The invention discloses a production technology for a circular-truncated-cone-shaped elevation concrete block for a floor slab. The production technology comprises the steps of the preparing stage, the pouring stage, vibration forming, connecting piece setting, forming form removal and the like. According to the production technology for the circular-truncated-cone-shaped elevation concrete block for the floor slab, vibration waves can be formed between ring plates and clamping plates under the knocking action, the ring plates are vibrated through the vibration waves, demoulding is facilitated, in other words, an operator can finish demoulding with small knocking force, labor force input is reduced, and the demoulding efficiency is greatly improved; and meanwhile, knocking on a die is reduced, and accordingly the service life of the die is prolonged; the distance between connecting columns and wedge-shaped blocks is 81%-84% of the length of ring plate bevels; and resonance is most easily generated between the ring plates and between the ring plates and the clamping plates, and the demoulding efficiency is the highest in the resonance state. Equal-height blocks manufactured through the method can be used for wood templates and steel templates, corresponding technologies can be adopted for the two different templates, and high universality is achieved; and the demoulding operation is conducted according to the set sequence, and the superior product rate of products can be increased to 90% or above.

The invention discloses a manufacturing method of hot-work die steel. The method is characterized by including the steps: blank forging, annealing, mechanical roughening, finish machining forming, quenching, high-temperature tempering, fitter trimming, polishing, mold assembling and mold testing; and the hot-work die steel is one of 5H12, H13 and 8418. According to the method, water-bath cyclic quenching treatment is adopted to transform a massive lamellar structure of the steel into a uniform and fine structure, and the steel is not liable to break. The effects of rapid heating and cyclic treatment are fully utilized, heating is rapidly performed, a large number of austenite crystal nuclei are generated, and fine grains appear and are obtained; and the faster the process is carried out, the greater the temperature difference is, and the better the obtained refining effect is.

The invention relates to a cut tobacco recovery device and a waste cigarette crushing mechanism thereof. The waste cigarette crushing mechanism comprises a shell, a rotary shaft and a soft rod. The soft rod comprises a rigid base body and a flexible covering layer covering the surface of the base body. One end of the soft rod is installed on the rotary shaft, and the rotary shaft can drive the soft rod to rotate in a containing cavity of the shell. When cut tobacco is recovered, waste cigarettes enter the shell through a feed port, and the rotary shaft rotates to drive the soft rod to beat the waste cigarettes in the containing cavity. Due to the fact that the surface of the soft rod is provided with the flexible covering layer, the soft rod and the waste cigarettes are in flexible contact. The waste cigarettes are crushed through the soft rod by means of friction and vibration. Thus, compared with a cutting or grinding mode adopted for traditional equipment, the cut tobacco is not likely to be broken when the waste cigarettes are crushed through the crushing mechanism, the integrity of the cut tobacco can be better kept, and then the finally recovered cut tobacco is good in integrity through the cut tobacco recovery device.

The invention discloses a plant ecological building curtain wall for a bottom-layer building, and belongs to the field of ecological building curtain walls. According to the scheme, gas generated through pheromone volatilization can be discharged to the position of landscape plants along an insect inlet channel, insects in the landscape plants are attracted to crawl to the position where an insect catching bottle is located through pheromone, at the moment, under the action of the self gravity of the insects and a counter weight part, rubber fan blades easily deform downwards as shown in a figure 8, part of the insects easily fall off from gaps among the multiple rubber fan blades and fall on the pheromone, and kinetic energy generated by falling directly penetrates through the pheromone and a bearing net and falls into distilled water, so that the insects are captured; part of insects open wings to fly in the falling process, do not directly fall to the upper side of the pheromone but slowly fall, but when the insects want to leave the insect catching bottle, the insects are difficult to jack up the rubber fan blades by means of own force, and the insects are difficult to escape from the insect catching bottle.
