That is, referring to fig. 10, the first ball nut 332b is simultaneously hinged with the top of the first rod 331a1 of the fourth cross member 331a and the top of the second rod 331a2 of the fifth cross member 331a from left to right; the second ball nut 332c is hinged to both the bottom of the second rod 331a2 of the fourth cross member 331a and the bottom of the first rod 331a1 of the fifth cross member 331a from left to right.
Based on the above structure, when the first ball nut 332b and the second ball nut 332c move in opposite directions, the two ball nuts 332b and 332c drive all hinge points on the upper and lower sides of the cross type telescopic component 331 to approach to the middle, so that the cross type telescopic component 331 expands towards both sides in the horizontal direction, the distance between the fixing shafts 34 increases simultaneously, and finally, the liquid filling pipes 31 move horizontally along the rail 36 synchronously by means of the corresponding sliding blocks 35, so that the distance between the liquid filling pipes 31 increases synchronously. Similarly, when the first ball nut 332b and the second ball nut 332c move back to back, the two ball nuts 332b and 332c drive all hinge points on the upper side and the lower side of the cross type telescopic component 331 to move back to back, so that the cross type telescopic component 331 can be folded towards the middle in the horizontal direction, the distance between the fixing shafts 34 can be synchronously reduced, and finally, the liquid adding pipes 31 can synchronously move horizontally along the rail 36 by means of the corresponding sliding blocks 35, so that the distance between the liquid adding pipes 31 can be synchronously reduced.
Further, referring to fig. 2, 7 and 10, a connecting shaft 332d is connected to the top of the screw rod 332a, the connecting shaft 332d penetrates through the top surface 371 of the supporting frame 37 and is connected to the top surface 371 through a first bearing 332e, and a knob 332f is disposed on the top of the connecting shaft 332 d; meanwhile, a second bearing 332g is sleeved on the unthreaded section 332a3 in the middle of the screw rod 332a, and the second bearing 332g is fixed on the inner wall of the back side surface 374 of the supporting frame 37 through a mounting seat 332 h. In this structure, the two bearings 332e and 332g support the screw 332a, so that the screw 332a can rotate freely, and when the knob 332f is rotated by hand, the screw 332a rotates, and the first ball nut 332b and the second ball nut 332c move in the opposite direction or in the opposite direction, so that the distance between the liquid feeding pipes 31 can be adjusted.
Referring to fig. 2 and 9, a holder 381 is connected to one side of the fixed shaft 34, the filler pipe 31 is detachably mounted to the holder 381, and the other side of the fixed shaft 34 is connected to the slide block 35 through a mounting block 382.
With respect to the control assembly 39 described, and in particular with reference to fig. 3 and 11, the control assembly 39 includes a controller 391, a solenoid on/off button 392 and a liquid supply on/off button 393.
The number of the solenoid activation/deactivation buttons 392 is equal to the number of the solenoids 31a, and is eight, each solenoid activation/deactivation button 392 is connected to an input of the controller 391, and each solenoid activation/deactivation button 392 can transmit a signal to the controller 391 to determine activation or deactivation of the corresponding solenoid 31 a. The liquid supply on/off button 393 is connected to an input of the controller 391 for sending a signal to the controller 391 to control the opening and closing of the activated solenoid valve 31 a. Each of the solenoid valves 31a is connected to an output terminal of the controller 391.

Examples are: when the first to the fourth solenoid on/off buttons 392 are pressed, the front four solenoid valves 31a are activated, and the rear four solenoid valves 31a are still deactivated, so that when the user presses the liquid supply on/off button 393, only the front four solenoid valves 31a are opened, the rear four solenoid valves 31a are not changed in state and are still closed, and therefore, only the front four filling pipes 31 release the nutrient solution. It can be seen that the user can select which solenoid valves 31a need to be activated and which need to be deactivated according to the situation, for example, when there are eight breeding chambers 41 in each row of the breeding plate 4, all the solenoid valve activation/deactivation buttons 392 need to be pressed to activate the eight solenoid valves 31a at the same time, and when there are only six breeding chambers 41 in each row of the breeding plate 4, only the middle six solenoid valve activation/deactivation buttons 392 need to be pressed to activate the middle six solenoid valves 31 a.
