Abstract
Description
Technical Field
[0001] This utility model relates to the field of grader technology, and in particular to a grader screed device with adjustable ash and slag spreading thickness. Background Technology
[0002] The grader screed can evenly spread the ash (road base or subbase material) transported to the construction site and lay a smooth foundation for subsequent road surface pouring (such as asphalt or concrete) by initially leveling the ash.
[0003] In existing grader screed devices, the screeds mostly adopt an integral structure design. Since the screeds are in direct contact and friction with road construction materials such as ash and slag for a long time, and are subjected to vibration and impact during construction, local damage is unavoidable. However, due to the integral structure, even if only local damage occurs, the entire screed needs to be replaced, which not only wastes materials, but also increases maintenance costs and downtime. Summary of the Invention
[0004] This utility model relates to a grader screed device with adjustable ash and slag spreading thickness. The screed structure is designed to consist of multiple separate screed sections. By controlling the forward movement of the limiting base, the limiting base separates from the fixed base and no longer clamps or limits the separate screed sections. At this point, all the separate screed sections are in a state without mechanical locking, allowing workers to quickly disassemble and replace any damaged sections. This partial replacement method not only saves materials but also makes the screed section smaller and easier to replace. Furthermore, the device effectively controls the descent height of the separate screed sections by adjusting the motor and adjusting screw, allowing the descent height to be adjusted according to the required ash and slag spreading thickness, thus improving the adaptability of this screed device.
[0005] In a first aspect, this utility model provides a grader screed device with adjustable ash and slag spreading thickness, specifically comprising: an adjusting base; an adjusting motor fixedly installed at the top of the inner part of the adjusting base on the left side; an adjusting screw rotatably installed inside the adjusting base; the top of the adjusting screw on the left side being connected to the output shaft of the adjusting motor via a spline; a synchronous sprocket A fixedly installed on the outer circumference of each of the two adjusting screws; an installation assembly fixedly installed on the top of the adjusting base; and an adjusting slide block slidably installed inside the adjusting base; the adjusting... The sliding block is connected to the adjusting screw via threads; an opening and closing guide rail is fixedly installed on the inner side of the adjusting block; an opening and closing bolt is rotatably installed inside the opening and closing guide rail; a synchronous sprocket B is fixedly installed on the outer circumference of each of the two opening and closing bolts; a fixed base is fixedly installed between the two opening and closing guide rails; multiple sets of fixed plugs are fixedly installed on the front side of the fixed base; a limit base is slidably installed inside the opening and closing guide rail; multiple sets of auxiliary insertion holes are opened on the rear side of the limit base; a split ironing board body is inserted into each set of fixed plugs.
[0006] Preferably, the two synchronizing sprockets A are connected by a chain.
[0007] Preferably, the two synchronizing sprockets B are connected by a chain.
[0008] Preferably, the limiting base is also connected to the opening and closing bolt via threads.
[0009] Preferably, the limiting base is located in front of the fixed base.
[0010] Preferably, when the limiting base and the fixed base are connected, the auxiliary socket will be fitted onto the fixed plug.
[0011] Preferably, the limiting base clamps the split ironing plate body when it is connected to the fixed base.
[0012] This utility model provides a grader screed device with adjustable ash and slag spreading thickness, which has the following beneficial effects: (i) The ironing structure of this device is designed as a combination of multiple separate ironing plates. When it is necessary to replace a damaged part, simply rotate the opening and closing bolts to control the limiting base to move forward, thereby releasing the connection between it and the fixed base, and thus releasing the clamping limit on the separate ironing plate. At this time, each separate ironing plate is in the unlocked state, and the staff can quickly disassemble the damaged unit for replacement. This partial replacement mode not only greatly reduces material waste, but also the separate ironing plates are small in size, further reducing the difficulty and time consumption of the replacement operation.
[0013] (ii) By adjusting the coordination between the motor and the adjusting screw, this device can precisely control the descent height of the split screed body, so that it can be flexibly adjusted according to the thickness requirements of ash and slag paving, effectively improving the device's adaptability to different construction scenarios.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Please refer to Figures 1 to 5 Example 1: This utility model proposes a grader screed device with adjustable ash and slag spreading thickness, comprising: an adjusting base 1, an adjusting motor 101 (selected as a servo motor) fixedly installed at the top of the inner part of the left adjusting base 1; an adjusting screw 102 rotatably installed inside the adjusting base 1; the top of the left adjusting screw 102 is connected to the output shaft of the adjusting motor 101 via a spline; a synchronous sprocket A103 is fixedly installed on the outer circumference of each of the two adjusting screws 102; and an installation assembly 104 is fixedly installed on the top of the adjusting base 1, through which the screed is mounted. The device is installed at a suitable position on the grader. When the grader is running, the adjusting motor 101 rotates the adjusting screw 102, causing the adjusting screw 102 to lower the adjusting slide 2, fixed base 202, limiting base 207, and split-type screed body 206. This lowers the split-type screed body 206 to a suitable position for ash and slag spreading. The lowering height of the split-type screed body 206 can be adjusted by the adjusting motor 101, allowing the height of the screed device to adapt to changes in the required ash and slag spreading thickness. The adjusting base 1 has a slidingly mounted... Adjusting slide 2; adjusting slide 2 is connected to adjusting screw 102 via threads; an opening and closing guide rail 201 is fixedly installed on the inner side of adjusting slide 2; an opening and closing bolt 203 is rotatably installed inside the opening and closing guide rail 201; a synchronous sprocket B204 is fixedly installed on the outer circumference of each of the two opening and closing bolts 203; a fixed base 202 is fixedly installed between the two opening and closing guide rails 201; multiple sets of fixed plugs 205 are fixedly installed on the front side of the fixed base 202; a limiting base 207 is slidably installed inside the opening and closing guide rail 201; multiple sets of auxiliary insertion holes are opened on the rear side of the limiting base 207. 208; Each set of fixed plugs 205 is equipped with a split ironing plate body 206. If the split ironing plate body 206 is damaged, the opening and closing bolts 203 can be rotated to move the control limit base 207 forward, so that the limit base 207 is separated from the fixed base 202. Thus, the limit base 207 no longer cooperates with the fixed base 202 to clamp and limit the split ironing plate body 206. At this time, multiple split ironing plate bodies 206 are in a state of lack of mechanical locking, and the staff can quickly disassemble and replace the damaged split ironing plate body 206.
[0019] In Example 2, based on Example 1, the two synchronous sprockets A103 are connected by a chain; the two synchronous sprockets B204 are connected by a chain; the limiting base 207 is also connected to the opening and closing bolt 203 by threads; by designing the ironing structure in the device to consist of multiple split ironing plate bodies 206, and controlling the forward movement of the limiting base 207 by rotating the opening and closing bolt 203, the limiting base 207 can be separated from the fixed base 202 and no longer clamp and limit the split ironing plate bodies 206. At this time, the multiple split ironing plate bodies 206 are in a state of lack of mechanical locking, and the staff can quickly disassemble and replace the damaged split ironing plate bodies 206. This partial replacement method not only saves materials, but also makes the ironing plate smaller and easier to replace.
[0020] In Example 3, based on Example 2, the limiting base 207 is located in front of the fixed base 202; when the limiting base 207 and the fixed base 202 are connected, the auxiliary insertion hole 208 will be fitted onto the fixed plug 205; when the limiting base 207 and the fixed base 202 are connected, the split screed body 206 will be clamped. This device can effectively control the descent height of the split screed body 206 by adjusting the motor 101 and the adjusting screw 102, so that the descent height of the split screed body 206 can be adjusted according to the ash and slag spreading thickness requirements, thereby improving the adaptability of this screed device.
[0021] Working Principle: In use, the device is first securely mounted on the designated position of the grader using the mounting component 104. When the grader is operating, the adjusting motor 101 drives the adjusting screw 102 to rotate. Through the screw drive, the adjusting slide 2, the fixed base 202, the limiting base 207, and the split screed body 206 are lowered synchronously, allowing the split screed body 206 to descend to the appropriate height for ash and slag spreading. The descent height of the split screed body 206 can be precisely controlled by the adjusting motor 101, ensuring that the device can be flexibly adjusted according to the required spreading thickness of the ash and slag. When a split screed body 206 is damaged, the operator only needs to rotate the opening bolt 203, which controls the limiting base 207 to move forward, separating it from the fixed base 202 and releasing the clamping and limiting effect of both on the split screed body 206. At this time, all split screed bodies 206 are in the unlocked state, allowing for quick positioning and disassembly of the damaged unit for replacement. The operation is efficient and convenient.
