[0028] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1,

[0030] See also Figures 1 to 11 The present invention provides a technical solution: it includes a seedling tray fixing base frame 1, a seedling tray fixing assembly 2 is arranged above the seedling tray fixing base frame 1, a matching lower seedling assembly 3 is arranged at the front bottom of the seedling tray fixing base frame 1, the seedling tray fixing assembly 2 includes a fixed vertical frame 21 symmetrically fixedly installed on the front and rear sides of the seedling tray fixing base frame 1, and the fixed vertical frame 21 has seedling tray placement baffles 22 evenly distributed up and down inside. The matching lower seedling assembly 3 includes a lower seedling roller 33 and a pushing roller 34 respectively rotatably installed on the inner surface of the seedling tray fixing base frame 1, and the upper surface of the seedling tray placement baffle 22 is fixedly installed with a limiting strip 221, and the two ends of the seedling tray placement baffle 22 are respectively rotatably connected to the side walls of the fixed vertical frame 21. 2 is fixedly installed with a meshing toothed disc 222 on the outer surface of one end, and a transmission chain 23 adapted to the meshing toothed disc 222 is movably installed on the inner surface of the fixed vertical frame 21, and the inner surface of the transmission chain 23 is meshed with the outer surface of the meshing toothed disc 222. A motor 25 is fixedly installed below the outer surface of the seedling tray placement baffle 22, and a rotating shaft at one end of the meshing toothed disc 22 installed on the seedling tray placement baffle 22 passes through the side wall of the fixed vertical frame 21 and is fixedly connected to the output shaft of the motor 25. The bottom of the seedling tray fixed base frame 1 is fixed with an arc-shaped sliding bottom plate, and the front end outer surface of the seedling tray fixed base frame 1 is fixedly installed with an armrest fixed to the rice planter, and the bottom of the seedling tray guide plate 31 is fixedly installed with a toothed guide inclined plate;

[0031] In the present embodiment, the front end handrail of the seedling tray fixed chassis 1 is fixed to the rear end frame of the rice seeder to ensure that the position of the seedling tray guide plate 31 is located above the transmission shaft of the rice seeding gun of the rice seeding machine, so that the toothed guide inclined plate of the seedling tray fixed chassis 1 is adapted to the spacing of the transplanting gun, that is, the seedling tray guide plate 31 is used to replace the guide plate of the traditional rice seeder, and multiple groups of seedling tray placement baffles 22 are arranged on the upper end of the fixed vertical frame 21 to stack the group seedling trays 24 so that the seeder can carry more seedlings for mobile sowing, and the arc-shaped sliding bottom plate at the bottom of the seedling tray fixed chassis 1 is convenient for moving with the seeder in the rice field, and the seedling tray placement baffle 22 at the lowest end of the fixed vertical frame 21 is driven to rotate by the motor 25, and the transmission chain 23 is used to make The seedling tray placing baffle 22 on the fixed vertical frame 21 is rotated at the same time to make it flip over. It is worth noting that the motors 25 installed on the fixed vertical frames 21 on both sides above the seedling tray fixed base frame 1 rotate in opposite directions, so that the seedling trays 24 piled on the seedling tray placing baffle 22 fall to one position in turn, and cooperate with the seedling lowering component 3 to complete automatic unloading, instead of manual handling. The limiting strip 221 mainly limits the placement of the seedling tray 24, so that it can be positioned and placed neatly up and down, which solves the problem in the prior art that the seedling tray is easily damaged when the seedlings need to be manually moved to the rice sowing and transplanting machine, affecting the survival rate. The seedling tray can be improved so that it can automatically and neatly separate the seedlings and be used in conjunction with the rice sowing machine.

[0032] Embodiment 2:

[0033] See also Figures 1 to 5 On the basis of the first embodiment, in order to delay the falling time of the seedling tray 24 placed on the upper seedling tray placement baffle 22 to ensure that the lower seedling tray placement baffle 22 can be reset in time to receive the upper seedling tray 24, the present embodiment further proposes that an elastic arc pad is provided below the seedling tray placement baffle 22, the upper end of the elastic arc pad is hingedly mounted on the inner surface of the fixed vertical frame 21, and the lower end of the elastic arc pad is abutted against a reset spring rod;

[0034] In the present embodiment, after the seedling tray placing baffle 22 is driven by the transmission chain 23 and the motor 25 to flip over, the seedling tray 24 above the seedling tray placing baffle 22 will automatically fall down, at which time the elastic arc-shaped pad will be squeezed and deformed. Because the deformation and squeezing of the elastic arc-shaped pad will prolong the falling time of the seedling tray 24, the seedling tray placing baffle 22 of the lower layer has enough time to reset and receive the seedling tray 24, avoiding that multiple layers of seedling trays 24 fall together and stack together, ensuring that one group of seedling trays 24 are unloaded in sequence, and after the seedling tray 24 falls, the reset spring rod will rebound and push the elastic arc-shaped pad to reset, ensuring that the next squeezing will prolong the falling time of the seedling tray 24, solving the problem in the prior art that the seedling tray is easily damaged when the seedlings need to be manually moved to the rice sowing and transplanting machine, affecting the survival rate, and the seedling tray can be improved so that it can automatically and neatly separate the seedlings for use with the rice sowing machine.

[0035] Embodiment 3,

[0036] See also Figures 1 to 11 On the basis of the second embodiment, in order to realize that the seedling raising tray 24 can be rolled to separate the seedlings, the present embodiment further proposes that a seedling raising tray 24 is arranged above the baffle plate 22 for placing the seedling tray, the size of the limiting strip 221 is adapted to the size of the seedling raising tray 24, the upper surface of the seedling raising tray 24 is evenly distributed with honeycomb seedling raising grooves, the lower surface of the seedling raising tray 24 is evenly provided with water permeable holes, a bottom engaging pad 241 is fixedly installed on the lower surface of the front end of the seedling raising tray 24, a pushing strip 242 is fixedly installed on the middle part of the lower surface of the seedling raising tray 24, a seedling tray guide plate 31 is hingedly installed on the inner surface of the front end of the seedling tray fixing chassis 1, and a seedling separation inclined plate 311 is fixedly installed on the upper end of the seedling tray guide plate 31;

[0037] In this embodiment, the seedling tray 24 is made of PET material with high strength and toughness, can be rolled up, and can also be recycled. The water-permeable holes are located at the bottom of the honeycomb seedling trough, so that the seedlings can absorb water evenly and be evenly arranged. The bottom snap-fit ​​pad 241 is convenient for cooperating with the lower seedling roller 33 to make the seedling tray 24 be rolled up, and the pushing bar 242 cooperates with the pushing roller 34 to facilitate the displacement of the seedling tray 24. The seedling tray 24 falls from the bottom seedling tray placement baffle 22 and falls on the upper surface horizontal plate of the seedling tray fixed chassis 1. At this time, the lower seedling roller 33 and the pushing roller 34 are convenient for cooperating with each other to push the seedling tray 24 to move. The rollers 34 rotate in coordination to push the seedling tray 24 forward and reel it in, so that the rice seedlings on the seedling tray 24 are separated, scooped up by the seedling separation inclined plate 311 at the upper end of the seedling tray guide plate 31, and slide down the seedling tray guide plate 31, waiting for the seeding gun of the seeder to perform the seeding and sowing operation. This solves the problem in the prior art that the seedling tray is easily damaged and the survival rate is affected when the seedling tray needs to be manually moved to the rice sowing and transplanting machine. The seedling tray can be improved so that it can automatically and neatly separate the seedlings for use with the rice seeder.

[0038] Embodiment 4:

[0039] See also Figures 1 to 11 On the basis of the third embodiment, in order to realize the automatic winding and separation of the seedling raising tray 24, the present embodiment further proposes that a second motor 32 is fixedly installed on the outer surface of the front end of the seedling tray fixed chassis 1, a belt is movably installed between the outer surface of one end of the lower seedling roller 33 and the outer surface of one end of the pushing roller 34, a rotating shaft at one end of the lower seedling roller 33 passes through the side wall of the seedling tray fixed chassis 1 and is fixedly connected to the output shaft of the second motor 32, a rolling bending plate 331 is hingedly installed on the outer surface of the lower seedling roller 33, the size of the rolling bending plate 331 is adapted to the size of the bottom engaging pad 241, and a pushing rod 341 is fixedly installed on the outer surface of the pushing roller 34;

[0040] The motor 32 of the present embodiment drives the lower seedling roller 33 and the push roller 34 to rotate simultaneously through the cooperation of the belt. When the push roller 34 rotates, the push rod 341 on the outer surface thereof contacts the push bar 242 under the seedling raising plate 24 to push the seedling raising plate 24 to move forward. The seedling raising plate 24 is pushed and displaced, so that the bottom engaging pad 241 moves to the front end of the seedling raising plate fixed base frame 1. When the lower seedling roller 33 rotates counterclockwise, the rolling bending plate 331 will just fit into the bottom engaging pad 241. As the lower seedling roller 33 rotates, the seedling raising plate 24 is rolled up, and the seedling raising plate 2 The seedlings on the upper side are separated with the cooperation of the seedling separation inclined plate 311. When the seedling raising tray 24 is completely rolled under the lower seedling roller 33, the pushing roller 34 continues to rotate the pushing rod 341 to push the seedling raising tray 24 to make the bottom engaging pad 241 separate from the rolling bending plate 331, so as to complete the seedling separation and feeding of the seedling raising tray in sequence. This solves the problem in the prior art that the seedling raising tray is prone to damage to the seedlings and affects the survival rate when the seedling raising tray needs to be manually moved to the rice sowing and transplanting machine. The seedling raising tray can be improved so that it can automatically and neatly separate the seedlings and cooperate with the rice sowing machine for use.

[0041] Embodiment 5,

[0042] See also Figures 1 to 11 On the basis of the fourth embodiment, in order to realize that the rolling and bending plate 331 can be more conveniently inserted into and separated from the bottom clamping pad 241, the present embodiment further proposes that a swinging and squeezing plate is added inside the lower seedling roller 33, and the outer surface of the lower seedling roller 33 is provided with a swinging groove adapted to the swinging and squeezing plate, the upper end of the swinging and squeezing plate contacts the inner surface of the rolling and bending plate 331, and the other end of the swinging and squeezing plate is inserted with a sliding rod, one end of the sliding rod is fixedly mounted on the central axis of the lower seedling roller 33, and the outer surface of the sliding rod is sleeved with a spring sleeve, and the upper end of the spring sleeve contacts the inner surface of the swinging and squeezing plate.

[0043] When the lower seedling roller 33 rotates, due to the action of centrifugal force, the swinging extrusion plate will be swung out along the trajectory of the sliding rod to lift up the rolling and bending plate 331. When the seedling raising plate 24 is at the front end of the rolling and bending plate 331, the rolling and bending plate 331 is lifted up by the swinging and extrusion plate and is just inserted into the bottom locking pad 241. When the seedling raising plate 24 is located under the lower seedling roller 33, the rolling and bending plate 331 is lifted up by the swinging and extrusion plate, and the downward push of the seedling raising plate 24 by the pushing rod 341 just makes the rolling and bending plate 331 disengage from the bottom locking pad 241, making the winding of the seedling raising plate 24 more convenient, which solves the problem in the prior art that the seedling raising plate is easily damaged when the seedlings need to be manually moved to the rice sowing and transplanting machine, affecting the survival rate. The seedling raising plate can be improved so that it can automatically and neatly separate the seedlings and be used in conjunction with the rice sowing machine.

[0044] Embodiment 6,

[0045] See also Figures 1 to 11 Based on the fifth embodiment, this embodiment further provides a method for using a rice seedling tray that is easy to install for a rice planter, comprising the following steps:

[0046] Step 1: Use the rice seedling raising tray 24 to sow and raise rice seedlings, and place the rice seedling raising tray 24 on the rice seedling placing baffle 22;

[0047] Step 2: fix the front handrail of the seedling tray fixed chassis 1 to the rear end frame of the rice planter, ensure that the position of the seedling tray guide plate 31 is located above the transmission shaft of the rice transplanting gun of the rice planter, and make the toothed guide inclined plate of the seedling tray fixed chassis 1 and the spacing of the rice transplanting gun fit;

[0048] Step 3: The motor 1 25 drives the seedling tray placement baffle 22 at the bottom of the fixed vertical frame 21 to rotate, so that the seedling tray placement baffle 22 on the fixed vertical frame 21 rotates at the same time to flip it, so that the seedling trays 24 stacked on the seedling tray placement baffle 22 fall down one position in turn, and the seedling trays 24 fall from the bottom seedling tray placement baffle 22 and fall on the upper surface horizontal plate of the seedling tray fixed bottom frame 1;

[0049] The fourth step is to drive the motor 32 to drive the lower seedling roller 33 and the push roller 34 to rotate at the same time through the cooperation of the belt. When the push roller 34 rotates, the push rod 341 pushes the seedling tray 24 to move forward, so that the bottom engaging pad 241 moves to the front end of the seedling tray fixed frame 1, and when the lower seedling roller 33 rotates counterclockwise, the rolling bending plate 331 will just fit into the bottom engaging pad 241. As the lower seedling roller 33 rotates, the seedling tray 24 is rolled up, and the rice seedlings on the seedling tray 24 are separated, scooped up by the seeding inclined plate 311 at the upper end of the seedling tray guide plate 31, and slide down along the seeding tray guide plate 31, waiting for the seeding gun of the seeder to perform the seeding and sowing operation.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
