1. An easy-to-clean visual grain monitoring device, comprising a housing, wherein:
a circuit board is provided within the housing and is connected with a monitoring unit;
an insect collecting pipe, which is provided within the housing, comprises multiple first entrances;
the housing comprises multiple second entrances which are corresponding to the first entrances respectively;
an execution element, which is installed on a base, is connected with a lower end of the insect collecting pipe for driving the insect collecting pipe to move up and down;
an insect leaking passage, which is provided at an upper end of the base, extends downwards along a side wall of the base;
a tail end of the insect leaking passage has a first insect leaking hole for discharging pests, the housing has a second insect leaking hole in a position corresponding to the first insect leaking hole, and the lower end of the insect collecting pipe has a third insect leaking hole staggered with the insect leaking passage, wherein an upper end and a lower end of the housing has two openings respectively, two end plugs are provided at the upper and lower ends of the housing for sealing and are connected with the housing through two location pins respectively; the two end plugs have two connecting holes respectively; the monitoring unit comprises a camera, a temperature sensor and a humidity sensor; a fill-in light is provided beside the camera; the insect collecting pipe is provided at an area which is illuminated by the camera,
wherein the execution element is installed on the base; a connecting rod, which is provided at the lower end of the insect collecting pipe near the base, is connected with an output end of the execution element; one end of the base near the insect collecting pipe has a mounting hole; the connecting rod and the output end of the execution element define a whole which is able to slide within the mounting hole, wherein the insect leaking passage, which is provided outside the mounting hole, extends downwards along the side wall of the base; the tail end of the insect leaking passage has the first insect leaking hole for discharging the pests; the housing has the second insect leaking hole in the position corresponding to the first insect leaking hole; the lower end of the insect collecting pipe has the third insect leaking hole staggered with the insect leaking passage; when the lower end of the insect collecting pipe is completely fitted with the base, the third insect leaking hole is blocked by the base, and at this time, the lower end of the insect collecting pipe and the base form a complete bottom surface, the insect leaking passage is blocked; when the execution element drives the insect collecting pipe to move upwards, the lower end of the insect collecting pipe is away from the base, so that a gap is formed between the insect collecting pipe and the base; and at the same time, the insect leaking passage is unblocked, the third insect leaking hole is unblocked.
