[0047] The present invention provides a novel seed printing and sowing device, comprising an equipment frame 1, a film rolling machine for fixing a film roll and conveying a film 8 forward, a glue dispensing machine 6 for dispensing glue on the film 8 to form a glue array of a set shape on the film 8, a seed sowing bin 7 for sowing seeds so that the seeds adhere to each glue dispensing point in the glue array, a film pulling machine for pulling the film 8 forward and rewinding the film with seeds adhered thereto, a seed recovery bin 10 for collecting seeds that are not firmly adhered during the process of the film pulling machine rewinding the film, and a controller 27.

[0048] The equipment frame 1 is used to support and fix the film rolling machine, the glue dispensing machine 6, the seed sowing bin 7, the film pulling machine, the seed recovery bin 10 and the controller 27.

[0049] The bottom of the equipment rack 1 is provided with a plurality of pairs of running wheels 2 and legs 3. The running wheels 2 are foldable rollers, and the legs 3 are legs with shock absorption function and adjustable length to adapt to various terrains. Installing the running wheels 2 at the bottom of the equipment rack 1 can facilitate the transportation of the entire device. The top surface of the equipment rack 1 is a stepped surface, and the top plate of the front part is higher than the top plate of the rear part.

[0051] The film roll body 4 includes film roll mounting plates 28 fixed on the left and right sides of the lower rear side of the equipment frame 1, a film roll bracket 29 fixed on one of the film roll mounting plates 28, and a film roll roller 16 arranged between the left and right film roll mounting plates 28. A film roll motor 30 is installed on the film roll bracket 29, and the output shaft of the film roll motor 30 is connected to the film roll roller 16, and the film roll motor 30 is electrically connected to the controller 27.

[0052] The film roll transmission assembly 5 includes a film roll fixing plate 14 fixed on both sides of the equipment frame 1, and a guide roller 11, a power roller 12 and a driven roller 13 are arranged between the left and right film roll fixing plates 14. The guide roller 11 and the power roller 12 are arranged in parallel on the same plane and the guide roller 11 is arranged at the rear side of the power roller 12. The driven roller 13 is arranged below the power roller 12. The power roller 12 is connected to the film roll roller 16 through a roller shaft transmission mechanism. Preferably, the driven roller 13 is located between the guide roller 11 and the power roller 12 and close to the power roller 12.

[0053] The film 8 of the film roll fixed on the film winding roller 16 passes around the guide roller 11 from the rear side, and after being horizontally guided by the guide roller 11, passes around the power roller 12 from the front side of the power roller 12, and then is laid downward and passes around the driven roller 13 from the rear side and then enters the glue dispensing machine 6, and then passes under the glue dispensing wheel of the glue dispensing machine 6 and under the sowing port of the seed sowing bin 7, passes around the film drawing winding roller 17 and is then wound around the film drawing body 9 for winding.

[0054] The glue dispensing machine 6 includes a glue dispensing machine housing 18 fixed on the top of the equipment frame 1, a glue dispensing motor 26 arranged on the top of the glue dispensing machine housing 18, a first rotating shaft 25 connected to the output end of the glue dispensing motor 26, a transmission wheel 24 arranged at both ends of the rotating shaft 25, and a rotating shaft 19 whose two ends are connected to the transmission wheels 24 at corresponding positions through a glue dispensing transmission mechanism (not shown in the figure), a plurality of sliding connection blocks 21 are fixed on the rotating shaft 19, a connecting shaft 20 is arranged on one side of the rotating shaft 19, and glue dispensing wheels 22 corresponding to the number of sliding connection blocks 21 are arranged on the connecting shaft 20, the wheel rod 23 of the glue dispensing wheel 22 is fixed to the sliding connection block 21, and a glue dispensing head is arranged on the wheel rod 23 of each glue dispensing wheel 22, and the glue outlet of the glue dispensing head is in contact with the wheel surface of the glue dispensing wheel 22, and the glue dispensing head and the glue dispensing motor 26 are both electrically connected to the controller 27.

[0055] In this embodiment, the rotating shaft 19 is provided with two upper and lower shafts, and the connection shaft 20 is provided at a higher height than the rotating shaft 19 located at the lower side.

[0056] When the dispensing motor 26 is started, the dispensing motor 26 drives the first rotating shaft 25 to rotate, and the first rotating shaft 25 drives the rotating shaft 19 to rotate through the dispensing transmission mechanism. When the rotating shaft 19 rotates, the rotating shaft 19 drives the sliding connection block 21 to rotate synchronously. Since the sliding connection block 21 and the dispensing wheel 22 are fixed as a whole, the sliding connection block 21 can drive the dispensing wheel 22 to rotate synchronously when it rotates (that is, the dispensing wheel can be flipped up and down to realize the dispensing action). The dispensing wheel 22 flips up and down while cooperating with the forward movement of the film 8, and a glue array of a set shape can be formed on the film 8.

[0057] Since the dispensing wheel 22 has a needle tip on its wheel surface, when the dispensing wheel 22 turns downward to contact the film surface, the needle tip on its wheel surface will pierce the film surface. At this time, the dispensing head will discharge glue and glue can be attached to the edge of the hole in the film to form a glue hole.

[0058] When the film 8 with glue moves to the direction of the seed sowing bin 7, the seeds in the seed storage hopper 15 of the seed sowing bin 7 fall from the seed dropping port at the bottom thereof to the film 8. Some seeds will fall directly on the film surface, but some seeds will fall into the glue holes and be stuck by the glue at the edge of the glue holes. The film 8 with seeds continues to move forward.

[0059] When dispensing is required, the dispensing wheel 22 is lowered and placed on the dispensing position so that it can contact the film. When dispensing is not required, the dispensing wheel 22 is flipped up. The flipped dispensing wheel 22 can be placed on the rotating shaft 19 located above. The seed sowing density can be adjusted by adjusting the number of dispensing wheels located at the dispensing position and the interval time between flipping up and down of the dispensing wheels.

[0060] The seed sowing bin 7 comprises a seed storage hopper 15, which is an open hopper, and a straight-open seed dropping opening is provided at the bottom of the seed storage hopper 15.

[0061] The film drawing machine includes a film drawing winding roller 17 arranged at the front side of the equipment frame 1 and located in front of the seed sowing bin 7, and a film drawing body 9 arranged at the lower front side of the equipment frame 1, and a seed recovery bin 10 is arranged below the film drawing body 9.

[0062] The film-drawing winding roller 17 is arranged at a height flush with the higher part of the top surface of the equipment frame 1 .

[0063] The film-stretching body 9 includes a film-stretching fixing frame 30 fixed on both sides of the equipment frame 1, a film-stretching roller 32 arranged between the left and right film-stretching fixing frames 30, a film-stretching fixing plate 31 fixed on one of the film-stretching fixing frames 30, and a film-stretching motor 33 fixed on the film-stretching fixing plate 31, the output end of the film-stretching motor 33 is connected to the film-stretching roller 32, and the film-stretching motor 33 is electrically connected to the controller 27.

[0064] After the film 8 with seeds adhered to it passes around the film-drawing and winding roller 17, it is wound downwardly around the film-drawing roller 32. As the film-drawing roller 32 rotates, the film 8 with seeds adhered to it is rolled up on the film-drawing roller 32 to achieve the winding of the film 8. During the winding process of the film 8, seeds that are not firmly adhered or do not fall on the glued position will fall into the seed recovery bin 10, thereby achieving seed recovery and avoiding seed waste. The recovered seeds can be reused.

[0065] In this embodiment, the film 8 is a fully biodegradable PBAT ground film with a thickness of 8-10 μm.

[0066] Preferably, the film-drawing fixing frame 30 is also fixed with a brake device 34 for controlling the rotation speed of the film-drawing roller 32 to control the film-rolling speed and prevent the film from being broken.

[0067] The present invention also provides a method for sowing using the device, which specifically comprises the following steps:

[0068] S1, setting the seed sowing density, sowing position and sowing shape in the controller 27;

[0069] S2, the film outlet end of the film roll is led out from the film roll roller 16, bypasses the film roll transmission assembly 5 and enters the glue dispenser 6, then passes under the glue dispenser wheel of the glue dispenser 6 and under the sowing port of the seed sowing bin 7, bypasses the film drawing and winding roller 17 and then is wound onto the film drawing roller 32;

[0070] S3, according to the set sowing position and sowing shape, the corresponding dispensing wheel 22 is rotated to the dispensing position;

[0071] S4, the film drawing machine, the film rolling machine and the glue dispensing machine 6 are started at the same time, and while the film 8 is conveyed forward by the film rolling machine and the film drawing machine, the glue dispensing wheel of the glue dispensing machine 6 is driven by its glue dispensing transmission mechanism to rotate up and down so that the needle tip on the wheel surface pierces the film 8 and glue is adhered to the edge of the hole to form glue holes while piercing the film 8, and a glue hole array is formed on the film 8 as the film 8 is conveyed forward;

[0072] When the film 8 with glue is transferred to the bottom of the seed sowing bin 7, the seeds are scattered on the film 8 from the seed dropping opening at the bottom of the seed sowing bin 7 and are glued to the glue holes through the glue at the edges of the glue holes. The film with seeds continues to be transferred forward and then rolled onto the film-drawing roller 32.

[0073] During the film being rolled up, the seeds that are not firmly adhered or not stuck fall into the seed recovery bin 10 for recovery;

[0074] S5, removing the rolled film with seeds from the film-drawing roller 32 and waiting for sowing;

[0075] S6. When planting seeds, spread the rolled film with seeds on the soil surface with the film facing up and the seeds facing down. The seeds are in contact with the soil and a thin layer of soil is covered on the film. Then water the seeds according to their growth needs. Based on the phototropism of the seedlings, the seed seedlings will drill out of the film through the holes in the glue.

[0076] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on 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.
