A liquid spray unit which can impart liquid (treating liquid, medicine, or the like) surely to a traveling body even in a high speed paper making machine. The liquid spray unit for spraying liquid to a traveling body comprises a spray tube provided with a nozzle for spraying liquid, and an air box provided with an opening for jetting an air flow, wherein the spray tube and the air box are arranged such that the air flow is jetted from the air jet opening toward the liquid sprayed from the spray nozzle and the sprayed liquid can be blown to the traveling body after being accelerated by the air flow. The liquid can be sprayed more effectively to the traveling body by making compact the unit depending on the quantity of liquid being imparted or the inner space of a paper making machine, or the like, or by employing a unit of a type of reciprocating a single nozzle.

The invention discloses a method for repairing heavy metal contaminated soil through biochemical resources. The method comprises three processes of insecticide spraying, earthworm enrichment repairing and microbiological degradation. The insecticide used in the insecticide spraying process comprises the following materials of, by mass, 280-320 parts of organic fertilizers, 28-32 parts of microorganism bacterium agents, 0.05-0.1 part of pyrethrum, 0.03-0.09 part of derris and 0.02-0.06 part of agritol powder. According to the method for repairing the heavy metal contaminated soil through the biochemical resource, not only can fertilizer efficiency of soil be improved but also pests in the soil and on the surface of earth are killed, and moreover the microbiological degradation process is added, so that the effect is remarkable and operation is simple.

The invention discloses a method for remedying heavy metal contaminated soil. The method comprises the three processes of insecticide spraying, earthworm enrichment and remediation and microbial decomposition, wherein an insecticide in the insecticide spraying process is prepared from the following materials in parts by weight: 280-320 parts of organic fertilizers, 28-32 parts of microbial agent, 0.05-0.1 part of pyrethrum, 0.03-0.09 part of derris and 0.02-0.06 part of bacillus thuringiensis powder. The method for remedying heavy metal contaminated soil not only can achieve the effect of improving the fertilizer efficiency of the soil but also can achieve the effect of killing pests in the soil and on the earth surface, has the advantage that the microbial decomposition process is also added, has obvious effects and is simple to operate.

The invention relates to the technical field of forestry equipment, in particular to a municipal tree protecting paint brushing device. The municipal tree protecting paint brushing device comprises abase; a storage battery, a rotating device, a material pump, a material storage tank and a push rod are mounted on the upper surface of the base in sequence from left to right; a discharging pipe is connected between the material storage tank and a material inlet of the material pump; a first electric telescopic rod is rotationally connected to one end of a moving rod through a pin shaft; a connecting rod is fixedly mounted on one side of a height adjusting device; a U-shaped plate is fixedly mounted at one end of the connecting rod; an output end of a second motor extends into the groove, anda first gear is connected to the output end of the second motor; and racks engaged with the first gear are connected to one opposite ends of two slide blocks. According to the municipal tree protecting paint brushing device, the structure is simple, the use is convenient, materials can be sprayed to trees without a dead corner, the working intensity of working personnel is greatly reduced, the material spraying of the trees is accelerated, the working personnel can also work under a safe environment, the municipal tree protecting paint brushing device is safe and reliable, the practicabilityis high, and the municipal tree protecting paint brushing device is worth of being popularized.
