Description

Technical Field

[0001] The utility model relates to the technical field of road material testing instruments, in particular to a cement mortar wear-resistant testing machine capable of automatically cleaning powder. Background Art

[0002] When a vehicle is driving on the road, the repeated action of the wheel load will reduce the wear resistance of the road surface. Abrasion resistance is closely related to the road's anti-rutting ability and durability, and is one of the important indicators for evaluating the performance of materials. Weak abrasion resistance will affect its road use effect. Therefore, effective testing of cement mortar wear resistance is of great significance.

[0003] In the prior art, a large amount of cement dust and stone slag will be generated during the use of the wear-resistant testing machine. The cement dust will diffuse in the air and will be inhaled by people around, causing harm to the human body. The stone slag will be blown away by the wear-resistant testing machine running at high speed and may injure people around. Therefore, a cement mortar wear-resistant testing machine with automatic powder cleaning is proposed to solve the above problems. Utility Model Content

[0007] The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a cement mortar wear resistance testing machine for automatically cleaning powder comprises a cabinet body, the front side of the cabinet body is slidably connected with a return frame extending into the interior thereof, the opposite side of the return frame is fixedly connected with a sliding rod symmetrically distributed front and back, the outer side of the sliding rod is slidably connected with a clamping block symmetrically distributed left and right, the outer side of the sliding rod is fixedly connected with the same placement plate that is adapted to the clamping block, the bottom of the placement plate is provided with a fixing component that is hinged with the clamping block and extends to the front side of the return frame, the right side of the cabinet body is provided with a drain valve connected thereto, the top of the cabinet body is provided with a grinding component that extends into the interior thereof and is movably connected thereto and is adapted to the placement plate, the rear side of the cabinet body is fixedly connected with a dust removal chamber, the rear wall of the inner cavity of the cabinet body is provided with an oblique downward through hole connected to the dust removal chamber, the bottom of the dust removal chamber is fixedly connected with a sewage pipe connected thereto, and the interior of the dust removal chamber is provided with a dust removal component that is connected to the outside and adapted to the oblique downward through hole.

[0008] The beneficial effects of the utility model are as follows: first, the return frame is pulled out of the cabinet, a proper amount of water is added into the cabinet, a cement mortar block is placed above the placement plate, and the clamping block is driven to move to the opposite side by rotating the fixing assembly, thereby clamping the cement mortar block above the placement plate, and the return frame is pushed into the cabinet, and the grinding assembly and the dust removal assembly are started. The grinding assembly grinds the cement mortar block, and the cabinet prevents stone slag from randomly splashing. The stone slag falls into the water at the bottom of the cabinet, and part of the dust is absorbed by the water at the bottom of the cabinet. The dust generated by the grinding enters the dust removal chamber through the oblique downward through hole under the suction force of the dust removal assembly, and the dust removal assembly makes the dust contact with the water mist to become sewage and is discharged through the sewage pipe.

[0009] The cement mortar wear tester with automatic powder cleaning function has the advantages of collecting the generated dust to prevent it from spreading in the air and grinding in a closed space to prevent stone slag from splashing.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the fixing assembly includes a threaded rod, an articulated seat and a connecting rod. The bottom of the placement plate is rotatably connected to a threaded rod extending to the front side of the return frame. The outer side of the threaded rod is threadedly connected to articulated seats that are symmetrically distributed front to back and are slidingly connected to the bottom of the placement plate. Connecting rods are hinged on both sides of the articulated seat. The ends of the connecting rods away from the articulated seat are hinged to adjacent clamping blocks. The thread directions of the front articulated seat and the rear articulated seat are opposite.

[0012] The beneficial effect of adopting the above further scheme is that when the threaded rod is rotated, the force generated by the rotation of the thread causes the hinge seat to move to the opposite side, and then drives the clamping block to move to the opposite side through the connecting rod, thereby clamping the cement mortar block above the placement plate.

[0013] Furthermore, the grinding assembly includes a fixed frame, an electric push rod, a motor and a grinding disc. The top of the cabinet is fixedly connected to the fixed frame, and an electric push rod is provided inside the fixed frame. The output end of the electric push rod is fixedly connected to a motor that is slidably connected to the fixed frame and the output end extends to the inside of the cabinet and is movably connected to the cabinet. The output end of the motor is fixedly connected to a grinding disc that is adapted to the placement plate.

[0014] The beneficial effect of adopting the above further scheme is that when the electric push rod and the motor are started, the output end of the motor drives the grinding disc to rotate, and the output end of the electric push rod drives the motor and the grinding disc to contact the top of the cement mortar block, so that the cement mortar block can be ground.

[0015] Furthermore, the dust removal assembly includes an atomizing nozzle, a high-pressure water pipe, an exhaust fan and a filter. The top wall of the inner cavity of the dust removal chamber is provided with atomizing nozzles that are distributed at equal distances laterally and are all adapted to the downward oblique through holes. The top of the dust removal chamber is provided with a high-pressure water pipe that is connected to the atomizing nozzles. The rear wall of the inner cavity of the dust removal chamber is provided with an exhaust fan that is connected to the outside and is adapted to the downward oblique through holes. The front side of the exhaust fan is fixedly connected to a filter that is adapted to it.

[0016] The beneficial effect of adopting the above further scheme is that the exhaust fan is started, and then the dust generated by grinding the cement mortar blocks of the cabinet is sucked into the dust removal chamber through the downward inclined through hole, and the high-pressure water pipe transports water to the atomizing nozzle at high pressure. The water mist sprayed by the atomizing nozzle contacts with the dust and then forms sewage, which is discharged through the sewage pipe. The filter can further filter the discharged gas.

[0017] Furthermore, the roll frame and the cabinet are sealed.

[0018] The beneficial effect of adopting the above further solution is that the return frame and the cabinet body are sealed to prevent dust from escaping when the device is running. BRIEF DESCRIPTION OF THE DRAWINGS
