Description

Technical Field

[0001] This utility model relates to the field of waste seedling conveying technology, specifically a waste seedling receiving and conveying mechanism. Background Technology

[0002] Currently, fully automatic plug seedling transplanters are already industrially used abroad, and some vegetable and flower companies or planting bases have imported advanced plug seedling transplanters from overseas. However, these machines suffer from high costs, unsuitability for domestic planting methods, and inconvenient after-sales service. Domestic research on plug seedling technology is relatively recent and lags behind mature international technologies. Currently, semi-automatic plug seedling transplanters requiring manual feeding are widely used in China, but fully automatic plug seedling transplanters suitable for field operations and eliminating the need for manual seedling handling are less common. Domestic crop transplanting is mostly done manually or with semi-automatic transplanters requiring manual feeding. Semi-automatic transplanters are labor-intensive, inefficient, and costly, making them unsuitable for greenhouse agriculture transplanting operations.

[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 and low seedling survival rates after transplanting can occur. Therefore, before automated transplanting, it is necessary to inspect the plug trays for weak, diseased, dead, and empty seedlings, and then replant healthy seedlings to create qualified finished seedling plug trays. Before replanting, weak, diseased, and dead seedlings need to be removed from the plug trays and transported out of the automated transplanting machine. Current technology typically uses a seedling retrieval gripper assembly with a three-axis motion module for this operation. However, this method involves too many actions, resulting in low efficiency and high overall investment and maintenance costs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a waste seedling receiving and conveying mechanism, which solves the problems of excessive actions required for removing and discharging waste seedlings from seed trays in existing fully automatic transplanting machines, resulting in low efficiency in waste seedling removal and discharge, as well as high overall investment and maintenance costs.

[0006] (II) Technical Solution

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

[0008] A waste seedling receiving and conveying mechanism includes a conveyor belt assembly. A drive module is provided on one side of the conveyor belt assembly. An extension frame is fixedly connected to the conveyor belt assembly. A drive cylinder is rotatably connected to the extension frame. A connecting member is fixedly connected to the piston end of the drive cylinder. A cooperating rod is rotatably connected to the connecting member. A receiving plate is fixedly connected to the cooperating rod. The receiving plate is rotatably arranged between the extension frames. After the dual-axis seedling gripper assembly clamps the waste seedlings and resets them to the initial position, the receiving plate rotates from the initial position to the receiving position under the drive of the drive cylinder. Waste seedlings sliding off the receiving plate fall onto the conveyor belt assembly.

[0009] Preferably, the lower end face of the conveyor belt assembly is fixedly connected to the mounting frame via symmetrically arranged mounting brackets.

[0010] Preferably, the receiving plate has rolled edges on both sides, and the length of the receiving plate supports the simultaneous placement of waste seedlings by all the gripper assemblies on the dual-axis seedling picking gripper assembly.

[0011] Preferably, an extension plate is fixedly disposed between the extension frames, and the extension plate is obliquely arranged above the conveyor belt assembly.

[0012] Preferably, a solenoid valve is installed on the end face of the extension plate, and the solenoid valve is arranged at the end of the extension plate near the drive cylinder.

[0013] (III) Beneficial Effects

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

[0015] This waste seedling receiving and conveying mechanism, through its drive cylinder and receiving plate, can replace the axial moving module on the traditional seedling gripper assembly. This allows the seedling gripper assembly to only perform movement in the Z-axis direction, effectively reducing the travel distance and operation process of the seedling gripper assembly. At the same time, it eliminates the need for a moving module with a complex transmission structure and high cost, effectively reducing investment costs. With the drive cylinder driving the receiving plate to rotate, the receiving plate rotates to a predetermined position. When the dual-axis seedling gripper assembly unloads waste seedlings, it plays a role in smoothly guiding the waste seedlings onto the conveyor belt assembly, effectively avoiding the risk of the waste seedlings tilting left and right and falling off the side of the conveyor belt assembly due to falling vertically onto it.

[0022] 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.

[0023] Please see Figure 1 This utility model provides a technical solution: a waste seedling receiving and conveying mechanism, including a conveyor belt assembly 2, a drive module 3 is provided on one side of the conveyor belt assembly 2, an extension frame 4 is fixedly connected to the conveyor belt assembly 2, a drive cylinder 5 is rotatably connected to the extension frame 4, a connecting piece 6 is fixedly connected to the piston end of the drive cylinder 5, a cooperating rod 7 is rotatably connected to the connecting piece 6, and a receiving plate 8 is fixedly connected to the cooperating rod 7. The receiving plate 8 is rotatably arranged between the extension frames 4. After the dual-axis seedling gripper assembly clamps the waste seedlings and resets them to the initial position, the receiving plate 8 rotates from the initial position to the receiving position under the drive of the drive cylinder 5, and the waste seedlings sliding off the receiving plate 8 fall onto the conveyor belt assembly 2.

[0024] This invention, through the use of a drive cylinder 5 and a receiving plate 8, can replace an axial moving module on the traditional seedling gripper assembly. This allows the seedling gripper assembly to perform movement only in the Z-axis direction, effectively reducing the moving stroke and action process of the seedling gripper assembly. At the same time, it eliminates the need for a moving module with a complex transmission structure and high cost, effectively reducing investment costs. With the drive cylinder 5 driving the receiving plate 8 to rotate, the receiving plate 8 rotates to a predetermined position. When the dual-axis seedling gripper assembly discharges waste seedlings, it plays a role in smoothly guiding the waste seedlings onto the conveyor belt assembly 2, effectively avoiding the risk of waste seedlings falling sideways and off the side of the conveyor belt assembly 2 due to falling vertically onto it.

[0025] In this embodiment, the lower end face of the conveyor belt assembly 2 is fixedly connected to the mounting frame through symmetrically arranged mounting brackets 1.

[0026] Reference Figure 1 and 4 As shown, in this embodiment, the receiving plate 8 has rolled edges on both sides, and the length of the receiving plate 8 supports the simultaneous placement of waste seedlings by all the gripper assemblies on the dual-axis seedling-picking gripper assembly. The rolled edges on both sides of the receiving plate 8 prevent waste seedlings from sliding off the edges of the receiving plate 8 when they fall into it due to other factors causing them to tilt and slip. By controlling the length of the receiving plate 8, it supports batch discharge of waste seedlings, effectively improving the waste seedling discharge efficiency.

[0027] Reference Figure 1 and 2 As shown, in this embodiment, an extension plate 9 is fixedly installed between the extension frames 4, and the extension plate 9 is inclinedly arranged above the conveyor belt assembly 2. Through the installation of the extension plate 9, the extension plate 9 can cooperate with the receiving plate 8 to form a receiving channel, thereby ensuring that after the waste seedlings fall onto the receiving plate 8, the waste seedlings can stably slide down along the receiving channel onto the conveyor belt assembly 2.

[0028] Meanwhile, the extension plate 9 can prevent waste material on the receiving plate from being thrown out due to the rapid rotation of the receiving plate, thus playing a blocking role; and since the extension frame has a certain height, the extension plate fixed at the top of the extension frame and the other two fixed plates at the bottom form a triangular relationship, preventing the mechanism's lifespan from being affected by improper installation operations.

[0029] Reference Figure 1 and 2 As shown, in this embodiment, a solenoid valve 10 is installed on the end face of the extension plate 9, and the solenoid valve 10 is arranged at the end of the extension plate 9 near the drive cylinder 5. By setting the extension plate 9, the space above the conveyor belt assembly 2 is reasonably utilized, which facilitates the quick installation and arrangement of the solenoid valve 10 for controlling the opening and closing of the drive cylinder 5, and facilitates the daily installation and maintenance of the drive cylinder 5 and the solenoid valve 10.
