(54) MACHINE FOR CLEANING BAHCHEVB1H CULTURES

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to the mechanization of production processes in melon growing.

According to the main author. St. No. 753387 is a known machine for harvesting gourds, containing an elastic drum, forming a catch zone with lift elements, and a receiving conveyor, the lifting element being made in the form of parallelly installed, relative to the profile axis of the machine, the tongues whose nose pieces are equipped with fruit-shifting strings, and tail - to a guide, installed equidistantly to the surface of the drum and made with a rounding at the end. In addition, the lifting elements are made of at least four polozov, the middle of which have a greater length than the extreme at least the size of the maximum size of the fruit 1.

However, the implementation of the shanks of the skid elements by copying is associated with the need to install their ends with an excess over the receiving conveyor of no less than the range of copy heights. In connection with this, an increase in the damage of the fruits is created when they fall on the pressure conveyor and the height of the fruits increases in the process of their selection, i.e., the capture zone.

5 The purpose of the invention is to increase

reliability of fruit seizure and reduction of their damageability.

The goal is achieved by the fact that

for harvesting melons between runners, jj forging elements, rollers with

elastic rims located on

common shaft.

FIG. 1 shows the proposed device, side view; in fig. 2 - the same, top view.

The supporting device includes a frame 1 with fruit-sliding plates 2 mounted on it, an elastic drum 3, polozkovye elements 4, rollers 5 with a common shaft and a pressure conveyor 6.

The ends of the skid elements 4, the envelopes of the elastic drum, are tucked with rubber and are installed with an interval preventing jamming of the fruits between them as they rise. They end at the height that determines the installation level.

above the ground of the rotating shaft of the rollers 5. The rollers have an elastic rim with a diameter of about 200 mm and are located in the intervals between the skid elements. The top surface of the rollers 5 is matched without a difference with the working surface of the receiving conveyor 6 and in the embodiment of the embodiment of the conveyor, which is finger-operated and crimped, the last entrance into the interval between the rollers.

When the device moves across the field, the fruit-shifting flaps 2 roll the fruit into the capture zone between the elastic drum 3 and the skid elements 4. Going up along the skid elements, the fruits without a drop enter into interaction with the elastic rims of the rotating rollers 5, by means of which they rise to the receiving level conveyor 6.

The installation between the skidding elements of the rollers, eliminating differences in the rise of the fruit, eliminates the damage of the latter. This allows to significantly increase the translational speed of the maschina on the selection of fruits and increase its productivity with high quality work.
