DETAILED DESCRIPTION

[0013] The present invention is further described in detail below through specific implementation methods:

[0014] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes an electrostatic sand planting device, including sandpaper 2 provided with electrostatic adsorption by an electrostatic electrode plate 1, a sand guide cylinder 3 and an air flow generator 5, the sand guide cylinder 3 is arranged in a vertical direction and has air outlet holes 6 and sand outlet holes 7 arranged opposite to each other on its side wall, and one side of the sandpaper 2 is connected to the sand outlet hole 7 through a sealing cover 8; the air flow generator 5 is located on one side of the sand guide cylinder 3 and is connected to the air outlet hole 6.

[0015] In this electrostatic sand planting device, sand particles flow downward in the sand guide tube 3 under the action of gravity, and the airflow generator 5 generates an airflow to enter the sand guide tube 3 from the air outlet 6, and blows the sand particles flowing downward in the sand guide tube 3 into the sealing cover 8 from the sand outlet hole 7 until the sand particles adhere to the sandpaper 2 to carry out the sand planting work. The sealing cover 8 prevents the sand particles from splashing everywhere, thereby optimizing the working environment, and collects the sand particles that do not adhere to the sandpaper 2 to reduce waste.

[0016] In this embodiment, the airflow generator 5 may be a blower, but is not limited thereto.

[0017] In order to make the electrostatic sand planting device more reasonable during use, the electrostatic sand planting device will be further optimized below.

[0018] like Figure 1 and Figure 2 As shown, according to another embodiment of the present utility model, an electrostatic sand planting device is provided, wherein a sand return hole 9 located below the sand outlet hole 7 is opened on the side wall of the sand guide cylinder 3, and a sand return channel connected to the sand return hole 9 is formed on the inner bottom side of the sealing cover 8.

[0019] Among them, the sand grains that are not adhered to the sandpaper 2 fall into the sand return channel in the sealing cover 8, and then enter the sand return hole 9 and return to the sand guide cylinder 3, so as to prevent the sand grains from accumulating in the sealing cover 8 and affecting the sand planting work.

[0020] The electrostatic sand planting device further includes a collecting trough 10 , which is located below the sand guide cylinder 3 and the bottom end of the sand guide cylinder 3 is connected to the collecting trough 10 .

[0021] The small amount of sand particles not blown into the sealing cover 8 directly pass through the sand guiding cylinder 3 into the collecting groove 10 for collection. The sand particles not adhered to the sand paper 2 fall into the sand returning channel in the sealing cover 8, are guided into the collecting groove 10 through the sand guiding cylinder 3, and can be reused to reduce waste.

[0022] In order to enable the sand particles falling into the sand returning channel to quickly return to the sand guiding cylinder 3 from the sand returning hole 9, the bottom wall in the sealing cover 8 is arranged to be inclined and the low end thereof is connected with the sand returning hole 9. Then the sand particles falling on the bottom wall in the sealing cover 8 quickly slide from the sand returning hole 9 to the sand guiding cylinder 3 under the action of their own gravity, and then enter the collecting groove 10 for collection.

[0023] As shown in Figure 1 and Figure 2 According to another embodiment of the utility model, the electrostatic sanding device further comprises a mounting cylinder 11 arranged in the vertical direction, the sand paper 2 is arranged in the mounting cylinder 11 and the over sand hole 12 aligned with the sand outlet hole 7 is formed in the side wall of the mounting cylinder 11, and the sand paper 2 covers the over sand hole 12 by being attached to the inner wall of the mounting cylinder 11.

[0024] In the embodiment, the electrostatic plate 1 is also arranged in the mounting cylinder 11, the mounting cylinder 11 provides mounting space for the electrostatic plate 1 and the sand paper 2, and the sand paper 2 covers the over sand hole 12 by being attached to the inner wall of the mounting cylinder 11. Then the sand particles blown into the sealing cover 8 adhere to one side of the sand paper 2 through the over sand hole 12, and the sand particles cannot enter the mounting cylinder 11. The sand particles not adhered to the sand paper 2 fall on the bottom wall in the sealing cover 8 and then slide into the sand guiding cylinder 3, and then enter the collecting groove 10 for recycling.

[0025] As shown in Figure 1 According to another embodiment of the utility model, the electrostatic sanding device further comprises a sand storage tank 13, the sand outlet of the bottom of the sand storage tank 13 is communicated with the top end of the sand guiding cylinder 3, and the adjusting valve 14 is arranged on the top side of the sand guiding cylinder 3.

[0026] The sand particles are stored in the sand storage tank 13, the adjusting valve 14 is opened to guide the sand particles into the sand guiding cylinder 3, and the airflow generator 5 is started. The airflow generator 5 generates airflow to enter the sand guiding cylinder 3 from the air outlet hole 6, blows the sand particles flowing downward in the sand guiding cylinder 3 into the sealing cover 8 from the sand outlet hole 7, and then the sand particles adhere to one side of the sand paper 2 through the over sand hole 12. The sand particles not adhered to the sand paper 2 fall on the bottom wall in the sealing cover 8 and then slide into the sand guiding cylinder 3. At the same time, the small amount of sand particles not blown into the sealing cover 8 during the falling process in the sand guiding cylinder 3 continue to slide downward in the sand guiding cylinder 3, and then the sand particles all fall into the collecting groove 10 for collection.

[0027] Since the sand storage tank 13 is installed at a high position, the sand collected in the collecting groove 10 can be returned to the sand storage tank 13 for continuous use by using a feeding mechanism such as an auger, and when the sand is added to the sand storage tank 13, the sand can also be added to the collecting groove 10 and then enter the sand storage tank 13 through the feeding mechanism.

[0028] As shown in Figure 1 and Figure 2 According to another embodiment of the utility model, the air outlet of the airflow generator 5 is communicated with the air outlet hole 6 through the air distribution cover 15, the air distribution cover 15 includes the air guide part 151, the air distribution part 152 and the flow distribution plate 153, the air guide part 151 has a tapered air guide cavity, and the small end of the air guide cavity is connected with the air outlet of the airflow generator 5; the air distribution part 152 has a cylindrical air distribution cavity, one end of the air distribution cavity is communicated with the large end of the air guide cavity, and the other end is communicated with the air outlet hole 6, and the air distribution net plate 154 is arranged in both ends of the air distribution cavity; the flow distribution plate 153 is scattered in the air guide cavity, and each flow distribution plate 153 extends from the small end of the air guide cavity to the large end of the air guide cavity and is connected with the corresponding air distribution net plate 154.

[0029] In the embodiment, when the airflow generator 5 is started, the airflow generated by the airflow generator 5 enters the air guide cavity, and the airflow is uniformly distributed from the large end of the air guide cavity to the air distribution cavity through the arrangement of the multiple flow distribution plates 153, and then the airflow is uniformly distributed again, and then the airflow passes through the other air distribution net plate 154 and then uniformly passes through the air outlet hole 6, so that the sand particles can be uniformly distributed to one side of the sandpaper 2 to plant sand. Although the two air distribution net plates 154 cause a certain resistance to the flow of the airflow, the airflow distribution is more uniform, and the distribution of the sand particles on the sandpaper 2 is also more uniform.

[0030] It should be noted that the airflow generated by the airflow generator 5 has a large flow force, and the flow distance is relatively short, and the sand particles basically move in a straight line from the sand outlet hole 7 to adhere to the sandpaper 2.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, and they should be covered in the scope of the claims of the utility model.
