[0038] In order to make the purpose, 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 combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0039] Example 1

[0040] Reference Figures 1 to 5 , field seedling conveyor, including:

[0041] The first conveying unit 1 can be arranged across the ridges in the field to transport the rice seedling trays and rice seedlings in the field;

[0042] The second conveying unit 2 is arranged along the transmission direction of the first conveying unit 1 and the feeding end of the second conveying unit 2 is hinged to the first conveying unit 1, so that the rice trays and seedlings on the first conveying unit 1 can be conveyed to the second conveying unit 2. The second conveying unit 2 is used to convey the rice trays and seedlings to the discharge end;

[0043] The lifting unit 21 is used to drive the second conveying unit 2 to move vertically around its hinged end, and lift the discharge end of the second conveying unit 2 to a set height.

[0044] In this embodiment, the first conveying unit 1 is hingedly connected to the second conveying unit 2, and the lifting unit 21 drives the second conveying unit 2 to move in the vertical direction around its hinged end, so that it can, according to actual needs, unearthed seedlings in the seedling trays or unplant machine-transplanted seedlings through the field seedling conveyor, and can also transport empty seedling trays directly from the field back to the loading position on the transport vehicle, thereby improving the efficiency of transporting field seedling trays and seedlings and reducing labor intensity.

[0045] like Figure 1 and Figure 2 As shown, the first conveying unit 1 is composed of multiple first conveying devices spliced ​​along their transmission direction. The first conveying units 1 can be spliced ​​into different lengths according to the length of the experimental field. Connecting portions 11 are provided at both ends of the first conveying devices along their transmission direction, and the first conveying devices are spliced ​​together via the connecting portions 11. Preferably, a reinforcement member is further provided at the connection portion of the connecting portion 11. The reinforcement member can reinforce the connection portion of the first conveying devices, making the multiple first conveying devices more stable when spliced ​​together.

[0046] Baffles 3 are installed on both sides of the conveying surfaces of the first and second conveying units 1 and 2. The spacing between the baffles 3 matches the width of the seedling trays to prevent the seedling trays from falling while being conveyed on the first and second conveying units 1 and 2. The baffles 3 at the ends of the first conveying devices are flared toward their ends. The width of the flared openings is greater than the width of the seedling trays, allowing the seedling trays to pass more smoothly through the splicing points between the first conveying devices.

[0047] like Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown, the first conveying unit 1 includes a truss 12, a first transmission assembly and a first driving device 13 arranged on the truss 12, the first transmission assembly includes two groups of first transmission wheel groups 14 and a first conveyor belt 16 arranged between the first transmission wheel groups 14, the first driving device 13 includes a driving motor arranged on the truss, the output end of the driving motor is connected to a driving wheel, and the first transmission wheel group 14 is provided with a driven wheel. The driving motor drives the driving wheel to rotate, thereby driving the driven wheel to rotate and thereby driving the first transmission wheel group 14 to rotate. The second conveying unit 2 includes a bracket 22 and a second transmission assembly arranged on the bracket 22, the second transmission assembly includes two groups of second transmission wheel groups 222 and a second conveyor belt 221 arranged between the second transmission wheel groups 222, a group of second transmission wheel groups 222 in the second transmission assembly and a group of first transmission wheel groups 14 in the first transmission assembly are arranged on the same transmission shaft 15. At this time, the second transmission assembly relies on the first transmission assembly to provide power, saving manufacturing costs.

[0048] In some embodiments, reference Figure 6 、 Figure 7 and Figure 8 The cross-section of the truss 12 is trapezoidal, wherein the width between the lower chords of the truss 12 is greater than the width between the upper chords; the reinforcements provided at the connection parts at both ends of the truss 12 can also effectively ensure the rigidity of the trusses 12 at the connection position; the side of the truss 12 is a slightly arcuate structure, which can effectively improve the stability of the truss and the rigidity when bearing loads. When the truss is fully loaded with seedlings and seedling trays or in windy weather, the deformation of the truss structure used for erection is small, the maximum shear stress point in the structure (i.e., the weak stress point) is not easily damaged, and the structure is extremely reliable. In addition, the traditional conveying truss structure design is heavy, the construction process is complex, the safety load is low, and the production cost is high. This design uses a new truss structure constructed with standard commercial steel pipes, angle steel, and round steel. It uses steel standard components, which are easy to obtain, simple to process, and lightweight. Every 6 meters is a standard length section, realizing multiple sections that can be freely connected to form a long-span truss-shaped seedling conveyor.

[0049] like Figure 3As shown, a hinged frame is provided at one end of the second conveying unit 2, which is hinged to the first conveying unit 1 through a transmission shaft 15 provided on the first conveying unit 1. When the second conveying unit 2 rotates around its hinged end, the second conveyor belt 221 will always remain taut.

[0050] like Figure 4 As shown, the lifting unit 21 includes a second driving device and a support frame 211 arranged on the first conveying unit 1, the second driving device includes a motor 212, a winding assembly 214 and a pull rope 213, the winding assembly is arranged on the support frame 211 and is rotatably connected with the support frame 211, the motor is used to drive the winding assembly 214 to rotate, and a pulley bracket 22 is provided at the junction of the pull rope 213 and the support frame 211. One end of the pull rope 213 is wound around the winding assembly through the pulley bracket 22, and the other end is connected to the second conveying unit 2 through the pulley bracket 22. When the second conveying unit 2 needs to be lifted, it is only necessary to drive the winding assembly to stretch and wind it up, and the pull rope 213 lifts the second conveying unit 2 around its hinged end through the pulley bracket 22; when the second conveying unit 2 needs to be lowered, the motor drives the winding assembly to lengthen the pull rope 213, and the pull rope 213 lowers the height of the second conveying unit 2 around its hinged end through the pulley bracket 22.

[0051] like Figure 5 As shown, a seedling tray placement section 223 is provided at the discharge end of the second conveyor unit 2. This section is used to store the seedling trays and seedlings conveyed out of the discharge end by the second conveyor unit 2. The section is equipped with a roller assembly comprising multiple roller assemblies arranged longitudinally along the support 22. Each roller assembly comprises multiple rollers, the rotation centers of which are connected by a common central axis. When the seedling trays and seedlings are transferred to the section 223, they can rest there, making it convenient for staff to remove them from the section.

[0052] like Figure 1 and Figure 4 As shown, at least two groups of walking units 4 are provided at the bottom of the first conveying unit 1, and the walking units 4 are respectively arranged on tracks laid on the ridges, so that the overhead crane can move in the field and can better carry out the work of conveying rice seedling trays and seedlings in the field.

[0053] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0054] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not necessarily mean that the components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that the direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0055] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0056] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention falls within the scope of protection of the present invention.
