Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a corn two-row three-row staggered sowing aid. Background Technology

[0002] Corn is an important food crop in my country. Improving yield per unit area, optimizing planting structure, and enhancing resource utilization are the core goals of the current development of the corn industry. Reasonable close planting is one of the key measures to increase corn yield per unit area.

[0003] Two-row, three-row planting of corn is a high-efficiency cultivation model aimed at optimizing field resource allocation and increasing yield per unit area. Traditional equal-row planting model, under dense planting conditions, often leads to poor ventilation and light conditions, aggravated pests and diseases, and increased risk of lodging due to excessively close plant spacing, thus limiting further improvement in yield and quality.

[0004] Some existing corn planters, especially those designed for the two-row, three-row planting pattern, typically have a fixed planting position in the direction of travel, resulting in multiple rows of plants being arranged in a straight line. This can easily lead to canopy closure in the field, severely affecting ventilation and light exposure in the lower part of the plant, limiting the improvement of light energy utilization efficiency and yield potential. Furthermore, the height of the furrowing and backfilling components is mostly manually adjustable as a whole, which is cumbersome and has low applicability, failing to meet the needs of modern agriculture for precise, efficient, and highly adaptable planting operations.

[0005] Therefore, those skilled in the art provide a corn two-row three-row staggered planting aid to solve the problems mentioned in the background art above. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-6 As shown, this utility model provides a technical solution: a corn two-row three-row staggered planting assistant, including a vehicle body component 1. Several support components 3 are arranged on the left and right sides of the upper end of the vehicle body component 1. Planting components 4 are installed on the inner surface of the several support components 3. The rear ends of the several support components 3 are fixedly installed with a front and rear adjustment component 5. A handle 2 is fixedly installed in the middle of the rear end of the front and rear adjustment component 5. Auxiliary components 6 are fixedly installed on the left, right and middle sides of the bottom of the front and rear adjustment component 5. A trenching component 7 is arranged on the front side of the bottom of the vehicle body component 1. A soil filling component 8 is arranged on the rear side of the bottom of the vehicle body component 1. A height adjustment component 9 is fixedly installed in the middle of the bottom of the trenching component 7 and the soil filling component 8. The lower side of the outer surface of the two height adjustment components 9 is fixedly installed on the front and rear sides inside the vehicle body component 1, respectively.

[0027] As one implementation method in this embodiment, please refer to Figure 1 and Figure 5 As shown, the vehicle body assembly 1 includes a frame 11, a bearing support 12 is fixedly connected to the front side of the top of the frame 11, a front wheel 13 is rotatably connected to the inner surface of the bearing support 12, and an auxiliary rear wheel 14 is fixedly connected to the middle of the rear end of the frame 11.

[0028] The vehicle body assembly 1 serves as the load-bearing and moving base for the entire device, and its main body is the vehicle frame 11.

[0029] The front wheel 13 and the auxiliary rear wheel 14 together form a stable inverted triangle support layout;

[0030] Among them, the front wheel 13 has a dual-wheel structure, the auxiliary rear wheel 14 has a single-wheel structure, and the diameter of the auxiliary rear wheel 14 is smaller than the diameter of the front wheel 13;

[0031] Specifically, the two wheels of the front wheel 13 are rotatably connected to the bearing support 12 fixed at the front of the frame 11 via a support shaft (not shown in the figure). Similarly, the single wheel of the auxiliary rear wheel 14 is also rotatably connected to the rear of the frame 11 via a corresponding shaft and bearing structure.

[0032] The wheel system is designed to adapt to the two-row, three-ridge sowing pattern. During operation, the two wheels of the front wheel 13 roll along the outside of the two furrows in the target sowing area, providing main support and guidance, while the smaller diameter auxiliary rear wheel 14 travels on the ridge between the two furrows, playing a role in stabilization, balance and auxiliary support, ensuring that the vehicle moves smoothly.

[0033] The operator can drive the entire vehicle assembly 1 to move along the ridge direction to carry out the sowing operation by pushing or pulling the hand handle 2;

[0034] When in the sowing operation state, the front and rear wheels of the vehicle body component 1 are in contact with the ground under the action of its own weight and the downward pressure applied by the operator, so that the trenching component 7 and the soil filling component 8 at the rear end can cut into the soil at a preset height to work. When the transfer device is needed or in the non-operation state, the operator only needs to pull the handle 2 upward, and use the support pivot at the front end of the frame 11 as the fulcrum to make the rear end of the vehicle body tilt upward, and the auxiliary rear wheel 14 will lift off the ground.

[0035] At this point, the trenching component 7 and the filling component 8, among other working parts, are completely lifted off the ground, with only the front wheel 13 touching the ground, which greatly reduces the resistance to movement and enables convenient transportation and parking of the device.

[0036] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 As shown, several support components 3 each include a support frame 31, and a base plate 32 is fixedly connected to one side of the inner surface of the support frame 31. A drive box 33 is fixedly connected to the top of the base plate 32. Several seeding components 4 each include a seed metering device 41. The center of the seed metering device 41 is installed at the output end of the drive box 33. A feed hopper 42 is fixedly connected to the middle of the top of the seed metering device 41. A collection box 43 is fixedly connected to the top of the feed hopper 42. A top cover 44 is snapped onto the top of the collection box 43.

[0037] The front sides of the outer surfaces of several top covers 44 are fixedly connected to the front ends of several support frames 31 respectively. The front ends of the support frames 31 are provided with support brackets (not shown in the figure) that can reach the height of the top covers 44.

[0038] Each drive box 33 includes a mounting box, drive motor, and motor controller as in the prior art. The controller is used to control the opening, closing, and rotation speed of the motor and is linked with the overall control system of the device to activate the transmission components at the appropriate time.

[0039] The seed metering device 41 in this solution can be a rotary seed metering device in the prior art, which includes a fixed outer shell and a seed metering disc.

[0040] The controller precisely adjusts the motor speed according to the forward speed of the unit, driving the seed metering disc with the shaped hole at the seed metering device 41 to rotate inside the seed metering device 41 and at the bottom of the collection box 43. When the shaped hole passes through the seed filling area, the seeds are captured one by one under the action of gravity, completing the quantitative seed collection.

[0041] The seeds are transported to the seed inlet of the seed metering device 41 under the protection of the seed protection plate, and fall precisely into the seed guide tube due to the loss of support. The seeds at the seeding component 4 can be placed into the collection box 43 by opening the top cover 44. The structure at the seeding component 4 is supported and driven by the support component 3 on the same side.

[0042] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4 As shown, the front and rear adjustment assembly 5 includes several mounting plates 51, which are fixedly connected to the rear ends of several support frames 31. Each of the mounting plates 51 has an electric push rod 52 fixedly installed at its rear end. The rear ends of the electric push rods 52 are all connected to a main control box 53. The bottom of the main control box 53 is symmetrically connected to connecting brackets 54. The bottoms of the two connecting brackets 54 are fixedly connected to the left and right sides of the rear top of the frame 11, respectively.

[0043] Several auxiliary components 6 include slide rail seats 61. The rear side of the top of several slide rail seats 61 is fixedly connected to the left, right and middle sides of the bottom of the main control box 53, respectively. Sliding brackets 62 are slidably connected to the inner surface of the slide rail seats 61. The top of several sliding brackets 62 is fixedly connected to the rear side of the bottom of several support frames 31, respectively.

[0044] The cylinder end of the electric push rod 52 is fixedly installed on the fixed base outside the main control box 53 by means of hinge or bolt connection, and the front end of its telescopic rod is rigidly connected to the base of the support assembly 3 through the mounting plate 51.

[0045] Therefore, the telescopic movement of the electric push rod 52 can directly drive the support assembly 3 and the seeding assembly 4 on it to move linearly along the direction of the unit's travel, i.e., the front-to-back direction.

[0046] To achieve staggered sowing, this embodiment sets up multiple (e.g., three) independent electric push rods 52, which respectively drive three independent support components 3 and sowing components 4. The controller inside the main control box 53 (not shown in the figure) can independently control the extension and retraction stroke of each electric push rod 52, thereby making differentiated adjustments to the longitudinal position of each sowing component 4, so that the three form a preset staggered layout.

[0047] During sowing, the three sowing components 4, after adjustment, are no longer in a straight line in the direction of travel, but are staggered. This layout makes the corn plants after sowing also staggered in the field, thereby optimizing the canopy structure of the population, improving ventilation and light conditions between plants, increasing light energy utilization efficiency, and ultimately achieving the goal of increasing yield.

[0048] As the electric push rod 52 extends and retracts, the sliding bracket 62 slides in conjunction with the electric push rod 52 and the slide rail seat 61, thereby providing support for the support component 3.

[0049] As one implementation method in this embodiment, please refer to Figure 1 , Figure 5 and Figure 6 As shown, the trenching component 7 includes a support frame 71, and trenchers 72 are installed on the left, right and middle sides of the bottom of the support frame 71. The filling component 8 includes a support frame 81, and fillers 82 are installed on the left, right and middle sides of the bottom of the support frame 81. The support frame 71 and the support frame 81 are respectively located on the front and rear sides of the top of the vehicle frame 11.

[0050] Both height adjustment components 9 include a support base 91. Electric push rods 92 are symmetrically fixedly installed on the top of the support base 91. The two electric push rods 92 located at the same end are respectively fixedly installed on the left and right sides of the bottom middle position of the support frame 71 or support frame 81 at the same end.

[0051] In this solution, both electric actuator 1 (52) and electric actuator 2 (92) can be the Dongyuxiang YMD602 electric actuator, which has a built-in limit switch, supports stroke control, supports communication with PLC, and is suitable for industrial equipment that requires precise control of the telescopic rod stroke.

[0052] The main control box 53 includes an outer box, an electric linear actuator controller, and a main controller, as in the prior art. Both support bases 91 have integrated electric linear actuator controllers. The electric linear actuator controllers at these two locations can be DC motor linear actuator controllers that are compatible with the Dongyuxiang YMD602 model in the prior art. These controllers have PWM speed regulation and forward and reverse rotation control functions. The main controller at the main control box 53 can be a PLC main controller in the prior art.

[0053] The cylinders of the two electric push rods 92 are respectively hinged or fixed to the corresponding positions of the two support bases 91. The top of the telescopic rod of one of the electric push rods 92 is connected to the support frame 71 of the trenching component 7, and the top of the telescopic rod of the other electric push rod 92 is connected to the support frame 81 of the backfilling component 8.

[0054] This structural design allows for independent adjustment of two key parameters: furrowing depth and backfill pressure. Operators can precisely set the cutting depth of the furrow opener 72 according to soil conditions and agronomic requirements to ensure that seeds are in the best growing environment.

[0055] Meanwhile, the downward pressure of the filler 82 can be independently adjusted to obtain the ideal soil compaction. It should be noted that the specific structure of the furrow opener 72 and the filler 82 in this embodiment is not an innovation of this utility model. Those skilled in the art can choose any known furrow opener (such as a double disc type or hoe type furrow opener) and filler (such as a rubber wheel type, soil covering plate type, or V-type press wheel filler) that can be adapted to the seeding component 4 to achieve its function.

[0056] Working principle: The operator first sets the sowing parameters through the main control box 53, and then pushes the device along the ridge by holding the handle 2;

[0057] During the process, the ditching component 7 first digs a seed trench in the soil; at the same time, the main controller precisely drives the motors of each seeding component according to the forward speed of the unit, so that the seed metering device 41 accurately puts the seeds in the collection box 43 into the seed trench through the conveying hopper 42 and the seed guide tube; then, the soil filling component 8 covers the seed trench with soil and compacts it.

[0058] During operation, the operator can independently control the two height adjustment components 9 to adjust the trenching depth and soil compaction in real time to adapt to soil conditions. The operator can also independently drive the three seeding components 4 to move longitudinally through the front and rear adjustment components 5 to form a staggered layout, thereby optimizing the plant canopy structure and improving ventilation and light.

[0059] When a transfer is needed, simply pull up handle 2 to lift the auxiliary rear wheel 14 and the working parts off the ground, leaving only the front wheel 13 on the ground, thus enabling convenient transfer.

[0060] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
