Technical Field

[0001] The utility model relates to the field of agricultural machinery, and specifically provides a double-row tobacco stalk pulling machine. Background Art

[0002] Tobacco is an important cash crop in my country and has special economic value. The residue left after tobacco leaves are picked, namely the tobacco stalks, have a high degree of lignification and are not easy to rot. They usually contain tobacco pathogens. If they remain in the tobacco field for a long time, they will pollute the soil of the tobacco field and are not conducive to the growth of subsequent crops. Therefore, it is necessary to clean up the remaining tobacco stalks in the tobacco field in time. The traditional operation of tobacco stalk recycling requires manual digging. The whole processing process is time-consuming and labor-intensive, and the labor cost is high. Most of the existing tobacco stalk pulling machines are cutting or shoveling type, and most of them are single-row and single-ridge operations, which cannot adapt well to the situation of different ridge widths and changes in ridge gaps.

[0032] The transmission method of the transmission component 4 includes but is not limited to sprocket transmission or gear rack transmission. By moving the rotary tiller 6 arranged on the cutter shaft 5 and controlling the spacing between the rotary tillers 6, the stalk pulling machine can be adjusted to fields with different ridge spacings. It has strong adaptability and can realize multi-ridge stalk pulling operations, greatly improving the efficiency of stalk pulling operations.

[0033] Embodiment 1:

[0034] like Figure 2 As shown, this embodiment provides a specific sliding structure of a rotary tiller 6 and its own component structure. At the same time, the transmission structure of the transmission component 4 is connected to the center of the blade shaft 5. Two sets of rotary tillers 6 are provided, which are respectively installed on both sides of the blade shaft 5, and are used for cultivating land with a wide ridge width. Figure 4 and Figure 5 As shown, the rotary tiller 6 includes a blade mounting plate 61 and a rotary tiller blade 62. The mounting plate 61 is slidably mounted on the blade shaft 5. The rotary tiller blade 62 is long and strip-shaped. The rotary tiller blade 62 is evenly arranged on the mounting plate 61 around the axis of the blade shaft 5. The two ends of the rotary tiller blade 62 are respectively arranged on two mounting plates 61. The mounting plate 61 is provided with a mounting block 64 for mounting the rotary tiller blade 62. The rotary tiller blade 62 can be installed by bolts. When the rotary tiller blade 62 is damaged and needs to be replaced, the rotary tiller blade 62 can be easily replaced. At the same time, it is preferred that three rotary tiller blades 62 are arranged on one mounting plate 61 to effectively ensure the stalk pulling effect and the strength of the rotary tiller 6 when tilling and pulling stalks.

[0035] In this arrangement, when the cutter shaft 5 rotates, the blade is driven to rotate around the cutter shaft 5 and penetrate into the soil, cutting the soil and lifting the target stalk. The rotary tiller 6 connected by the mounting plate 61 also avoids the structure in the transmission component 4 from leaking out, preventing weeds and other debris from entangled with parts such as chains in the transmission component 4.

[0036] Furthermore, a support plate 63 is slidably provided on the blade shaft 5, and the rotary tillage blade 62 is provided on the end points of the support plate 63. In the above case, the support plate 63 is triangular, and the triangle has stability. The three ends of the triangular support plate 63 respectively support the rotary tillage blade 62 to prevent the blade from being broken and damaged due to excessive stress during stalk pulling operation when the blade is too long.

[0037] The driving rod assembly 7 includes two driving disks 71 fixedly sleeved on the blade shaft 5, a driving rod 72 is arranged between the driving disks 71, the driving rod 72 passes through the mounting disk 61 along the axis direction of the blade shaft 5, and the mounting disk 61 can slide on the blade shaft 5 along the length direction of the driving rod 72. It is preferred to arrange a plurality of driving rods 72 on the driving disk 71 to ensure that the driving disk 71 can better drive the mounting disk 61 to rotate, and can also evenly distribute the torque to each driving rod 72, thereby ensuring the strength of the driving rod assembly 7.

[0038] Furthermore, in order to ensure that the rotary tiller 6 can be fixed after being set to the required position, and to avoid the position of the rotary tiller 6 from being offset during operation, at least one of the driving rods 72 is provided with a limiting structure, wherein one limiting structure is: the driving rod 72 is a screw structure, threadedly connected to the mounting plate 61, and the mounting plate 61 slides relative to other driving rods 72 through the self-rotation of the threaded driving rod 72. Another limiting structure is: limiting holes 73 for placing limiting pins are evenly arranged on the driving rod 72, and the sliding of the rotary tiller 6 can be limited by inserting limiting components such as limiting pins into the limiting holes 73. At this time, it should be noted that when the two mounting plates 61 of the rotary tiller 6 are respectively in the two driving rod assemblies 7, the limiting components can be respectively arranged on different sides of the two mounting plates; when only one side of the mounting plate 61 is arranged in the driving rod assembly 7, it is necessary to arrange limiting components on both sides of the mounting plate 61 to avoid the adjusted rotary tiller 6 from sliding and offsetting on the blade shaft 5 during rotation.

[0039] Embodiment 2:

[0040] The structure of the transmission component 4 of this embodiment is not completely the same as that of the first embodiment. Figure 3 As shown, the transmission structure is connected to one end of the blade shaft 5, and is used for small-interval cultivated land with a small ridge width or cultivated land with a wide ridge width and wide intervals, such as a cigar field. As in the first embodiment, two groups of rotary tillers 6 are arranged on the blade shaft 5, and the mounting plates 61 of the two rotary tillers 6 are close to each other, and mounting blocks 64 for mounting rotary tiller blades 62 are arranged on both sides. After the positions of the two groups of rotary tillers 6 are adjusted according to the ridge width, a rotary tiller blade 62 of a specific length is also installed between the two groups of rotary tillers 6, and the two groups of rotary tillers 6 are combined into one group of rotary tillers 6 with an extended length.

[0041] Embodiment three:

The tillage depth adjustment mechanism 8 includes a first telescopic support rod 81 provided at the bottom of the frame 1. A roller 82 is provided at the bottom of the first telescopic rod. The support rod rotates with the frame 1.

[0043] Specifically, by adjusting the height of the first telescopic support rod 81, the center of gravity of the frame 1 and the angle of the rotary tiller 6 can be adjusted. The longer the first telescopic support rod is, the shallower the tillage depth of the rotary tiller 6 is; the shorter the first telescopic support rod is, the deeper the tillage depth of the rotary tiller 6 is. The tillage depth is adjusted according to the actual soil conditions on site to ensure a good stalk pulling rate.

[0044] Furthermore, a leveling rod 83 is provided between the vehicle connecting rod 2 and the frame 1 , and both ends of the leveling rod 83 are rotatably connected to the frame 1 and the vehicle connecting rod 2 , respectively, and both ends of the leveling rod 83 are provided with a rotation locking structure.

[0045] In this solution, during the telescopic adjustment of the first telescopic support rod 81, by adjusting the angle of the leveling rod 83, the stability of the connection between the frame 1 and the vehicle can be ensured, thereby preventing excessive force on the joint between the vehicle connecting rod 2 and the vehicle when the first telescopic support rod 81 is shortened or preventing the first telescopic support rod 81 from being unable to extend.

[0046] Furthermore, a second telescopic support rod 84 is provided on one side of the bottom of the frame 1 near the blade shaft 5. The second telescopic support rod 84 is in a shortened state when the device is in the field for rotary tillage operation, and is in an extended state when driving out of the field, replacing the rotary tillage blade 6 to support the frame 1, so as to facilitate the transportation of the device.

[0047] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
