Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, and in particular to a garbage collection vehicle that is easy to load. Background Technology

[0002] Currently, garbage is frequently generated in daily life, and garbage collection and transportation largely require the use of garbage trucks. Garbage trucks are mainly used for the collection and transportation of various types of garbage by municipal sanitation departments, especially residential garbage. Existing garbage trucks generally include a vehicle body, a collection box, and a hydraulic system. The collection box is rotatably installed at the rear of the vehicle body and is used to store garbage. The hydraulic system is used to drive the end of the collection box away from the front of the vehicle to rotate upwards, so as to empty the garbage from the collection box.

[0003] With the acceleration of urbanization, the operational efficiency and environmental performance of garbage collection trucks have become core challenges for sanitation systems. Traditional garbage collection trucks generally suffer from the following drawbacks: high reliance on manual labor, with garbage bin loading and unloading entirely dependent on manual handling, requiring operators to lift the bins to the top of the truck bed before emptying. Statistics show that each operation is time-consuming, and prolonged operation can easily lead to muscle strain. While existing semi-automatic models use hydraulic lifting mechanisms, they have significant shortcomings: the tipping mechanism relies on an independent motor drive, resulting in high energy consumption and a high failure rate; the cover requires separate pneumatic control, and misalignment with the lifting sequence can easily lead to garbage spillage or odor leakage. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a garbage collection vehicle that is easy to load.

[0005] The technical solution of this utility model is a garbage collection vehicle that is easy to load, comprising:

[0006] Garbage truck, the garbage truck has a cargo box installed on the frame, and the top of the cargo box has a feeding port;

[0007] A cover plate is rotatably mounted on the upper end of the carriage, and a first cylinder for driving the cover plate to rotate is installed on the carriage.

[0008] The lifting mechanism includes a rotating plate and two sliding rods. The two sliding rods are arranged side by side on one side of the carriage and are fixedly connected to the carriage. Rotary seats are slidably installed on the sliding rods along their length. Vertical sliding holes are opened on the sliding rods. Rotary plates are connected to rotating shafts at both ends. The two rotating shafts pass through the vertical sliding holes on both sides and are rotatably installed on the rotating seats on both sides. A first connecting rod is rotatably connected between the cover plate and the two rotating seats.

[0009] Two sets of automatic tilting components, each including a rack and a gear, with the gear mounted on a rotating shaft and the rack vertically connected to one side of the carriage;

[0010] A clamping device is mounted on a rotating plate.

[0011] Preferably, the clamping device includes two sets of clamping components, which are symmetrically arranged. Each clamping component includes an L-shaped clamping rod, a third cylinder, a slider, and a second connecting rod. The end of the L-shaped clamping rod is rotatably mounted on a rotating plate. A transverse sliding hole is provided on the rotating plate. The slider is slidably mounted inside the transverse sliding hole. The two ends of the second connecting rod are rotatably connected to the slider and the L-shaped clamping rod, respectively. The third cylinder is mounted on the rotating plate and its output shaft is connected to the slider.

[0012] Preferably, a support plate is connected to the bottom end of the rotating plate.

[0013] Preferably, a vertical rod is provided on the back of the rotating plate, and the vertical rod is connected to the carriage.

[0014] Preferably, the rear of the carriage is open, a flap is rotatably mounted at the rear of the carriage, and a second cylinder is installed on the carriage to drive the flap to rotate.

[0015] Preferably, the shaft, gear, rack, and first connecting rod are all made of high-strength alloy material.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] 1. This technical solution automatically fixes the trash can through a clamping device, lifts it through a lifting mechanism, and triggers the tipping and unloading steps by gear and rack engagement. The entire process requires no manual intervention, greatly improving work efficiency.

[0018] 2. When the rotating seat rises to the top of the slide bar, the gear and the fixed rack are forced to mesh, driving the rotating shaft to rotate the rotating plate, which mechanically and automatically flips, reducing energy consumption.

[0019] 3. When the first cylinder drives the cover plate to flip upward, it pulls the rotating seat along the slide rod through the first connecting rod, which simultaneously triggers the lifting action of the trash can, so that the opening and lifting actions are strictly synchronized, and the unloading process does not require separate operation of the cover plate.

[0023] Example 1

[0024] like Figures 1-3 As shown in the figure, the garbage truck proposed in this embodiment is easy to load and includes a garbage truck 1, a cover plate 4, a lifting mechanism, a clamping device and two sets of automatic tipping components.

[0025] Garbage truck 1 has a cargo box 2 mounted on its frame. It should be noted that the cargo box 2 is rotatably mounted on the frame of garbage truck 1. A hydraulic cylinder for driving the rotation of the cargo box 2 is mounted on the frame. The above structure is a common garbage truck unloading structure and is publicly available technology, so it will not be described in detail. The top of the cargo box 2 has a feed inlet. The rear of the cargo box 2 is open. A flap 3 is rotatably mounted on the rear of the cargo box 2. A second cylinder 10 for driving the flap 3 to rotate is mounted on the cargo box 2. The second cylinder 10 is rotatably mounted on the cargo box 2, and its output shaft is hinged to the flap 3.

[0026] The cover plate 4 is rotatably mounted on the upper end of the carriage 2. The carriage 2 is equipped with a first cylinder 5 for driving the cover plate 4 to rotate. The first cylinder 5 is rotatably mounted on the carriage 2, and its output shaft is hinged to the cover plate 4.

[0027] The lifting mechanism includes a rotating plate 7 and two sliding rods 6. The two sliding rods 6 are arranged side by side on one side of the carriage 2 and are fixedly connected to the carriage 2. A rotating seat 15 is slidably installed on the sliding rod 6 along its length. A vertical sliding hole 601 is opened on the sliding rod 6. A rotating shaft 16 is connected to both ends of the rotating plate 7. The two rotating shafts 16 pass through the vertical sliding holes 601 on both sides and are rotatably installed on the rotating seats 15 on both sides respectively. A first connecting rod 18 is rotatably connected between the cover plate 4 and the two rotating seats 15. The two ends of the first connecting rod 18 are rotatably connected to the rotating seats 15 and the cover plate 4 respectively. A clamping device is installed on the rotating plate 7. The automatic tilting component includes a rack 11 and a gear 17. The gear 17 is installed on the rotating shaft 16, and the rack 11 is vertically connected to one side of the carriage 2.

[0028] A vertical rod 9 is provided on the back of the rotating plate 7, and the vertical rod 9 is connected to the carriage 2. It should be noted that the vertical rod 9 is provided to limit the state of the rotating plate 7 before it is flipped, so as to prevent the rotating plate 7 from causing a large amount of shaking in the initial stage of lifting and lowering. When the gear 17 and the rack 11 just come into contact, only the bottom back of the rotating plate 7 is in contact with the vertical rod 9.

[0029] It should be added that the rotating shaft 16, gear 17, rack 11, and first connecting rod 18 are all made of high-strength alloy materials.

[0030] The working principle of this technical solution is as follows:

[0031] Loading preparation: The operator places the garbage bin on the side of the rotating plate 7, with the cover plate 4 in the closed position, covering the feed inlet on the top of the compartment 2.

[0032] Clamping and fixing: The garbage can is automatically clamped and limited by a clamping device.

[0033] Drive lifting mechanism: The first cylinder 5 drives the cover plate 4 to flip upward around its hinge point. The cover plate 4 pulls the rotating seats 15 on both sides to slide upward along the slide rod 6 through the first connecting rod 18. The rotating seats 15 drive the rotating shaft 16 to rise in the vertical sliding hole 601, so that the rotating plate 7 and the garbage can held are lifted synchronously.

[0034] Tilting and unloading: When the rotating seat 15 rises to the upper position of the slide bar 6, the gear 17 on the rotating shaft 16 meshes with the rack 11 fixed on the side of the carriage 2. The gear 17 is forced to rotate by the rack 11, which drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the rotating plate 7 to tilt and dump the garbage can. The garbage falls into the carriage 2 through the feed port.

[0035] Emptying the garbage compartment: When the compartment 2 is full, the hydraulic cylinder on the frame drives the compartment 2 to tilt backward, and the second cylinder 10 drives the bottom of the flap 3 to tilt upward, expanding the unloading port, and the garbage pours out from the rear of the compartment 2.

[0036] In summary, this technical solution has the following advantages:

[0037] 1. The garbage bin is automatically fixed by the clamping device, lifted by the lifting mechanism, and the gear 17 and rack 11 engage to trigger the flipping and dumping of the material. No manual intervention is required throughout the process, which greatly improves the efficiency of operation.

[0038] 2. When the rotating seat 15 rises to the top of the slide bar 6, the gear 17 is forced to mesh with the fixed rack 11, driving the rotating shaft 16 to rotate the rotating plate 7, which mechanically and automatically flips over, reducing energy consumption.

[0039] 3. When the first cylinder 5 drives the cover plate 4 to flip upward, it pulls the rotating seat 15 along the slide rod 6 through the first connecting rod 18, which simultaneously triggers the lifting action of the garbage can, so that the opening and lifting actions are strictly synchronized, and the unloading process does not require separate operation of the cover plate.

[0040] Example 2

[0041] like Figures 1-3As shown, this embodiment proposes a garbage truck that is easy to load. Compared with the first embodiment, in this embodiment, the clamping device includes two sets of clamping components, which are symmetrically arranged. The clamping components include an L-shaped clamping rod 13, a third cylinder 19, a slider 20, and a second connecting rod 21. The end of the L-shaped clamping rod 13 is rotatably mounted on a rotating plate 7. A transverse sliding hole 701 is provided on the rotating plate 7. The slider 20 is slidably mounted inside the transverse sliding hole 701. The two ends of the second connecting rod 21 are rotatably connected to the slider 20 and the L-shaped clamping rod 13, respectively. The third cylinder 19 is mounted on the rotating plate 7 and its output shaft is connected to the slider 20. A support plate 8 is connected to the bottom end of the rotating plate 7.

[0042] In this embodiment, the bottom of the trash can is supported and positioned by the support plate 8. The third cylinder 19 pushes the slider 20 to slide horizontally along the transverse sliding hole 701. The slider 20 drives the L-shaped clamping rod 13 to rotate around its rotation point through the second connecting rod 21. The two sets of symmetrical L-shaped clamping rods 13 flip inward synchronously to clamp the trash can from both sides.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
