DV-3 Rock Picker

Versatile and great value for money.

The DV-3 is a high performance machine.

It is a towed unit, attached to the tractor by means of a hitch specially designed to support the loads generated by the machine.

A machine designed to collect all types and sizes of stones.

It incorporates an independent hydraulic system powered by a PTO-driven hydraulic pump that powers all hydraulic motors. This allows the hydraulic system to be easily adjusted to the speed and pressure required to cope with the demands of the different conditions in which it is working.

The mouth of the machine has a blade with replaceable tips (PATENTED) and collectors. These collectors increase the sweep of the machine and increase the volume of material entering the elevator for screening.

The machine is equipped with a floating reel (PATENTED) which is composed of replaceable teeth. The reel consists of two pivoting arms that allow it to move up and down controlled by single-acting hydraulic damping cylinders. These cylinders can control the height of the reel. It is designed to advance larger stones and larger volumes of soil into the screen elevator to avoid blockages. It also breaks up clods and weeds to aid in their removal.

The two hydraulic cylinders on the drawbar are used to control the depth up to 50 cm and to lift the working machine for transport.

Once the material has passed through the mouth of the machine and has reached the elevator chain (PATENTED), it is screened, leaving the rock and stone in the elevator, to be deposited on the TANK, and the soil is filtered through the chains and returned to the ground.

This allows the machine to pick stones between 16 mm and 150 cm.

The screened stones are deposited on the 3.3 m3 TANK which can be discharged to the ground. This is achieved by hydraulically lifting the machine and tilting the TANK hydraulically.
