Description

Technical Field

[0001] The present invention specifically relates to the technical field of garbage sorting, and more specifically, to a garbage resource utilization sorting device. Background Art

[0002] With the acceleration of the urbanization process, the amount of construction waste generated by the construction industry is huge. Traditional construction waste treatment methods such as landfilling and open-air stacking not only occupy a large amount of land resources, but also easily cause environmental problems such as soil pollution and water pollution; when collecting construction waste centrally, a large amount of steel bars and iron wires may be mixed in, which cannot effectively ensure the classification of construction waste and may cause resource waste;

[0003] Currently, for the steel bars or iron wires existing in traditional construction waste, manual sorting is usually adopted. A large amount of labor is required during sorting, the labor intensity of sorting is relatively high, and the efficiency is low, and the continuous operation effect cannot be effectively achieved;

[0004] After retrieval, Chinese Patent Publication No. CN202311749551.3 discloses a construction waste sorting machine; including a frame and a crusher, a vibration feeding device is rotatably installed on the side wall of the frame, a conveyor one is arranged below the frame, the crusher is located on one side of the frame, the feeding port of the crusher is docked with the feeding device, and a separating device for separating steel bars and cement is placed on the side of the crusher away from the frame, and the separating device is aligned with the discharge port of the crusher;

[0005] When sorting the steel bars in the construction waste by the device in the above patent, the steel bars in the waste on the conveyor two are adsorbed by the magnetic iron bars. Since the magnetic iron bars are installed on the conveyor two, the magnetic iron bars can only adsorb the steel bars within the corresponding magnetic adsorption range. Although multiple magnetic iron bars are provided in the above patent, the steel bars outside the common magnetic adsorption range of two adjacent magnetic iron bars cannot be effectively sorted out, which will cause incomplete sorting and affect the sorting quality and efficiency. Summary of the Invention

[0006] The object of the present invention is to provide a garbage resource utilization and sorting device. In the device, the first conveyor belt and the second conveyor belt are rotated in opposite directions to achieve the effect of transportation. When the first conveyor belt is transmitting, the semicircular gears installed on the rotating shafts at both ends of the first conveyor belt are meshed with the toothed plates, so that the toothed plates and the crossbeams effectively drive the magnetic suction plate to move downward, so as to effectively achieve the effective adsorption effect of the steel bars in the construction waste transmitted by the first conveyor belt. After the teeth in the semicircular gear are separated from the toothed plates, the toothed plates are reset upward by the first spring arranged inside the rectangular groove, so that the magnetic suction plate is away from the first conveyor belt. In the process of steel bar adsorption, due to the different sizes of building stones, in order to ensure the sorting effect of the magnetic suction plate, a second spring is sleeved on the sliding column, which effectively facilitates the effect of the magnetic suction plate tilting due to the different volumes of the stones, thereby ensuring the adsorption effect of the steel bars in the construction waste; after the sorting is completed, the stones are transmitted to the crushing assembly through the second conveyor belt to achieve crushing processing, which is convenient for subsequent processing; so as to solve the problems of the above-mentioned background technology.

[0045] By adopting the above technical solution, during use, construction waste is transported into the feeding box 4 through a conveying device. During the falling process of the construction waste, the dust generated is blown into the dust collection channel 2 by a blower 8 for centralized collection, thereby avoiding the situation that a large amount of dust pollutes the surrounding working environment. After the dust separation is completed, larger stones and steel bars fall onto the first conveyor belt 51. Through the transmission of the first conveyor belt 51, the up - and - down movement of the magnetic attraction assembly 7 is realized, so as to effectively sort the steel bars in the construction waste.

[0048] By adopting the above technical solution, when conveying through the conveying component 5, the driving motor 53 drives the first driven sprocket 515 installed on one end of the rotating shaft of the second conveyor belt 52 to rotate through the driving sprocket 516 and the first chain 54. At the other end of this rotating shaft, a third driven sprocket 513 and a second driven sprocket 514 are fixedly installed. Among them, the third driven sprocket 513 is cooperatively connected with the fourth driven sprocket 512 installed on one end of the rotating shaft 511 of the first conveyor belt 51 through the figure-eight chain 56, and the first conveyor belt 51 and the second conveyor belt 52 are rotated in opposite directions through the figure-eight chain 56;

[0049] Furthermore, when the fourth driven sprocket 512 drives the first conveyor belt 51 to rotate through the rotating shaft 511, the teeth in the semi-circular gear 510 installed on the rotating shaft 511 mesh with the toothed plate 71, realizing the downward pressure on the toothed plate 71, and realizing the downward movement of the cross beam 70 through the L-shaped fixing block 75. The fixing plate 72 installed on the L-shaped fixing block 75 drives the magnetic attraction plate 73 to move downward. Due to the different sizes of the stones, the magnetic attraction plate 73 can be effectively tilted according to the size of the stones through the sliding of the sliding column 76 along the fixing plate 72 and the contraction of the second spring 74, so as to effectively ensure the effective adsorption of the steel bars on the first conveyor belt 51 by the magnetic attraction plate 73;

[0051] Two guide rods 55 are also cooperatively arranged at the top of the second conveyor belt 52 near the crushing component 6; the guide rods 55 are movably installed on the cross bar of the frame body 50 through rotating shafts;

[0052] By adopting the above technical solution, when the toothed plate 71 moves downward through the semi-circular gear 510, the toothed plate 71 slides along the chute opened on the fixed frame 57, and at the same time, the first spring 59 arranged in the rectangular groove 58 at the bottom of the toothed plate 71 is compressed. After the teeth on the semi-circular gear 510 are separated from the toothed plate 71, the first spring 59 arranged in the rectangular groove 58 resets upward, thereby realizing driving the toothed plate 71 to move upward. When the toothed plate 71 moves upward, the magnetic attraction plate 73 is far away from the first conveyor belt 51 through the cross beam 70 and the fixing plate 72, thereby realizing the effect of reciprocating adsorption;

A driving gear 64 and a driven gear 63 are respectively installed on the same-end rotating shafts of the first crushing roller 61 and the second crushing roller 62, so as to realize the synchronous rotation of the first crushing roller 61 and the second crushing roller 62, effectively ensuring the crushing effect on the stones and facilitating the recycling of construction waste.

[0056] The working principle of the present invention is: when in use, the construction waste is transported into the feed box 4 through the conveying device. The dust generated during the falling process of the construction waste is blown into the dust collection channel 2 by the blower 8 for centralized collection, thus avoiding the situation that a large amount of dust pollutes the surrounding working environment. After the dust separation is completed, the larger stones and steel bars fall onto the first conveyor belt 51. Through the transmission of the first conveyor belt 51, the up and down movement of the magnetic attraction assembly 7 is realized, thus effectively sorting the steel bars in the construction waste. After the sorting is completed, the stones are then transported to the crushing assembly 6 through the second conveyor belt 52 for crushing, thus facilitating the recycling of construction waste.

[0057] When being conveyed by the conveying assembly 5, the driving motor 53 drives the first driven sprocket 515 installed on the rotating shaft at one end of the second conveyor belt 52 to rotate through the driving sprocket 516 and the first chain 54. A third driven sprocket 513 and a second driven sprocket 514 are fixedly installed at the other end of this rotating shaft. Among them, the third driven sprocket 513 is cooperatively connected with the fourth driven sprocket 512 installed on the rotating shaft 511 at one end of the first conveyor belt 51 through an "8" - shaped chain 56, and the first conveyor belt 51 and the second conveyor belt 52 are rotated in opposite directions through the "8" - shaped chain 56.

The fixing plate 72 installed on the L-shaped fixing block 75 drives the magnetic adsorption plate 73 to move downward. Due to the different sizes of the stones, the magnetic adsorption plate 73 can be effectively tilted according to the size of the stones through the sliding of the sliding column 76 along the fixing plate 72 and the contraction of the second spring 74, thus effectively ensuring that the magnetic adsorption plate 73 effectively adsorbs the steel bars on the first conveyor belt 51;

[0059] When the toothed plate 71 moves downward through the semi-circular gear 510, the toothed plate 71 slides along the chute opened on the fixed frame 57. At the same time, the bottom of the toothed plate 71 compresses the first spring 59 arranged in the rectangular groove 58. After the teeth on the semi-circular gear 510 are separated from the toothed plate 71, the first spring 59 arranged in the rectangular groove 58 resets upward, thereby realizing driving the toothed plate 71 to move upward. When the toothed plate 71 moves upward, the magnetic adsorption plate 73 is driven away from the first conveyor belt 51 through the cross beam 70 and the fixing plate 72, thus realizing the effect of reciprocating adsorption;

[0060] The construction waste sorted by the magnetic adsorption plate 73 is transferred to the second conveyor belt 52. There is a baffle 9 at one end of the first conveyor belt 51 and the second conveyor belt 52, thus effectively avoiding the situation of construction waste spilling. When it is transferred to the crushing assembly 6 through the second conveyor belt 52, the first crushing roller 61 and the second crushing roller 62 inside the box body 60 are used to crush the stones;

[0061] When crushing, the second driven sprocket 514 installed on the rotating shaft at one end of the second conveyor belt 52 is connected to the mating sprocket 67 installed on the rotating shaft of the first crushing roller 61 through the second chain 65, thus effectively ensuring the synchronous rotation effect of the first crushing roller 61 and the second conveyor belt 52. The driving gear 64 and the driven gear 63 are respectively installed on the same-end rotating shafts of the first crushing roller 61 and the second crushing roller 62, thus realizing the synchronous rotation of the first crushing roller 61 and the second crushing roller 62, effectively ensuring the crushing effect on the stones, and facilitating the realization of the recycling of construction waste.
