Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an intelligent garlic seed posture adjustment device. Background Technology

[0002] Garlic is an important economic crop in my country, with its planting area and yield ranking among the world's top. Ensuring that garlic cloves are planted with their bulbils facing upwards is a key technical step in improving garlic yield and quality. Related research shows that garlic bulbs planted with bulbils facing downwards have significantly lower quality than those planted with bulbils facing upwards, thus demonstrating the significant impact of garlic clove orientation on growth quality.

[0003] Existing garlic seed orientation technologies mainly fall into three categories. First, they utilize the physical property that the garlic seed's center of gravity is biased towards one end of the bulb, using inclined planes, grooves, or buoyancy for passive orientation. This method is structurally simple, but its accuracy is greatly affected by differences in garlic seed variety, size, and shape, making consistency difficult to guarantee. Second, they employ a mechanical gripper to grasp the garlic seed and flip it to the target orientation. This method is reliable, but the gripping mechanism has many parts, occupies a large space, and is difficult to integrate into a compact planter. Third, they employ multi-stage mechanical orientation mechanisms, such as a flipping lever combined with a limiting stop to achieve secondary orientation. This method has a complex structure, and its accuracy is prone to decline due to wear after long-term use.

[0004] In summary, existing garlic seed posture adjustment devices struggle to balance structural compactness, calibration accuracy, and adaptability to different operating conditions. Therefore, there is an urgent need for a garlic seed posture adjustment device that is compact, highly adaptable, and has high calibration accuracy. Summary of the Invention

[0005] In view of the problems of complex structure, unstable calibration accuracy and poor adaptability of existing garlic seed posture adjustment devices, the present invention provides an intelligent garlic seed posture adjustment device with compact structure, accurate calibration and strong adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent garlic seed posture adjustment device includes a feeding module, a posture adjustment module, a vision recognition module, and a drive module.

[0008] The feeding module is used to receive garlic seeds and guide them into the device.

[0009] The attitude adjustment module is located below the feeding module and has a cavity for receiving and accommodating garlic seeds.

[0010] A visual recognition module is used to acquire images of the posture of the garlic cloves inside the cavity.

[0011] The drive module is connected to the attitude adjustment module via a transmission.

[0012] The visual recognition module determines the orientation of the garlic cloves based on the acquired posture image and controls the drive module to rotate the posture adjustment module, correcting the garlic cloves to an upright posture with the cloves facing upwards.

[0013] Furthermore, the feeding module includes a housing with a feeding port at the top, a guiding structure inside, and a discharge hole at the bottom. The housing is composed of a separable first shell part and a second shell part, which, when separated, exposes the cavity of the attitude adjustment module, facilitating the removal of stuck garlic seeds.

[0014] Furthermore, the posture adjustment module has a through-tube cavity with an anti-jamming structure on the inner wall to guide the garlic seed into a flat position for image acquisition and posture correction.

[0015] Furthermore, the visual recognition module includes an image acquisition device and a controller. The optical axis of the image acquisition device is aligned with the cavity. The controller is electrically connected to the image acquisition device and the drive module respectively. It is used to determine the orientation of the scales and control the rotation correction based on the posture image. It is also configured to determine whether the garlic seed is stuck and issue an alarm signal when it is determined to be stuck.

[0016] Furthermore, the visual recognition module also includes a supplementary light source, which is positioned between the image acquisition device and the cavity to ensure image acquisition quality.

[0017] Furthermore, the drive module includes a servo motor, the output of which is directly or indirectly connected to the attitude adjustment module.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention detects the posture of garlic cloves and controls their rotation correction through a visual recognition module, which is highly adaptable to differences in garlic varieties and sizes and has a high correction accuracy.

[0020] 2. The feeding module adopts a detachable shell design. When garlic seeds get stuck, the shell can be separated for quick cleaning, which significantly improves the continuity of operation.

[0021] 3. The device integrates feeding, identification, adjustment and seed metering functions into one compact structure, making it easy to integrate into the limited space of a seeder. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the scope of protection of the present invention.

[0028] refer to Figure 1 As shown, an intelligent garlic seed posture adjustment device includes a housing 1, a posture adjustment module 2, a visual recognition module 3, and a drive module 4.

[0029] refer to Figure 2 and Figure 3 The housing 1 is the main structure of the feeding module and adopts a split design, consisting of a first housing part 11 and a second housing part 12. The first housing part 11 is located on the left side and is used to install the drive module 4; the second housing part 12 is located on the right side and is used to rotatably support the attitude adjustment module 2.

[0030] The top of the housing 1 has a feed inlet 13, and its inner wall has a guide structure 14. In this embodiment, the feed inlet 13 is inverted conical, and the guide structure 14 is a set of guide ribs set on the inner wall of the feed inlet, used to guide the falling garlic seeds into the posture adjustment module 2 below in a more regular posture. The side of the housing has a slot 15 for installing the visual recognition module 3, and the bottom of the housing 1 has a garlic seed discharge hole 16.

[0031] refer to Figure 2 The drive module 4 is fixed to the first housing 11. In this embodiment, the drive module 4 is a servo motor, and its output shaft is connected to the transmission connection part 22 of the attitude adjustment module 2 through a transmission assembly, so as to drive the attitude adjustment module to rotate around its axis.

[0032] refer to Figure 3 The posture adjustment module 2 includes a tubular cavity. The left end of the tubular cavity is provided with a transmission connection part 22, which is connected to the drive module 4; the right end is provided with a connecting shaft 21, which is installed in the second housing part 12 through a bearing. The inner wall of the tubular cavity is provided with an anti-jamming structure 23, which is used to move the garlic seed to make it lie flat and prevent it from getting stuck.

[0033] refer to Figure 4The visual recognition module 3 is fixedly installed on the side of the second shell 12, and its lens center axis coincides with the center axis of the posture adjustment module 2, which can clearly capture images of garlic seeds inside the cavity.

[0034] The working process of this embodiment is as follows:

[0035] Garlic seeds fall into the feed inlet 13 via the upstream seed supply mechanism. Under the action of the guiding structure 14, they slide into the cavity of the attitude adjustment module 2 in a relatively regular posture, and tend to lie flat under the action of the anti-jamming structure 23. The visual recognition module 3 captures images of the garlic seeds inside the cavity in real time and transmits them to the controller.

[0036] The controller analyzes the image: if it detects that the garlic seed scales are not facing upwards, it calculates the required rotation angle and sends a command to the drive module 4, which drives the posture adjustment module 2 to rotate by the corresponding angle, correcting the garlic seed posture so that the scales are facing upwards. After correction, the garlic seed enters the next process through the discharge hole 16 under the action of gravity.

[0037] If the controller determines from the image that the garlic seed is stuck, it will issue a stuck alarm signal. At this time, the first shell 11 and the second shell 12 will be separated to open the internal chamber and expel the stuck garlic seed. After clearing, the two shell parts will be reset, and the device will resume normal operation. When maintenance or replacement of parts of the internal modules is required, it can also be done by separating the shells, which is convenient and efficient.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent substitutions, or improvements made to the above embodiments within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
