Description

Technical Field

[0001] The utility model relates to the technical field of supporting facilities for sweeping vehicles, and in particular to a garbage collection device for an unmanned sweeping vehicle. Background Art

[0002] The emergence of driverless sweepers has provided a new way to clean up the urban environment, solving the problems of low efficiency and high labor intensity in traditional manual cleaning methods. In addition, driverless sweepers are being promoted and applied in more and more occasions because they do not require human intervention during operation. When collecting garbage and transporting it to the on-board garbage bin, the driverless sweeper mainly relies on the negative pressure in the transport channel to suck the garbage into the on-board garbage bin. Since the transport channel has a certain length, the garbage is easy to fall under its own gravity, and the overall weight of multiple garbage falls and becomes larger. The gathered garbage is easy to slide down along the inner wall of the transport channel and return to the ground at the rear side of the drum. Therefore, there are problems of incomplete garbage collection and blocked transport channels. Utility Model Content

DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0015] like Figure 1 and Figure 2 As shown, the garbage collection device for the unmanned sweeper is installed on the unmanned sweeper 1 and used in conjunction with the on-board garbage bin 2 provided on the unmanned sweeper 1, and is used to automatically collect the garbage on the ground into the on-board garbage bin 2 as the unmanned sweeper 1 moves, so as to clean the ground. Specifically, it includes a garbage collection pipe 3 obliquely arranged at the front side of the on-board garbage bin 2, the end of the garbage collection pipe 3 away from the on-board garbage bin 2 is vertically arranged to the ground and a garbage collection drum 4 is rotatably installed inside the garbage collection pipe 3, and the garbage collection drum 4 is connected to the power and control mechanism on the unmanned sweeper 1. When the garbage enters the garbage collection pipe 3, the garbage is thrown up under the rolling cooperation of the garbage collection drum 4.

[0016] A garbage collection port 5 is provided on the front wall of the garbage collection pipe 3, and a collection port baffle 6 of a soft structure is movably installed at the garbage collection port 5. Generally, the collection port baffle 6 is set as a rubber plate, which is easy to deform to avoid the entry of garbage, so that the garbage can successfully enter the garbage collection pipe 3. When external garbage enters the garbage collection pipe 3, the collection port baffle 6 automatically returns to close the garbage collection port 5, thereby reducing the amount of communication between the garbage collection pipe 3 and the outside, which helps to ensure the negative pressure state in the garbage collection pipe 3, so that the garbage can be successfully sucked into the vehicle-mounted garbage bin 2.

[0017] It also includes a garbage collection fan 7 for forming a negative pressure in the garbage collection pipe 3, the garbage collection fan 7 is electrically connected to the power supply and controller on the unmanned sweeper 1, the air inlet end of the garbage collection fan 7 is connected to the vehicle-mounted garbage bin 2, and the connection between the garbage collection fan 7 and the vehicle-mounted garbage bin 2 is provided with a filter screen 8, and the garbage collection fan 7 is connected to the top of the vehicle-mounted garbage bin 2, and the connection between the garbage collection pipe 3 and the vehicle-mounted garbage bin 2 is arranged below the filter screen 8. The garbage collection fan 7 is set as a high-pressure suction fan, which is used to suck out the air in the garbage collection pipe 3 and the vehicle-mounted garbage bin 2, so that a negative pressure is formed in the garbage collection pipe 3. After the garbage enters the vehicle-mounted garbage bin 2, the kinetic energy is reduced under the obstruction of the filter screen 8, and the garbage will fall freely into the vehicle-mounted garbage bin 2 by its own gravity, thereby realizing garbage collection and gas separation. The filter screen 8 can also prevent the garbage from being sucked into the garbage collection fan 7, and play a certain protective role on it.

[0018] A garbage suspension blowing device is connected to the garbage collection pipe 3, which is used to blow the garbage that sinks to the surface of the garbage collection pipe 3 into a suspended state, so that it can be smoothly transported to the vehicle-mounted garbage box 2 by negative pressure, and prevent the sunken garbage from sliding down along the inclined bottom wall of the garbage collection pipe 3 and returning to the ground, thereby improving the garbage collection rate and ensuring the ground cleaning effect. The blowing volume of the garbage suspension blowing device and the suction volume of the garbage collection fan 7 need to be reasonably configured so that the two can cooperate smoothly to ensure that sufficient negative pressure adsorption force can be formed on the garbage.

[0019] Specifically, the garbage suspension blowing device includes a blowing cloth air cover plate 9 fixedly arranged on the outer side of the inclined bottom wall of the garbage collection pipe 3, and a blowing cloth air chamber 10 is formed between the blowing cloth air cover plate 9 and the garbage collection pipe 3, so that the inclined bottom wall of the garbage collection pipe 3 also serves as a cavity wall of the blowing cloth air chamber 10, so as to reduce the vehicle load and reduce the energy consumption of the unmanned sweeper 1 during operation. The garbage collection pipe 3 is provided with a blowing hole 11 connected to the blowing cloth air chamber 10, and also includes a high-pressure gas source device, which is connected to the blowing cloth air chamber 10 through the blowing cloth air cover plate 9. The blowing cloth air chamber 10 is used for the reasonable distribution of high-pressure gas to ensure that each of the blowing holes 11 can obtain sufficient high-pressure gas for blowing. The high-pressure gas source device is used to provide a high-pressure gas source to the blowing cloth air chamber 10. The spray hole 11 is configured as a trumpet hole, and the wide end of the spray hole 11 faces the inner cavity of the garbage collecting pipe 3 to ensure the spray area.

[0020] The high-pressure gas source device includes a high-pressure gas storage tank 12 connected to the blowing cloth air cover plate 9, and the high-pressure gas storage tank 12 is connected to an air supplement booster pump 13. A pulse blowing valve 14 is provided at the connection between the high-pressure gas storage tank 12 and the blowing cloth air cover plate 9. The pulse blowing valve 14 and the air supplement booster pump 13 are respectively electrically connected to the power supply and controller on the unmanned sweeper 1. The pulse blowing valve 14 can be controlled and set by the controller, such as spraying the garbage collection pipe 3 intermittently or continuously, so that the garbage can be smoothly sucked into the vehicle-mounted garbage bin 2.

[0021] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
