Description

Technical Field

[0001] The utility model relates to the field of garden maintenance machinery, in particular to a garden cleaning robot system. Background Art

[0002] The garden cleaning robot system of the present invention comprises a leaf collecting robot and a collecting device independent of the leaf collecting robot. The leaf collecting robot is used to collect leaves, and the collecting device stores the leaves.

[0003] Garden cleaning robots are known and are designed to help people clean fallen leaves in their gardens easily and efficiently. These machines are usually equipped with sensors and navigation systems, and can move autonomously in the garden and complete cleaning tasks. However, existing garden leaf-collecting equipment still has some technical defects. For example, after some garden cleaning robots collect fallen leaves, they pile them in a fixed location in an open environment, which requires manual processing in a timely manner. Otherwise, the piled leaves are easily affected by the external weather and cause them to fly or rot, making cleaning more difficult. In addition, some garden cleaning robots store leaves in their own leaf collection box throughout the leaf collection process. As the cleaning process progresses, the weight of the leaf collection box doubles, which can easily increase the load on the machine, increase energy consumption, require more frequent charging of the equipment, have poor endurance, or require the use of a larger capacity battery, which is not conducive to lightweighting and energy saving.

[0004] With the development of technology, collection devices with induction switch functions have gradually emerged. For example, the top cover of the collection device is automatically opened by a motor and a transmission part. The single-sided meshing gear drives the other side to rotate, and the opening and closing is not smooth. The other side is easy to loosen after long-term use, which hinders the stable operation of the self-energy collection device. Utility Model Content

[0062] In the following description, in order to clearly demonstrate the structure and working mode of the present invention, many directional words will be used for description, but words such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and should not be understood as restrictive terms.

[0063] Unless otherwise defined or indicated, all professional and scientific terms used herein have the same meaning as those familiar to those skilled in the art. In addition, any methods and materials similar or equivalent to those described herein can be applied to the methods of the present invention.

[0064] The courtyard cleaning robot system of the present invention includes a leaf collecting robot and a collection system independent of the leaf collecting robot. The leaf collecting robot is used to collect leaves, and the collection system stores leaves. The leaf collecting robot transports the collected leaves to the collection system for unified storage. After the existing automatic leaf collecting machines or leaf collecting robots collect the leaves, they are mainly unloaded and piled at a fixed position in an open environment, and then cleaned manually. This mode is easily affected by the environmental weather. For example, the piled leaves on windy days are easy to fly away, which may contaminate the cleaned area and need to be cleaned again. On rainy days, the leaves will be soaked and watered, which will increase the difficulty of manual cleaning. If the leaves are not cleaned in time in humid climates, they will also produce a rotten odor. The closed collection system storage environment in the present invention can solve these problems.

[0065] The leaf-collecting robot includes a robot body, an energy source, a mobile mechanism, a leaf-collecting mechanism, a charging docking mechanism, and a first leaf-transferring docking mechanism. The energy source, mobile mechanism, leaf-collecting mechanism, charging docking mechanism, and first leaf-transferring docking mechanism are all carried by the robot body. The energy source is preferably a rechargeable battery pack. The mobile mechanism is preferably a wheel. The leaf-collecting mechanism includes a leaf picker and a first leaf storage device. The leaf picker is preferably a roller brush or leaf vacuum. The charging docking mechanism includes a pair of charging electrodes.

[0066] The collection system includes a collection system body, a power supply mechanism, a first fallen leaf processing mechanism, a power supply docking mechanism, and a second fallen leaf transfer docking mechanism. The power supply mechanism, the first fallen leaf processing mechanism, and the power supply docking mechanism are all carried by the collection system body. The power supply mechanism includes a power cord connected to the city power grid. The power supply docking mechanism is preferably electrically connected to the charging docking mechanism. The first fallen leaf processing mechanism includes at least one of a fallen leaf compacting device, a fallen leaf crushing device, and a fallen leaf incineration device. The second fallen leaf transfer docking mechanism can cooperate with the first fallen leaf transfer docking mechanism to form a fallen leaf transfer channel.

[0067] The robotic yard cleaning system also includes a fallen leaf transfer mechanism, which can be provided on the leaf collecting robot, on the collection system, or partially on the leaf collecting robot and partially on the collection system. The fallen leaf transfer mechanism includes at least one of a blowing device, a suction device, and a pushing device.

[0068] In some embodiments, the fallen leaf transfer mechanism transfers the fallen leaves in the first fallen leaf storage to the first fallen leaf processing mechanism, and the first fallen leaf processing mechanism performs at least one of compacting, crushing, and incinerating the fallen leaves.

[0069] In some embodiments, the collection system further includes a second leaf storage, and the leaf transfer mechanism is configured to transfer leaves from the first leaf storage to the second leaf storage. The second leaf storage is equipped with a sensing device, such as a camera or a weighing sensor. When the leaves in the second leaf storage reach a predetermined height or weight, the first leaf processing mechanism performs at least one of compacting, crushing, and incinerating the leaves.

[0070] In some embodiments, the collection system is also provided with a packing mechanism, which cooperates with a sensor device, such as a camera or a weighing sensor. When the leaves collected by the collection system reach a preset height or a preset weight, the packing mechanism is automatically packed or fed back to the upper terminal to prompt the user to process. The packing mechanism can be a packing mechanism with automatic sealing, such as using garbage bags to store leaves in the collection system, and the packing mechanism uses heating wire to contact the bag opening to perform hot melt sealing, etc.

[0071] In some embodiments, the leaf collecting robot further includes a second fallen leaf processing mechanism. Preferably, the second fallen leaf processing mechanism is linked to the fallen leaf picking mechanism to perform preliminary processing on the picked up fallen leaves. A two-stage fallen leaf processing mechanism is set in the automatic leaf collecting system. The second fallen leaf processing mechanism on the leaf collecting robot performs rough processing on the fallen leaves, and the first fallen leaf processing mechanism on the collection system performs fine processing on the rough-processed fallen leaves. This can improve the fallen leaf processing effect, increase the fallen leaf storage capacity of the leaf collecting robot and the leaf storage on the collection system, and thus increase the continuous working time of the courtyard cleaning robot and reduce the frequency of human intervention. Further preferably, the power of the second fallen leaf processing mechanism is less than the power of the first fallen leaf processing mechanism. Setting low-power electrical appliances on the leaf collecting robot using a rechargeable battery pack and setting high-power electrical appliances on the collection system powered by the city power grid can help reduce the power consumption of the leaf collecting robot, increase the continuous working time, and improve the efficiency of leaf collecting. Of course, in some embodiments, the fallen leaf processing mechanism is only set on the collection system, which can also achieve the effects of reducing the power consumption of the leaf collection robot, increasing the working time of the leaf collection robot, reducing the number of times the leaf collection robot returns to charge, and reducing working noise.

[0072] In this embodiment, a leaf collecting robot roams within a user-designated area of ​​a courtyard and collects fallen leaves. When the first leaf storage is full or nearly full, the leaf collecting robot automatically returns to the vicinity of the collection system and docks with it. The leaf collecting robot is determined to have successfully docked with the collection system when the charging docking structure of the leaf collecting robot forms a stable electrical connection with the power supply docking structure of the collection system, and the first leaf transfer docking mechanism and the second leaf transfer docking mechanism form a stable leaf transfer path. After the leaf collecting robot successfully docks with the collection system, the leaf collecting robot charges through the collection system, while the leaf transfer mechanism transfers leaves stored in the first leaf storage to the first leaf processing mechanism or the second leaf storage. When the first leaf processing mechanism is empty and the leaf collecting robot is suitable for continued operation (e.g., the remaining battery level is above a threshold or within the permitted operating time range), the leaf collecting robot leaves the collection system and enters the operating area to continue collecting leaves. When the leaf collecting robot is unsuitable for continued operation (e.g., the remaining battery level is below a threshold or within the non-operating time range), the leaf collecting robot remains docked with the collection system, preferably maintaining only the charging electrical connection and disconnecting the leaf transfer path. The first fallen leaf processing mechanism on the collection system compacts, crushes and / or incinerates the fallen leaves, places the residue into a collection bag, packs it when the packing conditions are met, and transports the packed fallen leaf residue to a designated location to wait for user processing. At the same time, a new collection bag is connected to the first fallen leaf processing mechanism, waiting for subsequent discharge of fallen leaf residue.

[0073] The present invention controls the overall power of the leaf collecting robot and limits it to a fixed range, thereby reducing the energy consumption of the machine through the reasonable allocation of functional mechanisms. Functional mechanisms such as the crushing mechanism, compression mechanism and packaging mechanism with excessively high working power are placed on the collection system, while those with low power are placed on the leaf collecting robot.

[0074] The following is a detailed description of the main body of the collection system of the garden cleaning robot system 100 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0075] like Figure 1-7 As shown, the main body of the collection system includes 100, including a collection barrel 1 and an air extraction mechanism 2. The collection barrel 1 includes a barrel body 11, a rear cover 14 connected to the rear side of the barrel body 11, a flip cover 12 installed on the top of the barrel body 11, and an upper cover 13 connected to the top surface of the flip cover 12. The barrel body 11 includes a side wall 111 formed around a vertical axis and a bottom wall 112 connected to the bottom end of the side wall 111. The barrel body 11 is used to accommodate a collection bag, which is generally a garbage bag, but can also be other plastic bags, which will be replaced by a garbage bag hereinafter. The flip cover 12 is flippably connected to the top surface of the barrel body 11, and a garbage bag is installed in the flip cover 12. The garbage bag is a garbage bag without breakpoints.

[0076] The packaging mechanism includes a sealing device 3 and a binding device 4, wherein the sealing device 3 and the binding device 4 are respectively installed in the flip cover 12. When the garbage bag is full of garbage, the binding device 4 can gather the top of the garbage bag to the sealing device 3. The sealing device 3 heat-seals the top of the garbage bag and then melts it. The flip cover 12 is opened and the garbage bag in the barrel body 11 can be taken out.

[0077] The garbage bag without breakpoints is in a continuous cylindrical shape and can be cut into multiple garbage bags after the sealing device 3 is melted. Moreover, after each melting, the top end of the old garbage bag is sealed and the bottom end of the new garbage bag is sealed at the same time.

[0078] One end of the collecting barrel 1 along the first direction is defined as the front end 101. Figure 1 As shown, the other end is the rear end 102, the second direction is the left and right direction of the collecting barrel 1, and the second direction is perpendicular to the first direction.

[0079] An air outlet 113 is provided on the rear side of the barrel body 11 , that is, an air outlet 113 is provided behind the side wall 111 of the barrel body 11 . The air outlet 113 is located near the bottom end of the side wall 111 and opens toward the interior of the accommodating space 15 .

[0080] The exhaust mechanism 2 is connected to the rear side of the side wall 111. After the old garbage bag is removed, the exhaust mechanism 2 extracts the air in the barrel body 11 from the air outlet 113, thereby forming a negative pressure in the barrel body 11, thereby sucking the new garbage bag into the barrel body 11 and spreading it out under the negative pressure, filling the collection barrel 1.

[0081] The upper cover 13 is connected to the rear side of the flip cover 12 in a flip-up manner. When the upper cover 13 is opened, garbage can be put into a garbage bag.

[0082] The rear cover 14 covers the rear side of the barrel body 11 and forms a receiving space 15 with the rear side of the barrel body 11. The receiving space 15 can be used to accommodate the exhaust mechanism 2 and the driving parts and circuit lines that drive the flip cover 12 to flip.

[0083] like Figure 2-6 As shown, the air extraction mechanism 2 is located in the accommodation space 15 formed by the rear cover 14 and the barrel body 11. The air extraction mechanism 2 is not visible from the outside and does not affect the overall appearance. Of course, in other embodiments, the air extraction mechanism 2 can also be directly installed on the outside of the barrel body 11.

[0084] The exhaust mechanism 2 includes a guide plate 21 and an exhaust device, wherein the guide plate 21 is an internally conductive ring and has a first end 211 and a second end 212, wherein the first end 211 is connected to the outside of the barrel body 11 and surrounds the air outlet 113 of the barrel body 11, and the second end 212 is the end away from the air outlet 113.

[0085] The opening size of the first end 211 is larger than the opening size of the second end 212. The shape of the guide plate 21 is approximately bowl-shaped. The diameter of the contact surface between the first end 211 and the gas outlet 113 is the largest, the air extraction area is large, and the internal transition is smooth, which is conducive to gas guidance and improves the air extraction efficiency.

[0086] The exhaust device is connected to the barrel body 11 or the guide plate 21, and the exhaust device includes a bracket 22, a driving member and a fan 24, wherein the bracket 22 is connected to the barrel body 11 or the guide plate 21, and the driving member is connected to the bracket 22. The driving member is defined as a first driving member 23, and the first driving member 23 is a motor.

[0087] The fan 24 is mounted on a side of the bracket 22 near the deflector 21 and is connected to the first drive member 23. The fan is aligned with the second end 212 of the deflector 21. When the first drive member 23 is activated, it drives the fan 24 to rotate, creating a negative pressure in the barrel 11. The air in the barrel 11 is then discharged through the air outlet 113 and the deflector 21.

[0088] As a preferred embodiment, the guide plate 21 is annular and extends around a horizontal axis, and the vertical distance between the inner wall of the guide plate 21 and the horizontal axis gradually increases from the second end 212 to the first end 211. In other words, the inner wall of the guide plate 21 gradually increases from the second end 212 to the first end 211, which is conducive to gas guidance. In other embodiments, the guide plate 21 can also be annular and tilted downward or upward, that is, the center line of the guide plate 21 can also be a curve, and the second end 212 can be located below or above the first end 211. The center of the second end 212 and the center of the first end 211 do not overlap, but the opening size of the second end 212 is also set to be smaller than the opening size of the first end 211.

[0089] As a preferred solution, the inner wall of the guide plate 21 is a smooth arc surface, the cross section of the guide plate 21 along the vertical direction is circular, and the guide plate 21 as a whole looks like a bowl, which can further improve the gas flow performance.

[0090] Preferably, the guide plate 21 is sealed to the barrel body 11 to improve the air extraction efficiency.

[0091] In one embodiment, an annular mounting groove 116 extending around the air outlet 113 is provided on the outer side of the barrel body 11 , and a sealing ring is provided in the annular mounting groove 116 . The first end 211 of the guide plate 21 abuts against the sealing ring to form a sealed connection with the barrel body 11 .

[0092] exist Figure 3In the illustrated embodiment, the rear door of the barrel body 11 is provided with an annular ridge 115, which extends around the air outlet 113 to form an annular shape, and an annular mounting groove 116 is formed by a depression in the annular ridge 115. In other embodiments, the annular mounting groove 116 may also be formed by a depression in the rear side surface of the barrel body 11. In another embodiment, the annular mounting groove 116 is formed by a depression in the cross section of the first end 211 of the deflector 21, and the annular ridge 115 provided on the outside of the barrel body 11 abuts against the sealing ring in the annular mounting groove 116.

[0093] Optionally, the garden cleaning robot system 100 further includes a mounting plate 25, which is connected to the second end 212 of the guide plate 21. The mounting plate 25 is plate-shaped and is arranged around the second end 212 of the guide plate 21. It is integrally formed with the guide plate 21, and a plurality of protruding positioning columns 117 are provided on the rear side of the barrel body 11, and the positioning columns 117 are connected to the guide plate 21 by bolts.

[0094] exist Figure 3 In the embodiment shown, three protruding positioning posts 117 are provided on the rear side surface of the barrel body 11. The three positioning posts 117 are evenly arranged in a triangle around the air outlet 113. The outer peripheral surface of the positioning post 117 is provided with a ridge 1171, and along the axial direction of the positioning post 117, the length of the ridge 1171 is shorter than the length of the positioning post 117. The end face of the ridge facing away from the barrel body 11 is at a distance from the upper end of the positioning post 117. The length of this distance needs to ensure that the guide plate 21 can fully squeeze the sealing ring after installation without generating a gap, so as to ensure the sealing effect.

[0095] Each positioning column 117 is provided with a threaded hole at one end away from the barrel body 11, and the mounting plate 25 is a triangular plate and has three countersunk holes 251 corresponding to the threaded holes at the three corners, and the bracket 22 is a triangular frame and has three connecting holes at the three corners. The three connecting holes of the bracket 22 and the three countersunk holes 251 of the mounting plate 25 correspond one to one with the threaded holes of the three positioning columns 117, respectively. The mounting plate 25 and the bracket 22 can be fixedly connected to the positioning columns 117 by three bolts. The three-point positioning connection provides better installation stability. Of course, in other embodiments, multiple positioning columns 117 can also be provided to be fixedly connected to the mounting plate 25 and the bracket 22. The utility model does not limit the number of positioning columns 117 and the specific shapes of the mounting plate 25 and the bracket 22.

[0096] As a preferred embodiment, the air outlet 113 is a central hole with a grille 114 mounted on its inner wall. The grille 114 helps to disperse and extract the air evenly, reducing local concentration, improving the spread of the garbage bag, and preventing foreign matter in the barrel 11 from entering the fan 24, the first drive member 23, and other equipment. It should be understood that the above-mentioned exhaust mechanism 2 can also be installed at the bottom of some other trash cans, and is not limited to fully automatic trash cans.

[0097] The flip cover 12 is connected to the top of the barrel body 11 in a flip-up manner, and the rear end 102 of the flip cover 12 is connected to the top of the barrel body 11 in a flip-up manner. Figure 7-11 As shown, the flip cover 12 includes a side cover 121, a bottom cover 122, a receiving plate 123, and a top cover 124. The side cover 121 is annular and reversibly connected to the barrel body 11. The bottom cover 122 is plate-shaped and connected to the bottom end of the side cover 121. The receiving plate 123 is connected to the inner wall of the side cover 121 and is located above the bottom cover 122, i.e., spaced apart from the receiving plate 123 and the bottom cover 122.

[0098] The bottom cover 122 is further provided with a first injection port 1221. Figure 10 As shown, the receiving plate 123 is provided with a second delivery port 1231. Figure 7 As shown, the second delivery port 1231 is located above the first delivery port 1221. The top surface of the receiving plate 123 is provided with an annular placement groove 1232, which is located above the first delivery port 1221 and the second delivery port 1231. The second delivery port 1231 and the first delivery port 1221 are both used to avoid the collection bag. The top cover 124 can be connected to the top surface of the receiving plate 123 in a flip manner, or connected to the top surface of the side cover 121, as shown in FIG. Figure 7-8 As shown, the top cover 124 is used to cover the placement slot 1232 to facilitate the replacement of garbage bags.

[0099] The garbage bag is looped within the placement groove 1232 and laid into the barrel body 11 from the second delivery port 1231 and the first delivery port 1221. The sealing device 3 is installed on the bottom surface of the receiving plate 123, and the cinch device 4 is installed between the receiving plate 123 and the bottom cover 122. The cinch device 4 gathers the top of the old garbage bag toward the sealing device 3, which then melts it. The exhaust mechanism 2 can then draw new garbage bags into the barrel body 11 from the second delivery port 1231 and the first delivery port 1221 and spread them out.

[0100] The sealing device 3 is connected to the rear side of the flip cover 12 along the first direction, as shown in FIG. Figure 10 、 Figure 13 and Figure 14 As shown, it is specifically installed at the rear bottom of the receiving plate 123 and is closer to the rear end 102 relative to the first injection port 1221 .

[0101] The sealing device 3 includes a base plate 31, a heating element 32, and a cover plate 33. The base plate 31 is connected to the bottom surface of the receiving plate 123. A press groove 312 is provided on the bottom surface of the base plate 31. The outer side surface of the base plate 31 is provided with an annular wiring groove 311. The wiring groove 311 passes through the press groove 312, that is, the wiring groove 311 is connected to the press groove 312. In the embodiment shown in the figure, the wiring groove surrounds three sides of the base plate 31 and does not form a ring. The wiring groove 311 passes through both ends of the base plate 31 and is connected to the press groove 312. The cover plate 33 in the press groove abuts against the portion of the heating element 32.

[0102] The heating element 32 utilizes a heating wire, which includes a heating component and a circuit connection portion. The heating component is used to heat-seal the garbage bag, while the circuit connection portion is used to energize the heating wire. The heating wire loop is positioned within the wiring groove 311 and passes through the pressure groove 312. The cover plate 33 is positioned within the pressure groove 312 and abuts the heating wire.

[0103] During installation, the heating wire is wound around the wiring groove 311 of the base plate 31, and the cover plate 33 is pressed into the pressing groove 312 and fixed to the base plate 31 via bolts. After the sealing device 3 is assembled as a whole, it is then bolted to the bottom surface of the receiving plate 123. This integrated installation method is relatively simple and suitable for use in mass production, which helps to improve production efficiency and reduce labor costs.

[0104] The base plate 31 is provided with a plurality of assembly holes 313. After the cover plate 33 is installed in the pressing groove 312, it can be fixedly connected to the assembly holes 313 by bolts. In other embodiments, the cover plate 33 can also be connected to the base plate 31 by snap fastening or bonding.

[0105] The cover plate 33 and the base plate 31 are respectively provided with mounting holes 331 aligned with each other, and the bottom surface of the receiving plate 123 is provided with a connecting column 1233 installed in the mounting holes 331 of the cover plate 33 and the base plate 31. The cover plate 33 and the base plate 31 can be connected to the connecting column of the receiving plate 123 by bolts.

[0106] The top surface of the cover plate 33 is provided with a pressing surface 332 at each end. The pressing surface 332 is formed by a depression in the top surface of the cover plate 33 and abuts against the heating portion 32. The pressing surface 332 is lower than its adjacent surface. This height difference ensures that the pressing surface 332 on the cover plate 33 can press the heating wire tightly without causing excessive compression damage to the heating wire, thereby improving heating efficiency and preventing the heating wire from loosening or shifting during use.

[0107] The constricting device 4 is connected to the top surface of the bottom cover 122, as shown in FIG. Figure 11 and Figure 13 As shown, it is used to gather the collection bags to the sealing device 3.

[0108] The cinch device 4 includes two clamping plates 41 , a pressure rod 42 and a driving member, which is defined as a second driving member 43 .

[0109] The two clamping plates 41 are located on one side of the sealing device 3 along the second direction and are movably connected to the top surface of the bottom cover 122. In other words, the clamping plates 41 are located on the left and right sides of the sealing device 3 and can move left and right. Figure 7 and Figure 8 In the illustrated embodiment, the two clamping plates 41 are movably connected to the bottom cover 122 via screws 44. The screws 44 extend along the second direction and are fixedly connected to the bottom cover 122. The two clamping plates 41 are respectively connected to the screws 44. In other embodiments, the two clamping plates 41 may also be movably connected to the bottom cover 122 via rails.

[0110] The pressing rod 42 is connected to the top surface of the bottom cover 122 and is closer to the front end 101 than the first injection port 1221 .

[0111] The second driving member 43 is connected to the pressure rod 42 and can drive the pressure rod 42 to drive the clamping plate 41 to switch between the gathered state and the disengaged state;

[0112] In the gathered state, the pressure rod 42 and the clamping plate 41 respectively squeeze the garbage bag towards the sealing device 3. In the disengaged state, the pressure rod 42 and the clamping plate 41 are respectively away from the sealing device 3, and the pressure rod 42 is located at the front end of the first delivery port 1221, that is, it and the sealing device 3 are located on the two rear sides of the garbage bag.

[0113] In a specific embodiment, the two clamping plates 41 are each provided with a slide groove 411, which extends in a direction intersecting the first direction and the second direction, respectively. The slide groove 411 has an open front end and gradually deviates from the sealing device 3 from the back to the front. The pressure rod 42 is provided with a push rod 421 on the side facing the sealing device 3, that is, the push rod 421 is provided on the rear side of the pressure rod 42, and a protruding slider is provided at the bottom of the rear end of the push rod 421.

[0114] The second driving member 43 is a motor connected to a gear. Two racks 47 extending in the first direction are also provided on the top surface of the top cover 124. The second driving member 43 is mounted on the compression rod 42, and the output shaft of the second driving member 43 is connected to a gear. This gear and one of the racks 47 cooperate to drive the compression rod 42. Another gear is connected to the compression rod 42 and cooperates with the other rack 47. Alternatively, a configuration may be employed in which one second driving member 43 drives one gear and rack 47 to drive the compression rod 42, while another pulley and rail cooperate to support the movement of the compression rod 42.

[0115] As a preferred solution, Figure 9 and Figure 10As shown, two second driving members 43 are respectively connected to the pressure rod 42, and the two second driving members 43 are respectively connected to two gears, which are respectively engaged with two racks 47 and drive the pressure rod 42 to move. In other embodiments, the second driving member 43 can also be configured as a cylinder and a telescopic rod, or as a chain sprocket, etc. The present invention does not limit the specific operation method of the movement of the pressure rod 42.

[0116] When the pressure rod 42 is in the disengaged state, Figure 9 As shown, it is located at the front side of the bottom cover 122. At this time, the slider is out of the slide groove 411 and aligned with the front end opening of the slide groove 411. When the garbage bag needs to be heat-sealed, the second driving member 43 can drive the pressure rod 42 to move toward the rear side. When the pressure rod 42 moves to the slide groove 411, the slider of the push rod 421 enters the slide groove 411 and slides in the slide groove 411, thereby driving the clamping plate 41 to move toward the sealing device 3, thereby pushing the top end of the garbage bag to gather at the sealing device 3. When the clamping plate 41 and the pressure rod 42 slide to the gathered state, as shown in FIG. Figure 10 As shown, the slider is located at the rear end of the slide groove 411, and the garbage bags are gathered at the sealing device 3.

[0117] It should be noted that when the pressure rod 42 and the clamping plate 41 are in the converged state, the motor of the second drive member 43 rotates in reverse, and the slider retracts a short distance in the chute 411, without sliding out of the chute 411. The pressure rod 42 drives the clamping plate 41 away from the sealing device 3. At this time, the opening of the garbage bag is still stuck to the heat-scalding structure and cannot be broken or separated. The motor rotates forward again, and the slider moves backward in the chute 411 again. The pressure rod 42 drives the clamping plate 41 to squeeze the garbage bag towards the sealing device 3 again, and the garbage bag is completely cut off by the heat-scalding structure and falls into the bucket.

[0118] In existing technologies, if you want to seal and fuse the garbage bag in one action, you need a higher heat temperature, which may cause the garbage bag to produce odor during the heat melting process. Alternatively, the existing technology uses a blade to cut the garbage bag, which requires a telescopic structure to control the blade, making the structure more complicated. However, the present invention has an additional retracting action and a reciprocating action to fuse the bag opening, which can ensure that the garbage bag is melted without sticking at a lower heat temperature.

[0119] In addition, the present invention uses only one motor on one side, and the splint 41 is driven by the pressure rod 42 mechanically, which reduces costs and energy consumption. The number of electronic control components such as motors and micro switches is relatively small, thereby reducing potential failure points, improving the stability and reliability of the constricting device 4, and simplifying the programming and debugging process.

[0120] It should be understood that in other embodiments, the splint 41 can be one, and the push rod 421 and the slider are also set as one respectively. To match this splint 41, the sealing device 3 can be set at a corner of the first delivery port 1221, and the pressure plate drives the splint 41 to squeeze the garbage bag toward the sealing device 3 to tighten the mouth.

[0121] Optionally, the garden cleaning robot system 100 further includes two guide rods 45, which extend along a first direction and are connected to the top surface of the bottom cover 122 or the bottom of the receiving plate 123. A plurality of guide rollers 46 are provided on the pressure rod 42, and the plurality of guide rollers 46 are respectively connected to the guide rods 45 for rolling connection.

[0122] The rear side of the flip cover 12 along the first direction is driven by another driving member to be flipably connected to the barrel body 11 . The driving member is defined as a third driving member 55 , and the third driving member 55 is connected to the barrel body 11 .

[0123] In addition, the barrel body 11 is also provided with a first gear 51, a second gear 52, a third gear 53, a transmission shaft and a positioning assembly 5, as shown in FIG. Figure 16 and Figure 17 As shown, the first gear 51 is connected to the output shaft of the driving member. The transmission shaft is the first transmission shaft 54, and one end of the first transmission shaft 54 ​​is connected to the barrel body 11. The positioning assembly 5 is connected to the barrel body 11 and is provided with a mounting hole for fixing the other end of the first transmission shaft 54, that is, the other end of the first transmission shaft 54 ​​is fixed to the barrel body 11 through the positioning assembly 5. The second gear 52 is sleeved on the outside of the first transmission shaft 54 ​​and meshes with the first gear 51. The third gear 53 is connected to the flip cover 12 and meshes with the second gear 52. The third driving member 55 is a motor. After the third driving member 55 is started, the flip cover 12 can be driven to rotate through the transmission of the first gear 51, the second gear 52 and the third gear 53. Fixing the first transmission shaft 54 ​​by the positioning assembly 5 can prevent the third driving member 55 from jumping when driving the second gear 52 to rotate.

[0124] In one embodiment, a gear box 56 is provided on the barrel body 11. A portion of the gear box 56 is located within the accommodating space 15 formed by the rear cover 14 and the barrel body 11, and the top end of the gear box 56 extends beyond the top surface of the barrel body 11. The gear box 56 is fixedly connected to the barrel body 11 and is used to mount the third driving member 55, the first gear 51, the second gear 52, and the third gear 53. In other words, the third driving member 55, the first gear 51, the second gear 52, and the third gear 53 are fixedly connected to the barrel body 11 via the gear box 56. It should be understood that in other embodiments, the third driving member 55, the first gear 51, the second gear 52, and the third gear 53 can also be directly mounted on the barrel body 11.

[0125] In the present invention, the first gear 51 , the second gear 52 and the third gear 53 are respectively installed in the gear box 56 , while the third driving member 55 is installed outside the gear box 56 to facilitate maintenance of the third driving member 55 .

[0126] The positioning assembly 5 includes a connecting plate 57, a positioning member 58, and an abutment plate 59. The connecting plate 57 is connected to or integrally formed with the gearbox 56. The positioning member 58 includes a positioning plate 581 and a side plate 582. The positioning plate 581 is connected to one end of the connecting plate 57 and is joined with the end of the connecting plate 57 to form a mounting hole for mounting the first transmission shaft 54. The positioning plate 581 and the connecting plate 57 are each grooved to form a semicircular hole, and the two semicircular holes are joined to form the mounting hole. The end of the connecting plate 57 is also provided with two threaded holes, located above and below the mounting hole. The positioning plate 581 can be connected to the threaded holes of the connecting plate 57 via two bolts.

[0127] The side plate 582 is located on the side of the connecting plate 57 facing away from the second gear 52 and abuts against the connecting plate 57. The side plate 582 can support the connecting plate 57 to enhance the stability of the first transmission shaft 54. The shape of the side plate 582 is preferably complementary to the shape of the side of the connecting plate 57 facing away from the second gear 52 to provide better support.

[0128] Because the connecting plate 57 is provided with threaded holes, its side facing away from the second gear 52 has two protruding curved surfaces. The side plate 582 mates with the side of the connecting plate 57 facing away from the second gear 52, so the side plate 582 also has two curved surfaces that protrude away from the connecting plate 57, forming a recessed abutment groove 583 between the two curved surfaces. The abutment plate 59 consists of two parts: one is flat, with its end located within the abutment groove 583 and abutting against the inner wall of the abutment groove 583; the other part extends up and down along the two curved surfaces of the side plate 582 to form an arcuate strip, which mates with the portion of the side plate 582 facing away from the connecting plate 57, further enhancing the stability of the first transmission shaft 54.

[0129] The abutment plate 59 is preferably connected to the gear box 56 or formed integrally therewith. The abutment plate 59 abuts against the side of the side plate 582 away from the second gear 52. The abutment plate 59 cooperates with the side plate 582 to enhance the stability of the first transmission shaft 54 ​​and prevent the first transmission shaft 54 ​​from jumping.

[0130] It should be understood that in other embodiments, the third driving member 55, the first gear 51, the second gear 52 and the third gear 53 are directly mounted on the barrel body 11. The connecting plate 57 and the abutting plate 59 of the positioning assembly 5 are integrally formed with the barrel body 11.

[0131] The upper cover 13 is connected to the flip cover 12 through the driving assembly 6. Figure 18-21As shown, two half gears 131 are provided on the rear side of the upper cover 13 along the first direction, and the two half gears 131 are spaced apart and arranged side by side along the second direction. It should be understood that in other embodiments, two or more gears can also be fixedly mounted on the rear side of the upper cover 13, but the half gears are preferred because the gears occupy more space.

[0132] The drive assembly 6 is connected to the flip cover 12 and includes a drive member and two transmission gears 62. The drive member is defined as a fourth drive member 61, which is also a motor. The two transmission gears 62 can be driven by the fourth drive member 61 and mesh with the two half gears 131 of the upper cover 13. When the fourth drive member 61 is activated, it can drive the two transmission gears 62 to rotate and drive the upper cover 13 to flip between the closed state and the open state.

[0133] In the closed state, the upper cover 13 covers the top surface of the flip cover 12 to prevent the odor from escaping from the barrel 11. In the open state, the upper cover 13 is opened and garbage can be thrown into the garbage bag in the barrel 11.

[0134] The driving assembly 6 is connected to the flip cover 12 of the collecting bucket 1 and includes a driving member and at least two transmission gears 62 . The driving member is defined as a fourth driving member 61 . The fourth driving member 61 is connected to the flip cover 12 .

Alternatively, in some embodiments, the collection barrel 1 does not have a flip cover 12, and the second transmission shaft 63 can be directly fixedly connected to the barrel body 11 of the collection barrel 1, with the upper cover 13 being reversibly connected to the barrel body 11 via the drive assembly 6.

[0137] The two transmission gears 62 are respectively installed at the two ends of the second transmission shaft 63 along the second direction. The fourth driving member 61 is connected to the receiving plate 123 or the transmission shaft of the flip cover 12. The fourth driving member 61 can be directly connected to one of the transmission gears 62 and drive the transmission gear 62 to rotate through the transmission shaft.

[0138] In the preferred embodiment shown in the figure, the fourth driving member 61 is connected to the second transmission shaft 63 through the seat body 65. The seat body 65 is installed on the second transmission shaft 63, which can save the internal space occupied by the seat body 65 and the fourth driving member 61. The output shaft of the fourth driving member 61 is connected to a gear, which is engaged with one of the transmission gears 62. The transmission gear 62 is driven to rotate through the gear, thereby driving the second transmission shaft 63 to drive the other transmission gear 62 to rotate.

[0139] It should be understood that in other embodiments, more transmission gears 62 may be provided on the second transmission shaft 63, and more half gears 131 may be provided on the bottom surface of the upper cover 13. The multiple half gears 131 are rotatably connected to the multiple transmission gears 62 via the rotating shaft 66 and respectively mesh with the multiple transmission gears 62. The fourth driving member 61 can simply drive one of the transmission gears 62 to rotate.

[0140] The two mounting blocks 64 are also each mounted with a rotating shaft 66 extending in the second direction, with the axes of the two rotating shafts 66 overlapping. The two half gears 131 are each provided with an axial hole that fits over the two rotating shafts 66, and the two half gears 131 rotate around the two rotating shafts 66. It should be understood that in some embodiments, the two half gears 131 can also be mounted on the same rotating shaft 66, with both ends of the rotating shaft 66 connected to the side cover 121 of the flip cover 12 or to the two mounting blocks 64.

[0142] The accommodating groove 1234 is located at the rear side of the avoiding groove 1235 and is communicated with the avoiding groove 1235 . When the upper cover 13 is in the open state, the rear side of the upper cover 13 is located in the accommodating groove 1234 .

[0143] In some other embodiments, the receiving groove 1234 may not be provided, and when the upper cover 13 is opened, the rear side of the upper cover 13 may be flipped to the rear side of the flip cover 12 .

[0144] It should be understood that in some embodiments, the upper end of the barrel body 11 is not provided with a flip cover 12, that is, when the collection barrel 1 only includes the barrel body 11 and the upper cover 13, the sealing device 3 and the constricting device 4 of the present invention can also be directly provided on the upper end of the side wall 111 of the barrel body 11, and the upper cover 13 can also be directly connected to the upper end of the side wall 111 in a flip-up manner.
