Description

Technical Field

[0001] The invention relates to the technical field of carbon soil preparation, and in particular to a device and method for preparing cassava carbon soil. Background Art

[0002] Cassava belongs to the root crop, and the underground root is mainly harvested. The byproducts obtained after cassava harvest are mainly stems and old seed stems, with a large biomass. Plant stems, leaves, roots and other byproducts contain rich organic matter and nutrients necessary for plant growth and development such as nitrogen, phosphorus, and potassium. The use of plant stems, leaves, roots and other byproducts mixed with soil to prepare carbon soil can partially replace chemical fertilizers, reduce the amount of crop fertilizers, significantly improve the physical and chemical properties of the soil and the richness of microorganisms, and improve soil fertility. Carbon soil is fired at high temperature and has a strong killing effect on soil-borne diseases and pathogens. In addition, carbon soil has excellent air permeability and water retention, which is conducive to the growth and development of plant roots, thereby promoting the long-term sustainable development of agricultural ecosystems. Therefore, the use of cassava byproducts to prepare cassava carbon soil has good application prospects.

[0003] When preparing cassava carbon soil, the air-dried cassava by-product is crushed into broken roots less than 15 cm in length by a crusher, added to a stewing furnace and mixed with an appropriate amount of soil, and stewed to prepare cassava carbon soil. However, the rhizome of cassava is long and has many branches, and the rhizome after air-dried is brittle. It is easy for the branches on the cassava by-product to break during the crushing process. The broken branches will be ejected irregularly outward from the grinder, which is very dangerous. In addition, the branches of the cassava by-product will be ejected to the outside of the grinder and scattered when crushed, affecting its crushing effect.

DETAILED DESCRIPTION

[0028] Hereinafter, the embodiments will be described using the accompanying drawings. The same symbols are attached to the same parts in the drawings and their detailed description is appropriately omitted, and the different parts are described. In addition, the drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the ratio of the size between the parts, etc. may not be the same as the actual one. In addition, even when representing the same part, there is a case where the size and ratio are different from each other according to the drawing.

[0029] See also Figure 1-Figure 8The present invention provides a technical solution: a cassava carbon soil preparation device, comprising a crushing chamber 2, a primary crushing wheel 10 is arranged inside the crushing chamber 2, a third conveyor belt 12 is arranged at the bottom of the primary crushing wheel 10, a stewing furnace 3 is arranged at the rear side of the crushing chamber 2, a first feed port 4 for docking with the rear end of the third conveyor belt 12 is opened above the stewing furnace 3, a fixed frame 1 is fixedly connected to the front end of the crushing chamber 2, a first conveyor belt 8 is fixedly connected to the inside of the fixed frame 1, a pre-crushing and transporting mechanism is arranged inside the fixed frame 1, and the pre-crushing and transporting mechanism is used to pre-crush cassava by-products to reduce the collapse of cassava by-products during crushing;

[0030] When the above scheme is put into practical use, the discarded cassava stalks, old seed stems and other by-products are air-dried and put into the fixed frame 1, and the cassava by-products are preliminarily crushed by the pre-crushing and transportation mechanism inside the fixed frame 1. The crushed products enter the crushing chamber 2 again, and are crushed again by the first-level crushing wheel 10 and transported to the stewing furnace 3 through the third conveyor belt 12. An appropriate amount of soil is added to the stewing furnace 3 to match the cassava by-products entering the stewing furnace 3, and stewing is carried out inside the stewing furnace 3. After stewing, the cassava carbon soil can be taken out from the discharge port at the bottom of the stewing furnace 3. The advantage of this is that before the cassava by-products are crushed by the crushing chamber 2, the cassava by-products are preliminarily crushed by the pre-crushing and transportation mechanism, and the branches on the cassava by-products are cut off, so that when the cassava by-products enter the crushing chamber 2, they can all remain in a long strip shape to reduce bifurcation. At the same time, the cut branches will be sent to the crushing chamber 2 together with the rhizomes for crushing, ensuring that the collapse of the rhizomes during the crushing process is effectively reduced, so that the crushing effect of the cassava by-products is better.

[0031] As a further solution of the present invention, the pre-crushing and transporting mechanism includes a transmission crawler 14, which is rotatably arranged inside the fixed frame 1, and a plurality of rotating rollers 15 are arranged inside the transmission crawler 14, and both ends of the rotating rollers 15 are respectively rotatably connected to the inner wall of the fixed frame 1, and a plurality of fixed plates 18 distributed at equal intervals are fixedly connected to the transmission crawler 14, and a sliding seat 17 is slidably sleeved on the outside of the fixed plate 18, and the sliding seat 17 is fixedly connected to a fixed spring for resetting the sliding seat 17, and an extrusion block 16 is fixedly connected to the top of the sliding seat 17, and a transmission wheel 19 is rotatably connected inside the fixed frame 1, and the transmission wheel 19 and the rotating roller 15 are jointly connected to a transmission belt 21 The side wall of the transmission wheel 19 is fixedly connected with a lever 20, and the inner wall of the fixed frame 1 is slidably connected with a first tooth plate 31 and a second tooth plate 34 respectively. The first tooth plate 31 and the second tooth plate 34 are meshed with a transmission gear 33. The top of the transmission gear 33 is fixedly connected with a connecting shaft 32. The top of the connecting shaft 32 is fixedly connected with the inner wall of the fixed frame 1. The front end of the first tooth plate 31 is rotatably connected with a first rotating rod 30, and the rear end of the second tooth plate 34 is rotatably connected with a second rotating rod 36. The bottoms of the first rotating rod 30 and the second rotating rod 36 are rotatably connected with a pressure plate 13, and the rear end of the second tooth plate 34 is fixedly connected with a docking rod 35 for docking with the lever 20;

[0032] When the above scheme is put into practical use, when crushing the cassava by-products, the air-dried cassava by-products are placed on the first conveyor belt 8. It should be noted that when placing the cassava by-products, the tail end of the rhizome is placed on the first conveyor belt 8, that is, the end of the rhizome with branches faces forward. The purpose of this is that during transportation, the extrusion block 16 will contact and restrict the tail end before the tail end, and then separate the branches at the front end, and transport it to the inside of the fixed frame 1 through the first conveyor belt 8, and drive the transmission crawler 14 to rotate through the driving device, and the rotation speed of the transmission crawler 14 is consistent with the transmission speed of the first conveyor belt 8. When the cassava by-products slide to the bottom of the transmission crawler belt 14, the extrusion block 16 on the transmission crawler belt 14 will contact the cassava by-products as the transmission crawler belt 14 rotates, and the contact pressure gradually increases as the transmission crawler belt 14 rotates, so that the sliding seat 17 retracts the compression fixing spring onto the fixed plate 18. Since the rotation speeds of the transmission crawler belt 14 and the first conveyor belt 8 are the same, the rhizome is fixed by the extrusion block 16, so that the position of the rhizome can be limited and the rhizome can be transported;

[0033] When the driving track 14 rotates through the rotating roller 15, the driving belt 21 drives the driving wheel 19 to rotate together, so that the lever 20 will contact the docking rod 35. As the lever 20 rotates, the docking rod 35 is pushed forward to slide. The docking rod 35 drives the second tooth plate 34 to slide together. The second tooth plate 34 drives the transmission gear 33 to rotate. The transmission gear 33 drives the first tooth plate 31 to slide at the same time, and the sliding directions of the first tooth plate 31 and the second tooth plate 34 are opposite. The first tooth plate 31 and the second tooth plate 34 respectively drive the first rotating rod 30 and the second rotating rod 36 to rotate, so that the bottom pressure plate 13 slides downward. When the lever 20 rotates to a position where it is out of contact with the docking rod 35, the connecting shaft 32 is sleeved on the connecting shaft There is a first torsion spring whose bottom is fixedly connected to the transmission gear 33. As the transmission gear 33 rotates, the first torsion spring gradually increases the pressure. After being disengaged from the squeezing of the lever 20, the first torsion spring drives the transmission gear 33 to reverse, so that the first tooth plate 31 and the second tooth plate 34 are reset, thereby driving the pressure plate 13 to reset upward, thereby forming an up and down cycle of the pressure plate 13 until the lever 20 rotates again to a position in contact with the docking rod 35. The purpose of this is to press the pressure plate 13 vertically downward to break the branches on the cassava by-products that have been fixed by the squeezing block 16 at one end. Since the rhizome is already in a dried state at this time, it can be broken by ordinary downward pressure, and the cassava by-products are initially broken.

[0034] As a further solution of the present invention, a second conveyor belt 9 is fixedly connected to the bottom of the fixed frame 1, and the side wall of the second conveyor belt 9 can fit the side wall of the fixed frame 1. A secondary crushing wheel 11 corresponding to the position of the second conveyor belt 9 is rotatably connected to the crushing chamber 2.

[0035] When the above scheme is put into actual use, the branches broken by the pressing plate 13 may also break off, and the broken branches will fall onto the second conveyor belt 9, and then be transported by the second conveyor belt 9 through the secondary crushing wheel 11 for crushing, ensuring that the roots on the second conveyor belt 9 and the first conveyor belt 8 can be effectively crushed.

[0036] As a further solution of the present invention, a connecting disc 27 is fixedly connected to the transmission wheel 19, a convex shaft 26 is fixedly connected to the outer wall of one end of the connecting disc 27, a connecting frame 28 is slidably sleeved on the outside of the convex shaft 26, a connecting plate 22 is fixedly connected to the side wall of the connecting frame 28, a rack plate 23 is fixedly connected to the front end of the connecting plate 22, a telescopic rod 29 is slidably connected to the top of the rack plate 23, and the top of the telescopic rod 29 is fixedly connected to the inner wall of the fixed frame 1, a rotating wheel 25 is rotatably sleeved on the first conveyor belt 8, gear teeth for meshing with the rack plate 23 are provided on the outer wall of the rotating wheel 25, and a sawtooth 24 is fixed to the front end of the rotating wheel 25;

[0037] When the above scheme is put into practical use, when the transmission crawler 14 rotates to pre-crush the cassava by-products, the transmission wheel 19 rotates and drives the connecting plate 27 to rotate. The connecting plate 27 drives the connecting frame 28 to slide up and down through the convex shaft 26. The connecting frame 28 drives the rack plate 23 to slide back and forth outside the telescopic rod 29 through the connecting plate 22. When the rack plate 23 slides downward, it drives the rotating wheel 25 to rotate through the engagement with the rotating wheel 25. When the rack plate 23 slides upward, it drives the rotating wheel 25 to rotate in the opposite direction. When the rotating wheel 25 rotates back and forth in this way, the saw teeth 24 at its front end will saw off the excess branches on the rhizome passing through the rotating wheel 25. In cooperation with the pressing and breaking process of the pressing plate 13, the pressing plate 13 mainly cuts off the branches on the vertical section, and the saw teeth 24 can saw off the branches on the remaining cross sections. The pressing plate 13 and the rotating wheel 25 can cooperate to effectively clean up the excess branches on the cassava by-products.

[0038] As a further solution of the present invention, a stirrer 5 is fixedly connected to the top of the stewing furnace 3, a stirring paddle is arranged inside the stewing furnace 3, an output shaft of the stirrer 5 passes through the stewing furnace 3 and is fixedly connected to the stirring paddle, an exhaust hole is arranged on the stewing furnace 3, an air purification component is arranged on one side of the stewing furnace 3, and a heat insulation layer is sleeved on the outer wall of the stewing furnace 3;

[0039] When the above scheme is put into practical use, after adding cassava by-products and soil into the stewing furnace 3, the stirring paddle is driven by the stirrer 5 to rotate, and the soil and cassava by-products are fully mixed. During the stewing process, the exhaust hole can be controlled to open and close to control the exhaust and air intake. The air purification component can treat the smoke generated during the stewing process harmlessly and then discharge it. The heat insulation layer on the outer wall of the stewing furnace 3 can effectively isolate the temperature, so that the external temperature of the stewing furnace 3 is much lower than the internal temperature.

[0040] As a further solution of the present invention, the material clamping swing assembly includes a bottom plate 41, which is fixedly arranged on the inner wall of the fixed frame 1, and the rear end of the rotating wheel 25 is slidably connected to a support seat 39, and the rear end of the support seat 39 is fixedly connected to an alignment shaft 42, and the rear end of the alignment shaft 42 slides through the bottom plate 41 and is arranged behind the bottom plate 41, and a reset spring 40 for its reset is sleeved on the alignment shaft 42, and a connecting belt 38 is fixedly connected to the front end of the support seat 39, and a docking sleeve 37 is fixedly connected to the front end of the connecting belt 38, and the docking sleeve 37 is slidably connected to the inner wall of the fixed frame 1, and a threaded rod 44 is rotatably connected to the rear side of the pressing plate 13, and one end of the threaded rod 44 passes through the pressing plate 13 and is slidably connected to the inner wall of the fixed frame 1, and a limiting frame 43 is arranged at the top of the pressing plate 13, and the rear end of the limiting frame 43 is fixedly connected to the threaded rod 44, and a threaded sleeve 45 is spirally connected to the threaded rod 44, and the threaded sleeve 45 is slidably connected to the pressing plate 13, and a second torsion spring for its reset is arranged inside the pressing plate 13;

[0041] When the above scheme is put into practical use, when the cassava by-products are transported on the first conveyor belt 8, if the tail end of the rhizome is clamped and fixed by the squeezing block 16 and the first conveyor belt 8, and the pressing plate 13 is at the bottom at this time, since the rhizome on the first conveyor belt 8 is in a sliding state in the horizontal direction relative to the pressing plate 13, the larger branches on the clamped rhizome may slide to the top of the pressing plate 13 and limit the pressing plate 13 from sliding upward. At this time, when the pressing plate 13 is reset upward, due to the limitation of the branches, the pressing plate 13 will rotate around the threaded rod 44, thereby driving the threaded sleeve 45 to rotate together. The threaded sleeve 45 rotates and slides one end position on the threaded rod 44. After the threaded rod 44 slides to the bottom with the pressure plate 13, the threaded rod 44 is located inside the docking sleeve 37. The opening at the top of the docking sleeve 37 does not restrict the sliding of the threaded rod 44. When the extended threaded sleeve 45 slides upward with the threaded rod 44, it will be restricted inside the docking sleeve 37 due to the insufficient size of the top opening of the docking sleeve 37. As the threaded sleeve 45 rises with the pressure plate 13, it drives the docking sleeve 37 to slide upward together. The docking sleeve 37 pulls the support seat 39 to slide through the connecting belt 38, and the support seat 39 is fixed to the inner part of the frame 1. The wall is horizontally slidably connected, so that the support seat 39 is pulled by the connecting belt 38 to slide horizontally inside the fixed frame 1, so that the reset spring 40 is stretched, and when the pressing plate 13 is gradually rotated and raised by the branch restriction, the pressing plate 13 slides upward to a position separated from the branch, and the pressing plate 13 is reset under the elastic force of the second torsion spring inside the pressing plate 13. At this time, the pressing plate 13 drives the threaded sleeve 45 to reverse, so that the threaded sleeve 45 slides back to the initial position along the threaded rod 44, that is, the threaded sleeve 45 will be separated from the inside of the docking sleeve 37 again. After losing the support of the threaded sleeve 45, the reset elastic force of the reset spring 40 The docking sleeve 37 is reset under the action of its own gravity, and the reset spring 40 pushes the support seat 39 and the rotating wheel 25 to release the elastic force to perform reciprocating motion, so that the saw teeth 24 at the front end of the rotating wheel 25 can synchronously reciprocate. The advantage of this is that when the rotating wheel 25 drives the saw teeth 24 to rotate and saw off branches, when encountering thicker branches and driving the pressure plate 13 to rotate, after the pressure plate 13 is reset, when the saw teeth 24 contact the branches, they can improve the sawing effect on the branches through the impact of the horizontal reciprocating sliding of the saw teeth 24 while rotating and sawing, and the effect is better when sawing thicker branches.

[0042] As a further solution of the present invention, a bucket 7 is rotatably connected to the top of the stewing furnace 3, and a second feed port 6 for docking with the bucket 7 is opened on the top of the stewing furnace 3, and the tops of the first feed port 4 and the second feed port 6 are respectively buckled with sealing covers;

[0043] When the above scheme is put into actual use, when adding soil to the stewing furnace 3, the bucket 7 can be controlled to shovel the soil through the second feed port 6 and send the soil into the stewing furnace 3. Because a large amount of soil is required for the preparation of carbon soil, the bucket 7 can quickly add soil to the stewing furnace 3.

[0044] A method for preparing cassava carbon soil, using a cassava carbon soil preparation device, the method comprises the following steps:

[0045] Step 1: air-dry the discarded cassava by-products and put them into the fixed frame 1, and then preliminarily crush the cassava by-products through a pre-crushing and transportation mechanism in the fixed frame 1 to obtain crushed material 1;

[0046] Step 2: The obtained crushed material 1 is sent into the crushing chamber 2, and crushed again by the primary crushing wheel 10 to obtain the crushed material 2; and then transported to the inside of the stewing furnace 3 by the third conveyor belt 12;

[0047] Step 3: Add an appropriate amount of soil into the stewing furnace 3 to match the crushed material 2 entering the stewing furnace 3 in step 2, and stew in the stewing furnace 3;

[0048] Step 4: After the stewing is completed, the product is taken out from the discharge port at the bottom of the stewing furnace 3, and cassava carbon soil can be obtained after cooling.

[0049] Working principle: when crushing cassava by-products, the air-dried cassava by-products are placed on the first conveyor belt 8. It should be noted that when placing the cassava by-products, the tail end of the rhizome is placed on the first conveyor belt 8, that is, the end of the rhizome with branches faces forward. The purpose of this is that during transportation, the extrusion block 16 will contact and restrict the tail end before the tail end, and then separate the branches at the front end, and transport it to the inside of the fixed frame 1 through the first conveyor belt 8, and drive the transmission crawler 14 to rotate through the driving device, and the rotation speed of the transmission crawler 14 is consistent with the transmission speed of the first conveyor belt 8. When the cassava by-products slide to the bottom of the transmission crawler 14, the extrusion block 16 on the transmission crawler 14 will rotate with the transmission crawler 14 The driving crawler 14 is in contact with the cassava by-products, and the contact pressure gradually increases with the rotation of the driving crawler 14, so that the sliding seat 17 retracts to the fixed plate 18 and compresses the fixed spring. Since the driving crawler 14 and the first conveyor belt 8 rotate at the same speed, the rhizomes are fixed by the extrusion block 16, so that the position of the rhizomes can be limited and the rhizomes can be transported. While the driving crawler 14 rotates through the rotating roller 15, the driving belt 21 drives the driving wheel 19 to rotate together, so that the lever 20 will contact the docking rod 35. As the lever 20 rotates, the docking rod 35 is pushed forward to slide, and the docking rod 35 drives the second tooth plate 34 to slide together, and the second tooth plate 34 drives the transmission gear 33 to rotate, and the transmission gear 33 drives the first tooth plate 31 at the same time. The first tooth plate 31 and the second tooth plate 34 slide in opposite directions. The first tooth plate 31 and the second tooth plate 34 respectively drive the first rotating rod 30 and the second rotating rod 36 to rotate, so that the bottom pressure plate 13 slides downward. When the lever 20 rotates to a position where it is out of contact with the docking rod 35, a first torsion spring fixedly connected to the bottom of the transmission gear 33 is sleeved on the connecting shaft 32. As the transmission gear 33 rotates, the first torsion spring gradually increases the pressure. After being out of the squeezing of the lever 20, the first torsion spring drives the transmission gear 33 to reverse, so that the first tooth plate 31 and the second tooth plate 34 are reset, thereby driving the pressure plate 13 to reset upward, thereby forming an up and down cycle of the pressure plate 13, until the lever 20 rotates to At the position in contact with the docking rod 35, when the wheel 25 rotates back and forth in this way, the saw teeth 24 at the front end thereof will saw off the excess branches on the rhizome passing through the wheel 25, and cooperate with the pressing and breaking processing of the pressing plate 13. The pressing plate 13 mainly presses and cuts the branches on the vertical section, while the saw teeth 24 can saw off the branches on the remaining cross section. The crushed product enters the crushing chamber 2 again, is crushed again by the first-level crushing wheel 10, and is transported to the inside of the stewing furnace 3 through the third conveyor belt 12. An appropriate amount of soil is added to the stewing furnace 3 to cooperate with the cassava by-products entering the stewing furnace 3, and stewing is carried out inside the stewing furnace 3.
