Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain warehouse cleaning equipment, in particular to a hydraulic clutch of a spiral warehouse cleaning machine. Background Art
[0002] The spiral silo cleaner is one of the main equipment for grain silo cleaning operations. When the material is severely compacted, a large area of the material will collapse during the cleaning process, which will cause the auger shaft of the spiral silo cleaner to be completely buried by the material.
[0003] The existing spiral bin clearing machine uses a pneumatic clutch to connect two auger shafts. The pneumatic clutch uses air power to drive the driven tooth plate to press against the active tooth plate so that it is in a power output state; when the air pressure is released, the elastic component between the driven tooth plate and the active tooth plate drives the driven tooth plate to move axially away from the active tooth plate, thereby switching to a power cut-off state. The defects and shortcomings of the traditional pneumatic clutch are: when the auger shaft is completely buried by grain materials, the materials will fill the spiral space of the auger shaft, and then exert a large axial parallel pressure on the spiral blades on the auger shaft, which will make it difficult for the pneumatic clutch to switch smoothly between the power output state and the power cut-off state.
[0004] Therefore, there is an urgent need to provide a hydraulic clutch for a spiral bin cleaning machine with large load and stable operation. Utility Model Content

DETAILED DESCRIPTION
[0033] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0034] Reference Figure 1 and Figure 2 The present embodiment provides a hydraulic clutch of a spiral bin clearing machine, including an input shaft 1, an output shaft 2, a protective housing assembly 3, a driving toothed disc 4, a driven toothed disc 5 and a hydraulic drive assembly 6.
[0035] A driving toothed disc 4 and a driven toothed disc 5 are arranged inside the protective housing assembly 3, and teeth for meshing are arranged circumferentially on opposite sides of the driving toothed disc 4 and the driven toothed disc 5; after one end of the input shaft 1 extends into the protective housing assembly 3, it is drivingly connected to the driving toothed disc 4; one end of the output shaft 2 extends into the protective housing assembly 3, and the driven toothed disc 5 is circumferentially limited on the output shaft 2;
[0036] A hydraulic drive assembly 6 is fixedly mounted on the protective housing assembly 3, and a driving connection is formed between the output end of the hydraulic drive assembly 6 and the driven sprocket 5, so as to drive the driven sprocket 5 to approach or move away from the driving sprocket 4 along the axial direction of the output shaft 2, thereby switching the hydraulic clutch between a power output state and a power cut-off state.
[0037] Furthermore, the hydraulic drive assembly 6 includes a hydraulic cylinder 7, a piston component 8 and a first bearing 11. The hydraulic cylinder 7 is fixedly mounted on the protective housing assembly 3, the piston component 8 is slidably disposed inside the hydraulic cylinder 7, but its output end extends to the outside of the hydraulic cylinder 7; the outer ring of the first bearing 11 is fixedly connected to the output end of the piston component 8, and the inner ring of the first bearing 11 is fixedly sleeved on the driven chainring 5.
[0038] Furthermore, the hydraulic cylinder body 7 and the output shaft 2 are rotatably connected via a second bearing 12 .
[0039] Furthermore, the hydraulic cylinder body 7 is provided with a first hydraulic oil interface 9 and a second hydraulic oil interface 10 which are in communication with the internal chamber, and the first hydraulic oil interface 9 and the second hydraulic oil interface 10 are in communication with an external hydraulic oil pipeline.
[0040] like Figure 2 As shown, when the first hydraulic oil interface 9 is fed with oil and the second hydraulic oil interface 10 is fed with oil, the piston component 8 moves to the left and drives the driven chainring 5 to move to the left to engage with the active chainring 4. When the second hydraulic oil interface 10 is fed with oil and the first hydraulic oil interface 9 is fed with oil, the piston component 8 moves to the right and drives the first bearing 11 and the driven chainring 5 to move to the right, so that the driven chainring 5 is separated from the active chainring 4.
[0041] The hydraulic clutch of the utility model adopts hydraulic power, which transmits large torque and can also bear large loads. Therefore, it can stably switch between the power output state and the power cut-off state when the spiral blade is subjected to large positive pressure, and will not be stopped by grain materials.
[0042] See also Figure 3 The hydraulic clutch further comprises a connecting sleeve 13 and an intermediate sleeve 14. The connecting sleeve 13 is welded on the input shaft 1, and the connecting sleeve 13, the intermediate sleeve 14 and the active toothed disc 4 are coaxial and arranged along the axis and are fixedly connected together by bolts.
[0043] Furthermore, a flat key is provided on the circumferential surface of the output shaft 2, which limits the circumferential position of the driven sprocket 5 on the output shaft 2; the interior of the active sprocket 4 is rotatably connected to the output shaft 2 through the third bearing 15, and a shaft end baffle 16 is installed on the left end face of the output shaft 2 for axial positioning of the third bearing 15.
[0044] During operation, the rotation of the input shaft 1 drives the connecting sleeve 13 , the intermediate sleeve 14 and the active chainring 4 to rotate synchronously; the rotation of the driven chainring 5 drives the output shaft 2 to rotate together, but the driven chainring 5 can also move along the axial direction of the output shaft 2 .
[0045] In this embodiment, the protective housing assembly 3 includes a protective sleeve 17, a flange and a fixing plate 20. The protective sleeve 17 is provided with openings at both ends, one end of which is bolted to the flange, and a first through hole for the input shaft 1 to pass through is provided on the flange; the other end of the protective sleeve 17 is bolted to the fixing plate 20, and a second through hole for the output shaft 2 to pass through is provided on the fixing plate 20.
[0046] Furthermore, a first dustproof seal ring is provided at the first through hole, and a second dustproof seal ring is provided at the second through hole. The purpose of providing the dustproof seal ring is to prevent external dust from entering the interior of the protective housing assembly 3 and wearing the transmission components inside the hydraulic clutch.
[0047] Preferably, the flange is a first split flange 18 and a second split flange 19, and the split lines of the first split flange 18 and the second split flange 19 are staggered during installation. The purpose of such a setting is to facilitate installation and disassembly, and at the same time prevent dust from entering the protective sleeve 17. Specifically, since the end of the input shaft 1 is welded with a connecting sleeve 13, the installation and disassembly of the integrated flange is inconvenient. The first split flange 18 and the second split flange 19 of this embodiment are split flanges, and the flange body of the split flange is divided into two halves or more parts along the circumferential direction, which is convenient for installation or disassembly. However, the split flange has a radial docking split line, and dust can easily enter the protective sleeve 17 from the gap at the split line. In order to solve the above problems, this embodiment adopts two split flanges, and the split lines of the two are staggered during installation, thereby preventing dust from entering the interior of the protective housing assembly 3 through the split line.

The protective housing assembly 3 of the hydraulic clutch is fixedly arranged on the body support device 21, the input shaft 1 of the hydraulic clutch is connected to the first auger shaft 22, and the output shaft 2 of the hydraulic clutch is connected to the second auger shaft 23.
