The lower part of the gear shaft 126 is fixedly connected to the output shaft of the motor 190. The side of the motor 190 is fixedly connected to a motor base 191. The upper part of the motor base 191 is fixedly connected to the lower part of the workbench 110.

[0023] The lower part of the bow-shaped frame 130 has a lower bow-shaped frame hole 131, the upper part of the bow-shaped frame 130 has an upper bow-shaped frame hole 132, the right side of the lead screw 140 has a lead screw groove 141, the side of the lead screw groove 141 has a lead screw hole 142, the middle of the transmission shaft 150 has a transmission shaft hole 151, the right side of the transmission shaft hole 151 has a nut 152, the left side of the transmission shaft 150 has a friction cone 153, the right side of the transmission shaft 150 is rotatably connected to the transmission shaft holes 117 on both sides, the transmission shaft 150 rotates in the transmission shaft hole 117, the lead screw 140 is threadedly connected to the nut 152, the lower part of the bow-shaped frame 130 passes through the nut holder groove 116 from the right side, the lower bow-shaped frame hole 131 is hinged to the pin shaft 127, the upper part of the bow-shaped frame 130 is inserted into the lead screw groove 141, and the upper bow-shaped frame hole 132 is hinged to the gear hole 114.

[0024] The lower part of the funnel 160 has a blanking hole 161, the rear side of the funnel 160 has a connecting plate 162, the rear side of the connecting plate 162 has a funnel hole 163, the conveying shaft 170 axially has a spiral blade 172, the upper and lower sides of the conveying shaft 170 have rotating shafts 171, the middle of the stirring shaft 180 has a stirring shaft hole 181, the lower part of the stirring shaft 180 has a cross 182, and a plurality of blades 183 are evenly distributed at the lower part of each corner of the cross 182. The funnel hole 163 is fixedly connected to the middle part of the hopper rod 118, the blanking hole 161 and the positioning ring 111 are concentric, the outer side of the spiral blade 172 is rotatably connected to the inside of the blanking hole 161, the friction cone 153 is frictionally connected to the lower part of the spiral blade 172, the stirring shaft hole 181 is fixedly connected to the lower rotating shaft 171, the stirring shaft 180 is placed inside the hopper 120, the upper part of the spring 175 is sleeved on the spring shaft 119, and the lower part of the spring 175 is sleeved on the upper part of the rotating shaft 171.

[0025] When using the present invention, various ingredients of the feed are put into the funnel 160 in proportion, and the motor 190 is started. The rotation of the motor 190 drives the rotation of the gear 125, and the rotation of the gear 125 drives the rotation of the hopper 120. The rotation of the gear 125 drives the lead screw 140 to move left and right in the transmission shaft 150 through the bow-shaped frame 130, realizing intermittent continuous feeding, with more uniform stirring and higher efficiency, preventing the stirring shaft 180 from jittering and getting stuck due to uneven stress caused by too fast feeding. The left and right movement of the lead screw 140 drives the transmission shaft 150 to rotate clockwise and counterclockwise back and forth in the transmission shaft hole 117. When the transmission shaft 150 rotates clockwise, the friction cone 153 drives the spiral blade 172 to rotate clockwise, and the conveying shaft 170 rotates clockwise and rises along the feeding hole 161. When the transmission shaft 150 rotates counterclockwise, the friction cone 153 drives the spiral blade 172 to rotate counterclockwise, and the conveying shaft 170 rotates counterclockwise and descends along the feeding hole 161. When the conveying shaft 170 descends and rotates counterclockwise, the feed in the funnel 160 will be sent into the hopper. When the conveying shaft 170 rotates and rises and falls, it will drive the stirring shaft 180 to rotate and rise and fall. During the rotation and rise and fall of the stirring shaft 180, the feed in the hopper 120 will be stirred. After the stirring is completed, the sealing plate 129 is pulled, and the feed in the hopper 120 will leak out from the discharge port 113.

[0026] The present invention can achieve intermittent continuous feeding and continuous stirring, with high efficiency and uniform stirring. The power output of gear 125 completes all actions of the rotation of hopper 120, the lifting of stirring shaft 180, and stirring. Friction cone 153 outputs rotation to spiral blade 172, and spiral blade 172 simultaneously realizes two motions of lifting and forward and reverse rotation. Conveyor shaft 170 integrates feeding, stirring, and lifting. The components are closely connected and interact smoothly, preventing jamming, with balanced force and good balance, preventing the stirring shaft 180 from shaking due to uneven force caused by too fast feeding. When conveyor shaft 170 moves downward, it rotates to feed. When conveyor shaft 170 rises, it does not feed, providing a certain time for stirring to prevent too fast feeding and uneven stirring of the feed, and preventing the stirring shaft 180 from shaking due to uneven force caused by too fast feeding. Conveyor shaft 170 drives stirring shaft 180 to rotate and lift simultaneously. The lifting of stirring shaft 180 can complete the overall stirring of the feed in hopper 120. The lifting and forward and reverse rotation of stirring shaft 180 can make the feed stirring more sufficient and uniform. Multiple blades 183 stir together, making the stirring more efficient and uniform. The components interact smoothly, preventing jamming, with balanced force and good balance, preventing the stirring shaft 180 from shaking due to uneven force caused by too fast feeding and forming jamming. Spring 175 enables spiral blade 172 and friction cone 153 to have sufficient contact pressure, making the stirring more uniform and efficient. It increases the friction between friction cone 153 and spiral blade 172, enabling the power of friction cone 153 to be transmitted to spiral blade 172. The components interact smoothly, preventing jamming, with balanced force. Hopper 120 and blade 183 rotate relatively, forming a mixed flow state of the feed, making the stirring more uniform and efficient.

[0027] An operation method of an aquaculture feed mixing device includes the following steps:

[0028] First step: Put various ingredients of the feed into the funnel 160 in proportion and start the motor 190 to start stirring. Second step: After the stirring is completed, pull the sealing plate 129, and the feed in the hopper 120 will leak out from the discharge port 113. When using the present invention, put various ingredients of the feed into the funnel in proportion and start the motor. The rotation of the motor drives the gear to rotate, the rotation of the gear drives the hopper to rotate, the rotation of the gear drives the lead screw to move left and right in the transmission shaft through the bow-shaped frame, the left and right movement of the lead screw drives the transmission shaft to rotate clockwise and counterclockwise back and forth in the transmission shaft hole. When the transmission shaft rotates clockwise, the friction cone drives the spiral blade to rotate clockwise, and the conveying shaft rotates clockwise and rises along the blanking hole. When the transmission shaft rotates counterclockwise, the friction cone drives the spiral blade to rotate counterclockwise, and the conveying shaft rotates counterclockwise and descends along the blanking hole. When the conveying shaft rotates counterclockwise and descends, the feed in the funnel will be sent to the hopper. When the conveying shaft rotates and rises and falls, it will drive the stirring shaft to rotate and rise and fall. The process of the stirring shaft rotating and rising and falling will stir the feed in the hopper. After the stirring is completed, pull the sealing plate, and the feed in the hopper will leak out from the discharge port.
