[0002] During the construction of bare concrete floors, the pouring and transportation of concrete is one of the key steps to ensure the quality of construction. At present, concrete pouring and transportation devices are mainly divided into three categories: conveyor belt systems, conveyor vehicles, and trolleys. Conveyor belt systems are suitable for large-scale construction sites and can continuously and stably transport concrete; conveyor vehicles are suitable for medium and long-distance concrete transportation; trolleys are suitable for short-distance transportation and are widely used in small or narrow construction sites.

[0003] The existing concrete pouring transport carts have some defects. Concrete is prone to sedimentation and stratification during transportation, which causes the raw materials to coagulate and directly affects the quality of concrete pouring. Traditional carts need to stop frequently for manual mixing, which not only increases the labor intensity of workers, but also reduces work efficiency and prolongs the construction period.

[0004] Therefore, a concrete pouring and transporting device for plain concrete floor construction is needed to solve the above-mentioned technical defects. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects: the concrete pouring and transporting device for the construction of the plain concrete floor not only realizes that the material can be automatically shaken by simply pushing the cart forward, thereby reducing the manpower consumption required for stopping for stirring, but also prevents the concrete hopper from being dislocated and shaken, thereby facilitating the on-site transportation of small amounts of concrete raw materials multiple times, and also realizes that it is convenient to transport concrete raw materials for different slope terrains;

[0015] (1) The device is provided with a bottom wheel, a driving sprocket, a transmission sprocket, a chain belt, a connecting rod, a turntable, and a concrete hopper.

When the concrete hopper swings, the connecting rod performs a swing arm movement as the turntable rotates, and the concrete hopper is pulled to swing by the lock of the hook and the movable block. When the cart stops, that is, the bottom wheel does not rotate, the cart is tilted backward and the concrete hopper is buckled with the limit hook to prevent the concrete hopper from being dislocated and shaking. The operation is simple and convenient, and it is convenient for on-site transportation of small amounts of concrete raw materials;

The extension length of the inner rod is adjusted, the locking bolts are loosened, and then the locking bolts are tightened after adjustment. When the center of gravity of the cart is slightly tilted backward, the foot supports the ground well. The adjustable support design facilitates transportation on different slopes and has better flexible transportation functions for various transportation sites. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the device adopts a human-powered propulsion method. When a person holds the handle 1 and pushes the device forward, due to the rotation of the bottom wheel 15, the torque is transmitted through the chain belt 13 between the active sprocket 14 and the transmission sprocket 12, driving the entire turntable 11 to rotate, thereby driving the two sets of connecting rods 9 to swing synchronously, constantly pulling the concrete hopper 4 to shake the material within a certain range, thereby preventing the concrete from solidifying and sinking to the bottom. The material can be automatically shaken by just pushing the cart forward.

[0026] Embodiment 2: The handle 1 is a rubber grip, and the handle 1 can be removed from the trolley frame 2. A set of limit hooks 3 are movably connected to the top of the trolley frame 2. The front end of the limit hook 3 is in a curved hook shape and can be buckled and fixed with the concrete hopper 4. The limit hook 3 can rotate within a range of 0-360°.

[0027] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, before the concrete hopper 4 swings, the limit hook 3 is lowered to release the limit between it and the concrete hopper 4. When the concrete hopper 4 swings, the connecting rod 9 performs a swing arm motion as the turntable 11 rotates, and the concrete hopper 4 is pulled to swing through the lock of the hook 7 and the movable block 8. When the cart stops, that is, the bottom wheel 15 does not rotate, the cart is tilted backward and the limit hook 3 is used to buckle the concrete hopper 4 to prevent the concrete hopper 4 from being dislocated and shaking.

[0030] Working principle: When the utility model is in use, the limit hook 3 is lowered to release the limit between it and the concrete hopper 4. After filling the concrete raw materials, the personnel hold the handle 1 and push the device forward. Due to the rotation of the bottom wheel 15, the torque is transmitted through the chain belt 13 between the active sprocket 14 and the transmission sprocket 12, driving the entire turntable 11 to rotate, thereby driving the two sets of connecting rods 9 to swing synchronously, and constantly pulling the concrete hopper 4 to shake the material within a certain range, thereby preventing the concrete from solidifying and sinking to the bottom. The material can be shaken automatically by simply pushing the cart forward. When the cart stops, that is, the bottom wheel 15 does not rotate, the cart is tilted backward and the limit hook 3 is used to buckle the concrete hopper 4 to prevent the concrete hopper 4 from being dislocated and shaking. The cart is supported on the ground by the support feet 19, the extended length of the inner rod 16 is adjusted, the locking bolts 17 are loosened and then tightened after adjustment, so that when the cart is slightly tilted backward to the center of gravity, the foot 20 can be well supported on the ground.
