Description

Technical Field

[0001] This utility model belongs to the field of sowing equipment technology, specifically relating to a millet and peanut strip intercropping sowing machine. Background Technology

[0002] The millet-peanut strip intercropping seeder is mainly used to achieve strip intercropping of millet and peanuts. Its seeding mechanism is driven by a tractor or other power machinery to provide the power required for the seeder's movement and component operation, realizing seeding operations along the planting area. Therefore, although the millet-peanut strip intercropping seeder improves planting efficiency, when millet and peanuts are sown simultaneously, the throughput of the continuous seeding operation mode is uncertain, which may lead to uneven seed distribution. Although the existing technology controls the seeding quantity by controlling the electronic seeding valve, after the seeding box is reduced to the bottom position, the empty space inside the seeding box increases, and the throughput of seeds when output by the electronic seeding valve will be significantly reduced. Utility Model Content

[0003] This invention provides a millet and peanut strip intercropping planter to solve the problems mentioned in the background art.

[0004] This utility model provides the following technical solution: a millet and peanut strip intercropping seeder, comprising several seed storage hoppers and a drive assembly. A mounting bracket is provided on the top of each seed storage hopper, and a top frame is fixedly connected to the mounting bracket. A lifting plate is fixedly connected to one end of the top frame, and a blocking block is fixedly connected to the bottom of the lifting plate. The blocking block is slidably connected to the seed storage hopper. A small-volume seed conveying seat is fixedly connected to one end of the seed storage hopper near the blocking block. A drive motor is installed at one end of the small-volume seed conveying seat, and the drive motor housing is fixedly connected to the small-volume seed conveying seat. The output end of the drive motor extends to the inside of the small-volume seed conveying seat. An output through-surface compression assembly is installed on the small-volume seed conveying seat. The output through-surface compression assembly includes a connecting crossbar, a sliding lifting rod, and a trapezoidal compression plate. The connecting crossbar is fixedly connected to the sliding lifting rod, which is slidably connected to the small-volume seed conveying seat. The trapezoidal compression plate is fixedly connected to the connecting crossbar.

[0005] The actuation drive assembly includes a front frame, a fixed bracket, a rotating disc, and a drive motor. The housing of the drive motor is fixedly connected to the front frame via the fixed bracket. The output end of the drive motor passes through the rotating disc and is fixedly connected to the top frame. The front frame is fixedly connected to the rotating disc.

[0006] The small seed delivery seat has a seed outlet at one end, and the output end of the drive motor is fixedly connected to several seeding plates arranged in a ring.

[0007] The small-volume seed delivery seat has a directional groove, the sliding lifting rod is slidably connected to the directional groove, and a tension spring is fixedly connected between the sliding lifting rod and the inner wall of the directional groove.

[0008] The mounting bracket is fixedly connected to the rotating disc.

[0009] The seed storage hopper has a temporary seed storage port at one end near the small seed delivery seat, and one end of the sealing block is slidably connected to one side of the temporary seed storage port.

[0010] The beneficial effects of this utility model are:

[0011] 1. Before sowing, millet and peanut seeds are temporarily stored in the seed storage hopper. During sowing, the drive motor is intermittently controlled to rotate and tilt the seed storage hopper counterclockwise. When the seed storage hopper tilts briefly, the blocking block and the temporary seed inlet are in a conductive state, allowing some seeds to enter the small seed inlet and then enter the inner side of the small seed inlet. After the drive motor reaches the set driving time, the drive motor controls the seed storage hopper to reset, blocking the temporary seed inlet and the small seed inlet. This achieves the purpose of controlling the number of seeds stored in the small seed inlet, ensuring that a single sowing action does not exceed the amount stored in the small seed inlet, avoiding uneven distribution of input caused by continuous seeding operations, and improving sowing accuracy.

[0012] 2. After seeds are filled into the inner side of the small-quantity seed delivery seat, the drive motor drives the sowing plate to push the seeds out through the seed outlet into the soil. Through the design of the trapezoidal compression plate, connecting crossbar, and sliding lifting rod, the trapezoidal compression plate continuously reduces the internal space of the small-quantity seed delivery seat during the sowing process. Only when the front end of the sowing plate rotates to the contact surface with the trapezoidal compression plate does the trapezoidal compression plate experience force and be longitudinally lifted through the sliding engagement of the sliding lifting rod with the small-quantity seed delivery seat. This prevents the seeds from being directly squeezed by the trapezoidal compression plate as they pass through it during the sowing process. This avoids affecting seed passage due to the large empty space inside the small-quantity seed delivery seat when the number of seeds decreases, and effectively reduces excessive seed compression damage, ensuring the quality of the seeds after delivery.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0019] Please see Figures 1-4 This utility model provides the following technical solution: a millet and peanut strip intercropping seeder, comprising a seed storage hopper 1 and a toggle drive assembly 4. A mounting bracket 2 is provided on the top of the seed storage hopper 1, and a top frame 3 is fixedly connected to the mounting bracket 2. A lifting plate 31 is fixedly connected to one end of the top frame 3, and a sealing block 32 is fixedly connected to the bottom of the lifting plate 31. The sealing block 32 is slidably connected to the seed storage hopper 1. A small seed conveying seat 5 is fixedly connected to one end of the seed storage hopper 1 near the sealing block 32. A small seed conveying seat 5 is mounted on one end of the seed storage hopper 1. The device is equipped with a drive motor 51, the housing of which is fixedly connected to the small-volume seed delivery base 5. The output end of the drive motor 51 extends to the inside of the small-volume seed delivery base 5. The small-volume seed delivery base 5 is equipped with an output through-surface compression assembly 6, which includes a connecting crossbar 61, a sliding lifting rod 62, and a trapezoidal compression plate 63. The connecting crossbar 61 is fixedly connected to the sliding lifting rod 62, the sliding lifting rod 62 is slidably connected to the small-volume seed delivery base 5, and the trapezoidal compression plate 63 is fixedly connected to the connecting crossbar 61.

[0020] The toggle drive assembly 4 includes a front frame 41, a fixed bracket 42, a rotating disc 43, and a drive motor 44. The housing of the drive motor 44 is fixedly connected to the front frame 41 through the fixed bracket 42. The output end of the drive motor 44 passes through the rotating disc 43 and is fixedly connected to the top frame 3. The front frame 41 is fixedly connected to the rotating disc 43.

[0021] In this embodiment, the front frame 41 is connected to the external drive equipment frame to realize transportation during sowing. Since this part is not an improvement of this utility model, its transportation drive principle will not be described in detail here. Before sowing begins, the millet and peanut seeds are temporarily stored in the seed storage hopper 1. During the sowing operation, the drive motor 44 is intermittently controlled to drive the seed storage hopper 1 to rotate and tilt counterclockwise. When the seed storage hopper 1 is tilted briefly, the blocking block 32 and the temporary seed delivery port 11 are in a conductive state, so that some seeds enter the inner side of the small seed delivery seat 5 through the temporary seed delivery port 11. After the drive motor 44 reaches the driving time set, the drive motor 44 controls the seed storage hopper 1 to reset, so that the temporary seed delivery port 11 and the small seed delivery seat 5 are blocked, thereby controlling the number of seeds stored in the small seed delivery seat 5. This ensures that a single sowing action will not exceed the storage capacity inside the small seed delivery seat 5, avoiding uneven distribution of input caused by continuous seeding operation and improving sowing accuracy.

[0022] In this embodiment, the present invention provides a preferred arrangement for storing seeds in the seed storage hopper 1, which ensures that the arrangement position can stably achieve side-row sowing of millet when millet and peanuts are sown simultaneously. Please refer to the accompanying drawings in the specification. Figure 2 When eight seed storage hoppers are set up horizontally, the arrangement of the seeds stored in the eight seed storage hoppers 1 from left to right is as follows: two hoppers for millet, four hoppers for peanuts, and two hoppers for millet. This arrangement ensures that the millet is always in a marginal position during sowing, thus guaranteeing the marginal advantage of millet.

[0023] One end of the small seed delivery seat 5 is provided with a seed delivery port 52, and the output end of the drive motor 51 is fixedly connected to several seeding plates 53 arranged in a ring.

[0024] Mounting bracket 2 is fixedly connected to rotating disc 43.

[0025] The seed storage hopper 1 has a temporary seed delivery port 11 at one end near the small seed delivery seat 5, and one end of the sealing block 32 is slidably connected to one side of the temporary seed delivery port 11.

[0026] The small-volume seed delivery seat 5 has a directional slide groove 501, and a sliding lifting rod 62 is slidably connected to the directional slide groove 501. A tension spring 621 is fixedly connected between the sliding lifting rod 62 and the inner wall of the directional slide groove 501.

[0027] After seeds are filled into the inner side of the small-volume seed delivery seat 5, the drive motor 51 drives the sowing plate 53 to push the seeds out through the seed outlet 52 into the soil. Through the arrangement of the trapezoidal compression plate 63, the connecting crossbar 61, and the sliding lifting rod 62, the trapezoidal compression plate 63 maintains a reduction in the internal space of the small-volume seed delivery seat 5 during the sowing process. Only when the front end of the sowing plate 53 rotates to the contact surface with the trapezoidal compression plate 63 does the trapezoidal compression plate 63 experience force and slide against the small-volume seed delivery seat 5 through the sliding lifting rod 62. The longitudinal section is raised until the trapezoidal compression plate 63 is no longer in contact with the sowing plate 53. Then, the tension spring 621 inside the directional chute 501 contracts, causing the trapezoidal compression plate 63 to sink and reset. This prevents the seeds from being directly squeezed by the trapezoidal compression plate 63 when they pass through the position of the trapezoidal compression plate 63 during the process of being moved by the sowing plate 53. This avoids the seed delivery passage being affected by the large empty space inside the small seed delivery seat 5 when the number of seeds in the small seed delivery seat 5 decreases. At the same time, it can effectively reduce the damage caused by excessive compression of seeds and ensure the quality of seeds after delivery.

[0028] The working principle of this utility model is as follows: Before sowing, millet and peanut seeds are temporarily stored in the seed storage hopper 1. During sowing, the drive motor 44 is periodically controlled to drive the seed storage hopper 1 to rotate counterclockwise and tilt, so that the sealing block 32 and the temporary seed delivery port 11 are in a conductive state. A portion of the seeds inside the seed storage hopper 1 enters the inner side of the small seed delivery seat 5 through the temporary seed delivery port 11. After the required sowing time is reached, the drive motor 44 controls the seed storage hopper 1 to reset, so that the temporary seed delivery port 11 and the small seed delivery seat 5 are blocked. Then, the drive motor 51 drives the sowing plate 53 to push the seeds out through the seed delivery port 52 into the soil. The sowing plate 53 rotates during the sowing process. In this process, the trapezoidal compression plate 63 always reduces the internal space of the small seed delivery seat 5. Only when the front end of the sowing plate 53 rotates to the contact surface with the trapezoidal compression plate 63, the trapezoidal compression plate 63 is subjected to force and longitudinally lifted through the sliding engagement of the sliding lifting rod 62 with the small seed delivery seat 5. This prevents the seeds from being directly squeezed by the trapezoidal compression plate 63 when they pass through the position of the trapezoidal compression plate 63 during the process of being propelled by the sowing plate 53. This avoids the seed delivery passage being affected by the large empty space inside the small seed delivery seat 5 when the number of seeds in the small seed delivery seat 5 decreases. At the same time, it can effectively reduce the damage caused by excessive compression of seeds and ensure the quality of seeds after delivery.
