Description

Technical Field

[0001] This invention relates to the field of agricultural waste treatment devices, and more particularly to a device that can carbonize agricultural waste on-site and return it to the field. Background Technology

[0002] Carbonization, broadly speaking, refers to a reaction process in which biomass or organic matter is decomposed by heating under anaerobic or ventilated conditions. In current crop production, crops such as corn, after being harvested manually or by combine harvesters, leave behind a large amount of straw, dead branches, and fallen leaves on the field surface. This is difficult to clean up, and the costs of collection, storage, and transportation are high. In order not to affect the following year's planting, growers often burn these wastes on-site, which not only causes serious environmental pollution and waste of resources, but also poses a great fire hazard. Carbonizing these crop wastes left on the field surface on-site and burying them in the farmland soil can effectively solve the above problems. It can not only achieve low-carbon, high-efficiency, and circular utilization of agricultural waste resources, taking from the field and using it in the field, effectively increasing the input of external substances into the soil and maintaining the soil's "input-output" balance, but also improve soil structure, increase soil carbon sequestration, improve soil fertility, promote crop growth, and increase yield and quality, turning waste into treasure, achieving multiple benefits in one fell swoop, greatly reducing the cost of agricultural waste treatment and labor input, and jointly solving problems such as the burning of straw and other wastes, as well as the efficient utilization of residual agricultural waste in the field.

[0003] In the prior art, such as the high-efficiency straw carbonization device described in Chinese Patent Application No. 201310202163.3, a crusher (1), an auger drying and conveying mechanism (2), a carbonization furnace (3), a coking and dust removal device (4), and a gas collection device (5) are used. The straw is first crushed by the crusher (1) and then fed into the auger drying and conveying mechanism (2). During the conveying process, the crushed straw is quickly dried and then sent to the carbonization furnace (3) for carbonization to improve carbonization efficiency. The dust and gas generated during the carbonization process are collected and treated by the coking and dust removal device (4) and the gas collection device (5) to achieve zero pollution emissions. This invention overcomes the shortcomings of traditional carbonization furnaces, which have long and inefficient time cycles for raw material dehydration and carbonization. It has the advantages of reasonable structure, energy saving and environmental protection, reduced labor, and improved straw carbonization production efficiency. It can achieve multiple uses and is easy to promote and use.

[0004] While this device can carbonize agricultural waste, it collects crop straw from the field before carbonizing it; it cannot directly collect, carbonize, and return the remaining agricultural waste to the field. To better treat agricultural waste remaining on the field surface, this invention designs a device that can carbonize and return agricultural waste to the field in situ. This device can directly collect and carbonize agricultural waste from the farmland, and then bury the carbonized material in the farmland soil. Summary of the Invention

[0042] The other structures in this embodiment are the same as in Embodiment 1.

[0043] Example 3: Based on Example 2, a technical means of burying carbonized materials was added.

[0044] Two first pump bodies 6 are fixedly installed on the first mounting plate 3. Each of the two first pump bodies 6 is connected to a third pipe 8, which communicates with the bottom of the carbonization box 4. A fireproof backflow mechanism is also provided between the third pipe 8 and the carbonization box 4. Each of the two first pump bodies 6 is connected to a second pipe 7, and the side of each second pipe 7 away from the first pump body 6 communicates with the working box 12. Two partition plates 43 are fixedly connected to the cavity inside the working box 12, dividing the interior of the working box 12 into three cavities. The middle cavity is used to hold the carbonized material. A second sliding groove 46 is opened at the bottom of the middle cavity, and a baffle 47 is slidably connected within the second sliding groove 46. The height of the baffle 47 is greater than the shell thickness of the working box 12. A blocking block 45 is fixedly connected to the bottom of the baffle 47 to block the carbonized material. The bottom of the blocking block 45 is connected to the second bearing seat plate 25. Multiple evenly distributed push plates 31 are fixedly connected to the bottom of the second bearing seat plate 25, and the bottom of each push plate 31 is fixedly connected to a pointed tip 40. The third rotating column 32 and the fourth rotating column 36 rotate respectively within the cavities on both sides. The outer walls of both the third rotating column 32 and the fourth rotating column 36 are fixedly connected to third gears 42.

A fifth rotating column 38 is rotatably connected to the outer wall of the work box 12. A second gear 39 is fixedly connected to the outer wall of the fifth rotating column 38. The fourth rotating column 36 is fixedly connected to a first gear 37 on one side outside the work box 12, and the first gear 37 and the second gear 39 mesh with each other. An L-shaped mounting plate 35 is fixedly connected to the outer wall of the work box 12. The fifth rotating column 38 is rotatably connected to the L-shaped mounting plate 35. A second motor 34 is fixedly connected to the L-shaped mounting plate 35, and the power output end of the second motor 34 is connected to the fifth rotating column 38. A belt 33 is fitted between the fifth rotating column 38 and the third rotating column 32.

[0045] The other structures in this embodiment are the same as in Embodiment 2.

[0046] In this embodiment, the device is first moved to the farmland via the walking track 2. Personnel can sit in the vehicle body 1 and control the walking track 2 using a steering wheel or other drive components, or they can control the walking track 2 via an external Bluetooth control device. Upon reaching the preset position, the power to the first motor 48 and the inclined conveyor belt 13 is activated, driving the threaded rod 18 to rotate back and forth. At this time, the sliding plate 19, under the action of the thread and the limiting action, moves to the right. The sliding plate 19 drives the two first hinge rods 10 to move. Under the limiting action of the first rotating column 21, the two second hinge rods 11 and the work box 12 pull inwards, collecting agricultural waste from the field onto the inclined guide plate 14 via the push plate 31 at its bottom and the tip 40, and pushing it onto the inclined conveyor belt 13. Simultaneously with the movement of the second hinge rods 11 and the work box 12, the first rotating column 21 rotates. The first rotating column 21 drives the spline shaft 23, the spline bushing 24, and the first bevel gear 26 to rotate. The second bearing seat plate 25 is rotatably connected to the outer wall of the splined bushing 24. Since the second bearing seat plate 25 and the second hinge rod 11 remain horizontal, when the second hinge rod 11 and the working box 12 move, the auger bulldozer plate 30 also rotates and moves with the second hinge rod 11 and the working box 12, thereby crushing the sides of long crops or branches in real time with the push plate 31, making it easier for the push plate 31 to convey the crop waste to the inclined conveyor belt 13. The crop waste conveyed to the top of the inclined conveyor belt 13 falls into the crushing box 16 for crushing. Then, when it is observed that the crushing box 16 has crushed a certain amount of material, the second pump body 9 is activated to convey the crushed material from the crushing box 16 to the carbonization box 4. The carbonization box 4 carbonizes the crushed material. Thus, the crop waste is collected, crushed, and carbonized in a fully automated manner.

[0047] After the agricultural waste in the surrounding area has been collected and crushed, the power to the inclined conveyor belt 13 and the first motor 48 is turned off. After the carbonization operation is completed, the two first pumps 6 are started to transfer the carbonized material in the carbonization box 4 to the work box 12. At this time, the power to the second motor 34 is started, causing the shielding block 45 and the second bearing seat plate 25 to move downwards, so that the tip 40 is pressed into the soil of the field. At this time, the auger bulldozer plate 30 is also partially pressed into the soil. Then the opening of the second chute 46 is opened. The carbonized material moves to the top of the baffle 47 and the shielding block 45. At the same time, the power to the first motor 48 is started, and the stroke of the first motor 48 driving the threaded rod 18 is reduced, so that the pusher plate 31 and the tip 40 do not touch the inclined guide plate 14. At this time, the initial speed of the first motor 48 is relatively slow, gradually turning over the soil. After repeating this several times, the carbonized material falls into the field due to inertia. Then, the speed of the first motor 48 is increased when rotating forward, allowing the auger-type bulldozer blade 30 to push the soil it contacts into the area turned over by the pusher plate 31 for burying. The auger-type bulldozer blade 30 moves in tandem with the pusher plate 31, burying the carbonized material in multiple areas of turned soil. Even when the first motor 48 rotates in reverse, the speed remains slow, preventing soil from being thrown backward. This completes the burial of carbonized agricultural waste. Furthermore, the auger-type bulldozer blade 30 has drainage channels, facilitating rainwater flow and preventing the buried carbonized material from easily washing away, thus ensuring the safety of the burial.

[0048] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
