All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2-7, the present invention provides the following technical solutions: the integral mechanical equipment is used for conveying on the basis of a conveying belt and comprises a conveying driving assembly 1 and a layered discharging assembly 2 which are sequentially arranged along the conveying direction of coal; the layered discharging assembly 2 comprises a transverse moving mechanism 21 and a longitudinal moving mechanism 22 which are vertically connected, wherein the transverse moving mechanism 21 changes the conveying discharging position of the conveying belt in the transverse direction, and the longitudinal moving mechanism 22 changes the conveying discharging height of the conveying belt in the longitudinal direction.
Specifically, the use state of the whole mechanical equipment can be referred to fig. 7:
during initial conveying, the discharging position of the layered discharging assembly 2 is a position a; as the quantity of the coal conveyed and discharged is increased, and the discharging position of the layered discharging assembly 2 is transversely moved based on the driving of the transverse moving mechanism 21, namely, the layered discharging assembly is moved from a position to b position, so that the discharging stacking of the first layer i is completed; then, based on the driving of the longitudinal moving mechanism 22, the discharging position of the layered discharging assembly 2 is moved longitudinally, i.e. from the first layer i to the second layer ii, and then the discharging process moving from a to b is repeated; and in the processes of moving upwards and returning from the position b to the position a, the conveying driving assembly 1 stops driving, so that the intermittent conveying of the whole equipment is formed, and effective layered conveying and discharging are realized.
Based on the structure, specifically:
as shown in fig. 2, the conveying driving assembly 1 includes two cross frames 11 symmetrically arranged, and a driving motor 12, a driving roller 13 and a driven roller 14 sequentially installed between the two cross frames 11, wherein the driving motor 12 and the driving roller 13 are driven by a belt or a chain, and the driven roller 14 rotates based on the conveying of the conveying belt.
As shown in fig. 3, the transverse moving mechanism 21 includes a first sliding slot 211 opened on the two cross frames 11, and a first hydraulic rod 212 and a first sliding block 213 installed in the first sliding slot 211, the first hydraulic rod 212 drives the first sliding block 213 to move transversely in the first sliding slot 211, and a cantilever connecting plate 214 is fixed on the first sliding block 213 and connected to the longitudinal moving mechanism 22 through the cantilever connecting plate 214;
specifically, during the transverse movement, the first hydraulic rod 212 is driven to extend and retract, so as to drive the first slider 213 to move transversely, and the first slider 213 drives the longitudinal moving mechanism 22 to move transversely through the cantilever connecting plate 214, thereby completing the transverse change of the discharging position.
As shown in fig. 4, the longitudinal moving mechanism 22 includes a mounting frame 221 connected to the cantilever connecting plate 214, and a second sliding slot 222 opened in the mounting frame 221, a second hydraulic rod 223 and a second sliding block 224 are installed in the second sliding slot 222, and the second hydraulic rod 223 drives the second sliding block 224 to move up and down in the second sliding slot 222; in addition, a discharging guide roller 23 is installed between the two second sliders 224, and the discharging guide roller 23 rotates based on the conveyance of the conveying belt.
Specifically, during the longitudinal movement, the second hydraulic rod 223 extends and retracts to drive the second slide block 224 to move longitudinally, and the second slide block 224 drives the discharging guide roller 23 to move longitudinally, so that the longitudinal change of the discharging position is completed.
To sum up:
as shown in fig. 5, the tension assembly 3 is further included, the tension assembly 3 includes an elastic mechanism 31 and a tension guide roller 32, and the tension guide roller 32 moves up and down based on the cooperation of the elastic mechanism 31 and the transmission belt to realize the tension adjustment of the transmission belt.
Preferably, the elastic mechanism 31 includes a first vertical frame 311 integrally formed at the bottom of the cross frame 11, and a third sliding chute 312 provided on the first vertical frame 311, and a third sliding block 313 and a spring 314 are installed in the third sliding chute 312, and the tensioning guide roller 32 is installed on the third sliding block 313 and moves up and down in the third sliding chute 312 based on the expansion and contraction of the spring 314;
specifically, the third sliding chute 312 is only in a stretching state in a normal state, so that a downward pulling force is generated on the third sliding block 313 and the tensioning guide roller 32; as can be seen from the use of fig. 7, the tensioning roller 32 effects the tensioning adjustment of the entire conveyor belt by moving up and down: for example, when the layered discharging assembly 2 moves from a to b, the tension of the entire conveyor belt is reduced, and at this time, the third sliding block 313 and the tensioning guide roller 32 move downwards due to the rebounding pull-down of the third sliding block 313, so that the tension of the conveyor belt is increased, and the conveyor belt can still be conveyed normally; for another example, when the layered discharge assembly 2 moves from the first layer i to the second layer ii, the tension of the whole conveyor belt is also reduced, and the tension of the conveyor belt is ensured based on the same pull-down principle, so as to meet the requirement of the layered discharge assembly 2 in layered conveying and discharging.
As shown in fig. 6, the device further comprises a guiding and limiting assembly 4, which comprises a second vertical frame 41 integrally formed at the bottom of the cross frame 11, and a limiting guide roller 42 installed on the second vertical frame 41, and the conveying belt passes through the limiting guide roller 42 along the conveying direction;
in particular, the guide limiting assembly 4 is provided with the limiting guide roller 42 at a position shown in fig. 7, so as to limit the position of the conveying belt between the discharging guide roller 23 and the limiting guide roller 42, and avoid the influence of the conveying belt on the discharged stacked coal layer.
In addition, in the above structure, the two cross frames 11, the first vertical frame 311 and the second vertical frame 41 which are integrally formed at the bottom of the cross frame 11 are combined to form a frame of the whole mechanical equipment, so that the requirement of stable support of the equipment is met.
