Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, and in particular to a front protective device for garbage bins. Background Technology

[0002] Compactor garbage trucks integrate four major functions: automatic garbage collection, compression and volume reduction, sealed transportation, and self-unloading. They are one of the core pieces of equipment in the sanitation industry. Internally, hydraulic cylinders push extrusion plates backward to intensely compress loose household waste, significantly reducing its volume and thus increasing the truck's capacity. Wastewater squeezed out of the garbage is diverted to a separate wastewater tank for collection. Figure 9 As shown, an inspection door is provided on the front wall of the garbage compartment to facilitate maintenance of the hydraulic cylinders or cleaning of the space in front of the squeezing plate.

[0003] In actual operation, the moisture content of different types of waste varies greatly, and the wastewater squeezed out by the extrusion plate may not flow into the wastewater tank in time. Therefore, if... Figure 6 As shown, a considerable amount of sewage often exists at the bottom of the garbage container. During the push-back phase, the squeezing plate pushes the sewage in the opposite direction towards the front wall of the garbage container, as... Figure 7 As shown, at the end of the return journey, a higher water level is formed at the front wall of the compartment, and as... Figure 8 The surge impact can cause sewage to overflow from the inspection door on the front wall of the garbage truck. The front of the garbage truck houses important components such as the engine and transmission system, and the sewage may contain heavy metals or acidic components that could corrode these parts. To address this, the inventors attempted to improve the sealing of the inspection door. However, because the door opens outwards, its sealing relies solely on a sealing structure pressed against the outer surface of the front wall. The surge impact can still create gaps between the door and the front wall, failing to fundamentally solve the sewage overflow problem. Troubled by this issue, further protective improvements are needed to the front of the existing compressed garbage truck's garbage compartment, leading to this invention. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a protective device in front of a garbage compartment that significantly reduces the impact of sewage impact, helps to reduce sewage overflow and does not affect maintenance personnel entering and exiting.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a front protection device for a garbage container, including a protective baffle installed at the lower part of the inspection port on the front wall of the garbage container. The protective baffle is located inside the inspection port. The protective baffle has side abutments extending beyond the side edges of the inspection port on both sides. The lower end of the protective baffle has a lower abutment extending downward beyond the lower edge of the inspection port. The side abutments and the lower abutments are attached to the front wall of the container. A rotatable connection structure is provided between the lower abutment and the front wall of the container. A fixed connection structure is provided between the upper parts of the two side abutments and the front wall of the container.

[0006] As a preferred technical solution, the fixed connection structure includes a pin-shaped spring fixedly installed on the front wall of the compartment; the pin-shaped spring includes a sheet connecting part fixedly connected to the front wall of the compartment, and at least two spring sheets evenly distributed circumferentially are integrally provided on the sheet connecting part, the spring sheets facing the side abutment and forming a pin shape; each spring sheet has a correspondingly bent pressing section that protrudes outward in the radial direction, the side abutment is provided with a fixed connection hole that engages with the pin-shaped spring, the pressing section is located on the side of the fixed connection hole away from the front wall of the compartment, and the pressing section is used to press the side abutment against the front wall of the compartment.

[0007] As a preferred technical solution, a spring connecting screw hole is provided on the front wall of the compartment, and a spring fixing bolt with its head pressed against the plate connecting part is installed on the spring connecting screw hole. The plate connecting part is provided with a spring connecting through hole corresponding to the spring fixing bolt.

[0008] As a preferred technical solution, the rotating connection structure includes a rotating connection seat fixedly installed on the front wall of the compartment and located below the inspection port. The rotating connection seat is provided with a groove that is inclined towards the inspection port to form a rotating connection groove. A rotating connection pin located in the rotating connection groove is fixedly provided on the lower abutment.

[0009] As a preferred technical solution, a splash-proof baffle is fixedly provided above the outer surface of the protective baffle, and a flexible splash-proof structure is fixedly provided around the periphery of the splash-proof baffle.

[0010] As a preferred technical solution, the splash guard is positioned obliquely to the upper outer side.

[0011] As a preferred technical solution, the inner wall of the protective baffle is provided with a reinforcing structure.

[0012] As a preferred technical solution, an inspection door located outside the inspection port is installed on the front wall of the compartment.

[0013] Due to the adoption of the above technical solution, the front protection device of the garbage container includes a protective baffle installed at the lower part of the inspection port on the front wall of the garbage container. The protective baffle is located inside the inspection port. Side abutments extending beyond the side edges of the inspection port are provided on both sides of the protective baffle. A lower abutment extending downward beyond the lower edge of the inspection port is provided at the lower end of the protective baffle. The side abutments and the lower abutments are abutted against the front wall of the container. A rotatable connection structure is provided between the lower abutment and the front wall of the container, and a fixed connection structure is provided between the upper parts of the two side abutments and the front wall of the container. This utility model, by adding the protective baffle at the lower part of the inspection port, blocks the surge impact of sewage, preventing the surge from directly impacting the inspection door, thus reducing sewage overflow from the inspection door and preventing corrosion of the front components of the garbage container. Since the protective baffle is fixed at the top and rotatable at the bottom, when maintenance is required, it can be moved away from the maintenance port by disconnecting the fixed connection at the top, restoring the maintenance port to its normal size, so as not to affect the maintenance access.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0026] like Figures 1 to 5 As shown, the front protective device of the garbage compartment includes a protective baffle 2 installed at the lower part of the inspection port 12 on the front wall 11 of the garbage compartment 1. Conventionally, an inspection door 13 located outside the inspection port 12 is installed on the front wall 11 of the compartment. The inspection door 13 is a swing door and is closed when it is against the outer wall of the front wall 11. The inspection door 13 is a well-known and commonly used technology, and will not be described in detail here. In this embodiment, "inner" and "outer" refer to the inside and outside of the garbage compartment 1, and "front" and "rear" refer to the front and rear positions during the movement of the garbage truck. The purpose is to explain the structural principle more clearly, not to limit the scope of protection.

[0027] The protective baffle 2 is located inside the inspection port 12. The protective baffle 2 has side abutment portions 21 extending beyond the side edges of the inspection port 12 on both sides, and a lower abutment portion 22 extending downward beyond the lower edge of the inspection port 12 at its lower end. The side abutment portions 21 and the lower abutment portion 22 are abutted against the front wall 11 of the compartment. With the abutment of the side abutment portions 21 and the lower abutment portion 22, the protective baffle 2 provides good impact resistance, thereby protecting the inspection door 13 from surge impacts.

[0028] Preferably, the inner wall of the protective baffle 2 is provided with a reinforcing structure 23 to further improve the impact resistance of the protective baffle 2. In this embodiment, the reinforcing structure 23 is a plurality of reinforcing vertical ribs provided on the inner wall of the protective baffle 2, and the reinforcing vertical ribs extend to the lower abutment portion 22.

[0029] A rotatable connection structure 4 is provided between the lower abutment part 22 and the front wall 11 of the compartment, and a fixed connection structure 3 is provided between the upper part of the two side abutment parts 21 and the front wall 11 of the compartment. Through this vertical connection, the upper side abutment part 21 and the lower abutment part 22 are made to fit against the front wall 11 of the compartment. This fit creates a good sealing effect, so even if sewage is impacted, it is not easy for it to rush from the protective position of the protective baffle 2 into the inspection port 12.

[0030] like Figure 5 As shown, the fixed connection structure 3 in this embodiment includes a pin spring 31 fixedly installed on the front wall 11 of the compartment; the pin spring 31 includes a sheet connecting part 32 fixedly connected to the front wall 11 of the compartment, and at least two spring sheets 33 are integrally provided on the sheet connecting part 32, which are evenly distributed in the circumferential direction. The spring sheets 33 face the side abutment part 21 and are arranged in a pin shape; each spring sheet 33 has a corresponding bending of a pressing section 34 that protrudes outward in the radial direction. The side abutment part 21 is provided with a fixed connection hole 35 that is sleeved with the pin spring 31. The pressing section 34 is located on the side of the fixed connection hole 35 away from the front wall 11 of the compartment, and the pressing section 34 is used to press the side abutment part 21 against the front wall 11 of the compartment.

[0031] The above structure achieves the purpose of fixing the upper part of the protective baffle 2 to the front wall 11 of the garbage compartment. When releasing the fixed connection, a force needs to be applied to the upper part of the protective baffle 2 towards the inside of the garbage compartment 1, so that the fixed connection hole 35 presses against the squeezing section 34, forcing each of the spring plates 33 to gather and deform. When the outer diameter of the squeezing section 34 is no greater than the diameter of the fixed connection hole 35, the fixed connection hole 35 can move towards the inside of the garbage compartment 1, the protective baffle 2 flips and moves away from the position of the inspection port 12, and the inspection port 12 returns to its normal size, without affecting the access for maintenance. After maintenance, by flipping the protective baffle 2 back, the fixed connection hole 35 presses the extrusion section 34 again, causing it to gather and deform. The upper side of the protective baffle 2 can then rest against the front wall 11 of the compartment. At this time, the extrusion section 34 recovers its deformation due to elastic force and is held at the end of the fixed connection hole 35 away from the front wall 11, forming a fixed connection to the upper part of the protective baffle 2.

[0032] Based on the above principles, in the free state, the outer diameter of the compression section 34 should be larger than the diameter of the fixed connection hole 35, and the outer diameter of the portion of each spring sheet 33 outside the compression section 34 should be smaller than the diameter of the fixed connection hole 35. Furthermore, the sides of the compression section 34, whether near or away from the front wall 11, should have a gradually changing outer diameter to facilitate the force generated by the fixed connection hole 35 during assembly and disassembly. Ideally, the ends of the fixed connection hole 35 near or away from the front wall 11 should also be chamfered to further facilitate the smooth compression of the compression section 34 during assembly and disassembly.

[0033] Furthermore, a spring connecting screw hole 36 is provided on the front wall 11 of the compartment, and a spring fixing bolt 37 with its head pressing against the plate connecting part 32 is installed on the spring connecting screw hole 36. The plate connecting part 32 is provided with a spring connecting through hole corresponding to the spring fixing bolt 37. Thus, by machining the spring connecting screw hole 36 on the front wall 11 of the compartment, the pin spring 31 can be installed.

[0034] like Figure 2 As shown, the rotating connection structure 4 in this embodiment includes a rotating connection seat 41 fixedly installed on the front wall 11 of the compartment and located below the inspection port 12. The rotating connection seat 41 has a groove that is angled towards the inspection port 12 to form a rotating connection groove 42. A rotating connection pin 43 is fixedly installed on the lower abutment 22 and located in the rotating connection groove 42. Thus, after the fixed connection structure 3 is released, the rotating connection pin 43 can be removed from the rotating connection groove 42 by lifting the protective baffle 2, thereby achieving the purpose of completely removing the protective baffle 2. This can further reduce the obstruction of the protective baffle 2 when entering and exiting for maintenance.

[0035] Accordingly, the protective baffle 2 and its upper abutment, connecting pin, and other structures can be integrally manufactured using plastic materials, resulting in a lightweight overall structure and reduced force during assembly and disassembly. Furthermore, the open slot of the rotating connecting groove 42 facilitates the fixing of the upper fixed connecting hole 35 to the pin-shaped spring 31 during reinstallation of the protective baffle 2, further reducing installation force. More specifically, when installing the protective baffle 2, first, the rotating connecting pin 43 is engaged in the rotating connecting groove 42. Then, the protective baffle 2 is rotated towards the front wall 11 of the compartment using the rotating connecting pin 43, so that the fixed connecting hole 35 is fitted onto the pin spring 31. When the fixed connecting hole 35 is close to the pin spring 31, there may be a small height difference between the fixed connecting hole 35 and the pin spring 31. In order to align the fixed connecting hole 35 and the pin spring 31 and achieve a smooth connection, the protective baffle 2 can be slightly lifted upwards. At this time, it is equivalent to using the upper opening of the rotating connecting groove 42 to make the rotating connecting pin 43 form a small upward displacement, thereby achieving the purpose of smoothly fitting the fixed connecting hole 35 and the pin spring 31. After the sleeve installation, the rotating connecting pin 43 sinks back into the rotating connecting groove 42. The rotating connecting groove 42 forms a restriction at the lower part of the rotating connecting pin 43 and on the side away from the front wall 11, thus cooperating with the fixing connection structure 3 to achieve the purpose of fixing the protective baffle 2. The rotating connecting seat 41 is also fixed to the front wall 11 with bolts after drilling screw holes in the front wall 11.

[0036] Preferably, such as Figure 2 and Figure 4 As shown, a splash guard 5 is fixedly provided above the outer surface of the protective baffle 2, and a flexible splash guard structure 51 is fixedly provided around the periphery of the splash guard 5. The height of the protective baffle 2 is set according to the possible height of the surge impact. In this embodiment, the splash guard 5 is added to it to reduce the amount of splashed water entering the inspection port 12 from the top. The flexible splash guard structure 51 on the splash guard 5 ensures that the gap between the splash guard 5 and the inspection port 12 and the inspection door 13 also has a blocking effect on splashed water, and its flexibility does not affect the disassembly and assembly of the protective baffle 2 or the opening and closing of the inspection door 13. The flexible splash guard structure 51 can be implemented with a brush structure. Preferably, the splash guard 5 is set obliquely to the upper and outer side so that the blocked water can flow back into the garbage bin 1 along the splash guard 5.

[0037] In this embodiment, a protective baffle 2 is added to the lower part of the inspection port 12. Through the interlocking of the side abutment 21 and the lower abutment 22, and the reinforcement of the reinforcing structure 23, it reliably blocks surge impacts, effectively preventing surges from directly impacting the inspection door 13. This reduces sewage overflow from the inspection door 13 and helps prevent corrosion of the front components of the garbage container 1. In this embodiment, the upper part of the protective baffle 2 is fixedly connected to the pin spring 31 via a fixed connection hole 35, while the lower part is restricted by a rotating connection slot 42 and a rotating connection pin 43. This ensures a reliable fixed connection of the protective baffle 2 and facilitates overall disassembly. When maintenance is required, the inspection port 12 can be easily restored to its normal size without affecting access for maintenance. In this embodiment, the protective baffle 2 can be installed by machining designated screw holes on the front wall 11 of the container, without affecting the existing structure such as the inspection door 13, making it convenient for direct modification and use on existing garbage containers 1.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
