Description

Technical Field

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

[0002] Konjac seed tubers are the key part of the konjac plant used for reproduction. They have a unique corm shape and contain the nutrients and genetic information necessary for the growth and development of konjac. They play a fundamental role in the propagation and expansion of the konjac population. The quality of konjac seed tubers, including their health, absence of pests and diseases, and richness of internal nutrients, directly affects the growth vitality and stress resistance of subsequent konjac plants. Seed tubers of different sizes show significant differences in germination time, growth rate, and final yield and quality. Seed tubers of the appropriate size can efficiently absorb nutrients and water from the soil under suitable planting conditions, quickly take root and sprout, forming robust plants, thus laying a solid foundation for high yields and abundant harvests. In the industrialization of konjac cultivation, high-quality and appropriately sized konjac seed tubers are one of the core elements for maximizing economic benefits and optimizing product quality.

[0003] Existing sieve-type screening devices separate and screen konjac seed tubers by manually shaking the sieve. This avoids the inefficiency of relying entirely on manual selection to some extent. However, due to the simple sieve structure and manual operation, the sieve aperture is fixed and cannot flexibly adapt to the screening needs of seed tubers of different sizes. In addition, the manual shaking is labor-intensive and difficult to guarantee the uniformity and accuracy of screening, resulting in low screening efficiency and inaccurate grading. This cannot meet the requirements of modern large-scale konjac cultivation for efficient and accurate seed tuber screening, and easily leads to waste of seed tuber resources and instability in subsequent planting results.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a konjac seed tuber screening and grading device, comprising an outer shell 1, two receiving frames 2 inside the outer shell 1, a feeding hopper 3 fixedly installed at the top left end of the outer shell 1, a screening mechanism 4 inside the left side of the outer shell 1, the screening mechanism 4 being used to screen and grade konjac seeds of different sizes, and a quantitative alarm mechanism 5 being provided between the outer shell 1 and the two receiving frames 2, the quantitative alarm mechanism 5 being used to sound an alarm after the receiving frames 2 have collected a certain weight of konjac seeds;

[0033] The screening mechanism 4 includes a screening frame 401, inside which multiple screening rods 402 are fixedly connected at equal intervals. The multiple screening rods 402 adopt a fan-shaped design, which facilitates effective screening according to the shape and size of the konjac seed tubers, so that seed tubers of different sizes can be better separated. Rotating rods 403 are fixedly connected to the left ends of the front and rear sides of the screening frame 401. The ends of the two rotating rods 403 that are far apart are respectively rotatably connected to the front and rear sides of the inner wall of the outer shell 1, ensuring that the screening frame 401 can rotate stably during movement and maintain the smooth progress of the screening operation. A vibration motor 404 is fixedly installed on the right side of the inner shell 1. A vibration plate 405 is fixedly connected to the output end of the vibration motor 404. The left end of the vibration plate 405 is fixedly connected to the right side of the screening frame 401. The vibration motor 404 drives the vibration plate 405 to vibrate, thereby causing the screening frame 401 to vibrate, causing the konjac seed tubers to jump and roll continuously inside the screening frame 401, accelerating the screening speed, improving screening efficiency, and accurately screening and grading konjac seed tubers of different sizes.

[0034] Reference Figure 2 , Figure 4 and Figure 5 Multiple mounting plates 501 are fixedly connected to the inner top wall of the outer casing 1 to ensure the structural stability of the entire quantitative alarm mechanism 5. Multiple retraction springs 502 are fixedly connected at equal intervals to the bottom of the multiple mounting plates 501. These springs can support the components below in the initial state and have a certain buffering and elastic deformation capacity when the weight of the receiving frame 2 changes. Each of the multiple retraction springs 502 has a telescopic sleeve 503 inside, which can assist the retraction springs 502 in stable extension and contraction and prevent them from bending or shifting during the force process. The bottom ends of the multiple telescopic sleeves 503 are fixed. A load-bearing block 504 is connected to support the weight pressure from the receiving frame 2 and transmit the pressure to related components. An L-shaped plate 505 is fixedly connected to each adjacent side of the multiple load-bearing blocks 504, cooperating with an L-shaped plate 506 on the receiving frame 2. This serves to connect and position the receiving frame 2 when it is not overloaded. L-shaped plates 506 are fixedly connected to the top of both the left and right sides of the two receiving frames 2, forming a stable connection structure together with the L-shaped plate 505. This ensures that the receiving frame 2 is relatively fixed in position during normal collection of konjac seed tubers. The multiple L-shaped plates 506 are respectively connected to… Multiple L-shaped plates 505 are slidably connected and interlocked to ensure a stable connection and relative sliding between the two during the sinking of the receiving frame 2. Two fixing plates 507 are fixedly connected to the left and right sides of the inner wall of the outer shell 1, providing installation positions for the load-bearing plate 508 and enhancing the internal structural strength of the outer shell 1. Load-bearing plates 508 are fixedly connected to the inner top walls of the multiple fixing plates 507 to support the sinking receiving frame 2 and transmit pressure. Pressure detection discs 509 are fixedly connected to the top left and right sides of the load-bearing plate 508, enabling accurate detection of pressure transmitted from the receiving frame 2. Pressure changes are monitored to determine whether the konjac seed tubers in the receiving frame 2 have reached the set weight. Two pressure detection discs 509 are perpendicular to the two receiving frames 2 respectively to ensure the accuracy and effectiveness of pressure detection. Two alarm lights 510 are fixedly connected to the front of the outer casing 1, which can visually warn the user that the receiving frame 2 is full. The two alarm lights 510 are electrically connected to the two pressure detection discs 509 respectively to realize the timely conversion and transmission of pressure signals to alarm signals, so that the staff can know the status of the receiving frame 2 in a timely manner and take corresponding measures.

[0035] Reference Figure 1 and Figure 2Two handles 6 are fixedly connected to the front and rear sides of each of the two receiving frames 2. The handles 6 are frosted for easy gripping by operators, effectively preventing slippage during handling and preventing the receiving frames 2 from falling due to slippage. Multiple hinges 7 are fixedly connected to the top rear side of the outer casing 1. Inspection covers 8 are fixedly connected to the bottom front of each hinge 7, facilitating opening and closing for inspection, maintenance, and repair of the internal components. Pull rings 9 are fixedly connected to the top front left and right ends of the inspection covers 8, allowing for easy opening and improving operational convenience. A control console 10 is fixedly connected to the top front of the outer casing 1. Multiple control buttons 11 are fixedly connected to the top of the control console 10, allowing for precise control of various functions of the device, such as starting or stopping screening, and setting quantitative alarm parameters. Support legs 12 are fixedly connected to the four corners of the bottom of shell 1. Anti-slip pads 13 are fixedly connected to the bottom of each support leg 12. The support legs 12 support the entire device and keep it stable. The anti-slip pads 13 can increase the friction with the ground and prevent the device from shifting during operation. Two buzzers 14 are fixedly connected to the middle of the front side of shell 1. The two buzzers 14 are electrically connected to two alarm lights 510 respectively. When the alarm lights 510 are lit, the buzzers 14 will sound simultaneously to remind the staff that the receiving box 2 is full with a stronger sound and light signal, so as to avoid missing the alarm information due to noisy environment or staff negligence. A baffle 15 is fixedly connected to the top of the feeding hopper 3. The baffle 15 is made of rubber and can prevent konjac seed tubers from accidentally splashing out of the feeding hopper 3 during feeding, which can play a good blocking and buffering role. At the same time, the rubber material can avoid damage to the konjac seed tubers.

[0036] Working Principle: The konjac seed tuber screening and grading device mainly relies on the internal screening mechanism 4 to screen and grade konjac seed tubers of different sizes. First, the konjac seed tubers enter the device through the feed hopper 3 at the top left of the outer shell 1. After entering the outer shell 1, the seed tubers fall onto the screening frame 401 of the screening mechanism 4. Multiple fan-shaped screening rods 402 are fixedly connected at equal intervals inside the screening frame 401. When the device starts working, the vibration motor 404 on the right side inside the outer shell 1 starts. The output end of the vibration motor 404 drives the vibration plate 405 to vibrate. Since the left end of the vibration plate 405 is fixedly connected to the right side of the screening frame 401, the screening frame 401 also vibrates. During the vibration process, smaller konjac seed tubers fall through the gaps between the screening rods 402 into the corresponding receiving frame 2 below, while larger konjac seed tubers... Because they cannot pass through the gap of the screening rod 402, they remain on the screening frame 401 and gradually move to the right as the screening frame 401 vibrates, falling into another receiving frame 2. The rotating rods 403 on the left side of the front and rear sides of the screening frame 401 are rotatably connected to the front and rear sides of the inner wall of the outer shell 1, so that the screening frame 401 can maintain a relatively stable rotational connection while vibrating, ensuring the smooth progress of its vibration screening process. As the vibration continues, konjac seed tubers of different sizes will be gradually screened and separated according to their own size and the gap of the screening rod 402, and fall into different receiving frames 2, thereby achieving the purpose of screening and grading konjac seed tubers. It can efficiently and accurately classify konjac seed tubers according to size, which is convenient for subsequent planting operations, greatly improving the work efficiency and quality of konjac seed tuber processing, and reducing the labor intensity and error of manual screening.

[0037] Furthermore, once the konjac seed tubers fall into the corresponding receiving frame 2, the quantitative alarm mechanism 5 begins to function. In the initial state, the contraction spring 502 at the bottom of the mounting plate 501 and its internal telescopic sleeve 503 jointly support the load-bearing block 504, keeping the load-bearing block 504 in a relatively stable position. At this time, the L-shaped plate 505 on the side of the load-bearing block 504 and the L-shaped plate 506 on the top of the receiving frame 2 are tightly fitted together and remain relatively stationary. As the konjac seed tubers accumulate in the receiving frame 2, the weight continues to increase. When the weight reaches the preset value, the overall gravity of the receiving frame 2 begins to overcome the elastic force of the contraction spring 502, and the receiving frame 2 gradually sinks downward. During this process, due to the special connection structure of the L-shaped plate 505 and the L-shaped plate 506, they do not separate but move downward together with the receiving frame 2. The receiving frame 2 continues to sink until its bottom touches the pressure detection plate 509 located on the fixed plate 507. At this moment, the pressure detection plate 509 senses the pressure change from the receiving frame 2 and quickly converts this pressure signal into an electrical signal. This electrical signal is transmitted to the alarm light 510, which is electrically connected to it. Upon receiving the signal, the corresponding alarm light 510 on the front side of the outer casing 1 immediately illuminates, clearly alerting the staff that the receiving frame 2 has collected the set weight of konjac seed tubers. Based on this signal, the staff can promptly replace the receiving frame 2, transferring the konjac seed tubers from the full frame. This effectively achieves precise control of the amount of konjac seed tubers collected in the receiving frame 2. It avoids the problem of overloading or insufficient collection caused by the difficulty of accurately controlling the collection volume manually, improving the automation and precision of the konjac seed tuber screening and grading operation, and significantly reducing labor costs and potential risks caused by human error.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
