[0027] ReferenceFigs. 1-3 For the first embodiment of the utility model, a kind of root stub comminution ploughing integrated machine cutter shaft is proposed, including shaft body 1, clamping ring 2, positioning ring 3 and cutter body 4, the clamping ring 2 and the positioning ring 3 are coaxially arranged on the shaft body 1, the clamping ring 2 is arranged in pairs, the positioning ring 3 is located between the two clamping ring 2, the positioning ring 3 has positioning groove 5, the cutter body 4 end is embedded in the positioning groove 5, the clamping ring 2 has positioning hole one 6, the cutter body 4 has positioning hole two 7, the positioning hole one 6 and the positioning hole two 7 are through, the positioning hole one 6 and the positioning hole two 7 are used to be commonly equipped with positioning piece one 8.
[0028] In the embodiment, the traditional cutter body 4 installation mode needs staff to align positioning hole one 6 on clamping ring 2 and positioning hole two 7 on cutter body 4 with naked eye, then is connected by bolt, entire process is time-consuming and laborious.Newly designed cutter shaft structure, installation becomes easy and fast.Cutting ring 2 is distributed in pairs, and positioning ring 3 is clamped in the middle, and the positioning groove 5 on the positioning ring 3 is clearly visible.Cutter body 4 end is aligned with positioning groove 5, since the shape of positioning groove 5 and cutter body 4 end is consistent, cutter body 4 end can be easily inserted into positioning groove 5, and accurate positioning of cutter body 4 on shaft body 1 is realized instantly.Originally, positioning hole one 6 and positioning hole two 7 need to be aligned manually, and positioning piece one 8 is inserted into two positioning holes one 6 and positioning holes two 7, and cutter body 4 is stably fixed between two clamping rings 2, and the quick installation of cutter body 4 is completed.According to the same steps, the remaining cutter body 4 is quickly and accurately installed on the cutter shaft.The whole process is smooth and efficient, compared with traditional installation mode, time and labor cost are greatly saved.
[0029] New positioning ring 3 and cooperating positioning groove 5 structure change the installation mode of cutter body 4.Only cutter body 4 end is inserted into positioning groove 5, the automatic accurate positioning of cutter body 4 can be realized, and positioning hole one 6 and positioning hole two 7 are automatically aligned, without the need of repeated comparison with naked eye, the accuracy of installation is greatly improved, the installation time is greatly shortened, the labor and time cost required for equipment maintenance and cutter body 4 replacement is reduced, the use efficiency of equipment is improved, and the equipment can be put into production operation faster.
[0030] Further, each of the cutter body 4 has at least two positioning hole two 7, the positioning hole one 6 is a light hole or a threaded hole, and the positioning piece one 8 is a pin body or a bolt.
[0031] In this embodiment, in order to ensure the stable positioning of the cutter body 4, each cutter body 4 has at least two positioning holes two 7, and the two points are jointly positioned to improve the stability. When the positioning hole one 6 is a light hole, the positioning part one 8 is a pin body, and the pin body is inserted to realize the fastening connection. When the positioning hole one 6 is a threaded hole, the positioning part one 8 is a bolt, and the bolt is screwed in to realize the fastening connection. The form of the positioning hole one 6 can be flexibly determined according to the requirements, which improves the adaptability of the cutter shaft.
[0032] Further, the positioning groove 5 is matched with the shape of the end of the cutter body 4, and the groove wall of the positioning groove 5 has a guide slope 501 and a positioning straight surface 502.
[0033] In this embodiment, the guide slope 501 of the positioning groove 5 groove wall can provide a guiding effect when the cutter body 4 is inserted. The end of the cutter body 4 contacts the guide slope 501, and the guide slope 501 guides the cutter body 4 to be inserted into the positioning groove 5 in the correct direction. The positioning straight surface 502 can provide stable support for the cutter body 4 after the cutter body 4 is fully inserted. The cutter body 4 fully contacts the positioning straight surface 502, and the positioning straight surface 502 firmly clamps the end of the cutter body 4, so that the cutter body 4 will not shake or loosen due to accidental factors.
[0034] Further, the clamping ring 2 and the positioning ring 3 have a through mounting hole 9, and the mounting hole 9 is used to pass the positioning part two 10.
[0035] In this embodiment, a plurality of clamping rings 2 are first sleeved from the end of the shaft body 1 and fixed at the specified position. The positioning ring 3 has a plurality of positioning grooves 5 in the circumferential direction. When it is necessary to install cutter bodies 4 of different specifications or shapes, the positioning groove 5 needs to match the shape, which requires the selection of positioning rings 3 with different numbers and shapes of positioning grooves 5. Therefore, the clamping ring 2 and the positioning ring 3 are designed in a split assembly structure.
[0036] When assembling for the first time, the required specification of the positioning ring 3 can be selected. The clamping ring 2 and the positioning ring 3 are sequentially sleeved on the shaft body 1, and then the positioning part two 10 is simultaneously inserted into the mounting hole 9 of the clamping ring 2 and the positioning ring 3. The positioning part two 10 can be a bolt or a fixed pin, so as to realize the fixation of the positioning ring 3 and the clamping ring 2.
[0037] By designing the clamping ring 2 and the positioning ring 3 in a split assembly structure, the same shaft body 1 and clamping ring 2 can adapt to multiple positioning rings 3 and cutter bodies 4, thereby improving the overall adaptability of the cutter shaft.
[0038] Further, the positioning hole one 6 is a circular arc, and is coaxially arranged relative to the shaft body 1.
[0039] In the embodiment, the number of positioning grooves 5 on different positioning rings 3 is different, so the circumferential position of the positioning hole two 7 on the corresponding tool body 4 may also change. In order to adapt the positioning hole one 6 on the clamping ring 2 to the positioning hole two 7 with different circumferential positions, the positioning hole one 6 is designed as an arc shape, which is a strip as a whole. When the circumferential position of the positioning hole two 7 changes, the positioning member one 8 can be installed at different positions of the positioning hole one 6, so that the clamping ring 2 can adapt to different positioning rings 3.
[0040] Further, the tool body 4 is a plurality of tool bodies 4 arranged in a circle along the circumferential direction of the shaft body 1, and a plurality of circles of the tool body 4 are distributed along the length direction of the shaft body 1.
[0041] In the embodiment, the tool body 4 is designed in a circle and a plurality of circles are arranged along the length direction of the shaft body 1, so that the tool body 4 can cover a large enough area, ensuring the effectiveness and efficiency of cleaning the stubble, and the soil can be plowed and the turned-up stubble can be crushed for subsequent field treatment.
[0042] Further, the plurality of circles of the tool body 4 distributed along the length direction of the shaft body 1 are distributed in a spiral shape.
[0043] In the embodiment, when the shaft body 1 rotates, the tool body 4 distributed in a spiral shape can cut into the soil at different times and positions, and can also make the soil flow in the axial direction, thereby reducing the resistance of the soil to the tool body 4, and ultimately facilitating better plowing of the soil.
[0044] Further, the tool body 4 is in the shape of "7".
[0045] In the embodiment, the curved shape of the tool body 4 can provide a suitable angle of entry into the soil. When the shaft rotates, the front end portion of the tool body 4 in the shape of "7" can cut into the soil with relatively small resistance, more easily penetrate the soil, and better adapt to different textures and hardness of the soil with the continuous rotation of the shaft body 1, achieving a stable soil entry process.
[0046] Further, the shaft body 1 is a hollow shaft.
[0047] In the embodiment, the shaft body 1 is designed as a hollow structure, which can effectively reduce the weight of the shaft body 1 itself. The lighter shaft body 1 requires relatively small driving force during rotation, which can reduce the power demand of the equipment. It can also reduce the amount of material used, reduce production costs, and improve material utilization efficiency.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
