Description
Technical field
The utility model relates to a kind of wind drawing-in device that closes, and is used for equipment feedings such as cooling vessel, stabiliser, belongs to the grain feed field of mechanical technique.
Background technology
The drawing-in device of equipment such as existing cooling vessel, stabiliser all adopts the vane type air sealer, and material leans on the mode of self gravitation to enter into air sealer by upstream equipment.One S. A. is arranged in the air sealer circular cavity, be connected with some blades around the S. A., S. A. is rotated by driven by motor, and the blade on the S. A. is rotation synchronously also, and material is patted in the feeding warehouse.
There is following technical matters in existing drawing-in device: (1) blade is patted the material of feeding owing to motional inertia, does not drop on the center of warehouse after feeding, evenly brings difficulty for follow-up spreading; (2) whole drawing-in device complex structure is made and assembly precision requires height, and cost is also higher; (3) the materials flow instability of Gong Geiing brings certain difficulty for the adjustment of downstream spreading device; (4) need independent motor driver, energy consumption cost increases; (5) wearing and tearing of blade are comparatively serious, not easy care.
The utility model content
For overcoming problems of the prior art, the utility model provides a kind of wind drawing-in device that closes, and simple in structure, easy to manufacture, cost is low, and feeding is evenly reliable.
For solving above technical matters, a kind of wind drawing-in device that closes provided by the utility model, comprise cylinder, elephant trunk, cylinder, guide rod and spreading awl, described cylinder supports on the cover board, the lower end oblique cutting of described elephant trunk is gone in the barrel of described cylinder, the upper port of described cylinder is provided with end cap, described cylinder is installed on the described end cap, the piston rod of described cylinder stretches in the described cylinder and by coupler and is connected with described guide rod, the lower end of described guide rod is connected with described spreading awl, and the periphery of the circular conical surface of described spreading awl covers on the lower port of described cylinder.
With respect to prior art, the utility model has been obtained following beneficial effect: the spreading awl is connected the guide rod below, and guide rod is connected on the piston rod of cylinder, and the flexible of cylinder piston rod will affect spreading awl up-and-down movement.The spreading awl is blocked the lower port of cylinder, and material injects cylinder from elephant trunk, when the height of materials in the cylinder gathers certain altitude, the cylinder action, its piston rod elongation, the spreading awl leaves the lower port of cylinder, and material evenly flows out from the circular conical surface of spreading awl; When the material in the cylinder dropped to certain altitude, cylinder moved once more, and its piston rod shrinks, and the spreading awl rises, and covers the lower port of cylinder again, enters next cycle.
As improvement of the present utility model, described cylinder bottom is equipped with support, and the two end supports of described support is on the inwall of described cylinder, and the middle part of described support is provided with leader casing, and described guide rod is inserted in the described leader casing.The support of cylinder bottom and leader casing play guide rod and help and positioning action, guarantee that the position after the action of spreading awl is accurate.
As further improvement of the utility model, be provided with the level detector that detects height of materials in the cylinder in the described cylinder, the end cap of described cylinder upper port is provided with the electromagnetic valve of the described cylinder action of control, and control system receives the signal of described level detector and controls the action of described electromagnetic valve.Material enters inner barrel by elephant trunk, build up, until material contact level detector, level detector provides asserts signal, triggers slug relay and gets, delayed time some seconds, allow material continue to be accumulate to the cylindrical shell optimum height, the triggering electromagnetic valve gets electric, the cylinder action, promote the spreading awl downwards, material promptly scatters to device interior along the awl cap of spreading awl and the place, slit of barrel; Along with material scatters, the inner barrel height of materials descends, and the level detector blade rotates again, and level detector resets, trigger the electromagnetic valve dead electricity, the piston rod of cylinder shrinks, and the spreading awl up resets airtight with cylindrical shell, material begins accumulation once more, and so circulation has realized closing wind feeding function repeatedly.
Description of drawings
Fig. 1 closes the structural representation of wind drawing-in device for the utility model.
Fig. 2 is the left view of Fig. 1.
Among the figure: 1 cylinder, 2 elephant trunks, 3 coupler, 4 cover plates, 5 cylinders, 6 guide rods, 7 supports, 7a leader casing, 8 spreadings awl, 9 electromagnetic valves, 10 level detectors.
The specific embodiment
As shown in Figure 1, the wind drawing-in device that closes of the present utility model comprises cylinder 5, elephant trunk 2, cylinder 1, guide rod 6 and spreading awl 8, cylinder 5 is supported on the cover plate 4, the lower end oblique cutting of elephant trunk 2 is gone in the barrel of cylinder 5, the upper port of cylinder 5 is provided with end cap, and cylinder 1 is installed on the end cap, and the piston rod of cylinder 1 stretches in the cylinder 5 and by coupler 3 and is connected with guide rod 6, the lower end of guide rod 6 is connected with spreading awl 8, and the periphery of the circular conical surface of spreading awl 8 covers on the lower port of cylinder 5.Cylinder 5 bottoms are equipped with support 7, and the two end supports of support 7 is on the inwall of cylinder 5, and the middle part of support 7 is provided with leader casing 7a, and guide rod 6 is inserted among the leader casing 7a.
