referring to the drawings, and to fig. 1-7, an embodiment of a drying mechanism of a grain drying machine with a drying mechanism is generally indicated by 1, and in particular, referring to fig. 1, the drying mechanism 1 generally includes a drying rack with multiple air inlet channels 2 indicated by 11, a drying part 3 for grains to fall is disposed between two adjacent air inlet channels 2, two ends of each air inlet channel 2 are respectively connected to an air inlet and an air outlet, and hot air in the air inlet channels 2 flows from the air inlet channels 2 to the drying part 3 through a ventilation path between the air inlet channels 2 and the drying part 3, so as to complete a drying operation of the drying part 3.

Referring particularly to fig. 3 and 4, in fig. 3 and 4, the mesh 4 on the vent path is illustrated as being generally rectangular but with rounded corners. As an example, the length and width of the mesh 4 is adapted to the ventilation path and the mesh 4 blocks the ventilation path. However, it will be appreciated that the mesh 4 is adapted to the ventilation path arrangement, e.g. the ventilation path is circular, square or other suitable shape, in which case the mesh 4 is adapted.

In describing the ventilation member 5, for reference purposes, one end of the ventilation member 5 extends generally horizontally through the mesh sheet 4 and from the air supply path 2 to the drying part 3, and thus, the front surface of the ventilation member 5 faces the air supply path 2 and the rear surface faces the drying part 3.

In the illustrated embodiment, the mesh sheet 4 and the ventilation member 5 are detachably engaged, but in general, the mesh sheet and the ventilation member may be designed to be engaged, however, in this example, particularly referring to fig. 6, fig. 6 enlarges the specific structure of the thermal expansion positioning member 6 and the locking groove 411, the thermal expansion positioning member 6 is disposed on the outer circumferential surface of the diffuser section 54 and the inlet section 51, at least two ventilation holes 41 configured to engage with the ventilation member 5 are disposed on the mesh sheet 4, the locking groove 411 for locking the expanded thermal expansion positioning member 6 is disposed on the inner wall of the ventilation hole 41, so that the ventilation member 5 is locked on the ventilation hole 41 after the hot air flows; and when not letting in hot-blast, utilize the great characteristic of venturi structure both ends diameter, when the thermal expansion setting element 6 at its both ends did not lock and die in locking groove 411, this venturi structure and ventilation hole 41 are the joint state for above-mentioned ventilation 5 can be convenient from ventilation hole 41 dismouting, it is comparatively convenient to use. However, the locking groove 411 needs to be better locked after the thermal expansion positioning element 6 expands, and in this embodiment, the locking groove 411 is designed to be T-shaped to better complete the locking operation of the thermal expansion positioning element 6, and of course, the locking groove 411 may also be designed to be dovetail-shaped.

Referring particularly to fig. 6, the ventilation member 5 in fig. 6 includes an inlet section 51, a converging section 52, a throat 53 and a diverging section 54, wherein the inlet section 51, the converging section 52, the throat 53 and the diverging section 54 are arranged in sequence from the front to the back of the ventilation member 5.

In particular, the method comprises the following steps of,

the inlet section 51 is cylindrical;

the diameter of the above-mentioned closing-in section 52 tapers along the ventilation path 4;

the throat 53 has a cylindrical shape;

the diffuser section 54 increases in diameter along the vent path.

As an example, the aforementioned inducer 51 may suitably have a length of between 10-15 cm; the above-mentioned closing-in section 52 may suitably have a length of between 5 and 10 cm; the throat 53 may suitably have a length of between 15 and 20 cm; the diffuser section 54 may suitably have a length in the range of 10-15.

For example, the diameter of the wide mouth of the inlet section 51 is the largest, and the diameter of the throat 53 is the narrowest, so that the ventilating member 5 can be completely assembled and disassembled by passing the ventilating member 5 through the inlet section 51.

The structure changes the original ventilation opening into a Venturi tube structure, and the Venturi tube structure guides hot air from the air inlet channel 2 to the drying part 3, so that the ventilation opening has unidirectionality; moreover, the venturi tube has good structural stability and smooth pressure difference characteristic, so that airflow entering the drying part 3 is stable, and the damage to grains in the drying part 3 is low; the three components are not easy to block after long-term use and have long service life.

It is further understood that the cross-sectional dimensions of the venting member 5 are suitably the same as the cross-sectional dimensions of the vent holes 41 of the mesh 4 to which the venting member 5 is secured, however, it is understood that the cross-sectional dimensions of the venting member 5 may be different from the cross-sectional dimensions of the vent holes 41 and remain within the scope of this invention, it is also contemplated that the cross-sectional dimensions of the venting member 5 need not each have the same cross-sectional dimensions of the vent holes 41.

The throat 53 of the illustrated embodiment is suitably provided with filtering functions, for example, by adding a filter element 8 to the inner cavity of the throat 53, and suitably by designing the number of filter elements 8 as a plurality, however, it should be understood that the filter element 8 may be mounted on one or more parts of any of the structures of the ventilation element 5, for example, on one or more of the inlet section 51, the mouth-closing section 52 and the diffuser section 54. It should also be understood that, to enhance the filtering effect of the filter elements 8 described above, the apertures of the plurality of filter elements 8 may also be successively reduced along the ventilation path.

Considering that the throat 53 having the filter 8 needs to be cleaned or replaced periodically so as not to affect the filtering effect of the throat 53, for example, the throat 53 is designed to be screwed to both the diffuser 54 and the inlet 51, and of course, the throat may be designed to be inserted to both the diffuser 54 and the inlet 51.

However, it should be understood that the cleaning and replacement of the throat 53 mainly aims at the filter 8 in the throat 53, and therefore, the filter 8 can be designed to be a detachable structure, generally speaking, a plug-in type fit is mostly adopted, and the plug-in type structure often inconveniently designs a pull-out structure at the position of the throat 53 where the filter 8 is detached in order to meet the installation of the throat 53 and the vent 41, so that the detachment of the filter 8 is very inconvenient, and in view of the above problem, with particular reference to fig. 7, the thermal expansion filler 9 and the jack in fig. 6 are enlarged in fig. 7, the present invention designs the jack 531 convenient to plug in and pull out and the thermal expansion filler 9 matched with the jack 531 on the throat 53, on one hand, when hot air passes through, the thermal expansion filler 9 completely fills the jack 531, on the other hand, when the detachment is performed, the jack 531 and the thermal expansion filler 9 have a gap, and the thermal expansion filler 9 is mostly of a soft structure, so that a worker can pull out and replace the thermal expansion filler 9 and the filter 8 through the gap, which is highly practical.

The embodiment of fig. 2 described below may be omitted without departing from the scope of the invention.

Referring to fig. 2, the embodiment improves the adaptability of the drying part 3, by additionally installing thermal expansion extrusion pieces 7 on the inner walls of the two sides of the drying part 3, after hot air flows into the drying part 3, the falling path of the grains is extruded towards the center of the drying part 3 in a two-side extrusion manner, so that the drying part 3 of the drying mechanism 1 is more concentrated, and the ventilation piece 5 facing the center of the drying part 3 is matched, so as to further enhance the drying effect of the drying mechanism 1.

It should be understood that the present invention is not limited to the particular embodiments described herein, but is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
