Description

Technical Field

[0001] The utility model belongs to the technical field of wood processing, and particularly relates to a waste crushing device for wood processing. Background Technique

[0002] Wood processing technology includes basic processing technologies such as wood cutting, wood drying, wood gluing, and wood surface decoration, as well as functional treatment technologies such as wood protection and wood modification. Cutting methods include sawing, planing, milling, drilling, and sanding. During the wood processing process, waste will be generated. If these wastes are not properly processed, it will not only cause waste of resources but also pollute the environment. Common treatment methods include mechanical recycling method, incineration power generation method, organic fertilizer manufacturing method, and biomass energy utilization method.

[0003] The mechanical recycling method is a method of using special machinery and equipment to process, process, and recycle wood waste. It can decompose wood waste into particles or slices of different sizes. Waste crushing is one of the methods. At present, when the existing waste crushing device crushes waste, it generally cannot achieve a 100% crushing effect. At this time, it is necessary for workers to pour the initially crushed waste back into the crushing device for secondary crushing. However, this method not only wastes manpower but also has low efficiency.

[0004] Therefore, we provide a waste crushing device for wood processing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a waste crushing device for wood processing. By repeatedly and automatically performing a crushing process on the waste, the waste with a small size in the crushed waste can fall into the collection box through the through holes, and the waste with a large size cannot pass through the through holes and continues to fall into the conveying groove and is conveyed by the conveying auger to the crushing groove for secondary crushing. Compared with manually taking out the waste and pouring it into the feeding chute for secondary crushing, it is more convenient and labor-saving, and solves the problem that the existing method of manually pouring the initially crushed waste back into the crushing device for secondary crushing not only wastes manpower but also has low efficiency.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a waste crushing device for wood processing, comprising a processing box; the processing box is provided with mutually connected conveying troughs, crushing troughs, collecting troughs and feeding troughs; the inner wall of the crushing trough is respectively provided with a first crushing assembly and a plurality of second crushing assemblies; a linkage assembly is provided between the first crushing assembly and the second crushing assembly; the second crushing assembly comprises a plurality of rotating rods arranged in parallel with each other; a connecting rod is fixed at both ends of each rotating rod; a mounting shaft is fixed on the peripheral side of the connecting rod; the mounting shaft is rotatably matched with the inner wall of the crushing trough; a plurality of connecting shafts are fixed on the inner wall of the crushing trough; a plurality of rolling balls are rotatably provided on the rotating rod and the peripheral side of the connecting rod; a conveying auger is rotatably provided on the inner wall of the conveying trough; a collecting frame is plugged and matched with the inner wall of the collecting trough.

[0008] The utility model is further configured as follows: the first crushing assembly includes a plurality of crushing rollers rotatably arranged on the inner wall of the crushing groove; a crushing gear is fixed to one end of the crushing roller; each of the crushing gears is meshed and matched; and a plurality of through holes are opened through the inner wall of the processing box.

[0010] The utility model is further configured as follows: two rotating shafts are symmetrically arranged between the inner walls of the crushing trough; a baffle is fixed to the circumferential side of the rotating shaft; an adjusting gear is fixed to one end of the rotating shaft; under the configuration of the rotating shaft and the baffle, the rotating shaft can drive the baffle to rotate and thereby control the size of the discharge opening.

[0011] The utility model is further configured as follows: two mounting plates are symmetrically fixed on the side of the processing box; a reciprocating screw is rotatably arranged between the two mounting plates; an I-shaped plate is arranged on the side surface of the reciprocating screw; a rotating groove is opened through the surface of the I-shaped plate; a sliding block is arranged on the inner wall of the rotating groove and slides with the thread groove of the reciprocating screw.

[0016] 2. When the two adjusting racks of the present utility model slide up and down, they drive the corresponding adjusting gears to rotate in opposite directions respectively, thereby driving the two rotating shafts to rotate in opposite directions, and then driving the two baffles to approach or move away from each other.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0028] See also Figures 1-5 The utility model is a waste crushing device for wood processing, comprising a processing box 1; the processing box 1 is provided with a conveying trough 2, a crushing trough 3, a collecting trough 4 and a feeding trough 5 which are interconnected; the inner wall of the crushing trough 3 is provided with a first crushing assembly and a plurality of second crushing assemblies; a linkage assembly is provided between the first crushing assembly and the second crushing assembly; the second crushing assembly comprises a plurality of rotating rods 6 which are arranged in parallel with each other; a connecting rod 7 is fixed at both ends of each rotating rod 6; a mounting shaft 8 is fixed on the side surface of the connecting rod 7; the mounting shaft 8 is rotatably matched with the inner wall of the crushing trough 3; a plurality of connecting shafts 9 are fixed on the inner wall of the crushing trough 3; a plurality of rolling balls 10 are rotatably provided on the side surfaces of the rotating rod 6 and the connecting rod 7; a conveying auger 11 is rotatably provided on the inner wall of the conveying trough 2; a collecting frame 12 is plugged and matched with the inner wall of the collecting trough 4.

[0029] Specifically, the first crushing assembly includes a plurality of crushing rollers 13 rotatably arranged on the inner wall of the crushing trough 3 ; a crushing gear 14 is fixed to one end of the crushing roller 13 ; the crushing gears 14 are meshed and matched; and a plurality of through holes 30 are opened through the inner wall of the processing box 1 .

[0030] Furthermore, the linkage assembly includes a first pulley 15 fixed at one end of the crushing roller 13 and one end of the mounting shaft 8 respectively; a first belt 16 is arranged for transmission between the two first pulleys 15; a first servo motor 17 is fixed to the side of the processing box 1; and the output end of the first servo motor 17 is fixedly connected to the first pulley 15.

[0031] The operation process of this embodiment is as follows: First, pour the waste materials from the feeding chute 5 into the interior of the treatment box 1. The waste materials with smaller sizes first fall into the interior of the collection box 12 through the through holes 30, and the remaining large-volume waste materials slowly fall into the conveying chute 2. The conveying auger 11 transports the waste materials from the bottom of the conveying chute 2 to the top of the conveying chute 2 and then drops them into the crushing chute 3. Turn on the first servo motor 17 to drive the first pulley 15 to rotate. Through the transmission of the first belt 16, drive another first pulley 15 to rotate, and then the linkage assembly works. The linkage assembly drives the first crushing assembly and the second crushing assembly to work together.

[0032] The waste materials are first crushed by the crushing rollers 13, and then the preliminarily crushed waste materials fall downward to reach the second crushing assembly. The mounting shaft 8 of the second crushing assembly is driven by the first pulley 15 to rotate, and then drives the rotating rod and the connecting rod 7 to rotate. During the rotation process, the rolling balls 10 contact and rub against each other to further crush the waste materials. At the same time, during the rotation of the second crushing assembly, the amount of waste materials falling can be controlled to prevent all the waste materials from accumulating at the bottom of the crushing chute 3. Among the waste materials crushed for the first time, those with smaller sizes can fall into the collection box 12 through the through holes 30, and the waste materials with larger sizes cannot pass through the through holes 30 and continue to fall into the conveying chute 2 and are transported by the conveying auger 11 to the crushing chute 3, repeating the above crushing process.

[0033] In this embodiment, the waste materials can be broken repeatedly and automatically. Among the crushed waste materials, those with smaller sizes can fall into the collection box 12 through the through holes 30, and the waste materials with larger sizes cannot pass through the through holes 30 and continue to fall into the conveying chute 2 and are transported by the conveying auger 11 to the crushing chute 3 for re-crushing. Compared with manually taking out the waste materials and pouring them into the feeding chute 5 for re-crushing, it is more convenient and labor-saving. Specific Embodiment Two

[0035] Please refer to Figures 1-5 , on the basis of Specific Embodiment One, two rotating shafts 18 are symmetrically and rotatably arranged between the inner walls of the crushing chute 3; a baffle 19 is fixed on the circumferential side of the rotating shaft 18; one end of the rotating shaft 18 is fixed with an adjusting gear 20; with the arrangement of the rotating shaft 18 and the baffle 19, the rotating shaft 18 can drive the baffle 19 to rotate to control the size of the material outlet.

[0036] Specifically, two mounting plates 21 are symmetrically fixed on the side surface of the treatment box 1; a reciprocating lead screw 22 is rotatably arranged between the two mounting plates 21; a shaped plate 23 is arranged on the circumferential side of the reciprocating lead screw 22; a rotating groove 24 is formed through the surface of the shaped plate 23; a sliding block that is slidably matched with the thread groove of the reciprocating lead screw 22 is arranged on the inner wall of the rotating groove 24.

[0037] Furthermore, adjusting racks 25 are symmetrically fixed on the side surface of the shaped plate 23; the adjusting racks 25 are meshed and matched with the adjusting gears 20.

[0038] Further, a second pulley 26 is fixed to one end of the reciprocating lead screw 22 and one end of the conveying auger 11; a second belt 27 is drivingly arranged between the two second pulleys 26; an L-shaped fixing plate 28 is fixed to the surface of the processing box 1; a second servo motor 29 is fixed to the inner top surface of the L-shaped fixing plate 28; and the output end of the second servo motor 29 is fixedly connected to the second pulley 26.

[0039] The operation process of this embodiment is as follows: The second servo motor 29 drives the second pulley 26 together with the conveying auger 11 to rotate, drives another second pulley 26 to rotate through the driving action of the second belt 27, further drives the reciprocating lead screw 22 to rotate, further drives the slider to slide along the thread groove of the reciprocating lead screw 22, further drives the I-shaped plate 23 to slide up and down, and further drives the adjusting rack 25 to slide up and down.

[0040] When the two adjusting racks 25 slide up and down, they respectively drive the corresponding adjusting gears 20 to rotate in opposite directions, further drive the two rotating shafts 18 to rotate in opposite directions, and further drive the two baffles 19 to approach or separate from each other. When the baffles 19 approach each other, the feeding port of the first crushing assembly for the waste material becomes smaller; when the baffles 19 separate from each other, the feeding port of the first crushing assembly for the waste material becomes larger. Thus, the amount of waste material fed can be controlled to prevent blockage inside the processing box 1 and damage to the machine.
