Description

Technical Field

[0001] This utility model relates to the field of chippers, and more specifically, to a drum chipper. Background Technology

[0002] Drum chippers are specialized equipment for producing industrial wood chips. They consist of a high-strength steel plate welded body, a cutter roller, upper and lower feeding mechanisms, and a hydraulic system. This equipment can cut logs, small-diameter timber, branches, and other raw materials into industrial wood chips with smooth cuts and uniform dimensions. It is widely used in paper mills, particleboard factories, fiberboard factories, and wood chip production bases. It can also process non-wood fiber stalks such as bamboo and cotton stalks as raw materials for artificial boards.

[0003] Existing drum chippers use a hydraulic system to change the blade spacing to produce chipped products of three to five centimeters in size. However, due to the limitations of the blade structure, the feeding space cannot be further adjusted. When it is necessary to produce thinner and smaller products such as wood chips and wood shavings to meet the needs of applications such as mushroom cultivation and fertilizer production, it is necessary to stop the machine to replace the blades or connect the conveyor line to other chippers, which affects production efficiency and has insufficient applicability. To solve the above problems, a drum chipper is proposed. Utility Model Content

[0024] 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 a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this 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.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The specific embodiments are as follows: like Figures 1 to 5 As shown, a drum chipper includes a frame 1. A first drive assembly 2 is fixedly installed on the outer wall of the frame 1. A driven cutting component 3 is sleeved on the outside of the first drive assembly 2. A second drive assembly 4 is fixedly installed on the outer wall of the frame 1. A control assembly 6 is fixedly installed on the top of the frame 1. A third drive assembly 7 is fixedly installed on the outer wall of the frame 1 away from the first drive assembly 2. A material collection frame 8 is slidably installed on the inner wall of the frame 1. The control assembly 6 includes an electric push rod 60, which is fixedly installed on the top of the frame 1. A movable guide plate 61 is hinged to the telescopic end of the electric push rod 60. A rotating rod 62 is fixedly installed on the outer wall of the frame 1, and a rotating rod seat 12 is fixedly installed on the inner wall of the frame 1. The rotating rod 62 is rotatably connected to the inside of the rotating rod seat 12. A fixed guide plate 14 is fixedly installed on the inner wall of the frame 1. Two guide plates 15 are fixedly installed on the top of the fixed guide plate 14. A vertical guide plate 13 is fixedly installed on the inner wall of the frame 1. The first drive assembly 2 is used to transmit materials and drive one of the cutting parts. The second drive assembly 4 is responsible for driving the other cutting part to chip wood or bamboo. The third drive assembly 7 additionally controls the crushing part of the crushed material as an optional processing method. It should be noted that the third drive assembly 7 includes a third drive motor 70, the output end of the third drive motor 70 is coaxially connected to a main shaft 71, a main shaft wheel 72 is fixedly installed on the outside of the main shaft 71, a main shaft drive belt 73 is sleeved on the outside of the main shaft wheel 72, a driven shaft wheel 74 is attached to the inner wall of the main shaft drive belt 73, a driven shaft 75 is fixedly installed inside the driven shaft wheel 74, an active grinding roller 76 is fixedly installed on the outside of the main shaft 71, a driven grinding roller 77 is fixedly installed on the outside of the driven shaft 75, and several bearings 11 are provided on the inner wall of the frame 1. One end of the driven shaft 75 and the main shaft 71 both pass through the outer wall 1 of the frame and are rotatably connected to the bearings 11. When it is necessary to process the material for secondary processing to obtain wood chips, wood chips and bamboo chips, etc., the material needs to be guided between the active grinding roller 76 and the driven grinding roller 77 through the control assembly 6. The material is then crushed into finer particles through secondary crushing and will accumulate in the material collection box 8. Furthermore, the first drive assembly 2 includes a first drive motor 20, which is fixedly mounted on the outer side wall of the frame 1. The first drive motor 20 is coaxially connected to a feed shaft 21. A feed roller 23 is fixedly mounted on the outside of the feed shaft 21, and a drive wheel 22 is fixedly mounted on the outside of the feed shaft 21. A driven cutting component 3 is sleeved on the outside of the drive wheel 22. A bearing seat 10 is fixedly mounted on the outer side wall of the frame 1. The end of the feed shaft 21 away from the first drive motor 20 is rotatably connected to the bearing seat 10. The driven cutting component 3 includes a transmission belt 33, which is sleeved on the drive wheel 21. Outside of frame 2, a driven wheel 30 is attached to the inside of the transmission belt 33. A cutting shaft 31 is fixedly installed inside the driven wheel 30. One end of the cutting shaft 31 passes through the outer wall of the frame 1 and is rotatably connected to the receiving bearing 11. A lower chipping roller 34 is fixedly installed outside the cutting shaft 31. When the first drive motor 20 drives the feeding shaft 21 and the feeding roller 23 to rotate, the drive wheel 22 outside the feeding shaft 21 will drive the driven wheel 30, the cutting shaft 31 and the lower chipping roller 34 to rotate together through the transmission belt 33, so that the feeding roller 23 transmits the material while the lower chipping roller 34 performs cutting. The second drive assembly 4 includes a second drive motor 40, which is coaxially connected to an upper chipping roller 41. The end of the upper chipping roller 41 away from the second drive motor 40 is rotatably connected to a receiving bearing 11. The second drive assembly 4 drives the upper chipping roller 41 to cooperate with the lower chipping roller 34 to chip the raw material transmitted by the feed roller 23.

[0026] like Figure 6 , 7 As shown in Figure 8, the vertical guide plate 13 is located on the side of the lower chipping roller 34 and the upper chipping roller 41 away from the feed roller 23. The fixed guide plate 14 is located below the lower chipping roller 34 and the vertical guide plate 13. The end of the movable guide plate 61 away from the rotating rod seat 12 is in contact with the fixed guide plate 14. The active grinding roller 76 and the driven grinding roller 77 are both located below the fixed guide plate 14 and the movable guide plate 61. The material collection frame 8 is located below the active grinding roller 76 and the driven grinding roller 77. When the raw material is chipped, it will be cut into pieces of three to five centimeters in size by the saw teeth after passing through the upper chipping roller 41 and the lower chipping roller 34. At the same time, it will be limited by the vertical guide plate 13 and fall above the fixed guide plate 14. When the fixed guide plate 14 and the movable guide plate 61 are in contact, the finished product will slide directly into the material collection frame 8 and accumulate. It should be noted that when it is necessary to produce finer finished products such as wood chips and wood scraps, the electric push rod 60 pushes one end of the movable guide plate 61 downward. At this time, the other end of the movable guide plate 61 is connected to the rotating rod seat 12 through the rotating rod 62, thus causing it to move. This creates a gap between the fixed guide plate 14 and the movable guide plate 61 for the material to fall. At the same time, the third drive motor 70 starts to drive the driven roller 77 and the active roller 76 to rotate to perform secondary processing on the material. Since the gap between the active roller 76 and the driven roller 77 is smaller and there are no cutting blades, the extruded material is in a finer shape to meet different production needs. Finally, the material also slides into the collection frame 8 and accumulates.

[0027] Working principle: The first drive component 2 and the second drive component 4 can chip the material to produce a sheet-like product. When it is necessary to produce a smaller product, the control component 6 causes the movable guide plate 61 to move, changing the movement trajectory of the sheet material and allowing it to undergo secondary processing through the third drive component 7. The sheet material after secondary processing will be even smaller.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
