Description

Technical Field

[0001] This utility model relates to the field of grape downy mildew detection and sampling technology, specifically a grape downy mildew detection and sampling device. Background Technology

[0002] Grape downy mildew detection sampling refers to the process of selectively collecting representative samples from different parts of the grapevine (such as leaves, shoots, and fruits) within the grape-growing area, following certain scientific methods and standardized procedures, for subsequent laboratory testing or rapid field diagnosis, in order to determine whether the samples are infected with grape downy mildew and the degree of infection.

[0003] Currently, in the sampling process for detecting downy mildew in grapes, representative samples are collected from different parts of the grapevine (such as leaves, new shoots, and fruits). The collected samples are directly stored in a sampling box. However, the sampling box is opened and then closed in a specific manner. If it is not closed in time, the samples are easily dropped due to tilting during manual sampling, which affects the actual use. Therefore, a sampling device that can solve the above-mentioned drawbacks is needed to improve the efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for detecting grape downy mildew, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0006] A sampling assembly includes a sampling frame and a storage frame. The sampling frame has multiple movable openings equidistantly spaced through its center. Guide frames are fixed to opposite sides of the inner walls of the multiple movable openings. Guide blocks are slidably connected inside the guide frames. A movable spring is fixed to one end of the inner wall of the guide frame. One end of the movable spring is fixed to one end of the guide block. The inner side of the guide block is threaded to opposite sides of the storage frame.

[0007] Furthermore, an isolation plate is fitted at the center of the bottom of the storage rack, and a movable handle is threadedly connected to the center of the front of the storage rack.

[0008] Furthermore, the upper and lower ends of the sampling frame are respectively fitted with an upper cover and a lower cover.

[0009] Furthermore, the sampling assembly also includes a shoulder strap and a waist belt, the shoulder strap being located on the outside of the upper cover and the waist belt being located on the outside of the lower cover.

[0010] Furthermore, the outer surfaces of the upper and lower covers are fixed with support blocks on opposite sides, and support columns are fixed on the outer sides of the support blocks. The outer sides of the upper set of support columns are bolted to the end of the shoulder strap, and the outer sides of the lower set of support columns are bolted to the end of the waist belt.

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.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a sampling device for detecting grape downy mildew, comprising:

[0026] The sampling assembly includes a sampling frame 11 and a storage rack 13. The sampling frame 11 has multiple movable openings 12 equidistantly through its center. Guide frames 14 are fixed to the inner walls of the multiple movable openings 12 on opposite sides. Guide blocks 15 are slidably connected inside the guide frames 14. A movable spring 16 is fixed to one end of the inner wall of the guide frame 14. One end of the movable spring 16 is fixed to one end of the guide block 15. The inner side of the guide block 15 is threaded to the opposite sides of the storage rack 13.

[0027] The sampling rack 11 provides a structural foundation installation environment. The storage rack 13 stores the sampled material. The movable opening 12 allows the storage rack 13 to enter and exit the sampling rack 11. The storage rack 13 is installed by the guide block 15 and can be easily moved by sliding within the guide frame 14. The movable spring 16 limits the storage rack 13 when it is moved out of the sampling rack 11 and can actively retract the storage rack 13 by the reverse force applied by the recovery deformation.

[0028] An isolation plate 114 is fitted in the middle of the bottom of the storage rack 13, and a movable handle 113 is threadedly connected to the middle of the front of the storage rack 13.

[0029] The partition plate 114 divides the internal space of the storage rack 13, allowing samples to be placed in layers, while the movable handle 113 applies force to the storage rack 13 during use.

[0030] The upper and lower ends of the sampling frame 11 are respectively fitted with an upper cover 17 and a lower cover 18;

[0031] The upper cover 17 and the lower cover 18 respectively shield and protect the upper and lower ends of the sampling frame 11.

[0032] The sampling assembly also includes a shoulder strap 111 and a waist belt 112, with the shoulder strap 111 located on the outside of the upper cover 17 and the waist belt 112 located on the outside of the lower cover 18.

[0033] The carrying strap 111 allows the sampling device to be carried on the back, while the waist belt 112 further restricts the carrying of the sampling device, preventing the sample from falling off the device due to the tilt angle of the device during manual operation.

[0034] Support blocks 19 are fixed on both sides of the outer surface of the upper cover 17 and the lower cover 18, and support columns 110 are fixed on the outer side of the support blocks 19. The outer side of the upper set of support columns 110 is bolted to the end of the back strap 111, and the outer side of the lower set of support columns 110 is bolted to the end of the waist belt 112.

[0035] Support block 19 is installed on support column 110, and support column 110 is used to fasten and limit the shoulder strap 111 and waist belt 112.

[0036] Working principle: During grape downy mildew detection and sampling, the sampling device is carried on the back using the shoulder strap 111 and its position is limited by the waist belt 112. After sampling, the storage rack 13 can be opened from top to bottom using the movable handle 113. After the movable handle 113 is applied to the storage rack 13, the guide block 15 slides outward inside the guide frame 14 until the storage rack 13 is moved out of the sampling rack 11. After the sample is placed into the storage rack 13, the movable spring 16 returns to its original shape after the force is released, and the guide block 15 slides inward inside the guide frame 14, which moves the storage rack 13 back into the sampling rack 11, restoring the storage rack 13 to its original position.

[0037] This solution can automatically retract into the sampling rack 11 and autonomously reset itself to its original position, reducing the intensity of manual labor while actively isolating and protecting the sampled material, making it convenient to use and meeting the requirements.

[0038] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0039] It also includes an auxiliary sampling component, which includes a cover plate 21. The cover plate 21 is located above the storage rack 13, and the bottom end of the cover plate 21 is attached to the upper end of the storage rack 13. One end of the cover plate 21 is in contact with the upper part of the inner wall of the movable opening 12.

[0040] The auxiliary sampling component also includes positioning holes 22 and positioning posts. The positioning holes 22 are equidistantly opened at both front ends of the sampling frame 11 and extend out of the storage rack 13 and the cover plate 21. The positioning posts are fitted into the positioning holes 22.

[0041] The contact between the cover plate 21 and the inner wall of the movable opening 12, as well as the contact between its lower end and the upper end of the storage rack 13, ensures the stability of its structure within the sampling rack 11. After the cover plate 21 is connected to the storage rack 13 through the positioning hole 22 and the positioning post, the cover plate 21 can be detached from the sampling rack 11 after the storage rack 13 is removed, actively providing top shielding protection for the removed storage rack 13.

[0042] Working principle: When the storage rack 13 is removed from the sampling rack 11, the positioning post is pre-positioned in the center of the positioning hole 22. At this time, the restriction of the guide block 15 by the movable spring 16 is released, and the storage rack 13 is pulled outward by the movable handle 113 to move it out of the sampling rack 11. Under the application of the removal force, the cover 21 gradually detaches from the inner wall of the movable opening 12 and moves out of the sampling rack 11 along with the storage rack 13, thus covering the top of the storage rack 13.

[0043] This solution can actively shield the upper part of the removed storage rack 13, eliminating the need for secondary shielding operations, saving time and effort, reducing the probability of sample damage, and further improving the effectiveness of use.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
