Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1-4 ,in, Figure 1 A front cross-sectional view of a preferred embodiment of the chestnut fruit non-destructive sorting device provided by this utility model; Figure 2 This is a schematic diagram of the main structure of this utility model; Figure 3 for Figure 1 An enlarged structural diagram of part A shown in the figure; Figure 4 This is a three-dimensional structural diagram of the camshaft in this utility model.

[0022] A chestnut fruit non-destructive sorting device includes: a sorting box 1; a fixing plate 2 fixed to the inner wall of the sorting box 1; a spring 3 installed on the top of the fixing plate 2; a support plate 4 fixed to the top of the spring 3, the support plate 4 having multiple openings, and sorting plates 5 installed in each of the multiple openings; each of the multiple sorting plates 5 having sieve openings that allow chestnut fruits to pass through, and the multiple sorting plates 5 being arranged on the support plate 4 in ascending order of the inner diameter of the sieve openings; and a power mechanism provided on the sorting box 1 for driving the support plate 4 to shake to assist sorting. The multiple openings, the support plate 4 of the sorting plate 5, and the power mechanism achieve the effect of multi-level non-destructive sorting of chestnuts in a single container. The support plate 4 is fixed to the fixed plate 2 by the spring 3 and shakes under the drive of the power mechanism, so that the chestnuts roll naturally during the shaking process. Chestnuts of different sizes are arranged in order of increasing inner diameter of the sieve openings on the sorting plate 5 and pass through the corresponding sieve openings in sequence to achieve multi-level sorting. This design allows the sorting process to be completed in a single sorting box 1 without the need for multiple sorting devices or complex operations, which simplifies the sorting process, improves sorting efficiency, and avoids collision damage to chestnuts during the sorting process, thus ensuring chestnut quality.

[0023] The power mechanism includes a mounting plate 6 fixed on the sorting box 1, a guide groove 7 disposed on the sorting box 1, a slider 8 slidably mounted in the guide groove 7 and connected to the support plate 4, a servo motor 10 fixed on the mounting plate 6, and a camshaft 19 rotatably mounted on the mounting plate 6 and connected to the output shaft of the servo motor 10 via a coupling. The camshaft 19 contacts the slider 8. By setting up the power mechanism consisting of the mounting plate 6, guide groove 7, slider 8, camshaft 19 and servo motor 10, a stable and controllable swaying power is provided for the support plate 4. The mounting plate 6 provides a fixed base for the servo motor 10 and the camshaft 19. The cooperation between the guide groove 7 and the slider 8 allows the support plate 4 to sway stably along a predetermined path. The camshaft 19 rotates under the drive of the servo motor 10 and contacts the slider 8, thereby pushing the support plate 4 to sway.

[0024] A limiting block 9 is fixed on the slider 8. A ball bearing for reducing friction is embedded on the side of the limiting block 9 near the sorting box 1. The ball bearing contacts the outer wall of the sorting box 1. By setting the limiting block 9 on the slider 8 and the ball bearing embedded on the side of the limiting block 9 near the sorting box 1, the beneficial effect of reducing the friction between the slider 8 and the outer wall of the sorting box 1 and ensuring the stable sliding of the slider 8 is achieved. The ball bearing contacts the outer wall of the sorting box 1. During the sliding process of the slider 8, the rolling of the ball bearing can effectively reduce the direct friction between the two, making the movement of the slider 8 smoother.

[0025] The sorting box 1 is equipped with multiple collection hoppers 12, each located directly below a plurality of openings for collecting chestnuts. Each collection hopper 12 has a guide plate 13 at its bottom for guiding the chestnuts out. The sorting box 1 has a discharge port 14, through which the guide plate 13 extends to the outside of the sorting box 1. By configuring the multiple collection hoppers 12, the guide plate 13, and the discharge port 14 within the sorting box 1, the efficient collection and orderly discharge of chestnuts is achieved. Multiple collection hoppers 12 are located directly below multiple openings on the support plate 4, and can receive chestnuts falling from the corresponding sieve openings, realizing the classified collection of chestnuts after sorting. The guide plate 13 set at the bottom of the collection hopper 12 plays the role of guiding the chestnut fruit to discharge, so that the chestnuts can slide smoothly to the discharge port 14. The guide plate 13 extends to the outside of the sorting box 1 through the discharge port 14, which facilitates the subsequent collection and processing of chestnuts. This design makes the collection and discharge process of chestnuts after sorting smoother and more efficient, reduces manual intervention, and improves production efficiency.

[0026] The bottom of the sorting box 1 is hinged with a hydraulic rod 15 and a support leg 16. The bottom of the hydraulic rod 15 is hinged with a base 17, and the base 17 is fixedly connected to the support leg 16. The hydraulic rod 15 is used to adjust the angle of the sorting box 1. By setting the hydraulic rod 15, support leg 16 and base 17 at the bottom of the sorting box 1, the angle of the sorting box 1 can be flexibly adjusted. The bottom of the hydraulic rod 15 is hinged to the base 17 and to the bottom of the sorting box 1. Together with the fixedly connected support leg 16, they form a stable support structure for the sorting box 1. The telescopic function of the hydraulic rod 15 allows the sorting box 1 to adjust its angle around the support leg 16. This design adapts to different processing needs and site conditions. In practical applications, the tilt angle of the sorting box 1 can be changed by adjusting the hydraulic rod 15 according to the specific requirements of chestnut sorting, thereby optimizing the chestnut sorting path and efficiency, making the chestnut sorting process more flexible and efficient.

[0027] The top of the base 17 is fitted with a collection box 18 for collecting chestnuts. A handle on one side of the collection box 18 provides a gripping point for operation. An elastic pad is fitted over the slider 8 for shock absorption. By setting up the collection box 18 on the top of the base 17, the handle on one side of the collection box 18, and the elastic pad on the slider 8, the chestnut collection process is optimized and the equipment stability is improved. The collection box 18 is located below the discharge port 14 of the sorting box 1 and is used to centrally collect sorted chestnuts, simplifying the collection process and improving work efficiency. The handle on one side of the collection box 18 provides a convenient gripping point for operators, facilitating the handling and movement of the collection box 18. The elastic pad on the slider 8 acts as a shock absorber, reducing noise and vibration caused by collisions during the slider 8's sliding process, making the equipment run more smoothly and helping to extend its service life.

[0028] The spring 3 is equipped with a limiting telescopic rod 11 to limit the extension and retraction path of the spring 3. The limiting telescopic rod 11 is fixed between the fixed plate 2 and the support plate 4. The sorting plate 5 is threaded with a fixing bolt that is threadedly connected to the support plate 4 to stabilize the sorting plate 5. By setting the limiting telescopic rod 11 in the spring 3 and the fixing bolt on the sorting plate 5, the extension and retraction path of the spring 3 and the installation position of the sorting plate 5 are stabilized. The limiting telescopic rod 11, fixed between the fixed plate 2 and the support plate 4, can limit the extension and retraction path of the spring 3 and prevent the spring 3 from shifting or twisting during the extension and retraction process, thereby ensuring the stability of the support plate 4 and making the chestnut sorting process more reliable. At the same time, the fixing bolt threaded on the sorting plate 5 and threadedly connected to the support plate 4 plays a role in stabilizing the sorting plate 5 and preventing the sorting plate 5 from loosening or shifting due to vibration during the sorting process, thus ensuring the accuracy and efficiency of sorting.

[0029] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0030] The working principle of the chestnut fruit non-destructive sorting device provided by this utility model is as follows:

[0031] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated through the electrical control cabinet. The power connection method of each piece of electrical equipment is a mature existing technology and is well known to those in the field. It will not be described in detail here. The servo motor 10 can be a Siemens 1FT7 servo motor, and the hydraulic rod 15 can be an EMG electric hydraulic actuator.

[0032] In use, the chestnuts to be sorted are poured into the support plate 4 inside the sorting box 1. The servo motor 10 is started through the electrical control cabinet. The servo motor 10 drives the camshaft 19 to rotate. During the rotation of the camshaft 19, it contacts the slider 8, pushing the slider 8 to slide in the guide groove 7, which in turn causes the support plate 4 to shake. The chestnuts roll naturally during the shaking of the support plate 4. Since the inner diameter of the screen openings of the multiple sorting plates 5 on the support plate 4 is arranged in order from small to large, chestnuts of different sizes will fall through the corresponding screen openings in sequence, realizing multi-level sorting. The falling chestnuts enter the collection hopper 12 directly below the corresponding opening. The guide plate 13 at the bottom of the collection hopper 12 guides the chestnuts to slide through the discharge port 14 into the collection box 18 at the top of the outer base 17 of the sorting box 1. At the same time, the tilt angle of the sorting box 1 can be changed by adjusting the hydraulic rod 15 according to the actual processing needs and site conditions, optimizing the chestnut sorting path and efficiency.

[0033] Compared with related technologies, the chestnut fruit non-destructive sorting device provided by this utility model has the following beneficial effects:

[0034] This utility model provides a non-destructive chestnut sorting device. By setting a sorting structure in a single sorting box 1, the chestnuts roll naturally during shaking and pass through the corresponding sieves according to the inner diameter of the sieve openings on the sorting plate 5, achieving multi-level sorting without the need for multiple sorting devices or complex operations. At the same time, the natural rolling of the chestnuts through the sieve openings during shaking reduces collisions during the sorting process and ensures the quality of the chestnuts.
