Description

Technical Field

[0001] The invention relates to agricultural seedling raising and transplanting technology, in particular to a transplanting machine which has stable movement and can automatically take and drop seedlings, and an automatic seedling taking device thereof. Background Art

[0002] Seedling transplanting technology can shorten the production cycle, improve crop survival rate and multiple cropping index, and increase economic benefits. At present, most transplanting is done by semi-automatic transplanters: semi-automatic transplanting limits transplanting efficiency and has high labor intensity, which is not suitable for large-scale operations and hinders the development of large-scale production; semi-automatic transplanting requires manual removal of seedlings from pots and placing them in corresponding conveying devices or directly sending them into planting devices. Due to the limited speed of manual seedling feeding and the large number of operators, the operating efficiency is not high, which is not suitable for completing large-scale transplanting in a short period of time, and the mechanization benefits are not obvious; in addition, in some areas with a small population and a large planting area, the shortage of labor makes it difficult to promote semi-automatic transplanting. In addition, transplanting and drip irrigation technology are used together, which requires the rapid completion of the transplanting operation of the entire strip field, which puts higher requirements on the speed of the transplanter. Semi-automatic transplanters are limited by the speed of manual seedling throwing, have low work efficiency, and have no obvious economic benefits, so they have been difficult to promote on a large scale.

The seedling feeding mechanism 2 feeds the seedling tray row by row intermittently, and the seedling pushing mechanism 7 pushes out the seedlings to be taken above and separates the seedlings from the seedling tray; the seedling taking mechanism 3 reaches the seedling clamping position to clamp the matrix part of the pushed-out seedlings, and the seedling pushing mechanism 7 retracts at the same time; the seedling taking mechanism 3 clamps the seedlings and moves to the top of the seedling separation mechanism 4 and throws them out, and the seedlings fall into the seedling separation mechanism 4 and fall into the planting mechanism 6 one by one, and the planting mechanism 6 completes the seedling planting.

[0077] See also Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of a seedling taking mechanism 3 according to an embodiment of the present invention. Figure 4 for Figure 3The seedling taking mechanism 3 of this embodiment comprises: a non-circular gear box 31, which is mounted on the frame 1 through a support seat; a square shaft 36, one end of which is coaxially connected to the planetary gear shaft of the non-circular gear box 31, and the other end of the square shaft 36 is connected to another support seat; a push rod 34, which is parallelly mounted on the square shaft 36 and slides back and forth along the axial direction of the planetary gear of the non-circular gear box 31; a plurality of baffles 341 and push rod tension springs 342 are provided on the push rod 34, and the baffles 341 are always in contact with the seedling claw opening and closing roller 353, thereby driving the seedling claw 35 2 is opened or closed; one end of the push rod tension spring 342 is connected to the push rod 34, and the other end of the push rod tension spring 342 is fixedly connected to the square shaft 36; the seedling clamping cam 32 is fixedly installed on the outside of the non-circular gear box 31 by bolt connection; the seedling clamping roller 33 is installed and fixed at the end of the push rod 34 and contacts the seedling clamping cam 32; and the seedling claw component 35 is installed on the square shaft 36 and connected to the baffle 341 of the push rod 34. The seedling claw component 35 changes its posture with the swing of the non-circular gear box 31 to achieve seedling removal and seedling casting.

[0078] See also Figure 5 , Figure 5 The schematic diagram of the structure of the seedling claw component 35 of one embodiment of the present invention. The seedling claw component 35 of this embodiment includes: a seedling claw fixing seat 351, which is installed on the square shaft 36; a seedling claw opening and closing roller 353, which is installed on the seedling claw fixing seat 351 and abuts against the baffle 341 of the push rod 34; a seedling claw 352, the top of which is connected to the seedling claw opening and closing roller 353; and a seedling claw tension spring 354, which is installed below the seedling claw fixing seat 351, and the two ends of the seedling claw tension spring 354 are respectively connected to the seedling claw 352. When the non-circular gear box 31 rotates, the seedling clamping roller 33 and the seedling claw 352 rotate with the planetary gear shaft driven by the square shaft 36. When the seedling clamping roller 33 contacts the high point of the seedling clamping cam 32, the push rod 34 slides away from the non-circular gear box 31, and the seedling claw 352 closes. When the seedling clamping roller 33 contacts the low point of the seedling clamping cam 32, the push rod 34 slides toward the non-circular gear box 31 under the action of the push rod tension spring 342, and the seedling claw 352 opens under the action of the seedling claw tension spring 354. In this process, the seedling claw 352 changes its posture with the swing of the non-circular gear box 31, meeting the requirements of seedling removal and seedling throwing operations.

[0079] See also Figure 6 , Figure 6The structure of the seedling separation mechanism 4 of one embodiment of the present invention is schematically shown. In this embodiment, the seedling separation mechanism 4 includes: a seedling separation cylinder 46, which is arranged below the seedling claw component 35; a swinging seedling receiving plate 41, which is arranged at the entrance of the seedling separation cylinder 46; a swinging cam 43, which is connected to the swinging seedling receiving plate 41 through a swinging pull rod 44, and the upper end of the swinging pull rod 44 is connected to the swinging seedling receiving plate 41 through a connecting rod; a swinging roller is arranged at the lower end of the swinging pull rod 44, and the swinging roller is always in contact with the swinging cam 43; the swinging pull rod 44 drives the swinging seedling receiving plate 41 to swing left and right, respectively adapting to the seedlings in different positions; a seedling separation cam 42, which is arranged below the swinging seedling receiving plate 41, and is used to make the seedlings falling into the seedling separation cylinder 46 fall one by one; and a seedling drop port 45, which is arranged at the exit of the seedling separation cylinder 46, so that the seedlings falling one by one fall into the planting mechanism 6. Among them, the swing roller is in contact with the swing cam 43 through a tension spring. Under the action of the tension spring, when the swing roller contacts the high point of the swing cam 43, the upper end of the swing pull rod 44 swings to the right, driving the swing grafting plate 41 to swing to the right; when the swing roller contacts the low point of the swing cam 43, the upper end of the swing pull rod 44 swings to the left, driving the swing grafting plate 41 to swing to the left.

[0080] See also Figure 7 , Figure 7 The structure diagram of the seedling pushing mechanism 7 of one embodiment of the present invention is shown in FIG. The seedling pushing mechanism 7 of this embodiment includes a bracket, a cylinder 71 and a seedling pushing rod 72, wherein the seedling pushing rod 72 is mounted on the bracket, the cylinder 71 is connected to the bracket, and the seedling pushing rod 72 is arranged corresponding to the seedling tray of the seedling delivery mechanism 2. When the seedling delivery mechanism 2 delivers the seedling tray to the seedling removal position, the cylinder 71 drives the seedling pushing rod 72 to push the seedling out of the hole tray. The seedling pushing mechanism 7 may include two groups of cylinders 71 and seedling pushing rods 72, which respectively act to push out the entire row of seedlings to be removed at two intervals.

[0081] During operation, since the spacing between seedlings in the seedling tray is small, in order to ensure sufficient space for taking seedlings, the seedlings are taken out at intervals when taking seedlings once. The seedling lifting mechanism 7 and the seedling taking mechanism 3 are respectively composed of two groups of working parts, which cooperate to complete the seedling taking operation of the whole row of seedlings. The seedling separation mechanism 4 swings left and right by swinging the seedling receiving plate 41 to adapt to the seedling throwing work at different positions. The seedling feeding mechanism 2 intermittently feeds the seedling tray row by row so that the seedling lifting rod 72 is right to the seedling to be taken. The seedling lifting rod 72 is pushed upward under the action of the cylinder 71. The ejector of the seedling lifting rod 72 is inserted into the seedling matrix, and the seedling is separated from the seedling tray under the action of the ejector rod of the seedling lifting rod 72. At this time, the seedling claw 352 reaches the seedling clamping position under the drive of the non-circular gear box 31 to clamp the matrix part of the seedling being ejected, and the seedling lifting rod 72 retracts at the same time. The seedling claw 352 clamps the seedling and moves to the top of the seedling separation mechanism 4 and throws it out, and the seedling falls into the seedling separation tube 46 and falls one by one under the action of the seedling separation cam 42, and falls into the planting mechanism 6.

[0082] The present invention can efficiently complete the automatic transplanting of crops. When working, there are two working modes: clamping stems (seedling claws 352 working alone) and clamping substrates (seedling top stem 72-seedling claws 352 working in combination), which can be applied to leafy vegetables and eggplant vegetables. The rotary seedling picking mechanism 3 and the staggered arrangement of seedling picking claws 352 are combined with a swinging seedling guide tube to increase the seedling picking speed, eliminate the lateral movement of the seedling tray, and ensure stable operation under high-speed operation. The labor intensity is reduced, the transplanting efficiency is improved, and the large-scale promotion and use of transplanters can be effectively promoted.

[0083] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
