The invention discloses a wallboard assembling robot which comprises a vehicle frame (1). A lifting frame (2) is arranged in a guide rail A (7) of the vehicle frame (1), and a piston rod of a lifting hydraulic cylinder (9) is fixedly connected with the lifting frame (2). A sliding frame (3) is arranged in a guide rail B (10) of the lifting frame (2), and a lifting chain A (13) which is fixedly connected to a stand column (6) is fixedly connected with the sliding frame (3) by winding around a guiding chain wheel A (12) of the lifting frame (2). A lifting seat (4) is arranged in a guide rail C (14) of the sliding frame (3) in a sliding mode, and a lifting chain B (16) which is fixedly connected with the stand column (6) is fixedly connected with the lifting seat (4) by winding around a guiding chain wheel B (15) of the sliding frame (3). A hanging basket (5) is connected with the lifting seat (4). The wallboard assembling robot has the advantages of being capable of improving installation efficiency and degree of labor safety and reducing labor intensity, simple in structure, easy to maintain, convenient to operate, safe, reliable, and capable of achieving high lifting.

The invention discloses a semiochemical compound color plate and a preparation method thereof. The semiochemical compound color plate comprises a substrate provided with colors, wherein the surface of the substrate is coated with insect gluing viscose, and the insect gluing viscose is formed by mixing sticky mucilage glue and appropriate semiochemicals according to a certain proportion. The synergistic action of the semiochemicals and visual information to food taking, oviposition and other actions of insects is utilized to optimize the color wavelength of each insect, semiochemical components are combined with a viscose plastic (PP (polypropylene), PVC (polyvinyl chloride) or PE (polyethylene)) or paper color plate to prepare the semiochemical compound color plate, the short distance ofthe visual information is overcome, the trapping efficiency and the trapping range are greatly increased, and male and female injurious insects can be trapped. The semiochemical compound color plate can be used for trapping aphids, aleyrodids, liriomyza sativae, diamond back moths, empoasca vitis, aleurocanthus spiniferus, thrips and various other hemiptera, homoptera, lepidoptera and diptera injurious insects, particularly insects hidden under leaf surfaces or in the shadow. The utilization efficiency of the color plate is greatly improved, and the dosage of the color plate is reduced so as to reduce the cost.

The invention discloses a technological method for producing copper rice grains by recovering waste wires and cables based on an improvement of the prior production mode that the waste wires and cables recover copper raw materials. The technological method has low cost, small energy consumption, less discharge and no waste pollution, meets the requirement of circular economy development, and can obtain a copper rice grain product the purity of which reaches 99.9 percent. The technological process comprises the steps of classification inspection, loading, primary crushing, secondary crushing, and vibration separation; the angle of a vibration sieve is adjusted according to the content of copper and the wire diameter, and the copper rice grains and plastic are subjected to optional separation through vibration sieving; a material from a mixed material port flows into an air suction pipe, and is sent for secondary crushing through a circulating air pipe; the air suction pipe above the vibration sieve sucks plastic fibers and other dust in the space of the vibration sieve to a dust collector for treatment; the qualified copper rice grains obtained at a copper outlet flow into a packing bag; and the finished product inspection is performed, namely the obtained copper rice grains enter a warehouse through the inspection.

The invention relates to a method for preparing flocculant, fertilizer and methane with sludge containing algae, which relates to a process for turning the sludge containing algae into resources. First, a hydrothermal oxidation technology is adopted to separate organic matter and inorganic matter in the sludge containing algae under the conditions of 150 to 180DEG C of temperature and 0.8 to 1MPaof pressure to obtain brown organic residual waste liquid and solid sludge containing aluminum and iron inorganic matter; and then the solid sludge is dried, ground and screened; hydrochloric acid isadded into screen underflow to react for 1 to 2h at 90 to 100DEG C, and stays still; the pH value of a supernatant is regulated to 2.5 to 4, and the supernatant is cured for 12h at 50 to 60DEG C to obtain a PAC iron liquid product; the PAC iron liquid product is dried, and a PAC iron solid product is obtained; and the pH value of the organic residual waste liquid is regulated to 8 to 9, and the organic residual waste liquid enters an upflow anaerobic sludge bed reactor to react for 24h at 35DEG C to obtain granular organic fertilizer and combustible gas with 65 percent of methane content. Themethod for preparing flocculant, fertilizer and methane with algae-containing sludge has the advantages of simple process, low cost and high economic and social benefit, and can be widely applicable to the zero algae-containing sludge discharge and the clean production of sewage plants which treat lake sewage polluted by algae.
