Description

Technical Field

[0001] The utility model relates to a shovel lifting machine. Background Art

[0002] Traditionally, waste floor removal has been largely manual. Hard materials like tiles and wood floors require breaking them up before being manually pried and removed. Soft materials adhered to the foundation, such as PVC flooring, rubber flooring, carpet, and elastic coatings, require manual removal with a spatula. Manual removal is not only labor-intensive and inefficient, but also expensive, incomplete, and difficult to implement on a large scale.

[0003] Application number: CN201820765549.3 The utility model relates to a floor cleaning device, which includes a forklift (100) and a standard chassis (200), wherein a cleaning joint (300) is encapsulated in the standard chassis (200), and a working end of the cleaning joint (300) extends out of the bottom of the standard chassis (200) for cleaning the ground. The cleaning joint (300) is divided into a grinding joint, a polishing joint, a dust removal joint, a scraping joint, a milling joint, a chiseling joint, and a cleaning joint according to the cleaning type; when working, the forklift (100) serves as a driving device of the cleaning device to fork the corresponding standard chassis (200) to achieve grinding, polishing, dust removal, scraping, milling, chiseling, and cleaning of the ground. However, the floor cleaning device recorded in the above patent technology does not scrape the ground thoroughly in actual use, and the scraping effect is not ideal. Utility Model Content

[0012] The traveling mechanism is arranged on the vehicle frame, and the traveling mechanism comprises a speed regulating motor and two driving wheels, wherein the speed regulating motor is fixedly mounted on the vehicle frame, and the speed regulating motor drives the two driving wheels to move;

[0013] The rotating assembly includes a high-speed motor, which is fixedly connected to the vehicle frame;

[0014] The shovel assembly includes a movable plate, a crankshaft, a shovel blade and several elastic columns. The crankshaft includes a main shaft head and a secondary shaft portion. The main shaft head is fixedly mounted on the output shaft of the high-speed motor. The rotation axis of the main shaft head is consistent with the rotation axis of the output shaft of the high-speed motor. The axis of the secondary shaft portion is not colinear with the axis of the main shaft head. The movable plate is horizontally arranged on the lower side of the front part of the frame. The movable plate and the frame are connected by several elastic columns. The secondary shaft portion of the crankshaft cooperates with the movable plate. The secondary shaft portion of the crankshaft can drive the movable plate to swing horizontally back and forth relative to the frame. The shovel blade is fixedly connected to the front side of the movable plate. The blade extends out of the front side of the frame and contacts the floor.

[0015] As a preferred embodiment of the shovel lifter, the main shaft head of the crankshaft passes through the frame and extends downward, and the main shaft head of the crankshaft and the frame are matched through a bearing.

[0016] As a preferred embodiment of the shovel lifter, an assembly hole is provided on the upper end surface of the movable plate, the auxiliary shaft portion of the crankshaft extends into the assembly hole of the movable plate, and the auxiliary shaft portion and the wall of the assembly hole of the movable plate are fitted together by a bearing.

[0017] As a preferred embodiment of this shovel machine, the crankshaft also includes a main shaft neck, which is located between the main shaft head and the secondary shaft part. A balancing block is mounted on the side wall of the main shaft neck, and the center of gravity of the balancing block is located on the side away from the center line of the secondary shaft part relative to the center line of the main shaft head of the crankshaft.

[0018] As a preferred embodiment of the shovel lifter, a counterweight block is further included. The counterweight block is sleeved on the front part of the vehicle frame, and the counterweight block and the vehicle frame are fixedly connected.

[0023] 3. Beneficial effects

[0024] When this structure is adopted, the speed regulating motor of the walking mechanism can drive the driving wheel through the reducer to drive the lifting and shoveling machine to move as a whole, the high-speed motor of the rotating assembly drives the crankshaft of the shoveling assembly to rotate, and the auxiliary shaft of the crankshaft drives the moving plate to overcome the deformation of the elastic column itself and swing in a circular trajectory on the horizontal plane. The shovel blade follows the moving plate to shovel the floor on the ground, and the circular swing of the shovel blade can make the floor removal more thorough.

[0025] Installing a balancing block on the main shaft neck of the crankshaft can reduce the radial swing of the secondary shaft part of the crankshaft, which can not only stabilize the moving trajectory of the moving plate and reduce noise, but also increase the service life of the crankshaft.

[0026] The counterweight increases the overall weight of the shovel machine, moves the center of gravity of the shovel machine forward, and thus ensures that the shovel blade is in close contact with the working ground.

[0027] The articulation of the connecting frame of the hand-held assembly with the vehicle frame ensures that the driven wheel and the driving wheel are relatively independent. When encountering potholes and uneven ground, the driving wheel can be prevented from being suspended in the air to a certain extent, thereby affecting the balanced speed of travel and the smooth contact between the shovel and the ground.

[0028] This shovel machine can not only clear the floor, but also be used for: scraping and cleaning the floor; scraping and cleaning the floor glue; scraping and cleaning the floor tiles; scraping and cleaning the ceramic tiles; scraping and cleaning the plastic track; scraping and cleaning a variety of elastic floor materials, etc. BRIEF DESCRIPTION OF THE DRAWINGS
