As shown in fig. 1-4, a counterweight return self-locking link mechanism for a weighing bin comprises a switch assembly for opening and closing the bottom of the weighing bin 1 and a link assembly for controlling the opening and closing of the switch assembly, wherein the switch assembly is fixed at the bottom of the weighing bin 1, and the link assembly is fixed on the side surface of the switch assembly. Set up switch module and link assembly in storehouse 1 bottom of weighing, through link assembly control switch module, conveniently control the accumulation and the release of storehouse 1 interior material of weighing to switch module can instantaneously accomplish the action of opening and shutting, and the overall process relies on the automatic realization of mechanics structure, and the complicated cooperation and the energy of multicomponent are extravagant when avoiding traditional motor control switch.

Further, the bottom of the weighing bin 1 is fixedly connected with a weighing bin flange 2 through a first fastener 7, and the switch assembly is hinged to the weighing bin flange 2. The storehouse flange 2 central authorities of weighing are equipped with hollow go-between, go-between size cooperation 1 bottom external diameter design in storehouse of weighing, and the circumference array has a plurality of mounting holes on the go-between, and bolt fastener passes the mounting hole with go-between and 1 section of thick bamboo wall fixed connection in storehouse of weighing, and go-between bottom fixed welding has the horizontally fixed plate, and both sides are provided with the protruding edge of buckling down the extension around the fixed plate for fixed connection switch subassembly and link assembly.

Further, the switch module bilateral symmetry sets up, including two switch boards 3 of controlling the concatenation formation, two 3 both ends of switch board are fixed connection respectively on two support risers 4, support riser 4 and articulate in the side of the storehouse flange 2 of weighing through first articulated elements 5. Two support risers 4 set up in fixed plate front and back both sides relatively to articulate on the protruding edge of fixed plate both sides through first articulated elements 5, support riser 4 sets up to the triangle-shaped structure, and two relative support risers 4 form the space of stepping down of triangle-shaped in the middle.

Furthermore, a counterweight rod 6 is arranged outside the switch board 3, and the counterweight rod 6 is fixed on the supporting vertical board 4 through a second fastener 15. The counterweight rod 6 is located the left and right sides of fixed plate, is fixed in both sides respectively through second fastener 15 and supports on the riser 4, and is preferred, and counterweight rod 6 fixed position is less than the vertical height of first articulated elements 5, and counterweight rod 6 is less than the distance of first articulated elements 5 to the 3 departments of opening and shutting of switch board to the distance of first articulated elements 5 to 5, thereby make under normal gravity, need not external force, only rely on the 6 effects of counterweight rod of both sides just can realize the 3 automatic closed states of switch board of both sides.

Further, the connecting rod assembly comprises a first connecting rod 8 and a second connecting rod 9, one ends of the first connecting rod 8 and the second connecting rod 9 are hinged to each other, the first connecting rod 8 and the second connecting rod 9 are hinged to each other through a second hinge 10, and the other ends of the first connecting rod 8 and the second connecting rod 9 are hinged to the supporting vertical plates 4 on the two sides through third hinges 14 respectively. Under the on-off state of switch board 3, first connecting rod 8 and second connecting rod 9 all are in horizontal position, just realize the articulated connection that the riser 4 was supported to the left and right sides, and first connecting rod 8 and second connecting rod 9 are provided with second articulated elements 10 in intermediate position, conveniently destroy the balance that the riser 4 was supported to both sides through external force to realize the open mode of switch board 3.

Further, an electromagnetic push rod 11 for pushing the second hinge part 10 to move upwards is arranged right below the second hinge part 10, and the electromagnetic push rod 11 is fixed on the side surface of the weighing bin flange 2. The electromagnetic push rod 11 is disposed directly under the first and

second links

8 and 9, preferably directly under the second hinge 10, so that only a small pushing force is required to break the balance between the first and

second links

8 and 9, so that the first and

second links

8 and 9 are relatively rotated, thereby achieving the open state of the switch panel 3. The electromagnetic push rod 11 is controlled by a signal, the push rod can break the balance between the first connecting rod 8 and the second connecting rod 9 only by applying a small force, the switch plate 3 is continuously opened under the action of gravity of the material at the moment, external force does not need to be additionally applied, and after the material is released, the switch plate 3 automatically returns to the original position under the action of gravity of the weight levers 6 on the two sides, so that the structure can realize the effects of automatic control and energy-saving loss of the switch plate 3.
