[0002] Crop straw is a large byproduct of agricultural production, mainly including the stalks remaining after harvesting crops such as wheat, corn, and rice. In recent years, with increased awareness of environmental protection and technological advancements, straw carbonization has gradually gained attention as a means of renewable energy conversion. Converting biomass into biochar through pyrolysis not only reduces greenhouse gas emissions but also produces high-value-added products such as activated carbon and carbon-based fertilizers.

[0003] However, existing stationary carbonization equipment requires the collection of straw scattered in various locations, followed by transportation to a specific site for centralized processing. This process is not only time-consuming and labor-intensive, but also increases transportation costs and energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a mobile straw carbonization collection device that can process straw directly in the field without the need for pre-collection and long-distance transportation of straw, thus greatly simplifying the processing procedure.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A mobile straw carbonization and collection device includes a mobile vehicle body, a carbonization box mounted on the vehicle body, a feed inlet at the top of the carbonization box, a crushing box mounted on the front end of the vehicle body, a crushing mechanism inside the crushing box, a chain conveyor between the crushing box and the feed inlet of the carbonization box, and a shell fixedly connected to the front end of the crushing box, with a straw picking mechanism installed inside the shell.

[0007] Furthermore, the straw picking mechanism includes a picking cylinder rotatably connected to the bottom of the front end of the inner side of the housing, the picking cylinder being equipped with multiple spring teeth, and a first drive motor for driving the picking cylinder to rotate being installed on the outer side of the housing.

[0008] Furthermore, a threaded feed cylinder is rotatably provided at the rear end of the inner side of the housing, and a second drive motor for driving the threaded feed cylinder to rotate is installed on the outer side of the housing.

[0009] Furthermore, a traction frame is provided on the housing.

[0010] Furthermore, the crushing mechanism includes a fixed shaft fixedly connected inside the crushing chamber, a fixed blade fixedly connected to the fixed shaft, a rotating shaft rotatably arranged inside the crushing chamber, a plurality of movable blades mounted on the rotating shaft, the movable blades being arranged close to the fixed blades, and a third drive motor for driving the rotating shaft to rotate is installed on the outside of the crushing chamber.

[0011] Furthermore, the feed end of the chain conveyor extends into the crushing box, and a conveying shaft is rotatably arranged inside the crushing box near the chain conveyor. The two ends of the conveying shaft are equipped with spiral blades with opposite rotation directions, and a material-pushing plate is installed in the middle of the conveying shaft. The material-pushing plate is positioned directly opposite the chain conveyor, and a rotary motor that drives the conveying shaft to rotate is installed on the outside of the crushing box.

[0012] Furthermore, two mounting plates are symmetrically fixedly connected to the rear sides of the mobile vehicle body, and a rotating shaft is rotatably connected between the mounting plates. Multiple annular plates are fixedly sleeved on the rotating shaft, and multiple soil turning and stubble purging blades are installed on both sides of the annular plates. A fourth drive motor for driving the rotating shaft to rotate is installed on the mounting plate shown in the figure. The carbonization box has a discharge port directly opposite the soil turning and stubble purging blades.

[0013] Furthermore, a scraper is fixedly connected between the rear ends of the two mounting plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] like Figures 1 to 3 As shown, a mobile straw carbonization and collection device includes a mobile vehicle body 1, a carbonization box 2 mounted on the mobile vehicle body 1, a feed inlet 201 at the top of the carbonization box 2, a crushing box 3 mounted on the front end of the mobile vehicle body 1, a crushing mechanism inside the crushing box 3, a chain conveyor 4 between the crushing box 3 and the feed inlet 201 of the carbonization box 2, and a housing 5 fixedly connected to the front end of the crushing box 3, with a straw picking mechanism installed inside the housing 5.

[0021] The straw picking mechanism includes a picking cylinder 6 rotatably connected to the bottom of the front end of the inner side of the housing 5. The picking cylinder 6 is equipped with multiple spring teeth 7, and a first drive motor 8 is installed on the outer side of the housing 5 to drive the picking cylinder 6 to rotate.

[0022] A threaded feed cylinder 9 is rotatably provided on the inner rear end of the housing 5, and a second drive motor 10 is installed on the outer side of the housing 5 to drive the threaded feed cylinder 9 to rotate.

[0023] A traction frame 11 is provided on the housing 5.

[0024] The crushing mechanism includes a fixed shaft 13 fixedly connected inside the crushing box 3, a fixed blade 14 fixedly connected to the fixed shaft 13, a rotating shaft 15 rotatably arranged inside the crushing box 3, a plurality of moving blades 16 mounted on the rotating shaft 15, the moving blades 16 being arranged close to the fixed blades 14, and a third drive motor 17 for driving the rotating shaft 15 to rotate is installed on the outside of the crushing box 3.

[0025] The feed end of the chain conveyor 4 extends into the crushing box 3. A conveying shaft 18 is rotatably arranged in the crushing box 3 near the chain conveyor 4. Spiral blades 19 with opposite rotation directions are installed at both ends of the conveying shaft 18. A material-pushing plate 20 is installed in the middle of the conveying shaft 18. The material-pushing plate 20 is positioned directly opposite the chain conveyor 4. A rotary motor 26 that drives the conveying shaft 18 to rotate is installed on the outside of the crushing box 3.

[0026] Two mounting plates 21 are symmetrically fixedly connected to the rear sides of the mobile vehicle body 1. A rotating shaft 22 is rotatably connected between the mounting plates 21. Multiple annular plates 23 are fixedly sleeved on the rotating shaft 22. Multiple soil turning and stubble purging blades 24 are installed on both sides of the annular plates 23. A fourth drive motor 25 is installed on the mounting plate 21 to drive the rotating shaft 22 to rotate. A discharge port 202 is located on the carbonization box 2, directly opposite the soil turning and stubble purging blades 24.

[0027] A scraper 12 is fixedly connected between the rear ends of the two mounting plates 21.

[0028] Working principle:

[0029] The mobile vehicle body 1 is towed by a tractor or other vehicle via a towing frame 11, enabling flexible movement of the device. During operation, the first drive motor 8 drives the pickup cylinder 6 to rotate, allowing the spring teeth 7 to effectively roll the straw on the ground into the housing 5. After the picked-up straw enters the housing 5, the second drive motor 10 drives the threaded conveyor cylinder 9 to further transport the straw into the crushing box 3. The third drive motor 17 drives the rotating shaft 15 to rotate, and the moving blade 16 cooperates with the fixed blade 14 to cut the straw into small pieces for subsequent carbonization. The rotating motor 6 drives the conveying shaft 18 to rotate, which in turn drives the spiral blade 19 and the feeding plate 20 to rotate. The cut straw is conveyed to the chain conveyor 4, and then conveyed to the feed inlet 201 of the carbonization box 2. The carbonization box 2 undergoes a pyrolysis reaction to convert biomass into biochar. The carbonized product can be discharged through the discharge outlet 202 and used as carbon-based fertilizer. The fourth drive motor 25 drives the rotating shaft 22 to rotate. The soil turning and stubble-removing blades 24 can turn over the soil and remove the crop stubble left in the field after harvesting. The soil raised is used to cover the carbon-based fertilizer, burying the fertilizer in the soil and preventing the carbon-based fertilizer from continuing to burn due to high temperature after carbonization. The land is leveled by the scraper 12.

[0030] This utility model integrates the functions of picking up, crushing, conveying and carbonizing into one, realizing one-stop processing from straw collection to carbonized finished product, which greatly improves work efficiency, reduces transportation links and time, reduces operating costs, and also reduces straw loss during transportation.
