[0030] The following is a further detailed description of the specific implementation mode of the present utility model by describing the optimal embodiment with reference to the attached drawings.

[0031] A garbage truck scraper includes a scraper panel 1 and a reinforcement mechanism on the scraper panel 1; the reinforcement mechanism includes a support beam 2 arranged on the scraper panel 1; through the setting of the reinforcement mechanism, the overall structural strength of the garbage truck scraper is greatly guaranteed, thereby effectively increasing the service life of the garbage truck scraper.

[0032] The garbage truck scraper disclosed in the present utility model mainly optimizes the existing scraper structure.

[0033] The garbage truck scraper disclosed in the present utility model mainly includes a scraper panel 1. In the present utility model, the scraper panel 1 is integrally in an arc-shaped plate structure. Such a setting, on the one hand, facilitates the storage, transportation, and compression of garbage during the work cycle; on the other hand, it increases the stress intensity of the scraper panel 1 during compression; in addition, there is a reinforcement mechanism on the scraper panel 1 in the present utility model; the reinforcement mechanism is essentially a reinforcing rib structure, mainly to ensure the overall structural strength of the scraper panel 1; specifically, in the present utility model, the reinforcement mechanism includes a support beam 2 arranged on the scraper panel 1; in the present utility model, the support beam 2 is integrally a frame structure, and its essential function is to increase the overall structural strength of the scraper panel 1, thereby realizing the overall structural strength of the garbage truck scraper.

[0034] Further, in the present utility model, a wear-resistant layer is provided on the scraper panel 1; the wear-resistant layer is mainly to increase the wear resistance of the scraper panel 1 and ensure its service life. In actual arrangement, the wear-resistant layer and the reinforcement mechanism are distributed on opposite sides of the scraper panel 1.

[0035] Further, in the present utility model, the support beam 2 includes a front support beam 21, a middle support beam 23, and a rear support beam 22 arranged on the scraper panel 1; the front support beam 21 and the rear support beam 22 are arranged at intervals; the front support beam 21 and the rear support beam 22 are connected by the middle support beam 23; the front support beam 21 and the rear support beam 22 are distributed at the edges of the scraper panel 1, mainly to increase the structural strength at the edges of the scraper panel 1, and there are multiple middle support beams 23 on the scraper panel 1 and they are arranged at intervals and in parallel, and at the same time, both ends of the middle support beam 23 are respectively connected to the front support beam 21 and the rear support beam 22. Such a setting ensures the integrity of the support beam 2 and also facilitates the overall arrangement and placement of the support beam 2 on the scraper panel 1.

[0036] Furthermore, in the present utility model, weight-reducing holes 24 are provided on the front support beam 21, the middle support beam 23, and the rear support beam 22; the basic function of the weight-reducing holes 24 is to reduce the weights of the front support beam 21, the middle support beam 23, and the rear support beam 22, thereby reducing the weight of the entire scraper assembly and making a certain contribution to the lightweight of the upper loading of the whole vehicle during subsequent use.

[0037] Meanwhile, in the present utility model, the vertical cross-sections of the front support beam 21, the middle support beam 23, and the rear support beam 22 are trapezoidal; such a trapezoidal design of the front support beam 21, the middle support beam 23, and the rear support beam 22 can increase the contact area between the support beam 2 and the scraper panel 1 to a certain extent, which is beneficial to ensuring the stability of the connection between the support beam 2 and the scraper panel 1. At the same time, in the present utility model, the front support beam 21, the middle support beam 23, and the rear support beam 22 are all of an internally hollow structure. Such a setting can reduce the weights of the front support beam 21, the middle support beam 23, and the rear support beam 22 while ensuring their own structural strength.

[0038] A garbage truck scraper assembly includes a garbage truck scraper; an ear plate mechanism 3 is provided at the end of the garbage truck scraper; through the setting of the strengthening mechanism, the structural strength of the garbage truck scraper disclosed in the present utility model is relatively large, which greatly ensures the service life of the garbage truck scraper assembly. At the same time, through the setting of the ear plate mechanism 3 in the present utility model, it is convenient to be subsequently connected to the slide plate mechanism in the garbage truck.

[0039] In addition, in the present utility model, the ear plate mechanism 3 includes an ear plate body 3-1, and the ear plate body 3-1 includes two outer plate bodies 31 arranged oppositely; the two outer plate bodies 31 are connected by a scraper pin sleeve 34; the two outer plate bodies 31 are spaced apart, and a scraper pin sleeve 34 is provided at the middle position. Based on such a setting, the two outer plate bodies 31 serve as the main structure of the ear plate body 3-1, which facilitates the subsequent external connection operation of the ear plate mechanism 3. And in the present utility model, the scraper pin sleeve 34 serves as a connecting piece, which is convenient to be connected to the pin in the slide plate mechanism.

[0040] Furthermore, in the present utility model, a reinforcing plate body 32 is provided on each outer plate body 31; through the setting of the reinforcing plate body 32 in the present utility model, the overall structural strength of the outer plate body 31 is greatly ensured, and thus the overall structural strength of the ear plate body 3-1 is ensured.

[0041] Furthermore, in the present utility model, the two outer plate bodies 31 are also connected by side sealing plates. The side sealing plates include an inner straight sealing plate 33 and an inner bent sealing plate 36 disposed on the side of the outer plate body 31 away from the scraper panel 1. The two opposite sides of the inner bent sealing plate 36 are respectively attached to the inner walls of one outer plate body 31. One end of the inner bent sealing plate 36 is connected to the inner straight sealing plate 33, and the other end extends to the scraper pin sleeve 34. In the present utility model, the inner straight sealing plate 33 and the inner bent sealing plate 36 are arranged in the area between the two outer plate bodies 31, mainly for sealing the area not in contact with the scraper panel 1. At the same time, the side sealing plates also act as a strengthening member, which can ensure the structural strength of the ear plate body 3-1 to a certain extent.

[0042] In addition, in the present utility model, the ear plate body 3-1 is attached to the scraper panel 1. Generally, the ear plate mechanism 3 is arranged at the end of the scraper panel 1. At the same time, in the present utility model, the two ends of the support beam 2 respectively press against the ear plate mechanisms 3 at the two ends of the scraper panel 1. Based on such a setting, the end of the support beam 2 and the ear plate mechanism 3 are in mutual pressing contact. During subsequent installation, the support beam 2 can also be connected to the ear plate mechanism 3. Such a setting makes one function of the ear plate mechanism 3 convenient for the subsequent installation and connection of the scraper assembly, and the other function is that the ear plate mechanism 3 and the support beam 2 can jointly bear the role of increasing the strength of the scraper panel 1.

[0043] Specifically:

[0044] The present utility model discloses a scraper assembly for a garbage truck, mainly including a garbage truck scraper. This scraper is installed in the filler of a rear-loading self-unloading compression garbage truck, and is connected to the slide shaft in the filler through two lower holes in the ear plate of the scraper, and is connected to the working oil cylinder shaft through two upper holes in the ear plate of the scraper.

[0045] Its main function is to act together with the slide plate in the filler to scrape domestic garbage into the compartment of the garbage truck.

[0046] For a rear-loading compression garbage truck, the rear filler is an important component of the upper installation.

[0047] The scraper and slide plate mechanism in the filler are the main structural components for garbage transportation, crushing, and compression.

[0048] According to the movement mode and force analysis of the scraper in the filler, the scraper panel 1 of the scraper is designed in an arc form. On the one hand, it is convenient for garbage storage, transportation, and compression during the working cycle; on the other hand, it increases the force-bearing strength of the scraper panel 1 during compression.

[0049] The material of the scraper panel 1 uses high-strength wear-resistant steel and is sprayed with a wear-resistant coating, thereby reducing the weight of the scraper panel 1.

[0050] The back of the scraper panel 1 is supported by a support beam 2 with a high-strength steel trapezoidal cross-section behind the arc-shaped panel, which increases the stress-bearing strength of the scraper panel 1. Moreover, the support beam 2 is provided with weight-reducing holes 24 to further reduce the weight of the component. On the sides of the scraper panel 1, left and right ear plate mechanisms 3 are welded according to the arc of the panel. The ear plate mechanism 3 and the scraper panel 1 have an arc-shaped joint surface, and holes are left on the ear plates to be connected to the shaft of the working oil cylinder and the rotating part of the slide plate.

[0051] The hanging plate assembly disclosed above in the utility model not only ensures the strength of the working part, but also reduces the weight of the scraper assembly through the optimized structure and the use of high-strength materials; compared with similar products, the weight reduction exceeds 1 / 3.

[0052] During actual design, according to the internal volume of the filler of the rear-loading garbage truck and the running trajectories of the scraper and the slide plate, the size of the scraper panel 1 that meets the requirements is designed. The scraper panel 1 is of an arc-shaped structure, which is convenient for garbage collection on the one hand and increases the working stress-bearing strength of the scraper panel 1 on the other hand. Since the inner surface of the arc-shaped panel often rubs against domestic garbage and the working environment is long-term in complex environments such as acid, alkali, and humidity, high-strength and high-toughness wear-resistant materials are used, and a wear-resistant and anti-corrosion coating is sprayed on the surface of the wear-resistant materials.

[0053] Compared with ordinary steel materials, the high-strength wear-resistant and anti-corrosion materials mainly ensure that the stress-bearing strength is not affected, and at the same time lighten the parts.

[0054] The use of the support beam 2 with a trapezoidal cross-section shape is welded and fixed with the front support beam 21, several middle support beams 23, and the rear support beam 22 successively behind the scraper panel 1 from left to right as shown in the figure. The lower sides of the front and rear support beams 22 are respectively welded to the back of the panel, and the sides are welded and fixed to the ear plate mechanisms 3 on both sides. The above design increases the stress-bearing strength of the back of the arc-shaped panel.

[0055] At the same time, in order to reduce the weight of the support beam 2 itself, after force analysis and actual case tests, the weight of the part itself is reduced by using weight-reducing process holes without affecting the strength.

[0056] On the left and right sides of the scraper panel 1, the ear plate mechanism 3 is welded and fixed. The ear plate mechanism 3 mainly includes two symmetrically arranged outer plate bodies 31. Reinforcing plate bodies 32 are arranged in each outer plate body 31, and the edges of the outer plate bodies 31 are connected by side sealing plates. The side sealing plates mainly include an inner straight sealing plate 33 and an inner bent sealing plate 36; a nut seat is provided on the inner straight sealing plate 33, and a grease nipple sheath 35 is provided on the scraper pin bushing 34.

[0057] Since the welded parts of the ear plate mechanism 3 are all assembled by high-strength steel plates, the blanking and synthesis processes are relatively simple. The inner and outer plate bodies 31 are assembled by welding high-strength steel plates to form a structure with a reinforcing plate in the middle. The arc surfaces of the inner and outer ear plates are welded to the arc surface of the scraper panel 1, and the strength after welding is sufficient to meet the high-strength working requirements of the garbage truck scraper.

[0058] The scraper assembly is connected to the pin shaft of the slide plate mechanism through the scraper pin shaft sleeve 34 in the left and right ear plate mechanisms 3 as the rotation fulcrum. At the same time, a working oil cylinder is also connected when the ear plate mechanism 3 is actually connected. In subsequent use, it can rotate around the pin shaft sleeve hole under the drive of the working oil cylinder to scrape the garbage in the hopper of the compression type garbage truck filler; then, during the upward sliding of the slide plate, the garbage in the scraper is sent into the rear-loading garbage bin.

[0059] Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantial improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
