[0011] This utility model provides a multi-stage sorting device for sea cucumbers, which has the following advantages compared with the prior art: 1. This design provides a multi-stage sorting device for sea cucumbers. It achieves multi-stage transmission by using a stepper motor to drive the drive gear, transmission gear, and rotating rod, and sets a limiting ring on the rotating rod for axial limiting. Compared with the existing technology, it has the stability of the transmission process, avoids the rotating rod from moving around, and enables the subsequent multi-stage screens to operate continuously under stable power input, thereby improving the reliability and service life of the equipment. 2.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution for a multi-stage sorting device for sea cucumbers: like Figure 1 , Figure 2and Figure 4 As shown, the system includes a stepper motor 1. The output end of the stepper motor 1 is connected to a drive gear 2 via a key. A transmission gear 3 is meshed with the outer side of the drive gear 2. A rotating rod 4 is fixedly connected to the top surface of the transmission gear 3 via a key. Transmission gears 5, 6, and 7 are sequentially connected to the outer side of the rotating rod 4 via keys, driving a multi-stage sorting mechanism. A placement plate 8 is fixedly connected to the bottom surface of the stepper motor 1 via bolts. A support plate 9 is fixedly fixed to the top surface of the placement plate 8 via bolts. One side of the support plate 9 has equal length along its length... Three connecting blocks 10 are fixedly connected at intervals. Each connecting block 10 has a rotating hole in its center. The rotating rod 4 passes through and is sleeved in the three rotating holes in sequence. A limiting ring 11 is fixedly installed on the outer side of the rotating rod 4 at the top and bottom surfaces of each connecting block 10 to limit the axial movement of the rotating rod 4. The output end of the stepper motor 1 is connected to the drive gear 2 via a flat key, and drives the rotating rod 4 through the transmission gear 3. Multi-stage transmission is achieved through the transmission gears 5, 6, and 7, enabling the sorting mechanism to operate stably. The rotating rod 4 passes through the connecting blocks 10 and is axially limited by the limiting rings 11, ensuring stable operation of the rotating rod and preventing a decrease in transmission efficiency due to axial movement, thereby improving the overall operational stability and service life of the machine. The stepper motor 1 allows for precise control of the rotation angle of the output end. The stepper motor 1 receives pulse signals through a driver; each pulse received causes the motor 1 to rotate by a fixed angle. By controlling the number of input pulses, the total rotation angle of the stepper motor 1 output can be precisely controlled, thereby driving the drive gear 2, transmission gear 3, and rotating rod 4 to rotate at a predetermined angle. This scheme can ensure the angular accuracy of the multi-stage sorting mechanism, improve the stability and repeatability of the sorting process, and achieve reliable control without the need for an additional angle sensor. The output of the stepper motor 1 rotates 30 degrees to the left and 30 degrees to the right, causing the screen plates 20, 21, and 22 to rotate 30 degrees to the left and 30 degrees to the right repeatedly. The sea cucumbers sway in the screen plates 20, 21, and 22, causing them to fall from the screen holes of the screen plate 20 to the screen holes of the screen plate 21, and some fall from the screen holes of the screen plate 21 to the screen plate 22.

[0016] like Figure 2 As shown, two vertically arranged support rods 12 are fixedly connected to the top surface of the placement plate 8. Three fixing blocks 13 are fixedly sleeved on the outer side of the two support rods 12 along the height direction. Square plate one 14, square plate two 15 and square plate three 16 are fixedly connected to one side of the three fixing blocks 13 respectively, which are used to provide support for the installation bearing of the screen plate. The support rods 12 are set on the top surface of the placement plate 8, and multiple fixing blocks 13 are set on the outer side of them, which are fixedly connected to square plate one 14, square plate two 15 and square plate three 16 respectively, so that the equipment forms a multi-point support structure, thereby enhancing the stability of the installation bearing of the screen plate, reducing the vibration of the screen plate during operation, and improving the sorting accuracy.

[0017] like Figure 1 and Figure 2 As shown, the outer sides of transmission gear 1 (3), transmission gear 2 (5), and transmission gear 3 (6) are respectively meshed with rotating gear 1 (17), rotating gear 2 (18), and rotating gear 3 (19). Rotating gear 1 (17), rotating gear 2 (18), and rotating gear 3 (19) are respectively connected to rotating shaft 1, rotating shaft 2, and rotating shaft 3 via keys. One end of rotating shaft 1, rotating shaft 2, and rotating shaft 3 passes through the shaft holes on block plate 1 (14), block plate 2 (15), and block plate 3 (16), respectively, and screen disc 1 (20), screen disc 2 (21), and screen disc 3 (22) are fixedly connected to their outer ends. The transmission gear set meshes with rotating gear 1 (17), rotating gear 2 (18), and rotating gear 3 (19), and drives screen disc 1 (20), screen disc 2 (21), and screen disc 3 (22) to rotate through rotating shaft 1, rotating shaft 2, and rotating shaft 3, respectively, so that different screen discs can operate synchronously and realize multi-stage sorting function. It has the advantages of compact structure and high transmission efficiency.

[0018] like Figure 1 As shown, the other side of sieve disc 1 20, sieve disc 21, and sieve disc 3 22 are all fixedly connected to the other end of rotating shaft 1, rotating shaft 2, and rotating shaft 3, forming a double-end support structure. Sieve disc 1 20, sieve disc 21, and sieve disc 3 22 are arranged sequentially along the height direction, and their sieve hole size decreases sequentially to achieve step-by-step sorting of sea cucumbers of different sizes. The double-end support structure of sieve disc 1 20, sieve disc 21, and sieve disc 3 22, with their sieve hole size decreasing sequentially, can perform step-by-step sieving of sea cucumbers of different sizes, effectively improving the sorting accuracy, avoiding the problem of large-sized sea cucumbers entering small-hole sieve discs and causing blockage, and improving sorting efficiency and stability.

[0019] like Figure 3 As shown, two square supports are fixedly installed on the bottom surface of the placement plate 8. The bottom surfaces of the two square supports are fixedly connected to the base 23. The top surface of the base 23 is fixedly connected to the support block 24, which is used to provide stable support for the other end of the shaft assembly. The square supports and the base 23 are set at the bottom of the placement plate 8, and the other end of the shaft is stably supported by the support block 24, which further improves the concentricity and stability of the shaft operation, thereby reducing the noise and wear during equipment operation and extending the service life of the whole machine.

[0020] like Figure 2As shown, three rotating holes are equally spaced along the height direction on one side of support block 24. The inner sidewalls of the rotating holes are respectively rotatably sleeved with the other ends of rotating shaft 1, rotating shaft 2, and rotating shaft 3, thereby forming a double-end rotational support for screen disc 1 20, screen disc 21, and screen disc 22 with block plate 1 14, block plate 2 15, and block plate 3 16. The rotating holes on support block 24 form a rotational fit with the other ends of rotating shaft 1, rotating shaft 2, and rotating shaft 3, constituting a double-end support for the screen disc, further ensuring the stability of the screen disc during operation, avoiding shaking or deformation caused by unilateral force on the screen disc, thereby improving the reliability of sorting.

[0021] like Figure 3 As shown, an electronic scale 25 is fixedly connected to the top surface of support block 24 by bolts. A weighing pan is fixedly installed on the top surface of the electronic scale 25 for real-time weighing of sea cucumbers of different sizes collected, thereby facilitating automatic weighing and data recording. The electronic scale 25 and weighing pan installed on the top surface of support block 24 can weigh the screened sea cucumbers in real time and output data, enabling the equipment to not only complete multi-level sorting, but also achieve automatic weighing and data recording, which facilitates subsequent packaging and quality statistics and improves the automation level of the equipment.

[0022] The working principle of this utility model is as follows: An electronic scale 25 is set on the top surface of the support block 24, and a weighing pan is installed on it for real-time weighing of the collected sea cucumbers. The electronic scale 25 can automatically record the weighing data, which is convenient for subsequent statistics and management, realizing the integrated operation of sorting and weighing, and improving the automation level and practical value of the equipment. When the stepper motor 1 starts, its output end drives the active gear 2 to rotate through the flat key. The active gear 2 meshes with the transmission gear 3, thereby causing the transmission gear 3 to rotate. The top surface of the transmission gear 3 is fixedly connected to the rotating rod 4 through the flat key. When the rotating rod 4 rotates, it drives the transmission gear 2 5, the transmission gear 3 6, and the transmission gear 4 7 to rotate in sequence, realizing multi-stage power transmission. The rotating rod 4 is rotatably connected in each connecting block 10 through the rotating hole, and is axially limited by the limiting ring 11 to ensure the stability of the rotation. The transmission gear 2 5 and the transmission gear 3 6 drive the rotating gear 2 18 and the rotating gear 19 respectively. The three gears 17, 18, and 19 are engaged and rotate. Rotary gears 17, 18, and 19 are connected to rotating shafts 1, 2, and 3 respectively via keys, providing driving force to each shaft. One end of each shaft passes through block plates 14, 15, and 16, while the other end passes through the rotating hole in support block 24, achieving double-end support and thus driving screens 20, 21, and 22 to rotate synchronously. The three sieves 22 are arranged sequentially along the height direction, with the sieve hole size decreasing step by step. When sea cucumbers are put in from the top, they first enter the first sieve 20: smaller sea cucumbers will fall to the lower layer through the sieve holes, while larger sea cucumbers will remain in this layer. Then, they enter the second sieve 21 and the third sieve 22, and the sorting of sea cucumbers of different sizes is completed step by step, avoiding the blockage of small-hole sieves by large-sized sea cucumbers, thereby achieving efficient and continuous grading and sieving. After sorting, sea cucumbers of different sizes fall into the corresponding collection areas.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
