Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a garlic seeder. Background Art

[0002] In agricultural production, the planting of garlic is an important link, and the use of garlic seeders has greatly improved production efficiency. However, due to the agronomic requirement for garlic sowing being to achieve the sowing of garlic with the roots downward and the buds upward and upright, most of the current garlic seeders on the market have some problems and defects in design and use.

[0003] Existing garlic seeders usually directly sow after taking seeds without controlling the scale buds and uprightness, resulting in the inability to guarantee the scale buds and uprightness of garlic during sowing, thus affecting the normal growth and yield of garlic. Achieving the upright sowing of garlic with the roots downward and the buds upward is an important agronomic requirement to ensure the good growth of garlic seeds in the soil. If this requirement cannot be met during sowing, the seeds may be adversely affected during germination and growth.

[0004] In addition, during the garlic sowing process, existing seeders also have problems such as taking too many seeds, missing seeds, and damaging the garlic seeds. Taking too many seeds and missing seeds will result in uneven sowing density, affecting the growth environment of garlic in the field and thus the final yield of garlic. And damage to the garlic seeds during the seed-taking process will directly affect their germination rate and seedling emergence rate, which is not conducive to achieving high yields.

Thus, features defined with "first", "second", and "third" may explicitly or implicitly include one or more of such features.

[0057] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0058] As Figures 1 to 9 shown, in a schematic embodiment of the garlic planter of the present utility model, the garlic planter includes a vehicle body 1, on which a seed box 2, a seed-taking mechanism 3, a primary correction mechanism 4, a sowing mechanism 5, and a driver are installed.

[0059] The seed-taking mechanism 3 includes a seed-taking housing 31, in which two seed-taking sprockets 32 are installed vertically. A seed-taking chain 33 is installed between the two seed-taking sprockets 32. A plurality of seed-taking claws 34 are installed along the seed-taking chain 33, and the seed-taking claws 34 have a plurality of claw teeth 35. An extension slot 36 and a feeding port 37 are formed on the rear side plate of the seed-taking housing 31. A plurality of extension slots 36 are arranged in parallel to enable the claw teeth 35 of the seed-taking claws 34 to extend out of the seed-taking housing 31 through the corresponding extension slots 36. The top end of the extension slot 36 is connected to the feeding port 37. The distance between the rear side of the seed-taking chain 33 and the rear side plate of the seed-taking housing 31 gradually increases from bottom to top. An open mouth 21 is provided on the front side plate of the seed box 2, and the rear side plate of the seed-taking housing 31 is embedded and installed in the open mouth 21. A plurality of through slots 22 are provided on the bottom plate of the seed box 2 to enable the plurality of claw teeth 35 of the seed-taking claws 34 to pass through the corresponding through slots 22 from bottom to top. On the front side of the top end of the seed-taking housing 31, there is a discharge box 38, and a discharge port 39 is formed at the bottom end of the discharge box 38.

[0060] The primary correction mechanism 4 is a correction tube, and the top end of the correction tube is connected to the discharge port 39. The correction tube is a spring tube, which is divided into a first guiding portion 41, a second guiding portion 42, and a third guiding portion 43 from top to bottom. Both the first guiding portion 41 and the third guiding portion 43 are arranged vertically. The inner diameter of the third guiding portion 43 is smaller than that of the first guiding portion 41 to enable the inner diameter of the second guiding portion 42 to gradually decrease from top to bottom. The third guiding portion 43 is shifted forward relative to the first guiding portion 41 to enable the second guiding portion 42 to be inclined.

[0061] The sowing mechanism 5 includes a sowing support 51, a sowing duckbill assembly 52 and a sowing drive assembly 53. The sowing duckbill assembly 52 is located directly below the bottom end of the correction tube and has two sowing half-duckbill components 521 hinged to each other. One sowing half-duckbill component 521 is fixedly mounted on the sowing support 51. The sowing support 51 is slidably mounted on the vehicle body 1 to slide up and down between a first height position and a second height position. When the sowing support 51 is lowered to the second height position, the sowing duckbill assembly 52 is inserted into the soil and opened under the drive of the sowing drive assembly 53.

[0062] The driver is connected to the seed sprocket 32 ​​and the sowing support 51 through a chain transmission mechanism, so as to respectively drive the seed sprocket 32 ​​and the sowing support 51 to rotate and rise and fall when the vehicle body 1 moves forward.

[0063] Driven by the driver, the seeding sprocket 32 ​​rotates, the seeding chain 33 runs accordingly, and the seeding claw 34 moves accordingly. When the seeding claw 34 moves from the front side to the rear side, the movement direction is converted from top to bottom to bottom to top, and it passes through the slot 22 upward to enter the seed box 2. Garlic seeds are stacked in the seed box 2, and the seeding claw 34 that enters the seed box 2 and moves upward holds up the garlic seeds and carries them to move further upward. Since the spacing between the portion of the seeding chain 33 located at the rear side and the rear side plate of the seeding machine housing 31 gradually increases from bottom to top, as the seeding claw 34 rises upward, it will also move forward, so that the portion extending through the extension slot 36 gradually decreases. The extended portion of the seeding claw 34 gradually decreases, and the seeds it carries move forward accordingly, and stick to the rear side plate of the seeding machine housing 31. The number of garlic seeds that can be accommodated by the extended portion of the seeding claw 34 is getting smaller and smaller, and the excess garlic seeds gradually fall back to the seed box 2 under the reverse push of the rear side plate of the seeding machine housing 31. When the seed taking claw 34 moves to the delivery entrance 37, the length of the extended part of the seed taking claw 34 can only accommodate one garlic seed, so that the seed taking claw 34 only carries one garlic seed into the delivery entrance 37, causing the garlic seed to flip forward and enter the discharge box 38, and fall into the primary correction mechanism 4 through the discharge port 39.

[0064] By setting the rear part of the seeding chain 33 to be inclined relative to the rear side plate of the seeding machine housing 31, the extended part of the seeding claw 34 gradually decreases during the rising process, so that the rear side plate of the seeding machine housing 31 pushes the excess garlic seeds against the dust seed box 2, so that one seeding claw 34 only carries one garlic seed into the seeding machine housing 31 and conveys it forward to the primary correction mechanism 4, avoiding the single conveyance of multiple garlic seeds, resulting in excessive planting density, thereby avoiding affecting the final yield of garlic. The discharge box 38 forms a cover on the front side to prevent the garlic seeds from being thrown forward when the seeding claw 34 flips forward, ensuring that they fall into the primary correction mechanism 4.

[0065] Garlic seeds are teardrop-shaped, with one end being thin and pointed with scales and the other end being wide. When garlic seeds are planted upright, the scales face upward.

[0066] After the garlic seeds enter the correction tube from the top, they first enter the first guide portion 41. The first guide portion 41 is slightly larger than the length of the garlic seeds, and the garlic seeds fall freely in the first guide portion 41.

[0067] If the bulbils of the garlic seed in the first guide portion 41 fall downward, when the garlic seed falls to the connection between the first guide portion 41 and the second guide portion 42, the bulbils will extend into the gap formed by the bending of the second guide portion 42 relative to the first guide portion 41, so that the top end of the second guide portion 42 supports the bulbils upward, and the garlic seed is turned over with the bulbils as a fulcrum, so that the wide end of the garlic seed is turned to the lower side, and the garlic seed is adjusted to an upright state, and then falls out of the correction tube in an upright state through the third guide portion 43.

[0068] If the garlic seed falls in the first guide portion 41 in a horizontal state with the bulbils facing backward, the wide end of the garlic seed will first enter the second guide portion 42 to adjust the garlic seed to an upright state, and then fall out of the correction tube in an upright state through the third guide portion 43.

[0069] If the garlic seed in the first guide portion 41 falls in a horizontal state and the bulbils are ahead, the thin tip of the garlic seed will enter the second guide portion 42 first. When the garlic seed further falls to the connection between the second guide portion 42 and the third guide portion 43, the bulbils will extend into the gap formed by the bending of the second guide portion 42 relative to the third guide portion 43, so that the top end of the third guide portion 43 supports the bulbils upward, and the garlic seed is turned over with the bulbils as a fulcrum, so that the wide end of the garlic seed is turned to the lower side, and the garlic seed is adjusted to an upright state, and then falls out of the correction tube in an upright state through the third guide portion 43.

[0070] If the bulb of the garlic seed in the first guide portion 41 falls upward, since the gap formed at the bend of the second guide portion 42 relative to the first guide portion 41 and the third guide portion 43 is not sufficient to accommodate the wide end of the garlic seed, the garlic seed slides from top to bottom along the inner wall of the correction tube in an upright state, and finally falls out of the correction tube in an upright state.

[0071] The first-level correction mechanism 4 uses a spring-shaped correction tube, and the gaps generated by the correction tube cooperate with the bulbils to adjust the posture of the garlic seeds. It has a simple structure and is easy to process, so that the garlic seeds can be sown upright, ensuring the normal growth and yield of garlic.

[0072] The top of the dibbling duckbill component 52 is open, and the dropping correction tube falls downward into the dibbling duckbill component 52 of the seeding mechanism 5. The dibbling duckbill component 52 is a conical structure that is wider at the top and narrower at the bottom, and the seeds falling into it can maintain an upright state. Driven by the driver, the seeding bracket 51 descends, and the dibbling duckbill component 52 pierces downward into the soil. The seeding drive component 53 drives the dibbling duckbill component 52 to open, creating a hole in the soil. The driver drives the seeding bracket 51 to rise, and the open dibbling duckbill component 52 leaves the soil. The garlic seeds pass through the space between the two dibbling semi-duckbill members 521 after opening and remain in the hole in an upright state, filling the hole, thereby planting the garlic seeds upright in the soil.

[0073] In the above-mentioned exemplary embodiment, the seed-taking claw 34 of the seed-taking mechanism 3 of the garlic seeding machine can extend out of the seed-taking machine housing 31 through the extension slot 36 and extend into the seed box 2, lifting and taking out the garlic seeds stored in the seed box 2 from bottom to top. As the seed-taking claw 34 rises, the part extending out of the seed-taking machine housing 31 gradually decreases, so that the excess garlic seeds fall off, and only one garlic seed enters the feeding port 37 and is sent into the first-level correction mechanism 4 through the discharge box 38, avoiding over-taking and missing-taking of seeds, ensuring uniform seeding density, and avoiding affecting the final yield of garlic; the correction tube of the first-level correction mechanism 4 is a spring tube, bent in the middle section, so as to form a groove into which the scale bud can be inserted at the bending part, turning the garlic seed so that the scale bud faces upward, and making the garlic stand upright and fall into the seeding mechanism 5 and be planted in the soil, ensuring the normal growth and yield of garlic, and solving the problems of the current garlic seeding machine not controlling the scale bud and uprightness, as well as over-taking and missing-taking.

[0074] How the driver drives the seed-taking sprocket 32 and the seeding bracket 51 through the chain drive mechanism is prior art and not the inventive point of this application.

[0075] In some embodiments, the bottom plate of the seed box 2 is inclined, making the bottom plate of the seed box 2 lower in the front and higher in the rear. The garlic seeds in the seed box 2 can move forward to the bottom of the front side of the seed box 2. After the tooth 35 of the seed-taking claw 34 passes through the through slot 22 and enters the seed box 2, it can ensure that the garlic seeds can be extracted and lifted, ensuring the working efficiency of the garlic seed conveying.

[0076] In some embodiments, the end of the tooth 35 is inclined in the moving direction of the seed-taking chain 33, so that the end of the tooth 35 can block the garlic seeds to a certain extent, preventing them from falling back into the seed box 2 without being pushed back by the rear side plate of the seed-taking machine housing 31.

[0077] In some embodiments, a support plate 30 is installed parallel to the top of the seed taking housing 31, and the extension slot 36 extends to the support plate 30, and the front end of the support plate 30 extends to the discharge box 38. When the seed taking claw 34 moves slowly, the seeds entering the seed taking housing 31 will fall on the support plate 30 and slide forward under the push of the claw teeth 35. When the claw teeth 35 are turned to the vertical position, the garlic seeds fall downward instead of being thrown into the discharge box 38, so that the garlic can be planted at high speed or slow speed.

[0078] In some embodiments, the sowing drive assembly 53 includes a release rope 531 and a trigger rod 532 . The release rope 531 is installed between the two sowing half-duckbill components 521 , and the trigger rod 532 is fixedly installed on the vehicle body 1 .

[0079] When the sowing support 51 is at the first height position, the release rope 531 is located above the trigger rod 532, and the two sowing half-duckbill components 521 are closed. When the sowing support 51 is lowered to the second height position, the sowing duckbill assembly 52 is inserted into the soil, and the release rope 531 contacts the trigger rod 532 and is pulled upward by it, so that the release rope 531 pulls a sowing half-duckbill component 521 that is not connected to the sowing support 51, causing it to swing, thereby opening the sowing duckbill assembly 52, that is, the two sowing half-duckbill components 521 are opened, the soil is propped up to form a hole, and the garlic seeds fall into the hole through the space between the two. The release rope 531 and the trigger rod 532 cooperate to realize the opening of the sowing duckbill assembly 52, which has a simple and compact structure and does not occupy the installation space of the vehicle body 1.

[0080] In some embodiments, a return spring 6 is installed between the two sowing half duckbill components 521. When the two sowing half duckbill components 521 are opened, the return spring 6 is stretched to generate elastic force; when the trigger rod 532 releases the release rope 531, the elastic force generated by the return spring 6 pulls the two sowing half duckbill components 521 to close, so that the insertion duckbill assembly 52 is reset to a closed state, so that the next seed falls and is planted in the soil.

[0081] In some embodiments, the sowing mechanism 5 further includes a lifting drive assembly 54 , and the lifting drive assembly 54 includes a sowing transmission sprocket 541 , a sowing slider 542 and a transmission swing arm 543 .

[0082] The sowing transmission sprocket 541 is mounted on the vehicle body 1 and connected to the chain transmission mechanism. The sowing slider 542 is slidably mounted in the sowing chute 544 horizontally arranged on the sowing support 51, and a transmission swing arm 543 is fixedly mounted on the wheel axle of the sowing transmission sprocket 541, and the transmission swing arm 543 is hinged to the sowing slider 542.

[0083] The driver drives the sowing transmission sprocket 541 to rotate through a chain transmission mechanism. The transmission swing arm 543 rotates accordingly and drives the sowing slider 542 to rotate. During the rotation of the sowing slider 542, it moves up and down and slides back and forth in the sowing chute 544, thereby driving the sowing bracket 51 to lift. The sowing drive assembly 53 enables the driver to use only power devices such as motors and hydraulic motors to provide driving force for the rotation of the shaft. In addition to driving the lifting of the sowing bracket 51 through the chain transmission mechanism and the sowing drive assembly 53, it also facilitates driving the rotation of the seed-taking sprocket 32.

[0084] In some embodiments, it further includes a secondary correction mechanism 7 installed on the vehicle body 1. The secondary correction mechanism 7 includes a correction housing 71, a correction duckbill assembly 72, and a correction drive assembly 73.

[0085] The correction duckbill assembly 72 is located below the correction housing 71 and has two correction semi-duckbill members 721, which are respectively hinged on both sides of the correction housing 71. The correction housing 71 is located directly below the bottom end of the correction tube and directly above the insertion and sowing duckbill assembly 52. Both the upper and lower ends of the correction housing 71 are open, allowing the garlic seeds dropped from the correction tube to enter and fall into the correction duckbill assembly 72. The correction drive assembly 73 is connected to the correction duckbill assembly 72 to drive it to open.

[0086] The secondary correction mechanism 7 is between the primary correction mechanism 4 and the sowing mechanism 5. After the garlic seeds fall out of the correction tube, they first fall into the correction housing 71 and then further fall into the correction duckbill assembly 72. The correction duckbill assembly 72 is a cone with a wider upper part and a narrower lower part. By setting the angle of its inner wall relative to the horizontal plane, the garlic seeds dropped into it are kept upright under the support of its inner wall and are less inclined to the vertical plane when falling out of the correction tube, thereby improving the uprightness of the upright posture of the garlic seeds. The correction drive assembly 73 drives the correction duckbill assembly 72 to open, allowing the garlic seeds to fall downward through the space between the two opened correction semi-duckbill members 721 into the sowing mechanism 5.

[0087] When there is enough installation space on the vehicle body 1, multiple secondary correction mechanisms 7 can be arranged from top to bottom. The inclination of the inner wall of the correction duckbill assembly 72 relative to the horizontal plane can be set to gradually increase from top to bottom, gradually straightening the garlic seeds to the most upright state.

[0088] In some embodiments, the correction drive assembly 73 includes a correction transmission rod 731 and a correction cam 732.

[0089] There are two correction drive rods 731, which are respectively installed on two correction semi-duckbill components 721. There are two correction cams 732, both of which are connected to the chain drive mechanism. Both of the two correction cams 732 have convex portions. The two convex portions both rotate to the horizontal direction, and the orientations of the two convex portions are opposite, and they respectively push against the two correction drive rods 731 to open the correction duckbill assembly 72.

[0090] The driver drives the two correction cams 732 to rotate through the chain drive mechanism. When the two of the two correction cams 732 both rotate to the horizontal plane, they respectively push against the two correction drive rods 731 forward and backward, increasing the distance between the two correction drive rods 731. The two correction semi-duckbill components 721 then open, allowing the garlic seeds to fall out.

[0091] By realizing the opening drive in the way of cam and drive rod, when the driver only uses existing power devices such as motors and hydraulic motors to provide driving force for the shaft rotation, it can not only provide driving force for it, but also provide driving force for other components.

[0092] In some embodiments, a soil covering device 8 is installed at the rear side of the vehicle body 1. The soil covering device 8 is located directly behind the inserting duckbill assembly 52. Thus, after the garlic seeds remain in the pit holes, the excavated soil is filled into the pit holes to bury the garlic seeds in the soil, completing the planting and improving the automation of the planting operation.

[0093] To facilitate planting garlic seeds into the soil, a furrow opener can be installed at the front end of the vehicle body 1. When the sowing support 51 descends, the inserting duckbill assembly 52 can directly fall into the opened planting furrow, without having to overcome the soil resistance to penetrate into it, reducing the wear caused by the soil to the inserting duckbill assembly 52 and extending the service life.

[0094] The driver can be a ground wheel 11 provided on the vehicle body 1, and a sprocket installed on the axle of the ground wheel 11 is connected to the chain drive mechanism 12. When the vehicle body 1 travels on the land, the ground wheel rotates, thereby driving the chain drive mechanism to drive other components to operate, without setting up power devices such as motors and engines that require electrical energy and fuel, etc., which not only simplifies the drive structure but also reduces the use cost of the garlic planter.

[0095] Multiple seed-taking mechanisms 3 can be arranged side by side, and multiple inserting duckbill assemblies 52 of the primary correction mechanism 4 and the sowing mechanism 5 are accordingly arranged, so as to plant garlic in multiple rows of planting furrows simultaneously, improving the operation efficiency.

[0096] When a secondary correction mechanism 7 is installed on the vehicle body 1, a plurality of secondary correction mechanisms 7 are arranged side by side. At this time, only one correction drive assembly 73 may be provided, and the correction drive rods 731 are all arranged horizontally to connect the correction semi-duckbill members 721 of each secondary correction mechanism 7. When the correction cam 732 pushes the corresponding correction drive rod 731 forward or backward, the correction drive rod 731 can drive the correction semi-duckbill members 721 of all the secondary correction mechanisms 7 to swing synchronously, so that the correction duckbill assemblies 72 of the secondary correction mechanisms 7 are opened synchronously.

[0097] In order to reset and close the opened correction duckbill assembly 72, a return spring 6 may also be installed between the two correction semi-duckbill members 721, and the way to achieve the reset is the same as that of the insertion duckbill assembly 52.

[0098] Finally, it should be noted that the embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0099] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered by the scope of the technical solutions claimed by the present invention.
