Description

Technical Field

[0001] This utility model belongs to the technical field of garbage cleaning equipment, and specifically relates to an unmanned garbage bin loading and cleaning equipment. Background Technology

[0002] With the increasing need for urban greening, more and more garbage trucks have been put into use on the market. However, in the process of using common garbage trucks, such as the garbage truck with the public number CN215665265U, it is still necessary to manually transport the garbage bins filled with garbage to the tipping mechanism of the garbage truck, and then the tipping mechanism of the garbage truck will dump the garbage bins.

[0003] Existing autonomous vehicle technology is becoming increasingly sophisticated. For example, the technology presented in the patent document CN109765895B, when used for garbage collection, is still subject to the defects mentioned above. It relies on manual labor to transport the garbage bins full of garbage to the tipping mechanism of the garbage truck, so it cannot achieve fully unmanned garbage bin cleaning. Therefore, existing technology requires a garbage bin cleaning vehicle or equipment that combines autonomous vehicles to achieve fully unmanned garbage bin cleaning. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned garbage bin loading and cleaning device to solve the technical problem in the background art that it is impossible to completely achieve unmanned garbage bin cleaning.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An unmanned garbage bin loading and cleaning device includes: an unmanned vehicle, a garbage bin outer cylinder, and a garbage bin inner liner; the unmanned vehicle tows a garbage bin, and two sets of vertical steel frame lifting frames are fixed to the end of the garbage bin. Each of the two sets of lifting frames has a sliding mechanism slidably engaged on its opposite surface. A frame structure moving frame is rotatably engaged between the two sets of sliding mechanisms via a deflection shaft. The moving frame has an opening on the side away from the unmanned vehicle; the garbage bin has an upper opening near the lifting frame to form a feeding port; a lifting power mechanism is provided between the top or bottom of the lifting frame and the sliding mechanism to drive the sliding mechanism up and down; a rotational power mechanism is provided on the sliding mechanism to drive the deflection shaft to deflect; the garbage bin inner liner is an upper-opening cylindrical structure with bottom wheels, and is embedded in a shell-structured garbage bin outer cylinder. The bottom of the garbage bin outer cylinder has a ramp, and the bottom wheels of the garbage bin inner liner are placed on the ramp; the garbage bin outer cylinder has an opening on the lowest point of the ramp for the garbage bin inner liner to pass through, and at least one set of electronic latches is provided on the opening side to restrict the downward sliding of the garbage bin inner liner.

[0007] Furthermore: vertical slots are provided on the opposite surfaces of the two sets of lifting frames, and a slide rail is fixed on each side of the slot. The main body of the sliding mechanism consists of two sets of clamping plates, which are clamped on both sides of the slide rail on the same side. The two sets of clamping plates are connected by shafts, and a pulley is rotatably fitted on each shaft. The pulley and the side of the slide rail adjacent to it form a rolling fit.

[0008] Furthermore: the main body of the rotary power mechanism is a low-speed motor, which is bolted to the clamping plate of the sliding mechanism on the same side. A drive gear is fixed on the output shaft of the low-speed motor. A driven gear is concentrically fixed to the side end of the deflection shaft through a coupling. The driven gear and the drive gear mesh with each other, and the number of teeth of the driven gear is greater than the number of teeth of the drive gear.

[0009] Furthermore: the lifting power mechanism is a multi-stage hydraulic rod or a multi-stage electric cylinder. The fixed end of the lifting power mechanism is fixed to the bottom or top of the lifting frame, and the telescopic end of the lifting power mechanism is fixedly connected to the clamping plate of the sliding mechanism on the same side through the connecting seat.

[0010] Furthermore: In order to temporarily fix the inner liner of the trash can when it is transported to the outer cylinder of the trash can, so as to facilitate the extension limit of the electronic pin, an electromagnet is provided inside the outer cylinder of the trash can. When the inner liner of the trash can is transported to the outer cylinder of the trash can, the inner liner of the trash can and the electromagnet are attached to each other; at least the side of the inner liner of the trash can closest to the electromagnet is made of iron or iron-containing material.

[0011] Furthermore: To prevent the bottom wheels from causing the inner liner of the trash can to roll and shift within the moving frame, the width between the bottom wheels below the inner liner is smaller than the width of the inner liner, creating a support position between the bottom wheels and the adjacent sides of the inner liner. Support bars of angle steel structure are provided on both sides of the lower part of the moving frame to support the inner liner; pre-reserved grooves for accommodating the bottom wheels are provided between the support bars.

[0012] Furthermore: In order to allow the inner liner of the trash can to slide accurately into the moving frame under the action of gravity, a block-shaped placement platform is provided at the side opening of the outer cylinder of the trash can; the top surface of the placement platform is flush with the lowest point of the slope, or the top surface of the placement platform is inclined away from the outer cylinder of the trash can; the width of the placement platform is greater than the width between the bottom wheels below the inner liner of the trash can, and the width of the placement platform is less than the width of the reserved groove; the wheel direction of the bottom wheel is fixed, and the side of the bottom wheel is provided with a guide rail to prevent the bottom wheel from deviating from its movement; the guide rail is fixed on the slope; the bottom wheel is located inside the guide rail, and the guide rail is parallel to the side of the inner liner of the trash can, providing a single motion guide for the bottom wheel to slide downward.

[0013] Furthermore, in order to prevent the inner liner of the trash can from detaching from the moving frame when the trash is dumped, two sets of rod-shaped limiting posts are provided at the upper opening of the moving frame, wherein the limiting post closer to the unmanned vehicle is the first limiting post; and the limiting post farther away from the unmanned vehicle is the second limiting post.

[0014] Furthermore, to prevent the first limiting post from blocking the dumping of garbage, the first limiting post is cut off in the middle without affecting its limiting function, so that an opening is formed between the first limiting posts that does not affect the tilting and sliding of garbage.

[0015] Furthermore, to prevent rainwater from entering the inner liner of the trash can, the top of the outer cylinder of the trash can is a ring-shaped frame structure with a canopy supported by a column at least 20 centimeters high, which covers the top of the opening.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This system, combined with existing programming technology, can achieve fully automated trash can cleaning: An unmanned vehicle, an outer trash can casing, and an inner trash can liner are installed. An external control mechanism retracts an electronic latch, releasing the inner trash can liner from its restraints. Under the weight of the inner liner itself and the trash it contains, the bottom wheels of the inner liner slide onto a temporary platform, guided by a guide rail, placing the inner liner inside the moving frame. At this point, the external control mechanism controls a lifting mechanism to extend or retract, driving the moving frame and sliding mechanism upwards until the lifting bars on the moving frame contact the lifting positions at the bottom of the inner trash can liner. The inner trash can then rests in the moving frame via these lifting positions. The bottom wheels of the inner liner are now positioned in the pre-drilled slots in the two sets of lifting bars and are not in contact with the moving frame. At this point... An external control mechanism controls the lifting power mechanism to drive the moving frame and sliding mechanism upwards by extending or shortening until the upper opening of the garbage bin's inner liner moves above the feeding port. At this point, the external control mechanism controls a low-speed motor to rotate, which drives a drive gear to rotate. The drive gear drives a driven gear that meshes with it to rotate as well. The driven gear drives a deflection shaft to rotate through a coupling, which in turn drives the moving frame and the garbage bin's inner liner to rotate. The low-speed motor continues to rotate in the same direction until the original upper opening position of the garbage bin's inner liner is lower than the original bottom of the inner liner. Under the action of gravity, the garbage is poured out of the garbage bin's inner liner and enters the garbage bin through the feeding port for collection. Based on the above principle, the structure disclosed in this application can achieve unmanned garbage collection operations by programming, thus saving labor costs. Attached Figure Description

[0029] Please see Figures 1-9 The present invention provides the following technical solution:

[0030] An unmanned garbage bin loading and cleaning device includes: an unmanned vehicle 1, a garbage bin outer cylinder 9, and a garbage bin inner liner 10; the unmanned vehicle tows a garbage bin 2, and two sets of vertical steel frame lifting frames 3 are fixed to the end of the garbage bin 2. Each of the two sets of lifting frames 3 has a sliding mechanism 7 slidably engaged on its opposite surface. A frame structure moving frame 4 is rotatably engaged between the two sets of sliding mechanisms 7 via a deflection shaft 45. The moving frame 4 has an opening on the side away from the unmanned vehicle 1; the garbage bin 2 has an upper opening forming a feeding port 21 on the side near the lifting frames 3; a drive mechanism is provided between the top or bottom of the lifting frames 3 and the sliding mechanism 7. The sliding mechanism 7 has a lifting power mechanism 5 that moves up and down, and the sliding mechanism 7 is equipped with a rotation power mechanism 6 that drives the deflection shaft 45 to deflect. The inner liner of the trash can 10 is an open cylindrical structure with a bottom wheel 101. The inner liner of the trash can 10 is embedded in the outer cylinder 9 of a shell structure. The bottom of the outer cylinder 9 of the trash can is provided with a ramp 92, and the bottom wheel 101 of the inner liner of the trash can 10 is placed on the ramp 92. The outer cylinder 9 of the trash can is provided with an opening on one side of the lowest point of the ramp 92 for the inner liner of the trash can 10 to pass through. The opening side is provided with at least one set of electronic latches 94 for restricting the downward sliding of the inner liner of the trash can 10.

[0031] Vertical slots are provided on the opposite surfaces of the two sets of lifting frames 3. A slide rail 31 is fixed on each side of the slot. The main body of the sliding mechanism 7 consists of two sets of clamping plates 71. The two sets of clamping plates 71 are respectively clamped on both sides of the slide rail 31 on the same side (this same side is the slide rail 31 on the first set of lifting frames 3). The two sets of clamping plates 71 are connected by shafts. A pulley 72 is rotatably fitted on each set of shafts. The pulley 72 and its adjacent slide rail 31 side form a rolling fit.

[0032] The main body of the rotary power mechanism 6 is a low-speed motor 61. The low-speed motor 61 is fixed to the clamping plate 71 of the sliding mechanism 7 on the same side by bolts (the bolts are not shown in the figure for simplicity). A drive gear 62 is fixed on the output shaft of the low-speed motor 61. A driven gear 63 is concentrically fixed to the side end of the deflection shaft 45 through a coupling 64. The driven gear 63 and the drive gear 62 mesh with each other, and the number of teeth of the driven gear 63 is greater than the number of teeth of the drive gear 62.

[0033] The lifting power mechanism 5 is a multi-stage hydraulic rod or a multi-stage electric cylinder. The fixed end of the lifting power mechanism 5 is fixed to the bottom or top of the lifting frame 3, and the telescopic end of the lifting power mechanism 5 is fixedly connected to the clamping piece 71 of the sliding mechanism 7 on the same side through the connecting seat 73.

[0034] An electromagnet 95 is installed inside the outer cylinder 9 of the trash can. When the inner liner 10 of the trash can is transported into the outer cylinder 9 of the trash can, the inner liner 10 of the trash can and the electromagnet 95 are attached. The inner liner 10 of the trash can is made of iron or iron-containing material at least on the side closest to the electromagnet 95.

[0035] The width between the bottom wheels 101 below the inner liner of the trash can is less than the width of the inner liner of the trash can, so that a lifting position is formed between the bottom wheels 101 and the adjacent side of the inner liner of the trash can. The lower two sides of the moving frame 4 are provided with lifting bars 41 of angle steel structure for supporting the lifting position of the inner liner of the trash can; the lifting bars 41 are provided with reserved grooves 42 for accommodating the bottom wheels 101.

[0036] The outer cylinder 9 of the trash can has a single-piece placement platform 8 at its side opening. The top surface of the placement platform 8 is flush with the lowest point of the slope 92, or the top surface of the placement platform 8 is inclined away from the outer cylinder 9 of the trash can. The width of the placement platform 8 is greater than the width between the bottom wheels 101 below the inner liner 10 of the trash can, and the width of the placement platform 8 is less than the width of the reserved groove 42. The wheel direction of the bottom wheel 101 is fixed. The side of the bottom wheel 101 is provided with a guide rail 93 to prevent the bottom wheel 101 from deviating from its movement. The guide rail 93 is fixed on the slope 92. The bottom wheel 101 is located inside the guide rail 93. The guide rail 93 is parallel to the side of the inner liner 10 of the trash can and is a single movement guide for the bottom wheel 101 to slide downward.

[0037] The upper opening of the motion frame 4 is provided with two sets of rod-shaped limiting posts, of which the limiting post closer to the unmanned vehicle 1 is the first limiting post 43; and the limiting post farther away from the unmanned vehicle 1 is the second limiting post 44.

[0038] Without affecting its limiting function, the first limiting post 43 is cut off in the middle, so that an opening is formed between the first limiting posts 43 that does not affect the tilting and sliding of the garbage.

[0039] The top of the outer cylinder 9 of the trash can is a ring-shaped frame structure with an opening 91. Behind the opening 91, a canopy 96 is supported by a column of no less than 20 centimeters, which covers the top of the opening 91.

[0040] Brief description of usage:

[0041] In use, the lifting power mechanism 5, low-speed motor 61, electronic pin 94, electromagnet 95 are connected to an external control mechanism, power supply circuit, and remote control circuit. The remote control circuit and the unmanned vehicle 1 form a wireless connection (the unmanned vehicle 1 is a direct application of this application, and its own structure and circuit are not within the protection scope of this application, so they are omitted. For its application object, please refer to CN114275077A. This application only protects the structure. The circuit composition itself is an external mechanism and is not within the protection scope of this application, so it is omitted).

[0042] like Figure 2As shown, when the inner liner 10 of the trash can is in use, it is located on the ramp 92 inside the outer cylinder 9 of the trash can. The extended electronic pin 94 limits the inner liner 10, preventing it from sliding off the ramp 92. Trash can be thrown into the inner liner 10 from the opening 91 and collected by the inner liner 10. When the unmanned vehicle 1 arrives with the trash bin 2 to collect the trash, the moving frame 4 is at its lowest position. The unmanned vehicle runs a pre-set program according to the placement of the outer cylinder 9, reversing to align the moving frame 4 behind the trash bin 2 with the opening on the outer cylinder 9 for the inner liner 10 to pass through, until the reserved slot 42 on the moving frame 4 is located on both sides of the adjacent platform 8 (e.g., ...). Figure 8 (As shown in state A).

[0043] At this time, the electronic latch 94 is retracted via an external control mechanism. The retracted electronic latch 94 releases the restriction on the inner liner 10 of the trash can. Therefore, under the weight of the inner liner 10 itself and the weight of the trash it contains, the bottom wheel 101 of the inner liner 10 slides onto the temporary placement platform 8 under the guidance of the guide rail 93, placing the inner liner 10 inside the moving frame 4 (e.g., ...). Figure 8 (As shown in state B).

[0044] At this time, through the external control mechanism, the lifting power mechanism 5 is controlled to drive the moving frame 4 and the sliding mechanism 7 upward by extending or shortening, until the lifting bar 41 on the moving frame 4 contacts the lifting position at the bottom of the trash can inner liner 10. Then, the trash can inner liner 10 is placed in the moving frame 4 through the lifting position. The bottom wheel 101 under the trash can inner liner 10 is now located in the reserved groove 42 in the two sets of lifting bars 41 and does not contact the moving frame 4 (e.g., Figure 8 (As shown in state C).

[0045] At this time, through the external control mechanism, the lifting power mechanism 5 is controlled to drive the moving frame 4 and the sliding mechanism 7 to move upward as a whole by extending or shortening, until the upper opening of the inner liner 10 of the garbage can moves above the feeding port 21 (e.g., Figure 8 (As shown in states D and E).

[0046] At this time, the low-speed motor 61 is controlled to rotate by an external control mechanism. The low-speed motor 61 drives the drive gear 62 to rotate, and the drive gear 62 drives the driven gear 63 meshing with it to rotate as well. The driven gear 63 drives the deflection shaft 45 to rotate through the coupling 64. The deflection shaft 45 drives the moving frame 4 and the inner liner of the garbage can 10 inside to rotate (e.g., Figure 8 (as shown in state F).

[0047] The low-speed motor 61 continues to rotate in the same direction until the original upper opening of the inner liner 10 of the garbage bin is lower than the original bottom of the inner liner 10. Under the action of gravity, the garbage is poured out of the inner liner 10 and enters the garbage bin 2 through the feeding port 21, where it is collected (e.g., Figure 8 As shown in state G), when dumping garbage, the first limiting post 43 and the second limiting post 44 are used to limit the original upper opening of the garbage bin inner liner 10 to prevent the garbage bin inner liner 10 from detaching from the moving frame 4 (the garbage bin 2 is equipped with a unloading door, and after the garbage bin 2 is full, it can be cleaned by opening the unloading door).

[0048] After the trash in the inner liner 10 is emptied, the motion frame 4 and the inner liner 10 are reset in the same manner as described above, following the steps in state GFEDCB. In state B, the inner liner 10 is placed on the temporary platform 8 via its bottom wheels 101, with the bottom wheels 101 and the temporary platform 8 forming a rolling engagement. At this time, the unmanned vehicle 1 starts the reversing procedure, and the motion frame 4 behind the unmanned vehicle 1 pushes the inner liner 10 and the bottom wheels 101 to move as a whole into the outer cylinder 9 of the trash can until the inner liner 10 and the bottom wheels 101 move from the top surface of the temporary platform 8 onto the ramp 92. The garbage can is pushed by ramp 92 to the inner liner 10 of the garbage can and into contact with electromagnet 95. At this time, the electromagnet 95 is controlled by an external control mechanism to work, and the electromagnet 95 temporarily attracts the inner liner 10 of the garbage can to prevent it from slipping. At this time, the unmanned vehicle 1 starts the forward program until the moving frame 4 on the unmanned vehicle 1 detaches from the outer cylinder 9 of the garbage can. Then, the electronic pin 94 is controlled by the external control mechanism to extend again and limit the inner liner 10 of the garbage can. At this time, the external control mechanism shuts off the electromagnet 95 to avoid continuous power consumption. Then the unmanned vehicle 1 can continue the cleaning operation of the next garbage point according to the predetermined program.

[0049] Based on the above principles, the disclosed structure of this application allows for the development of a program to achieve unmanned garbage collection operations, thereby saving labor costs.

[0050] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
