Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of compound fertilizer processing, specifically to a feeding and breaking machine for compound fertilizer processing. BACKGROUND

[0002] Compound fertilizer refers to the fertilizer containing two or more than two main nutrient elements (nitrogen N, phosphorus P, potassium K). These fertilizers can provide multiple nutrients required for crop growth, thereby optimizing the nutritional status of plants, promoting healthy growth and increasing yield. During the production and processing of compound fertilizer, a breaking machine is needed to break the large pieces of compound fertilizer raw materials into smaller particles for subsequent processing.

[0003] The patent with the announcement number CN218251951U discloses a feeding and breaking device for biological compound fertilizer processing, which comprises a feeding pipe, a servo motor is arranged at one end of the feeding pipe, a rotating shaft is installed in the feeding pipe through a shaft coupling at the output end of the servo motor on one side, springs are welded on the outer periphery of the rotating shaft, and breaking blocks are welded at the free ends of the springs, and breaking cylinders are welded on the outer periphery of the breaking blocks. When the breaking blocks and the breaking cylinders break the materials in the feeding pipe, the springs can deform due to their good deformation ability, so that when the breaking blocks and the breaking cylinders directly knock on the inner wall of the feeding pipe, the springs will deform and produce a certain skew angle, thereby preventing the inner wall of the feeding pipe from being knocked for a long time to form pits, so as to ensure that the materials will not be left after being conveyed, and the device is suitable for being widely promoted and used.

[0004] However, the breaking device in the above-mentioned technology still has the following problems: although the use of deformable and bendable springs to support the breaking blocks and the breaking cylinders can effectively prevent the inner wall of the feeding pipe from being knocked for a long time to form pits, in the process of breaking and processing the compound fertilizer raw materials, the raw materials may be stuck in the gaps of the springs, which prevents the springs from restoring the original deformation, and thus the breaking blocks and the breaking cylinders cannot be normally reset, affecting the smooth progress of the breaking and processing, and reducing the efficiency of the breaking and processing.

[0023] As Figures 1 to 5 The main improvement point of the present application is to improve the stability of spring 4 during breaking operation, as shown in Figures 1 to 5 When the compound fertilizer raw material enters the feeding pipe 1, the servo motor 2 drives the connecting shaft 3 to rotate, the connecting shaft 3 drives the high-speed rotation of the plurality of springs 4 and the broken piece 5 at the end of the spring 4 in the inside of the feeding pipe 1, so as to crush the compound fertilizer raw material, in this process, the outside of the spring 4 can be closed by the protective sleeve 6, so as to avoid the compound fertilizer raw material and the broken raw material from being stuck in the gap of the spring 4, and ensure that the spring 4 can smoothly rebound after bending deformation during the breaking operation, so that the spring 4 can continuously and stably perform the breaking operation, and the stability of the compound fertilizer breaking processing is improved.
