Description

Technical Field

[0001] This invention relates to the field of plug seedling technology, and in particular to a plug seedling sowing device. Background Technology

[0002] Sowing in seed trays is a crucial step in seedling cultivation, and the performance of the seedling sower directly impacts the quality of the seedlings produced. Mechanized vegetable seedling production offers numerous advantages: mechanically raised seedlings have a survival rate more than 20% higher than those raised using traditional methods. Compared to traditional manual seedling cultivation, seedling sowing in seed trays saves seeds, reduces costs, improves crop quality, and increases yield.

[0003] The sowing methods for tray seedling cultivation include manual sowing and mechanical sowing. Manual sowing is slow, labor-intensive, and inefficient. Mechanical sowing can overcome the disadvantages of manual sowing, but existing mechanical seeders have large investments, high costs, and complex structures, making it difficult to promote their widespread use. Moreover, neither manual nor mechanical sowing can accurately guarantee uniform sowing in each hole, and the actual operation does not achieve the expected results. Summary of the Invention

[0004] This invention discloses a seedling tray sowing device, which aims to solve the technical problems of slow manual sowing, high labor intensity and low efficiency, and large investment, high cost and complex structure of mechanical sowing machines, which are difficult to promote and use. In addition, neither manual sowing nor mechanical sowing can accurately guarantee uniform sowing in each hole.

[0006] A seed tray seedling sowing device includes a seeding machine and a control panel. A guide frame is fixedly connected to the top outer wall of the seeding machine. A seed storage hopper is movably arranged inside the guide frame. The bottom surface of the seed storage hopper has several arrayed seeding openings. A seeding tube is fixedly connected to the bottom surface of each seeding opening. A rapid sowing component is arranged inside the seeding machine and the seed storage hopper. The rapid sowing component includes a vibration motor, which is fixedly installed on the bottom surface of the seed storage hopper. A soil storage box is fixedly connected to the side wall of the seeding machine. Rollers are fixedly installed at the bottom of both the seeding machine and the soil storage box. A handrail is fixedly installed at the end of the soil storage box away from the seeding machine. The control panel is fixedly installed on the handrail. A soil leveling component is arranged on the bottom surface of the soil storage box.

[0007] The device is equipped with a seeding box, guide frame, seed storage hopper, seeding inlet, seeding tube, rapid sowing component, soil storage box, rollers, handrail, control panel, and soil leveling component. Seeds in the seed storage hopper are discharged through the seeding inlet into the seeding tube. The rapid sowing component evenly distributes the seeds into a row of holes on the seed tray, quickly sowing them into the holes. The seedling soil in the soil storage box is discharged through multiple outlet tubes and falls onto the seeds. The soil leveling component evenly distributes the seedling soil, achieving uniform filling and completing the sowing process. The seeds are precisely placed into multiple holes on the seed tray. The sowing speed is fast, the efficiency is high, and the labor intensity is low. The device has a simple structure, low cost, and is suitable for widespread use.

[0008] In a preferred embodiment, a fixed seat is fixedly connected to the middle of both sides of the bottom surface of the seed storage hopper. A movable rod is fixedly connected to the bottom surface of the fixed seat. A guide seat is fixedly connected to the top surface of the seed lowering machine box. Positioning holes are opened inside the guide seat and on the top surface of the seed lowering machine box. The movable rod is slidably disposed in the positioning hole.

A mounting bracket is fixedly connected to the outer wall of the seeding machine housing. A drive motor is fixedly mounted on the outer wall of the mounting bracket near the seeding machine housing. The power output shaft of the drive motor is connected to a drive wheel via a coupling. A driven wheel is rotatably mounted on the outer wall of the seeding machine housing. The same synchronous belt is slidably mounted on the surfaces of the drive wheel and the driven wheel. Multiple seeding discs are rotatably arranged in an array inside the seeding machine housing. The multiple seeding discs are fixedly connected together, with the outermost seeding disc fixedly connected to the outer wall of the driven wheel. Each seeding disc has several limiting holes arranged in a circular array on its outer wall. The seeding tube and the seeding disc are arranged vertically in correspondence.

[0009] Equipped with a rapid seeding component, the vibrating motor causes the seed hopper to vibrate inside the guide frame, allowing the seeds to be discharged smoothly through the seed outlet. The seeds fall evenly into multiple limiting slots. The drive motor is then activated to continuously feed the seeds into the multiple limiting slots, sowing them into a row of holes at once. The handrail is pushed to move the entire device until sowing of multiple rows of holes is completed, saving time and effort and achieving high sowing efficiency.

[0010] In a preferred embodiment, the top surface of the soil storage box is provided with a soil filling port, and a sealing cover is rotatably installed inside the soil filling port. Multiple soil discharge pipes corresponding to the seeding pipe are fixedly connected to the bottom surface of the soil storage box. A control valve is installed on the soil discharge pipe, and the soil leveling component is located on the side of the soil discharge pipe away from the seeding machine box.

[0011] The system is equipped with a soil storage box and a soil discharge pipe. After sowing in a row of seed trays, the soil discharge pipe moves above the seed trays and opens the control valve. The seedling soil in the soil storage box is discharged through the soil discharge pipe and falls into the seed trays, thus covering the seed trays with soil after sowing.

[0012] In a preferred embodiment, the soil leveling component includes a second mounting frame, which is fixedly connected to the bottom surface of the soil storage box. A second drive motor is fixedly mounted on the middle of the top surface of the second mounting frame.

A sliding frame is located below the rotating plate, and the eccentric sliding rod is slidably mounted inside the sliding frame. A fixed rod is fixedly connected to one end of the sliding frame, and a rack is fixedly connected to the bottom surface of the fixed rod. The top surface of the second mounting frame... A gear is rotatably mounted in the middle, and rack one meshes with the gear. Rack two meshes with the surface of the gear. Rack one and rack two are arranged in a circumferential array around the gear. Rack slides are fixedly connected to the bottom surfaces of rack one and rack two. Guide rails are fixedly connected to both ends of the top surface of mounting frame two. The rack slides are slidably mounted inside the guide rails. Sliding grooves are opened in the interior of mounting frame two and the bottom surface of guide rails. A connecting rod is fixedly connected to the bottom surface of the rack slides. The connecting rod is slidably mounted in the sliding groove. A fixing plate is fixedly connected to the bottom surface of the connecting rod. A soil combing rake claw is fixedly mounted on the bottom surface of the fixing plate.

[0013] With the soil leveling component in place, after the holes are covered with soil, the drive motor is activated to make the soil rake claws reciprocate, which sorts the seedling soil on the seed tray, ensuring that the holes are evenly covered with soil, thus improving the seed survival rate.

[0014] As can be seen from the above, the seedling tray sowing device provided by the present invention has the technical effect of accurately sowing seeds into multiple holes on the seed tray, quickly sowing seeds into multiple holes on the seed tray, fast sowing speed, high efficiency, low labor intensity, simple structure, low cost, and suitable for widespread use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] The seedling tray sowing device disclosed in this invention is mainly used in scenarios where manual sowing is slow, labor-intensive, and inefficient, while mechanical sowing machines are expensive, costly, and complex in structure, making them difficult to widely promote and use. Furthermore, neither manual nor mechanical sowing can accurately guarantee uniform sowing in each hole.

[0025] Reference Figures 1-7 A seed tray seedling sowing device includes a seeding machine box 1 and a control panel 10.

After sowing, the control valve on the soil outlet pipe 11 is opened, and the seedling soil in the soil storage box 7 is discharged through multiple soil outlet pipes 11 and falls onto the seeds. The soil leveling component 12 evenly combs the seedling soil to achieve uniform filling of the seedling soil, completing the sowing. The seeds are accurately placed into multiple holes on the seed tray. The sowing speed is fast, the efficiency is high, the labor intensity is low, the device has a simple structure, low cost, and is suitable for widespread use.

Positioning holes are opened in the interior of the guide seat 604 and the top surface of the seed lowering machine box 1. The movable rod 603 is slidably disposed in the positioning hole. A spring 605 is sleeved on the surface of the movable rod 603. The top end of the spring 605 is fixedly connected to the bottom surface of the fixed base 602, and the bottom end of the spring 605 is fixedly connected to the top of the guide seat 604. The inner rotating frame 606 is fixedly connected to both outer walls of the fixed base 602, and the outer rotating frame 607 is fixedly connected to both inner walls of the top of the seeder housing 1. Rotary joints 608 are rotatably provided on the surfaces of both the inner and outer rotating frames 606 and 607. A piston rod 609 is fixedly connected to the outer wall of the outer rotating frame 607 connected to the inner rotating frame 606. An outer sleeve 610 is provided between the inner rotating frame 606 and the outer rotating frame 607. The piston rod 609 is slidably disposed inside the outer sleeve 610. The outer wall of the rotary joint 608 connected to the outer rotating frame 607 is fixed. A sealing disc 611 is fixedly connected to the outer wall of the outer sleeve 610. A second spring 612 is fitted onto the surface of the piston rod 609, with one end fixedly connected to the outer wall of the sealing disc 611 and the other end fixedly connected to the inner wall of the outer sleeve 610. A mounting bracket 613 is fixedly connected to the outer wall of the lower seed housing 1. A drive motor 614 is fixedly mounted on the outer wall of the mounting bracket 613 near the lower seed housing 1. The power output shaft of the drive motor 614 passes through… A drive wheel 615 is connected via a coupling, and a driven wheel 616 is rotatably mounted on the outer wall of the seeding machine housing 1. The same synchronous belt 617 is slidably mounted on the surfaces of the drive wheel 615 and the driven wheel 616. Multiple seeding discs 618 are rotatably mounted inside the seeding machine housing 1, and the multiple seeding discs 618 are fixedly connected together.

Each seeding disc 618 has several limiting holes 619 arranged in a circumferential array on its outer wall. The seeding tube 5 is arranged vertically corresponding to the seeding disc 618.

[0028] Specifically, seeds are added to the seed storage hopper 3, and the vibration motor 601 is started to make the seed storage hopper 3 vibrate inside the guide frame 2. The movable rod 603 slides along the inside of the guide seat 604 and compresses the first spring 605. The elasticity of the first spring 605 increases the vibration amplitude of the seed storage hopper 3. At the same time, the piston rod 609 slides along the inside of the outer sleeve 610, and the sealing disc 611 compresses the second spring 612. The elasticity of the second spring 612 further increases the vibration amplitude of the seed storage hopper 3, allowing the seeds to be discharged smoothly through the seed outlet 4. The seeds in the seed storage hopper 3 are discharged through the seed outlet 4. The seeds enter the interior of the seeding tube 5 and fall evenly into the limiting ports 619 on multiple seeding trays 618. The drive motor 614 is started to rotate the drive wheel 615, which drives the driven wheel 616 to rotate the multiple seeding trays 618 synchronously through the synchronous belt 617. Seeds continuously enter the multiple limiting ports 619. When the limiting port 619 filled with seeds rotates to the bottom, the seeds are discharged through the seeding machine box 1 and fall into the holes of the seed tray. Sowing is carried out in one row of holes at a time. Pushing the handle frame 9 moves the entire device until sowing of multiple rows of holes is completed. It saves time and effort and has high sowing efficiency.

[0029] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the top surface of the soil storage box 7 is provided with a soil filling port, and a sealing cover is rotatably installed inside the soil filling port. The bottom surface of the soil storage box 7 is fixedly connected to a plurality of soil discharge pipes 11 corresponding to the seeding pipe 5. A control valve is installed on the soil discharge pipe 11, and the soil leveling component 12 is located on the side of the soil discharge pipe 11 away from the seeding machine box 1.

[0030] Specifically, after sowing in a row of seed trays, the soil outlet pipe 11 moves above the seed trays, the control valve is opened, and the seedling soil in the soil storage box 7 is discharged through the soil outlet pipe 11 and falls into the seed trays, thus covering the seed trays with soil after sowing.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7In a preferred embodiment, the soil leveling component 12 includes a second mounting frame 1201, which is fixedly connected to the bottom surface of the soil storage box 7. A second drive motor 1202 is fixedly mounted at the middle of the top surface of the second mounting frame 1201. The power output shaft of the second drive motor 1202 is connected to a connecting rod 1203 via a coupling. A rotating plate 1204 is fixedly connected to the bottom of the connecting rod 1203. An eccentric sliding rod 1205 is rotatably mounted at the end of the rotating plate 1204 away from the connecting rod 1203. A sliding frame 1206 is provided below the rotating plate 1204, and the eccentric sliding rod 1205 is slidably mounted inside the sliding frame 1206. A fixing rod 1207 is fixedly connected to one end of the sliding frame 1206. A rack 1208 is fixedly connected to the bottom surface of the fixing rod 1207. A rack 1208 is rotatably mounted at the middle of the top surface of the second mounting frame 1201. There is a gear 1209, a rack 1208 meshing with the gear 1209, and a rack 2 1210 meshing with the surface of the gear 1209. The rack 1208 and rack 2 1210 are arranged in a circular array around the gear 1209. The bottom surfaces of the rack 1208 and rack 2 1210 are both fixedly connected to rack slides 1211. The top surfaces of the mounting bracket 2 1201 are both fixedly connected to guide rails 1212. The rack slides 1211 are slidably disposed inside the guide rails 1212.

The bottom surface of the rack slides 1211 is fixedly connected to a connecting rod 1213, which is slidably disposed in the groove. The bottom surface of the connecting rod 1213 is fixedly connected to a fixing plate 1214, and the bottom surface of the fixing plate 1214 is fixedly mounted with a soil comb claw 1215.

[0032] Specifically, after the holes are covered with soil, the drive motor 1202 is started, causing the connecting rod 1203 to drive the rotating plate 1204 to rotate. The eccentric slide rod 1205 slides along the inside of the sliding frame 1206, while simultaneously driving the rack 1208 to reciprocate along the inside of the guide rail frame 1212. At the same time, both rack 1208 and rack 2 1210 mesh with gear 1209, achieving synchronous reciprocating motion of rack 1208 and rack 2 1210. The fixed plate 1214 then drives the soil combing rake 1215 to reciprocate, combing the seedling soil on the seed tray, ensuring that the holes are evenly covered with soil, guaranteeing the soil covering effect, and thus improving the seed survival rate.

[0033] Working principle: Seeds are added to the seed storage hopper 3. The vibration motor 601 is activated, causing the seed storage hopper 3 to vibrate inside the guide frame 2. The movable rod 603 slides along the inside of the guide seat 604, compressing the first spring 605. The elasticity of the first spring 605 increases the vibration amplitude of the seed storage hopper 3. Simultaneously, the piston rod 609 slides along the inside of the outer sleeve 610, and the sealing disc 611 compresses the second spring 612. The elasticity of the second spring 612 further increases the vibration amplitude of the seed storage hopper 3. The seeds are discharged smoothly through the seed outlet 4. The seeds in the seed storage hopper 3 are discharged through the seed outlet 4 and enter the interior of the seed tube 5. The seeds fall evenly into the limiting ports 619 on the multiple seed trays 618. The drive motor 614 is started to rotate the drive wheel 615, which drives the driven wheel 616 to rotate the multiple seed trays 618 synchronously through the synchronous belt 617. The seeds continuously enter the multiple limiting ports 619. When the limiting port 619 filled with seeds rotates to the bottom, the seeds are discharged through the seed box 1 and fall into the seed tray. In the holes, seeds are sown in one row of holes at a time. Pushing the handle 9 moves the entire device until multiple rows of holes are sown, saving time and effort and increasing sowing efficiency. After sowing in one row of seed tray holes, the soil outlet pipe 11 moves above the holes, the control valve is opened, and the seedling soil in the soil storage box 7 is discharged through the soil outlet pipe 11 and falls into the holes, thus covering the sown holes with soil. After covering the holes with soil, the drive motor 1202 is started, causing the connecting rod 1203 to drive the rotating plate 1204 to rotate. The sliding rod 1205 slides along the inside of the sliding frame 1206, while simultaneously driving the rack 1208 to reciprocate along the inside of the guide rail frame 1212. At the same time, both rack 1208 and rack 2 1210 mesh with the gear 1209, achieving synchronous reciprocating motion of rack 1208 and rack 2 1210. The fixed plate 1214 then drives the soil combing rake claw 1215 to reciprocate, combing the seedling soil on the seed tray, so that the holes are evenly covered with soil, ensuring the soil covering effect, and thus improving the survival rate of seeds.
