Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a tray distribution device and a tray supply device. Background Technology

[0002] Some crops require seedling raising before cultivation. Traditional seedling raising methods typically involve a large amount of manual labor, such as sowing, covering with soil, and watering. This is not only time-consuming and labor-intensive but also easily affected by weather and human factors, leading to unstable seedling raising results. With technological advancements, mechanized seedling raising and sowing technologies have emerged to address the problems of low efficiency, high labor intensity, and unstable seedling quality associated with traditional methods. Currently, mechanized seedling raising requires manual placement of stacked seedling trays one by one, which is extremely tedious. Therefore, it is crucial to develop a tray-separating device and a tray-feeding device that can disassemble stacked seedling trays one by one. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, on the one hand, the present invention provides a tray separating device, including at least two claws, the two claws being arranged opposite to each other; each claw is provided with a first rotating shaft, the opposing claws rotating upward about the first rotating shaft as a baseline to lift the tray stacked on top, so as to separate it from the tray below, and the claws rotating downward about the first rotating shaft as a baseline to place the tray on the placement surface.

[0004] The disc dividing device includes two sets of disc dividing assemblies arranged opposite each other. Each disc dividing assembly includes a swing shaft, the axis of which forms the first rotating shaft. At least one of the chucks is located on the swing shaft and rotates with the swing shaft.

[0005] The disc assembly also includes a connecting rod, which moves up and down to control the rotation of the swing shaft. The connecting rod is rotatably connected to a first connecting member, which is positioned on the swing shaft. Moving the connecting rod up and down controls the rotation of the first connecting member, thereby controlling the rotation of the swing shaft.

[0006] It also includes a drive device, which includes a motor. The output shaft of the motor drives an RV reducer. The double-headed output shaft of the RV reducer is connected to a connecting rod via an eccentric shaft. The connecting rod and the eccentric shaft are rotatably connected. The eccentric shaft rotates eccentrically, thereby controlling the up and down movement of the connecting rod.

[0007] The claw includes a fixed bracket that is limited by the first rotating shaft and an adjustable bracket that is slidably and adjustablely connected to the fixed bracket. The adjustable bracket is at least partially provided with a hook for supporting the disc.

[0008] A rotating bearing is connected to the adjusting bracket; an adjusting bolt is installed on the fixed bracket, passing through the adjusting bracket, and a spring is sleeved on the adjusting bolt between the adjusting bracket and the fixed bracket; the adjusting bracket and the fixed bracket are respectively provided with adjusting rails and limiting grooves, and the adjusting fastener passes through the limiting groove and adjusting rail and locks in place to achieve the adjustment limit, so as to adapt to different sizes of seedling trays. Minor changes caused by the aging and wear of the seedling tray itself can be offset by the bearing and spring.

[0009] Two claws are fixedly installed on each of the above-mentioned swing arms, and the two claws are symmetrically arranged with the same spacing. Alternatively, the spacing can be made inconsistent depending on the actual shape of the disc.

[0010] Through the above technical solution, this utility model can lift the stacked seedling trays, leaving only the bottom seedling tray on the placement surface of the main transmission component, and drive the motor to work so that the seedling tray moves forward to achieve tray feeding.

[0011] On the other hand, the present invention provides a tray feeding device, including a tray splitting mechanism, a main conveying mechanism and a spare tray conveying mechanism. The tray splitting mechanism includes at least one of the above-mentioned tray splitting devices, and the main conveying mechanism and the spare tray conveying mechanism are respectively disposed on both sides of the tray splitting mechanism.

[0012] It also includes a rack on which a plurality of main conveying components are provided, at least some of which are located below the tray distribution device to form the placement surface.

[0013] The frame is also provided with several spare conveying components, which are configured on the spare tray conveying mechanism; a support column is fixed on the frame, and a first proximity switch and a second proximity switch with a gap are provided on the support column in the longitudinal direction; a sensing plate is fixed on the swing shaft of the tray separating device to change the signals of the first proximity switch and the second proximity switch.

[0014] A guide plate is mounted on the frame; an electrical control box is also mounted on the frame. The swing arm is rotatably connected to a fixed support column via a bearing.

[0015] The aforementioned guide plate design allows the seed tray to be positioned in the center of the tray for smooth transport. The guide plate of this invention can be adjusted via adjustment holes to accommodate seed trays of different sizes.

[0016] Both the main transmission assembly and the backup transmission assembly include: a main drive shaft, a driven shaft and a transmission belt connecting the two, and a drive motor. The drive motor is mounted on the frame, the main drive shaft is rotatably connected to the frame, a sprocket is fixed on the main drive shaft, and a drive sprocket is fixed on the output shaft of the drive motor. The drive sprocket and the sprocket are driven by a chain.

[0017] The drive shaft is connected to the frame via a connecting plate, and the drive shaft and the connecting plate are rotatably connected. The frame is provided with a slide rail, and the connecting plate is disposed on the slide rail. A screw is threadedly connected to the frame, and a slot adapted to the screw is provided on the connecting plate. One end of the screw is inserted into the slot to adjust the position of the connecting plate on the frame. Seedling tray induction plates are rotatably connected to the frame at the main conveying assembly and the backup conveying assembly.

[0018] The aforementioned main conveying assembly and backup conveying assembly are detachably connected to the frame via connecting plates, allowing for quick assembly and disassembly and length adjustment as needed. Furthermore, the tray-separating mechanism of this invention can be used independently or in conjunction with the backup tray conveying mechanism, making its application more flexible. The electrical control box includes a control board, a seedling tray induction board, a first induction switch, and a second induction switch electrically connected to the input terminal of the control board. The output terminal of the control board is electrically connected to a drive motor and a motor.

[0019] Through the above technical solution, this utility model adds a spare tray conveying mechanism, which can promptly replace the seedling trays stacked on the tray distribution mechanism after they have been used up, preventing missed supply and increasing the system's fault tolerance.

[0020] The extended conveyor line of the backup conveyor allows for the storage of more seedling trays, reducing labor intensity and improving efficiency.

[0021] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, uses mechanization to reduce labor intensity, and has the advantages of saving labor and time, high efficiency, and good quality.

[0022] When the seedling tray sensor plate of the main conveying mechanism fails to detect the seedlings, the tray on the backup conveying mechanism will be activated for use. Attached Figure Description

It should be noted that the following are only some specific embodiments of the present utility model concept, and are only a part of the embodiments of this utility model. The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.

[0042] Through the above technical solution, this utility model adds a spare tray conveying mechanism 10, which can promptly replace the seedling trays 16 stacked on the tray-dividing mechanism 8 after they have been used up, preventing the occurrence of missed supply and increasing the fault tolerance of the system.

[0048] A longitudinal support is fixed to the back of the longitudinal frame or electrical control box. A rotating shaft connects to a sensor plate with the same structure as the aforementioned sensor plate. This support is used to accept the height of stacked seedling trays. When there are enough seedling trays, the sensor plate is compressed. If there are not enough seedling trays, the sensor plate at that location springs up, and the third sensor that works with it will also spring up. Figure 8 SQ1 is used to refer to the middle.
