Description

The invention relates to agricultural machinery, in particular, machines for picking fruits, roots and potatoes from the soil surface.

The purpose of the invention is to improve the quality of work and reduce losses.

FIG. 1 is a schematic side view of the needle pick-up: FIG. 2 — node I in FIG. one; in fig. 3 is a view A of FIG. one; in fig. 4 shows a section BB in FIG. one.

The needle pick-up contains small 1 and large 2 drums, which are covered by an infinite belt 3. The axis of the small drum 1 is located above the axis of the large drum 2, and the lower branch of the endless belt 3 is pressed from below by the pressure device 4. Before the drum 2, two spring-loaded rollers 5 are mounted. drum 1 is mounted on a pivot arm 6, hinged

on the axis of the bass drum 2 and spring-loaded relative to the frame of the machine; the agitator is made in the form of a unbalance mechanism 7 and is placed on the axis of the snare drum 1 in its front parts. The endless belt 3 is made of an IC of a rubberized conveyor belt 8 and on its edges the driving chains 9 are fixed.

The needles 10 are located in the holes of the tape 8, are rigidly connected to its inner side by three plates 11 and are located at the vertices of an equilateral triangle, and the triangular plates 11 are arranged in rows of alternating bases and vertices of adjacent triangles. The plates 11 are provided with arcuate brackets 12, through which the elastic threads 13 are passed. The needles 10 are inclined at an angle p in the direction of the movement of the belt 3.

Under the snare drum 1 is mounted transporting-charge device 14.

Needle pickup works as follows.

The large drum 2, resting on the soil surface, under the action of its own mass, presses the needles 10 into the soil, piercing the tubers 15 or lump of soil 16. The connection of the needles with 10 triangular plates 11 ensures the stability of the puncturing process in both the longitudinal and transverse directions.

When moving forward (in arrow B), drum 2 rotates by moving tape 3 through gland 4 to snare 1. Needles 10 remove tubers 15 and part of soil lumps 16 from the surface layer of previously loosened soil. drum 1 relative to the axis of the big drum 2. Since the oscillation amplitude increases as it approaches the snare drum 1, first the clods of soil 16 are separated from the needles 10, and then as the vibrations of the tubers 15 increase. the vibrations are adjusted so that the separation of the tubers 15 takes place over the transporting and unloading device 14. At the same time, the lateral load on the needles is eliminated and damage to the fruits is reduced when they are removed from the needles.

Due to the fact that the needles 10 are inclined forward, prickling occurs almost vertically at the initial moment, which contributes to a stronger adhesion of the tubers 15 to the needles 10. When the needles 10 leave the soil, the presence of an inclination angle (3 allows the same surface adhesion coefficient needles 10 with tubers 15 provide a large amount of vertical force that removes the ball from the soil.

When the belt 3 moves to the idle branch, the needles 10 are held by elastic threads 13, passing through the arms 12 and fixed on the belt 3, which also increases the reliability of the pick-up operation.
