The utility model provides a kind of Chinese torreya grandis oil mixing device, belong to Chinese torreya grandis oil manufacturing technical field;Chinese torreya grandis oil mixing device includes: mounting bracket, mixing tank, first rotating shaft, first blade, second rotating shaft, second blade, mounting ring, scraping ring, lifting mechanism, lifting plate, connecting rod and discharge port;By lifting mechanism and lifting plate are connected, the one end of multiple connecting rods is connected with lifting plate, and the other end of multiple connecting rods is simultaneously connected with scraping ring, to realize when lifting mechanism starts, lifting mechanism can drive lifting plate and multiple connecting rods to move up and down, and then realize multiple connecting rods can drive scraping ring to move up and down;By scraping ring is sleeved in the outside of mounting ring, and scraping ring is attached with the inner wall of mixing tank, to realize mounting ring can drive scraping ring to move up and down along the inner wall of mixing tank, so that scraping ring can scrape the raw materials adhered to the inner wall of mixing tank, to improve the utilization of raw materials.

The utility model relates to the technical field of petroleum drilling platforms, in particular to a drill bit loading and unloading bearing table for petroleum drilling. The drill bit loading and unloading bearing table for petroleum drilling comprises a bearing unit, a rotating unit and a lifting unit, the bearing unit is used for bearing a drill bit, and the rotating unit can make the bearing unit rotate around the axis of the rotating unit; the lifting unit can drive the bearing unit on the rotating unit to do lifting motion so that a drill bit on the bearing unit can be in butt joint with a drill column on the oil drilling platform. Therefore, an operator only needs to lift a drill bit to the bearing unit, and when the drill bit is screwed on and connected, the hoisted drill column is lowered until the lower end of the drill column is in butt joint with the drill bit on the bearing unit, and the operator does not need to continuously keep the state of lifting the drill bit; therefore, threaded connection of the drill bit and the drill column can be achieved, time and labor are saved, the drill bit falling safety risk is reduced, and installation efficiency is improved.

The utility model provides a municipal road surface grooving device, and belongs to the technical field of road surface grooving. The municipal road surface grooving device comprises a bottom plate, an adjusting mechanism, a translation table, a lifting mechanism, a lifting plate, a first supporting plate, a first rotating shaft, a cutting blade, a second supporting plate, a second rotating shaft, a ground breaking wheel and universal rolling wheels. The two cutting blades and the soil breaking wheel are located on the outer side of the bottom plate so that the cutting blades and the soil breaking wheel can be opposite to a groove to be formed, the grooving precision of a product can be improved, and the use experience of the product can also be improved. The adjusting mechanism is installed on the bottom plate and connected with the translation table, so that the adjusting mechanism can drive the translation table, the two cutting blades and the soil breaking wheel to move, it is ensured that the cutting blades and the soil breaking wheel are opposite to a groove to be formed, and the product grooving precision is further improved.
