The device is simple in structure and low in cost; design is reasonable, and installation is convenient; when the electric push rod linearly reciprocates, all action points of the connecting rod mechanism are driven, and all the valve plates are opened and closed at the same time. A remote control system can be added to remotely control the electric shutter.

Description

Technical Field

[0001] The utility model belongs to a corn seed drying device, in particular to an electric shutter. Background Art

[0002] With the competition and rapid development of the seed industry, seed companies have high requirements for the performance parameters of seed processing equipment to ensure that the seeds after selection and processing reach the first-class improved varieties. Because high-quality seeds can achieve excellent sowing, increase yields, increase farmers' income, and also promote seed sales. In addition, seed companies also need to reduce various costs to improve their economic benefits. First, consider reducing labor costs and using machines instead of people; second, consider shortening the processing cycle, requiring the use of new processing technology and reducing the operation and adjustment time of equipment, improving the degree of equipment automation, and realizing remote control.

[0003] For corn seed production, mechanical sowing, tassel removal by tassel extractor, and mechanical harvesting and peeling have replaced the original manual operation. After the corn ears are harvested, they are transported to the processing plant and a new two-stage drying process is adopted to shorten the processing cycle. First, the ears are dried to reduce their moisture content. When the appropriate moisture content is reached, threshing is carried out, at which time the threshing rate is the highest and the breakage rate is the lowest. The moisture content of the kernels just after threshing is higher than the safe storage moisture content, and they cannot be immediately selected, coated, and packaged for storage in the warehouse. The moisture content needs to be further reduced. At this time, the threshed kernels are dried again. The working principle of the kernel dryer is that the seeds make a folding and reverse motion in the dryer and keep rolling and turning, contacting hot air from all directions, so that the seeds are heated and evaporate the internal moisture, and the moisture is carried to the exhaust port on the top of the dryer with the hot air flow. Originally, manual shutters were installed at the exhaust port. Due to the large size of the dryer and the total height of more than ten meters, it was inconvenient to adjust the shutters every time. In order to facilitate operation, realize automatic control, and remotely open and close the shutters automatically, a special electric shutter was developed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an electric shutter, which includes a frame, an electric push rod, a connecting rod, a valve plate and an axle seat; the electric push rod is fixed on the outside of the frame, and four groups of valve plates are arranged inside the frame, a rotating shaft is fixed at the center position of the valve plate, and the rotating shaft of the valve plate is movably connected to the axle seat at the corresponding position outside the frame; the connecting rod is movably connected through connecting rod action point II, connecting rod action point III, connecting rod action point IV, and connecting rod action point V, the connecting rod is movably connected to the electric push rod through connecting rod action point I, and connecting rod action point II, connecting rod action point III, connecting rod action point IV, and connecting rod action point V are respectively fixed on the same side of the valve plate at the same position.

[0005] Compared with the prior art, the utility model has the following advantages: simple structure, low cost; reasonable design, convenient installation; when the electric push rod reciprocates in linear motion, it drives the action points of the connecting rod mechanism to open and close all valve plates at the same time. A remote control system can be added to remotely control the electric blinds. BRIEF DESCRIPTION OF THE DRAWINGS
