[0002] Material transport vehicles are transport vehicles that are pushed and pulled by manpower. Although the material handling technology of hand-pushed material transport vehicles continues to develop, material transport vehicles are still used as an indispensable transport tool. Material transport vehicles are widely used in production and life because they are low-cost, simple to maintain, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use, and are very convenient for transporting lighter items over short distances.

[0003] After searching, the patent with application number 201921918677.8 discloses a material transport vehicle for construction projects, which belongs to the technical field of material transport vehicles for construction projects. A material transport vehicle for construction projects includes a material transport hopper, a threaded hole is opened in the middle of the front of the material transport hopper, a threaded rod is connected to the inner thread of the threaded hole, a clamp is arranged at one end of the threaded rod, a handle is fixedly connected to the end of the threaded rod away from the clamp, and a baffle is movably connected to the inner wall of the material transport hopper through a hinge, and a hook is fixedly connected to one side of the baffle; the utility model is provided by the coordination between the material transport hopper, the threaded hole, the threaded rod, the clamp and the handle. When the staff needs to transport the plate, they can first place the plate neatly in the material transport hopper, and then turn the handle to move the threaded rod, so that the clamp clamps and fixes the plate, ensuring that the plate is fixed more firmly and stably during transportation, and is not easy to tip over, thereby reducing the probability of damage to the plate during transportation.

The abutment block 124 abuts against the cylinder 125 at the bottom of the carriage 5 and pushes the cylinder 125 to move. The cylinder 125 drives the carriage 5 to rotate at a certain angle, and the carriage 5 is in an inclined state, so that more materials slide out faster.

[0028] A reversible material unloading base plate 8 is installed inside the carriage 5, and a lifting mechanism 9 for driving the material unloading base plate 8 to rotate is installed on the outer wall of the carriage 5. The lifting mechanism 9 includes a first motor 92, and a winding wheel 93 is sleeved on the output shaft of the first motor 92. A guide wheel 94 is installed on the top of the carriage 5, and a hanging seat 83 is installed on the material unloading base plate 8. A rope 95 is wound around the winding wheel 93, and one end of the rope 95 is passed around the guide wheel 94 and is fastened to the hanging seat 83.

[0029] The first motor 92 drives the winding wheel 93 to rotate, so as to realize the winding of the rope 95. The rope 95 pulls the hanging seat 83, thereby driving one end of the material discharge bottom plate 8 to rise, that is, the material discharge bottom plate 8 is in an inclined state, further accelerating the sliding out of the material, and overcoming the friction between the material and the material discharge bottom plate 8, so as to cause all the material to slide out;

[0030] The unloading bottom plate 8 includes a first plate 81, and the edge of the first plate 81 is connected to the second plate 82. The second plate 82 is set to be a plate with a triangular cross-section. When the unloading bottom plate 8 is in a horizontal state, one side of the second plate 82 is attached to the inner wall of the carriage 5 to prevent materials from entering between the unloading bottom plate 8 and the carriage 5. The first plate 81 is perpendicular to the second plate 82, and the bracket 83 is installed on the first plate 81.

[0034] Two sets of slide bars are connected between the fixed plate 121 and the inner wall of the bottom frame 1, and the two sets of slide bars are symmetrically arranged about the screw rod 123, and the abutment block 124 is slidably mounted on the slide bars to maintain the stability of the abutment block 124 during movement.

[0035] One end of the carriage 5 is provided with a baffle plate 6 which can be lifted and lowered, and a lifting mechanism 7 for driving the baffle plate 6 to be lifted and lowered is provided on the outer wall of the carriage 5. One end of the carriage 5 is an open design for discharging materials, that is, one end of the carriage 5 is a discharging port.

[0036] The lifting mechanism 7 comprises a cylinder 71 , one end of a piston rod of the cylinder 71 is connected to a Z-shaped connecting piece 72 , and a connecting block 73 connected to the connecting piece 72 is installed on the side wall of the baffle 6 .

[0037] The cylinder 71 drives the connecting member 72 to move upward, and the connecting member 72 drives the baffle 6 to move upward through the connecting block 73, so that the discharge port at one end of the carriage 5 is opened.

[0038] The inner wall of the carriage 5 is provided with a slide groove 51 , the baffle 6 is slidably installed inside the slide groove 51 , the side of the carriage 5 is provided with a through hole 52 connected with the slide groove 51 , and the connecting block 73 is movably installed inside the through hole 52 .

[0040] The surface of the second support block 4 is provided with a rubber pad to prevent the second support block 4 from rigidly contacting the carriage 5. Optionally, the second support block 4 and the carriage 5 can be locked by a buckle to prevent the carriage 5 of the material transport vehicle from bumping and shaking during transportation.

[0041] Two sets of handrails 10 are fixed to the upper part of the other end of the carriage 5, and a controller 11 is installed on one set of handrails 10, and the controller 11 is electrically connected to the first motor 92, the second motor 122 and the cylinder 71. Three control buttons are installed on the controller 11, which are used to control the first motor 92, the second motor 122 and the cylinder 71 respectively.

[0042] When in use, the material transport vehicle filled with materials is manually pushed to the designated position for unloading. First, the cylinder 71 is controlled to operate through the controller 11, and the cylinder 71 drives the connecting member 72 to move upward. The connecting member 72 drives the baffle 6 to move upward through the connecting block 73, so that the discharge port at one end of the carriage 5 is opened, and part of the material begins to slide out. Then the second motor 122 in the resistance mechanism 12 is controlled to operate, and the second motor 122 drives the screw rod 123 to rotate, and the screw rod 123 drives the resistance block 124 to move. The resistance block 124 resists the cylinder 125 at the bottom of the carriage 5 and pushes the cylinder 125 to move. The cylinder 125 drives the carriage 5 to rotate at a certain angle, and the carriage 5 is in an inclined state, so that more materials slide out faster.

[0043] When the height of the material in the carriage 5 is lower than the height of the second plate 82, the first motor 92 in the lifting mechanism 9 is controlled to operate, and the first motor 92 drives the winding wheel 93 to rotate, so as to realize the winding of the rope 95. The rope 95 pulls the hanging seat 83, thereby driving one end of the material discharge bottom plate 8 to be lifted, that is, the material discharge bottom plate 8 is in an inclined state, further accelerating the sliding out of the material, and overcoming the friction between the material and the material discharge bottom plate 8, so as to cause all the material to slide out;

[0044] After the material unloading is completed, the cylinder 71 drives the baffle 6 to reset, the first motor 92 drives the unloading bottom plate 8 to reset, and the second motor 122 drives the carriage 5 to reset.
