Description

The invention relates to agricultural production and is intended for removing corn cobs by peeling and ejecting with simultaneous calibration and separate packing of small and large grain fractions, as well as crushed cobs.

The main requirements include operation in enclosed spaces and indoor areas with the initial supply of whole ears of corn through the receiving hopper with an upper rubber flap into the working chamber with a threshing drum, which is placed in rolling bearings strictly along the vertical axis of symmetry, at the lower end of which the drive axis is fixed along the axis of symmetry of the drum a pulley with a belt drive from an electric motor.

The closest analogue, taken as a prototype, is known as “Electric coats of corn ears” “Eluk” manufactured by PJSC “Electric motor, consisting of an electric motor, a working chamber, a working body (disk), a working chamber lid, an ejection gate valve and a grain ejection tray. Designed for use in personal subsidiary plots and therefore adopted as a prototype.

The most significant drawback of the prototype is the lack of receiving containers in its design for both small and large fractions of refined grains, as well as separately fractions of crushed corn cobs, that is, the actual line of commodity processing, sorting of the final product and its waste for packing.

Unlike the prototype, the lower part of the design of the proposed device for cleaning corn ears from grain is equipped with a vertically adjustable and pivotally suspended to the chamber (bunker) receiving grate with bottom holes for passing small and large fractions of peeled grains, as well as fractions of crushed corn ears (Fig. 1, Fig. 2), including the following components: a trapezoidal groove 1, equipped with ears 2 fixed to its vertical faces by means of two Roman nuts (talpers) 3 and pivotally to the ears 4 with spikes 5 n a horizontal horizontal cleaner of cobs from the grains of the working chamber of the hopper 6 with the upper cover 7 and with a bearing 8 located on the vertical axis of symmetry, the cover 7 being made with an inclined receiving nozzle 9, which is equipped with an elastic rubber receiving flap 10 fixed from the inside and from the top to fill the whole corn cobs coming from above into the chamber to the threshing drum 11, where they are cleaned simultaneously with their spikes, followed by the ejection of the peeled whole ears into the open cover 12, and also burn the spikes of the rotor blade 13 located symmetrically on the longitudinal axis of the mounting of the lower bearing 14, at the end of the shaft of which the belt drive pulley 15 is installed, the whole device is equipped with a support frame 16, and the cleaned corn grains are sorted into fine fractions of the cleaned grains 17 and large, respectively fractions of peeled grains 18, while the crushed fractions of corn cobs 19 are packaged by ejecting them with the downwardly inclined end of the trough 1 into the located extreme container. At the same time, the corn cobs 20 (Fig. 2), previously cleaned from wrappers and grains, are thrown out through the open cover 12 (Fig. 1), which is specially located in the working chamber of the hopper 6 and is specially located in the opposite lower case.

Thus, unlike the prototype, the improvement of the design of the proposed device for cleaning corn ears will allow to realize a significant advantage, eliminating the necessary need for additional manual labor for sorting, calibration and packing of grain of crushed small and large fractions of ears of corn.

The aim of the invention is to expand the operational performance of the device and increase the intensity and completeness of cleaning corn cobs from grains.

To achieve this goal (Fig. 1, Fig. 2), the chute 1 is fixed to the tray 24 of the chamber 6 of the device for cleaning corn ears from grain, has a trapezoidal shape and is pivotally connected to the chamber of the hopper 6 through a pair of ears 2 and 4, as well as with an intermediate a pair of Roman nuts 3, allowing you to adjust the slope of the rolling angle of peeled small grains 17, large grains 18 and peeled minced cobs 19 down its mesh bottom with calibration holes of grids 22 for small and 23 for large fractions of refined grain, as well as for packing them in a container STI 17 and 18, and crushed cobs in a container 19.

At the same time, the tray 24 for ejecting grain, which receives them during feeding into the receiving nozzle 9 with a rubber flap 10 of unpeeled corn cobs, and ejecting the cobs cleaned from grains through the cover 12 of the hopper 6 with the top cover 7, is connected to the vertical axis of the threshing drum 11 by means of bearings rolling elements 8 and 14, on the lower end of which the belt pulley 15 is fitted to the rotation shaft of the electric motor 26.

In FIG. 1 shows a design diagram of a device for cleaning corn cobs from grain, side view;

in FIG. 2 - the same, top view.

The design for cleaning corn cobs from grain includes a chute 1 with ears 2, a Roman nut 3 with ears 4, spikes 5, a hopper 6 (chamber) with a top cover 7 and rolling bearings 8 and 14, a pulley 15 with a belt pulley is placed on the lower end of the last one the transmission, which is located on the supporting frame 16, the sealing containers 17, 18 and 19 (Fig. 1), respectively, cleaned small 22 and large 23 fractions of grain and whole cobs 20 cleaned from grain (Fig. 2), the drive working disk 21, the receiving grid for the passage of small grains 22 and large grains 23, a tray 24 for passing peeled grains and chopped cobs (Fig. 2).

The technological process of the operation of the device, designed to work both indoors and in special indoor areas with a canopy, having an electric drive with a voltage of 220 V, is not carried out immediately after harvesting, but preferably after a period of time corresponding to the initial exit of grains in the cobs from the state of milk wax ripeness, that is, in order to exclude losses from possible damage.

Claims (1)
