[0032] Please refer to Figure 1 and 2 , an automatic garlic sprout seed metering machine of the present invention includes:

[0033] A silo 100, including a housing 1001 and an inner bin 1002 provided therein, and the housing 1001 is provided on a base 101;

[0034] A conveying unit 200, including a combined conveyor belt, the position of which is adjusted by a horizontal moving unit 215. A blanking cylinder that can move along with it is provided at the discharge end of the combined conveyor belt for sequentially conveying garlic sprout seeds to the planting area; and,

[0035] A traveling unit 300 is provided below the silo 100, including guide wheels 305 symmetrically distributed in two straight rows and a driving wheel 306 provided between the two rows of guide wheels 305 for driving the silo 100 and the conveying unit 200 to move along a specified path.

[0036] In this embodiment, by moving the machine body along the specified path in the planting area, that is, in order to expand the planting area in the greenhouse, generally only a very narrow cement platform is left in the middle of the greenhouse for zoning. The two rows of guide wheels 305 in this embodiment are clamped on the side of the cement platform, and cooperate with the driving wheel 306 to make the machine body move forward, realizing the stable movement of the machine body. Cooperating with the conveying unit 200 to sequentially convey and place the garlic sprout seeds in the silo 100 into the planting area, so that the garlic sprout seeds are arranged orderly and densely, replacing manual labor, greatly reducing the labor intensity, and improving the work efficiency.

[0037] For a further embodiment, please refer to Figure 4 , the guide wheels 305 are installed on a movable support plate, and the distance between the two rows of guide wheels 305 is controlled by a cylinder, so as to adapt to cement platforms of different widths and improve the application range of the device.

[0038] In one embodiment, please refer to Figure 3, The combined conveyor belt includes a main conveyor belt 201 disposed below the discharge port of the silo 100. At the discharge end of the main conveyor belt 201, there is a first branch conveyor belt 202 disposed along the side wall of the silo 100 and with a width only allowing a single row of garlic sprout seedlings in a positive posture to be arranged, which is used to convey the garlic sprout seedlings in a positive posture. On one side of the first branch conveyor belt 202, there is a second branch conveyor belt 203 for conveying the garlic sprout seedlings in an inverted posture. At the junction of the two branch conveyor belts, there is a rotatable separation baffle 204. On the first branch conveyor belt 202, there is a detection unit 211 for detecting the posture of the garlic sprout seedlings. Specifically, the detection unit 211 adopts a module with image scanning and detection functions. The separation baffle 204 is controlled to rotate by a stepping motor 205. The detection data of the detection unit 211 is transmitted to the controller, and the controller controls whether the stepping motor 205 drives the separation baffle 204 to work;

[0039] Among them, it should be noted that the garlic sprout seedlings in a positive posture refer to the posture with the garlic scape facing upward, and the garlic sprout seedlings in an inverted posture refer to the posture with the garlic scape facing downward.

[0040] In this embodiment, the garlic scapes exported from the silo 100 are sequentially conveyed to the first branch conveyor belt 202 through the main conveyor belt 201 and are conveyed forward in a single row on the first branch conveyor belt 202. After passing through the detection unit 211, it is detected whether the posture of the garlic sprout seedlings is in a positive posture or an inverted posture. When in a positive posture, the garlic sprout seedlings are continuously conveyed to the discharge end on the first branch conveyor belt 202. When in an inverted posture, the garlic sprout seedlings are deflected by the separation baffle 204 to the second branch conveyor belt 203 and conveyed to the discharge end, classifying the garlic sprout seedlings with different postures after blanking, which is convenient for subsequent planting.

[0041] In one embodiment, please refer to Figure 3 、 Figure 5 and Figure 6 , the blanking cylinder includes a first blanking cylinder 206 and a second blanking cylinder 207 corresponding to the first branch conveyor belt 202 and the second branch conveyor belt 203. At the upper opening of the second blanking cylinder 207, there is a guiding inclined plate 212 connected to the second branch conveyor belt 203. On the guiding inclined plate 212, there is a convex plate 213 protruding upward for assisting the garlic sprout seedlings in an inverted posture being conveyed to be flipped to a positive posture. At the discharge end of the first branch conveyor belt 202, there is a clamping mechanism for transferring the garlic sprout seedlings in a positive posture to the first blanking cylinder 206 while maintaining their original posture.

[0042] Among them, the cylinder wall of the second blanking cylinder 207 facing the second branch conveyor belt 203 is provided with a notch, which is convenient for connecting with the guiding inclined plate 212 to guide and convey the garlic sprout seedlings.

[0043] In this embodiment, the garlic sprout seeds that are conveyed to the discharge end on the first branch conveyor belt 202 in a forward posture are clamped at the garlic scape by the clamping mechanism and translated to the mouth of the first blanking cylinder 206, so that the garlic sprout seeds fall into the planting area in a forward posture. The garlic sprout seeds that are conveyed to the discharge end on the second branch conveyor belt 203 in an inverted posture move to the second blanking cylinder 207 through the guiding inclined plate 212. Due to the horizontal conveying force of the second branch conveyor belt 203, the gravity after leaving the discharge end of the second branch conveyor belt 203, and the blocking force of the convex plate 213 and the garlic scape of the inverted garlic sprout seeds, the inverted garlic sprout seeds present a flipping posture during the process of entering the second blanking cylinder 207, and present a forward posture after falling into the second blanking cylinder 207 and fall into the planting area, so that the garlic sprout seeds in the planting area are all arranged in an orderly manner in a forward posture, which is convenient for the subsequent growth of the garlic sprout seeds.

[0044] In one embodiment, please refer to Figure 3 , the clamping mechanism includes a rotating component 209 and two telescopic clamping components 210. The included angle between the two telescopic clamping components 210 is equal to the included angle between the rotating component 209 and the line connecting the first blanking cylinder 206 and the second blanking cylinder 207. Among them, a guiding plate 208 inclined downward towards the first blanking cylinder 206 is provided on the second blanking cylinder 207. The guiding plate 208 communicates the first blanking cylinder 206 and the second blanking cylinder 207. A rotatable baffle 214 for guiding the garlic sprout seeds to transfer from the second blanking cylinder 207 into the first blanking cylinder 206 is provided in the second blanking cylinder 207.

[0045] Among them, the telescopic clamping component 210 includes a telescopic cylinder and a clamping cylinder. It also includes a control box 102.

[0046] In this embodiment, when the garlic sprout seeds on the first branch conveyor belt 202 move to the discharge end, the telescopic clamping component 210 extends and clamps the garlic sprout seeds, and then pulls them back horizontally and puts them into the first blanking cylinder 206; when the quantity gap between the garlic sprout seeds in the forward posture and the inverted posture on the first branch conveyor belt 202 is too large, independent control is carried out as needed. That is, when there are more garlic sprout seeds in the forward posture, the garlic sprout seeds are evenly distributed into the first blanking cylinder 206 and the second blanking cylinder 207 by the two clamping mechanisms. That is, when one clamping mechanism clamps the garlic sprout seeds to the second blanking cylinder 207, the other clamping mechanism can synchronously clamp and convey the garlic sprout seeds on the first branch conveyor belt 202. When there are more garlic sprout seeds in the inverted posture, after the garlic sprout seeds are flipped into the second blanking cylinder 207, the rotatable baffle 214 is controlled to flip upward, so that the garlic sprout seeds in the forward posture in the second blanking cylinder 207 slide into the first blanking cylinder 206 through the guiding plate 208, thereby realizing the balance of the falling quantity of the garlic sprout seeds in the first blanking cylinder 206 and the second blanking cylinder 207.

[0047] In one embodiment, please refer to Figure 4 , the walking unit 300 further includes telescopic cylinders 301 respectively arranged at the front and rear ends of the side wall of the base 101. A telescopic extension arm 302 is arranged in the telescopic cylinder 301. A side wheel 303 is arranged at the front end of the extension arm 302, and a guiding chute is formed on the extension arm 302. The bottom end of the conveying unit 200 is slidably connected with the extension arm 302 through a connecting slider 304 (that is, connecting sliders 304 are arranged at both ends of the bottom of the first branch conveyor belt 202). Among them, the extension arm 302 is driven to extend and contract hydraulically.

[0048] With such a setting in this embodiment, when the machine body moves on the cement platform, by driving the extension arm 302 to extend, the side wheel 303 at its end contacts the ground on the inner side of the greenhouse, so that the machine body maintains stability during the movement. And when the conveying unit 200 adjusts its position through the horizontal moving unit 215, the conveying unit 200 slides on the extension arm 302, and the extension arm 302 can also provide a supporting force for it, thereby maintaining the stability of the conveying unit 200 during operation and enabling the machine body to work stably and efficiently.

[0049] In one embodiment, please refer to Figure 7 , it further includes a material blocking mechanism 216. The material blocking mechanism 216 includes a material blocking rod 2161 arranged on the first branch conveyor belt 202 and capable of intermittently reciprocatingly rotating to adjust the distance between adjacent garlic sprout seeds, and a material blocking plate 2162 arranged at the discharge port of the material bin 100 to adjust the discharging speed of the garlic sprout seeds. With such a setting in this embodiment, it is convenient to adjust the discharging quantity of the material bin 100 and the conveying speed of the garlic sprout seeds on the conveying unit 200, and avoid the problem that too many garlic sprout seeds are piled up and conveyed rapidly to the discharge end, resulting in the difficulty for the telescopic clamping assembly 210 to work efficiently.

[0050] In one embodiment, please refer to Figure 7 , a reset member 2163 is inserted at one end of the material blocking rod 2161. An external gear 2164 is arranged on one side of the reset member 2163. The external gear 2164 is intermittently meshed and connected with a first missing gear disc 2165 on one side. A second missing gear disc 2166 coaxial with the first missing gear disc 2165 is arranged on one side of the first missing gear disc 2165. The second missing gear disc 2166 is intermittently meshed and connected with a moving rack 2167 arranged on the upper side. One end of the moving rack 2167 is connected with the material blocking plate 2162, and the other end is connected with an elastic member 2168. Among them, the length of the tooth missing area of the first missing gear disc 2165 is greater than the length of the tooth missing area of the second missing gear disc 2166. Among them, the first missing gear disc 2165 and the second missing gear disc 2166 are controlled to rotate by a motor; the reset member 2163 is a torsion spring and pin shaft structure.

[0051] In this embodiment, when the first missing gear disc 2165 rotates, it is intermittently meshed and connected with the external gear 2164, so that the material blocking rod 2161 reciprocally lifts and drops under the action of the reset member 2163, intermittently releasing the garlic sprout seedlings on the first branch conveyor belt 202, reducing the subsequent feeding pressure. At the same time, the second missing gear disc 2166 is meshed and connected with the moving rack 2167, and the meshing time is longer than the meshing time between the external gear 2164 and the first missing gear disc 2165, so that the material blocking plate 2162 intermittently blocks the discharge port of the storage bin 100, controlling the continuous falling of the garlic sprout seedlings and preventing the problem of excessive subsequent feeding pressure. It is only necessary that the working frequency of the material blocking rod 2161 is higher than that of the material blocking plate 2162.

[0052] In one embodiment, please refer to Figure 6 and Figure 9 , the inner bin 1002 includes a feeding bin 10021 and a discharging bin 10022. A vibrating sieve plate 10023 for screening garlic sprout seedlings of different sizes is provided between the two bins 100. Among them, the conveying unit 200 is provided on both sides of the bin 100 for respectively conveying the screened garlic sprout seedlings to different planting areas. This embodiment is configured in this way to facilitate screening two types of garlic sprout seedlings in the bin 100 according to size and respectively putting them into different planting areas. Because garlic sprout seedlings of different sizes have different later growth trends, which will affect the subsequent harvesting. By classified feeding, balanced harvesting can be achieved.

[0053] In one embodiment, please refer to Figure 4 , moving wheels 307 are provided at the four corners of the base 101, and the height of the moving wheels 307 can be adjusted. Among them, the moving wheels 307 can be controlled to be retracted and lowered by a cylinder. This embodiment is configured in this way that when the device is not working, the moving wheels 307 facilitate the movement of the machine body. When the device is moving on a cement platform, the moving wheels 307 are retracted upward, which does not affect the normal operation of the device, and it is convenient and fast to use.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
