Description

Technical Field

[0001] This utility model relates to the field of agricultural measurement tools, specifically an adjustable wheat ear morphology measuring fixture. Background Technology

[0002] In wheat breeding and variety improvement, spike traits are one of the important indicators for evaluating wheat yield potential and varietal characteristics. Common spike traits include spike length, spikelet number, grain number per spike, and spike density. To accurately obtain these data, researchers usually need to fix the wheat spike on a specific device for stable and precise measurements. Therefore, designing a reasonably structured and easy-to-operate wheat spike fixing device is of great significance for improving measurement efficiency and data accuracy.

[0003] Currently, most of the fixing devices used for measuring wheat ear traits are fixed structures with non-adjustable size and clamping position, making it difficult to adapt to wheat ears of different lengths and diameters. Furthermore, most existing fixing frames adopt a static clamping method, which restricts the position of the wheat ear after it is fixed, making it impossible to rotate flexibly and observe from multiple angles during the measurement process. This causes inconvenience for researchers to comprehensively view the ear structure, count the number of spikelets, or record morphological characteristics, affecting measurement efficiency and data integrity. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable fixing frame for measuring wheat ear traits, in order to solve the problems mentioned in the background art, such as the current fixing devices used for measuring wheat ear traits having a simple structure, non-adjustable clamping position, inability to adapt to wheat ears of different sizes, and limited observation angle of the ear during the measurement process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable wheat ear trait measuring and fixing frame, including a main support frame, with adjustable sliding frames at both the upper and lower ends of the main support frame, a rotating shaft passing through the outer end of the frame, a screw-fitting block fixed at one end of the rotating shaft inside the frame, a positioning plate at the front edge of the screw-fitting block, and a fine-tuning support block inside the positioning plate for supporting the wheat ear end fixed by transparent adhesive, and a linkage locking assembly consisting of a locking sleeve and a positioning shaft on both sides of the frame.

[0006] Preferably, the locking sleeves are symmetrically welded and fixed to the outer walls of the two sides of the adjacent end of the support frame, and the positioning shaft is inserted between the locking sleeves on the same side of the same group.

[0007] Preferably, the main support bracket has an overall arc-shaped structure, and multiple slide rail guide grooves are evenly arranged on its inner wall along the length direction, with a fulcrum module slidably connected to each slide rail guide groove.

[0008] Preferably, the inner wall of the adjacent end of the support frame is symmetrically provided with sliding guide blocks, and the outer walls of the upper and lower ends of the main support frame are symmetrically provided with sliding guide grooves that cooperate with the structure of the sliding guide blocks.

[0009] Preferably, a rubber damping ring is fitted and fixed at the connection between the outer end of the support frame and the rotating shaft, and the rotating shaft passes through the outer end of the support frame via the rubber damping ring.

[0010] Preferably, a fixed block is welded to the inner end of the positioning plate, and a fine-tuning bolt is inserted through the middle of the fixed block by a threaded structure. Furthermore, an elastic tension block is connected between the inner edge of the fixed block and the inner edge of the fine-tuning support block.

[0011] Compared with existing technologies, the advantages of this utility model are: the adjustable wheat ear trait measuring fixture is flexible in adjustment, can adapt to wheat ears of different lengths and diameters, and facilitates multi-angle rotation observation, thus improving measurement efficiency and data accuracy. This adjustable wheat ear trait measuring fixture achieves flexible height adjustment through the sliding fit design of the main support bracket and the support frame. The connection structure between the rotating shaft and the screw-fit block allows the positioning plate to rotate the wheat ear, facilitating multi-angle observation. Simultaneously, the fine-tuning support block inside the positioning plate can adapt to ears of different end sizes, improving clamping stability. The linkage locking components on both sides of the support frame can quickly lock after adjustment. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: an adjustable wheat ear trait measurement fixture, including a main support frame 1, with adjustable sliding support frames 2 at both the upper and lower ends of the main support frame 1. Both sides of the support frames 2 are arc-shaped, and a rotating shaft 3 passes through the outer end of the support frame 2. A screw-fitting block 4 is fixed to one end of the rotating shaft 3 inside the support frame 2. A positioning plate 5 is provided at the front edge of the screw-fitting block 4. A fine-tuning support block 6 is provided inside the positioning plate 5. Both the fine-tuning support block 6 and the positioning plate 5 are arc-shaped. The fine-tuning support block 6 is slidably connected inside the positioning plate 5. The fine-tuning support block 6 is used to support the wheat ear end fixed by transparent adhesive. Furthermore, both sides of the support frame 2 are provided with a linkage locking assembly consisting of a locking sleeve 7 and a positioning shaft 8. This structure allows for sliding adjustment in the height direction through the support frames 2 at both the upper and lower ends of the main support frame 1 to accommodate wheat ear samples of different lengths. The rotating shaft 3 at the outer end of the support frame 2 cooperates with the screw-fitting block 4, enabling the positioning plate 5 to rotate the ear. The structure allows researchers to observe the morphological characteristics of the ear from different angles. The fine-tuning support block 6 inside the positioning plate 5 can be adjusted according to the size of the ear end, ensuring stable support and preventing ear displacement or detachment during measurement. The linkage locking assembly, consisting of the locking sleeve 7 and the positioning shaft 8, can quickly lock after the support frame 2 is adjusted to its position, preventing structural loosening from affecting measurement accuracy. This overall structure achieves flexible adjustment, stable clamping, and multi-angle observation of wheat ear samples, solving the problems of fixed clamping positions, inability to adapt to different ear sizes, and limited observation angles in existing fixing devices. It effectively improves measurement efficiency and data accuracy. The locking sleeve 7 is symmetrically welded and fixed to the outer walls of both sides of the adjacent end of the support frame 2. Locking screws are connected to the locking sleeve 7 via a threaded structure. The positioning shaft 8 is inserted between the locking sleeves 7 on the same side. After the support frame 2 is slidably adjusted to its position at both ends of the main support frame 1, tightening the locking screws locks the locking sleeve 7 and the positioning shaft 8. The outer wall generates a clamping force, thereby achieving a stable lock on the support frame 2 at any adjustable position, ensuring that the support frame 2 will not slide or shift during the measurement process. The main support frame 1 has an overall arc-shaped structure, with multiple slide rail guide grooves evenly arranged along its length on its inner wall. Each slide rail guide groove is slidably connected to a fulcrum module 9. This structure can be used to move the fulcrum module 9 to a suitable position along the slide rail guide groove, serving as an auxiliary support point for different parts of the wheat ear, effectively enhancing the support stability for long or curved ears, and preventing the ear from bending or shifting due to gravity, thereby improving the ease of operation and the accuracy of data acquisition during the measurement process. Sliding guide blocks 10 are symmetrically welded and fixed on the inner wall of adjacent ends of the support frame 2, and sliding guide grooves 11 that cooperate with the structure of the sliding guide blocks 10 are symmetrically arranged on the outer walls of the upper and lower ends of the main support frame 1. When the support frame 2 slides up and down along the main support frame 1, the cooperation between the sliding guide blocks 10 and the sliding guide grooves 11 plays a guiding and limiting role, ensuring that the support frame 2 runs smoothly and is accurately positioned during the adjustment process.To prevent offset or wobbling, a rubber damping ring 12 is fitted and fixed at the connection between the outer end of the support frame 2 and the rotating shaft 3. The rotating shaft 3 passes through the outer end of the support frame 2 via the rubber damping ring 12. This structure provides necessary frictional resistance when the rotating shaft 3 is rotated, making the rotation smoother and more controllable. It avoids unintentional rotation caused by slight external forces, ensuring the positional stability of the positioning support plate 5 and the wheat ears on it. A fixed block 501 is welded and fixed to the inner end of the positioning support plate 5, and the middle of the fixed block 501 is threaded. The structure incorporates fine-tuning bolts 502, and an elastic tension block 503 connects the inner edge of the fixed block 501 to the inner edge of the fine-tuning support block 6. The fine-tuning bolts 502 can achieve radial displacement by rotating on the fixed block 501 via a threaded structure, thereby pressing the fine-tuning support block 6 to different positions. This allows for precise adjustment of the clamping position at the end of the wheat ear, ensuring adaptation to ears of different diameters and shapes. Simultaneously, the elastic tension block 503 provides elastic stretching force during adjustment, working in conjunction with the fine-tuning support block 6 to finely adjust the position.

[0019] Working principle: When using this adjustable wheat ear morphology measuring fixture, firstly, adjust the position of the support frame 2 on the main support frame 1 according to the length of the wheat ear. After ensuring that the support frame 2 slides smoothly to the appropriate height through the cooperation of the sliding guide block 10 and the sliding guide groove 11, tighten the locking screw on the locking sleeve 7 to press the positioning shaft 8, thereby stabilizing and locking the position of the support frame 2. Next, the end of the wheat ear is glued and fixed to the fine adjustment support block 6 with transparent adhesive, and the radial displacement is adjusted by rotating the fine adjustment bolt 502 according to the specific size of the ear to accurately adapt to ears of different diameters. At the same time, the elastic tension block 503 provides the necessary elastic support. Subsequently, if it is necessary to observe the ear morphology from multiple angles, the positioning plate 5 and the ear fixed on it can be rotated by rotating the shaft 3. The rubber damping ring 12 provides the necessary frictional resistance in this process to ensure that the rotation is smooth and controllable. If it is necessary to further enhance the stability of long ears or curved ears, the fulcrum module 9 can be moved along the slide rail guide groove on the inner wall of the main support frame 1 to an appropriate position as an auxiliary support point, thereby completing a series of tasks.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
