Description

Technical Field

[0001] This utility model relates to a auger intermediate section suspension in the field of auger technology. Background Technology

[0002] The prior art discloses an auger suspension system with publication number CN209396438U and publication date of September 17, 2019. This system includes an upper suspension body and a lower suspension body fixed to both ends of the upper suspension body via bolts. A fixing hole for fixing the auger's central shaft is provided between the upper and lower suspension bodies. A wear-resistant rubber sleeve is installed in the middle of the fixing hole. The wear-resistant rubber sleeve has a circular cross-section and is divided into an upper rubber sleeve and a lower rubber sleeve. The upper and lower rubber sleeves are located on the inner wall of the upper semi-circular fixing hole of the upper suspension body and in the lower semi-circular fixing hole of the lower suspension body, respectively. This invention has a simple structure and is easy to operate: by setting a device to fix the auger's central shaft at its center and fixing this device to a horizontal iron plate above the upper auger groove, the iron plate is connected to the lifting column by bolts. This achieves effective gravity lifting of the auger, and the height of the auger can be controlled by adjusting the spiral depth of the bolts in the built-in threaded holes. However, this structure is inconvenient to install and disassemble, and its overall lateral width is larger, which can easily cause blockages in the transportation of materials, making material transportation difficult. Utility Model Content

[0003] The purpose of this utility model is to provide a auger middle section suspension that is easier to install and disassemble, and has a relatively flat and straight overall structure that will not cause blockage to the transportation of materials.

[0004] To achieve the above objectives, this utility model provides a auger intermediate section suspension, including a vertical clamping frame, the lower end of which is connected to the auger shaft, the upper end of which is connected to a hanger, and the hanger is fixedly connected to the inner wall of the auger housing.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: by connecting the lower end of the vertical clamping frame to the auger shaft and the upper end of the vertical clamping frame to the hanger, which in turn connects to the auger housing, the auger shaft is suspended in the middle of the auger housing. With the effective support of the vertical clamping frame and the hanger, it will not sag over time, preventing the auger blades from contacting and wearing out on the auger housing, thus improving the auger's service life. Installation and disassembly are also more convenient, and the overall structure is relatively flat and straight, preventing blockages in material transportation.

[0006] As a further improvement of this utility model, the vertical clamping frame includes a pair of vertical clamping plates, which are fixedly connected to each other. The lower end of the vertical clamping plates is machined with a hemispherical clamp, and a wear-resistant bushing is provided between the hemispherical clamps. The wear-resistant bushing is installed on the auger shaft. The upper end of the vertical clamping plates is machined with a connecting horizontal plate, which is connected to the hanger.

[0007] The vertical clamps are fixed in place, while the hemispherical clamps hug each other to form a complete sphere, which clamps the auger shaft in the middle. The upper end of the vertical clamps is connected to the hanger through the connecting horizontal plate, and the hanger is connected to the auger shell, thus effectively supporting the auger shaft. Furthermore, the overall structure of the vertical clamps and hemispherical clamps is flat and will not affect the passage of materials.

[0008] As a further improvement of this utility model, the hanger includes a crossbeam, the bottom ends of which are respectively connected to the horizontal side of an L-shaped mounting piece, the vertical side of the L-shaped mounting piece is fixedly connected to the inner wall of the auger shell, and the bottom of the crossbeam is fixedly connected to the connecting horizontal plate.

[0009] In this way, the crossbeam is fixedly connected to the inner wall of the auger shell through L-shaped mounting parts and is located at the top of the auger shell. The crossbeam is connected to the vertical clamping plate through connecting horizontal plate, so that the entire suspension is T-shaped inside the auger shell, flat in overall shape, and basically does not occupy space inside the auger shell, does not affect the passage of materials, and the suspension is fixed at two points, so the overall structure has better stability.

[0010] As a further improvement of this utility model, the wear-resistant bushing includes an inner bushing and an outer bushing, wherein the inner bushing is made of polytetrafluoroethylene and the outer bushing is made of nylon.

[0011] This double-layer bushing structure provides better wear resistance and reduces wear between the auger shaft and the bushing.

[0012] As a further improvement of this utility model, the vertical clamping plates, the connecting horizontal plates and the crossbeam, the horizontal side of the L-shaped mounting piece and the crossbeam, and the vertical side of the L-shaped mounting piece and the auger shell are all fixedly connected by bolts and nuts.

[0013] The components are connected by bolts and nuts, making installation and disassembly simpler and more convenient.

[0014] As a further improvement of this utility model, an oblong hole is provided on the vertical side of the L-shaped mounting part, and an oblong hole is also provided on the crossbeam.

[0015] During installation, the hanging height can be finely adjusted by adjusting the relative position of the waist-shaped hole on the vertical side of the L-shaped mounting piece and the screw hole on the auger housing, thus ensuring that the height of all hangings in the entire auger is consistent. The horizontal position of the vertical clamping frame can also be finely adjusted by adjusting the relative position of the waist-shaped hole on the crossbeam and the screw hole on the connecting cross plate, thus preventing the hanging from shifting horizontally and failing to install with the auger shaft.

[0022] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-5 The auger intermediate section suspension shown includes a vertical clamping frame. The lower end of the vertical clamping frame is connected to the auger shaft 3, and the upper end of the vertical clamping frame is connected to the hanger. The hanger is fixedly connected to the inner wall of the auger housing 2.

[0023] The vertical clamping frame includes a pair of vertical clamping plates 1, which are fixedly connected to each other. The lower end of the vertical clamping plate 1 is machined with a hemispherical clamp 4, and a wear-resistant bushing is provided between the hemispherical clamps 4. The wear-resistant bushing is installed on the auger shaft 3. The upper end of the vertical clamping plate 1 is machined with a connecting horizontal plate 7, which is connected to the hanger.

[0024] The hanger includes a crossbeam 6, the bottom ends of which are connected to the horizontal sides of an L-shaped mounting piece 8. The vertical side of the L-shaped mounting piece 8 is fixedly connected to the inner wall of the auger housing 2. The bottom of the crossbeam 6 is fixedly connected to a connecting horizontal plate 7. The wear-resistant bushing includes an inner bushing 12 and an outer bushing 10. The inner bushing 12 is made of polytetrafluoroethylene, and the outer bushing 10 is made of nylon.

[0025] The vertical clamping plates 1, the connecting horizontal plate 7 and the horizontal beam 6, the horizontal side of the L-shaped mounting piece 8 and the horizontal beam 6, and the vertical side of the L-shaped mounting piece 8 and the auger housing 2 are all fixedly connected by bolts 9 and nuts 11. The vertical side of the L-shaped mounting piece 8 is provided with a waist-shaped hole 13, and the horizontal beam 6 is also provided with a waist-shaped hole 13.

[0026] In this utility model, the vertical clamping frame comprises two parts, each consisting of a vertical clamping plate 1, a connecting horizontal plate 7, and a hemispherical clamping hoop 4, while the hanger consists of a horizontal beam 6 and a pair of L-shaped mounting parts 8.

[0027] The wear-resistant bushing is installed on the auger shaft 3. A pair of vertical clamping plates 1 are fixed back to back by bolts 9 and nuts 11. The hemispherical clamp 4 then hugs each other to form a complete sphere, and the wear-resistant bushing is completely wrapped and clamped between the two. The wear-resistant bushing is installed on both sides. The outer bushing 10 is inside the hemispherical clamp 4, and the inner bushing 12 is inside the outer bushing 10. The auger shaft 3 is installed in the inner bushing 12.

[0028] The connecting plate 7 is connected to the bottom of the crossbeam 6 by bolts 9 and nuts 11. The two ends of the crossbeam 6 are fixedly connected to the horizontal side of the L-shaped mounting piece 8 by bolts 9 and nuts 11. The vertical side of the L-shaped mounting piece 8 is connected to the upper part of the inner wall of the auger shell 2, so that the two ends of the whole hanger are effectively supported.

[0029] The hanging height can be finely adjusted by adjusting the relative position of the waist-shaped hole 13 on the vertical side of the L-shaped mounting piece 8 and the screw hole on the auger housing 2, thereby ensuring that the height of all hanging pieces in the entire auger is consistent. The horizontal position of the vertical clamping frame can also be finely adjusted by adjusting the relative position of the waist-shaped hole 13 on the crossbeam 6 and the screw hole on the connecting cross plate 7, thereby preventing the hanging piece from shifting horizontally and failing to install with the auger shaft 3. The L-shaped mounting piece 8 can also be made to fit against the inner wall of the auger housing 2 by adjusting the relative position of the waist-shaped hole 13 at both ends of the crossbeam 6 and the screw hole on the horizontal side of the L-shaped mounting piece 8.

[0030] After all components are installed, the hanger and vertical clamping frame together form a T-shaped structure. Specifically, the vertical clamping plate 1 and the hemispherical clamping hoop 4 are flat and vertically aligned, located in the middle of the auger shell 2's cross-section. Meanwhile, the horizontal beam 6, connecting horizontal plate 7, and L-shaped mounting piece 8 are flat and horizontally aligned, located at the upper part of the auger shell 2's cross-section. This design ensures that the entire hanger occupies virtually no space within the auger shell 2, does not obstruct material flow, and avoids material blockage. Furthermore, the hanger is fixed at two points, resulting in better overall structural stability.

[0031] The suspension system of this invention is spaced along the entire auger shaft 3. Through the cooperation between the hanger and the vertical clamping frame, the entire auger shaft 3, in addition to its two ends, has other support and suspension points. This prevents the auger shaft 3 from sagging due to long-term use, avoids contact and wear between the auger blades 5 on the auger shaft 3 and the inner wall of the auger housing 2, and extends the service life of the auger. Furthermore, the suspension system is fixed to the auger housing 2 at two points, making the overall structure more stable. Since the various components of the suspension system are connected by bolts 9 and nuts 11, the installation and disassembly of the suspension system are simpler and more convenient.

[0032] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed herein, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
