The name of the invention is an electric energy meter destruction device, which arranges an electric drill that can be driven by a driving device to move vertically above the equipment destruction station. The electric drill can be driven by the driving device to move toward the electric energy meter entering the equipment destruction station on the conveyor belt to achieve destruction of the electric energy meter. However, it can only destroy one electric energy meter at a time, and the efficiency of destroying the electric energy meter is very low. Summary of the invention

[0004] The present invention overcomes the disadvantage of low meter destruction efficiency in the prior art and provides a meter destruction cutter device which can destroy meters in batches, thereby effectively improving the meter destruction efficiency and achieving good meter destruction effect, thereby preventing meters from returning to the market.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a meter destroying cutter device, characterized in that it includes a driving device and a mounting plate, the driving device drives the mounting plate to move, and a plurality of rows of parallelly arranged cutters are arranged on the mounting plate.

[0006] In the present invention, by arranging a plurality of rows of cutters on the mounting plate, a plurality of meters can be destroyed at one time, which can effectively improve the efficiency of meter destruction. When the cutters are destroying the meters, the positions of the meters can be prevented from being shifted, so that the effect of meter destruction is better. In addition, since the meters are placed in a box when they are destroyed, the box can prevent the parts of the destroyed meters from splashing, so that it is very convenient to collect the destroyed parts of the meters.

[0007] Preferably, a plurality of parallel T-shaped slots are arranged in the length direction of the mounting plate, one end of the T-shaped slot is opened, and a T-shaped strip matching with the T-shaped slot is arranged on the cutting knife.

[0008] The T-shaped bar can be inserted into the T-shaped slot from an opening at one end of the T-shaped slot, making it more convenient to install the cutter.

[0009] Preferably, it also includes an isolation cover arranged at the bottom of the mounting plate, with both ends of the isolation cover in the length direction penetrating, and both sides of the isolation cover in the width direction being mounted on both sides of the sliding track; a through groove cooperating with the cutter is penetrated on the upper end surface of the isolation cover.

[0010] The through groove is arranged to prevent the cutter from bringing out parts of the meter from the isolation cover during the upward movement of the cutter after the cutter destroys the meter.

[0011] Preferably, transparent observation windows are provided on both sides of the isolation cover in the width direction.

[0012] The transparent observation window allows easy observation of the interior of the isolation cover.

[0013] Preferably, auxiliary abutment components are provided on both sides of the mounting plate in the length direction, and the auxiliary abutment components include a fixed plate and an abutment plate, the fixed plate is fixedly connected to the mounting plate, and the abutment plate is movably connected to the fixed plate.

[0014] The abutment piece is movably arranged on the fixed plate, so that the abutment piece can assist in clamping the box and play an auxiliary supporting role.

[0015] Preferably, a fixing hole is penetrated through the fixing plate, a guide column cooperating with the fixing hole is provided on the abutment plate, an abutment spring is sleeved on the guide column, the abutment spring abuts between the fixing plate and the abutment plate, and an inclined surface and an abutment surface are provided from bottom to top on the side of the abutment plate close to the cutter.

[0016] When the cutter acts on the meter, the edge of the box contacts the inclined surface and the abutment surface in turn. When the cutter damages the meter, the abutment surface abuts against the side surfaces at both ends of the length direction of the box. The side surfaces at both ends of the length direction of the box are abutted by the abutment plate, which can effectively prevent the box from deformation.

[0017] Preferably, a plurality of piston cavities are provided at the bottom of the fixed plate, a guide column is provided on the abutment plate, a piston head cooperating with the piston cavity is provided at the end of the guide column, and an abutment spring is sleeved on the guide column; an oil chamber is provided at the upper part of the fixed plate, and the oil chamber and the piston are connected through an oil channel; a switch structure for controlling the oil channel switch is provided on the side wall of the oil channel.

[0018] The abutment plate and the fixed plate are provided to assist in clamping the box. Although the abutment plate can clamp the sides of the box to a certain extent, the clamping force of the abutment plate is provided by the abutment spring. Therefore, in the process of destroying the meter, the abutment force of the abutment spring is limited and in a "soft abutment" state, the meter will still be displaced in the box, causing the surface of the box to deform. Therefore, the switch of the oil channel is controlled by the switch structure so that the abutment plate can form a hard connection.

[0019] Preferably, the oil channel is vertically arranged in the fixed plate, and the switch structure includes an abutment button, on which a locking column is arranged; a locking hole is horizontally arranged in the fixed hole, the locking hole is connected to the oil channel, and the locking column is slidably arranged in the locking hole, and a locking spring is sleeved on the locking column, and the locking spring abuts between the fixed plate and the abutment button; the abutment button is sequentially provided with a guide surface and a locking surface from bottom to top; an isolation cover is provided at the bottom of the mounting plate, and both ends of the isolation cover in the length direction are penetrated, and both sides of the isolation cover in the width direction are mounted on both sides of the sliding track; both ends of the isolation cover are provided with locking grooves that cooperate with the fixed plate, and the driving device drives the mounting plate to move downward, and when the cutter destroys the timing meter, the locking surface abuts against the side wall of the locking groove, and the locking groove pushes the locking column to penetrate into the oil channel to block the oil channel.

[0020] As the hydraulic cylinder drives the mounting plate to move downward, the abutment plate gradually abuts against the side wall of the box. During the abutment process, the piston head on the guide column slides in the piston cavity, so that the hydraulic oil in the piston cavity is pressed back into the oil cavity through the oil channel; when the abutment panel is clamped at both ends of the box, as the cutter continues to descend, the guide surface and locking surface on the abutment button abut against the side wall of the locking groove in turn. During the action process, the locking groove pushes the abutment button to move in the direction of the fixed plate, so that the locking column crosses the oil channel to block the oil channel; so that the hydraulic oil in the sealing cavity cannot pass through the oil channel The oil returns to the oil chamber through the oil channel; at this time, the piston head cannot move in the piston chamber, so that the abutment plate is in a "hard abutment" state, and due to the initial force of the abutment spring, the abutment plate is tightly fitted with the side wall of the box, so that even if the force applied by the cutter on the meter is greater, the surface of the box will not be deformed due to the effect of the "hard abutment"; when the meter is cut, the abutment button is disengaged from the abutment groove, and the locking column is pushed away from the oil channel by the force of the locking spring, so that the oil channel is reopened, and then the abutment plate is reset by the force of the abutment spring.

[0021] Preferably, the driving device comprises a hydraulic cylinder, and guide devices are arranged on both sides of the hydraulic cylinder.

One end of the T-slot is opened. A T-slot 311 cooperating with the T-slot is arranged on the cutter, so that the T-slot can be inserted into the T-slot from the opening at one end of the T-slot, so that the T-slot is arranged in the T-slot.

[0043] In order to make the driving device drive the mounting plate to move more stably, a guide device 5 is arranged on both sides of the driving group device, and the guide device includes a guide sleeve 51 and a guide column 52.

[0045] like Figures 5 to 7 As shown, there is no fixing hole at the bottom of the fixed plate 61, but a plurality of piston cavities 612 are arranged at the bottom of the fixed plate. In this embodiment, three piston cavities are arranged, and a guide column 621 is arranged on the abutment plate 62. A piston head 625 cooperating with the piston cavity is arranged at the end of the guide column. The piston head can slide in the piston cavity, and the piston head is sealed with the side wall of the piston cavity, so that a sealed cavity is formed between the piston cavity and the piston head, and hydraulic oil is arranged in the sealed cavity. An abutment spring 63 is sleeved on the guide column; an oil cavity 613 is arranged above the inside of the fixed plate, and a vent hole communicating with the oil cavity is arranged on the top of the fixed plate, and the vent hole is used to balance the air pressure in the oil cavity.
