RU73152U1 - POTATO HARVESTING MACHINE - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular, to the working bodies of diggers and combines that separate soil impurities from root crops. The potato harvesting machine includes digging plowshares 1, a bar elevator 2, a cultivator-separation separator 3 with elliptical working blades 4, a reducer 6 driven by a tractor power take-off shaft, a chain drive of a bar elevator shaft 7, a drive elevator shaft 8, a ramp 9 and a running grill 9 and running wheels. A separation intensifier 3, a drive shaft, on which there are elliptical disks, which are equipped with elastic rubber cultivators along the outer perimeter 5, which loosen the soil and reduce tuber damage, are mounted above the elevator belt. The presence of rubber cultivators along the outer perimeter of the discs reduces the damage to tubers and reduces crop losses during potato harvesting.

Description

The utility model relates to agricultural engineering, in particular, to the working bodies of diggers and combines that separate soil impurities from root crops.

A device is known that contains digging plowshares, a sequentially placed bar elevator, over the conveyor belt of which a ripper-intensifier of separation is mounted with guide flanges and elliptical working bodies in the form of disks [1].

The disadvantage of this device is that a ripper-separation intensifier with metal guides and elliptical disks is mounted above the conveyor belt. This device has two disks and four working bodies in the form of elliptical disks. Such a number of disks located on one shaft leads to the collection of a dug layer in front of the working body. This leads to reduced productivity, unit shutdown, damage to tubers and increased yield losses.

The problem the utility model is aimed at eliminating the loading of a dug layer along the elevator width and reducing the damage to tubers.

The technical result of its use is to increase the separating capacity of the elevator due to the redistribution of the tuberous layer in the middle and to the edges of the elevator, which ensures uniform mass distribution along the width of the elevator, and elastic rubber cultivators on elliptical disks additionally loosen the soil and reduce damage to tubers.

The technical result is achieved by the fact that in a potato harvester containing digging shares, sequentially located

bar separating elevator, intensifier-cultivator with elliptical working bodies made in the form of disks, which are equipped with elastic cultivators fixed along the outer perimeter. It is advisable to use elastic rippers in the form of a truncated cone.

Figure 1 shows a machine for harvesting potatoes. Figure 2 is the same plan view. Figure 3 - ripper intensifier.

The machine for harvesting potato tubers includes digging plowshares 1, a bar elevator 2, a drive shaft 8, a chain gear 7, a gearbox 6, a pitched grill 9 and running wheels 10 [see figure 1].

Above the elevator canvas mounted ripper-intensifier separation 3 with elliptical working bodies 4 [see figure 1 and figure 2].

Figure 3: ripper-intensifier in the form of disks, at the ends of which elastic rubber rippers 5.

Potato harvester operates as follows.

During operation, the shares 1 dig the beds and transfer the tuberous layer to the bar elevator 2. The layer passes through the zone of action of the cultivator-intensifier 3, which provides improved soil separation due to the action of centrifugal forces on the tuberous layer by working bodies 4 with elastic rubber cultivators 5. Simultaneously, leveling the soil across the width of the elevator 2 and loosening it.

This embodiment of the machine for harvesting potatoes provides intensive separation of the soil, and the presence of rubber cultivators along the outer perimeter of the discs reduces the damage to tubers and reduces crop losses.
