Description

Technical Field

[0001] This utility model relates to the field of forestry crushing, and more specifically, to a multi-functional crushing device for forestry waste. Background Technology

[0002] Forestry production generates a large amount of waste. If this waste is not properly disposed of, it will not only occupy land resources but may also pollute the environment. Proper disposal can improve the utilization rate of waste, reduce resource waste, reduce environmental pollution, and promote sustainable development.

[0003] A search revealed that Chinese patent CN221288142U discloses "a forestry waste shredder, comprising a shredder body, a feeding assembly for conveying raw materials connected to the upper part of the shredder body, and a discharging assembly for conveying crushed materials provided at the lower part of the shredder body. The shredder body includes a shell, and a shredding assembly is provided inside the shell. Three movable screens are provided below the shredding assembly. A power assembly connected to the shredding assembly is provided outside the shell. The feeding assembly includes a bottom plate, and side plates are provided on both sides of the bottom plate. The bottom plate and the side plates form a feeding channel for raw materials to pass through. The angle between the feeding channel and the feeding port at the top of the shell is an obtuse angle, and the connection point is inclined at a certain angle. The discharging assembly forms an inverted triangular space with a conveyor belt and the discharging port shell, effectively avoiding material blockage and improving discharge efficiency." However, the following defects still exist:

[0004] (1) The screen is located below the crushing component. When the material is not crushed enough, it needs to be put back into the feeding component for crushing. The operation is repeated and time is wasted.

[0005] (2) The feeding speed and the processing speed of the crushing component are not coordinated. If too much material is fed, the crushing component cannot process it in time, resulting in accumulation.

[0006] Therefore, we have made improvements to this and proposed a multi-functional crushing device for forestry waste. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1-5 As shown, this embodiment proposes a multi-functional crushing device for forestry waste, including a shell 1, a screen 2 bolted inside the shell 1, and a crushing mechanism 3 provided on one side of the screen 2;

[0035] like Figure 1-3 As shown, the crushing mechanism 3 includes a first servo motor 301, a rotating shaft 302, a rectangular disk 303, blades 304, and a limiting ring 305. The first servo motor 301 is fixedly installed on the outside of the housing 1. The rotating shaft 302 is fitted to the output end of the first servo motor 301 and supported on the housing 1 by bearings. The rectangular disk 303 is fixedly installed on the rotating shaft 302. The blades 304 are bolted between two adjacent sets of rectangular disks 303, and there are four sets of blades 304, which are evenly distributed in the circumference. The limiting ring 305 is located on one side of the rectangular disk 303 and is penetrated by the rotating shaft 302. After the first servo motor 301 is started, the rotating shaft 302 drives the rectangular disk 303 and the blade 304 to rotate at high speed, which shears and crushes the material entering the housing 1. The screen 2 is arranged close to the outer edge of the blade 304. After crushing, the material is thrown towards the screen 2 by centrifugal force. When the size of the crushed material is larger than the aperture of the screen 2, the material will be crushed a second time by the blade 304 until its size meets the standard of the screen 2 and then discharged. It is convenient to operate and simple to use, which can greatly improve work efficiency.

[0036] like Figure 4As shown, a second servo motor 4 is installed on the outer side of the housing 1. A compression roller 5 is installed at the output end of the second servo motor 4. Multiple sets of racks 6 are fixedly connected to the periphery of the compression roller 5. The racks 6 are elongated. The second servo motor 4 serves as a power source, driving the compression roller 5 to rotate through its output end, thus compressing and pre-treating the incoming material. The multiple sets of racks 6 fixedly connected to the periphery of the compression roller 5 embed into the material, which can fix the material and assist in the subsequent crushing work. At the same time, the rotation speed of the compression roller 5 can be adjusted in real time according to the crushing progress.

[0037] like Figure 1 As shown, a protective plate 8 is provided on one side of the housing 1. A third servo motor 9 is installed on the outer side of the protective plate 8. A first rotating roller 10 is installed at the output end of the third servo motor 9. The first rotating roller 10 passes through the protective plate 8 and is connected to the bearing of the protective plate 8. A second rotating roller 11 is installed in the bearing inside the protective plate 8. A belt 12 is tensioned and installed on the outer side of the second rotating roller 11. The first rotating roller 10 and the second rotating roller 11 are connected by the belt 12. After the third servo motor 9 is started, the first rotating roller 10 starts to rotate, and the second rotating roller 11 rotates synchronously through the belt 12. The third servo motor 9 can adjust the speed in real time according to the processing requirements of the crusher, thereby controlling the conveying speed of the belt 12, which helps to improve the degree of automation and enhance stability.

[0038] like Figure 1 As shown, a discharge port 13 is provided at the bottom of the housing 1, and a control panel 14 is fixedly installed on the outside of the housing 1. The inner wall of the discharge port 13 is smooth, which can prevent the accumulation of materials. The crushed materials fall naturally to the discharge port 13 under the action of gravity, while reducing dust rising.

[0039] like Figure 1 As shown, three sets of support columns 15 are welded to the bottom of the shell 1, and anti-slip pads 16 are fixedly installed at the bottom of the support columns 15. Four sets of upright columns 17 are welded to the bottom of the guard plate 8. The support columns 15 at the bottom of the shell 1 form a stable support structure, effectively resisting the vibration and impact during crushing operations. The upright columns 17 form a rectangular support surface to ensure the stability of the conveyor belt during operation.

[0040] like Figure 1 As shown, a first connecting block 18 is bolted to the side of the housing 1, and the other end of the connecting block is bolted to the side of the guard plate 8. A second connecting block 19 is bolted to the side of the support column 15, and one end of the second connecting block 19 is bolted to the side of the column 17. The guard plate 8 can be separated as needed, and can be quickly replaced when the guard plate 8 is damaged. The assembly is flexible and the operation is simple.

[0041] like Figure 1As shown, multiple sets of anti-slip strips 20 are fixedly installed on the surface of the belt 12. The multiple sets of anti-slip strips 20 are evenly distributed on the belt 12, which can increase the contact area with the material, improve the gripping force, effectively prevent the material from slipping back, and facilitate user use.

[0042] Specifically, when using this multi-functional forestry waste crushing equipment: the operator starts the third servo motor 9 through the control panel 14, and the belt 12 starts to run, conveying the material to the shell 1. The second servo motor 4 serves as the power source, driving the extrusion roller 5 to rotate through its output end, compressing and pre-treating the incoming material. After the material enters the shell 1, the first servo motor 301 drives the rotating shaft 302 to drive the blade 304 group to rotate at high speed, shearing and crushing the material. When the size of the crushed material is larger than the aperture of the screen 2, the material will be crushed a second time by the blade 304 until its size meets the passing standard of the screen 2, and then it will be naturally discharged through the discharge port 13. The inner wall of the discharge port 13 is smooth, which can avoid the accumulation of material. The crushed material falls naturally under the action of gravity, while reducing dust rising. When it is necessary to replace the guard plate 8 or perform maintenance, it is only necessary to disassemble the first connecting block 18 and the second connecting block 19.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
