[0026] In an optional embodiment, the bottom of the pressure bucket frame is hinged to the bottom of the tipping bucket frame; the garbage bin is at least partially made of a flexible material;

[0027] The feeding mechanism also includes a telescopic drive component, the two ends of which are respectively hinged to the tipping frame and the pressing frame, for driving the pressing frame to rotate relative to the tipping frame, so as to increase or decrease the distance between the top of the pressing frame and the top of the tipping frame, thereby causing the garbage bin to unfold or fold.

[0028] In an optional embodiment, the garbage hopper includes a bottom wall and a left side wall, a front side wall, a right side wall, and a rear side wall connected to the bottom wall;

[0029] The left side wall, the front side wall, the right side wall, and the rear side wall are connected end to end in sequence;

[0041] The lifting mechanism of the bin-hanging frame works in conjunction with the bin-pressing frame to secure the trash can. The lifting arm can rotate the bin-tilting frame, bin-pressing frame, bin-hanging frame, and trash can together, enabling the loading and unloading of the trash can. Because a first sensor is installed on the bin-hanging frame and a second sensor on the bin-pressing frame, when a trash can is attached to the frame, the first sensor detects it, and the frame rises with the trash can until it is detected by the second sensor, at which point it stops. At this optimal height, the trash can is stably secured by the combined action of the hanging and pressing frames, thus automating the bin-hanging operation and improving efficiency.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0060] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0061] refer to Figure 1 This application discloses a feeding mechanism, which is mainly used in garbage trucks and can feed both standard garbage bins and bulk garbage.

[0062] The feeding mechanism includes a lifting arm 100, a drum tilting frame 200, a drum pressing frame 300, a drum hanging frame 400, a left support arm 500, and a right support arm 600.

[0063] The tipping frame 200 is fixed to the lifting arm 100. As the main frame of the entire feeding mechanism, the tipping frame 200 is an intermediate load-bearing structure connecting the lifting arm 100 and the pressing frame 300. It can be flipped under the drive of the lifting arm 100. In this way, the tipping frame 200 can carry the pressing frame 300, the hanging frame 400, the left support arm 500 and the right support arm 600 together with the lifting arm 100 to flip, thereby realizing the dumping operation of the garbage can.

[0064] The pressure rack 300 is fixed to the side of the tipping rack 200 away from the lifting arm 100. The pressure rack 300 is used to press down the top of the trash can to prevent the trash can from falling off or shaking during the tipping process.

[0065] The hanging bin rack 400 is height-adjustable and located on the side of the pressing bin rack 300 away from the flipping bin rack 200. The hanging bin rack 400 is used to hang standard garbage bins and has the ability to be adjusted up and down to adapt to garbage bins of different sizes, so as to realize the hanging and positioning of garbage bins.

[0066] The left support arm 500 and the right support arm 600 are both hinged to the side of the bin rack 400 away from the bin rack 400, and are used to support the hanging lugs of the garbage bin, and work with the bin pressing frame 300 to achieve stable fixation of the garbage bin.

[0067] During the actual loading of the garbage bin, the garbage truck first approaches the standard garbage bin, then the bin-hanging frame 400 lowers, and the left support arm 500 and right support arm 600 extend to align with the hanging lugs on both sides of the garbage bin; then the garbage bin is hooked onto the bin-hanging frame 400, and the bin-hanging frame 400 rises, causing the left support arm 500 and right support arm 600 to simultaneously lift the hanging lugs, while the top of the garbage bin abuts against the pressure frame 300, thus fixing the garbage bin in place and achieving the bin-hanging operation; then the lifting arm 100 drives the tipping frame 200, pressure frame 300, bin-hanging frame 400, left support arm 500, right support arm 600, and garbage bin to be lifted and tilted together, raising the garbage bin; after the lifting arm 100 continues to tilt to the highest point, the garbage bin can be inverted, and the garbage will slide out of the garbage bin due to its own weight, thus falling into the garbage container.

[0068] It should be noted that while traditional feeding mechanisms can feed standard garbage bins, they are not suitable for feeding loose garbage such as bagged garbage. In such cases, loose garbage needs to be manually poured into the garbage bins, which is time-consuming and labor-intensive.

[0069] Therefore, in this embodiment, reference is made to Figure 1 and Figure 2 The feeding mechanism also includes a garbage hopper 700, which is sandwiched between the tipping frame 200 and the pressing frame 300. The sides of the pressing frame 300 and the tipping frame 200 that are close to each other are connected to the side wall of the garbage hopper 700. The garbage hopper 700 is used to hold bulk garbage.

[0070] In this way, the lifting and lowering of the bin-hanging frame 400, together with the bin-pressing frame 300, can secure the garbage bin. The lifting arm 100 can rotate the bin-tilting frame 200, the bin-pressing frame 300, the bin-hanging frame 400, and the garbage bin together, realizing the functions of loading and unloading garbage bins. Since a garbage hopper 700 is connected between the bin-pressing frame 300 and the bin-tilting frame 200 on their closest sides, the garbage hopper 700 can hold loose garbage. Therefore, loose garbage can be manually poured into the garbage hopper 700. As the lifting arm 100 rotates the bin-tilting frame 200, the functions of loading and unloading loose garbage in the garbage hopper 700 can also be realized. Therefore, this loading mechanism can simultaneously realize the loading and unloading functions of standard garbage bins and loose garbage, eliminating the need for manual dumping of loose garbage into garbage bins, saving manpower and resources.

[0071] In one embodiment, reference Figures 1 to 4The garbage bin 700 can be constructed using a combination of flexible and rigid materials, or solely of flexible materials. This means that at least a portion of the garbage bin 700 is made of flexible materials. This allows the garbage bin 700 to be unfolded when needed for bulk garbage and folded when not in use, reducing the structural volume of the feeding mechanism. At this time, the bottom of the pressure frame 300 is hinged to the bottom of the tipping frame 200. The feeding mechanism also includes a telescopic drive component 800, which can be a hydraulic cylinder, pneumatic cylinder, or electric actuator, etc. The two ends of the telescopic drive component 800 are respectively hinged to the tipping frame 200 and the pressure frame 300, driving the pressure frame 300 to rotate relative to the tipping frame 200, thereby increasing or decreasing the distance between the top of the pressure frame 300 and the top of the tipping frame 200, thus unfolding or folding the garbage bin 700.

[0072] In this way, when it is necessary to load or unload bulk waste, the extension of the telescopic drive component 800 increases the distance between the top of the pressure bucket frame 300 and the top of the tipping bucket frame 200, and the garbage hopper 700 unfolds accordingly, so that bulk waste can be poured into the garbage hopper 700. After the bulk waste is unloaded, the extension drive component 800 retracts, which reduces the distance between the top of the pressure bucket frame 300 and the top of the tipping bucket frame 200, and the garbage hopper 700 folds accordingly, so that standard garbage bins can be loaded and unloaded.

[0073] For more details, please refer to the following: Figure 3 and Figure 4 The garbage bin 700 includes a bottom wall 750 and a left side wall 710, a front side wall 720, a right side wall 730 and a rear side wall 740 connected to the bottom wall 750; the left side wall 710, the front side wall 720, the right side wall 730 and the rear side wall 740 are connected end to end in sequence; the front side wall 720 is connected to the bin pressing frame 300 and the rear side wall 740 is connected to the bin tipping frame 200; the left side wall 710 and the right side wall 730 are both made of flexible material.

[0074] Thus, both the left side wall 710 and the right side wall 730 are made of flexible materials. When the telescopic drive 800 retracts, the left side wall 710 and the right side wall 730 can gradually fold up to achieve the folding of the garbage bin 700; when the telescopic drive 800 extends, the left side wall 710 and the right side wall 730 can gradually unfold to achieve the unfolding of the garbage bin 700.

[0075] The front sidewall 720, rear sidewall 740, and bottom wall 750 can all be made of flexible materials. Using materials of similar properties reduces processing steps and facilitates the manufacturing of the garbage bin 700. The left sidewall 710, front sidewall 720, right sidewall 730, and rear sidewall 740 are sequentially connected via a heat-sealing process. All four sides are also connected to the bottom wall 750 via heat-sealing. This fuses adjacent sidewalls into a single unit, creating a strong, sealed, and seamless joint, thus ensuring the load-bearing capacity and service life of the entire garbage bin 700.

[0076] The flexible material can be canvas, but in some embodiments, the front sidewall 720 and the rear sidewall 740 can also be made of rigid material.

[0077] The front sidewall 720 is riveted to the pressure bucket frame 300 by pressure strips 770. All four edges of the front sidewall 720 are riveted to the pressure bucket frame 300 by pressure strips 770. The rear sidewall 740 is riveted to the tilting bucket frame 200 by pressure strips 770. All four edges of the rear sidewall 740 are riveted to the tilting bucket frame 200 by pressure strips 770, so as to ensure the reliability of the connection between the garbage bin 700 and the pressure bucket frame 300 and the tilting bucket frame 200 respectively.

[0078] The upper edges of the left side wall 710 and the right side wall 730 are both double-sealed. The double-sealing means that the upper edges of the left side wall 710 and the right side wall 730 are folded and then heat-sealed. The double-sealing can enhance the tear resistance of the upper edges, prevent the upper edges of the left and right side walls 730 from coming loose or breaking due to force or friction, and make the edges smoother and more beautiful.

[0079] The upper edge of the left side wall 710 and the upper edge of the right side wall 730 each have at least two double-layer sealing edges, with support columns 760 sealed inside the double-layer sealing edges. In this way, during the retraction of the telescopic drive component 800, the left side wall 710 and the right side wall 730 will fold along the gap between the two double-layer sealing edges, thus realizing the folding of the garbage bin 700. The support columns 760 can be made of steel pipes and act as a skeleton, providing rigidity and shape retention for the upper edges of the left and right side walls 730 of the garbage bin 700, preventing the garbage bin 700 from deforming and collapsing, and facilitating the dumping of bulk garbage.

[0080] In another embodiment, reference Figure 5 The garbage bin 700 can also be made of rigid materials such as metal or alloy. In this case, the garbage bin 700 is roughly a hollow cuboid structure. The tipping frame 200 can be directly made as the rear side wall 740 of the garbage bin 700, that is, the tipping frame 200 and the garbage bin 700 are connected as one piece. Alternatively, the tipping frame 200 can be separated from the garbage bin 700 and fixedly connected by welding or other methods. It is only necessary to leave an opening at the top for bulk garbage to be poured in.

[0081] It should be noted that the existing technology requires manual adjustment of the 400mm height of the bucket hanging frame, the success rate of hanging the bucket is highly dependent on the operator's experience, the work efficiency is low, and the operation is difficult.

[0082] Therefore, the feeding mechanism in one embodiment of this application further includes a bucket hanging frame 400, which is vertically and vertically mounted on the bucket pressing frame 300;

[0083] refer to Figures 6 to 9 The bin rack 400 is equipped with a first sensor 900. When the first sensor 900 senses the trash can, the bin rack 400 rises. The bin rack 400 is also equipped with a second sensor 910. During the rising process of the bin rack 400, when the second sensor 910 senses the bin rack 400, the bin rack 400 stops rising.

[0084] In this way, when the trash can is hung on the bin rack 400, the trash can will be detected by the first sensor 900, and the bin rack 400 can then lift the trash can up together until it is detected by the second sensor 910 and stops lifting. At this point, the height of the bin rack 400 is the optimal hanging height. The trash can is stably fixed by the combined action of the bin rack 400 and the bin pressing frame 300, thereby realizing automated bin hanging operation and improving efficiency.

[0085] It is understandable that the lifting and lowering of the hanging bucket rack 400 is achieved through a lifting drive, which can be a hydraulic cylinder or the like. The control of the lifting drive and the signal processing of the first sensor 900 and the second sensor 910 are achieved through a controller. That is, the first sensor 900 and the second sensor 910 trigger sensing signals and send them to the controller. The controller then controls the operation of the lifting drive based on the sensing signals from the first sensor 900 and the second sensor 910, thereby achieving the lifting and lowering of the hanging bucket rack 400.

[0086] The aforementioned controller is typically a central processing unit (CPU), which can be configured with a corresponding operating system and control interfaces. Specifically, it can be a microcontroller, DSP (Digital Signal Processing), ARM (Advanced RISC Machines), or other digital logic control unit capable of automated control. It can load control instructions into memory for storage and execution at any time. It can also have built-in CPU instruction and data memory, input / output units, power supply modules, digital and analog units, etc. The specific configuration can be determined according to the actual usage, and this application does not impose any limitations on this.

[0087] To ensure that the first sensor 900 accurately senses whether the trash can is hooked onto the trash can rack 400, in one embodiment, continuing to refer to... Figure 7 and Figure 9 The bucket rack 400 is provided with a fixed plate 930 and a sensor rod 940 that is movably provided on the fixed plate 930 on the side near the bucket pressing rack 300;

[0088] An elastic element 920 is connected between the first end of the sensing rod 940 and the fixed plate 930. Specifically, the elastic element 920 can be a spring. Under the action of the elastic element 920, the second end of the sensing rod 940 has a tendency to extend in a direction away from the pressure barrel frame 300.

[0089] The first sensor 900 is located at the lower part of the fixed plate 930. When the first sensor 900 senses the first end of the sensing rod 940, the hanging bucket frame 400 rises.

[0090] In this way, when the trash can is hung on the bin rack 400, the trash can can press the second end of the sensing rod 940 against the bin rack 300, and the elastic element 920 undergoes elastic deformation until the first sensor 900 senses the first end of the sensing rod 940, at which point the first sensor 900 triggers a signal, and the bin rack 400 rises accordingly.

[0091] Continue to refer to Figure 7 , Figure 9 and Figure 10 A limiting rod 960 is provided on the fixing plate 930. Specifically, the limiting rod 960 is screwed to the lower part of the fixing plate 930. The first sensor 900 is located on the side of the limiting rod 960 closer to the bin rack 400, while the limiting rod 960 is located on the side of the sensing rod 940 away from the bin rack 400. Under the action of the elastic member 920, the first end of the sensing rod 940 can abut against the limiting rod 960. In this way, when no garbage bin is hung on the bin rack 400, the limiting rod 960 can limit the sensing rod 940, thereby restricting the range of motion of the sensing rod 940 and preventing the sensing rod 940 from moving excessively under the action of the elastic member 920 after the garbage bin is removed from the bin rack 400, which could cause it to fall or other adverse situations.

[0092] The fixed plate 930 is provided with a rotating shaft 950; the middle part of the sensing rod 940 is rotatably sleeved on the rotating shaft 950, so that the middle part of the sensing rod 940 is hinged to the fixed plate 930 to achieve rotational movement. Of course, the sensing rod 940 can also be set in a linear sliding form on the fixed plate 930, as long as the first end of the sensing rod 940 can trigger the first sensor 900 when the second end of the sensing rod 940 is pressed against the garbage bin holder 300.

[0093] The fixed plate 930 is provided with a first mounting rod 970, the first end of the sensing rod 940 is provided with a second mounting rod 980, and the two ends of the elastic member 920 are respectively mounted on the first mounting rod 970 and the second mounting rod 980, thereby realizing the installation of the elastic member 920.

[0094] The connection method between the fixing plate 930 and the hanging bucket frame 400 is not limited; it can be any method such as screwing, welding, or integral connection. The limiting rod 960 can be connected to the fixing plate 930 by screwing, welding, or integral molding.

[0095] Continue to refer to Figure 7 , Figure 9 and Figure 10 One of the hanging teeth 410 of the hanging rack 400 is provided with a clearance notch 411. The sensing rod 940 passes through the clearance notch 411. The fixing plate 930 is located on the side of the hanging tooth 410 near the pressure rack 300. There are two fixing plates 930 to match the shape of the hanging tooth. This can ensure that the fixing plate 930 and the hanging rack 400 have sufficient connection strength. Moreover, the sensing rod 940, the first sensor 900 and the elastic element 920 can be hidden on one side of the hanging tooth 410, achieving the effect of aesthetics and protection of the first sensor 900.

[0096] The functional principle of the feeding mechanism in this application is illustrated below:

[0097] 1. Standard garbage bin loading

[0098] When the telescopic drive component 800 is in the retracted state, the canvas garbage bin 700 is folded. At this time, the feeding mechanism functions the same as the traditional feeding mechanism. The 120L / 240L standard garbage bins are hung through the hanging bin frame 400, the bins are pressed through the pressing bin frame 300, and the garbage bins are emptied into the garbage container through the lifting arm 100. The 660 / 1100L standard garbage bins are hung through the left support arm 500 and the right support arm 600, and the garbage bins are emptied into the garbage container through the lifting arm 100.

[0099] 2. Loading bulk waste

[0100] When the telescopic drive component 800 is in the extended state, the canvas garbage bin 700 unfolds. At this time, the feeding mechanism can realize the feeding of bulk garbage. Workers can manually pour the bulk garbage into the garbage bin 700 and then perform the feeding action to dump the garbage in the canvas garbage bin 700 into the garbage container.

[0101] 3. Automatic adjustment of hanging bucket height

[0102] The automatic adjustment of the hanging bin height is achieved by the linkage of the first sensor 900 and the second sensor 910. When the standard trash can presses the second end of the sensing rod 940 against the bin-pressing frame 300, the first sensor 900 detects the first end of the sensing rod 940, and the controller issues a rising command, causing the hanging bin frame 400 to rise. When the second sensor 910 detects the hanging bin frame 400, the controller issues a stop command, and the hanging bin frame 400 stops rising. At this time, the position of the hanging bin frame 400 is the optimal hanging bin height.

[0103] In addition, this application also discloses a garbage truck that includes an embodiment of the above-mentioned feeding mechanism, and therefore also has the corresponding structure and beneficial effects.

[0104] In summary, the feeding mechanism and garbage truck of this application have at least the following advantages compared with the prior art:

[0105] 1. The 700 foldable canvas garbage bin can be used to load 120L / 240L / 660L / 1100L standard garbage bins and bulk garbage, saving labor.

[0106] 2. The sensor rod 940 with elastic element 920 reset, the first sensor 900 and the second sensor 910 can realize automatic sensing and raising of the hanging bucket height, reducing the difficulty of hanging the bucket, the failure rate of hanging the bucket and the risk of the bucket falling.
