Second board bodies are hinged to two sides of the first board body. A warning sign and more than one ducting hole are provided on and in the surface of the first board body. More than one ducting hole is provided in the surface of each second board body. An elastic element is arranged between each second board body and the first board body. The first board body is connected to the supporting post by means of a connecting piece. The novel convenient special signboard for express way is simple in structure, capable of attracting attention better in night, and better indicative; and the signboard has excellent wind resistance, and thus is not prone to be blown away by wind and not prone to cause traffic accidents; and the signboard is convenient to demount and repair.

The invention discloses an ultra-infrared air-floating shallow-layer fluidized reactor, which is a novel fluidized reactor for ZIF pyrolysis. Including the main air intake pipe, the air intake pipe under the porcelain boat, the tube furnace, the collection target, the upper cover of the porcelain boat, the gas exchange hole, the main body of the porcelain boat, the wire mesh, the magnetic ball, the air inlet under the porcelain boat, the air outlet pipe, and the ultra-infrared control device and ultra-infrared pulse emission device; the invention is based on the traditional tube furnace reactor, and designs a method of applying shallow fluidization technology and ultra-infrared magnetic levitation technology to solve the problem of uneven heating caused by agglomeration of ferromagnetic ZIF materials during the pyrolysis process To solve the problem, improve the porcelain boat and introduce gas exchange holes to solve the problem that the powder is easily blown away by the protective gas. At the same time, adding a collection target can collect the zinc volatilized during the pyrolysis of ZIF‑8. The device has a simple structure and can solve various problems in the pyrolysis process.

The invention relates to a method of preventing and treating a weed, orobanche coerulescens, through an agricultural bio-degradable mulching film combined with biocontrol bacteria. The method includes the steps of preparing a fermentation liquid of pythium aphanidermatum, performing centrifugal, elution on a column and concentration to the fermentation liquid to prepare a pythium aphanidermatum powder, preparing the bio-degradable mulching film containing the pythium aphanidermatum powder, and paving the mulching film in the field on which crops and the orobanche coerulescens are grown. The method is excellent in preventing and treating effects, avoids pollution caused by chemical agents through the bio-controlling technology, and is more durable in the preventing and treating effects since the synergistic effects of the bio-degradable mulching film is combined.

The invention provides a post-processing device for environmentally friendly fabrics, which includes a box body, a traction system arranged at one end of the box body, and a sizing system arranged at the other end of the box body. The two ends of the box body are respectively provided with feeding ports and The outlet also includes: pre-drying system, carding system, drying system and heating system. Through pre-drying treatment, 70‑80% of the water in the finished fabric can be quickly removed to improve subsequent flexibility. The system combs the fibers on the surface of the fabric into a certain regular arrangement, combined with the drying system to perform secondary treatment on the arranged fibers, arranges the fibers on the surface of the fabric according to a certain rule, and improves the flexibility and wear resistance of the fabric. Improve the processability of subsequent fabrics.

The application relates to a garden plant maintenance device, which belongs to the technical field of plant maintenance. It comprises a base ring arranged around the seedlings and a support assembly arranged on the base ring and used to support the seedlings, the lower end of the base ring is inserted into the ground, the upper end protrudes from the ground, one end of the support assembly is connected with the base ring, and the other end is in contact with the seedlings. catch. When the curing device is in use, the base ring is sleeved outside the seedlings, and the lower end of the base ring is embedded in the soil on the ground, so that the base ring is not easily blown away by the wind, and the support assembly is connected to the base ring, so that the support assembly is not easily blown away by the wind. Walk.

The invention discloses a carton carrying vehicle convenient to load and unload. The carrying vehicle comprises a bottom plate, and a plurality of wheels are arranged on the bottom face of the bottom plate; a holding portion is fixed to the outer wall of a baffle on the rear side of the bottom plate, and a groove is formed in the middle of the bottom plate; the front side wall of the bottom plate is an arc-shaped side wall, and the middle of the front side wall of the bottom plate is a middle annular side wall; the middle arc-shaped side wall is communicated with the front portion of the groove, and a limiting protruding portion is arranged in the middle of the groove, and two sliding grooves are formed between the limiting protruding portion and the left side wall of the groove and between the limiting protruding portion and the right side wall of the groove; the bottom face of a carrying box is provided with two sliding strips, and the two sliding strips are inserted into the sliding grooves in a sleeved manner; the bottom face of the carrying box is pressed on the bottom plate, and an auxiliary block is hinged to the front end of the back face of the bottom plate; the auxiliary block is pressed on the ground, and the front portion of the auxiliary block is an inclined wall face; and permanent magnetic iron blocks are arranged on the two sides of the arc-shaped side wall, and correspond to the auxiliary blocks. An unfolded paper board of a carton can be carried, and the auxiliary blocks arranged on the carton carrying vehicle can conveniently push the carrying carbon to the bottom plate.

The invention relates to preparation of matrix particles capable of producing degradable mulching films, in particular to alloy matrix particles for preparing the degradable mulching films. The alloy matrix particles for preparing the degradable mulching films comprises the following components in percentage by weight: 0.01 to 0.03 percent of tert-butyl peroxy isopropyl benzene, 1.50 to 2.25 percent of fumaric acid, 4.50 to 5.60 percent of microcrystalline wax, 3.60 to 5.40 percent of polyethylene wax, 3.00 to 4.20 percent of MG70, 9.00 to 13.0 percent of N210 and 68 to 80 percent of corn starch. The alloy matrix particles for preparing the degradable mulching films have the advantages that: the alloy matrix particles can be restructured with PE structures to form a network bridge, so the prepared mulching films can be degraded quite uniformly; the problem of balancing the water tolerance and the hydrophilicity is solved, so the prepared mulching films can be attached to the ground surface, are difficult to blow away by wind, and have better function when used as the mulching films; and the mulching films can be blown to the thickness of 0.005mm and have small specific gravity, so the same amount of raw materials can produce more mulching films.
