[0024] In practical implementation: such as Figures 1-5 As shown, a feeding device for culture medium includes: a feeding hopper 100 and a conveying bag 200; a feeding mechanism 300, which includes a reciprocating assembly 380 and a fixed frame 310 fixedly connected to the bottom end of the feeding hopper 100. The bottom end of the fixed frame 310 is connected to a circular tube 320. The top end of the conveying bag 200 is installed at the bottom end of the circular tube 320. A plurality of evenly distributed mounting plates 330 are rotatably connected to the inner wall of the fixed frame 310. One end of the rotating shaft of the mounting plate 330 passes through the fixed frame 310 and is fixedly connected to a gear 340. A lead screw 360 is rotatably connected to one side of the fixed frame 310. A sliding frame 370 is threadedly connected to the surface of the lead screw 360. A sliding rod 371 is slidably connected to the top end of the sliding frame 370. A rack 350 that meshes with the plurality of gears 340 is fixedly connected to the top end of the sliding rod 371.

[0025] In this embodiment, the top opening of the feeding bag 200 can be fixed to the bottom opening of the round tube 320 by a clamp, which is the same as in the original solution. An installation rod is fixedly connected to the inner wall of the round tube 320, and a second motor is fixedly connected to the top of the installation rod. The output shaft of the second motor passes through the installation rod and is fixedly connected to a spiral blade. When the culture medium is fed, the second motor is started by the controller, which will drive the spiral blade to rotate. This method is the same as in the original solution.

[0026] When multiple mounting plates 330 are in a horizontal position, they will form an integral sealing plate, and the surface of the integral sealing plate will fit against the inner wall of the fixing frame 310.

[0027] like Figure 2 and Figure 3 As shown, the reciprocating assembly 380 includes a first motor 381 fixedly connected to one side of the fixed frame 310. The output shaft of the first motor 381 is fixedly connected to a reciprocating screw 382. A movable frame 383 is provided on the surface of the reciprocating screw 382. A movable rod 384 is slidably connected to the top of the movable frame 383. The top of the movable rod 384 is fixedly connected to the bottom of the rack 350. A fixed block 385 is fixedly connected to one side of the top of the movable frame 383. A threaded rod 386 is threadedly connected to the inner wall of the fixed block 385. A threaded hole 387 is opened on the surface of the movable rod 384.

[0028] In the embodiment, in the initial state, the moving frame 383 does not move towards the first motor 381, the moving rod 384 does not move in the moving frame 383 away from the first motor 381, and the threaded rod 386 is not connected with the threaded hole 387, so that the rack 350 is driven to move horizontally by the sliding frame 370 and the sliding rod 371, and the moving rod 384 is driven to move horizontally in the moving frame 383.

[0029] As shown in Figure 4 , the surface of the sliding frame 370 and the surface of the sliding rod 371 are provided with fixing holes 372, and the inner wall of the fixing hole 372 is slidably connected with a clamping rod 373.

[0030] In the embodiment, the fixing hole 372 on the surface of the sliding frame 370 is located in the middle of the sliding frame 370, and in the initial state, the clamping rod 373 is clamped with the fixing hole 372 of the sliding frame 370 and the sliding rod 371, so as to fix the sliding rod 371 and the sliding frame 370, and thus the sliding rod 371 is driven to move synchronously when the sliding frame 370 is driven to move by rotating the lead screw 360.

[0031] It should be noted that when the moving frame 383 returns to the initial state during use of the device, the fixing hole 372 of the sliding rod 371 coincides with the fixing hole 372 of the sliding frame 370, so that the clamping rod 373 can be clamped with the fixing hole 372 of the sliding frame 370 and the sliding rod 371 again.

[0032] As shown in Figure 3 , one side of the rack 350 is fixedly connected with a sliding block 351, and the surface of the sliding block 351 is slidably connected with the inner wall of the fixed frame 310. The fixed frame 310 is provided with a sliding groove matched with the sliding block 351 on one side.

[0033] As shown in Figure 5 , the inner bottom wall of the fixed frame 310 is fixedly connected with a guide plate 312, and the surface of the guide plate 312 is curved in an arc shape.

[0034] In the embodiment, the outer surface of the guide plate 312 is fixedly connected with the inner wall of the fixed frame 310, and the opening diameter of the bottom end of the guide plate 312 is the same as the opening diameter of the bottom end of the fixed frame 310, so that the culture medium in the fixed frame 310 flows downward better.

[0035] As shown in Figure 5 , the transparent plate 311 is embedded and installed on the upper end of one side of the fixed frame 310.

[0036] In the embodiment, the transparent plate 311 is arranged above the horizontal plane of the plurality of mounting plates 330, so that the staff can better observe the inclination angle of the mounting plate 330.

[0037] As shown in Figure 4As shown, one end of the screw rod 360 is fixedly connected with a knob 361, and the surface of the knob 361 is fixedly connected with a plurality of fixed rods distributed in a ring shape. The staff is more labor-saving when rotating the screw rod 360 through the knob 361.

[0038] In use, the discharge outlet of the discharging machine is connected with the lower hopper 100, and the conveying bag 200 and the circular pipe 320 are installed, and the bottom end of the conveying bag 200 is placed into the feeding port of the material barrel, and the screw rod 360 is rotated through the knob 361 to drive the sliding frame 370 to drive the rack 350 to move away from the knob 361 through the sliding rod 371, so as to drive a plurality of gears 340 to drive the corresponding mounting plates 330 to rotate clockwise, at this time, the gap between the adjacent two mounting plates 330 forms a discharge port, and the greater the rotation angle of the mounting plate 330 from the horizontal state to the vertical state, the greater the discharge port formed between the adjacent two mounting plates 330, and the staff stops rotating the screw rod 360 after rotating the mounting plate 330 to the appropriate angle according to the caliber of the material barrel, and after the above operation, the staff first threadedly connects the threaded rod 386 with the threaded hole 387, so as to fix the rack 350 and the moving rod 384 and the moving frame 383, and then releases the clamping of the clamping rod 373 and the fixing hole 372, and the medium is discharged into the fixed frame 310 through the lower hopper 100, and falls into the circular pipe 320 through the discharge port formed by the plurality of mounting plates 330 and enters the material barrel through the conveying bag 200, and during the discharging process, the first motor 381 is controlled to be started to drive the reciprocating screw rod 382 to rotate, so as to drive the moving frame 383 to reciprocate, at this time, the rack 350 is driven to reciprocate synchronously through the moving rod 384 under the action of the threaded rod 386 and the threaded hole 387, so as to drive the plurality of gears 340 to drive the corresponding mounting plates 330 to reciprocate, and the reciprocating angle is between fifteen degrees and twenty degrees, so that the medium entering the fixed frame 310 is better discharged through the discharge port.

[0039] The reciprocating screw rod 382 is in the form of two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw rod 382, the moving block placed in the spiral groove is pushed to make axial reciprocating motion. Therefore, when the reciprocating screw rod 382 rotates, the moving frame 383 moves reciprocally in the horizontal direction.

[0040] It should be noted that the motors and the like in the above description are relatively mature devices in the prior art, and the specific model can be selected according to actual needs. Meanwhile, the motor power supply can be an internal power supply or a mains power supply, and the specific power supply mode is selected as needed, which will not be described here.
