Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a roadbed gridding device. Background Art

[0002] Before backfilling the roadbed, it is usually necessary to draw grids on the roadbed in order to control the amount of backfill soil. The current practice is to first draw lines on the roadbed in the length direction of the roadbed, and then draw lines in the width direction of the roadbed, so that the criss-crossing lines form a grid on the road surface; finally, a hand-held shovel is used to shake the white lime onto the surface of the roadbed along the straightened lines.

[0003] Since the ash is spread manually along the line, the amount of ash that the shovel can hold each time is limited, which easily leads to a short length of the line each time; at the same time, due to the large distance between the shovel and the roadbed, a large amount of dust is easily generated during the falling process of the ash; in particular, the above method is not only inefficient, but also time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to provide a roadbed gridding device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roadbed gridding equipment, comprising a mobile trolley, a hopper installed on the mobile trolley, and a discharge piece is provided at the bottom of the mobile trolley; the mobile trolley is moved along the road surface to spread the lime in the hopper on the road surface through the discharge port on the discharge piece; a telescopic mechanism is also provided at the upper end of the hopper, and the telescopic mechanism comprises an end cover, and a telescopic rod is slidably installed on the end cover; one end of the telescopic rod completely penetrates the hopper and is flush with the outer surface of the discharge port; the telescopic rod slides in the end cover to promote the lime to flow smoothly and continuously through the discharge port to the ground.

[0006] As a preferred technical solution of the utility model: the end cover is also provided with a guide hole for guiding the telescopic rod to slide, and the telescopic rod is driven to slide upward or downward on the end cover by a motor.

[0007] As a preferred technical solution of the utility model: a rotating wheel is provided on the output shaft of the motor, the rotating wheel is eccentrically arranged with a linkage rod, and the telescopic rod is driven to slide upward or downward on the end cover through the linkage rod.

[0008] As a preferred technical solution of the utility model: the linkage rod is also provided with a latch pin, and is separated from the linkage rod by the latch pin, so as to facilitate the separation of the telescopic rod from the linkage rod.

[0009] As a preferred technical solution of the utility model: the hopper is movably connected to the moving trolley, and the end cover is movably connected to the upper end of the hopper.

[0010] As a preferred technical solution of the utility model: the material discharging piece is threadedly matched with the internal threaded hole provided on the moving trolley through the external threaded portion provided.

[0011] As a preferred technical solution of the utility model: a push rod is further provided on one side of the moving trolley, and the moving trolley is urged to move by the push rod.

[0012] By adopting the above technical scheme, the beneficial effects of the utility model are: 1. The mobile cart is used to move on the road surface, and the lime flows to the road surface through the discharge port to form a lime line on the road surface. At the same time, the mobile cart is used to carry the hopper, so that the equipment can carry a large amount of lime at the same time, and the discharge part is located under the mobile cart, so the gap between the discharge port and the road surface can be narrowed, so that the mobile cart will not generate a lot of dust when moving, thereby effectively solving the problem of low efficiency, time and effort in manual line drawing.

[0013] 2. As the telescopic rod slides up and down inside the end cover, it can avoid the phenomenon of "bridging" at the discharge port, which makes it difficult for the ash to flow smoothly and continuously to the road surface. As a result, the equipment can discharge smoothly and the gray-white line drawn has a continuous and uninterrupted effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: a roadbed gridding device, comprising a mobile trolley 1, a hopper 2 mounted on the mobile trolley 1, and a discharge piece 5 is provided at the bottom of the mobile trolley 1; the mobile trolley 1 moves along the road surface to lay the lime in the hopper 2 on the road surface through a discharge port 6 on the discharge piece 5;

[0021] To summarize, the mobile cart 1 is used to move on the road surface, and the lime flows to the road surface through the discharge port 6 to form a lime line on the road surface. The mobile cart 1 is used to carry the hopper 2, so that the device can carry a large amount of lime at the same time to extend the length of the single line drawn by the device. At the same time, the discharge member 5 is located below the mobile cart 1, so the gap between the discharge port 6 and the road surface can be narrowed, so that the mobile cart 1 does not generate a large amount of dust when moving. The mobile cart 1 is used to move along the length direction of the road surface to draw the gray-white line in the length direction, and then move along the width direction of the road surface to draw the gray-white line in the horizontal direction to complete the drawing of the roadbed grid, thereby effectively solving the problems of low efficiency, time and effort in manual line drawing.

[0022] Furthermore, since a telescopic mechanism 3 is also provided at the upper end of the hopper 2, the telescopic mechanism 3 includes an end cover 33, and a telescopic rod 35 is slidably installed on the end cover 33; one end of the telescopic rod 35 completely penetrates the hopper 2 and is flush with the outer surface of the discharge port 6; the telescopic rod 35 slides in the end cover 33 to promote the lime to flow smoothly and continuously through the discharge port 6 to the ground.

[0023] Therefore, the telescopic rod 35 can be used to slide upward or downward on the end cover 33. In particular, the bottom end of the telescopic rod 35 passes through the discharge port 6. Therefore, when the telescopic rod 35 slides up and down, it can pierce the "bridge" phenomenon formed at the discharge port 6, thereby ensuring that the white ash can flow continuously and uninterruptedly to the road surface. This can further improve the line drawing quality of the device.

[0024] On the basis of the above scheme, since the end cover 33 is also provided with a guide hole 34 for guiding the sliding of the telescopic rod 35, and the telescopic rod 35 is driven by the motor 30 to slide upward or downward on the end cover 33, the telescopic rod 35 can be automatically extended and retracted, thereby enabling the device to further improve the line drawing quality and reduce manpower expenditure.

[0025] Furthermore, since the output shaft of the motor 30 is provided with a rotating wheel 32, the rotating wheel 32 is eccentrically arranged with the provided linkage rod 36, and the linkage rod 36 drives the telescopic rod 35 to slide upward or downward on the end cover 33. Therefore, through the above-mentioned method, when the rotating wheel 32 rotates, the linkage rod 36 can be linked with the rotating wheel 32, thereby driving the telescopic rod 35 to reciprocate upward or downward to ensure the smooth outflow of the white ash. In addition, the end cover 33 is also provided with an electric control box 31, and the motor 30 is fixed on the electric control box 31. Therefore, devices such as batteries can be installed in the electric control box 31 to provide power to the motor 30 and ensure the normal operation of the motor 30.

[0026] In order to facilitate the disassembly and assembly of the linkage rod 36 and the telescopic rod 35, a latch 37 is further provided on the linkage rod 36, and the latch 37 is used to separate the linkage rod 36, so that the telescopic rod 35 and the linkage rod 36 can be separated. Therefore, the connection between the telescopic rod 35 and the linkage rod 36 is achieved by inserting the latch 37 into the linkage rod 36, and vice versa, the telescopic rod 35 and the linkage rod 36 can be separated by pulling out the latch 37, so that the user can open the end cover 33 and then add lime to the hopper 2 again, and it is also convenient to disassemble the above parts for maintenance and care.

[0027] In addition, since the hopper 2 is movably connected to the mobile cart 1, it is convenient to disassemble the hopper 2 for replacement and maintenance of the hopper 2; at the same time, the end cover 33 is movably connected to the upper end of the hopper 2, which makes it convenient to disassemble the end cover 33 and the hopper 2; therefore, the cover plate 33 can not only seal the upper end of the hopper 2 to reduce dust generation while affecting the lime filling, but also guide the telescopic rod 35 to slide.

[0028] Specifically, a screw is provided on the mobile trolley 1, and the screw passes through the bottom of the hopper 2 and is connected to a nut, so that the hopper 2 and the mobile trolley can be movably connected; the end cover 33 and the upper end of the hopper 2 are preferably fixed in a threaded manner.

[0029] Furthermore, since the discharge piece 5 is threadedly matched with the internal threaded hole 8 provided on the moving trolley 1 through the external threaded portion 7, the disassembly of the discharge piece 5 is simple and convenient, so as to facilitate the replacement of different discharge pieces 5, that is, it is convenient to replace the discharge piece 5 with discharge ports 6 of different sizes.

[0030] Furthermore, a push rod 4 is provided on one side of the mobile cart 1 , and the mobile cart 1 is moved by the push rod 4 , so that the user does not need to bend down when the mobile cart 1 moves, so that the user can control the movement of the mobile cart 1 .

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
