Description

Technical Field

[0001] The utility model relates to a compression type sewage collection device for a garbage truck, belonging to the technical field of sewage collection for garbage trucks. Background Art

[0002] Garbage trucks are mainly used to transport various types of garbage and are suitable for transporting residential domestic garbage. They are a type of sanitation equipment. Currently, garbage trucks, as special garbage vehicles, have played an increasingly important role in urban and rural garbage transportation, and the demand for garbage trucks is increasing.

[0003] There is often some sewage in the garbage in the garbage bin. When the garbage is poured into the compartment of the garbage truck, the sewage is poured into the compartment together. The actual situation is that the sewage flows out of the compartment and spills on the ground, which has a strong smell. Some garbage compartments in the prior art also have sewage collection devices, but because the compartment is full of compressed garbage, the sewage cannot be effectively collected. On the other hand, the sewage has a certain viscosity and sticks to the bottom of the compartment, making it difficult to flow.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] The utility model aims at the deficiencies in the background technology and provides a sewage collection device for a compression type garbage truck, which can smoothly collect sewage to the bottom of the car body and concentrate it into the middle sewage trough under the action of the bottom scraper, so that the sewage and sludge at the bottom of the car body can be discharged in a centralized manner.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A sewage collection device for a compression garbage truck, comprising a carriage, the bottom plate of the carriage comprising two V-shaped inclined panels, a sewage trough is provided in the middle of the two inclined panels, a filter plate is provided directly above the two inclined panels and arranged parallel to the two inclined panels, and a gap is left between the inclined panels and the filter plate;

[0008] A plurality of supporting vertical plates are arranged in the gap between the inclined plate and the filter plate to support the filter plate.

[0009] Furthermore, each inclined panel is provided with a plurality of downwardly sunken grooves at equal intervals, the grooves are arranged perpendicularly to the sewage trough, and the grooves are communicated with the sewage trough.

[0010] Furthermore, the lower end of the supporting vertical plate is fixed at the middle position of the bottom of the groove, and the upper end is fixedly connected to the ground of the filter plate.

[0011] Further, a scraper is provided between every two adjacent grooves. A pull rod is provided above each inclined panel, and the pull rods fixedly connect the scrapers on the inclined panels together. The pull rod penetrates through the supporting vertical plate. When the pull rod slides along its axial direction, it drives the scraper to slide between two adjacent grooves, thereby scraping the sewage and sludge between the two grooves into the grooves.

[0012] Further, a connecting rod is provided at the position where the two pull rods are close to the front end of the carriage. The connecting rod fixedly connects the two pull rods. The connecting rod extends to both sides of the carriage. Threaded nuts are installed on the threaded rods respectively rotatably provided on both sides of the carriage. The nuts are fixedly connected to the connecting rod. A first helical gear is fixed at the front end of the threaded rod. The first helical gear meshes and drives with a second helical gear. A transmission shaft is installed between the two second helical gears. The transmission shaft is driven by a driving mechanism.

[0013] Further, the bottom of the sewage tank is an arc-shaped filter screen, and a conveying auger is provided in the sewage tank.

[0014] Further, an end cover is provided at the front end of the sewage tank. The conveying auger is connected to a crank. When discharging sludge, the end cover is removed, and the crank is shaken to discharge the sludge in the sewage tank.

[0015] Further, a water receiving tank is provided along the length direction of the bottom of the sewage tank, and a drain valve is provided at the bottom of the water receiving tank.

[0016] After the present utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0017] 1. Filter plates are provided directly above the two inclined panels and are arranged parallel to them. A gap is left between the inclined panel and the filter plate, enabling sewage and sludge to flow vertically and smoothly down into the gap between the filter plate and the inclined panel; a plurality of downwardly concave grooves are equidistantly provided on each inclined panel, and a scraper is provided between the grooves. When the pull rod slides along its axial direction, it drives the scraper to slide between two adjacent grooves, thereby scraping the sewage and sludge between the two grooves into the grooves. When a large amount of sewage and sludge accumulates in the grooves, it is convenient for them to flow into the sewage tank.

[0018] 2. Sewage can pass through the filter screen and leak into the water receiving tank and be discharged through the drain valve; sludge with a relatively high viscosity deposits in the sewage tank. When discharging sludge, the end cover is removed, and the crank is shaken to discharge the sludge in the sewage tank, thereby discharging sewage and sludge separately.

Specific embodiments

[0026] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0027] As Figures 1-4 shown, the present utility model provides a sewage collection device for a compression-type garbage truck, including a carriage 1. The vehicle floorboard 101 of the carriage 1 includes two V-shaped inclined panels. A sewage tank 8 is provided in the middle of the two inclined panels. A filter plate 2 parallel to the inclined panels is provided directly above the two inclined panels, and a gap is left between the inclined panels and the filter plate 2.

[0028] A plurality of supporting vertical plates 3 are provided in the gap between the inclined panel and the filter plate 2 to support the filter plate 2.

[0029] A plurality of downwardly concave grooves 4 are equidistantly provided on each inclined panel. The grooves are perpendicular to the sewage tank 8 and are in communication with the sewage tank 8.

[0030] The lower end of the supporting vertical plate 3 is fixed at the middle position of the bottom of the groove 4, and the upper end is fixedly connected to the ground of the filter plate 2.

[0031] A scraper 5 is provided between every two adjacent grooves 4. A pull rod 6 is provided above each inclined panel. The pull rod 6 fixedly connects the scrapers 5 on the inclined panel together. The pull rod 6 passes through the supporting vertical plate 3. When the pull rod 6 slides along its axial direction, it drives the scraper 5 to slide between every two adjacent grooves 4, thereby scraping the sewage and sludge between the two grooves 4 into the groove 4.

[0032] Two pull rods 6 are provided with a connecting rod 7 near the front end of the carriage 1. The connecting rod 7 fixedly connects the two pull rods 6. The connecting rod 7 extends to both sides of the carriage 1. Threaded rods 12 are rotatably provided on both sides of the carriage 1. Nuts 13 are threadedly installed on the threaded rods 12. The nuts 13 are fixedly connected to the connecting rod 7. A first helical gear 14 is fixed to the front end of the threaded rod 12. The first helical gear 14 meshes and drives with a second helical gear 15. A transmission shaft 16 is installed between the two second helical gears 15. The transmission shaft is driven by a driving mechanism 17.

[0033] The bottom of the sewage tank 8 is an arc-shaped filter screen 18. A conveying auger 9 is provided in the sewage tank 8.

[0034] A end cover 10 is provided at the front end of the sewage tank 8. The conveying auger 9 is connected to a crank 11. When discharging sludge, the end cover 10 is removed, and the crank 11 is shaken to discharge the sludge in the sewage tank 8.

[0035] A water receiving tank 19 is provided along the length direction of the bottom of the sewage tank 8. A drain valve 20 is provided at the bottom of the water receiving tank 19.

[0036] The specific working principle of the present utility model:

[0037] A filter plate 2 is provided above the inclined panel of the carriage 1. The compressed garbage is piled up above the filter plate 2. The compressed sewage and sludge flow onto the inclined panel after passing through the filter plate 2, so that the sewage and sludge can smoothly flow vertically down into the gap between the filter plate 2 and the inclined panel. A plurality of downwardly concave grooves 4 are equidistantly provided on each inclined panel, and the grooves 4 are communicated with the sewage tank 8. A scraper 5 is provided between each two grooves 4. A pull rod 6 is provided above each inclined panel. When the pull rod 6 slides along its axial direction, it drives the scraper 5 to slide between two adjacent grooves 4, thereby scraping the sewage and sludge between the two grooves 4 into the grooves 4. Since the sewage and sludge have a certain viscosity and are not easy to flow downward, the scraper 5 scrapes the sewage and sludge together into the grooves 4. When a large amount of sewage and sludge are concentrated in the grooves 4, it is convenient to flow into the sewage tank 8.

[0038] The sewage can leak through the filter screen 18 into the water receiving tank 19 and be discharged through the drain valve 20. The sludge with a relatively high viscosity is deposited in the sewage tank 8. When discharging the sludge, the end cover 10 is removed, and the crank 11 is shaken to discharge the sludge in the sewage tank 8, so that the sewage and sludge are discharged separately.

[0039] The above is an example of the best implementation mode of the present utility model. The parts not described in detail are all common general knowledge of those skilled in the art. The protection scope of the present utility model is subject to the content of the claims. Any equivalent transformation based on the technical inspiration of the present utility model is also within the protection scope of the present utility model.
