Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting equipment technology, specifically a rice seed soaking and flotation impurity removal mechanism. Background Technology
[0002] In rice cultivation, seed soaking, as a crucial pretreatment step, acts like a "preheating program" to begin the seed's life journey, directly impacting subsequent germination quality and seedling growth. Furthermore, the impurity removal process before soaking is the "first line of defense" to ensure seed quality, its importance being self-evident—high-quality seeds significantly improve germination rates, resulting in stronger seedlings and laying a solid foundation for a bountiful rice harvest.
[0003] Currently, traditional methods for soaking and removing impurities from rice seeds still rely primarily on manual labor. This method typically involves placing rice seeds in clean water, where empty, shriveled seeds and impurities, being less dense than plump seeds, float. After flotation, the floating particles are manually removed one by one. However, this method is extremely labor-intensive, especially in large-scale planting scenarios. Operators must repeatedly bend over to retrieve the seeds for extended periods, resulting in significant physical exhaustion. Furthermore, it is extremely inefficient, with manual operation being far slower than mechanized equipment, making it difficult to meet the demands of modern agriculture for large-scale seed processing.
[0004] In view of this, we propose a rice seed soaking and flotation impurity removal mechanism. Utility Model Content

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] A rice seed soaking and flotation impurity removal mechanism includes a soaking tank 1, an internal stirring mechanism, a fixed plate 5 fixedly connected to the outer circumference of the soaking tank 1, a hydraulic cylinder 50 fixedly mounted at the bottom of the fixed plate 5, a connecting rod 6 fixedly mounted on the piston rod of the hydraulic cylinder 50, a vertically movable suction hood 2 above the soaking tank 1, an exhaust pipe 4 connected to the top of the suction hood 2, and the connecting rod 6 fixedly connected to the outer wall of the exhaust pipe 4. A collection assembly 3 is installed at the end of the exhaust pipe 4 away from the suction hood 2, the collection assembly 3 including a collection cylinder 30 connected to the exhaust pipe 4, and a detachable mesh box 35 installed inside the collection cylinder 30. By setting a stirring mechanism inside the soaking tank 1, the rice seeds can be fully tumbled during the soaking process, promoting the separation of seeds from impurities. At the same time, the exhaust pipe 4 and the collection assembly 3 are used to suck impurities floating on the water surface into the mesh box 35 inside the collection cylinder 30 through the suction hood 2, realizing the automatic collection of impurities.
[0026] In a preferred embodiment, a discharge port 14 is provided on the outer circumference of the soaking tank 1 near the bottom, and a sealing plate 10 is installed at the discharge port 14. The sealing plate 10 is fixedly connected to the outer wall of the soaking tank 1 by two symmetrically arranged fixing bolts 11. The discharge port 14 and the sealing plate 10 facilitate the discharge of seeds after impurity removal and soaking, and the fixing bolts 11 ensure the sealing performance between the sealing plate 10 and the soaking tank 1 to prevent liquid leakage.
[0027] In a preferred embodiment, the stirring mechanism includes a stirring shaft 16 rotatably mounted at the center of the bottom of the soaking tank 1. The outer circumference of the stirring shaft 16 is integrally formed with several stirring blades 15. A stirring motor 13, with its output shaft coaxially fixed to the stirring shaft 16, is mounted at the bottom of the soaking tank 1. The stirring motor 13 drives the stirring shaft 16 and the stirring blades 15 to rotate, forming a stable water flow that allows the seeds to tumble evenly within the soaking tank 1, enhancing the separation of impurities from the seeds and ensuring the uniformity of soaking and impurity removal.
[0028] In this preferred embodiment, when the suction hood 2 descends into the soaking tank 1, the outer circumference of the suction hood 2 is tightly fitted with the inner ring wall of the soaking tube. This prevents air leakage during suction, improves suction efficiency, and ensures that impurities are fully sucked into the collection assembly 3.
[0029] In a preferred embodiment, a mounting cover 31 is threaded onto the top of the collecting cylinder 30. The top of the mounting cover 31 communicates with the suction pipe 4. A connecting pipe 33 is installed on the outer wall of the mounting cover 31, and a suction pump 32 is installed on the connecting pipe 33. The suction pump 32 provides suction power to the suction pipe 4 through the connecting pipe 33 and the mounting cover 31. The threaded collecting cylinder 30 is easy to disassemble and maintain, and also facilitates cleaning of the collecting cylinder 30 and the mesh box 35. It should be added that a mounting ring 310 is integrally formed coaxially at the bottom of the mounting cover 31, and the inner ring wall of the collecting cylinder 30 is threadedly connected to the outer ring wall of the mounting ring 310.
[0030] In a preferred embodiment, a filter screen 34 is fixedly installed inside the mounting cover 31 at the opening of the connecting pipe 33, and two support blocks 36 are symmetrically fixedly installed inside the collection cylinder 30, with the bottom of the mesh box 35 contacting the top of the support blocks 36. The filter screen 34 prevents larger impurities from entering the vacuum pump 32, avoiding equipment blockage. The support blocks 36 support the mesh box 35, ensuring its stable installation inside the collection cylinder 30, facilitating the collection and cleaning of impurities.
[0031] As a preferred embodiment, a drain pipe 37 is installed at the bottom of the collection cylinder 30, and a drain valve 38 is installed on the drain pipe 37. The drain pipe 37 and the drain valve 38 can drain the wastewater in the collection cylinder 30, which facilitates subsequent treatment and keeps the collection component 3 clean.
[0032] In a preferred embodiment, the bottom of the soaking tank 1 is fixedly equipped with a plurality of support legs 12 arranged in a circular array. The support legs 12 enable the soaking tank 1 to be placed stably on the ground, ensuring the stability of the equipment during operation.
[0033] In use, the rice seed soaking and flotation impurity removal mechanism of this utility model first pours rice seeds and water into the soaking tank 1, and starts the stirring motor 13. The stirring motor 13 drives the stirring shaft 16 and stirring blades 15 to rotate, forming a stable water flow, which makes the seeds roll evenly in the soaking tank 1, promoting the separation of seeds from impurities. Empty and shriveled seeds and impurities float on the water surface due to their low density. Next, the hydraulic cylinder 50 is started. The hydraulic cylinder 50 drives the suction hood 2 to descend into the soaking tank 1 through the connecting rod 6. The outer circumference of the suction hood 2 is tightly fitted with the inner ring wall of the soaking tank 1 to prevent air leakage during suction. Then, the suction pump 32 is turned on. The suction pump 32 generates suction in the suction pipe 4 through the connecting pipe 33 and the mounting cover 31. Impurities floating on the water surface are sucked into the suction pipe 4 through the suction hood 2 and then enter the mesh box 35 in the collection cylinder 30 for impurity collection. During the collection process, the filter screen 34 in the mounting cover 31 can prevent larger impurities from entering the suction pump 32 and avoid equipment blockage. After impurity removal is completed, turn off the vacuum pump 32 and hydraulic cylinder 50, causing the suction hood 2 to rise and return to its original position. When it is necessary to discharge the seeds, unscrew the fixing bolt 11, open the sealing plate 10, and discharge the seeds through the discharge port 14.
