Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a raw material crushing device for the preparation of amino acid bio-fertilizer. Background Technology

[0002] Crop straw is rich in organic matter and is also an important carrier of organic elements. In the process of processing organic fertilizer, crop straw is both a primary and auxiliary raw material. Processing straw into organic fertilizer requires fermentation and decomposition to achieve sterilization and pest control. Therefore, the straw needs to be crushed and mixed to promote the uniform and easily absorbed distribution of various nutrients in the organic matter. This necessitates the use of crushing equipment to crush the crop straw.

[0003] For example, Chinese utility model patent CN218736091 U discloses a raw material crushing device for bio-fertilizer production, including a machine body shell, a rotatable drive shaft installed above the inner cavity of the machine body shell, a crushing blade sleeved on the outside of the drive shaft, a support rod installed at the bottom of the inner cavity of the machine body shell, a blade holder movably connected above the support rod, a grinding blade installed on the outside of the blade holder, a drive shaft passing through the support rod connected to the lower end of the blade holder, a second motor connected to the other end of the drive shaft to drive the drive shaft to rotate, and a grinding base movably arranged in the inner cavity of the machine body shell.

[0004] In the above solution, although the electric push rod can drive the grinding base to move up and down, thereby changing the distance between the grinding base and the grinding blade to meet the needs of different straw powder fineness, the equipment can only grind one type of straw powder fineness at a time. When different finenesses of straw powder are needed, the equipment needs to be adjusted back and forth, which is quite troublesome. In addition, the fineness of different straw powders is not much different, and it is difficult for the electric push rod to be accurately adjusted to the corresponding distance. Utility Model Content

[0005] To address the technical problem that the above-mentioned solutions cannot simultaneously process straw powder of various finenesses, this utility model provides a raw material crushing device for preparing amino acid bio-fertilizer.

[0006] This utility model is achieved using the following technical solution: a raw material crushing device for preparing amino acid bio-fertilizer, comprising a crushing barrel, a fixed frame fixedly connected to the outside of the crushing barrel, a feed inlet at the top of the crushing barrel, three crushing boxes installed inside the crushing barrel, through holes of different fineness opened on the side wall of each crushing box, a fixed column that can move up and down inside each crushing box, a crushing blade for crushing straw installed at the top of the fixed column, a bottom block fixedly connected to the bottom inner side of each crushing box, and the fixed column sliding through the middle of the bottom block, and three discharge ports fixedly connected to the bottom inner side of the crushing barrel, the discharge ports being located directly below the crushing boxes.

[0007] The above technical solution involves setting up three crushing chambers with different through holes inside the crushing barrel to allow the equipment to process straw powder of different finenesses simultaneously.

[0008] As a further improvement to the above solution, a crossbar is fixed to the inner wall of the feed inlet, and a cutting blade for preliminary cutting of the straw is provided at the top of the crossbar.

[0009] Through the above technical solution, the cutting blade can break up and disperse the straw in its original state, thus avoiding affecting the subsequent crushing.

[0010] As a further improvement to the above solution, an electric push rod is fixedly connected to the top center of the three discharge ports, and a connecting frame is fixedly connected to the output end of the electric push rod. The connecting frame is fixedly connected to the bottom end of each fixed column.

[0011] Through the above technical solution, the electric push rod drives the fixed column to move up and down, which not only improves the uniform crushing of straw by the crushing blade set at the top of the fixed column, but also improves the leakage of the crushed straw powder from the through hole opened in the crushing box.

[0012] As a further improvement to the above solution, a limiting box is provided on the outside of the crushing box, and the limiting box is fixed to the inner side wall of the crushing barrel.

[0013] Through the above technical solution, the setting of the limiting box allows the straw powder leaking from the through hole to fall directly into the discharge port, preventing the leaked straw powder from falling onto the bottom of the crushing barrel. At the same time, each crushing barrel is equipped with a limiting box on the outside, which can also prevent straw powder of different fineness from mixing.

[0014] As a further improvement to the above solution, a fixing block is provided between the top of the crushing box and the top of the inner side of the crushing barrel, and the fixing block is provided with an arc-shaped concave surface at the top of the crushing box.

[0015] With the above technical solution, the fixed blocks at the top of the crushing box are all provided with arc-shaped concave surfaces, which can ensure that all the initially chopped straw falls into the crushing box and prevent the straw from accumulating on the top of the fixed blocks.

[0016] As a further improvement to the above solution, the outer surfaces of both the connecting frame and the crossbar are set to be arc-shaped.

[0017] The above technical solution avoids the accumulation of straw or straw powder on the top of the connecting frame and crossbar, thus preventing waste of resources and avoiding subsequent cleaning.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention allows the equipment to process straw powder of different fineness simultaneously by setting three pulverizing boxes with different through holes inside the pulverizing barrel. An electric push rod drives the fixed columns of different sizes at both ends to move up and down, which not only improves the uniform pulverization of straw by the pulverizing blades set at the top of the fixed columns, but also improves the leakage of the pulverized straw powder from the through holes in the pulverizing boxes.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Please combine Figures 1-5 This embodiment of an amino acid bio-fertilizer preparation raw material crushing device includes a crushing barrel 1, a fixing frame 2 fixedly connected to the outside of the crushing barrel 1, a feed inlet 3 provided at the top of the crushing barrel 1, three crushing boxes 4 installed inside the crushing barrel 1, through holes 5 of different fineness opened on the side wall of each crushing box 4, a fixing column 6 that can move up and down is provided inside each crushing box 4, a crushing blade 7 for crushing straw is installed at the top of the fixing column 6, a bottom block 8 is fixedly connected to the bottom inner side of each crushing box 4, and the fixing column 6 slides through the middle of the bottom block 8, and three discharge ports 9 are fixedly connected to the bottom inner side of the crushing barrel 1, the discharge ports 9 being located directly below the crushing box 4.

[0029] The straw raw material is transported to the feed inlet 3 by the conveying component. Due to gravity, the straw raw material falls into the crushing barrel 1 and is distributed into the three crushing boxes 4 installed in the crushing barrel 1. At this time, the fixed column 6 that moves up and down drives the crushing blade 7 installed at the top to crush the straw in the crushing box 4. At the same time, the crushed straw powder will leak out from the through hole 5 opened in the crushing box 4 and fall out from the discharge port 9.

[0030] The number of crushing blades 7 installed on the top of the fixed column 6 inside different crushing boxes 4 is not the same. The larger the size of the through hole 5, the fewer the corresponding number of crushing blades 7.

[0031] Combination Figure 2 A crossbar 10 is fixed to the inner wall of the feed inlet 3, and a cutting blade 11 for preliminary cutting of straw is provided at the top of the crossbar 10.

[0032] By fixing a crossbar 10 to the inner wall of the feed inlet 3, and setting a cutting blade 11 at the top of the crossbar 10, the straw in its original state can be crushed and broken up, thus avoiding affecting the crushing of the straw inside the crushing box 4.

[0033] Combination Figure 4 An electric push rod 12 is fixedly connected to the top center of the three discharge ports 9. A connecting frame 13 is fixedly connected to the output end of the electric push rod 12. The connecting frame 13 is fixedly connected to the bottom end of each fixed column 6.

[0034] The electric push rod 12 drives the fixed column 6 to move up and down and slide in the middle of the bottom block 8. This not only improves the uniform crushing of straw by the crushing blade 7 set at the top of the fixed column 6, but also improves the leakage of the crushed straw powder from the through hole 5 opened in the crushing box 4.

[0035] Combination Figure 3 and Figure 4 A limit box 14 is provided on the outside of the crushing box 4, and the limit box 14 is fixed to the inner wall of the crushing barrel 1.

[0036] By setting a limiting box 14 in the crushing box 4 and fixing the limiting box 14 to the inner wall of the crushing barrel 1, the straw powder leaking from the through hole 5 can only fall into the discharge port 9 under the limitation of the limiting box 14, thus preventing the leaked straw powder from falling to the bottom of the crushing barrel 1. At the same time, each crushing box 4 is equipped with a limiting box 14 on the outside, which can also prevent straw powder of different fineness from mixing.

[0037] Combination Figure 3 A fixing block 15 is provided between the top of the crushing box 4 and the top of the inner side of the crushing barrel 1. The fixing block 15 is provided with an arc-shaped concave surface at the top of the crushing box 4.

[0038] The fixed blocks 15 are all equipped with arc-shaped concave surfaces at the top of the crushing box 4, which ensures that all the initially chopped straw falls into the crushing box 4 and prevents the straw from accumulating on the top of the fixed blocks 15.

[0039] Combination Figure 2 and Figure 4 The outer surfaces of both the connecting frame 13 and the crossbar 10 are rounded.

[0040] The outer surfaces of the connecting frame 13 and the crossbar 10 are designed as arc surfaces, which can prevent straw or straw powder from accumulating on the top of the connecting frame 13 and the crossbar 10, thus avoiding waste of resources and subsequent cleaning.

[0041] The implementation principle of the raw material crushing device for preparing amino acid bio-fertilizer in this application embodiment is as follows:

[0042] Before crushing, the conveying component is installed above the feed inlet 3. At this time, the straw raw material is transported sequentially through the conveying component. The straw raw material falls into the crushing bucket 1 due to gravity. When the straw raw material passes the cutting blade 11 installed at the top of the crossbar 10, it will be broken up and crushed.

[0043] Then, the crushed and broken straw material falls into the three crushing boxes 4 through the arc-shaped concave fixing block 15. Because the three crushing boxes 4 have through holes 5 of different sizes on their side walls, the equipment can produce straw powder of different fineness.

[0044] At this time, the electric push rod 12 fixed to the top of the discharge port 9 is opened, which drives the connecting frame 13 to move up and down inside the crushing barrel 1. The up and down movement of the connecting frame 13 can synchronously drive the three fixed columns 6 to move up and down, so that the crushing blade 7 installed at the top of the fixed column 6 moves up and down and rotates, so that the crushed and dispersed straw can be crushed evenly. In addition, the up and down movement of the fixed column 6 can also improve the leakage of the crushed straw powder from the through hole 5 opened in the crushing box 4.

[0045] Because each crushing box 4 has a limiting box 14 fixed to the inner wall of the crushing barrel 1, the straw powder leaking from each crushing box 4 can only fall into the discharge port 9 installed at the bottom of its own crushing box 4 after being restricted by the limiting box 14.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
