Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a semi-automatic transplanter that allows manual seedling feeding and automatic planting. Background Technology

[0002] Agricultural machinery refers to various machines used in crop cultivation and animal husbandry, as well as in the initial processing and handling of agricultural and livestock products. These machines play a core role in modern agriculture, significantly improving production efficiency and reducing labor costs. Specifically, agricultural machinery includes categories such as agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, livestock machinery, and agricultural transportation machinery, covering all aspects of the entire agricultural production chain.

[0003] A transplanter is a type of agricultural machinery specifically designed for transplanting seedlings, replacing traditional manual labor. A transplanter mainly consists of working components such as a seedling feeder, seedling guide tube, seedling delivery device, furrow opener, and soil covering wheel. The seedling feeder receives and places the seedlings, the seedling guide tube directs the seedlings to the planting point, the seedling delivery device ensures continuous seedling transport, the furrow opener creates planting furrows in the soil, and the soil covering wheel covers and compacts the soil. These components work together to achieve a precise and efficient planting process.

[0004] Existing transplanters can only transplant the same type of seedling when automatically transplanting two rows, due to structural limitations and the singular nature of their automated control systems. For example, in applications requiring simultaneous transplanting of different seedling types in two rows—such as transplanting male seedlings to provide pollen while simultaneously transplanting female seedlings for pollination—existing transplanters cannot meet the demands, leading to low planting efficiency or additional manual intervention. This limitation is particularly pronounced in high-precision agricultural operations such as hybrid crop breeding, necessitating an improved solution. Therefore, a semi-automatic transplanter with manual seedling placement and automatic planting has been designed. It allows operators to manually place different seedling types while the automatic planting mechanism completes steps such as trenching and soil covering, thus balancing flexibility and automation to effectively address diverse planting needs.

A set of racetrack-shaped steel wire guide rails 504 are symmetrically installed on both sides of the center line of the bottom door plate 503. A set of first sprocket assemblies 505 is respectively provided at the four semi-rounded corners of the inner ring of each set of steel wire guide rails 504. The outer gear surfaces of the four sets of first sprocket assemblies 505 are meshed and connected. There is a transmission chain 506, and a number of first large-mouth seedling cups 507 are installed in an orderly manner on the outer meshing surface of the transmission chain 506. Two second sprocket assemblies 508 are installed on the left and right sides below the gearbox 501. Two of the four sets of first sprocket assemblies 505 located on the two sides near the gearbox 501 are connected to third sprocket assemblies 509.

A first cover 10 covering the gearbox 501 is installed on the top of the second square tube bracket 104.

[0022] Please see Figure 9 In the above embodiment, the soil covering device 6 includes a pair of bearing seats 601 symmetrically installed on the front crossbeam of the chassis frame 101. A rotating shaft 602 is installed between the two bearing seats. Bearings 603 are installed at both ends of the rotating shaft 602. A rotating shaft sleeve 604 is sleeved on the two bearings 603. A soil covering wheel swing arm 605 is connected to the shaft sleeve 604. A soil covering wheel bracket 606 is installed on the soil covering wheel swing arm 605. A set of soil covering wheels is symmetrically arranged at each end of the soil covering wheel bracket 606. Each set of soil covering wheels consists of two symmetrically arranged soil covering wheels 607 that are inclined inwards towards each other.

[0023] The working principle of the above embodiments is as follows: In operation, two operators sit in their respective seats 106. Using various control levers on the control console 209, the operators can control the transplanter to start, stop, turn right, and turn left via the drive mechanism 2. They can also shift gears by operating the first gear lever 207 and the second gear lever 208 as needed. After the transplanter starts, the generator 302 in the power unit 3 supplies power to the electrical control box 301 and the air compressor 303. The electrical control box 301 provides power to the track gearbox 202, which in turn drives the gearbox shaft 203 and the drive wheel 204 to rotate simultaneously, thereby driving the track... When the belt-type chassis wheels 205 are in operation, the directional wheels 206 provide auxiliary functions to stabilize the movement of the transplanter. During the movement of the transplanter, the electrical control box 301 also provides power to the seedling separating device 5. The reduction motor 502 drives the drive gear 510 in the gearbox 501 to rotate. The drive gear 510 drives the first driven gear 511 to rotate. The first driven gear 511 drives the second driven gear 512 to rotate. At the same time, the third sprocket assembly 509 rotates, driving the second sprocket assembly 508 to rotate. The second sprocket assembly 508 drives the first sprocket assembly 505 connected to it to rotate. When the transmission chain 506 is activated, the four first sprocket assemblies 505 rotate together, ultimately driving several first large-mouth seedling cups 507 to rotate on the wire guide rails 504. The two sets of several first large-mouth seedling cups 507 on the bottom panel 503 can simultaneously rotate on their corresponding wire guide rails 504 for manual insertion of male and female seedlings, or even the same type of seedling, offering flexibility and convenience. Workers pick up seedlings from the seedling tray 8 of the second seedling tray support 9 and insert them into the cups. The first large-mouth seedling cups 507 have a flip-top cover 510 that is initially closed, preventing the inserted seedlings from falling out. When the first large-mouth seedling cup 507 carrying the seedling rotates to the corresponding position above the second large-mouth seedling cup 410, the flip cover 510 of the first large-mouth seedling cup 507 opens, the seedling falls, passes through the second large-mouth seedling cup 410, and then enters the third large-mouth seedling cup 412. The air compressor 303 provides power to the double guide rail slide module 403, and the seedling then moves downward through the duckbill planting head 410 driven by the double guide rail slide module 403 until it is inserted into the soil and opens, planting the seedling in the soil. The duckbill planting head 410 then moves upward, thereby notifying the transplanter to continue moving forward. The soil covering wheel 607 gathers the soil around the seedling inward.

[0024] In summary, this semi-automatic special-purpose transplanter is a customized transplanting device, mainly used when different seedlings need to be transplanted simultaneously in two rows. It allows two workers to separate and place the seedlings in front of them simultaneously, followed by automatic planting. It is flexible and convenient to use, solving the technical problem that existing transplanters can only transplant the same type of seedling when transplanting two rows automatically. When different seedlings need to be transplanted in two rows at the same time, such as transplanting male seedlings on one side and female seedlings on the other, existing transplanters cannot meet the work requirements.

[0025] In addition, the semi-automatic special transplanter has a set of first seedling tray support brackets 7 symmetrically set on both sides of the equipment, on which at least three rows of seedling trays 8 are placed, with at least six on each side. This allows for convenient replacement of empty seedling trays 8 with seedling trays 8 filled with seedlings during the transplanting process, thus improving work efficiency.
