Agricultural greenhouse defrosting and snow removing device based on gravity action
The invention relates to the field of agricultural greenhouse defrosting and snow removing, and discloses an agricultural greenhouse defrosting and snow removing device based on the gravity action. The tops of supporting columns are fixedly connected with a transverse plate, the outer sides of lead screws are movably connected with snow removing arc plates through connecting bases, the outer sidesof the snow removing arc plates are fixedly connected with scraper blades, the top of the transverse plate is movably connected with a first movable plate, a second movable plate and an installing block, the sides, facing the interior of a greenhouse, of the first movable plate and the second movable plate are provided with pressing plates, a spring and a switch are arranged inside the installingblock, and when metal sheets on the two sides make contact with the switch, the device can be normally started. According to the agricultural greenhouse defrosting and snow removing device based on the gravity action, if too much snow is accumulated on the top of the greenhouse, the spring is compressed under the gravity action, at the moment, the metal sheets on the spring make contact with theswitch, the device is automatically started, the aim of automatic starting according to the gravity is achieved, and the problem of frequent starting of the device caused by unintended touch due to external factors is avoided.
本发明涉及农业大棚除霜雪领域，且公开了一种基于重力作用的农业大棚除霜雪装置，所述支撑柱的顶部固定连接有横板，丝杠的外侧通过连接座活动连接有除雪弧板，除雪弧板的外侧固定连接有刮板，横板的顶部分别活动连接第一活动板、第二活动板和安装块，第一活动板和第二活动板朝向大棚内的一侧安装有压板，安装块的内部分别设置有弹簧和开关，当两侧的金属片均与开关接触时，装置才能正常启动。该基于重力作用的农业大棚除霜雪装置，若大棚顶部的积雪过多，在重力作用下，压缩弹簧，此时弹簧上的金属片均与开关接触，装置自动启动，达到了根据重力自动启动目的，且避免了外界因素误触造成装置频繁启动的问题。
