Description

Technical Field

[0001] The invention relates to garbage sorting equipment, and belongs to the technical field of automatic sorting equipment for bagged domestic garbage. Background Art

[0002] In the sorting and processing of garbage, multiple screening methods are usually required. Existing garbage screening equipment often achieves garbage screening by simply combining multiple functional devices. This has the disadvantages of large mass and volume, complex structure, and high manufacturing and maintenance costs. As shown in the Chinese utility model patent "Authorization Announcement No.: CN207288080U; Authorization Announcement Date: May 1, 2018; Name: A Bag-Packed Lightweight Domestic Waste Recycling Equipment", a bag-breaking mechanism, a vibrating screening mechanism, and an air separation mechanism are provided. When in use, the bag-breaking mechanism is first used to tear the garbage bag to scatter the garbage inside the garbage bag, and then the vibrating screening mechanism and air separation mechanism are used to screen the garbage. Although this garbage screening device can effectively classify domestic garbage, it still has the aforementioned defects and still has shortcomings. Summary of the Invention

[0003] The purpose of the present invention is to provide a new garbage sorting equipment in response to the above-mentioned technical defects of the existing garbage screening device. The garbage sorting equipment is equipped with a bag breaking device and a screening device. The screening roller in the screening device is not only provided with a support plate with lateral pushing and vertical supporting functions, but also a kit with elastic tentacles is provided between the support plates. The elastic tentacles can not only realize the direct vertical drop of heavy garbage and prevent the vertical drop of light garbage, but also can frictionally clean the support plates, and its own elastic characteristics can achieve self-cleaning through its own shaking. The screening device in the sorting equipment is novel and reliable in design, rich in functions, equivalent to a combination of a vibration screening mechanism and an air separation mechanism, compact in structure, with good self-cleaning function, and outstanding practicality.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A garbage sorting device includes a bracket and a feeding device, a bag breaking device and a screening device arranged on the bracket. The bag breaking device is arranged above the feed port of the screening device. The feeding device is used to feed the bag breaking device. The screening device includes a screening roller group arranged in a screening material channel. The screening roller group includes a plurality of screening rollers arranged parallel to each other and equidistantly in the screening material channel. The screening rollers and the screening material channel are perpendicular to each other. The screening rollers include a rotating shaft and support plates and a kit alternately arranged in the axial direction of the rotating shaft. The support plate is perpendicular to the rotating shaft. The outer surface of the kit is provided with a plurality of elastic tentacles. The length of the elastic tentacles is greater than the distance from the outer edge of the support plate to the rotating shaft.

[0006] By adopting the above technical solution, a new type of garbage sorting equipment is provided. The garbage sorting equipment is equipped with a bag breaking device and a screening device. The screening rollers in the screening device are not only provided with support plates with lateral pushing and vertical support functions, but also with a set of elastic tentacles between the support plates. The elastic tentacles not only enable heavy garbage to drop vertically directly and prevent light garbage from falling vertically, but also can frictionally clean the support plates. Their own elastic characteristics enable self-cleaning through their own vibration. The screening device in the sorting equipment is novel and reliable in design, rich in functions, equivalent to a combination of a vibrating screening mechanism and an air separation mechanism. It has a compact structure, good self-cleaning function, and outstanding practicality.

[0007] The present invention is further configured as follows: in the screening channel, a heavy-mass waste collection box is provided directly below the screening roller group, and a light-mass waste collection box is provided below the unloading side of the screening roller group.

[0008] By adopting the above technical solution, garbage collection boxes are specifically arranged below the screening roller and below the discharge side to achieve the sorting of heavy and light garbage.

[0009] The present invention is further configured such that: the support plate is a regular polygon.

[0010] The present invention is further configured as follows: in the screening channel, the support plates on adjacent screening rollers are staggered, and the distance between the rotating shafts of two adjacent screening rollers is smaller than the maximum radial dimension of the support plates.

[0011] By adopting the above technical solution, the support plate is designed into a regular polygon, and the raised portion of the edge of the regular polygon can better realize the function of pushing the material horizontally.

[0012] The present invention is further configured such that the elastic tentacles on the outer surface of the kit are made of elastic rubber or elastic plastic.

[0013] By adopting the above technical solution, the manufacturing material of the elastic tentacles is specifically limited.

[0014] The present invention is further configured as follows: a driving gear is provided at the end of the rotating shaft of the screening roller, and a reversing gear is rotatably provided between the driving gears of adjacent screening rollers. The rotation of all screening rollers in the screening channel is driven by a driving chain that is S-shaped and wound around the driving gear and the steering gear. The driving chain is driven by a power gear arranged at the end of the output shaft of the screening motor.

[0015] By adopting the above technical solution, the drive chain is wound in an S shape on the drive gear at the end of the screening roller, which can avoid the drive chain from slipping and improve the operation stability.

[0016] The present invention is further configured as follows: a plurality of screening roller groups are arranged in the vertical direction of the screening channel.

[0017] By adopting the above technical solution and arranging a plurality of screening roller groups in the vertical direction of the screening channel, the accuracy of screening can be further improved and the garbage screening effect can be improved.

[0018] The present invention is further configured as follows: the bag breaking device includes a bag breaking ratchet roller and a conveying roller, the bag breaking ratchet roller is located directly below the unloading end of the loading device, the conveying roller is located on the side of the bag breaking ratchet roller close to the unloading of the screening material channel, and the linear speed of the outer ring of the conveying roller is greater than the linear speed of the outer ring of the bag breaking ratchet roller.

[0019] By adopting the above technical solution, the conveying rollers and bag-breaking ratchet rollers are reasonably arranged, so that the bag-breaking action and the operation of pushing the material horizontally are smooth and coherent, which can effectively avoid the situation where the material is stuck.

[0020] The present invention is further configured as follows: the feeding device is a belt conveying device, the feeding device and the screening channel are in the same vertical plane, and the feeding direction in the screening channel is opposite to the feeding direction of the feeding device.

[0021] By adopting the above technical solution, the positional relationship between the screening channel and the feeding device is reasonably arranged, so that the sorting equipment is sufficiently compact in the horizontal, longitudinal and vertical directions.

[0022] The main beneficial effects of the present invention are:

[0023] 1. The garbage sorting equipment of the present invention is equipped with a bag breaking device and a screening device. The screening rollers in the screening device are not only provided with support plates with lateral pushing and vertical supporting functions, but also with a set of elastic tentacles between the support plates. The elastic tentacles not only enable heavy garbage to drop vertically directly and prevent light garbage from falling vertically, but also can rub and clean the support plates. The elastic characteristics of the tentacles themselves can achieve self-cleaning through their own vibration. The screening device in the sorting equipment is novel and reliable in design, rich in functions, and is equivalent to a combination of a vibrating screening mechanism and an air separation mechanism. It has a compact structure, good self-cleaning function, and outstanding practicality.

DETAILED DESCRIPTION

[0034] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figures 1 to 3 As shown, a garbage sorting device includes a bracket 5 and a feeding device 1, a bag breaking device 3 and a screening device 4 arranged on the bracket 5. The bag breaking device 3 is arranged above the feeding port of the screening device 4, and the feeding device 1 is used to feed the bag breaking device 3.

[0037] The bag breaking device 3 includes a bag breaking ratchet roller 12 and a conveying roller 13. The bag breaking ratchet roller 12 is located directly below the discharge end of the feeding device 1, and the conveying roller 13 is located on the side of the bag breaking ratchet roller 12 close to the discharge of the screening material channel. The linear speed of the outer ring of the conveying roller 13 is greater than the linear speed of the outer ring of the bag breaking ratchet roller 12.

[0038] The screening device 4 includes a screening roller assembly 15 disposed within the screening channel. The screening roller assembly 15 comprises a plurality of screening rollers arranged parallel to each other and equidistantly within the screening channel. The screening rollers are perpendicular to the screening channel. The screening rollers include a rotating shaft 20 and support plates 17 and sleeves 19 alternately disposed in the axial direction of the rotating shaft 20. The support plates 17 are regular polygons perpendicular to the rotating shaft 20. The outer surface of the sleeve 19 is provided with a plurality of elastic tentacles 18. The elastic tentacles 18 are made of elastic rubber or elastic plastic. The length of the elastic tentacles 18 is greater than the distance from the outer edge of the support plate 17 to the rotating shaft 20. Within the screening channel, the support plates 17 on adjacent screening rollers are staggered, and the distance between the rotating shafts 20 of two adjacent screening rollers is less than the maximum radial dimension of the support plates 17. A driving gear 8 is provided at the end of the rotating shaft 20 of the screening roller, and a reversing gear 9 is rotatably provided between the driving gears 8 of adjacent screening rollers. The rotation of all screening rollers in the screening channel is driven by a drive chain 10 that is S-shaped and wound around the driving gear 8 and the steering gear 9. The drive chain 10 is driven by a power gear 11 arranged at the end of the output shaft of the screening motor 16.

[0039] A heavy-mass waste collection box 6 is provided directly below the screening roller group 15 , and a light-mass waste collection box 7 is provided below the unloading side of the screening roller group 15 .

[0040] The feeding device 1 is a belt conveying device. The feeding device 1 and the screening channel are located in the same vertical plane. The feeding direction in the screening channel is opposite to the feeding direction of the feeding device 1 .

[0041] Example 2:

[0042] The difference between the second embodiment and the first embodiment is that a plurality of screening roller groups 15 are provided in the vertical direction of the screening channel, which can further improve the ability of screening garbage.

[0043] How it works:

[0044] The mixed garbage bag is placed at the lower end of the feeding device 1, and the feeding device 1 transports the garbage bag to the top of the bag breaking device 3, and puts the garbage bag into the bag breaking device 3 from the feed guide groove plate 2. The bag breaking ratchet roller 12 in the bag breaking device 3 punctures the garbage bag. At the same time, the conveying roller 13 rotates rapidly to pull the garbage bag, so that the mixed garbage in the garbage bag is scattered out, and the scattered garbage falls directly onto the screening roller group 15. After screening and pushing by the screening roller group 15, small-sized and large-mass garbage collapses the elastic tentacles 18 and falls directly into the heavy-mass garbage collection box 6. Large-sized and small-mass garbage cannot collapse the elastic tentacles 18, and is pushed to the light-mass garbage collection box 7 on the discharge side by the support plate 17 and the elastic tentacles 18, thereby realizing the screening of heavy-mass garbage and light-mass garbage. In addition, during the screening process, the elastic tentacles 18 can clean the support plate 17 by continuously beating and rubbing the support plate 17. At the same time, the elastic tentacles 18 can achieve self-cleaning through their own shaking.
