DETAILED DESCRIPTION

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Example 1

[0025] Reference Figure 1 As shown, an embodiment of the present application discloses a rice transplanting assembly, including: a rice seedling dropping component 1; a rice seedling dropping channel 11, which is opened in a straight line in the rice seedling dropping component 1, one end of which is for rice seedlings to be dropped into, and the other end of which extends toward the rice field; an air supply channel 12, which is opened in the rice seedling dropping component 1, one end of the air supply channel 12 is connected to the inner wall surface of the rice seedling dropping channel 11 as an air outlet, and the other end of the air supply channel 12 is used as an air inlet; a positive pressure source 13, which is connected to the air inlet of the air supply channel 12 and is used to provide positive pressure.

[0026] During the rice transplanting operation, the positive pressure source 13 is in working condition, and the positive pressure source 13 provides positive pressure blowing to the air supply channel 12; when the seedlings are above the air outlet, the positive pressure source 13 can blow air into the air supply channel 12, accelerate the air circulation speed below the seedlings, provide negative pressure to the seedlings, accelerate the falling of the seedlings, and prevent the seedlings from being blocked in the seedling falling channel 11; when the seedlings fall below the air outlet, the positive pressure source 13 can directly blow air to the seedlings to provide positive pressure, blow the seedlings down and insert them into the rice field, and complete the rice transplanting work.

[0027] In the present invention, the rice seedling transplanting action is completed pneumatically without mechanically clamping the rice seedlings, which can better protect the root system of the rice seedlings, prevent the rice seedlings from being damaged, and improve the transplanting quality.

[0028] It is worth mentioning that the seedlings can be put into the seedling dropping component 1 in bundles by the staff; of course, when the seedlings are raised on the tray, they can be raised in bundles to facilitate the later transplanting.

[0029] In this embodiment, the positive pressure source 13 may be an air compressor, which provides compressed air to the air supply channel 12 .

[0030] Preferably, the seedling dropping channel 11 is opened in the seedling dropping component 1 along the vertical direction, and the angle α between the central axis of the air supply channel 12 and the central axis of the seedling dropping channel 11 is 35°; selecting the preferred angle and using compressed air to impact the seedlings in an oblique pneumatic manner can further ensure the quality of transplanting.

[0031] Reference Figure 2 and Figure 4 As shown, the assembly also includes: a frame; a plurality of bearing rods 2, which are installed on the frame in parallel; a seedling storage plate 3, which is inclined at a fixed angle to the horizontal plane and can be slidably sleeved on the bearing rod 2 for placing a plurality of seedlings; a first seedling delivery channel 31, which is located below the seedlings in the vertical direction and is arranged on the seedling storage plate 3, with one end facing the seedlings and the other end extending toward the seedling dropping component 1; a seedling separation component 4, which is located below the first seedling delivery channel 31 in the vertical direction and can be slidably arranged on the seedling storage plate 3; a seedling storage trough 41, which is opened on the seedling separation component 4 and is used to store Receive seedlings; the second seedling delivery channel 32 is located below the seedling separation component 4 in the vertical direction, with one end facing the seedling separation component 4 and the other end facing the seedling dropping component 1; the first telescopic component 51 is arranged on the frame, and the piston rod of the first telescopic component 51 is connected to the seedling storage plate 3, which is used to drive the seedling storage plate 3 to swing back and forth along the axial direction of the bearing rod 2; the second telescopic component 52 is arranged on the seedling storage plate 3, and the piston rod of the second telescopic component 52 is connected to the seedling separation component 4, which is used to drive the seedling storage trough 41 to alternately connect the first seedling delivery channel 31 and the second seedling delivery channel 32.

[0032] In this embodiment, the first telescopic component 51 is installed below the seedling storage board 3 parallel to the bearing rod 2 , and the main body of the first telescopic component 51 is arranged on the frame; the main body of the second telescopic component 52 is arranged on the seedling storage board 3 .

[0033] During the rice transplanting work, a number of rice seedlings are stored on the surface of the rice seedling storage board 3. The piston rod of the first telescopic component 51 makes reciprocating motion, which can drive the rice seedling storage board 3 to make linear reciprocating swings, and can cause relative displacement between the first rice seedling delivery channel 31 and the rice seedlings, preventing the rice seedlings from being blocked outside the first rice seedling delivery channel 31.

[0034] Under the action of gravity, the seedlings pass through the first seedling delivery channel 31 one by one and enter the seedling storage trough 41; the second telescopic component 52 contracts to drive the seedling storage trough 41 to move and connect the seedling storage trough 41 to the second seedling delivery channel 32; under the action of gravity, the seedlings in the seedling storage trough 41 pass through the second seedling delivery channel 32 and are dropped into the seedling dropping component 1.

[0035] It is worth mentioning that the reciprocating motion of the piston rod of the first telescopic component 51 can drive the seedling storage plate 3 to make a linear reciprocating swing, which can cause a relative displacement between the second seedling delivery channel 32 and the seedlings, preventing the seedlings from being retained in the seedling storage tank 41.

[0036] By using the present invention, the seedlings can be periodically dropped into the seedling dropping component 1 one by one, which can reduce the manual labor and further improve the automation of the rice transplanting action. In addition, the seedlings are not clamped during the entire seedling separation work, which can effectively prevent the seedlings from being damaged.

[0037] Reference Figure 5 As shown, five seedling storage grooves 41 are arranged in an array at a fixed distance on the seedling separation component 4, and five first seedling delivery channels 31 and five second seedling delivery channels 32 are arranged in an array at a fixed distance on the seedling storage plate 3.

[0038] It is worth mentioning that five seedling dropping components 1 are correspondingly arranged below the five second seedling delivering channels 32. By setting up five seedling dropping channels 11, the transplanting operation of five seedlings in a row can be completed synchronously; of course, according to the specifications of the rice field and the planting requirements, the number of seedling dropping components 1 and the distance between two adjacent seedling dropping components 1 should be flexibly changed.

[0039] It is worth mentioning that a guide block 6 is arranged between two adjacent first seedling conveying channels 31 ; a guide slope is arranged on the guide block 6 for guiding the seedlings toward the first seedling conveying channel 31 ; the seedlings are guided to move toward the first seedling conveying channel 31 to prevent the seedlings from being blocked between the two adjacent first seedling conveying channels 31 .

[0040] Reference Figure 2 As shown, the component also includes: a buffer component 71, which is arranged on the frame and is located between the second seedling delivery channel 32 and the seedling falling component 1 in the vertical direction; a seedling storage hole 72, which is arranged in the buffer component 71 and is used to receive the seedlings; a mounting shaft 73, which is arranged on the buffer component 71; a bearing component 74, which is rotatably arranged on the mounting shaft 73, is located below the seedling storage hole 72, and is used to bear the seedlings; a plurality of torsion springs 75, which are sleeved on the mounting shaft 73, one end of which abuts the buffer component 71 and the other end of which abuts the bearing component 74; a pushing component 76 and a third telescopic component 53, the third telescopic component 53 is arranged on the frame, the pushing component 76 is arranged on the piston rod of the third telescopic component 53, the piston rod of the third telescopic component 53 makes an extension movement, and can drive the pushing component 76 to resist the bearing component 74 and rotate around the mounting shaft 73.

[0041] During specific operation, the seedlings output by the second seedling delivery channel 32 fall into the seedling storage hole 72, and the seedling storage hole 72 receives the seedlings for buffering. When the seedling dropping component 1 moves to the specified position, the third telescopic component 53 is started, and the piston rod of the third telescopic component 53 moves to the east, driving the pushing component 76 to push the bearing component 74, and the bearing component 74 rotates around the mounting shaft 73 to empty the bottom of the seedling storage hole 72. Under the action of gravity, the seedlings are dropped into the seedling dropping component 1; by setting the buffer component 71, the seedlings can be buffered by plant division, and the transplanting work of the seedling dropping component 1 and the transplanting work on the seedling storage plate 3 can be carried out simultaneously, thereby improving the transplanting efficiency.

[0042] Specifically, two bearing components 74 are symmetrically arranged on the bearing component 74, and are also symmetrically arranged on both sides of the seedling storage hole 72 through two installation shafts 73. When the pushing component 76 synchronously pushes the two bearing components 74 to rotate around the two installation shafts 73 respectively, a V-shaped groove can be formed below the seedling storage hole 72, which can guide the seedlings to fall toward the seedling dropping component 1, thereby ensuring the smooth delivery of the seedlings.

[0043] Preferably, two third telescopic components 53 are symmetrically arranged at both ends of the buffer component 71 . The third telescopic components 53 are vertically installed, and a through hole for the pushing component 76 to pass through is opened on the buffer component 71 .

[0044] Preferably, the assembly further comprises: a ball 77 which is rollably mounted on one end of the pushing member 76 and is used to abut against the bearing member 74 . The ball 77 rolls in contact with the bearing member 74 to reduce wear.

[0045] In this embodiment, the first telescopic component 51 , the second telescopic component 52 and the third telescopic component 53 may all be electric push rods.

[0046] Reference Figure 6 As shown, in the specific installation, a plurality of torsion springs 75 are sleeved on the installation shaft 73, one end of the torsion spring 75 is located below the bearing component 74, for supporting the bearing component 74; the other end of the torsion spring 75 is located above the bearing component 74, for abutting the buffer component 71; when the piston rod of the third telescopic component 53 extends, it can push the bearing component 74 to rotate and squeeze and deform the torsion spring 75; when the piston rod of the third telescopic component 53 contracts, the torsion spring 75 recovers its deformation, which can drive the bearing component 74 to return to its original position, thereby blocking the seedling storage hole 72.
