[0024] See Figure 1-2 This utility model provides a feeder that facilitates quick and easy replacement of the screw, including: a mixing chamber 10, a material trough 20, a base 40, a motor 60, a reducer 70, and a flip-open transmission box 90. The lower part of the mixing chamber 10 is directly connected to the material trough 20. The mixing chamber 10 is equipped with a mixing shaft 11, and the material trough 20 is equipped with a screw shaft 21. The material trough 20 and the transmission box 90 are mounted on the base 40.

[0025] One side wall of the transmission box 90 consists of two parts connected by a flip shaft, and the other side wall consists of two parts connected by an openable structure. The motor 60 housing is fixed to the reducer 70 housing, and the reducer 70 housing is fixed to the openable wall of the transmission box 90.

[0026] The motor 60 drives the dual-output shaft transmission mechanism 30 in the transmission box 90 through the reducer 70. The dual-output shaft transmission mechanism 30 is installed on the openable box wall of the transmission box 90. The dual-output shaft transmission mechanism 30 includes a driving wheel 31 and a driven wheel 32. The driving wheel 31 and the driven wheel 32 are sprockets. The driving wheel 31 and the driven wheel 32 are driven by a chain 33. The reducer 70 drives the driving wheel 31.

[0027] The rotating shaft of the drive wheel 31 drives the stirring shaft 11 through an openable first claw coupling, and the driven wheel 32 drives the screw shaft 21 through an openable second claw coupling.

[0028] One side wall of the transmission box 90 consists of two parts connected by a flip shaft, and the other side wall consists of two parts connected by an openable structure. This allows the dual-output shaft transmission mechanism 30, motor 60, and reducer 70 of the transmission box 90 to form a flipable module that can be separated from the screw shaft 21 and stirring shaft 11.

The tension wheel bracket 52 rotates around the tension wheel fixed shaft 51. The tension wheel bracket 52 drives the tension wheel shaft 54 ​​and the tension sprocket 55. The tension sprocket 55 abuts and meshes with the chain 33. The tension sprocket 55 can better fit and mesh with the chain 33, and make the chain 33 taut as a whole when the chain 33 is in motion, making the transmission more stable.

[0030] A protective plate 80 is hinged to the base 40, and the protective plate 80 rotates along the vertical plane. First, close the openable walls of the transmission box 90, then rotate the protective plate 80 upwards, as shown. Figure 1 In this state, the protection plate 80 is located on the outside of the transmission box 90, and the protection plate 80 plays a protective role for the transmission box 90.

[0031] Junction box 81 and wiring rod 82 are installed on the protection board 80 for guiding the line, laying the cable, and connecting the wires.

[0032] The stirring shaft 11 is connected to and installed with a stirring rod, which is located in the stirring chamber 10.

[0033] The screw shaft 21 is connected to the screw rod, which is located in the feed trough 20.

[0034] When the staff needs to replace the stirring shaft 11, screw shaft 21, and screw, the box wall of the transmission box 90 is opened, and the dual output shaft transmission mechanism 30, motor 60, and reducer 70 are separated from the stirring shaft 11 and screw shaft 21 and moved away, so that the staff can easily disassemble and assemble the stirring shaft 11, screw shaft 21, and screw.

[0035] In summary, this utility model of a feeder that facilitates quick screw replacement features a transmission box with a switchable wall, forming a flip-up module that separates the dual-output shaft transmission mechanism, motor, and reducer from the screw shaft and agitator shaft. This allows for easy disassembly and replacement of the agitator shaft, screw shaft, and screw.
