Abstract
The utility model relates to a shaftless transmission type cylindrical precleaner which comprises a machine frame wall board, a speed reducer, a motor, a screening drum, a discharging bucket and a fan. The speed reducer is fixedly arranged on the machine frame wall board through the motor, a flange shaft is arranged at one end of the speed reducer, the flange shaft is connected to the screening drum, the motor is connected with the speed reducer, the speed reducer is driven by the motor, continuous spiral guide plates are arranged on the inner wall of the screening drum, the discharging bucket is arranged on the machine frame wall board and under the screening drum, and the fan is arranged in the screening drum and connected to the flange shaft. The shaftless transmission type cylindrical precleaner is simple in structure, free of complex transmission chains, high in transmission efficiency, low in cost and high in reliability. Meanwhile, the fan can blow sundries of light weight and large size out of the screening drum to further improve the cleaning effect.
Description
Technical field
The utility model relates to a kind of receiving sieve, is specifically related to a kind of shaftless driven type cylindrical pre-cleaning screen, belongs to Cereals Processing Machines technical field.
Background technology
The cylindrical pre-cleaning screen of prior art adopts motor, reductor, chain that power is passed to main shaft conventionally, drives screen drum to rotate by main shaft.This kind of drive complex structure, cost is high, transmission chain length, reliability is low.
Meanwhile, existing cylindrical pre-cleaning screen can not be to lightweight, and bulky impurity (as straw) is effectively removed, thus impact screening quality.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel shaftless driven type cylindrical pre-cleaning screen, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, transmission efficiency is high, the measured shaftless driven type cylindrical pre-cleaning screen of screening matter.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of shaftless driven type cylindrical pre-cleaning screen, and it comprises frame plate, reductor, motor, screen drum, discharge bucket and fan; Wherein, described reductor is immobilizated on frame plate by a motor rack, and its one end is provided with a flange shaft; Described flange shaft is connected on screen drum; Described motor connects and drives reductor; The inwall of described screen drum is provided with continuous spiral guide plate; Described discharge bucket is installed on frame plate, and it is positioned at the below of screen drum; Described fan is contained in screen drum, and it is also connected in flange shaft.
Shaftless driven type cylindrical pre-cleaning screen of the present utility model is further set to: in one end of described screen drum, one end cap is installed, the central authorities of this end cap offer a slag notch, and this slag notch and fan are oppositely arranged.
Shaftless driven type cylindrical pre-cleaning screen of the present utility model is also set to: be provided with garbage-cleaning plate in the bottom of described screen drum.
Compared with prior art, the utlity model has following beneficial effect: shaftless driven type cylindrical pre-cleaning screen of the present utility model is simple in structure, there is no complicated driving-chain, and transmission efficiency is high, has reduced cost, and reliability is high; Meanwhile, it can blow out screen drum by lightweight, bulky impurity, further to have improved cleaning effect by fan is set.
Brief description of the drawings
Fig. 1 is the structural representation of shaftless driven type cylindrical pre-cleaning screen of the present utility model.
Detailed description of the invention
Refer to shown in Figure of description 1, the utility model is a kind of shaftless driven type cylindrical pre-cleaning screen, and it is made up of several parts such as frame plate 1, reductor 2, motor 3, screen drum 4, discharge bucket 5 and fans 6.
Wherein, described reductor 2 is immobilizated on frame plate 1 by a motor rack 7.Described motor rack 7 is welded on frame plate 1, its cross section structure triangular in shape.
One end of described reductor 2 is provided with a flange shaft 8, and described flange shaft 8 is connected on screen drum 4, thereby screen drum 4 is rotated and screen cereal, this kind of drive dispenses the intermediate link of transmission, make simple in structure, cost, reliability increases, and transmission efficiency is high.
Described motor 3 connects and drives reductor 2.
The inwall of described screen drum 4 is provided with continuous spiral guide plate 9, thereby can stir cereal, avoids cereal to stop up the sieve aperture of screen drum 4.One end cap 10 is installed in one end of described screen drum 4, and the central authorities of this end cap 10 offer a slag notch 11.Be provided with garbage-cleaning plate 12 in the bottom of described screen drum 4, open garbage-cleaning plate 12, can remove the impurity in screen drum 4.
Described discharge bucket 5 is installed on frame plate 1, and it is positioned at the below of screen drum 4, and it is for the cereal after splendid attire screening.
Described fan 6 is contained in screen drum 4, and it is also connected in flange shaft 7.By this fan 6 is set, can be by lightweight, bulky impurity blows out screen drum 4, further to have improved cleaning effect.
Above detailed description of the invention is only the preferred embodiment of this creation, not in order to limit this creation, any amendment of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
