Description

Technical Field

[0001] The utility model relates to the technical field of straw processing, in particular to a crushing device for processing crop straw. Background Art

[0002] Biomass includes organic matter produced by plants through photosynthesis (such as plants, animals, and their excrement), garbage, and organic wastewater. Biomass energy comes from the sun, making it a form of solar energy. Biomass is the primary absorber and reservoir of solar energy, concentrating it through photosynthesis and storing it in organic matter. Biomass is widely used in the production of pelleted feed, fuel, and other applications.

[0003] The existing technology requires straw biomass to be crushed before it is used, but there is no limiting and correcting device for the straw when it is fed into the crushing device. When the straw falls vertically into the crushing device, it is parallel to the crushing blade and cannot be effectively cut and crushed. This will cause the crushing to fail to meet the use standards, and it is easy for the straw to fall into the machine and not be completely crushed, which will cause the straw discharge port to be blocked, affecting the overall work efficiency.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a pulverizing device for processing crop straw includes a pulverizing frame 1 and a bottom plate 2. Two pulverizing rollers 11 arranged side by side are fixedly installed inside the pulverizing frame 1. Multiple groups of pulverizing blades 12 are fixedly installed on the outside of the pulverizing rollers 11. A feeding frame 13 is fixedly installed at the bottom end of the pulverizing frame 1. A guide plate 14 is fixedly installed at the bottom end of the inner wall of the feeding frame 13. The bottom end of the feeding frame 13 is fixedly connected to the bottom plate 2 through a supporting leg. The top end of the bottom plate 2 is located at the feeding frame 13 and is fixedly installed with a limiting assembly 4 through a support column 3. The limiting assembly 4 includes a U-shaped frame 41, a side plate 42, a conveying roller 43, a conveyor belt 44 and a baffle 45. The side plate 4 One end of the support column 41 is located above the center between the two crushing rollers 11. The blocking bar 45 and the conveying roller 43 are parallel to the crushing roller 11. The U-shaped frame 41 is fixedly installed on the top of the support column 3 with the open end facing upward. The side plates 42 are in two groups and are fixedly installed on both sides of the top of the U-shaped frame 41. The two sides of the side plates 42 form an extension portion 421. The conveying roller 43 is movably installed between the extension portions 421 on both sides. The conveyor belt 44 is movably installed on the outside of the two conveying rollers 43. The blocking bars 45 are in multiple groups and are fixedly installed on the outside of the conveyor belt 44. A discharge portion 451 is formed between two adjacent blocking bars 45. The area of ​​each discharge portion 451 is equal.

[0026] Example 2

[0027] like Figures 1 to 3 As shown, the U-shaped frame 41 and the side plate 42 are both inclined, and the side close to the crushing frame 1 is the bottom end.

[0028] Specifically: through the inclined U-shaped frame 41 and side plate 42, the conveyor belt 44 is tilted accordingly, and the straw to be crushed placed on the surface of the conveyor belt 44 slides along the surface of the conveyor belt 44 to the baffle 45 due to the action of gravity. Due to the blocking and limiting of the baffle 45, the straw is relatively parallel to the baffle 45 at this point, and there is no need for manual correction by the staff, thereby improving the use effect.

[0029] like Figure 1 As shown, the guide plate 14 is U-shaped and its opening faces upward.

[0030] Specifically, the waste materials are concentrated and fall on the center of the bottom end of the inner wall of the U-shaped material guide plate 14, which reduces the size of the waste discharge port and is conducive to collecting the waste materials.

[0031] like Figure 1 As shown: a vibration block is fixedly installed at the bottom end of the guide plate 14.

[0032] Specifically, the discharge of processed materials on the guide plate 14 can be accelerated to prevent accumulation.

[0033] Principle of use: The straw to be crushed is placed on the discharge part 451 on the conveyor belt 44, and the baffles 45 on both sides are used as the limit standard to place the straw parallel to it. During the operation of the conveyor belt 44, the above-mentioned discharge part 451 is gradually replaced by the discharge part 451 adjacent to it. The staff places the second batch of straw to be crushed on the adjacent discharge part 451 in the same way as above. The batches of straw are in a state parallel to the baffles 45 and fall into the two crushing rollers 11 for crushing, so that the straw and the crushing rollers 11 can be made parallel, ensuring that the crushing blades 12 are perpendicular to the straw and thus fully cut and crush it, preventing the uncrushed straw from falling into the discharge port and causing blockage, thereby improving the use effect. The cut and crushed straw falls onto the guide plate 14 for guidance and discharge, and the straw crushing is completed; when the U-shaped When the frame 41 and the side plates 42 are both inclined, the surface of the conveyor belt 44 is inclined accordingly. Since the lower side of the conveyor belt 44 is located above the crushing roller 11, the straw to be crushed placed on the surface of the conveyor belt 44 slides along the surface of the conveyor belt 44 to the baffle 45 due to gravity. Due to the blocking and limiting of the baffle 45, the straw is relatively parallel to the baffle 45 at this point, and there is no need for manual correction by the staff, which further improves the use effect and the use efficiency. When the guide plate 14 is U-shaped, the processed straw is concentrated and accumulated at the center of the bottom end of the inner wall of the U-shaped guide plate 14, reducing the size of the waste discharge port, which is conducive to collecting waste. When a vibration block is provided at the bottom end of the guide plate 14, the material on the surface of the guide plate 14 is more likely to slide down due to vibration, which prevents accumulation and improves practicality.

[0034] It's important to note that when selecting and preparing treatment solutions, it's important to choose one that reacts chemically with the pollutants in the exhaust gas, based on their type and properties. Common solutions include acids, bases, oxidizing agents, and reducing agents. The selected solutions are then mixed into an absorption solution in a specific ratio to ensure sufficient absorption capacity and stability.

[0035] The foregoing description is merely a detailed description of specific embodiments of the present invention, intended to enable those skilled in the art to understand and implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but is intended to conform to the broadest scope consistent with the principles and novel features claimed herein.
