Description

Technical Field

[0001] This utility model relates to the field of agricultural production equipment technology, and in particular to a sowing device for intercropping peanuts with cotton. Background Technology

[0002] Intercropping in strips is a very common cultivation method, and peanuts, cotton, or corn are commonly planted on saline-alkali land. The traditional method involves planting one crop first, reserving a strip, and then sowing the other crop. This double sowing not only wastes manpower and resources but also damages the first crop. Existing sowing devices can sow two types of seeds simultaneously, but these devices use a single-size seed metering wheel and an integrated cavity. The circumferential seed bin size of the seed metering wheel is fixed, while cotton and peanut seeds differ significantly in size and morphology. The seed metering wheel cannot accommodate both types of seeds simultaneously. If the bin is designed for peanut seeds, cotton seeds are prone to being missed or unevenly sown; conversely, peanut seeds are prone to getting stuck and obstructed. Because intercropping cotton and peanuts requires adjusting the number of rows of cotton and peanut seeds between them based on soil and sunlight conditions, the fixed size of the seed metering wheels in existing sowing devices cannot be adjusted according to soil and sunlight conditions. For example, a novel cotton planter disclosed in patent application number CN202321396693.1 can only sow cotton seeds in multiple rows. When faced with multiple seeds that need to be intercropped, the device cannot complete the intercropping process. When peanut or corn seeds are planted, the size of the sowing groove on the seed metering wheel is larger or smaller than the seed size, which makes it impossible to complete the intercropping of different seeds.

[0015] like Figure 1 The device shown is a seeding device for intercropping peanuts with cotton, comprising: a frame 1, a seed box 2 mounted on the frame 1 via a mounting bracket, the seed box 2 having multiple independent cavities inside, a furrowing assembly located at the front end of the frame 1 and below the frame 1, a soil covering assembly located at the rear end of the frame 1 and below the frame 1, and further comprising: a seed metering mechanism located below the seed box 2 and cooperating with each cavity, the seed metering mechanism comprising: a seed metering box 5 adapted to each cavity, and a seeding hose 6 communicating with the interior of each seed metering box 5 and extending to the bottom of the frame 1; The rotating device is mounted on the frame 1 and passes vertically through the rotating shaft 7 of each seed box 5; Each seed metering box 5 has at least two feeding chambers formed by a partition 12. Each feeding chamber is equipped with a seed metering wheel 10 connected to a rotating shaft 7. The number and size of the sowing grooves 14 on the two seed metering wheels 10 in each seed metering box 5 are different to accommodate different seeds.

[0016] Working principle: During operation, cotton seeds and peanut seeds are simultaneously loaded into the corresponding cavities of the seed box 2 according to the needs of intercropping in different lands. The cotton and peanut seeds then enter the different feeding cavities of the seed metering box 5. Subsequently, the rotating shaft 7 rotates, synchronously driving the seed metering wheels 10 mounted on it to rotate. Since the number and size of the sowing grooves 14 on the two seed metering wheels 10 are different, they are adapted to the different spacing between the holes for peanut and cotton seeds. The discharged seeds enter the sowing hoses 6 connected to the seed metering box 5. The seeds fall precisely from the sowing hoses 6 into the pre-drilled furrows of the furrowing component located at the front. Finally, the soil covering component at the rear of the frame 1 covers the furrows with soil, completing the integrated sowing operation for cotton and peanut intercropping. This device can achieve sowing of different seed materials in the same cavity, adapting to different regions, soil types, and different intercropping patterns.

[0017] In the above technical solution, each cavity is internally constructed with partition plates 12 to form cavity I and cavity II, which are connected to the corresponding feeding cavity. With this technical solution, when partition plates 12 are not set, baffles (not shown in the figure) need to be set at the discharge port where the two feeding cavities are connected to the cavity of seed box 2 to prevent the two types of seeds from entering other seed dispensing wheels 10. With the separation of partition plates 12, baffles are no longer required, and the materials in cavity I and cavity II can also fall off, so the seeds will not remain in the cavity of seed box 2. During each intermittent operation, only one of the chambers, chamber I or chamber II, contains material.

[0018] In the above technical solution, the furrowing component includes: a furrow opener 4 group slidably mounted on the frame 1 via a T-shaped connector 3 and cooperating with the seeding hose 6. The furrow opener 4 group includes: multiple furrow openers 4 slidably mounted on the crossbar 62 of the T-shaped connector 3. The T-shaped connector 3 has multiple positioning holes 31 along its height direction. The T-shaped connector 3 is detachably connected to the frame 1 by connecting bolts passing through the frame 1 and the positioning holes 31. Each seeding hose 6 is slidably mounted on the crossbar 62 below the frame 1 by mounting parts 61. Mounting component 61 is fixed to crossbar 62 by connecting bolts. The front end of mounting component 61 has mounting holes 63 for the sowing hose 6 to pass through. With this technical solution, the multiple positioning holes 31 along the height direction of the vertical rod of the T-shaped connector can flexibly change the overall height of the furrow opener group 4 by adjusting the position of the positioning holes 31 through which the connecting bolts pass, and adjust different furrowing depths. Each furrow opener 4 can be slidably mounted on the crossbar 62 of the T-shaped connector 3. Combined with the sowing hose 6 being inserted into the mounting hole 63 and slidingly adjusted on the crossbar 62 (while the crossbar 62 has multiple through holes, and the connecting end 41 is provided with a pin extending into the through hole), the lateral position of the furrow opener 4 can be synchronously matched with the row spacing adjustment of the sowing hose 6, ensuring that under different intercropping modes (such as 2 cotton 2 peanut or 3 cotton 1 peanut), the furrowing position accurately corresponds to the subsequent sowing hose 6's seed placement position, preventing the seeds from deviating from the seed furrow.

[0019] The attached diagram of the device shows only four cavities for the seed box 2. In actual operation, the length of the seed box 2 can be increased to increase the number of internal cavities, which can accommodate crops with different number of rows. At the same time, the number of seed metering boxes 5 and furrow openers 4 also changes accordingly. The frame is equipped with a drive motor 8 for rotating the shaft.

[0020] In the above technical solution, the soil covering assembly includes a soil covering roller 9, which is rotatably mounted on the frame 1 and rolls the soil after sowing. Using this technical solution, the soil covering roller 9, through rotation, compacts the soil after furrowing, causing the soil to cover the seed surface and maintain close contact with the seeds.

[0021] In the above technical solution, the furrow opener 4 includes: a connecting end 41 slidably connected to the crossbar 62, and a plow blade 42 disposed below the connecting end 41. The plow blade 42 is threadedly connected to the connecting end 41 via a connecting post. Using this technical solution, firstly, the positions of the furrow openers 4 at both ends of the crossbar 62 of the T-shaped connector 3 are fixed to ensure that the overall furrowing distance does not change. Secondly, when changing the intercropping mode, the positions of the seeding hose 6 and the furrow opener 4 in the middle position can be adjusted to adapt to different intercropping modes. The furrow opener 4 is designed as a separate unit through the connecting end 41 and the plow blade 42, which allows for easy adjustment as needed (if intercropping is not used in a certain planting, and all plants are cotton, and the pre-set number of furrow openers 4 is adapted to the intercropping mode, the plow blade 42 can be removed from the connecting end 41, and the spacing between the remaining furrow openers 4 can be adjusted). This also makes it more adaptable to various different planting methods.

[0022] The above technical solution also includes: a brush 11 disposed on one side wall of each feeding chamber and adapted to the corresponding seed metering wheel 10; wherein, the brush 11 is located on the side wall of the sowing groove 14 in the rising state, and the shape of each feeding chamber on the descending side of the sowing groove 14 is adapted to the size of the seed metering wheel 10. Using this technical solution, during the rotation of the seed metering wheel 10, seeds may adhere to the wheel surface due to factors such as humidity and static electricity. The continuous cleaning by the brush 11 can break this adhesion, preventing seeds from accumulating in the gap between the seed metering wheel 10 and the chamber wall, avoiding jamming of the seed metering wheel 10 or blockage of the feeding chamber due to accumulation. The shape of each feeding chamber on the descending side of the sowing groove 14, adapted to the size of the seed metering wheel 10, also prevents seeds from falling during the feeding process. The brush 11 is located on the side wall of the sowing groove 14 in the rising state, and the shape of the side wall of each feeding chamber on the side of the sowing groove 14 in the falling state is adapted to the size of the seed metering wheel 10. The frame is detachably connected to the power unit or tractor through the connecting frame 13.

[0023] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
