on the ground, and base 8 is set towards the side of counter-balanced carriage 6
There are two to be vertically arranged the pilot hole 632 for being arranged at intervals with and coordinating with guide rod 9 on guide rod 9, balancing weight 63, guide rod 9
Upper end position is flushed with retainer ring 611 or higher than retainer ring 611, and stacking is provided with standby balancing weight 63 on base 8.When need
When adjusting the weight of counter-balanced carriage 6, the balancing weight 63 being placed on base 8 can be slid onto on weight linear meter 61 along guide rod 9,
So as to adjust the quantity of the balancing weight 63 on weight linear meter 61, and guide rod 9 does not produce influence to the balancing weight 63 on weight linear meter 61.
The operation principle of the present embodiment：
When belt 4 is by upward pulling force, the lower surface of ratchet 72 is fitted with the upper surface of teeth on rack 73, makes spine
Pawl 72 is received straight up or towards the active force of counter-balanced carriage 6 so that ratchet 72 is abutted with rack 73 all the time, and reaching prevents skin
With 4 purposes moved up；
And when needing to increase the weight of counter-balanced carriage 6, belt 4 is by downward active force, now, the inside of ratchet 72 and tooth
On bar 73 teeth lower surface contact so that ratchet 72 by an active force for being directed away from the direction of counter-balanced carriage 6 so that
Ratchet 72 departs from rack 73, and counter-balanced carriage 6 is moved downward, and makes ratchet 72 again with being positioned above in the presence of elastic component
Teeth connection；
When needing to reduce the weight of counter-balanced carriage 6, break ratchet 72 into two with one's hands with hand, ratchet 72 is departed from rack 73, counter-balanced carriage 6
Automatic motion upwards, then decontrols hand, reaches the purpose of regulation again.
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
