Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production equipment, in particular to a feeding device for producing water-soluble fertilizers. Background Art

[0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can dissolve quickly in water and is more easily absorbed by crops. Its absorption and utilization rate is relatively high. More importantly, it can be used in facility agriculture such as sprinkler irrigation to achieve water-fertilizer integration and save water, fertilizer and labor.

[0003] There are two major types of raw materials for the production of water-soluble fertilizers: liquid raw materials and solid raw materials. Usually, employees need to unpack the solid raw materials one bag at a time and pour them into the feeding hopper. The feeding speed is very slow and consumes a lot of manpower costs. There is also a risk of injuring the operating employees when manually breaking the bags. Therefore, a device that can break the bags and feed materials is needed to assist production. For this purpose, we propose a feeding device for the production of water-soluble fertilizers. Utility Model Content

[0012] Preferably, a hinge shaft is installed between the top of the rear cover plate and the bag transfer bin, and the rear cover plate can be rotated left and right through the hinge shaft. A counterweight bar is provided at the bottom of the rear cover plate, so that the rear cover plate always remains vertical under the action of gravity.

[0013] Preferably, the size of the serrations on the two rightmost blades of the bag breaking knives is twice the size of the remaining serrations, the three leftmost blades of the bag breaking knives have a blade body that is one-third larger in volume than the remaining blade bodies, and the three blades there are all blunt blades, and the leftmost bag breaking knife is installed in the inner cavity of the left ramp plate, and one-third of the blade body protrudes upward.

[0016] 1) Driven by the conveyor belt, the bagged raw materials are dragged to the left, and the bottom of the bag is dragged on the sieve plate. The bottom of the bag is cut after contacting the bag-breaking knife. The arc-shaped blade reduces the chance of the bag being scratched. At the same time, the serrated blade can cut the bag faster and more smoothly. The raw materials in the bag are quickly squeezed and expanded at the break under the action of gravity, and fall down into the lower hopper to complete the feeding work;

[0017] 2) The sawtooth on the far right is larger, which can create a larger hole in the bag at the first time. The blade on the back side continues to scrape the hole, which can speed up the scraping of the raw materials at the hole.

[0030] Furthermore, a transparent protective glass is provided in the middle of the rear cover 13, and sealing strips are provided around the rear cover 13, and the sealing strips are recessed to the right and abut against the left side wall of the bag-passing bin 12. A handle is fixed to the middle of the rear side of the rear cover 13 by screws, and a hinge shaft is installed between the top of the rear cover 13 and the bag-passing bin 12, so that the rear cover 13 can rotate left and right through the hinge shaft, and a counterweight bar is provided at the bottom of the rear cover 13;

[0031] Furthermore, a sieve plate 16 is provided at the bottom of the inner cavity of the bagging bin 12, the lower hopper 11 is provided below the bagging bin 12, the sieve plate 16 is located above the lower hopper 11, the sieve plate 16 is concave downward, and the left and right ends are downwardly inclined plates;

[0032] Furthermore, a lifting device 2 is provided at the upper part of the inner cavity of the bagging bin 12, and the lifting device 2 includes a conveyor belt 21 and a fixing frame 22. The conveyor belt 21 is arranged horizontally and located above the sieve plate 16. The fixing frames 22 are arranged equidistantly on the outer side of the conveyor belt 21. A fixing plate is provided on one side of the fixing frame 22 close to the conveyor belt 21, and the fixing plate is fixed to the surface of the conveyor belt 21 by screws.

[0033] The fixed frame 22 is fixed with hooks 23 arranged at equal intervals, and the hook mouth direction of the hook 23 is consistent with the rotation direction of the conveyor belt 21;

[0034] Further, a control box 14 is installed on the right side of the chassis 1, and the control box 14 should include a running button, an emergency stop button and a speed adjustment button of the conveyor belt 21;

[0035] Furthermore, a bag-breaking knife 17 is arranged transversely in the middle of the sieve plate 16. The blade of the bag-breaking knife 17 is an ellipse that protrudes upward. Except for the three blades on the far left, the rest of the bag-breaking knife 17 is provided with serrations. The serrations on the blades of the two bag-breaking knives 17 on the far right are twice the size of the remaining serrations. The blades of the three bag-breaking knives 17 on the far left are one-third larger than the blades of the remaining blades, and the three blades at this location are all blunt.

[0036] The leftmost bag-breaking knife 17 is installed in the inner cavity of the left ramp plate, and protrudes upward by one third of the knife body;
