[0026] The application discloses an automatic fertilizer adding device for a floating seedling pool of flue-cured tobacco, which comprises a rack assembly, a spraying assembly, and a moving assembly.

[0027] The sliding rail is relatively long relative to the seedling pool, so that the automatic fertilizer adding device for the floating seedling pool of flue-cured tobacco is relatively small in size; the support is arranged on both sides of the seedling pool, and the sliding rail is horizontally arranged above the seedling pool; the translation mechanism drives the sliding block to move along the sliding rail, the water pump delivers the liquid fertilizer in the liquid storage member to the spray head through the conveying pipe, and the spray head is arranged on the sliding block, so that the spray head can fertilize the tobacco seedlings in the seedling pool; when the spray head moves along the sliding rail, the conveying pipe moves along with the spray head; since the conveying pipe is a flexible pipe, the conveying pipe can move flexibly; the sliding rail is formed by splicing a plurality of rails through the structure of the clamping block and the clamping groove; the sliding rail can be disassembled into a plurality of rails when not in use, so as to be conveniently stored; the two rails can be clamped or disengaged by moving along the width direction of the rail; when the sliding rail is horizontally arranged above the seedling pool, the gravity of the rail drives the clamping block to press the side wall of the clamping groove downward; since the slot direction of the clamping groove extends along the width direction of the rail, the clamping groove can limit the movement of the clamping block in the height direction of the rail, so that the rail cannot fall under the action of gravity.

[0028] In one embodiment, the translation mechanism comprises a belt 3021, a translation motor 3022, and two belt pulleys 3023; the two belt pulleys 3023 are rotationally connected with the sliding rail; the belt 3021 is sleeved on the two belt pulleys 3023; the translation motor 3022 is arranged on the sliding rail and is in transmission connection with one of the belt pulleys 3023; one end of the sliding block 301 is connected with the belt 3021.

[0029] The slider 301 is in sliding connection with the slide rail. The translation motor 3022 drives one of the pulleys 3023 to rotate. The belt 3021 rotates with the pulley 3023. The belt 3021 drives the slider 301 to move along the slide rail, so that the nozzle 201 moves along the slide rail.

[0030] One end of the slider 301 is connected with the belt 3021. The other end of the slider 301 is provided with a guide hole 3011 for the belt 3021 to pass through. If the slider 301 is not provided with the guide hole 3011, the slider 301 will be in contact with the inner side wall of the belt 3021, causing the slider 301 and the belt 3021 to be worn. The slider 301 may shake left and right when moving. Therefore, the guide hole 3011 limits the belt 3021 and makes the slider 301 more stable when moving.

[0031] In one of the embodiments, the slide rail is provided with a mounting cavity matched with the slider 301 and a placement hole 1013 communicated with the mounting cavity. The placement hole 1013 is rectangular and the long side is parallel to the length direction of the slide rail.

The conveying pipe 202 passes through the placement hole 1013 and is communicated with the conveying hole.

[0032] Each track 101 is internally provided with a groove. The grooves of the plurality of tracks 101 are combined to form a mounting cavity. The mounting cavity is a cuboid shape. The slider 301 is matched with the mounting cavity. The mounting cavity has a guiding and limiting effect on the slider 301. When the slider 301 moves along the slide rail, the placement hole 1013 limits the conveying pipe 202, preventing the conveying pipe 202 from swinging and causing the center of gravity of the slide rail to be unstable.

[0033] The placement hole 1013 can be located in the middle of the upper end of the slide rail. At this time, the slider 301 has a certain supporting effect on the conveying pipe 202. It should be noted that the "upper" here refers to the upper side in the Figure 1

[0034] The slide rail is provided with a through hole below, so that the nozzle 201 passes through the through hole and is connected with the slider 301.

[0035] In one of the embodiments, the moving assembly further comprises a cover plate 303, a hollow shaft motor 304 and a mounting cylinder 305. The hollow shaft motor 304 is fixed on the slider 301. One end of the mounting cylinder 305 passes through the conveying hole and is in transmission connection with the hollow shaft motor 304. The other end of the mounting cylinder 305 is detachably connected with the nozzle 201. The mounting cylinder 305 is hollow inside. The cover plate 303 is fixed on the hollow shaft motor 304. The cover plate 303 is provided with a connecting cylinder 308. One end of the connecting cylinder 308 is communicated with the conveying pipe 202. The other end of the connecting cylinder 308 is sleeved on the inside of the mounting cylinder 305 and is in rotary connection with the mounting cylinder 305.

[0036] ​The mounting cylinder 305 is rotationally connected with the sliding block 301, and the hollow shaft motor 304 drives the spray head 201 to rotate through the mounting cylinder 305, so that the spray head 201 can spray fertilizer to the surrounding seedlings. The conveying pipe 202 can be sleeved outside the connecting cylinder 308 and fixedly connected with the connecting cylinder 308. When the mounting cylinder 305 rotates, the connecting cylinder 308 and the conveying pipe 202 do not rotate relative to the sliding block 301.

[0037] In one of the embodiments, the moving assembly further comprises an elastic expansion piece and a sleeve 307; the sleeve 307 is fixedly connected to the inside of the mounting cylinder 305; the mounting cylinder 305 is provided with a first mounting hole 3051 extending radially along the mounting cylinder 305; the spray head 201 is provided with a second mounting hole 2011 and a mounting groove in communication with each other, the mounting groove is matched with the mounting cylinder 305, and the second mounting hole 2011 corresponds to the first mounting hole 3051; the elastic expansion piece is located in the first mounting hole 3051, one end of the elastic expansion piece is connected with the sleeve 307, and the other end of the elastic expansion piece extends out of the first mounting hole 3051 and extends into the second mounting hole 2011.

[0038] The spray head 201 is detachably connected with the mounting cylinder 305. After the spray head 201 finishes spraying fertilizer to the seedlings, the spray head 201 can be detached from the mounting cylinder 305, and then the spray head 201 can be disinfected to avoid cross infection.

[0039] When the spray head 201 is mounted on the mounting cylinder 305, a tool is used to press the elastic expansion piece, such as a screwdriver, a branch or a rod-shaped object, so that the elastic expansion piece is completely located in the first mounting hole 3051, and then the spray head 201 is sleeved outside the mounting cylinder 305. At this time, the mounting cylinder 305 is located in the mounting groove, and the spray head 201 is moved to the side of the conveying pipe 202. When the end of the spray head 201 close to the conveying pipe 202 moves to the second mounting hole 2011, the side wall of the mounting groove can continue to press the elastic expansion piece to make it located in the second mounting hole 2011, and the spray head 201 is continuously moved until the first mounting hole 3051 is aligned with the second mounting hole 2011. At this time, the elastic expansion piece restores to the original length and extends into the second mounting hole 2011, so that the spray head 201 is clamped on the mounting cylinder 305.

[0040] When the spray head 201 is detached from the mounting cylinder 305, an elongated tool is used to press the elastic expansion piece through the second mounting hole 2011. The diameter of the elongated tool is smaller than the diameter of the second mounting hole 2011, and at the same time, the spray head 201 is moved away from the mounting cylinder 305. After the elastic expansion piece abuts against the side wall of the mounting groove, the elongated tool is taken out, and then the spray head 201 can be detached from the mounting cylinder 305.

[0041] In one of the embodiments, the elastic extension piece comprises a locking block 3061 and a spring 3063; the first mounting hole 3051 comprises a first hole and a second hole, the first hole is close to the sleeve 307 and has a larger diameter than the second hole; the locking block 3061 is matched with the second hole, the locking block 3061 is provided with a limiting block 3062 matched with the first hole; one end of the spring 3063 is connected with the limiting block 3062, and the other end of the spring 3063 is connected with the sleeve 307.

[0042] The mounting cylinder 305 and the sleeve 307 can be made of metal materials, the locking block 3061 is placed in the second hole and the spring 3063 is placed in the first hole before the sleeve 307 is mounted on the mounting cylinder 305, then the sleeve 307 is sleeved in the inner hole of the mounting cylinder 305, and the sleeve 307 and the mounting cylinder 305 can be fixed by welding. The connecting part of the first hole and the second hole limits the limiting block 3062, so that the locking block 3061 cannot slide out of the second hole. The end of the locking block 3061 away from the limiting block 3062 can be hemispherical.

[0043] In one of the embodiments, the outer side wall of the connecting cylinder 308 is provided with a plurality of arc-shaped blocks 3081, and the inner side wall of the mounting cylinder 305 is provided with ring grooves matched with the arc-shaped blocks 3081. The cooperation of the arc-shaped blocks 3081 and the ring grooves enables the mounting cylinder 305 to rotate relative to the connecting cylinder 308, so that the mounting cylinder 305 and the connecting cylinder 308 can be axially limited to each other.

[0044] In one of the embodiments, the spray head 201 is provided with a plurality of nozzles 2012 arranged along an arc.
