Description

Technical Field

[0001] This utility model belongs to the field of bamboo joint crushing technology, specifically relating to a bamboo joint crusher body with multi-stage blade linkage. Background Technology

[0002] Bamboo, a perennial herbaceous plant belonging to the Poaceae family and the Bambusa genus, has stems that are mostly woody, but can also be herbaceous, slightly hollow in the middle, and have many dense nodes. It typically grows to 5-10 meters tall, but some can reach over 40 meters. Bamboo leaves are narrowly lanceolate and dark green. Bamboo flowers resemble rice ears, with a predominantly yellow color. Flowering typically occurs in May, and fruiting in October. The bamboo node (or joint) refers to the protruding part connecting different sections of bamboo. Bamboo processing usually involves cutting the bamboo, but the nodes are quite hard after cutting, requiring crushing. In early or small-scale operations, people often first cut the nodes into small sections with knives or other tools, then fed them into simple crushing equipment. This equipment uses alloy steel hammers to repeatedly strike the nodes, finally discharging the crushed material. This method has low equipment requirements and is relatively simple to operate, but it is inefficient, has high labor costs, and the crushing effect is greatly affected by manual operation, resulting in uneven particle size. Therefore, it is difficult to meet the needs of large-scale production and high-precision processing, and thus requires improvement. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see Figure 1 and Figure 2As shown, a multi-stage bamboo shredder with interconnected blades includes a base 1. A shredding chamber 2 is fixedly connected to the top of the base 1. An adjustment chamber 3 is fixedly connected to the top surface of the shredding chamber 2. A first protective shell is fixedly connected to the inner bottom wall of the adjustment chamber 3. A first drive motor 4 is fixedly connected inside the first protective shell. A transmission rod 5 is fixedly connected to the output end of the first drive motor 4. A first gear 6 is fixedly connected to the bottom surface of the transmission rod 5. A track 7 meshes with the surface of the first gear 6. A rotating rod 8 is rotatably arranged inside the shredding chamber 2. A second gear is fixedly connected to the middle of the surface of the rotating rod 8, and the inner sidewall of the track 7 meshes with the surface of the second gear. Five first cutting tools are fixedly connected to the top surface of the rotating rod 8. The crushing chamber 2 has a cutting channel 10 inside the blade 9. The top of the inner wall of the cutting channel 10 is fixedly connected to the feed inlet 17. Five second cutting blades 11 are fixedly connected to the bottom of the surface of the rotating rod 8. A connecting rod is fixedly connected to the bottom of the rotating rod 8. Several third cutting blades 12 are fixedly connected to the surface of the connecting rod. A support plate is fixedly connected to the bottom of one side of the inner wall of the crushing chamber 2. A second protective shell is fixedly connected to one side of the bottom of the support plate. A second drive motor 13 is fixedly connected inside the second protective shell. A rotating rod is fixedly connected to the output end of the second drive motor 13. Several fourth cutting blades 14 are fixedly connected to the surface of the rotating rod, and the fourth cutting blades 14 and the third cutting blades 12 are interleaved.

[0022] The pulverizing chamber 2 allows the bamboo sections to be pulverized step by step within it. The first drive motor 4 provides a certain driving force for the rotation of the transmission rod 5. The rotation of the transmission rod 5 drives the first gear 6 to rotate, which in turn drives the track 7 to rotate, which in turn drives the second gear to rotate, which in turn drives the rotating rod 8 to rotate, ultimately causing the first cutting blade 9 to rotate. This initially pulverizes the bamboo sections that enter through the cutting channel 10, and then the second cutting blade 11 further pulverizes them. The rotation of the rotating rod 8 drives the connecting rod to rotate, which in turn causes the third cutting blade 12 to rotate, further pulverizing the bamboo sections. The output of the second drive motor 13 provides a certain driving force for the rotation of the rotating rod, thus enabling the fourth cutting blade to rotate. When the blade 14 rotates, the fourth cutting blade 14 and the third cutting blade 12 intersect, causing the bamboo joints to be crushed. Inside the crushing chamber 2, only the cutting channel 10 is vertically downward. At the same time, the rotating rod 8 and the connecting rod are both located on the right side inside the crushing chamber 2, and their interiors have grooves that match the size of the first cutting blade 9, the second cutting blade 11, and the third cutting blade 12 to facilitate the passage of the blades. Multiple grooves are provided on the left side of the crushing chamber 2 to facilitate the passage of the second cutting blade 11. One side of the bottom of the crushing chamber 2 is interconnected with the interior of the base 1 to facilitate the falling of the crushed bamboo joint fragments. The surface of the track 7 penetrates the interiors of the adjusting chamber 3 and the crushing chamber 2. Corresponding holes are provided at the connection between the adjusting chamber 3 and the crushing chamber 2 to facilitate the passage of the track 7.

[0023] Example 2:

[0024] Please see Figures 1 to 3 As shown, a sieve plate 15 is slidably connected to the bottom end of one side of the inner wall of the cutting channel 10, and a sieve screen 22 is provided inside the sieve plate 15. The sieve screen 22 is designed so that the broken fibers falling on it can easily fall downwards, while unqualified and uncrushed bamboo sections are blocked.

[0025] A guide port 16 is fixedly connected to the bottom of the surface of the crushing chamber 2. A third protective shell is fixedly connected to one side of the bottom wall of the crushing chamber 2. A third drive motor 18 is fixedly connected inside the third protective shell. A cam 19 is fixedly connected to the output end of the third drive motor 18. The guide port 16 facilitates the discharge of uncrushed bamboo sections for subsequent crushing.

[0026] A top rod 20 is fixedly connected to one side of the bottom of the screening plate 15, and the position of the bottom end of the top rod 20 corresponds to the position of the cam 19. The third drive motor 18 provides a certain driving force for the rotation of the cam 19. The rotation of the cam 19 causes the top rod 20 to vibrate up and down, so that the fibers and unbroken bamboo sections above it are screened.

[0027] A support rod is fixedly connected to the bottom end of one side of the inner wall of the cutting channel 10. One end of the support rod is fixedly connected to a guide sleeve 21, and the surface of the top rod 20 slides through the interior of the guide sleeve 21. The support rod allows the guide sleeve 21 to be positioned, and the guide sleeve 21 allows the top rod 20 to move up and down, providing a certain guiding and limiting function.

[0028] A sliding groove is provided on one side of the base 1, and a collection groove 23 is slidably connected inside the sliding groove. A handle is fixedly connected to the center of the surface of the collection groove 23, and an observation port 24 is provided in the center of the surface of the crushing chamber 2. The sliding groove makes it easy for the collection groove 23 to slide inside, and the collection groove 23 facilitates the collection of crushed fibers. The handle makes it easy to pull out the collection groove 23, and the observation port 24 allows the staff to observe the crushing of bamboo sections inside the crushing chamber 2.

[0029] A control panel is fixedly connected to the top of one side of the adjustment cavity 3, and the control panel is electrically connected to the first drive motor 4, the second drive motor 13 and the third drive motor 18 respectively.

[0030] The working principle of this utility model is as follows: The operator first places bamboo sections into the crushing chamber 2 through the feed inlet 17. Then, the operator controls the first drive motor 4, the second drive motor 13, and the third drive motor 18. The output of the first drive motor 4 drives the transmission rod 5 to rotate, which in turn drives the first gear 6 to rotate. The track 7 then rotates, causing the second gear to rotate. Finally, the rotating rod 8 drives the first cutting blade 9 to rotate, thus initially crushing the bamboo sections entering the cutting channel 10. The crushed bamboo sections continue to fall downwards, where they are further crushed by the second cutting blade 11. The second drive motor 13 drives the rotating rod to rotate, which in turn drives the fourth cutting blade 14 to rotate. The rotating rod 8, when rotating, drives... The connecting rod rotates, which in turn causes the third cutting blade 12 to rotate. The third cutting blade 12 and the fourth cutting blade 14 rotate alternately, further refining the bamboo joints after the two crushing processes, resulting in a better crushing effect. The crushed bamboo joint fibers that fall off will land on the screening screen 22. At this time, the third drive motor 18 will drive the cam 19 to rotate, which will cause the cam 19 to continuously push the top rod 20 upward. Meanwhile, the screening plate 15 will move up and down continuously, causing the crushed bamboo joint fibers that fall on it to shake and fall down, eventually landing inside the collection tank 23. The bamboo joint particles that are difficult to fall through the screening screen 22 are guided by the screening plate 15 to the guide port 16. Then, the staff can use a collection device to collect them at the bottom, which will facilitate subsequent crushing.
