Description

Technical Field

[0001] The invention relates to the technical field of agricultural seedling racks, and in particular to a cage-shaped seedling rack for unmanned aerial vehicle seedling throwing. Background Art

[0002] With the development of modern agricultural technology, drones are increasingly used in the agricultural field, especially in sowing and seedling throwing. However, there are many shortcomings in the existing drone seedling throwing system. For example, the seedling rack design in patent CN 220830754 U fails to fully consider the stability and load balance of the drone during flight, which increases the difficulty of flight control and may affect the accuracy and efficiency of seedling throwing. In addition, patent CN 119256717 A includes a symmetrical layout of seedling racks, as well as triangular and square seedling racks. Although this method is conducive to weight balance, it is not conducive to seedling emergence. It is necessary to set a separate seedling emergence mechanism for each slide, which increases the cost and weight, and is not conducive to drone-mounted flight. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a cage-shaped seedling rack for drone seedling throwing that has a balanced structure and is convenient for seedling emergence.

[0004] Technical solution: To achieve the above-mentioned purpose, the cage-shaped seedling rack for UAV seedling throwing of the present invention comprises a plurality of chute components capable of accommodating seedlings, wherein the chute components have accommodating grooves, and the accommodating grooves have notches for seedling leaves of the seedlings to pass through;

[0005] All the chute components are arranged in a circular array, and the lower end of each chute component has a seedling outlet located on the front side and a top outlet located on the back side. The central axes of all the top outlets converge at the same center point. When in use, the chute components are arranged vertically.

[0006] Furthermore, the cross-sectional shape of the receiving groove is a trapezoid. When in use, the root of the used rice seedling has a matrix block or a seedling pot filled with a matrix, and the seedling leaves of the rice seedling extend from the notch to the outside of the chute component.

[0007] Furthermore, adjacent chute components are connected by a plurality of dispersedly arranged connecting strips; and the lower end of the cage-shaped seedling rack has a connecting seat for connecting all the chute components.

[0008] In one solution, the connection seat and all the slide slot components are manufactured by an integrated molding method, which is difficult to mold. Therefore, in a preferred solution, the slide slot component can be disassembled relative to the connection seat, and the connecting strip can also be disassembled relative to the connection seat, so that all the slide slot components can be separately molded and then assembled, which greatly reduces the production cost.

[0009] Furthermore, a connecting ear is provided on the inner side of the upper end of the chute component, and the connecting ears of all the chute components are connected to the same annular component, and the annular component is provided with a hanging hole. The annular component can not only reinforce and connect all the chute components, but also the hanging holes on the annular component can be connected to the drone through the connecting mechanism, so that the drone can drive the cage-shaped seedling rack and the seedling separation mechanism to fly.

[0010] Furthermore, in one solution, the chute component can be disassembled relative to the connecting seat, and the connecting strip is a soft material, so that all the chute components can be flattened. In this way, after all the chute components are flattened, seedling cultivation can be carried out directly, that is, the substrate block or seedling pot is first loaded into the chute component, and then the seed is planted for seedling cultivation. A special seedling loading device can also be provided to load the cultivated seedlings into the chute component. Specifically, a first seedling conveying mechanism, a positioning mechanism and a first pushing mechanism can be provided. The flattened chute component is placed on the positioning mechanism. The first seedling conveying mechanism has seedlings arranged in rows, and the first seedling conveying mechanism has a partition that keeps the seedling row spacing consistent with the spacing of the chute components. The first pushing mechanism pushes multiple rows of seedlings into each chute component at the same time. After the seedling loading is completed, the flattened chute component is fixed relative to the connecting seat to restore the circular array arrangement.

[0011] In another scheme, a revolving frame for fixing the cage-shaped seedling rack can be set up, and a second seedling conveying mechanism and a second pushing mechanism can be set up. The second seedling conveying mechanism is a conveyor belt with a partition, and the driving pulley of the conveyor belt is coaxially fixed with the revolving frame. In this way, every time the revolving frame rotates a step angle, an empty slide groove component can be aligned with a conveying groove loaded with seedlings on the second seedling conveying mechanism. The seedlings in the conveying groove can be pushed into the slide groove component by the second pushing mechanism, which can improve the convenience of loading seedlings.

[0012] Beneficial effects: The cage-shaped seedling rack for UAV seedling throwing of the present invention has the following beneficial effects:

[0013] (1) All chute components are arranged in a circular array with high structural regularity. After the chute components are loaded with seedlings, the overall weight of the cage-shaped seedling rack is balanced, which is convenient for UAV loading and reduces the difficulty of flight control.

[0014] (2) The seedling rack with a round cage structure is convenient for the layout of the seedling separation mechanism. The seedling separation mechanism can be placed in the middle of the round cage structure. Since the central axes of all the top outlets converge at one point, each top outlet can be equipped with an ejection rod, and the same seedling separation mechanism controls all the ejection rods to perform ejection operations in sequence to complete the seedling operation, which is conducive to the compactness, lightness and miniaturization of the structure.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 The cage-shaped seedling rack for transplanting rice seedlings by drone shown in the figure comprises a plurality of chute components 1 capable of accommodating rice seedlings, wherein the chute components 1 have an accommodating groove 1a, and the accommodating groove 1a has a notch 1b for the seedling leaves of the rice seedlings to pass through; all the chute components 1 are arranged in a circular array, and the lower end of each of the chute components 1 has a seedling outlet 1c located on the front side and a top outlet 1d located on the back side (such as Figure 3 As shown), the central axes of all the top outlets 1d converge at the same center point. When in use, the chute component 1 is arranged vertically.

[0027] Based on the above structure, all the chute components 1 are arranged in a circular array with high structural regularity. After the chute components 1 are loaded with seedlings, the overall weight of the cage-shaped seedling rack is balanced, which is convenient for drone loading and reduces the difficulty of flight control. The seedling rack with a circular cage structure is convenient for the layout of the seedling separation mechanism 5. The seedling separation mechanism 5 can be placed in the middle of the circular cage structure. Since the central axes of all the top outlets 1d converge at one point, an ejection rod 5a can be respectively configured for each top outlet 1d, and the same seedling separation mechanism controls all the ejection rods a to perform ejection operations in sequence to complete the seedling emergence operation, which is conducive to the compactness, lightweight and miniaturization of the structure.

[0028] Specifically, Figure 5 and Figure 6 As shown, the seedling separation mechanism 5 includes a mechanism base 5b in addition to the ejection rod 5a, and also includes a motor 5c installed in the middle of the mechanism base 5b, and the motor 5c drives the rotating frame 5d to perform translational rotational motion with a specific radius. Specifically, the output shaft of the motor 5c is connected to the rotating frame 5d through a first eccentric shaft 5e, and a plurality of second eccentric shafts 5f are connected between the rotating frame 5d and the mechanism base 5b, and the eccentric distances of the two eccentric shafts are equal, and a connecting rod 5g is connected between the rotating frame 5d and each ejection rod 5a. With this structure, the output shaft of the motor 5c rotates one circle, and all the chute components 1 can discharge a seedling in sequence, completing a round of seedling throwing operation, with a high seedling throwing frequency, and the seedlings in each chute component 1 are balanced and reduced, which can maintain the overall balance of the cage-shaped seedling rack, and the seedling separation operation of all the chute components 1 is driven by the same motor, which is low in cost and low in control difficulty.

[0029] Preferably, the cross-sectional shape of the receiving groove 1a is a trapezoid. Figure 7 As shown, the roots of the rice seedlings used have a substrate block or a seedling pot filled with a substrate, and the leaves of the rice seedlings extend outward from the notch 1b to the outside of the chute component 1.

[0030] Preferably, adjacent chute components 1 are connected by a plurality of dispersedly arranged connecting bars 2; and the lower end of the cage-shaped seedling rack has a connecting seat 3 for connecting all the chute components 1.

[0031] In one embodiment, the connection seat 3 and all the chute components 1 are manufactured by an integrated molding method, which is difficult to mold. Therefore, in a preferred embodiment, the chute component 1 can be disassembled relative to the connection seat 3, and the connecting strip 2 can also be disassembled relative to the connection seat 3, so that all the chute components 1 can be separately molded and then assembled, which greatly reduces the production cost.

[0032] Preferably, if Figure 2As shown, a connecting ear 1e is provided on the inner side of the upper end of the chute component 1, and the connecting ears 1e of all the chute components 1 are connected to the same annular component 4, and a hoisting hole 4a is provided on the annular component 4. Figure 4 The circular ring component 4 can not only reinforce and connect all the chute components 1, but also the hoisting holes 4a on the circular ring component 4 can be connected to the drone through the connecting mechanism, so that the drone can drive the cage-shaped seedling rack and the seedling separation mechanism to fly.

[0033] Preferably, in one embodiment, the chute component 1 can be disassembled relative to the connecting seat 3, and the connecting strip 2 is made of soft material, so that all the chute components 1 can be flattened. In this way, after all the chute components 1 are flattened, seedlings can be directly raised, that is, substrate blocks or seedling pots are first loaded into the chute components 1, and then the seeds are planted for seedling cultivation. A special seedling loading device can also be provided to load the cultivated seedlings into the chute components 1, specifically, as Figure 8 As shown, a first seedling conveying mechanism 8, a positioning mechanism 6 and a first pushing mechanism 7 can be provided, the flattened chute component 1 is placed on the positioning mechanism 6, the first seedling conveying mechanism 8 has seedlings arranged in rows, and the first seedling conveying mechanism 8 has partitions for keeping the seedling row spacing consistent with the spacing of the chute component 1, the first pushing mechanism 7 pushes multiple rows of seedlings into each chute component 1 at the same time, and after the seedlings are loaded, the flattened chute component 1 is fixed relative to the connecting seat 3 to restore the circular array arrangement.

[0034] In another embodiment, the connecting strip 2 is made of a hard material, such as Fig. 9 As shown, a revolving frame 9 for fixing a cage-shaped seedling rack can be provided, and a second seedling conveying mechanism 10 and a second pushing mechanism 11 can be provided. The second seedling conveying mechanism 10 is a conveyor belt with a partition, and the driving pulley of the conveyor belt is coaxially fixed with the revolving frame 9. In this way, every time the revolving frame 9 rotates a step angle, an empty chute component 1 can be aligned with a conveying chute loaded with seedlings on the second seedling conveying mechanism 10, and the seedlings in the conveying chute can be pushed into the chute component 1 by the second pushing mechanism 11, thereby improving the convenience of loading seedlings.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
