Description

Technical Field

[0001] The utility model relates to the field of crop sowing, in particular to a seeder used for intercropping of forage crops. Background Art

[0002] Intercropping refers to a sowing pattern that rationally utilizes the three-dimensional space for crop sowing and plants two or more crops in the same sowing row at a certain spacing and density. Existing technologies have shown that rationally matching crops with different plant heights, slightly different growth periods, and significantly different growth characteristics can improve the utilization of light energy, soil, and field space, help improve planting results, and promote increased production and income.

[0003] At present, intercropping of silage corn and soybeans is mostly done by using corn seeders and soybean seeders alone, that is, corn or soybeans are planted first, and then soybeans or corn are planted on the land left between the rows of corn or soybeans to achieve intercropping. This sowing method not only has low operating efficiency, high operating costs, and a long operating cycle, but also repeatedly rolling will damage the land and is difficult to operate and control.

[0004] To this end, the present application has developed a seeder that can realize intercropping through research and development. Summary of the invention

[0005] In order to solve the above problems, the utility model provides a seeder for intercropping of forage crops. The seeder can be used with a traction device to simultaneously intercrop at least two different crops, and has the characteristics of reasonable and compact structure, strong applicability for intercropping, easy operation, high sowing efficiency, etc. The seeder can give full play to the advantages of intercropping and is conducive to the application and promotion of the intercropping planting mode.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A seeder for intercropping of forage crops, comprising

[0008] A seed box, wherein the seed box is provided with at least two seed cavities, wherein different crop seeds are contained; a disturbance disk is provided at the bottom of the seed cavity, and the disturbance disk is connected to the seed cavity through a hollow disturbance shaft, and a disturbance blade is installed on the disturbance shaft;

[0009] The lower end of the hollow disturbance shaft of the disturbance disk is connected to a seeding tube, and the end of the seeding tube extends to the top of the seeding wheel;

[0010] At least two seeding wheels are coaxially arranged, respectively located below corresponding seeding tubes and rotating synchronously;

[0011] The wheel surface of the sowing wheel is provided with a plurality of seeding grooves in the radial direction, and the seeding grooves are connected to a seed receiving cavity arranged inside the sowing wheel, that is, the number of the seeding grooves is the same as that of the seed receiving cavity, and the seed receiving cavity is provided with a spherical bottom; different sowing wheels have different orientations of the seeding grooves and the seed receiving cavity, that is, the distribution in the axial direction does not overlap;

[0012] The seeding wheel is fixedly mounted on the rotating shaft I, and reversing gears are mounted on both ends of the rotating shaft I. The reversing gears are connected to the corresponding disturbance disk through a transmission shaft and drive the corresponding disturbance disk to rotate;

[0013] The rotating shaft I is synchronously driven by the rotating shaft II, and traveling wheels are installed at both ends of the rotating shaft II.

[0014] When the seeder is pulled forward, it drives the rotating shaft I to rotate, and then drives the disturbance disk and the seeding wheel to rotate. When the disturbance disk rotates, the seeds inside it are disturbed and continuously discharged from the bottom hollow disturbance shaft and enter the seed discharge tube below. When the seeding wheel rotates to the point where its seed drop groove is at the 12 o'clock position, the seed discharge tube is connected to the seed drop groove accordingly, and the seeds inside it fall into the seed receiving cavity and continue to rotate with the seeding wheel; the seed receiving cavity has a spherical bottom that can be used to carry seeds and rotate with it. When it rotates to the 7-8 o'clock position of the seeding wheel, the seeds inside it will slide into the open furrow of the seeding row below.

[0015] As an improvement of the above technical solution, the seed box is provided with two seed chambers, and the seeding wheels are coaxially provided with two;

[0016] One of the seeding wheels has two seed placement grooves on its wheel surface in the diameter direction;

[0017] Another seeding wheel has three groups, i.e. six seed placement grooves, formed on its wheel surface in the diameter direction;

[0018] The seeding grooves of the two seeding wheels are not distributed in the axial direction.

[0019] As an improvement of the above technical solution, one of the seeding wheels has two seed placement grooves at the 12 o'clock direction and the 6 o'clock direction on its wheel surface;

[0020] Another seeding wheel has three groups, i.e. six seed placement grooves, on its wheel surface in the 3 o'clock direction and in the diameter direction of the positive and negative 45° directions.

[0021] As an improvement of the above technical solution, an inoculation bucket is provided on the top of the seed discharge tube.

[0022] As an improvement of the above technical solution, a movable baffle is provided at the bottom of the seeding tube, and the movable baffle is mounted on the wheel surface of the seeding wheel in a natural state;

[0023] When the seeding wheel rotates until its seeding groove is at the 12 o'clock position, the movable baffle loses support and opens, the seeding tube is connected to the seeding groove, and the seeds in the seeding tube fall into the seeding groove; when the seeding wheel continues to rotate until the movable baffle touches the right notch of the seeding groove, it is supported again and is re-mounted on its wheel surface as the seeding wheel rotates.

[0024] As an improvement of the above technical solution, the diameter of the seed discharge tube is slightly larger than the diameter of the seed drop groove to avoid too many seeds being discharged at a single time.

[0025] As an improvement of the above technical solution, the bottom of the seed cavity is spherical.

[0026] As an improvement of the above technical solution, a bearing seat is installed on the rotating shaft I between the seeding wheels, the upper end of the bearing seat is provided with a support rod supported on the bottom of the seed box, and the lower end is provided with a connecting rod connected to the rotating shaft II.

[0027] As an improvement of the above technical solution, the rotating shaft I and the rotating shaft II are staggered, that is, they are not located on the same horizontal and vertical planes.

[0028] Beneficial effects brought by the utility model:

[0029] The seeder of the utility model has a reasonable and compact structure, and the working principle is simple, easy to understand and use. It can be easily combined with traction equipment to realize the intercropping of at least two different crops, thereby giving full play to the advantages of intercropping, which is very conducive to the promotion of the intercropping planting mode.

[0030] Based on this seeder, intercropping two or more crops in the same row can achieve many benefits. For example, when silage corn and laba beans are intercropped in the same row at the same time, when the corn sowing wheel rotates one circle, the laba bean sowing wheel rotates one circle synchronously. At this time, two holes of corn are sown, and three holes of laba beans are sown evenly in between. During the crop production period, laba beans can grow on corn. At the same time, this planting mode is conducive to mechanical fertilization and weeding operations, and can also effectively reduce the cross-row winding resistance of laba beans during mechanical harvesting.

[0031] In addition, when intercropping crops based on this seeder, the following effects can be achieved:

[0032] It is more conducive to ventilation and light transmission in multiple directions in the field, and the ventilation and light transmission conditions of crops are better;

[0033] Planting crops with complementary effects closer together can help improve soil spatial utilization;

[0034] Intercropping has strong applicability, high sowing efficiency, and is economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the embodiments of the utility model and the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example 1

[0041] Reference Figure 1 , a seeder for intercropping of forage crops, comprising

[0042] A seed box 1, wherein the seed box 1 is provided with two seed chambers, wherein different crop seeds are contained, and the crop seeds should be seeds of relatively uniform specifications after screening; a disturbance disk 2 is provided at the bottom of the seed chamber, which is mainly used to disturb the seeds in the seed chamber, so that the seeds can enter the hollow disturbance shaft more easily under the disturbance and be discharged, while avoiding accumulation and blockage; the disturbance disk 2 is connected to the bottom position of the seed chamber through the hollow disturbance shaft at the axis center, and two disturbance blades are installed on the disturbance shaft, and the blades are wrapped with soft materials to avoid damaging the seeds;

[0043] The lower end of the hollow disturbance shaft of the disturbance disk 2 is connected to a seeding tube 3, and an inoculation bucket is provided at the top of the seeding tube 3 to prevent seeds from scattering due to impact. The end of the seeding tube 3 extends to the top of the sowing wheel 4;

[0044] The sowing wheels 4 are coaxially arranged with two of them, which are respectively located below the corresponding seeding tubes 3 and rotate synchronously. To adapt to the position of the sowing wheels 4, the seeding tubes 3 are metal seed slideways with smooth inner walls and inclined inwards.

[0045] The wheel surface of the seeding wheel 4 is provided with a plurality of seeding grooves 41 in the radial direction, and the seeding grooves 41 are connected to the seed receiving chamber 42 provided inside the seeding wheel 4, that is, the number of the seeding grooves 41 and the seed receiving chamber 42 is the same, and the upper end of the seed receiving chamber 42 is connected to the inner end notch of the seeding groove 41, and it is provided with a spherical bottom to carry crop seeds through a smooth spherical surface. Different seeding wheels 4 have the same or different numbers of seeding grooves 41 and seed receiving chambers 42, but their distribution in the same axial perspective does not overlap;

[0046] The seeding wheel 4 is fixedly mounted on the rotating shaft I5, and reversing gears 6 are installed at both ends of the rotating shaft I5. The reversing gears 6 are actually transmission gear sets, which convert the axial power of the rotating shaft I5 to the vertical direction through gear transmission, and further transmit its power to the disturbance disk 2 on the corresponding side through the transmission shaft, and then drive it to rotate through the gears;

[0047] The rotating shaft I5 is synchronously driven by the rotating shaft II7, and traveling wheels 8 are installed at both ends of the rotating shaft II7.

[0048] The seeder itself has no power source and needs external traction equipment, such as an agricultural tractor, a tricycle, etc., when in use. The various components achieve intercropping of two different crops through coordinated action.

[0049] When the seeder is pulled forward, it drives the rotating shaft I5 to rotate, and then drives the disturbance disk 2 and the seeding wheel 4 to rotate. When the disturbance disk 2 rotates, the seeds therein are disturbed and continuously discharged from the bottom hollow disturbance shaft and enter the seed discharge tube 3 below. When the seeding wheel 4 rotates to the point where its seed drop groove 41 is located at the 12 o'clock position, when the left side of the seed discharge tube 3 is aligned with the left side of the notch of the seed drop groove 41, the seed discharge tube 3 is now correspondingly connected to the seed drop groove 41, and the seeds therein fall into the seed receiving chamber 42 and continue to rotate with the seeding wheel 4; the seed receiving chamber 42 has a spherical bottom that can be used to carry seeds and rotate with it. When it rotates to the 7-8 o'clock position of the seeding wheel 4, the seeds therein will slide into the open furrow of the seeding row below.

[0050] As an improvement of this embodiment, the bottom of the seed cavity is spherical, which is conducive to seed discharge.

[0051] As an improvement of this embodiment, a bearing seat is installed between the seeding wheels 4 on the rotating shaft I5. The upper end of the bearing seat is provided with a support rod supported on the bottom of the seed box 1, and the lower end is provided with a connecting rod connected to the bearing seat on the rotating shaft II7. This design makes the seed metering structure more stable.

[0052] As an improvement of this embodiment, the rotating shaft I5 and the rotating shaft II7 are staggered, that is, they are not located on the same horizontal and vertical planes.

[0053] Example 2

[0054] A seeder for intercropping silage corn and laba beans, the seeder being different from embodiment 1 in that:

[0055] Reference Figure 2 , Figure 5 There are two coaxially arranged seeding wheels 4, one of which has two seeding grooves 41 on its wheel surface at the 12 o'clock direction and the 6 o'clock direction; the other seeding wheel 4 has three groups of six seeding grooves 41 on its wheel surface at the 3 o'clock direction and the diameter direction at the positive and negative 45° directions, so that the distribution of each seeding groove 41 and the seed receiving cavity 42 in the same axial viewing angle does not overlap.

[0056] The seeder of this embodiment can intercrop silage corn and laba beans at the same time. When the corn seeding wheel 4 rotates one circle, the laba bean seeding wheel 4 rotates one circle synchronously. At this time, corn is planted in two holes, and three holes of laba beans are evenly planted in between.

[0057] During the sowing process, a movable baffle 31 is provided at the bottom of the seeding tube 3. The movable baffle 31 is naturally mounted on the wheel surface of the sowing wheel 4. A small gap between the movable baffle 31 and the opening of the seeding tube 3 does not affect the sealing effect. Figure 3 When the seeding wheel 4 rotates until its seeding groove 41 is located at the 12 o'clock position, the movable baffle 31 begins to lose support and gradually opens. In a short period of time, the seeding tube 3 is connected with the seeding groove 41, so that the seeds in the seeding tube 3 fall into the seeding groove 41 due to gravity and then enter the seed receiving chamber 42. When the seeding wheel 4 continues to rotate until the movable baffle 31 touches the right notch of the seeding groove 41, it is supported again and starts to move upward, and is re-mounted on its wheel surface as the seeding wheel 4 rotates, while closing the pipe mouth of the seeding tube 3.

[0058] The seeds are located in the seed receiving chamber 42 and continue to rotate with the sowing wheel 4. The shape of the seed receiving chamber 42 is similar to a light bulb, and has a spherical bottom that can be used to carry the seeds and rotate with it. Figure 4 This design ensures that only when the sowing wheel 4 is rotated to the direction between 7 and 8 o'clock, the seeds inside it will slide out and be sown in the furrow below.

[0059] In this embodiment, the diameter of the seeding tube 3 is slightly larger than the diameter of the seeding slot 41. At the same time, the seeding slot 41 is approximately a right-angled trapezoid, and its right notch is slightly inclined to the right, so as to ensure the basic seeding number while avoiding too many seeds at a time. It should be noted that the traction equipment needs to maintain a reasonable traction speed, and its range is easy to obtain based on experiments.

[0060] In this embodiment, since the circumference of the seeding wheel 4 is fixed, and the orientation of each seed receiving cavity 42 on the seeding wheel 4 is known and can be set as needed, through reasonable size design, the device can make the two seeding wheels 4 sow forage seeds at a specified interval to give full play to the advantages of intercropping.

[0061] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
