Description
Technical Field
[0001] The utility model relates to the field of grain circulation equipment, in particular to a device for safely disassembling a flat grain blocking plate of a granary door. Background Art
[0002] When the bulk grain stored in the granary is unloaded, the grain outlet is opened first to allow the grain to flow to the conveying machinery due to the high grain pile, and then the conveying machinery is sent to the grain transport vehicle. When the grain stops flowing, the loading and unloading personnel can remove the flat grain baffles in the middle and upper parts that have been discharged, and generally 3-4 pieces are left. Each flat grain baffle is generally 30-40 cm high and weighs about 30 kg. When installed, the flat grain baffle is pressed against the wall at the door of the warehouse by the lateral pressure of the grain; due to the lateral pressure of the grain, it is difficult to remove it manually, and it is generally removed with a crowbar. During removal, the gap between the flat grain baffles is very small, and it is easy to damage the flat grain baffles. Moreover, when removing and prying, the flat grain baffles collide with the warehouse wall, which is easy to cause damage to the wall surface and moisture-proof layer. More importantly, when the grain baffle is removed with a crowbar, the grain flow is difficult to control, and the grain flow and the flat grain baffle are carried out together. Generally, there are personnel in the warehouse to cooperate with the removal personnel outside. Utility Model Content

One end of the pin shaft is a flat head and the other end is provided with a through hole. The cotter pin passes through the through hole to fasten the installed pin shaft. Although this arrangement is simple, it is very practical.
[0030] In order to enable those skilled in the art to better understand the present invention, its basic working principle is briefly described as follows:
[0031] The reason for using hydraulic jacks is that, firstly, the technology of such small equipment is very mature, and the quality of such products on the market is also relatively good, and secondly, it is relatively easy to operate. When using this type of safe disassembly device for flat grain baffles of granary gates, each part is installed in place, and the heads 1.2 of the two bolts 1 installed on the flat grain baffles 22 of the granary gate corresponding to the grain outlet position are first pulled out to place them in the transverse grooves 2 of the support body 4; the operator steps on the extended base 8 with his feet to fix the hydraulic jack, and at the same time slowly presses down the handle 11 to slowly rise the large piston rod 15, thereby driving the lifting body to slowly rise, the support body 4 and the heads 1.2 of its two bolts 1 also slowly rise, and correspondingly the flat grain baffle 22 slowly rises under the drive of the screw 1.1; the gap between the flat grain baffle 22 and the next flat grain baffle 22 gradually increases, and grain gradually flows out of the gap; when grain no longer flows out, the flat grain baffle 22 can be easily removed. According to the same method, the remaining flat grain blocking plates 22 at the bottom are taken out one by one, thereby completing the safe disassembly of the flat grain blocking plates 22 of the granary door.
