Description

Technical Field

[0001] This utility model relates to the field of road paving technology, and more specifically to an automatic plastering machine. Background Technology

[0002] To improve transportation, many remote areas are paving cement roads to harden the ground and facilitate vehicle passage.

[0003] According to the publication (announcement) number CN111677241B, published on December 18, 2020, an automatic plastering machine for construction is disclosed, including a rectangular support frame. A column is vertically arranged in the middle of the support frame, and a base is sleeved on the column. A plastering box is connected to the side wall of the base. Material conveying pipes are provided on the side walls at both ends of the base. One end of the material conveying pipe passes through the plastering box and communicates with its interior, and the other end of the material conveying pipe is connected to the discharge end of a pump. The upper end of the plastering box is open, and a material-pulling plate is hinged to two opposite inner side walls of the plastering box by a torsion spring. A bottom opening is provided on the lower section of the inner side wall of the plastering box, directly opposite the bottom of the material-pulling plate. The mortar outlet has a rotating shaft and a central shaft rotatably mounted inside the plastering box, with the rotating shaft positioned above the central shaft. Multiple first cams are spaced apart on the central shaft, and multiple second cams are spaced apart on the rotating shaft. A drive gear is fixed on the rotating shaft, and a driven gear meshing with the drive gear is fixed on the central shaft. The outlet and rotating shaft are located on opposite sides of a material feeding plate. An adjustment cavity is formed inside the base, and a through hole communicating with the adjustment cavity is formed on both the upper and lower surfaces of the base. A column moves through two through holes and the adjustment cavity. A toothed belt is provided on the side wall of the column, and a drive assembly meshing with the toothed belt is located inside the adjustment cavity. This device can control the flow rate of mortar flowing from the outlet per unit time, preventing excessive mortar overflow during the ascent or descent of the plastering machine, thus reducing mortar usage while ensuring the normal operation of the plastering process.

[0004] In the prior art, including the aforementioned patent, when paving roads, the roadbed is usually leveled first, then templates are set up on both sides of the road to prevent cement mortar from flowing out, and then mixed cement mortar is poured onto the roadbed. After that, workers will even out the cement mortar. However, the road paved in this way has poor flatness, which causes some bumps when vehicles pass through. Utility Model Content

[0005] The purpose of this invention is to provide an automatic plastering machine to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides an automatic plastering machine, including a track, a crossbar movably mounted on the track, an mounting block movably mounted on the crossbar, a pusher hopper mounted on the mounting block, and a handwheel symmetrically rotatably mounted on the crossbar. The handwheel is rotated to move the mounting block along the crossbar and change the orientation of the pusher hopper so that the orientation of the pusher hopper is the same as the direction of movement of the mounting block.

[0007] Preferably, the handwheel is equipped with a winch, and the pusher hopper extends into the mounting block and is equipped with a take-up reel.

[0008] Preferably, a first cable is provided between the take-up reel and the winch.

[0009] Preferably, a second cable is provided between the take-up reel and the mounting block.

[0010] Preferably, the mounting block is movably provided with a sleeve for limiting the rotation of the pusher hopper.

[0011] Preferably, each of the two handwheels is provided with a movable lever, and a spring is provided between the movable lever and the crossbar.

[0012] Preferably, a third cable passing through the sleeve is provided between the two movable rods, and a spring is provided between the sleeve and the crossbar.

[0013] Preferably, the crossbar is movably provided with a tenon block that matches the guide groove on the track.

[0014] Preferably, the tenon is provided with a knob for fixing it to the crossbar.

[0015] In the above technical solution, the automatic plastering machine provided by this utility model has the following beneficial effects: During operation, the track is moved to both sides of the road and leveled. Then, the crossbar is pushed to move along the track. The pusher bucket on the mounting block will push the excess cement mortar to move, so that the cement mortar is evenly distributed. When the crossbar moves to the end of the track, the handwheel is turned. The handwheel drives the mounting block to move along the crossbar, and the pusher bucket rotates relative to the mounting block. The cement mortar in the pusher bucket will be pushed to move until the mounting block moves to the next position (the position that the pusher bucket just pushed). The pusher bucket rotates 180° relative to the mounting block. At this time, the crossbar can be pushed to move in the opposite direction along the guide rail. The pusher bucket on the mounting block continues to perform the work of evenly distributing the material. The work is repeated, and the pusher bucket smooths the road surface. The pusher bucket is small, which can better move the cement mortar in it and fill the depressions in the area it passes through. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an automatic plastering machine includes a track 1, a crossbar 11 movably mounted on the track 1, a mounting block 12 movably mounted on the crossbar 11, a pusher hopper 13 mounted on the mounting block 12, and a handwheel 113 symmetrically rotatably mounted on the crossbar 11. Rotating the handwheel 113 causes the mounting block 12 to move along the crossbar 11 and changes the orientation of the pusher hopper 13 so that the orientation of the pusher hopper 13 is the same as the direction of movement of the mounting block 12.

[0025] In the above technical solution, during operation, the track 1 is moved to both sides of the road and leveled. Then, the crossbar 11 is pushed to move along the track 1. The pusher hopper 13 on the mounting block 12 pushes the excess cement mortar to move, so that the cement mortar is evenly distributed. When the crossbar 11 moves to the end of the track 1, the handwheel 113 is turned. The handwheel 113 drives the mounting block 12 to move along the crossbar 11, and the pusher hopper 13 rotates relative to the mounting block 12. The cement mortar in the pusher hopper 13 is pushed to move until the mounting block 12 moves to the next position (the position that the pusher hopper 13 just pushed). The pusher hopper 13 rotates 180° relative to the mounting block 12. At this time, the crossbar 11 can be pushed to move in the opposite direction along the guide rail. The pusher hopper 13 on the mounting block 12 continues to perform the material equalization work. The work is repeated. The pusher hopper 13 smooths the road surface. The pusher hopper 13 is small and can better move the cement mortar in it and fill the depressions in the area it passes through.

[0026] As a further embodiment of this utility model, a winch 114 is provided on the handwheel 113, the push hopper 13 extends into the mounting block 12 and is provided with a take-up reel 131, a first cable 133 is provided between the take-up reel 131 and the winch 114, and a second cable 121 is provided between the take-up reel 131 and the mounting block 12; during operation, the track 1 is moved to both sides of the road and leveled, then the tenon 111 on the crossbar 11 is moved so that the tenon 111 is aligned with the guide groove on the guide rail, and then the movable rod 115 is pushed to move the track 115. As the crossbar 11 moves along the track 1, the pusher hopper 13 on the mounting block 12 pushes away excess cement mortar, ensuring even distribution. When the crossbar 11 reaches the end of the track 1, both movable rods 115 are pressed simultaneously. The movable rods 115 tighten the third cable 134, pulling the sleeve 132 upwards. This causes the sleeve 132 to separate from the shaft of the pusher hopper 13, and the limiting block 116 on the movable rod 115 to separate from the handwheel 113. At this point, rotating the two handwheels 113 drives the winch 114. Rotation causes one of the two winches 114 to wind up the first cable 133 and the second cable 121, while the other winch 114 releases the first cable 133 and the second cable 121. This causes the mounting block 12 to move along the crossbar 11, and the pusher hopper 13 to rotate relative to the mounting block 12. The cement mortar in the pusher hopper 13 is pushed along by the pusher hopper 13 until the mounting block 12 moves to the next position (the position just pushed by the pusher hopper 13). The pusher hopper 13 then rotates 180° relative to the mounting block 12, releasing the movable rod 115. The moving rod 115 moves upward under the action of the spring, the limiting block 116 locks the handwheel 113 and the third cable 134 is released, the spring pushes the sleeve 132 downward and puts it on the shaft of the pusher hopper 13, locking the pusher hopper 13 on the mounting block 12. At this time, the crossbar 11 can be pushed to move in the opposite direction along the guide rail. The pusher hopper 13 on the mounting block 12 continues to perform the material leveling work. The pusher hopper 13 smooths the road surface. The pusher hopper 13 is smaller and can better move the cement mortar in it and fill the depressions in the area it passes through.

[0027] As a further embodiment of this utility model, a sleeve 132 for limiting the rotation of the pusher hopper 13 is movably disposed on the mounting block 12. Each of the two handwheels 113 is provided with a movable rod 115, and a limiting block 116 for limiting the rotation of the handwheel 113 is provided on the movable rod 115. A spring is provided between the movable rod 115 and the crossbar 11. A third cable 134 passing through the sleeve 132 is provided between the two movable rods 115. A spring is provided between the sleeve 132 and the crossbar 11. A tenon 111 adapted to the guide groove on the track 1 is movably disposed on the crossbar 11. A useful tenon 111 is provided on the tenon 11. The knob 112 is fixed to the crossbar 11. During operation, the track 1 is moved to both sides of the road and leveled. Then, the tenon 111 on the crossbar 11 is moved so that the tenon 111 is aligned with the guide groove on the guide rail. Then, the movable rod 115 is pushed to move the crossbar 11 along the track 1. The pusher hopper 13 on the mounting block 12 will push the excess cement mortar to move, so that the cement mortar is evenly distributed. When the crossbar 11 moves to the end of the track 1, the two movable rods 115 are pressed at the same time. The movable rods 115 drive the third cable 134 to tighten, pulling the sleeve 132 upward, so that the sleeve 132 and the pusher hopper 112 are aligned. When the shaft of rod 3 separates and the limiting block 116 on the movable rod 115 separates from the handwheel 113, the two handwheels 113 are rotated. The handwheels 113 drive the winches 114 to rotate. One of the two winches 114 winds up the first cable 133 and the second cable 121, while the other winch 114 releases the first cable 133 and the second cable 121, causing the mounting block 12 to move along the crossbar 11. The pusher hopper 13 rotates relative to the mounting block 12, and the cement mortar in the pusher hopper 13 is pushed and moved until the mounting block 12 moves to the next position (the position just pushed by the pusher hopper 13). The bucket 13 rotates 180° relative to the mounting block 12, releasing the movable rod 115. The movable rod 115 moves upward under the action of the spring, the limit block 116 locks the handwheel 113 and the third cable 134 is released. The spring pushes the sleeve 132 downward and onto the shaft of the push bucket 13, locking the push bucket 13 onto the mounting block 12. At this time, the crossbar 11 can be pushed to move in the opposite direction along the guide rail. The push bucket 13 on the mounting block 12 continues to perform the material leveling work. The push bucket 13 smooths the road surface, and the smaller size of the push bucket 13 allows it to move the cement mortar better and fill the depressions in the area it passes through.
