Description

Technical Field

[0001] The present invention relates to the technical field of seed and seedling cultivation, and particularly to a turnover device for crop seedlings with a protection structure. Background Art

[0002] Seed and seedling cultivation needs to be carried out in a special cultivation frame, which can better provide the nutrients required for seed growth and facilitate monitoring of the seed growth situation. The cultivation columns in the prior art are generally composed of multiple planting grooves. The soil required for cultivation is added to the grooves, and then the seeds are buried for cultivation. After the seeds germinate, they are transferred to other planting areas.

[0003] In the above process, when manually taking out and transplanting the seedling, it takes a lot of time to take out the soil and the seedlings one by one, and the soil is also prone to falling off or loosening during the transportation process, affecting the survival rate of the transplanted seedlings. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a turnover device for crop seedlings with a protection structure to solve the problems raised in the above background art. The structure of the present invention is novel. Through the cooperation of the planting component and the pushing component, when it is necessary to take out the seedlings, the planting soil is pushed out together, and the soil and the seedlings are supported by the inserting plate. The wrapping component is used to shape and wrap the soil block, which is convenient for uniformly taking out the soil block and the seedlings, avoiding the loosening and falling off of the soil during the transportation process, and the planting component can quickly carry out the next group of seedling cultivation.

[0005] To achieve the above purpose, the present invention is realized by the following technical solutions: A turnover device for crop seedlings with a protection structure includes a bottom plate.

A pushing plate is provided at the bottom of the bottom plate, and a top column is fixed at a position corresponding to each planting frame on the surface of the pushing plate. The top column slidably passes through the bottom plate and is fixedly connected to the tray. A wrapping component is provided on the top of the bottom plate at the position of the planting frame. The wrapping component includes an installation frame. An installation frame is fixed on one side of the top of the bottom plate, and winding shafts are rotatably installed at positions corresponding to both sides of the planting frame inside the installation frame. A tape is wound inside the winding shaft. A sliding frame is provided on the other side of the bottom plate, and a spring clip is fixed at a position corresponding to the tape on the sliding frame. The movable end of the tape is clamped inside the spring clip. A pushing component is provided on one side of the back of the bottom plate. The pushing component includes a connecting plate. An inserting plate is fixed at a position corresponding to the trays in the same straight line on the connecting plate, and the inserting plate can be slidably inserted into the top of the tray.

[0006] Furthermore, the planting component further includes a first spring plug rod. The top four corners of the bottom frame are slidably inserted with the first spring plug rod, and the top of the first spring plug rod is fixedly connected to the support plate. The top of the planting frame is provided with cover plates on both sides.

[0007] Furthermore, the top four corners of the planting frame are slidably inserted with second spring plug rods, and the tops of the second spring plug rods are rotatably connected to the cover plates through rotating shafts and torsion springs.

[0008] Furthermore, the pushing component further includes an inserting frame. The inserting frame is provided at the bottom of the connecting plate, and the inserting frame is slidably inserted inside the bottom plate. A slot is opened on the surface of the support plate corresponding to the inserting plate, and the inserting plate is slidably inserted into the slot of the support plate on the same straight line.

[0009] Furthermore, sliding rods are fixed at both ends of the inserting frame at the bottom of the connecting plate, and the connecting plate is slidably sleeved on the sliding rods. A third spring is sleeved on the surface of the sliding rods between the connecting plate and the inserting frame.

[0010] Furthermore, limiting frames are fixed at both ends of the connecting plate, and a cross plate is inserted inside the limiting frames. Gears are rotatably installed at both ends of the bottom plate through bearings. Tooth plates are engaged and connected to both sides of the gears. One side tooth plate of the gear is fixedly connected to the pushing plate, and the other side gear of the gear is fixedly connected to the cross plate.

[0011] Furthermore, the wrapping component further includes a sliding plate fixed at the outer end of the installation frame, and the sliding frame is slidably sleeved on the surface of the sliding plate.

[0012] Furthermore, transverse telescopic plates are fixed on both sides of the bottom plate, and vertical telescopic plates are fixed at the extending ends of the transverse telescopic plates. A moving plate is fixed at the top of each of the two vertical telescopic plates.

[0013] Furthermore, the two groups of moving plates are arranged in a staggered manner up and down, and connecting rods are equidistantly fixed on the surfaces of the moving plates. The connecting rods of the two groups of moving plates are also arranged in a staggered manner.

[0014] Furthermore, extrusion rods are fixed on the outer side surfaces of the connecting rods corresponding to the tape, and the extrusion rods are in extrusion contact with the outer edges of the tape.

[0015] Advantages of the present invention:

[0016] 1. The present invention buries the planting frame inside the soil, supports it through the pallet, and maintains air permeability through the air vents in the pallet and the bottom frame. The cover plate at the upper end limits the top of the soil block. When taking it out, the cover plate can be moved upward and flipped open through the extrusion effect, facilitating the removal of the soil block. Through the movement of the push plate and the top column, the pallet is driven to move upward along the top of the planting frame, and the soil inside the planting frame can be completely pushed out, facilitating the transportation of the seedlings.

[0017] 2. The present invention rotates the gear, which meshes with the toothed plates on both sides, driving the push plate and the top column to move upward. The soil block is pushed out of the planting frame through the pallet. At the same time, the connecting plate moves downward along the sliding rod, and the insertion plate moves to the position where the push plate is pushed out, keeping the movement of the soil block being pushed out and the movement of the insertion plate synchronized. Subsequently, the insertion frame is manually pushed to move, and the insertion plate is inserted into the slot of the pallet in a straight line along the top of the planting frame to support the bottom of the soil block. At the same time, the cross plate slides along the limit frame to avoid interfering with the movement of the connecting plate. The insertion plate cooperates with the wrapping component, which can facilitate the removal of the wrapped soil block and the seedlings from the planting frame.

[0018] 3. When cultivating seeds in the present invention, the moving plate, the connecting rod, the extrusion rod, etc. maintain a certain distance from the planting frame through the elongation of the vertical telescopic plate to avoid interfering with the growth of the seeds. When the seedlings need to be taken out, first, the movable end of the tape is clamped inside the spring clip of the sliding frame. Subsequently, the sliding frame slides along the sliding plate to cover the side plate of the planting frame in a straight line with the tape. The adhesive surfaces of the tape on both sides of one planting frame are opposite. Then, the height of the vertical telescopic plate is adjusted, and the horizontal and vertical telescopic plate is moved so that the extrusion plate can be inserted outside the tape. After the soil block of the seedlings is pushed out, the two moving plates are manually moved in the reverse direction, driving the extrusion rods to move in different directions. As a result, while the tape on both sides is in direct contact with the soil block, the extrusion rods will drive the tape to move, causing the tape on both sides of the planting frame to stick together, forming a wrapping of the soil block, thereby maintaining the stability of the soil during the removal and transportation processes and preventing it from loosening.

[0019] 4. Compared with the prior art, the present invention, through the cooperation of the planting component and the pushing-out component, when the seedlings need to be taken out, the planting soil is pushed out together, and the soil and the seedlings are supported by the insertion plate. The wrapping component is used to shape and wrap the soil block, facilitating the unified removal of the soil block and the seedlings, preventing the soil from loosening and falling off during the transportation process, and enabling the planting component to quickly carry out the next group of seedling cultivation.

[0029] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0030] Please refer to Figures 1 to 8, the present invention provides a technical solution: a turnover device for crop seedlings with a protection structure, including a bottom plate 1. A planting component 2 is provided on the top of the bottom plate 1. The planting component 2 includes a planting frame 21. A plurality of planting frames 21 are equidistantly arranged on the top of the bottom plate 1, and a mounting frame 27 is fixed on the periphery of the planting frame 21. The mounting frame 27 is fixed on the bottom plate 1. A bottom frame 24 is fixed to the bottom of the planting frame 21, and the bottom of the bottom frame 24 is fixedly connected to the bottom plate 1. A tray 22 is slidably connected inside the planting frame 21. Ventilation grooves 25 are formed on the surfaces of the tray 22 and the bottom frame 24. A push plate 11 is provided at the bottom of the bottom plate 1, and a top column 12 is fixed at the position corresponding to each planting frame 21 on the surface of the push plate 11. The top column 12 slidably passes through the bottom plate 1 and is fixedly connected to the tray 22. A wrapping component 4 is provided at the top of the bottom plate 1 where the planting frame 21 is located. The wrapping component 4 includes a mounting frame 43. A mounting frame 43 is fixed to one side of the top of the bottom plate 1, and winding shafts 44 are rotatably mounted inside the mounting frame 43 at positions corresponding to both sides of the planting frame 21. A tape 45 is wound inside the winding shaft 44. A sliding frame 49 is provided on the other side of the bottom plate 1, and a spring clip 411 is fixed at the position corresponding to the tape 45 on the sliding frame 49. The movable end of the tape 45 is clamped inside the spring clip 411. A pushing component 3 is provided on one side of the back of the bottom plate 1. The pushing component 3 includes a connecting plate 32. An insertion plate 39 is fixed to the connecting plate 32 at the position corresponding to the tray 22 in the same straight line, and the insertion plate 39 can be slidably inserted into the top of the tray 22. When using the device, cultivate soil and seeds in the planting frame 21. After the seeds are cultivated, the soil blocks and seedlings are pushed out of the planting frame 21 through the tray 22. The insertion plate 39 of the pushing component 3 is inserted into the bottom of the soil block to support the bottom of the soil block and the seedlings. The wrapping component 4 wraps the four sides of the soil to prevent the soil blocks from loosening and falling off during the transportation process. Use scissors to cut the tape 45 on the winding shaft 44, and then remove the wrapped soil block through the insertion plate 39 and send it out together.

[0031] In this embodiment, the planting component 2 further includes a first spring plug 28. The first spring plugs 28 are slidably inserted at the four corners of the top of the bottom frame 24, and the top of the first spring plug 28 is fixedly connected to the tray 22. On both sides of the top of the planting frame 21, there are cover plates 26. The second spring plugs 29 are slidably inserted at the four corners of the top of the planting frame 21, and the top of the second spring plug 29 is rotatably connected to the cover plate 26 through a rotating shaft and a torsion spring. Both the first spring plug 28 and the second spring plug 29 are common structures composed of a plug and a spring. The soil is buried inside the planting frame 21, supported by the tray 22, and the air permeability is maintained through the air-permeable grooves 25 in the tray 22 and the bottom frame 24. The cover plate 26 at the upper end limits the top of the soil block. When taking it out, the cover plate 26 can be moved upward and flipped open through the extrusion effect, facilitating the removal of the soil block. Through the movement of the push plate 11 and the top column 12, the tray 22 is driven to move upward along the top of the planting frame 21, and the soil in the planting frame 21 can be completely pushed out, facilitating the transfer of the seedlings.

[0032] In this embodiment, the pushing-out component 3 further includes an insertion frame 31. The insertion frame 31 is provided at the bottom of the connecting plate 32 and is slidably inserted inside the bottom plate 1. A slot 23 is formed on the surface of the tray 22 corresponding to the insertion plate 39, and the insertion plate 39 is slidably inserted into the slot 23 of the tray 22 in the same straight line. Sliding rods 33 are fixed at both ends of the insertion frame 31 located at the bottom of the connecting plate 32, and the connecting plate 32 is slidably sleeved on the sliding rods 33. A third spring 34 is sleeved on the surface of the sliding rod 33 between the connecting plate 32 and the insertion frame 31. Limit frames 36 are fixed at both ends of the connecting plate 32, and a cross plate 35 is also inserted inside the limit frames 36. Gears 37 are rotatably installed at both ends of the bottom plate 1 through bearings. Tooth plates 38 are engaged on both sides of the gear 37. One tooth plate 38 on one side of the gear 37 is fixedly connected to the push plate 11, and the other gear 37 on the other side of the gear 37 is fixedly connected to the cross plate 35. In the initial state, the insertion frame 31 is away from the bottom plate 1. When the soil block needs to be taken out, the gear 37 is rotated. The gear 37 meshes with the tooth plates 38 on both sides, driving the push plate 11 and the top column 12 to move upward. The soil block is pushed out of the planting frame 21 through the tray 22. At the same time, the connecting plate 32 moves downward along the sliding rod 33, and the insertion plate 39 moves to the position where the push plate 11 is pushed out, keeping the pushing out of the soil block and the movement of the insertion plate 39 synchronized. Subsequently, the insertion frame 31 is manually pushed to move, and the insertion plate 39 is inserted into the slot 23 of the tray 22 in a straight line along the top of the planting frame 21 to support the bottom of the soil block. At the same time, the cross plate 35 slides along the limit frame 36 to avoid interfering with the movement of the connecting plate 32. The insertion plate 39 cooperates with the wrapping component 4, which can facilitate the removal of the wrapped soil block and seedlings from the planting frame 21.

[0033] In this embodiment, the wrapping component 4 further includes a sliding plate 48 fixed to the outer end of the mounting frame 43, and a sliding carriage 49 is slidably sleeved on the surface of the sliding plate 48. Transverse telescopic plates 41 are fixed to both sides of the bottom plate 1, and vertical telescopic plates 42 are fixed to the extending ends of the transverse telescopic plates 41. A moving plate 46 is fixed to the top of each of the two vertical telescopic plates 42. The two groups of moving plates 46 are arranged vertically staggered, and connecting rods 47 are equidistantly fixed on the surface of the moving plate 46. The connecting rods 47 of the two groups of moving plates 46 are also arranged in a staggered manner. An extrusion rod 410 is fixed to the outer side surface of the connecting rod 47 corresponding to the tape 45, and the extrusion rod 410 is in extrusion contact with the outer edge of the tape 45. When cultivating seeds, the moving plate 46, the connecting rod 47, the extrusion rod 410, etc. maintain a certain distance from the planting frame 21 through the extension of the vertical telescopic plate 42 to avoid interfering with the growth of the seeds. When it is necessary to take out the seedlings, first, the movable end of the tape 45 is clamped inside the spring clip 411 of the sliding carriage 49, and then the sliding carriage 49 slides along the sliding plate 48 to cover the side plates of the planting frame 21 in a straight line. The adhesive surfaces of the tapes 45 on both sides of one of the planting frames 21 are opposite. Then, the height of the vertical telescopic plate 42 is adjusted, and the horizontal and vertical telescopic plates are moved so that the extrusion plate can be inserted outside the tape 45. After the soil block of the seedling is pushed out, the two moving plates 46 are manually moved in the reverse direction, driving the extrusion rods 410 to move in different directions. As a result, while the two sides of the tape 45 are in direct contact with the soil block, the extrusion rod 410 drives the tape 45 to move, causing the tapes 45 on both sides of the planting frame 21 to adhere, forming a wrap around the soil block, thereby maintaining the stability of the soil during the process of taking out and transporting and preventing it from loosening. In this structure, simply put, although the lengths of the connecting rods 47 are the same, the connected extrusion rods 410 are not exactly the same. That is, the extrusion rod 410 connected to the lower moving plate 46 moves outward, indicating that the connecting rod 47 is connected to the extrusion rod 410 on the right side of the planting frame 21, and the upper moving plate 46 moves inward, with the connecting rod 47 connected to the extrusion rod 410 on the left side of the planting frame 21. Although multiple connecting rods 47 in different directions on a straight line are on the same straight line, they are connected to different moving plates 46, forming movements in different directions. As a result, the extrusion rods 410 on both sides of the planting frame 21 will move towards the middle of the planting frame 21, and then the tape 45 is squeezed and wrapped at the middle position of the planting frame 21, forming a form of four-sided wrapping of the soil block.

[0034] When using the device, the soil is buried inside the planting frame 21, supported by the pallet 22, and the air permeability is maintained through the air vents 25 in the pallet 22 and the bottom frame 24. The cover plate 26 at the upper end limits the top of the soil block. When taking it out, the cover plate 26 can be moved upward and flipped open through the extrusion effect, facilitating the removal of the soil block. Through the movement of the push plate 11 and the top column 12, the pallet 22 is driven to move upward along the top of the planting frame 21, and the soil in the planting frame 21 can be completely pushed out. In the initial state, the inserting frame 31 is far from the bottom plate 1. When the soil block needs to be taken out, the gear 37 is rotated. The gear 37 meshes with the two side rack plates 38, driving the push plate 11 and the top column 12 to move upward. The soil block is pushed out of the planting frame 21 through the pallet 22. At the same time, the connecting plate 32 moves downward along the sliding rod 33, and the inserting plate 39 moves to the position where the push plate 11 is pushed out, keeping the pushing out of the soil block and the movement of the inserting plate 39 synchronized. Subsequently, the inserting frame 31 is manually pushed to move, and the inserting plate 39 is inserted into the slot 23 of the pallet 22 in a straight line along the top of the planting frame 21 to support the bottom of the soil block. At the same time, the cross plate 35 slides along the limiting frame 36 to avoid interfering with the movement of the connecting plate 32. The inserting plate 39 cooperates with the wrapping assembly 4, which can facilitate the removal of the wrapped soil block and the seedling from the planting frame 21. When cultivating seeds, the moving plate 46, the connecting rod 47, the extrusion rod 410, etc. maintain a certain distance from the planting frame 21 through the elongation of the vertical telescopic plate 42 to avoid interfering with the growth of the seeds. When the seedling needs to be taken out, first, the movable end of the tape 45 is clamped inside the spring clip 411 of the sliding frame 49. Subsequently, the sliding frame 49 slides along the sliding plate 48 to cover the tape 45 on the side plate of the planting frame 21 in a straight line. The adhesive surfaces of the tape 45 on both sides of one of the planting frames 21 are opposite. Subsequently, the height of the vertical telescopic plate 42 is adjusted, and the horizontal and vertical telescopic plate is moved so that the extrusion plate can be inserted outside the tape 45. After the soil block of the seedling is pushed out, the two moving plates 46 are manually moved in the reverse direction, driving the extrusion rods 410 to move in different directions. As a result, while the two sides of the tape 45 are in direct contact with the soil block, the extrusion rods 410 drive the tape 45 to move, causing the tape 45 on both sides of the planting frame 21 to adhere, forming a wrap for the soil block, thereby maintaining the stability of the soil during the removal and transportation process and preventing it from loosening. Use scissors to cut the tape 45 on the winding shaft 44, and then remove the wrapped soil block through the inserting plate 39 and send it out together.
