Description

Technical Field

[0001] The utility model belongs to a material conveying and transporting machine, and mainly relates to a horizontal double-auger material conveying and lifting mechanism. Background Art

[0002] At present, when the material conveying and lifting mechanism composed of two horizontal conveying auger assemblies and one vertical lifting auger assembly starts and stops the conveying and lifting operation, a total of three auger assemblies are started or stopped synchronously. In many years of production operation practice, it is found that every time the material conveying and lifting operation stops, since all three auger assemblies stop rotating synchronously, a large amount of material that has not been lifted and discharged is always retained in the vertical lifting auger assembly used for material lifting operations. When the equipment is started again for material conveying and lifting operations, the retained material will not only make the vertical lifting auger assembly difficult and laborious to start, greatly increase power consumption, and reduce the efficiency of conveying and lifting operations, but may even cause mechanical equipment failure or damage, thereby increasing operating costs. Summary of the Invention

[0003] The purpose of this utility model is to address the problems existing in the above-mentioned existing technologies, combine with the current actual needs for material conveying and lifting operations, and develop and design a horizontal double-auger material conveying and lifting mechanism with a new structure, so as to achieve the purpose of smooth and convenient starting of the vertical lifting auger assembly, reduce starting power consumption, ensure the operating efficiency of the mechanism, and avoid equipment failure.

[0004] The basic design of the present invention is as follows: a fixed bidirectional hydraulic oil cylinder is vertically arranged at the outer side of the vertical lifting auger assembly on the material box, a push-pull rod is installed at the lower end portion of the cylinder rod of the bidirectional hydraulic oil cylinder and is perpendicular to the horizontal conveying auger assembly, and two pin shafts are axially positioned and radially reciprocatingly inserted into the long through holes on both sides of the push-pull rod; a coaxial tooth clutch assembly is installed respectively on the outer side of the material box and at both sides below the push-pull rod using two seat plates, the structure of the coaxial tooth clutch assembly is as follows: a drive shaft is installed on the seat plate for axial and radial positioning and circumferential rotation, a sprocket A is fixed on one end portion of the drive shaft, an active end face tooth wheel is circumferentially and radially positioned and axially movably sleeved on the other end portion of the drive shaft, a pressure spring is sleeved on the drive shaft, and one end of the pressure spring is axially positioned on the drive shaft The clutch control fixed end face cam is axially and radially positioned, and can be circumferentially rotatable relative to each other, and the clutch control dynamic end face cam is fitted on the outer side of the active end face dynamic end face cam, and the clutch driving plate is fixedly mounted on the outer end surface of the clutch control dynamic end face cam, and the driven end face dynamic end face gear is fixedly mounted on the outer end of the horizontal conveying auger assembly, and the inner end portion of the driving shaft is rotatably supported and inserted into the center hole of the driven end face dynamic end face gear. The clutch control fixed end face cam is axially and radially positioned, and can be circumferentially rotatable relative to each other, and is fitted on the outer side of the driven end face dynamic end face gear. The clutch control fixed end face cam and the driven end face dynamic end face gear are respectively inserted and locked or disengaged from the insertion and locking cooperation with the clutch control dynamic end face cam and the active end face dynamic end face gear; the clutch driving plate is radially positioned, circumferentially rotatable, and axially movably fitted on the pin shaft, thereby forming a horizontal double auger material conveying and lifting mechanism.

[0005] The utility model adopts a structure in which a coaxial tooth clutch is installed between the two horizontal conveying auger assemblies and the drive shaft, thereby realizing separate control of the operating power transmission or the stopping power transmission of the two horizontal conveying auger assemblies and the vertical lifting auger assembly. When the horizontal conveying auger assembly stops rotating for conveying operation, the vertical lifting auger assembly can continue to rotate, and stops rotating after the material retained therein is lifted and cleaned, thereby providing good conditions for the next conveying operation. The utility model has the characteristics of novel, unique and simple structure, easy and convenient regulation, low power consumption for operation startup, smooth startup and operation, high operating efficiency, reliable use and few faults.

[0012] The following is a detailed description of the implementation scheme of the utility model in conjunction with the accompanying drawings. A horizontal double-auger material conveying and lifting mechanism includes a material box 1, two horizontal conveying auger assemblies 13 are installed parallel to each other and rotatably above the bottom plate inside the material box 1, a vertical lifting auger assembly 2 is installed at the inner position of the box on one side of the material box 1, the feeding end of the lower end of the vertical lifting auger assembly 2 is connected to the discharge end of the two horizontal conveying auger assemblies 13, a reversing gear box 12 is fixed on the outer side of the lower side of the bottom plate of the material box 1, the power output shaft of the reversing gear box 12 is connected to the vertical lifting auger assembly 2, a sprocket B9 is fixed on the power input shaft 10 of the reversing gear box 12, and the reversing gear box 12 is connected to the vertical lifting auger assembly 2. A fixed bidirectional hydraulic cylinder 3 is vertically arranged on the outer side of the vertical lifting auger assembly 2 on the box 1, and a push-pull rod 4 is installed perpendicularly to the horizontal transport auger assembly 13 on the lower end of the cylinder rod of the bidirectional hydraulic cylinder 3. Two pins 5 are axially positioned and radially reciprocatingly inserted into the long through holes on both sides of the push-pull rod 4; on the outer side of the material box 1, at both sides below the push-pull rod 4, two base plates 11 are used to install a coaxial tooth clutch assembly 8. The structure of the coaxial tooth clutch assembly 8 is: a driving pin is installed on the base plate 11 for axial and radial positioning and circumferential rotation. The shaft 7 and the sprocket A6 are fixed on the end of one side of the driving shaft 7, the active end face toothed wheel 8-3 is positioned circumferentially and radially and is axially movable on the other end of the driving shaft 7, and the pressure spring 8-1 is set on the driving shaft 7. One end of the pressure spring 8-1 is axially positioned on the driving shaft 7, and the other end of the pressure spring 8-1 is in extrusion contact with the active end face toothed wheel 8-3. The clutch control dynamic end face cam 8-2 is axially and radially positioned on the outside of the active end face toothed wheel 8-3 and can be relatively rotated in the circumferential direction. The clutch drive plate 8-6 is fixed on the outer end surface of the clutch control dynamic end face cam 8-2, and is fixed on the horizontal direction. The driven end face spline wheel 8-4 is fixedly mounted on the outer end of the transport auger assembly 13, and the inner end of the drive shaft 7 is rotatably supported and inserted into the center hole of the driven end face spline wheel 8-4. The clutch control fixed end face cam 8-5 is axially and radially positioned and circumferentially rotatable on the outside of the driven end face spline wheel 8-4. The clutch control fixed end face cam 8-5 and the driven end face spline wheel 8-4 are respectively inserted and locked with or disengaged from the insertion and locking fit with the clutch control movable end face cam 8-2 and the active end face spline wheel 8-3; the clutch drive plate 8-6 is radially positioned, circumferentially rotatable, and axially movably fitted on the pin shaft 5.

[0013] During operation, the material is filled in the material box 1 and covers the two horizontal conveying auger assemblies 13. The external rotational power is synchronously driven by the sprocket A6 and the sprocket B9 to rotate the two horizontal conveying auger assemblies 13 and the vertical lifting auger assembly 2 respectively. The two horizontal conveying auger assemblies 13 push the material in the material box 1 from the discharge end to the inlet at the lower end of the vertical lifting auger assembly 2, and the material is lifted and discharged by the vertical lifting auger assembly 2 to complete the transportation and lifting operation. When the material transporting and lifting operation is to be ended, the two-way hydraulic cylinder 3 is first started to extend its cylinder rod downward, and the clutch control dynamic end face cam 8-2 is driven to rotate on the driving shaft 7 through the push-pull rod 4, the pin shaft 5, and the clutch drive plate 8-6.

At this time, the vertical lifting auger assembly 2 that is still rotating continues to lift and transport the stored materials until they are emptied, and then stops the input of external power, creating conditions for starting the material transporting and lifting operation next time. Retract the cylinder rod of the bidirectional hydraulic cylinder 3 upward. Under the thrust of the pressure spring 8-1, the clutch drive plate 8-6, the clutch control dynamic end face cam 8-2 and the active end face toothed wheel 8-3 complete the axial return movement on the drive shaft 7, so that the active end face toothed wheel 8-3 and the driven end face toothed wheel 8-4 are inserted and engaged.
