Description

Technical Field

[0001] The present invention relates to the technical field of seedling transplanting, and particularly to an auxiliary device for seedling transplanting. Background Art

[0002] Traditional Chinese medicine planting includes multiple links such as land selection, seed selection and seedling raising, and transplanting. Among them, a transplanting machine is used for transplanting. The transplanting machine mainly consists of a traction frame assembly, a transmission system, a planting implement assembly, a seedling tray rack and a shock absorber, etc. The transplanting machine adopts an eccentric wheel disc link mechanism and a double cam plate structure, and simultaneously and precisely controls the transplanting link. The functions of double-wheel spiral pressing, opening holes in both side directions by the jaws of the seedling planter, planting seedlings, and covering soil by the soil covering wheel are realized; sprockets, chains, etc. are also used for rotation; double-wheel discs, double linkage shafts, and double cam plates are also used to control the opening, and a double-tooth-shaped jaw opening plate. When one side fails to open, the other side can still use the double-tooth-shaped opening and closing jaw plate to ensure the working reliability. Especially when the seedling transplanter encounters hard soil blocks, the shock absorber immediately plays a role to prevent the damage of the transplanting machine, making the transplanting machine durable and having a long service life.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1 - 10 , a seedling transplanting auxiliary device includes a mobile vehicle, which includes a traction frame assembly, wheels, a transmission structure, a planting structure 15, a seedling feeding assembly 3, a seat, and a seedling tray rack installed on the traction frame assembly. There is a sunshade on the seedling tray rack. The device also includes an auxiliary support assembly 1 and a fertilizer application assembly 4 installed on the traction frame assembly. The two auxiliary support assemblies 1 include a mounting member 110 connected to the traction frame assembly, and a support moving wheel 120 is rotatably installed in the mounting member 110. A locking hole 113 and a displacement hole 114 are formed in the mounting member 110; a pushing assembly 2 is provided on one side of the mounting member 110, and the pushing assembly 2 includes an inner plate 210 and an outer plate 240. A locking member 220 and a pushing member 230 are provided on the inner plate 210. The locking member 220 includes a screw rod 221 hinged to the inner plate 210, and the screw rod 221 is located in the locking hole 113. The pushing member 230 includes a pushing rod 231 hinged to the inner plate 210, and the pushing rod 231 is located in the displacement hole 114. The outer plate 240 includes an integrally formed vertical portion 241 and a V-shaped head 242; the inner plate 210 and the outer plate 240 are connected by an adjusting member 250. The adjusting member 250 includes a fixing block 251, an adjusting bolt 252, and a protruding portion 253. The fixing block 251 is connected to the top of the inner plate 210, the protruding portion 253 is connected to one side surface of the vertical portion 241, the adjusting bolt 252 passes through the fixing block 251 and rotates in place, and the adjusting bolt 252 is screwed into the protruding portion 253 in a threaded connection manner.

[0022] Referring to Figures 1 - 10, a seedling transplanting auxiliary device. The installation part 110 and the supporting moving wheels 120 can assist in supporting the traction frame assembly and do not hinder movement. The soil can be pushed and covered towards the position near the seedlings through the pushing component 2. By pushing the push rod 231 in the pushing displacement hole 114, a part of the inner plate 210 can be pushed to move by using or pulling the push rod 231. Specifically, the inner plate 210 rotates around the hinge position of the connecting block A222 and the hinge block A211. The screw rod 221 is threadedly connected with the locking hole 113. By adjusting the position of the screw rod 221 in the locking hole 113, the distance between the inner plate 210 and the installation part 110 can be adjusted. By adjusting the height of the adjusting bolt 252 in the fixing block 251, the height of the outer plate 240 can be adjusted. Since the vertical part 241 of the outer plate 240 is slidably attached to the surface of the inner plate 210, the V-shaped head 242 of the outer plate 240 is slidably sleeved on the inner plate 21, and the locking bolt 213 passes through the kidney-shaped hole 2411 and is connected to the inner plate 210. In this way, the vertical part 241 of the outer plate 240 is vertically limited, and further the entire outer plate 240 can move vertically on the surface of the inner plate 210, so as to adjust the height of the outer plate 240 and adjust the depth of the outer plate 240 for pushing the soil. After adjusting the inner plate 210 and the outer plate 240 to an appropriate inclination angle, when the equipment moves as a whole, the outer plate 240 can be used to turn over the soil from one side to the position where the seedlings are located.

[0023] Refer to Figures 1 - 10 , a seedling transplanting auxiliary device. A bayonet 111 is opened on the installation part 110. The bayonet 111 is for conveniently docking the installation part 11 with the frame rod of the traction frame assembly, and then the installation part 110 and the frame rod of the traction frame assembly are locked and connected through bolts. An installation opening 112 for accommodating the installation of wheels is also opened on the installation part 110. The screw rod 221 is threadedly connected in the locking hole 113. The push rod 231 is slidably inserted in the displacement hole 114. The width of the displacement hole 114 is greater than the width of the push rod 231. In this way, the push rod 231 has a certain range of movement in the displacement hole 114, which can prevent interference when the inner plate 210 and the outer plate 240 are adjusted, and prevent the positions of the screw rod 221 and the push rod 231 from being fixed during adjustment, resulting in the inability to adjust the inner plate 210 and the outer plate 240 obliquely.

[0024] Refer to Figures 1 - 10, a seedling transplanting auxiliary device. There are hinge block A211 and hinge block B212 on the inner plate 210. There are at least two hinge block A211 and hinge block B212. One end of the screw rod 221 is rotatably connected with a connecting block A222. The connecting block A222 is connected between the hinge block A211 through a connecting shaft. In this way, the connecting block A222 can rotate between the hinge block A211, and the screw rod 221 can rotate with respect to the inner plate 210. One end of the push rod 231 is fixed with a connecting block B232. The connecting block B232 is connected between the hinge block B212 through a connecting shaft. In this way, the connecting block B232 can rotate between the hinge block B212, and the push rod 231 can rotate with respect to the inner plate 210. A kidney-shaped hole 2411 is formed on the vertical part 241. A locking bolt 213 is screwed through the inner plate 210 in a threaded connection manner. The locking bolt 213 is inserted into the kidney-shaped hole 2411. After the vertical part 241 is moved and adjusted to a suitable position on the surface of the inner plate 210, the locking bolt 213 is tightened to lock and press the vertical part 241 on the inner plate 210.

[0025] Refer to Figures 1 - 10 , a seedling transplanting auxiliary device. The seedling dropping component 3 includes a central shaft 330 connected to the traction frame assembly. An upper disk 310 and a lower disk 320 are sleeved on the central shaft 330. The upper disk 310 and the lower disk 320 are fixedly connected to the central shaft 330. The upper disk 310 and the lower disk 320 maintain a relative position with one above the other. There are at least three communicating pipes 350 between the upper disk 310 and the lower disk 320. The top and bottom ends of the communicating pipe 350 are respectively connected to the bottom of the upper disk 310 and the top of the lower disk 320, and the upper disk 310, the lower disk 320 and the communicating pipe 350 are in communication. A conical hopper 340 is provided on the top of the upper disk 310. There are at least three conical hoppers 340. The conical hopper 340 is connected to the position where the upper disk 310 communicates with the communicating pipe 350. The conical hopper 340 is in communication with the communicating pipe 350. When the seedlings are put in from the conical hopper 340, the seedlings fall into the communicating pipe 350 from the conical hopper 340 and then drop down.

[0026] Refer to Figures 1 - 10, a seedling transplanting auxiliary device, the transmission structure includes a drive shaft A5, a tire shaft 6, a drive shaft B7, a positioning shaft A8, and a positioning shaft B11 rotatably connected to the traction frame assembly. The tire shaft 6 is used to connect the tire. A swing arm A9 is connected to the positioning shaft A8, and there is no rotation between the positioning shaft A8 and the swing arm A9. One end of the swing arm A9 is rotatably connected to a transmission rod A10. A swing arm B12 is connected to the positioning shaft B11, and there is no rotation between the positioning shaft B11 and the swing arm B12. One end of the swing arm B12 is rotatably connected to a transmission rod B13. A connecting protrusion is fixed on the transmission rod B13. The end of the transmission rod A10 away from the swing arm A9 is rotatably connected to the connecting protrusion. The end of the transmission rod B13 away from the transmission rod B13 is bolted with a group of transmission rods C14. The planting structure 15 is connected to the other end position of the group of transmission rods C14.

[0027] Refer to Figures 1 - 10 , a seedling transplanting auxiliary device, the bottom end of the central shaft 330 is connected with a bevel gear A331, and two bevel gears B510 are connected to the drive shaft A5. The bevel gear A331 and the bevel gear B510 are meshed and matched with each other. One drive shaft A5 and two tire shafts 6 are connected through a transmission component, one drive shaft B7 and two tire shafts 6 are connected through a transmission component, and one drive shaft B7 and two positioning shafts A8 and two positioning shafts B11 are connected through a transmission component. The transmission component for transmission connection is a combination of a chain and a sprocket; When the transmission structure moves, when the two tires move, the tire shaft 6 rotates. The rotation of the tire shaft 6 drives the drive shaft B7 and the drive shaft A5 to rotate through the transmission component. The rotation of the drive shaft A5 drives the central shaft 330 to rotate through the meshed bevel gear B510 and bevel gear A331. The rotation of the central shaft 330 drives the upper disk 310 and the lower disk 320 to rotate. In this way, the staff can sequentially place the seedlings into the conical hopper 340, and after falling into the connecting pipe 350, they fall into the planting structure 15; At the same time, the rotation of the drive shaft B7 drives the positioning shaft A8 and the positioning shaft B11 to rotate through the transmission component. The rotation of the positioning shaft A8 and the positioning shaft B11 drives the swing arm A9 and the swing arm B12 to rotate. The rotation of the swing arm A9 and the swing arm B12 drives the transmission rod A10 and the transmission rod B13 to move. In this way, because one end and the position near the other end of the transmission rod B13 are movably positioned, and the planting structure 15 is connected to the other end of the transmission rod B13 through the transmission rod C14, the transmission rod B13 and the transmission rod C14 can drive the planting structure 15 to insert into the ground. The movement trajectories of the transmission rod B13, the transmission rod C14, and the planting structure 15 are the same as the trajectory when the staff waves a hoe to hoe the ground. The transmission rod B13 and the transmission rod C14 are equivalent to the hoe rod, and the planting structure 15 is equivalent to the hoe. When the bottom end of the planting structure 15 is inserted into the soil and then lifted up, the bottom end of the planting structure 15 can be opened to release the seedlings; The specific movement trajectory is that the rotation of the swing arm A9 drives the overall lowering of the transmission rod A10, and the rotation of the swing arm B12 drives one end of the transmission rod B13 to move downward. In this way, the transmission rod C14 at the other end of the transmission rod B13 and the planting structure 15 at the end of the transmission rod C14 are all swung downward. Conversely, the rotation of the swing arm A9 drives the overall raising of the transmission rod A10, and the rotation of the swing arm B12 drives one end of the transmission rod B13 to move upward. In this way, the transmission rod C14 at the other end of the transmission rod B13 and the planting structure 15 at the end of the transmission rod C14 are all lifted upward, and the bottom of the planting structure 15 will open when it is lifted upward. Among them, the mobile vehicle, the traction frame assembly, the transmission structure, and the planting structure 15 can refer to the Fnong brand model yz-2 transplanter produced by Qufu Fnong Machinery Factory and the corresponding structures.

[0028] Refer to Figures 1 - 10 , a seedling transplanting auxiliary device. The fertilizer application component 4 includes a fertilizer box 410 arranged on the seedling tray frame. The fertilizer box 410 has a box cover at the top, and the interior of the fertilizer box 410 is divided into two placement cavities for accommodating fertilizers. The bottom ends of the two placement cavities are inclined towards one side. Two fertilizer application pipes 420 are connected to one side of the fertilizer box 410. A material control part 430 is arranged in the fertilizer application pipes 420. The fertilizer application component 4 also includes teeth 321 arranged at the top of the lower tray 320 near the outer circle. The area of the teeth 321 is arranged at least in three places. The fertilizer application component 4 also includes a transition pipe 360 connected to the traction frame assembly. The transition pipe 360 is located between the lower tray 320 and the planting structure 15 below the lower tray 320. When the lower tray 320 rotates, when the position where the lower tray 320 is connected to the bottom end of the communication pipe 350 turns above the transition pipe 360, the seedlings placed in the conical hopper 340 fall into the transition pipe 360 through the communication pipe 350, and then fall from the transition pipe 360 into the planting structure 15. The discharge end of the fertilizer application pipe 420 is connected and butted on the outside of the transition pipe 360, so that it is convenient for the fertilizer to slide from the placement cavity into the fertilizer application pipe 420 and then fall into the transition pipe 360; The material control member 430 includes a rotating shaft 432 passing through the lower fertilizer pipe 420. A material tray 431 is sleeved on the rotating shaft 432, and grooves for accommodating fertilizers are provided at both the top and bottom of the material tray 431. The material tray 431 is located in the lower fertilizer pipe 420, and there is no relative movement between the material tray 431 and the rotating shaft 432. One end of the rotating shaft 432 extends above the lower tray 320 and is fixedly connected to a gear 433, and the gear 433 is meshed and matched with the tooth 321. When the upper tray 310 and the lower tray 320 rotate, the staff sequentially place the seedlings. At the same time, when the lower tray 320 rotates and the position of the tooth 321 comes into contact with and meshes with the gear 433, the gear 433 is driven to rotate. The rotation of the gear 433 drives the rotation of the rotating shaft 432, and the rotation of the rotating shaft 432 drives the material tray 431 to rotate and turn over in the lower fertilizer pipe 420, so that the grooves at the top and bottom of the material tray 431 change positions, that is, the groove at the top of the material tray 431 is replaced with the one at the bottom, and the groove at the bottom of the material tray 431 is replaced with the one at the top. As a result, the fertilizer in the groove at the top of the material tray 431 falls into the lower fertilizer pipe 420. The fertilizer falling into the lower fertilizer pipe 420 then falls into the transition pipe 360 and then into the planting structure 15, where it is inserted into the soil together with the seedlings. And the groove at the bottom of the material tray 431 is replaced with the one at the top to re-accommodate the fertilizer; when the gear 433 leaves the tooth 321, the gear 433 does not rotate, the rotating shaft 432 does not rotate either, and the material tray 431 does not turn over in the lower fertilizer pipe 420, so the fertilizer does not fall.

[0029] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
