Technical Field

[0001] The utility model relates to the technical field of industrial cameras, in particular to an extraction device direct feeding device. Background Art

[0002] The feeding device is one of the indispensable devices in the operation of the extraction device. Under the operation of the staff, the material can be directly fed into the extraction device through the device. The reflux pump at the top of the deweighting tower of the post-fractionation unit can transport the material to the inner side of the extraction device through the device. In view of this, the traditional device is not perfect enough and there is no facility for the device to buffer the material. A direct feeding device for the extraction device can provide convenience for the staff.

[0003] Existing feeding devices usually need to transport materials to the intermediate tank area for storage when the feeding speed is fast and the feeding volume is large, and then transport them to the inside of the extraction device. The device consumes high power and has great safety hazards. Utility Model Content

[0004] The utility model aims to provide a direct feeding device for an extraction device, which can solve the technical problems of high power consumption and great safety hazards of the device in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a direct feeding device for an extraction device, comprising a feeding hopper, a feeding pipe is installed through the bottom of the feeding hopper;

[0006] A buffer tank is installed on the outside of the feed pipe, a discharge pipe is installed through the bottom of the buffer tank, a cylinder is installed on the outside of the discharge pipe, two guide rods are installed between the inner side of the top wall and the inner side of the bottom wall of the cylinder, two springs are installed on the inner side of the top wall of the cylinder, and the two springs are respectively located on the outside of the two guide rods, and a circular plate is installed on the bottom of the spring, and the circular plate is located on the outside of the guide rod.

[0007] Preferably, two through holes are penetrated through the outer side of the discharge pipe, a connecting rod is installed on the side where the two circular plates are close to each other, and the connecting rod is penetrated and installed on the inner side of the through hole, and a ring is installed on the end where the two connecting rods are close to each other.

[0008] Preferably, a protective tube is installed at the bottom of the ring.

[0009] Preferably, a plastic bag is installed on the top of the ring, and one end of the plastic bag is installed on the outside of the feeding pipe.

[0010] Preferably, a motor is installed on the outside of the feed pipe, the output end of the motor is installed inside the feed pipe through a bearing, a solid block is installed on the inside of the feed pipe, and a movable groove is opened on the inside of the solid block.

[0011] Preferably, a first gear is installed on the outside of the motor output end, and the first gear is located on the inner side of the movable groove. A transmission rod is installed through the bottom of the solid block, and two other gears are installed on the outside of the transmission rod. The gear close to the top of the transmission rod is the second gear, and the gear close to the bottom is the third gear. The second gear is meshed with the first gear.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is equipped with a plastic bag. When the feeding speed is too fast and the feeding amount is large, the material will cause pressure on the plastic bag. The plastic bag expands under the action of the material, so that the material drives the plastic bag to accumulate on the inner side of the buffer tank, and the plastic bag pulls the ring upward. The ring moves upward under the action of external force, and the ring drives the circular plate upward through the connecting rod, so that the circular plate moves upward along the outer side of the guide rod on the inner side of the cylinder. The circular plate squeezes the spring and is compressed and deformed. The ring drives the protective tube upward at the same time, so that the protective tube is located at the position of the through hole to prevent the material from entering the inner side of the cylinder from the through hole. When the feeding speed is reduced and the feeding amount is small, the spring uses its own elastic force to drive the ring downward through the connecting rod, so that the ring pulls the plastic bag to a vertical state, so that the device can provide a buffering effect as the feeding amount increases, reduce the power consumption of the device, and improve safety.

[0015] 2. The utility model is installed with a motor. The staff starts the motor to rotate the output end of the motor. The motor output end drives the outer gear to rotate with itself as the center of the circle, so that the gear utilizes the meshing effect with the gear near the top of the transmission rod to drive it to rotate. The gear near the top of the transmission rod drives the transmission rod to rotate, so that the transmission rod drives the gear near the bottom to rotate with itself as the center of the circle. The gear near the bottom of the transmission rod utilizes the meshing effect with the gear ring to drive the gear ring to rotate with the bearing as the center of the circle, so that the gear ring drives the fan-shaped plate at the bottom to rotate. When the fan-shaped plate completely overlaps with the fan-shaped plate inside the feed pipe, the speed of the material passing through the feed pipe is the maximum. When there is no overlap at all, the feed pipe is sealed, which is convenient for the staff to change the overlap of the two fan-shaped plates and thus change the feeding speed of the feed pipe.
