Abstract

A rotary feeding machine with leaned blades comprises a shell, a transmission device, a rotary shaft and multiple leaned blades. The transmission device is arranged on the lateral surface of the shell. The rotary shaft is arranged inside the shell with two ends traversing out from the shell. One end of the rotary shaft outside the shell is connected with the transmission device. The utility model is characterized in that: the leaned blades and the rotary shaft are arranged inclined and the leaned blades are fixed on the rotary shaft; the leaned blades are combined with the shell to form multiple closed cavities.

Description

Leaned blade formula rotary feeder

(1) technical field

The utility model relates to a kind of rotary feeder, especially relates to leaned blade formula rotary feeder.

(2) background technology

Leaned blade formula rotary feeder is a kind of of rotary feeder, its effect be utilize cavity that the blade be evenly distributed on the shaft circumference and housing form by rotation with granular material continuous be expelled to discharging opening from inlet point, the material of discharging opening relies on its deadweight discharge.At present, common rotary feeder is evenly distributed on blade and the shaft parallel on the shaft circumference, must form the gap with housing because relatively rotate when rotated, the discharging opening of upper end and the discharging opening of lower end are divided into two ends with the gap of blade rotary area, wherein in blade when rotation, contact with the material in the inlet point of upper end is first, carry the material rotation then and form an osed top cavity with housing, material drains into discharging opening by deadweight when continuing rotating blade to discharge gate, finish one-time feeding, continue the rotation circulation and discharge material realization continuous-feeding.Its problem is because blade in the above-mentioned rotating shaft and rotating shaft relatively rotate the gap that forms with housing, will inevitably form the material of clearance margin with housing when blade rotates to the gap after the inlet point material feeding rub, shear effect, because be evenly distributed on blade and shaft parallel on the shaft circumference, just can proceed work after when running into the jam material, needing big shearing force with the material chopping, so shearing force jam when not enough appears in blade easily, the abominable consequences such as damage that cause deformation failure or other parts of blade, and the wearing and tearing of blade are also very big.The method of head it off all concentrates on the material of blade now, change in the measures such as shape of inlet point, though these methods can improve the effect of rotary feeder to a certain extent, but can't change the influence that the jam of material brings, also can't change the problem of serious wear simultaneously.

(3) summary of the invention

In order to solve the technical matters that above-mentioned prior art exists, the utility model provides a kind of leaned blade formula rotary feeder, and this device has not only solved the problem of material jam, has also improved the performance of blade wear.

The technical scheme that adopts is:

Leaned blade formula rotary feeder, comprise housing, driving device, rotating shaft, a plurality of leaned blade, it is characterized in that described driving device is arranged on the outside of housing and is fixed on the housing, rotating shaft is arranged in the housing, its two ends pass outside the housing, one side traversing through end is connected with driving device, and a plurality of leaned blades and axes of rotation skew setting also are fixed in the rotating shaft, and a plurality of leaned blades cooperate a plurality of enclosed cavities of formation with housing.

Principle of work: material enters enclosure interior by the upper end inlet point of housing, with the leaned blade direct contact in the rotating shaft, be filled in the enclosed cavity of leaned blade and housing formation, rotation along with rotating shaft, synchronously an end of the leaned blade of rotation can with housing to material formation gradually shear, rather than whole blade and housing form the shearing to material, when the material jam, tilting blade utilizes the thrust of leaning angle to make the material slippage in the space of next door material, owing to be longer than the inlet point of housing on the leaned blade structure, two ends and housing at leaned blade form cavity respectively, rather than positive powerful extruding is moved the jam material, be rotated further rotating shaft, when material rotates to the discharging opening place of housing in enclosed cavity, draw off by deadweight.

The utility model has solved the jam problem of blade and material, the utility model utilizes the leaned blade that is provided with the axes of rotation skew angle, avoid the direct shear between blade and the material, not only can improve the life-span of blade, also guaranteed material complete in the feed process.

Fig. 2 is the birds-eye view of Fig. 1.

Fig. 3 is a block diagram of the present utility model.

(5) specific embodiment

Please refer to figure one, leaned blade formula rotary feeder of the present utility model, comprise housing 1, rotating shaft 2, a plurality of leaned blades 3, driving device 4, the centre slice of housing 1 is provided with a rotating shaft 2, stretch out outside the housing 1 at the two ends of rotating shaft, and supported by the bearing that is installed in housing 1 both sides, one end of rotating shaft 2 is connected with driving device 4, a plurality of leaned blades 3 are obliquely installed and are fixed in the rotating shaft 2 with rotating shaft 2, a plurality of leaned blades 3 can rotate with rotating shaft 2, and cooperate with the middle circle shell of column of housing 1 and to form enclosed cavity, inlet point and housing 1 that housing 1 is all stretched out at a plurality of leaned blades 3 two ends form cavity, and driving device 4 is arranged on the outside of housing 1 and is fixed on the housing 1.Material enters housing 1 inside by the upper end inlet point of housing 1, with a plurality of leaned blades 3 direct contacts in the rotating shaft 2, be filled in the enclosed cavity of a plurality of leaned blades 3 and housing 1 formation, rotation along with rotating shaft 2, an end of a plurality of leaned blades 3 of rotation can be sheared with the formation gradually of 1 pair of material of housing synchronously, when the material thrust that a plurality of leaned blades 3 utilize leaning angle during by jam with the material slippage in the space of next door material, owing to be longer than the inlet point of housing 1 on a plurality of leaned blade 3 structures, two ends and housing 1 at a plurality of leaned blades 3 form cavity respectively, when two ends are arrived in the slippage of jam material, self-adapting type enters in the cavity, be rotated further rotating shaft, draw off by deadweight when material rotates to the discharging opening of housing 1 with enclosed cavity.Its characteristics one be a plurality of leaned blades 3 in rotary course, run into the material that is subjected to jam after, utilize tilting push away the angle with the material slippage in the space of next door material, utilize the jam of the material that the material self adaptation avoids, make discharge smooth and easy; Its characteristics two are to be longer than the inlet point of housing 1 on a plurality of leaned blade 3 structures, two ends and housing 1 at a plurality of leaned blades 3 form cavity respectively, only a few jam material is when aside the material space can't hold, and a plurality of leaned blades 3 can be passed standby cavity with the jam material.
