Description

Technical Field

[0001] The utility model belongs to the field of organic fertilizer production devices, and in particular relates to a straw composting device used for organic fertilizer production. Background Art

[0002] The process of straw composting is to uniformly mix straw with fermentation agent and then let it stand and ferment under suitable conditions. In the process of straw composting, the straw needs to be crushed first, and then the straw needs to be uniformly mixed with the fermentation agent. The existing straw composting device mainly combines the effects of crushing straw, uniformly mixing straw and its fermentation agent, and sealing and fermenting the mixed fermentation product. However, the existing straw composting device of this type can only complete the tasks of crushing straw and then mixing straw and its fermentation agent in steps, and due to the small amount of fermentation agent added, after the fermentation agent is concentratedly added to the straw, it must be stirred for a long time to make the agent uniformly distributed in the straw pile. The above problems will affect the processing efficiency. In this regard, the utility model provides a straw composting device for organic fertilizer production. Utility Model Content

[0003] The purpose of the utility model is to provide a straw composting device for producing organic fertilizer in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] The utility model provides a straw composting device for producing organic fertilizer, comprising a processing barrel, a feed box detachably connected to the processing barrel, and a corresponding sealing cover. A cutter for chopping straw is provided in the feed box, and a detachable feeding mechanism is provided below the feed box. The feeding mechanism is used to evenly mix a straw fermentation agent into the straw.

[0006] The feeding mechanism includes a material box and the material box can rotate synchronously with the cutter. Several discharge ports are opened in the side wall of the material box, and a shielding member is provided on the outside of the material box. The material box cooperates with the shielding member to open the discharge port when the straw enters the processing barrel.

[0007] As a further optimization scheme of the present invention, the shielding member includes a bracket arranged under the material box, and a plurality of side panels corresponding to the discharge ports are provided on the outside of the bracket. A mounting column is provided under the material box, and the bracket is rotatably connected to the mounting column through a torsion spring.

[0008] As a further optimization scheme of the present invention, a number of feed openings distributed in a circular array and aligned one by one are provided in the top plate and the bottom plate of the feed box, a rotating rod passing through the bottom plate is provided in the feed box, and a driving member for driving the rotating rod to rotate is provided on the feed box, and the cutting knife sleeve is provided on the outside of the rotating rod.

[0009] As a further optimization solution of the present invention, a material tube is provided on the top of the material box, and the material tube is screwed together with the rotating rod through a thread.

[0010] As a further optimization solution of the present invention, a screen is provided in the discharge port of the material box.

[0011] The beneficial effects of the present invention are:

[0012] The straw composting device for organic fertilizer production achieves the effect of chopping straw during the feeding process by arranging a cutter in the feeding box on the processing barrel. By arranging a material box that can rotate synchronously with the cutter and a side plate that elastically rotates with the material box, the material box and the side plate can be gradually dislocated during the rotation, thereby opening the discharge port on the outside of the material box, thereby outputting the straw fermentation agent while chopping the straw. The straw fragments and the straw fermentation agent can be evenly mixed during the feeding process. After the feeding is completed, it only needs to cover the sealing plate to start static fermentation. The operation method is convenient and efficient, and the burden of manual labor is low.

[0017] 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.

[0018] Example 1

[0019] like Figure 1-3 As shown, the straw composting device for organic fertilizer production of this embodiment includes a processing barrel 1 with a side-rotating bottom cover at the bottom of the processing barrel 1, a feed box 2 and a corresponding sealing cover 3 detachably connected to the processing barrel 1, a cutter 5 for chopping straw is provided in the feed box 2, and a detachable feeding mechanism is provided below the feed box 2 for uniformly mixing a straw fermentation agent into the straw;

[0020] The feeding mechanism includes a material box 6 and the material box 6 can rotate synchronously with the cutter 5. Several discharge ports are opened in the side wall of the material box 6, and a shielding member is provided on the outside of the material box 6. The material box 6 cooperates with the shielding member to open the discharge port when the straw enters the processing barrel 1.

[0021] After the straw is put into the feed box 2, it will be chopped by the cutter 5 and then fall into the processing barrel 1. In this process, the whole connected by the shielding member and the feed box 6 gradually opens the discharge port during rotation, and the straw fermentation agent in the feed box 6 can be gradually thrown out of the feed box 6 under the action of centrifugal force and mixed into the continuously falling straw fragments, so as to achieve the effect of uniform mixing of the straw fragments and the straw fermentation agent during the feeding process. Then, it is only necessary to cover the sealing cover 3, and the straw and its fermentation agent can be left to ferment in the processing barrel 1. After the fermentation is completed, the fermentation product can be output by rotating the bottom cover and the inner cavity of the device can be flushed. The operation is convenient and efficient.

[0022] Preferably, the shielding member includes a bracket 10 arranged below the material box 6, and a plurality of side plates 9 corresponding to the discharge port are provided on the outside of the bracket 10. A mounting post 11 is provided below the material box 6, and the bracket 10 is rotatably connected to the mounting post 11 by a torsion spring. In the initial state, the side plates 9 completely block the discharge port, and the straw fermentation agent in the material box 6 will not leak out. When the material box 6, the mounting post 11, the bracket 10 and the side plates 9 are connected as a whole and start to rotate, the discharge port is gradually opened and remains open during the rotation process. The straw fermentation agent in the material box 6 can be thrown out under the action of centrifugal force and evenly mixed into the straw fragments falling from the outside. The faster the rotation speed of the cutter 5 and the material box 6, the smaller the opening range of the discharge port, and the higher the output efficiency of the straw fermentation agent. After stopping, the whole connected by the side plates 9 and the bracket 10 will return to the initial position under the action of the torsion spring.

[0023] The specific process of the gradual opening of the discharge port is: when the material box 6 just starts to rotate, the rotation speed of the whole connected by the side plate 9 and the bracket 10 will be lower than that of the material box 6, and then gradually accelerates to the same speed as the material box 6. During this process, the torsion spring is compressed, and the whole connected by the side plate 9 and the bracket 10 and the material box 6 rotate relative to each other, and the side plate 9 and the corresponding discharge port will be misaligned, thereby achieving the effect of opening the discharge port. Subsequently, the whole connected by the material box 6, the mounting column 11, the bracket 10 and the side plate 9 rotate synchronously and at a uniform speed. In this state, the bracket 10 and the side plate 9 maintain a uniform rotation state under the action of the torsion spring force and wind resistance. Therefore, the higher the rotation speed and the greater the wind resistance, the greater the compression amplitude of the torsion spring and the greater the opening amplitude of the discharge port.

[0024] Preferably, a plurality of feed openings are provided in the top and bottom plates of the feed box 2, distributed in a circular array and aligned one by one. A rotating rod 4 is provided in the feed box 2 and passes through the bottom plate. A driving member for driving the rotating rod 4 is provided on the feed box 2, and a cutter 5 is sleeved on the outside of the rotating rod 4. The straw is fed through the feed openings, and the operator does not need to put his hands into the feed box 2, which is safe to operate.

[0025] Preferably, a material tube 7 is provided on the top of the material box 6, and the material tube 7 is screwed together with the rotating rod 4 through a thread, and the material box 6 can be disassembled and assembled by rotating it, which is convenient for adding materials or cleaning residual materials.

[0026] Preferably, a screen 8 is provided in the discharge port of the material box 6, which can further scatter the straw fermentation agent during the process of outputting it from the material box 6 and avoid concentrated output of the straw fermentation agent, which is beneficial to improving the mixing uniformity of the straw and its fermentation agent.

[0027] 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.
