Description

Technical Field

[0001] This utility model relates to the field of seedling conveying technology, specifically a raw material seedling chain conveying mechanism. Background Technology

[0002] Currently, fully automatic plug seedling transplanters have been industrialized and applied abroad. Some vegetable and flower companies or planting bases have imported advanced plug seedling transplanters from abroad, but there are problems such as high cost, unsuitability for domestic planting models, and inconvenient after-sales service.

[0003] During the cultivation, transportation, and transplanting of plug seedlings, seedlings may exhibit poor development, disease, or death. In fully automated transplanting, seedling retrieval failures may occur. If weak, diseased, dead, and empty seedlings in the plug trays are not inspected and replanted before automated transplanting, the subsequent seedling retrieval claws may fail to retrieve seedlings from the plug trays, or the retrieved seedlings may have a low survival rate after transplanting, severely reducing the overall success rate of automated transplanting. The intermittent feeding accuracy and conveying method of existing plug tray conveyor lines are insufficient to meet the seedling retrieval and replanting needs of the fully automated seedling retrieval claw assembly, significantly reducing the accuracy of seedling retrieval and replanting, and overall work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a raw material seedling chain conveying mechanism, which solves the problems of intermittent feeding accuracy and seedling conveying method in existing seedling tray conveying lines, which are difficult to meet the seedling picking and refilling actions of fully automatic seedling picking gripper components, thus significantly reducing the accuracy of seedling picking and refilling and the overall work efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A raw material seedling chain conveying mechanism includes a support frame and a sprocket and chain mechanism disposed between the support frames. A power box is provided on one side of the sprocket and chain mechanism. Multiple push rods are arranged between each pair of chains on the sprocket and chain mechanism. A support plate is fixedly installed on the support frame. Driven by the chain, the push rods push the raw material seedling trays located on the support plate to move along the length of the support plate. Positioning photoelectric switches are symmetrically arranged on the sides of the support frame to cooperate with the power box to control the sprocket and chain mechanism to drive the push rods to intermittently feed the raw material seedling trays. A pressure plate assembly is provided above the raw material seedling trays on the support frame to limit and compress the upper surface of the raw material seedling trays during intermittent feeding.

[0009] Preferably, limiting plates are symmetrically arranged on the support frame, the limiting plates are located on both sides of the support plate, and a trapezoidal area is formed between one end of the two limiting plates, with the open part of the trapezoidal area away from the power box.

[0013] (III) Beneficial Effects

[0014] This utility model has the following beneficial effects:

[0015] This raw material seedling chain conveying mechanism, through the set sprocket chain mechanism and push rod, can form a chain circulation mechanism, which can push the raw material seedling tray falling into the support plate to move along a predetermined direction. Due to the arrangement of positioning photoelectric switches, it can cooperate with the control system to control the start and stop of the drive motor in the power box, so that the push rod can drive the raw material seedling tray to move a preset distance at a time, so as to quickly cooperate with the automatic seedling picking claw assembly to quickly pick up the seedlings in a single row of the raw material seedling tray.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This utility model provides a technical solution: a raw material seedling chain conveying mechanism, including a support frame 1 and a sprocket and chain mechanism 4 disposed between the support frames 1. A power box 3 is provided on one side of the sprocket and chain mechanism 4. Multiple push rods 5 are arranged on the sprocket and chain mechanism 4 between the chains. A support plate 2 is fixedly disposed on the support frame 1. The push rods 5, driven by the chain, push the raw material seedling trays located on the support plate 2 to move along the length direction of the support plate 2. Positioning photoelectric switches 10 are symmetrically disposed on the side of the support frame 1 to cooperate with the power box 3 to control the sprocket and chain mechanism 4 to drive the push rods 5 to push the raw material seedling trays to feed intermittently. A pressure plate assembly 7 is disposed above the raw material seedling trays on the support frame 1 to limit and squeeze the upper surface of the raw material seedling trays when they are intermittently fed.

[0023] This invention, through the sprocket and chain mechanism 4 and the push rod 5, can form a chain circulation mechanism, which can then push the seedling tray falling onto the support plate 2 to move along a predetermined direction. Due to the positioning photoelectric switch 10, it can cooperate with the control system to control the start and stop of the drive motor in the power box 3, thereby causing the push rod 5 to move the seedling tray a preset distance at a time, so as to quickly cooperate with the automatic seedling picking claw assembly to quickly pick up seedlings from a single row of seedlings in the seedling tray.

[0024] Reference Figure 1 and 2 As shown, in this embodiment, limiting plates 6 are symmetrically arranged on the support frame 1. The limiting plates 6 are located on both sides of the support plate 2, and a trapezoidal area is formed between one end of the two limiting plates 6. The open part of the trapezoidal area is away from the power box 3. By setting the limiting plates 6, the feeder tray can be moved on the support plate 2 by the push rod 5, effectively limiting the displacement of the tray along the width direction of the support plate 2, ensuring that the feeder tray moves accurately to the preset stop position, and avoiding the situation where the subsequent seedling clamp is not accurately positioned due to the tilt of the tray during the movement. The trapezoidal area formed between one end of the two limiting plates 6 can facilitate the quick guidance of the tray into the space between the limiting plates 6, so that the parallel area of ​​the limiting plates 6 can stably limit the feeder tray.

[0025] In this embodiment, a mounting rail 8 is fixedly provided on the outer side of the support frame 1, and a mounting bracket 9 is fixedly connected to the mounting rail 8. The positioning photoelectric switch 10 is detachably mounted on the mounting bracket 9.

[0026] Reference Figure 3 and 4 As shown, in this embodiment, the pressing plate assembly 7 includes a pressing plate frame 73, and a connecting frame 71 is fixedly connected to the mounting guide rail 8. Multiple pressing plate frames 73 are detachably installed on the connecting frame 71 at equal intervals. By setting multiple pressing plate frames 73, multiple points on the end face of the seedling tray can be pressed, preventing elastic deformation of the tray under the pressure of the limiting plate 6, which would cause some holes to protrude upwards, thus changing the position of the seedlings in a single row of holes. This would cause the seedling picking position of the subsequent seedling picking claw to shift, leading to seedling picking failure or damage to the seedlings.

[0027] Reference Figure 4 As shown, in this embodiment, an adjustment groove 72 is arranged through the connecting frame 71, and the pressure plate 73 is pressed and fixed to the connecting frame 71 by fasteners passing through the adjustment groove 72. The adjustment groove 72 allows for easy adjustment of the spacing between the various pressure plate 73 as needed, thereby adapting to the application requirements of different types of pressure plates.
