[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0026] like Figure 1-2 As shown, a gravel spreading loader for a dump truck includes a main body 4, a bolt 8 and a driving member. The main body 4 is connected to a car body 1 by welding or threaded fixing. The car body 1 includes at least two side walls. A dump door 2 is hinged at the rear of the car body 1. The upper edge of the dump door 2 is hinged at the rear of the car body 1 so that the dump door 2 can create a gap with the car body 1 by rotating, so that the gravel can be poured out through the gap between the dump door 2 and the car body 1 when the dump car body 1 is dumped.

[0027] In one embodiment, one main body 4 is provided, and the main body 4 is provided on one side of the carriage 1 and extends to the rear of the carriage. The main body 4 is provided on the lower edge of the side wall of the carriage 1, and a limiting hole extending along the front-rear direction of the dump truck is provided on the main body 4; the corresponding dump door 2 is provided with a bolt 8 corresponding to the main body 4, and the bolt 8 is respectively fixed to the side of the dump door 2 and extends into the corresponding limiting hole; the driving member extends into the limiting hole and is correspondingly connected to the bolt 8 to drive the bolt 8 to slide along the limiting hole to limit the opening and closing state of the dump door 2. Since the main body 4 of the carriage 1 is hard steel, one main body 4 installed on the side can meet the requirement of controlling the uniform opening and closing angle of the dump door 2.

[0028] Furthermore, in order to improve the accuracy of control, two main bodies 4 are provided, and the two main bodies 4 are respectively provided at the lower edges of the side walls of the two side compartments 1, for limiting the two sides of the dump door 2, and a limiting hole extending along the front and rear direction of the dump truck is provided on the main body 4. The two bolts 8 are respectively fixed on both sides of the dump door 2. The bolts 8 are metal columns, extending in the horizontal direction and extending into the corresponding limiting holes, so that the bolts 8 can be restricted by the limiting holes. A driving member for driving the bolts 8 is also provided on the main body 4. The driving member extends into the limiting hole and extends along the length direction of the limiting hole. The driving member is correspondingly connected to the bolts 8, so that the bolts 8 can be driven to slide along the limiting holes to limit the opening and closing state of the dump door 2, thereby controlling the amount of gravel spread according to the opening size of the dump door 2, providing an economical and efficient solution for the case where standard gravel spreader equipment is not available. Of course, the gravel spreading accuracy provided by the present application may not be as good as that of high-standard spreading equipment, but the requirements for the amount of gravel spread in actual construction are not strict. The present application can fully meet the needs of actual construction by adjusting the dump door 2.

[0029] In an optional embodiment, the driving member is a screw 5, and the threaded structure of the screw 5 has a high axial limiting ability when not rotating. While meeting the adjustment requirements, the bolt 8 can have a high stability in the limiting hole, thereby ensuring uniformity during the spreading process.

[0030] The screw 5 is threadedly assembled on the end of the main body 4 away from the carriage 1, and can be displaced along the length direction of the limiting hole by rotating. The end of the screw 5 extending into the limiting hole is rotatably connected with a hinge sleeve 6. Specifically, a rotating shaft extending along its axial direction is provided at the end of the screw 5, and a mounting hole corresponding to the rotating shaft is provided on the side of the hinge sleeve 6. A step with a reduced inner diameter is provided at the end of the mounting hole close to the rotating shaft, and a limiting flange corresponding to the step is provided at the end of the rotating shaft, thereby forming a rotating connection relationship. The door bolt 8 can be limited by the hinge sleeve 6 without affecting the rotation of the screw 5.

[0031] In an optional embodiment, one end of the screw rod 5 outside the limiting hole is connected to a corresponding rotating disk 3, and the rotating disk 3 is fixedly connected to the screw rod 5, thereby increasing the torque of the screw rod 5, making it easier to apply torque to rotate the screw rod 5 and drive the articulated sleeve 6.

[0032] The rotating disk 3 can be a circular disk or a rotating handle. Preferably, the rotating disk 3 is two rotating handles distributed in a cross shape, so that it is easy to turn the knob. Furthermore, the rotating handle can be a galvanized steel pipe, so that a force rod can be added to the rotating handle, so that the screw 5 can be adjusted when gravel squeezes the dump door 2.

[0033] In an optional embodiment, the shape of the articulated sleeve 6 is adapted to the width of the limiting hole, so that it can slide stably along the length direction of the limiting hole. The specific shape of the articulated sleeve 6 is a square block structure corresponding to the limiting hole. A articulated hole corresponding to the door bolt 8 is provided in the middle of the articulated sleeve 6. The screw 5 is connected to the side of the articulated sleeve 6 corresponding to the screw 5 by a rotational connection. A limiting groove corresponding to the side wall of the limiting hole is provided on the side wall of the articulated sleeve 6. At this time, the spacing between the bottom of the limiting grooves on both sides of the articulated sleeve 6 is adapted to the width of the limiting hole, thereby achieving a stable sliding connection relationship.

[0034] Of course, a limit groove can be opened, or the thickness of the hinge sleeve 6 can be greater than the thickness of the main body 4, and guide plates corresponding to the main body 4 can be welded on both sides to form a limit groove. Furthermore, welding two guide columns corresponding to the main body 4 twice on the hinge sleeve 6 can also achieve this purpose.

[0035] In the present application, during the rotation of the dump door 2, the bolt 8 and the hinge sleeve 6 will have a certain relative displacement. Since the opening of the dump door 2 is small, this displacement is very small. The gap formed by the transitional matching relationship between the bolt 8 and the hinge hole can meet the displacement requirement. However, in order to further strengthen the stability of the connection relationship, a waist-shaped hole 7 perpendicular to the extension direction of the limiting hole is provided in the hinge sleeve 6, and the bolt 8 extends into the waist-shaped hole 7. The waist-shaped hole 7 is used as a hinge hole to hinge the bolt 8. At this time, when the dump door 2 rotates, the bolt 8 can be displaced and adjusted along the waist-shaped hole 7, thereby meeting the displacement requirement of the bolt 8.

[0036] The width of the waist-shaped hole 7 is matched with the outer diameter of the bolt 8. After the bolt 8 extends out of the waist-shaped hole 7, a nut is threadedly connected, and the nut is close to the hinge sleeve 6, thereby further improving stability.

[0037] In an optional embodiment, the main body 4 is composed of two parallel steel bars, which are preferably fixed by welding. Nuts are welded on the side of the two steel bars away from the carriage 1 and threadedly assembled with the screw 5. This reduces the production difficulty and cost and meets the actual conditions of small construction sites.

[0038] In an optional embodiment, baffles 9 are detachably fixed on both sides of the dump door 2. The baffles 9 can be metal plates or rubber plates, preferably metal plates. The baffles 9 extend into the interior of the carriage 1 and are close to the inner wall of the carriage 1. Gravel is loaded when the dump door 2 is closed. After a gap is opened at the lower edge of the dump door 2, the gravel to be unloaded is blocked between the two sides of the dump door 2 and the side walls of the carriage 1, thereby ensuring that the gap at the lower edge of the dump door 2 is the only channel for the gravel, preventing the gravel from flowing out from both sides.

[0039] In this embodiment, the baffle 9 is a triangular or fan-shaped structure corresponding to the dump door 2. Taking the fan shape as an example, the fan-shaped radial direction corresponding to the baffle 9 is adapted to the distance between the hinge shaft of the dump door 2 and the inner cavity bottom plate of the carriage 1, so that the carriage 1 can be smoothly entered and exited during the rotation of the dump door 2. A flange is provided on the side of the baffle 9 close to the dump door 2, and the flange is fixed to the dump door 2 by bolts. In this way, the dump truck is improved according to actual needs and the construction cost is reduced. After the gravel spreading device is installed on the dump truck, the problems of slow speed, large spreading amount and difficult quality assurance of manual gravel spreading in small projects are solved, while the construction cost is also reduced and the work efficiency is greatly improved.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
