Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting equipment technology, specifically a peanut planting device. Background Technology

[0002] Its main function is to evenly sow seeds into the soil to improve planting efficiency and survival rate. However, existing seeders have many shortcomings in practical use: During the discharge process, the seeds fall rapidly and lack an effective buffer mechanism, resulting in violent collisions between the seeds and the discharge pipe and plow head. This can easily cause seed damage and reduce the germination rate. This problem is particularly prominent for seeds with smaller grains or brittle shells, which increases planting costs. The existing seeders have poor directional seeding performance. Seeds are prone to deviation during sowing and cannot be accurately placed in the designated planting position. This requires manual adjustment afterward, which increases labor intensity and also affects the uniformity of planting and the efficiency of subsequent field management. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a peanut planting device with the advantages of flexible adjustment of planting spacing, effective buffering and protection of seeds, and good directional placement effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a peanut planting device, comprising a planter and a discharge device mounted on the planter, wherein the discharge device comprises a discharge pipe, a plow head, an adjustable spacing device, a buffer device, and a directional delivery device; The adjustable spacing device is installed inside the discharge pipe and is used to adjust the spacing inside the discharge pipe. The adjustable spacing device includes a solid cylinder, which is located inside the discharge pipe. Several sets of baffles are arranged around the bottom of the solid cylinder for fixing by hinges. Several baffles are arranged in a circle at the bottom of the solid cylinder. Locking rods are threadedly connected to the surfaces of the discharge pipe and the baffles. The locking rods are used to push the baffles to tilt towards the center position.

[0005] Preferably, the buffer device is located inside the discharge pipe and at the bottom of the baffle to buffer the falling seeds. The buffer device includes an arc-shaped seat, an elastic pad, a sponge, and vent holes. The arc-shaped seat is welded and fixed to the inner wall of the discharge pipe. The feed end of the arc-shaped seat is arc-shaped. The elastic pad is made of rubber and is fixed to the inner side of the arc-shaped seat by corrugated pipe. The sponge fills the space between the arc-shaped seat and the elastic pad. The vent holes are opened on the arc-shaped seat and communicate with the sponge. There are multiple vent holes, which are evenly distributed on the arc-shaped seat.

[0006] Preferably, the directional dispensing device is located at the lower end of the discharge pipe to achieve directional dispensing of seeds. The directional dispensing device includes a clamping seat and a brush. The clamping seat is fixedly connected to the discharge pipe by bolts. The brush is made of nylon material and is glued to the bottom end of the clamping seat 251 and tilted towards the center.

[0007] Preferably, the angle between the baffle and the solid cylinder is between 0° and 15°, and the baffle is made of a smooth and wear-resistant material.

[0008] Preferably, the adjustable spacing device, the buffer device, and the directional dispensing device are all parallel to the discharge pipe.

[0009] Preferably, the solid cylinder and the arc-shaped seat are both connected to the discharge pipe by bolt fixing.

[0010] Preferably, several sets of discharge pipes are connected to the feed end of the plow, and the discharge pipes are configured with different curvatures.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adds an adjustable spacing device and a directional feeding device inside the discharge pipe, and adds a baffle with manually adjustable discharge gap at the bottom of the solid cylinder. This allows seeds of different particle sizes to be discharged from the bottom of the baffle and guide the seeds to flow towards the center, avoiding contact between the seeds and the inner wall of the discharge pipe, which would cause the seeds to shake inside the discharge pipe. The elastic pad and sponge on the curved seat surface cushion the seeds. The sponge surface has venting grooves; when the sponge is compressed, gas is released into the discharge pipe through the venting holes. At the same time, the honeycomb holes disrupt the vortex airflow within the channel, reducing airflow interference with the seed trajectory. A brush is added to the bottom of the clamping seat. The tips of the brush converge inward to form a flexible channel with a diameter slightly larger than the seed size. When the seed passes through the brush, the flexible contact of the brush can further attenuate the kinetic energy and guide the seed to the center, ensuring that it falls along the central axis of the channel and reducing the deviation at the exit.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 5 As shown, this utility model provides a peanut planting device, including a planter 1 and a discharge device 2 installed on the planter 1. The discharge device 2 includes a discharge pipe 21, a plow head 22, an adjustable spacing device 23, a buffer device 24, and a directional delivery device 25. An adjustable spacing device 23 is installed inside the discharge pipe 21 to adjust the spacing inside the discharge pipe 21. The adjustable spacing device 23 includes a solid cylinder 231, which is located inside the discharge pipe 21. Several sets of baffles 233 are arranged around the bottom of the solid cylinder 231 for fixing by hinges. The baffles 233 are arranged in a circle at the bottom of the solid cylinder 231. A locking rod 232 is threadedly connected to the surface of the discharge pipe 21 and the baffles 233. The locking rod 232 is used to push the baffles 233 to tilt towards the center position and change the direction of seed falling, so that it slides along the surface of the baffles 233 to the middle section of the channel, avoiding direct impact on the inner wall of the channel.

[0016] Specifically, the buffer device 24 is installed inside the discharge pipe 21 and located at the bottom end of the baffle 233 to buffer the falling seeds. The buffer device 24 includes an arc-shaped seat 241, an elastic pad 242, a sponge 243, and a vent 244. The arc-shaped seat 241 is welded and fixed to the inner wall of the discharge pipe 21. The inlet end of the arc-shaped seat 241 is arc-shaped. The elastic pad 242 is made of rubber and is fixed to the inner side of the arc-shaped seat 241 by corrugated pipe. It can be buffered by slight compression. The force is transferred to the surface of the elastic pad 242. When the surface of the elastic pad 242 is compressed, it will compress the sponge 243. The sponge 243 is forced to expel air outward. The exhaust holes 244 are opened on the arc-shaped seat 241 and are connected to the sponge 243. There are multiple exhaust holes 244, which are evenly distributed on the arc-shaped seat 241. When the seed slides over the arc segment, some of the kinetic energy is transferred and released by compressing the sponge 243. At the same time, the honeycomb holes can disrupt the vortex airflow in the channel and reduce the interference of airflow on the seed trajectory.

[0017] Furthermore, a directional dispensing device 25 is installed at the lower end of the discharge pipe 21 to achieve directional dispensing of seeds. The directional dispensing device 25 includes a clamping seat 251 and a brush 252. The clamping seat 251 is fixedly connected to the discharge pipe 21 by bolts. The brush 252 is made of nylon material and is glued to the bottom end of the clamping seat 251 and tilted towards the center. The tips of the brush 252 converge inward to form a flexible channel with a diameter slightly larger than the seed particle size. When the seed passes through the brush 252, the flexible contact of the brush 252 can further attenuate the kinetic energy and guide the seed in a centered position to ensure that it falls along the central axis of the channel and reduce the deviation at the outlet.

[0018] Furthermore, the angle between the baffle 233 and the solid cylinder 231 is between 0° and 15°, which can guide seeds of different sizes. The baffle 233 is made of smooth and wear-resistant material, which further enhances the anti-sticking property and ensures that the seeds fall smoothly even in a humid environment, reducing seed adhesion and frictional resistance and ensuring smooth falling.

[0019] It is worth noting that the adjustable spacing device 23, the buffer device 24, and the directional dispensing device 25 are all parallel to the discharge pipe 21.

[0020] It is worth noting that the solid cylinder 231 and the arc-shaped seat 241 are both connected to the discharge pipe 21 by bolts, which can facilitate timely replacement in case of damage.

[0021] It is worth mentioning that several sets of discharge pipes 21 are connected to the feed end of the plow head 22, and the discharge pipes 21 are set with different curvatures.

[0022] Among them, the seeder 1 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0023] Working principle: Before sowing, adjust the gap between several sets of baffles 233 according to the size of the crop seeds to ensure that the seeds can flow through the inside of the baffles 233. Specifically, turn the locking rod 232 clockwise. The locking rod 232 passes through the inside of the discharge pipe 21 and squeezes the baffles 233 to shift towards the center position. The bottom position of the baffle 233 is smaller than the top position, which can ensure that the seeds flow downward from the center position of the discharge pipe 21. Conversely, when the seeds are large, the locking rod 232 needs to be turned counterclockwise. The locking rod 232 expands outward and fits against the inner wall of the discharge pipe 21 to the maximum extent. The bottom discharge end is flush with the feed end. When the seeder 1 is started, the seeds enter the discharge pipe 21 from the feed box of the seeder body 1. As the seeds fall in the discharge pipe 21, they pass through the solid cylinder 231 and are gathered towards the center by the baffle 233. Then they fall downwards and come into contact with the arc-shaped seat 241 and the arc-shaped elastic pad 242. The elastic pad 242 deforms and squeezes the sponge 243. The air in the sponge 243 is discharged through the exhaust hole 244. The elastic pad 242 and the sponge 243 absorb the impact force of the seeds and reduce the falling speed of the seeds. After the sponge 243 is squeezed, some of the kinetic energy is transferred and released through the squeezing of the sponge 243. At the same time, the honeycomb holes can disrupt the vortex airflow in the channel and reduce the interference of the airflow on the seed trajectory. After being buffered, the seeds are discharged from the outlet of the discharge pipe 21 and, guided by the symmetrically arranged brushes 252, are accurately placed into the seed furrows opened by the plow head 22, thus completing the sowing operation.
