RU2527286C1 - Device for single fracture of oilseeds - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: device of single fracture comprises an electric motor with variable rotor speed, a drive-multiplier comprising a horizontal shaft and a vertical shaft mating by the screw drive. The working part comprises a deck-bumper, a receiving pipe, a discharge tube. Inside the deck-bumper a starting disc is coaxially located. In the process of sloughing the material through the receiving pipe, entering the starting disc is accelerated by the centrifugal forces in the radial tubes, faced with reflective ribs of the deck-bumper mounted at an angle of 45° to the generator of the housing, crushed and discharged from the workspace by the air flow through the discharge tube. The upper plate and the shell with holes protect the particles from the repeated strike, and the impact of the edges of the holes is prevented by air flow passing along the radial tubes and reinforced by the radial plates of elastic material.

EFFECT: invention enables to improve the quality of the obtained particles.

Description

The present invention relates to the oil industry and can be used for the collapse of seeds of flax, rapeseed, camelina and other conditionally oil-free oil crops.

A device for hulling sunflower seeds [1]. The feeder of the device is made in the form of cones and a mechanism for regulating the point of entry of seeds on the blades of the disk, the deck is made of shock-absorbing material, an additional screen housing is mounted on ball bearings with a device for separating husks from seed kernels. The mechanism for controlling the point of contact with the rotor blades adjusts the necessary impact force of the scouring blades on the seeds.

The disadvantage of this design is that a certain amount of seeds collides with the ribs of the rotor blades and bounces towards the lower surfaces of the feeder, as a result of which a multiple blow occurs, which affects the quality of the resulting rush.

Closest to the invention is a device for crushing seeds [2]. When the hub of the device rotates in radial channels, a vacuum is created. As a result of the rotation of the rotor, a centrifugal force arises, which orientes the seeds with a large geometric axis as they move from the loading center to the periphery to the deck. As a result of the movement of seeds in radial channels, they additionally come into contact with the guides, which contributes to a clearer orientation of the initial product with its large geometric axis. At the exit from the radial channels, the product to be collapsed acquires the maximum linear velocity, and upon impact on the deck, the surface shell is destroyed. The disadvantage is that as a result of the rebound of the particles towards the rotor, the particles again re-fracture against the side surface of the rotor.

The basis of the invention is the task of providing a single free kick in the working space of the machine.

The problem is solved in that the device for a single destruction contains a drive-multiplier with an adjustable speed, a cylindrical body and an axisymmetric receiving pipe, a deck with reflective ribs installed at an angle of 45 ° to the generatrix of the body, a tangential discharge pipe, and the accelerating disk may contain radial tubes rigidly installed between two plates, the lateral surface of the accelerating disk can be provided with a shell with holes matching the ends of the radial cutting, and the lower surface of the disc can be fixed radial plate of elastic material.

Figure 1 shows a diagram of a device for a single destruction.

The device for a single destruction contains an electric motor 1 with an adjustable rotor speed, a drive-multiplier 2, including a horizontal shaft 3 and a vertical shaft 4, conjugated by a helical gear 5. The working part 6 includes a deck chipper 7, a receiving pipe 8, an unloading pipe 9. Inside the deck -the bump is coaxially located accelerating disk 10.

Figure 2 presents the accelerating disk containing a Central landing sleeve 11, radial tubes 12, rigidly fixed between the upper plate 13 and the base of the disk 14. A shell with holes 15 is fixed on the side surface, and radial plates of elastic material 16 are mounted on the lower surface.

The electric motor 1 through the horizontal shaft 3 and the helical gear 5 drives the accelerating disk 10, rigidly mounted on the vertical shaft 4. The destructible material through the receiving pipe 8 enters the accelerating disk on its base 14, accelerates by centrifugal forces in the radial tubes 12, collides with reflective the ribs of the baffle plate 7, installed at an angle of 45 ° to the generatrix of the body, are destroyed and discharged from the working space through the discharge pipe 9 by air flow a knitting plate 13 and a shell with holes 15, and a collision with the edges of the holes is prevented by the air flow going through the radial tubes 12 and reinforced by radial plates of elastic material 16.

Thus, the proposed device allows for the destruction of a single free blow without overgrinding the material.
