4results about How to "Effectively cut off" patented technology

The invention relates to the technical field of granulators, in particular to a traditional Chinese medicinal material processing and granulating device which comprises a base, a grinding knife and a pressing blade which are rotationally arranged on the base, and a driving part which is arranged in the base, is connected with the grinding knife and the pressing blade and is used for driving the grinding knife and the pressing blade to rotate relatively. According to the device, materials are cut off through the arc-shaped scraper, so that particles are regular in shape; the movable pipe extends the extrusion path, particles are more compact and firmer, the granulation quality and uniformity are integrally improved, meanwhile, the position of the movable pipe can be adjusted, the length of the extrusion path of materials is changed, various production requirements are met, meanwhile, the arc-shaped scraper is attached to the surface of the movable pipe, it is ensured that the materials can be effectively cut off in different working states, and the production efficiency is improved. And internal and external co-extrusion is realized, so that the granulation effect is further optimized, and the production efficiency and the product quality are improved.

This utility model relates to the field of chrysanthemum planting technology, specifically a seedling lifting and fixing mechanism for chrysanthemum planting. It includes a seedling lifting support frame, with a rectangular frame fixedly connected to the inner wall of the support frame. It also includes a seedling lifting mechanism disposed on the outer wall of the support frame. The lifting mechanism includes a sliding plate slidably connected to the inner wall of the rectangular frame. A chrysanthemum seedling through-hole is formed on the top outer wall of the sliding plate. Fixing rods are fixedly connected to the two outer walls of the top of the sliding plate, and handles are fixedly connected to the top outer walls of the fixing rods. Inclined grooves are formed on the two outer walls of the top of the support frame. The insert plates on both sides of this utility model allow for a longer path for soil cutting, thus more effectively cutting the soil around the chrysanthemum roots. The required depth of soil insertion is low, making seedling lifting easier. After lifting, the chrysanthemum seedling and soil can be completely pushed out, improving the seedling lifting efficiency of the chrysanthemum planting seedling lifting and fixing mechanism.

The utility model discloses a switch assembly, machining equipment and a machining system, the switch assembly is suitable for the machining equipment, and the machining equipment comprises a first power interface, a second power interface, a 3D printing head and a laser machining head detachably connected with the 3D printing head; wherein the switch assembly is provided with a control switch and a first communication interface, and the control switch is connected between the first power interface and the laser processing head. The first communication interface is used for plugging a connector, the first communication interface is also used for connecting a second power supply interface, and the voltage at the second power supply interface is lower than that at the first power supply interface. The connector can serve as a safety key for starting the laser machining head, and whether the laser machining head can be started or not is recognized by detecting the connector inserted into the first communication interface. The control switch can control connection and disconnection between the first power interface and the laser processing head. And the safety of the processing equipment during production and processing is improved through double guarantee of the connector and the control switch.

The utility model relates to a weed removing device in a corn planting field, and belongs to the technical field of agricultural machinery. The device mainly comprises an operating rod, a main control handle, an auxiliary handle, a mounting shell, a protective cover, a cutting assembly, a soil turning claw, a transmission shaft, a motor, a lithium battery and a crushing assembly, the cutting assembly cuts off overground parts of weeds through a rotating disc and cutting blades, soil turning claws penetrate into soil to scarify roots, and the smashing assembly achieves the multi-layer smashing effect through staggered arrangement of first smashing cutters and second smashing cutters; through the synergistic effect of the cutting assembly and the soil turning claw and the combination of the efficient smashing function of the smashing assembly, the weed harvester not only can effectively cut off the overground part of weeds and smash the overground part of the weeds, but also can go deep into soil to loosen and pick up the root systems of the weeds, so that the roots of the weeds are exposed on the surface of the soil and are smashed through the smashing assembly; the thoroughness of weed removal is remarkably improved, the possibility of weed regeneration is reduced, and adverse effects on normal growth of corn are avoided.
