[0026] As Figures 1 to 6As shown, the mortar small trailer includes a carriage 1, wheels 2 and a walking wheel assembly, the wheels 2 are arranged at the rear end of the bottom of the carriage 1, and the walking wheel assembly is arranged at the front end of the bottom of the carriage 1, the walking wheel assembly includes a support frame 3, walking wheels 4, a mounting bracket 5 and a brake unit, the support frame 3 is arranged on the bottom of the carriage 1 through a rotating connecting piece 6, the mounting bracket 5 is horizontally arranged on the bottom of the support frame 3 close to one side of the wheels 2, the walking wheels 4 are rotatably arranged at both ends of the mounting bracket 5, the brake unit includes a traction handle 7, a traction rod 9, a first hook claw 10, a brake baffle 11, a second hook claw 8 and a rotating shaft 12, the rotating shaft 12 is rotatably arranged at the end of the bottom of the support frame 3 away from the wheels 2, the traction handle 7 is arranged on the upper part of the rotating shaft 12, a clamping plate is rotatably arranged on the bottom of the traction handle 7 through a connecting shaft, the clamping plate is clamped on the rotating shaft 12, the end of the clamping plate away from the traction handle 7 is rotatably connected with the traction rod 9, the first hook claw 10 is rotatably arranged at the end of the traction rod 9 away from the rotating shaft 12, the second hook claw 8 is rotatably arranged at the end of the mounting bracket 5 away from the traction handle 7, the brake baffle 11 is arranged in the first hook claw 10 and the second hook claw 8, and the first hook claw 10 and the second hook claw 8 are located between the wheels 2 and the walking wheels 4. By arranging the brake unit, at the bumping position or the position needing to stop, only the traction handle 7 needs to be pushed towards the carriage 1 to make it rotate around the rotating shaft 12, at this time, the traction rod 9 drives the first hook claw 10 to move towards the side close to the walking wheels 4, because the second hook claw 8 is rotatably arranged on the mounting bracket 5, so the brake baffle 11 is driven to abut against the walking wheels 4 to limit the rotation of the walking wheels 4, thereby controlling the flexible stop and operation of the mortar small trailer, and the small trailer is more flexible and convenient for transporting concrete.

[0027] In the embodiment, the brake unit further includes a hanging plate 13 and a blocking column 14, the blocking column 14 is arranged on the support frame 3 along the width direction of the support frame 3, and the hanging plate 13 is rotatably arranged on the traction handle 7, the hanging plate 13 is clamped with the blocking column 14 when it rotates to the blocking column 14. When it is needed to stop, the hanging plate 13 on the traction handle 7 is rotated to the blocking column 14 to be clamped with the blocking column 14, at this time, the rotation of the traction handle 7 can be limited, so that the small trailer can be stably stopped.

[0028] In the embodiment, the first hook claw 10 and the second hook claw 8 are of the same specification, the first hook claw 10 and the second hook claw 8 are both provided with perforations 15 for the brake baffle 11 to pass through, and the length of the brake baffle 11 is greater than the distance between the two walking wheels 4. By arranging the first hook claw 10 and the second hook claw 8, the brake baffle 11 can be abutted on the walking wheels 4 to limit the rotation of the walking wheels 4, so as to achieve the purpose of stopping the small trailer.

[0029] The brake baffle 11 is an "L" shaped steel plate, and the inner corner of the brake baffle 11 is arranged towards the walking wheels 4. The "L" shaped steel plate has low cost, is simple, convenient and practical, and the inner corner of the brake baffle 11 is arranged towards the walking wheels 4, so that the rotation of the walking wheels 4 is more stably limited.

[0030] In the embodiment, the cleaning assembly includes a water tank 16, a water pump 17 and a fixing frame 18. The water tank 16 is arranged at the front end of the carriage 1, the output end of the water tank 16 is connected to the input end of the water pump 17, the water pump 17 is arranged on the carriage 1 through the fixing frame 18, and the output end of the water pump 17 is connected to a water pipe to clean the concrete on the inner wall of the carriage 1. The cleaning assembly includes the water tank 16, the water pump 17 and the fixing frame 18, the connection between the water tank 16 and the water pump 17 and the connection between the water pump 17 and the water pipe are prior arts, and thus will not be described in detail. The cleaning assembly can clean the residual concrete on the inner wall of the carriage 1 at any time, thereby ensuring that the volume of the carriage 1 is not excessively affected. In addition, water can be added to the concrete according to requirements.

[0031] In the embodiment, the bottom wall of the carriage 1 is concave, a discharge port 19 is arranged at the concave portion of the end of the carriage 1 close to the wheel 2, and a rotary discharge door assembly is arranged at the discharge port 19.

[0032] The rotary discharge door assembly includes a discharge chute 21, a connecting frame 22, a rotating handle 23 and a door 20. The discharge port 19 is connected to the discharge chute 21 away from the carriage 1, the connecting frame 22 is arranged at both sides of the discharge port 19, the rotating handle 23 is arranged on the connecting frame 22, the rotating handle 23 is located above the discharge chute 21, and the door 20 is arranged on the shaft diameter of the rotating handle 23 in the discharge chute 21. The rotating handle 23 is threadedly connected to the connecting frame 22. The rotating handle 23 is rotated to drive the door 20 to rotate, so that the discharge port 19 is opened or closed.

[0033] In the embodiment, the rotating connecting piece 6 includes a rotating disc 24, a rotating rod 25 and a base 26. The rotating disc 24 is connected to the bottom of the carriage 1, the rotating rod 25 is arranged at the bottom of the rotating disc 24, the rotating rod 25 is rotatably arranged in the base 26, and the base 26 is arranged on the supporting frame 3.

[0034] The use method is as follows: the concrete is unloaded from the concrete tank truck into the carriage 1 of the small trailer, then the traction handle 7 is pulled, so that the device can be moved. Since the rotating connecting piece 6 is arranged, the traction handle 7 can be pulled to the direction in which the small trailer needs to be moved, so that the whole small trailer is moved. When the brake is needed, the traction handle 7 is pushed to the direction close to the carriage 1, so that the traction handle 7 is rotated around the rotating shaft 12. At this time, the traction rod 9 drives the first hook claw 10 to move to the side close to the walking wheel 4. Since the second hook claw 8 is rotatably arranged on the mounting frame 5, the brake baffle 11 is abutted with the walking wheel 4, and the hanging plate 13 on the traction handle 7 is rotated to the blocking column 14 and is clamped with the blocking column 14, so that the rotation of the walking wheel 4 is limited. When the small trailer continues to move, the hanging plate 13 is separated from the blocking column 14, the traction handle 7 is pulled to the direction away from the carriage 1, and the small trailer can be moved.

[0035] The utility model has been described in combination with the drawings above, but is not limited to the protection scope of the utility model, and various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
