Therefore, traditional grinding machines are often not suitable for reasons such as equipment costs and convenience of use.

In the patent application publication number CN105133475B, a dust-proof road construction device is disclosed, which uses the threaded right pressure and simultaneous or synchronous rotation generated when the motor is driven to rotate, so that the grinding head can be driven to perform synchronous grinding rotation and left and right Translating, but only one motor is used, therefore, combined with the local protruding grinding amount, the equipment cost is reduced; and the dust suction device is used for dust suction in the grinding range to achieve a more efficient dust-proof effect; it is also set to be able to Using the motor to automatically adjust the height of the leg members, and using a spirit level, can quickly adjust the level of the entire equipment on site according to the actual contour of the road surface, making the adjustment more accurate and ensuring the processing flatness after grinding. However, it has the following disadvantages: once there is a large bump in the grinding range of the grinding head, it will block the forward movement of the grinding head, and may also cause the leg member at one end to be lifted away from the road surface, eventually resulting in the inability to complete the local grinding work on the road surface .

Contents of the invention

The purpose of the present invention is to provide a road smoothing construction device, which can smooth the bumps on the road layer by layer from top to bottom, can handle larger protruding objects on the road surface, and has a larger working range of the device.

In order to achieve the above object, the basic solution of the present invention is: a road smoothing construction device, comprising a shell with an open lower end, a support portion is provided at the lower end of the shell, a grinding mechanism is arranged inside the shell, and the grinding mechanism includes a sleeve that is rotatably connected to the shell. The sleeve and the driving part that drives the sleeve to rotate, the sleeve is provided with a rotating rod, the side wall of the rotating rod is provided with a bump, the side wall of the sleeve is provided with a strip hole for the bump to slide up and down, and the rotating rod is An elastic part is fixedly connected, the upper end of the elastic part is fixedly connected to the sleeve, and the rotating rod is fixedly connected with an annular ferrule on the side wall below the sleeve. There is a ring groove connected with the annular cavity, and several blocks are slidably connected in the ring cavity, and a horizontally arranged support rod is fixedly connected to the block. The support rod passes through the ring groove, and the end of the support rod away from the block is fixedly connected. There is a slider, the inner wall of the housing is provided with a chute for the slider to slide up and down, the lower end of the chute is provided with a first electromagnet, the slider is provided with a permanent magnet, and the magnetic pole of the permanent magnet is close to the first electromagnet. The magnetic poles of the first electromagnet are opposite, and the lower end of the rotating rod is fixedly connected with a grinding head for grinding.

The working principle of the basic solution is: when using the device, the device is first placed on the ground to be polished, and then the first electromagnet is energized to generate magnetism. Since the slider is provided with a permanent magnet opposite to the magnetic pole of the first electromagnet, after the first electromagnet generates magnetism, it will generate an adsorption force on the permanent magnet, and the slider is slidably connected in the chute, so the slider will slide along the The slot slides down. Since the slider is fixedly connected to the support rod, sliding down the slider will drive the support rod to move downward; while the support rod passes through the ring groove and is provided with a block at the end close to the rotating rod, and the block is slidably connected in the annular ferrule In the annular cavity, when the support rod moves downward, it will exert a downward force on the annular collar through the annular groove. At the same time, because the annular ferrule is fixedly connected to the rotating rod, and the rotating rod is slidably connected in the bar-shaped hole on the sleeve through the protrusion, so when the annular ferrule is subjected to a downward force, it will drive the rotating rod to move downward, thereby protruding The block slides down inside the bar hole. At the same time, since the elastic member is fixedly connected to the rotating rod, the elastic member will be elastically deformed when the rotating rod moves downward. When the lower surface of the grinding head at the lower end of the rotating rod touched the protrusion on the ground, the rotating rod would stop descending. Then start the driving part, and the driving part drives the sleeve to rotate. Because the projection on the rotating rod is slidably connected in the bar-shaped hole, when the sleeve rotates, the bar-shaped hole will exert force on the projection to drive the projection to move together, that is, to drive the rotating rod to rotate. The rotating rod rotates to drive the grinding head to rotate, so that the grinding head grinds the protrusions on the ground. Since an annular cavity is provided in the annular ferrule, an annular groove communicating with the annular cavity is provided on the side wall of the annular ferrule, and the block on the support rod is slidably connected in the annular cavity, so when the rotating rod rotates, The clamping block will slide in the annular cavity. That is, the clamping block is stable, and the relative motion between the clamping block and the rotating rod is generated under the action of the rotating rod, so the rotating rod has no influence on the support rod. When the grinding head grinds the protrusions, the first electromagnet will continue to exert a magnetic force on the permanent magnet, that is, the grinding head will be subjected to a downward force, so after the grinding head removes a layer of protrusions, the grinding head will continue to descend, so that the grinding head Continue sanding the next layer of protrusions. After the protrusions are polished, the driving part is stopped, and the first electromagnet is de-energized. Since the elastic member is in an elastic deformation state, the elastic member has an elastic restoring force on the rotating rod, so that the elastic member will drive the rotating rod to move upward until both the support rod and the projection are reset.

The beneficial effect of this basic solution is that: the present invention is provided with a bump on the side wall of the rotating rod, and the position of the sleeve corresponding to the bump is provided with a bar-shaped hole for the bump to move up and down, so that when the sleeve rotates, the length of the bar-shaped hole The side can push the block to move, thereby pushing the rotating rod and the grinding head to rotate. At the same time, by setting the annular ferrule, the support rod, the permanent magnet and the first electromagnet, when the first electromagnet drives the support rod to move, the support rod drives the annular ferrule to move, so that the annular ferrule drives the support rod and the grinding head downward When the rotating rod rotates, the annular ferrule rotates accordingly, the ring groove rotates, the support rod does not rotate, and the clamping block on the support rod is stably located in the annular cavity. The invention has simple structure, reasonable and ingenious design, high cost performance and high application value.
