Description

Technical Field

[0001] The utility model relates to the technical field of corn seeders, and more specifically to a small corn seeder. Background Art

[0002] A corn manual seeder is a simple tool used by small farms or farmers to plant corn. It usually consists of some basic parts, allowing growers to plant corn seeds more efficiently without relying on expensive mechanical equipment. There are many types of manual seeders, including roller seeders, vibrating seeders, and handheld seeders. Among them, handheld seeders are usually smaller and can be held by growers and sown directly in the soil. They are suitable for smaller areas or scenes that require delicate operations.

[0003] The existing handheld seeder includes a sowing barrel and a pull rod arranged thereon. When sowing, the user needs to hold the handle tightly, and the pull rod drives the outlet at the bottom to open, and the seeds fall from the sowing barrel into the soil. The above mechanism requires the user to hold the handle tightly every time sowing, which is labor-intensive and laborious. Therefore, it is necessary to improve the handheld seeder to make it more labor-saving and easy to operate. Utility Model Content

[0006] The discharging mechanism includes a lifting member, a force-bearing plate in contact with the lifting member, and a reset member connected to the force-bearing plate. An opening is provided on one side of the main cylinder body. The force-bearing plate extends into the main cylinder body through the opening and is provided corresponding to the rotating plate.

[0007] In a preferred embodiment, the lifting member includes a push rod, a top plate arranged on the top of the push rod, a limit block arranged in the middle of the push rod, a reset spring 1 mounted on the push rod and a limit cylinder arranged outside the reset spring 1, the limit cylinder is fixed on the sowing cylinder, the push rod is passed through the limit cylinder, and the limit block is against the bottom wall of the limit cylinder.

[0008] In a preferred embodiment, the bottom of the top rod is arranged in an arc shape, and the top plate is arranged horizontally.

[0010] In a preferred embodiment, the bending portion includes two symmetrically arranged bending rods.

[0011] In a preferred embodiment, the reset member includes a second reset spring disposed at the bottom of the horizontal portion, one end of the second reset spring is connected to the horizontal portion, and the other end is connected to the main cylinder.

[0012] In a preferred embodiment, the bottom of the main cylinder is configured to be wedge-shaped.

[0013] The beneficial effects of the technical solution of the utility model are:

[0014] This solution does not require the operator to hold the handle tightly to open the bottom opening of the main cylinder through the pull rod. When inserted into the soil, under the reaction force of the soil, the lifting piece directly lifts the force plate to rotate it, and then pushes the rotating plate outward to open the bottom opening of the main cylinder.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0020] like Figure 1-3 As shown, the technical solution of the utility model provides a small corn seeder, including a sowing barrel 1, a handle 15 arranged above the sowing barrel 1 and a discharging mechanism arranged below the sowing barrel 1, wherein the sowing barrel 1 includes a main barrel body 2 and a rotating plate 3 arranged on the main barrel body 2, and the rotating plate 3 is connected to the main barrel body 2. The discharging mechanism includes a lifting member 4, a force plate 10 in contact with the lifting member 4 and a reset member connected to the force plate 10, an opening is arranged on one side of the main barrel body 2, and the force plate 10 extends into the main barrel body 2 through the opening and is arranged corresponding to the rotating plate 3.

[0021] During sowing, the operator holds the handle 15 and then inserts the sowing tube 1 into the soil. During insertion, the lifting member 4 is forced to push upward, thereby driving the force-bearing plate 10 to rotate. When the force-bearing plate 10 rotates, the rotating plate 3 opposite to it is pushed outward, so that the bottom channel of the main cylinder 2 is opened, and then the corn seeds fall into the soil. This method does not require the operator to hold the handle 15 tightly to open the bottom opening of the main cylinder 2 through the pull rod. When inserted into the soil, under the reaction force of the soil, the lifting member 4 directly lifts the force-bearing plate 10 to rotate it, and then pushes the rotating plate 3 outward to open the bottom opening of the main cylinder 2. After the main cylinder 2 is pulled out, the lifting member 4 is reset, and the force-bearing plate 10 and the rotating plate 3 are automatically reset. A reset structure such as a torsion spring can be set at the connection between the rotating plate 3 and the main cylinder 2 to achieve its automatic reset. The planting process is more labor-saving and easy to operate.

[0022] The lifting member 4 includes a push rod 5, a top plate 6 arranged on the top of the push rod 5, a limit block 7 arranged in the middle of the push rod 5, a return spring 8 sleeved on the push rod 5, and a limit cylinder 9 arranged outside the return spring 8, the limit cylinder 9 is fixed on the sowing cylinder 1, the push rod 5 is arranged through the limit cylinder 9, and the limit block 7 is against the bottom wall of the limit cylinder 9. The bottom of the push rod 5 is arranged in an arc shape, and the top plate 6 is arranged horizontally.

[0023] In the above scheme, when inserting into the soil, the bottom of the push rod 5 first contacts the soil, and after the push rod 5 is inserted into the soil, the limit block 7 on the push rod 5 squeezes the return spring 8, and then the main cylinder 2 moves downward compared to the push rod 5 and is inserted into the soil. At this time, the push rod 5 on the push rod 5 limits the force plate 10, and the force plate 10 rotates based on the connection with the main cylinder 2. The bottom of the main cylinder 2 is an arc, which is convenient for insertion into the soil.

[0024] The force-bearing plate 10 is rotatably connected to the main cylinder 2, and includes a horizontal portion 11 and a bending portion 12 extending into the main cylinder 2, and the bottom end of the bending portion 12 faces the rotating plate 3. The top plate 6 contacts the horizontal portion 11, and the horizontal portion 11 is the force-bearing position. The entire force-bearing plate 10 rotates clockwise after being stressed, and then pushes the rotating plate 3 outward, the opening is opened, and the seeds fall. The bending portion 12 includes two symmetrically arranged bending rods 13, and the bending rod 13 structure is adopted to avoid affecting the falling of seeds.

[0025] The reset member includes a reset spring 14 disposed at the bottom of the horizontal portion 11, one end of the reset spring 14 is connected to the horizontal portion 11, and the other end is connected to the main cylinder 2. After the main cylinder 2 is pulled out of the soil, the top rod 5 is reset, the force plate 10 is reset, and the rotating plate 3 is also reset, and the next sowing is continued.

[0026] The bottom of the main cylinder 2 is configured to be wedge-shaped, so as to facilitate insertion into the soil.

[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
