The utility model relates to the field of tray feeding and discharging, especially to a tray supply conveying system, which comprises an automatic stacker, a chain conveyor, a light-load tray moving machine, a stacking position cylinder line, a buffer cylinder line I and a buffer cylinder line II. The automatic stacker is used for storing tray stacks and feeding the tray from the bottom to the chain conveyor. The chain conveyor is used for conveying the tray to the light-load tray moving machine. The light-load tray moving machine is used for receiving the tray conveyed by the chain conveyor, lifting the tray to the level of the stacking position cylinder line and conveying the tray to the stacking position cylinder line. The stacking position cylinder line detects whether there is a tray above and whether the tray is full of goods, and conveys the tray to the buffer cylinder line I after the tray is full of goods. The utility model can ensure the stable upward taking out of the tray, realize the uninterrupted conveying of the tray during the operation process, improve the work efficiency, realize the integration of the automatic production line and improve the automatic production level.

The invention discloses a soil conservation device applied to an agricultural photoelectric station and a conservation method, and relates to the technical field of water and soil conservation. The soil conservation device comprises a water collection mechanism and a buffer unit, and the detachable water collection mechanism is arranged at the lower end of a photovoltaic panel and the buffer unit is arranged on the soil surface; rainwater originally dripping along the lower edge of the photovoltaic panel in a concentrated mode can be effectively collected and dispersed, scouring and erosion to soil are remarkably reduced, and the surface structure of cultivated land is protected. According to the device, part of rainwater is guided into the soil below the photovoltaic panel through the recharge channel, the problem of drought under the panel caused by shielding is relieved, and the uniformity of soil moisture distribution is improved. The device is simple in structure and convenient to install and maintain, and the agricultural photoelectric station does not need to be transformed. The conservation method comprises the steps of parameter setting, installation and operation, external energy is not needed, maintenance is easy and convenient, the soil structure is effectively conserved, the cultivated land quality is improved, and meanwhile engineering feasibility and economical efficiency are achieved.

The utility model discloses an adjustable one-time forming concrete stepping pouring mold. Comprising a telescopic device, a fixed side plate, a splicable side plate, an adjustable arched device and a splicable telescopic screw rod. According to the adjustable one-time forming concrete stepping pouring mold, sliding, stretching and retracting of the structure are achieved in the modes of telescopic screws, clamping grooves, sliding rails and the like, fixing is conducted through bayonets, plug pins and other devices, and on-site rapid assembling is achieved. The mold can adapt to casting forming of playground annular runway type concrete stepping stones with different lengths, widths, arch sizes and intervals, the construction procedure can be simplified and recycled, a series of tedious and complex procedures such as on-site manufacturing, assembling and supporting of constructors are reduced, and the working efficiency of the constructors is improved.

The utility model relates to the technical field of watchbands, in particular to a watchband with a double-layer surface and a three-dimensional core, which comprises a watchband main body and clamping needles arranged on the watchband main body, the watchband main body is provided with a sponge layer and a sandwich screen cloth layer wrapping the sponge layer, the sandwich screen cloth layer is of a long-strip-shaped structure, and the clamping needles are arranged on the watchband main body. The sandwich screen cloth layer comprises a mesh surface layer, a canvas layer and a monofilament connecting layer for connecting the mesh surface layer and the canvas layer, the sandwich screen cloth layer is folded and sewed, the sponge layer is wrapped by the folded and sewed sandwich screen cloth layer, and the canvas layer is arranged to be in direct butt joint with the sponge layer; a shaft hole is formed in the folded line position of the sandwich screen cloth layer through sewing so as to be connected with a clamping needle; according to the watchband with the 3D pressing effect, the sponge layer serves as an inner layer, the sandwich screen cloth layer wraps the sponge layer, the three-dimensional structure of the double-layer surface and the three-dimensional core is utilized, and breathability and supporting strength are both considered.
