Description

Technical Field

[0001] This invention relates to the field of waste utilization technology, specifically to a garbage bag breaking and lifting mechanism, a garbage bin station, and a bag breaking, lifting, and unloading method. Background Technology

[0002] Wet waste accounts for about 60% to 70% of the total amount of waste generated per capita. Its main components are kitchen waste and food waste. It is characterized by high organic matter content, high water content, and easy decomposition. If wet waste in garbage cans cannot be reduced on-site, it will bring a heavy burden and safety hazards to garbage transportation and the environment.

[0003] The first step in reducing the volume of wet waste in the garbage bin section is to break the garbage bags. After the bags are broken, they usually enter the volume reduction device along with the wet waste. There are two main methods for breaking garbage bags: one is to use the bag-breaking process as it falls into the bin, such as the bag-breaking knives in CN218752746U and CN215796067U; the other is to break the garbage bag after it has fallen into place, such as the method disclosed in CN115092488A, where the supporting surface of the garbage bag consists of two flaps, and the teeth or knives used for breaking the bag protrude from the supporting surface of the garbage bag and are respectively set on the two flaps. The flaps flip back and forth, increasing the spacing between the teeth and tearing the garbage bag. The drawback of the above methods is that after the garbage inside the bag is unloaded through the opening, the garbage bag and the garbage inside the bag are introduced into the volume reduction device together, which cannot achieve the separate treatment of plastic garbage bags and wet waste. Summary of the Invention

[0004] One of the objectives of this invention is to overcome the deficiencies in the prior art and provide a garbage bag breaking and lifting mechanism. By utilizing the extension and retraction of the telescopic component and its movement in the extension and retraction direction, the garbage bag is sequentially punctured, grabbed, and lifted. The driving mechanism is simple and reliable.

[0005] To achieve the above-mentioned technical effects, the technical solution of the present invention is: a garbage bag breaking and lifting mechanism, comprising:

[0006] The telescopic component has a piercing element and a claw seat fixed at its two ends that are opposite to each other in the telescopic direction;

[0007] The garbage bag carrier is located below the telescopic member and has a discharge hole through which the piercing member passes;

[0008] The bag-grabbing claws are distributed on the side of the telescopic member and are hinged to the claw base;

[0009] The connecting rod seat is movably connected to the telescopic member and slides along the telescopic direction;

[0010] The connecting rod is hinged at both ends to the bag gripper and the connecting rod seat, respectively.

[0011] A drive mechanism is configured to move and extend the telescopic member along the telescopic direction; so that the piercing member pierces the garbage bag, the telescopic member shortens while the bag-grabbing claws open; or the telescopic member extends while the bag-grabbing claws close.

[0012] A preferred technical solution is that the piercing member or telescopic member is provided with a blocking part, which is located below the connecting rod seat.

[0013] The preferred technical solution is that the telescopic component is a self-weight telescopic component.

[0014] A preferred technical solution is that the driving mechanism includes a vibration mechanism, which drives the telescopic member to vibrate along at least the telescopic direction.

[0015] A preferred technical solution is that the driving mechanism is a linear drive component, and the linear drive component is connected to the end of the telescopic component away from the garbage bag carrier.

[0016] A preferred technical solution is that the driving mechanism is a linear cylinder;

[0017] The inner cavity of the linear cylinder is divided into a rod chamber and a rodless chamber by a piston rod sealing ring. A compression spring is provided in the rodless chamber, and the compression spring has compression deformation in the extension direction of the piston rod. An air valve is connected to the rod chamber, and the air valve is configured to control the filling and cutting off of air into the rod chamber so that the compression spring excites the piston rod.

[0018] A preferred technical solution further includes an elastic squeezing member. The piercing member includes at least two blades, and the blades are distributed and arranged to include the elastic squeezing member. Along the extension direction, the elastic squeezing member is correspondingly arranged in the angle between adjacent blades and the bag-grabbing claw. The elastic squeezing member is configured to squeeze the garbage bag grasped by the bag-grabbing claw.

[0019] The second objective of this invention is to provide a garbage bin station, including a dry garbage bin and a wet garbage bin, including the aforementioned garbage bag breaking and lifting mechanism, and also including a bag transfer mechanism. The bag transfer mechanism is connected to the garbage bag breaking and lifting mechanism and is configured to transfer the garbage bag after garbage is released to the dry garbage bin.

[0020] A preferred technical solution is that the bag transfer mechanism includes a removable pusher disposed above the dry waste bin, the pusher having a top surface that pushes against the piercing member in a vertical direction.

[0021] The third objective of this invention is to provide a method for breaking open and lifting garbage bags for unloading, based on the aforementioned garbage bag breaking and lifting mechanism, comprising the following steps:

[0022] S1: The driving mechanism drives the telescopic member to move towards the garbage bag covering the feeding hole and reduces the length of the telescopic member in the telescopic direction. The distance between the piercing member and the claw seat decreases, and the bag-grabbing claw opens until the piercing member penetrates the feeding hole and pierces the bottom of the garbage bag to form a hole.

[0023] S3: The driving mechanism drives the telescopic member to move away from the garbage bag and increases the length of the telescopic member in the telescopic direction. The distance between the piercing member and the claw seat increases, the bag-grabbing claw retracts and grabs the garbage bag, and the garbage is released from the garbage bag through the tear.

[0024] The advantages and beneficial effects of this invention are as follows:

[0025] The telescopic component of this garbage bag breaking and lifting mechanism is fixedly equipped with a piercing component and a claw seat at both ends. When piercing the garbage bag, the resistance of the garbage bag to the piercing component is used to open the gripping claw through the linkage mechanism. When lifting the garbage bag, the force of the garbage inside the bag on the piercing component, as well as the weight of the telescopic component, the linkage seat, and the piercing component, are used to make the gripping claw close, thereby realizing the actions of piercing the garbage bag, grabbing the garbage bag, and lifting the garbage bag in sequence.

[0026] The bag breaking, grabbing, and lifting functions are all based on the same drive mechanism. The number of drive components is small, which helps to reduce the failure rate of the drive mechanism, reduce the maintenance costs of the equipment and the garbage bin station, and is suitable for retrofitting existing garbage bin stations.

[0027] The bag-breaking and unloading method is simple and quick, ensuring the normal feeding of subsequent wet waste bags. Attached Figure Description

[0035] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0036] In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating orientation or positional relationship are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example

[0038] like Figure 1-2 As shown, the garbage bag breaking and lifting mechanism of this embodiment includes a telescopic member 1, a garbage bag carrier 2, a bag gripper 3, a connecting rod 4, a connecting rod seat 8, and a driving mechanism 5. The telescopic member 1 has a piercing member 6 and a gripper seat 7 fixed at opposite ends in the telescopic direction. The garbage bag carrier 2 is located below the telescopic member 1 and has a discharge hole 201 for the piercing member 6 to pass through. The bag grippers 3 are distributed on the sides of the telescopic member 1 and are hinged to the gripper seat 7. The connecting rod seat 8 is movably connected to the telescopic member 1 and slides along the telescopic direction. The two ends of the connecting rod 4 are hinged to the bag gripper 3 and the connecting rod seat 8, respectively. The driving mechanism 5 is configured to move and extend / retract the telescopic member 1 along the telescopic direction, so that the piercing member 6 pierces the garbage bag, and the bag gripper 3 opens while the telescopic member 1 shortens; or the bag gripper 3 closes while the telescopic member 1 extends.

[0039] The telescopic component 1 can be either a self-weight telescopic component 1 or an automatic telescopic component 1, such as a pneumatic telescopic rod, a hydraulic telescopic rod, or a self-weight telescopic rod. The distance between the two ends in opposite directions of telescopic movement has a maximum value and a minimum value. It can be understood that as the aforementioned distance between the two ends gradually increases, the claw seat 7 and the connecting rod seat 8 gradually move away from each other, and due to the action of the connecting rod, the claw opening of the bag gripper 3 gradually closes; conversely, the claw opening of the bag gripper 3 gradually opens.

[0040] Optionally, in addition to being movably connected to the telescopic member 1 and sliding along the telescopic direction, the connecting rod seat 8 can also slide along the telescopic direction of the piercing member 6. For example, a guide rail is provided on the outside of the telescopic member 1, and the slider of the connecting rod seat 8 moves along the guide rail; or as... Figure 1-2 As shown, the connecting rod seat 8 is sleeved on the outer periphery of the telescopic member 1. Furthermore, the sleeve hole of the connecting rod seat 8 can also be sleeved on the outer periphery of the piercing member 6.

[0041] By comprehensively considering the lengths of the gripper 3, connecting rod 4, and telescopic rod, especially the changes in the length of the telescopic rod, it is ensured that the connecting rod seat 8 does not detach from the telescopic rod and the piercing component 6.

[0042] In this embodiment, the bag-gripping claw 3 has a hinged end and a free end. The hinged end is hinged to the claw base 7, and the free end has a bent hook portion 301 on the side facing the telescopic member 1 to form a claw shape for gripping garbage bags. The hinge of the connecting rod 4 is located between the hinged end and the free end. The number of bag-gripping claws 3 can be two or more. Two bag-gripping claws 3 are arranged on opposite sides of the telescopic rod; three or more bag-gripping claws 3 surround the periphery of the telescopic rod. It is understood that the bag-gripping claws 3 are preferably evenly distributed in the circumferential direction of the telescopic rod to ensure that the force on the bag-gripping claws 3 is uniform.

[0043] In this embodiment, the piercing member 6 has a piercing tip 601 and a fixed end that enlarges the opening. The fixed end is fixedly connected to the telescopic member 1 so that it can pierce the top and bottom surfaces of the garbage bag to form an opening large enough to accommodate the garbage passing through and falling.

[0044] like Figure 1-2 As shown, the piercing element 6 is fixedly equipped with two or more blades, which are distributed around the periphery of the telescopic element 1. Compared with a rod-shaped blade with a sharp end, the combination of blades has a smaller self-weight, making it easier to pierce the garbage bag and form a larger opening. The larger the opening, the faster the garbage falls, and the shorter the piercing and falling time of a single garbage bag, which helps to improve the bag-breaking efficiency. Figure 1-2 The puncture component 6 includes three blades, which are distributed at equal angles around the central axis of the telescopic component 1.

[0045] Furthermore, the distance between the blade tip and the center of the blade distribution gradually increases along the direction from the piercing member 6 to the claw seat 7. The sharp piercing tip of the blades can quickly pierce the garbage bag. When the wet garbage contains hard objects such as bones, the sharp piercing tip can push the hard objects away from the predetermined piercing path, reducing the probability that the hard objects will block the bottom of the garbage bag and fail to pierce it successfully.

[0046] The function of the garbage bag carrier 2 is to support the garbage bags. To ensure that the garbage bags completely cover the discharge port after being placed, the top surface of the carrier can be a guide surface, including but not limited to a frustum-shaped guide surface, with the discharge port located at the bottom end of the frustum-shaped guide surface. This bag-breaking and lifting mechanism is not suitable for garbage bags that are too small, such as garbage bags that can fall directly through the discharge port.

[0047] The function of the drive mechanism 5 is to drive the telescopic component 1 to move and extend. These two actions can be achieved using two independent drive components. For example, when piercing a garbage bag, one drive component first extends the telescopic component 1, and then the other drive component moves both the telescopic component 1 and the piercing component 6 until the piercing component 6 passes through the discharge hole 201. When driving the telescopic component 1 and the piercing component 6, it is essential to ensure that the gripping claw 3 opens to a predetermined angle; otherwise, the unclamped gripping claw 3 will abut against the garbage bag, preventing it from opening further. The drive mechanism 5 is specifically selected based on the structure of the telescopic component 1.

[0048] like Figure 1-2 As shown, the drive mechanism 5 is connected to the end of the telescopic member 1 away from the piercing member 6. Alternatively, in some embodiments, the drive mechanism 5 is located on the side of the claw seat 7 away from the telescopic direction of the gripping claw 3. When the telescopic direction of the telescopic member 1 is set vertically and the drive mechanism 5 is located on the horizontal side of the telescopic member 1, there is a possibility that the drive mechanism 5 will interfere with the garbage bag containing space and be contaminated by garbage.

[0049] In this embodiment, the telescopic member 1 is a self-weight telescopic member 1. Figure 1 The telescopic sleeve 1 is used in the middle. When the piercing element 6 comes into contact with the garbage bag, the garbage bag exerts a contracting thrust on the telescopic element 1, causing the length of the telescopic sleeve 1 to shorten. Compared with automatic telescopic elements, the use of a telescopic sleeve 1 further simplifies the overall drive control of the garbage bag. The drive mechanism 5 is a single linear drive element. The drive mechanism 5 drives the telescopic element 1 and the piercing element 6 to move towards the garbage bag. During the piercing process, due to the piercing strength of the garbage bag itself and the resistance of the garbage inside the bag to the piercing element 6, the gripping claw 3 is forced to open. The stroke of the linear drive element can be set to drive the telescopic sleeve 1 to its shortest state and the piercing element 6 to a predetermined relative position in the discharge hole 201.

[0050] Figure 1The telescopic sleeve consists of three nested sections. The section with the largest diameter is fixedly connected to the piercing element 6, and the section with the smallest diameter is fixedly connected to the claw seat 7. Compared to a two-section sleeve with the same longest length, the three-section sleeve has a larger difference between its maximum and minimum lengths. During the transition from the maximum to the minimum length of the telescopic element 1, the rotation angle of the connecting rod 4 tends to increase (within a range greater than 90° and less than 180°). At its minimum length, the connecting rod 4 is more fully folded under the bag-grabbing claw 3, forming a centrally arched garbage bag accommodating space. Based on the fixed length of the bag-grabbing claw 3, the open bag-grabbing claw 3 has a larger outer diameter to accommodate garbage bags of different sizes.

[0051] Furthermore, the discharge port 201 is connected to the waste reduction mechanism of the waste bin station.

[0052] like Figure 1-2 As shown, in another preferred embodiment, the telescopic member 1 is provided with a blocking part, which is located below the connecting rod seat 8. Figure 1-2 In this configuration, the piercing member 6 itself serves as a blocking element. Alternatively, the blocking element can also be located on the piercing member 6, for example, at its tip. The blocking element 101 in the figure is used to prevent the connecting rod seat 8 from descending further, ensuring that the connecting rod seat 8 is always fitted onto the telescopic member or the piercing member.

[0053] In some embodiments, the drive mechanism 5 includes a vibration mechanism that drives the telescopic member 1 to vibrate along at least the telescopic direction.

[0054] The vibration direction of the vibration mechanism driving the telescopic member 1 can be selected as vibrating only along the telescopic direction, or vibrating in any direction in the plane perpendicular to the telescopic direction, or in any direction having components in the telescopic direction and the vertical plane. The preferred vibration direction includes the telescopic direction.

[0055] When the drive mechanism 5 drives the telescopic component 1 to move along the telescopic direction from the piercing component 6 to the claw seat 7, the garbage bag is in the lifted state. At this time, an excitation force is applied to the telescopic component 1, and the garbage bag is also excited at the same time, which accelerates the wet garbage from falling from the garbage belt and further shortens the processing time for releasing garbage from a single garbage bag.

[0056] The vibration mechanism can be selected to apply excitation force to the telescopic member 1, such as a drive mechanism 5 including a vibration motor.

[0057] like Figure 1-2 As shown, in another preferred embodiment, the drive mechanism 5 is a linear drive member, which is connected to the end of the telescopic member 1 away from the garbage bag carrier 2.

[0058] like Figure 3 As shown, in another preferred embodiment, the drive mechanism 5 is a linear cylinder;

[0059] The inner cavity of the linear cylinder is divided into a rod chamber and a rodless chamber by a sealing ring of the piston rod 501. A compression spring 502 is provided in the rodless chamber, and the compression spring 502 has compression deformation in the extension direction of the piston rod 501. A gas valve 503 is connected to the rod chamber. The gas valve 503 is configured to control the filling and cutting off of gas to the rod chamber so that the compression spring 502 excites the piston rod 501.

[0060] In the non-vibration state, the compression spring 502 acts as a buffer for the piston rod 501. When the air valve 503 controls the rapid inflation and de-inflation of the rod chamber, the compression spring 502 is compressed after inflation and recovers its deformation when the air is de-inflated. The compression spring 502 applies an excitation force to the piston rod 501, which further transmits the excitation force to the gripper claw 3 and the garbage bag. The linear cylinder with the above structure, combined with the functions of the drive mechanism 5 and the vibration mechanism, can sequentially realize the puncturing, gripping, lifting, and vibration of the garbage bag, making the drive mechanism 5 simpler.

[0061] like Figure 4 As shown, in some embodiments, an elastic squeezing member 11 is also included. The piercing member 6 includes at least two blades, and the blades are distributed to include the elastic squeezing member 11. The elastic squeezing member 11 is correspondingly disposed in the included angle between adjacent blades and the bag-grabbing claw 3 along the extension direction. The elastic squeezing member 11 is configured to squeeze the garbage bag grasped by the bag-grabbing claw 3. Specifically, the elastic squeezing member 11 is fixed at a certain height. When the piercing member 6 and the bag-grabbing claw 3 descend to pierce the garbage bag, they pass through the gap between adjacent elastic squeezing members 11. During the upward movement after grasping the garbage bag, the elastic squeezing member 11 presses against the surface of the garbage bag located in the included angle area of ​​adjacent bag-grabbing claws 3, promoting the full unloading of fluid substances in the wet garbage bag.

[0062] The outer edge of the elastic extrusion member 11 may be fixed to the bracket.

[0063] The embodiment of the garbage bin station includes a dry garbage bin 9 and a wet garbage bin, including the aforementioned garbage bag breaking and lifting mechanism, and also includes a bag transfer mechanism. The bag transfer mechanism is connected to the garbage bag breaking and lifting mechanism and is configured to transfer the garbage bag after garbage is released to the dry garbage bin 9.

[0064] In this embodiment, the bag transfer mechanism is connected to the drive mechanism 5. For example, the bag transfer mechanism includes a guide rail 12 and a lateral movement mechanism. The guide rail 12 is positioned above the wet waste inlet and the dry waste bin inlet. The drive mechanism 5 slides with the guide rail 12 via a slider. The lateral movement mechanism drives the slider and guide rail 12 to move laterally above the dry waste bin inlet. The lateral movement direction is as follows: Figure 5-6 As indicated by the double arrows, transfer the garbage bag after releasing the garbage to the dry waste bin 9.

[0065] like Figure 5-6 As shown, the bag transfer mechanism includes a removable pusher 10 disposed above the dry waste bin 9, the pusher 10 having a top surface that pushes against the piercing member 6 in the vertical direction.

[0066] The pusher 10 folds up from bottom to top to a predetermined position where it pushes against the piercing member 6. As the pusher 10 pushes against the piercing member 6, the bag gripper 3 opens, and the garbage bag is released and hung on the pusher 10. The pusher 10 then folds down from top to bottom to reset, and the garbage bag is fed into the dry waste bin 9.

[0067] Furthermore, it is understandable that, in order to achieve on-site reduction of wet waste, the waste collection station also includes a waste reduction mechanism. This mechanism includes a solid-liquid separation unit, pipes or storage tanks for collecting, discharging, or storing liquid separation products, and waste bins for collecting and storing solid separation products. Even further, a crushing mechanism is connected to the feed side of the solid-liquid separation unit.

[0068] The bag-breaking, lifting, and unloading method based on the above-mentioned garbage bag breaking and lifting mechanism includes the following steps:

[0069] S1: The drive mechanism 5 drives the telescopic member 1 to move towards the garbage bag covering the feeding hole 201 and reduces the length of the telescopic member 1 in the telescopic direction. The distance between the piercing member 6 and the claw seat 7 decreases, and the bag gripping claw 3 opens until the piercing member 6 penetrates the feeding hole 201 and pierces the bottom of the garbage bag to form a hole.

[0070] S3: The drive mechanism 5 drives the telescopic component 1 to move away from the garbage bag and increases the length of the telescopic component 1 in the telescopic direction. The distance between the piercing component 6 and the claw seat 7 increases, the bag grabbing claw 3 closes and grabs the garbage bag, and the garbage is released from the garbage bag through the opening.

[0071] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
