[0028] A protective device 2 is provided on the top of the collection box body 101, and the protective device 2 includes a fixed rod 201, the bottom of the fixed rod 201 is fixedly connected to the top of the collection box body 101, the top of the fixed rod 201 is fixedly connected to a telescopic rod 202, the telescopic end of the telescopic rod 202 is fixedly connected to a mounting plate 206, and the top of the mounting plate 206 is penetrated by a mounting block 205.

[0029] A return spring 204 is fixedly connected to the bottom of the mounting block 205, and one end of the return spring 204 away from the mounting block 205 is fixedly connected to the top of the fixing rod 201. The initial state of the return spring 204 is a relaxed state, thereby reducing the direct impact on the collection box body 101, protecting its structure and internal equipment, and avoiding damage and failure.

[0030] A hydraulic bin 208 is provided at the bottom of the mounting plate 206, one end of the hydraulic bin 208 is connected to a positioning rod 207 through a piston sliding connection, and the other end of the hydraulic bin 208 is connected to a hydraulic rod 209 through a piston sliding connection. An electric telescopic rod 211 is fixedly connected to the top of the collection box body 101, and the telescopic end of the electric telescopic rod 211 is fixedly connected to a fixed plate 212, which effectively reduces the impact on the collection box body 101, reduces the possibility of damage, and extends the service life of the equipment.

[0031] A switch 210 is provided on the side of the electric telescopic rod 211, and the control end of the switch 210 is located on the movement track of the hydraulic rod 209. A spring 203 is fixedly connected to the bottom of the mounting plate 206, and one end of the spring 203 away from the mounting plate 206 is fixedly connected to the top of the fixed rod 201, thereby avoiding damage or performance degradation of the equipment during long-term use, thereby extending the service life of the equipment and components and reducing maintenance costs.

[0032] The number of springs 203 is set to be several, two in a group, and symmetrical with each other along the vertical center axis of the collection box body 101. The initial state of the spring 203 is a relaxed state, which can reduce the frequency of replacing parts or repairing equipment and improve the reliability and stability of the system.

[0033] The number of electric telescopic rods 211 is set to be several, two in a group, and symmetrical with each other along the vertical center axis of the collection box body 101. A positioning plate 213 is fixedly connected to the top of the mounting block 205, avoiding possible equipment damage or failure, reducing potential safety risks caused by equipment failure, and ensuring the safety of operators and equipment.

[0034] The number of telescopic rods 202 is set to be several, two in a group, and symmetrical with each other along the vertical center axis of the collection box body 101. The vibration force is offset by generating a reaction force opposite to the vibration direction, further reducing the damage caused by the impact and protecting the overall structure of the collection box body.

[0035] A specific application of this embodiment is: when an external force hits the collection box body 101, the impact force causes the mounting plate 206 to be squeezed and displaced inward, and the impact force is transferred to the mounting plate 206 to reduce the direct impact on the collection box body 101, thereby protecting the structure and internal equipment of the collection box body 101. The telescopic rod 202 can absorb and disperse a part of the impact energy to reduce the impact on the collection box body 101. The mounting plate 206 is displaced inward to cause the telescopic rod 202 to contract, and then the mounting plate 206 is reset by the elastic force of the spring 203, thereby protecting the collection box body 101. The spring 203 is compressed to convert the vibration energy into elastic potential energy. The spring 203 offsets the vibration force by generating a reaction force opposite to the vibration direction, thereby protecting the collection box body 101 and effectively reducing the impact. The damage caused by the piston is prevented, and the overall structure of the collection box body 101 is protected. When the mounting plate 206 moves downward, the positioning rod 207 is driven to move downward. The positioning rod 207 moves downward to squeeze a piston inside the hydraulic chamber 208, and then the piston pushes the liquid inside the hydraulic chamber 208. The liquid flow inside the hydraulic chamber 208 pushes another piston inside it to move. During the displacement process, the piston squeezes the hydraulic rod 209 fixed to it, so that the hydraulic rod 209 pops out and squeezes the switch 210. After the switch 210 is squeezed, the electric telescopic rod 211 is started. The electric telescopic rod 211 starts to stretch and pushes the fixed plate 212 fixed at its telescopic end to move upward to resist the object being pressed on the top of the positioning plate 213, thereby achieving the effect of lifting the object, preventing the object from excessively squeezing the spring 203 and other objects, and increasing the service life of the device.
