Oil seed roasting machine sealing pan cover and pan cover opening and closing device

Abstract

The invention relates to an oil seed roasting machine sealing pan cover and pan cover opening and closing device which comprises a pan cover, a feed pipe, an articulated four-link mechanism, a manual operating rod, a transmission shaft, a crank shaft push rod mechanism and an automatic pan cover opening electric control part, wherein a hole where the feed pipe is mounted in a penetrating manner is formed in the center of the pan cover; a bearing is mounted between the feed pipe and the center hole of the pan cover; pan cover hinged shafts are symmetrically mounted on the two sides of the feed pipe; the two ends of the hinged shafts are movably connected with the articulated four-link mechanism symmetrically arranged on the two sides of the pan cover respectively; the transmission shaft connected with the articulated four-link mechanism is arranged at the lower part of the pan cover; the manual operating rod is mounted on the transmission shaft; and the transmission shaft is connected with the crank shaft push rod mechanism arranged at the lower part. According to the device, the pan cover adopts a movable sealed structure, and can be clung to a roller pan port to automatically seal the pan port by the articulated four-link mechanism; the practical effects of flexible pan cover opening and closing, and convenient feeding and discharging can be realized; the pan cover can be opened and closed manually or opened automatically; manual operation and automatic operation do not affect each other; and the device is simple and flexible to operate and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of oil processing equipment, in particular to a closed pot cover and a pot cover opening and closing device for an oil seed frying machine suitable for horizontal drum frying pans. Background technique [0002] In the prior art, most of the processing of vegetable oil adopts the process of hot pressing to produce vegetable oil, and the oil plants need to be fried and processed before the vegetable oil is extracted. And the commonly used horizontal drum frying machine, whether it is electric heating or heating with coal or firewood, does not add a pot cover at the mouth of the drum frying pan, but adopts an open frying method. The disadvantages of this kind of open-top frying are: (1) because the heat in the pot is quickly lost to the outside of the pot, the frying time is long and the energy consumption is large; (2) when the seeds in the pot are turned, dust and smoke are discharged out of the pot, pollutin...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of open-top frying are: (1) because the heat in the pot is quickly lost to the outside of the pot, the frying time is long and the energy consumption is large; (2) when the seeds in the pot are turned, dust and smoke are discharged out of the pot, polluting Working environment, causing physical damage to workers

At present, there are also some frying machines on the market that use closed frying materials. The mouth of the drum frying pan adopts a fixed closed type. When unloading, it is necessary to loosen the screw to open the baffle for unloading, which is inconvenient to operate, and at the same time, the entire pot mouth cannot be opened because of the small unloading hole, so the unloading speed is slow, the unloading is not complete, and it is difficult Defects in realizing automatic unloading
