[0032] In this embodiment, the rack 1 of the root stub crushing and ploughing integrated machine is reliably connected with the front-end tractor, ensuring that the two form a stable whole. The cutter shaft 2 of the root stub crushing and ploughing integrated machine rotates quickly, cuts into the soil powerfully, efficiently digs out the root stub from the soil, and crushes it to fine particles meeting the requirements of returning to the field, which are uniformly distributed in the field.

[0033] When the walking wheel 4 part is working in the conventional soil condition, the tractor drives the rotating shaft 3 and the walking wheel 4 to rotate, the ground supporting ring 6 on the circumference of the walking wheel 4 is in contact with the ground to provide stable support for the whole machine, and guarantee the equipment to move straight along the planned route. At this time, the gripping teeth 5 are completely retracted in the through hole 7 of the ground supporting ring 6, and do not affect the normal rolling of the walking wheel 4. When the device is applied to soft soil, the gripping teeth 5 are slid outwardly along the through hole 7 to extend, the gripping teeth 5 can be inserted into the soil with small resistance, and a plurality of gripping teeth 5 are uniformly distributed along the circumference of the walking wheel 4, which effectively increases the friction between the walking wheel 4 and the ground, avoids slipping, and enables the tractor to smoothly pull the integrated machine for continuous operation, ensures the stable operation of the knife shaft 2, and realizes efficient plowing and smoothing of the soft soil plot.

[0034] Through the innovative design of the structure of the walking wheel 4, the root stubble crushing and smoothing integrated machine has the ability to cope with various soil textures, and can meet the plowing and smoothing needs of different farmlands by only switching the working mode through the extension and retraction of the gripping teeth 5, thereby reducing the operation difficulty and cost caused by the change of soil conditions, and widening the application scenarios of the device.

[0035] Further, it further comprises an adjusting disc 8, the adjusting disc 8 is rotationally arranged on the rotating shaft 3, the adjusting disc 8 is provided with an adjusting sliding groove 9, the gripping teeth 5 are provided with a limiting column 10, the limiting column 10 is located in the adjusting sliding groove 9, and the limiting column 10 moves in the adjusting sliding groove 9 after the adjusting disc 8 rotates, which is used to drive the gripping teeth 5 to slide.

[0036] In the embodiment, in order to realize the synchronous sliding of the plurality of gripping teeth 5 outwardly, the adjusting disc 8 is also designed, the adjusting disc 8 is coaxially rotationally arranged on the rotating shaft 3, the adjusting sliding groove 9 on the adjusting disc 8 is a plurality of adjusting sliding grooves 9, which are matched with the number of the gripping teeth 5 and the limiting column 10, and the limiting column 10 is located in the adjusting sliding groove 9.

[0038] In the embodiment, the ground gripping teeth 5 can be extended to different lengths to adapt to different loose soil, so that the ground gripping force of the walking wheel 4 is more suitable for the current ground condition. Specifically, the rotating shaft 3 has a locking hole two 12, the adjusting disc 8 has a plurality of locking holes one 11, the positioning piece three 13 is inserted into the locking hole two 12 and a certain locking hole one 11 at the same time, and the adjusting disc 8 is locked at the current angle.

[0039] In use, the extension length of the ground gripping teeth 5 or no extension can be determined according to the soil condition. Since the plurality of locking holes one 11 are distributed along the circumference of the adjusting disc 8, when the locking hole two 12 corresponds to different locking holes one 11, the angle of the adjusting disc 8 is different, and the position of the limiting column 10 in the adjusting sliding groove 9 is also different, so that the ground gripping teeth 5 are locked at different positions.

[0040] Further, the device further comprises a vertical rod 14, the vertical rod 14 is slidably arranged on the rack 1, and the rotating shaft 3 is rotatably arranged at the bottom end of the vertical rod 14.

[0041] In the embodiment, when the device is connected to different walking units, because the heights of the connection parts of different walking units are different, the inclination angles of the whole device are sometimes different. In order to ensure that the walking wheel 4 can contact the ground at different inclination angles, the vertical rod 14 is designed as a slidable structure, the vertical rod 14 can adjust its vertical position by sliding according to the different distances from the ground, so as to ensure that the walking wheel 4 always contacts the ground, provides stable support for the whole structure, and ensures the stability of the walking process. A plurality of pin holes are designed on the vertical rod 14 in the height direction, and the rack 1 also has corresponding pin holes, so that the vertical rod 14 can be fixed at different heights by inserting a fixed pin.

[0042] Further, the device further comprises a speed reducer 15 and a driving shaft 16, the speed reducer 15 is arranged on the rack 1, the speed reducer 15 has an input shaft 17 and an output shaft 18, the input shaft 17 is used to be connected with a power unit, the driving shaft 16 is rotatably arranged relative to the rack 1, the output shaft 18 is coaxially arranged with the driving shaft 16, and the driving shaft 16 is drivingly connected with the cutter shaft 2 and used to drive the cutter shaft 2 to rotate.

[0043] In the embodiment, the speed reducer 15 is installed on the rack 1, the input shaft 17 of the speed reducer 15 is drivingly connected with a power unit, power is transmitted from the output shaft 18 to the driving shaft 16, and the driving shaft 16 transmits power to the cutter shaft 2 through a chain transmission mechanism, so as to drive the cutter shaft 2 to rotate, provide stable power for the operation of the device and the cutter shaft 2, and ensure the normal operation of the root stub crushing work.

[0044] Further, the knife shaft 2 comprises a shaft body 201, clamping rings 202, a positioning ring 203 and a knife body 204, the clamping rings 202 and the positioning ring 203 are coaxially arranged on the shaft body 201, the clamping rings 202 are arranged in pairs, the positioning ring 203 is located between the two clamping rings 202, the positioning ring 203 is provided with a positioning groove 19, the end of the knife body 204 is embedded in the positioning groove 19, the clamping ring 202 is provided with a positioning hole one 20, the knife body 204 is provided with a positioning hole two 21, the positioning hole one 20 and the positioning hole two 21 are through, and the positioning hole one 20 and the positioning hole two 21 are used for penetrating a positioning member one 22.

[0045] In this embodiment, the traditional installation method of the knife body 204 needs the worker to align the positioning hole one 20 on the clamping ring 202 with the positioning hole two 21 on the knife body 204 by naked eye, and then connect through bolts, the whole process is time-consuming and laborious. The newly designed structure of the knife shaft 2 makes the installation easy and fast. The clamping rings 202 are arranged in pairs, and the positioning ring 203 is clamped in the middle, and the positioning groove 19 on the positioning ring 203 is clearly visible. Align the end of the knife body 204 with the positioning groove 19, because the shape of the positioning groove 19 and the end of the knife body 204 is consistent, the end of the knife body 204 can be easily inserted into the positioning groove 19, and the precise positioning of the knife body 204 on the shaft body 201 is realized instantly. The positioning hole one 20 and the positioning hole two 21 which originally need to be aligned manually are automatically aligned. Penetrate the positioning member one 22 through the two positioning holes one 20 and the positioning hole two 21, and stably fix the knife body 204 between the two clamping rings 202, complete the rapid installation of the knife body 204. According to the same steps, the remaining knife bodies 204 are quickly and accurately installed on the knife shaft 2. The whole process is smooth and efficient, compared with the traditional installation method, it greatly saves time and labor cost.

[0046] The newly added positioning ring 203 and the cooperating positioning groove 19 structure change the installation method of the knife body 204. Only by inserting the end of the knife body 204 into the positioning groove 19, the automatic precise positioning of the knife body 204 can be realized, the positioning hole one 20 and the positioning hole two 21 are automatically aligned, without the need for repeated comparison by naked eye, which greatly improves the accuracy of installation, greatly shortens the installation time, reduces the labor and time cost required for equipment maintenance and replacement of the knife body 204, improves the use efficiency of the equipment, and makes the equipment can be put into production operation faster.

[0047] Further, each of the knife bodies 204 is provided with at least two positioning hole two 21, the positioning hole one 20 is a light hole or a threaded hole, and the positioning member one 22 is a pin body or a bolt.

[0048] In this embodiment, in order to ensure the stable positioning of the cutter body 204, each cutter body 204 has at least two positioning holes 21, and the two points are collectively positioned to improve the stability. When the positioning hole 1 20 is a light hole, the positioning part 1 22 is a pin body, and the pin body is inserted to achieve fastening connection. When the positioning hole 1 20 is a threaded hole, the positioning part 1 22 is a bolt, and the bolt is screwed in to achieve fastening connection. The form of the positioning hole 1 20 can be flexibly determined according to requirements, which improves the adaptability of the cutter shaft 2.

[0049] Further, the positioning groove 19 is matched with the shape of the end of the cutter body 204, and the groove wall of the positioning groove 19 has a guide slope 1901 and a positioning straight surface 1902.

[0050] In this embodiment, the guide slope 1901 of the groove wall of the positioning groove 19 can provide a guiding effect when the cutter body 204 is inserted. The end of the cutter body 204 contacts the guide slope 1901, and the guide slope 1901 guides the cutter body 204 to be inserted into the positioning groove 19 in the correct direction. The positioning straight surface 1902 can provide stable support for the cutter body 204 after the cutter body 204 is fully inserted. The cutter body 204 fully contacts the positioning straight surface 1902, and the positioning straight surface 1902 firmly clamps the end of the cutter body 204, so that the cutter body 204 will not shake or loosen due to accidental factors.

[0051] Further, the clamping ring 202 and the positioning ring 203 have through installation holes 23, and the installation holes 23 are used to pass the positioning part 2 24.

[0052] In this embodiment, a plurality of clamping rings 202 are first sleeved from the end of the shaft body 201 and fixed at the specified position. The positioning ring 203 has a plurality of positioning grooves 19 in the circumferential direction. When it is necessary to install cutter bodies 204 of different specifications or shapes, the positioning groove 19 needs to be matched with the shape. Therefore, the clamping ring 202 and the positioning ring 203 are designed in a split assembly structure.

[0053] When assembling for the first time, the required specification of the positioning ring 203 can be selected. The clamping ring 202 and the positioning ring 203 are sequentially sleeved on the shaft body 201, and then the positioning part 2 24 is simultaneously inserted into the installation holes 23 of the clamping ring 202 and the positioning ring 203. The positioning part 2 24 can be a bolt or a fixed pin, so as to realize the fixation of the positioning ring 203 and the clamping ring 202.

[0054] By designing the clamping ring 202 and the positioning ring 203 in a split assembly structure, the same shaft body 201 and clamping ring 202 can adapt to multiple positioning rings 203 and cutter bodies 204, thereby improving the overall adaptability of the cutter shaft 2.

[0055] Further, the positioning hole one 20 is circular arc-shaped and coaxially arranged relative to the shaft body 201.

[0056] In the embodiment, because the number of the positioning grooves 19 on the different positioning rings 203 is different, the circumferential positions of the positioning hole two 21 on the corresponding tool body 204 can also be changed. In order to adapt the positioning hole one 20 on the clamping ring 202 to the positioning hole two 21 with different circumferential positions, the positioning hole one 20 is designed to be circular arc-shaped and in a strip shape. When the circumferential position of the positioning hole two 21 is changed, the positioning member one 22 can be installed at different positions of the positioning hole one 20, so that the clamping ring 202 can be adapted to different positioning rings 203.
