Description
Technical Field
The invention belongs to the technical field of grain condition detection sampling devices in granary, and mainly relates to a grain condition detection probe. The device is suitable for sampling pests and gas in the granary and detecting the temperature, humidity, sound and image of grains at sampling points.
Background
In grain storage, not only is the damage of pests on grains stored in a bin very large, but also the temperature and the humidity of a grain pile are one of important indexes for judging whether the stored grains are safe, so that the grain pile in the bin needs to be periodically sampled to determine parameters such as the types, the quantity and the states of the pests, and the temperature and the humidity of the grain pile are detected.
The traditional sampling method for insect pests in grain storage adopts a sampling screening method, so that the labor intensity is high, and the accuracy is low; the existing grain pile temperature detection is to detect the grain temperature in a mode of laying a temperature measuring cable in advance in a bin before grain is put into the bin. Because the temperature measuring cable has higher manufacturing cost and large arrangement interval, the local heating of the grain pile can not be detected, and the manual cutting probe rod is used for measuring the temperature, but the manual cutting labor intensity is high, the local heating of the grains can not be found in the first time, and the local grains are moldy and deteriorated to cause large-area bad grains; the existing detection of the humidity of the grain pile is mainly carried out through a humidity sensor arranged above the grain surface in the bin, but the sensor can only detect the bin humidity, and the detection can not be carried out even if the local humidity of the grain pile is too high due to the condensation or the respiration and the transpiration of grains, and the local large-area bad grains of the grain pile can be caused.
The grain condition detecting rod (ZL 200910066192.5) disclosed in the Chinese patent literature is mainly characterized in that an insect collecting device is arranged between an insect attracting pipe and a cone head, and insect suction pipes connected with the insect collecting device are used for easily forming a negative pressure environment beneficial to suction when sucking insects entering the insect collecting device, so that the insects in grains can be quickly pulled out, but because an insect collecting space formed by grooves at the bottom of the insect collecting device is an open type non-independent closed space, air leakage is easy to occur from a blind hole of the cone head when the insects are sucked by a negative pressure source, the insects in the insect collecting space cannot be completely pulled out, and further the accuracy of insect quantity detection is affected.
