[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] like Figures 1-5 As shown, the mobile forced feeder of this embodiment includes a base 1, on which a mobile feeding platform 2 is installed. A feeding module for forced feeding of the cooker is installed above the mobile feeding platform 2. A guide rail 3 is laid on the upper part of the base 1, and a pulley 4 that works with the guide rail 3 is installed on the lower part of the mobile feeding platform 2. A drive module for moving the mobile feeding platform 2 is installed in the middle of the base 1. The drive module can drive the feeding module away from or near the cooker. After the forced feeding is completed, the feeding module separates from the cooker, ensuring that the cooker is in a completely sealed state during operation, ensuring the pressure stability inside the cooker, and reducing the steam consumption of the cooker during use without affecting the feeding efficiency.

[0022] The drive module includes a cylinder 5, and the fixed end of the cylinder 5 is connected to a drive source 6. The drive source 6 is an air compressor, which provides power for the extension and retraction of the cylinder 5. The extension and retraction end of the cylinder 5 is connected to the moving material table 2, which is used to drive the feeding module to move. The drive module can also be a hydraulic cylinder or a motor.

[0023] The base 1 has a storage groove 7 for mounting the cylinder 5 in the middle along the length of the base 1. The lower part of the movable platform 2 is provided with a push plate 8 connected to the telescopic end of the cylinder 5. The upper part of the storage groove 7 is provided with a guide groove 9 corresponding to the position of the push plate 8. The guide groove 9 and the push plate 8 can play a secondary guiding role to ensure the stability of the movable platform 2 during movement.

[0024] The feeding module includes a feeding cylinder 10, inside which a conveying auger 11 is installed. A drive motor 12 for driving the conveying auger 11 to rotate is installed at one end of the feeding cylinder 10. The diameter and length of the feeding cylinder 10 are selected according to the specifications of the cooker. In order to adapt to different feeding lengths, the feeding cylinder 10 is composed of multiple short pipes connected end to end. Each short pipe has a flange at both ends, and two adjacent short pipes are fastened with bolts for easy disassembly and assembly.

[0025] A reducer 13 is installed between the drive motor 12 and the conveying auger 11. A coupling 14 is provided between the output end of the reducer 13 and the conveying auger 11. An integral bearing seat 17 is provided at the connection between the coupling 14 and the conveying auger 11 to ensure the stability of the transmission.

[0026] The top of the feeding cylinder 10 is provided with a feeding port 15, and a feeding hopper 16 is installed around the feeding port 15. The material is conveyed into the feeding hopper 16 by a conveyor, and then the material is transferred into the cooker by a conveying auger 11.

[0027] The feeding hopper 16 is formed by combining four steel plates. One steel plate, which is far away from the drive motor 12, is installed vertically, while the other three steel plates are designed in a trumpet shape. This design is to avoid the front steel plate from colliding with the feed inlet of the cooker during use. The vertical design can avoid collisions and keep the feed hopper 16 parallel to the front of the cooker. It can also limit the movement and prevent the material from deviating from the feeding point of the feeding hopper 16 due to excessive movement.

[0028] The working principle / assembly process of this solution is as follows: When the cooker needs to be fed, the material is conveyed to the feed hopper 16 by the belt conveyor, and then transferred to the cooker by the conveying auger 11. In this operating state, the feeding cylinder 10 is inserted into the feed cylinder of the cooker. After feeding is completed, the material platform 2 is moved away from the cooker, so that the feeding cylinder 10 is separated from the cooker. Then the sealing valve of the cooker is closed, and the cooker starts to operate.
