TECHNICAL FIELD

[0001] The present application relates to the garlic seeding technical field, and in particular to a garlic straight-bud-seeding secondary orientation device. BACKGROUND

[0002] Garlic is a crop with unique spicy flavor and important economic value, rich in various nutrients and bioactive substances, and has wide application value in food, medicine and other fields, so it is widely planted in the world. In order to improve the yield of garlic, it is necessary to ensure that the garlic seeds are planted in an upright position with the bud tip upward, which is one of the key cultivation measures to ensure normal growth and development and achieve high yield. Compared with corn, wheat and other staple food crops, the garlic seeding operation is more difficult, and the manual seeding efficiency is low and the labor intensity is high. Therefore, the realization of garlic seeding mechanization has become an inevitable trend of modern agricultural development.

[0003] In the process of garlic mechanized seeding, it is a key link to adjust the garlic seeds with the bud tip upward. The traditional mechanical orientation method, such as three-stage directional bucket and spiral guide pipe, has the problems of low orientation success rate and insufficient stability. Current research focuses on machine vision recognition of bud tip and realizes orientation combined with electric control actuator, but this kind of scheme has high cost and still faces many challenges in practical application. Therefore, it is urgent to design a device with reasonable structure that can reliably realize accurate orientation of garlic seed bud tip. SUMMARY

[0004] The purpose of the present application is to solve the above technical problems, and provide a garlic straight-bud-seeding secondary orientation device, which can improve the success rate of garlic seed bud tip upward and realize accurate orientation.

[0005] In order to achieve the above purpose, the present application is realized by the following technical scheme:

[0006] The garlic seed is planted in the bud, and the secondary orientation device comprises a V-shaped channel, an orientation spoon, an orientation box, a vibration motor, a motor support, an eccentric wheel, a roller seat and a roller, characterized in that the orientation box is in a funnel structure of an upper rectangular body and a lower cylindrical body, an opening is arranged at the top of the orientation box for mounting the orientation spoon, and an opening is arranged at the bottom of the orientation box for the garlic seed to fall after the orientation is completed; a circular hole is arranged on one side wall of the orientation box and is fixed on the frame through a bolt assembly, a fan-shaped opening is arranged on the opposite side wall, the size of the fan-shaped opening is slightly larger than the lower end section of the V-shaped channel, an inner connecting plate is arranged on the inner side of the side wall provided with the fan-shaped opening, and an outer connecting plate is arranged on the outer side of the side wall provided with the fan-shaped opening; the orientation spoon is hinged to the inner connecting plate through a spoon torsional spring and a spoon bolt assembly; the V-shaped channel is inclinedly arranged and is hinged to the outer connecting plate through a channel torsional spring and a channel bolt assembly; the upper end of the V-shaped channel is a planting port, the size of the planting port is suitable for accommodating a single garlic seed, and the lower end of the V-shaped channel is an outlet with a fan-shaped section, the size of the outlet is limited to only allow the single garlic seed to pass through and not to be turned over; the outlet passes through the fan-shaped opening and is in contact with the orientation spoon; a connecting plate is arranged at the bottom of the V-shaped channel and is fixed with the roller seat through a bolt and a nut; the roller is mounted on the roller seat; the vibration motor is fixed on the frame through the motor support and is located below the roller; the eccentric wheel is mounted on the output shaft of the vibration motor and is in contact with the roller, so that the V-shaped channel is driven to generate micro-vibration under the driving of the vibration motor and the garlic seed is prevented from being blocked.

[0007] Preferably, the upper end planting port of the V-shaped channel is close to the garlic seed outlet of the seed taking device, so as to ensure that the garlic seed can enter the V-shaped channel.

[0008] Preferably, the inner connecting plate and the outer connecting plate are respectively provided with a spoon torsional spring limiting groove and a channel torsional spring limiting groove, so as to limit the displacement of the corresponding torsional spring.

[0009] Preferably, the connecting plate of the V-shaped channel is located at the joint of the planting port and the lower end fan-shaped channel, the vibration is transmitted to the joint through the eccentric wheel and the roller of the vibration motor, and the garlic seed is prevented from being accumulated and blocked.

[0010] Preferably, the spoon torsional spring is arranged between the orientation spoon and the inner connecting plate, so as to apply a small elastic force to the orientation spoon, make the orientation spoon abut against the outlet of the V-shaped channel, and reset in time after being pushed away by the garlic seed; the channel torsional spring is arranged between the outer connecting plate and the hinged plate of the V-shaped channel, so as to provide a restoring force when the V-shaped channel moves upward due to vibration, make the roller keep in contact with the outer contour of the eccentric wheel and move with the eccentric wheel.

[0011] Preferably, the orientation part of the orientation spoon is a curved mesh structure with a square mesh, the convex surface of the curved mesh structure is used for contacting with the garlic seed, and the posture of the garlic seed with the bud downward is adjusted.

[0012] The application has the following technical effects: the application combines the "V-shaped channel posture pre-screening" with the "curved mesh directional spoon active direction adjusting" secondary direction adjusting mechanism, which significantly improves the success rate of garlic seed bud tip upward. First, the V-shaped channel is obliquely arranged, which effectively limits the degree of freedom of the garlic seeds in the conveying process by virtue of its unique fan-shaped outlet cross section, realizes the preliminary screening and constraint of the posture of the garlic seeds, and lays a stable foundation for subsequent accurate direction adjusting. Second, the curved mesh directional spoon with square mesh is adopted, which can effectively capture and guide the garlic seeds with downward bud tips. In the contact process, the mechanical properties of the curved surface and the mesh make the garlic seeds roll, so as to adjust the bud tip to the upward posture. The two direction adjusting processes cooperate with each other to make up for the shortcomings of single direction adjusting mode, and the overall direction adjusting precision is high and the stability is good. At the same time, the application skillfully uses torsional springs, hinged mechanical structures and the like to realize the elastic reset and automatic return function of the key components. The directional spoon always maintains elastic pressure on the outlet of the V-shaped channel through the spoon torsional spring, so as to ensure that it can quickly reset after each direction adjusting action, and form a constrained posture for the next garlic seed; the V-shaped channel is automatically reset to maintain stable contact with the driving mechanism by cooperating with the channel torsional spring and the vibration driving component while generating anti-blocking micro-vibration. The whole set of device realizes complex functions in a pure mechanical way, without expensive visual recognition system and electric control execution mechanism, and has simple structure, durability, and significantly lower manufacturing and maintenance costs than existing automatic solutions, and is easier to popularize and apply in actual agricultural production. The application integrates the active anti-blocking design, drives the eccentric wheel through the vibration motor, drives the roller fixedly connected with the V-shaped channel, makes the area near the inoculation port of the V-shaped channel produce continuous and controllable micro-vibration. The vibration can effectively break the jamming phenomenon of the garlic seeds caused by irregular shape, ensure the smooth and orderly flow of the garlic seeds in the channel, and fundamentally avoid the interruption of work caused by jamming, and ensure the continuous, efficient and stable working performance of the seeding machine.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-6 As shown, the device of the present invention includes a V-shaped channel 2, a directional spoon 10, a directional box 1, a vibrating motor 3, a motor bracket 4, an eccentric wheel 6, a roller seat 7, and rollers 5. The directional box 1 has a funnel-shaped structure with a cuboid upper section and a cylindrical lower section. Its top has an opening for mounting the directional spoon 10, and its bottom has an opening for the garlic cloves to fall after directional adjustment. One side wall of the directional box 1 has a circular hole 16, which is fixed to the frame by a bolt assembly. The opposite side wall has a fan-shaped opening 15, the size of which is slightly larger than the lower cross-section of the V-shaped channel 2. The directional box 1 has an inner connecting plate 20 on the inner side of the side wall with the fan-shaped opening 15 and an outer connecting plate 21 on the outer side. The directional spoon 10 is hinged to the inner connecting plate 20 by a spoon torsion spring 11 and a spoon bolt assembly 12. The V-shaped channel 2 tilts... The V-shaped channel 2 is inclined and hinged to the outer connecting plate 21 via a channel torsion spring 18 and a channel bolt assembly 14. The upper end of the V-shaped channel 2 is an inoculation port 19, sized to receive a single garlic seed, and the lower end is a fan-shaped outlet, sized to allow only a single garlic seed to pass through without overturning. The outlet passes through the fan-shaped opening 15 and contacts the directional spoon 10. The bottom of the V-shaped channel 2 is provided with a connecting plate 8, which is fixed to the roller seat 7 by bolts and nuts. The roller 5 is installed on the roller seat 7. The vibration motor 3 is fixed to the frame via the motor bracket 4 and is located below the roller 5. The eccentric wheel 6 is installed on the output shaft of the vibration motor 3 and contacts the roller 5. It is used to drive the V-shaped channel 2 to generate micro-vibration under the drive of the vibration motor 3 to prevent the garlic seed from clogging.

[0022] Specifically, the upper end inoculation port 19 of the V-shaped channel 2 is close to the garlic seed outlet of the inoculation device, which ensures that the garlic seeds can enter the V-shaped channel 2.

[0023] Specifically, the inner connecting plate 20 and the outer connecting plate 21 are respectively provided with a spoon torsion spring limiting groove 13 and a channel torsion spring limiting groove 17 for limiting the displacement of the corresponding torsion spring.

[0024] Specifically, the connecting plate 8 of the V-shaped channel 2 is located at the joint of the inoculation port 19 and the lower end fan-shaped channel, and the vibration motor 3 transmits vibration to this position through the eccentric wheel 6 and the roller 5, thereby preventing garlic seeds from being accumulated and blocked.

[0025] Specifically, the spoon torsion spring 11 is arranged between the direction-adjusting spoon 10 and the inner connecting plate 20, which is used to apply a small elastic force to the direction-adjusting spoon 10 so that it is pressed against the outlet of the V-shaped channel 2 and can be reset in time after being pushed away by garlic seeds. The channel torsion spring 18 is arranged between the outer connecting plate 21 and the V-shaped channel hinged plate 22, which is used to provide a restoring force when the V-shaped channel 2 moves upward due to vibration, so that the roller 5 keeps in contact with the outer contour of the eccentric wheel 6 and moves with it.

[0026] Specifically, the direction-adjusting part of the direction-adjusting spoon 10 is a curved mesh structure with square mesh, and the convex surface is used to contact with garlic seeds to adjust the posture of garlic seeds with the bud tip downward.

[0027] In use, the single garlic seed taken out by the seed taking device falls into the V-shaped channel 2 through the V-shaped channel 2, and the connecting plate 8 connects the roller seat 7 and the roller 5 below the opening of the channel. The eccentric wheel 6 is driven to rotate by the vibration motor 3, so that the roller 5 moves up and down in a small amplitude, thereby generating a slight vibration to the V-shaped channel 2, preventing the garlic from being stuck at the inlet. Since the maximum radius of the cross section of the V-shaped channel 2 is smaller than the maximum length of the garlic seed, the garlic seed can only slide in a reclining posture, and the bud tip can only be adjusted to be upward or downward along the channel, and cannot be turned over in the channel, completing the first direction adjustment. When the garlic seed slides out of the outlet of the V-shaped channel 2 and contacts the direction adjusting spoon 10, when the garlic seed slides out: if the bud tip is upward, the bottom of the garlic seed will push away the direction adjusting spoon 10 and directly fall into the lower end cylindrical channel of the direction adjusting box 1 under the action of gravity, keeping the bud tip upward; if the bud tip is downward, the bud tip will insert into the grid of the direction adjusting spoon 10, and by the inertia and gravity of the garlic seed sliding downward, the direction adjusting spoon 10 is pushed away while being self-turned over, so that the bottom of the garlic seed is downward and the bud tip is upward, completing the second direction adjustment. The diameter of the lower end cylindrical channel of the direction adjusting box 1 is smaller than the maximum length of the garlic seed, so that the garlic seed bud tip will not be turned over again in the channel after being sent out upward. Through the two direction adjustment processes, the posture of the garlic seed is first adjusted to two situations of the bud tip being upward or downward, and then combined with the structure characteristics of the direction adjusting spoon and the garlic seed, the ideal sowing posture of the bud tip being upward is finally adjusted, thereby completing the whole direction adjustment process.

[0028] In summary, the present application provides a garlic straight bud sowing and secondary direction adjusting device, which solves the problem of low success rate of the existing mechanical direction adjusting device, adjusts the direction by using the direction adjusting device and the structure characteristics of the garlic seed, ensures that the garlic can be planted in the posture of the bud tip being upward, realizes accurate direction adjustment of the garlic seed, reduces the probability of the bud tip being downward, improves the yield of garlic, and has high application and market value.
