Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, specifically to a biological organic fertilizer mixing device. Background Technology

[0002] Against the backdrop of the coordinated advancement of green agricultural development and ecological environmental protection, bio-organic fertilizer, as a key product for replacing traditional chemical fertilizers, improving soil quality, and enhancing the quality of agricultural products, is experiencing continuous expansion in its industrial scale. With the implementation of policies promoting large-scale breeding and the resource utilization of agricultural waste, the output of organic raw materials such as livestock and poultry manure, straw, and mushroom residue has increased significantly, providing ample raw materials for bio-organic fertilizer production. However, this has also placed higher demands on raw material processing and mixing processes—how to efficiently blend organic materials with significantly different properties has become the core factor determining the stability of bio-organic fertilizer efficacy.

[0003] Existing technologies use drum-type mixing devices for mixing. The core of the drum-type bio-organic fertilizer mixing device is to use the rotational motion of the inclined drum to drive the material to complete a cycle of "lifting-sprinkling-tumbling" inside the drum, ultimately achieving uniform mixing of organic materials, microbial agents, and conditioners.

[0004] However, although drum mixers achieve continuous production, they lack the active mixing action of forced shearing or spiral pushing, resulting in longer mixing time and lower mixing efficiency. Utility Model Content

[0005] This invention addresses the technical problem of drum mixers lacking the active mixing action of forced shearing or spiral pushing, resulting in long mixing times and low mixing efficiency, and provides a biological organic fertilizer mixing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biological organic fertilizer mixing device, comprising: a mixing drum, the mixing drum being inclined, both ends of the mixing drum being rotatably connected to a frame, the mixing drum being connected to a rotational power source, a cover plate one being fastened to the higher end of the mixing drum, and a cover plate two being fastened to the lower end of the mixing drum, both cover plate one and cover plate two being connected to the frame, cover plate two not covering the lower part of the mixing drum, multiple dispersing shafts being rotatably connected to cover plate one and cover plate two, all dispersing shaft axes being located on the same plane as the mixing drum axis, dispersing blades being connected to the dispersing shafts, a lifting plate being connected to the inner wall of the mixing drum, and cover plate one being connected to a feeding mechanism.

[0007] Preferably, the dispersing blades of adjacent dispersing shafts are staggered, and the adjacent dispersing shafts are connected by belt drive.

[0008] Preferably, the minimum horizontal gap between the end of the dispersing blade and the lifting side of the mixing drum is greater than the maximum diameter of the raw material agglomeration, while the minimum horizontal gap between the other end of the dispersing blade and the falling side of the mixing drum is less than the maximum diameter of the raw material agglomeration.

[0009] Preferably, the feeding mechanism includes multiple screw conveyors, and the conveying housing of the screw conveyors is connected to the mixing drum through a hole in the cover plate.

[0010] Preferably, an input gear is connected to the outside of the mixing drum, and the input gear meshes with the output gear of the power source.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. After the raw materials are lifted up by the lifting plates, they fall onto the dispersing blades. Under the action of the falling impact force and the shearing force of the dispersing blades, the raw material clumps are quickly broken up and mixed, and then roll down the inclined surface of the mixing drum. This greatly increases the mixing speed, eliminates the need for a long mixing time, and allows for a larger tilt angle of the mixing drum, which greatly increases the mixing uniformity and mixing efficiency.

[0012] 2. All dispersing blades rotate in the same direction, and the intersection of the dispersing blades on adjacent dispersing shafts rotates in opposite directions, which greatly increases the shearing force on the raw materials and makes the dispersing effect better.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] The following is in conjunction with the appendix Figure 1-3 This embodiment describes a biological organic fertilizer mixing device, comprising: a mixing drum 1, which is inclined and rotatably connected to a frame 2 at both ends; the mixing drum 1 is connected to a rotational power source; a cover plate 3 is fastened to the higher end of the mixing drum 1, and a cover plate 4 is fastened to the lower end of the mixing drum 1; both cover plate 3 and cover plate 4 are connected to the frame 2; cover plate 4 does not cover the lower part of the mixing drum 1; multiple dispersing shafts 5 are rotatably connected to cover plate 3 and cover plate 4; the axis of all dispersing shafts 5 is located on the same plane as the axis of the mixing drum 1; dispersing blades 6 are connected to the dispersing shafts 5; a lifting plate 7 is connected to the inner wall of the mixing drum 1; and cover plate 3 is connected to a feeding mechanism 9.

[0019] The rotational power drives the mixing drum 1 to rotate. The feeding mechanism 9 injects different raw materials through the holes 3 of the cover plate. The mixing drum 1 lifts the raw materials by the lifting plate 7 and they fall onto the dispersing blade 6. The power drives the dispersing blade 6 to rotate through the dispersing shaft 5. Under the action of the falling impact force and the shearing force of the dispersing blade 6, the raw materials are lifted and dispersed repeatedly and quickly mixed. The raw materials roll down the inclined surface of the mixing drum 1 and are discharged through the lower part of the cover plate 4. In this way, the mixing speed is greatly increased, and a longer mixing time is not required. The tilt angle of the mixing drum 1 can be allowed to be larger, which greatly increases the mixing uniformity and mixing efficiency.

[0020] The dispersing blades 6 of adjacent dispersing shafts 5 are staggered, and adjacent dispersing shafts 5 are connected by belt drive 8.

[0021] The power is driven by the belt drive 8 to make all the dispersing blades 6 rotate in the same direction. The intersection of adjacent dispersing blades 6 rotates in opposite directions, which greatly increases the shearing force on the raw materials and makes the dispersing effect better.

[0022] The minimum horizontal gap between the dispersing blade 6 at one end and the lifting side of the mixing drum 1 is greater than the maximum diameter of the raw material agglomeration, while the minimum horizontal gap between the dispersing blade 6 at the other end and the falling side of the mixing drum 1 is less than the maximum diameter of the raw material agglomeration.

[0023] This way, the raw materials won't get stuck when the material is lifted, and they won't be spilled when it falls back down.

[0024] The feeding mechanism 9 includes multiple screw conveyors, and the conveying shell of the screw conveyor is connected to the mixing drum 1 through the cover plate 3 holes.

[0025] An input gear 10 is externally connected to the mixing drum 1, and the input gear 10 is meshed with the output gear of the power source.
