Description

Technical Field

[0001] This utility model relates to the field of biomass crushers, specifically a crusher for biomass pellet processing. Background Technology

[0002] A biomass pellet crusher is a mechanical device specifically designed for biomass raw materials. Its main function is to pre-process biomass raw materials such as sawdust, straw, wheat straw, corn stalks, reeds, waste paper, feed, and various agricultural products. These materials are fed into the machine through the inlet, where they are effectively crushed into smaller particles or powder by the impact, shearing, and tearing action of blades or hammers. This process not only improves the efficiency of subsequent processing but also ensures the quality of the final pellet fuel and promotes resource reuse, which is of great significance to the biomass energy industry. The crushed raw materials are then discharged through the outlet, fully prepared for the next process, such as crushing, drying, and pelleting. A search of patent number "202223583498.8" for "A Raw Material Crusher for Biomass Pellet Processing" reveals that this utility model includes a crushing tank with a feed inlet at the top. One end of the feed inlet extends into the interior of the crushing tank. Symmetrically arranged movable plates are positioned inside the feed inlet, with one end of each plate rotatably connected to the inner walls on either side of the feed inlet. This utility model features movable plates that can rotate within the feed inlet. When material falls onto the movable plates, they rotate downwards, causing a connecting rod to push a sliding rod out of the feed inlet, allowing the material to enter the crushing tank. When there is no material on the movable plates, a spring releases its elastic potential energy, causing the two movable plates to close together via the connecting rod. This prevents crushed material from flying out of the feed inlet during the crushing process, thus solving the problem of existing crushers lacking protective devices and causing residue to fly out of the feed inlet during the crushing process.

[0003] However, the aforementioned patents still have some significant problems. For example, since the movable baffle needs to be reset using springs, and these springs are mainly located on both sides of the machine body, during long-term use, some debris will still fly out from the outlet during crushing. This debris will stick to the springs. Over time, the accumulation of debris will not only increase the weight of the springs and affect their elasticity, but may also cause the springs to jam or fail, thereby affecting the normal rotation and closure of the movable baffle, reducing the reliability and service life of the equipment. At the same time, the maintenance and cleaning of the springs is also an additional workload, requiring regular shutdowns for cleaning and inspection. This not only increases operating costs, but may also affect the continuity and efficiency of the production line. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a crusher for biomass pellet processing, so as to solve the technical problems in the prior art caused by the spring reset mechanism, such as debris accumulation, decreased spring performance, affected rotation and closure of the moving plate, reduced equipment reliability, shortened service life, increased product contamination risk, and increased operating costs and maintenance burden.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crusher for biomass pellet processing, comprising a machine body, a feed inlet, and a blocking mechanism, wherein the blocking mechanism comprises a movable baffle, a first connecting rod, a second connecting rod, a sliding rod, and a return spring, and a protective mechanism is provided on the outside of the return spring;

[0006] The protective mechanism includes a fixed rod, which is mounted on the machine body. A mounting ring is provided at the top of the fixed rod, and a first folding cover and a second folding cover are respectively provided on both sides of the mounting ring.

[0007] The outer side of the first folding cover is provided with external threads, and a cover is screwed onto the external threads. The cover abuts against one end of the slide rod.

[0008] One end of the second folding cover is attached to the fuselage.

[0009] By adopting the above technical solution, the material entry and exit are effectively controlled by the blocking mechanism, while the protective mechanism protects key components such as the return spring, thereby improving the overall durability and safety of the equipment.

[0010] Furthermore, the first folding cover and the second folding cover can be used to cover the return spring, and the cover covers the return spring and the slide rod.

[0011] By adopting the above technical solution, key components such as the return spring and slide bar are fully protected, preventing the intrusion of external impurities and debris, thereby extending the service life of the equipment and reducing maintenance requirements.

[0012] Furthermore, the first and second folding covers are made of plastic.

[0013] By adopting the above technical solutions, plastic materials are lightweight, durable, and low in cost, while also possessing good flexibility and corrosion resistance, making them suitable for use in equipment with harsh working environments, such as crushers.

[0014] Furthermore, the movable baffle is rotatably connected to the inner wall of the feed inlet, and the bottom of the movable baffle is rotatably connected to the first connecting rod via a connecting seat.

[0015] By adopting the above technical solution, the movable baffle can rotate flexibly at the feed inlet, thereby effectively controlling the entry and obstruction of materials, and improving the operational flexibility and control accuracy of the equipment.

[0016] Furthermore, a connecting groove is provided at the bottom of the first connecting rod, and a second connecting rod is rotatably connected in the connecting groove. A sliding rod is provided at the end of the second connecting rod away from the connecting groove, and the sliding rod passes through the machine body and extends to the outside of the machine body.

[0017] By adopting the above technical solution, a stable transmission mechanism is formed, which can transmit power from the inside of the machine body to the outside, realize remote or automated control of the movable baffle, and improve work efficiency.

[0018] Furthermore, an adjusting plate is screwed to one end of the slide rod, and two auxiliary rotating plates are provided on one side of the adjusting plate.

[0019] By adopting the above technical solution, the design of the adjusting plate and the auxiliary rotating plate allows the position and angle of the slide rod to be easily adjusted, thereby achieving precise control over the opening and closing degree of the movable baffle. At the same time, the auxiliary rotating plate can also reduce jamming and resistance during movement.

[0020] Furthermore, a return spring is provided on the inner side of the adjusting plate, and the return spring is elastically connected to the adjusting plate.

[0021] By adopting the above technical solution, the reset spring provides a stable rebound force for the movable baffle, ensuring that the movable baffle can quickly and accurately return to its original position after being opened, thereby improving the working efficiency and stability of the equipment.

[0022] Furthermore, a motor housing is provided on one side of the machine body, and a feed inlet is provided on the top of the machine body.

[0023] By adopting the above technical solution, the motor housing provides a power source for the crusher, enabling the equipment to work continuously and stably.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by setting up a protective mechanism, wherein the first and second folding covers tightly cover the reset spring and further seal the sliding rod connection through the cover, effectively isolates the debris and dust generated during the crushing process. In particular, the two layers of folding covers are ingeniously designed, which can not only tightly wrap the reset spring, but also flexibly adjust their shape with the movement of the sliding rod and the spring, ensuring that the normal extension and contraction of the spring is not affected. Moreover, it effectively prevents the accumulation of debris on the reset spring, reduces the risk of spring jamming and performance degradation, provides a clean and interference-free working environment for the reset spring, ensures the stability of its elastic performance, and thus improves the rotation accuracy of the movable baffle and the overall reliability of the equipment. By reducing the damage of debris to the spring, the service life of the spring is extended, the cost of downtime maintenance and spring replacement is reduced, and the operating and maintenance burden is reduced. At the same time, the protective mechanism also isolates the product from the contamination of debris and dust, solving the technical problems of debris accumulation, spring performance degradation, affected rotation and closure of the movable plate, reduced equipment reliability, shortened service life, increased product contamination risk, and increased operating costs and maintenance burden caused by the spring reset mechanism.

[0026] 2. This utility model incorporates a blocking mechanism. The movable baffle, connected to the inner wall of the feed inlet via a rotatable connection, effectively controls the material's entry and exit, preventing sharding and backflow. Simultaneously, a connecting groove at the bottom of the first connecting rod rotatably connects to the second connecting rod. Together with a sliding rod penetrating the machine body, this forms a stable and efficient transmission mechanism. This ensures precise control of the movable baffle, reduces friction and wear between moving parts, and improves the equipment's durability. The adjustment plate and auxiliary rotating plate at one end of the sliding rod allow for easy adjustment of its position and angle, enabling precise control of the movable baffle's opening and closing degree. The auxiliary rotating plate further ensures smooth sliding rod movement, effectively reducing jamming and resistance. Furthermore, a return spring inside the adjustment plate provides stable rebound force to the movable baffle, ensuring it quickly and accurately returns to its original position after opening.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A crusher for biomass pellet processing, such as Figures 1-4 As shown, the crusher includes a machine body 1, a feed inlet 3, and a blocking mechanism 4. The blocking mechanism 4 includes a movable baffle 401, a first connecting rod 402, a second connecting rod 403, a sliding rod 405, and a return spring 408. A protective mechanism 5 is provided on the outside of the return spring 408. The protective mechanism 5 includes a fixed rod 501, which is mounted on the machine body 1. A mounting ring 502 is provided on the top of the fixed rod 501. A first folding cover 503 and a second folding cover 506 are respectively provided on both sides of the mounting ring 502. An external thread 504 is provided on the outside of the first folding cover 503, and a cover 505 is screwed onto the external thread 504. The cover 505 abuts against one end of the sliding rod 405. One end of the second folding cover 506 is adhered to the machine body 1. This design ensures that the blocking mechanism 4 can flexibly and stably control the material in and out during operation of the crusher. At the same time, the protective mechanism 5 provides effective protection for the return spring 408, reducing damage caused by external factors and extending the service life of the equipment.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first folding cover 503 and the second folding cover 506 can be used to cover the return spring 408, and the cover 505 covers the return spring 408 and the slide bar 405. This double-cover design not only prevents the return spring 408 and the slide bar 405 from being exposed to the harsh working environment, but also reduces the failure caused by the accumulation of debris, dust and other impurities, and improves the reliability and maintenance convenience of the equipment.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The first folding cover 503 and the second folding cover 506 are made of plastic. The choice of plastic material makes the folding covers lightweight, corrosion resistant, easy to mold and replace, reducing the overall weight and manufacturing cost of the equipment, while ensuring the protective effect.

[0038] Example 2:

[0039] See Figure 1 , Figure 2 , Figure 3 The movable baffle 401 is rotatably connected to the inner wall of the feed inlet 3. The bottom of the movable baffle 401 is rotatably connected to the first connecting rod 402 through the connecting seat. This rotatable connection method allows the movable baffle 401 to flexibly open and close the feed inlet 3, which facilitates the control of material flow and crushing process, and improves the operational flexibility and working efficiency of the equipment.

[0040] See Figure 1 , Figure 2 , Figure 3 The bottom of the first connecting rod 402 is provided with a connecting groove 404, and a second connecting rod 403 is rotatably connected in the connecting groove 404. A sliding rod 405 is provided at the end of the second connecting rod 403 away from the connecting groove 404, and the sliding rod 405 passes through the body 1 and extends to the outside of the body 1. This design realizes a stable transmission chain, which can effectively transmit power from the inside of the body 1 to the movable baffle 401, while ensuring the accuracy and reliability of the transmission and reducing failures caused by wear of transmission components.

[0041] See Figure 1 , Figure 2 , Figure 3 One end of the slide bar 405 is screwed with an adjusting plate 406. Two auxiliary rotating plates 407 are provided on one side of the adjusting plate 406.

The first folding cover 503 and the second folding cover 506 are respectively set on both sides of the mounting ring 502. They adopt a foldable design and can tightly cover the outside of the return spring 408. This design not only ensures the comprehensiveness of the protection, but also allows the folding cover to flexibly adjust its shape with the movement of the return spring and the slide rod 405, avoiding interference or damage caused by the displacement of moving parts.

[0045] The outer side of the first folding cover 503 is provided with an external thread 504, and the cover 505 screwed to it can further seal the connection between the return spring 408 and the slide rod 405. This design not only enhances the tightness of protection, but also effectively isolates the debris and dust generated during the crushing process, preventing them from entering the working area of ​​the return spring, thereby avoiding spring jamming or performance degradation caused by debris accumulation.

[0046] One end of the second folding cover 506 is bonded to the machine body 1. This connection method ensures the stability of the folding cover and facilitates installation and maintenance. At the same time, both the first folding cover 503 and the second folding cover 506 are made of plastic. This material is not only lightweight and durable, but also has good flexibility and corrosion resistance, and can withstand the test of the crusher's working environment for a long time.

[0047] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
