Description

Technical Field

[0001] This utility model relates to the field of nut harvesting technology, specifically to a sorting mechanism for a fallen fruit collection device. Background Technology

[0002] With the continuous expansion of fruit and nut planting areas in my country, especially nuts such as chestnuts, olives, and walnuts, the traditional method for harvesting these nuts after they mature is mostly manual. Sometimes, harvesters need to climb trees and use sticks or clubs to knock the nuts down. This method is not only labor-intensive and time-consuming, but also poses certain dangers and is not conducive to safe production operations.

[0003] Currently, some fruit-shaking machines have appeared on the market. These machines shake branches or trunks to pull nuts off trees; the shaken nuts are then collected manually, avoiding the dangers of climbing trees. However, even after the nuts are shaken down, they still require manual collection, removal of damaged nuts, and sorting based on size, which still requires a significant amount of manpower and results in high labor costs. Therefore, it is necessary to design a device that can automatically collect and sort the shaken nuts, and correspondingly, a mechanism that can automatically sort the nuts based on size. Utility Model Content

[0004] To address some or all of the problems existing in the prior art, this utility model provides a sorting mechanism for a fallen fruit collection device. The fallen fruit collection device includes a base and a controller. The sorting mechanism includes a sorting frame connected to the base. The sorting frame is provided with a top sorting filter, a middle sorting filter, and a bottom sorting plate arranged sequentially from top to bottom. The top sorting filter has an array of first perforated holes, and the middle sorting filter has an array of second perforated holes. The diameter of the first perforated hole is larger than the diameter of the second perforated hole. The sorting frame is equipped with a direct vibration device that can drive the sorting frame to vibrate. The base is provided with a detachable first collection frame, a second collection frame, and a third collection frame. The first collection frame is connected to the end of the top sorting filter, the second collection frame is connected to the end of the middle sorting filter, and the third collection frame is connected to the end of the bottom sorting plate.

[0005] As a further improvement of this utility model, the direct vibration device includes multiple direct vibration motors, the direct vibration motors are connected to the outer side wall of the sorting frame, and the direct vibration motors are electrically connected to the controller.

[0006] As a further improvement of this utility model, the sorting rack is provided with multiple vibration buffer mechanisms, which are connected to the machine base.

[0007] As a further improvement of this utility model, the vibration buffering mechanism includes a buffer fixed seat, a buffer elastic element, and a buffer guide seat. The buffer fixed seat is connected to the machine base, the buffer guide seat is connected to the sorting frame, and the two ends of the buffer elastic element are respectively connected to the buffer fixed seat and the buffer guide seat.

[0008] As a further improvement of this utility model, the buffer fixing seat is provided with a guide strip, and a guide slider is provided at one end of the guide strip away from the buffer fixing seat. The buffer guide seat is provided with a guide groove, and the guide slider extends into the guide groove and slides in cooperation with the guide groove.

[0009] As a further improvement of this utility model, there are four vibration buffer mechanisms, and the four vibration buffer mechanisms are distributed in a rectangular shape at the four corner positions of the sorting rack.

[0010] As a further improvement of this utility model, the base is provided with mounting slots at corresponding positions to the first collection frame, the second collection frame and the third collection frame, and the first collection frame, the second collection frame and the third collection frame are respectively connected to the drawer of the mounting slot.

[0011] As a further improvement of this utility model, a guide frame is provided at the corresponding position of the top layer sorting plate, the middle layer sorting plate and the bottom layer sorting plate on the sorting frame. One end of the guide frame is connected to the sorting frame and the other end extends to the top of the corresponding first collection frame, second collection frame or third collection frame.

[0012] As a further improvement of this utility model, there can be multiple intermediate layer sorting plates, and the number of second collection boxes is the same as the number of intermediate layer sorting plates, and their positions are set in a one-to-one correspondence.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves automatic sorting of nuts by size through the use of multi-layer sorting plates and a direct vibration device. Compared with traditional manual sorting methods, it significantly improves sorting efficiency and reduces labor costs. The multi-layer sorting screen structure with progressively smaller apertures from top to bottom can accurately classify nuts into multiple grades according to size, meeting market demands for grading nuts of different sizes and increasing product added value.

[0015] 2. This utility model uses high-frequency micro-amplitude vibration generated by a direct vibration device to make the nuts evenly dispersed and move forward on the sorting screen. At the same time, smaller nuts can pass smoothly through the perforated holes. The vibration mode causes little damage to the nuts and ensures their integrity.

[0016] 3. This utility model effectively absorbs the impact force generated when the sorting frame vibrates by setting a vibration buffer mechanism, reduces the vibration transmitted to the machine base, improves the stability and service life of the equipment, and reduces the operating noise of the equipment.

[0017] 4. This utility model adopts a drawer-type connection collection frame design, which can be quickly pulled out and replaced when the collection frame is full, without affecting the continuity of the sorting work and greatly improving the working efficiency of the equipment.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, a sorting mechanism for a fallen fruit collection device is installed on the fallen fruit collection device, which includes a base 100 and a controller. The base 100 is equipped with a conveying mechanism that can convey nuts to the sorting mechanism. The sorting mechanism includes a sorting frame 1, a direct vibration device, a vibration buffer mechanism 2, and a collection frame assembly 3.

[0026] The sorting frame 1 is connected to the base 100 via a vibration buffer mechanism 2, forming an elastic support. The sorting frame 1 is vertically arranged from top to bottom with a top-layer sorting plate 4, a middle-layer sorting plate 5, and a bottom-layer sorting plate 6. Each sorting plate is inclined towards its end in the horizontal direction at an angle of 5°-10° to facilitate nut rolling. The top-layer sorting plate 4 has evenly distributed first perforated holes 41, and the middle-layer sorting plate 5 has evenly distributed second perforated holes 51, with the diameter of the first perforated holes 41 being larger than the diameter of the second perforated holes 51.

[0027] In practical applications, multiple intermediate layer sorting plates 5 can be set as needed. The diameter of the second perforated hole 51 on each intermediate layer sorting plate 5 decreases from top to bottom, so as to achieve more precise grading of nuts.

[0028] The vertical vibration device includes multiple vertical vibration motors 7, which are evenly distributed on the outer wall of the sorting rack 1 and electrically connected to the controller. The vibration direction of all the vertical vibration motors 7 is consistent with the tilt direction of each sorting plate, ensuring that the nuts roll stably without jamming. During operation, the controller controls the vertical vibration motors 7 to start, generating high-frequency micro-amplitude vibrations, which drive the sorting rack 1 and the sorting plates on it to vibrate, causing the nuts to roll forward in a jumping motion on each sorting plate.

[0029] Four vibration buffer mechanisms 2 are provided, located at the four corners of the sorting frame 1. Each vibration buffer mechanism 2 includes a buffer fixed base 21, a buffer elastic element 22, and a buffer guide seat 23. The buffer fixed base 21 is fixedly connected to the machine base 100, and the buffer guide seat 23 is fixedly connected to the sorting frame 1. The two ends of the buffer elastic element 22 (usually a spring) are fixedly connected to the buffer fixed base 21 and the buffer guide seat 23, respectively. A guide bar 24 is provided on the buffer fixed base 21, and a guide slider 25 is provided at one end of the guide bar 24 away from the buffer fixed base 21. A guide groove 26 is provided on the buffer guide seat 23, and the guide slider 25 extends into and slides within the guide groove 26. The cooperation between the guide slider 25 and the guide groove 26 prevents horizontal displacement of the sorting frame 1 during vibration, ensuring stable vibration of the sorting frame 1 in the vertical direction.

[0030] The collection frame assembly 3 includes a first collection frame 31, a second collection frame 32, and a third collection frame 33. The base 100 has three mounting slots 34, corresponding to the first collection frame 31, the second collection frame 32, and the third collection frame 33, respectively. These collection frames are connected to their corresponding mounting slots 34 via drawers for easy removal and replacement. The first collection frame 31 is connected to the end of the top-layer sorting plate 4, the second collection frame 32 is connected to the end of the middle-layer sorting plate 5, and the third collection frame 33 is connected to the end of the bottom-layer sorting plate 6.

[0031] The sorting rack 1 is equipped with a guide frame 8 at the position corresponding to the end of each sorting plate. The guide frame 8 is an inclined trough structure. One end of the guide frame 8 is connected to the sorting rack 1, and the other end extends to the top of the corresponding collection frame, ensuring that the sorted nuts fall accurately into the corresponding collection frame.

[0032] Work process:

[0033] After the fruit shaker shakes the nuts off the tree, the fallen nuts are collected and gathered by the fruit collection device and conveyed to the top of the top sorting plate 4, allowing them to fall onto the top sorting plate 4. The direct vibration device is activated, driving the sorting frame 1 to vibrate. Under the action of vibration, the nuts disperse and roll forward on the top sorting plate 4. Smaller nuts fall through the first perforation 41 onto the middle sorting plate 5, while larger nuts continue to move on the top sorting plate 4 and eventually fall into the first collection frame 31.

[0034] Nuts that fall onto the intermediate sorting screen 5 continue to move forward under vibration. Smaller nuts fall through the second perforation 51 onto the bottom sorting screen 6, while medium-sized nuts continue moving on the intermediate sorting screen 5 and eventually fall into the second collection frame 32. The smallest nuts on the bottom sorting screen 6 move forward under vibration and eventually fall into the third collection frame 33. In this way, automatic grading and collection of nuts according to size is achieved.

[0035] When a collection box is full, the staff can pull it out of the base 100, replace it with an empty collection box, and continue collecting without affecting the continuous operation of the sorting work.

[0036] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
