Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a grain drying device for agricultural machinery. Background Technology

[0002] In modern agricultural production, grain drying is a crucial step in ensuring grain quality and reducing post-harvest losses. With the continuous development of large-scale agricultural operations, the demand for grain drying equipment is increasing, and higher requirements are being placed on its drying efficiency, quality, and ease of operation. Grain drying equipment has emerged to address these challenges in traditional grain drying processes, such as uneven drying, high energy consumption, and difficult material feeding. Through an optimized drying system and convenient feeding mechanism, this equipment can achieve efficient, energy-saving, and stable grain drying operations, improve grain processing quality, reduce labor intensity and production costs, provide strong technical support for the modernization of agricultural production, and promote the sustainable development of the agricultural industry.

[0003] Traditional agricultural machinery grain drying equipment has a relatively simple mechanical structure and single function. In terms of drying, it usually adopts a relatively crude heating method, directly using the hot air generated by the hot air furnace to blow into the drying chamber through a simple air duct.

[0004] However, after the grain drying process is completed, traditional agricultural machinery grain drying equipment often requires manual assistance to clear blockages, such as using tools to knock on the drying chamber walls or manually cleaning the blockages in the discharge port. This not only consumes a lot of time and manpower, but also makes it difficult to ensure the continuity and uniformity of the discharge due to the instability of manual operation, which easily leads to grain spillage and waste. In addition, a slow discharge speed will also reduce the turnover efficiency of the entire drying equipment. Therefore, a grain drying device for agricultural machinery is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grain drying device for agricultural machinery, which aims to improve the problem in the prior art where, after the grain drying is completed, the feeding process requires manual assistance to clear the blockage, making it difficult to ensure the continuity and uniformity of the feeding, and easily causing grain spillage and waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A grain drying device for agricultural machinery includes a base, a fixed frame fixedly connected to the top of the base, a feeding hopper fixedly connected inside the fixed frame, a fixed frame fixedly connected to one side of the feeding hopper, a dryer fixedly connected to the top of the fixed frame, an air outlet pipe fixedly connected inside the dryer, a discharge hopper fixedly connected to the bottom of one side of the fixed frame, and a discharge assembly provided inside the fixed frame.

[0008] The feeding assembly includes a scraper, which is slidably connected inside the fixed frame. A groove is provided inside the fixed frame. A slide rod is fixedly connected to one side of the scraper and slidably connected inside the groove. A handle is fixedly connected to one end of the slide rod. A slide plate is slidably connected inside the fixed frame. A screen hole is provided inside the slide plate. The scraper fits against the slide plate. A connecting component is provided on one side of the slide plate.

[0009] As a further description of the above technical solution:

[0010] The connecting component includes a connecting block and a limiting block. One side of the connecting block is fixedly connected to one side of the sliding plate, and the bottom of the limiting block is fixedly connected to the top of the connecting block.

[0011] As a further description of the above technical solution:

[0012] A connecting frame is fixedly connected to one side of the fixed frame, and the limiting block is slidably connected inside the connecting frame;

[0013] As a further description of the above technical solution:

[0014] The connecting frame is fixedly connected with symmetrical support columns, and a locking block is slidably connected to the outer wall of one of the support columns.

[0015] As a further description of the above technical solution:

[0016] Another support column is slidably connected to a second locking block on its outer wall, and both the first locking block and the second locking block are in contact with the limiting block;

[0017] As a further description of the above technical solution:

[0018] A lever is fixedly connected to one side of the card block, and springs are sleeved on the outer walls of both support columns.

[0019] As a further description of the above technical solution:

[0020] One of the springs is fixedly connected at both ends to the first locking block and the inside of the connecting frame, respectively, and the other spring is fixedly connected at both ends to the second locking block and the inside of the connecting frame, respectively.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by pulling the handle, the slide bar slides in the chute, and the slide bar drives the scraper to move above the slide plate in the fixed frame. The scraper pushes the grain to the hopper, and the screen holes on the slide plate allow impurities to fall out, achieving a uniform and efficient feeding effect. This solves the problem that the feeding process requires manual assistance to clear the blockage, making it difficult to ensure the continuity and uniformity of the feeding, and easily causing grain spillage and waste, thereby improving production efficiency.

[0023] 2. In this utility model, the slide plate is slid into the fixed frame, and its limiting block presses against the first and second locking blocks in the connecting frame, causing the spring to contract. After the slide plate is in place, the spring rebounds and drives the locking blocks to fix the limiting block, thus achieving a quick and easy disassembly and assembly of the slide plate. This solves the problem of difficult, time-consuming and labor-intensive disassembly and assembly of the slide plate in traditional devices, thereby improving the flexibility of the drying device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 and Figure 2This utility model provides an embodiment of a grain drying device for agricultural machinery, including a base 1, a fixed frame 2 fixedly connected to the top of the base 1, a feeding hopper 3 fixedly connected inside the fixed frame 2, the feeding hopper 3 being located inside the fixed frame 2 for receiving and storing grain to be dried, a fixed frame 4 fixedly connected to one side of the feeding hopper 3 for providing a space to hold grain and perform drying, screening and feeding, a dryer 5 fixedly connected to the top of the fixed frame 4 for providing high-temperature airflow to the grain to achieve rapid and uniform drying, an air outlet pipe 6 fixedly connected inside the dryer 5 for discharging moisture and hot air generated during the drying process, a feeding hopper 7 fixedly connected to the bottom of one side of the fixed frame 4 for receiving grain after drying and cleaning impurities, and a feeding assembly provided inside the fixed frame 4;

[0031] The feeding assembly includes a scraper 21, which is slidably connected inside the fixed frame 4. The main function of the scraper 21 is to push the grain along the bottom of the fixed frame 4 and push it into the hopper 7. A groove 10 is provided inside the fixed frame 4. A slide rod 11 is fixedly connected to one side of the scraper 21. The slide rod 11 is connected to the scraper 21 and slides through the groove 10 inside the fixed frame 4. The slide rod 11 is slidably connected inside the groove 10. A handle 12 is fixedly connected to one end of the slide rod 11. The one end of the slide rod 11 is pulled by the handle 12, which drives the scraper 21 to slide along the slide plate 8, thereby pushing the grain out. A slide plate 8 is slidably connected inside the fixed frame 4. A sieve hole 9 is provided inside the slide plate 8. The scraper 21 fits against the slide plate 8. A connecting assembly is provided on one side of the slide plate 8.

[0032] Specifically, when using this grain drying device, the grain first needs to be placed into the feed hopper 3. Through the feed hopper 3, the grain is fed into the fixed frame 4. At this time, the dryer 5 can be started. The dryer 5 uses heat to efficiently dry the grain inside the fixed frame 4. After drying, the user can start the sliding operation by pulling the handle 12. The handle 12 is connected to the slide rod 11. The slide rod 11 can slide smoothly inside the slide groove 10. The slide rod 11 generates power through the traction of the handle 12 and moves smoothly within the slide groove 10. The other end of slide bar 11 is connected to a scraper 21. Driven by slide bar 11, scraper 21 slides along the slide plate 8 inside the fixed frame 4, thus pushing the grain. The slide plate 8 has multiple sieve holes 9 inside, which are used to effectively remove impurities mixed in with the grain from the fixed frame 4 when the scraper 21 pushes the grain, ensuring that the grain entering the hopper 7 is pure and free of impurities. The feeding process is achieved by pushing the grain with scraper 21, which pushes the grain smoothly into the hopper 7. The hopper 7 is usually equipped with an inclined design or auxiliary device to help the grain flow to the outlet under gravity, thus completing the feeding process, improving the working efficiency of the equipment, making the grain feeding process more convenient, avoiding manual intervention, and reducing labor intensity.

[0033] Reference Figures 1-3 The connecting assembly includes a connecting block 13 and a limiting block 14. One side of the connecting block 13 is fixedly connected to one side of the slide plate 8, and the bottom of the limiting block 14 is fixedly connected to the top of the connecting block 13. One side of the fixing frame 4 is fixedly connected to a connecting frame 15. The limiting block 14 is slidably connected inside the connecting frame 15, which restricts the range of motion of the slide plate 8 and the connecting block 13. Symmetrical support columns 16 are fixedly connected inside the connecting frame 15. One of the support columns 16 has a locking block 17 slidably connected to its outer wall, and the other support column 16 has a locking block 17 slidably connected to its outer wall. The sliding connection includes a second locking block 20. Both the first locking block 17 and the second locking block 20 are in contact with the limiting block 14. A lever 18 is fixedly connected to one side of the first locking block 17. Springs 19 are sleeved on the outer walls of the two support columns 16. The function of the springs 19 is to provide appropriate restoring force to ensure the stability of the first locking block 17 and the second locking block 20 when sliding. One spring 19 is fixedly connected at both ends to the first locking block 17 and the connecting frame 15, respectively. The other spring 19 is fixedly connected at both ends to the second locking block 20 and the connecting frame 15, respectively.

[0034] Specifically, when the skateboard 8 needs to be disassembled and maintained, the user first needs to slide the skateboard 8 into the fixed frame 4. The skateboard 8 is equipped with a limit block 14 on one side. The function of the limit block 14 is to guide the skateboard 8 to the correct position. The limit block 14 can cooperate with the connecting frame 15 in the fixed frame 4 to ensure that the skateboard 8 can slide in smoothly. At this time, the limit block 14 will cause the first locking block 17 and the second locking block 20 to move. Locking blocks 17 and 20 are fixed by spring 19, and the stability of the locking blocks is maintained by the elasticity of spring 19. The function of locking blocks 17 and 20 is to prevent the slide plate 8 from accidentally falling off or moving during operation by locking and fixing it. As the slide plate 8 slides into the fixed frame 4, locking blocks 17 and 20 will be squeezed and moved to both sides, thereby releasing the original locking state. As the locking blocks are displaced, spring 19 will be squeezed and contracted, reducing the restoring force of spring 19 until the slide plate 8 is completely inside the fixed frame 4. At this time, spring 19 will rebound under the action of restoring force, pushing locking blocks 17 and 20 to reset and re-lock into the side of the limit block 14, thereby completing the stable fixing of the slide plate 8. This ensures that the slide plate 8 can be quickly disassembled during maintenance, reducing downtime and improving the maintenance efficiency of the equipment.

[0035] Working Principle: When using this grain drying device, first, put the grain into the feed hopper 3, which then feeds the grain into the fixed frame 4. At this time, start the dryer 5 to dry the grain inside the fixed frame 4. After drying, pull the handle 12 to make it slide the slide rod 11 inside the slide groove 10. The slide rod 11, under force, drives the scraper 21 at one end to slide above the slide plate 8 inside the fixed frame 4. This causes the scraper 21 to push the grain above the slide plate 8. At the same time, through the sieve holes 9 inside the slide plate 8, impurities mixed in between fall out of the fixed frame 4 during the pushing process. Finally, the scraper 21 pushes the grain into the discharge hopper 7 to complete the discharge, thus achieving convenient drying. For the purpose of feeding grains, when the slide plate 8 needs to be disassembled and maintained, the slide plate 8 is first slid into the fixed frame 4. During this process, the limiting block 14 on one side of the slide plate 8 will slide into the connecting frame 15 on one side of the fixed frame 4, and squeeze the first locking block 17 and the second locking block 20, causing the first locking block 17 and the second locking block 20 to move to both sides. At the same time, the first locking block 17 and the second locking block 20 squeeze the spring 19 connected to them, causing it to contract. When the slide plate 8 is completely slid into the fixed frame 4, it will rebound by the spring 19, thereby driving the first locking block 17 and the second locking block 20 to reset, so that they are locked on the side of the limiting block 14 and fixed, thus achieving the effect of easy disassembly and maintenance of the slide plate 8.
