The invention discloses a wood seedling transplanter for forestry. The transplanter comprises guiding rails, rail brackets and a rolling component, wherein a power unit is fixed on one side of the rolling component through a mounting bracket, and one side of the power unit is connected with a gearbox which is in transmission connection with a cutting device. Openings are formed in the guiding rails, when in use, the transplanter is used for enclosing wood seedlings through the openings, so that the purpose that soil cutting is performed by using the wood seedlings as a circle; the rolling component rotates along the guiding rails, so that the situation that the soil cutting does not deviate from the circular rails is ensured; in a transplant process, the roots of the wood seedlings respectively carry circular soil balls, so that integrity of the roots of the wood seedlings is ensured to the maximum. The rail brackets are connected with a rail ring, at the same time, the rail brackets have the functions of absorbing shock, preventing soil from being broken and ensuring the integrity of the soil balls.

The invention discloses a mechanical knife sharpening device, which comprises a fixed seat, a base is arranged above the fixed seat, a sharpening device is arranged above the base, and the sharpening device includes a knife holder, a first rotating body and a second rotating body, The tool holder includes a tool holder, a sliding body and a fixed frame. A spring is arranged between the tool holder and the sliding body. The first rotating body is composed of a first disc, a first rib column and a second disc. The first disc, the second A rib column and the second disc are connected together by screws, the second rotating body includes a perforated disc, a second rib column and a third disc, and the second rib column is arranged between the perforated disc and the third disc. Between the disks, there are dials on the first disk, the second disk and the third disk, which have good general performance and are suitable for sharpening various mechanical knives. The operation is simple and can realize the function of sharpening mechanical knives. And in the sharpening process, it has good safety and reliability, good shock absorption effect, and can avoid the problem of tool shattering.

The invention discloses a welding structure of a lithium battery pole piece foil and a pole ear, including an electrode formed by stacking a plurality of pole piece foils, the electrodes include a positive electrode and a negative electrode, and the pole piece foils are welded and connected One side of the electrode is welded with tabs, the other side of the electrode is provided with a shock absorber, the inner side of the shock absorber is provided with a shock absorber cavity, the shock absorber cavity is filled with high temperature resistant glue, and the periphery of the shock absorber extends outward A ring-shaped welding surface is formed, and the welding connection between the ring-shaped welding surface and the electrode is formed; a through hole is provided at the bottom of the shock-absorbing cavity; The baffle is attached to the outer end surface of the electrode, and the tab connecting piece is welded to the inner surface of the tab. Therefore, the present invention has the beneficial effect of improving the service life of the lithium battery by preventing the outermost pole piece foil from being crushed by ultrasonic waves when the pole piece foil is welded to the tab.

This invention relates to a new distinct early maturing, high seed and husk yielding variety of psyllium (Plantago ovata) designated as var. ‘Mayuri’ with the distinct pigment marker of the panicles relatable to the maturity thereby indicating the right harvesting stage to prevent the seed shattering, a problem in psyllium. This variety was developed by mutation breeding (gamma rays irradiation) and propagated by seeds for commercial cultivation. The new variety could be differentiated from the other variety through unique RAPD profile and has been tested for uniformity and stability of characters defined. Psyllium plant ‘Mayuri’ with stage marker and early maturity.
