The invention relates to a device for reducing the spring rate of backfilled and sprayed concrete. The device comprises a PVC endurant plate, three rails and six powerful electromagnets all arranged on a steel arch frame; the rails are connected with the powerful electromagnets; and the PVC endurant plate, the three rails and the six powerful electromagnets are cooperated to form a sealing cavity.According to the device, through additionally arranging the combined structure of the PVC endurant plate, the three rails and the six powerful electromagnets, and through the cooperative action of the PVC endurant plate, the three rails and the six powerful electromagnets, the sealing cavity is formed, so that during specific construction, a relatively closed environment is created for the ejected concrete mixture, ejecting rebound material is automatically collected in the sealing environment, and ejection forming is carried out on the concrete mixture in the sealing environment to effectively reduce the spring rate of the backfilled and sprayed concrete.

The invention discloses a portable detector for an AC charging pile, which comprises a box body, a box cover is hinged on the box body through a connecting piece, a detector body is arranged in the box body, a groove is opened on the detector body, and a groove is arranged in the groove The display screen is fixedly connected with a protective assembly matching the display screen, and the inner bottom wall of the box is fixedly connected with a shock absorber. In the present invention, by adding a combined structure of the protective assembly and the shock absorber, the protective assembly The setting, when the box cover is closed, will make the protective component match the groove and the display screen, so that it can not only play a dust-proof effect, but also play a role in protecting the display screen under the action of the protective component. The setting of the shock absorbing device can play a very good shock absorbing effect, so that when the vibration occurs, the effect of the shock absorbing device will reduce the vibration effect, and avoid excessive vibration of the electrical components inside the detector body, thereby causing damage.

The invention relates to an air-drying device for chili seeds and aims to solve the problems that a conventional air-drying basket is placed on a support rack and is often blown over by wind, and meanwhile the air-drying area of the conventional air-drying device cannot be increased in a vertical direction. A rotating rod is rotationally arranged inside a rotating hole formed in a fixing plate; both ends of the rotating rod are respectively rotationally arranged on the lower plate surface of an upper transverse plate and the upper plate surface of a lower transverse plate; both the upper transverse plate and the lower transverse plate are fixedly arranged on the side wall of a lower air-drying shelf; a second magnet is embedded into the side wall of one end, far away from the rotating rod,of the fixing plate; a first magnet is arranged on the second magnet in a sucking manner; and the first magnet is embedded into the side wall of the lower air-drying shelf. According to the air-drying device, a combined structure of a first fixing part and a second fixing part is added, and due to arrangement of the combined structure, an air-drying basket can be stably placed on air-drying shelves, the situation that the air-drying basket is blown over by wind is avoided, and thus the problem that time and labor are consumed to settle scattered chili seeds later can be avoided.
