Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reaction devices, in particular to a straw aerobic composting reaction device with a crushing and cutting structure. Background Art
[0002] With the continuous growth of my country's economy, people's demand for agricultural products is increasing, resulting in a large amount of agricultural waste such as crop straw and vegetable straw. Randomly discarded and piled agricultural waste not only affects the environment and becomes a breeding ground for germs and mosquitoes, but also causes non-point source pollution of the water environment due to the loss of nitrogen and phosphorus nutrients. The current social treatment methods are generally incineration, landfill and composting; among them, composting is the most ecological method.
[0003] However, the current composting device has the following problems:
[0004] Before composting the straw, the longer straw needs to be crushed and then introduced into a single reaction tank. However, since some straw is not crushed completely, it is easy to get stuck at the tank mouth when it is introduced into the reaction tank, which requires time for secondary processing and cannot meet the efficient processing needs. Utility Model Content
[0005] In view of the shortcomings of the prior art, the utility model provides a straw aerobic composting reaction device with a crushing and cutting structure, which overcomes the shortcomings of the prior art and effectively solves the problem that some straws are not completely crushed and are easily stuck at the tank mouth when introduced into the reaction tank, resulting in time-consuming secondary processing and failure to meet efficient processing requirements.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A straw aerobic composting reaction device with a crushing and cutting structure comprises a reactor body, a fixed box is plugged and fixed on the top of the reactor body, a feed hopper is fixed on the top of the fixed box, crushing mechanisms are connected to the inner walls on both sides of the fixed box, and the crushing mechanisms comprise arc rods distributed at equal distances, connecting plates fixed at both ends of the arc rods, connecting blocks fixed to the outer walls of one side of the two connecting plates away from each other, sliders fixed to the top and bottom of the connecting blocks, crushing rollers rotatably connected to the inner walls at both ends of the fixed box, and a driving motor connected to one end of the crushing rollers.
[0008] The cut straw is thrown into the feed hopper. When the straw enters the fixed box, the shorter straw falls into the reactor body from the gap between two adjacent arc-shaped rods, while the longer straw lies horizontally on the top of the two arc-shaped rods. The crushing roller is driven by the driving motor to rotate, and the rotating crushing roller cuts and crushes the longer straw again, making the straw shorter so that it can fall smoothly into the reactor body below.
[0009] Preferably, a first fixing block is fixed to an outer wall of one side of the fixing box, and a servo motor is installed at the bottom of the first fixing block.
[0010] The position of the crushing mechanism is fine-tuned by a servo motor.
[0011] Preferably, a screw rod is rotatably connected to the top of the first fixed block, and the bottom end of the screw rod is fixedly connected to the output shaft of the servo motor, and the screw rod and the connected connecting block form a threaded fit.
[0012] The servo motor drives the lead screw to rotate, and the rotating lead screw drives the threaded connection block to move.
[0013] Preferably, a second fixing block is fixed to the outer wall of the other side of the fixing box, and a sliding rod is fixed to the top of the second fixing block, and the sliding rod forms a sliding fit with the connected connecting block.
[0014] The connecting block slides along the slide bar.
[0015] Preferably, both outer walls of the fixed box are provided with openings adapted to the connection blocks, and both inner walls of the openings are provided with sliding grooves adapted to the sliders.
[0016] The connecting block moves along the opening on the fixed box, and the sliding block moves along the sliding groove to block the opening position to prevent broken straw from popping out of the opening.
[0017] Preferably, the outer diameter of the crushing roller is smaller than the inner diameter of the arc rod, and the blade thickness of the crushing roller is smaller than the distance between two adjacent arc rods.
[0018] The blade of the crushing roller rotates between two adjacent arc-shaped rods to crush and cut off the longer straws.
[0019] The beneficial effects of the utility model are:
[0020] By throwing the cut straw from the feed hopper and the straw into the fixed box, the shorter straw falls into the reactor body from the gap between two adjacent arc-shaped rods, while the longer straw lies horizontally on the top of the two arc-shaped rods. The crushing roller is driven by a driving motor to rotate, and the rotating crushing roller cuts and crushes the longer straw again to make the straw shorter so that it can fall smoothly into the reactor body below. This effectively solves the problem in the prior art that some straws are not completely crushed and are easily stuck at the tank mouth when introduced into the reaction tank, resulting in time-consuming secondary processing and failure to meet efficient processing requirements.

[0028] A first fixed block 5 is fixed to an outer wall of one side of the fixed box 2, and a servo motor 6 is installed at the bottom of the first fixed block 5. The position of the crushing mechanism 4 is finely adjusted by the servo motor 6. A screw rod 7 is rotatably connected to the top of the first fixed block 5. The bottom end of the screw rod 7 is connected and fixed to the output shaft of the servo motor 6. The screw rod 7 forms a threaded fit with the connected connection block 12. The servo motor 6 drives the screw rod 7 to rotate, and the rotating screw rod 7 drives the threaded connection block 12 to move.
[0029] A second fixed block 8 is fixed to the outer wall of the other side of the fixed box 2, and a sliding rod 9 is fixed to the top of the second fixed block 8. The sliding rod 9 forms a sliding fit with the connected connecting block 12, and the connecting block 12 slides along the sliding rod 9. The outer walls of both sides of the fixed box 2 are provided with openings adapted to the connecting block 12, and the inner walls at both ends of the opening are provided with sliding grooves adapted to the sliding block 13. The connecting block 12 moves on the fixed box 2 along the opening, and the sliding block 13 moves along the sliding groove to block the opening position to prevent the broken straw from popping out of the opening. The outer diameter specification of the crushing roller 14 is smaller than the inner diameter specification of the arc rod 10, and the blade thickness of the crushing roller 14 is smaller than the spacing between two adjacent arc rods 10. The blade of the crushing roller 14 rotates between two adjacent arc rods 10 to crush and cut longer straw.
[0030] Working principle:
[0031] During operation, the cut straw is put into the feed hopper 3. When the straw enters the fixed box 2, the shorter straw falls into the reactor body 1 from the gap between two adjacent arc-shaped rods 10, while the longer straw lies horizontally on the top of the two arc-shaped rods 10. The crushing roller 14 is driven by the driving motor 15 to rotate. The rotating crushing roller 14 cuts and crushes the longer straw again, making the straw shorter so that it can fall smoothly into the reactor body 1 below.
