Description

Technical Field

[0001] The invention relates to a rear-mounted spreader with a spreading structure capable of continuous lifting and lowering driving, belonging to the technical field of snow removal and spreading equipment. Background Art

[0002] The spreader is one of the key components of snow removal equipment for highways and urban roads. Its main function is to spread the snow-melting agent evenly on the road surface. The existing spreaders on the market still have shortcomings. First, when the spreading width of the snow-melting agent needs to be increased or reduced, the existing snow-removing spreader can only be adjusted by manually removing the bolts and manually lifting the spreading structure to adjust its height above the ground, and the height above the ground can only be adjusted in steps. Second, in the existing spreader, the spreading motor is installed directly below the spreading plate. When the spreader is working, the snow-melting agent is very easy to contact the spreading motor and corrode the motor housing. Third, when the spreading equipment completes the work and the excess snow-melting agent is unloaded from the silo, the existing spreader can only be tilted by manually pushing and pulling backwards. Fourth, the spreading funnel plate in the existing spreader is not made of anti-corrosion material. When the spreader is working, the snow-melting agent contacts the spreading funnel plate and easily causes corrosion of the plate. Therefore, it is particularly important to develop a spreader that can adjust the ground clearance of the spreading structure more quickly, quickly empty the remaining material, and protect the driving motor housing from corrosion. Summary of the invention

[0003] In order to solve the problem that the existing spreader needs manual lifting of the spreading structure to adjust the ground clearance and manual pushing and pulling of the spreader to realize the emptying of residual material, the present invention provides a spreader with a spreading structure that can realize continuous lifting and driving. It can not only quickly adjust the ground clearance of the spreading structure and quickly realize the emptying of residual material, but also take anti-corrosion measures for the spreading motor.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0005] A spreading structure can be continuously lifted and lowered to drive a rear-mounted spreader, comprising a housing, a flipping and unloading mechanism, a lifting mechanism, a spreading structure and a driving device;

[0006] The housing is arranged at the lower part of the transmission roller group of the spreader;

[0007] The lifting mechanism is symmetrically arranged on both sides of the shell near the lower part;

[0008] The spreading structure is arranged on the lifting mechanisms on both sides of the shell;

[0009] One end of the overturning unloading mechanism is arranged on the spreading structure, and the other end is arranged on the chassis of the vehicle;

[0010] The driving device is arranged at the rear side of the spreading structure and close to the rear part of the chassis of the spreader.

[0011] The spreading structure can continuously lift and lower to drive the rear-mounted spreader, and the lifting mechanism includes a guide rail slider assembly, a connecting beam, a guide shaft and a lead screw nut assembly;

[0012] The guide rail and slider assembly is formed between the connecting beam and the housing, and includes a guide rail and a slider. The guide rail is fixed on the housing, and the slider is slidably matched with the guide rail.

[0013] The screw nut assembly includes a screw and a nut. The nut cooperates with the screw. The screw is arranged on the housing via a screw fixing seat. A hand wheel is arranged on the upper end of the screw. The hand wheel is fixed to the screw through a connecting nut.

[0014] The guide groove is arranged on the housing;

[0015] The guide shaft is arranged on the connecting beam and is driven by a hand wheel to slide along the guide groove.

[0016] The spreading structure can continuously lift and lower the rear-mounted spreader, wherein a limit plate is arranged on the lead screw, a reinforcing plate is arranged above the lead screw fixing seat, and the reinforcing plate is arranged on the housing.

[0017] The spreading structure can continuously lift and lower a rear-mounted spreader, wherein the guide groove is formed between two angle steels, and the angle steels are arranged on the housing.

[0018] The spreading structure can continuously lift and lower the rear-mounted spreader, and the driving device includes a driving motor, two pulleys and a conveyor belt. The driving motor is provided with a driving protective cover, and the two pulleys and the conveyor belt are provided with a conveyor belt protective cover.

[0019] The spreading structure can continuously lift and lower to drive the rear spreader. The tipping unloading mechanism includes a cylinder and a unloading dustpan. The cylinder piston rod is hinged to the spreading structure. The cylinder barrel is fixed to the rear of the vehicle chassis. The unloading dustpan is detachable.

[0020] Placed on the housing.

[0021] The spreading structure can be continuously lifted and lowered to drive the rear-mounted spreader, and the funnel plates in the spreading structure are all made of corrosion-resistant metal materials.

[0022] The advantages of the present invention are:

[0023] 1. Lifting mechanisms are arranged on both sides of the shell, and the lifting mechanisms are connected to the upper end of the spreading structure, so that the ground clearance of the spreading structure is adjusted from the original step-by-step adjustment to a continuous adjustment, which improves work efficiency and reduces labor intensity.

[0024] 2. The drive device is arranged at the rear side of the spreading structure close to the rear part of the vehicle chassis, and a protective cover is arranged above the drive device, which solves the problem that the motor in the drive device is easily corroded by the snow melting agent when the existing spreader is in operation.

[0025] 3. An oil cylinder is set at the rear of the spreader. When the excess snow melting agent is unloaded, the oil cylinder pulls the spreader backward to rotate and tilt the spreader. After the oil cylinder stops, the unloading dustpan is manually installed on the upper end surface of the shell to complete the unloading. The setting of the oil cylinder solves the problem that the existing spreader can only be rotated and tilted by manual pushing and pulling.

[0026] 4. The funnel of the spreading structure is made of anti-corrosion metal material, which not only increases the service life of the spreader but also saves material costs. BRIEF DESCRIPTION OF THE DRAWINGS
