Background
The wood has wide application, and is often applied to papermaking, textile, artificial boards and the like as raw materials of paper, cloth and artificial boards.
In the process of processing wood chips by a chipper for processing the wood into the wood chips, because of different varieties of the wood, the wood is different, the wood texture is sparse and compact, the loose texture wood is soft, the compact texture wood is hard, and the wood with different hardness can generate the wood chips with different sizes and be crushed into the wood chips with different sizes in the chipping process. This application discloses a wood chippings screening device, particularly for separating wood chips from the processed wood chips, which are contaminated with wood chips and therefore separated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the current problem, a timber screening plant of chipping is provided.
The utility model discloses a realize through following technical scheme: the utility model provides a timber chipping screening plant, the chipping machine is installed in one side top of frame, chipping machine's front side feed inlet department sets up the feed conveyer belt, and the conveyer belt is installed in the opposite side top of frame, and the discharge gate downside of chipping machine articulates the reel, tiling net piece in the reel, and the reel passes through the support to be supported on the bearing frame, and the inner of bearing frame is connected in the frame tip through the free bearing.
As a further improvement of the scheme, a flow plate is laid in the bearing frame, baffle plates are vertically arranged on two sides of the flow plate, the flow plate is used for screening a flow channel of sawdust falling from a net piece, and meanwhile the baffle plates are used for preventing the sawdust from scattering outwards in the flow process and limiting the flow direction of the sawdust.
As a further improvement to the scheme, the mesh shape of the net sheet is rectangular, the specification of the mesh sheet is 6-8mm, and the mesh sheet is used for screening the wood chips mixed in the wood chips.
As a further improvement of the scheme, an expansion piece for supporting is obliquely hinged between the lower part of the outer end of the bearing frame and the end part of the rack, and the outer end of the push-pull bearing frame is supported by utilizing the expansion piece.
As a further improvement to the above scheme, the telescopic part is one of an electric push rod or an air cylinder, and the main body of the electric push rod or the cylinder body of the air cylinder is mounted at the end part of the frame; the bearing frame can rotate around the hinged support at the inner end, so that the outer end of the bearing frame is inclined downwards, and the bearing frame can also support the gravity action of the bearing frame.
Compared with the prior art, the utility model has the following advantages: the wood chip screening and filtering device has the advantages that the structure is simple, the design is reasonable, the thought is novel and unique, wood chip scraps processed by the chipping machine flow to the vibrating mesh, the wood chip scraps are screened and filtered, meanwhile, the bearing frame can support the push-pull inclination through the telescopic piece, so that wood chips on the mesh after separation and the wood chips on the inclined trickling plate flow more smoothly, the baffle plates on the two sides of the trickling plate can avoid the wood chips from scattering everywhere, and the wood chips are guaranteed to flow to the outer low end of the trickling plate.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the mounting structure of the mesh.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-2, a wood chippings screening device, the chipper 2 is installed above the right side of the frame 3, a feeding conveyer belt 1 is arranged at the front side feed inlet of the chipper 2, the conveyer belt 1 is installed above the left side of the frame 3, a sieve frame 5 is hinged at the lower side of the discharge outlet 4 of the chipper 2, a mesh 12 is flatly laid in the sieve frame 5, the sieve frame 5 is supported on a bearing frame 7 through a support 6, and the inner end of the bearing frame 7 is connected to the end part of the frame 3 through a hinged support 8.
As a further improvement of the scheme, a dripping plate 10 is laid in the bearing frame 7, baffle plates 11 are vertically arranged on two sides of the dripping plate 10, the dripping plate 10 is used for screening a flow channel of the fallen sawdust from a net sheet 12, and the baffle plates 11 are used for preventing the sawdust from scattering outwards in the flowing process and limiting the flow direction of the sawdust.
As a further improvement to the above scheme, the mesh shape of the net sheet 12 is rectangular, and the size of the mesh is 6-8mm, and the mesh is used for screening the wood chips mixed in the wood chips.
As a further improvement to the above scheme, an expansion piece 9 for supporting is obliquely hinged between the lower part of the outer end of the bearing frame 7 and the end part of the frame 3, and the outer end of the push-pull bearing frame 7 is supported by the operation of the expansion piece 9.
As a further improvement to the above solution, the telescopic part 9 is one of an electric push rod or an air cylinder, and the main body of the electric push rod or the cylinder body of the air cylinder is mounted at the end of the frame 3; not only can the bearing frame 7 rotate around the hinged support at the inner end to ensure that the outer end of the bearing frame 7 inclines downwards, but also can support the gravity action of the bearing frame 7.
The working principle of the wood chipping and screening device is as follows: wood is placed on a feeding conveyer belt 1, feeding is carried out through the conveyer belt 1, the wood is fed into a chipper 2 for wood chip processing, the wood chips processed by the chipper 2 are discharged from a discharge hole of the wood chips and fall onto a net sheet 12, the net sheet 12 is vibrated by the vibration of the chipper 2 through a screen frame 5, and wood chips doped in the wood chips leak from meshes of the net sheet 12 and fall onto a trickling plate 10;
meanwhile, the outer ends of the screen frame 5 and the bearing frame 7 are inclined downwards under the action of the telescopic piece 9, and the wood chips on the net sheet 12 and the wood chips on the trickling plate 10 flow down to the outer ends thereof, so that the purpose of separation is realized.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
