Description

Technical Field

[0001] The invention relates to a sweeper device, in particular to a sweeper with the function of automatically collecting and packaging garbage. Background Art

[0002] Currently, for a street sweeper, when the garbage bin onboard is full, the garbage is generally emptied out manually, automatically, or by crushing and packaging.

[0003] Among them, manually dumping the garbage is time-consuming and labor-intensive, not smart enough, and cannot be used on unmanned sweepers;

[0004] For solutions that automatically empty garbage, the process typically involves navigating a sweeper to a fixed location when it detects the bin is full, then performing a series of complex operations to empty the garbage into a specific garbage station or bin. The complex structure of the equipment used to control the movement of garbage from the bin to the garbage outlet can easily lead to equipment failures, which is not conducive to subsequent equipment maintenance. Furthermore, when performing cleaning tasks over long distances, returning to the designated location to empty the garbage wastes wastes time, significantly reducing cleaning efficiency, especially during the autumn leaf-falling season.

[0005] The crushing and packaging method increases the loading capacity of garbage and saves space. However, since the garbage is directly crushed, it is not conducive to the subsequent garbage sorting and recycling, and does not conform to the concept of environmental protection, energy conservation and emission reduction. At the same time, its equipment structure is also very complex, the cost is high, and it is prone to failure. At the same time, it is limited by the large size and high energy consumption of the equipment and cannot be used on small and medium-sized sweepers. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, the purpose of the present invention is to provide a sweeper with automatic garbage collection and packaging function, which can solve the problems of existing manual sweepers and automatic sweepers such as time-consuming and labor-intensive, complex structure and low cleaning efficiency.

[0007] The purpose of the present invention is achieved by adopting the following technical solutions:

[0009] Each garbage bag is provided with a plurality of tensioning hooks arranged at intervals, and the plurality of tensioning hooks of each garbage bag are movably connected to the corresponding tensioning components;

[0010] Multiple tensioning assemblies are separately arranged in the garbage collection shell and are arranged around the closing of the garbage bag, and are used to pull the tensioning hook corresponding to each garbage bag to open the closing of each garbage bag;

[0011] A rigid tightening rope is provided in the curled edge at the closing portion of each garbage bag, and an opening is provided on the curled edge so that a portion of the rigid tightening rope is exposed through the opening;

[0012] The opening of the garbage collection shell is provided with a cabinet door that automatically opens and closes toward the outside of the sweeper body; a garbage packing device is provided on the inner side of the cabinet door; when the cabinet door is opened outward, the rigid tightening rope of the garbage bag is hooked by the garbage packing device to tighten the closing of the garbage bag, and the garbage bag is pulled out of the garbage collection shell under the drive of the cabinet door.

[0013] Furthermore, several garbage bags are stacked together to form a garbage bag assembly, and the corresponding tightening hooks of each garbage bag are stacked to form a corresponding tightening hook assembly; wherein, each tightening hook of the garbage bag on the top layer is located at the top of the corresponding tightening hook assembly, and each tightening hook of the garbage bag on the outermost layer is located at the bottom of the corresponding tightening hook assembly; multiple tightening hook assemblies are arranged on the corresponding tensioning assemblies.

[0014] Furthermore, an elastic tension rope is provided in the curled edge of the garbage bag's closing portion; and a protrusion is provided at the top of each tensioning hook of each garbage bag;

[0015] Each tensioning assembly includes a module housing, an electromagnet, a first spring assembly, a tensioning device, and a second spring assembly; wherein the electromagnet is disposed in the module housing, and the bottom end of the electromagnet is fixedly connected to the bottom of the module housing, and the top end of the electromagnet is fixedly connected to the tensioning device via the first spring assembly; the first spring assembly is driven to move up and down in the module housing by energizing and de-energizing the electromagnet, thereby driving the tensioning device to move up and down in the module housing;

[0016] The cross section of the tensioning device is a U-shaped structure, wherein a second spring assembly is provided inside the tensioning device, and the bottom end of the second spring assembly is fixedly connected to the bottom of the tensioning device, and an elastic deformation component is provided at the top end;

[0017] The module housing is provided with a notch, and the corresponding tightening hook assembly is pressed into the interior of the module housing through the notch and is placed above the elastic deformation component of the tightening device, so that it is clamped between the tightening device and the module housing under the action of the spring deformation component and the second spring assembly;

[0018] A limiting column is provided in the module shell, and the top end of the limiting column is fixed to the top of the module shell. A portion of the tensioning hook located at the top of the corresponding tensioning hook assembly is located inside the module shell, and the other portion is located outside the module shell. The protrusion of the tensioning hook is limited by the limiting column to prevent the tensioning hook located at the top layer from being pulled out by the elastic tensioning rope of the corresponding garbage bag.

[0019] By energizing the electromagnet to drive the first spring assembly, the tensioning device is driven to move downward, thereby driving the corresponding tensioning hook assembly to move downward, so that the tensioning hook located at the top of the corresponding tensioning hook assembly is freed from the restriction of the limiting column and is pulled out of the module shell under the action of the elastic tensioning rope of the corresponding garbage bag; at the same time, the remaining tensioning hook in the corresponding tensioning hook assembly is clamped between the tensioning device and the module shell under the action of the limiting hook, elastic deformation component and second spring assembly provided at the top of the tensioning device and will not be pulled out by the elastic tensioning rope of the corresponding garbage bag;

[0020] By cutting off the power to the electromagnet, the first spring assembly drives the tensioning device to reset and the limit hook at the top of the tensioning device to reset. After the tensioning hook at the top layer of the corresponding tensioning hook assembly pops out to the outside of the module shell under the action of the elastic tensioning rope of the corresponding garbage bag, the protrusion of the tensioning hook is limited by the limit column.

[0021] Furthermore, the tightening hook is a T-shaped tightening hook.

[0022] Furthermore, the tensioning assembly includes a fixed tensioning assembly and a movable tensioning assembly; the movable tensioning assembly is arranged on both sides of the cabinet door; the fixed tensioning assembly is arranged at a position away from the cabinet door;

[0023] The waste collection housing is further provided with a screw device and a first motor that match the movable tensioning assembly. The movable tensioning assembly is slidably mounted on the corresponding screw device via the corresponding first slider, and the screw device is connected to the first motor.

[0024] The first motor drives the corresponding screw device to rotate, and then the corresponding first slider drives the corresponding movable tensioning assembly to move along the corresponding screw device toward the ground, so that the garbage bag without garbage is compressed downward to make way for the garbage bag filled with garbage and pull it out of the garbage collection housing;

[0025] When the garbage bag is pulled out of the garbage collection shell, the first motor drives the screw device to rotate in the opposite direction, and then drives the corresponding movable tensioning assembly to reset through the corresponding first slider.

[0026] Furthermore, there are two screw rod devices, which are symmetrically arranged on both sides of the cabinet door; there are two movable tensioning components, which are respectively slidably installed on the corresponding screw rod devices through the corresponding first sliders, and each screw rod device is electrically connected to the first motor.

[0027] Furthermore, it also includes a cabinet door assembly, which includes a second motor and a chain. The cabinet door is installed on the opening of the garbage collection shell through a hinge; the second motor is fixedly connected to the rotating shaft of the cabinet door through the chain, and then drives the cabinet door to open and close through the chain.

[0028] Furthermore, the garbage packaging device also includes an adapter plate provided on the inner side of the cabinet door, two sliding modules, a drum motor and a sealing module; wherein the two sliding modules are symmetrically provided on the cabinet door; the two ends of the adapter plate are slidably connected to the corresponding sliding modules via corresponding second sliders; the drum motor is mounted on the adapter plate, and the drum is driven by the drum motor to rotate so that the hook on the drum hooks the rigid tightening rope of the garbage bag and drives the sealing module to seal the closing edge of the garbage bag;

[0029] The cabinet door is driven to flip outward by the second motor, and the two ends of the adapter plate slide synchronously on the corresponding sliding module through the corresponding second slider, pulling the garbage bag hanging on the reel hook out of the garbage collection shell; then the reel motor is used to drive the reverse rotation to release the garbage bag from the reel hook and put the garbage bag onto the outside of the sweeper.

[0030] Furthermore, a garbage detection component is provided in the garbage collection shell, and the garbage detection component is provided above the closing end of the garbage bag, for detecting the garbage in the garbage bag to determine whether the garbage bag is full.

[0031] Furthermore, the garbage detection component includes a garbage detection component shell, a cover, a cover driving device and a sensor device arranged in the garbage detection component shell; wherein, the cover is arranged at the bottom opening of the garbage detection component to isolate the sensor device from direct contact with the garbage in the garbage bag; the cover is driven to swing at a regular interval by the cover driving device, so that the sensor device is exposed to detect the garbage in the garbage bag.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The present invention improves the sweeper so that it can be equipped with multiple garbage bags at one time, and cooperates with multiple tensioning components to realize the installation and release of multiple garbage bags.

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0045] The present invention provides a garbage sweeper with automatic garbage collection and packaging functions. The garbage sweeper can carry multiple garbage bags and automatically pack the garbage bags when one of them is full, thereby placing the packed garbage bags in the corresponding positions. This solves the problems of time-consuming and labor-intensive manual garbage disposal and lack of intelligence. It also solves the problems of complex equipment structure, long round-trip time to garbage station, inaccurate garbage detection, and garbage sticking to the garbage bin wall in existing automatic garbage disposal. It also avoids the problem of garbage crushing, which is not conducive to subsequent garbage sorting and recycling. The present invention is applicable not only to unmanned garbage sweepers, but also to manned garbage sweepers.

[0046] The present invention provides a preferred embodiment, a sweeper with garbage collection and packaging, such as Figure 1-9 As shown, the vehicle comprises a cleaning vehicle body 10 , a garbage collecting shell 1 arranged in the vehicle body 10 , a plurality of garbage bags 31 arranged in the garbage collecting shell 1 , and a plurality of tensioning assemblies 2 .

[0047] The sweeper body 10 refers to the frame and body control system of the sweeper, and specifically includes the necessary components of the sweeper, such as the body main control system, the body drive device, and the garbage collection drive device. For example, the body main control system refers to the main control device of the sweeper, such as controlling the movement and stop of the sweeper and the operation of other electrical equipment of the sweeper. The body drive device refers to the drive device that drives the movement and stop of the body, etc. The body main control system is electrically connected to the body drive device to drive the movement of the body. The body drive device may include a servo motor, a servo controller, wheels, and other equipment for driving the movement of the body.

[0048] Similarly, for a street sweeper, the garbage collection drive device refers to a drive device used to collect garbage while the street sweeper is moving, such as a suction cup, a sweeping disc, a drive motor that drives the suction cup and sweeping disc, and other equipment. The main control system, the vehicle drive device, and the garbage collection drive device of the street sweeper are essential equipment for the street sweeper and are also technologies well known to those skilled in the art. The present invention does not provide a detailed introduction. The present invention achieves the functions of automatic collection, packaging, and delivery of garbage by the street sweeper by adding a garbage collection housing 1 to an existing conventional street sweeper.

[0049] Preferably, the cleaning vehicle of the present invention can carry a large number of garbage bags 31 at a time, which can avoid frequent replacement of garbage bags 31. Specifically, Figure 4 As shown, the present invention comprises several stacked garbage bags 31 nested together to form a garbage bag assembly, which is then installed within the garbage collection housing 1. Each time a garbage bag 31 is filled, it is packed and pulled out of the garbage collection housing 1 before the next garbage bag 31 is used. This avoids frequent replacement of garbage bags 31, which can lead to inefficient cleaning of the vehicle. Furthermore, the garbage bags 31 are used to hold garbage within the vehicle body 10, preventing it from directly contacting the vehicle body 10 and becoming stuck to the vehicle, potentially damaging the vehicle's cleaning process.

[0050] More preferably, if Figure 6 As shown, the garbage bag 31 is provided with tensioning hooks 34 arranged at intervals, and each tensioning hook 34 is movably connected to the corresponding tensioning assembly 2.

[0051] like Figure 2 As shown, multiple tensioning components 2 are dispersed in the garbage collection shell 1 and arranged around the closing edge of the garbage bag 31. They are used to pull the tensioning hooks 34 corresponding to the garbage bag 31, so as to open the closing edge of the garbage bag 31 and facilitate the collected garbage to enter the garbage bag 31 from the closing edge of the garbage bag 31.

[0052] When multiple garbage bags 31 are stacked together, the corresponding tensioning hooks 34 of each garbage bag 31 are stacked with the corresponding tensioning hooks 34 of the other garbage bags 31 to form a corresponding tensioning hook assembly. Specifically, each tensioning hook 34 of the garbage bag 31 in the top layer is located at the top of the corresponding tensioning hook assembly, and each tensioning hook 34 of the garbage bag 31 in the outermost layer is located at the bottom of the corresponding tensioning hook assembly.

[0053] More specifically, the tightening hook 34 can be arranged at the closing portion of the corresponding garbage bag 31. In this way, by pulling the corresponding tightening hooks 34 through the multiple tensioning components 2 dispersedly arranged in the garbage collection shell 1, the closing portion of the garbage bag 31 can be stretched open so that the garbage collected by the sweeper can be placed in the garbage bag 31.

[0054] Preferably, when the garbage bags 31 need to be packed, the tensioning assembly 2 releases the multiple tensioning hooks 34 corresponding to the garbage bags 31, thereby releasing the garbage bags 31. In other words, the present invention utilizes the tensioning assembly 2 to facilitate both installation and release of the garbage bags 31. Furthermore, the present invention allows for simultaneous installation of multiple garbage bags 31 and the release of each bag 31, achieving automatic release of the bags 31.

[0055] More preferably, a cabinet door 4 that automatically opens and closes toward the outside of the sweeper body 10 is provided on the opening of the garbage collection housing 1. By opening the cabinet door 4, the garbage bag 31 in the garbage collection housing 1 can be taken out.

[0056] Preferably, if Figure 4-5 As shown, the edge of each garbage bag 31 of the present invention is rolled, and a rigid tightening cord 33 is provided inside the rolled edge. The rolled edge is also provided with an opening, so that a portion of the rigid tightening cord 33 is exposed through the opening. In this way, by pulling the exposed rigid tightening cord 33, the garbage bag 31 can be tightened, and the garbage bag 31 can be packed.

[0057] Furthermore, a garbage packaging device is provided on the inner side of the cabinet door 4. When the cabinet door 4 is opened outward, the garbage packaging device hooks onto the rigid tightening rope 33 of the garbage bag 31 to tighten the opening of the garbage bag 31, and the cabinet door 4 drives the garbage bag 31 out of the garbage collection housing 1. In actual use, the garbage collection vehicle can be controlled to move to the corresponding garbage delivery point, and then the garbage bag 31 is packaged and delivered, achieving fixed-point garbage delivery. The garbage collection vehicle can directly collect and transport the garbage at the corresponding garbage delivery point.

[0058] More preferably, when the garbage bag 31 needs to be packed, it is necessary to first control multiple tensioning components 2 to synchronously release multiple tensioning hooks 34 of the same garbage bag 31, and then use the garbage packing device on the cabinet door 4 to hook the rigid tightening rope 33 of the garbage bag 31 to achieve the packing of the garbage bag 31, and then, driven by the cabinet door 4 opening outward, pull the garbage bag 31 to the outside of the sweeper body 10.

[0059] The present invention can not only realize the automatic storage of collected garbage in the garbage bag 31, but also can pack the filled garbage bag 31 and place it outside the sweeper, thereby solving the problems in the prior art such as the need for manual packing and placement of the garbage bag 31, the inconvenience of operation, and the risk of cross infection. At the same time, the present invention has a simple structure and does not require a very complicated structure or wiring to realize the automatic packing and placement of the garbage bag 31.

[0060] Preferably, an elastic tensioning rope 32 is provided in the curled edge of the garbage bag 31. A protrusion is provided at the top of the tightening hook 34. Figure 6As shown, the tightening hook 34 is a T-shaped tightening hook.

[0061] More preferably, if Figure 3 As shown, each tensioning assembly 2 preferably includes a module housing 21 , an electromagnet 22 , a first spring assembly 23 , a tensioning device 24 , and a second spring assembly 25 .

[0062] The electromagnet 22 is disposed within the module housing 21. The bottom end of the electromagnet 22 is fixedly connected to the bottom of the module housing 21, and the top end is fixedly connected to the tensioning device 24 via a first spring assembly 23. By controlling the power supply to the electromagnet 22, the first spring assembly 23 drives the tensioning device 24 to move up and down within the module housing 21.

[0063] Preferably, the cross-section of the tensioning device 24 is a U-shaped structure, wherein a second spring assembly 25 is provided inside the tensioning device 24, and the bottom end of the second spring assembly 25 is fixedly connected to the bottom of the tensioning device 24, and an elastic deformation component 241 is provided at the top.

[0064] A notch is provided on the module shell 21, and the corresponding tightening hook assembly is installed into the interior of the module shell 21 through the notch and is placed above the elastic deformation component 241 of the tightening device 24, so that it is clamped between the tightening device 24 and the module shell 21 under the action of the elastic deformation component 241 and the second spring component 25.

[0065] A limiting post 243 is provided in the module housing 21 , and a top end of the limiting post 243 is fixed to the top of the module housing 21 .

[0066] Since an elastic tensioning rope 32 is provided inside the rolled edge of the garbage bag 31, the elastic tensioning rope 32 applies an outward force to the tensioning hook 34, so that the part of the tensioning hook 34 located at the top layer in the corresponding tensioning hook assembly is pulled out from the module shell 21, and the limiting column 243 provided at the top end of the module shell 21 restricts the protrusion of the corresponding tensioning hook 31 to prevent the tensioning hook 34 at the top layer from being pulled out by the elastic tensioning rope 32 of the corresponding garbage bag 31.

[0067] In actual use, through the above installation method, the multiple tightening hook assemblies formed by the multiple garbage bags 31 can be respectively installed in the corresponding tensioning assemblies 2.

[0068] When the garbage bag 31 needs to be released, the electromagnet 22 is energized to drive the first spring assembly 23 to drive the tensioning device 24 to move downward, and the limiting column 243 is separated from the protruding portion of the tensioning hook 34 on the top layer, so that the tensioning hook 34 on the top layer is pulled out under the action of the elastic tensioning rope 32 of the corresponding garbage bag 31, thereby releasing the garbage bag 31 on the top layer; at the same time, the limiting hook 242, the elastic deformation component 241 and the second spring assembly 25 set at the top of the tensioning device 24 will clamp the remaining tensioning hook 34 in the corresponding tensioning hook assembly between the tensioning device 24 and the module shell 21, and will not be pulled out by the elastic tensioning rope 32 of the corresponding garbage bag 31. That is, the tightening hook 34 of the garbage bag 31 at the top layer in the garbage bag assembly is released by the above method, while the tightening hooks 34 of the remaining garbage bags 31 are not released. At this time, the garbage bag 31 at the top layer among the remaining garbage bags 31 becomes the garbage bag 31 that currently collects garbage.

[0069] When the multiple tightening hooks 34 of the garbage bag 31 on the top layer are released, the cabinet door 4 is opened to allow the garbage packaging device to hook the rigid tightening rope 33 of the garbage bag 31 to close the garbage bag 31, and with the cabinet door 4 opening outward, the garbage bag 31 is pulled out from the garbage collection shell 1 to the outside.

[0070] In addition, when the garbage bag 31 is pulled to the outside of the sweeper, the garbage bag 31 can be taken out of the garbage packaging device by a staff member or a robot.

[0071] Furthermore, since there are multiple garbage bags 31, to facilitate pulling the topmost garbage bag 31 out of the garbage collection housing 1, the tensioning assembly 2 of the present invention also includes a fixed tensioning assembly 211 and a movable tensioning assembly 212. The fixed tensioning assembly 211 refers to the tensioning assembly 2 fixedly mounted within the garbage collection housing 1. The movable tensioning assembly 212 refers to the tensioning assembly 2 that can move up and down. In this embodiment, the "up and down movement" refers to movement with the ground level as the bottom.

[0072] Since the tensioning assembly 2 is installed on the top of the garbage collection shell 1, in order to make way for the garbage bag 31 filled with garbage, the tensioning assembly 2 located near the cabinet door 4 is made movable in this embodiment. In this way, when the garbage bag 31 needs to be pulled out from the garbage collection shell 1, the movable tensioning assembly 212 is lowered to the ground to the lowest point, thereby driving the remaining garbage bags 31 to move downward, making way for the garbage bag 31 filled with garbage, so that the corresponding garbage bag 31 can be pulled out.

[0073] like Figure 2As shown, the movable tensioning assembly 212 is disposed within the waste collection housing 1, near the cabinet door 4. Also disposed within the waste collection housing 1 are a screw assembly 8 and a first motor 9. The movable tensioning assembly 212 is slidably mounted on the screw assembly 8 via a first slider 7. The screw assembly 8 is electrically connected to the first motor 9, which drives the screw assembly 8, thereby driving the movable tensioning assembly 212 up and down.

[0074] Specifically, when the topmost garbage bag 31 needs to be removed, the first motor 9 drives the screw assembly 8 to rotate, thereby lowering the movable tensioning assembly 212 to its lowest position. Since the topmost garbage bag 31 has been released by the tensioning assembly 2 at this point, the movable tensioning assembly 212, through the tensioning hooks 34 of the other garbage bags 31, compresses the entire garbage bag assembly downward, making way for the released garbage bag 31. Similarly, after the garbage bag 31 is removed, the first motor 9 drives the screw assembly 8 to rotate in the opposite direction, driving the movable tensioning assembly 212 back to its original position, allowing the garbage bag assembly to resume receiving garbage.

[0075] Preferably, the installation height of the fixed tensioning assembly 211 is lower than that of the movable tensioning assembly 212. This allows the opening of the garbage bag 31 to tilt toward the front of the vehicle, allowing garbage to enter the garbage bag 31 in an orderly manner. When the garbage bag 31 needs to be removed, the movable tensioning assembly 212 is lowered to make way for the garbage bag 31 to be pulled out. More preferably, the garbage bag 31 has four tensioning hooks 34, located around the opening of the garbage bag 31. Furthermore, there are four tensioning assemblies 2: two are located on the side away from the cabinet door 4 and are the fixed tensioning assemblies 211; and two are located on either side of the cabinet door 4 and are the movable tensioning assemblies 212.

[0076] Preferably, if Figure 7 As shown, the cabinet door assembly further includes a second motor 41 and a chain 42. The cabinet door 4 is hingedly mounted on the opening of the garbage collection housing 1. The second motor 41 is fixedly connected to the rotating shaft of the cabinet door 4 through a connection, and then drives the cabinet door 4 to open and close through the chain 42.

[0077] Preferably, if Figure 7-8 As shown, the garbage packaging device also includes an adapter plate 45, a sliding module 43, a drum motor 46, and a sealing module 47, located inside the cabinet door 4. There are two sliding modules 43, symmetrically located on the cabinet door 4. The two ends of the adapter plate 45 are slidably connected to the corresponding sliding modules 43 via corresponding second sliders 44. In other words, the adapter plate 45 can slide left and right on the sliding modules 43 via the corresponding second sliders 44. The left and right sliding refers to sliding along the forward direction of the sweeper.

[0078] More preferably, a reel motor 46 is mounted on the adapter plate 45. The reel motor 46 drives the reel to rotate, causing the hook on the reel to hook onto the rigid tightening rope 33 of the garbage bag 31 and tighten the rigid tightening rope 33. At the same time, the sealing module 47 seals the end of the garbage bag 31. Preferably, the sealing module 47 can be implemented by a sealing clamp, a heating rod, a sealing machine, etc., such as a shopping bag sealing machine in a supermarket, or by heating the end of the garbage bag 31 to cause the end to adhere and form a seal. The specific configuration can be determined according to actual needs.

[0079] Specifically, the cabinet door 4 is automatically flipped outward by the second motor 41, and the two ends of the adapter plate 45 slide synchronously on the corresponding sliding module 43 through the corresponding second slider 44, pulling the garbage bag 31 hanging on the reel hook out of the garbage collection shell 1, and then driven by the reel motor 46 to rotate in the opposite direction, so that the garbage bag 31 is released from the reel hook and the garbage bag 31 is placed outside the sweeper.

[0080] The sweeper provided by the present invention can realize automatic collection and transportation of garbage in garbage bags 31, automatic packaging and automatic placement of garbage bags 31, etc., so that multiple functions are integrated into one sweeper. At the same time, since the present invention can realize automatic packaging and automatic placement of garbage bags 31, in actual application, multiple temporary garbage placement points can be set up on the roadside where garbage is collected, and multiple garbage bags 31 can be set up on the sweeper. When each garbage bag 31 of the sweeper is full, it can be placed at the nearest temporary garbage placement point. In this way, staff or robots can collect the garbage bags 31 placed at the temporary garbage placement point, solving the problem of low efficiency caused by the sweeper in the prior art traveling back and forth between the garbage station and the cleaning area.

[0081] Preferably, if Figure 1 As shown, the present invention further includes a garbage detection component 5, which is arranged on the garbage collection housing 1 and located above the closing end of the garbage bag 31, for detecting whether the garbage bag 31 is full of garbage.

[0082] When the garbage bag 31 is full of garbage, the vehicle main control system can control various components to achieve automatic packaging and automatic delivery of the garbage. For example, when the garbage bag 31 is full of garbage, the multiple tensioning components 2 are controlled to release the tensioning hooks 34 of the garbage bag 31, and the tensioning hooks 34 of the remaining garbage bags 31 are reset. The reel motor 46 of the garbage packaging device is then controlled to rotate so that the hook on the reel hooks the rigid tightening rope 33 of the garbage bag 31 and tightens the opening of the garbage bag 31. The cabinet door 4 is then controlled to open outward by the second motor 41. At the same time, the adapter plate 45 slides synchronously on the sliding module 43 via the corresponding second slider 44, thereby driving the reel and the garbage bag 31 on the reel to move out of the garbage collection housing 1, that is, pulling the garbage bag 31 out. The reel motor 46 is driven to drive the reel to rotate in the opposite direction, which can loosen the rigid tightening rope 33 of the garbage bag 31, causing the garbage bag 31 to fall to the outside, thus achieving garbage packaging and delivery. Finally, reset each device in sequence and continue with garbage collection.

[0083] Preferably, if Figure 9 As shown, the garbage detection component 5 includes a garbage detection component housing 51, a sensor device 54 arranged in the garbage detection component housing 51, a cover plate 53 arranged at the bottom of the garbage detection component housing 51, and a cover plate driving device 52 that rotates the cover plate 53.

[0084] When the garbage bag 31 needs to be inspected, the cover plate driving device 52 drives the cover plate 53 to swing so that the sensor device 54 is placed above the closed end of the garbage bag 31 to inspect the garbage in the garbage bag 31.

[0085] When the detection is completed, the cover plate driving device 52 drives the cover plate 53 to reset, and the sensor device 54 is placed inside the garbage detection component shell 51 to prevent garbage from contaminating the sensor device 54 or garbage from sticking to the sensor device 54, resulting in inaccurate detection and other problems.

[0086] More preferably, a sealing strip is provided between the cover plate 53 and the garbage detection component housing 51 to prevent dirt from entering the garbage detection component housing 51 and contaminating the sensor device 54 .

[0087] Preferably, the sensor device 54 can be a camera. By taking a picture of the garbage in the garbage bag 31, the vehicle main control system can determine whether the garbage bag 31 is full. The present invention adopts an openable and closeable sensing detection solution to solve the problem of garbage detection sensors being easily blocked by garbage, resulting in inaccurate detection.

[0088] At the same time, the garbage bags 31 are automatically packed and put in by the tensioning component 2 and the garbage packing device, thereby solving the defects of the traditional garbage sweeper that requires manual and automatic garbage disposal.

[0089] In addition, the power devices in this embodiment all come from the vehicle body main control system. By connecting the above-mentioned sensor device 54, motor, drive device, electromagnet 22, etc. to the vehicle body main control system of the sweeper, the drive control of each device can be achieved.

[0090] The cleaning vehicle of the present invention can simultaneously hold dozens of garbage bags 31. After accurately detecting that the garbage bin is full through an openable and closable detection device, the garbage bags 31 are automatically packed and placed in a pre-set location by the system. That is, after the garbage is packed and placed in a designated location through the present invention, the cleaning staff can regularly transport the packed garbage away, thereby improving the cleaning efficiency. At the same time, the cleaning vehicle of the present invention does not have the bulky lifting transmission structure required for traditional garbage disposal, nor does it have the ineffective space required for lifting, which greatly increases the capacity of the garbage bin. At the same time, the present invention uses disposable garbage bags 31 to effectively isolate the garbage from the garbage bin of the cleaning vehicle, making the garbage bin cleaner and reducing the trouble of manually cleaning stuck garbage. The present invention also does not require the garbage to be crushed, which is beneficial for subsequent garbage classification and environmental protection. For example, in actual applications, the present invention can place about fifty garbage bags 31 at a time, which can basically meet the cleaning tasks of a day in most scenarios.

[0091] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
