The invention discloses a red date bag and usage thereof. The red date bag comprises a bag body formed by two pieces of paper; openings are arranged on the bag body and located at two ends of the bag body, wherein the opening at one end is a date string inlet and the opening at the other end is a date string outlet; binding strips are fixed at two sides of the bag body; when the first stage of fruit setting of the red dates is finished, bactericide is sprayed to ensure that later-stage flowers fall off; a date string or branch with better fruit setting is sheathed in the bag body from the opening at one end, the end of the date string or branch extends out from the opening at the other end and the openings at the two ends are respectively tied by using the binding strips; and the bag bodyis adjusted to ensure that the opening at one end is downward. Through the red date bag and the usage thereof, the red date string or branch is bagged to ensure that the red date will not be infectedwith pesticide in the process of growth and prevent the long-term contact between the rainwater and the red date especially in the later stage of the growth of the red date, thereby effectively preventing the fruit cracking phenomenon caused by rain; at the same time, the occurrence of mould diseases are prevented. Proved by two years of field experiment, the growth period of the bagged red date can be prolonged by about 20 days and the control efficiency to the brown blotch, the anthracnose and the fruit cracking phenomenon in the date gardens of China in recent years is higher than 90%. Thepeel of the red date is natural, bright and clean; the appearance is attractive; the maturity is greatly improved; the mouth feel is favorable; the quality of the red date reaches the high-quality standard; and the commodity value is greatly enhanced.

The invention relates to a double-station automatic bridle end sealing mechanism of a steel wire ring. The double-station automatic bridle end sealing mechanism consists of an air cylinder, swinging rods, a linking pin, a connecting rod, a clamp plate body, a reset spring, a reset rod, a cutter, a clamp plate, a clamp plate support frame and an air cylinder box, wherein a screw bolt hole is formed in the upper side of the air cylinder box and is connected with an external supporter; the air cylinder box and the air cylinder form a mechanism power source; the pneumatic device can push the air cylinder to do vertical and reciprocating movement; the air cylinder is connected with the clamp plate support frame; the support frame is driven to do ascending and descending movement; the swinging rods are arranged on the clamp plate support frame; the two swinging rods are connected onto the clamp plate support frame through the linking pin; meanwhile, the linking pin is connected with the reset rod; the reset spring is arranged on the reset rod; the lower side of the clamp plate support frame is fixedly connected with the cutter; the swinging rod is connected with the connecting rod through a pin; the connecting rod and the clamp plate are connected through a pin. The mechanism has the advantages that the ascending and descending of the clamp plate, and the closing of the clamp plate can be realized; the two-freedom movement can be realized; the simultaneous and automatic bridle end sealing can be automatically realized on two steel rings.

The invention discloses a demolding and packaging device for a rubber sealing ring. The demolding and packaging device for the rubber sealing ring comprises a forming unit, a separating unit, a moving unit, a demolding unit, a spraying unit and a packaging unit. The forming unit comprises an upper mold and a lower mold which mutually form a forming cavity; after the upper mold drives the formed rubber sealing ring to be separated from the lower mold under the action of the separating unit, the moving unit moves from the upper part of the lower mold to the upper part of the demolding unit, and the formed rubber sealing ring is separated from the upper mold under the action of the demolding unit; the spraying unit sprays an anti-aging lubricating agent to the demolded rubber sealing ring; and the packaging unit packages the rubber sealing ring sprayed with the lubricating agent.

The invention relates to an in-situ soil column leaching test device and method. The device includes a limit frame, a receiving plate arranged below the limit frame, a liquid reservoir connected to the bottom of the receiving plate, a sampling conduit and a liquid storage The sampling bottle communicated with the bottom of the reservoir, the inflation device used to inflate the liquid reservoir, the exhaust pipe used to discharge the gas in the liquid reservoir and the controller used to control the inflation device. The present invention utilizes "double frames and equal water head infiltration" to constrain the lateral seepage of the leaching solution to obtain a one-dimensional vertical leaching approaching the soil column, greatly reducing the influence of the lateral flow of the solute, and directional collection of the target seepage surface, The in-situ leaching and liquid collection of the target soil column are realized. The specially designed leach solution collection structure of the invention is ingeniously designed, which can effectively avoid the long-term contact between the soil leach solution and the air, facilitates the oxygen-free collection of the leach solution containing reduction-sensitive indicators, and avoids the oxidation and precipitation of the reduction-sensitive indicators. Ensure the authenticity of the collected shower solution composition.
