[0002] At present, during the drying process of "batch-type circulating grain dryers" on the market, the grain circulation is that the grains flow reversely into the elevator of the dryer, and then the buckets of the elevator scrape the grains from the rear to the front of the elevator horizontally. At the turning point, the grains are forced to be dug into the buckets, and then lifted by the elevator and sent into the tempering layer of the dryer. During this process, since the buckets of the elevator need to scrape the grains from the rear to the front horizontally, some grains will be scraped and broken, resulting in great drying losses. Therefore, it is of practical economic benefit to develop a structure to solve the grain lifting and drying losses. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Embodiment 1
[0025] As Figures 1 - 3 shown, the present invention provides a technical solution: a batch cycle grain dryer grain cycle positive lifting structure, including an equipment storage layer 1. A plurality of support frames 2 are fixedly connected to the bottom of the equipment storage layer 1. The bottom of the equipment storage layer 1 is connected and communicated with a lower conical inclined hopper 3. A valve is provided at the discharge port of the lower conical inclined hopper 3. The bottom of the lower conical inclined hopper 3 is connected and communicated with a cycle positive lifting flow pipe 4. The bottom of the cycle positive lifting flow pipe 4 is designed with a downward inclination angle. A hoist 5 is fixedly installed on the front of the equipment storage layer 1. A feed hopper 6 is fixedly connected to the front of the hoist 5. The feed hopper 6 is communicated with the internal lifting and feeding mechanism of the hoist 5. A feeding component 7 is fixedly installed at the bottom of the cycle positive lifting flow pipe 4. The position of the feeding component 7 matches the position of the feed hopper 6.
[0026] The feeding component 7 includes a feeding hopper 701. Connecting frames 702 are fixedly installed on both sides of the feeding hopper 701. The connecting frames 702 are in an inverted concave shape. The tops of the two connecting frames 702 are respectively fixedly connected to both sides of the cycle positive lifting flow pipe 4. A plurality of discharge pipes 703 are provided on one side of the feeding hopper 701 close to the feed hopper 6. The outlet ends of the plurality of discharge pipes 703 are all located above the feed hopper 6. So that during operation, grains are fed into the feed hopper 6 of the hoist 5, and then are positively lifted to the equipment storage layer 1 of the dryer by the internal lifting and feeding mechanism of the hoist 5. Then, they fall from the equipment storage layer 1 into the lower conical inclined hopper 3. The lower conical inclined hopper 3 can convey the grains into the cycle positive lifting flow pipe 4. Then, the cycle positive lifting flow pipe 4 conveys the grains into the feeding hopper 701. After the grains fall into the feeding hopper 701, they can slide and roll to the plurality of discharge pipes 703, and then can be discharged through the plurality of discharge pipes 703 into the feed hopper 6. During this process, since the grain cycle enters the feed hopper 6 of the hoist 5 through the above structure, there is no need to level and scrape the grains. Therefore, it can effectively avoid scraping and breaking some grains, and then effectively reduce the problem of drying loss.
[0027] The feeding hopper 701 is inclined downward, and the outlet ends of the discharge pipes 703 are inclined toward the inside of the feed hopper 6, so that it is convenient for the grains falling into the feeding hopper 701 to roll and slide to the discharge pipes 703, and the grains in the discharge pipes 703 can also better roll and slide until they slide down.
[0028] The connecting frame 702 is made of aluminum alloy material, and the connecting frame 702 is fixedly connected to both the feeding hopper 701 and the circulating positive lifting flow pipe 4 by welding, so that the connecting frame 702 has high self-rigidity and is not easily deformed or damaged, and the welding connection strength is high, and it is not easy to break and separate, which affects the normal operation and use of the equipment.
[0029] The inner wall and the inner bottom surface of the feeding hopper 701 are both smooth surfaces, and the inner pipe wall of the discharge pipe 703 is also a smooth surface, and the inner bottom surface of the feeding hopper 701 is inclined towards a plurality of discharge pipes 703, so that the friction between the grain and the feeding hopper 701 and the discharge pipe 703 can be reduced, which is convenient for the grain to slide and roll.
[0030] Embodiment 2
[0031] As Figures 3 - 5 shown, the difference between this embodiment and Embodiment 1 is that a dust collection assembly 8 is fixedly installed on the upper inclined surface of the circulating positive lifting flow pipe 4. The dust collection assembly 8 includes a dust collection box 801 and a suction fan 802. The dust collection box 801 is fixedly installed on the upper inclined surface of the circulating positive lifting flow pipe 4. A box door 803 is hinged on one side of the dust collection box 801. An intercepting filter plate 804 is movably clamped inside the dust collection box 801. The suction fan 802 is also fixedly installed on the upper inclined surface of the circulating positive lifting flow pipe 4, and the suction end of the suction fan 802 is connected to the inside of the dust collection box 801 in a communicating manner. A dust collection pipe 805 is connected to the side of the dust collection box 801 away from the suction fan 802 in a communicating manner. One end of the dust collection pipe 805 away from the dust collection box 801 is fixedly connected to a dust collection hood 806. The opening of the dust collection hood 806 is located above the feeding hopper 701, so that during the process of circulating and lifting the grain, when the grain falls from the circulating positive lifting flow pipe 4 into the feeding hopper 701, a large amount of dust will be generated. At this time, through the operation of the suction fan 802, in cooperation with the dust collection box 801, the dust collection pipe 805 and the dust collection hood 806, a large amount of generated dust can be pumped into the dust collection box 801, and the intercepting filter plate 804 inside the dust collection box 801 intercepts and filters the dust, and the dust is concentrated and intercepted in the dust collection box 801, and the clean air is discharged through the suction fan 802, so that a large amount of dust can be effectively prevented from drifting into the nearby air and endangering the nearby workers, reducing potential safety hazards, and subsequently, the inside of the intercepting filter plate 804 and the dust collection box 801 can be cleaned by opening the box door 803 and pulling out the intercepting filter plate 804 inside the dust collection box 801.
[0032] When the cabinet door 803 is closed, it is hermetically connected to the dust collection box 801. The dust collection hood 806 is in the shape of a horn with a wider bottom and a narrower top, which can ensure the sealing performance when the cabinet door 803 is connected to the dust collection box 801. The dust collection hood 806 in the shape of a horn with a wider bottom and a narrower top has a larger suction and delivery range, so that it is possible to better suction and deliver grain dust.
[0033] Working principle: During operation, the grain is fed into the hopper 6 of the elevator 5, and then is positively lifted to the equipment storage layer 1 of the dryer by the internal lifting and feeding mechanism of the elevator 5. Then it falls from the equipment storage layer 1 into the lower conical inclined hopper 3. The lower conical inclined hopper 3 can convey the grain into the circulating positive lifting flow pipe 4, and then the circulating positive lifting flow pipe 4 conveys the grain into the feeding hopper 701. After the grain falls into the feeding hopper 701, it can slide and roll to multiple discharge pipes 703, and then the grain can be discharged through the multiple discharge pipes 703 into the hopper 6. During this process, since the grain circulation enters the hopper 6 of the elevator 5 through the above structure and there is no need to level or scrape the grain, it is effectively avoided to scrape and break some grains, thus effectively reducing the problem of drying loss. During the process of circulating and lifting the grain, when the grain falls from the circulating positive lifting flow pipe 4 into the feeding hopper 701, a large amount of dust will be generated. At this time, through the operation of the exhaust fan 802, in cooperation with the dust collection box 801, the dust collection pipe 805 and the dust collection hood 806, the generated large amount of dust is sucked into the dust collection box 801. The intercepted filter plate 804 inside the dust collection box 801 intercepts and filters the dust, and the dust is concentrated and intercepted in the dust collection box 801, while the clean air is discharged through the exhaust fan 802, so that it is effectively avoided that a large amount of dust drifts into the nearby air and endangers the nearby workers, reducing the safety hazard. And subsequently, the intercepted filter plate 804 inside the dust collection box 801 can be pulled out by opening the cabinet door 803 to clean the intercepted filter plate 804 and the inside of the dust collection box 801.
