Automatic coal feeding device

Abstract

The invention discloses an automatic coal feeding device, comprising: a barrel body for accommodating coal materials, the barrel body including a barrel wall and a bottom plate, and the bottom plate is rotated downward to open for coal adding operation; a control device includes a timing control mechanism and a limiter; and a locking device, including: a locking member arranged at the bottom of the barrel to lock the bottom plate in a non-feeding state; and a transmission rod arranged on the periphery of the barrel, The limit end of the transmission rod is limited by the limit member, and the transmission end of the transmission rod is connected to the locking member; when the set coaling time arrives, the timing control mechanism triggers the limit The position member releases the limit on the limit end, and the transmission rod rotates to release the lock of the locking member to the bottom plate. The invention has simple operation and low cost, and can automatically complete single or multiple automatic coal adding operations.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an automatic coal adding device. Background technique [0002] Boilers are an important living equipment. For remote areas, or cold areas without central heating, household boilers can provide hot water while heating, and the heat of the boiler can be used for cooking. [0003] When the boiler is running at night, it needs to carry out coal feeding operation. In the prior art, people usually need to get up at night to manually add coal, which brings inconvenience to people's lives. And when coal needs to be added many times at night, it is even more inconvenient. If you fill up the coal before going to bed, on the one hand, the boiler needs to increase the space for temporarily storing coal, on the other hand, it also reduces the utilization rate of coal, reduces thermal efficiency, increases expenditure, and is not conducive to environmental protection. In addition, eve...
