Description

Technical Field

[0001] The utility model relates to the technical field of straw production equipment, in particular to a straw recycling and processing device for agricultural environmental protection. Background Art

[0002] As agricultural waste, straw has long been mainly treated by methods such as incineration and stacking. These methods not only waste resources but also cause environmental pollution. Traditional straw recycling devices mostly use a simple crushing function. Although they can crush the straw into small particles, the crushed straw still takes up a large space and is inconvenient to store and transport. In addition, these traditional methods cannot adjust the crushing effect and compression density when processing straw, resulting in certain limitations during use.

[0003] The prior art, such as the Chinese utility model patent with announcement number CN202322319185, discloses a "straw crushing and recycling device", which arranges a driving mechanism in a crushing box, a plurality of feeding mechanisms are respectively arranged on the driving mechanism, a crushing compression assembly is connected to a crushing box discharge port, a fixed end of the discharge assembly is arranged below the crushing box, and a crushing assembly is arranged in the crushing box to automatically bring the straw thrown into the crushing box for crushing, thereby avoiding the phenomenon of straw accumulation and blockage, and improving efficiency without stopping the machine for unblocking. The crushed straw is compressed, recovered and then discharged, simplifying the process and shortening the recycling processing time. However, this structure has defects, namely, it is difficult to adjust the compression density of the straw. At the same time, the humidity of the straw will affect the compactness of the straw block, thereby causing the straw block to spread during transportation, and the compactness and dryness of the straw will affect the fuel efficiency of the straw after the straw is used as fuel.

[0043] Example 3

[0044] Working principle: When recycling straw, the user puts the straw into the crushing chamber 12, and the blade 21 in the crushing chamber 12 rotates under the drive of the motor 25 to crush the straw. The crushed straw particles pass through the sieve plate 14 and enter the extrusion chamber 13. The larger straw particles are rolled up by the blade 21 again and crushed again. The straw particles entering the extrusion chamber 13 fall downward and are squeezed by the rolling extrusion cylinder 22. The moisture in the squeezed straw particles is squeezed out and passes through the through holes 221 on the outside of the extrusion cylinder 22. The straw particles are blocked by the filter screen 222 and move downward as the extrusion cylinder 22 rotates. The straw moisture entering the extrusion cylinder 22 enters the drainage groove 223 and is guided out of the housing 1 by the drainage groove 223. In addition, when squeezing the silage straw, the nutrient-rich juice can also be collected, thereby making full use of the straw resources.

[0045] The squeezed straw particles fall downward into the recovery pipe 31, and the straw particles are located in the push frame 35. When the straw particles in the recovery pipe 31 gradually accumulate until the straw particles reach the top of the recovery pipe 31 and block the infrared signal generated by the infrared sensor 315, the control panel 33 controls the second push rod 36 to push the push block 37 to move, and the push block 37 pushes the straw particles to move and cooperates with the adjustment plate 381 to squeeze the straw particles. After being squeezed, the straw particles become straw blocks. When the squeezing force on the straw blocks is greater than the thrust of the spring 385 on the adjustment plate 381, the straw The straw block is pushed by the push block 37 and also pushes the adjustment plate 381 to one side. After the adjustment plate 381 moves to one side, it drives the adjustment rod 3811 to one side, so that the adjustment rod 3811 touches the adjustment switch 312, so that the adjustment switch 312 sends a signal, causing the second push rod 36 to retract. At the same time, the first push rod 34 pushes the push frame 35 to move outward. The push frame 35 slides in the discharge port 311, thereby pushing the straw block into the recovery pipe 31, thereby separating the straw block from the inside of the recovery pipe 31, and the push frame 35 returns to its original position under the contraction of the first push rod 34.

[0046] When adjusting the thrust of the adjustment plate 381, the user rotates the nut 384 to make the nut 384 move to one side, so that the nut 384 squeezes the spring 385, and the spring 385 contracts between the nut 384 and the limit plate 314, so that the spring 385 provides a greater thrust to the adjustment plate 381, thereby making the straw block push the adjustment plate 381 with a greater thrust, thereby adjusting the tightness of the straw block.
