Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically a tuber sorting and screening device for Bletilla striata cultivation. Background Technology

[0002] As a valuable economic crop with high medicinal value, the size of Bletilla striata tubers directly affects the survival rate of planting and the quality of subsequent products. Therefore, it is necessary to accurately grade and screen Bletilla striata tubers before planting in order to achieve the purpose of planting according to specifications and improving planting efficiency.

[0003] There are significant technical shortcomings in the current sorting and screening process of Bletilla striata tubers: On the one hand, traditional manual sorting is inefficient and difficult to adapt to the needs of large-scale planting. Moreover, manual operation is prone to damage to the tuber skin due to improper force control, which affects the tuber activity. Existing mechanical screening equipment mostly uses a single screen or fixed screen cylinder structure, which can only achieve single-size screening. Multiple repeated operations are required to complete multi-size grading, which is not only inefficient, but also prone to tuber mixing due to repeated handling, resulting in poor grading accuracy and failing to meet the requirements of refined planting of Bletilla striata tubers.

[0004] On the other hand, some existing screening equipment lacks a targeted tuber protection design. When tubers fall from the screen cylinder to the collection component, they are easily damaged by direct impact on the bottom of the collection box. At the same time, when tubers enter the screen cylinder from the feeding structure, they often hit the inner wall of the screen cylinder due to the lack of guidance in the falling path, which further increases the tuber loss rate and reduces the tuber utilization rate. It is difficult to adapt to the characteristics of thin and easily damaged Bletilla striata tubers, resulting in economic losses for growers.

[0005] To address the aforementioned problems, the inventors proposed a tuber sorting and screening device for Bletilla striata cultivation. Utility Model Content

[0006] To address the problems of low grading efficiency and easy damage to Bletilla striata tubers during the screening process, this utility model aims to provide a tuber sorting and screening device for Bletilla striata cultivation.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: a tuber sorting and screening device for Bletilla striata cultivation, comprising a shell, a screening mechanism fixedly provided inside the shell, a collection component fixedly provided at the bottom of the shell, a feeding mechanism fixedly installed on one side of the top of the shell, and a support fixedly installed on one side of the bottom of the shell.

[0008] Preferably, the screening mechanism includes a base, which is fixedly connected to the top of the support. A motor is bolted to the top of the base. The output end of the motor passes through the outer shell and is fixedly connected to a rotating shaft. A screen cylinder is fixedly connected to the end of the rotating shaft. Three screen cylinders are coaxially arranged along the axial direction of the rotating shaft. The screen hole diameter of the three screen cylinders decreases sequentially along the feeding direction. A discharge port is fixedly provided at the bottom of the screen cylinder.

[0009] Preferably, the collection assembly includes a collection box, which is fixedly connected to the bottom of the outer shell. The collection box has three drawers that slide inside. These three drawers are arranged sequentially along the axial direction of the screen cylinder within the collection box, and the openings of the drawers correspond to the discharge ports below different aperture sections of the screen cylinder. A buffer plate is fixedly installed inside each drawer, and a buffer element is fixedly installed at the bottom of the buffer plate. A compression spring is fitted onto the outer surface of the buffer element. The top end of the compression spring is welded to the bottom of the buffer plate, and the bottom end of the compression spring is welded to the inner bottom wall of the drawer. Four compression springs are evenly distributed along the length of the buffer plate below the same buffer plate.

[0010] Preferably, the feeding mechanism includes a connecting seat, which is bolted to the top of the housing. A feeding hopper is bolted to one side of the connecting seat. A support frame is fixedly installed at the bottom of the feeding hopper. An inclined guide plate is fixedly provided inside the feeding hopper, and the inclined direction of the guide plate is towards the screen cylinder inside the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes three coaxial sieve cylinders with progressively smaller apertures along the feeding direction, driven by a motor, to achieve multi-specification grading of Bletilla striata tubers in a single sieve pass, eliminating the need for repeated operations. The three drawers precisely correspond to the discharge ports of the respective sieve cylinders, preventing tuber mixing and significantly improving the efficiency of traditional screening methods, thus meeting the needs of large-scale cultivation. 2. This utility model uses a buffer plate inside the drawer and a buffer component with a compression spring to buffer the impact force of falling tubers. The inclined guide plate inside the feed hopper guides the tubers to enter the screen cylinder smoothly, reducing impact damage. The dual protection design reduces the tuber breakage rate and ensures tuber activity and planting benefits. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a tuber sorting and screening device for Bletilla striata cultivation, including a shell 1, a screening mechanism 2 fixedly installed inside the shell 1, a collection component 3 fixedly installed at the bottom of the shell 1, the collection component 3 is used to receive Bletilla striata tubers of different specifications after screening, a feeding mechanism 5 is fixedly installed on one side of the top of the shell 1, the feeding mechanism 5 is the channel for Bletilla striata tubers to enter the device, and the fixed position on one side of the top of the shell 1 allows the tubers to smoothly enter the internal sieve cylinder 24, and a bracket 4 is fixedly installed on one side of the bottom of the shell 1.

[0020] The screening mechanism 2 includes a base 21, which is fixedly connected to the top of the support 4. A motor 22 is bolted to the top of the base 21, providing power to the screening mechanism 2. The bolted connection facilitates the installation, disassembly, and subsequent maintenance of the motor 22. The output end of the motor 22 passes through the outer casing 1 and is fixedly connected to a rotating shaft 23. The fixed connection to the rotating shaft 23 enables the rotating shaft 23 to rotate synchronously, providing power for the rotation of the screen cylinder 24. The end of the rotating shaft 23 is fixedly connected to the screen cylinder 24, and the fixed connection of the rotating shaft 23 to the screen cylinder 24 enables the screen cylinder 24 to rotate synchronously. The rotation of the screen cylinder 24 enables the screening and separation of Bletilla striata tubers. Three screen cylinders 24 are coaxially arranged along the axis of rotation 23. This allows for the grading and screening of tubers of various sizes. The aperture of the screen holes in the three screen cylinders 24 decreases sequentially along the feeding direction, allowing the tubers entering the screen cylinders 24 to be separated according to size. Larger tubers are screened in the rear screen cylinder 24, while smaller tubers are screened in the front screen cylinder 24, ensuring accurate grading. A discharge port 25 is fixedly provided at the bottom of the screen cylinder 24.

[0021] The collection component 3 includes a collection box 31, which is fixed to the bottom of the outer shell 1 and precisely aligned with the discharge port 25 below the sieve cylinder 24 to ensure that the tubers fall in smoothly. The collection box 31 is fixedly connected to the bottom of the outer shell 1. The collection box 31 has three drawers 32 that slide inside. The three drawers 32 correspond one-to-one with the three sieve cylinders 24 to collect tubers of different sizes after screening. The three drawers 32 are arranged sequentially along the axial direction of the sieve cylinder 24 inside the collection box 31, and the openings of the drawers 32 correspond to the discharge ports 25 below different aperture sections of the sieve cylinder 24. The sequential arrangement of the drawers 32 along the axial direction of the sieve cylinder 24 ensures that each drawer 32 is precisely aligned with the discharge port 25 of the corresponding sieve cylinder 24. A buffer plate 33 is fixedly installed inside the drawer 32, and a buffer element 34 is fixedly installed at the bottom of the buffer plate 33 to catch the tubers falling from the discharge port 25 and prevent the tubers from directly hitting the bottom of the drawer 32 and causing damage.

[0022] A compression spring 35 is fitted on the outer surface of the buffer 34. The compression spring 35 is fitted on the outer surface of the buffer 34 to enhance the buffering effect and protect the buffer 34 from direct wear. The top of the compression spring 35 is welded to the bottom of the buffer plate 33 and the bottom of the compression spring 35 is welded to the inner bottom wall of the drawer 32. Four compression springs 35 are evenly distributed along the length of the buffer plate 33 under the same buffer plate 33. The even distribution of the four compression springs 35 can make the buffer plate 33 bear force evenly.

[0023] The feeding mechanism 5 includes a connecting seat 51, which is bolted to the top of the outer shell 1. The bolted connection facilitates the installation and disassembly of the connecting seat 51 and ensures a stable connection between the feeding mechanism 5 and the outer shell 1. A feeding hopper 52 is bolted to one side of the connecting seat 51. An inclined guide plate is fixedly installed inside the feeding hopper 52. The inclined guide plate can guide the tubers in the feeding hopper 52 to slide down in a fixed direction, preventing the tubers from accumulating and clogging inside the feeding hopper 52. The inclined direction of the guide plate is towards the screen cylinder 24 inside the outer shell 1. A support frame 53 is fixedly installed at the bottom of the feeding hopper 52. The support frame 53 is used to assist in supporting the feeding hopper 52 and enhance the load-bearing capacity of the feeding hopper 52.

[0024] Working principle: The tubers of Bletilla striata to be screened are manually or by conveying equipment into the feeding hopper 52 of the feeding mechanism 5. The inclined guide plate inside the feeding hopper 52 plays a guiding role, guiding the tubers to slide smoothly into the screen cylinder 24 inside the outer shell 1 along a fixed path, avoiding damage caused by the tubers falling randomly and hitting the inner wall of the screen cylinder 24.

[0025] After the motor 22 is started, the motor 22 drives the three coaxially arranged screen cylinders 24 to rotate synchronously through the rotating shaft 23 at the output end. Since the screen hole diameter of the three screen cylinders 24 decreases sequentially along the feeding direction, the tubers will be graded and separated due to their size differences as they rotate with the screen cylinders 24. Large-sized tubers cannot be intercepted by the front and middle screen cylinders 24 and eventually leak out from the screen hole of the rear screen cylinder 24. Medium-sized tubers can pass through the front screen cylinder 24 but are intercepted by the middle screen cylinder 24 and leak out from the screen hole of the middle screen cylinder 24. Large-sized tubers are intercepted by the rear screen cylinder 24 and leak out from the screen hole of the rear screen cylinder 24.

[0026] After the tubers of each size are discharged, they fall precisely into the three drawers 32 arranged in sequence along the axial direction of the sieve cylinder 24 through the discharge port 25 below the corresponding sieve cylinder 24 in the collection component 3. When the tubers fall into the buffer plate 33 inside the drawer 32, the buffer component 34 at the bottom of the buffer plate 33 and the compression spring 35 are subjected to force and undergo elastic deformation, which converts the impact force of the falling tubers into the elastic potential energy of the spring, effectively weakening the impact force and preventing the tuber skin from being damaged due to direct impact with the bottom of the drawer 32.

[0027] After the screening is completed, turn off motor 22 and pull drawer 32 out of collection box 31 to obtain Bletilla striata tubers of different grades. The whole process realizes automated grading and screening and protective collection of Bletilla striata tubers.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
