[0001] The invention relates to the technical field of sanitation vehicles, and in particular to a roof shielding device for a self-loading and unloading garbage truck. Background Art

[0002] A self-loading and unloading garbage truck is a vehicle that is based on a Class II automobile chassis and is equipped with a garbage box, scraper, subframe, feeding mechanism and other components. It is controlled by hydraulic and electrical systems to collect and transport domestic garbage.

[0003] Conventional self-loading garbage trucks, such as Figure 1 As shown in the figure, there is no additional top cover shielding device. To achieve the box sealing function, the scraper must be manually controlled. When it is compressed, it hovers at the rear feeding port of the garbage box, which replaces the top door. However, as a continuously moving part, the scraper has a certain distance from the garbage box and cannot completely shield the garbage. After the garbage is fully loaded, some small pieces of garbage will still fall out during the vehicle's driving and transportation process, and the overall effect is not good.

[0004] Therefore, self-loading and unloading garbage trucks need a roof shielding device with independent control to meet market demand, without interfering with the original vehicle structure and achieving complete shielding to avoid secondary pollution during the transportation process.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 2-3 As shown, a roof shielding device for a self-loading and unloading garbage truck includes a top door 1, a first connecting rod 2, a second connecting rod 3, and a telescopic driving mechanism 4;

[0031] The top plate includes a profile frame 101 and a panel 102 attached to the outer surface of the profile frame 101. The frame is welded by channel steel and angle steel. The panel 102 is made of a metal sheet, which is sprayed with paint after surface treatment and sprayed with a pattern that matches the color tone of the main body of the garbage truck. The profile frame 101 is L-shaped, about 135°, and can fit the shape of the rear part of the garbage truck bucket 5. The top door 1 is provided with two first connecting ears 103 and two second connecting ears 104. The first connecting ears 103 are symmetrically arranged on both sides of the upper plane of the top door 1, and the second connecting ears 104 are arranged on both sides of the inclined surface of the top door 1;

[0032] The first connecting rod 2 is provided with two, one end of which is rotatably arranged on the side of the bucket 5, and the other end is rotatably connected to the first connecting ear 103;

[0033] The second connecting rod 3 is provided with two, one end of which is rotatably arranged on the side of the bucket 5, and the other end is rotatably connected to the first connecting ear 103; the lower part of the second connecting rod is bent and equipped with a third connecting ear;

[0034] The telescopic driving mechanism 4 adopts an electric cylinder, two of which are provided. The housing of the electric cylinder is rotatably mounted on the end of the side of the bucket 5, and the movable end of the electric cylinder is rotatably connected to the third connecting ear.

[0035] In this solution, the truck bed 5, the first connecting rod 2, the second connecting rod 3, and the top door 1 form a four-bar linkage, in which the truck bed 5 is a fixed part. Two electric cylinders simultaneously drive the second connecting rod 3 to rotate, which drives the top door 1 to rotate, thereby realizing the opening and closing of the garbage truck top door 1, and the top door 1 swings with the first connecting rod 2 and the second connecting rod 3, without causing interference with the scraper 6. In addition, the first connecting rod 2, the second connecting rod 3, and the electric cylinder are all installed on the side of the truck bed 5, and the top door 1 is installed on the top of the truck bed 5. They can all be installed additionally without interfering with the original vehicle structure, and can meet the vehicle's roof shielding requirements without small garbage falling through the gaps. The specific closing process is as follows: Figure 4-7 As shown, Figure 4 The top door 1 is fully opened, and the scraper 6 moves horizontally to the front end and rotates to the maximum angle. At this time, there is no interference between the scraper 6 and the top door 1. Figure 5 As shown in FIG. 1 , after the garbage is loaded, the scraper 6 moves to the rear end and hovers at the rear of the bucket 5, and the electric cylinder drives the top door 1 to gradually close and has rotated a certain angle. Finally, as shown in FIG. Figure 6 As shown, the top door 1 is completely closed and fits perfectly with the truck bed 5, so no small garbage will fall out. The main view is as follows: Figure 7 As shown, this solution can meet the vehicle's roof shielding requirements.

[0036] In practical applications, when the scraper 6 is scraping garbage for a long time, the outer surface of the scraper 6 will inevitably be stained with garbage. In order to facilitate the cleaning of the garbage on the outer surface of the scraper 6, Figure 2-3 As shown, the outer surface of the scraper 6 is a cylindrical surface and is provided with a rib plate. When the scraper 6 moves horizontally to the front end and rotates to open and close to the maximum angle, the rotation axis of the lower end of the second connecting rod 3 is located at the center or near the cylindrical surface of the scraper 6. A brush portion 105 is installed on the panel 102 of the top door 1, and the brush portion 105 is fastened to the top door 1 through a pressure plate 106 and bolts. Therefore, when the scraper 6 moves horizontally to the front end and rotates to open and close to the maximum angle, the top door 1 is closed at this time. At this time, the brush portion 105 on the top door 1 will contact the cylindrical surface of the scraper 6, and the garbage on the outer surface of the scraper 6 will be brushed off from front to back, achieving a self-cleaning effect. After being used for a period of time, the brush portion 105 can be removed for cleaning, or replaced with a new brush portion 105.

[0037] In another embodiment, the brush portion 105 is not installed at the end of the top door 1, but a silicone baffle is detachably installed. The silicone baffle can play a more effective sealing role when the top door 1 is closed.

[0038] In practical applications, in order to avoid interference, the profile frame 101 and the panel 102 are provided with notches for avoiding the scraper 6 .

[0039] In summary, the roof shielding device of a self-loading and unloading garbage truck described in the present invention does not interfere with the original vehicle structure, can meet the vehicle's roof shielding requirements, and small garbage will not fall through the gaps.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above implementation is only to illustrate the technical concept and features of the present invention, and its purpose is to enable people familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention.
