DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Example 1

[0052] like Figures 5 to 8 As shown, a seedling planter carrier includes a carrier frame, which includes a bottom frame 110 and an upper frame 120; a frame drive mechanism is provided at the bottom of the bottom frame 110, and the frame drive mechanism includes a plurality of drive wheels 130, all of which are located in the same plane;

[0053] The bottom frame 110 includes a first planting device installation area 110a and a soil covering mechanism installation area 110b, and the upper frame 120 includes a second planting device installation area 120a and a plant conveying mechanism installation area 120b; the second planting device installation area 120a is located directly above the first planting device installation area 110a, and the plant conveying mechanism installation area 120b is located directly above the soil covering mechanism installation area 110b.

[0054] Specifically, the bottom frame 110 includes a bottom frame 111, in which at least three bottom cross beams 112 are provided, and at least two bottom short vertical beams 113 are provided between the bottom cross beam 112 located in the middle position and its adjacent bottom cross beams 112; the front end drive wheel installation area is between the bottom cross beam at the front end and the bottom frame 111; the first planting device installation area 110a is between the bottom cross beam at the front end and the middle bottom cross beam; and the soil covering mechanism installation area 110b is between the middle bottom cross beam and the rear end bottom cross beam.

[0055] The upper frame 120 includes an upper frame 121, and at least one upper crossbeam is provided in the middle of the upper frame 121; the second planting device installation area 120a is between the upper crossbeam and the front end of the upper frame 121, and the plant conveying mechanism installation area 120b is between the upper crossbeam and the rear end of the upper frame 121.

[0056] The utility model divides the frame into two layers, and uses the longitudinal space of the upper and lower layers to set up a planting device, and uses the rear half of the lower space to accommodate the driving mechanism of the planting device, and uses the height between the bottom frame and the ground to set up a soil covering mechanism; at the same time, uses the rear half of the upper frame to set up a planting column conveying mechanism, fully utilizing the space advantage of the double-layer frame, effectively reducing the volume of the fuselage, so that it can cover the entire planting process, that is, conveying seedlings, digging holes, placing seedlings and covering the seedlings with soil.

[0057] In some embodiments, since the primary functional mechanism, namely the planting device, is integrated into the front end of the vehicle body, a front-wheel drive mechanism is employed to ensure efficient travel. Specifically, the two front-end drive wheels 130 are connected by a tie rod 131, with a frame drive device 132 positioned in the middle of tie rod 131. Furthermore, to reduce vehicle height and improve stability during movement, tie rod 131 is provided with frame connectors, including I-shaped connectors. The upper connecting plate of I-shaped connector 134 is fixedly connected to the lower surface of the front end of the bottom frame 110, while its lower connecting plate is fixedly connected to tie rod 131. The lower connecting plate of I-shaped connector 134 is fixedly connected to tie rod 131 via a U-shaped fork 135, and multiple sets of U-shaped forks 135 are provided.

[0058] In some embodiments, the frame connector further includes a structural reinforcement plate 136, which is disposed on the I-shaped connector 134. The structural reinforcement plate 136 is perpendicular to the vertical plate in the middle of the I-shaped connector 134 and is connected between the upper and lower connecting plates of the I-shaped connector 134. The reinforcement plate 136 further enhances the load-bearing capacity of the front-drive wheels and the secure connection between the front-drive wheels and the vehicle body.

[0059] In some embodiments, the drive wheel 130 located at the rear of the bottom frame 110 is a universal wheel, which is connected to the rear of the bottom frame 110 via an inclined link 137. By combining the front drive wheel with the universal rear wheel, the vehicle body's transformability can be improved, achieving the effect of adapting to various terrains.

[0060] In some embodiments, a hand-held push rod 140 is provided at the rear end of the carrying frame, and farmers can hold the push rod to operate the carrying vehicle when working, which makes operation more convenient.

[0061] Example 2

[0062] like Figures 1 to 20 As shown, an automatic seedling transplanter includes the aforementioned seedling transplanter carrier 100, on which a planting device 200, a plant conveying mechanism 300 and a soil covering mechanism 400 are integrated.

[0063] The carrier vehicle 100 includes a bottom frame 110 and an upper frame 120 mounted on the bottom frame; a planting device 200 is vertically mounted between the bottom frame 110 and the upper frame 120; a plant conveying mechanism 300 is mounted on the upper frame 120 and is located behind the upper end of the planting device 200; a soil covering mechanism 400 is mounted on the bottom frame 110 and is located behind the planting device 200;

[0064] The planting device 200 includes a planting dispenser 210, which is mounted on a mobile mechanism 220. The mobile mechanism 220 is installed between the bottom frame 110 and the upper frame 120. The planting dispenser 210 has a feeding bucket 211 at the top and an opening device 212 at the bottom. The opening device 212 is connected to the opening drive mechanism 230.

[0065] The plant conveying mechanism 300 includes a conveyor belt, the end of which is located directly above the feeding bucket 211 ; the soil covering mechanism 400 includes a scraper plate 410 , which is located directly behind the opener 212 .

[0066] The present invention sets the carrier 100 as a two-layer vehicle, and the planting device 200 is vertically arranged at the front end of the carrier 100, occupying the front half space between the bottom frame and the upper frame, and at the same time, an opener driving mechanism is separately arranged at the rear end of the bottom frame, and the opener of the planting device is separately controlled by the opening driving mechanism to realize digging, and the opener driving mechanism is arranged at the rear half of the bottom frame, and the rear half of the bottom frame is also provided with a soil covering mechanism, and the planted plants are buried in the soil by the soil covering mechanism; a plant conveying mechanism is arranged at the rear end of the upper frame, and the seedlings are delivered by the plant conveying mechanism, and the conveyor belt end of the plant conveying mechanism is located just above the feeding bucket 211, which can ensure that the plants can be accurately put into the planting device 200. The present invention can automatically realize seedling delivery, soil digging, seedling planting, and soil covering, covering the entire operation process of the plant seedling planting process, making full use of the space of the double-layer carrier, achieving the effect of realizing all functions, but with a smaller overall body, and the carrier can adapt to various terrain environments, thereby improving the versatility of agricultural machinery.

[0067] like Figures 9 to 14 As shown, in some embodiments, a planting mount is provided on the mobile mechanism 220. The planting mount includes a mounting frame 224, with a first right-angle connecting plate 225a connected to one side of the mounting frame 224. A feeding bucket 211 is mounted on the upper surface of the mounting frame 224. An opener 212 is disposed below the mounting frame 224, with the lower end of the feeding bucket 211 aligned with the upper end of the opener 212. The mounting frame and the first right-angle connecting plate 225a form the planting mount, which is positioned between the bottom and upper frames. This ensures that when the mobile mechanism reaches its uppermost position, the feeding bucket 211 remains at the end of the conveyor belt, further controlling the height of the entire machine body.

[0068] like Figures 9 to 14 As shown, in some embodiments, the mobile mechanism 220 includes a screw nut 221, which is mounted on a ball screw 222. The upper end of the ball screw 222 is fixed to the middle of the upper frame 120, and the lower end is fixed to the middle of the bottom frame 110. A connecting cross plate 223 is provided on the screw nut 221. Planting mounts are provided at both ends of the connecting cross plate 223. The planting mounts are connected to the ends of the connecting cross plate 223 via a first right-angle connecting plate 225a. The entire mobile mechanism 220 is located in the middle, with its two sides connected to the two planting mounts via the connecting cross plates 223. This ensures planting efficiency despite the small size of the machine.

[0069] Furthermore, since the design includes two planting devices, to ensure stability when operating in hilly or mountainous areas, a second right-angle connecting plate 225b is connected to the outside of the mounting frame 224. The upper end of the second right-angle connecting plate 225b is connected to a first slider 226, which is mounted on a first slide bar 227. The upper end of the first slide bar 227 is connected to the outer frame of the upper frame 120, and the lower end is connected to the outer frame of the bottom frame 110. More preferably, the present invention uses a double slide bar as the first slide bar 227, which has greater structural strength, further increasing the structural strength of the planting device and adapting to different terrains.

[0070] like Figures 5 to 8 As shown, in some embodiments, in order to enhance the structural strength of the mobile mechanism and improve the ability of the fuselage to adapt to the terrain, the bottom frame 110 includes a bottom frame 111, and a first bottom beam 112a, a second bottom beam 112b and a third bottom beam 112c are provided in the bottom frame 111. The first bottom beam 112a, the second bottom beam 112b and the third bottom beam 112c constitute the bottom beam 112, and a first planting device installation area 110a is formed between the first bottom beam 112a and the second bottom beam 112b, a soil covering mechanism installation area 110b is formed between the second bottom beam 112b and the third bottom beam 112c, and a front end drive wheel installation area is formed between the first bottom beam 112a and the bottom frame 111. Specifically, the first bottom crossbeam 112a and the second bottom crossbeam 112b are connected midway by a first short beam 113, and the lower end of the ball screw 222 is disposed on the first short beam 113. The upper frame 120 includes an upper frame 121, within which a first upper crossbeam is disposed. A second planting device mounting area 120a is defined between the first upper crossbeam and the front crossbeam of the upper frame 121, while a plant conveying mechanism mounting area 120b is defined between the first upper crossbeam and the rear crossbeam of the upper frame 121. Specifically, the first upper crossbeam is located directly above the second bottom crossbeam 112b; the first upper crossbeam is connected to the front end of the upper frame by a second short beam; the second short beam is located directly above the first short beam, and the upper end of the ball screw 222 is disposed on the second short beam. More preferably, two first short beams and two second short beams are provided. Furthermore, the upper and lower ends of the ball screw 222 are fixed to the first short beam and the second short beam through separate screw mounting plates 228, and a screw motor mounting plate 229 is provided on the screw mounting plate 228 at the upper end. The lower surface of the screw motor mounting plate 229 is connected to a screw drive motor, and the power output end of the screw drive motor and the end of the ball screw 222 are both provided with a first synchronous wheel, and the two first synchronous wheels are connected by a first synchronous belt.

[0071] Specifically, such as Figures 5 to 8As shown, in some embodiments, to ensure the carrier vehicle can move automatically and adapt to different terrains, a frame drive mechanism is provided at the bottom of the base frame 110. The frame drive mechanism includes multiple drive wheels 130, all of which are located in the same plane. The two drive wheels 130 at the front are connected by a cross-rod 131, and a frame drive device 132 is provided in the middle of the cross-rod 131. The cross-rod 131 is provided with a frame connector, which includes an I-shaped connector. The upper connecting plate of the I-shaped connector 134 is fixedly connected to the lower surface of the front end of the base frame 110, and its lower connecting plate is fixedly connected to the cross-rod 131. The lower connecting plate of the I-shaped connector 134 is fixedly connected to the cross-rod 131 via a U-shaped fork 135, and multiple sets of U-shaped forks 135 are provided.

[0072] In some embodiments, to further ensure the secure connection between the base frame and the front wheel, the frame connector further includes a structural reinforcement plate 136 disposed on the I-shaped connector 134. The structural reinforcement plate 136 is perpendicular to the vertical plate in the middle of the I-shaped connector 134 and is connected between the upper and lower connecting plates of the I-shaped connector 134. The drive wheel 130 located at the rear of the base frame 110 is a universal wheel and is connected to the rear of the base frame 110 via a tilt link 137.

[0073] In some embodiments, in order to facilitate manual pushing and moving of the entire agricultural machine, a hand-held push rod 140 is provided at the rear end of the supporting frame.

[0074] like Figures 13 and 14 As shown, in some embodiments, an opening drive mechanism 230 is provided on the second bottom crossbeam 112b and the third bottom crossbeam 112c, and the opening drive mechanism 230 is connected to the opening device 212 via a second connecting rod 238. By driving the opening device to open and close independently through the opening drive mechanism, the insertion of the pillar into the ground can be independently controlled. In conjunction with the automatic operation of the carrier vehicle, the planting distance between plants can be adjusted.

[0075] like Figure 9 to Figure 3 as well as Figure 19 As shown, in some embodiments, the opener is formed by at least two duckbill opening pieces 212a, and the overall shape of the opener is conical, which is convenient for the opener to be inserted into the soil; two duckbill opening pieces are used in this embodiment, because the opening drive mechanism 230 of the utility model can only drive the duckbill opening piece 212a on one side to shake, so only two duckbill opening pieces are needed, one duckbill opening piece is shaken open to enable the plant to fall into the pit, and the other duckbill opening piece is always kept upright to straighten the plant and ensure that the plant will not tilt or fall.

[0076] like Figure 9 to Figure 3 as well as Figure 19As shown, in some embodiments, a flange is provided around the arcuate opening at the upper end of the duckbill opening piece 212a, and a pair of mounting tabs 213 are vertically provided on the flange. The mounting tabs 213 are provided with mounting holes. Correspondingly, a lug extends from the side of the mounting frame 224, and the lug also has a mounting hole. The connecting rod 214 passes through one mounting tab, two mounting tabs of the mounting frame, and another mounting tab in sequence, so that the duckbill opening piece 212a is hung on the side of the mounting frame 224 and can rotate relative to the connecting rod. In order to enable the opening piece to rotate relative to the connecting rod 214, the upper end of one of the mounting tabs 213 is connected to one end of a second connecting rod 238, and the other end of the second connecting rod 238 is connected to one end of a hook-shaped connecting rod 236 of the opening drive mechanism 230.

[0077] like Figure 13 As shown, in some embodiments, the opening drive mechanism 230 includes an opening drive motor, and the power output end of the opening drive motor is provided with a first bevel gear 231, the first bevel gear 231 is meshed with the second bevel gear 232, and the second bevel gear 232 is provided in the middle area of ​​the power transmission rod 233, and opening cams 234 are respectively installed on both sides of the power transmission rod 233. Through an opening drive motor, it serves as the power source for two openers to dig the land at the same time, thereby ensuring the consistency of the operation of the two openers and improving the planting quality; more specifically, in order to facilitate the installation of the opening drive mechanism on the automated planting agricultural machinery, the two ends of the power transmission rod 233 are fixed on the vertical mounting plate 237, and the two vertical mounting plates 237 are connected by a connecting base plate 239; the vertical mounting plate 237 extends forward with a connecting rod mounting area, and the hook-shaped connecting rod 236 is connected to the connecting rod mounting area.

[0078] Specifically, the opening cam 234 cooperates with a follower 235, which is located at one end of a hook-shaped connecting rod 236. The hook of the hook-shaped connecting rod 236 is rotatably connected to a vertical mounting plate 237, allowing the hook-shaped connecting rod 236 to rotate relative to its center. The upper end of the hook-shaped connecting rod 236 is connected to a second connecting rod 238, and the upper end of the second connecting rod 238 is connected to the upper end of the mounting bracket 213. When the opening cam rotates and presses the follower downward, the center of the hook-shaped connecting rod rotates relative to the vertical mounting plate 237, causing its other end to rise upward. The upward lifting force is redirected by the inclined second connecting rod 238. Furthermore, the opening bracket can rotate relative to the connecting rod 214. Therefore, when force acts on the mounting bracket, the mounting bracket drives the opening bracket to rotate relative to the connecting rod, opening the lower end of the opening bracket and allowing seedling planting. When the opening cam and the follower are no longer in contact, the opening bracket returns to its original position. In this way, the mechanical power of the opener for opening the seedlings is completely independent of other powers of the machine body, and the seedling throwing operation is controlled independently.

[0079] like Figures 5 to 8As shown, in some embodiments, a second upper crossbeam is provided in the upper vehicle frame 121, and the plant conveying mechanism 300 is mounted between the first upper crossbeam and the second upper crossbeam;

[0080] The plant conveyor mechanism 300 includes two sets of conveyor belts, each of which is a roller belt 302, mounted on either end of a pair of drive rollers 301. At least one of the drive rollers 301 is equipped with a conveyor mechanism synchronous pulley 304. The conveyor mechanism uses two belts to simultaneously transport two planting devices, significantly improving planting efficiency.

[0081] In some embodiments, both ends of the transmission roller 301 are respectively fixed on a pair of longitudinal outer crossbeams 303, and one end of one of the transmission rollers 301 is provided with a conveying mechanism synchronous wheel 304, and the conveying mechanism synchronous wheel 304 is connected to the synchronous wheel on the power output end of the seedling transport drive mechanism 305 through a second synchronous wheel belt 311;

[0082] A support leg 306 is provided below the longitudinal outer crossbeam 303, and a transverse connecting block 307 is provided at the end of the support leg 306. This ensures the structural stability of the conveying mechanism to adapt to different terrains.

[0083] In some embodiments, two sets of roller belts 302 are positioned between two drive rollers 301; the two sets of roller belts 302 are positioned on either side of the drive rollers 301. Sidewall mounting posts 308 are positioned on the inner sides of the two sets of roller belts 302. L-shaped sidewalls 309 are positioned on the sidewall mounting posts 308 and the longitudinal outer crossbeams 303. These sidewalls are positioned along the sides of the roller belts 302. These sidewalls prevent plants from falling during transport.

[0084] In some embodiments, to provide power to the plant mechanism, roller mounting blocks 310 are provided at the ends of the longitudinal outer crossbeams 303. One end of the roller mounting block 310 is connected to the outer side wall of the longitudinal outer crossbeam 303, and the other end is provided with a roller mounting hole. The end of the transmission roller 301 is mounted within the roller mounting hole.
