Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, specifically a crushing and utilization device. Background Technology

[0002] The re-drying and rolling process generates a large amount of waste, including residues, dust, and tobacco stems. These wastes have lost their value in cigarette manufacturing. In the past, waste tobacco leaves were generally destroyed by burning or watering to prevent unscrupulous merchants from passing off inferior products as superior ones. However, direct burning produces a large amount of smoke and dust, while watering and landfilling pollutes groundwater. Therefore, the country now advocates for more environmentally friendly methods to treat waste tobacco leaves (such as crushing them and making tobacco blocks to replace coal for flue-cured tobacco). This method can both destroy the waste tobacco leaves and make greater use of their value.

[0003] Traditional crushing devices typically employ a single rotating blade or hammer-type structure, which suffers from low crushing efficiency, high energy consumption, and susceptibility to clogging. Especially for materials with complex compositions or high toughness, conventional crushing methods often fail to achieve uniform crushing, resulting in uneven particle size and affecting subsequent processing. Furthermore, existing equipment has weak separation capabilities, often requiring additional screening devices for grading the crushed material, increasing process complexity and equipment costs. Therefore, we propose a crushing and utilization device. Utility Model Content

[0004] The purpose of this invention is to provide a crushing and utilization device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing and utilization device, comprising a crushing box, a feeding hopper at the top of the crushing box, a box cover installed on the top of the crushing box, and a support shaft rotatably connected to the bottom center of the box cover via a bearing, crushing blades equidistantly installed on the outer side of the support shaft, a drive shaft rotatably arranged at equidistant distances on the bottom of the box cover outside the support shaft, and a spiral cutting blade connected to the outer side of the drive shaft, a separation plate slidably arranged at the bottom of the inner wall of the crushing box, an opening at the bottom of the crushing box, and a conical cylinder at the bottom of the separation plate.

[0006] Preferably, a driven gear is fixedly connected to the top of the support shaft through the cover, and a transmission gear is fixedly connected to the top of the transmission shaft through the cover, with adjacent transmission gears meshing with each other. A drive motor is fixedly installed on the top of the cover, and a drive gear is fixedly connected to the end of the output shaft of the drive motor. The drive gear meshes with the transmission gear and the driven gear respectively.

[0011] Preferably, observation windows are symmetrically arranged on the outer side of the fragmentation box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model adopts a dual crushing structure of coarse crushing by central crushing blades and fine crushing by spiral cutting blades. The material is first cut into larger pieces by high-speed rotating crushing blades, and then finely sheared by spiral cutting blades, so that materials with different hardness and toughness can be fully crushed, avoiding the problem of uneven particle size caused by traditional single-stage crushing, and improving the crushing efficiency and finished product quality of tobacco leaves.

[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] Please see Figure 1 This utility model provides a technical solution: a crushing and utilization device, including a crushing box 1, a feeding hopper 3 at the top of the crushing box 1, a box cover 2 installed on the top of the crushing box 1, and a support shaft 4 rotatably connected to the bottom center of the box cover 2 via a bearing, crushing blades 5 are equidistantly installed on the outer side of the support shaft 4, a transmission shaft 6 is rotatably arranged at the bottom of the box cover 2 on the outer side of the support shaft 4, and a spiral cutting blade 7 is connected to the outer side of the transmission shaft 6, a separation plate 12 is slidably arranged at the bottom of the inner wall of the crushing box 1, an opening is provided at the bottom of the crushing box 1, and a conical cylinder 13 is provided at the bottom of the separation plate 12.

[0021] Please see Figure 1 and Figure 3 The top of the support shaft 4 passes through the cover 2 and is fixedly connected to the driven gear 9. The top of the transmission shaft 6 passes through the cover 2 and is fixedly connected to the transmission gear 8. The two adjacent transmission gears 8 are meshed and connected. The top of the cover 2 is fixedly installed with the drive motor 11, and the output shaft end of the drive motor 11 is fixedly connected to the drive gear 10. The drive gear 10 is meshed and connected to the transmission gear 8 and the driven gear 9 respectively.

[0022] It should be noted that when using this utility model, the tobacco material to be processed is fed into the crushing box 1 from the feeding hopper 3. After the box cover 2 is closed, the crushing process can be ensured to be safe and dustproof. A vent is provided at the top of the box cover 2, and a dust filter screen is provided in the vent to prevent dust from leaking out. The device is equipped with a controller, which controls the operation of the drive motor 11. The drive motor 11 drives the drive gear 10 to rotate, which in turn meshes with the driven gear 9 to make the support shaft 4 rotate, which drives the crushing blade 5 on it to rotate at high speed, so as to perform preliminary coarse crushing of the material and cut it into larger pieces. The drive gear 10 simultaneously meshes with multiple transmission gears 8, so that the transmission shaft 6 drives the spiral cutter 7 to rotate. Because adjacent transmission gears 8 mesh with each other, each spiral cutting blade 7 rotates in opposite directions, generating shearing force to perform secondary crushing of the material, ensuring that the material is fully crushed to the required particle size. The crushed material falls to the separation plate 12, and the vibration motor 14 starts, driving the conical cylinder 13 and the separation plate 12 to vibrate at high frequency under the buffering effect of the support spring 21. This allows the qualified particle size material to fall through the screen holes of the separation plate 12, and the qualified crushed material enters the conical cylinder 13 and is finally discharged from the discharge cylinder 15. The electric control valve 16 can adjust the discharge speed. The material that does not meet the standard continues to remain in the crushing box for secondary crushing until it meets the requirements. The annular convex plate 20 and the support spring 21 provide buffering to reduce the impact of vibration on the overall equipment and improve stability. Throughout the entire operation, the crushing of tobacco leaves can be monitored in real time through the observation window 19.

[0023] Please see Figure 1 and Figure 2 The inner wall of the crushing box 1 at one end of the opening is integrally provided with an annular convex plate 20. The top of the annular convex plate 20 is fixedly connected with a support spring 21 at equal intervals, and the top of the support spring 21 is fixedly connected with the separation plate 12.

[0024] It should be noted that the annular convex plate 20 and the support spring 21 provide cushioning, reduce the impact of vibration on the overall equipment, and improve stability.

[0025] Please see Figure 1 A mounting base is symmetrically fixed to the outer side of the conical cylinder 13, and a vibration motor 14 is fixedly installed inside the mounting base.

[0026] It should be noted that the operation of the vibration motor 14 can drive the conical cylinder 13 and the separation plate 12 to vibrate at high frequency under the buffering effect of the support spring 21, so that the material with qualified particle size falls through the screen holes of the separation plate 12.

[0027] Please see Figure 3 A ring frame 17 is fixed to the bottom of the outer side of the crushing box 1, and three support legs 18 are equidistantly arranged at the bottom of the ring frame 17.

[0028] It should be noted that the coordinated arrangement of the ring frame 17 and the support leg 18 achieves the purpose of providing stable support for the crushing box 1.

[0029] Please see Figure 2 The bottom of the conical cylinder 13 is integrally provided with a feeding cylinder 15, and an electric control valve 16 is installed on the outside of the feeding cylinder 15.

[0030] It should be noted that the conical cylinder 13 is designed to store the crushed material, which is then discharged at the feed cylinder 15. The electric control valve 16 can adjust the discharge speed.

[0031] Please see Figure 3 Observation windows 19 are symmetrically arranged on the outer side of the fragmentation box 1.

[0032] It should be noted that the observation window 19 is designed to allow personnel to observe the crushing process inside the crushing chamber 1 in real time, and to adjust the equipment operating parameters according to the crushing process.

[0033] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.
