Description

Technical Field

[0001] This utility model relates to the field of garbage sweepers, specifically to a garbage container with dual airflow channels. Background Technology

[0002] Garbage sweepers mainly utilize the airflow generated by a high-speed rotating centrifugal fan to pick up various materials distributed on the road surface or construction work surface. The rotation of the fan impeller will generate negative pressure airflow in the channel between the sweeper's suction cup and the fan inlet. The two main parameters of the negative pressure airflow are negative pressure and air volume, which determine the effectiveness of the suction.

[0003] For a given blower, a negative pressure channel is essential and must be sealed to achieve the maximum possible negative pressure and airflow. Simultaneously, to facilitate both garbage collection and separation, the garbage bin itself is part of the negative pressure channel. Generally, the centrifugal blower of this type of sweeper exhausts air into the air, sometimes even generating secondary dust or blowing pollution. The negative pressure airflow of existing garbage sweepers has extremely short contact time with garbage particles on the road surface, making reliable collection impossible. Therefore, the cleaning rate is very low under high-speed operation. Utility Model Content

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-3 The garbage bin shown includes a fan chamber 1 and a garbage bin body 2. The fan chamber 1 is fixed to the front end of the garbage bin body 2. A positive pressure airflow horizontal channel 4 is fixed inside the top of the fan chamber 1. A positive pressure airflow inlet pipe 3 is connected to one end of the positive pressure airflow horizontal channel 4 located in the fan chamber 1. The end of the positive pressure airflow horizontal channel 4 extends to the rear end of the garbage bin body 2, and two positive pressure airflow jet pipes 5 are connected to the end of the positive pressure airflow horizontal channel 4. The two positive pressure airflow jet pipes 5 are vertically downward and penetrate to the bottom of the garbage bin body 2.

[0019] The blower compartment 1 is equipped with a negative pressure air outlet pipe 6. One end of the negative pressure air outlet pipe 6 extends into the interior of the garbage bin body 2, and a filter screen 8 is installed at the end of the negative pressure air outlet pipe 6 located inside the garbage bin body 2.

[0020] A vertical suction pipe 7 is fixed inside the trash can body 2, and the bottom end of the vertical suction pipe 7 extends to the bottom of the trash can body 2.

[0021] Furthermore, a baffle 9 is fixed inside the trash can body 2. The baffle 9 is located between the filter screen 8 and the vertical suction pipe 7, and the lowest surface of the baffle 9 is lower than the highest surface of the vertical suction pipe 7.

[0022] This utility model includes a blower (not shown in the figure, it is part of the garbage sweeper's equipment) in the blower compartment. The blower's outlet is connected to the positive pressure airflow inlet pipe 3, and the blower's inlet is connected to the negative pressure airflow outlet pipe 6. During the blower's operation, positive pressure air enters the suction cup through the positive pressure airflow inlet pipe 3, the positive pressure airflow horizontal channel 4, and the positive pressure airflow blow pipe 5 (the suction cup is also not shown in the figure, it belongs to another invention design, and the suction cup is installed at the bottom of the garbage bin body 2). Then, the airflow flows from inside the suction cup to the bottom of the vertical suction pipe 7. During the flow of the airflow through the suction cup, dust particles are sucked into the interior of the garbage bin body 2 through the vertical suction pipe 7. Then, under the action of the filter screen 8, they are isolated in the garbage bin body 2.

[0023] In short, the positive pressure airflow inlet pipe 3, the positive pressure airflow horizontal channel 4, and the positive pressure airflow blow pipe 5 constitute the positive pressure airflow channel; the negative pressure airflow outlet pipe 6, the trash can body 2, the filter screen 8, and the vertical suction pipe 7 form the negative pressure airflow channel; thus, the positive pressure airflow channel and the negative pressure airflow channel are all integrated in the trash can, providing a sealed channel for the positive pressure airflow and the negative pressure airflow to be separated from each other.

[0024] The positive pressure airflow inlet pipe 3 and the vertical suction pipe 7 are both connected to the suction cup via flexible hoses to form a flexible connection between the trash can and the integrated suction cup and ensure a seal during the tipping of the trash can.

[0025] The dual-airflow channel garbage bin provided by this utility model integrates a negative pressure airflow channel and a positive pressure airflow channel, providing a garbage bin with a simple structure and complete functions for the development of sweeper trucks that use the principle of airflow circulation to enhance the rapid suction effect, and solving a series of problems such as the arrangement, fixing and connection of the positive pressure airflow channel.
