Specific embodiments

[0053] The above content of the present invention will be further described in detail through the following embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0054] Embodiment 1: Refer to Figure 1-4, is a structural schematic diagram of Example 1 of the present invention. This embodiment discloses a melon seed drill, comprising a drill shaft (14) and a seed discharge box (18). A shell (16), a seed removal plate and a seed discharge cam (9) are sleeved on the drill shaft (14). The seed removal plate can rotate on the drill shaft (14). The shell (16) and the seed discharge cam (9) are fixed. A seed lowering tube (13) is provided on one side of the shell (16). The seed removal plate is an annular plate-shaped body. One side is a seed chamber (20), and the other side is provided with a release plate placement groove (6) on the seed taking plate surface, the seed taking plate is provided with a slot hole (21) near the outer edge, a seed taking nest (2) is provided on the seed taking plate at the outer edge of the slot hole (21), the center of the seed taking nest (2) faces the center of the seed taking plate, a release plate (7) is provided in the release plate placement groove (6), a seed taking space is provided between the seed taking nest (2) and the release plate (7), and the seed discharge box (18) is provided on the release plate side of the slot hole (21).

[0055] The seed discharging box (18) is arranged at the outer edge of the seed taking plate. The cross section of the seed discharging box (18) is T-shaped, and the lower part is a seed box that can be received at the slot hole (21). The release plate (7) swings the seeds to be discharged from the seed taking nest (2) into the seed box. A sowing duckbill can be arranged on the outer side of the seed discharging box (18), and the seed box is connected to the duckbill.

[0056] A seeding wheel adjustment hole (16-2) is provided on the surface of the housing (16), and a bolt is inserted into the seeding wheel adjustment hole (16-2) to connect the housing (16) and the seeding cam (9) into a whole.

[0057] The middle part of the release plate (7) is hinged on the seed taking plate, and a pulley (4) is provided at one end. When the pulley (4) passes the protrusion of the seed discharge cam (9), it drives the release plate (7) to swing around the hinge part, and the swing of the release plate (7) realizes the discharge of seeds from the seed taking nest (2).

[0058] A tension spring (8) is provided between the release plate (7) and the seed taking plate. When the release plate (7) is under the tension of the tension spring (8), the seed taking nest (2) is blocked in a normal state. When the pulley (4) passes through the seed discharge cam (9), it is subjected to an external force and the release plate (7) swings to expose the seed taking nest (2) to discharge seeds.

[0059] As an improvement, the seeding wheel adjustment hole (16-2) is in the shape of a strip, and a bolt can be squeezed into different positions of the seeding wheel adjustment hole (16-2) to achieve angle adjustment of the seeding cam (9). The angle of the seeding cam (9) is adjusted to adjust the position of the protrusion on the outer edge of the seeding cam (9), and its purpose is to adjust the timing when the pulley (4) of the release plate (7) contacts the protrusion, thereby achieving control and adjustment of the seeding timing.

[0060] During actual use: A seeding nozzle is installed outside the seeding box (18). As the hill-drop drill rotates, seeds enter the seed-taking cavity (2) from below. As the seed-taking plate rotates, the release plate (7) opens, and the seeds in the seed-taking cavity (2) are discharged into the seeding box (18). Finally, the seeds are sown by the seeding nozzle. The seeds are put into the seed chamber through the seed tube (13).

[0061] Embodiment 2: Compared with Embodiment 1, the difference in this embodiment is that: One side plate surface of the slot hole (21) is provided with a slope surface (22), and the slope surface (22) inclines towards the slot hole (21). The inclined surface (22) is arranged on one side of the seed chamber (20). The slope surface (22) inclining towards the notch means that the end far from the notch is thicker and the end close to the notch is thinner.

[0062] Embodiment 3: Compared with any one of Embodiments 1-2, the difference in this embodiment is that: The structure of the seed metering cam (9) is as follows: It includes a seed metering cam (9). The surface of the seed metering cam (9) is provided with mounting holes. The seed metering cam (9) is annular. The outer edge of the seed metering cam (9) is provided with a pulley track (9-1), and a through hole for fixing the hill-drop drill shaft (14) is provided at the center. A chuck groove (9-4) is further provided at the edge of the seed metering cam (9). A cam chuck (11) is arranged in the chuck groove (9-4). One end of the cam chuck (11) is hinged to the seed metering cam (9) through a chuck shaft (9-2), and a spring (10) is arranged between the cam chuck (11) and the seed metering cam (9). The cam chuck (11) can be retracted into the chuck groove (9-4) under an external force, and can protrude from the chuck groove (9-4) under the action of the spring (10) when the external force disappears.

[0063] During actual use: When the pulley (4) moving along the pulley track (9-1) approaches the cam chuck (11) from the direction of the chuck shaft (9-2) where the cam chuck (11) is connected to the seed metering cam (9), the cam chuck (11) can be squeezed into the chuck groove (9-4). When approaching the cam chuck (11) from the direction away from the chuck shaft (9-2) where the cam chuck (11) is connected to the seed metering cam (9), the cam chuck (11) cannot be squeezed into the chuck groove (9-4), and the cam chuck (11) can drive the release plate (7) to swing. Through this structural design, the mechanism can distinguish between forward and reverse rotations. Forward rotation means that the pulley (4) contacts the cam chuck from the direction away from the chuck shaft (9-2), and the cam chuck (11) cannot be squeezed into the chuck groove (9-4), realizing the swing of the release plate (7). Reverse rotation means that the pulley (4) contacts the cam chuck from the direction close to the chuck shaft (9-2), and the cam chuck (11) can be squeezed into the chuck groove (9-4), and the swing of the release plate (7) cannot be realized. By distinguishing between forward and reverse rotations, the purpose of seeding during forward rotation and not seeding during reverse rotation is achieved.

[0064] Example 4: Compared with any one of Examples 1 - 3, the difference in this example is that: the cam chuck (11) is provided with a convex head (11 - 3), and the chuck groove (9 - 4) is provided with a notch (9 - 3). When the cam chuck (11) retracts into the chuck groove (9 - 4), the convex head (11 - 3) can enter the notch (9 - 3), and the spring (10) is arranged on the convex head (11 - 3) and the notch (9 - 3).

[0065] Example 5: Compared with any one of Examples 1 - 4, the difference in this example is that: the outer edge of the cam chuck (11) is provided with a contact surface A (11 - 1) and a contact surface B (11 - 2). The contact surface A (11 - 1) and the contact surface B (11 - 2) are arc-shaped surfaces, and the arc-shaped surfaces face the pulley track (9 - 1). When a pulley (4) on the pulley track (9 - 1) moves towards and disengages from the cam chuck (11), the arc-shaped surface serves as the contact surface for the pulley (4) to contact the cam chuck (11). The arc-shaped surface design can avoid hard contact.

[0066] Example 6: Refer to Figures 36-38 , which is a schematic structural diagram of Example 6 of the present invention. Compared with Examples 1 - 5, the difference in this example is that: the seed metering wheel adjustment hole (16 - 2) is strip-shaped, and a seed metering timing adjustment plate (24) is provided on the outer surface of the housing (16). The seed metering timing adjustment plate (24) is plate-shaped or sheet-shaped. The seed metering timing adjustment plate (24) is provided with a bolt hole (24 - 1), a hill-drop drill shaft mounting hole (24 - 3), and a handle (24 - 5). The bolt passes through the bolt hole (24 - 1) and the seed metering wheel adjustment hole (16 - 2) in sequence and is connected to the seed metering cam (9). When it is necessary to adjust the position of the seed metering cam (9), only the bolt needs to be loosened, and the handle (24 - 5) is operated to drive the seed metering cam (9) to rotate. When fixing, only the bolt needs to be tightened.

[0067] Example 7: Refer to Figures 5-8 and Figure 13 , which is a schematic structural diagram of Example 7 of the present invention. This example discloses a seed-taking mechanism used on a seed melon hill-drop drill, including a seed-taking plate. The seed-taking plate is an annular plate-like body, and a slot hole (21) is provided near the outer edge. A seed-taking cavity (2) is provided on the seed-taking plate at the outer edge of the slot hole (21). The center of the seed-taking cavity (2) faces the center of the seed-taking plate. One side plate surface of the slot hole (21) is provided with a slope surface (22), and the slope surface (22) inclines towards the slot hole (21). The other side plate surface is provided with a release plate placement groove (6). The plane of the seed-taking cavity (2) and the release plate placement groove (6) form a seed-taking space.

[0068] The slope surface (22) inclining towards the notch means that the end far from the notch is thicker, and the end close to the notch is thinner.

[0069] During actual seed taking operation: It is also necessary to be able to place the release plate (7) in the release plate placement groove (6). The seed taking cavity (2) and the release plate (7) form a seed taking space. The release plate (7) is hinged to the seed taking plate. The release plate (7) can swing in the release plate placement groove (6), and the swinging state realizes covering the seed taking cavity (2) and exposing the seed taking cavity (2). Covering the seed taking cavity (2) is the seed taking state, and exposing the seed taking cavity (2) is the seed discharging state.

[0070] In this embodiment, the seed taking plate is an integral body, and the slot holes are through holes on both sides of the measuring cylinder plate body.

[0071] The seed taking plate is arranged vertically. The seed chamber is arranged on one side of the seed taking plate, and the seed discharging box (18) is arranged on the other side, realizing seed taking on one side of the seed taking plate and seed discharging on the other side.

The seed taking block (1) is connected to the outer edge notch of the seed taking disc (5), and the seed taking block (1) and the seed taking disc (5) form a slot hole (21).

[0073] Since the seed taking block (1) and the seed taking disc (5) are separately designed, in order to adapt to different crops, only the seed taking block (1) needs to be replaced. The shapes of the seed taking cavities (2) on different seed taking blocks (1) are different and can adapt to different crops, such as designing seed taking blocks (1) suitable for sowing bottle gourds, Mongolian watermelons, and sunflower seeds.

[0074] Embodiment 9: Compared with Embodiment 7, the difference in this embodiment is that the seed taking block (1) is connected to the seed taking disc (5) by bolts or screws, and the seed taking disc (5) and the seed taking block (1) are in the same plane.
