Description

A safe attemperator for warmly increasing watermelon big-arch shelter Technical Field The utility model relates to the technical field of watermelon planting production, in particular to a safe temperature regulating device for heating a watermelon greenhouse. Background In order to improve economic benefit, early spring watermelon planting time tends to advance year by year, but frequent reverse spring cold and snowfall weather become main constraint factors for early spring watermelon production. Under the low-temperature environment, watermelon plants are easy to suffer from cold injury and freeze injury, so that root system development is blocked, growth process is delayed, and problems of stiff seedlings, poor pollination and the like occur. The climate stress seriously affects the yield formation and flavor quality of watermelons, and limits the improvement of industrial benefits. The existing greenhouse lacks a temperature light adjusting and controlling facility, so that the production of watermelons is greatly limited. The greenhouse has simple structure, relatively reduced cost and wide application in production, while the high-end equipment in the intelligent greenhouse is not applicable to greenhouse facilities and has higher cost; When the greenhouse temperature-increasing block with lower cost is adopted, the condition that sparks leak and burn to the mulching film and the greenhouse film exists, and the risk coefficient is higher. Accordingly, in view of the above, research and improvement are made on the existing structure and the defects, and a safe temperature adjusting device for heating the watermelon greenhouse is provided so as to achieve the purpose of higher practical value. Disclosure of utility model The utility model aims to provide a safe temperature regulating device for heating a watermelon greenhouse, which aims to solve the problems in the background technology. The safe temperature regulating device for the watermelon greenhouse temperature increase comprises a working box, a transmission heat insulation box and an ash filter assembly, wherein a feeding transportation channel is arranged at the top of one side of the working box, greenhouse temperature increasing blocks are arranged above the feeding transportation channel, one side of the feeding transportation channel is vertically connected with the transmission heat insulation box, the transmission channel is arranged in the transmission heat insulation box, the tail end of the transmission channel is provided with a discharging slope, the bottom of the discharging slope is externally connected with a recovery drawer, the ash filter assembly is erected above the recovery drawer, the ash filter assembly comprises an inclined filter grid and a straight filter grid, and the other end of the inclined filter grid is provided with the straight filter grid; The inclined filter grid is matched with the blanking slope, and a temperature monitor is arranged at the joint of the corner of the transmission heat insulation box and the corner of the feeding transportation channel; the movable plugging partition board is embedded in the channel groove of the transmission channel, and an open slot is formed in the blanking slope of the transmission channel; A side electric push rod is arranged on one side surface of the feeding transportation channel, and a telescopic rod is horizontally arranged on the side electric push rod; The top of the upper cover plate of the recovery drawer is provided with a gas supply pipe, and the inner parts of a plurality of groups of the gas supply pipes are horizontally provided with metal wire filter screens.
