Description

Technical Field

[0001] This utility model relates to the field of agricultural sowing machinery, and in particular to a single-row, double-row peanut sowing device. Background Technology

[0002] When planting peanuts, the planting depth is a key factor affecting emergence rate and yield, therefore, strict requirements are placed on the qualification rate and consistency of planting depth. Generally, the agronomical requirement for spring-sown peanuts is to control the planting depth at 3-5 cm, with an error of no more than ±1 cm. In actual production, appropriate adjustments are made based on factors such as region, soil type, soil moisture, peanut variety, and planting season. Existing single-ridge double-row peanut planters using mechanical contour-following mechanisms for planting depth adjustment have inherent defects: when the ridge surface is uneven or the furrow depth is inconsistent, the planting depth of the two rows will interfere with each other, resulting in one row's furrow opener being over-penetrated while the other row is under-penetrated or even suspended, causing a decrease in planting depth consistency or even unqualified planting depth; the contour-following mechanism is easily trapped by the soil when in contact with the ridge surface, leading to reduced effectiveness or even malfunction; once stuck, it not only fails to achieve the adjustment effect but also easily damages the ridge surface; in environments with low ridge surface flatness, the contour-following and adjustment accuracy is low, resulting in a large difference in actual planting depth and low planting depth consistency; the standard planting depth is fixed and cannot be adjusted, resulting in poor adaptability. Utility Model Content

[0003] The technical problem to be solved by this utility model is: how to provide a single-ridge double-row peanut planting device to improve the qualified rate, consistency and adaptability of planting depth.

The adjustment assemblies are disposed at the bottom of the frame, and the two sets of adjustment assemblies are electrically connected to the controller. Each adjustment assembly has a detection component, an execution component, a planter, and a connector.

[0005] Furthermore, the detection component and the execution component are electrically connected to the controller, which is located between the two sets of adjustment combinations. Furthermore, the lower end of the detection component is higher than the lower end of the seeder.

[0006] Furthermore, the detection component and the seeder are arranged sequentially backward along the forward direction of the frame.

[0007] Furthermore, the frame has guide posts that are locked to both sides of the frame, and the connector has a sleeve that can slide on the guide posts.

[0013] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0014] Please refer to Figures 1 to 4 A single-row, double-row peanut planting device includes: a frame 1, a controller 2, and two sets of adjustment assemblies 3. The adjustment assemblies 3 are located at the bottom of the frame 1, and the two sets of adjustment assemblies 3 are electrically connected to the controller 2 respectively. The adjustment assembly 3 has a detection component 32, an execution component 33, a planter 34, and a connector 31. The detection component 32, the execution component 33, and the planter 34 are all fixedly connected to the connector 31. The connector 31 is slidably connected to the frame 1.

[0015] As can be seen from the above description, the beneficial effects of this utility model are as follows: By setting two sets of independent adjustment combinations 3 at the bottom of the frame 1, which are electrically connected to the controller 2 respectively, and the detection component 32, execution component 33, and seeder 34 in each adjustment combination 3 are integrated and fixed through connector 31 and slidably connected to the frame 1, on the one hand, independent and precise control of the double row sowing depth can be achieved, effectively avoiding the problem of mutual interference between the two rows of depth caused by uneven ridge surface and inconsistent furrow depth in traditional linkage adjustment, ensuring that the sowing depth of each row conforms to agronomic requirements, and improving the consistency and qualification rate of sowing depth; on the other hand, the independent adjustment design can also flexibly set the two rows of sowing depth according to different needs such as region, soil quality, and soil moisture, breaking through the scenario limitations of traditional fixed depth equipment and enhancing the adaptability to complex planting environments.

[0016] Furthermore, the detection component 32 and the execution component 33 are electrically connected to the controller 2, which is located between the two sets of adjustment combinations 3.

[0017] As described above, the controller 2 is positioned in the middle of the two sets of adjustment combinations 3, which can shorten the electrical connection line length between the controller 2 and the detection components 32 and execution components 33 on both sides, reduce interference and delay in the signal transmission process, improve the control response speed, and at the same time make the overall circuit layout more regular, reduce the difficulty of equipment assembly and later maintenance, and further ensure that the two sets of adjustment combinations 3 can independently and efficiently complete their respective seeding depth control tasks.

[0018] Furthermore, the lower end of the detection component 32 is higher than the lower end of the seeder 34.

[0019] As described above, the lower end of the detection component 32 is higher than the lower end of the seeder 34. This design can prevent the detection component 32 from directly contacting the soil during operation: on the one hand, it can prevent the detection component 32 from physical wear and tear due to friction and impact with the soil, effectively reducing the risk of component damage and extending its service life; on the other hand, it can prevent the detection component 32 from squeezing or scraping the ridge surface when it comes into contact with the soil, thereby protecting the original structural integrity of the ridge surface and providing a guarantee for the standardized implementation of subsequent sowing operations.

[0020] Furthermore, the detection component 32 and the seeder 34 are arranged sequentially backward along the forward direction of the frame 1.

[0021] As described above, when the frame 1 moves forward, the detection component 32 at the front can prioritize sensing the current height of the ridge surface and obtain the distance data between the ridge surface and the ridge surface in real time. Then, the seeder 34 at the rear can complete the furrowing and seeding actions based on this real-time detection result, avoiding data lag caused by spatial misalignment between detection and seeding, and ensuring that the detection data can accurately match the actual situation of the ridge surface at the location of the seeder 34.

[0022] Furthermore, the frame 1 has guide posts 11, which are locked to both sides of the frame 1, and the connector 31 has a sleeve 311, which can slide on the guide posts 11.

[0023] As described above, the cooperation between the guide post 11 and the sleeve 311 provides precise guiding constraints for the movement of the connector 31, ensuring that the connector 31 drives the integrated component to move smoothly only in the vertical direction, avoiding deviation or shaking of the component during lifting and lowering, ensuring the linearity and accuracy of the seeder 34's soil penetration depth adjustment, and thus improving the precision of seeding depth control. On the other hand, the locked and fixed guide post 11 has a stable structure and can withstand the force when the component moves, reducing frictional wear between parts. At the same time, the sleeve 311 slides smoothly and reliably along the guide post 11, reducing the risk of jamming when the component is lifted and lowered, and ensuring timely response of the adjustment action.

[0024] Furthermore, the actuator 33 can extend and retract vertically, thereby causing the connector 31 to move vertically.

[0025] As described above, the telescopic function of the actuator 33 can flexibly control the lifting and lowering amplitude in conjunction with the instructions of the controller 2. It can quickly adjust the sowing depth according to the difference in ridge height fed back by the detection component 32, and can stably maintain a qualified sowing depth. At the same time, combined with the sliding guide structure of the connector 31 and the frame 1, it can further ensure the stability of the actuator 33 when driving the components to lift and lower.

[0026] Furthermore, the seeder 34 includes a furrow opener 341, a seed drop tube 342, and a soil coverer 343; the furrow opener 341 and the seed drop tube 342 are fixed to the connector 31 by the same bolts, and the furrow opener 341 is bolted to the soil coverer 343.

[0027] As described above, the furrow opener 341 and the seeding tube 342 share the same bolt and are fixed to the connector 31, which ensures that the two remain in a fixed relative position when they are raised and lowered with the connector 31, and avoids deviation between the furrow opening position and the seeding position due to loose connection. The furrow opener 341 and the covering device 343 are connected by bolts, which makes it easy to adjust the angle or height of the covering device 343 according to different soil types and moisture conditions, and improve the adaptability of the covering effect.

[0028] Please refer to Figures 1 to 4 The first embodiment of this utility model is as follows: a single-ridge double-row peanut planting device, including: a frame 1, a controller 2, and two sets of adjustment assemblies 3. The adjustment assemblies 3 are set at the bottom of the frame 1, and the two sets of adjustment assemblies 3 are electrically connected to the controller 2 respectively. The adjustment assembly 3 has a detection component 32, an execution component 33, a planter 34 and a connector 31. The detection component 32, the execution component 33 and the planter 34 are all fixedly connected to the connector 31. The connector 31 is slidably connected to the frame 1.

[0029] In this embodiment, guide posts 11 are locked to both sides of the frame 1. The connector 31 is equipped with a sleeve 311 that can slide along the guide posts 11, and the actuator 33 can extend and retract vertically, driving the connector 31 to move up and down synchronously. The detection component 32 and the actuator 33 are electrically connected to the controller 2, which is located between the two sets of adjustment combinations 3. The detection component 32 and the seeder 34 are arranged sequentially backward along the forward direction of the frame 1, and the lower end of the detection component 32 is higher than the lower end of the seeder 34. The detection component 32 is a non-contact distance detection device, such as an ultrasonic rangefinder or a laser rangefinder. The actuator 33 is a telescopic device, such as an electric cylinder or an electric push rod. By using two sets of combinations consisting of the detection component 32, the actuator 33, the seeder 34, and the connector 31 to independently adjust the planting depth of two rows of peanuts, the problem of mutual interference can be solved, and the flexibility and accuracy of adjustment can be improved. By using the controller 2 for monitoring and adjustment, the automatic adjustment of the planting depth can be realized, and only one controller 2 is used to simultaneously adjust the planting depth of two rows of peanuts, which has the advantage of compact structure. The seeder 34 includes a furrow opener 341, a seed drop tube 342, and a soil coverer 343. The furrow opener 341 and the seed drop tube 342 are fixed to the connector 31 by the same bolt, while the furrow opener 341 and the soil coverer 343 are connected by bolts separately.

[0030] In this embodiment, during operation, a standard sowing depth value is set on the controller 2 according to agronomic requirements. The sowing process detection component 32 detects the distance from its bottom to the ridge surface in real time. The controller 2 collects the distance data of each group of detection components 32 in real time and compares it with the preset standard sowing depth value. If the sowing depth of the group is not qualified, the execution component 33 of the group is controlled to extend and retract. The execution component 33 drives the detection component 32 and the seeder 34 to move vertically up and down together through the connector 31. During the movement, the soil penetration depth of the seeder 34 changes to adjust the sowing depth. Since the detection components 32 move together, the change in sowing depth is consistent with the change in the distance data of the detection components 32. When the sowing depth of the group is qualified, the execution component 33 of the group stops extending and retracting. When the sowing depth is not qualified again, the adjustment is automatically performed in this way. Moreover, the adjustment of each group is carried out independently and does not affect each other.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
