Description

Technical Field

[0001] The utility model relates to a ground cement pouring device, belonging to the technical field of cement pouring. Background Technique

[0002] A cement concrete road surface refers to a road surface with cement concrete as the main material for the surface layer, abbreviated as a concrete road surface. Cement concrete road surfaces include various road surfaces such as plain concrete, reinforced concrete, continuously reinforced concrete, and prestressed concrete; a cement concrete road surface consists of a cushion layer, a base layer, and a surface layer. Cement road surfaces are usually used to pave relatively narrow road surfaces. When paving, baffles are fixedly supported on both upper sides of the road surface, and then cement is poured between the baffles. Since the cement road surface is relatively narrow, large cement trucks cannot enter for pouring during cement pouring. Using a trolley to pull cement will increase the work intensity and reduce the work efficiency. For this reason, relevant equipment has been developed in the industry. For example, the Chinese utility model patent with the authorization announcement number CN213389627U discloses a cement concrete road surface pouring and leveling device, and specifically discloses a movable frame. One end of the frame is horizontally and rotatably provided with a compaction roller, and the other end is horizontally and rotatably provided with a turntable. The turntable can be horizontally slid to one side of the frame, and a slide rail cooperating with the turntable is horizontally and fixedly installed on the top of the other end of the frame; a plurality of corner compaction blocks with different shapes are circumferentially spaced and installed on the lower surface of the turntable, and the plurality of corner compaction blocks can all move up and down. When pouring the ground with this scheme, it is necessary to lay the cement on the ground first, and then manually push the frame to move back and forth until the road surface is leveled, which is relatively laborious; and when the cement on the ground is piled up relatively high, pushing the frame over will cause the frame to tilt, which is not convenient for leveling the road surface. Content of the Utility Model

[0003] The purpose of the utility model is to provide a ground cement pouring device. The utility model can simplify the construction steps and prevent the vehicle body from tilting due to relatively high cement accumulation, affecting the construction.

[0007] On the side of the rotating inner barrel of the aforementioned ground cement pouring equipment, a plurality of first connecting rods are fixedly connected, the end of the first connecting rod is connected with a second connecting rod, and the second connecting rod faces the inner bottom of the stirring barrel and is connected with a second scraping plate.

[0008] On the side of the rotating inner barrel of the aforementioned ground cement pouring equipment, a third connecting rod is fixedly connected, and the end of the third connecting rod faces the inner side wall of the stirring barrel and is connected with a third scraping plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, the raw materials are added into the cement stirring mechanism for stirring. After the stirring is completed, they are sent to the tipping hopper through the discharge port and then poured on the ground. The operator manually pushes the vehicle body forward for a certain distance, and the reciprocating movement mechanism makes the roller roll back and forth, spreading the cement poured on the ground. When the cement poured on the ground accumulates to a relatively high level, the roller will rise when passing through, thereby driving the I-shaped slider to move upward along the sliding frame. At this time, the spring at the lower end is in a stretched state, and the spring at the upper end is in a compressed state. With the elastic force of the spring and the gravity of the roller applied to the cement, and with the cooperation of the reciprocating movement mechanism, the cement pile can be spread quickly, and the vehicle body will not tilt. The first scraping plate can scrape off the cement attached to the roller, preventing a large amount of cement from adhering to the roller and affecting the construction.

[0013] 2. In the present utility model, the reciprocating movement mechanism rotates the first gear through the first motor. The first gear drives the second gear to rotate meshingly, causing the screw rod to rotate, so that the screw hole block on the screw rod moves along the screw rod. By controlling the forward and reverse rotation of the first motor, the forward and backward movement of the screw hole block is controlled, thereby controlling the forward and backward movement of the drum.

[0014] 3. In the present utility model, the cement mixing mechanism operates by driving the worm and worm gear reducer through the second motor. The worm and worm gear reducer causes the rotating inner cylinder to rotate, so that the first connecting rod, the third connecting rod, and the fifth connecting rod on the rotating inner cylinder rotate. The raw materials in the mixing barrel are stirred through the second connecting rod connected to the first connecting rod and the sixth connecting rod connected to the fifth connecting rod. The second scraper is used to prevent cement from adhering to the bottom of the mixing barrel, the third scraper is used to prevent cement from adhering to the side wall of the mixing barrel, and the fourth scraper is used to prevent cement from adhering to the side wall of the fixed inner cylinder.

[0015] 4. In the present utility model, by providing a baffle between the discharge port and the tipping hopper, it is possible to prevent the cement in the cement mixing mechanism from being poured onto the ground before being fully mixed. After mixing is completed, the baffle is rotated by the dial plate, so that the baffle no longer blocks between the discharge port and the tipping hopper, and the cement can normally fall from the discharge port to the tipping hopper.
