[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] A fully sealed automatic hazardous waste feeding device includes a sealed channel 1 with three rotating shafts 2 movably installed at both ends of the sealed channel 1. One rotating shaft 2 is located at one end of the sealed channel 1, and two rotating shafts 2 are located at the other end of the sealed channel 1. A conveyor belt 3 is installed on the three rotating shafts 2. One of the rotating shafts 2 is connected to a transmission rod 4. A drive gear 5 is installed on the transmission rod 4. A transmission shaft 6 is located above the drive gear 5. A driven gear 7 is installed on the transmission shaft 6. The drive gear 5 and the driven gear 7 mesh. A crushing device 8 is connected to one side of the transmission shaft 6.

[0025] like Figures 1-6 As shown: During the operation, the operator puts the hazardous waste to be processed into the equipment through the feed port 801. The waste first enters the crushing device 8, where it is subjected to strong shearing and crushing to ensure that large pieces of waste are broken down into small pieces. After being crushed, the waste falls naturally onto the conveyor belt 3 below under the action of gravity, and is then transported to the discharge port 11 by the conveyor belt 3.

[0026] Preferably, the crushing device 8 includes a feed inlet 801 installed on the upper surface of the sealed channel 1. A pair of rotor shafts 802 are provided at the lower end of the feed inlet 801. Multiple blades 803 are provided on both rotor shafts 802. A spur gear 804 is provided at one end of both rotor shafts 802. One of the spur gears 804 is connected to the drive shaft 6.

[0027] Preferably, the two rotor shafts 802 rotate in opposite directions.

[0028] like Figures 1-6 As shown: After the waste is fed into the feed inlet 801, it is crushed. The output of the drive motor 9 drives the transmission rod 4 to rotate. The rotation of the transmission rod 4 achieves two functions simultaneously through the linkage mechanism: it drives the rotating shaft 2 to rotate, drives the conveyor belt 3 to start working, and drives the drive gear 5 to rotate synchronously. The drive gear 5 meshes with the driven gear 7, driving the driven gear 7 to rotate. The driven gear 7 is fixed on the transmission shaft 6, driving the transmission shaft 6 to rotate. The transmission shaft 6 drives one of the rotor shafts 802 and the spur gear 804 on it to rotate. The spur gear 804 meshes with the other spur gear 804. Through the meshing transmission of the spur gear 804, the second rotor shaft 802 is driven to rotate in the opposite direction. The two rotor shafts 802 maintain relative rotational motion. The blades 803 installed on the rotor shafts 802 then perform relative shearing motion. The incoming waste is effectively crushed under the shearing action of the blades 803. The crushed waste naturally falls onto the already running conveyor belt 3.

[0029] The drive motor 9 drives the conveyor belt 3 and the crushing device 8 at the same time. This integrated drive system achieves a high-efficiency operation mode of one machine with two drives through mechanical design, saving costs, reducing equipment failure rate and improving work efficiency.

[0030] Preferably, a drive motor 9 is installed on one side of the sealed channel 1, and the output end of the drive motor 9 is connected to the transmission rod 4.

[0031] Preferably, the surface of the conveyor belt 3 is provided with multiple blocks 10.

[0032] like Figures 1-6 As shown: When transporting the cut waste, due to the friction of the conveyor belt 3 itself, plus the stop 10 set on the conveyor belt 3, the waste will not fall off the conveyor belt during the transportation process.

[0033] Preferably, the bottom of one end of the sealed channel 1 is provided with a discharge port 11, a shaft 12 is installed in the middle of the discharge port 11, a flexible rotating plate 13 is movably installed on the shaft 12, a torsion spring 14 is installed at both ends of the flexible rotating plate 13, the other end of the torsion spring 14 is connected to the inner side wall of the discharge port 11, and a column rod 15 is provided at the upper end of the flexible rotating plate 13, the upper surface of the column rod 15 is higher than the lower surface of the stop block 10.

[0034] like Figures 1-6 As shown: the sheared waste is conveyed to the discharge port 11 via conveyor belt 3. When the stop block 10 on the conveyor belt 3 moves to the position of the column 15, it pushes the column 15 to rotate, causing the flexible rotating plate 13 to rotate around the shaft 12. At the same time, the torsion spring 14 undergoes elastic deformation. After the stop block 10 leaves, the torsion spring 14 releases its elastic potential energy, driving the flexible rotating plate 13 and the column 15 to spring back to the initial position. As the subsequent stop block 10 periodically passes the column 15, the above process is repeated, causing the flexible rotating plate 13 to continuously swing back and forth, thereby effectively preventing waste from accumulating and blocking at the discharge port 11. During the feeding process, the swing of the flexible rotating plate 13 can prevent material blockage. Since the flexible rotating plate 13 is made of a flexible material, it can bend to a certain extent but will not bend completely. Thus, the flexible rotating plate 13 can swing moderately within the discharge port 11, playing a role in preventing blockage.

[0035] Preferably, the upper end of the feed inlet 801 is conical, and a notch is provided on one side of the feed inlet 801.

[0036] The working principle of this utility model is as follows: After the waste is put into the feed inlet 801, the waste is crushed; the output end of the drive motor 9 drives the transmission rod 4 to rotate. The rotation of the transmission rod 4 achieves two functions simultaneously through the linkage mechanism, driving the rotating shaft 2 to rotate, driving the conveyor belt 3 to start working, and simultaneously driving the drive gear 5 to rotate synchronously. The drive gear 5 meshes with the driven gear 7, driving the driven gear 7 to rotate. The driven gear 7 is fixed on the transmission shaft 6, driving the transmission shaft 6 to rotate. The transmission shaft 6 drives one of the rotor shafts 802 and the spur gear 804 on it to rotate. The spur gear 804 meshes with the other spur gear 804. Through the meshing transmission of the spur gear 804, the second rotor shaft 802 is driven to rotate in the opposite direction. The two rotor shafts 802 maintain relative rotational motion. The blades 803 installed on the rotor shafts 802 then perform relative shearing motion. The waste entering is effectively crushed under the shearing action of the blades 803. The crushed waste naturally falls onto the already running conveyor belt 3.

[0037] The drive motor 9 drives the conveyor belt 3 and the crushing device 8 at the same time. This integrated drive system achieves a high-efficiency operation mode of one machine with two drives through mechanical design, saving costs, reducing equipment failure rate and improving work efficiency.

[0038] The sheared waste is conveyed to the discharge port 11 via the conveyor belt 3. When the stop block 10 on the conveyor belt 3 moves to the position of the column 15, it pushes the column 15 to rotate, causing the flexible rotating plate 13 to rotate around the shaft 12. At the same time, the torsion spring 14 undergoes elastic deformation. After the stop block 10 leaves, the torsion spring 14 releases its elastic potential energy, driving the flexible rotating plate 13 and the column 15 to spring back to the initial position. As the subsequent stop block 10 periodically passes the column 15, the above process is repeated, causing the flexible rotating plate 13 to continuously swing back and forth, thereby effectively preventing waste from accumulating and blocking at the discharge port 11.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
