The application discloses a hydraulic motor with a floating oil seal protection device, which comprises a motor assembly, a shell covering the motor assembly, and a speed reduction assembly connected with one end of the motor assembly, wherein a gear ring is arranged on the speed reduction assembly, a first matching gap is arranged at the joint of the motor assembly and the gear ring, an annular sleeve is arranged on the outer side of the first matching gap, a groove is arranged on the end face of the sleeve close to the gear ring, a sealing ring is arranged annularly on the gear ring in the groove, the sealing ring is in interference fit with the gear ring, and an O-shaped ring is arranged on the outer side of the sealing ring. The protection device of the floating oil seal at the joint of the motor assembly and the speed reduction assembly is added, so that the problem that impurities are easily introduced into the gap between the motor assembly and the speed reduction assembly, the floating oil seal is abraded and corroded, and the speed reduction assembly is damaged or leaks oil is solved.

This invention discloses an intelligent, efficient, and low-damage garlic scape harvester, comprising a walking base on which a divider, a pre-processing mechanism, a clamping and conveying mechanism, and a storage bin are mounted. The pre-processing mechanism includes a needle holder, needles, and a pushing mechanism, as well as a strip plate arranged parallel to the needle holder, with through holes corresponding to each needle. A guide mechanism and a spring are provided between the strip plate and the needle holder, the spring causing the strip plate to tend to move away from the needle holder. The pre-processing mechanism also includes a holding block and a driving component, the holding block being able to enter or leave the space between the needle holder and the strip plate under the action of the driving component. In this invention, on the one hand, different functional states can be determined according to the characteristics of the garlic scape for needle piercing or clamping operations. On the other hand, it can effectively improve the success rate of needle penetration into the garlic scape, ensuring that the needles can be successfully pulled out of the garlic scape, preventing damage to the garlic scape and leaves due to untimely needle removal.

The utility model belongs to the technical field of gypsum plaster boards, and discloses a conveying platform of a gypsum plaster board discharging machine, which comprises a first supporting piece, a second supporting piece is arranged on one side of the first supporting piece, a built-in motor is arranged on the inner side of the first supporting piece, and a first turn-over assembly and a second turn-over assembly are arranged between the first supporting piece and the second supporting piece. The first turn-over assembly and the second turn-over assembly are symmetrical in structure, the second turn-over assembly comprises a first supporting plate arranged on the inner side of a second supporting piece, a second supporting plate is arranged on the inner side of the second supporting piece, and the first supporting plate and the second supporting plate are the same in structure; according to the turnover device for the gypsum plaster board, the gypsum plaster board can be turned over conveniently, impact force borne by the gypsum plaster board is reduced during turnover, and therefore the gypsum plaster board is prevented from being cracked or damaged, and the falling distance of the gypsum plaster board is shortened by attaching the first turnover assembly to the second turnover assembly; and the impact force borne by the gypsum plaster board during turning is reduced through the buffer blocks.

The utility model discloses a single -edged door structure, including door board, decorative board, the fastener and the card seat at door board side edge, decorative board is attached to the front of door board, and the card seat includes the transverse board and the bottom plate of setting at the transverse board lower surface, and the transical groove is formed between the transverse board lower surface, the bottom plate, and the card seat is clamped in the side of door board, decorative board and is pressed together on the door board through the transical groove, and the fastener is from the bottom plate and is carried out the thread connection with the side of door board. The card seat is detachably installed at the door board through the fastener and presses the decorative board from outside to inside, can be convenient to remove the card seat from the door board under the condition of not changing the appearance of door board, and replaces the decorative board, and the use is convenient, when the card seat is fixed in the door board side edge through the fastener, can effectively adjust the assembly gap, angle cooperation details etc. between the card seat and the decorative board, avoid scratching the decorative board or the misplacement problem, improve the adhesion of the card seat package in the decorative board, the door board place.
