Description

A kind of corn screening machine

technical field

The utility model relates to a screening machine, in particular to a corn screening machine.

Background technique

In northern my country, corn is the main grain stored. After harvesting and threshing, corn will be mixed with some impurities, such as corn ears and dust. The quality of the crop, meanwhile, can also increase the workload for warehouse cleanup. The corn screening machine of existing design all is to adopt to place the screen at a certain angle, and drives the screen to vibrate through devices such as motors and springs, so as to realize the screening of corn particles. This kind of design will have certain deficiencies in the use process. First of all, through the vibration screening method, impurities such as corn ears and dust mixed in the corn will float into the air and form dust, which is not conducive to the working environment of workers. Affect the living environment of surrounding residents. Secondly, through vibration screening, if the vibration force is not enough, the satisfactory screening effect cannot be achieved. If the vibration force is too large, the corn particles will directly fall from the screen to the ground, and the collection work must be carried out after screening, which is a waste of time.

detailed description

In order to clearly illustrate the technical features of this solution, the utility model will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

As shown in Figures 1-2, the present embodiment discloses a corn screening machine, comprising a frame 1 and a cylindrical screening bin 2, and a feeding port 21 and a feeding port are arranged on the top of the cylindrical screening bin 2 Baffle plate 22; motor 3 and motor bracket 31 are provided at the bottom of the screening bin, metal filter screen 4 and transmission shaft 5 are arranged inside the screening bin 2, and the metal filter screen 4 is connected to the motor through the transmission shaft 5 3 are connected; the metal filter screen 4 is conical, and on the wall where the conical surface of the metal filter screen 4 contacts with the screening bin 2, a discharge port 41 and a discharge port baffle plate 42 are provided; The bottom of metal filter screen 4 is provided with collection chamber 6, collection chamber outlet 61, collection chamber outlet baffle plate 62 and collection chamber bottom plate 63, and described collection chamber bottom plate 63 is certain inclination angle with horizontal direction; The inner wall of the screening bin 2 is provided with triangular blades 7, the distance between the triangular blades 7 and the conical surface of the metal filter screen 4 is 0.5-1 cm, and the number of the triangular blades 7 is more than two; The feed inlet baffle 22 , the discharge outlet baffle 42 and the collection chamber outlet baffle 62 are connected with the screening bin 2 through a rotating shaft.

When starting corn screening, first open the feed inlet baffle 22, pour the corn into the screening bin 2 from the feed inlet 21, and then put the feed inlet baffle 22, the discharge outlet baffle 42 and the collection chamber outlet baffle 62 is closed, so that the impurity dust generated in the screening process can not float out from the screening chamber 2. Then open the motor 3, the motor 3 provides power for the metal filter screen 4 through the rotating shaft 5, and the metal filter screen 4 is rotated. At this time, the triangular blade 7 located on the inner wall of the screening bin plays the role of stirring the corn and impurities along with the rotation of the metal filter 4, so that the corn and impurities move from low to high along the surface of the metal filter 4 with a conical structure. Do circular motion from high to low. Because the vibration screening method is not adopted, and the screening bin is closed, the corn grains will not fall from the screening bin to the ground. Preferably, on the triangular blade 7, a number of round holes with a diameter larger than the corn grains can be provided. When the metal filter screen 4 rotates, the corn grains can pass through the round holes smoothly, preventing part of the corn grains from forming on one side of the triangular blade. Accumulation, unable to move together with the metal filter screen 4, can not complete the filtration; in addition, it can also reduce the force that the corn particles do relative movement on the triangular blade 7 for a long time to prevent the deformation of the blade.

Through the circular movement on the surface of the metal filter 4 and the agitation of the triangular blades 7, impurities such as ears of corn and dust fall through the mesh of the metal filter 4 to the collection chamber 6 at the bottom of the metal filter 4, because the aggregate The lower part of the chamber 6 is an inclined bottom plate 63, and the filtered impurities automatically slide down along the bottom plate 63 to the outlet 61 of the collection chamber, and only need to open the outlet baffle plate 62 of the collection chamber to collect and process the filtered impurities conveniently. Because the discharge opening 41 is positioned on the bin wall where the conical surface of the metal filter screen 4 contacts with the screening bin 2, after the screening is completed, the corn particles slide down to the discharge opening 41 along the conical surface of the metal filter screen 4, and the discharge opening is opened. plate 42, the corn grains that have been filtered can be taken out from the discharge port 41.

In summary, during the corn screening process, the utility model can reduce the dust generated by impurities on the outside of the screening machine, and the corn grains being screened will not fall from the equipment, avoiding the work of collecting scattered corn grains.

The parts of the utility model that are not described in detail are the known techniques of those skilled in the art. Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
