Description

Technical Field

[0001] The utility model belongs to the field of fertilizer manufacturing equipment, and in particular relates to a device for making fertilizer by fermenting straw waste. Background Art

[0002] Straw and agricultural waste (such as livestock and poultry manure, vegetable waste, etc.) are both excellent raw materials for fertilizer production, and the two can be mixed and fermented to make fertilizer. During the manufacturing process, the straw and agricultural waste need to be crushed and mixed in turn, and an appropriate amount of water and fermentation bacteria need to be added as fermentation auxiliary materials. In order to ensure that the fermented product can fully react, in the initial stage of fermentation and during the fermentation process, it is necessary to solve the problems of uneven mixing of the fermented product, agglomeration of the fermented product, sedimentation of the liquid fermented product, and uneven overall temperature of the fermented product through stirring. Therefore, sufficient stirring can greatly improve the fermentation efficiency and improve the fermentation effect. In order to achieve the effect of self-stirring, the existing fermentation equipment mostly sets a single or grouped stirring piece in the fermentation chamber. The stirring angle of a single stirring piece is fixed, the efficiency is low, and when there is too much fermented product, it is easy to cause the problem of stirring omission. Although multiple groups of stirring pieces have a wider stirring range and higher efficiency, they will reduce the space utilization rate in the fermentation chamber and are costly. In response to the above problems, the present utility model proposes a device for fermenting fertilizer using straw waste. Utility Model Content

[0021] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-5 As shown, the device for fermenting straw waste into fertilizer in this embodiment includes a fermentation barrel 1 and a frame thereof. The fermentation barrel 1 is provided with a detachable barrel cover 2, and a stirring assembly is provided at the center of the fermentation barrel 1.

[0024] The stirring assembly includes a lifting plate 3 and a support plate 4 located directly below the lifting plate 3. A base 5 is provided below the support plate 4 for positioning and engaging with the fermentation barrel 1. Several folding plates distributed in a circular array are provided between the lifting plate 3 and the support plate 4. The folding plates can be folded symmetrically along the center line. A cylinder 12 for controlling the lifting and lowering of the lifting plate 3 is provided on the barrel cover 2.

[0025] When using this device for fermentation and fertilizer production, the crushed straw and agricultural waste are directly put into the fermentation barrel 1, and then an appropriate amount of water is injected into the fermentation barrel 1. After closing the fermentation barrel 1, the cylinder 12 is turned on to push the lifting plate 3 downward. Since the support plate 4 is positioned in cooperation with the base 5 and the fermentation barrel 1, the distance between the lifting plate 3 and the support plate 4 will gradually decrease, the folding plate will gradually be folded, and its center part will gradually protrude outward. When the cylinder 12 drives the lifting plate 3 to rise, the folding plate will gradually unfold to a state close to vertical, and its center part will gradually retract. Each folding and unfolding process can achieve the effect of stirring the fermented material at multiple angles, with high stirring efficiency and a wide coverage of the stirring effect, so that the fermented materials in different directions can be fully replaced, and the effect of evenly mixing the fermented materials can be achieved, which is conducive to improving the fermentation effect.

[0026] Preferably, the folding plate includes two movable plates 6 that are symmetrically distributed up and down. The distal ends of the two movable plates 6 are provided with connecting sleeves 9, and the proximal ends are also connected through the connecting sleeves 9. The connecting sleeves 9 are made of any one of elastic silicone, plastic and metal. During the folding and unfolding process of the folding plate, the connecting sleeves 9 at both ends and the middle can be adaptively deformed, which is highly flexible and durable.

[0027] Preferably, a plurality of through grooves 7 distributed in a linear array are provided in the movable plate 6 and a cutter 8 is provided in the through groove 7. When the fermented material is stirred, the fermented material can pass through the through grooves 7. During this process, the cutter 8 can break up the agglomerated or lumped fermented material, which is beneficial to improving the fluidity and density distribution uniformity of the fermented material, and further improving the fermentation effect.

[0028] Preferably, the detachable bottom cover of the fermentation barrel 1 is provided with several blocks 13, and the base 5 is provided with a slot that matches the block 13. The block 13 is rotatably and detachably connected to the base 5. After the whole formed by the stirring assembly and the base 5 is installed in place, the bottom cover of the fermentation barrel 1 is installed. After the block 13 is inserted into the fermentation barrel 1, it is rotated until it is clamped with the base 5, and then the bottom cover is fixed with bolts. Then, the whole formed by the support plate 4 and the base 5 can remain fixed during the repeated folding of the stirring assembly.

[0029] Preferably, a turntable 10 for carrying the stirring assembly is embedded in the barrel cover 2 and a driving member for controlling the turntable 10 is provided on the barrel cover 2. The support plate 4 is rotatably connected to the base 5, and the cylinder 12 is provided on the turntable 10. The stirring assembly as a whole can be folded and rotated at the same time, which can further improve the stirring and mixing efficiency. When in use, it is necessary to ensure that the rotation direction of the stirring assembly is the same as the rotation direction when the block 13 is engaged with the base 5.

[0030] Preferably, the driving member corresponding to the turntable 10 includes a gear ring 11 sleeved on the outside of the turntable 10, a gear meshing with the gear ring 11, and a motor driving the gear to rotate.

[0031] Preferably, the barrel cover 2 includes a mounting cover that is snap-fitted to the fermentation barrel 1 and a side flip cover that is rotatably connected to the mounting cover. The turntable 10 and its corresponding driving member are both located on the mounting cover. When in use, the stirring assembly is first installed in place and then the side flip cover is opened for loading.

[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
