Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaning tools, and more specifically, to a new type of vacuum cleaning vehicle. Background Technology

[0002] Currently, roads in cities of all sizes in my country require a large amount of manpower for sweeping and dust removal, resulting in low cleaning efficiency. Many vacuum cleaners have emerged on the market to improve work efficiency by cleaning up garbage. However, current vacuum cleaners use a fan as their power source. The garbage and dust sucked in pass directly through the fan blades and are then discharged into a dust collection bag to achieve the suction function. When vacuuming road dust, the dust inevitably contains relatively large and hard debris such as pebbles and nails. This debris enters the fan with the airflow and collides with the rotating fan blades, damaging them and significantly shortening the fan's lifespan. Therefore, overcoming the shortcomings of the existing technology is a problem that urgently needs to be solved in this technical field. Utility Model Content

[0003] This utility model provides a new type of vacuum cleaner, which aims to improve the problem that road dust mixed with stones, nails, etc., enters the blower with the airflow and collides with the rotating fan blades, causing damage to the fan blades and greatly shortening the service life of the blower.

[0004] To achieve the above objectives, this utility model provides a novel vacuum cleaner cart, the specific technical solution of which is as follows: A novel vacuum cleaner vehicle includes a vehicle body, a vacuuming mechanism is provided on the front side of the vehicle body, the vacuuming mechanism is connected to a garbage separation mechanism, and the garbage separation mechanism is connected to a vacuum nozzle. Under the action of the vacuuming mechanism, garbage enters the garbage separation mechanism through the vacuum nozzle via airflow, and then the garbage is separated from the airflow in the garbage separation mechanism. Finally, the airflow is discharged through the vacuuming mechanism. The waste separation mechanism includes a first housing, with an air inlet pipe connected to the outside of the first housing. The air inlet pipe is inclined to the outer shell of the first housing. Airflow enters the interior of the first housing through the air inlet pipe and then flows spirally downward along the inner wall of the first housing. An air outlet pipe is provided inside the first housing, and a separation chamber is formed between the air outlet pipe and the first housing. The airflow carries the waste through the air inlet pipe into the separation chamber. Under the action of gravity, the waste leaves the separation chamber downward, and the airflow exits the first housing through the air outlet pipe and enters the dust collection mechanism.

[0005] In one embodiment, the vacuuming mechanism includes a second housing that communicates with a first housing. A driver is fixed to the outside of the second housing, and a fan blade is fixed to the output end of the driver. The fan blade is disposed inside the second housing.

[0006] In one embodiment, a waste collection mechanism is provided on the lower side of the waste separation mechanism. The waste collection mechanism includes a collection bucket, which is detachably disposed at the lower end of the first housing. Waste separated in the first housing falls into the collection bucket.

[0007] In one embodiment, a baffle cover is provided at the upper opening of the collection bin, and a through hole is provided in the middle of the baffle cover, through which garbage can pass into the collection bin.

[0008] In one embodiment, the suction nozzle is connected to the air inlet duct, and the waste enters the air inlet duct from the suction nozzle under the influence of airflow, and then enters the separation chamber in the first housing through the air inlet duct.

[0009] In one embodiment, a push-pull device is provided between the vacuum nozzle and the vehicle body, which enables the vacuum nozzle to move up and down, thereby adjusting the distance between the vacuum nozzle inlet and the ground.

[0010] In one embodiment, an air outlet is connected to one side of the second housing, and a dust collection bag is provided on the rear side of the vehicle body, with the inlet of the dust collection bag connected to the air outlet of the second housing.

[0011] In one embodiment, the vehicle body is provided with a water spraying mechanism, which includes a water tank installed on the vehicle body. A water pump is installed inside the water tank, and the water pump is connected to a nozzle through a water pipe. The nozzle is located inside the air intake duct. Under the action of the water pump, water from the water tank is input into the nozzle, and then sprayed from the nozzle onto the air intake duct. The sprayed water wets the dust flowing through the air intake duct.

[0012] In one embodiment, the vehicle body is provided with a power unit that provides power to the dust collection mechanism and the water spraying mechanism.

[0013] In one embodiment, the power unit is a storage battery.

[0014] The beneficial effects of this embodiment are: By setting a garbage separation mechanism at the inlet of the dust collection mechanism, dust, stones and other garbage enter the air intake duct from the dust collection nozzle under the action of the dust collection mechanism, and then enter the separation chamber inside the first housing from the air intake duct. The airflow carries the garbage to spiral downward along the inner wall of the first housing. Under the action of gravity and the centrifugal force of the airflow, the heavier garbage such as stones and iron nails in the airflow fall downward into the collection bucket below the first housing. Then the airflow enters from the inlet below the air outlet duct inside the first housing, and then enters the second housing along the air outlet duct. At this time, the stones and iron nails in the airflow have been separated, and only a small amount of dust remains. These entering the second housing cause very little damage to the fan blades, greatly improving the service life of the fan and achieving the separation of stones and other garbage from the dust. 2. By setting up a water spraying mechanism, the water pump delivers water from the water tank to the spray nozzle through the water pipe, and then the spray nozzle sprays water into the air intake duct. The water comes into contact with the dust flowing through the air intake duct, thereby achieving the dust removal effect. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] Please see Figure 1-11 This utility model provides a novel vacuum cleaner cart, including a vehicle body 100. A vacuuming mechanism 200 is provided at the upper front end of the vehicle body 100. Specifically, the vacuuming mechanism 200 includes a second housing 210. The lower end of the second housing 210 has an opening. A driver 220 is fixed to the outer side of the second housing 210 by bolts. The driver 220 can be a motor or an engine. A fan blade 230 is fixed to the end of the output shaft of the driver 220. The fan blade 230 is located in the middle of the interior of the second housing 210. The driver 220 drives the fan blade 230 to rotate, thereby accelerating the airflow inside the second housing 210, thereby generating negative pressure inside the second housing 210 and providing suction for vacuuming.

[0021] The lower end of the vacuuming mechanism 200 is connected to a garbage separation mechanism 300. Specifically, the garbage separation mechanism 300 includes a first housing 310, with openings at both the upper and lower ends. The upper opening of the first housing 310 is connected to the lower opening of the second housing 210, and the two are fixed together by bolts. An air inlet duct 311 is connected to the outside of the first housing 310. The air inlet duct 311 is inclined to the outer shell of the first housing 310. The optimal position is that the air inlet duct 311 is tangent to the outer shell of the first housing 310. At this time, the airflow enters the interior of the first housing 310 through the air inlet duct 311 and then flows spirally downward along the inner wall of the first housing 310. An air outlet duct 320 is provided inside the first housing 310. The upper end of the air outlet duct 320 is fixedly connected to the upper end of the first housing 310. The upper end of the air outlet duct 320 is tapered, wider at the top and narrower at the bottom (e.g., ...). Figure 7 As shown in the figure, this facilitates airflow convergence, increasing the airflow velocity after the airflow inside the first housing 310 enters the air outlet duct 320, thereby enhancing suction. A separation chamber 330 is formed between the air outlet duct 320 and the interior of the first housing 310. The airflow carries dust, stones and other debris into the separation chamber 330 through the air inlet duct 311. Under the action of gravity and centrifugal force of the airflow, the heavier debris such as stones falls downward and leaves the separation chamber 330. After the airflow flows to the lower side of the first housing 310, it enters from the air outlet duct 320, then flows upward along the air outlet duct 320, and finally enters the second housing 210 of the dust collection mechanism 200, and then is discharged from the second housing 210, thus realizing the separation of debris such as stones from the airflow.

[0022] The inlet of the air inlet duct 311 is connected to a suction nozzle 110 via an air pipe. The suction nozzle 110 is connected to the air inlet duct 311. Under the influence of the airflow, the garbage enters the air inlet duct 311 from the suction nozzle 110 and then enters the separation chamber 330 inside the first housing 310. Under the action of the suction mechanism 200, road dust and gravel are sucked into the garbage separation mechanism 300 by the airflow through the suction nozzle 110. Then, the gravel and other garbage are separated from the airflow in the garbage separation mechanism 300. Finally, the airflow is discharged through the suction mechanism 200. It should be noted that a push-pull device 120 is provided between the vacuum nozzle 110 and the vehicle body 100. The push-pull device 120 enables the vacuum nozzle 110 to move up and down, thereby adjusting the distance between the inlet of the vacuum nozzle 110 and the ground. When cleaning up garbage, push the push-pull device 120 downwards, the distance between the vacuum nozzle 110 and the road surface decreases, and then the vacuuming mechanism 200 starts to perform vacuuming. After vacuuming is completed, pull the push-pull device 120 upwards, the distance between the vacuum nozzle 110 and the road surface increases, preventing the vacuum nozzle 110 from colliding with other protruding objects on the road surface when the device moves, and facilitating the movement of the entire device.

[0023] A waste collection mechanism 400 is provided below the waste separation mechanism 300. The waste collection mechanism 400 includes a collection bin 410, which is detachably mounted at the lower end of the first housing 310 (a structure such as a buckle, latch, hook, or pin can be used to achieve detachment). When the vacuum truck is working, the airflow carries dust, stones, and other waste into the separation chamber 330 through the air inlet pipe 311. Under the action of gravity and centrifugal force of the airflow, heavier waste such as stones falls downwards, leaving the separation chamber 330 and falling into the collection bin 410 below, thus collecting the waste. After the work is completed, the collection bin 410 can be removed from the first housing 310, and the waste in the collection bin 410 can be emptied, greatly facilitating the dumping of waste. Preferably, a baffle cover 420 is provided at the upper opening of the collection bin 410. The baffle cover 420 is a conical design with a larger upper end and a smaller lower end (e.g., ...). Figure 9 As shown), a through hole 421 is provided in the middle of the baffle cover 420. The garbage in the first housing 310 can pass through the through hole 421 and enter the collection bin 410 through the baffle cover 420. The baffle cover 420 is designed to block the garbage entering the collection bin 410. Under the action of airflow, the garbage runs out of the collection bin 410 in the opposite direction, thus playing the role of baffle.

[0024] In addition, such as Figure 1 and 2 As shown, an air outlet 211 is connected to one side of the second housing 210, and a dust collection bag 130 is provided on the rear side of the vehicle body 100. The inlet of the dust collection bag 130 is connected to the air outlet 211 of the second housing 210. Dust is mixed in the airflow discharged from the second housing 210. The dust enters the dust collection bag 130 through the air outlet 211, thereby collecting the dust.

[0025] like Figure 10 and 11 As shown, preferably, the vehicle body 100 is provided with a water spraying mechanism 500, which includes a water tank 510. The water tank 510 is installed on the vehicle body 100, and a water pump 520 is installed inside the water tank 510. The water pump 520 is connected to a nozzle 530 through a water pipe. The nozzle 530 is installed inside the air intake duct 311. Under the action of the water pump 520, the water in the water tank 510 is input into the nozzle 530, and then sprayed from the nozzle 530 onto the air intake duct 311. The nozzle 530 is preferably an atomizing nozzle. The sprayed water wets the dust flowing through the air intake duct 311, thereby achieving the dust removal function. A power unit 140 is provided on the vehicle body 100. The power unit 140 is preferably a storage battery. The power unit 140 is electrically connected to the water pump 520 and the driver 220. The power unit 140 provides energy power to the dust collection mechanism 200 and the water spraying mechanism 500.

[0026] It should be noted that the motion state and trajectory of each mechanism in this device can be automatically controlled by CNC program or PLC programming, and automatic start-stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge to those skilled in the art, so they will not be described in detail here. The specific models and specifications of the power unit 140, driver 220 and water pump 520 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The power supply and principles of the power unit 140, the driver 220 and the water pump 520 are clear to those skilled in the art and will not be described in detail here.
