[0035] Dust collection pipeline 2 is set in the inside lower end of cutting bin 1 and is communicated with cutting area 11, and its lower end extends to the bottom of cutting bin 1;

[0036] Filtering assembly 3 is set in the lower end of dust collection pipeline 2 to receive dust and dirt falling from dust collection pipeline 2, and filtering assembly 3 includes treatment pipeline 31 and treatment pool 32, the upper end of treatment pipeline 2 is connected to the lower end of dust collection pipeline 2, and the lower end of treatment pipeline 31 is placed in treatment pool 32;

[0037] Among them, high-pressure sprayer 33 is provided on treatment pipeline 31, and the spraying end of high-pressure sprayer 33 is arranged in treatment pipeline 31 and sprays towards the lower end of treatment pipeline 33, to form negative pressure at the lower end of treatment pipeline 31, and high-pressure sprayer 33 and positive pressure fan 12 jointly form downward directional airflow, to direct dust and dirt into treatment pool 32.

[0038] The embodiment blows wind to cutting area 11 by positive pressure fan 12, while high-pressure sprayer 33 sprays into treatment pipeline 31, to form negative pressure at the lower end of treatment pipeline 31, thereby forming downward directional airflow, and then blowing dust and dirt generated in cutting area 11 downward into dust collection pipeline 2, and conveying dust and dirt to treatment pipeline 31 by dust collection pipeline 2, and flushing dust and dirt into treatment pool 32 by high-pressure sprayer 33.

[0039] The embodiment forms positive pressure by blowing air into the cutting area 11 by the positive pressure fan 12, and forms negative pressure by spraying into the processing pipeline 31 by the high-pressure sprayer 33, thereby forming a downward directional airflow, and the dust generated in the cutting area 11 can enter the dust collection pipeline 2 along the directional airflow, be transported to the processing pipeline 31 through the dust collection pipeline 2, and be flushed into the processing pool 32 by the high-pressure sprayer 33, thereby achieving the effect of stably capturing cutting dust.

[0040] In order to enable the high-pressure sprayer 33 to spray towards the lower end of the processing pipeline 31 to form a negative pressure environment, the following preferred embodiments are proposed.

[0041] As shown in Figure 3 , the processing pipeline 31 is a Y-shaped pipe, and the upper end of the processing pipeline 31 has a feeding branch 311 and a spraying branch 312, the feeding branch 311 is connected to the lower end of the dust collection pipeline 2, and the high-pressure sprayer 33 is arranged in the spraying branch 312.

[0042] Specifically, the high-pressure sprayer 33 sprays high-pressure water mist towards the lower end of the processing pipeline 31, which can flush the gas in the processing pipeline 31 into the processing pool 32, thereby forming a negative pressure environment in the feeding branch 311, and further cooperating with the positive pressure fan 12 to form a downward directional airflow.

[0043] During the cutting process, the high-pressure sprayer 33 can continuously spray into the processing pool 32, in order to prevent the water in the processing pool 32 from overflowing due to long-time spraying, the following preferred embodiments are proposed.

[0044] As shown in Figure 4 , the lower end of the processing pool 32 is provided with a drain pipe 321, and the drain pipe 321 is provided with a hydraulic valve 322, which can automatically open the drain when the water pressure exceeds a threshold value, or close to stop the drain when the water pressure is lower than the threshold value.

[0045] Among them, after the cutting is completed, the hydraulic valve 322 can be manually controlled to open to drain the water in the processing pool 32.

[0046] Specifically, when the water level in the processing pool 32 rises, causing the water pressure to be greater than the threshold value of the hydraulic valve 322, the hydraulic valve 322 can automatically open the drain, and when the water level in the processing pool 32 drops, causing the water pressure to be less than the threshold value of the hydraulic valve 322, the hydraulic valve 322 can automatically close to stop the drain.

[0047] Among them, after the cutting is completed, the hydraulic valve 322 can be manually controlled to open to drain the water in the processing pool 32.

[0048] The wood chips in the dust can be used as a biomass material and have multiple uses. The fine dust in the dust is useless. In order to separate the wood chips from the fine dust and facilitate the recycling of the wood chips, the following preferred embodiments are proposed.

[0049] As shown in Figure 1 and 4 , a filter cartridge 34 is arranged in the treatment tank 32, the lower end of the treatment pipeline 31 is inserted into the filter cartridge 34, and the filter cartridge 34 is partially submerged in the water in the treatment tank 32;

[0050] After the dust generated in the cutting area 11 is carried into the treatment pipeline 31 by the directional airflow along the dust collection pipeline 2, the high-pressure sprayer 33 flushes the dust and falls into the filter cartridge 34, so that the part of the dust soluble in water passes through the filter cartridge 34 and can be discharged from the treatment tank 32 with the water, the wood chips cannot pass through the filter cartridge 34 and float on the water surface in the filter cartridge 34, and the part of the dust insoluble in water is deposited at the bottom of the filter cartridge 34, so as to automatically separate the dust.

[0051] Specifically, after the dust is sprayed, part of the soluble dust can be discharged into the treatment tank 32 with the water, the wood chips cannot pass through the filter cartridge 34 and float on the water surface in the filter cartridge 34, and part of the insoluble dust is deposited at the bottom of the filter cartridge 34, so as to automatically separate the dust.

[0052] When the cutting is finished and the water is drained, the soluble dust can be discharged from the treatment tank 32 with the water, and the dust deposited at the bottom of the filter cartridge 34 can be difficult to be discharged with the water, so that when the wood chips fall to the bottom of the filter cartridge 34, they are mixed with part of the residual dust; in addition, after the drainage is completed, part of the liquid droplets containing dust can be attached to the wood chips and be difficult to be discharged. Therefore, in order to fully remove the dust, the following preferred embodiments are proposed.

[0053] As shown in Figure 4 , the bottom of the treatment tank 32 is provided with a centrifugal motor 323, the shaft of the centrifugal motor 323 is installed at the center of the bottom of the filter cartridge 34, and the centrifugal motor 323 is used to rotate the filter cartridge 34.

[0054] Specifically, the centrifugal motor 323 can drive the filter cartridge 34 to rotate and centrifuge, so as to throw out the dust deposited at the bottom of the filter cartridge 34 and the liquid droplets attached to the wood chips to the treatment tank 32 for discharge.

[0055] In order to ensure that the dust falls into the dust collection pipeline 2 when it falls along with the directional airflow, and falls along the dust collection pipeline 2 into the treatment pipeline, the following preferred embodiments are proposed.

[0056] As shown in Figure 2As shown, the dust collection pipeline 2 comprises two dust collection cylinders 21 arranged side by side, and a slanted guide pipeline 22 is connected below the two dust collection cylinders 21, and the slanted lower end of the guide pipeline 22 is connected with the upper end of the feeding branch 311;

[0057] The dust collection cylinder 21 is tapered from top to bottom, and the upper end edges of the two dust collection cylinders 21 are fixed on the inner wall of the cutting bin 1, and the upper edges of the dust collection cylinders 21 are in close contact with the inner wall of the cutting bin 1.

[0058] The upper end of the dust collection cylinder 21 is used to fix the plate cutting support in the cutting bin 1 to form the cutting area 11.

[0059] Specifically, the edges of the two dust collection cylinders 21 are fixed on the inner wall of the cutting bin 1, which can ensure that the dust falls into the dust collection cylinder 21 along the directional airflow and falls into the treatment pipeline 31 along the guide pipeline 22.

[0060] In the working process of the embodiment, the positive pressure fan 12 blows air downward to generate positive pressure, and the high-pressure sprayer 33 sprays to generate negative pressure, so as to form a directional airflow from top to bottom in the cutting bin 1. When cutting, the dust is blown downward into the dust collection cylinder 21 by the directional airflow, and then the dust is guided and transported to the treatment pipeline 31 through the guide pipeline 22. The dust enters the feeding branch 311, enters the filter cylinder 34 through spraying, part of the dust dissolved in water passes through the filter cylinder 34 and can be discharged with water from the treatment tank 32, and the wood chips cannot pass through the filter cylinder 34 and float on the water surface in the filter cylinder 34. Part of the dust that is not soluble in water is precipitated at the bottom of the filter cylinder 34. After cutting is completed, the hydraulic valve 322 is opened to drain water, and the centrifugal motor 323 is started to drive the filter cylinder 34 to centrifuge, so that the dust in the filter cylinder 34 is thrown out with water, and the wood chips remain in the filter cylinder 34. After the water is drained, the wood chips can be flushed by spraying.

[0061] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the present application.
