[0028] like Figure 1 As shown, a straw disassembling and shredding device comprises a frame 1 and a disassembling component 2 and a shredding component 3 arranged on the frame 1 , wherein the outlet end of the disassembling component 2 is connected to the inlet end of the shredding component 3 .

[0029] like Figure 2 As shown, the scattering component 2 includes a scattering box 21, a scattering shaft 22, a scattering knife 23 and a transportation mechanism 24. Several of the scattering knives 23 are arranged on the scattering shaft 22, and multiple scattering shafts 22 are arranged from the inlet end to the outlet end in the scattering box 21 in sequence from high to low. The transportation mechanism 24 is arranged at the bottom of the scattering box 21, and the outlet end of the scattering box 21 is connected to the kneading component 3.

[0030] The frame 1 is in a stepped shape, the kneading component 3 is placed on a lower layer of the stepped frame 1 , and the breaking component 2 is placed on a higher layer of the frame 1 .

[0031] The scattering box 21 is trapezoidal, the bottom of the scattering box 21 is perpendicular to the kneading box 31 , and the hypotenuse of the trapezoidal scattering box 21 forms an angle with the kneading box 31 .

[0032] In some embodiments, multiple breaking up shafts 22 are parallel to each other, and multiple breaking up shafts 22 are on an inclined plane. The breaking up shafts 22 are arranged from high to low in sequence from the entrance end to the exit end in the breaking up box 21, so that after the round (square) bale of straw enters the breaking up box 21, it is driven by the transportation mechanism 24 and first passes through the breaking up shaft 22 at the highest point. The breaking up knife 23 arranged on the breaking up shaft 22 disassembles and breaks up the round (square) bale of straw as the breaking up shaft 22 continuously rotates, and then passes through the breaking up shaft 22 and the breaking up knife 23 that are shorter than the previous height for further rotation, disassemble and break up, from high to low, until the round (square) bale of straw is completely disassembled and broken up.

[0033] In some embodiments, five breaking shafts 22 are arranged from high to low to complete the disassembly and breaking of round (square) bundles of straw, and the disassembly and breaking are carried out from high to low in sequence. After the disassembly and breaking, the straw enters the silk kneading box 31 for the silk kneading process.

[0034] like Figure 3As shown, the transport mechanism 24 includes a spike rod 241, a transport chain 242, a transport main shaft 243, a transport slave shaft 245 and a transport motor 244. The transport main shaft 243 is arranged at one end of the bottom of the scattering box 21 close to the silk kneading component 3, and the transport slave shaft 245 is arranged at the other end of the bottom of the scattering box 21. The transport chain 242 includes two and parallel arrangements, one end of one of the transport chains 242 is meshed with one end of the transport main shaft 243 for transmission, and the other end is meshed with one end of the transport slave shaft 245 for transmission, one end of the other transport chain 242 is meshed with the other end of the transport main shaft 243 for transmission, and the other end is meshed with the other end of the transport slave shaft 245 for transmission, and the two ends of the spike rods 241 are arranged between the two transport chains 242, and the transport motor 244 is connected to the transport main shaft 243 for transmission.

[0035] One transport chain 242 is located at one end of the bottom plate of the scattering box 21, and the other transport chain 242 is located at the other end of the bottom plate of the scattering box 21. One end of the transport chain 242 is meshed with the transport main shaft 243, and the other end of the transport chain 242 is meshed with the transport slave shaft 245. The two transport chains 242 are arranged in parallel, and the bottom plate of the scattering box 21 is located in the space between the transport chains 242. The bottom of the spike tooth rod 241 is in a tooth shape, and the teeth on the two adjacent spike tooth rods 241 are staggered to prevent the straw from slipping through the gap of the previous tooth shape during the process of moving forward and being stopped by the next tooth.

[0036] The scattering component 2 further includes a scattering inlet 25 , and the scattering inlet 25 is arranged at an end of the scattering box 21 away from the kneading component 3 .

[0037] The round (square) bale of straw enters from the scattering feed port 25 and falls directly to the bottom of the scattering box 21. The transport motor 244 starts to drive the transport main shaft 243 to rotate. The rotation of the transport main shaft 243 drives the meshing transport chain 242 to roll. The transport chain 242 drives the meshing transport slave shaft 245 to rotate. During the transmission process, the transport chain 242 will drive the spike tooth rod 241 connected to it to move toward the kneading component 3. The straw that has been broken up by the scattering shaft 22 and the scattering knife 23 is transported to the kneading feed port 39 of the kneading component 3 through a number of spike tooth rods 241 to be kneaded.

[0038] In some embodiments, the scattering shaft 22 can be manually adjusted to rotate, or it can be electrically driven by connecting to the output end of the scattering shaft motor 26. The scattering component 2 also includes a scattering shaft motor 26, which is arranged on the outside of the scattering box 21, and the scattering shaft motor 26 is transmission-connected to multiple scattering shafts 22.

[0039] The scattering component 2 further includes a blocking curtain 27 , and the blocking curtain 27 is arranged between the scattering inlet 25 and the scattering box 21 .

[0040] like Figure 4 As shown, the kneading component 3 includes a kneading box 31, and the kneading component 3 also includes a kneading inlet 39, which is arranged on the top of the kneading box 31 and communicated with the kneading box 31, and the kneading inlet 39 is communicated with the discharge end of the scattering box 21. The scattered straw enters the kneading box 31 from the kneading inlet 39 and is repeatedly kneaded, so that the straw becomes soft.

[0041] like Figure 5 As shown, a main thread kneading shaft 32, a kneading movable knife 33, a kneading auxiliary shaft 34 and a kneading fixed knife 35 are arranged in the kneading box 31, the top of the kneading box 31 is connected to the outlet end of the breaking up box 21, several of the kneading movable knives 33 are arranged on the main thread kneading shaft 32, the kneading main shaft 32 is arranged in the kneading box 31, several of the kneading fixed knives 35 are arranged on the kneading auxiliary shaft 34, and several of the kneading auxiliary shafts 34 are axially arranged on the outside of the kneading box 31, and several of the kneading fixed knives 35 pass through the kneading box 31 and are interspersed with the kneading movable knives 33.

[0042] A plurality of kneading knives 33 are arranged in multiple rows around the kneading main shaft 32, and each row of kneading knives 33 is arranged from one end of the kneading main shaft 32 to the other end. The kneading knives 33 in each row are spaced at a certain distance, and the kneading knives 33 in two adjacent rows are staggered, which can ensure that the straw will not miss from the interval between the single row of kneading knives 33 as much as possible. If the straw misses from the interval between one row of kneading knives 33 and is not kneaded, it will be kneaded by the next row of staggered kneading knives 33. Each kneading knives 33 is composed of two hammers spaced at a certain distance.

[0043] like Figure 6 As shown, the kneading fixed knife 35 is arranged on the kneading auxiliary shaft 34, and multiple kneading auxiliary shafts 34 can be arranged around the kneading box 31, which can better achieve the kneading effect. The kneading fixed knife 35 passes through the inner wall of the kneading box 31, and the position of the kneading fixed knife 35 is fixed. The kneading fixed knife 35 is arranged at a certain interval, and each kneading fixed knife 35 is interspersed with the kneading movable knife 33. The straw is subjected to the clockwise force applied by the kneading movable knife 33 in the kneading box 31, and is also subjected to the resistance of the kneading fixed knife 35. In this way, forces in different directions are repeatedly applied to the straw, making the straw softer.

[0044] In some embodiments, the silk kneading main shaft 32 can be driven manually or electrically driven by connecting to the output end of the silk kneading shaft motor 36. The silk kneading component 3 also includes a silk kneading shaft motor 36, which is arranged on the frame 1 and is connected to the silk kneading shaft in a transmission manner.

[0045] The kneading component 3 also includes a throwing blower 37, which is arranged at the discharge end of the kneading box 31. The purpose of setting the kneading blower is that although the straw will fall into the kneading box 31 for kneading by its own gravity under the action of the transportation mechanism 24 after being broken up by the breaking component 2, the scattered straw is relatively light, or a small amount of straw is hung on the parts in the breaking component 2 during the disassembly and breaking process, and may not fall smoothly into the kneading box 31. After the throwing blower 37 is turned on, the airflow generated by the blower generates a certain adsorption force, and the disassembled and broken straw is sucked into the kneading box 31 for kneading.

[0046] like Figure 7 As shown, the kneading component 3 also includes a sieve plate 38, which is arranged at the bottom of the kneading box 31. The sieve plate 38 is a curved arc plate, and the radius of the sieve plate 38 is the same as the radius of the kneading box 31. The sieve plate 38 is just spliced ​​with the arc plates on both sides of the bottom of the kneading box 31 to form a cylinder with an open top. There are several holes on the sieve plate 38. During the kneading of the straw, the impurities such as awns, ears, soil, sand, etc. in the straw are removed through the holes on the sieve plate 38 by their own gravity. After dust removal, the straw silk is cleaner, which is conducive to the subsequent utilization of raw materials.
