Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a corn planting device for mountainous areas. Background Technology

[0002] Currently, most corn planting machinery is designed for plains areas and relies on gasoline or diesel engines for power, which has the following limitations:

[0003] (1) Poor terrain adaptability: Traditional seeders are large and heavy, making it difficult to move stably in complex terrains such as mountains and slopes. They are prone to side slip or overturning, especially when operating on steep slopes.

[0004] (2) High dependence on power: fuel-powered vehicles require frequent maintenance, and the engine is prone to stalling in areas with steep slopes, leading to interruption of sowing;

[0005] (3) Insufficient sowing precision: Most existing machinery adopts a single-row sowing structure with uneven sowing spacing and lacks an integrated design for trenching and covering soil, requiring manual secondary trimming, which is inefficient.

[0006] Therefore, there is an urgent need for a lightweight, fuel-free corn planting device that can adapt to mountainous terrain to solve the above problems. Utility Model Content

[0007] In order to overcome the problems in the prior art, this utility model provides a corn planting device for mountainous areas.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0009] A corn planting device for mountainous areas includes a frame and a planting mechanism. The frame includes a main frame and a drive rod. The main frame has a rectangular structure with symmetrical mounting rings at the middle of its two long rods. Drive bearings are embedded in the mounting rings. Drive wheels are located on both sides of the main frame, and a drive shaft passes through the drive bearings in the middle of the drive wheels. The drive rod is L-shaped and vertically welded to the middle of the front rod of the main frame. A tie rod is horizontally fixed at the end of the drive rod. Two sets of planting mechanisms are symmetrically arranged, each mounted on a drive shaft mounted on the main frame and located inside the main frame. Each planting mechanism includes a shell, an inner circular plate, a seed cylinder, and a seed lowering tube. The inner circular plate has a central hole and is connected to the drive shaft via a rotating bearing. The shell covers the inner circular plate and... The inner circular plate forms an annular gap with the outer shell; the two sides of the inner circular plate are tightly fitted to the inner wall of the outer shell cavity, and multiple inoculation grooves are evenly distributed around its arc surface. The edge of the inoculation groove closest to the inner cavity of the outer shell contacts the inner wall of the outer shell; a seed cylinder is provided at the top of the outer shell, and the seed cylinder is connected to the annular gap between the arc surface of the inner circular plate and the outer shell through a feeding pipe. The diameter of the feeding pipe is only large enough for a single corn seed to pass through; a discharge port is provided at the bottom of the outer shell corresponding to the end of the rotation trajectory of the inoculation groove, and the discharge port is connected to the feeding pipe; when the drive wheel drives the drive shaft to rotate, the inner circular plate rotates synchronously, and the corn seeds fall into the annular gap through the feeding pipe in sequence and are captured by the inoculation groove. After rotating with the inner circular plate to the discharge port, they leave the inoculation groove due to gravity and fall into the soil through the feeding pipe, thus achieving evenly spaced sowing.

[0010] Furthermore, a trenching mechanism is symmetrically provided below the front rod of the frame, including two connecting rods that are vertically fixed to the front rod. Two trenching wheels are installed at the bottom of each connecting rod. The two trenching wheels are arranged at a V-shaped angle, with their adjacent wheel surfaces facing the pull rod side, for simultaneously digging two parallel trenches before sowing.

[0011] Furthermore, a soil covering mechanism is symmetrically provided below the rear rod of the frame, including two mounting rods that are vertically fixed to the rear rod. A soil covering wheel is installed at the bottom of the mounting rod. The width of the soil covering wheel is greater than the width of the outer shell, and its axis is collinear with the outlet of the seeding tube, which is used to compact the soil covering the corn seeds that fall into the trench.

[0012] Furthermore, a reinforcing rib is provided between the drive rod and the pull rod, and anti-slip grips are provided at both ends of the pull rod.

[0013] Furthermore, the depth of the inoculation groove is 1.2-1.5 times the diameter of the corn seed, and its opening width is adapted to the length of the corn seed.

[0014] Furthermore, a fixing component is installed on the main frame. The fixing component consists of a fixing rod and a fixing ring. The fixing rod is fixed to the main frame, and the fixing ring is fitted onto the seed cylinder to achieve fixation.

[0015] The beneficial effects of this utility model are:

[0016] This utility model significantly improves the efficiency and applicability of sowing in mountainous areas through the following design:

[0017] (1) Fully human-powered: It adopts a two-person pulling operation, requires no fuel power, and has a lightweight design (total weight ≤30kg) which is convenient for mountain transport and has high stability when operating on steep slopes.

[0018] (2) Symmetrical double-row sowing: Two sets of sowing mechanisms work synchronously, sowing two rows at a time with uniform spacing, increasing sowing efficiency by more than 50%.

[0019] (3) Integrated operation: integrates ditching, sowing and covering functions, reduces manual intervention, ensures consistent sowing depth, and achieves a seed covering and soil compaction rate of over 95%.

[0020] (4) Structural anti-overturning: Triangular reinforcing ribs are provided between the drive rod and the push rod, and the two ends of the push rod are covered with anti-slip rubber layer to ensure that the device is not easily deflected when farmers apply force on the slope.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] See Figures 1 to 6This utility model discloses a corn planting device for mountainous areas, including a frame 1 and a planting mechanism 2. The frame 1 includes a main frame 11 and a drive rod 12. The main frame 11 has a rectangular structure, with mounting rings symmetrically arranged in the middle of the long rods on both sides. A drive bearing is embedded in the mounting ring 14. Drive wheels 5 are arranged on both sides of the main frame 11, and a drive shaft 51 in the middle of the drive wheel 5 passes through the drive bearing. The drive rod 12 is L-shaped and is vertically welded to the middle of the front rod of the main frame 11. A pull rod 13 is horizontally fixed at the end of the drive rod 12. The planting mechanism 2 is symmetrically arranged in two sets, respectively installed on the drive shaft 41 installed on the main frame 11 and located inside the main frame 11. Each set of planting mechanism 2 includes a shell 21, an inner circular plate 22, a seed cylinder 23, and a seed tube 24. The inner circular plate 22 has a circular hole in the center and is sleeved on the drive shaft 51 through a rotating bearing 222. The shell 21 covers the inner circular plate 22 and... The inner circular plate 22 forms an annular gap with the outer shell 21. The two sides of the inner circular plate 22 are tightly fitted to the inner wall of the outer shell 21. Multiple inoculation grooves 221 are evenly distributed around its arc surface. The edge of the inoculation groove 221 closest to the inner cavity of the outer shell 21 contacts the inner wall of the outer shell 21. The top of the outer shell 21 is provided with a seed cylinder 23. The seed cylinder 23 is connected to the annular gap between the arc surface of the inner circular plate 22 and the outer shell 21 through a feeding pipe 231. The aperture of the feeding pipe 24 is only large enough for a single corn seed to pass through. The bottom of the outer shell 21 is provided with a discharge port 211 at the end of the rotation trajectory of the inoculation groove 221. The discharge port 211 is connected to the feeding pipe 24. When the drive wheel 5 drives the drive shaft 51 to rotate, the inner circular plate 11 rotates synchronously. The corn seeds fall into the annular gap through the feeding pipe 231 and are captured by the inoculation grooves 221. After rotating with the inner circular plate 22 to the discharge port 211, they leave the inoculation grooves 221 due to gravity and fall into the soil through the feeding pipe 24, thus achieving evenly spaced sowing.

[0032] It should be noted that frame 1: The main frame 11 is welded from 40mm×40mm square steel pipes into a rectangle (1.8m long, 0.6m wide). Symmetrical mounting rings 14 (50mm inner diameter) are welded to the middle of the long rods on both sides, with drive bearings (model 6205) embedded within the mounting rings 14. Drive shafts 51 (20mm diameter) pass through the bearings and connect to the drive wheels 5 (35cm diameter, rubber tread) on both sides. An L-shaped drive rod 12 (1.2m high, 3mm wall thickness) is vertically welded to the middle of the front rod of the main frame 11, with a tie rod 13 (1.5m long, 30mm diameter) laterally fixed at the end of the drive rod 12.

[0033] The corn is stored in the seed cylinder 23. When in use, the corn is conveyed from the feed pipe 231. The feed pipe 231 allows only one kernel of corn to pass through at a time. In this way, the corn is conveyed sequentially into the annular gap formed by the outer shell 21 covering the inner circular plate 22 and is captured by the inoculation groove 221. After rotating with the inner circular plate 22 to the discharge port 211, it is released from the inoculation groove 221 by gravity and falls into the soil through the seeding pipe 24, thus achieving equidistant sowing.

[0034] Example 2

[0035] See Figure 1 , Figure 2 , Figure 3 As shown, a trenching mechanism 3 is symmetrically provided below the front rod of the frame 1, including two connecting rods 31 that are vertically fixed to the front rod. Two trenching wheels 32 are installed at the bottom of each connecting rod 31. The two trenching wheels 32 are arranged at a V-shaped angle, and their adjacent wheel surfaces face the side of the pull rod 13, which is used to dig two parallel trenches simultaneously before sowing.

[0036] In this embodiment, the furrowing mechanism 3 includes two connecting rods 31 (40cm long, 25mm in diameter) vertically welded to the bottom of the front rod of the main frame. Two furrowing wheels 32 (15cm in diameter, 60° cutting edge angle) are bolted to the bottom of each connecting rod 31. The two furrowing wheels 32 are arranged at a V-shaped angle (50°), with adjacent wheel surfaces facing the push rod. During operation, the furrowing wheels 32 cut into the soil (6-10cm deep), simultaneously excavating two parallel furrows (15cm apart) with a furrow width of 5cm, providing precise positioning for subsequent sowing.

[0037] Example 3

[0038] See Figure 1 , Figure 2 , Figure 3 As shown, a soil covering mechanism 4 is symmetrically provided below the rear rod of the frame 1, including two mounting rods 41 that are vertically fixed to the rear rod. A soil covering wheel 42 is installed at the bottom of the mounting rod 41. The width of the soil covering wheel 42 is greater than the width of the outer shell 21, and its axis is collinear with the outlet of the seeding tube 24. It is used to compact the soil covering the corn seeds that fall into the trench.

[0039] In this embodiment, the soil covering mechanism 4 includes two mounting rods 41 (35cm long, 25mm in diameter) vertically welded to the lower part of the rear rod of the main frame 11. A soil covering wheel 42 (20cm in diameter, 12cm wide, made of cast iron) is mounted on the bottom of the mounting rods 41 via a rotating shaft. The axis of the soil covering wheel 42 is collinear with the outlet of the seeding tube 24, and its width is greater than the width of the outer casing 21 (10cm), ensuring that the soil covering area completely covers the sowing furrow. During operation, the soil covering wheel 42 moves with the device to backfill and compact the soil on both sides of the furrow, with a soil covering thickness of 2-3cm and a seed burial depth consistency error ≤5%.

[0040] Example 4

[0041] See Figure 1 , Figure 2 , Figure 3As shown, a reinforcing rib 131 is provided between the drive rod 12 and the pull rod 13, and anti-slip grips 132 are provided at both ends of the pull rod 13. The depth of the inoculation groove 221 is 1.2-1.5 times the diameter of the corn seed, and its opening width is adapted to the length of the corn seed. A fixing component 6 is installed on the main frame 11. The fixing component 6 consists of a fixing rod 61 and a fixing ring 62. The fixing rod 61 is fixed to the main frame 11, and the fixing ring 62 is fitted onto the seed cylinder 23 for fixation.

[0042] In this embodiment, a triangular reinforcing rib 131 (15cm side length, 5mm thick steel plate) is welded at the connection between the drive rod 12 and the pull rod 13 to improve the torsional strength of the structure. Both ends of the pull rod 13 are covered with an anti-slip rubber layer (5mm thick, diamond-patterned surface), providing a 20cm gripping area and increasing friction by 40%, preventing farmers from slipping their hands when pushing the rod on slopes. The inoculation groove 221 has a depth 1.3 times the diameter of the corn seed (12mm), and its opening width matches the seed length (8mm). The inner wall of the groove has an arc-shaped guide surface (4mm radius of curvature) to reduce the risk of seed jamming. Testing showed a single-groove seed capture success rate of 98% and a missed seeding rate of ≤2%. To ensure the stability of the seed cylinder 23, it is fixed by a fastener 6, with a fixing ring 62 securing the seed cylinder 23, thus preventing it from shaking and falling off the device, achieving component installation stability.
