[0032] The following further elaborates the present invention in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the protection scope of the present invention. In actual applications, the improvements and adjustments made by those skilled in the art according to the present invention still fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] As Figure 1 shown, a garbage collection device includes a negative pressure box 401 and a positive pressure box 402. The negative pressure box 401 is sleeved outside the positive pressure box 402. The negative pressure box 401 is connected to a negative pressure suction head 1 through a first pipeline 201, and the negative pressure suction head 1 is connected to a rotary brush. The negative pressure box 401 is connected to a fan 3 through a second pipeline 203. When the fan 3 operates, a negative pressure is formed in the negative pressure box 401 to generate suction. The first pipeline 201 is arranged on the side of the upper part of the negative pressure box 401, and the second pipeline 203 is arranged on the top of the negative pressure box 401 to form a first exhaust port 2031; there are two first exhaust ports 2031, which are symmetrically arranged on the top of the negative pressure box 401. A net plate 8 is arranged at the first exhaust port 2031 to prevent the garbage in the negative pressure box 401 from entering the second pipeline 203 along with the air flow. Figure 1 The size and shape of the negative pressure box 401 shown are not used to limit the present invention, and a suitable negative pressure box can be designed according to the size and working conditions of the sweeper.

[0035] The positive pressure box 402 is connected to a third pipeline 202, as Figure 2As shown, the direct-through pipe pickup mechanism 6 has three interfaces, namely interfaces 601, 602, and 603. Interface 602 is connected to the third pipe 202, interface 601 is connected to the fourth pipe 204, and interface 603 is connected to the blower 3. The air outlet of the blower 3 blows air into the direct-through pipe pickup mechanism 6 and the air enters the third pipe 202. A positive pressure is formed in the third pipe 202 and inside the positive pressure box, and then a negative pressure is formed in the fourth pipe 204, and the fourth pipe 204 becomes a negative pressure suction head. A second exhaust port 5 is provided at the top of the positive pressure box 402. The third pipe 202 and the fourth pipe 204 connected to the direct-through pipe pickup mechanism 6 are straight-through pipes, which are convenient for cleaning garbage with a relatively large volume or mass on the ground. Figure 1 The size and shape of the shown positive pressure box 402 are not used to limit the present invention. It only needs to ensure that the positive pressure box 402 can match the size of the negative pressure box 401 so that the positive pressure box 402 can be sleeved inside the negative pressure box 401.

[0036] Preferably, the positive pressure box 402 is sleeved inside the negative pressure box 401, and the side wall of the positive pressure box 402 does not contact the negative pressure box 401, and an annular space is formed inside the negative pressure box 401. When the blower 3 operates, negative pressures are formed in different directions inside the negative pressure box 401, and the air inside the negative pressure box 401 forms airflows in different directions under the drive of the negative pressure. The airflows rotate around the positive pressure box 402 in the limited annular space to form spiral airflows. After the garbage enters the negative pressure box 401, it sinks to the bottom of the negative pressure box 401 along the positive pressure box 402 under the drive of the spiral airflows, and the air is discharged from the first exhaust port 2031. The spiral airflows effectively enhance the suction force of the negative pressure suction head. The positive pressure suction head 204 and the negative pressure suction head 1 of the present invention can be driven by one blower or by two blowers respectively.

[0037] Preferably, the positive pressure box 402 is arranged in a shape that is narrower at the top and wider at the bottom. The second pipe 203 extends into the negative pressure box 401 from the top of the negative pressure box 401 and fits the positive pressure box 402 for a certain distance to form the first exhaust port 2031. Such an irregular shape can further stir the airflows inside the negative pressure box 401.

[0038] Preferably, the present invention does not specifically limit the number of the first exhaust ports 2031. It can be multiple, or the second pipe 203 extends into the negative pressure box 401, and the first exhaust port is formed by several extended parts closely surrounding the positive pressure box 402. Preferably, a mesh structure 2032 is arranged around the end of the first exhaust port 2031 for preventing the garbage inside the negative pressure box 401 from entering the mesh plate 8 of the first exhaust port 2031 and causing the mesh plate 8 to be blocked.

[0039] In a preferred embodiment, for the convenience of dumping the garbage in the box body, the bottoms of the positive pressure box 402 and the negative pressure box 401 are detachable, and the bottom 403 of the positive pressure box 402 and the negative pressure box 401 is connected to the box body by means of hinge. Opening the bottom 403 of the positive pressure box 402 and the negative pressure box 401 can achieve the unloading of the garbage. In this embodiment, the positive pressure box 402 and the negative pressure box 401 share a bottom 403, and opening the bottom 403 can achieve the unloading of the garbage in the positive pressure box 402 and the negative pressure box 401. In another embodiment of this embodiment, there is a distance between the bottom of the positive pressure box 402 and the bottom of the negative pressure box 401. When the positive pressure box 402 is full, the bottom of the positive pressure box 402 can be opened, and the garbage in the positive pressure box 402 can be unloaded into the negative pressure box 401.

[0040] In another preferred embodiment, for the convenience of connecting the third pipeline 202 to the positive pressure box 402 and increasing the capacity of the positive pressure box 402, the positive pressure box 402 is higher than the negative pressure box 401, and the third pipeline 202 is arranged on the part where the positive pressure box 402 is higher than the negative pressure box 401.

[0041] In another preferred embodiment, in order to prevent the airflow in the positive pressure box 402 from driving the dust out of the second exhaust port 5, a baffle 501 is arranged on the second exhaust port 5, and the baffle 501 is set in a shape with a higher middle and lower sides. In another preferred embodiment, the second exhaust port 5 is an independent exhaust pipe, one end of which extends into the positive pressure box 402, and the other end extends out of the positive pressure box 402, as Figure 3 shown. Preferably, a garbage guiding mechanism 7 is also arranged at the second exhaust port 5; the garbage entering the third pipeline 202 is guided by the garbage guiding mechanism 7 and then enters the positive pressure box 402; specifically, the garbage guiding mechanism 7 is a guiding wheel.

[0042] In another preferred embodiment, the second exhaust port 5 is a hole arranged on the pipe wall of the third pipeline 202, and the hole is arranged on the surface of the third pipeline 202 and above the positive pressure box 402; as Figure 4 shown. Figure 1 The size and shape of the second exhaust port 5 shown in are not used to limit the present invention. Further, a movable partition 4021 can be arranged in the positive pressure box 402 to divide the box body into upper and lower two-layer areas. The garbage enters the upper area in the positive pressure box 402 and sinks to the bottom of the box after passing through the movable baffle 4021, so that the garbage will not be discharged from the second exhaust port 5 under the impact of the positive pressure airflow.

[0043] Preferably, the fourth pipeline 204 can be either fixed on the garbage collection device or held by hand to position the fourth pipeline 204 to the place where cleaning is required.

[0044] When the fan 3 is running, the suction port of the fan 3 creates negative pressure in the second pipeline 203, the negative pressure box 401 and the first pipeline 201. Different directions of the negative pressure box 401 form negative pressure, and a spiral air flow is formed in the annular space around the positive pressure box 402. Dust, garbage, gravel, leaves, etc. enter the negative pressure box 401 from the negative pressure suction head 1, and the air flow is discharged through the first exhaust port 2031.

[0045] When the fan 3 is running, the air outlet of the fan 3 continuously blows air into the pipeline direct suction and pickup mechanism 6 to form a strong air flow. The air flow enters the positive pressure box 402 through the third pipeline 202, and positive pressure is formed in the third pipeline 202. Thus, negative pressure is generated in the fourth pipeline 204 to form a negative pressure suction head. The sucked garbage enters the positive pressure box 402 from the third pipeline 202, the garbage sinks to the bottom of the box, and the air is discharged through the second exhaust port 5. The fourth pipeline 204 and the third pipeline 202 connected to the pipeline direct suction and pickup mechanism 6 are straight pipelines, which are especially suitable for garbage with larger mass or volume on the road surface, such as soil, stones, branches, fallen fruits, fruit cores, etc. The positive pressure suction head and the negative pressure suction head cooperate to suck dust, effectively improving the cleaning effect. Preferably, a sliding door 9 can also be arranged in the third pipeline 202. When the sliding door 9 is closed, the connection between the third pipeline 202 and the fourth pipeline 204 is disconnected, and when the fan blows air, the fourth pipeline 204 forms positive pressure; when the sliding door 9 is opened, the third pipeline 202 and the fourth pipeline 204 are connected.

[0046] When the positive pressure box 402 or the negative pressure box 401 is full of garbage, open the bottom of the positive pressure box or the negative pressure box to empty the garbage and continue working.

[0047] The positive pressure suction head 1 and the negative pressure suction head 204 can work simultaneously or independently according to the actual situation.

[0048] In the existing road sweeper, the garbage collection box occupies a large space, and the remaining available space becomes smaller. In the garbage collection device of the present invention, the positive pressure box and the negative pressure box are sleeved, greatly saving space and having a high space utilization rate of the road sweeper. And only one fan is used to drive two dust collection systems, and the positive pressure suction head and the negative pressure suction head work simultaneously, significantly improving the efficiency of garbage cleaning. In addition, the positive pressure box and the negative pressure box are sleeved, and the air in the negative pressure box rotates around the positive pressure box to form a spiral air flow, and the spiral air flow significantly improves the suction force of the negative pressure suction head.

[0049] The garbage collection device of the present invention has a pipeline connected to the positive pressure box leading directly to the suction and pickup mechanism. The pipeline is completely straight from the negative pressure inlet to the positive pressure outlet. Such a device can be used to handle and transport impurities such as soil, stones, branches, fallen fruits, and fruit cores. The garbage collection device of the present invention uses the negative pressure suction head and the positive pressure suction head to cooperate for dust suction. A road sweeper equipped with the garbage collection device of the present invention can not only efficiently clean sundries such as fallen leaves, flying fluffs, and dust on the ground, but also suck in difficult-to-clean impurities such as stones and gravel. The application range is wider, the cleaning effect is remarkable, the use is more flexible, and it can achieve suction as it gets dirty, which is very convenient.

[0050] What is disclosed above is only the preferred embodiment of the present invention. The preferred embodiment does not elaborate on all details and does not limit the invention to the specific implementation manners described. Obviously, many modifications and variations can be made according to the content of this specification. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present invention, so that those skilled in the art can make good use of the present invention.
