[0022] Compared with related technologies, the grain discharge device of the grain dryer proposed in this utility model has the following beneficial effects:

[0023] In this utility model, the grain discharge device of a grain dryer, through the set grain discharge mechanism, when the grain is discharged from the grain dryer and conveyed on the conveyor belt, the electric telescopic rod can drive the crossbeam and the movable grain discharge plate set on the lower side of the crossbeam to move up and down synchronously, so as to change the distance between the bottom of the movable grain discharge plate and the conveyor belt, thereby achieving a uniform grain discharge effect and the thickness of the discharged grain is controllable and adjustable, which has strong applicability. In addition, the mounting cylinders are evenly distributed and spaced on the movable grain discharge plate. Under the action of the spring on the inner side of the mounting cylinder, the bottom of the sliding rod will be driven to abut against the conveyor belt. As the grain is conveyed on the conveyor belt, it will be divided into several strips by the sliding rod, thereby increasing the contact area between the grain and the air on the inner bottom, thus enhancing the heat dissipation effect of the grain, preventing the grain from accumulating heat inside and deteriorating, and enhancing the practicality of this utility model.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-5A grain discharge device for a grain dryer includes a grain dryer 1, a support 4 on the side of the grain dryer 1, a conveyor belt 5 installed inside the support 4, and a grain discharge mechanism 6 and a cooling mechanism 7 installed on the upper side of the support 4. The grain discharge mechanism 6 includes a first mounting base 61, an electric telescopic rod 62 fixedly installed on the upper side of the first mounting base 61, a crossbeam 63 fixedly installed on the upper side of the electric telescopic rod 62, a movable grain discharge plate 65 at the bottom of the crossbeam 63, a plurality of mounting cylinders 67 fixedly installed at the bottom of the movable grain discharge plate 65, a sliding rod 68 slidably installed inside the mounting cylinder 67, a spring 610 fixedly connected between the upper end of the sliding rod 68 and the inner side of the mounting cylinder 67, a ball bearing 69 rollingly installed at the bottom of the sliding rod 68, the spring 610 being a compressed spring, and the mounting cylinders 67 being evenly distributed along the movable grain discharge plate 65.

[0032] With the above structure, under the rebound force of the spring 610, the ball bearing 69 at the bottom of the slide rod 68 always remains in contact with the upper side of the conveyor belt 5. When the conveyor belt 5 moves, the ball bearing 69 reduces the friction between the bottom of the slide rod 68 and the conveyor belt 5 through its own rotation.

[0033] In this embodiment, the cooling mechanism 7 includes a gantry 72, a horizontal pipe 75 is provided on the upper side of the gantry 72, and a plurality of folded pipes 76 are connected to the bottom of the horizontal pipe 75. The folded pipes 76 pass through to the bottom of the gantry 72. An air pump 77 is provided on the side of the support 4, and a connecting pipe 78 is connected between the air pump 77 and the horizontal pipe 75.

[0034] With the above structure, by activating the air pump 77, air can be blown from the connecting pipe 78 and the horizontal pipe 75 into the conveyor belt bend 76, and then blown laterally onto the conveyor belt 5 from the bend 76, increasing the air flow rate on the upper side of the conveyor belt 5, thereby enhancing the cooling and heat dissipation effect on the grain conveyed on the conveyor belt 5. It should be noted that by controlling the output power of the air pump 77 to make the air flow rate blown out of the bend 76 appropriate, the grain conveyed on the conveyor belt 5 will not be blown away.

[0035] In this embodiment, a vertical rod 64 is fixedly connected between the movable grain discharge plate 65 and the bottom of the crossbeam 63, and an arc surface 66 is provided at the bottom of the movable grain discharge plate 65.

[0036] Through the above structure, the vertical rod 64 provides a connecting support for the movable grain discharge plate 65 at the bottom of the crossbeam 63.

[0037] In this embodiment, a second mounting base 71 is fixedly connected to the bottom of the gantry 72. Both the second mounting base 71 and the first mounting base 61 are screwed onto the upper side of the bracket 4. A tube seat 74 is fixedly installed on the upper side of the gantry 72, and the tube seat 74 supports the bottom of the horizontal tube 75.

[0038] With the above structure, both the second mounting base 71 and the first mounting base 61 are screwed onto the upper side of the bracket 4, so that the grain discharge mechanism 6 and the cooling mechanism 7 can be disassembled from the bracket 4 for easy maintenance later.

[0039] In this embodiment, ventilation slots 73 are provided on both sides of the gantry 72, and the folded pipe 76 bends toward the ventilation slots 73.

[0040] With the above structure, the folded tube 76 bends to the side, thereby causing the air on the upper side of the conveyor belt 5 to flow to both sides, which facilitates the removal of heat from the grain being transported on the upper side of the conveyor belt 5.

[0041] In this embodiment, a control host 2 is fixedly installed on the side wall of the grain dryer 1, and a discharge port 3 is installed on the side of the grain dryer 1, which is located on the upper side of the conveyor belt 5.

[0042] With the above structure, the grain dried by the grain dryer 1 can be directly fed onto the conveyor belt 5 through the discharge port 3 for discharge and conveying.

[0043] In this invention, during use, the grain dryer 1 lowers the dried grain from the discharge port 3 onto the conveyor belt 5 for transport. The conveyor belt 5 transports the grain from the upper side to the right. When the grain passes the bottom of the movable grain discharge plate 65, the spacing between the movable grain discharge plate 65 and the upper side of the conveyor belt 5 restricts the grain thickness, achieving uniform material distribution. Simultaneously, the sliding rods 68 inside the mounting cylinders 67 evenly distributed on the movable grain discharge plate 65 divide the grain into several strips, increasing the contact area between the bottom inner grain and the air. Subsequently, as the grain passes the bottom of the gantry 72, air is pumped through the connecting pipe 78 and the horizontal pipe 75 through the conveyor belt bend 76, and blown laterally onto the conveyor belt 5, increasing the airflow rate on the upper side of the conveyor belt 5. This carries the heat from the grain to both sides of the conveyor belt 5, achieving a cooling effect on the grain and preventing internal heat accumulation that could lead to spoilage.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
