[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 3 As shown in this embodiment, a micro-motion hopper includes a cylinder body 1, a base 2, and an isolation net 3. The isolation net 3 is installed on the upper end of the cylinder body 1. A cylinder cover 4 is placed on the cylinder body 1 and presses against the isolation net 3. A negative pressure suction pipe 5 is installed on the cylinder cover 4. A material discharge inclined pipe 6 is installed inside the base 2. The upper end of the material discharge inclined pipe 6 is connected to the lower end of the cylinder body 1. A movable tongue 7 is provided at the lower end of the material discharge inclined pipe 6. A swing rod 8 is rotatably connected to the base 2. One end of the swing rod 8 is connected to a weighing hammer 9.

[0019] After the material enters the cylinder 1, it falls downwards. The negative pressure suction pipe 5 draws air, adsorbing the gas containing moisture upwards. The dry material falls into the inclined discharge pipe 6. To prevent the material from being sucked away, an isolation net 3 is added to block the material inside the cylinder 1. When the material is not yet sufficient, the movable tongue 7 closes the lower end of the inclined discharge pipe 6. When the weight reaches the weight of the weighing hammer 9, the weighing hammer 9 swings, the movable tongue 7 opens, and all the current material is collected at once.

[0020] A screw 10 is hinged to the upper edge of the cylinder body 1, and a handwheel 11 is threaded to the outer end of the screw 10. A clamping buckle 12 is fixed to the edge of the cylinder cover 4. After the screw 10 is inserted into the clamping buckle 12, the handwheel 11 is screwed to fix it. When replacing the isolation net 3, the cylinder cover 4 can be opened by manually screwing the handwheel 11 and removing the screw 10 from the clamping buckle 12. After replacing the isolation net 3, the screw 10 is pushed back into the clamping buckle 12 and the handwheel 11 is screwed to lock it. It is convenient and quick.

[0021] A feed pipe 13 is connected to the outside of the cylinder body 1. The feed pipe 13 is connected to the inside of the cylinder body 1, and material is introduced into the cylinder body 1 through the feed pipe 13.

[0022] A sealing ring 14 is provided at the upper end of the isolation net 3. The inner edge of the sealing ring 14 is pressed against the upper edge of the isolation net 3, and the outer edge of the sealing ring 14 is pressed against the upper end of the cylinder body 1. Under the action of the sealing ring 14, the negative pressure capacity is improved, the ventilation effect is better, and the material is effectively prevented from leaking out from the edge of the isolation net 3.

[0023] A proximity switch 15 is fixed to the outside of the base 2. An eccentric wheel 16 is fixed to the end of the swing arm 8 away from the weighing hammer 9. The proximity switch 15 senses the position of the eccentric wheel 16. During the downward movement of the weighing hammer 9, the eccentric wheel 16 is pulled to rotate. After touching the proximity switch 15, the movable tongue 7 is closed to prevent materials exceeding the weight from continuing to flow out.

[0024] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
