[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] Example 1
[0027] The embodiment of the utility model provides a rotary tillage disc harrow mixer.
[0028] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a rotary tiller body 1, which is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It is mainly composed of a frame, a transmission part, a cutter shaft, a blade, a cover and other parts. The frame is the skeleton of the entire rotary tiller, which is used to install and support other parts; the transmission part is responsible for transmitting the power of the tractor to the cutter shaft, and common methods include universal joint transmission; the cutter shaft is the component for installing the blade, and when working, the cutter shaft rotates to drive the blade to cut the soil; the blade has various shapes, such as scimitar shape and straight blade shape, and its material usually has high hardness and wear resistance; the cover is installed on the upper and side of the rotary tiller, and mainly plays the role of preventing soil and debris from splashing and injuring people and protecting internal components. A connecting frame 2 is fixed to one end of the rotary tiller body 1, and the other end of the connecting frame 2 is connected to the driving frame 4 by a pin 3. The other end of the driving frame 4 is rotatably connected to the disc harrow body 5, and a traction frame 6 is provided at the end of the rotary tiller body 1 away from the disc harrow body 5;
[0029] The disc harrow body 5 is an agricultural implement used for field preparation, mainly consisting of a harrow group, a harrow frame, a traction or suspension device, etc. The harrow group is the core part of the disc harrow, which is composed of multiple disc harrow blades. The harrow blades are generally concave discs with sharp edges. The harrow frame is used to install and support the harrow group, and serves to connect the traction device or suspension device to ensure that the disc harrow can be stably dragged forward during operation.
[0030] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth mentioning that one end of the connecting frame 2 is fixed to one end of the rotary tiller body 1, the inner wall of the other end of the connecting frame 2 is in contact with the outer surface of one end of the driving frame 4, the cross-section of the connecting frame 2 is U-shaped, and the other end of the driving frame 4 is rotatably connected to the middle part of one end of the disc harrow body 5, and the rotary tiller body 1 is arranged between the disc harrow body 5 and the traction frame 6.
[0031] When the present invention is in use: first, the fixed connecting frame 2 of the rotary tiller body 1 is connected to the rotating connecting driving frame 4 of the disc harrow body 5 through the pin 3. Then, the connecting shaft of the rotary tiller body 1 is connected to the output shaft of the agricultural tiller, and the traction frame 6 is connected to the agricultural tiller. Driven by the agricultural tiller, the rotary tiller body 1 begins to move, and its rotating blades rotate under the drive of the agricultural tiller, first performing a rotary loosening operation on the farmland. Subsequently, the disc harrow body 5 that follows the movement, relying on its own gravity, cuts into the soil with the cutting edge of the harrow blade, cuts off grass roots or crop residues, chops up the plowed soil strips, and causes the soil to rise slightly along the concave surface of the harrow blade, and then falls. Such an operation process achieves the effect of efficient land preparation. The rotary tiller disc harrow mixer reduces the number of round trips of the agricultural machinery in the field, which not only saves time and resources such as fuel, but also reduces the degree of compaction of the soil by the agricultural machinery, thereby achieving the effect of improving the use effect of the rotary tiller disc harrow mixer.
[0032] Example 2
[0033] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , based on the first embodiment, a convenient assembly function is added;
[0034] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth mentioning that a pin hole 7 is provided at the tail of the pin 3, a slide groove 8 is provided on one side of the connecting frame 2, and a connecting structure is provided on the inner wall of the slide groove 8. The connecting structure includes a sliding plate 9, a spring 10 is fixed to the upper end of the sliding plate 9, a limiting frame 11 is fixed in the middle of the sliding plate 9, and a pull ring 12 is fixed to the upper end of the limiting frame 11.
[0035] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4It is worth mentioning that the outer surface of the sliding plate 9 is slidably connected to the inner wall of the slide groove 8, the cross-section of the sliding plate 9 is a circular setting, the middle part of the limit frame 11 is fixed to the middle of the sliding plate 9, the limit frame 11 passes through the middle of the slide groove 8, the outer surface of the pin 3 is in contact with the inner wall of the connecting frame 2 and the driving frame 4, the outer surface of one end of the limit frame 11 is in contact with the inner wall of the pin hole 7, and the other end of the limit frame 11 is fixed to the middle of the pull ring 12. The vertical section of the pull ring 12 is a circular ring setting, the pin hole 7 passes through the tail of the pin 3, the lower end of the spring 10 is fixed to the upper end of the sliding plate 9, the upper end of the spring 10 is fixed to the inner wall of the upper end of the slide groove 8, and the spring 10 is sleeved on the limit frame 11.
[0036] During use, the present invention moves by manually pulling the pull ring 12, thereby driving the limiting frame 11, which is fixedly connected to the pull ring 12, to move. During this movement, the limiting frame 11 drives the sliding plate 9, to which it is fixed, to slide under the limiting and guiding action of the chute 8. As the sliding plate 9 slides, it compresses the spring 10 fixed at its upper end, thereby creating a movable compression space for the limiting frame 11. When the limiting frame 11 moves to contact the inner wall of the pin hole 7 of the pin 3, the pin 3 is trapped between the connecting frame 2 and the driving frame 4, thereby connecting the rotary tiller body 1 to the disc harrow body 5. When the limiting frame 11 slides out of the inner wall of the pin hole 7 of the pin 3, the pin 3 can be removed, and the connecting frame 2 can then be separated from the driving frame 4, thereby separating the rotary tiller body 1 from the disc harrow body 5. This design achieves the effect of convenient assembly. The connection and separation of the rotary tiller and the disc harrow can be completed by gently pulling the pull ring 12, which brings great convenience to the staff and thus improves the convenience of using the rotary tiller disc harrow mixer.
