Description

Automatic leaf cleaning machine and working method based on humid environment

technical field

The present invention relates to a cleaning machine mechanism, more specifically, it is an automatic leaf cleaning machine based on a humid environment, and also relates to the working method of this automatic leaf cleaning machine.

Background technique

Known at present, as one of the environmental sanitation equipment of city road, fallen leaf sweeper is a kind of indispensable novel high-efficiency sweeping equipment of cleaning road surface. The current fallen leaf cleaning machines are divided into three types: pure suction type, pure sweeping type, and suction sweeping type, all of which combine the action of air flow to clean fallen leaves, but in a humid environment, fallen leaves are attached to the ground under the tension of the liquid , Ordinary leaf sweepers cannot complete the complete sweeping task. Therefore, a key problem that needs to be overcome in the development process of the leaf sweeper is the problem in a humid environment. The traditional leaf sweeper is mainly designed for urban roads, parks, residential areas, and school main roads. Most of them use The principle of vacuum cleaning is used to absorb fallen leaves, but in a humid environment, there is a large "attraction" between fallen leaves and the ground, which makes it difficult to absorb. Patent "A Processor for Plant Fallen Leaves", application number: 201020637960.6, involves wet fallen leaves, but this patent is aimed at classifying the difference in weight between wet fallen leaves and dry fallen leaves, recycling and reusing plant fallen leaves, and does not solve the problem of wet fallen leaves The problem of absorption from ground cleaning, therefore, the problem of leaf sweepers in wet environments needs to be solved urgently.

Contents of the invention

The first object of the present invention is to overcome the disadvantages of the above-mentioned background technology, and provide an automatic cleaning machine for fallen leaves based on a humid environment. The device has a compact structure and effectively solves the problem that fallen leaves are not easy to absorb in a humid environment.

The second object of the present invention is to provide the working method of this automatic leaf cleaning machine.

In order to realize the first object of the present invention, the technical scheme of the present invention is such: the automatic cleaning machine of fallen leaves based on the humid environment, including the push handle frame, the universal wheel installed under the thick bottom plate, the support plate above and the leaf collecting box It also includes a pneumatic transmission system, an exhaust blowing system, and a cleaning operation system; the pneumatic transmission system includes: the suction leaf pipeline is connected to the leaf collecting box, and the leaf collecting box is connected to the fan cover through the positioning shell. A fan is fixedly installed in the fan cover, and a protective frame is installed between the fan and the leaf collecting box; the exhaust blowing system includes: a blowing duct is connected above the exhaust port of the fan, and the blowing duct passes through a PLC, PLC can be programmed logic controller to control the reversing valve to send pulsed air in all directions; the cleaning operation system includes: the motor is connected to the pulley through a common belt, and the pulley transmits power to the disc brush through the gear box and roller brush.

In the above technical solution, the reversing valve of the exhaust blowing system generates instructions to the pulse signal generator through the PLC, and the signal of the pulse signal generator is then input to the reversing valve.

In the above technical solution, the belt pulley of the cleaning system transmits power to the disc brush through a bevel gear.

In the above technical solution, the disc brushes are arranged symmetrically at the front end of the suction vane pipeline, the number of disc brushes is two, and the roller brushes are arranged between the disc brushes and located on the suction vane. The front end of the pipeline.

In the above technical solution, the fan is installed on the support plate, and the fan is a centrifugal fan.

In order to realize the second purpose of the present invention, the technical solution of the present invention is: the working mode of the automatic cleaning machine for fallen leaves based on wet environment, it comprises the following steps:

First, turn on the power supply, start the centrifugal fan and the motor at the same time, the centrifugal fan evacuates the air in the leaf collecting box, and forms a negative pressure difference between the inside of the leaf collecting box and the outside of the leaf collecting box. The air outside the leaf box enters the box under the action of atmospheric pressure, and in the process of entering the suction leaf pipeline, it rubs against the fallen leaves, which reduces the adsorption force between the ground and the fallen leaves to a certain extent. Wheel drive, the belt wheel drives the bevel gear to rotate, and the bevel gear drives the disc brush and roller brush at the front end of the suction nozzle to rotate, and cooperates with cleaning fallen leaves to enter the suction leaf pipeline;

Then, the wind extracted by the centrifugal blower utilizes the PLC program to control the opening and closing of the valve, which is opened once every 1-2s, so that the extracted gas is discharged intermittently, and the intermittent wind pressure is added to the wet fallen leaves, so that the fallen leaves are affected. The force has been in an unstable state, which has a stronger effect on weakening the adsorption force between the fallen leaves and the ground, and can more effectively cooperate with the suction nozzle to absorb the fallen leaves;

Finally, under the comprehensive action of the disc brushes, rolling brushes, leaf suction pipes and blowing pipes, the wet fallen leaves are successfully sucked into the leaf collecting box from the leaf suction pipes.

The beneficial effects of the present invention are:

One is to effectively solve the problem of cleaning fallen leaves in a humid environment by adopting a pneumatic transmission system, a cleaning operation system, and an exhaust blowing system.

The second is the integrated design of the pneumatic transmission system, cleaning operation system, and exhaust blowing system, with a compact structure.

The third is to use the exhaust of the fan to generate pulsating blowing. The fan not only sucks and exhausts the air for the leaf collecting box but also pulsates and blows the wet fallen leaves, which improves work efficiency and saves energy.

The fourth is to push the hand frame by hand, so that the machine can walk freely, which is easy to operate and easy to use, which reduces the burden on the operator.
