Description

Technical Field

[0001] The invention relates to the technical field of sanitation equipment, and more specifically to a foldable sanitation vehicle which is convenient for passing through narrow alleys. Background Art

[0002] Sanitation vehicles are a type of sanitation cleaning equipment. Sanitation vehicles are mostly used to clean the ground in cities, parks, communities, and shopping malls. Sanitation vehicles are divided into many types according to different functions, including sweeping the ground, washing the ground, and collecting garbage from trash cans. At present, most sanitation vehicles on the market can basically only meet the cleaning needs of large roads and wide roads. However, for the cleaning of narrow roads such as sidewalks and streets, most existing sanitation vehicles cannot be folded into some narrow sections. The vehicle body may be too wide, which may affect traffic safety. This will cause the garbage collection in some narrow alleys to be manually completed by sanitation workers, which is time-consuming and laborious. In view of this, the technicians in this field provide a foldable sanitation vehicle that is convenient for narrow alley passage to solve the problems raised in the above background technology. By designing a foldable sanitation vehicle, it can collect garbage in narrow alleys uniformly. The sanitation vehicle is used for collection, which is efficient and can reduce the labor intensity of sanitation workers, and is suitable for promotion.

[0003] In order to effectively clean some narrow alleys and collect and dispose of garbage, China Patent Network (CN218990028U) discloses a foldable sanitation vehicle, which includes a first frame, a first handle is provided at the upper end of the first frame, a connecting rod is provided at the lower end of the inner wall on both sides of the first frame, a first support rod is provided at the outer wall of the lower rear end of both sides of the first frame, and a second support rod is provided at the outer wall of the upper rear end of both sides of the first frame. The utility model is hingedly connected to the first frame and the second frame through the first support rod and the second support rod and the third support rod and the fourth support rod on both sides, and the other ends of the first support rod and the second support rod and the third support rod and the fourth support rod are hingedly connected to the first hinge block and the second hinge block, so that the device can achieve a foldable effect, so that it is convenient for sanitation workers to clean narrow sections of the road, and when it is necessary to make way, the folding device is used to avoid road congestion.

[0004] In order to avoid the sanitation vehicle being too large and inconvenient to pass, and at the same time being able to collect garbage in some narrow alleys in a unified manner, the China Patent Network (CN213922572U) discloses an electric three-wheeled sanitation vehicle with a folding plate. The utility model includes a frame and a driving seat. A storage box is provided on the frame behind the driving seat. A limit bracket is provided above the frame at the rear of the frame. The limit bracket is U-shaped and includes two arms and a connecting arm connecting the two arms. The two arms are fixed to the armrests on both ends of the driving seat by screws. An extension plate is provided at the lower end of the rear end of the frame and below the limit bracket. The extension plate is hinged to the lower end of the rear end of the frame; a contact arm is provided at the lower end of the end face of the extension plate opposite to the frame. The electric three-wheeled sanitation vehicle of the utility model can be used temporarily as a garbage loading vehicle, and the garbage can be transported by the electric three-wheeled sanitation vehicle, which reduces labor intensity and improves work efficiency. During the rest of the time, the expansion board can be folded up and the vehicle can be used as an electric three-wheeled sanitation vehicle for other purposes, so that one vehicle can be used for multiple purposes and the use function of the electric three-wheeled sanitation vehicle is increased.

[0005] The above two solutions still have some shortcomings in application. First, although the sanitation vehicle can be folded for easy passage, the length of narrow alleys varies. If it is pushed and pulled manually, the garbage collection efficiency is low and the labor intensity of sanitation workers is high, which cannot meet the actual needs. Second, when collecting garbage, the garbage in the garbage cans in the narrow alleys is usually poured onto the sanitation vehicle for unified collection. If the garbage cans are also taken away, there will be nowhere to put the garbage, and the process of putting the garbage cans back has to be added. Therefore, it is necessary to improve the structure of the sanitation vehicle so that it can be convenient for passage in some narrow alleys, and at the same time, it can quickly collect garbage, reduce the labor intensity of sanitation workers, and further improve the practicality of the sanitation vehicle.

[0019] The specific implementation of the present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 5 As shown, a foldable sanitation vehicle for convenient passage through narrow alleys includes a sanitation vehicle body 1, wherein the sanitation vehicle body 1 includes a cab 2 at the front and a frame at the rear, a garbage loading chamber 3 is provided on the top of the frame, and a "U"-shaped telescopic groove 4 is provided on the left and right sides and the upper and lower sides of the garbage loading chamber 3, and a folding chamber 5 is adaptively embedded in the telescopic groove 4, and telescopic cylinders 6 are provided on the left and right sides of the telescopic groove 4, and the driving end of the telescopic cylinder 6 is backward and connected to the folding chamber 5, and the folding chamber 5 can be folded forward and backward along the telescopic groove 4 through the telescopic cylinder 6, and a door body 7 is provided on the rear side of the folding chamber 5, and universal rollers 8 are provided on the left and right sides of the rear part of the folding chamber 5.

[0021] Furthermore, the frame is equipped with a hydraulic cylinder (not marked in the schematic diagram due to viewing angle reasons), and the garbage loading chamber 3 can be unloaded through the hydraulic cylinder.

[0022] Furthermore, oil pressure chambers 9 are installed on the left and right sides of the garbage loading chamber 3, and the oil pressure chambers 9 are connected to the oil inlet and the oil outlet of the telescopic cylinder 6 through pipelines.

[0023] Furthermore, the garbage loading chamber 3 is provided with an opening 31 at the top and a garbage bin turning frame 32 is provided at one side.

[0024] Furthermore, the two sides of the rear side of the folding cavity 5 are provided with hanging ears 51 , and the two sides of the top of the door body 7 are correspondingly provided with hooks, which are embedded in the hanging ears 51 .

[0025] Furthermore, spring grooves 52 are provided on the left and right sides of the rear part of the folding chamber 5, a telescopic rod 81 is provided on the top of the universal roller 8, a spring 10 is provided on the top of the telescopic rod 81, and the spring 10 is embedded in the spring groove 52. The universal roller 8 can be telescoped up and down through the spring 10. Example

[0026] First, the folding chamber 5 is folded in the telescopic groove 4, and the sanitation worker drives the sanitation vehicle body 1 to collect garbage. Since the cab 2 and the frame length of the sanitation vehicle body 1 are shorter than those of the existing sanitation vehicles, it can pass through narrow alleys conveniently. Then, when the garbage bin point is reached, the garbage bin is placed on the garbage bin turning frame 32, and the garbage bin is turned over by the garbage bin turning frame 32 to guide the garbage in the garbage bin into the garbage loading chamber 3 for unified collection. Then the sanitation vehicle body 1 continues to enter the next garbage point. Then, when the garbage in the garbage loading chamber 3 is full, the folding chamber 5 is pulled out of the telescopic groove 4 by the telescopic cylinder 6. The slot 4 is partially unfolded backwards, and the volume of the garbage loading chamber 3 is expanded through this operation, which is convenient for pouring more garbage, avoiding the situation that the garbage cannot be loaded completely due to too much garbage during the garbage loading process, and the sanitation workers need to go back and forth many times, which is time-consuming and labor-intensive. Finally, after the garbage collection is completed, the sanitation vehicle body 1 is driven to the garbage recycling station, and the folding chamber 5 is retracted forward by the telescopic cylinder 6. Through this operation, the garbage in the folding chamber 5 is poured into the garbage collection pit, and then the hydraulic cylinder at the bottom of the frame is started to push the front side of the garbage loading chamber 3 upward, so that the garbage in the garbage loading chamber 3 is poured into the garbage collection pit, completing the dumping of the garbage.

[0027] It can be seen from the above description of the present invention that, compared with the prior art, the advantages of the present invention are: The present invention firstly arranges a cab and a frame through a sanitation vehicle body, and a garbage loading chamber is arranged on the frame. Compared with the existing sanitation vehicles, the present invention is short in length and small in size, which is convenient for passing through narrow alleys and collecting garbage; then, a telescopic slot is arranged in the garbage loading chamber, and a folding chamber is built in the telescopic slot, and the folding chamber can be telescopically folded forward and backward along the telescopic slot by a telescopic cylinder. When a lot of garbage is encountered, the folding chamber part can be unfolded backward to increase the volume, which is convenient for loading the garbage, and the unfolding length can be set according to actual conditions, so as to avoid affecting the passage and increase the garbage loading amount; finally, retractable universal rollers are arranged on both sides of the rear part of the folding chamber. When the folding chamber is unfolded, the universal rollers can prevent the vehicle body from tilting or tilting. When the garbage loading chamber is unloading the bucket, the universal rollers can prevent the universal rollers from pressing against the ground and causing the bucket to be unable to be unloaded. The present invention has a novel structure and a clever design, and can be easily folded. It can not only pass through narrow alleys, but also increase the garbage loading amount. It is very practical and has high safety, and is suitable for promotion.

[0028] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial improvement of the present invention using this concept should be regarded as an infringement of the protection scope of the present invention.
