The technical scheme in the invention for solving the technical problem is: a kind of screw feeder with outgate sealing, comprise that transfer passage and coupling are set in the spiral promoting shaft in transfer passage, and drive motor, one end upside of transfer passage arranges inlet point, the other end downside of transfer passage arranges discharging opening, at discharging opening place, be provided with crowded testing agency, described crowded testing agency comprises an outgate that is arranged on transfer passage sidewall, in outgate inner side, arrange elastic top pressure device and with the on-off element of elastic top pressure device cooperating.
On described outgate, be provided with adapter plate, in elastic top pressure device bottom, be provided with portable plate, described elastic top pressure device is on portable plate, to be installed with push shaft, in adapter plate bottom, axle sleeve is installed, described push shaft coordinates installation with axle sleeve, on push shaft, be provided with the jump ring coming off for anti-thrust shaft, described axle sleeve outside is set with retracing spring, retracing spring one end is connected and fixed plate, the other end connects portable plate, portable plate and and adapter plate between outer rim be also fixed with annular caulking gum body.
Described on-off element is pressure switch or is pressure sensor.
Described outgate and the discharging opening that is positioned at transfer passage sidewall is symmetrical arranged.
Described drive motor and spiral promoting shaft input end be through chain, belt or gear transmission.
Beneficial effect: the utility model is simple in structure, cost of manufacture is low, easy to use, owing to being provided with crowded testing agency at screw feeder discharging opening place, in convey materials process, at the equipment of next flow process, break down, while causing feed blocking, this crowded testing agency can detect in time blocked state in machine and also report to the police and send signal, makes to stop feed with the device that delivers from godown of feeding machine cooperating, avoids causing screw feeder fault and material to shed.Save raw material, guaranteed clean, the health of operating environment, and reduced the fault rate of equipment, be very suitable for promotion and implementation in flour conveying industries.
Accompanying drawing explanation
Fig. 1 is that the utility model is with the screw feeder structural representation of outgate sealing;
Fig. 2 is the outgate structure for amplifying schematic diagram in Fig. 1.
Number in the figure, 1 is spiral promoting shaft input end, and 2 is transfer passage, and 3 is sealing adapter plate, and 4 is closing plate, 5 is spiral promoting shaft; 6 is adapter plate, and 7 is axle sleeve, and 8 is push shaft, and 9 is on-off element, and 10 is caulking gum body; 11 is jump ring, and 12 is portable plate, and 13 is outgate, and 14 is inlet point, and 15 is discharging opening; 16 is retracing spring, and 17 is seal closure.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.
Embodiment 1: referring to Fig. 1, Fig. 2, a kind of screw feeder with outgate sealing, comprise that transfer passage 2 and coupling are set in the spiral promoting shaft 5 in transfer passage 2, and drive motor, one end upside of transfer passage 2 arranges inlet point 14, the other end downside of transfer passage 2 arranges discharging opening 15, at discharging opening, 15 places are provided with crowded testing agency, described crowded testing agency comprises an outgate 13 that is arranged on transfer passage 2 sidewalls and discharging opening symmetric position, outgate and discharging opening are symmetrical arranged, can monitor feed blocking state in machine in the very first time, and and alarm send signal.In outgate 13 inner sides, arrange elastic top pressure device and with the on-off element 9 of elastic top pressure device cooperating, described on-off element 9 is positioned at the roof inner side of outgate seal closure 17, described on-off element 9 can or be pressure sensor for pressure switch.
On outgate 13, be provided with adapter plate 6, in elastic top pressure device bottom, be provided with portable plate 12, described elastic top pressure device is on portable plate 12, to be installed with push shaft 8, in adapter plate 6 bottoms, axle sleeve 7 is installed, described push shaft 8 coordinates installation with axle sleeve 7, and the position that is positioned at axle sleeve 7 tops on push shaft 8 is provided with jump ring 11, jump ring 11 coordinates with axle sleeve 7 scope that defines push shaft down sliding, and anti-thrust shaft 7 and portable plate 12 come off.Described axle sleeve 7 outsides are set with retracing spring 16, and retracing spring 16 one end are connected and fixed plate 6, and the other end connects portable plate 12, in machine, during feed blocking, under the promotion of portable plate material pressure in machine, overcome spring force, drive push shaft 8 integral body to move up, push shaft 8 pull switch element switches.Outer rim between portable plate 12 and adapter plate 6 is also fixed with annular caulking gum body 10.Caulking gum body 10 has guaranteed the leak tightness of crowded testing agency, detect sensitiveer, improved in addition the vertical mobile stability of portable plate, avoided portable plate only to rely on the pulling force of push shaft to support, in machine, flour pressure increases while upwards promoting portable plate, there is periphery discontinuity in portable plate, the phenomenon tilting.Further guaranteed the stability of equipment work.
