[0033] Example 3

[0034] Please refer to 1-2. The present invention provides a detailed description and technical supplement of the connecting mechanism based on Example 1-2. The connecting mechanism includes a first connecting ring body 22 and a second connecting ring body 23 arranged in the vertical bin body 1. The opposite surfaces of the first connecting ring body 22 and the second connecting ring body 23 are in close contact and maintain relative rotation. The first connecting ring body 22 is fixedly mounted on the lower surface of the mounting plate 12, and the second connecting ring body 23 is fixedly mounted on the top of each group of scraper plates 9.

When the driving motor 2 drives the rotating shaft and the scraper plate 9 to rotate and then drives the spiral blade 7 and the scraper plate 9 to rotate, the air introduced by the air inlet pipe 24 enters the annular passage formed by the first annular groove and the second annular groove, and then is sprayed into the vertical bin body 1 through the air delivery pipe 11 from the air jets 10 set on each group of scraper plates 9, so as to ventilate and blow the partition in the vertical bin body 1 to ensure that the fertilizer is in a dry state and thus avoid agglomeration; at the same time, when the second communicating ring body 23 is driven to rotate by the scraper plate 9, the first annular groove and the second annular groove are always in a closed and connected state, which can ensure the stable transportation of external air.

[0035] Example 4

[0036] See also Figure 1-3, and further supplementary explanation is given to the present application in combination with Example 1. A feed through hole is provided on the mounting plate 12 to ensure that fertilizer is input into the vertical bin body 1, and a sealing cover 25 is installed on the feed through hole. An exhaust pipe 26 connecting the inside of the vertical bin body 1 with the external space is vertically plugged on the sealing cover 25, and a one-way valve for controlling the flow of air from the inside of the vertical bin body 1 to the external space is installed inside the exhaust pipe 26, so that the excess air blown from the vertical bin body 1 through the air jet 10 is conveniently discharged to the outside, so as to ensure that the pressure state in the vertical bin body 1 is at a normal level;

[0037] The periphery of the silo body 1 is covered with a heat-insulating material, and the heat-insulating material is made of asbestos material to prevent the internal temperature of the silo body 1 from being higher than the normal level due to sunlight, thereby ensuring the stability of the fertilizer stored therein;

[0038] A single chip microcomputer is also provided, and an air pump is installed on the air inlet pipe 24. A humidity sensor is provided on the inner side of the vertical bin body 1, and the control module of the drive motor 2, the control module of the air pump, and the humidity sensor are all connected with the single chip microcomputer signal data. The humidity environment inside the vertical bin body 1 is detected by the humidity sensor provided in the vertical bin body 1, and the detected humidity data is transmitted to the single chip microcomputer. The single chip microcomputer analyzes and processes the received humidity data. When the humidity data is higher than the set value, the single chip microcomputer controls the drive motor 2 to work, so as to drive the turning mechanism and the scraping mechanism to work stably, so as to turn and stir the fertilizer stored in the vertical bin body 1 to avoid the fertilizer from agglomerating. At the same time, the single chip microcomputer controls the air pump to work, and the outside air is passed into the vertical bin body 1 through the air jet 10, so as to separate the moisture carried in the fertilizer and discharge it through the exhaust pipe 26.

[0039] The feed port 4 and the discharge port 5 each include multiple groups, and are evenly distributed in a circular array around the feed pipe body 3, to ensure that the fertilizer at the bottom of the vertical bin body 1 can be stably introduced into the feed pipe body 3 through each group of feed ports 4, and to ensure that the fertilizer lifted to the top of the feed pipe body 3 by the cooperation of the power shaft 6 and the spiral blades 7 can be output through each group of discharge ports 5, thereby realizing the turning over of the fertilizer.

[0040] Example 5

[0041] See also Figure 1 , 3, the discharge valve structure in the present application is described in detail, the bottom end of the vertical bin body 1 is equipped with a discharge valve structure, the discharge valve structure includes: a mounting tube 27 fixedly mounted on the outside of the bottom end of the vertical bin body 1, a baffle plate 28 nested in the mounting tube 27 in a relatively rotatable manner and tightly attached to the outer wall of the vertical bin body 1, and a mounting shaft 29 fixed at the center of the baffle plate 28; a third direction-changing gear 30 is fixed on the mounting shaft 29, and the third direction-changing gear 30 is meshedly connected with a fourth direction-changing gear 31, and the fourth direction-changing gear 31 is fixedly connected with a driving wheel 32 arranged on the outside of the mounting tube 27 through a connecting rod; the baffle plate 28 and the baffle plate 28 are provided on the vertical bin body 1, and the discharge through hole 33 is offset from the center position of the mounting tube body 27; when the discharge valve structure is controlled to be in an open or closed state to control the discharge state of the fertilizer in the vertical bin body 1, the fourth direction-changing gear 31 fixedly connected to the driving wheel 32 is driven to rotate, thereby driving the third direction-changing gear 30 and the mounting shaft 29 and the baffle plate 28 fixed to the third direction-changing gear 30 to rotate. When the discharge through hole 33 located on the vertical bin body 1 is opposite to the discharge through hole 33 located on the baffle plate 28, the fertilizer in the vertical bin body 1 can be discharged outward.

[0042] Example 6

[0043] See also Figure 1-3 , and in combination with Examples 1-5, the workflow, working principle and beneficial effects of the present invention are described in detail:

[0044] By opening the sealing cover 25, high-humidity and easy-to-cake fertilizer is input into the vertical bin body 1, and the fertilizer entering the vertical bin body 1 freely settles to the bottom of the vertical bin body 1 under its own gravity, and the driving motor 2 is controlled to work to drive the power shaft 6 and the spiral blade 7 to rotate, so that the fertilizer at the bottom of the vertical bin body 1 is lifted to the top of the conveying pipe body 3 and discharged through the discharge port 5, and the fertilizer discharged from the discharge port 5 is allowed to fall freely, so as to realize continuous turning of the fertilizer in the vertical bin body 1, which can effectively prevent its caking;

[0045] External dry air is discharged into the vertical bin body 1 through the air inlet pipe 24, the first annular groove, the second annular groove, the air delivery pipe 11, and the air jet 10, so as to increase the dry air to fully contact with the fertilizer being turned, and then discharge the moisture in the fertilizer through the exhaust pipe 26. Since the air jet 10 is evenly distributed on each group of scraper plates 9, the dry air can be fully contacted with the high-humidity fertilizer to ensure that the high-humidity fertilizer is quickly dried;

[0046] During the operation of the driving motor 2, each group of scraper plates 9 is driven to rotate stably, thereby scraping off the high-humidity fertilizer attached to the inner wall of the vertical bin body 1 to prevent it from clumping on the inner wall of the vertical bin body 1. At the same time, the continuous rotation of each group of scraper plates 9 can act as a stirring blade to fully stir the fertilizer in the vertical bin body 1 to prevent it from clumping.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
