Description

Technical Field

[0001] This utility model belongs to the field of grain machinery technology, and specifically relates to a bulk material lifting device based on spiral material collection. Background Technology

[0002] Grain warehouses are the most important grain storage facilities. During the processes of grain transfer, leveling, and clearing, the structural characteristics and operational content of grain warehouses, which are large in volume and height and are enclosed environments, pose unique technical challenges because grain is in bulk.

[0003] Existing manual operations suffer from problems such as long processing times, harsh working conditions, low efficiency, high labor intensity, and significant health and safety concerns, facing multiple technical bottlenecks: In terms of efficiency, workers must perform heavy shoveling, leveling, or cleaning operations within confined spaces, which is extremely time-consuming and discontinuous; in terms of working conditions, the dust concentration inside the silo is extremely high (potentially causing explosions and respiratory illnesses), there is a risk of oxygen deficiency, insufficient lighting, and the hazard of falls from heights or suffocation from being trapped in fluidized grain piles; in terms of intensity, continuous heavy physical labor far exceeds the limits of human endurance. Therefore, the leveling, cleaning, and transfer of grain in silos urgently require mechanization and automation to effectively improve operational efficiency and reduce labor intensity. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a bulk material lifting device based on a spiral material collection system. This device uses spiral blades to push grain from both sides of the bucket to the center of the bucket, and then uses a shovel to move the grain particles onto a belt conveyor, thereby achieving rapid lifting of the grain particles inside the bucket.

[0005] The technical solution of this utility model is as follows: a bulk material lifting device based on spiral material collection, characterized in that: it includes a spiral drive mechanism, spiral blades, a lever, a bucket, a belt conveyor, a belt driver, and a cover. The spiral drive mechanism is installed on the top of the bucket, and the spiral drive mechanism is rotatably connected to a spiral blade shaft. The spiral blade shaft is located inside the bucket, and spiral blades are provided on the outside of the spiral blade shaft. A lever is provided on the spiral blade shaft directly opposite the belt of the belt conveyor. The belt driver and the belt conveyor are provided with a cover on their outer sides. The belt driver is used to drive the belt conveyor to move.

[0006] The helical transmission mechanism includes a transmission reduction motor and a transmission belt, which is either a belt or a chain, and is connected to the helical blade shaft.

[0007] The belt drive includes a drive geared motor and a drive roller, with a drive belt sleeved on the outside of the drive roller.

[0008] The belt conveyor includes a conveyor belt, with several idlers distributed on the lower side of the conveyor belt and an upper pressure roller on the upper side of the conveyor belt.

[0009] The spiral blade shaft is set perpendicular to the belt transmission direction of the belt conveyor.

[0010] The technical effect of this utility model is as follows: This utility model uses spiral blades to push the grain on both sides of the bucket to the center of the bucket, and uses a paddle to push the grain particles to the belt conveyor. The belt conveyor lifts the bulk material in the grain bin to the silo or other equipment, thereby realizing the rapid lifting of grain particles in the bucket.

[0011] The following will provide further explanation in conjunction with the accompanying drawings. Attached Figure Description
