Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to an emergency grain releasing device of a grain dryer. Background Art

[0002] Grain dryer is a type of dryer, which is a general term for various grain drying equipment. The circulating grain dryer is a model recommended by the Ministry of Agriculture. It uses low temperature, large air volume, multi-channel, drying and slow recovery process for drying. Its working process is as follows: the grain is sent to the top of the dryer by the elevator. After being filled, the grain slowly falls down. After passing through the drying section, it is sent to the bottom of the elevator by the lower auger, and then transported upward by the elevator, and evenly scattered by the upper auger; the grain that has been dried once is slowed down in the storage section, and then flows to the drying section for drying again, and the cycle repeats until the moisture in the grain reaches the set value. However, when the dryer fails to operate, the grain in the machine body cannot be discharged at this time. The grain remaining in the machine body for a long time will cause the grain to be over-dried and reduce the quality of the grain; and once the machine fails, it is even necessary to disassemble the dryer before the grain can be cleaned out, which causes great trouble to users and maintenance personnel.

[0003] Application No.: CN201420645450.1 discloses an emergency grain release device for a dryer, including a dryer side plate, wherein the dryer side plate is provided with a grain release circular hole at the storage layer position, the grain release circular hole is connected to a grain release pipe with an inverted L-shaped structure, a long hole groove is provided on the upper part of the transverse part of the grain release pipe, and a removable first plug plate is inserted in the long hole groove. When the dryer fails to work due to a malfunction, grains accumulate in a large amount in the storage layer. At this time, the first plug plate is pulled up, and the grains will flow out of the machine body along the grain release pipe, thereby achieving the function of emergency grain release.

[0004] However, the above device needs to be manually operated when used, which is not timely and convenient. Therefore, it is necessary to propose an emergency grain release device for a grain dryer. Utility Model Content

When the sliding sleeve block moves, the sliding block slides in the sliding groove to prevent the sliding sleeve block from rotating when moving.
