Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a crusher for straw maturation. Background Art

[0002] At present, the amount of discarded biomass straw resources in China reaches 700 million tons each year. A large amount of straw is burned on the spot because it cannot be properly recycled and disposed of. This not only causes serious environmental pollution and fire hazards, but also causes a huge waste of resources. Biomass raw materials such as crop straw and fruit tree branches are a kind of usable resource and a green energy, which can be used in fields such as incineration power generation.

[0003] Existing Chinese patent: A straw crusher, patent number: CN206380331U. The straw crusher of the utility model only needs one motor and a set of pulleys to drive the rotating shaft and the blade to rotate, so as to achieve the purpose of crushing the straw, which greatly reduces the power consumption of the crusher. At the same time, the crushing effect of the crusher is better, the particle size of the crushed material is uniform, and the discharge speed of the material can also be guaranteed.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: the blade of the above crusher can only rotate unidirectionally along the rotation direction of the shaft, which not only makes it easy for the straw to be entangled on the shaft, but also has a low crushing efficiency. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a crusher for straw maturation, which solves the technical problem that the blades of the above-mentioned crusher can only rotate unidirectionally along the rotating direction of the shaft, which not only easily causes the straw to be entangled on the shaft, but also has low crushing efficiency.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A straw ripening crusher comprises a crushing barrel, an internal meshing gear ring is fixedly installed inside the crushing barrel, a tripod is fixedly installed on the top end of the internal meshing gear ring, and three second gears are evenly rotatably installed on the bottom end of the tripod; the three second gears are distributed at 120 degrees and are all meshed with the internal meshing gear ring, a first gear is fixedly installed on the top end of the tripod, a rotating shaft is fixedly installed on the bottom end of the three second gears, and a plurality of blades are fixedly installed on the outer side wall of the rotating shaft; the plurality of blades on the three rotating shafts are staggered, a motor is fixedly installed inside the crushing barrel, and a third gear is fixedly installed on the bottom end of the motor; the third gear is meshed with the first gear, a magnetic attraction ring is installed on the bottom end of the crushing barrel, a filter is fixedly installed inside the magnetic attraction ring, a stabilizing frame is rotatably installed on the top end of the crushing barrel; the stabilizing frame is rotatably connected to the three rotating shafts.

[0010] Preferably: a lower hopper is fixedly mounted on the side end of the crushing barrel.

[0012] (III) Beneficial effects

[0013] 1. Put the straw into the crushing barrel through the lower hopper, and the motor starts to drive the third gear to rotate. The third gear drives the tripod to rotate by meshing with the first gear. When the tripod rotates, it will drive the three second gears to rotate along the inner meshing gear ring. Since the inner meshing gear ring is meshed with the three second gears, the second gears will rotate while rotating inside the inner meshing gear ring. The second gear drives the lower shaft to rotate around the axis of the tripod at the same time, and the multiple blades installed on the shaft will cut and crush the straw inside the crushing barrel. The multiple blades will tear the straw while cutting. By allowing the three shafts to rotate around the axis of the tripod while rotating, the straw inside the crushing barrel is torn and cut, thereby avoiding the entanglement of the straw and improving the crushing efficiency.

[0014] 2. The crushed straw fragments will be filtered out by the filter, and the large particles of straw will be left in the crushing barrel for further crushing. After the crushing is completed, the large particles of hard debris will remain in the crushing barrel. The magnetic ring can be removed by pulling the magnetic ring, and the large particles of debris in the crushing barrel can be taken out. The straw fragments can be filtered through the filter, thereby ensuring that the crushed straw can meet the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS

The straw is put into the crushing barrel through the lower hopper, and the motor starts to drive the third gear to rotate. The third gear drives the tripod to rotate by meshing with the first gear. When the tripod rotates, it drives the three second gears to rotate along the inside of the internal meshing gear ring. Since the internal meshing gear ring is meshed with the three second gears, the second gear will rotate while rotating inside the internal meshing gear ring. The second gear drives the lower shaft to rotate on its own while rotating around the axis of the tripod. Multiple gears installed on the shaft The blades will cut and crush the straw inside the crushing barrel, and multiple blades will tear the straw while cutting. By allowing the three shafts to rotate around the axis of the tripod while rotating on their own, the straw inside the crushing barrel is torn and cut, thereby avoiding the entanglement of the straw and improving the crushing efficiency. The crushed straw fragments will be filtered out by the filter, and large particles of straw will be retained in the crushing barrel for further crushing. When the crushing is completed, large and hard debris will remain in the crushing barrel. The magnetic ring can be removed by pulling the magnetic ring, and the large particles of debris inside the crushing barrel can be taken out. The straw fragments are filtered through the filter, thereby ensuring that the crushed straw meets the use requirements.

[0022] Example

The overall idea is as follows:

[0024] In view of the problems existing in the prior art, the utility model provides a straw ripening crusher, comprising a crushing barrel 1, an internal meshing gear ring 2 is fixedly installed inside the crushing barrel 1, a tripod 3 is fixedly installed on the top of the internal meshing gear ring 2, and three second gears 5 are evenly rotatably installed on the bottom end of the tripod 3; the three second gears 5 are distributed at one hundred and twenty degrees and are all meshed with the internal meshing gear ring 2, a first gear 4 is fixedly installed on the top of the tripod 3, and a rotating shaft 6 is fixedly installed on the bottom ends of the three second gears 5.

[0025] A plurality of blades 7 are fixedly mounted on the outer wall of the rotating shaft 6 ; the plurality of blades 7 on the three rotating shafts 6 are arranged in a staggered manner; a motor 8 is fixedly mounted inside the crushing barrel 1 , and a third gear 9 is fixedly mounted on the bottom end of the motor 8 ; the third gear 9 is meshed with the first gear 4 .

[0026] A magnetic ring 11 is installed at the bottom end of the crushing barrel 1, and a filter screen 12 is fixedly installed inside the magnetic ring 11. A stabilizing frame 15 is rotatably installed at the top of the crushing barrel 1; the stabilizing frame 15 is rotatably connected to the three rotating shafts 6, a lower hopper 13 is fixedly installed at the side end of the crushing barrel 1, and a supporting frame 14 is fixedly installed at the bottom end of the crushing barrel 1.

[0027] Working principle:

[0028] The first step is to put the straw into the crushing barrel 1 along the lower hopper 13, and the motor 8 is started to drive the third gear 9 to rotate. The third gear 9 drives the tripod 3 to rotate by meshing with the first gear 4. When the tripod 3 rotates, it will drive the three second gears 5 to rotate along the inside of the internal meshing gear ring 2. Since the internal meshing gear ring 2 is meshed with the three second gears 5, the second gears 5 will rotate while rotating inside the internal meshing gear ring 2. The second gear 5 drives the lower rotating shaft 6 to rotate around the axis of the tripod 3 while rotating on its own. The multiple blades 7 installed on the rotating shaft 6 will cut and crush the straw inside the crushing barrel 1. The multiple blades 7 will tear the straw while cutting. By allowing the three rotating shafts 6 to rotate around the axis of the tripod 3 while rotating on their own, the straw inside the crushing barrel 1 is torn and cut, thereby avoiding the entanglement of the straw and improving the crushing efficiency.

[0029] In the second step, the crushed straw fragments will be filtered out by the filter 12, and the large particles of straw will be left in the crushing barrel 1 to continue to be crushed. When the crushing is completed, the large particles of hard debris will remain in the crushing barrel 1. The magnetic ring 11 can be pulled off to remove the large particles of debris in the crushing barrel 1, and the straw fragments are filtered through the filter 12, thereby ensuring that the crushed straw can meet the use requirements.
