Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically a mobile raw material feeder. Background Technology

[0002] In the large-scale production of soy products, soaking soybeans is a crucial pretreatment step. Its purpose is to allow the soybeans to fully absorb water and swell, laying the foundation for subsequent processing steps such as grinding and pulping. To ensure even and thorough soaking and avoid insufficient water absorption due to excessive stacking, the industry typically uses multiple soaking tanks or pools to soak soybeans in batches. Distributing the soybean quantity makes it easier to turn the soaking soybeans over, thereby improving the soaking quality. To further improve production efficiency and facilitate subsequent stirring and turning of soybeans in each soaking container using mechanical equipment (such as overhead cranes), factories typically arrange multiple soaking tanks or pools in a straight line. This arrangement allows the stirring device to move and rise along a straight line via overhead cranes or similar equipment, and then be inserted into each soaking container sequentially to complete the stirring operation, effectively ensuring the soaking effect of the soybeans. However, existing technologies have significant limitations when feeding rows of soaking tanks or pools. Currently, the industry mainly uses elevators or inclined conveyor belts for feeding. These devices have relatively fixed conveying paths and can typically only feed a single soaking tank or pool. When dealing with multiple soaking containers arranged in rows, frequent movement of the feeding equipment or manual transfer of soybeans is required to feed different containers. This not only increases the labor intensity of operators but also seriously affects feeding efficiency, thus hindering the continuous and automated production process of the entire soy product production line. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a mobile raw material feeder. The feeder uses a mobile hopper set above the frame to move along the straight direction of the frame, thereby facilitating the feeding of materials into the receiving hoppers arranged in rows below the frame. At the same time, the mobile hopper can be moved to the end to facilitate connection with an external elevator or inclined conveyor belt, thereby realizing the automated feeding process of soybeans. During the feeding process, a feeding baffle is set to facilitate the storage of soybeans in the mobile hopper and to move it to a suitable position for discharge. Combined with a vibration device, the soybeans can be discharged quickly.

[0004] This utility model is implemented by constructing a mobile raw material feeder, including a frame with a receiving hopper placed inside; The movable hopper is set above the frame and moves linearly along the length of the frame to discharge materials to various positions in the receiving hopper; A vibration device is installed at the bottom of the moving hopper to drive the moving hopper to vibrate and discharge materials; The discharge baffle is rotatably mounted on the discharge end of the mobile hopper to close or open the discharge end.

[0005] Preferably, the top of the frame is provided with a slide rail along the length direction, and a slide block is slidably installed on the slide rail. The movable hopper is a conical hopper with a flange on the outer side of the large end. The movable hopper is positioned above the slide block through the flange. There is a gap between the slide block and the flange of the movable hopper, and an elastic element is provided in the gap.

[0006] Preferably, a rack is provided on the top side wall of the frame along the length direction, a transmission rod is provided through the slide, the transmission rod is rotatably mounted on the slide and one end is provided with a gear that meshes with the rack, and the other end of the transmission rod is provided with a drive motor, the drive motor is fixed to the side wall of the slide and is connected to the transmission rod for transmission.

[0007] Preferably, a cylindrical discharge end is provided below the small end of the movable hopper. One end of the discharge baffle is rotatably disposed on the outer side of the cylindrical discharge end of the movable hopper. The other end of the discharge baffle is closed or opened by rotating to maintain contact or separation with the end of the cylindrical discharge end. A connecting rod is provided on the side of the discharge baffle. A linear telescopic device is provided on the outer side of the cylindrical discharge end of the movable hopper. The linear telescopic device is vertically disposed and its movable end faces downward. A horizontally arranged strip groove plate is provided at the movable end of the linear telescopic device. The connecting rod of the discharge baffle is engaged in the strip groove plate.

[0008] Preferably, there are multiple receiving hoppers, which are placed side by side with the frame along its length, and the opening of each receiving hopper is located below the discharge end of the moving hopper.

[0009] Preferably, the receiving hopper is divided into multiple placement areas by several partitions, and the partitions are perpendicular to the length direction of the frame.

[0010] This utility model has the following beneficial effects: 1. Enables continuous feeding of multiple containers, significantly improving feeding efficiency. This feeder, with its movable hopper, can move freely along the straight line of the frame, accurately aligning with each receiving hopper arranged in a row below the frame (and thus connecting to soaking tanks or soaking pools). It can complete the sequential feeding of multiple containers without frequent adjustments or movements of the overall feeding equipment, significantly shortening the feeding interval time, making the feeding process of rows of soaking containers more continuous, and effectively improving the overall rhythm of the production line.

[0011] 2. Reduce human intervention and promote automated production. The mobile hopper can be moved to the end to connect with an external elevator or inclined conveyor belt to automatically receive soybeans; at the same time, the storage and discharge of soybeans are controlled by the discharge baffle, reducing the manual transfer and dumping of soybeans, reducing the labor intensity of operators, and better meeting the automation requirements of large-scale production.

[0012] 3. Optimize material feeding to ensure production stability. The vibration device facilitates the rapid and smooth discharge of soybeans from the moving hopper, avoiding uneven or interrupted feeding caused by soybean accumulation and blockage. This ensures that each soaking tank or pool receives a fixed amount of soybeans, which is beneficial for the stable operation of subsequent soaking processes and improves the consistency of product quality.

[0013] 4. Adapts to existing production layouts and has strong compatibility. The device is designed around rows of soaking tanks or soaking pools. The movement trajectory of the frame and mobile hopper can be precisely matched with the existing container arrangement direction. It can coordinate with the operation path of agitation equipment such as overhead cranes without the need for large-scale modification of the original soaking area layout of the factory. This facilitates upgrades and modifications on the basis of existing production lines and reduces the cost and difficulty of equipment replacement. Attached Figure Description

[0017] As described in the background section, in the process of large-scale tofu production, existing food companies may need multiple soaking tanks when soaking soybeans, and these soaking tanks are usually arranged in a straight line, which is inconvenient for the soybean feeding operation.

[0018] For the reasons stated above, please refer to the appendix. Figure 1 ~Appendix Figure 3 This utility model provides a mobile raw material feeder, including a frame 1 with a receiving hopper 3 placed inside; The movable hopper 2 is positioned above the frame 1 and moves linearly along the length of the frame 1 to discharge materials into various positions within the receiving hopper 3. Vibration device 10 is installed at the bottom of the movable hopper 2 to drive the movable hopper 2 to vibrate and discharge materials; The discharge baffle 12 is rotatably mounted on the discharge end of the mobile hopper 2 to achieve the closing or opening of the discharge end.

[0019] The vibration device can be a vibration motor.

[0020] Please refer to the appendix carefully. Figure 1 ~Appendix Figure 3 To facilitate the linear movement of the mobile hopper on the frame and thus the feeding operation to the linearly distributed receiving hoppers, in this embodiment, a slide rail 4 is arranged along the length direction on the top of the frame 1, and a slide block 5 is slidably installed on the slide rail 4. The mobile hopper 2 is a conical hopper, and a flange is provided on the outer side of the large end of the mobile hopper 2. The mobile hopper 2 is set above the slide block 5 through the flange. There is a gap between the slide block 5 and the flange of the mobile hopper 2, and an elastic element 9 is provided in the gap.

[0021] To facilitate the automatic movement of the mobile hopper on the frame and achieve automated material unloading, while ensuring its fixation during unloading to prevent the mobile hopper from moving arbitrarily, in this embodiment, a rack 6 is provided along the length direction on the top side wall of the frame 1, and a transmission rod 7 is provided through the slide 5. The transmission rod 7 is rotatably mounted on the slide 5 and has a gear 8 at one end that meshes with the rack 6. The other end of the transmission rod 7 is provided with a drive motor 11, which is fixed to the side wall of the slide 5 and maintains a transmission connection with the transmission rod 7.

[0022] Please see the appendix Figure 4 and attached Figure 5 To facilitate the automatic opening and closing of the discharge baffle and thus the automatic discharge of the mobile hopper, in this embodiment, a cylindrical discharge end is provided below the small end of the mobile hopper 2. One end of the discharge baffle 12 is rotatably disposed on the outer side of the cylindrical discharge end of the mobile hopper 2. The other end of the discharge baffle 12 is closed or opened by rotating to maintain contact or separation with the end of the cylindrical discharge end. A connecting rod is provided on the side of the discharge baffle 12. A linear telescopic device 13 is provided on the outer side of the cylindrical discharge end of the mobile hopper 2. The linear telescopic device 13 is vertically disposed and its movable end faces downward. A horizontally arranged strip groove plate 14 is provided at the movable end of the linear telescopic device 13. The connecting rod of the discharge baffle 12 is engaged in the strip groove plate 14.

[0023] To facilitate material feeding to different locations within the receiving hopper, one possibility is that there are multiple receiving hoppers 3, which are placed side-by-side with the frame 1 along its length, with the opening of each receiving hopper 3 located below the discharge end of the movable hopper 2.

[0024] To facilitate material feeding to different locations within the receiving hopper, another possibility is that the receiving hopper 3 is divided into multiple placement areas by several partitions, with the partitions perpendicular to the length direction of the frame 1.

[0025] When discharging material, the feeder first activates a linear telescopic device (such as a cylinder, hydraulic cylinder, or electronic push rod that is easy to automate) to retract. This retraction is achieved by the strip-shaped groove plate 14 driving the discharge baffle 12 to rotate until it contacts the discharge end of the moving hopper 2, thus closing the connection. Subsequently, the drive motor 11 is activated, and the rotation of the transmission rod 7 drives the rotation of the gear 8. Due to the meshing of the rack 6, the slide 5 and the moving hopper 2 move linearly along the slide rail 4, facilitating material reception after connection to an external elevator or inclined conveyor. After receiving material for a preset time, the external elevator or inclined conveyor is shut down, and the drive motor 11 is activated. Motor 11 drives the mobile hopper to move above the corresponding receiving hopper 3 for material feeding. During feeding, the start of the drive motor 11 is stopped to ensure the mobile hopper 2 is fixed. Then, the linear telescopic device 13 extends and drives the feeding baffle 12 to flip through the strip groove plate 14. After the feeding baffle 12 separates from the discharge end at the bottom of the mobile hopper 2, the soybeans inside can be discharged. At the same time, the vibration device 10 is started to drive the entire mobile hopper 2 to vibrate, which facilitates rapid feeding. Because there is an elastic element 9 between the mobile hopper 2 and the slide 5, the vibration of the slide 5 can be reduced, ensuring the fixation of the slide 5 and the stability of the frame 1.

[0026] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
