Description

Technical Field

[0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to an automatic lifting conveyor for solid waste. Background Art

[0002] Solid waste refers to solid and semi-solid waste materials generated by human production, consumption, life and other activities, such as solid particles, slag, kitchen waste, etc. Kitchen waste mainly includes leftovers, leftover rice, vegetable leaves, fruit peels, egg shells, tea dregs, bones and scallops. In the process of transporting kitchen waste, a conveyor is needed to transport the low-lying garbage to the upper port of the processing equipment.

[0003] Since leftovers, fruit peels, eggshells and bones in kitchen waste are relatively viscous after mixing, they are very easy to adhere to the surface of the conveyor belt in the conveyor during transportation, thereby affecting the subsequent transportation of solid waste. In response to the above technical problems, the applicant has retrieved some prior art, such as the Chinese patent with patent publication number CN216835806U. When in use, scraping teeth and scraping plates are arranged at the bottom of the conveyor belt, and the solid waste adhered to the conveyor belt is cleaned from the bottom of the conveyor belt by the scraping teeth and scraping plates. However, since the scraping teeth and scraping plates always clean the conveyor belt, the degree of adhesion between the transported solid waste and the conveyor belt is low, and since the conveyor belt will generate vibration and other effects during transportation, the solid waste adhered to the conveyor belt and has not fallen off will fall from the conveyor belt at will during the rotation of the conveyor belt, resulting in a poor environment around the equipment, which needs to be cleaned again later, increasing the workload. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic lifting conveyor for solid waste, aiming to solve the technical problem in the prior art that the solid waste adhered to the conveyor belt cannot be cleaned in time, resulting in the solid waste falling randomly during the rotation of the conveyor belt.

[0005] The present invention is implemented as follows: an automatic lifting conveyor for solid waste comprises a base, a mounting frame is arranged on the base, one end of the mounting frame is rotatably connected to the base and a telescopic member for driving the mounting frame to rotate is arranged on the base, a conveyor belt is rotatably installed in the mounting frame and a first rotating power member for driving the conveyor belt to rotate is arranged on the mounting frame;

[0006] The conveyor belt is fixedly installed with multiple groups of mounting shafts which are linearly spaced along the length direction of the conveyor belt, and a push plate is rotatably installed on the mounting shaft. The conveyor belt is fixedly installed with multiple groups of baffles which are distributed corresponding to the position of the push plate. The push plate contacts the baffle when it rotates to be perpendicular to its moving direction. A limit plate is fixedly installed in the mounting frame, and the limit plate is located at the discharge end of the conveyor belt and below the conveyor belt. One end of the push plate contacts the limit plate and rotates around the mounting shaft.

[0007] Further technical solution: a slot is provided at one end of the push plate away from the baffle plate, the baffle plate is located in the slot when in contact with the push plate, and a magnet for adsorbing the baffle plate is fixedly installed in the slot.

[0008] Further technical solution: A first scraper is fixedly installed in the mounting frame, the first scraper is located at the lower part of the discharging end of the conveyor belt, the first scraper is in sliding contact with the surface of the conveyor belt, and the first scraper is provided with a second through groove and a first through groove for the push plate and the baffle to pass through.

[0009] Further technical solution: the width of the second through slot is the same as the width of the push plate, and the push plate passes through the second through slot after leaving the baffle and rotating ninety degrees.

[0010] Further technical solution: the first through slot is located on the moving track of the baffle plate and when the baffle plate passes through the first through slot, both side surfaces thereof are in sliding contact with the first scraper plate.

[0011] Further technical solution: a support plate is fixedly installed on the side of the first scraper, and a second scraper is slidably installed on the support plate. The second scraper is in sliding contact with the surface of the conveyor belt and the moving trajectory of the second scraper passes through the first through groove. An elastic member is fixedly installed on the support plate, and one end of the elastic member away from the support plate is fixedly connected to the second scraper. When the baffle approaches the second scraper, it pushes the second scraper to move away from the first through groove.

[0012] Further technical solution: A pressure plate is fixedly installed at the end of the second scraper, and an angle is set between the pressure plate and the second scraper. When the baffle moves, it contacts the pressure plate and pushes the second scraper to move.

[0013] Further technical solution: a base plate is fixedly installed on the mounting frame at the feeding end of the conveyor belt, two groups of parallel distributed synchronous wheels are rotatably installed on the base plate, and a second rotating power component that drives one group of synchronous wheels to rotate is fixedly installed on the base plate, and a synchronous belt is installed to rotate together with the synchronous wheels, and two groups of vertical rods are fixedly installed on the synchronous belt. When the synchronous belt drives the vertical rods to rotate, the vertical rods contact the push plate and push the push plate to rotate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. When the push plate rotates to the bottom of the conveyor belt, one end of the push plate contacts the limit plate. As the conveyor belt drives the push plate to move continuously, the limit plate applies a thrust to the end of the push plate, so that the other end of the push plate is separated from the baffle and rotates. When the push plate rotates, it can scrape and clean the area where solid waste is piled in front of its moving direction on the conveyor belt, avoiding the solid waste that is adhered to the conveyor belt during the rotation process from falling randomly on the way, realizing the timely cleaning of solid waste on the conveyor belt, thereby ensuring the cleanliness of the environment during the solid waste transportation process, and no need to clean up the spilled solid waste later, reducing the manual workload.

[0016] 2. The space on the conveyor belt is divided by push plates, and the ends of the push plates are restricted by baffles, so that the solid waste is distributed in the area between the push plates. At this time, the solid waste above it is blocked and restricted by the push plates below, thereby ensuring that the solid waste can be transported upward with the conveyor belt, avoiding the problem of solid waste sliding downward due to accumulation on the conveyor belt, and ensuring the efficiency and stability of solid waste transportation.

[0017] 3. Since the conveyor belt is in sliding contact with the first scraper, the first scraper can scrape and clean the area that the push plate cannot cover when rotating, so that the surface of the conveyor belt can be completely cleaned to ensure the cleanliness of the surface of the conveyor belt. At the same time, when the push plate passes through the second through groove, the first scraper will scrape and clean the two sides of the push plate, and when the baffle passes through the first through groove, its two sides will also be cleaned, further reducing the residual solid waste on the conveyor belt.

[0018] 4. When the push plate moves to the turning area at the lower end of the conveyor belt, the vertical rod pushes the push plate to rotate to reduce the distance between the push plate and the baffle, so that the height difference of the subsequent push plate when freely rotating under the action of gravity is smaller, reducing the impact of the push plate on the baffle, thereby increasing the stability of the conveyor belt when transporting solid waste and reducing the probability of solid waste falling due to impact vibration during transportation.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1-Figure 5 As shown, an automatic lifting conveyor for solid waste provided by the present invention comprises a base 1, a mounting frame 2 is arranged on the base 1, one end of the mounting frame 2 is rotatably connected to the base 1 and a telescopic member 3 for driving the mounting frame 2 to rotate is arranged on the base 1, a conveyor belt 4 is rotatably installed in the mounting frame 2 and a first rotating power member 5 for driving the conveyor belt 4 to rotate is arranged on the mounting frame 2;

[0031] A plurality of mounting shafts 6 linearly spaced along the length direction of the conveyor belt 4 are fixedly installed on the conveyor belt 4, a push plate 7 is rotatably installed on the mounting shaft 6, a plurality of baffles 9 corresponding to the positions of the push plates 7 are fixedly installed on the conveyor belt 4, the push plate 7 contacts the baffle 9 when it rotates to a direction perpendicular to its moving direction, a slot 8 is provided at one end of the push plate 7 away from the baffle 9, the baffle 9 is located in the slot 8 when contacting the push plate 7, a magnet 10 for adsorbing the baffle 9 is fixedly installed in the slot 8, a limit plate 23 is fixedly installed in the mounting frame 2, the limit plate 23 is located at the discharge end of the conveyor belt 4 and below the conveyor belt 4, one end of the push plate 7 contacts the limit plate 23 and rotates around the mounting shaft 6.

[0032] In actual application of this embodiment, the base 1 is fixed, the conveyor belt 4 is driven to rotate by the first rotating power member 5, and the mounting frame 2 is driven to rotate by the telescopic member 3 according to the required conveying height, so that the discharge end of the conveyor belt 4 is lifted to the set height, and the solid waste can be put onto the conveyor belt 4. After the solid waste is put onto the conveyor belt 4, it is carried upward by the conveyor belt 4, and the space on the conveyor belt 4 is divided by the push plate 7, and the end of the push plate 7 is restricted by the baffle plate 9, so that the solid waste is distributed in the area between the push plates 7. At this time, the push plate 7 is pushed downward The solid waste above it is blocked and restricted, so as to ensure that the solid waste can be transported upward with the conveyor belt 4, and the problem of solid waste sliding down caused by solid waste accumulation on the conveyor belt 4 is avoided, so as to ensure the efficiency and stability of solid waste transportation. When the push plate 7 rotates to the end of the conveyor belt 4, the solid waste in front of the push plate 7 can fall down to complete the transportation of the solid waste. In the process of the push plate 7 rotating to the bottom of the conveyor belt 4, the push plate 7 will not fall off the baffle plate 9 due to the adsorption of the magnet 10, so as to prevent the push plate 7 from rotating when the mounting shaft 6 passes through the turning area of ​​the conveyor belt 4. After reaching the bottom of the conveyor belt 4, one end of the push plate 7 contacts the limit plate 23. Since the conveyor belt 4 drives the push plate 7 to continue to move, the limit plate 23 will apply a thrust to the end of the push plate 7 so that the other end of the push plate 7 is separated from the baffle plate 9 and rotates. When the baffle plate 9 rotates ninety degrees, the end of the limit plate 23 slides in contact with the side of the baffle plate 9. At this time, the push plate 7 can pass through the area where the limit plate 23 is located, and the push plate 7 will maintain this state under the action of gravity. When the push plate 7 rotates, it can scrape and clean the area where solid waste is piled up on the front side of its moving direction on the conveyor belt 4 The solid waste after cleaning falls directly downward, so that the surface of the conveyor belt 4 after conveying the solid waste can be cleaned, thereby realizing timely cleaning of the solid waste on the conveyor belt 4 and preventing some solid waste adhered to the conveyor belt 4 during the rotation from falling randomly on the way, thereby ensuring a clean and tidy environment during the solid waste transportation process, without the need for subsequent re-cleaning of the spilled solid waste, and reducing manual workload. When the push plate 7 moves to the turning area at the lower end of the conveyor belt 4, the push plate 7 can rotate again under the action of gravity and contact with the baffle 9, and then the solid waste transportation can continue.

[0033] In an example of the present embodiment, the first rotating power component 5 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The conveyor belt 4 is driven by the first motor to rotate, thereby realizing the transportation of solid waste. The telescopic component 3 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The mounting frame 2 is driven to rotate by the electric telescopic rod, thereby realizing the adjustment of the solid waste transportation height.

[0034] like Figure 3 , Figure 6As shown, an automatic lifting conveyor for solid waste provided by the present invention is provided, in which a first scraper 11 is fixedly installed in a mounting frame 2, and the first scraper 11 is located at the lower part of the discharge end of the conveyor belt 4, and the first scraper 11 is in sliding contact with the surface of the conveyor belt 4, and a second through groove 13 and a first through groove 12 for the push plate 7 and the baffle plate 9 to pass through are provided on the first scraper 11.

[0035] Specifically, the width of the second through slot 13 is the same as that of the push plate 7 , and the push plate 7 passes through the second through slot 13 after leaving the baffle plate 9 and rotating 90 degrees.

[0036] Specifically, the first through slot 12 is located on the moving track of the baffle plate 9 and when the baffle plate 9 passes through the first through slot 12 , both side surfaces thereof are in sliding contact with the first scraper plate 11 .

[0037] When the conveyor belt 4 is in actual application, the solid waste on the conveyor belt 4 moves for transportation, and when the conveyor belt 4 rotates to the end where it is installed, the solid waste thereon falls downward, and then the conveyor belt 4 continues to rotate, and the push plate 7 contacts the limit plate 23 to change the placement angle of the push plate 7, and at this time, the push plate 7 is aligned with the position of the second through slot 13, and then the push plate 7 can pass through the first scraper 11 from the second through slot 13, and the baffle 9 passes through the first scraper 11 from the first through slot 12. Since the conveyor belt 4 is in sliding contact with the first scraper 11, the first scraper 11 can scrape and clean the area that the push plate 7 cannot cover during rotation, so that the surface of the conveyor belt 4 can be completely cleaned, ensuring the cleanliness of the surface of the conveyor belt 4. At the same time, when the push plate 7 passes through the second through slot 13, the first scraper 11 will scrape and clean the two side surfaces of the push plate 7, and when the baffle 9 passes through the first through slot 12, its two sides will also be cleaned, further reducing the residual solid waste on the conveyor belt 4.

[0038] like Figure 3 , Figure 7 As shown, an automatic lifting conveyor for solid waste provided by the present invention is provided, a support plate 14 is fixedly installed on the side of the first scraper 11, a second scraper 15 is slidably installed on the support plate 14, the second scraper 15 is in sliding contact with the surface of the conveyor belt 4 and the moving trajectory of the second scraper 15 passes through the first through groove 12, an elastic member 16 is fixedly installed on the support plate 14, one end of the elastic member 16 away from the support plate 14 is fixedly connected to the second scraper 15, and when the baffle 9 approaches the second scraper 15, it pushes the second scraper 15 to move away from the first through groove 12.

[0039] Specifically, a pressing plate 17 is fixedly mounted on the end of the second scraper 15 , and an angle is set between the pressing plate 17 and the second scraper 15 . When the baffle 9 moves, it contacts the pressing plate 17 and pushes the second scraper 15 to move.

[0040] In actual application of this embodiment, when the baffle 9 has not moved to the first scraper 11, the second scraper 15 covers the area of ​​the first through groove 12, so that the second scraper 15 can clean the area on the conveyor belt 4 that the first through groove 12 cannot clean. When the baffle 9 contacts the pressure plate 17, since the pressure plate 17 is arranged at an angle, the continuous movement of the baffle 9 will push the pressure plate 17 to move, thereby causing the second scraper 15 to move away from the first through groove 12 and compress the elastic member 16. At this time, the second scraper 15 no longer blocks the first through groove 12, and the baffle 9 can pass through the first through groove 12. After the baffle 9 no longer contacts the end of the second scraper 15, it can be reset under the action of the elastic member 16, further reducing the area on the conveyor belt 4 that cannot be cleaned, further reducing the residual solid waste on the conveyor belt 4, and improving the cleanliness of the conveyor belt 4.

[0041] In an embodiment of the present invention, the elastic member 16 is a spring. Of course, it can also be other elastic members such as an elastic ball. The spring applies a resetting thrust to the second scraper 15 .

[0042] like Figure 1 , Figure 8 As shown, an automatic lifting conveyor for solid waste provided by the present invention is provided, a base plate 18 is fixedly installed on the mounting frame 2 at the feeding end of the conveyor belt 4, two groups of parallel synchronous wheels 19 are rotatably installed on the base plate 18, and a second rotating power member 21 for driving one group of synchronous wheels 19 to rotate is fixedly installed on the base plate 18, and a synchronous belt 20 is installed to rotate together with the synchronous wheels 19, and two groups of vertical rods 22 are fixedly installed on the synchronous belt 20, and when the synchronous belt 20 drives the vertical rods 22 to rotate, the vertical rods 22 contact with the push plate 7 and push the push plate 7 to rotate.

[0043] When the present embodiment is actually used, the second rotating power member 21 drives one of the synchronous wheels 19 to rotate, thereby making the synchronous belt 20 drive the two sets of vertical rods 22 to rotate. When the conveyor belt 4 drives the push plate 7 back to the lower end, due to the effect of gravity, the length direction of the push plate 7 is along the moving direction of the conveyor belt 4. At this time, the push plate 7 first extends out of the mounting frame 2. Since the vertical rod 22 is in a rotating state, the vertical rod 22 can push the push plate 7 to rotate from the side of the push plate 7, so that the end of the push plate 7 away from the mounting shaft 6 is close to the baffle 9. During the process of the vertical rod 22 pushing the push plate 7 to rotate, the conveyor belt 4 continues to drive the push plate 7 to move. When the mounting shaft 6 moves to the turning area of ​​the conveyor belt 4, the mounting shaft 6 is moved to the turning area of ​​the conveyor belt 4. The mounting shaft 6 will drive the push plate 7 to rotate upward. When the vertical rod 22 is about to separate from the push plate 7, the push plate 7 is close to the baffle 9. When the inclination direction of the mounting shaft 6 gradually points to the top of the horizontal plane, the push plate 7 can continue to rotate and fall under the action of gravity. Then, the push plate 7 is adsorbed and fixed with the baffle 9 after contact with the baffle 9, thereby completing the reset of the push plate 7. The vertical rod 22 pushes the push plate 7 to rotate to reduce the distance between the push plate 7 and the baffle 9, so that the height difference of the subsequent push plate 7 during free rotation under the action of gravity is smaller, reducing the impact of the push plate 7 on the baffle 9, thereby increasing the stability of the conveyor belt 4 when transporting solid waste, and reducing the probability of solid waste falling due to impact vibration during transportation.

[0044] In an embodiment of the present invention, the second rotating power member 21 is a second motor, and of course, it can also be other components capable of outputting rotating power, such as a hydraulic motor. The second motor drives the vertical rod 22 to rotate, thereby driving the push plate 7 to rotate.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
