Description

The inventive utility model relates to agriculture, in particular to the planting apparatus of potato planters. A predominantly useful model can be used when planting potato tubers of various fractions (large, medium, small).

Known elevator machines used in the potato planters SKK-1 for planting whole, sprouted potatoes, and KP-2 for planting vernalized potatoes. The SKK-1 landing gear is equipped with a hook chain, to the links of which metal spoons are attached [1. Postnikov N.M., Belyaev A.E., Kan M.I. Potato planting machines. M .. Engineering, 1981, 43-44.].

The disadvantage of these elevator devices is that after the spoon with the tuber leaves the capture zone between the elevator and the inclined bottom of the feed hopper, a gap forms in which the tubers rush, which leads to losses, damage, and uneven operation of the planting apparatus. In the transition from planting large potato tubers to medium or small tubers, it is necessary to replace all spoons of elevator apparatus, which determines the high complexity of the operation.

Known combined potato planting unit (RU 2020786, class A01C 9/04, 1994), containing a frame, a metering device with a chain drive, a furrow-open coulter, a support element and shorting.

The disadvantage of this unit is the uneven operation of the planting apparatus, the inability to plant potato tubers of various fractions.

Closest to the proposed device is a potato planting unit for mini-agricultural machinery, containing a loading hopper with a tedder connected to the planting apparatus through the vas deferens, closing discs and a furrow mounted on the transport wheels with the possibility of mutual movement.

The landing gear consists of a spring cutter and a drum. The drum is made in the form of conical surfaces connected above the furrow, cells are made at the junction, at the bottom of which elastic pillows are installed. The drum is rigidly connected by an axis with quick-detachable transport wheels.

The disadvantage of this unit is the uneven operation of the planting apparatus, low productivity, the inability to plant potato tubers of various fractions.

The purpose of this utility model is to increase the uniformity of the layout of potato tubers when planting potatoes of large, medium or small fractions.

This goal is achieved by the proposed device for planting potatoes, which, as in the prototype, is a drum mounted on a shaft that is attached to the frame of a potato planting machine. The drum consists of two disk-type disks movable relative to the shaft, opposed to each other with the possibility of adjusting the distance between them. Plates are attached to the inner surface of the disks at an angle to each other, copying the relief of the disk and forming cells between the plates. The angle between the plates is 30-60 °. Setting the angle between the plates less than 30 ° makes it difficult for potato tubers to get into the cells during rotation of the discs and, on the contrary, setting the angle between the plates more than 60 ° makes it possible for two or more tubers to get into the cells, which is not allowed by agrotechnical requirements.

The distance between the discs is regulated by moving the disk-type discs relative to the shaft on which they are mounted, which makes it possible to set up devices for planting large, medium and small potato tubers in a short time.

A comparative analysis with known technical solutions and a prototype shows that the inventive device for planting potatoes is characterized by the presence of new structural elements and the placement of the working bodies in such a technological sequence that provides the ability to quickly configure the device for planting potatoes of large, medium and small size with high quality, reliability and with the least energy consumption.

The analysis of patent and scientific and technical literature did not reveal technical solutions identical to the claimed device for planting potatoes, which gives grounds to consider them to meet the eligibility criterion of "novelty."

The essence of the claimed utility model is illustrated by drawings, where Fig. 1 shows a diagram of the proposed device for planting potatoes mounted on the frame of a potato planting machine, for example KSM-4 (6), side view; figure 2 - a device for planting potatoes; figure 3 - disk disk type, side view.

A device for planting potatoes is a drum 3 mounted on a shaft 2, which is mounted on the frame of a potato planting machine, for example KSM-4 (KSM-6) (figure 1). The drum consists of two disk-type disks 7 movable relative to the shaft 2 (FIG. 2), oppositely arranged relative to each other with the possibility of adjusting the distance between them, plates 8 are copied to the inner surface of the disks 7 at an angle to each other, copying the relief of the disk 7 and forming cells between the plates. The angle between the plates 8 is 30-60 ° (figure 3). The distance between the disks is regulated by moving the disks 7 and installing the clips 9 in the grooves 10 on the shaft 2. The disks 7 (Fig. 2) placed on the shaft 2 are fixed from turning by means of keys 11.

The unit operates as follows. When the unit is moving, the drive of the device for planting potatoes is carried out from the tractor power take-off shaft or from the supporting-drive wheels through the gearbox 4 and gear block 5. The furrow cutter 12 forms a furrow, the device for planting potatoes lowers the tubers at the same distance to the bottom of the furrow, and the okuchniki disks 13 dig a furrow with tubers. Under the action of the vibration of the aggregate, the potato tubers from the hopper 1 get to the drum 3. When the disks 7 of the drum 3 rotate, the potato tubers fall into the cells bounded by the plates 8 and, when further rotated, under the influence of their own weight, fall into the furrow cutter 12, and then they are sealed by the discs with furrows 13. The diameter of the planted potato tubers is regulated by changing the distance between the disks 7. The distance between the disks 7 is regulated by moving them relative to the shaft 2, on which they are fixed, which allows us Royko in a short time, the device for planting potato tubers large, medium and small size

The proposed design of a device for planting potatoes is important for potato farms and private producers from the point of view of determining the possibility of planting potato tubers, with different weight characteristics.

The positive effect of the use of a device for planting potatoes is to increase productivity, uniform layout of tubers when planting potatoes of large, medium or small fractions.
