Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a sowing machine for intercropping corn and legume green manure. Background Technology

[0002] To improve moderately saline-alkali soil, corn and legume green manure need to be interplanted as shown in the diagram, where X represents corn and O represents legume green manure. To achieve this planting method, the two crops need to be interplanted within the same planting row. In the prior art, for seeds such as corn and soybeans, a spoon-wheel type seed metering device, as shown in patent CN202799630U, is mainly used for seed metering. In addition, regarding the problem of interplanting in the same row, patents CN105532140A and CN105638043A disclose seed metering machines suitable for interplanting two crops in the same row. These patents disclose a method for interplanting two crops in the same row using a seed metering wheel with a seed metering groove on a partially curved section and a seed guiding device. However, this patent requires remolding the seed metering structure and using a seed guiding device to guide the interplanting in the same row, resulting in a complex overall structure and high manufacturing costs.

[0003] This application aims to modify existing seed metering devices to enable the interplanting of two types of seeds in the same planting row at a lower cost. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a sowing machine that modifies the existing seed metering device to realize the interplanting of two kinds of seeds and achieves interplanting of corn and legume green manure at low cost.

[0005] Technical solution: To achieve the above objectives, the present invention provides a sowing machine for intercropping corn and legume green manure, which includes a corn seed box, a corn seeding mechanism, a legume green manure seed box, and a legume green manure seeding mechanism.

[0006] The corn seeding mechanism includes a first seeding wheel and a first end shell. The end face of the first seeding wheel has a plurality of first seeding structures arranged in a circumferential array. A corn seed accommodating space is formed between the first seeding wheel and the first end shell, and the first end shell has a first seed inlet tube.

[0007] The legume green manure seeding mechanism includes a second seeding wheel and a second end shell. The end face of the second seeding wheel has a plurality of second seeding structures arranged in a circumferential array. A seed-accommodating space for legume green manure is formed between the second seeding wheel and the second end shell, and the second end shell has a second seed inlet tube.

[0008] The first seeding wheel rotates synchronously with the second seeding wheel;

[0009] The corn sorting mechanism also includes a first sector-shaped partition fixed on the first sorting wheel, which blocks multiple first sorting structures within its arc segment range;

[0010] The legume green manure sowing mechanism also includes a second sector-shaped partition fixed on the second sowing wheel, which blocks multiple second sowing structures within its arc segment.

[0011] The angle range covered by the first sector-shaped partition in the rotation direction of the first seeding wheel is staggered from the angle range covered by the second sector-shaped partition in the rotation direction of the second seeding wheel, and the sum of the angle ranges covered by the two sector-shaped partitions in the rotation direction of their respective seeding wheels is 360°.

[0012] In this way, at the same time, only one of the corn seeding mechanism and the legume green manure seeding mechanism is discharging seeds, which can achieve staggered seeding of corn seeds and legume green manure seeds in a planting row. That is, a set number of corn seeds are discharged first, then a set number of legume green manure seeds are discharged, then a set number of corn seeds are discharged, and so on.

[0013] In this application, by setting a first sector-shaped partition and a second sector-shaped partition, the existing seed metering device can be modified to quickly realize the interleaving planting of two kinds of seeds in a planting row. Compared with the prior art, the cost of this invention is very low and the modification is convenient.

[0014] Furthermore, in the first embodiment, the corn seeding mechanism and the legume green manure seeding mechanism are arranged in a front-to-back configuration, and the drive shafts of the first seeding wheel and the second seeding wheel are connected by a synchronization mechanism. The synchronization mechanism can be a timing belt assembly, a chain assembly, etc. In this scheme, both the corn seeding mechanism and the legume green manure seeding mechanism are based on a modified spoon-and-plate seed metering device. Both the first and second seeding structures are seed-scooping spoons. Both the corn seeding mechanism and the legume green manure seeding mechanism are based on a grooved wheel with a seed-filling groove arranged in a circular array for seed metering. Taking the corn seeding mechanism as an example, a partition is set between the first seeding wheel and the grooved wheel. The first seeding wheel and the grooved wheel rotate synchronously. A connecting groove is set on the upper edge of the partition. The first seeding structure takes seeds from the bottom of the corn seed holding space. The partition keeps the seeds in the seed-scooping groove. When the seeds reach the connecting groove, they slide from the seed-scooping groove into the seed-filling groove of the grooved wheel. The grooved wheel carries the seeds to the seed outlet for discharge. In the above structure, when the unobstructed first seeding structure reaches the connecting groove, seeds enter the corresponding seed-filling groove. When the obstructed first seeding structure reaches the connecting groove, no seeds enter the corresponding seed-filling groove. The seed-filling groove is empty from the connecting groove to the seed outlet. The legume green manure seed dispensing mechanism also has grooved wheels and partitions for use, and its seed dispensing process is the same as that of corn seeds described above, so it will not be described in detail here. In this scheme, two spoon-shaped seed dispensers are arranged in a front-to-back configuration, making it simple to use.

[0015] Furthermore, in the second scheme, the first and second seeding wheels are coaxially mounted, and both the first and second seeding structures are seed-scooping scoops. A grooved wheel is installed between the first and second seeding wheels, and the edge of the grooved wheel forms multiple seed-filling grooves arranged in a circular array. Seeds can enter from both sides of the seed-filling grooves. The first, second, and grooved wheels rotate synchronously. Partitions are installed between the first and second seeding wheels and the grooved wheel, respectively. A connecting groove is provided on the upper edge of the partition, and the connecting grooves on the two partitions are aligned. Using this structure, the corn seeding mechanism and the legume green manure seeding mechanism both use the same grooved wheel for seeding, which greatly improves the compactness of the structure and reduces the required installation space. Compared to the first scheme, it effectively reduces the front-to-back length of the machine and improves its flexibility.

[0016] In actual operation, because the angles covered by the two fan-shaped partitions are staggered, when the first seeding structure, which is not obstructed, reaches the connecting groove, the corn seeds inside it enter the corresponding seed filling groove through the connecting groove. At this time, the second seeding structure on the other side of the groove wheel is obstructed by the second fan-shaped partition. When the second seeding structure, which is not obstructed, reaches the connecting groove, the legume green manure seeds inside it enter the corresponding seed filling groove through the connecting groove. At this time, the first seeding structure on the other side of the groove wheel is obstructed by the second fan-shaped partition. In this way, the seed filling grooves in a part of the arc segment of the groove wheel are filled with corn seeds, and the seed filling grooves in the other part of the arc segment are filled with legume green manure seeds. The groove wheel can be fully utilized, and there will be no situation where empty seed filling grooves move from the connecting groove to the seed outlet.

[0017] Furthermore, the sowing machinery also includes a furrow opener positioned between the corn sowing mechanism and the legume green manure sowing mechanism.

[0018] Furthermore, the seeding machinery also includes a soil covering mechanism located after both the corn seeding mechanism and the legume green manure seeding mechanism.

[0019] Beneficial effects: The sowing machinery of the present invention for intercropping corn and legume green manure has the following beneficial effects:

[0020] (1) By setting the first sector partition and the second sector partition, the existing seed metering device is modified so that only one of the corn seeding mechanism and the legume green manure seeding mechanism is discharging seeds. This allows for staggered seeding of corn seeds and legume green manure seeds in a planting row. Compared with the prior art, the cost of this invention is very low and the modification is convenient.

[0021] (2) In the embodiment where the corn seeding mechanism and the legume green manure seeding mechanism share the same grooved wheel, the seed filling groove in one arc segment of the grooved wheel can be filled with corn seeds, while the seed filling groove in another arc segment can be filled with legume green manure seeds. This fully utilizes the grooved wheel and prevents empty seed filling grooves from moving from the connecting groove to the seed outlet. The corn seeding mechanism and the legume green manure seeding mechanism use the same grooved wheel for seed dispensing, which greatly improves the compactness of the structure and reduces the required installation space. Compared to the first embodiment, this effectively reduces the front-to-back length of the machine and improves its flexibility. Attached Figure Description

Detailed Implementation

[0033] The invention will now be further described with reference to the accompanying drawings.

[0034] like Figure 2 As shown, the sowing machinery of the present invention for intercropping corn and legume green manure includes a corn seed box 1, a corn seeding mechanism 2, a legume green manure seed box 3, and a legume green manure seeding mechanism 4; it also includes a furrow opener 8 placed in front of the corn seeding mechanism 2 and the legume green manure seeding mechanism 4, and a soil covering mechanism 5 placed behind the corn seeding mechanism 2 and the legume green manure seeding mechanism 4.

[0035] like Figure 3-4As shown, the corn seeding mechanism 2 includes a first seeding wheel 21 and a first end shell 22. The end face of the first seeding wheel 21 has a plurality of first seeding structures 21a arranged in a circumferential array. A corn seed accommodating space is formed between the first seeding wheel 21 and the first end shell 22, and the first end shell 22 has a first seed inlet tube 23.

[0036] The legume green manure seeding mechanism 4 includes a second seeding reel 41 and a second end shell 42, such as Figure 5 As shown, the second seeding wheel 41 has multiple second seeding structures 41a arranged in a circular array on its end face; a seed-holding space for legume green manure is formed between the second seeding wheel 41 and the second end shell 42, and the second end shell 42 has a second seed inlet tube 43. The first seeding wheel 21 and the second seeding wheel 41 rotate synchronously.

[0037] The corn sowing mechanism 2 further includes a first sector-shaped partition 24 fixed on the first sowing wheel 21, which blocks multiple first sowing structures 21a within its arc segment; the legume green manure sowing mechanism 4 further includes a second sector-shaped partition 44 fixed on the second sowing wheel 41, which blocks multiple second sowing structures 41a within its arc segment; Figure 4 With appendix Figure 5 As shown, the angle range covered by the first sector-shaped partition 24 in the rotation direction of the first seeding wheel 21 is offset from the angle range covered by the second sector-shaped partition 44 in the rotation direction of the second seeding wheel 41, and the sum of the angle ranges covered by the two sector-shaped partitions in the rotation direction of their respective seeding wheels is 360°.

[0038] In this way, at the same time, only one of the corn seeding mechanism 2 and the legume green manure seeding mechanism 4 is discharging seeds, which can achieve staggered seeding of corn seeds and legume green manure seeds in a planting row. That is, a set number of corn seeds are discharged first, then a set number of legume green manure seeds are discharged, then a set number of corn seeds are discharged, and so on.

[0039] In this application, the existing seed metering device is modified by setting a first sector-shaped partition 24 and a second sector-shaped partition 44, which can quickly realize the interleaving planting of two kinds of seeds in a planting row. Compared with the prior art, the cost of this invention is very low and the modification is convenient.

[0040] In the first embodiment, such as Figure 2 As shown, the corn seeding mechanism 2 and the legume green manure seeding mechanism 4 are arranged in a front-to-back configuration, and the drive shafts of the first seeding wheel 21 and the second seeding wheel 41 are connected by a synchronization mechanism. The synchronization mechanism can be a timing belt assembly, a chain assembly, etc. Figure 4and Figure 6 In the illustrated embodiment, both the corn seeding mechanism 2 and the legume green manure seeding mechanism 4 are based on a modified spoon-and-plate seed metering device. Both the first seeding structure 21a and the second seeding structure 41a are seed-scooping spoons. Both the corn seeding mechanism 2 and the legume green manure seeding mechanism 4 use a grooved wheel 6 with a seed-filling groove 61 arranged in a circular array for seed metering. Taking the corn seeding mechanism 2 as an example, a partition 7 is provided between the first seeding wheel 21 and the grooved wheel 6. The first seeding wheel 21 and the grooved wheel 6 rotate synchronously. A connecting groove 71 is provided on the upper edge of the partition 7. The first seeding structure 21a takes seeds from the bottom of the corn seed-containing space, and the partition 7 keeps the seeds within the seed-scooping groove. Figure 7 As shown, when the first seeding structure 21a reaches the connecting groove 71, corn seeds can slide from the seed scooping groove into the filling groove 61 of the groove wheel 6. The groove wheel 6 carries the seeds to the seed outlet a for discharge. In the above structure, when the unobstructed first seeding structure 21a reaches the connecting groove 71, seeds enter the corresponding filling groove 61. When the obstructed first seeding structure 21a reaches the connecting groove 71, no seeds enter the corresponding filling groove 61, and the filling groove 61 is empty from the connecting groove 71 to the seed outlet. The legume green manure seeding mechanism 4 also has a groove wheel 6 and a partition 7 used in conjunction with it. Its seed dispensing process is the same as the corn seed dispensing process described above, and will not be described in detail here. In this embodiment, the two scoop-plate seed dispensers are arranged in a front-to-back manner, which is simple to use.

[0041] In the second embodiment, such as Figure 8 As shown, the first seeding wheel 21 and the second seeding wheel 41 are coaxially mounted, and both the first seeding structure 21a and the second seeding structure 41a are seed scoops; a grooved wheel 6 is installed between the first seeding wheel 21 and the second seeding wheel 41, and the edge of the grooved wheel 6 forms multiple seed filling grooves 61 arranged in a circular array. Seeds can enter from both sides of the seed filling grooves 61. The first seeding wheel 21, the second seeding wheel 41, and the grooved wheel 6 rotate synchronously; partitions 7 are respectively installed between the first seeding wheel 21 and the second seeding wheel 41 and the grooved wheel 6; the upper edge of the partition 7 is provided with a connecting groove 71, and the connecting grooves 71 on the two partitions 7 are aligned. With this structure, the corn seeding mechanism 2 and the legume green manure seeding mechanism 4 can both seed through the same grooved wheel 6, which can greatly improve the compactness of the structure and reduce the required installation space. Figure 9 As shown, compared to the first embodiment, the front and rear length of the machine can be effectively reduced, and the flexibility of the machine can be improved.

[0042] In actual operation, because the angles covered by the two fan-shaped partitions are staggered, when the unobstructed first seeding structure 21a reaches the connecting groove 71, the corn seeds inside it enter the corresponding seed filling groove 61 through the connecting groove 71. At this time, the second seeding structure 41a on the other side of the groove wheel 6 is blocked by the second fan-shaped partition 44; when the unobstructed second seeding structure 41a reaches the connecting groove 71, the legume green manure seeds inside it enter the corresponding seed filling groove 61 through the connecting groove 71. At this time, the first seeding structure 21a on the other side of the groove wheel 6 is blocked by the second fan-shaped partition 44; thus, as... Figure 10 As shown, the seed filling groove 61 in one part of the arc segment of the groove wheel 6 can be filled with corn seeds, while the seed filling groove 61 in another part of the arc segment can be filled with legume green manure seeds. This makes full use of the groove wheel 6 and prevents the empty seed filling groove 61 from moving from the connecting groove 71 to the seed outlet a.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
