Abstract

The utility model relates to a seed hulling machine for hulling and processing a plurality of oil crop seeds, which comprises a machine frame and a feed hopper above the machine frame, wherein a machine enclosure is installed below the feed hopper, an upper cover is configured on the upper end of the machine enclosure, a material throwing tray is installed in a machine cover, a radial passage is arranged on the material throwing tray, an impact retaining ring is installed in the periphery of the material throwing tray, the material throwing tray is connected with a variable speed driving device via a vertical shaft assembly, and a discharge port is arranged below the machine enclosure. The utility model has the advantages of simple structure, reliable performance, wide flexibility of operation, high hulling yield, low fines content and good quality. The utility model has a good hulling effect particularly flax seeds with a large hulling difficulty.

Description

The seed hulling machine

The utility model relates to a kind of being used for the shell equipment of processing of seeds such as oil crops such as rape, soybean, castor-oil plant, flax, sunflower, perillaseed, safflower.

The seed of oil crops is produced grease after shelling, can not only improve the purity and the quality of grease, and can improve the quality of grouts after the oil expression, make it become a kind of good protein feed source, and, contain the seed cot such as the proteins in flax seeds of special composition for some, flax glue is produced with shell in the shelling back can save the energy 50% than band shell glue, also can make the cot of its separation obtain reasonable use.At present, had the seed hulling machine of multiple different structure and function, yet, the structure of these hulling machines is mostly comparatively complicated, function is then comparatively single, only can process the oil crops seed of single variety, and yet there are no the report of relevant hulling device for linseed.

The purpose of this utility model is to design that a kind of structure is comparatively simple, the wider seed hulling machine of processing applicability.

The purpose of this utility model is realized by following scheme: include frame 1, the frame top is installed into hopper 3, casing 14 is installed in the below of feed hopper, casing upper end configuration loam cake 5, the casing internal upper part is equipped with batch mixing pan 6, and batch mixing pan is provided with the radial passage, in the external circumferential of batch mixing pan bump back-up ring 7 is installed, batch mixing pan links by a vertical shaft assembly 9 and a speed-changing driving device 12, and the below of casing offers discharging opening 11.

Working mechanism of the present utility model is: seed falls into batch mixing pan through feed hopper, batch mixing pan is rotation at a high speed under the drive of vertical shaft assembly, at this moment, seed rotates with batch mixing pan one superhigh speed, under action of centrifugal force, make seed outwards quicken to dish out along the radial passage of batch mixing pan, high speed impact is to the bump back-up ring, because the collision effect of impact, the shell of the seed shell benevolence of breaking is separated, thereby realize the shelling of seed, and the discharging opening below the effect of gravity falls to casing, enter down and separate manufacturing procedure together.

The utlity model has following good effect: 1, simple in structure, dependable performance; 2 because the batch mixing pan rotating speed is adjustable, and the adaptability of its processing is wider, can be suitable for processing the seed of various crop such as rape, especially the very big linseed of shelling difficulty is also had good shelling effect; 3, husking yield height, fines content is low, and crudy is good.

Fig. 1 is the structure chart of facing of an embodiment of the utility model.

Further describe embodiment of the present utility model below in conjunction with accompanying drawing, has frame 1, frame is made by the shaped steel welding, be installed into hopper 3 on the crossbeam 2 of frame top, the exit of feed hopper lower end is equipped with an adjustable pipe 4, adjustable pipe and the cover phase configuration that is fixed on the loam cake charging aperture, adjustable pipe can be moved up and down, back branch head screw 11 lockings put in place, by regulating the vertical range between outlet of adjustable pipe lower end and the batch mixing pan, regulate the size of batch mixing pan central space, thereby control and adjustment inlet amount, the feed hopper below is equipped with the casing 14 that connects firmly with frame, casing upper end configuration loam cake 5, the loam cake middle part is offered charging hole 13 and is connected mutually with adjustable pipe, one batch mixing pan 6 is installed above in casing, the card of batch mixing pan is provided with some radial passages, peripheral correspondence at batch mixing pan is equipped with the bump back-up ring 7 that connects firmly mutually with casing 14, bump back-up ring inwall is even surface and separates an intersegmental distance with batch mixing pan, batch mixing pan and vertical shaft assembly 9 link, the vertical shaft assembly comprises outer shaft sleeve that connects firmly with frame and the vertical shaft that is installed in the outer shaft sleeve, the lower end of vertical shaft links with speed-changing driving device 12 by a pair of belt pulley 10, speed-changing driving device is a variable speed electric motors, particularly by voltage changer control, can carry out stepless speed regulation to the rotating speed of batch mixing pan, to adapt to the shelling processing characteristics of different seeds, guarantee crudy, in addition, a side offers discharging opening 11 in the lower end of casing 14, the below of casing be gather materials bucket-shaped, so that gliding in the gravity effect, the seed after the shelling drops down onto discharging opening, to enter down separation circuit together.
