Description

Technical fields:

[0001] This utility model relates to the technical field of garlic planting equipment, specifically to a garlic planting device with smaller plant spacing. Background technology:

[0002] Currently, garlic planting technology is relatively mature, and planting is mainly completed using agricultural mechanized equipment. For example, our company previously disclosed a garlic planter (authorization announcement number: CN 107124923 B). This technical solution has functions such as rotary tillage, seed collection, planting, and compaction, and the mechanization and integration have been significantly improved. Its disclosed planting mechanism, which is mainly based on a duckbill structure, enables the garlic seed to be planted upright, and the germination rate is high.

[0003] While the aforementioned planting mechanism can significantly improve the positive budding rate, its structure and working principle limit the minimum plant spacing of existing garlic planters to 9cm. However, in actual planting, sometimes a plant spacing of less than 9cm is required; for example, garlic seedlings typically require a plant spacing of 5-6cm. Clearly, existing garlic planters cannot meet these spacing requirements. Current technologies generally employ a staggered planting method with two passes to address this issue, but this undoubtedly severely impacts planting efficiency, and the accuracy of plant spacing is difficult to control during actual operation, easily leading to deviations. Therefore, it is essential to design a new type of garlic planting equipment that can achieve precise and efficient planting with smaller plant spacing.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility model content:

[0005] The purpose of this utility model is to solve the problems existing in the prior art and provide a garlic planting device with smaller plant spacing. It has the advantages of reasonable structural design, compact structural layout, small plant spacing that can be achieved in one planting, uniform and accurate plant spacing, and high planting efficiency.

[0006] This utility model achieves the above objectives by adopting the following technical solutions:

[0007] A garlic planting device with smaller plant spacing includes a frame. The frame is sequentially arranged from front to back with a rotary tillage mechanism, an upright planting mechanism A, an upright planting mechanism B, and a pressing mechanism. The upright planting mechanism A has a seed-collecting mechanism A at its upper end, and the upright planting mechanism B has a seed-collecting mechanism B at its upper end. The seed-collecting mechanisms A and B share a seed box. The upright planting mechanisms A and B have identical structures and are arranged opposite each other. The pressing mechanism is connected to the upright planting mechanism B via chain drive A, and the upright planting mechanism B is connected to the seed-collecting mechanism B via chain drive B. The upright planting mechanism B is connected to the upright planting mechanism A via a synchronous multi-stage gear transmission mechanism, and the seed-collecting mechanism B is connected to the seed-collecting mechanism A via a synchronous reverse transmission mechanism. The planting position of the upright planting mechanism B is located between two adjacent planting positions left by the upright planting mechanism A.

[0008] The upright planting mechanism A includes a planting main shaft. Both ends of the planting main shaft are rotatably mounted on a frame via bearings. A mounting sleeve is fixedly mounted on the planting main shaft. Mounting discs are located at both ends of the mounting sleeve. Multiple mounting tubes are spaced apart along the circumferential direction between the mounting discs. Each mounting tube is rotatably mounted on the mounting disc via bearings. Multiple duckbill assemblies are spaced apart on each mounting tube. Each duckbill assembly includes two planting duckbills spaced apart. An opening and closing linkage is provided between the two planting duckbills. A collision roller is located in the middle of the opening and closing linkage. A corresponding collision roller is located on the mounting sleeve. An opening and closing drive disc is provided at the collision roller position. An upright bracket is provided on the frame on one side of the lowering spindle. An upright mounting plate is provided on the upright bracket relative to the lowering spindle. Multiple upright rollers are spaced apart along the circumferential direction on the upright mounting plate. An upright pull plate is provided on the upright roller. An upright rotating shaft is spaced apart along the circumferential direction on the upright pulling plate, with the number of shafts equal to the number of mounting tubes. The upright rotating shaft is rotatably mounted on the upright pulling plate through a bearing seat. An upright pull rod is rotatably mounted on the upright rotating shaft. The other end of the upright pull rod is fixedly mounted on the end of the corresponding mounting tube.

[0009] The seed-collecting mechanism A includes a seed-collecting bracket mounted on the upper end of the frame. Multiple seed-collecting chains are spaced apart on the seed-collecting bracket, with a dividing plate between adjacent chains. The number of seed-collecting chains is the same as the number of beaks on the mounting tube and they are vertically aligned. The seed-collecting chains are supported by multiple seed-collecting sprockets spaced apart on the seed-collecting bracket. Multiple seed-collecting scoops are evenly spaced on the seed-collecting chains. A seed guide box is inclined below the seed-collecting chains, with a receiving beak at the end of the box. The receiving beak is fixedly mounted on the seed-collecting bracket. All the lowest seed-collecting sprockets are connected via a seed-collecting main shaft.

[0010] The pressing mechanism includes a pressing spindle, both ends of which are rotatably mounted on the frame via bearing seats, and pressing wheels are provided on the pressing spindle.

[0011] The chain drive A includes a drive sprocket A, which is located at the left end of the pressing main shaft. The left end of the planting main shaft in the upright planting mechanism B is provided with a driven sprocket A. The drive sprocket A is connected to the driven sprocket A through a chain A.

[0012] The chain drive B includes a drive sprocket B, which is located at the left end of the planting main shaft in the upright planting mechanism B. The seed taking mechanism B has a driven sprocket B at the left end of the seed taking main shaft. The drive sprocket B is connected to the driven sprocket B via a chain B.

[0013] The synchronous multi-stage gear transmission mechanism includes a driving gear, a driven gear, and multiple intermediate gears. The driving gear is located at the left end of the main shaft of the vertical loading mechanism B, and the driven gear is located at the left end of the main shaft of the vertical loading mechanism A. The driving gear meshes with the driven gear through multiple intermediate gears, and the intermediate gears are mounted on the frame through an intermediate rotating shaft and a bearing with a seat.

[0014] The synchronous reverse transmission mechanism includes two bevel gears A respectively disposed at the right end of the seed-taking main shaft, each bevel gear A being connected to a bevel gear B, the two bevel gears B being connected by a transmission rod, and the bevel gears A and B being disposed on a bevel gear seat.

[0015] The rotary tillage mechanism includes a rotary tillage main shaft, both ends of which are rotatably mounted on the frame via bearing seats. Multiple cutter head seats are spaced apart along the length of the rotary tillage main shaft, and multiple rotary tillage blades are spaced apart along the circumferential direction on the cutter head seats. The rotary tillage main shaft is connected to the agricultural machinery through a transmission box and a gearbox.

[0016] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0017] (1) The unique double-planting layout structure is adopted. By adjusting the spacing between the two planting mechanisms, the planting position of the rear planting mechanism can be located in the middle of the two adjacent planting positions of the front planting mechanism, thereby achieving a smaller plant spacing. (2) By designing chain drive A and chain drive B, the press wheel is used as the power source to transmit power to the rear planting mechanism and the rear seed taking mechanism. In order to ensure the synchronization of the two planting mechanisms, the rear planting mechanism transmits power to the front planting mechanism through a synchronous multi-stage gear mechanism, and the rear seed taking mechanism transmits power to the front seed taking mechanism through a synchronous reverse transmission mechanism. Not only is the power transmission reliable, but the synchronization is also ensured. (3) By setting the two seed taking mechanisms relative to each other, they can share a seed box, which helps to efficiently feed the material. The synchronous reverse transmission mechanism achieves synchronization and reverse rotation at the same time, which meets the requirements of seed taking and feeding. Attached image description:

Detailed implementation method:

[0030] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0033] Furthermore, terms such as “upper end”, “lower end”, “A”, and “B” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figure 1-11 As shown, a garlic planting device with smaller plant spacing includes a frame 1. The frame 1 is equipped with a rotary tillage mechanism 2, an upright planting mechanism A3, an upright planting mechanism B4, and a pressing mechanism 5, arranged sequentially from front to back. The upright planting mechanism A3 has a seed-collecting mechanism A6 at its upper end, and the upright planting mechanism B4 has a seed-collecting mechanism B7 at its upper end. The seed-collecting mechanisms A6 and B7 share a seed box 8. The upright planting mechanisms A3 and B4 have identical structures. The seed-collecting mechanisms A6 and B7... The seven structures are identical and arranged opposite each other. The pressing mechanism 5 is connected to the upright planting mechanism B4 via chain drive A9. The upright planting mechanism B4 is connected to the seed-taking mechanism B7 via chain drive B10. The upright planting mechanism B4 is connected to the upright planting mechanism A3 via synchronous multi-stage gear transmission mechanism 11. The seed-taking mechanism B7 is connected to the seed-taking mechanism A6 via synchronous reverse transmission mechanism 12. The planting position of the upright planting mechanism B4 is located in the middle of the two adjacent planting positions left by the upright planting mechanism A3. This innovative double-planting layout structure allows for adjusting the spacing between the upright planting mechanisms A3 and B4, ensuring that the planting position of the upright planting mechanism B4 is located in the middle of the two adjacent planting positions left by the upright planting mechanism A3, thus achieving a smaller plant spacing. By designing chain drives A9 and B10, the press wheel 502 is used as the power source to transmit power to the upright planting mechanism B4 and the seed-taking mechanism B7. To ensure the synchronization of the two planting mechanisms, the upright planting mechanism B4 transmits power to the upright planting mechanism A3 through a synchronous multi-stage gear mechanism 11, and the seed-taking mechanism B transmits power to the seed-taking mechanism A6 through a synchronous reverse transmission mechanism 12. This not only achieves reliable power transmission but also ensures synchronization. By setting the seed-taking mechanism A6 and the seed-taking mechanism B7 opposite to each other, they can share a seed box 8, which helps to efficiently feed the seed. The synchronous reverse transmission mechanism 12 achieves both synchronization and reverse rotation, meeting the seed-taking requirements.

[0036] The upright planting mechanism A3 includes a planting main shaft 301. Both ends of the planting main shaft 301 are rotatably mounted on the frame 1 via bearing seats. A mounting sleeve 302 is fixedly mounted on the planting main shaft 301. Mounting discs 303 are located at both ends of the mounting sleeve 302. Multiple mounting tubes 304 are spaced apart along the circumferential direction between the mounting discs 303. The mounting tubes 304 are rotatably mounted on the mounting discs 303 via bearing seats. Multiple duckbill assemblies 305 are spaced apart on the mounting tubes 304. Each duckbill assembly 305 includes two planting duckbills 306 spaced apart (the structure and opening / closing principle of the planting duckbill 306 are prior art). An opening / closing connecting rod 307 is provided between the two planting duckbills 306. A collision roller 308 is located in the middle of the opening / closing connecting rod 307. The mounting sleeve 302 is provided with an opening and closing drive disk 309 corresponding to the position of the collision roller 308; an upright bracket 310 is provided on the frame 1 on one side of the lowering spindle 301, and an upright mounting disk 311 is provided eccentrically on the upright bracket 310 relative to the lowering spindle 301. A plurality of upright rollers 312 are provided at intervals along the circumferential direction on the upright mounting disk 311, and an upright pull plate 313 is provided on the upright rollers 312. An upright rotating shaft 314 is provided at intervals along the circumferential direction, equal to the number of mounting tubes 304. The upright rotating shaft 314 is rotatably mounted on the upright pull plate 313 through a seated bearing. An upright pull rod 315 is rotatably mounted on the upright rotating shaft 314, and the other end of the upright pull rod 315 is fixedly mounted on the end of the corresponding mounting tube 304. The principle of parallelograms is used here. The installation tube 304 is driven to rotate by the action of the upright tie rod 315, thereby ensuring that the lowered duckbill 306 is always in an upright state.

[0037] The seed-collecting mechanism A6 includes a seed-collecting bracket 601 mounted on the upper end of the frame 1. Multiple seed-collecting chains 602 are spaced apart on the seed-collecting bracket 601, with a dividing plate 603 between adjacent seed-collecting chains 602. The number of seed-collecting chains 602 is the same as the number of beaks 306 on the mounting tube 304 and they are vertically aligned. The seed-collecting chains 602 are supported by multiple seed-collecting sprockets 604 spaced apart on the seed-collecting bracket 601. Multiple seed-collecting spoons 605 (also called seed collectors, existing technology) are evenly spaced on the seed-collecting chains 602. A seed guide box 606 is inclined below the seed-collecting chains 602, and a receiving beak 607 (existing technology, the lowering beak 306 can open it) is located at the end of the guiding box 606. The receiving beak 607 is fixedly mounted on the seed-collecting bracket 601. All the seed-collecting sprockets 604 at the bottom are connected by a seed-collecting main shaft 608. This achieves stable and reliable seed collection.

[0038] The compaction mechanism 5 includes a compaction main shaft 501, both ends of which are rotatably mounted on the frame 1 via bearing seats. Compaction wheels 502 are mounted on the compaction main shaft 501. This mechanism compacts the tillage layer and provides power for planting.

[0039] The chain drive A9 includes a drive sprocket A901, which is located at the left end of the pressing main shaft 501. The left end of the lowering main shaft 301 in the upright lowering mechanism B4 has a driven sprocket A902. The drive sprocket A901 is connected to the driven sprocket A902 via a chain A903. This drives the upright lowering mechanism B4 to operate.

[0040] The chain drive B10 includes a drive sprocket B1001, which is located at the left end of the planting main shaft 301 in the upright planting mechanism B4. A driven sprocket B1002 is located at the left end of the seed-collecting main shaft 608 in the seed-collecting mechanism B7. The drive sprocket B1001 is connected to the driven sprocket B1002 via a chain B1003. This drives the seed-collecting mechanism B7 to operate.

[0041] The synchronous multi-stage gear transmission mechanism 11 includes a driving gear 1101, a driven gear 1102, and multiple intermediate gears 1103. The driving gear 1101 is located at the left end of the loading main shaft 301 of the upright loading mechanism B4, and the driven gear 1102 is located at the left end of the loading main shaft 301 of the upright loading mechanism A3. The driving gear 1101 meshes with the driven gear 1102 through multiple intermediate gears 1103. The intermediate gears are mounted on the frame 1 through an intermediate rotating shaft 1104 and a bearing seat. This mechanism enables the upright loading mechanism A3 to operate while ensuring stable and reliable power transmission and good synchronization.

[0042] The synchronous reverse transmission mechanism 12 includes two bevel gears A1201 respectively disposed at the right end of the seed-collecting main shaft 608. Each bevel gear A1201 is connected to a bevel gear B1202. The two bevel gears B1202 are connected by a transmission rod 1203. The bevel gears A1201 and B1202 are disposed on a bevel gear seat 1204. This mechanism drives the seed-collecting mechanism A3 to operate, and the operating direction of the seed-collecting mechanism A3 is opposite to the operating direction of the seed-collecting mechanism B4.

[0043] The rotary tillage mechanism 2 includes a rotary tillage main shaft 201, with both ends of the main shaft 201 rotatably mounted on the frame 1 via bearing seats. Multiple cutter head seats 202 are spaced apart along the length of the main shaft 201, and multiple rotary tillage blades 203 are spaced apart along the circumference of each cutter head seat 202. The rotary tillage main shaft 201 is connected to the agricultural machinery 9 (existing technology) via a transmission box and a gearbox. This mechanism loosens the soil, facilitating cultivation.

[0044] A method for planting garlic with smaller plant spacing, including the garlic planting device with smaller plant spacing as described above, assuming the required plant spacing is L cm, then the plant spacing of the upright planting mechanism A3 and the upright planting mechanism B4 is set to 2L cm, and the distance between the upright planting mechanism A3 and the upright planting mechanism B4 is set to S cm. The expression for S is as follows:

[0045] S=(2L)×N+L

[0046] In the formula, N is a positive integer, and the value of N must ensure that the vertical lowering mechanism A3 and the vertical lowering mechanism B4 do not interfere with each other;

[0047] During sowing, a garlic planting device with smaller plant spacing is installed on the agricultural machinery via frame 1. The agricultural machinery drives the rotary tillage mechanism 2 to till the land. The rotation of the press wheel 502 drives the press shaft 501 to rotate. The press shaft 501 drives the upright planting mechanism B4 through chain drive A9. The upright planting mechanism B4 drives the seed picking mechanism B7 through chain drive B10 and drives the upright planting mechanism A3 through synchronous multi-stage gear transmission mechanism 11. The seed picking mechanism B7 drives the seed picking mechanism A6 through synchronous reverse transmission mechanism 12. The seed picking spoons 605 on the seed picking mechanisms A6 and B7 respectively pick up seeds from the seed box 8 and send the garlic seeds into the corresponding receiving duckbill 607. The upright planting mechanism A3... During the rotation of the upright planting mechanism B4, the planting duckbill 306 opens the receiving duckbill 607, allowing the garlic cloves in the receiving duckbill 607 to fall into the planting duckbill 306. The planting duckbill 306 remains upright during rotation by rotating on its own. When the planting duckbill 306 rotates to the planting position, it opens under the action of the opening and closing drive disc 309 and the collision roller 308, planting the garlic cloves into the soil for complete sowing. Through continuous operation, garlic sowing can be completed without interruption. The spacing design between the upright planting mechanism A3 and the upright planting mechanism B4 ensures that the planting position B14 of the upright planting mechanism B4 is located between the two adjacent planting positions A13 of the upright planting mechanism A3, ultimately achieving sowing with a smaller plant spacing.

[0048] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0049] Any aspects of this utility model not described in detail are known to those skilled in the art.
