Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to a grain dryer convenient for maintenance. Background Technique

[0002] China is a major grain-producing country, and grain dryers are commonly used grain storage equipment. Existing grain dryers include: the silo of the dryer, the upper auger, elevator, lower auger, and grain feeding structure installed on the silo. Inside the silo, a tempering bin, a drying bin, and a recycling bin are arranged in sequence from top to bottom. During drying, the grain conveying equipment puts the grain into the hopper of the elevator. Through the elevator, the grain is lifted to the top of the silo, and the upper auger sends the grain from the grain inlet at the top of the silo into the silo. The grain first falls from the grain inlet into the tempering bin. Under the action of its own weight, the grain in the tempering bin slowly moves from top to bottom to the drying bin, and the grain is heated and dried by hot air in the drying bin. The dried grain passes through the recycling bin for buffering and recycling from the bottom of the drying bin, and then is sent into the funnel-shaped grain hopper through the grain feeding structure. The bottom of the grain hopper is the feeding port of the lower auger, and the grain is discharged from the grain hopper into the lower auger. The lower auger conveys the grain into the elevator and then into the upper auger, and so on, drying the grain multiple times to make the grain fully dried.

[0003] Among them, the grain feeding structure rotates by the roller shaft driven externally, and the roller shaft is supported by a bearing sleeve. The existing bearing sleeve is generally relatively tightly sleeved on the side position of the roller shaft. When the bearing sleeve is damaged, it is necessary for workers to climb to the corresponding position manually and disassemble it with a variety of tools. However, due to limited space and a large number of tools to carry, the maintenance is difficult and inconvenient. Therefore, we propose a grain dryer convenient for maintenance. Content of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a grain dryer convenient for maintenance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme. A grain dryer convenient for maintenance includes a recycling bin assembly. Inside the recycling bin assembly, there is a grain feeding assembly capable of feeding grain. The grain feeding assembly includes a grain feeding roller shaft. On the side of the grain feeding roller shaft, there is a movable movable rod. On the side of the movable rod, there is a movable extrusion block. On the side of the grain feeding roller shaft, there is a telescopic movable block.

[0006] Preferably, the recycling bin assembly includes a silo. Inside the silo, first guiding plates are fixedly installed equidistantly. Corresponding to the first guiding plates inside the silo, second guiding plates are fixedly installed equidistantly in a mirror image manner, and the second guiding plates at the relative positions are connected together.

[0007] Preferably, the bin body is a hollow rectangular bin, the first guiding plate is an "L"-shaped rectangular plate, and the second guiding plate is an "L"-shaped rectangular plate.

[0008] Preferably, the grain feeding assembly includes connecting plates fixedly installed at equal intervals and in a mirror image manner on the lower side of the second guiding plate. The grain feeding roller shaft is arranged inside the bin body. An installation plate is fixedly installed on the outer side of the bin body. A bearing structure is arranged on the upper side of the installation plate. An observation block is arranged on the outer side of the bin body. Installation grooves are formed on both sides of the circular shaft of the grain feeding roller shaft. A movable rod is movably installed inside the installation grooves. A pressing block is fixedly sleeved on the side surface of the movable rod. Activity grooves are circumferentially and arrayedly formed on the inner wall of the installation grooves. A connecting cylinder is fixedly connected between the side surface of the pressing block and the inner wall of the installation grooves. A movable block is movably installed inside the activity grooves. A return spring is fixedly connected between the side surface of the movable block and the inner wall of the activity grooves.

[0009] Preferably, the observation block is a rectangular block made of glass. The installation groove is a cylindrical groove with a convex cross-section. The movable rod is a cylindrical rod with a cross-section in the shape of a cross. The pressing block is a circular ring block with a trapezoidal cross-section. The activity groove is a cylindrical groove with a cross-section in the shape of a cross. The connecting cylinder is a cylindrical barrel made of spring steel with a cross-section in the shape of a continuous "W". The movable block is a cylindrical block with a cross-section in the shape of a cross.

[0012] The utility model provides a grain dryer convenient for maintenance, having the following beneficial effects:

[0013] (1) For the grain dryer facilitating maintenance, through the cooperation of internal components of the grain feeding assembly, when pressing the movable rod to slide inside the installation groove, the movable rod drives the extrusion block to deform the connecting cylinder. At the same time, as the extrusion block moves with the movable rod, it no longer fits against the side of the movable block. Under the deformation force of the reset spring, the movable block supports it to slide inside the movable groove, and the movable block slides into the installation groove. In this way, when removing the screws of the bearing structure, the bearing sleeve can be directly detached from the circular shaft side of the grain feeding roller shaft. After replacing the new bearing structure and loosening the movable rod, under the deformation of the connecting cylinder, the support extrusion block is reset and extruded against the side of the movable block, so that the movable block is extruded against the bearing sleeve of the bearing structure and the cylindrical side of the grain feeding roller shaft to play a certain fixing role. In this way, the bearing sleeve can be quickly replaced and does not require many tools, and it is also convenient for personnel to carry and use.

[0014] (2) For the grain dryer facilitating maintenance, through the cooperation of internal components of the grain feeding assembly, when pressing the movable rod, remove the observation block and fix the cylindrical shaft of the grain feeding roller with tools, and rotate the circular shaft of the grain feeding roller. The circular shaft of the grain feeding roller is threadedly engaged with the fitting block. The fitting block slides inside the fitting groove, and the synchronous restraint block slides in cooperation inside the restraint groove. Driven by the connecting rod, the grain feeding plate slides inside the connecting groove to adjust the position. After loosening the movable rod, the adjustment is completed. In this way, the grain feeding plate can be adjusted for use to match different grains and reduce the grain breakage rate. Description of the Drawings
