Description

Technical Field

[0001] The present invention relates to the technical field of carbon sequestration devices, and particularly relates to a carbon sequestration device that can effectively reduce soil carbon emissions. Background Art

[0002] The core of soil carbon sequestration is to reduce the release of carbon dioxide into the atmosphere by increasing the long-term storage of organic carbon (such as humus) or inorganic carbon in the soil. Common methods include no-till or reduced tillage: reducing soil turning, lowering the decomposition rate of organic matter, and retaining soil carbon. Cover crops: planting legumes (such as clover) or green manure crops to increase biomass input and reduce soil exposure at the same time. Straw returning to the field: directly returning crop residues (such as corn stalks, wheat straw) to the soil to increase the source of organic matter.

[0003] According to the utility model patent of a carbon sequestration device for effectively reducing soil carbon emissions with the publication number CN220087878U, it includes a frame. At the top of the frame, there is a box body. At the center of the inner part of the box body, there is a partition platform which divides the two sides of the inner cavity of the box body into a first cavity and a second cavity. At both sides of the bottom end of the box body, there are discharge ports, and valve components are arranged inside the discharge ports. In this utility model, when the ground-breaking component operates, it intermittently pushes the push block. The push block drives the valve plate away from the discharge port through a connecting rod. At this time, the activated carbon inside the first cavity is discharged through the discharge port and falls in front of the ground-breaking component. When the ground-breaking component turns the soil, the activated carbon is mixed into the soil. The water inside the second cavity is discharged through the discharge port and infiltrates into the soil mixed with the activated carbon. This carbon sequestration device mixes activated carbon into the soil and waters the soil while turning the soil. It only requires one person to operate, not only with high efficiency but also with low usage cost.

[0004] Although the above technical solution can achieve the effect of carbon sequestration by mixing activated carbon into the soil, the method of using the ground-breaking component to make the push block slide for discharging has certain limitations. Firstly, because their movement modes are different, it is very easy for the ground-breaking component not only to fail to push the push block to slide but also to affect its normal operation. Secondly, only using the ground-breaking component to mix the activated carbon with the soil will not only affect the uniformity of the mixing but also cause a large amount of activated carbon to be exposed on the soil surface, making it difficult to achieve the effect of carbon sequestration. Summary of the Invention

[0005] The purpose of the present invention is to provide a carbon sequestration device that can effectively reduce soil carbon emissions, which can mix crop residues with the soil more evenly and reduce the area of crop residues exposed on the soil surface after mixing, so as to achieve the effect of carbon sequestration of the soil.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions:

[0007] A carbon sequestration device that effectively reduces soil carbon emissions, comprising a walking vehicle with adjustable height, and a storage box installed at the upper end of the walking vehicle and having openings at both the upper and lower ends. Between the left and right sides at the front end of the inner wall of the walking vehicle, a soil loosening component is rotatably connected in cooperation. Inside the walking vehicle, a conveying component is arranged obliquely upward from front to back behind the soil loosening component. Inside the walking vehicle, a material guiding plate is arranged obliquely downward from front to back below the upper end of the conveying component. Inside the support frame, a material distributing component extending to the lower end of the storage box is rotatably connected in cooperation above the material guiding plate. A number of notches for cooperating with the material distributing component are formed upward at the lower end of the outer wall of the storage box. Below the lower end of the rear end of the outer wall of the storage box, a scraping component for cooperating with the material distributing component is arranged.

[0008] On the left and right sides at the rear end of the outer wall of the walking vehicle, sliding rails are oppositely arranged. At the rear end of the bottom of the walking vehicle, a pressing component slidably connected in cooperation with the sliding rails is arranged. At the front end of the upper end of the walking vehicle, a driving motor and a storage battery are installed. On the outer wall of the power output shaft of the driving motor, a first belt pulley is arranged. At one end of the outer wall of the soil loosening component, a double-groove belt pulley is arranged. Between one groove of the first belt pulley and the double-groove belt pulley, transmission is carried out through a first belt. At one end of the material distributing component, a second belt pulley is arranged. Between the other groove of the double-groove belt pulley and the second belt pulley, transmission is carried out through a second belt. On the left and right sides at the upper end of the outer wall of the conveying component, first gears are arranged. On the left and right sides of the outer wall of the material distributing component, second gears meshing with the corresponding first gears are installed.

[0009] By adopting the above technical solution, during use, first put the crushed matter of crop residues into the storage box, then use the electric energy provided by the storage battery to move the walking vehicle to the position where carbon sequestration is required. Then let the driving motor work. The driving motor drives the double-groove belt pulley and the soil loosening component to rotate through the first belt pulley and the first belt. At the same time, the double-groove belt pulley drives the second belt pulley and the material distributing component to rotate through the second belt. And it also drives the conveying component to rotate through the meshing of the first gear and the second gear. Through the cooperation of the first gear and the second gear, the rotation directions of the material distributing component and the conveying component are opposite. Adjust the height of the walking vehicle to make the soil loosening component and the pressing component contact the soil surface and penetrate into the soil to a certain depth. Then let the walking vehicle move forward. During this process, the soil loosening component loosens and scatters the soil, and then the conveying component picks up the soil and conveys it backward to the material guiding plate. At the same time, the material distributing component also pulls out the crop residues from the storage box and, under the scraping and blocking effects of the scraping component, follows the soil and falls on the rear soil along the material guiding plate. Then the pressing component presses the crop residues into the soil, which not only plays a role in deep burial but also improves the firmness of the crop residues in the soil.

[0010] A further setting of the present invention is that the walking vehicle includes a support frame, a plurality of first electric push rods mounted at the lower end of the support frame and distributed in an array, hub motors respectively mounted at the lower ends of the first electric push rods, a handrail frame cooperatively arranged at the rear of the upper end of the support frame, and a control panel arranged above the inner wall of the handrail frame.

[0011] A further setting of the present invention is that the soil loosening component includes a fixed shaft, a plurality of soil loosening blades arranged along the outer wall length direction of the fixed shaft and distributed at equal intervals, and each adjacent two soil loosening blades are arranged in a staggered manner.

[0012] By adopting the above technical solution, the soil loosening blades with a staggered angle can break the soil surface more evenly, improving the soil loosening effect and the looseness of the loosened soil at the same time.

[0013] A further setting of the present invention is that the conveying component includes a roller, a conveyor belt cooperatively arranged on the outer walls of the two rollers, a plurality of retaining pieces distributed at equal intervals on the upper and lower ends of the outer wall of the conveyor belt, and baffles respectively arranged on the left and right sides of the outer wall of the conveyor belt.

[0014] A further setting of the present invention is that the material pushing component includes a rotating shaft, a plurality of material pushing rods arranged on the outer wall of the rotating shaft and distributed at equal intervals, and each adjacent two material pushing rods are arranged in a staggered manner.

[0015] A further setting of the present invention is that the material scraping component includes a scraping plate, a plurality of connecting rods arranged at the rear end of the scraping plate, and a plurality of cleaning grooves distributed at equal intervals and corresponding to the material pushing rods one by one, which are opened at the front end of the upper end of the outer wall of the scraping plate.

[0016] By adopting the above technical solution, it is possible to prevent crop residues from remaining on the pushing rods during the operation of the material pushing component, avoiding affecting its normal operation.

[0017] A further setting of the present invention is that the material pressing component includes a second electric push rod, a fixed rod horizontally arranged at the lower end of the second electric push rod, a plurality of fixed brackets distributed at equal intervals and arranged in a U shape at the lower end of the fixed rod, and pressing discs respectively rotatably connected between the left and right sides of the inner wall of the fixed brackets.

[0018] A further setting of the present invention is that a U-shaped pressing plate is arranged on the rear end of the outer wall of the fixed rod and slopes downward from front to back.

[0019] By adopting the above technical solution, it is possible to level the soil at the edge and on the plane after the material pressing is completed, and to a certain extent, improve the coverage rate of the soil on the crop residues.

[0020] A further setting of the present invention is that: above the front end of the conveying assembly, a soil shovel is arranged in cooperation and obliquely downward from back to front and extends below the rear end of the soil loosening assembly. The soil shovel is large at the front and small at the rear and is arranged in a U shape.

[0021] In summary, the present invention has the following beneficial effects:

[0022] First, the present invention can mix crop residues with the soil more evenly, and after mixing, it can reduce the area of crop residues exposed on the soil surface, thereby achieving the effect of soil carbon sequestration;

[0023] Second, the present invention can drive multiple components to work through one driving motor to realize operations such as soil loosening, conveying, and material dialing, reducing energy consumption;

[0024] Third, the cooperation of the pressure component and the pressing plate of the present invention can not only press the crop residues into the soil, but also improve the coverage rate of the soil on the crop residues, facilitating soil carbon sequestration. Description of the Drawings

The soil loosening assembly 17 includes a fixed shaft 18 and a plurality of soil loosening blades 19 arranged along the length direction of the outer wall of the fixed shaft 18 and distributed at equal intervals. Each adjacent two soil loosening blades 19 are arranged in a staggered manner.

The conveying component 2 includes a roller 21, a conveyor belt 22 arranged on the outer walls of the two rollers 21, a number of baffles 23 evenly distributed at the upper and lower ends of the outer wall of the conveyor belt 22, and baffles 24 respectively arranged on the left and right sides of the outer wall of the conveyor belt 22 and sleeved on the outer wall of the roller 21. Above the front end of the conveying component 2, a soil shovel 25 is arranged obliquely downward from back to front and extends below the rear end of the soil loosening component 17. The soil shovel 25 is large at the front and small at the rear and is U-shaped. Inside the walking vehicle 1, a U-shaped guide plate 5 is arranged obliquely downward from front to back below the upper end of the conveying component 2. Inside the support frame 11, a feeding component 26 extending to the lower end of the storage bin 16 is rotatably connected above the guide plate 5. The feeding component 26 includes a rotating shaft 27 and a number of feeding rods 28 arranged on the outer wall of the rotating shaft 27 and evenly distributed. Each adjacent two feeding rods 28 are arranged in a staggered manner. A number of notches 33 corresponding to the feeding rods 28 one by one and allowing them to pass through are opened upward at the lower end of the outer wall of the storage bin 16.

[0037] Below the rear end of the outer wall of the storage bin 16, a scraping component 29 used in cooperation with the feeding component 26 is arranged. The scraping component 29 includes a scraping plate 3, a number of connecting rods 31 arranged at the rear end of the scraping plate 3, and a number of cleaning grooves 32 evenly distributed at the upper front end of the outer wall of the scraping plate 3 and corresponding to the feeding rods 28 one by one. On the left and right sides of the rear end of the outer wall of the walking vehicle 1, a slide rail 34 is arranged oppositely. At the rear end of the bottom of the walking vehicle 1, a pressing component 35 slidably connected with the slide rail 34 is arranged. The pressing component 35 includes a second electric push rod 36, a fixing rod 37 horizontally arranged at the lower end of the second electric push rod 36, a number of fixing frames 38 evenly distributed at the lower end of the fixing rod 37 and U-shaped, and a number of pressing plates 39 respectively rotatably connected between the left and right sides below the inner walls of the fixing frames 38. At the rear end of the outer wall of the fixing rod 37, a U-shaped pressing plate 4 is arranged obliquely downward from front to back.

[0038] At the front end of the upper end of the walking vehicle 1, a driving motor 41 and a storage battery 49 are installed. On the outer wall of the power output shaft of the driving motor 41, a first belt pulley 42 is arranged. At one end of the outer wall of the soil loosening component 17, a double-groove belt pulley 43 is arranged. Between the first belt pulley 42 and one groove of the double-groove belt pulley 43, transmission is carried out through a first belt 44. At one end of the feeding component 26, a second belt pulley 45 is arranged. Between the second belt pulley 45 and the other groove of the double-groove belt pulley 43, transmission is carried out through a second belt 46. On the left and right sides of the upper end of the outer wall of the conveying component 2, a first gear 47 is arranged respectively. On the left and right sides of the outer wall of the rotating shaft 27, a second gear 48 meshing with the corresponding first gear 47 is installed. The first electric push rod 12, the hub motor 13, the driving motor 41, the second electric push rod 36 and the storage battery 49 are all electrically connected to the control panel 15.

[0039] Usage method: When in use, first put the crushed materials of crop residues into the storage bin 16, and then the battery 49 provides electrical energy and operates the control panel 15 on the handrail 14 to control the hub motor 13 to work, moving the walking vehicle 1 to the position where carbon sequestration is required. Then, let the drive motor 41 work. The drive motor 41 drives the double-groove pulley 43 and the soil loosening assembly 17 to rotate through the first pulley 42 and the first belt 44. At the same time, the double-groove pulley 43 drives the second pulley 45 and the material feeding assembly 26 to rotate through the second belt 46, and also drives the conveying assembly 2 to rotate through the meshing of the first gear 47 and the second gear 48. Through the cooperation of the first gear 47 and the second gear 48, the rotation directions of the material feeding assembly 26 and the conveying assembly 2 are set in the opposite direction. Then, let the first electric push rod 12 on the support frame 11 shorten a certain length to adjust the height of the walking vehicle 1 so that the soil loosening assembly 17 and the material pressing assembly 35 are in contact with the soil surface and penetrate into the soil to a certain depth.

[0040] Operate the control panel 15 again to make the second electric push rod 36 extend a certain length, let the fixed rod 37 slide down along the slide rail 34, and make the pressing plate 39 in the fixing frame 38 penetrate into the soil again. At this time, the depth of the pressing plate 39 in the soil is greater than the depth of the soil loosening assembly 17 in the soil. Then, let the walking vehicle 1 move forward. During this process, the soil loosening blades 19 on the fixed shaft 18 will break up and loosen the soil. Since the adjacent soil loosening blades 19 are arranged in a staggered manner, the soil can be broken up more evenly, reducing the number of soil blocks. As the walking vehicle 1 continues to move, the broken-up soil will fall onto the conveyor belt 22 of the conveying assembly 2 along the soil shovel 25, and the roller 21 drives the conveyor belt 22 to rotate upward to lift the soil and convey it backward to the guide plate 5. The baffle 23 can increase the amount of soil conveyed, and the baffle 24 can prevent the conveyed soil from falling from its left and right sides.

[0041] At the same time, the material feeding rod 28 on the rotating shaft 27 will also pull out the crop residues from the lower opening of the storage bin 16 and, under the scraping and blocking effects of the scraping assembly 29, follow the soil and fall onto the rear soil along the guide plate 5. When feeding the material, the notch 33 at the lower end of the storage bin 16 facilitates the passage of the material feeding rod 28, thus realizing the feeding of the material. The scraper 3 on the connecting rod 31 can scrape off the crop residues on the material feeding rod 28 through the cleaning groove 32, so that the crop residues can slide down along the guide plate 5 together with the soil. The fallen soil and crop residues are pressed into the soil by the pressing plate 39, which not only plays a role in deep burial but also improves the firmness of the crop residues in the soil. The pressing plate 4 can not only gather the soil at the edge but also level the uneven soil surface, improving the coverage rate of the soil on the crop residues.

[0042] This specific embodiment is only an interpretation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications with creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
