Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a vacuum rake dryer with a crushing mechanism. Background Art

[0002] A vacuum dryer is a low-temperature device that heats materials in a vacuum. It is used for dehydrating and drying high-value-added, heat-sensitive agricultural and sideline products, health products, foods, medicinal herbs, fruits and vegetables, and chemical raw materials. The rake vacuum dryer is a continuous improvement of the vacuum dryer, with targeted and adaptable improvements resulting in multiple variants.

[0003] The patent document with application number CN217179060U discloses a vacuum rake dryer with a crushing mechanism, which includes a horizontally arranged cylinder, in which hollow blades for material stirring are provided, and pusher scrapers are provided at the ends of the hollow blades. A plurality of spaced crushing blades are installed at the bottom of the cylinder, and the crushing blades are respectively arranged between the pusher scrapers of two adjacent hollow blades. Drive motors for driving the corresponding crushing blades to rotate are respectively installed outside the cylinder.

[0004] The rake teeth of a vacuum rake dryer are easily worn after long-term friction with the inner wall of the machine, resulting in a gap between the rake teeth and the machine body. Due to the increase in the gap, the adhered material may be retained on the inner wall of the machine, resulting in the accumulation of material, which in turn affects the subsequent production efficiency and product quality. To address the above problems, we have launched a vacuum rake dryer with a crushing mechanism. Utility Model Content

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0024] The utility model discloses a vacuum rake dryer with a crushing mechanism, which is mainly used in drying scenarios.

[0025] Reference Figures 1 to 6A vacuum rake dryer with a crushing mechanism includes: a dryer body 1, a feed port 2 fixedly connected to the top of the dryer body 1, a crushing assembly provided inside the feed port 2, a discharge port 3 fixedly connected to the bottom of the dryer body 1, a mounting rod 8 rotatably connected to the inside of the dryer body 1, a sleeve 9 rotatably connected to the outside of the mounting rod 8, a connecting rod 10 equidistantly fixedly connected to the outside of the sleeve 9, a rake tooth 11 fixedly connected to the bottom of the connecting rod 10, and a cleaning assembly provided on the outside of the mounting rod 8;

[0027] One side of the scraper 21 is set to a pointed surface;

[0028] A placement plate 12 is fixedly connected to one side of the dryer body 1, a second motor 13 is provided on the top of the placement plate 12, a first bevel gear 14 is fixedly connected to the top of the output shaft of the second motor 13, a second bevel gear 15 is fixedly connected to the outside of the sleeve 9, a third bevel gear 16 is fixedly connected to the outside of the mounting rod 8, and the first bevel gear 14 is meshed with the second bevel gear 15 and the third bevel gear 16 respectively.

[0029] In the above technical solution, considering that the rake teeth of the vacuum rake dryer are easily worn after rubbing against the inner wall of the machine body for a long time, there will be a gap between the rake teeth and the machine body. Due to the increase of the gap, the adhered materials may be retained on the inner wall of the machine body, resulting in the accumulation of materials, thereby affecting the subsequent production efficiency and product quality. In order to solve this problem, the specific operation is as follows: by starting the second motor 13 to drive the first bevel gear 14 to rotate, and then using the first bevel gear 14 to engage with the second bevel gear 15 and the third bevel gear 16 respectively, thereby driving the sleeve 9 and the mounting rod 8 in the opposite direction, and then driving the connecting rod 10 and The rake teeth 11 rotate clockwise, and at the same time, the connecting plate 17, the slider 19, the slide bar 20 and the scraper 21 rotate counterclockwise. The scraper 21 is used to scrape the material on the inner wall of the dryer body 1. A motor is used to drive the rake teeth 11 and the scraper 21 to rotate at the same time.

A first motor 7 is provided on one side of the feed port 2, and one end of the output shaft of the first motor 7 is fixedly connected to one end of one of the rotating rods 4; when the material is put into the feed port 2, the first motor 7 is started to drive one of the rotating rods 4 to rotate, and then the spur gear 6 is used to make the two rotating rods 4 rotate at the same time, thereby driving the crushing leaves 5 to rotate, and crushing large pieces of material into smaller particles. This can improve the consistency and uniformity of the material and ensure that each part can be evenly heated during the drying process.

[0031] Reference Figures 1 to 6 In a preferred embodiment, the first motor 7 and the second motor 13 are both electrically connected to an external controller;

[0032] Working principle: When in use, when the material is put into the feed port 2, the first motor 7 is started to drive one of the rotating rods 4 to rotate, and then the spur gear 6 is used to make the two rotating rods 4 rotate at the same time, thereby driving the crushing blades 5 to rotate, and the large pieces of material are crushed into smaller particles. The material enters the dryer body 1, and the first bevel gear 14 is driven to rotate by starting the second motor 13. Then, the first bevel gear 14 is engaged with the second bevel gear 15 and the third bevel gear 16 respectively, thereby driving the sleeve 9 and the mounting rod 8 in the opposite direction, and then driving the connecting rod 10 and the rake teeth 11 to rotate clockwise.
