Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] Please refer to Figs. 1-3 The utility model discloses a kind of arbor shrub dust collection devices, the device includes shell 1, the upper portion of the shell 1 is equipped with assembly cavity 2, and ultrasonic generator 3 is installed in assembly cavity 2, the top of assembly cavity 2 is embedded with cleaning tank 4, and the lower portion of cleaning tank 4 is installed with ultrasonic transducer 5, the ultrasonic transducer 5 is electrically connected with ultrasonic generator 3, the lower portion of the cleaning tank 4 is equipped with sink 6, and sealing rubber ring 7 is clamped in sink 6, HEPA filter cloth 8 is equipped in sealing rubber ring 7, the bottom of sink 6 is equipped with drain 9, and electromagnetic valve 10 is installed on drain 9, the lower portion of the shell 1 is equipped with drying cavity 11, and screen plate 12 is equipped in drying cavity 11.Worker can put the collected leaf sample into the cleaning tank 4 equipped with pure water, utilize the high frequency vibration of ultrasonic to act on leaf sample in water, to wash leaf, peel off dust, dust is deposited on HEPA filter cloth 8 to carry out solid-liquid separation, then after HEPA filter cloth 8 containing dust is put into drying cavity 11 and dried, it is weighed.Optimally, the lower portion of screen plate 12 is installed with electric heating rod 13, the front side of drying cavity 11 is equipped with box door 14 by hinge.

[0021] Specifically, the front side of shell 1 is embedded with controller 15, ultrasonic generator 3, electromagnetic valve 10 and electric heating rod 13 are electrically connected with controller 15 respectively.In the embodiment, controller 15 is a kind of equipment that is uniformly managed and controlled by software program to various hardware, can control and manage multiple devices and realize collaborative work.

[0022] Specifically, the top of assembly cavity 2 is equipped with mouth 16, and cleaning tank 4 is embedded in assembly cavity 2 through mouth 16.In the embodiment, mouth 16 is assembly structure, for the installation and fixation of cleaning tank 4.

[0023] Specifically, the ultrasonic transducer 5 is uniformly distributed in the lower part of the cleaning tank 4, and the sink 6 is located below the ultrasonic transducer 5. In this embodiment, the ultrasonic generator 3 generates high-frequency electric energy higher than 20 kHz, which is converted into mechanical vibration of the same frequency by the ultrasonic transducer 5, and then transmitted into pure water. In the pure water, the ultrasonic waves form countless micro-bubbles, which are formed in the negative pressure area and rapidly broken in the positive pressure area, generating a transient high pressure exceeding 1000 atmospheres. This phenomenon is called cavitation effect. The shock wave generated when the bubbles break will continuously bombard the surface of the plant leaves, causing the dust on the leaves to fall off quickly.

[0024] Specifically, the bottom of the drain 9 is connected with a drain pipe 17, and one end of the drain pipe 17 extends out of the casing 1. In this embodiment, after the cleaning of the leaf samples is completed, the electromagnetic valve 10 is controlled to open, so that the water is discharged outward and the solid-liquid separation is performed through the HEPA filter cloth 8.

[0025] Specifically, the sandwich layer 18 is arranged between the drying cavity 11 and the assembly cavity 2, and the two sides of the sandwich layer 18 are open structures. In this embodiment, the sandwich layer 18 mainly plays a heat insulation role, which can avoid the heat in the drying cavity 11 from being conducted into the assembly cavity 2.

[0026] In use, the staff needs to sample the leaves of the arbor and shrub in the urban green belt, and the sampling position is the leaves on the upper branches in the middle part of the four directions of southeast, southwest, northwest and northeast of the tree crown. The leaves are carefully sealed in a plastic bag and taken back to the laboratory for processing the amount of dust on the leaf surface. The specific method is as follows: the arbor and shrub leaf samples collected in the urban green belt are placed in the cleaning tank 4 filled with pure water, the high-frequency vibration of the ultrasonic waves is used on the leaf samples in the water, so as to quickly strip the dust on the leaf surface. When the dust enters the water, the electromagnetic valve 10 is controlled to open, so that the water is discharged outward, the dust is deposited on the HEPA filter cloth 8 for solid-liquid separation. Then, the HEPA filter cloth 8 containing the dust is placed in the drying cavity 11 for drying, and then the mass of the dust and the filter cloth is weighed. Then, the weight of the filter cloth itself is subtracted, so as to obtain the dust amount data of the plant leaves.

[0027] The calculation method of the dust amount per unit leaf area is as follows: the weight difference (W2-W1) of the weighed HEPA filter cloth is taken as the weight of the sample adsorbed particulate matter, that is, the total weight of the dust on the leaves. Finally, the dust amount per unit leaf area Q (mg / cm 2 ) is calculated, as shown in formula (1).

[0028] Q = (W1-W2) / A …………………… (1)

[0029] In formula (1), W1 is the mass of the dried HEPA filter cloth, W2 is the mass after deposition of the dust-retaining turbid liquid, drying to constant weight and cooling and weighing, and A is the leaf area of the collected leaf sample of the arbor and shrub.

[0030] In summary, the device saves time and effort in the whole dust-retaining collection and determination operation process, can be used for comparison of the dust-retaining amounts of different arbor and shrub plant leaves, and thus provides a reference for selection and configuration of greening tree species in cities.

[0031] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
