Description
Technical Field
[0001] The utility model belongs to the technical field of sampling of wheat rust in the field, and more specifically, particularly relates to a portable sampling device. Background Art
[0002] Wheat rust is commonly known as jaundice. It gets its name because rust-colored pustules are produced at the diseased part, and the epidermis ruptures in the later stage, showing rust-brown powdery substances. Wheat rust can be spread by urediniospores in the form of air currents and lurk on wheat in the form of mycelium waiting for an opportunity to develop. Its main damaged part is mainly the leaves of wheat. At present, in order to effectively control the spread and infection of wheat rust, agricultural technicians will collect and sample the diseased wheat leaves in the field for experimental research. However, the traditional leaf collection work of wheat rust is to conduct multi-point sampling in wheat fields in different areas. The staff will wear gloves to directly pick off the wheat leaves and then uniformly place them in plastic bags and baskets for carrying. Thus, it can be seen that part of the rust mycelium will be contaminated on the gloves during the process of picking wheat leaves, and the structures of plastic bags and baskets are relatively exposed. During the process of walking in the wheat field, the leaves of wheat rust are extremely easy to be left and lost, and the rust mycelium on the hands is easy to contact the wheat, causing healthy wheat to be contaminated with the germ, expanding the infection range of rust in the field and causing greater agricultural economic losses.

[0039] In the embodiments of the present disclosure, the top end of the lower blade 1102 is a serrated structure. During the process of the flip cover 1104 closing and flipping, the serrated structure of the lower blade 1102 and the serrated structure at the bottom end of the upper blade 1108 are staggered with each other front and back, which is convenient for quickly cutting and removing wheat leaves.
[0040] In the embodiment of the present disclosure, the left side and the right side of the sampling box 1101 are both provided with L-shaped grooves near the front end, and the two groups of L-shaped grooves are opposite to each other. The notches of the L-shaped grooves of the sampling box 1101 are arc-shaped curved surface structures. During the process of flipping and closing the flip cover 1104 and the sampling box 1101, the arc-shaped curved surface structure of the sampling box 1101 is convenient for pushing the locking rod 1109, so that the locking rod 1109 can smoothly penetrate into the interior of the sampling box 1101 along the arc-shaped curved surface structure of the sampling box 1101, thereby preventing the sampling box 1101 from getting stuck during the closing process. The L-shaped slotted turning part of the sampling box 1101 is a planar structure. When the pulling spring 1112 drives the locking rod 1109 to fully penetrate the bottom of the L-shaped slot through the connecting block 1111, the planar structure of the L-shaped slotted turning part of the sampling box 1101 locks the locking rod 1109 to the upper limit position, thereby completing the closing and locking of the sampling box 1101 and the flip cover 1104, preventing the sampling box 1101 and the flip cover 1104 from flipping open under the elastic force of the torsion spring 1107, so that the wheat rust leaves can be picked and stored separately in the sampling device 11.
[0041] In the disclosed embodiment, the left and right sides of the flip cover 1104 are provided with two groups of strip-shaped through grooves symmetrically distributed on the left and right sides, and the two groups of locking rods 1109 are respectively inserted into the two groups of strip-shaped through grooves of the flip cover 1104, and the two groups of locking rods 1109 are respectively extended to the left and right sides of the through grooves of the flip cover 1104, and the through grooves of the flip cover 1104 support the locking rods 1109 so that the locking rods 1109 can stably penetrate into the L-shaped slot of the sampling box 1101, and a through groove is provided on the rear side of the flip cover 1104 near the top, and a toggle button 1113 is inserted in the through groove of the flip cover 1104, and the toggle button 1113 extends out of the outside of the through groove, and the toggle button 1113 is pushed to push the connecting block 1111 to move on the outside of the flip cover 1104, so that the locking rods 1109 are separated from the plane structure at the turning point of the L-shaped slot of the sampling box 1101 to be unlocked.
[0042] In the disclosed embodiment, nine groups of long grooves are provided on the upper side of the sampling and collecting box 8, and the long grooves are arranged equidistantly from left to right. The sampling device 11 is inserted into the grooves of the sampling and collecting box 8 and is placed in an interval and classified manner to prevent rust bacteria from different leaves from contaminating each other and affecting the quality of the leaf samples. A circular hole groove and a small groove are provided on the upper side of the sampling and collecting box 8 near the right end. The stylus 6 and the notebook 7 are respectively inserted into the circular hole groove and the small groove of the sampling and collecting box 8, which is convenient for carrying the stylus 6 and the notebook 7, and the leaf sampling information can be recorded at any time.
[0043] In the embodiment of the present disclosure, a through hole penetrating up and down is provided on the upper side of the connecting block 1111. The guiding column 1110 is inserted into the through hole of the connecting block 1111, so that the guiding column 1110 limits the left and right positions of the connecting block 1111, and the connecting block 1111 drives the locking rod 1109 to move directionally along the guiding column 1110. The locking rod 1109 is stably inserted into the L-shaped slot of the sampling box 1101 for locking.
[0044] In the embodiment of the present disclosure, the cushion 2 is made of sponge material. The cushion 2 covers and adheres to the front side of the sampling collection box 8. Through the porous and soft characteristics of the sponge, the sampling collection box 8 fits more closely to the human abdomen, and the portable sampling device is more breathable and comfortable to wear.
[0045] The specific usage mode and function of this embodiment are as follows:
[0046] When the utility model is used to sample wheat rust leaves in the field, the Velcro hook surface 10 sewn on the left belt 1 and the Velcro fleece surface 12 sewn on the right belt 9 are first bonded to each other, so that the left belt 1 and the right belt 9 are tied to the waist of the human body. At this time, the pad 2 on the front side of the sampling collection box 8 fits the abdomen of the human body, and the wearing work of the portable sampling device on the waist and abdomen of the human body is completed. Then, the box cover 3 is flipped open, and the sampling device 11 is taken out of the sampling collection box 8. Then, the toggle button 1113 is manually pushed. The toggle button 1113 pushes the connecting block 1111 to overcome the elastic pulling force of the pulling spring 1112 and move along the guide column 1110. The connecting block 1111 synchronously drives the locking rods 1109 welded on the left and right sides to complete the wearing of the portable sampling device. The plane structure of the L-shaped slot turning part of the sampling box 1101 is completely separated from the sampling box 1101, and then the torsion spring 1107 drives the flip cover 1104 to flip upward around the support rod 1106. At this time, the locking rod 1109 is separated from the L-shaped slot of the sampling box 1101 at the top notch of the L-shaped slot of the sampling box 1101, and the flip cover 1104 and the sampling box 1101 are flipped open. Then, the sampling box 1101 is held in the hand, and the lower blade 1102 is aligned with the picking and cutting part of the rust leaves. Then, the flip cover 1104 is manually pressed. The flip cover 1104 overcomes the elastic force of the torsion spring 1107 and flips downward. The flip cover 1104 drives the upper blade 1108 to flip synchronously. At this time, the upper blade 1108 gradually approaches the picking and cutting part of the rust leaves. The sawtooth structure of 108 cooperates with the sawtooth structure of the lower blade 1102 to quickly cut the rusty leaves. After the cutting is completed, the leaves fall into the sampling box 1101, and then the flip cover 1104 continues to flip downward. At this time, the locking rod 1109 contacts the arc surface structure of the L-shaped slotted notch of the sampling box 1101. The locking rod 1109 gradually penetrates into the L-shaped slot of the sampling box 1101 along the arc surface structure of the sampling box 1101 to overcome the pulling force of the pulling spring 1112. When the locking rod 1109 is separated from the arc surface structure of the L-shaped slotted notch of the sampling box 1101, the locking rod 1109 moves along the plane structure inside the L-shaped slot of the sampling box 1101 under the elastic pulling force of the pulling spring 1112. At this time, the locking rod 1109 The top is attached to the plane structure inside the L-shaped groove of the sampling box 1101, and the plane structure inside the L-shaped groove of the sampling box 1101 locks the locking rod 1109 to the upper limit position. The rust-stricken leaves are closed and placed between the flip cover 1104 and the sampling box 1101 to complete the non-contact rust-stricken leaf sampling work by hand, and then the sampling device 11 in the closed state is inserted into the long groove of the sampling collection box 8, and then the sampling information is recorded on the label plate 5 and the notebook 7 respectively with the stylus 6, and finally the box cover 3 is flipped down and closed, and the magnet block 4 bonded to the box cover 3 magnetizes and attracts the iron sheet 13 bonded to the sampling collection box 8, and the box cover 3 closes and seals the sampling device 11 placed in the sampling collection box 8 to prevent the sampling device 11 from being left behind or lost.
[0047] The installation methods, connection methods or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indexes of all its components are its own technologies, and any implementation that can achieve its beneficial effects can be carried out. The above-mentioned label board 5, stylus 6, notebook, 7 magic hook surface 10, magic fluff surface 12 are all common devices on the market. When purchased and used, only connect them according to the user manual purchased together to use, so it will not be elaborated here.
