Description

Technical Field

[0001] This utility model belongs to the field of sowing technology, and specifically relates to a sowing machine. Background Technology

[0002] The handheld spreader seeder uses an internal feeding mechanism and a high-speed rotating seeding disc to evenly spread seeds into the field.

[0003] Existing handheld seeders require operators to hold the handle for seeding and adjust the seeding speed by rotating the seeding disc, thereby adjusting the seeding width. This method of adjustment is greatly affected by external wind. When reducing the initial seeding speed to decrease the seeding width, the impact of wind on the seeds thrown at low speed will be further amplified. When sowing small and lightweight seeds such as celery, the uniformity of seeding is poor. Utility Model Content

[0004] This invention provides a seed-spreading machine that can tilt and spread seeds downwards at different angles, thereby improving the wind resistance of the seeds during seed spreading.

[0005] This utility model provides the following technical solution: a spraying seeder, including a spraying seeder body, a conical guide plate fixedly connected to one side of the spraying seeder body, a semi-ring handle fixedly connected to the inner wall of the spraying seeder body and the conical guide plate, a finger grip block slidably connected to the bottom end of the semi-ring handle, and the finger grip block can be locked to the side wall of the semi-ring handle by a locking mechanism.

[0006] The semi-ring handle has a relief groove at its center, and the width of the relief groove is smaller than the width of the finger grip block.

[0007] The outer wall of the semi-ring handle is fixedly connected with a reference scale, which corresponds to the position of the clearance groove.

[0008] A friction pad is fixedly connected to the outer wall of the semi-ring handle.

[0009] The finger grip block has a limiting sleeve fixedly connected to its top end, and the limiting sleeve is fitted onto the outer wall of the semi-ring handle.

[0010] A protective ring is fixedly connected to the bottom end of the grip block.

[0011] The locking mechanism includes an adjustment knob, a threaded rod, and a friction positioning block. The threaded rod is threaded to the bottom end of the adjustment knob, passes through the relief groove, and is fixedly connected to the grip block. The friction positioning block is fixedly connected to the bottom end of the adjustment knob.

[0012] The beneficial effects of this utility model are: 1. The semi-circular handle with its large-span arc shape allows for multi-angle and multi-position gripping, enabling adjustments to the spray nozzles of the spreader body. This provides a basis for tilting and spreading seeds at different angles, allowing the spreader body to tilt downwards to spread seeds. While adjusting the spreading width, this does not require reducing the seed spreading speed and can apply an initial falling speed to the seeds, effectively reducing seed fall time and improving wind resistance when spreading small seeds.

[0013] 2. The adjustment of the grip block along the semi-circular handle trajectory adapts to different angles of personnel holding the semi-circular handle, allowing personnel to keep their fingers horizontal and wrists vertical when holding it, enabling them to hold the device in a more comfortable way, making it more comfortable during long-term holding and throwing processes.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0017] Please see Figures 1-4 The present invention provides the following technical solution: a spreading seeder, including a spreading seeder body 1, a conical guide plate 11 fixedly connected to one side of the spreading seeder body 1, a semi-ring handle 2 fixedly connected to the inner wall of the spreading seeder body 1 and the conical guide plate 11, a finger grip block 3 slidably connected to the bottom end of the semi-ring handle 2, and the finger grip block 3 can be locked to the side wall of the semi-ring handle 2 by a locking mechanism 4.

[0018] In this implementation plan: When it is necessary to reduce the seed spreading width, the operator adjusts the locking mechanism 4 to release the lock on the finger grip block 3, adjusts the finger grip block 3 to rotate clockwise at a suitable angle along the path of the semi-circular handle 2, and then uses the locking mechanism 4 to lock the finger grip block 3 again. The operator still holds the finger grip block 3 with their fingers, and their hand is holding the part of the semi-circular handle 2 corresponding to the adjusted finger grip block 3. At this time, the seeder body 1 is in an inclined state. After the seeds are spread out by the impeller of the seeder body 1, the initial direction of the seed movement is inclined downward, and the initial velocity is decomposed into a horizontal initial velocity and a downward initial velocity. In addition to the seeds falling naturally under the influence of gravity, the initial downward velocity accelerates the downward fall of the seeds, reducing the time the seeds spend falling in the air and thus reducing the flight distance of the seeds. This achieves the purpose of reducing the seed scattering width. Furthermore, the reduction in the falling time means that the seeds are subjected to wind force in the air for a shorter period of time, which can reduce the influence of external wind force on the seed falling trajectory and improve the uniformity of seed scattering and sowing. The flared and tilted opening of the seed scattering machine body 1 can guide the seeds contained inside, so that the seeds can gather at the bottom in the tilted state. When adjusting the scattering width, it can be adjusted again according to the adjusted scattering width.

[0019] The large-span arc-shaped support of the semi-ring handle 2 allows for multi-angle and multi-position gripping, enabling adjustments to the spray nozzle of the seeder body 1 at different angles. This provides the basis for tilting and spraying seeds at different angles. The finger grip block 3 adjusts along the trajectory of the semi-ring handle 2 to accommodate different angles of gripping, allowing the user to keep their fingers horizontal and wrist vertical, reducing wrist strain and providing a more comfortable gripping experience, especially during extended spraying sessions.

[0020] The semi-ring handle 2 has a relief groove 21 in the center, and the width of the relief groove 21 is smaller than the width of the finger grip block 3. By setting the relief groove 21, the threaded rod 42 can be made to make way, so that the threaded rod 42 can pass through the semi-ring handle 2 and connect with the finger grip block 3.

[0021] The outer wall of the semi-ring handle 2 is fixedly connected with a reference scale 22, which corresponds to the position of the clearance groove 21. By setting the reference scale 22, it can serve as a reference. When the personnel adjust to the appropriate throwing width, by remembering the corresponding reference scale 22, the finger grip block 3 can be directly adjusted to the corresponding scale when needed next time. Moreover, during the adjustment process, if the effect is not good after the first adjustment and a second adjustment is required, the reference scale 22 can provide a more intuitive reference.

[0022] A friction pad 23 is fixedly connected to the outer wall of the semi-ring handle 2; by setting the friction pad 23, the roughness of the top of the semi-ring handle 2 can be increased, and it can provide greater locking resistance after contacting the friction positioning block 43.

[0023] A limiting sleeve 31 is fixedly connected to the top of the finger grip block 3. The limiting sleeve 31 is sleeved on the outer wall of the semi-ring handle 2. By setting the limiting sleeve 31, the finger grip block 3 can be limited to prevent the finger grip block 3 from twisting around the threaded rod 42.

[0024] A protective ring 32 is fixedly connected to the bottom of the grip block 3; by setting the protective ring 32, the relative slippage between the user's fingers and the grip block 3 can be restricted, making the grip of the semi-ring handle 2 and the grip block 3 more stable and comfortable.

[0025] The locking mechanism 4 includes an adjustment knob 41, a threaded rod 42, and a friction positioning block 43. The threaded rod 42 is threaded to the bottom end of the adjustment knob 41 and passes through the relief groove 21 to be fixedly connected to the grip block 3. The friction positioning block 43 is fixedly connected to the bottom end of the adjustment knob 41. After the grip block 3 is adjusted to a suitable position, the adjustment knob 41 and the threaded rod 42 rotate relative to each other, causing the friction positioning block 43 to move toward the friction pad 23 until the friction positioning block 43 is tightly attached to the surface of the friction pad 23. The friction between the friction positioning block 43 and the friction pad 23 restricts the relative sliding of the grip block 3 and the semi-circular handle 2.

[0026] The working principle and usage process of this utility model: A person holds the semi-ring handle 2 and the finger grip block 3 to horizontally lift the main body 1 of the seeder. Seeds are thrown out in a thick, fan-shaped distribution under the action of the feeding impeller inside the main body 1. At this time, the seed throwing width is the maximum throwing width. When it is necessary to reduce the seed throwing width, the person adjusts the locking mechanism 4 to release the lock on the finger grip block 3, and adjusts the finger grip block 3 to rotate clockwise at a suitable angle along the path of the semi-ring handle 2. Then, the locking mechanism 4 is used again to lock the finger grip block 3, while the person maintains the state of holding the finger grip block 3 with their fingers. The hand is held in the semi-ring corresponding position after the adjustment of the finger grip block 3. With the handle 2 in place, the main body 1 of the seeder is tilted. After the seeds are thrown out by the impeller, the initial direction of the seeds' movement is tilted downwards. The initial velocity is decomposed into a horizontal initial velocity and a downward initial velocity. In addition to the seeds falling naturally under the action of gravity, the downward initial velocity will accelerate the seeds' descent, reduce the time the seeds spend falling in the air, and thus reduce the flight distance of the seeds. This achieves the purpose of reducing the seed throwing width. Furthermore, the reduction in the falling time reduces the time the seeds are affected by wind in the air, which can reduce the influence of external wind on the seed's falling trajectory and improve the uniformity of seed throwing and sowing.
