Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a fertilizer drying machine. Background Art

[0002] Chemical fertilizers, referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods contain one or more nutrients required for the growth of crops. Also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc., they are not edible. Chemical fertilizers have simple ingredients and high nutrient content; they have fast fertilizer effects and strong fertilizer effects; some fertilizers have acid-base reactions; they generally do not contain organic matter and have no effect on soil improvement and fertilization. There are many types of chemical fertilizers, and their properties and application methods vary greatly. During the production of chemical fertilizers, they need to be dried to prevent waste materials from sticking together during long-distance transportation, thereby ensuring the quality of the fertilizer and the effect of later use. Therefore, this type of fertilizer drying equipment plays a very important role in the production and transportation of chemical fertilizers.

[0003] To address this, Chinese patent number CN211782457U proposes a fertilizer dryer. During the heating process, the fertilizer can be turned over by a stirring structure, which makes the fertilizer dry faster and improves the efficiency of fertilizer drying. The stirring structure also drives the exhaust pipe to rotate, and the exhaust pipe evenly transports the hot air into the interior of the fertilizer, ensuring the uniformity of the fertilizer drying.

[0004] However, the above technology turns the waste material during the process of drying the fertilizer to speed up the drying speed, but after drying, the staff still needs to open the discharge end of the drying container for manual discharge. The fertilizer stuck to the inner wall of the container may not be dried thoroughly and needs to be manually scraped off and stored separately for secondary drying, which affects the overall production efficiency and increases the workload of the staff. In this regard, this design proposes a fertilizer dryer. Utility Model Content

A plurality of stirring shafts are fixedly provided at equal intervals on both sides of the outer wall of the roller shaft. A scraping blade is fixedly provided at the edge on one side of the sealed turntable, and one side of the scraping blade is in contact with the inner wall of the drying tank. An installation frame is fixedly provided at one end of the inner wall of the drying tank where the sealed turntable is located. A motor is installed on the inner wall of the installation frame, and the output end of the motor is fixedly connected to the other side of the sealed turntable. A heating plate is installed at the middle position on the top of the base. One side of the bottom of the drying tank is hinged to one side of the top of the base. A hydraulic rod is rotatably provided at the tail of the base.

[0008] In one example, arc-shaped connecting grooves are formed at both ends of the top of the base. A plurality of rollers are rotatably provided at equal intervals on the inner walls of the two arc-shaped connecting grooves. A connecting frame is fixedly provided at the middle position of one end of the drying tank.

[0009] In one example, the outer wall of one end of the hydraulic rod is rotatably connected to the inner wall of the connecting frame. Limit retaining rings are sleeved on both ends of the outer wall of the drying tank, and the outer walls of the plurality of rollers are respectively in rolling connection with the inner walls of the two limit retaining rings.

[0010] In one example, a feed funnel is inserted through one side of the top of the drying tank. A discharge chute is formed at the lower edge of the other end of the drying tank. A limit sliding groove is formed at the edge of the inner wall of the discharge chute.

[0011] In one example, a sealing plate is slidably provided on the inner wall of the limit sliding groove. A handle is fixedly provided on one side of the sealing plate. A guiding chute is fixedly provided at the lower edge of one end of the drying tank where the discharge chute is located.

[0026] Both ends of the top of the base 2 are provided with arc-shaped connecting grooves 309. The inner walls of the two arc-shaped connecting grooves 309 are rotatably provided with multiple rollers 310 at equal distances. A connecting frame 311 is fixedly provided in the middle position of one end of the drying can 1, and the hydraulic rod 308 is rotatably connected to the inner wall of the base 2 and one end of the connecting frame 311. When the drying can 1 is extended or retracted, it can lift up the drying can 1 and tilt it without any resistance. When the drying can 1 is dropped and placed horizontally, it is supported by one end of the base 2 and the multiple rollers 310 in the arc-shaped connecting grooves 309. The rolling properties of the rollers 310 act as a buffer when the drying can 1 falls, and it is not easy to cause significant wear.

[0027] Furthermore, the outer wall of one end of the hydraulic rod 308 is rotatably connected to the inner wall of the connecting frame 311. Both ends of the outer wall of the drying tank 1 are sleeved with a limit clamp 4, and the outer walls of the plurality of rollers 310 are respectively connected to the inner walls of the two limit clamps 4 in a rolling manner. The middle area of the limit clamp 4 is concave. When the drying tank 1 falls, the roller 310 is clamped into the concave part of the limit clamp 4, making its support more stable. When the internal part is stirred, the drying tank 1 is not easy to shake.

[0028] Furthermore, a feed funnel 5 is inserted on one side of the top of the drying tank 1, and a discharge trough 6 is provided at the lower edge of the other end of the drying tank 1.

Then, the sealing plate 8 is pulled through the handle to slide in the limit chute 7 to close the discharge chute 6. The heating plate 307 on the base 2 is started to heat the drying tank 1. At the same time, the motor 306 in the mounting frame 305 is started to drive the rotating sealing turntable 301, and then the roller shaft 302 is rotated to drive the stirring shaft 303 to rotate and stir the fertilizer, so that it is evenly heated and fully dried. While the sealing turntable 301 rotates, it will drive the scraping blade 304 to rotate closely against the inner wall of the drying tank 1, scrape off the fertilizer adhering to the inner wall for drying treatment. After drying, the hydraulic rod 308 is started to open the sealing plate 8, and the dried fertilizer is discharged from the discharge chute 6 through the inclination of the drying tank 1. The fertilizer adhering to the inner wall of the drying tank 1 falls and dries due to the scraping of the scraping blade 304 and is discharged together. It does not require manual discharging by the staff, and also reduces the probability of the need for secondary drying of the sticky fertilizer, reducing the work burden of the staff.
