Description

Technical Field

[0001] The utility model belongs to the technical field of palletizing machines, and particularly relates to a disk separating wheel, a disk separating device and an automatic seedling tray palletizing machine for rice seedlings. Background Art

[0002] In the traditional automatic rice seedling raising process, it is necessary to place the seedling trays in a rice seeding machine. The soil is spread in the seedling trays by the rice seeding machine, and then the rice seeds are sown in the seedling trays, and operations such as watering are carried out. During sowing, it is necessary to place the individual seedling trays in the rice seeding machine one by one for operation. Since the seedling trays are stacked vertically in the production and transportation process, multiple seedling trays are stacked vertically to form a seedling tray stack; however, before sowing, it is necessary to remove the seedling trays from the seedling tray stack one by one and send the individual seedling trays into the rice seeding machine in sequence. When the existing seedling tray separating device separates the seedling trays, adjacent seedling trays may be adsorbed together due to long-term extrusion, and it is difficult for the separating device to separate the seedling trays one by one, resulting in multiple seedling trays being sent into the rice seeding machine at the same time, causing great difficulties in the seedling tray separation work. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a disk separating wheel, a disk separating device and an automatic seedling tray palletizing machine for rice seedlings, so as to solve the problem that it is difficult to separate the seedling trays in the seedling tray stack because they are attached to each other.

[0004] The utility model is realized by the following technical solutions:

[0005] The disk separating wheel includes a columnar body and a row of disk spirals spirally arranged along the axial direction of the body on the outer circumference of the body. When the row of disk spirals extends into the groove provided on the side edge of the seedling tray, the row of disk spirals can support the seedling tray at the corresponding position through the cooperation with the flange on the side edge of the seedling tray.

[0006] The tooth surface of the row of disk spirals is provided with a disk separating unit. When the disk separating unit moves between two adjacent seedling trays in the seedling tray stack, it can apply opposite acting forces along the stacking direction of the seedling tray stack to the two adjacent seedling trays, so that the two adjacent seedling trays are separated.

[0007] In some embodiments, the disk separating unit includes a convex platform arranged above the tooth surface of the starting section of the row of disk spirals. Along the downward spiral direction, the upper end surface of the convex platform is a first gradually changing slope surface with an increasing distance from the tooth surface of the starting section.

[0008] When the convex platform moves between two adjacent seedling trays and the upper end surface of the convex platform contacts the flange of the seedling tray above it at the highest point position, the distance between the contact position of the row of trays helix and the upper end surface of another seedling tray and the highest point position of the upper end surface of the convex platform in the axial direction of the body is greater than the distance between the lower end surface of the flange of the seedling tray and the upper end surface of the adjacent seedling tray.

[0009] In some embodiments, along the downward spiral direction, the upper end surface of the convex platform further includes a second gradually changing slope surface whose distance from the tooth surface of the starting section gradually decreases starting from the highest point position of the upper end surface of the convex platform.

[0010] In some embodiments, the tray separating unit includes a wedge-shaped member disposed below the tooth surface of the separating section of the row of trays helix. Along the downward spiral direction, the lower end surface of the wedge-shaped member is a third gradually changing slope surface whose distance from the tooth surface of the separating section gradually increases;

[0011] When the wedge-shaped member moves between two adjacent seedling trays, the tooth surface of the separating section provides support for the seedling tray above, and the lower end surface of the wedge-shaped member can provide a separating force for the seedling tray below to separate it from the seedling tray above and separate it from the tray separating wheel.

[0012] In some embodiments, the end of the starting end of the row of trays helix is provided with a transition end surface inclined downward.

[0013] A tray separating device includes a plurality of the above-mentioned tray separating wheels, and enables the row of trays helixes of each tray separating wheel to support the seedling trays at different positions.

[0014] In some embodiments, the tray separating device includes:

[0015] A mounting frame, and the tray separating wheels are respectively rotatably arranged on the mounting frame in the vertical direction, so that the tray separating wheels can rotate on the mounting frame along the axis of the body;

[0016] A driving assembly, and the driving assembly is used to drive each tray separating wheel to rotate.

[0017] In some embodiments, four tray separating wheels are arranged on the mounting frame, and the tray separating wheels are symmetrically arranged relative to each other on the mounting frame and are distributed in a rectangle matching the seedling trays.

[0018] An automatic seedling tray rowing machine adopts the above-mentioned tray separating device.

[0019] In some embodiments, it includes a conveying device, and the conveying device is arranged below the tray separating device and is used to convey the single seedling trays separated by the tray separating device.

[0020] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0021] As the dividing wheel rotates, the stack of seedling trays arranged on the tray-arranging spiral moves downward under the action of the tray-arranging spiral in the vertical direction. When the dividing unit moves between two adjacent seedling trays in the stack of seedling trays, it can apply acting forces with opposite directions along the stacking direction of the stack of seedling trays to the two adjacent seedling trays. While driving the stack of seedling trays, it promotes the separation of two adjacent seedling trays. In this way, when the seedling tray at the bottom of the stack of seedling trays is separated from the tray-arranging spiral, the seedling tray can be smoothly separated from the stack of seedling trays, which well solves the problem caused by the sticking and jamming between the seedling trays in the stack of seedling trays and the difficulty in effective separation.

Detailed Embodiments

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figures 1 to 4 As shown, the tray sorting wheel includes a columnar body 3 and a tray sorting helix 4 spirally arranged along the axial direction of the body 3 on the outer circumference of the body 3. When the tray sorting helix 4 extends into the groove provided on the side edge of the seedling-raising tray 1, the tray sorting helix 4 can support the seedling-raising tray 1 at the corresponding position through cooperation with the flange 27 on the side edge of the seedling-raising tray 1;

[0032] A tray sorting unit is provided on the tooth surface of the tray sorting helix 4. When the tray sorting unit moves between two adjacent seedling-raising trays 1 in the seedling-raising tray stack, it can apply acting forces in opposite directions along the stacking direction of the seedling-raising tray stack to the two adjacent seedling-raising trays 1, causing the two adjacent seedling-raising trays 1 to separate.

[0033] In this embodiment, as the tray sorting wheel 5 rotates, the stack of seedling-raising trays 1 provided on the tray sorting helix 4 moves downward under the action of the tray sorting helix 4 in the vertical direction. When the tray sorting unit moves between two adjacent seedling-raising trays 1 in the seedling-raising tray stack, it can apply acting forces in opposite directions along the stacking direction of the seedling-raising tray stack. While driving the seedling-raising tray stack, it promotes the separation of two adjacent seedling-raising trays 1. In this way, when the seedling-raising tray 1 at the bottom of the seedling-raising tray stack separates from the tray sorting helix 4, the seedling-raising tray 1 can smoothly separate from the seedling-raising tray stack, which well solves the problem caused by the sticking and jamming between the seedling-raising trays 1 in the seedling-raising tray stack and the difficulty in effective separation.

[0034] In some embodiments, the tray sorting unit includes a boss 31 provided above the tooth surface of the starting section 41 of the tray sorting helix 4. Along the downward spiral direction, the upper end surface of the boss 31 is a first gradually changing slope surface 51 with an increasing distance from the tooth surface of the starting section 41. Along the downward spiral direction, the upper end surface of the boss 31 further includes a second gradually changing slope surface 52 with a decreasing distance from the tooth surface of the starting section 41 starting from the highest point position of the upper end surface of the boss 31.

[0035] When the boss 31 moves between two adjacent seedling trays 1 and the upper end surface of the boss 31 is at its highest point and contacts the flange 27 of the seedling tray 1 above it, the distance between the contact position of the row of trays spiral 4 and the upper end surface of another seedling tray 1 and the highest point position of the upper end surface of the boss 31 in the axial direction of the body 3 is greater than the distance between the lower end surface of the flange 27 of the seedling tray 1 and the upper end surface of the adjacent seedling tray 1. During the process that the flange 27 of the upper seedling tray 1 in the mutually attached seedling trays 1 moves to the top of the boss 31 as the row of trays spiral 4 rotates, the upper top surface of the lower seedling tray 1 abuts against the bottom surface of the boss 31 on the row of trays spiral 4. When the flange 27 of the upper seedling tray 1 continues to rotate with the row of trays spiral 4 and slides to the top of the boss 31, under the limit of the bottom surface of the boss 31, a separating force will be generated between the lower seedling tray 1 and the upper seedling tray 1, enabling the mutually attached seedling trays 1 to be separated once. When the stack of seedling trays is driven by the row of trays spiral 4, the seedling tray 1 at the bottom of the stack of seedling trays can be easily separated from other seedling trays 1 and fall off.

[0036] In some embodiments, a transition end face 33 inclined downward is provided at the end of the starting end of the row of trays spiral 4, enabling the row of trays spiral 4 to better enter between the two seedling trays 1.

[0037] Embodiment 2

[0038] As Figure 1 and Figure 3 shown, the tray separating unit includes a wedge 32 provided below the tooth surface of the separating section 42 of the row of trays spiral 4. Along the downward spiral direction, the lower end surface of the wedge 32 is a third gradually changing slope surface 53 with an increasing distance from the tooth surface of the separating section 42.

[0039] When the wedge 32 moves between two adjacent seedling trays 1, the tooth surface of the separating section 42 provides support for the upper seedling tray 1, and the lower end surface of the wedge 32 can provide a separating force for the lower seedling tray 1 to separate it from the upper seedling tray 1 and from the tray separating wheel 5.

[0040] Embodiment 3

[0041] As Figures 1 to 3 shown, this embodiment combines Embodiment 1 and Embodiment 2. The tray separating unit includes an arched boss 31 and a wedge 32. Under the combined action of the boss 31 and the wedge 32, the mutually attached seedling trays 1 can be separated. When the stack of seedling trays is driven by the row of trays spiral 4, the seedling tray 1 at the bottom of the stack of seedling trays can be easily separated from other seedling trays 1 and fall off.

[0042] Embodiment 4

[0043] The tray-sorting device, as Figure 5 shown, includes a plurality of tray-sorting wheels 5 in the above embodiments, and enables the row-forming spirals 4 of each tray-sorting wheel 5 to support the seedling-raising trays 1 at different positions.

[0044] The tray-sorting device includes:

[0045] An installation frame 2, on which the tray-sorting wheels 5 are respectively rotatably arranged in the vertical direction, so that the tray-sorting wheels 5 can rotate along the axis of the main body 3 on the installation frame 2;

[0046] A driving assembly, which is used to drive the rotation of each tray-sorting wheel 5, transmit the stack of seedling-raising trays placed overlapping in the vertical direction downward as a whole, and under the action of the tray-sorting unit, separate two adjacent seedling-raising trays 1.

[0047] In some embodiments, four tray-sorting wheels 5 are arranged on the installation frame 2, and the tray-sorting wheels 5 are symmetrically arranged relative to each other on the installation frame 2 and are distributed in a rectangle matching the seedling-raising trays 1.

[0048] Embodiment 5

[0049] The automatic seedling-raising tray row-forming machine, as Figure 5 shown, adopts the tray-sorting device in the above embodiment.

[0051] The working principle of this embodiment is as follows: The staff places the stack of seedling-raising trays at the corresponding position of the tray-sorting device 6 and starts the tray-sorting device 6. At this time, the tray-sorting wheels 5 start to rotate, and the stack of seedling-raising trays is transmitted downward along with the row-forming spirals 4 on the tray-sorting wheels 5. During the process of the stack of seedling-raising trays being transmitted downward as a whole, when the tray-sorting unit on the row-forming spiral 4 moves between two adjacent seedling-raising trays 1 in the stack of seedling-raising trays, it can apply opposite acting forces along the stacking direction of the stack of seedling-raising trays to the two adjacent seedling-raising trays 1, and the two adjacent seedling-raising trays 1 are separated, so that the seedling-raising tray 1 at the bottom of the stack of seedling-raising trays can be easily separated from other seedling-raising trays 1 and fall off.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0053] In addition, in the description of the present utility model, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
