Description

Technical Field

[0001] This utility model relates to the field of corn planting, and in particular to a handheld corn planting device for hard soil. Background Technology

[0002] Currently, for sowing in small cornfields, experimental corn fields, and hillside farmland, portable, manually operated seeders are typically used, as large, tractor-mounted seeders cannot be deployed in such areas. Patent CN117242949A discloses a manually operated seeder with a duckbill-shaped seeding funnel at the bottom that can open and close to sow seeds within the soil. This seeding structure is primarily suitable for soft soil after plowing and harrowing. However, some farmlands reduce tillage frequency to avoid soil erosion and water loss, resulting in harder, uncultivated soil. Using the aforementioned manually operated seeder presents a problem: the duckbill-shaped seeding funnel has difficulty opening, leading to poor seed distribution and ineffective sowing. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a handheld corn planting device for hard soil.

[0004] The technical solution of this utility model is: a handheld corn planting device for hard soil, comprising long grooved planing teeth and a hollow rod. The cross-section of the long grooved planing teeth gradually decreases from top to bottom. A grooved seat is provided at the upper end of the long grooved planing teeth, and the grooved seat is vertically and integrally connected to the long grooved planing teeth. The hollow rod is connected to the end plate of the grooved seat, requiring sufficient fixing strength between the rod and the end plate. A through hole matching the size of the corn seeds is provided in the middle of the end plate, and a seed dispensing cylinder is connected to the through hole. The inner side of the long grooved planing teeth is provided with a support. The support is L-shaped, with a long guide rod vertically connected to the base plate. The upper end of the long guide rod is fixedly connected to the top plate of the support. A sealing plate is provided on the outside of the long groove teeth, which slides against the outer surface of the long groove teeth. The upper end of the sealing plate is provided with a sliding plate that slides against the long guide rod. A spring is fitted on the long guide rod between the sliding plate and the base plate. The upper end of the sealing plate is provided with an L-shaped sealing plate that slides against the outer port of the seed metering cylinder. A discharge port matching the size of the seed metering cylinder port is provided in the middle of the L-shaped sealing plate.

[0005] Preferably, the outer side of the support base is provided with a secondary planer tooth with the same shape and size as the long slot planer tooth. The secondary planer tooth and the long slot planer tooth are arranged symmetrically. The outer side of the sealing plate is integrally connected with a secondary plate body. The secondary plate body and the sealing plate are arranged symmetrically. The upper end of the secondary planer tooth is provided with a square base body. A connector pipe communicating with the internal cavity of the square base body is connected to the end face of the square base body. A fertilizer hose is connected to the connector pipe. The fertilizer hose and the connector pipe are fixedly connected by a pipe clamp.

[0006] Preferably, the lower part of the inner end of the connector tube is provided with an arc-shaped baffle, which forms a semi-circular fertilizer outlet.

[0007] Preferably, a counterweight is fixedly connected between the sub-plate and the sealing plate by screws, and the counterweight is fixed at the exact center between the sub-plate and the sealing plate.

[0008] Preferably, the upper surface of the seed metering cylinder is provided with a plurality of square observation holes evenly distributed from one end to the other, and the observation holes are square holes arranged along the width direction of the seed metering cylinder.

[0009] Preferably, the inner side of the bend of the L-shaped sealing plate is provided with a reinforcing plate A, and a reinforcing plate B is provided between the sealing plate and the sliding plate. Both reinforcing plate A and reinforcing plate B are triangular plates and are connected by welding.

[0010] Preferably, the outer end of the fertilizer hose is connected to a fertilizer bag or fertilizer box, and the height of the fertilizer bag or fertilizer box is higher than the height of the lower end of the fertilizer hose.

[0011] The beneficial technical effects of this utility model are as follows: The device uses a hollow rod to insert the long grooved planer teeth into the soil. When the planer inserts into the soil, the sealing plate compresses the spring and slides downward under the action of impact inertia. The L-shaped sealing plate moves accordingly to open the seed outlet. The corn seeds slide down into the long grooved planer teeth under the action of inertia and then into the soil. This method of sowing by digging the ground has a large impact force and does not have the phenomenon of the duckbill-shaped funnel not being able to open in the soil. It can be well adapted to sowing in hard soil and can effectively avoid the phenomenon of poor seed outlet affecting the sowing effect, thus ensuring the emergence rate of corn seeds.

Detailed Implementation

[0018] Example 1, see appendix Figure 1-5 A handheld corn planting device for hard soil includes long grooved planing teeth 1 and a hollow rod 3. The cross-section of the long grooved planing teeth gradually decreases from top to bottom, gradually forming a pointed tooth structure. A grooved seat 11 is provided at the upper end of the long grooved planing teeth. The hollow rod 3 is connected to the end plate of the grooved seat 11 and welded to the end plate. A through hole matching the size of the corn seed is provided in the middle of the end plate. Only one seed will slide out of the through hole due to inertia with each impact. A seed metering cylinder 4 is matched and connected at the through hole. The seed slides out of the through hole and enters the seed metering cylinder 4. A support seat 5 is provided on the inner side of the long grooved planing teeth 1. A long guide rod 53 is vertically connected to the bottom plate 51 of the support seat 5. The direction of the long guide rod is consistent with the length direction of the long grooved planing teeth. The upper end of the long guide rod 53 is connected to the support seat 5. The top plate 52 is fixedly connected, and a sealing plate 61 is provided on the outside of the long grooved teeth 1. The sealing plate forms a sliding sealing structure on the outside of the long grooved teeth. The upper end of the sealing plate 61 is provided with a sliding plate 63 that is slidably connected to the long guide rod 53. A spring 54 is fitted on the long guide rod between the sliding plate and the bottom plate. The spring 54 provides elastic support for the sealing plate 61, so that the sliding plate 63 will compress the spring 54 due to inertia after being impacted and slide down along the long guide rod 53. The upper end of the sealing plate 61 is provided with an L-shaped sealing plate 64 that slides against the outer port of the seed metering cylinder 4. The middle of the L-shaped sealing plate is provided with a discharge port 65. During the downward sliding of the sealing plate 61, the air discharge port 65 will coincide with the outlet of the seed metering cylinder 4. At this time, the seeds slide out from the discharge port to achieve quantitative sowing.

[0019] A counterweight 8 is fixedly connected between the sub-plate 62 and the sealing plate 61 by screws. The counterweight increases the weight of the sealing plate, resulting in greater inertia and ensuring that it can smoothly compress the spring 54 and slide downward.

[0020] Several square observation holes 41 are evenly provided on the upper surface of the seed metering cylinder 4 from one end to the other. The movement of seeds in the seed metering cylinder can be observed through these observation holes, which helps to detect seed metering problems or even blockages in a timely manner.

[0021] The inner side of the bend of the L-shaped sealing plate 64 is provided with a reinforcing plate A 91, which improves the deformation control strength of the L-shaped sealing plate. A reinforcing plate B 92 is provided between the sealing plate 61 and the sliding plate 63, which improves the structural strength of the sealing plate.

[0022] When using this sowing device, corn seeds are loaded into the hollow rod 3, and the outer end of the fertilizer hose 7 is connected to the fertilizer belt or fertilizer box carried on the person. Then, the hollow rod 3 is held down and the long grooved teeth 1 at the outer end are driven into the soil. The hollow rod itself generates impact inertia, which causes the seeds inside the hollow rod 3 to slide downwards into the seed dispensing cylinder 4. At the same time, the sealing plate 61 compresses the spring 54 and slides downwards under the action of inertia. The L-shaped sealing plate 64 moves accordingly. When its discharge port 65 corresponds to the outer port of the seed dispensing cylinder 4, the corn seeds are discharged and fall between the sealing plate 61 and the long grooved teeth 1 into the soil. After the inertia disappears, the rebound force of the spring 54 drives the sealing plate 61 to return to its original position. The L-shaped sealing plate 64 moves accordingly to seal the outer port of the seed dispensing cylinder 4, and the seeds no longer discharge, thus achieving quantitative sowing.

[0023] Example 2, see appendix Figure 1-4 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the outer side of the support base 5 is provided with a secondary planer tooth 2 with the same shape and size as the long groove planer tooth 1, and the outer side of the sealing plate 61 is integrally connected with a secondary plate body 62. The secondary plate body and the sealing plate are arranged symmetrically. The upper end of the secondary planer tooth 2 is provided with a square base body 21. A connector pipe 22 communicating with the internal cavity of the square base body 21 is connected to the end face of the square base body. A fertilizer hose is connected to the connector pipe. The outer end of the fertilizer hose 7 is connected to the fertilizer bag or fertilizer box. The connector pipe 22 and the fertilizer hose 7 are fixed by a hoop to ensure the stability of the connection and avoid falling off due to vibration. The lower part of the inner end of the connector pipe 22 is provided with an arc-shaped baffle 23, which forms a semi-circular fertilizer outlet 24.

[0024] During the sowing process, under the influence of impact inertia, fertilizer slides from fertilizer hose 7 into connector pipe 22. Under the influence of inertia, some fertilizer rolls over arc baffle 23 and enters the soil between sub-plate 62 and sealing plate 61. Fertilizer can be applied to one side of the seed simultaneously, thus achieving simultaneous corn sowing and fertilization.
