Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 2As shown in the figure, the present invention provides a combined adjustable disc rake blade, including a fixing ring 1. A first connecting block 11 is fixedly connected to the outer wall of the fixing ring 1. A fixing hole 101 is provided inside the first connecting block 11. A first nut 12 is provided on the inner wall of the fixing hole 101. A first nut 13 is threadedly connected to the outer wall of the first nut 12. During operation, after selecting the position for installing the rake blade, the operator can align the two fixing rings 1 vertically and then tighten and fix the first connecting block 11 through the fixing hole 101 using the first nut 12 and the first nut 13. This allows the inner wall of the fixing ring 1 to contact the rotating shaft and be tightened and fixed on the rotating shaft. Through the above structure, utilizing the characteristics of separate assembly, the device can be quickly disassembled and adjusted to a suitable position according to the situation. Compared with the traditional fixing method, it has higher flexibility, improves the terrain adaptability during operation, and enhances the flexibility and operability of the device.
[0026] like Figure 1 and Figure 3 As shown, the outer wall of the fixing ring 1 is provided with an outer disc 2. The outer disc 2 has an installation hole 201 inside and an inner groove 203 on its outer wall. A second connecting block 21 is fixedly connected to the outer wall of the outer disc 2. The second connecting block 21 has a splicing hole 202 inside and a second nut 22 inside. A second nut 23 is threaded onto the outer wall of the second nut 22. During operation, after the fixing ring 1 is installed and fixed, the operator can continue to install the outer disc 2. After aligning the two outer discs 2 vertically, the second nut 22 and the second nut 23 are used for installation. The cap 23 tightens and fixes the second connecting block 21 through the splicing hole 202, thereby making the inner wall of the outer disk 2 fit and fix the outer wall of the fixing ring 1. The mounting hole 201 is used for subsequent installation and fixation, and the inner groove 203 serves to reserve space for the first connecting block 11 inside the outer disk 2 when tightening and fixing. Through the above structure, by utilizing the characteristics of separate assembly, the outer disk 2 can be installed and fixed after the fixing ring 1 is fixed, so that the device can be quickly disassembled and assembled, and the specifications of the outer disk 2 can be adjusted as needed, thereby improving the adaptability and operability of the device.
[0027] like Figure 1 and Figure 4As shown, the outer wall of the outer disc 2 is provided with a first rake blade 3, and a third nut 31 is slidably connected inside the first rake blade 3. A third nut 32 is threadedly connected to the outer wall of the third nut 31. A second rake blade 4 is provided at the bottom end of the first rake blade 3, and a fourth nut 41 is slidably connected inside the second rake blade 4. A fourth nut 42 is threadedly connected to the outer wall of the fourth nut 41. The outer wall of the third nut 31 is slidably connected to the inner wall of the inner receiving groove 203, and the outer wall of the fourth nut 41 is slidably connected to the inner wall of the inner receiving groove 203. During operation, after the outer disc 2 is fixed, the operator can... The first rake blade 3 is installed through the mounting hole 201. The first rake blades 3 on the left and right sides are tightened and fixed together through the mounting hole 201 using the third nut 31 and the third nut 32. At the same time, the second rake blades 4 on the left and right sides are tightened and fixed together through the mounting hole 201 using the fourth nut 41 and the fourth nut 42 at the lower end of the outer disc 2. Through the above structure, the first rake blade 3 and the second rake blade 4 can be quickly disassembled and assembled by utilizing the assembly structure characteristics, so that the device can be quickly fixed and deployed, improving the stability and convenience of the device.
[0028] like Figure 2 and Figure 3 As shown, a positioning protrusion 5 is fixed to the outer wall of the fixed ring 1, and a positioning groove 501 is provided on the inner wall of the outer disk 2. During operation, when the outer disk 2 is installed on the fixed ring 1, the positioning protrusion 5 on the surface of the fixed ring 1 enables the outer disk 2 to be better positioned during installation. At the same time, when the rotating shaft drives the fixed ring 1 to rotate, the rotation of the fixed ring 1 will drive the positioning protrusion 5 to rotate. When the positioning protrusion 5 rotates, it drives the outer disk 2 to rotate through the positioning groove 501, preventing the outer disk 2 from slipping during rotation. Through the above structure, the positioning protrusion 5 realizes the positioning function during installation. At the same time, the cooperation between the positioning protrusion 5 and the positioning groove 501 prevents the outer disk 2 from sliding on the outer wall of the fixed ring 1 when the fixed ring 1 drives the outer disk 2 to rotate, thus improving the stability and practicality of the device.
[0029] like Figures 1 to 3 As shown, the inner wall of the fixed ring 1 is provided with a splicing ring 601, and the inner wall of the splicing ring 601 is fixed with a splicing groove 6. During operation, when the fixed ring 1 is installed, the splicing groove 6 inside the splicing ring 601 will fit against the rotating shaft. At the same time, when tightening and fixing, the friction between the fixed ring 1 and the rotating shaft is increased, so that the rotating shaft can drive the fixed ring 1 to rotate when it rotates. Through the above structure, the splicing groove 6 increases the friction of the fixed ring 1 on the rotating shaft, improves the stability of the fixed ring 1 when rotating, and improves the stability of the device.
[0030] like Figures 1 to 4As shown, the outer wall of the first rake blade 3 is provided with rake teeth 301, which have various shapes and specifications. During operation, the first rake blade 3 rotates, causing the rake teeth 301 to contact the soil and turn over the soil structure. Different shapes and specifications allow the operator to adjust the shape of the installed rake teeth 301 according to the situation, thereby improving work efficiency. Through the above structure, the rake teeth 301 realize the function of turning over the soil structure. At the same time, the different shapes and specifications of the rake teeth 301 also provide more options for the device during installation. The structure of the rake teeth 301 in the four parts can be flexibly adjusted as needed, reducing production costs and improving the flexibility and adaptability of the device.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, the splicing groove 6 is made of rubber, while the first rake blade 3 and the second rake blade 4 are both made of wear-resistant metal. During operation, the rubber material of the splicing groove 6 ensures that the splicing groove 6 and the rotating shaft remain in close contact after installation, while also increasing the friction between the fixing ring 1 and the rotating shaft. The wear-resistant metal material of the first rake blade 3 and the second rake blade 4 improves durability and adaptability, enabling them to cope with different soil conditions. Through the above structure, the rubber material of the splicing groove 6 increases the friction between the fixing ring 1 and the rotating shaft, improving the stability of the fixing ring 1 during rotation. The wear-resistant metal material of the first rake blade 3 and the second rake blade 4 improves the durability of the device, reduces maintenance costs, and increases work efficiency.
[0032] During operation, after selecting the installation position of the rake blades, the operator aligns the two fixing rings 1 vertically and uses the first nut 12 and the first screw 13 to tighten and fix the first connecting block 11 through the fixing hole 101, thereby making the inner wall of the fixing ring 1 contact the rotating shaft and be tightened and fixed on the rotating shaft. After installing and fixing the fixing rings 1, the operator can continue to install the outer discs 2. After aligning the two outer discs 2 vertically, the operator uses the second nut 22 and the second screw 23 to tighten and fix the second connecting block 21 through the splicing hole 202, thereby making the inner wall of the outer disc 2 contact the fixing ring 1. The outer wall is fitted and fixed, with mounting holes 201 for subsequent installation and fixing. The inner groove 203 serves to reserve space for the first connecting block 11 inside the outer disc 2 during tightening and fixing. During operation, after the outer disc 2 is fixed, the operator can install the first rake blade 3 through the mounting holes 201. The third nut 31 and the third nut 32 are used to tighten and fix the first rake blades 3 on the left and right sides together through the mounting holes 201. At the same time, the fourth nut 41 and the fourth nut 42 are used to tighten the second rake blades 4 on the left and right sides at the lower end of the outer disc 2 through the mounting holes 201. The outer disc 2 is fixedly spliced together. During operation, when the outer disc 2 is installed on the fixed ring 1, the positioning protrusion 5 on the surface of the fixed ring 1 ensures better positioning of the outer disc 2 during installation. Simultaneously, when the rotating shaft drives the fixed ring 1 to rotate, the rotation of the fixed ring 1 drives the positioning protrusion 5 to rotate. The rotation of the positioning protrusion 5, through the positioning groove 501, drives the outer disc 2 to rotate, preventing slippage during rotation. During operation, when the fixed ring 1 is being installed, the splicing groove 6 inside the splicing ring 601 will fit against the rotating shaft. Simultaneously, during tightening and fixing, the friction between the fixed ring 1 and the rotating shaft is increased, making the rotation... When the shaft rotates, it can drive the fixed ring 1 to rotate. During operation, the first rake blade 3 rotates, causing the rake teeth 301 to contact the soil and turn over the soil structure. Different shapes and specifications allow the workers to adjust the shape of the installed rake teeth 301 according to the situation, improving work efficiency. During operation, the rubber material of the splicing groove 6 ensures that the splicing groove 6 and the rotating shaft remain in close contact after installation, while increasing the friction between the fixed ring 1 and the rotating shaft. The first rake blade 3 and the second rake blade 4 are made of wear-resistant metal material, which improves durability and adaptability, enabling the first rake blade 3 and the second rake blade 4 to cope with different soil conditions.
