Description

Technical Field

[0001] This utility model belongs to the technical field of rear-loading compression garbage trucks, specifically relating to a filler that improves the stability of scraping material and a rear-loading compression garbage truck. Background Technology

[0002] Rear-loading compactor garbage trucks are high-efficiency sanitation vehicles specifically designed for the collection, compression, and transportation of urban household waste. They are widely used in urban streets, communities, factories, and other locations for waste collection and transfer. Their core function is to significantly reduce the volume of loose waste through a compression device, thereby improving single-trip transportation efficiency and reducing collection costs. The core component is the filler, which mainly consists of a loading hopper, scraper mechanism, pusher mechanism, protective cover, guide channels and reinforcing ribs, hydraulic system interface, drainage device, and safety devices. Its core design focuses on efficiently receiving and compressing waste while ensuring operational stability, sealing, and safety. The compression component of the filler is the scraper and sliding plate system. The scraper is hydraulically driven to reciprocate on the sliding plate track, compressing the waste.

[0003] As disclosed in Chinese Patent CN112499062A, a rear-compressor garbage truck, the compaction device includes a sliding plate and a scraper; the garbage filling box is provided with a sliding groove; the sliding plate is connected through the sliding groove; a rotating shaft is provided on the sliding plate; the scraper is connected to the sliding plate through the rotating shaft. Garbage is dumped into the garbage filling box by the unloading device, and the garbage is compacted and filled into the box by the retraction of the sliding plate and scraper. After filling, the garbage is pushed out of the box by a pusher plate.

[0004] However, when using a rear-loading compactor garbage truck for loading garbage, the uneven distribution of garbage in the hopper results in uneven force on the scraper mechanism as it scrapes the garbage in; the garbage in the hopper also contains harder solid waste. During the process of the scraper being driven by the sliding plate, the scraper exerts a reaction force on the sliding plate, affecting it and causing it to sway from side to side. This not only increases noise but also affects the stability of the sliding plate's movement. This not only prevents the scraper from moving smoothly along the predetermined track, affecting compression efficiency, but also the sliding plate swaying may damage the seal between the loader and the truck body, leading to garbage or sewage leakage and secondary pollution. The sliding plate swaying also intensifies friction with the track, causing abnormal wear on the sliding plate, track, and guide components, shortening their service life. Long-term swaying may lead to fatigue fracture of the sliding plate, scraper, or key components of the loader (such as hinge points and welds), causing equipment failure. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention aims to solve the problem that the scraper of a traditional rear-loading compactor garbage truck is prone to uneven forces during the scraping process, causing the scraper and slide plate to sway left and right, increasing noise, affecting the stability of the slide plate movement, and making the compression operation unstable. Prolonged swaying can easily lead to damage to the slide plate, scraper, or key components of the loader. This invention provides a filler and a rear-loading compactor garbage truck that improves scraping stability. Guide groove supports are welded to the baffle plate of the loader, forming several guide grooves. Additionally, a corresponding number of reinforcing ribs are welded to the back of the slide plate, allowing the reinforcing ribs on the slide plate mechanism to slide within the guide grooves, thereby limiting the left and right swaying of the slide plate mechanism, making the scraping process more stable and reliable, and reducing component damage.

[0006] To achieve the above objectives, this utility model provides a filler for improving scraping stability, comprising a housing, a baffle plate, a scraper, a hopper, and a sliding plate.

[0007] The baffle is fixed above the filler. The sliding plate moves back and forth relative to the baffle. When the sliding plate moves, it drives the scraper to move. The scraper is driven to rotate by the hydraulic cylinder. When the sliding plate drives the scraper to move obliquely upward, it compresses the garbage in the hopper and pushes it into the truck.

[0008] The lower end of the baffle plate is provided with multiple evenly arranged guide grooves, and limit blocks are provided on both sides of the guide groove notches. The space between the limit blocks and the guide grooves form a guide channel.

[0009] The lower surface of the slide plate is provided with multiple evenly arranged guide strips. The guide strips are arranged longitudinally, and each guide strip corresponds to a guide channel. The guide strips are embedded in the guide channel formed by the guide groove and the limiting block with a clearance fit.

[0010] According to another embodiment of the present invention or any of the foregoing embodiments, the guide groove is rectangular, U-shaped or C-shaped.

[0011] According to another embodiment of the present invention or any of the foregoing embodiments, the lower end of the baffle plate is connected to a guide bracket, the guide bracket is the same width as the baffle plate, and the limiting block is mechanically connected or welded to the guide bracket.

[0012] According to another embodiment of the present invention or any of the foregoing embodiments, the limiting block is a semi-enclosed block with a parallelogram cross-section formed by bending a stainless steel strip.

[0013] According to another embodiment of the present invention or any of the foregoing embodiments, the filler plate has two or more reinforcing ribs on its upper surface, and the reinforcing ribs are respectively connected to the limiting block.

[0014] According to another embodiment of the present invention or any of the foregoing embodiments, the guide bar and the lower surface of the slide plate are of equal length in the direction of movement.

[0015] According to another embodiment of the present invention or any of the foregoing embodiments, the guide bar is elongated and welded to the lower surface of the slide plate.

[0016] Accordingly, a rear-loading compression garbage truck with improved material scraping stability is disclosed, including the aforementioned filler.

[0017] The beneficial effects of this utility model are:

[0018] 1. The filler and rear-loading compression garbage truck of the present invention for improving the stability of scraping materials have several longitudinally extending limiting blocks welded on the surface of the baffle plate of the filler, forming a guide track between the block and the parallel guide grooves. The block cooperates with the guide strip on the slide plate to constrain the lateral displacement freedom of the slide plate mechanism, avoid the slide plate from deviating in the vertical direction of the travel direction, reduce the occurrence of shaking, make the scraping and compression process more stable, and also avoid damage to the scraper and slide plate during long-term movement.

[0019] 2. Because there are multiple guide bars, guide grooves, and limit block components that are constrained and matched, the force is more evenly distributed, more durable, and maintenance is reduced. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] like Figure 1 As shown, a filler for improving scraping stability includes a housing 1, a baffle plate 2, a scraper 4, a hopper 5, and a sliding plate 3. The baffle plate 2 is fixed above the filler, and the sliding plate 3 moves back and forth relative to the baffle plate 2. When the sliding plate 3 moves, it drives the scraper 4 to move. The scraper 4 is driven to rotate by a hydraulic cylinder. When the sliding plate 3 drives the scraper 4 to move obliquely upward, it compresses the garbage in the hopper 5 and pushes it into the truck body.

[0028] like Figure 3 , 4 As shown, the lower end of the baffle plate 2 is provided with multiple evenly arranged guide grooves 202. Limiting blocks 201 are provided on both sides of the notches in the guide grooves 202. The limiting blocks 201 can be semi-enclosed blocks formed by bending stainless steel strips and having a parallelogram cross-section. The space between the limiting blocks 201 forms a guide channel with the guide grooves 202, which can be rectangular, U-shaped, or C-shaped. A guide bracket 204 can be connected to the lower end of the baffle plate 2. The guide bracket 204 is the same width as the baffle plate 2, and the limiting blocks 201 are mechanically connected or welded to the guide bracket 204. The upper surface of the baffle plate 2 is also provided with two or more reinforcing ribs 203, which are respectively connected to the limiting blocks 201.

[0029] like Figure 2 As shown, the lower surface of the slide plate 3 is provided with multiple evenly arranged guide strips 301. The guide strips 301 are arranged longitudinally and correspond one-to-one with the guide channels. The guide strips 301 are embedded in the guide channels formed by the guide grooves 202 and the limiting blocks 201 with clearance fit. The guide strips 301 and the lower surface of the slide plate 3 are of equal length in the moving direction. The guide strips 301 are long strips and are welded to the lower surface of the slide plate 3.

[0030] Example 2:

[0031] A rear-loading compression garbage truck with improved material scraping stability is disclosed, including a filler according to one embodiment.

[0032] The working principle of this utility model:

[0033] This invention creatively establishes a uniformly distributed rigid guide between the vertically cooperating baffle plate 2 and slide plate 3. This guide is achieved through multiple longitudinally evenly arranged guide strips 301 on the slide plate 3, guide grooves 202 on the baffle plate 2 that cooperate with the guide strips 301, and limiting blocks 201. This transforms the lateral force of the slide plate 3 mechanism under load into the supporting reaction force of the guide grooves 202, achieving dynamic load balance. This restricts the slide plate 3 mechanism to a single degree of freedom, eliminating lateral swaying and multi-directional vibration caused by uneven waste distribution. Consequently, abnormal friction and impact loads are reduced, the scraping action is more stable, and the lifespan of the slide plate 3, scraper 4, and hydraulic system is extended.

[0034] 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 the above embodiments are only for illustrating the technical concept and characteristics of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
