Description

Technical Field

[0001] This utility model relates to the technical field of plant seed cutting equipment, specifically to a plant seed cutting device. Background Technology

[0002] In recent years, genetic engineering and molecular breeding techniques have significantly shortened breeding cycles and improved the selection efficiency of superior genes, providing new avenues for breeding perennial plants such as *Leymus chinensis*. Callus culture is fundamental to the establishment of plant regeneration and genetic transformation systems. Under suitable conditions, plant explants such as roots, stems, leaves, and seeds can produce callus tissue. In experiments, seeds are descrambled with 50% sulfuric acid and shaken on a shaker for 20-30 minutes; then soaked in deionized water + 7 mg / L 2,4-D for at least 5 hours; then sterilized with 3% sodium hypochlorite for 20 minutes; finally, the seeds are longitudinally cut along their long axis, and then placed on callus induction medium for one month to obtain callus tissue.

[0003] Currently, researchers primarily use scalpels to cut seeds individually or use a cutting block to cut them in batches. However, the seeds used in the experiments are generally small, about 2 mm wide and 6.5 mm long, and each experiment requires more than 500 seeds to meet the needs of subsequent experiments. Therefore, the current cutting operation is very time-consuming and laborious, and the cutting results are inconsistent, which significantly affects the progress of the experiments.

Detailed Implementation The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0017] Example 1 refer to Figures 1-3 This embodiment provides a plant seed cutting device, which aims to solve the problem that the plant seed cutting operation is time-consuming and laborious in the existing callus culture. The specific structure of this embodiment will be described in detail below.

[0018] A plant seed cutting device, comprising a cutting support and a cutting assembly; The cutting bracket includes a base plate 1 and a top plate 2, which are connected by a column 3. The top plate 2 has an mounting plate 4 on its upper surface and an electric push rod 5 on its mounting plate 4. Specifically, the cutting assembly includes a corresponding upper cutting plate 6 and a lower cutting plate 7; the upper cutting plate 6 passes through the support top plate 2 and is installed at the output end of the electric push rod 5, while the lower cutting plate 7 is placed on the support bottom plate 1.

[0019] In this embodiment, the upper surface of the upper cutting plate 6 is provided with double connecting ears, and the output end of the electric push rod 5 is provided with a single connecting ear. The double connecting ears and the single connecting ear are connected and fixed by a pin, thereby connecting the upper cutting plate 6 and the output end of the electric push rod 5, while the lower cutting plate 7 is placed on the support base plate 1.

[0020] Then, the plant seeds to be cut are placed between the upper cutting plate 6 and the lower cutting plate 7. The upper cutting plate 6 is driven to move down by the electric push rod 5 to quickly and batch cut the plant seeds to be cut on the lower cutting plate 7, which improves the operating efficiency and the uniformity of cutting.

[0021] Specifically, the lower surface of the upper cutting plate 6 is evenly provided with multiple mounting grooves 8, and each mounting groove 8 is equipped with a cutting blade 9.

[0022] Specifically, the upper surface of the cutting plate 7 is provided with multiple placement slots 10 that fit into the mounting slots 8.

[0023] Specifically, one end of the placement groove 10 is provided with a connecting groove 11 opened on the upper surface of the cutting lower plate 7.

[0024] In this embodiment, the upper cutting plate 6 and the lower cutting plate 7 are both made of corresponding rectangular blocks. Multiple mounting slots 8 are evenly provided on the lower surface of the upper cutting plate 6, and a cutting blade 9 is installed in each mounting slot 8.

[0025] Alternatively, each mounting groove 8 is a straight groove with open ends, the length and width of which match the cutting blade 9, so that the cutting blade 9 can be tightly embedded in the mounting groove 8, and the cutting blade 9 is further fixed by a long pin passing through the upper cutting plate 6, and the cutting edge of the cutting blade 9 is placed outside the mounting groove 8.

[0026] Optionally, the height of the cutting blade 9 outside the mounting slot 8 is greater than the depth of the placement slot 10.

[0027] Optionally, the spacing between adjacent placement slots 10 is 10mm. The upper part of the longitudinal section of each placement slot 10 is a rectangle with a length of 3mm and a width of 2mm, with rounded corners on the sides, and a circle with R1 at the bottom, so that the seeds can be stuck without damaging them when cutting.

[0028] Specifically, a limiting plate 12 is provided on the supporting base plate 1, and a limiting groove 13 is provided on the limiting plate 12 to fit the cutting lower plate 7. The cutting lower plate 7 is embedded in the limiting groove 13.

[0029] Specifically, first limiting blocks 14 are symmetrically arranged on the limiting plates 12 located on both sides of the limiting groove 13, and second limiting blocks 15 that fit with the first limiting blocks 14 are respectively arranged on both sides of the cutting upper plate 6.

[0030] In this embodiment, the limiting plate 12 is placed on the supporting base plate 1, and threaded holes are opened at both ends of the column 3. The bottom of the column 3 is connected by bolts passing through the reserved through holes of the supporting base plate 1 and the limiting plate 12 and being inserted into the threaded hole of the column 3. The reserved through hole of the supporting base plate 1 is a stepped hole. The top of the column 3 is connected by bolts passing through the reserved through hole of the supporting top plate 2 and being inserted into the threaded hole of the column 3.

[0031] The limiting groove 13 on the limiting plate 12 fits into the cutting lower plate 7 so that the cutting lower plate 7 can be embedded into the limiting groove 13.

[0032] Furthermore, when the electric push rod 5 drives the upper cutting plate 6 to approach the lower cutting plate 7, the first limiting block 14 and the second limiting block 15 engage with each other to ensure that the falling position of the upper cutting plate 6 will not shift, thereby ensuring that the cutting blade 9 will not shift or overcut during the cutting process.

[0033] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
