Description

Technical Field

[0001] The present 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, loading mechanism and other components. It is controlled by hydraulic and electrical systems to realize the function of collecting and transporting domestic garbage.

[0003] Conventional self-loading garbage trucks, such as Figure 1 As shown, there is no additional cover shielding device. To achieve the box sealing function, it relies on manually controlled scrapers. When compressed, they hover at the rear feeding port of the garbage bin, acting as a substitute for the top door. However, as a continuously moving component, the scraper maintains a certain distance from the garbage bin, which cannot provide complete shielding. After the garbage is fully loaded, some small pieces of garbage will still fall out during the transportation process of the vehicle, which is not a good overall effect.

[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 to achieve complete shielding to avoid secondary pollution during the transfer process. Summary of the Invention

[0005] The problem to be solved by the present invention is: in order to solve the problem that the existing technology cannot fully shield the garbage and some small pieces of garbage fall out, a self-loading and unloading garbage truck roof shielding device is provided.

[0006] The present invention is achieved through the following technical solution: a self-loading and unloading garbage truck roof covering device, comprising a top door, the top door comprising a profile frame and a panel attached to the outer surface of the profile frame, the profile frame being L-shaped and capable of fitting the shape of the rear end of the garbage truck bucket, the top door being provided with two first connecting ears and two second connecting ears, the first connecting ears being symmetrically arranged on either side of the upper plane of the top door, and the second connecting ears being oppositely arranged on either side of the inclined surface of the top door;

[0010] Furthermore, the outer surface of the scraper is a cylindrical surface and is provided with a rib plate. When the scraper 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 is located at the center or near the center of the scraper cylindrical surface, and a brush portion is installed on the panel of the top door.

[0011] Furthermore, the brush portion is detachably mounted on the top door.

[0012] Furthermore, the brush portion is fastened to the top door via a pressing plate and bolts.

[0013] Furthermore, the telescopic drive mechanism adopts an electric cylinder or an oil cylinder.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall 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 door 1 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 metal sheet, 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 end 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 truck bed 5, and the other end is rotatably connected to the second connecting ear 104; the lower part of the second connecting rod is bent and installed with a third connecting ear;

[0034] The telescopic drive 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-link mechanism, 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, realizing the opening and closing of the garbage truck top door 1, and the top door 1 swings greatly 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, so that small garbage will not fall 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. Then Figure 5 As shown, after loading the garbage, the scraper 6 moves to the rear end and hovers at the tail end of the bucket 5, and the electric cylinder drives the top door 1 to gradually close and has rotated a certain angle. Figure 6 As shown, the top door 1 has been 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 actual application, 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, as shown in FIG. 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 center of the cylindrical surface of the scraper 6. A brush portion 105 is installed on the panel 102 of the top door 1. 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, the brush portion 105 on the top door 1 will contact the cylindrical surface of the scraper 6, and brush the garbage on the outer surface of the scraper 6 from front to back, which has a self-cleaning effect. After using 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 end of the top door 1 is not provided with the brush portion 105, but is provided with a detachable silicone baffle, which can provide a more effective seal when the top door 1 is closed.

[0038] In actual application, 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 will not have small garbage falling from the gaps.
