Description

Technical Field

[0001] This invention belongs to the field of fertilizer production technology, and specifically relates to a granular sampler for fertilizer production. Background Technology

[0002] Chemical fertilizers refer to fertilizers made using chemical methods that contain one or more nutrients needed for crop growth. Chemical fertilizers containing only one nutrient element whose content can be labeled are called single-element fertilizers, such as nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, as well as minor macronutrient fertilizers and micronutrient fertilizers. Chemical fertilizers containing two or three of the three nutrients, namely nitrogen, phosphorus, and potassium, and whose content can be labeled, are called compound fertilizers or mixed fertilizers. The solubility of the effective components of chemical fertilizers in water is usually the standard for measuring the effectiveness of chemical fertilizers. The unit is the main indicator of the quality of chemical fertilizers, which refers to the percentage content of effective nutrients or their oxides in the fertilizer product, such as the percentage content of nitrogen, phosphorus, potassium, calcium, sodium, manganese, and sulfur.

[0003] After fertilizer production is completed, it is necessary to sample and test the fertilizer granules. The current sampling method is generally that the staff inserts a hand-held sampling device into the fertilizer granules, and the fertilizer granules fall into the collection tank of the sampling device. This sampling method is simple to operate and relatively convenient. However, when sampling multiple fertilizers, it is necessary to repeatedly pour out the collected fertilizers, which is inefficient. Chinese patent application number 201911190410.6 discloses a fertilizer granule sampler for calcium and magnesium fertilizer production. It can achieve the sampling of multiple fertilizer granules by setting multiple collection bottles. However, the number of collection bottles is limited, and the types of fertilizer granules that can be sampled are limited.

[0004] Improvements are needed to address the shortcomings of existing technologies. Summary of the Invention

[0021] The sampling cylinder 1 has multiple partitions 11 evenly distributed inside, and multiple retaining rings 12 are slidably sleeved on the outside of the sampling cylinder 1. The retaining rings 12 are C-shaped structures that are thinner at the bottom and thicker at the top, and have a notch on the front side. Each retaining ring 12 corresponds to one of the partitions 11, and multiple connecting pieces 13 are evenly distributed between the retaining rings 12 and the partitions 11. The sidewall of the sampling cylinder 1 has multiple sliding grooves evenly distributed. The connecting pieces 13 pass through the sliding grooves on the sampling cylinder 1, and one end of the connecting piece 13 is fixedly connected to the retaining ring 12, while the other end of the connecting piece 13 is fixedly connected to the partition 11. The sliding cylinder 2 is symmetrical from left to right. A second limiting cylinder 14 is provided, and a second push plate 15 is slidably connected inside the second limiting cylinder 14. A second push rod 16 is fixed on the second push plate 15. The two ends of the second push rod 16 pass through the two ends of the second limiting cylinder 14 respectively. One end of the second push rod 16 passes through the slide cylinder 2 and contacts the retaining ring 12. A button 17 is fixed to the other end of the second push rod 16. A second spring 18 is sleeved on the second push rod 16. One end of the second spring 18 is fixedly connected to the second push plate 15, and the other end of the second spring 18 is fixedly connected to the end of the second limiting cylinder 14 near the button 17.

[0022] In this embodiment, a mounting plate 19 is fixed to the upper end of the sampling cylinder 1, and a base 20 is fixed to the lower end of the sampling cylinder 1. A lead screw 21 and two positioning slide rods 22 are arranged between the mounting plate 19 and the base 20. The lead screw 21 and the slide rods 22 are evenly distributed around the sampling cylinder 1. The upper end of the slide rod 22 is fixedly connected to the lower side of the mounting plate 19, and the lower end of the slide rod 22 is fixedly connected to the base 20. At the same time, the slide rod 22 is slidably connected to the protruding part on the side edge of the slide cylinder 2.

[0023] In this embodiment, a hand-held part 1001 is provided at the lower end of the second baffle 10 to facilitate pushing and pulling the second baffle 10.

[0024] In this embodiment, the sidewall of the partition 11 is fitted with a rubber pad to increase the friction between the partition 11 and the inner wall of the sampling cylinder 1.

[0025] In this embodiment, the outer diameter of the retaining ring 12 is smaller than the inner wall diameter of the slide cylinder 2, which facilitates the retaining ring 12 passing through the slide cylinder 2.

[0026] In this embodiment, the base 20 is provided with a notch to facilitate the passage of the second baffle 10.

[0027] Working principle of the invention: When using the invention, pull button 17 to turn on the adjusting motor 23. The adjusting motor 23 drives the lead screw 21 to rotate clockwise, causing the slide cylinder 2 to slide downwards. When the second push rod 16 moves to below the lowest retaining ring 12, press button 17 to fix the second push rod 16, making the second push rod 16 close to the lower end of the retaining ring 12. Then, the adjusting motor 23 drives the lead screw 21 to rotate counterclockwise. Under the limiting action of the second push rod 16, the slide cylinder 2 drives the retaining ring 12 to move upwards until the retaining ring 12 drives the partition 11 to move above the feed inlet 101. At the same time, the second push rod 16 moves downwards. When the push plate 6 passes the first baffle 4, under the elastic force of the first spring 8, the first push plate 7 presses against the protruding structure of the first baffle 4, pushing the first baffle 4 to slide upward along the first guide rail 3, blocking the feed inlet 101. When the upper edge of the first baffle 4 contacts the upper end of the first guide rail 3, the upper end of the first guide rail 3 limits the first baffle 4 from continuing to move upward. The protruding structure of the first baffle 4 presses against the first push plate 7 and compresses the first spring 8 until the first push plate 7 slides above the protruding structure of the first baffle 4. After sampling, the button 17 is released, and the motor 23 drives the lead screw 21 to rotate counterclockwise. As the slide cylinder 2 moves upward, the second push rod 16 contacts the retaining ring 12 adjacent to the upper edge of the feed inlet 101. The second push rod 16 then slides upward along the side of the retaining ring 12, squeezing the second spring 18 until it moves to the upper side of the retaining ring 12. Then, the adjusting motor 23 drives the lead screw 21 to rotate clockwise, causing the second push rod 16 to contact the upper side of the retaining ring 12. The retaining ring 12 pushes the partition 11 downward. Simultaneously, when the first push plate 7 passes the first baffle 4, the first push plate 7 contacts the protruding structure of the first baffle 4, pushing the first baffle 4 downward. The protruding structure of plate 4 presses against the first push plate 7 and compresses the first spring 8 until the first push plate 7 slides below the protruding structure of the first baffle 4 until the lower edge of the first baffle 4 contacts the lower end of the first guide rail 3, opening the feed inlet 101. At this time, the fertilizer particles enter the sampling cylinder 1 through the feed inlet 101. Then, the partition 11 above the feed inlet 101 is moved downward in sequence through the above steps to sample the fertilizer particles in batches and separate them through the partition 11. After the sampling is completed, the second baffle 10 is slid downward to gradually open the discharge port and take out the fertilizer particles between the partitions 11 in sequence.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
