Description

Technical Field

[0001] The utility model belongs to the technical field of garbage treatment, and relates to a garbage and sundry conveying and screening device. Background Technique

[0002] At present, in the process of garbage treatment, due to the limitation of garbage sorting technology, many plastic bags, tableware, beverage bottles, chopping boards, etc. in kitchen waste and food waste are not sorted thoroughly, which will cause blockage of equipment during the treatment process, and seriously affect the normal operation of the pretreatment production line of kitchen waste and food waste. Summary of the Invention

[0003] In order to solve the problem that many garbage are not sorted thoroughly in the current garbage treatment process, which affects the operation of garbage treatment equipment and thus affects the garbage treatment efficiency, the utility model provides a garbage and sundry conveying and screening device. By synchronously rotating multiple sieve plates arranged in a staggered manner, while realizing the conveying of most garbage, some bagged garbage and the like are crushed, so that some fine and small garbage falls from the gaps, realizing the sorting of different garbage.

[0004] In order to achieve the above object, the technical solution of the utility model is:

[0005] A garbage and sundry conveying and screening device includes a support frame, a conveying and screening mechanism, a material leveling mechanism and a power mechanism. The conveying and screening mechanism is arranged on the support frame. The conveying and screening mechanism includes a plurality of transmission shafts rotatably arranged on the support frame. A plurality of sieve plates are arranged at intervals on the transmission shafts. The sieve plates on adjacent two transmission shafts are arranged in a staggered manner. A plurality of sieve rods are circumferentially arranged at intervals on both side surfaces of the sieve plates. A plurality of blades are circumferentially and fixedly arranged at intervals on the outer periphery of the sieve plates. A power mechanism is arranged on one side of the support frame for driving the transmission shafts to rotate synchronously. A material leveling mechanism is arranged above the conveying and screening mechanism. The material leveling mechanism is used for spreading the garbage and sundries along the axial direction of the transmission shafts. The garbage is conveyed by synchronously rotating the sieve plates. The blades cut open the bagged garbage to make the garbage inside leak out. The sieve rods are used to prevent some garbage from winding around the sieve plates.

[0006] Preferably, a spacer sleeve is arranged between adjacent sieve plates on the same transmission shaft. The spacer sleeve is sleeved on the corresponding transmission shaft. The spacer sleeve is key-connected to the corresponding transmission shaft. The sieve plate is key-connected to the corresponding transmission shaft. The distance between adjacent sieve plates is ensured by the spacer sleeve, and the distance between sieve plates is adjusted by replacing spacer sleeves of different lengths.

[0007] Preferably, the material leveling mechanism includes a connecting frame fixedly arranged on the support frame. A material leveling plate is fixedly arranged below the connecting frame. The material leveling plate is a V-shaped plate body, and its tip faces the feeding end of the conveying and screening mechanism. There is a gap between the lower end of the material leveling plate and the conveying and screening mechanism. During the garbage conveying process, when the material pile of the garbage is too high, it spreads to both ends of the transmission shaft under the action of the material leveling plate

[0008] Preferably, the material leveling mechanism includes a rotating shaft rotatably arranged on the support frame, and a spiral blade is arranged on the outer peripheral side of the rotating shaft. The rotation of the spiral blade realizes the uniform spreading of the garbage on the conveying and screening mechanism.

[0009] Preferably, a chain transmission mechanism is arranged on one side of the support frame. The multiple output ends of the chain transmission mechanism are respectively connected to the corresponding transmission shafts, and the input end of the chain transmission mechanism is connected to the power mechanism, so as to ensure the synchronous rotation of the multiple transmission shafts through the chain transmission mechanism.

[0010] Preferably, the power mechanism includes a motor and a speed reducer. The output end of the motor is connected to the speed reducer, and the output end of the speed reducer is connected to the chain transmission mechanism. The motor cooperates with the speed reducer to drive the chain transmission mechanism to work.

[0011] Preferably, the cross section of the sieve plate is star-shaped, and the multiple blades are respectively fixedly arranged at the corresponding tips of the star-shaped sieve plate, and the blades extend out of the outer periphery of the corresponding sieve plate. The blades cut open the packages of the bagged garbage, so that the garbage therein leaks out for sorting.

[0012] Preferably, a conveying mechanism is further arranged on the support frame. The conveying mechanism is located below the conveying and screening mechanism and is used for conveying the fine and small garbage falling through the gaps of the sieve plates.

[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model conveys the garbage and sundries through multiple rotating sieve plates and sieve rods. During this process, the blades cut open the garbage (including garbage bags filled with garbage, etc.), so that the garbage can be sorted better.

[0015] 2. The present utility model is provided with multiple sieve rods at both ends of the sieve plate, and the sieve plates on the adjacent transmission rods are arranged in a staggered manner. When the staggered sieve plates rotate, the moving directions of the sieve rods on the side close to each other are opposite (that is, the sieve rods on one sieve plate move downward with the rotation, and the sieve rods on the other sieve plate move upward with the rotation), and the sieve rods with opposite moving directions are staggered, thereby effectively preventing the sieve plate from being wound with garbage.

Specific embodiments

[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0022] As Figures 1 to 4 shown, this embodiment provides a garbage and sundry conveying and screening device, including a support frame 1, a conveying and screening mechanism, a material leveling mechanism, and a power mechanism. A conveying and screening mechanism is provided on the support frame 1 for conveying and sorting garbage. The conveying and screening mechanism includes a plurality of transmission shafts 11 rotatably arranged on the support frame 1. A plurality of sieve trays 2 are arranged at intervals on the transmission shafts 11. The sieve trays 2 are key-connected to the corresponding transmission shafts 11. A spacer sleeve 5 is arranged between adjacent sieve trays 2 on the same transmission shaft 11. The spacer sleeve 5 is sleeved on the corresponding transmission shaft 11 and is key-connected to the corresponding transmission shaft 11. By key connection, it is ensured that the transmission shaft 11 drives the sieve trays 2 and the spacer sleeve 5 arranged thereon to rotate synchronously. By the spacer sleeve 5, the distance between adjacent sieve trays 2 is ensured. At the same time, spacer sleeves 5 of different lengths can be replaced as needed to adjust the distance between adjacent sieve trays 2 to adapt to different garbage sorting requirements. The cross-section of the sieve tray 2 is star-shaped, and the sieve trays 2 on adjacent two transmission shafts 11 are arranged in a staggered manner. A plurality of sieve rods 3 are circumferentially arranged at intervals on both side surfaces of the sieve tray 2, that is, the sieve rods 3 are connected to the end surfaces of the sieve tray 2. When the transmission shaft 11 drives the sieve tray 2 to rotate and convey garbage, on the one hand, the sieve rods 3 support and convey the garbage between adjacent two sieve trays 2. On the other hand, between adjacent two transmission shafts 11, the sieve rods 3 corresponding to one transmission shaft 11 move downward with the rotation of the sieve tray 2, and the sieve rods 3 corresponding to the other transmission shaft 11 move upward with the rotation of the sieve tray 2. Then, the corresponding sieve rods 3 between the two transmission shafts 11 move in a staggered manner and in opposite directions, effectively preventing garbage from winding around the sieve tray 2. At the same time, in this process, fine garbage falls below the conveying and screening mechanism through the gaps between the sieve trays 2 to achieve garbage sorting.

[0023] A plurality of blades 4 are fixedly arranged at intervals in the circumferential direction on the outer periphery of the sieve tray 2. The plurality of blades 2 are respectively fixedly arranged at the corresponding tips of the star-shaped sieve tray 2, and the blades 4 extend out of the outer periphery of the corresponding sieve tray 2. When the sieve tray 2 rotates, the blades 4 are driven to rotate, thereby contacting the conveyed garbage and cutting open garbage bags or other plastic bags, paper towels, etc. containing garbage. On the one hand, it ensures the sorting effect of the garbage and avoids the garbage in the garbage bag being directly conveyed backward and avoiding sorting. On the other hand, the cut garbage falls through the gaps of the sieve tray 2 to ensure the garbage sorting effect.

[0024] A material leveling mechanism is arranged above the conveying and screening mechanism, and the material leveling mechanism is used to disperse the garbage and sundries along the axial direction of the transmission shaft 11.

[0025] As Figure 1 As shown in the figure, the material leveling mechanism includes a connecting frame 6 fixedly arranged on the support frame 1. A material leveling plate 7 is fixedly arranged below the connecting frame 6. The material leveling plate 7 is a V-shaped plate body, and its tip faces the feeding end of the conveying and screening mechanism. The material leveling plate 7 is located in the middle of the connecting frame 6. There is a gap between the lower end of the material leveling plate 7 and the conveying and screening mechanism. When the piled-up conveyed garbage is relatively high, it will contact the material leveling plate 7. Under the action of the material leveling plate 7, the garbage at the high place is diverted to both sides to ensure the garbage sorting effect.

[0026] As an implementable manner, the material leveling mechanism includes a rotating shaft (not shown in the figure) rotatably arranged on the support frame. The rotating shaft can be driven to rotate by a power mechanism. A spiral blade is arranged on the outer peripheral side of the rotating shaft. There is a gap between the lower end of the spiral blade and the conveying and screening mechanism. The rotation of the spiral blade is used to evenly spread the garbage to both sides to ensure the sorting effect.

[0027] A power mechanism is arranged on one side of the support frame 1 for driving the transmission shaft 11 to rotate synchronously. The power mechanism includes a motor 9 and a speed reducer 10. The output end of the motor 9 is connected to the speed reducer 10. A chain transmission mechanism 8 is arranged on one side of the support frame 1. The output end of the speed reducer 10 is connected to the chain transmission mechanism 8. The motor 9 and the speed reducer 10 cooperate to drive the chain transmission mechanism 8 to work. The multiple output ends of the chain transmission mechanism 8 are respectively connected to the corresponding transmission shafts 11. The input end of the chain transmission mechanism 8 is connected to the power mechanism. When the chain transmission mechanism 8 works, it drives the multiple transmission shafts 11 to rotate synchronously. When the transmission shafts 11 rotate, they respectively drive the multiple corresponding sieve trays 2 to rotate.

[0028] A conveying mechanism is further arranged on the support frame 1. The conveying mechanism is located below the conveying and screening mechanism. When the conveying and screening mechanism conveys garbage, the smaller garbage falls onto the conveying mechanism through the gaps between the sieve trays 2. Thus, while realizing garbage sorting, the garbage of different sizes is respectively conveyed for subsequent treatment.

[0029] In use, first, the garbage is transported to the feeding end of the conveying and screening mechanism by means of a conveying mechanism or a garbage truck, etc. The power mechanism and the chain drive mechanism 8 drive a plurality of transmission shafts 11 to rotate synchronously, driving a plurality of screening discs 2 to rotate. The screening discs 2 cooperate with the screening rods 3 to convey the garbage. During the garbage conveying process, the garbage bags or other plastic bags, paper towels, etc. containing garbage are cut open by the blades 4. On the one hand, it ensures the sorting effect of the garbage, avoiding the garbage in the garbage bag being directly conveyed backward and avoiding sorting. On the other hand, the cut garbage falls through the gaps of the screening discs 2, ensuring the garbage sorting effect. Furthermore, the garbage with a smaller volume or in a long strip shape, etc., falls on the lower conveying mechanism through the gaps of the screening discs 2, realizing the separate conveyance and treatment of different garbage. At the same time, during the garbage conveying and sorting process, the screening rods 3 cooperate with each other to prevent the garbage from winding around the screening discs 2.

[0030] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent shall be included in the scope of the present invention's patent application.
