Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a fertilizer conveying and mixing device. Background Art

[0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility levels. Fertilizers can be divided into many types according to their source, composition, properties and fertilizer efficiency. According to their source, they can be divided into farmyard manure and chemical fertilizers. According to the types of nutrients they contain, they can be divided into simple fertilizers and compound fertilizers. According to their properties, they can be divided into solid fertilizers, liquid fertilizers, gas fertilizers, photosensitive fertilizers, etc. By mixing different types of fertilizers, the supply of different nutrients can be balanced to avoid excess or deficiency of certain nutrients, thereby improving the overall utilization rate of fertilizers.

[0003] After searching, the fertilizer conveying and mixing device disclosed in the Chinese patent with application number CN201922447492.X requires the use of an additional electric motor to achieve intermittent feeding, which increases the power consumption and is not energy-efficient. Therefore, the device has a simple structure and is easy to operate. The rotating shaft drives the unloading control plate to rotate to achieve intermittent feeding, and also drives the stirring rod to stir and mix the fertilizer, killing two birds with one stone and being more energy-efficient.

[0004] During the mixing process of the above-mentioned fertilizers, a stirring rod is usually used to mix the fertilizers, and the connection between the stirring rod and the motor is usually a fixed connection. When the stirring rod stirs the fertilizer, it is easy for the fertilizers of different properties to collide with each other. After a long period of stirring, the stirring rod will cause wear and corrosion by the fertilizer for a long time. It is not convenient to flexibly disassemble, maintain or replace the stirring rod, which can easily cause the stirring rod to be damaged during the stirring process, reducing the service life of the stirring rod, thereby increasing production costs and reducing work efficiency.

The stirring rod 7 is inserted into the inside of the mounting sleeve 6 and is fixed in the inside of the hole groove 8 by the clamping rod 11, which is conducive to simplifying the installation steps of the stirring rod 7, and the cooperation of the threaded groove 12 and the nut 13 is conducive to reinforcing the installed stirring rod 7.

[0033] As attached Figure 3 As shown, a motor 2 15 is fixedly installed in the middle of the bottom end of the mixing barrel 1, and a bottom rod 16 is fixedly connected to the output end of the motor 2 15, and a side scraper rod 17 is fixedly connected to one end of the bottom rod 16. The bottom rod 16 is convenient for scraping the bottom of the mixing barrel 1, and the side scraper rod 17 is convenient for scraping the side wall of the mixing barrel 1, and the cross-section of the side scraper rod 17 is set to be triangular.

[0034] As attached Figure 7As shown, the other end of the bottom rod 16 is fixedly connected to a mounting rod 18, and a plurality of mounting grooves 19 are arranged inside the mounting rod 18. A second spring 20 is fixedly connected to the right end of the mounting groove 19, and a cleaning brush 21 is fixedly connected to the other end of the plurality of second springs 20. A protective shell 22 is slidably connected to the inside of the mounting groove 19, and the left ends of the plurality of protective shells 22 are fixedly connected to the right end of the cleaning brush 21.

A plurality of cross nozzles are arranged at the bottom of the annular water spray head 26, which is beneficial for spraying water on the inner wall of the mixing barrel 1, thereby facilitating the cleaning of the side scraper 17 and the cleaning brush 21.

[0037] Working principle: when mixing fertilizers, start the motor 5, the output end of the motor 5 drives the mounting sleeve 6, thereby driving the stirring rod 7 to rotate, so that the stirring rod 7 can stir and mix the fertilizers. When the stirring rod 7 needs to be disassembled and replaced, the knob at the bottom of the screw rod 2 is turned, so that the screw rod 2 is driven to rotate when the knob is turned, so that the screw rod 2 can drive the connection frame 3 to rise in the process of rotation. When the connection frame 3 rises, it is conducive to driving the top cover 4 to rise, so that the top cover 4 can drive the motor 5, the mounting sleeve 6 and the stirring rod 7 to rise. When it rises to a certain height, the top cover 4 can drive the motor 5, the mounting sleeve 6 and the stirring rod 7 to rise. When the height is determined, the top of the stirring rod 7 will be exposed outside the mixing barrel 1, and then the nut 13 outside the threaded groove 12 is screwed, and the nut 13 is screwed out, so as to release the limit of the clamping rod 11, and then the pull rod 10 is pulled, so that when the pull rod 10 is pulled, the clamping rod 11 is pulled, thereby squeezing the first spring 14, which is conducive to driving the clamping rod 11 to break away from the inside of the hole groove 8 and move to the inside of the fixed shell 9, and then the stirring rod 7 is released from the limit, and then the stirring rod 7 is separated from the installation sleeve 6, so as to facilitate the removal of the stirring rod 7. The operation is reversed during installation. The stirring rod 7 is convenient for maintenance and replacement, thereby reducing maintenance costs. When the inner wall of the mixing barrel 1 needs to be cleaned, the motor 2 15 is turned on, and the output end of the motor 2 15 drives the bottom rod 16 to rotate. When the bottom rod 16 rotates, it is convenient to clean the bottom of the inner wall of the mixing barrel 1. When the bottom rod 16 rotates, it drives the side scraping rod 17 to rotate, thereby facilitating the scraping and cleaning of the inner wall of the mixing barrel 1. When the bottom rod 16 rotates, it drives the mounting rod 18 to rotate. During the rotation of the mounting rod 18, it is convenient to drive the cleaning brush 21 to rotate, and the second spring 20 When the cleaning brush 21 is pushed, the cleaning brush 21 is more closely attached to the inner wall, so that it is convenient to brush the inner wall of the mixing barrel 1, thereby improving the cleaning quality. When it is necessary to spray water to clean the inner wall of the mixing barrel 1, clean water is injected into the water tank 23, and then the water pump 24 is turned on. The pressure generated by the water pump 24 on the clean water is transmitted to the inside of the annular water spray head 26 through the water pipe 25, and then sprayed out according to the nozzles distributed at the bottom of the annular water spray head 26, which is convenient for spraying the inner wall of the mixing barrel 1, and then cooperates with the cleaning effect of the side scraper rod 17 and the cleaning brush 21, which is conducive to improving the cleaning quality.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
