Description

Technical Field

[0001] This utility model relates to the field of rice planting equipment technology, specifically to a rice transplanter seedling separating device for preventing blockage. Background Technology

[0002] In mechanized rice planting, the rice transplanter's seedling separating device is a core component that ensures transplanting efficiency and quality. However, many problems in its practical application have been troubling farmers and agricultural production.

[0003] Existing seedling separating devices have significant deficiencies in their anti-clogging performance. Traditional seedling separating devices have a simple separating channel design and lack an effective dynamic pushing mechanism. Once seedlings enter the channel, they cannot be continuously pushed by their own structure, easily leading to seedling accumulation and stagnation. Moreover, the slow throughput of a single channel affects the efficiency of seedling separation and increases the risk of clogging. In severe cases, it can even directly block the separating channel, causing the entire separating process to be interrupted, greatly reducing the continuity and efficiency of rice transplanting operations.

[0004] In view of this, we propose a rice transplanter seedling separation device to prevent clogging. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rice transplanter seedling separating device to prevent clogging.

[0006] The technical solution of this utility model is:

[0007] A rice transplanter seedling separating device for preventing blockage includes a separating plate with several mounting plates fixedly installed inside. A separating channel is provided between each pair of adjacent mounting plates. Each separating channel has a actuating component installed on both sides. The actuating component includes a fixed plate fixed to the mounting plate, two belt shafts symmetrically rotatably mounted on the fixed plate, and a belt body installed between the two belt shafts. Several actuating plates are fixedly installed on the outer ring wall of the belt body. A actuating motor is fixedly installed at the bottom of the fixed plate, and the actuating motor is coaxially fixed with one of the belt shafts. By setting multiple separating channels within the separating plate and equipping each channel with an actuating component consisting of a fixed plate, belt shafts, belt body, and actuating plates, the actuating motor drives the belt shafts to rotate the belt body, causing the actuating plates to continuously and dynamically move the seedlings within the channel. This design effectively prevents seedlings from accumulating and stagnating in the channels, ensuring smooth seedling transport through active pushing, fundamentally reducing blockage problems caused by seedling congestion. Simultaneously, the multiple independent channels also reduce the probability of blockage caused by excessive load on a single channel.

[0008] As a preferred technical solution, four vertical plates are fixedly installed on the top of the seedling separating plate, and a horizontal plate is fixedly installed on the top of each vertical plate. A fixing bolt is installed at each of the four corners of each horizontal plate. The combination structure of the four vertical plates and the horizontal plates not only provides a stable installation foundation for the seedling separating plate, but also achieves a firm connection between the seedling separating device and the main body of the rice transplanter through the fixing bolts at the four corners of the horizontal plates.

[0009] As a preferred technical solution, the length of the vertical plate on the left side of the seedling separating board is shorter than the length of the vertical plate in the middle of the seedling separating board, and the tops of the four vertical plates are flush. This arrangement allows the seedling separating board to be tilted downwards from left to right, enabling the seedlings to move from left to right under the influence of gravity.

[0010] As a preferred technical solution, the seedling separating plate has two guide blocks symmetrically fixedly connected to the left side of the seedling separating channel, with adjacent guide blocks being integrally formed. This can pre-regulate and guide the seedlings entering the seedling separating channel. The arc-shaped transition design of the guide blocks can prevent seedlings from bending or piling up due to collisions at the entrance, allowing the seedlings to enter the seedling separating channel in a more orderly manner.

[0011] As a preferred technical solution, the paddle includes a main body fixedly connected to the belt body, and a protective pad is fixedly installed on the outer side of the main body. The main body of the paddle ensures the structural strength when paddles the seedlings, while the outer protective pad can buffer the contact between the paddle and the seedlings, avoiding damage to the seedlings from hard contact.

[0012] As a preferred technical solution, the paddles on two adjacent actuating components are staggered. By staggering the paddles of adjacent actuating components, the actuating forces on both sides of the seedling separating channel are staggered in time and space.

[0013] As a preferred technical solution, the height of the mounting plate is less than the height of the guide block, and the top of the paddle is flush with the top of the guide block. This ensures a seamless connection between the paddle's actuation range and the guide block's guidance range. When seedlings pass through the guide block and enter the seedling separation channel, the paddle immediately applies a paddle force, preventing seedlings from briefly lingering in the transition area. Simultaneously, it ensures that the paddle's actuation height matches the seedling transport path, maximizing the actuation effect and reducing blockages caused by insufficient actuation.

[0014] As a preferred technical solution, the actuating motor is fixed to the bottom of the seedling separating plate, and a transmission shaft is coaxially fixed to the output shaft of the actuating motor. The transmission shaft passes through the seedling separating plate and the mounting plate and is coaxially fixed to the belt shaft. This transmission structure keeps the motor away from the seedlings and soil in the seedling separating channel, reducing the risk of the motor being contaminated by soil or entangled by seedlings, and ensuring the stable operation of the drive components.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features multiple seedling separating channels within a seedling separating plate, with each channel equipped on both sides by a prying assembly consisting of a fixed plate, a belt shaft, a belt body, and pry plates. A prying motor drives the belt shaft to rotate the belt body, causing the pry plates to continuously and dynamically move the seedlings within the channel. This design effectively prevents seedlings from accumulating and stagnating within the channels, ensuring smooth seedling transport through active pushing and fundamentally reducing blockages caused by seedling congestion. Furthermore, the multiple independent channels reduce the probability of blockages caused by excessive load on a single channel. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] The anti-clogging rice transplanter seedling separating device includes a separating plate 1, with several mounting plates 11 fixedly installed inside the separating plate 1. A separating channel is provided between each pair of adjacent mounting plates 11. A toggle assembly 4 is installed on both sides of each separating channel. The toggle assembly 4 includes a fixed plate 43 fixed to the mounting plate 11. Two belt shafts 40 are symmetrically rotatably mounted on the fixed plate 43. A belt body 41 is installed between the two belt shafts 40. Several paddles 42 are fixedly installed on the outer ring wall of the belt body 41. A toggle motor 3 is fixedly installed at the bottom of the fixed plate 43, and the toggle motor 3 is coaxially fixed with one of the belt shafts 40. By setting multiple separating channels within the separating plate 1 and equipping each channel with a toggle assembly 4 consisting of a fixed plate 43, belt shafts 40, belt body 41, and paddles 42, the toggle motor 3 drives the belt shafts 40 to rotate the belt body 41, causing the paddles 42 to continuously and dynamically move the seedlings within the channel. This design effectively prevents seedlings from piling up and stagnating in the channels. By actively pushing the seedlings, it ensures smooth seedling transport and fundamentally reduces blockage problems caused by seedling congestion. At the same time, the setting of multiple independent channels also reduces the probability of blockage caused by excessive load on a single channel.

[0026] In a preferred embodiment, four vertical plates 2 are fixedly installed on the top of the seedling separating plate 1, and a horizontal plate 20 is fixedly installed on the top of each vertical plate 2. A fixing bolt 21 is installed at each of the four corners of each horizontal plate 20. The combination structure of the four vertical plates 2 and the horizontal plates 20 not only provides a stable installation foundation for the seedling separating plate 1, but also achieves a firm connection between the seedling separating device and the main body of the rice transplanter through the fixing bolts 21 at the four corners of the horizontal plates 20.

[0027] In a preferred embodiment, the length of the vertical plate 2 located on the left side of the seedling separating board 1 is shorter than the length of the vertical plate 2 in the middle of the seedling separating board 1, and the tops of the four vertical plates 2 are flush. This arrangement allows the seedling separating board 1 to be tilted downwards from left to right, enabling the seedlings to move from left to right under the influence of gravity.

[0028] In a preferred embodiment, two guide blocks 10 are symmetrically fixedly connected inside the seedling separating plate 1 on the left side of the seedling separating channel, with adjacent guide blocks 10 integrally formed. This can pre-regulate and guide the seedlings entering the seedling separating channel. The arc-shaped transition design of the guide blocks 10 can prevent the seedlings from bending or piling up due to collisions at the entrance, allowing the seedlings to enter the seedling separating channel in a more orderly manner.

[0029] In a preferred embodiment, the paddle 42 includes a main body 420 fixedly connected to the belt body 41, and a protective pad 421 is fixedly installed on the outer side of the main body 420. The main body 420 of the paddle 42 ensures the structural strength when paddles the seedlings, while the outer protective pad 421 can buffer the contact between the paddle 42 and the seedlings, avoiding damage to the seedlings from hard contact.

[0030] As a preferred embodiment, the paddles 42 on two adjacent actuating components 4 are staggered. By staggering the paddles 42 on adjacent actuating components 4, the actuating forces on both sides of the seedling separating channel are staggered in time and space.

[0031] In this preferred embodiment, the height of the mounting plate 11 is less than the height of the guide block 10, and the top of the paddle 42 is flush with the top of the guide block 10. This ensures a seamless connection between the paddle 42's actuation range and the guide block 10's guidance range. When seedlings pass through the guide block 10 and enter the seedling separation channel, the paddle 42 can immediately apply a paddle force to them, preventing seedlings from briefly lingering in the transition area. Simultaneously, it ensures that the paddle 42's actuation height matches the seedling transport path, maximizing the actuation effect and reducing blockages caused by inadequate actuation.

[0032] In a preferred embodiment, the actuating motor 3 is fixed to the bottom of the seedling separating plate 1, and a transmission shaft is coaxially fixed to the output shaft of the actuating motor 3. The transmission shaft passes through the seedling separating plate 1 and the mounting plate 11 and is coaxially fixed to the belt shaft 40. This transmission structure keeps the motor away from the seedlings and soil in the seedling separating channel, reducing the risk of the motor being contaminated by soil or entangled by seedlings, and ensuring the stable operation of the drive components.

[0033] When using the anti-clogging rice transplanter seedling separating device of this utility model, the four vertical plates 2 at the top of the separating plate 1 and the horizontal plate 20 are combined to achieve a stable connection with the main body of the transplanter through the fixing bolts 21 at the four corners of the horizontal plate 20, ensuring the stability of the device during operation. Since the left vertical plate 2 of the separating plate 1 is shorter than the middle vertical plate 2 and its top is flush, the separating plate 1 is tilted with the left side higher than the right side, providing basic power for the seedlings to move from left to right under the action of gravity.

[0034] Once the seedlings enter the separating channel under the action of the guide block 10, the actuating components 4 on both sides of the channel begin to operate. The actuating motor 3 is fixed to the bottom of the separating plate 1 and is coaxially connected to the belt shaft 40 through the transmission shaft passing through the separating plate 1 and the mounting plate 11, driving the belt shaft 40 to rotate, which in turn drives the belt body 41 to rotate. The actuating plates 42 on the outer ring wall of the belt body 41 move synchronously with the belt. Because the actuating plates 42 of adjacent actuating components 4 are staggered, the actuating forces on both sides of the channel are staggered in time and space, acting comprehensively on the seedlings and avoiding blind spots in actuation.

[0035] Under the combined action of the inclined seedling separating plate 1, the guide block 10, and the dynamic pushing of the paddle 42, the seedlings move continuously to the right along the seedling separating channel. Multiple independent seedling separating channels disperse the seedling load, effectively avoiding congestion and accumulation, and ultimately achieving smooth seedling separation, significantly reducing the probability of blockage and ensuring efficient rice transplanting.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
