[0003] In wood processing, common dust removal equipment mainly includes mesh filters and bag filters, among which, mesh filters use fabric bags as filter elements, and introduce dust-containing gas into the bag through a negative pressure pipe, and the dust is retained on the bag. The purified air is discharged through the bag. A dust hood is provided at the input end of the negative pressure pipe. The dust hood is generally installed on the top of the processing area so that the debris generated during processing can be quickly sucked into the filter through the dust hood. In order to prevent large particles of debris and debris from entering the filter together, a filter is often provided at the opening of the dust hood. The filter can perform preliminary filtration on the dust-containing airflow, but because the dust hood mostly works in dusty places, the problem of dust accumulation on the filter will also be very serious, affecting the passage of airflow. The staff needs to regularly clean the filter with a brush. The brush cleaning method is time-consuming and labor-intensive, and the maintenance process is long, which affects the processing operation. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] according to Figure 1 , 2 As shown in Figures 3 and 4, a dust removal device for a wood processing site is proposed in this embodiment, including an adjusting plate 1, two dust hoods 3 are arranged on one side of the adjusting plate 1, and the two dust hoods 3 are arranged up and down. A transmission mechanism for adjusting the distance between the two dust hoods 3 is provided on the adjusting plate 1; one of the two dust hoods 3 is placed above the processing table to remove dust from the area above the processing table, and the other is placed below the processing table to remove dust from the area below the processing table. The dust removal range is more comprehensive, and the adjustable connection method is convenient for the staff to adjust the installation position of the dust hood 3 according to actual needs, and the flexibility is high.

[0022] A dust collecting duct 5 is provided on the back of the dust hood 3, and the dust collecting duct 5 is connected with the dust hood 3. A filter plate frame 4 is provided inside the dust hood 3, and spring rod structures are provided on both sides of the filter plate frame 4. The filter plate frame 4 is floatingly connected with the dust hood 3 through the spring rod structure; the dust hood 3 is connected with an external negative pressure dust collecting device through the dust collecting duct 5, and a negative pressure is formed inside the dust hood 3. The dust-laden airflow is drawn into the dust hood 3. When passing through the filter plate frame 4, the filter plate frame 4 will block large particles of debris in the air to prevent large particles of debris from blocking the dust collecting duct 5, and perform preliminary filtration on the airflow. Among them, the negative pressure dust collecting device can be a cartridge dust collector or a bag dust collector, etc., which will not be explained in detail here.

[0023] A striker structure and a reciprocating push assembly are provided inside the dust hood 3. The striker structure is placed on one side of the filter plate frame 4 close to the adjustment plate 1, and the reciprocating push assembly is placed on the other side of the filter plate frame 4 to push the filter plate frame 4 to collide with the striker structure. The filter plate frame 4 is assembled in the dust hood 3 through a spring rod structure, and the spring rod structure supports the filter plate frame 4 to swing left and right in the dust hood 3.

[0024] When the filter plate frame 4 is full of dust, the reciprocating pushing assembly will push the filter plate frame 4 to shake in the dust hood 3, causing the filter plate frame 4 to collide with the striker structure. While the filter plate frame 4 is shaking, the striker structure strikes the filter plate frame 4 to ensure that the dust attached to the filter plate frame 4 falls off quickly, making cleaning and maintenance efficient.

[0025] Specifically, the spring rod structure includes a plurality of limit rods 12, each of which is fixedly connected to both sides of the filter plate frame 4. The limit rod 12 is away from the filter plate frame 4 and passes through the dust cover 3 and is slidably connected to the dust cover 3. A spring 13 is sleeved on the outer side of the limit rod 12, and the two ends of the spring 13 are respectively fixedly connected to the filter plate frame 4 and the inner side wall of the dust cover 3. The springs 13 on both sides of the filter plate frame 4 provide floating support for the filter plate frame 4 and suspend the filter plate frame 4 in the middle area of ​​the dust cover 3. When the filter plate frame 4 is pushed to the left, the limit rod 12 guides the horizontal movement of the filter plate frame 4, and the spring 13 on one side of the filter plate frame 4 is compressed, and the spring 13 on the other side of the filter plate frame 4 is expanded. When the thrust applied to the filter plate frame 4 disappears, the filter plate frame 4 will return to its original position under the action of the spring 13.

[0026] Regarding the striker structure: the striker structure includes a metal ring 18 and a striker 19. The metal ring 18 is fixedly connected to the side of the filter plate frame 4 close to the adjustment plate 1, and the striker 19 is placed on the side of the metal ring 18 away from the filter plate frame 4. The striker 19 is fixedly connected to the inner wall of the dust cover 3, and a gap is left between the striker 19 and the metal ring 18. When the filter plate frame 4 approaches the striker 19, the metal ring 18 will collide with the striker 19. After the metal ring 18 and the striker 19 collide, the force will be transmitted to the filter plate frame 4, causing the filter plate frame 4 to vibrate at a high frequency, thereby accelerating the shedding of dust on the filter plate frame 4.

[0027] The reciprocating push assembly pushes the filter plate frame 4 from the side of the filter plate frame 4 away from the striker structure, and the reciprocating push assembly includes a second motor 14, a convex disc 15 and a baffle 16, the baffle 16 is fixedly connected to the side of the filter plate frame 4 away from the metal ring 18, the convex disc 15 is placed in the mounting groove 11 opened on the outside of the dust cover 3, and the outer edge of the convex disc 15 is provided with an arc protrusion 17, and the arc protrusion 17 contacts the baffle 16, the second motor 14 is installed on the outside of the dust cover 3, and the output end of the second motor 14 is fixedly connected to the convex disc 15. Under the action of the spring rod, the baffle 16 on the outside of the filter plate frame 4 will always be in contact with the convex disc 15, and when the second motor 14 drives the convex disc 15 to rotate, the arc protrusion 17 on the outer edge of the convex disc 15 will continuously push the baffle 16, and push the filter plate frame 4 toward the metal ring 18.

[0028] Specifically, the transmission mechanism includes a double-headed screw 8 disposed in the adjustment plate 1, the two ends of the double-headed screw 8 are rotatably connected to the two ends of the adjustment plate 1, a first motor 6 is disposed on the outside of the adjustment plate 1, the output end of the first motor 6 is fixedly connected to one end of the double-headed screw 8, two matching blocks 7 are sleeved on the outside of the double-headed screw 8, the two matching blocks 7 are respectively fixedly connected to the two dust hoods 3, and the two matching blocks 7 are separately matched with two threads provided on the outside of the double-headed screw 8. The double-headed screw 8 has two positive and negative threads on the outside, and the two matching blocks 7 are respectively threadedly connected to the positive and negative threads. When the first motor 6 drives the double-headed screw 8 to rotate, the double-headed screw 8 will drive the two matching blocks 7 to move along its shaft. Since the two threads on the outside of the double-headed screw 8 have different rotation directions, the two matching blocks 7 will move in opposite directions.

[0029] In order to improve the stability of the two dust hoods 3 when adjusting their positions, a limit plate 2 is provided on the side of the dust hood 3 away from the adjustment plate 1, and a guide rod 9 is provided inside the limit plate 2. The two ends of the guide rod 9 are fixedly connected to the two ends of the limit plate 2, and two guide blocks 10 are sleeved on the outside of the guide rod 9. The guide blocks 10 are slidably connected to the guide rod 9, and the two guide blocks 10 are respectively fixedly connected to the two dust hoods 3. The guide block 10 is fixedly connected to the side of the dust hood 3 away from the matching block 7. When the matching block 7 moves along the rod body of the double-headed screw 8, the guide block 10 fixed to the other end of the dust hood 3 will also move along the guide rod 9. The guide block 10 guides the dust hood 3 from the other end of the dust hood 3 by cooperating with the guide rod 9 to prevent the dust hood 3 from deflecting during adjustment.

[0030] The working principle of the present application is as follows: one of the two dust hoods 3 is placed above the processing table to remove dust from the area above the processing table, and the other is placed below the processing table to remove dust from the area below the processing table. The dust hood 3 is connected to the external negative pressure dust collection device through the dust collection air duct 5, and negative pressure is formed in the dust hood 3. The dust-laden airflow is drawn into the dust hood 3. When passing through the filter plate frame 4, the filter plate frame 4 will block large particles of debris in the air to prevent large particles of debris from blocking the dust collection air duct 5, and perform preliminary filtration on the airflow. When the filter plate frame 4 is full of dust, the reciprocating push assembly will push the filter plate frame 4 to shake in the dust hood 3, causing the filter plate frame 4 to collide with the striker structure. While the filter plate frame 4 is shaking, the knocking of the striker structure can ensure that the dust attached to the filter plate frame 4 falls off quickly, and the cleaning and maintenance are efficient.
