DE2912891A1 - MACHINE FOR HARVESTING BEET FRUIT AND ROOT VEGETABLES BY THE ROUGH ROAD PROCESS - Google Patents

Description

Title of the invention:

"Machine for harvesting beet crops and root vegetables using the rough digging method"

Field of application of the invention:

The invention relates to a machine for harvesting beet crops and root vegetables, both on light and on heavy soils are used to achieve a clean crop can be.

Characteristic of the known technical solutions: Raifrode machines for root vegetables are known which have a single row work and two-row self-propelled machines. The separated beets are loaded immediately after the separation via the conveyor line sieve chain - loading elevator. The testing of a machine designed in this way showed that there was a high proportion of herb and earth admixtures in the crop on wet and heavy soils, which interfered with the subsequent processing and did not allow the beets to be stored.

Aim of the invention:

The aim of the invention is to increase the work performance compared to the known machines and to achieve the greatest possible separation of residual weeds, fine herbs and soil additions in the machine and thus a clean, storable crop

to reach.

Explain the essence of the invention:

The invention is based on the object of providing a machine for harvesting beet crops and root vegetables using the harvesting method to create, which can be arranged as a semi-trailer on traction means.

With the potato harvesting machines type E 665 - E 684 and the already In the case of heavy and wet soils, the sieve section is not sufficient to remove the soil and weeds to reduce in the harvest according to the required harvest quality. The invention made a machine created, which almost eliminates the mentioned deficiency.

According to the invention the object is achieved in that the machine from a combination of improved elements, such as intake, lifting share, haulm cross conveyor belt and haulm discharge chute:. · ι: with pick-up and separation devices common in agricultural machinery, such as haulm separating devices for root crop harvesting machines (WP 129 727), elevator for root crop harvesting machines (WP 108 636) and drive device for sieve belts on potato harvesting machines (WP 109 977) is formed. The machine consists of a frame with running gear in which the working and j? örder elements are arranged. There are two in front of the frame Shares arranged symmetrically, designed as hook shares and characterized by an additional articulated joint are. The drawbars are guided past the receptacle on the left and right, while the leg is designed so that the coulter plate is arranged in the detection area under the receptacle. By adjusting the drawbars of the share it is possible to adapt the assignment of the visual plate in the detection area to the requirements.

The recording is made of a frame that is inclined in the chassis and is pivotable with a pair of ruffing belts and formed the receiving spar with articulated drive, swivel and deflection disks and has torpedoes at the front, wherein an impeller is arranged under the central torpedo, on which the recording is supported during work. Are in the frame two pairs of known separating devices articulated in such a way that the working strands of the rowing belt pairs in the inlet gap the separating device. The respective outer separating roller the separating device is resiliently supported by two straight guides on the frame, while the inner separating rollers are rigidly hinged. The rowing belts, which are arranged in pairs, are moved beyond the cutting device to across the machine arranged haulm conveyor continued.

There is a fine haulm discharge chute next to the outer separating rollers, in which the herb parts cut up by the separating device fall, while the one in the pair of working trunks stuck haulm is dropped onto the haulm conveyor. Below the separating device is a known sieve chain in Arranged in the longitudinal direction of the machine. The discharge roller is arranged in such a way that that the conveyed beet crops fall on a known inclined finger separating belt, the beet crops fall down onto the loading elevator, while the remaining pebbles and soil through the separating finger belt transported upwards and separated. The device is driven by the PTO shaft of the tractor, with the belt speed via a variator drive is adapted to the respective driving speed.

Embodiment:

The invention is to be explained using an exemplary embodiment. In the accompanying drawings show:

¥ ± β can be seen from Fig. 2, the hook coulter 3 consists of two parts, the detachably connected drawbar 19 and the leg 20 with base plate 21 «The drawbar 19 and leg 20 are pivotably connected by means of a joint 22 and are in the working position via the pawl 23 locked "The ropes 2k are attached to the pawl 23 and leg 20" When the coulter is lifted, first the pawl 23 is released from the locking device 25, then the entire hook coulter 3 is raised to the stop and then bent around the joint 22 "

As can be seen from FIG. 3, the separating device 4 consists of two pairs of separating rollers 26, the inner separating rollers 27 being rigid and the outer separating rollers 28 being fastened to the frame 1 via two spring straight guides 29 each. Laterally below the outer separating rollers 28 there are two discharge chutes 6 and above the rear part of the separating device k there is a haulm discharge belt 7 # arranged in the transverse direction.
