Specifically, in one possible embodiment, as shown in fig. 2 and 4, the conveying mechanism 2 includes a conveying belt 21, and a plurality of ventilation holes 25 are uniformly formed in the conveying belt 21. The conveying mechanism 2 further comprises a driving wheel 26, a driving motor and a plurality of carrier rollers 27, the driving motor is arranged on the frame 1, the output end of the driving motor is in transmission connection with the driving wheel 26, the carrier rollers 27 are in rotation connection on the frame 1, and the conveying belt 21 is arranged around the driving wheel 26 and the carrier rollers 27. The driving motor drives the driving wheel 26 to rotate so as to drive the conveying belt 21 to convey, the circulating conveying of the conveying belt 21 is realized under the cooperation of the carrier roller 27, and the conveying belt 21 conveys the construction waste mixed with the wood matters and the cement stones from the input end to the output end.
The conveyor belt 21 comprises a guide section 22, a dividing section 23 and a connecting section 24 which are connected into an integral structure.
In the present invention, it should be noted that the material guiding section 22, the material dividing section 23 and the connecting section 24 are not specific to the fixed portion of the conveyor belt 21, but are specific portions of the conveyor belt 21 that are present at the fixed structure of the frame 1 under the action of the conveyor belt 21 on the frame 1, based on the structure of the entire frame 1.
In order to ensure that the best effect of the separation of the wood and stone in the construction waste is achieved, the guide section 22 is specifically a part of the structure arranged along the horizontal direction of the frame 1, the guide section 22 is arranged obliquely, and the height of the guide section 22 is gradually increased from the input end to the output end.
The material separation section 23 is arranged at the output end of the conveying belt 21, and the material separation section 23 is arranged along the vertical direction of the frame 1. Namely, the material dividing section 23 refers to a part of the conveying belt 21 structure which is vertically arranged on the frame 1.
The connecting section 24 connects the material guiding section 22 and the material dividing section 23.
Wherein the material guiding section 22 and the material separating section 23 are connected with the suction port 31.
Below the conveying means 2 is arranged a negative pressure suction means 3, in particular, in one possible embodiment, as shown in fig. 3-5, the negative pressure suction means 3 comprises a suction opening 31, a conduit 32 and a blower 33, the suction opening 31 being in communication with the suction opening of the blower 33 via the conduit 32; suction port 31 is located at the output end of conveyor belt 21, suction port 31 is provided under conveyor belt 21, and suction port 31 is provided in a sealed manner with respect to said conveyor belt 21, so that suction port 31, conveyor belt 21 and frame 1 form a sealed space. Preferably, the conduit 32 is provided as a hose.
Since the ventilation holes 25 are formed in the conveyor belt 21, the suction port 31 is communicated with the ventilation holes 25. The suction port of the fan forms negative pressure so as to adsorb the wood stone on the conveying belt through the suction port and the ventilation holes, and the adsorption force is larger than the inertia force so as to realize the separation of the wood stone.
Specifically, during operation, building rubbish is carried from the input end to the output end of the guide section 22 of the conveying belt 21, when building rubbish reaches the suction port 31, the fan 33 works, the suction port sucks air to enable the suction port 31 to form negative pressure, as a plurality of ventilation holes 25 are uniformly formed in the conveying belt 21, building rubbish is adsorbed on the surface of the conveying belt 21 through the ventilation holes 25, when the conveying belt 21 continues to convey, the suction force of the negative pressure suction port mechanism 3 on the wooden matters with lighter weight is greater than the gravity, the wooden matters are always adsorbed on the surface of the guide section 22 of the conveying belt 21, the adsorption is continued to the vertical material separation section 23 until the conveying belt 21 where the wooden matters are conveyed to the position where the wooden matters are separated from the suction port 31, namely the position where the wooden matters are separated from the conveying belt 21, namely reaching the connecting section 24, and for the cement stone with greater gravity, the weight is greater than the suction force, at the tail end of the conveying belt 21, namely the cement stone with the effect of the gravity, the wooden matters are thrown out from the material separation section 23, namely the wooden matters are thrown out from the guide section 22, and the wooden matters are separated from the wooden matters.
In addition, an electric box is arranged beside the frame 1 and is electrically connected with the fan 33 and the driving motor. The electric box may control the operation of the blower 33 and the drive motor.
According to actual demand, the rotation speed of the driving motor is controlled to adjust the speed of the conveying belt 21, namely, the belt speed of the conveying belt is set to be in an adjustable mode, and the inertia of the wood blocks with different particle sizes is controlled by adjusting the belt speed of the conveying belt so as to separate the wood blocks with different particle sizes, so that further separation is realized between the wood blocks, and the separation of the building rubbish is guaranteed to achieve the best effect.
Meanwhile, according to the actual requirement, the wind speed of the fan 33 is controlled to adjust the negative pressure, so as to adjust the adsorption force of the negative pressure suction port structure, change the adsorption force to the wooden stones, and also improve the separation effect of the construction waste.
In order to ensure that the separated wood stones can be conveniently recovered, the invention also provides a discharging device. I.e. the output end of the conveyor belt 21 is provided with a discharge channel 4, which discharge channel 4 is located at a position below the dividing section 23. In this way, after passing through the material separating section 23, the wood matters falling down to the connecting section 24 are guided out from the material discharging channel 4, so that the wood matters can be conveniently recovered.
The discharge channel 4 is provided with a guide plate 5 along the horizontal direction of the guide section 22, and the guide plate 5 is provided with an inclined plate structure with the height gradually decreasing from the direction close to the conveyor belt 21 to the direction far away from the conveyor belt 21. In this way, the cement stones thrown out from the output end of the material guiding section 22 under the action of inertia are guided out by the material guiding plate 5, and the cement stones are also convenient to recycle.
In addition, as shown in fig. 6-7, a plurality of carrier rollers 27 positioned in the suction port 31 are set as ventilation carrier rollers 28, the ventilation carrier rollers 28 are set as round rollers, and a plurality of annular grooves 29 which are formed in the round rollers around the circumference of the round rollers at equal intervals. The arrangement of the annular groove 29 ensures that the contact area between the ventilation carrier roller 28 and the conveying belt 21 is smaller than that of the normal round roller carrier roller 27, thereby being more beneficial to the communication effect between the ventilation holes 25 and the suction ports 31 and further improving the adsorption effect on the wood matters.
Sealing belts 210 are arranged on two sides of the material guiding section 22 on the frame 1, and sealing spaces are formed by the sealing belts 210, the conveying belts 21 and the suction openings 31. Preferably, the sealing tape 210 is made of rubber sealing material. The arrangement of the sealing belt 210 helps to improve the sealing effect between the conveyor belt 21 and the frame 1, helps to ensure the formation of negative pressure, and helps to ensure the strength of negative pressure, and can also improve the adsorption effect.
