Description

Technical Field

[0001] This utility model relates to the technical field of spiral feeding equipment, and in particular to an automatic feeding device for liquid fertilizer production. Background Technology

[0002] Liquid fertilizer manufacturing is the process of dissolving or suspending nutrients in water to form a liquid fertilizer that can be applied directly. Its core is to ensure that nutrients are evenly distributed and easily absorbed by plants through reasonable raw material ratios, stirring, dissolving, and reaction steps.

[0003] Adding granular or powdered raw materials to a mixing tank with water for stirring and ensuring the full reaction of all components is the primary step in liquid fertilizer production. The production process mainly uses a screw conveyor to add raw materials to the mixing tank. Most existing screw conveyors have a fixed tilt angle, which is not conducive to efficiently and energy-savingly adding raw materials to equipment at different heights. Some screw conveyors with angle adjustment functions, after tilt angle adjustment, have a non-vertical discharge port, which cannot properly match the mixing tank inlet. Some require the addition of a power device to the discharge port to adjust the discharge port angle and ensure accurate feeding. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Specific embodiments of the automatic feeding equipment for liquid fertilizer production provided by this utility model:

[0025] Please see Figure 1-6 An automatic feeding device for liquid fertilizer production includes an inclined screw conveyor 1 and a frame 2 that supports the rotation of the lower end of the screw conveyor 1. The frame 2 is welded together from several horizontal and vertical bars.

[0026] The frame 2 is provided with a bearing 9 to support the rotation of the lower end of the screw conveyor 1. There are two bearings 9 symmetrically arranged on both sides of the lower end of the screw conveyor 1. A transverse rotating shaft is symmetrically connected to both sides of the lower end of the screw conveyor 1, and the rotating shafts on both sides are supported by the two bearings 9.

[0027] The shaft seat 9 is connected to the frame 2 by bolts. The frame 2 is provided with a transverse slot 10 that mates with the bolts of the shaft seat 9. The slot 10 is parallel to the projection line of the center line of the screw conveyor 1 on the horizontal plane. The transverse slot 10 allows the position of the shaft seat 9 to be changed. After the position of the shaft seat 9 is determined, the bolts are tightened to stabilize the lower end of the screw conveyor 1.

[0028] A hopper 11 is mounted on the frame 2. The hopper 11 is an inverted cone shape, wider at the top and narrower at the bottom. The lower end of the hopper 11 is connected to the feed inlet on the upper side of the lower end of the screw conveyor 1 via a flexible hose 12. The discharge port at the lower end of the hopper 11 is inclined for easy discharge. The flexible hose 12 is a corrugated pipe, and both ends of the flexible hose 12 are connected to the feed inlets of the hopper 11 and the screw conveyor 1 via flanges. The flexible hose 12 is deformable. As the lower end of the screw conveyor 1 moves laterally with the shaft seat 9 and the angle of the screw conveyor 1 changes, the flexible hose 12 can adapt to the deformation, allowing the raw material in the hopper 11 to pass smoothly into the screw conveyor 1.

[0029] The upper discharge port of the screw conveyor 1 is connected to the feed cylinder 3 via a flexible cylinder 7. In this embodiment, the flexible cylinder 7 is a cloth cylinder. When the angle between the position of the feed cylinder 3 and the position of the screw conveyor 1 changes, the flexible cylinder 7 can deform. In order to ensure that the cloth cylinder has good throughput, a rigid ring 8 is provided in the middle of the cloth cylinder. The rigid ring 8 ensures the throughput area in the middle of the cloth cylinder and expands the inner throughput area of ​​the upper and lower ends when the cloth cylinder is deformed, thereby ensuring that the raw material output by the screw conveyor 1 enters the feed cylinder 3 and then enters the mixing tank for liquid fertilizer production.

[0030] The feed cylinder 3 is connected to an upper connecting rod 4 that is hinged to the screw conveyor 1. There are two upper connecting rods 4, which are symmetrically located on both sides of the upper end of the screw conveyor 1 and the feed cylinder 3. The lower end of the upper connecting rod 4 is fixedly connected to the feed cylinder 3, and the upper end of the upper connecting rod 4 is hinged to the outer side of the upper end of the screw conveyor 1. The axis of the feed cylinder 3 is parallel to the upper connecting rod 4.

[0031] The rotating part of the screw conveyor 1 is connected to a vertical lower connecting rod 5. Specifically, there are two lower connecting rods 5, which are respectively connected to two shaft seats 9; the upper end of the lower connecting rod 5 is fixedly connected to the shaft seat 9.

[0032] A connecting rod frame 6 is hinged between the upper connecting rod 4 and the lower connecting rod 5. The connecting rod frame 6 includes two parallel connecting rods, and several intermediate rods are connected between the two connecting rods. The upper and lower ends of the connecting rods are respectively hinged to the lower ends of the upper connecting rod 4 and the lower ends of the lower connecting rod 5.

[0033] The screw conveyor 1, upper connecting rod 4, lower connecting rod 5, and connecting rod frame 6 form a parallelogram mechanism, making upper connecting rod 4 and lower connecting rod 5 parallel, and connecting rod frame 6 parallel to screw conveyor 1. Since lower connecting rod 5 is vertically positioned and connected to shaft seat 9, regardless of the tilt angle of screw conveyor 1, upper connecting rod 4 always maintains the same vertical position as lower connecting rod 5. Therefore, when the angle of screw conveyor 1 changes, the discharge cylinder 3 always remains vertical, facilitating its connection with the feed inlet of the mixing tank. This avoids the situation where the discharge cylinder 3 is difficult to extend into or correspond to the feed inlet of the mixing tank after tilting, preventing raw material spillage and ensuring accurate feeding.

[0034] To ensure the stability of the screw conveyor 1 during both the feeding and moving states, a slide block 15 is vertically slidably connected to the frame 2. The slide block 15 is equipped with positioning bolts 16, and the frame 2 is vertically and evenly provided with a number of positioning holes 17 that mate with the positioning bolts 16. The slide block 15 is rotatably connected to a clamping structure that holds the lower part of the screw conveyor 1.

[0035] The slide 15 has a square ring structure and moves vertically up and down along the outside of the vertical rod of the frame 2. There are two slides 15, located on both sides of the screw conveyor 1, and the two slides 15 are supported by a clamping structure and move up and down synchronously. The slides 15 are connected to positioning bolts 16 by threads, and the positioning bolts 16 pass through the side wall of the slide 15. Positioning holes 17 are evenly spaced on the vertical rod of the frame 2. When the positioning bolts 16 are inserted into the positioning holes 17 at different heights, the lower part of the screw conveyor 1 is fixed by the clamping structure.

[0036] The clamping structure includes a carrier plate 13 rotatably connected to the slide 15. A U-shaped clamp 14 is connected to the carrier plate 13. The U-shaped clamp 14 has external threads at both ends and is connected to nuts through the external threads. After determining the position of the clamping structure, the nuts are tightened to clamp and hold the U-shaped clamp 14 and the carrier plate 13 tightly on the lower outer side of the screw conveyor 1. Shafts are provided on both sides of the carrier plate 13, and the shafts are rotatably connected to the slide 15 to adapt to changes in the tilt angle of the screw conveyor 1.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
