The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figures 1 to 4 As shown, this utility model provides a dust-removing wood chipper, including a chipper body 10. A feed conveyor belt 20 is connected to the input end of the chipper body 10, and a mounting frame 30 is provided above the output end of the feed conveyor belt 20. The mounting frame 30 is equipped with a folding and telescopic dust removal cover 40 that can be mounted on the feed inlet of the chipper body 10. The mounting frame 30 is also equipped with a folding fixing member 50 that can fix the folding and telescopic dust removal cover 40 in a folded state. The chipper body 10 is a wood chipper in the prior art, which will not be described in detail in this application. The folding and telescopic dust removal cover 40 can be freely extended and retracted. When it is necessary to adjust or clean the feed inlet, it can be folded and fixed without affecting operation; when working, it is unfolded to ensure dust removal effect.
[0023] See Figure 2 and Figure 3In a specific embodiment of this application, the folding telescopic dust cover 40 includes a top cover 41 mounted on a mounting frame 30. The mounting frame 30 is provided with accordion folding side panels 42 on both sides of the feed conveyor belt 20 at its lower end. A curtain 43 is provided on the lower end of the mounting frame 30 near the input end of the feed conveyor belt 20. The folding fastener 50 can fix the accordion folding side panels 42 in a folded state. The accordion folding cover 512 can be made of PVC or other materials to form a folding frame, and the hinges can be made of flexible materials such as rubber or three-proof fabric, which can refer to existing technology. The curtain 43 and the two sets of accordion folding side panels 42 form a three-sided enclosure outside the feed inlet of the feed conveyor belt 20. The curtain 43 can be made of flexible rubber strips, which hang naturally to enclose the feed end. When the wood is fed in, it can be pushed open to ensure that it will not obstruct the input wood. In order to enhance the dust interception capability, the installation height of the curtain 43 can also be reduced, that is, a section of accordion folding panel can be set above the curtain 43, which can be extended and folded with the accordion folding side panels 42 on both sides. Furthermore, a dust suction pipe 45 is connected to the top cover 41. The dust suction pipe 45 is connected to an external dust suction device. The dust suction device can be an existing negative pressure dust suction device.
[0024] See Figure 4 In one specific embodiment of this application, the folding fastener 50 includes two sets of first magnetic plates 51. The two sets of first magnetic plates 51 are respectively mounted on the lower end of the mounting frame 30 via tension springs 52 and are located outside the two sets of accordion folding side panels 42. Each set of accordion folding side panels 42 has a second magnetic plate 44 at its lower end that can cooperate with the first magnetic plates 51. The magnetic fastening method eliminates the need for complex mechanical structures, facilitates maintenance, and is suitable for long-term use in wood processing plants. Of course, hooks or buckles can also be used instead of magnetic fastening, but the magnetic method is more convenient to operate. When the accordion folding side panel 42 needs to be folded, the first magnetic plate 51 can be pulled down to stretch the tension spring 52 until it engages with the corresponding second magnetic plate 44. Under the reset action of the tension spring 52, the accordion folding side panel 42 can be folded upwards, making folding easier. Furthermore, both sides of the output end of the feed conveyor belt 20 are provided with a third magnetic plate 21 that can cooperate with the second magnetic plate 44, so as to magnetically fix the accordion folding side panel 42 in the extended state, that is, completely enclosing both sides of the output end of the feed conveyor belt 20.
[0025] In one specific embodiment of this application, the mounting frame 30 includes a column 31 installed on one side of the output end of the feed conveyor belt 20. The column 31 has a frame plate 32 extending above the output end of the feed conveyor belt 20. A dust suction port 33 is provided on the frame plate 32. A top cover 41 is installed above the dust suction port 33. The accordion-style folding side panel 42 and the curtain 43 are both located below the frame plate 32 and outside the dust suction port 33. To prevent large wood chips from entering the dust collection device and causing blockage, a slot 34 is provided on the side of the frame plate 32. A filter screen 35, capable of covering the dust suction port 33, is movably inserted into the slot 34. The filter screen 35 intercepts large wood chips, and is easy to remove for cleaning or replacement.
[0026] This utility model discloses a dust-removing wood chipper. Wood is fed into the chipper body 10 via a feed conveyor belt 20. A folding telescopic dust cover 40 is installed at the output end of the feed conveyor belt 20, i.e., at the feed inlet of the chipper body 10, to suck up the wood chips that are thrown out from the feed inlet during the chipping process, preventing dust pollution of the environment. The folding telescopic dust cover 40 can also be folded and extended, and is fixed in the folded state by a folding fastener 50, so that the feed inlet of the chipper body 10 can be exposed, making it convenient for workers to regularly clean and maintain the feed inlet of the chipper body 10.
[0027] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
