Description

Technical Field

[0001] This invention relates to the field of soil improvement technology, and more particularly to a soil mixing device using bamboo sheath biochar for soil improvement. Background Technology

[0002] Soil improvement refers to the application of scientific theories and knowledge to address soil degradation and enhance soil fertility through technical measures. This creates a favorable growing environment for crops. The methods of soil improvement need to be adjusted according to the specific soil conditions. Using bamboo sheath biochar is one such method. Bamboo sheath biochar is added to the soil, and by turning the soil over, it mixes quickly with the biochar, allowing the soil to absorb the biochar and improve fertility. However, existing equipment has a relatively fixed coverage area. If the soil area exceeds the machine's coverage, operators need to repeatedly spread the biochar, which is time-consuming and inefficient.

[0003] Therefore, in order to address the above problems, a bamboo sheath biochar soil regional mixing device for improving soil is now being developed, which can adjust the machine coverage area according to the size of the soil area. Summary of the Invention

[0004] To overcome the shortcomings of existing devices, which require operators to repeatedly spread the soil when the soil area is larger than the machine's coverage area, resulting in significant time consumption and reduced efficiency, a bamboo sheath biochar soil area mixing device is provided that can adjust the machine's coverage area according to the size of the soil area.

[0005] Technical solution: A soil mixing device for improving soil with bamboo sheath biochar, characterized in that it includes a mounting frame, a first sliding frame, a second sliding frame, a first servo motor, a first mixing roller, a feeding mechanism, and an unfolding mechanism.

The right side of the third mixing roller is connected to the left side of the second sliding frame.

[0008] Furthermore, it is particularly preferred that the device also includes an intermittent mechanism for intermittently spreading bamboo sheath biochar. The intermittent mechanism includes a first fixed plate, a first spring, a first rotating shaft, a second rotating shaft, a first pulley assembly, a gear, a rack, and a cam. Two first fixed plates are bolted to the opposite sides of the first blocking plates, and first fixed plates are bolted to the opposite sides of the second blocking plates. A first spring connects the four first fixed plates on the left to the placement frame, and a first spring connects the two first fixed plates on the right to the expansion frame. A first rotating shaft is rotatably connected to the left side of the placement frame, and a first rotating shaft is rotatably connected to the right side of the expansion frame. A second rotating shaft is rotatably connected to the left side of the placement frame, and a second rotating shaft is rotatably connected to the right side of the expansion frame. A first pulley assembly connects the first and second rotating shafts on the left, and a first pulley assembly also connects the first and second rotating shafts on the right. A cam is connected to each of the first rotating shafts, a gear is connected to each of the second rotating shafts, and a rack is connected to the upper rear of the mounting frame.

[0009] Furthermore, it is particularly preferred that the device also includes a propulsion mechanism for automatically moving the first sliding frame and the second sliding rod frame. The propulsion mechanism includes a second servo motor, a second pulley assembly, and a lead screw. The second servo motor is bolted to the upper front part of the mounting bracket on the left side, and the lead screw is rotatably connected to the right side of the mounting bracket on the left side. The lead screw is threadedly connected to the first sliding frame, and the second pulley assembly is connected between the front end of the lead screw and the output shaft of the second servo motor.

[0010] Furthermore, it is particularly preferred that the mounting bracket also includes a moving mechanism for assisting in the rapid movement and transfer of the mounting bracket. The moving mechanism includes a second hydraulic cylinder and a lifting moving frame. Two second hydraulic cylinders are bolted to the upper sides of the two mounting brackets on their far sides. The lifting moving frame is connected to the telescopic end of each of the second hydraulic cylinders.

[0011] Furthermore, it is particularly preferred that the mounting bracket also includes a fixing mechanism for securing the mounting bracket. The fixing mechanism includes a second fixing plate, a lifting plate, a fixing rod, a second spring, a fixing frame, and a sliding plate. A fixing rod is connected to the middle position of the upper part of the mounting bracket, and a lifting plate is slidably connected to each fixing rod. A second fixing plate is slidably connected to both the front and rear parts of each lifting plate. The second fixing plate is slidably connected to the mounting bracket. A second spring is connected between each lifting plate and the fixing rod. A fixing frame is connected to the middle position of the upper part of the mounting bracket, and a sliding plate is slidably connected to each fixing frame.

[0012] Furthermore, it is particularly preferred that both the first and second blocking plates are provided with protruding structures to facilitate the operation of the first and second blocking plates.

[0013] Furthermore, it is particularly preferred that each first pulley assembly includes two first pulleys and a first belt, one of which is connected to a first shaft and the other is connected to a second shaft, with the first belt wound between the two first pulleys on the front side and between the two first pulleys on the rear side.

[0014] Furthermore, it is particularly preferred that the second pulley assembly includes two second pulleys and a second belt, one of the second pulleys being connected to a lead screw, the other second pulley being connected to the output shaft of a second servo motor, and the second belt being wound between the two second pulleys.

[0015] The advantages of this invention are: 1. This invention moves the extension end of the first hydraulic cylinder to the right, thereby causing the second sliding frame to slide and unfold to the right. At the same time, the extension frame also slides and unfolds to the right. The third mixing roller drives the second mixing roller to slide and unfold to the right, thereby adapting and adjusting to different soil areas that need improvement, increasing the machine's coverage area, improving the efficiency of soil improvement, and reducing the time spent on repetitive operations.

[0016] 2. In this invention, the rack drives the gear to rotate, which in turn drives the first pulley assembly to rotate. This causes the first shaft to drive the cam to rotate. Under the action of the cam rotation, the first and second baffle plates will open and close intermittently, thereby achieving the effect of intermittent feeding. This avoids the excessive spreading of bamboo sheath biochar at one time, which would lead to soil eutrophication and damage to the soil.

[0017] 3. The present invention drives the lead screw to rotate through the output shaft of the second servo motor, thereby enabling the first and second sliding frames to move automatically, which improves the spreading efficiency of bamboo sheath biochar and avoids the need for manual operation of pushing the first and second sliding frames.

[0018] 4. This invention allows the lifting frame to slide downwards under the action of the second spring by pulling the sliding plate, thus pushing the second fixing plate downwards and inserting it into the soil. This improves the stability of the installation frame and prevents the installation frame from shaking during bamboo sheath biochar sowing, which could cause problems with sowing.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] A soil mixing device using bamboo sheath biochar for soil improvement, such as Figure 1 and Figure 2 As shown, the system includes a mounting frame 1, a first sliding frame 2, a second sliding frame 3, a first servo motor 4, a first mixing roller 5, a feeding mechanism 6, and a unfolding mechanism 7. There are two mounting frames 1. The first sliding frame 2 is slidably connected to the front right side of the left mounting frame 1, and the second sliding frame 3 is slidably connected to the front left side of the right mounting frame 1. The second sliding frame 3 is slidably connected to the first sliding frame 2. Two first servo motors 4 are bolted to the front right side of the left mounting frame 1. The first servo motors 4 are symmetrically distributed front and back, and the output shafts of the first servo motors 4 are all set to the right. The first mixing roller 5 is connected to the output shaft of the first servo motor 4. The first mixing roller 5 is used to turn the soil. The feeding mechanism 6 is provided between the first sliding frame 2 and the second sliding frame 3 for introducing bamboo sheath biochar into the soil. The unfolding mechanism 7 is provided on the first mixing roller 5 for extending and unfolding to adapt to different soil mixing areas.

[0034] To improve soil fertility and improve soil quality, bamboo sheath biochar can be added to the soil. This device can simultaneously add bamboo sheath biochar to the soil and mix the soil and bamboo sheath biochar, allowing for full absorption by the soil. First, the bamboo sheath biochar is placed in the feeding mechanism 6. Then, based on the soil area, the unfolding mechanism 7 is activated, causing the second sliding frame 3 to slide to the right. Next, the feeding mechanism 6 is controlled to feed the material. Then, both the first sliding frame 2 and the second sliding frame 3 are pushed backward. Simultaneously, the first servo motor 4 is activated. The output shaft of the first servo motor 4 drives the first mixing roller 5 to rotate. Both frame 2 and the second sliding frame 3 slide backward, causing the feeding mechanism 6 to move backward and continuously feed material during this backward movement. At the same time, the first mixing roller 5 continuously mixes and stirs the soil and bamboo sheath biochar, enabling the soil and bamboo sheath biochar to mix quickly and improve the soil's absorption efficiency. After the improvement is completed, the feeding mechanism 6 and the first servo motor 4 can be turned off. In summary, the feeding mechanism 6 continuously sows bamboo sheath biochar into the soil, while the unfolding mechanism 7 adapts and adjusts the area of ​​the soil to be improved. Then, during the feeding process, the soil and bamboo sheath biochar are continuously mixed to improve the soil's absorption efficiency.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, the feeding mechanism 6 includes a placement frame 61, an expansion frame 62, a first baffle plate 63, and a second baffle plate 64. The placement frame 61 is bolted to the rear side of the first sliding frame 2, and the expansion frame 62 is bolted to the rear side of the second sliding frame 3. The expansion frame 62 is slidably connected to the placement frame 61. Both the placement frame 61 and the expansion frame 62 are used to place and store bamboo sheath biochar. Two first baffle plates 63 are slidably connected to the bottom of the placement frame 61, and two second baffle plates 64 are slidably connected to the bottom of the expansion frame 62. The first baffle plates 63 can block the bottom of the placement frame 61, and the second baffle plates 64 can block the bottom of the expansion frame 62. Both the first baffle plates 63 and the second baffle plates 64 are provided with protruding structures to facilitate the operator to push the first baffle plates 63 and the second baffle plates 64.

[0036] When improving the soil, bamboo sheath biochar needs to be poured into the placement frame 61 and the expansion frame 62. Then, the first blocking plate 63 and the second blocking plate 64 are pulled a short distance away from each other, so that they no longer obstruct the bottom of the placement frame 61 and the expansion frame 62. Next, the first sliding frame 2 and the second sliding frame 3 are pushed backward. During this pushing process, the bamboo sheath biochar will continuously fall into the soil, thus achieving the effect of rapid spreading of bamboo sheath biochar. During this process, the first servo motor 4 will... The first mixing roller 5 is continuously rotated to quickly mix the sown bamboo sheath biochar with the soil, improving the soil's absorption efficiency. After sowing, the first blocking plate 63 and the second blocking plate 64 are pushed back to their respective sides. In summary, by pulling the first blocking plate 63 and the second blocking plate 64, the bottoms of the placement frame 61 and the expansion frame 62 are no longer obstructed, thus quickly spreading the bamboo sheath biochar into the soil. During the sowing process, the first mixing roller 5 mixes the soil and the bamboo sheath biochar, improving the soil's absorption efficiency.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, the unfolding mechanism 7 includes a connecting frame 71, a first hydraulic cylinder 72, a second mixing roller 73, and a third mixing roller 74. The connecting frame 71 is bolted to the left side of the first sliding frame 2, and the first hydraulic cylinder 72 is connected to the right side of the connecting frame 71. The telescopic ends of the first hydraulic cylinder 72 are all oriented to the right and are connected to the left side of the second sliding frame 3. The second mixing roller 73 is slidably connected to the first mixing roller 5, and the third mixing roller 74 is slidably connected to the right side of the second mixing roller 73. The second mixing roller 73 and the third mixing roller 74 are both used to turn over the soil. The first mixing roller 5 can limit the second mixing roller 73, and the second mixing roller 73 can limit the third mixing roller 74. The right side of the third mixing roller 74 is connected to the left side of the second sliding frame 3.

[0038] When the area of ​​soil requiring improvement is large and the first mixing roller 5 alone is insufficient to cover the soil, the first hydraulic cylinder 72 can be activated. The telescopic end of the first hydraulic cylinder 72 extends to the right, causing the right-side mounting frame 1 to move to the right, the second sliding frame 3 to slide to the right, and the extension frame 62 to slide to the right. Simultaneously, as the right-side mounting frame 1 slides to the right, the third mixing roller 74 will drive the second mixing roller 73 to slide to the right, thereby increasing the mixing range of the first mixing roller 5, the second mixing roller 73, and the third mixing roller 74. Subsequently, as the first sliding frame 2 and the second sliding frame 3 slide backward, bamboo sheath biochar continuously falls from the placement frame 61 and the extension frame 62. The output shaft of the first servo motor 4 will drive the first mixing roller 5, the second mixing roller 73, and the third mixing roller 74 to move to the right. Roller 74 mixes and stirs the soil, allowing it to quickly blend with the bamboo sheath biochar. After the mixing is complete, the extension end of the first hydraulic cylinder 72 retracts to the left, causing the mounting frame 1 on the right to slide to the left, which in turn causes the second sliding frame 3 to slide to the left and the extension frame 62 to slide to the left. Simultaneously, the third mixing roller 74 drives the second mixing roller 73 to slide to the left. In summary, by moving the extension end of the first hydraulic cylinder 72 to the right, the second sliding frame 3 slides to the right and unfolds, while the extension frame 62 also slides to the right. The third mixing roller 74 drives the second mixing roller 73 to slide to the right and unfold, thus adapting and adjusting to different soil areas requiring improvement, improving soil improvement efficiency, and reducing the time spent on repetitive operations.

[0039] like Figure 1 , Figure 7 and Figure 8As shown, it also includes an intermittent mechanism 8, which includes a first fixed plate 81, a first spring 82, a first rotating shaft 83, a second rotating shaft 84, a first pulley assembly 85, a gear 86, a rack 87, and a cam 88. Two first fixed plates 81 are bolted to the opposite sides of the first blocking plates 63, and the opposite sides of the second blocking plates 64 are also bolted to the opposite sides of the first fixed plates 81. First springs 82 are connected between the four first fixed plates 81 on the left and the placement frame 61, and first springs 82 are also connected between the two first fixed plates 81 on the right and the expansion frame 62. Two first springs 82 are connected to each first fixed plate 81. The left side of the placement frame 61 is rotatably connected to the first rotating shaft 83, and the right side of the expansion frame 62 is also rotatably connected to the first rotating shaft 83. The left side of the placement frame 61 is rotatably connected to the second rotating shaft 84, and the right side of the expansion frame 62 is also rotatably connected to the second rotating shaft 84. The second rotating shafts 84 are all located at the first... Below the rotating shaft 83, a first pulley assembly 85 is connected between the first rotating shaft 83 and the second rotating shaft 84 on the left side, and a first pulley assembly 85 is also connected between the first rotating shaft 83 and the second rotating shaft 84 on the right side. The first pulley assembly 85 can make the first rotating shaft 83 and the second rotating shaft 84 rotate simultaneously. The first pulley assembly 85 includes two first pulleys and a first belt. One of the first pulleys is connected to the first rotating shaft 83, and the other first pulley is connected to the second rotating shaft 84. The first belt is wound between the two first pulleys on the front side and between the two first pulleys on the rear side. A cam 88 is connected to the first rotating shaft 83. The cam 88 on the left side can push the first blocking plate 63, and the cam 88 on the right side can push the second blocking plate 64. A gear 86 is connected to the second rotating shaft 84. A rack 87 is connected to the upper rear part of the mounting bracket 1. The rack 87 can mesh with the corresponding gear 86.

[0040] As the first sliding frame 2 and the second sliding frame 3 both slide backward, the gears 86 rotate backward under the action of the rack 87, thereby causing the second rotating shaft 84 to rotate. The second rotating shaft 84 drives the first pulley assembly 85 to rotate, which in turn causes the first rotating shaft 83 to rotate. The rotation of the first rotating shaft 83 drives the cam 88 to rotate. During the rotation of the cam 88, it pushes the first blocking plate 63 and the second blocking plate 64 to slide and unfold. The first fixing plate 81 moves away from the placement frame 61 and the expansion frame 62, and the first spring 82 is stretched. At this time, the bamboo sheath biochar in the placement frame 61 and the expansion frame 62 falls and is scattered into the soil. Afterward, as the cam 88 continues to rotate, the cam 88 no longer squeezes and pushes the first blocking plate 63 and the second blocking plate 64. Under the action of the first spring 82, the first fixing plate 81 moves away from the placement frame 61 and the expansion frame 62. The fixed plate 81 will cause the first blocking plate 63 and the second blocking plate 64 to slide and close, thereby preventing the bamboo sheath biochar from being spread further. During the entire process of the first sliding frame 2 and the second sliding frame 3 sliding backward, the first blocking plate 63 and the second blocking plate 64 will intermittently open and close under the action of the cam 88, thereby achieving the effect of intermittent feeding and preventing the bamboo sheath biochar from being spread too much at once. In summary, the rack 87 drives the gear 86 to rotate, which causes the second rotating shaft 84 to drive the first pulley assembly 85 to rotate, thereby causing the first rotating shaft 83 to drive the cam 88 to rotate. Under the action of the cam 88, the first blocking plate 63 and the second blocking plate 64 will intermittently open and close, thereby achieving the effect of intermittent feeding and preventing the bamboo sheath biochar from being spread too much at once, which would lead to soil eutrophication and damage to the soil.

[0041] like Figure 1 and Figure 9 As shown, it also includes a propulsion mechanism 9, which includes a second servo motor 91, a second pulley assembly 92, and a lead screw 93. The second servo motor 91 is bolted to the upper front of the mounting bracket 1 on the left side. The output shaft of the second servo motor 91 is oriented forward. The lead screw 93 is rotatably connected to the right side of the mounting bracket 1 on the left side. The lead screw 93 is threadedly connected to the first sliding bracket 2. The second pulley assembly 92 is connected between the front end of the lead screw 93 and the output shaft of the second servo motor 91. The second pulley assembly 92 enables the lead screw 93 and the output shaft of the second servo motor 91 to rotate synchronously. The second pulley assembly 92 includes two second pulleys and a second belt. One second pulley is connected to the lead screw 93, and the other second pulley is connected to the output shaft of the second servo motor 91. The second belt is wound between the two second pulleys.

[0042] When soil improvement is needed, the second servo motor 91 can be activated. The output shaft of the second servo motor 91 will drive the second pulley assembly 92 to rotate, thereby causing the lead screw 93 to rotate. During the rotation of the lead screw 93, the first sliding frame 2 will start to slide backward, and the first sliding frame 2 will drive the second sliding frame 3 to slide backward, thus replacing the manual pushing of the first sliding frame 2 and the second sliding frame 3, thereby improving the sowing efficiency. After sowing is completed, the second servo motor 91 can be turned off. In summary, by driving the lead screw 93 to rotate through the output shaft of the second servo motor 91, the first sliding frame 2 and the second sliding frame 3 move automatically, improving the sowing efficiency of bamboo sheath biochar and avoiding the manual operation of pushing the first sliding frame 2 and the second sliding frame 3.

[0043] like Figure 1 and Figure 10 As shown, it also includes a moving mechanism 10, which includes a second hydraulic cylinder 101 and a lifting moving frame 102. The upper sides of the two mounting frames 1, which are far apart from each other, are each connected by bolts to two second hydraulic cylinders 101. The hydraulic cylinders on each mounting frame 1 are symmetrically distributed front and back. The extension and retraction ends of the second hydraulic cylinders 101 are all set downwards. The extension and retraction ends of the second hydraulic cylinders 101 are all connected to the lifting moving frame 102. The lifting moving frames 102 cooperate with each other to help the mounting frame 1 move quickly to the next soil area that needs to be improved.

[0044] When spreading bamboo sheath biochar to improve the soil, it is necessary to control the extension and retraction ends of the second hydraulic cylinder 101 to retract upwards, so that the lifting and moving frame 102 moves upwards. At this time, the lifting and moving frame 102 is no longer in contact with the ground, while the mounting frame 1 is in contact with the ground, which facilitates the spreading of bamboo sheath biochar. After the spreading of a soil area is completed, the extension and retraction ends of the second hydraulic cylinder 101 are controlled to extend downwards to reset, so that the lifting and moving frame 102 moves downwards to reset and contact the ground, thereby assisting the mounting frame 1 to quickly move to the next soil area that needs to be improved.

[0045] like Figure 1 , Figure 11 and Figure 12As shown, it also includes a fixing mechanism 11, which includes a second fixing plate 111, a lifting plate 112, a fixing rod 113, a second spring 114, a fixing frame 115, and a sliding plate 116. A fixing rod 113 is connected to the middle of the upper part of the mounting frame 1, and a lifting plate 112 is slidably connected to each fixing rod 113. A second fixing plate 111 is slidably connected to both the front and rear parts of each lifting plate 112. The bottom of each second fixing plate 111 has a toothed structure, allowing it to be inserted into the soil for fixation. The second fixing plate 111 is connected to the mounting frame 1. The frame 1 is slidably connected. A second spring 114 is connected between the lifting plate 112 and the fixed rod 113. The second spring 114 is wrapped around the fixed rod 113. The top of the second spring 114 is connected to the fixed rod 113, and the bottom of the second spring 114 is connected to the lifting plate 112. A fixed frame 115 is connected to the middle of the upper part of the mounting frame 1. The fixed frame 115 is located on the side of the fixed rod 113 that is far away from each other. A sliding plate 116 is slidably connected to the fixed frame 115. The sliding plate 116 can be engaged with the corresponding lifting plate 112.

[0046] During soil improvement work, to enhance the contact stability between the mounting frame 1 and the ground, the sliding plates 116 are pulled away from each other, disengaging them from the lifting plate 112. Initially, the second springs 114 are compressed. When the sliding plates 116 are no longer engaged with the lifting plate 112, the lifting plate 112 slides downward under the action of the second springs 114, causing the second fixing plate 111 to slide downward and insert into the soil, thus securing the mounting frame 1. After soil improvement is completed, the lifting plates 112 are pulled upward to reset, thereby... The second fixing plates 111 all slide upwards to reset and detach from the soil. At this time, the second springs 114 are compressed. Finally, the sliding plates 116 are pushed to the side closer to each other to reset, so that the sliding plates 116 can be engaged with the lifting plate 112 again. In summary, by pulling the sliding plates 116, the lifting frame is no longer restricted and slides downwards under the action of the second springs 114, pushing the second fixing plates 111 downwards so that the second fixing plates 111 are inserted into the soil. This improves the stability of the mounting frame 1 and prevents the mounting frame 1 from shaking during the sowing of bamboo sheath biochar, which could cause problems with sowing.
