Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, and in particular to a cucumber seed screening and filtering device. Background Technology

[0002] Cucumber seeds are the mature seeds of cucumbers, belonging to the Cucurbitaceae family. They are the basis for cucumber propagation and cultivation. They are usually flat and oval, with a smooth or slightly textured surface, and are mostly white, light yellow, or brownish-yellow in color.

[0003] However, the current cucumber seed screening process generally uses the traditional soaking and filtration method. Conventional soaking and filtration equipment lacks an effective seed dispersion mechanism, which causes cucumber seeds to easily accumulate and sink to the bottom during soaking. This not only makes it difficult to effectively separate plump seeds from empty and shriveled seeds, but also often results in seeds sticking together. At the same time, most existing equipment uses a single filter screen structure, which cannot simultaneously achieve the dual functions of lifting seeds that sink to the bottom and retrieving seeds that float to the surface. Operators need to repeatedly perform multiple retrieval and stirring operations, which increases labor intensity and reduces screening efficiency. In view of this, a cucumber seed screening and filtration device is provided to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cucumber seed screening and filtering device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cucumber seed screening and filtering device, comprising a filter box, wherein hydraulic rods are fixedly connected to the top left and right sides of the filter box, a connecting plate is fixedly connected to the output end of the hydraulic rods, a mesh is fixedly connected to the end of the connecting plate away from the hydraulic rods, a drive motor is fixedly connected to the middle of the left side of the bottom of the filter box, and a linkage shaft is rotatably connected to the middle of the lower right side inside the filter box.

[0006] As a further description of the above technical solution: a transmission belt is provided between the output end of the drive motor and the linkage shaft; stirring blades are fixedly connected to the top of both the output end of the drive motor and the linkage shaft; a front hollow shell is fixedly connected to the top of the front end face of the filter box; a rear hollow shell is fixedly connected to the top of the rear end face of the filter box; a stepper motor is fixedly connected to the right end face of the front hollow shell; a threaded rod is fixedly connected to the output end of the stepper motor; a moving block is helically connected to the outer side of the threaded rod; a limit rod is fixedly connected inside the rear hollow shell; a slider is slidably connected to the outer side of the limit rod; sliding seats are fixedly connected to the top of both the moving block and the slider; a reduction motor is fixedly connected above the sliding seat on the top of the moving block; a central shaft is fixedly connected to the output end of the reduction motor; the central... The end of the shaft away from the geared motor is rotatably connected to the front end face of the sliding seat at the top of the slider. A flat plate is fixedly connected to the top of the central shaft, and a screen is fixedly connected to the bottom of the central shaft. The inner wall of the filter box is slidably connected to the edge of the screen. The inner wall of the front hollow shell is in contact with the surface of the moving block, and the inner wall of the rear hollow shell is disconnected from the surface of the slider. The tops of both the front and rear hollow shells are slidably connected to the bottom of the sliding seat. The hydraulic rod drives the screen in the filter box to slide up and down to support the cucumber seeds soaked in water, preventing the cucumber seeds that sink to the bottom from falling to the bottom of the filter box. The stepper motor drives the screen located at the top of the filter box to move left and right in a circular motion above the inner side of the filter box, which facilitates the screen to quickly scoop up empty and shriveled seeds floating on the water surface, improving the efficiency of cucumber seed soaking and screening.

[0007] As a further description of the above technical solution: the longitudinal cross-section of the connecting plate is L-shaped, and the maximum extension length of the hydraulic rod is the same as half of the internal depth of the filter box, which allows the hydraulic rod to drive the partition net in the filter box to move up and down through the connecting plate, making it convenient to retrieve and soak cucumber seeds.

[0008] As a further description of the above technical solution: the liquid in the filter box is a 5% salt solution, and the level of the salt solution is aligned with the middle of the screen located on the upper inner side of the filter box. There are two sets of stirring blades, and the stirring blades are distributed on the left and right sides of the lower middle inside the filter box. The 5% salt solution can enhance the buoyancy difference and improve the accuracy of cucumber seed soaking and screening.

[0009] As a further description of the above technical solution: a connecting rod is fixedly connected between the moving block and the sliding seat on its top, and between the slider and the sliding seat on its top. A sliding groove from left to right is opened in the middle of the top of the front hollow shell and the rear hollow shell, and the width of the sliding groove matches the cross-sectional diameter of the connecting rod. The sliding seat on the outer side of the front hollow shell can be moved synchronously through the moving block inside the front hollow shell.

[0010] As a further description of the above technical solution: the moving block has a through hole from left to right inside, and the inner wall of the through hole is provided with an internal thread that matches the pitch and helical direction of the threaded rod surface. The stepper motor can drive the threaded rod to rotate forward and reverse. The rotation provided by the stepper motor allows the threaded rod to drive the moving block on its outer side to move left and right inside the front hollow shell when it rotates.

[0011] As a further description of the above technical solution: the length of the screen and the spreading plate are both consistent with the length of the central shaft, and the length of the central shaft matches the front and rear length of the filter box. The screen can be rotated with the central shaft as the base point and the reduction motor can be used to switch the screen and the spreading plate. When the operator pours cucumber seeds onto the screen, the spreading plate can quickly spread the cucumber seeds piled on the screen by starting the stepper motor.

[0012] This utility model has the following beneficial effects:

[0013] This invention relates to a cucumber seed screening and filtration device. Through the combined design of a hydraulic rod and a stepper motor, the hydraulic rod drives the screen in the filter box to slide up and down, supporting the cucumber seeds soaking in water and preventing those that sink to the bottom of the filter box. The stepper motor, on the other hand, drives the screen located at the top of the filter box to move left and right cyclically inside the filter box, facilitating the quick retrieval of empty or shriveled seeds floating on the water surface, thus improving the efficiency of cucumber seed soaking and screening. Simultaneously, the screen can be rotated using a reduction motor with a central axis as the base. By swapping the screen with the spreading plate, when the operator pours the cucumber seeds onto the screen, the spreading plate quickly flattens the seeds accumulated on the screen via the stepper motor. Combined with the water flow generated by the rotating stirring blades at the bottom of the filter box, the cucumber seeds on the screen are quickly dispersed within the filter box, preventing them from sticking together and increasing the success rate of soaking and screening cucumber seeds in the water.

A central shaft 10 is welded to the output shaft of the reduction motor 9. One end of the filter box 1 away from the geared motor 9 is rotatably connected to the front end face of the sliding seat 8 at the top of the slider 20. The top of the central shaft 10 is welded with a flat plate 11, and the bottom of the central shaft 10 is welded with a screen 12. The inner wall of the filter box 1 is slidably connected to the edge of the partition 4. The inner wall of the front hollow shell 5 is in contact with the surface of the moving block 18, and the inner wall of the rear hollow shell 7 is disconnected from the surface of the slider 20. The top of the front hollow shell 5 and the top of the rear hollow shell 7 are both slidably connected to the bottom of the sliding seat 8. The hydraulic rod 2 drives the partition 4 in the filter box 1 to slide up and down, which is used to support the cucumber seeds soaked in water and prevent the cucumber seeds that sink to the bottom from falling to the bottom of the filter box 1. The stepper motor 6 drives the screen 12 located at the top of the filter box 1 to move left and right in a circular motion above the inner side of the filter box 1, which makes it convenient for the filter to quickly scoop up the empty and shriveled seeds floating on the water surface and improve the efficiency of cucumber seed soaking and screening.

[0023] As a further implementation of the above technical solution: the longitudinal cross-section of the connecting plate 3 is L-shaped, and the maximum extension length of the hydraulic rod 2 is the same as half of the internal depth of the filter box 1, so that the hydraulic rod 2 can drive the mesh 4 in the filter box 1 to move up and down through the connecting plate 3, which facilitates the retrieval and soaking of cucumber seeds.

[0024] As a further implementation of the above technical solution: the liquid in the filter box 1 is a 5% salt solution, and the water level is aligned with the middle of the screen 12 located on the upper inner side of the filter box 1. There are two sets of stirring blades 16, and the stirring blades 16 are distributed on the left and right sides of the lower middle inside the filter box 1.

[0026] As a further implementation of the above technical solution: the moving block 18 has a through hole from left to right inside, and the inner wall of the through hole is provided with an internal thread that matches the pitch and helical direction of the threaded rod 17. The stepper motor 6 can drive the threaded rod 17 to rotate forward and reverse. The rotation provided by the stepper motor 6 allows the threaded rod 17 to drive the moving block 18 on its outer side to move left and right inside the front hollow shell 5 when it rotates.

[0027] As a further implementation of the above technical solution: the lengths of the screen 12 and the spreading plate 11 are both consistent with the length of the central shaft 10, and the length of the central shaft 10 matches the front and rear length of the filter box 1. The screen 12 can be rotated with the central shaft 10 as the base point and the reduction motor 9 can be used to switch the screen 12 and the spreading plate 11. When the operator pours cucumber seeds onto the partition 4, the spreading plate 11 can quickly spread the cucumber seeds piled on the partition 4 by starting the stepper motor 6.

[0028] Working principle:

[0029] When using this invention, pour water (95% water, 5% salt) into filter box 1. Simultaneously, start the drive motor 13 on the bottom left side of filter box 1. The drive motor 13 drives the stirring blade 16 at the output end to rotate. Meanwhile, the linkage shaft 14 on the lower right side inside filter box 1 rotates synchronously with the drive motor 13 under the drive belt 15. At this time, the brine begins to be stirred and mixed inside filter box 1 until the brine level reaches the middle position of the mesh 4 located on the upper inner side of filter box 1. Then, turn off the drive motor 13 and start the reduction motor 9 located on the sliding seat 8 on the front side of filter box 1. The reduction motor 9 drives the central shaft 10 at the output end to rotate. Turn the screen 12 and the spreading plate 11 to swap positions, with the screen 12 on top and the spreading plate 11 on the bottom. Then, activate the hydraulic rods 2 on both sides of the filter box 1. The hydraulic rods 2 drive the connecting plate 3 at the output end to rise, and the connecting plate 3 also drives the partition screen 4 in the filter box 1 to move upward until the top of the partition screen 4 is about to touch the spreading plate 11. Pour the cucumber seeds that need to be soaked and screened onto the partition screen 4. Activate the stepper motor 6 on the right end of the front hollow shell 5. The stepper motor 6 drives the threaded rod 17 at the output end to rotate. The moving block 18 on the outside of the threaded rod 17 drives the sliding seat 8 on its top to slide left and right on the top of the front hollow shell 5. The slider 20 inside the hollow shell 7 at the rear end, driven by the central shaft 10 and limited by the limit rod 19, moves synchronously left and right with the moving block 18. At this time, the spreading plate 11 flattens the cucumber seeds on top of the screen 4. After flattening, the stepper motor 6 is turned off, and the hydraulic rod 2 is started, allowing the hydraulic rod 2 to drive the screen 4 to sink into the filter box 1 through the connecting plate 3. The empty cucumber seeds cannot sink due to the buoyancy of the salt water. The operator starts the reduction motor 9 again, allowing the central shaft 10 to drive the spreading plate 11 and the screen 12 to switch again. The stepper motor 6 is turned on again, and the moving block 18 drives the screen 12 to move left and right in a circular motion on the water surface, causing the seeds floating on the water surface to sink. Empty and shriveled seeds are retrieved. After the cucumber seeds on the screen 4 have been soaked for two minutes, the drive motor 13 is started while the stepper motor 6 is turned off. When the drive motor 13 drives the stirring blade 16 to stir the brine in the filter box 1 from the bottom, the cucumber seeds on the screen 4 are dispersed. After 10 seconds, the drive motor 13 is turned off. After standing still for two minutes, the drive motor 13 is turned on again to retrieve the seeds floating on the water surface. The cucumber seeds that sink on the screen 4 are all plump seeds. After the sieve 12 has finished retrieving the seeds, the stepper motor 6 is turned off, the hydraulic rod 2 is started, and the screen 4 is lifted up from the filter box 1 to collect the sieved seeds.
