Description

Technical Field

[0001] The utility model belongs to the technical field of material unloading devices for vehicles, especially an automatic auxiliary material unloading system for vehicles. Background Art

[0002] Transport vehicles are generally divided into hopper-type transport vehicles and container-type transport vehicles. For hopper-type transport vehicles, their goods are loaded from above. To ensure the carrying capacity, the hoppers are generally filled relatively full. Some hopper-type transport vehicles also have heightening structures above the hoppers, that is, struts are added at the four corners of the hopper, and a tarpaulin is arranged around the outer circle of the struts, so that the materials can be filled up to the position of the heightening structure.

[0003] However, too much filled material will compact the material in the hopper, resulting in the inability to unload the material after opening the vehicle door. For example, sheet materials such as bagasse, reeds, trees, wheat straws, and bamboo used for papermaking will become dense due to gradual sinking during transportation vibration, and the filling height of the whole material is greater than the height of the vehicle door, which will lead to the problem of inability to unload the material after opening the vehicle door. Moreover, in winter, the material will be frozen, and there will also be problems with difficult unloading.

[0004] The existing method is to manually hold a stick and stand at the rear side of the hopper to poke the material. This not only has problems such as high labor intensity and low unloading efficiency, but also has potential safety hazards of dust inhalation and workers falling into the unloading pit.

A Y-axis fixed beam is installed on the X-axis servo translation mechanism, and a Z-axis servo lifting mechanism is installed on the Y-axis fixed beam. A material poking mechanism is driven and installed at the bottom of the Z-axis servo lifting mechanism.

[0027] The material poking mechanism includes a material poking mounting table 22, a reduction motor 23 and a spiral material breaker 21. A material poking mounting table is installed at the bottom of the Z-axis servo lifting mechanism. Spiral material breakers driven by a reduction motor are arranged at intervals on the material poking mounting table. The spiral material breaker has a structure in which spiral blades with a pitch of 200 mm are arranged on the rod body.

[0028] The present utility model is installed at the upper end of the discharge pit 9, and the columns on both sides are installed on the concrete foundation 8 on the ground.

[0029] During use, the door of the transport vehicle on the horizontally placed flap is opened, and then the motor drives the flap to rotate and lift, so that the transport vehicle is in an inclined state. Then the X-axis servo translation mechanism drives the Z-axis servo lifting mechanism to move horizontally until it moves to a position near the inside of the door. Subsequently, the Z-axis servo lifting mechanism drives the material poking mechanism to descend. At the same time, the spiral material breaker on the material poking mechanism rotates forward and descends and rotates in reverse to break the material, so as to achieve the purpose of auxiliary discharging of the transport vehicle.

The two X-axis gears are engaged with the X-axis rack located on the side of the X-axis mounting cross beam.

[0031] Under the action of the X-axis servo motor with a speed reducer, the Y-axis fixed cross beam is driven to achieve horizontal movement in the X-axis direction on the X-axis mounting cross beam, so as to meet the discharging requirements for transport vehicles of different lengths.

A Z-axis rack is installed on one side of the Z-axis lifting beam. A Z-axis gear driven by the Z-axis servo motor with a speed reducer is meshed on the Z-axis rack.

[0033] Under the action of the Z-axis servo motor with a speed reducer, the Z-axis lifting beam is driven to lift up and down on the Y-axis fixed beam.

[0035] During use, the position of the sliding block on the Z-axis guide rail can be adjusted according to the depth that the spiral material breaker needs to extend into the material, so as to achieve the adjustment of the descending height of the spiral material breaker.

[0036] For the convenience of repairing the device, a maintenance ladder 7 and a maintenance corridor 5 are further included. The maintenance corridor is installed on the columns at the rear end and the left and right ends of the material poking mechanism, and a maintenance ladder is arranged on one side of the maintenance corridor.
