Description

Technical Field

[0001] The utility model relates to the technical field of mixed fertilizer production, in particular to an automatic feeding device for mixed fertilizer. Background Art

[0002] Blended fertilizer, also known as BB fertilizer or dry mixed fertilizer, is a fertilizer containing any two or three of the three nutrients of nitrogen, phosphorus and potassium. It is made from unit fertilizer or compound fertilizer through simple mechanical mixing. There is no significant chemical reaction during the mixing process. The production technology of blended fertilizer is simple. In many countries, blended fertilizer needs to be packaged and stored for a period of time. Therefore, the storage performance of the product is very important. All raw materials should be dry, uniform in particles, and high in strength to prevent the product from absorbing water, agglomerating and separating particles during storage and transportation.

[0003] Existing automated feeding equipment for blended fertilizers often uses a main belt conveyor, which cooperates with multiple auxiliary belt conveyors to transport various raw materials to the main belt conveyor and then send them into the feeding pool together. During the transportation process, the impurity particles contained in the raw materials cannot be filtered, which reduces the quality of the finished product of the blended fertilizer. At the same time, after the blended fertilizer is mixed, the collection of the blended fertilizer is time-consuming and labor-intensive, which affects the subsequent feeding work of the equipment and results in low feeding efficiency of the equipment.

[0004] To this end, we designed an automatic feeding equipment for blending fertilizers. Utility Model Content

The diameter of the cylinder 2 is larger than the diameter of the second hole. A rectangular hole is provided at the bottom of the cylinder 2. A filter plate 7 is installed in the rectangular hole. The filter plate 7 is connected to the collection plate 5. The collection plate 5 is provided with a strip hole. A cleaning brush 8 moves in the strip hole. The cleaning brush 8 is connected to a push-pull handle 9. The cover 6 is rotated to make both ends of the cylinder 2 closed to prevent a large amount of dust from being generated when pouring raw materials. The raw materials are poured into the cylinder 2 through the feed hopper 4. The raw materials continuously enter the cylinder 2. Under the weight of the raw materials, The screening frame 3 rotates, and the first hole and the second hole on the screening frame 3 filter impurities in the raw material. The first hole on the fan plate divides the fine impurities and large particle impurities in the raw material. A space is formed between two adjacent fan plates. The raw material is divided into different spaces by multiple fan plates, so that the amount of raw material in each space is small, thereby improving the impurity screening effect in the raw material. The fine impurities, large particle impurities and the raw material cannot pass through the first hole on the fan plate. The large particle impurities directly fall into the ring through the second hole during the flipping of the screening frame 3. The large particle impurities in the ring are removed by manually opening the cover 6, and the fine impurities move to the filter plate 7 under the flipping action of the screening frame 3. The holes on the filter plate 7 allow the fine impurities to pass directly and block the raw material. The fine impurities fall onto the collecting tray 5, and the cleaning brush 8 is driven to move by manually operating the push-pull handle 9, and the cleaning brush 8 removes the fine impurities on the collecting tray 5.
