Description

Technical field:

[0001] The utility model belongs to the technical field of grain dryers, in particular to an inclined slideway three-way component used for grain dryers. Background technology:

[0002] The existing Chinese utility model patent (authorization announcement number CN214892514U) discloses a sloping slide unloading mechanism for a grain dryer, which includes a sloping slide that is arranged obliquely and whose high end is higher than the low end. The high end of the sloping slide is used to communicate with the discharge end of the circulating conveying mechanism, and the low end is used to communicate with the grain bin of the dryer. The sloping slide is provided with a dust removal channel, the inner port of the dust removal channel is connected to the sloping slide, and the outer port is connected to the air inlet of the external wind source. The negative pressure generated by the external wind source drives the air flow in the sloping slide through the dust removal channel. In addition, the bottom surface of the high end of the sloping slide is provided with a grain discharge hopper whose feed port is connected to the sloping slide, and the discharge port of the grain discharge hopper is provided with a valve device. That is, by opening the valve device, the grains can be discharged from the sloping slide through the grain discharge hopper.

[0003] However, in actual applications, it is found that when the valve device set at the discharge port of the grain hopper is in a closed state, the grains will accumulate in the grain hopper. When the valve device is opened, the accumulated grains cannot fall from the grain hopper due to the mutual friction between the grains. It is often necessary to manually extend a rod into the grain hopper to interfere and destroy the force balance between the grains so that the grains can fall normally and clear the grain hopper. Summary of the invention:

[0004] The utility model aims to provide an inclined slide tee assembly for a grain dryer, which sets a flip valve at a bifurcation between two lower ends, and effectively interferes with the force balance between grains by means of the flipping movement of the flip valve, thereby avoiding grain accumulation and blocking the grain outlet.

[0005] The utility model is achieved in this way:

When the flip valve blocks one of the lower ends, the two limiting protrusions of the lower end respectively abut against the edges on both sides of the flip valve.

[0009] In the above-mentioned inclined slide tee assembly for a grain dryer, a sealing strip is arranged on the top side wall surface of the inner port of the two lower ends along the axial direction of the valve shaft, and when the flip valve blocks one of the lower ends, the sealing strip of the lower end abuts against the outer end edge of the flip valve.
