[0001] The utility model relates to the technical field of mud and sand vehicles, in particular to an automatic dumping type convenient mud and sand vehicle. Background Art
[0002] Construction projects involve many operations, such as wall construction, wall painting, ground processing, etc., and when performing these operations, a lot of materials, such as mud and sand, are needed. After the mud and sand are transported from the material factory to the construction site, they are generally transported to the specific site where the mud and sand are needed by the workers on the construction site. The traditional simple mud and sand truck needs to be dumped manually after transportation, which has high labor intensity and slow construction progress. Although the existing automatic dumping mud and sand truck does not need manual dumping, it saves time and effort, but it needs to be driven and operated by specialized personnel and has high maintenance costs. At the same time, due to its large size, it cannot be used in occasions with limited space on construction sites. Therefore, there is an urgent need for a mud and sand truck that is widely applicable, has low maintenance costs, does not require specialized personnel to drive and operate, and can achieve automatic dumping. Summary of the invention
[0003] The utility model aims to provide a mud and sand vehicle which is widely applicable, has low repair and maintenance cost, does not require special personnel to drive and operate, and can realize automatic dumping, that is, an automatic dumping convenient mud and sand vehicle.
[0004] The utility model is realized by adopting the following technical solutions:
[0005] An automatic dumping convenient mud and sand truck comprises a truck bucket, a mounting plate, a push handle for operators to push the mounting plate to move, and four wheels located at the bottom of the mounting plate;
[0006] The truck bed is composed of a bottom plate, two side plates, a tail plate and a front plate. The two side plates are fixedly connected to the front plate and then fixed to the bottom plate. The tail plate is arranged between the rear ends of the two side plates. The top ends of the left and right ends of the tail plate are respectively hinged to the rear ends of the two side plates and the hinge axes are arranged in the left and right directions. The middle parts of the left and right ends of the tail plate are detachably fixedly connected to the two side plates.
[0007] The left side of the top surface of the mounting plate is provided with a mounting groove and a first strip-shaped placement groove whose length direction is arranged in the front-to-back direction in sequence from front to back, a motor is fixed in the mounting groove, a lead screw whose axial direction is arranged in the front-to-back direction is rotatably installed in the first strip-shaped placement groove, and the front end of the lead screw is rotated through the front side wall of the first strip-shaped placement groove and is fixedly connected to the output end of the motor, a sliding nut is provided on the lead screw, and the sliding nut is slidably connected to the first strip-shaped placement groove front and back, a first rotating rod is hinged on the top of the sliding nut, and the axial direction of the hinge shaft is arranged in the left-right direction, and the right side of the top surface of the mounting plate is provided with a lead screw whose length is arranged in the front-to-back direction. A second strip-shaped placement groove is arranged along the front-to-back direction, a sliding rod whose axial direction is arranged in the front-to-back direction and a slider slidably adapted to the sliding rod are fixed in the second strip-shaped placement groove, a second rotating rod is hinged on the top of the slider and the axial direction of its hinge axis is arranged along the left-right direction, one end of the first rotating rod that is not hinged to the sliding nut and one end of the second rotating rod that is not hinged to the slider are respectively hinged to the left and right end parts of the truck bed bottom plate symmetrically and the axial directions of their hinge axes are both arranged along the left-right direction, the two side plates of the truck bed are respectively rotatably connected to the left and right end parts of the rear part of the mounting plate and the rotating axes are both arranged along the left-right direction.
[0008] Working process: When the mud and sand truck needs to dump the mud and sand, start the motor, the lead screw rotates, and the sliding nut moves, thereby driving the first rotating rod to swing, the sliding block passively moves, and the second rotating rod swings, thereby causing the truck bed to tilt. Then, the fixed connection between the middle part of the left and right ends of the tail plate and the two side plates is removed, and the middle part of the tail plate is free. As the truck bed tilts, the tail plate rotates due to gravity, and the mud and sand automatically flows out due to gravity.
[0009] Furthermore, the specific implementation structure of the detachable and fixed connection between the middle parts of the left and right ends of the tail plate and the two side plates is as follows: a groove is provided in the middle parts of the left and right end surfaces of the tail plate, and through holes matching the grooves are provided on the two side plates. Fixed cylinders are fixed at positions corresponding to the through holes on the outer sides of the two side plates, and a limiting groove is provided on the inner wall of the fixed cylinder. A movable plate slides left and right in the limiting groove, a block matching the groove is fixed on the side of the movable plate close to the tail plate, and a pull rod whose outer end is exposed to the fixed cylinder is fixed on the side of the movable plate away from the tail plate, and a spring is sleeved on the pull rod, one end of the spring is fixed to a side surface of the movable plate away from the tail plate, and the other end of the spring is fixed to the inner wall of the limiting groove at one end away from the groove. When in use, pull the pull rod to make the movable plate slide along the inner wall of the limiting groove, thereby driving the block to slide, so that the block is out of the groove and the tail plate rotates. At this time, the spring is in an extruded state. Under the action of the gravity of the mud and sand, the mud and sand in the bucket are automatically dumped. When the dumping is completed, the left and right ends of the tail plate are placed close to the inner sides of the two side plates, and the pull rod is released. Under the action of the spring, the movable plate drives the block to be stuck in the groove, and the tail plate is limited and fixed to prevent leakage of mud and sand.
[0010] Furthermore, the left and right side portions of the top surface of the mounting plate, which are respectively located at the outer sides of the first strip placement groove and the second strip placement groove, are uniformly distributed along the front-to-back direction with a plurality of support piers for supporting the left and right sides of the bucket. When the bucket is in a horizontal state, the support piers provide support for the bucket, thereby sharing some gravity for the first rotating rod and the second rotating rod.
[0011] Furthermore, fixed plates are fixed to the left and right ends of the rear of the mounting plate, and the two side plates of the truck bed are rotatably connected to the two fixed plates respectively, so that the structure is concretized and standardized.
[0012] Furthermore, the push handle is fixed to the front end portion of the top surface of the mounting plate, thereby reducing the overall length of the mud and sand vehicle.
[0013] Furthermore, all four wheels are universal wheels, so that the mud truck can be used more flexibly.
[0014] The beneficial effects of the utility model are as follows: 1) The mud and sand truck described in the utility model conveniently realizes the tilting effect of the truck bucket through the ingenious cooperation of structures such as the lead screw, the sliding nut, the motor, and the rotating rod. When the mud and sand in the truck bucket needs to be unloaded, there is no need for manual unloading. Only the motor needs to be started to tilt the truck bucket, thereby facilitating the dumping of mud and sand, and no manual unloading is required, saving time and effort; 2) The mud and sand truck described in the utility model does not require special personnel to drive and operate, and general operators can operate it; 3) The mud and sand truck described in the utility model has no cab and is small in size.
