Description
Technical Field
[0001] This utility model relates to the field of Poria cocos cultivation equipment technology, specifically a Poria cocos culture medium preparation device. Background Technology
[0002] Poria cocos is an important medicinal fungus, and its growth requires strict control over the proportion, uniformity, and physicochemical properties of the substrate. In the large-scale cultivation of Poria cocos, the substrate mixing device, as the core equipment, plays a crucial role. The main function of this device is to mix various raw materials such as pine sawdust, wheat bran, gypsum powder, sugars, and trace elements in specific proportions to ensure the uniform distribution of substrate components. The substrate mixing device typically consists of several parts, including a feeding system, a mixing chamber, a stirring device, a discharging system, and a control system. The feeding system is responsible for adding different types of raw materials to the mixing chamber in proportion, and the mixing chamber is the core area for material mixing, equipped with a stirrer to ensure thorough mixing of all components.
[0003] As disclosed in the patent announcement CN221693843U, a Poria cocos culture medium preparation device includes a feeding mechanism, a crushing chamber, and a discharging mechanism. The crushing chamber is equipped with a pulverizing mechanism and a screen. The screen is located below the pulverizing mechanism. The feeding mechanism extends above the pulverizing mechanism, and the discharging mechanism extends below the screen. The feeding mechanism conveys the raw materials to the area above the pulverizing mechanism within the crushing chamber. After being pulverized, the raw materials fall onto the screen below. Under the sieving action of the screen, incompletely pulverized raw materials are blocked, while properly pulverized raw materials fall onto the discharging mechanism below the screen, where they are collected. Since the culture medium does not contain large pieces of debris, the above-mentioned technical solution uses a belt conveyor to feed the proportioned pine sawdust, bran, gypsum powder, sugar, etc. into the crushing chamber. At this time, the physical properties of the raw materials such as pine sawdust, bran, gypsum powder, and sugar make them easy to adhere to the belt during transportation. In particular, powdery materials, due to their large surface area and poor flowability, are easily adhered to the belt under the action of friction and static electricity. At this time, granular and powdery materials will adhere to the belt surface and be sent out of the crushing chamber again, causing some materials to fall out or be missed during the feeding process. The leakage of materials will lead to an imbalance in the proportion of the mixed components, affecting the uniformity of the final base material. Utility Model Content
[0004] The purpose of this invention is to provide a Poria cocos culture medium preparation device. A direct drive motor drives a roller crusher and a belt feeder to work synchronously through a belt drive structure. During this process, a double-link driven scraper structure also receives the rotational power from the direct drive motor and scrapes off the material adhering to the lower surface of the belt feeder. The scraped material is then returned to the roller crusher through a return frame, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a Poria cocos culture medium preparation device, comprising a roller mill, a feeding frame installed at the top opening of the roller mill, and a belt feeder installed on one side of the top of the feeding frame. A belt drive structure for power connection is installed between the belt feeder and the roller mill. A direct drive motor for driving the roller mill is installed on one outer wall of the roller mill. A double-link driven scraper structure is installed on one side of the bottom of the belt feeder. A return frame is installed on the outer wall of the feeding frame below the double-link driven scraper structure. The return frame is used to reintroduce the material scraped off by the double-link driven scraper structure into the feeding frame. A second belt drive structure for power connection is installed between the roller mill and the double-link driven scraper structure.
[0006] Preferably, the roller crusher includes a crushing box installed at the bottom of the feed frame, two symmetrical crushing rollers rotatably installed inside the crushing box, and gears installed on the same end of the two crushing rollers, the two gears meshing with each other, and the drive shaft of the direct drive motor is fixedly connected to one end of one of the crushing rollers.
[0007] Preferably, one end of one of the crushing rollers drives a belt feeder through a pulley drive structure, and the other crushing roller drives a double-link driven scraper through a pulley drive structure.
[0008] Preferably, the outer wall of the feed frame near the return frame is provided with a perforated section for material to pass through.
[0009] Preferably, the double-link driven scraper structure includes a U-shaped shaft frame fixed to both sides of the bottom end of the belt feeder frame, a double-link guide frame, an I-beam slide table slidably mounted on the double-link guide frame, and a rotating shaft rotatably mounted inside the U-shaped shaft frame. Both ends of the rotating shaft are fixed with short connecting rods, and one end of the surface of the short connecting rod is hinged to a long connecting rod. One end of the long connecting rod is hinged to one side of the outer wall of the I-beam slide table. The top of the I-beam slide table is equipped with a scraper that extends upward and contacts the belt surface of the belt feeder. The other end of the U-shaped shaft frame is equipped with a gear transmission structure.
[0010] Preferably, the gear transmission structure consists of a primary gear shaft and a secondary gear shaft that mesh with each other. A tertiary gear that meshes with the secondary gear shaft is installed at one end of the rotating shaft surface. One end of the primary gear shaft extends through to the outside of the U-shaped shaft frame and is connected to one end of another crushing roller through a pulley transmission structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This Poria cocos culture medium preparation device drives a roller crusher and a belt feeder to work synchronously via a direct-drive motor and a belt drive structure. During this process, the double-link driven scraper structure also receives the rotational power from the direct-drive motor and scrapes off the material adhering to the lower surface of the belt feeder. The scraped material is then returned to the roller crusher through the return frame to avoid the leakage of materials such as pine sawdust, bran, gypsum powder, and sugar. The double-link driven scraper structure effectively scrapes off the material adhering to the lower surface of the belt, forming a closed loop during material conveying. After being scraped off, the material can quickly flow back into the crusher, forming a continuous material circulation. Secondly, the direct drive motor achieves synchronous operation of the roller crusher and the belt feeder through the pulley transmission structure, which greatly enhances the coordination between the two. In addition, the double-link driven scraping structure can automatically accept the power of the direct drive motor to work, reducing the need for manual intervention and making the switching between material conveying and crushing smoother, thereby improving the operating efficiency of the production line. Finally, in the material conveying process, by ensuring that all materials can be effectively conveyed into the roller crusher, the scraping structure helps to improve the uniformity and consistency of the final product.

A direct drive motor 3 for driving the roller mill 1 is installed on one outer wall of the roller mill 1. The roller mill 1 performs efficient material crushing and is suitable for materials with various hardness and properties.
[0020] A double-link driven scraper structure 7 is installed on one side of the bottom end of the belt feeder 4, and a return frame 6 is installed on the outer wall of the feed frame 2 below the double-link driven scraper structure 7. The return frame 6 is used to reintroduce the material scraped off by the double-link driven scraper structure 7 into the feed frame 2. A belt drive structure 2 8 for power connection is installed between the roller crusher 1 and the double-link driven scraper structure 7.
[0021] The direct drive motor 3 and the pulley drive structure 1 5 can effectively transmit power and ensure the smooth operation of the device. In this process, the design of the pulley can be adjusted according to the transmission ratio to adapt to different working conditions and load requirements. The pulley drive structure 1 5 and the pulley drive structure 2 8 can also be replaced with sprockets and chains for transmission.
[0022] The double-roll crusher 1 includes a crushing box installed at the bottom of the feed frame 2, two symmetrical crushing rollers rotatably installed inside the crushing box, and gears installed on the same end of the two crushing rollers. The two gears mesh with each other, and the drive shaft of the direct drive motor 3 is fixedly connected to one end of one of the crushing rollers.
[0023] One end of one of the crushing rollers drives the belt feeder 4 through the pulley drive structure 1 5, and the other crushing roller drives the double-link driven scraper structure 7 through the pulley drive structure 2 8. The outer wall of the feed frame 2 near the return frame 6 is provided with a hollow part for material to pass through. The feed frame 2 ensures that the material enters the roller crusher 1 evenly and avoids blockage caused by material accumulation.
[0024] The belt conveyor 4 quickly and continuously transports materials to the feed frame 2 and the roller crusher 1, reducing the workload of manual handling and improving production efficiency.
[0025] The double-link driven scraper structure 7 includes a U-shaped shaft frame 701 fixed to both sides of the bottom end of the belt feeder 4 frame, a double-link guide frame 702, an I-beam slide 703 slidably mounted on the double-link guide frame 702, and a rotating shaft 705 rotatably mounted inside the U-shaped shaft frame 701. Both ends of the rotating shaft 705 are fixed with short connecting rods 707. One end of the short connecting rod 707 is hinged to a long connecting rod 708. One end of the long connecting rod 708 is hinged to one side of the outer wall of the I-beam slide 703. The top of 03 is equipped with an upward-extending scraper 704 that contacts the belt surface of the belt feeder 4. The other end of the U-shaped shaft frame 701 is equipped with a gear transmission structure 706. The gear transmission structure 706 consists of a first-stage gear shaft and a second-stage gear shaft that mesh with each other. One end of the surface of the rotating shaft 705 is equipped with a third-stage gear that meshes with the second-stage gear shaft. One end of the first-stage gear shaft passes through to the outside of the U-shaped shaft frame 701 and is connected to one end of another crushing roller through the pulley transmission structure 8.
[0026] One of the crushing rollers in the double-roll crusher 1 drives the rotating shaft 705 to rotate via the belt drive structure 8 and the gear drive structure 706. The short connecting rod 707 rotates around the rotating shaft 705. During the rotation of the short connecting rod 707, it drives the I-beam slide 703 and scraper 704 to slide back and forth via the long connecting rod 708. The scraper 704 scrapes the material off the belt surface of the feed frame 2, allowing the material to enter the return frame 6. During this process, the double-rod guide frame 702 is used to guide the sliding of the I-beam slide 703 and scraper 704. Through effective scraping, the material residue and waste are reduced.
[0027] In this embodiment, the process begins by confirming that the materials to be processed, including but not limited to pine sawdust, bran, gypsum powder, and sugar, are ready and meet production requirements. The proportioned materials are then fed onto the belt conveyor 4. The direct drive motor 3 is then started. After starting, the direct drive motor 3 drives the belt conveyor 4 and the roller crusher 1 via the pulley transmission structure 5. At this time, the operator must observe the motor's operation to ensure smooth operation without abnormal noise, and adjust the speed of the direct drive motor 3 to ensure the materials are evenly fed into the feed frame 2. Once the belt conveyor 4 is running normally, the materials will enter the roller crusher 1 through the feed frame 2 and be mixed. The material is processed by combining and crushing. After entering the roller crusher 1, the double-link driven scraper structure 7 receives the rotational power from the roller crusher 1 through the belt drive structure 8, and actively scrapes off the material adhering to the lower surface of the belt conveyor 4, ensuring that no material is missed. At this time, the scraped material re-enters the roller crusher 1 through the feed frame 2. After the production task is completed, the staff must first stop the feeding of material. After the material in the roller crusher 1 has been processed, the direct drive motor 3 is gradually turned off. Finally, the belt conveyor 4, feed frame 2, roller crusher 1 and return frame 6 are cleaned to ensure that there is no residual material inside the device and to avoid cross-contamination of materials.
