Detailed Implementation

[0024] To facilitate understanding of this utility model, the following description will be provided in more comprehensive and detailed manner with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0025] like Figure 1-4As shown, this utility model discloses a broad bean sowing device, including a walking chassis 1, a duckbill sowing device 2 and a seed box 3 installed on the walking chassis 1. The walking chassis 1 is equipped with a battery 12, a motor 13 and a control cabinet 14 that are connected to each other. The motor 13 is connected to the walking chassis 1, the duckbill sowing device 2 and the seed box 3. The duckbill seeding device 2 includes a seeding duckbill 21, a duckbill opening and closing drive assembly 22, a drive chain 23, and a drive chain drive assembly 24. The drive chain drive assembly 24 includes a motor 13, a drive shaft, and a drive sprocket. The motor 13 drives the drive chain 23, which is engaged with the drive sprocket. The battery 12 supplies power to the motor 13. The seeding duckbill 21 includes a duckbill mounting base 211, a first half-duckbill 212, and a second half-duckbill 213. One end of the bottom of the first half-duckbill 212 and the second half-duckbill 213 is hinged to the duckbill mounting base 211, and the other end is hinged to each other. The tops of the first half-duckbill 212 and the second half-duckbill 213 form a conical tip. The duckbill mounting base 211 is connected to the drive chain 23. The duckbill opening and closing drive assembly 22 drives the first half-duckbill 212 and the second half-duckbill 213 to open below the seed box 3 and after vertical insertion into the soil. This invention solves the problem of vertical drilling during planting by controlling the first and second halves of the duckbill (212 and 213) to automatically insert themselves vertically into the soil and then open. This reduces soil disturbance and ensures the hole size remains consistent with the desired dimensions. It significantly reduces the impact of undue pressure on soil particles within the holes, minimizing the influence on seedling planting and growth, and greatly improving the quality of transplanted plants. It also makes sowing more precise and reduces soil porosity, which is beneficial for crop growth and development, increasing yield and quality.

[0026] In this embodiment, in order to open the first half-duckbill 212 and the second half-duckbill 213 after they are vertically inserted into the soil, the movement direction of the walking chassis 1 and the lower chain of the drive chain 23 are opposite and the speed is equal, so as to reduce unnecessary disturbance caused by the front and rear displacement of the first half-duckbill 212 and the second half-duckbill 213 when they are inserted, and improve the accuracy of hole formation.

[0027] In this embodiment, the duckbill opening and closing drive assembly 22 includes a duckbill opening and closing guide rail 221 and a return spring 226. The first half-duckbill 212 and the second half-duckbill 213 are kept closed by the return spring 226, thereby preventing the seeds that have entered the first half-duckbill 212 and the second half-duckbill 213 from slipping out. The other ends of the first half-duckbill 212 and the second half-duckbill 213 are hinged by a hinge shaft 214. The hinge shaft 214 is located on both sides of the first half-duckbill 212 and the second half-duckbill 213. The end of the hinge shaft 214 is intermittently engaged with the duckbill opening and closing guide rail 221 to open and close the first half-duckbill 212 and the second half-duckbill 213. That is, when the end of the hinge shaft 214 is engaged with the duckbill opening and closing guide rail 221, the opening-holding-closing actions are completed.

[0028] In this embodiment, the duckbill opening and closing guide rail 221 includes an inclined lift end 223 for driving the first half duckbill 212 and the second half duckbill 213 to open, a horizontal stabilizing section 224 for keeping the first half duckbill 212 and the second half duckbill 213 open, and an inclined return section 225 for closing the first half duckbill 212 and the second half duckbill 213, forming a trapezoidal structure. Optionally, the inclined return section 225 can be omitted, that is, the first half duckbill 212 and the second half duckbill 213 close quickly.

[0029] In this embodiment, the end of the hinge shaft 214 is provided with a rolling bearing 215 that rolls with the duckbill opening and closing guide rail 221, thereby replacing sliding friction with rolling friction, preventing mutual frictional wear, and improving the fitting accuracy and durability.

[0030] In this embodiment, one end of the return spring 226 is connected to the first half-duckbill 212 and the other end is connected to the second half-duckbill 213. The bottom of the first half-duckbill 212 and the second half-duckbill 213 are provided with a hanging ear 227 for hooking the return spring 226. When the hinge shaft 214 is disengaged from the duckbill opening and closing guide rail 221, the first half-duckbill 212 and the second half-duckbill 213 close under the pulling force of the return spring 226.

[0031] In this embodiment, the seed box 3 includes a seed metering chain 31, a seed metering chain drive assembly 32, and a seed metering spoon 33. The seed metering spoon 33 is mounted on the seed metering chain 31. The seed metering chain drive assembly 32 drives the seed metering spoon 33 on the seed metering chain 31 to pass above the sowing duckbill 21, so that the seeds slide off the seed metering spoon 33.

[0032] In this embodiment, since the first half-billed 212 and the second half-billed 213 need to have a rotational clearance with the bill mounting base 211, in order to prevent the seeds from sliding out of the clearance, the bill mounting base 211 is provided with an inoculation cup 216. The inoculation cup 216 is located inside the first half-billed 212 and the second half-billed 213, so as to keep the seeds from sliding out from the bottom of the first half-billed 212 and the second half-billed 213 after falling into them.

[0033] In this embodiment, since the drive chain 23 has certain flexible deformation characteristics, in order to ensure that the first half-duckbill 212 and the second half-duckbill 213 are inserted into the soil with a certain rigidity, limiting ring guide rails 11 are installed on the opposite mounting plates 15 on the walking chassis 1. The limiting ring guide rails 11 are in the shape of a racetrack, and the bottom of the duckbill mounting base 211 is provided with clamping guide wheels 217, which cooperate with the inner and outer sides of the limiting ring guide rails 11. Optionally, other limiting guide rail structures can also be installed between the limiting ring guide rails 11 to further improve the support rigidity.

[0034] The working process of this broad bean sowing device is as follows:

[0035] S1. The seed metering chain 31 with seed metering spoon 33 quantitatively removes 2-4 seeds from the seed box 3 and sends the seeds from the seed metering device to the planting device.

[0036] S2. When the sowing duckbill 21 moves to the bottom of the seed metering device, it opens under the action of the duckbill opening and closing guide rail 221, and the seeds fall into the sowing duckbill 21, which has a bowl-shaped inoculation cup 216 inside. As the machine runs, the sowing duckbill 21 closes under the action of the duckbill opening and closing guide rail 221 and the return spring 226, and the seeds are stored in the sowing duckbill 21.

[0037] S3. As the machine operates, the sowing nozzle 21 is transported to the bottom of the planting device. Through a special guide rail path design that moves in the opposite direction to the overall mechanical movement, the sowing nozzle 21 remains stationary relative to the ground and moves downwards, vertically drilling a conical hole with a diameter of 150mm and a depth of 150mm as the machine travels. When the sowing nozzle 21 reaches the bottom of the seeder, it opens under the action of the nozzle opening and closing guide rail 221, allowing the seeds to fall accurately into the bottom of the hole. Then, the sowing nozzle 21 continues to open and move upwards.

[0038] S4. As the machine operates, the sowing duckbill 21 will close and leave the soil under the action of the spring return spring 226, and then move upward along the guide rail to enter a new cycle.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
