Description

Technical Field

[0001] This utility model relates to the field of sanitation transport dump vehicles, and in particular to a front and rear double-force conveying roller device for sanitation transport dump vehicles. Background Technology

[0002] Currently, sanitation transport vehicles use a horizontal unloading carriage. A conveyor belt is installed on the bottom of the horizontal unloading carriage. The existing carriage has a single conveyor roller at the front as the power unit. The front conveyor roller drives the chain, pulling the conveyor belt to the rear outlet for unloading. However, during long-term use, the heavy-duty conveyor belt transmits significant friction with the carriage floor. The power of the single conveyor roller at the front of the carriage is relatively weak, leading to frequent occurrences of motor overheating, burning, and damage. This makes it impossible to drive the conveyor belt to operate and unload, affecting the normal use of the horizontal unloading vehicle. In view of the above reasons, a front and rear double-force conveyor roller device for sanitation transport dump vehicles is proposed. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that a single conveyor roller installed at the front of the horizontal unloading compartment of a sanitation transport vehicle causes overload operation and motor damage when driving a heavy-duty conveyor belt, thus failing to meet the requirements for unloading materials. Through reasonable design, this invention provides a front and rear double-force conveyor roller device for sanitation transport dump vehicles. This invention installs a pair of conveyor rollers at both ends of the dump vehicle's floor. Each pair of conveyor rollers is a front and rear double-force combination, with hydraulic motors installed in the middle of each roller. The powerful hydraulic motors of the double conveyor rollers can easily drive the conveyor belt for unloading, avoiding the overload operation of a single conveyor roller driving a heavy-duty conveyor belt or causing motor overheating and damage, thus ensuring the normal operation of the horizontal unloading vehicle.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A front and rear double-force conveyor roller device for sanitation transport dump vehicles, comprising: a truck bed 1, a rear conveyor belt roller 2, a rear sprocket 2-1, a rear conveyor belt pulley 2-2, a rear axle seat 2-3, a front conveyor belt roller 3, a front sprocket 3-1, a front conveyor belt pulley 3-2, a front axle seat 3-3, a rear hydraulic motor 4, a front hydraulic motor 5, a conveyor belt 6, a transmission chain 7, and a pusher plate device 8; a truck bed 1 is provided at the bottom of the truck bed, and a pair of conveyor belt rollers are provided at both ends of the truck bed 1, the pair of conveyor belt rollers being respectively configured as: a front conveyor belt roller 3 and a rear conveyor belt roller 2; the front of the truck bed 1... A front conveyor belt roller 3 is installed at one end, and a rear conveyor belt roller 2 is installed at the rear end of the carriage floor 1. A pair of front axle seats 3-3 are installed between the two ends of the front conveyor belt roller 3 and the front end of the carriage floor 1, and a pair of rear axle seats 2-3 are installed between the two ends of the rear conveyor belt roller 2 and the rear end of the carriage floor 1. A front hydraulic motor 5 is installed in the middle of the front conveyor belt roller 3, and a support seat is installed between the front hydraulic motor 5 and the middle of the front end of the carriage floor 1. A rear hydraulic motor 4 is installed in the middle of the rear conveyor belt roller 2, and a support seat is installed between the rear hydraulic motor 4 and the middle of the rear end of the carriage floor 1. The front hydraulic motor 5 and the rear hydraulic motor 4 are configured as a pair of synchronous hydraulic motors, and the pair of synchronous hydraulic motors are used for a pair of conveyor belt rollers.

[0005] The front conveyor belt roller 3 has three pairs of front conveyor belt pulleys 3-2 in the middle and on both sides, and front sprockets 3-1 are set on both sides of each pair of front conveyor belt pulleys 3-2; the rear conveyor belt roller 2 has three pairs of rear conveyor belt pulleys 2-2 in the middle and on both sides, and rear sprockets 2-1 are set on both sides of each pair of rear conveyor belt pulleys 2-2; the three pairs of front conveyor belt pulleys 3-2 are respectively set to correspond to the three pairs of rear conveyor belt pulleys 2-2, and a conveyor belt 6 is set between the front conveyor belt pulleys 3-2 and the rear conveyor belt pulleys 2-2; the rear sprockets 2-1 and the front sprockets 3-1 are set to four pairs of sprockets, and a transmission chain 7 is set around each of the opposite sprockets.

[0006] Beneficial effects: This utility model installs a pair of conveyor rollers at both ends of the bottom plate of the dump truck. The pair of conveyor rollers is a combination of front and rear double force. Hydraulic motors are installed in the middle of the two conveyor rollers. The pair of hydraulic motors of the two conveyor rollers are powerful and can easily drive the conveyor belt to run and unload materials. This avoids the overload operation of a single conveyor belt roller driving a heavy-duty conveyor belt or causing the motor to overheat and break down, thus ensuring the normal use of the horizontal unloading vehicle.
