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 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 trauma of potato tubers from impact with previous spoons and the walls of the planting apparatus when dropped.

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 (Postnikov N.M., Belyaev A.E., Kan M.I. Potato-planting machines. M .. Engineering, 1981, 43-44).

The disadvantage of these elevator machines is that after the spoons exit the vertical position, the potato tubers in free flight fall into the capture zone between the elevator and the inclined bottom of the nutrient hopper, a gap forms in which the tubers rush, which leads to losses, damage, and uneven operation of the planting apparatus .

Closest to the proposed device is a potato planting unit (RU 2208924, 7 А01С 9/02, 2003.07.27) containing a frame, sowing apparatus, furrow-open coulter, support element and shorting. The potato planter planting apparatus contains an elevator with spoons rigidly attached thereto to capture tubers. In the lower part of the elevator, a feed hopper is installed, formed by the side walls and the lower bottom. For the passage of the spoons, the lower bottom is installed with a window in relation to the elevator. The feed hopper adjoins the common potato planter hopper in the upper part is equipped with an adjustable shutter, and the lower bottom is mounted on different-sized elastic joints and receives oscillatory movements from the eccentric shaft. On the outside, the elevator with spoons is surrounded by walls forming a tuber pipe.

The disadvantage of this unit is the uneven operation of the planting apparatus. Potato tubers in the fall are injured from collisions with the previous spoons and pinching between the spoons and the walls of the tuber.

The purpose of this utility model is to increase the uniformity of the layout of tubers, eliminating the collision and pinching of potato tubers with previous spoons and walls of the tuber.

This goal is achieved by the proposed device for planting potatoes, which, like the prototype, contains a frame, a device for planting potatoes, a furrow-open coulter, a support element and shorters, an elevator with spoons attached to it to capture potato tubers. The elevator is mounted on drums mounted on the drive shaft. In the lower part of the elevator, as well as in the prototype, a feed hopper is installed. The feed hopper is adjacent to the common potato planter bunker, in the upper part it is equipped with an adjustable shutter. On the outside, the elevator with spoons is surrounded by walls forming a tuber pipe. The device for planting potatoes is an elevator of the conveyor type to the surface of which, with the help of bolts, in parallel in two rows are attached spoons connected by a hinge.

Neighboring spoons in relation to each other can be located on the same level or in a checkerboard pattern. The distance between the spoons is adjusted by moving them relative to the elevator belt on which they are fixed, in addition, other sizes of spoons can be installed on the elevator, which makes it possible to configure the device for planting potato tubers of large, medium and small size.

Unlike the prototype, according to the utility model, spoons mounted on a belt conveyor type elevator are mounted with the possibility of changing position depending on location and pivotally interconnected. When moving "bottom-up" take a horizontal position, move the tubers along the tubers to the upper position. After the passage of the upper position, the potato tubers are separated from the spoons, which in turn are folded and, when moving “from top to bottom,” take a vertical position, thereby freeing up the tuber conduit cavity and allowing the tubers to move freely in the free flow into the potato planting zone.

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 working bodies in such a technological sequence that eliminates obstacles to falling potato tubers by forming a free channel inside the tubers 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 reason to consider it relevant to the eligibility criterion of "novelty."

The essence of the claimed utility model is illustrated by drawings, in which 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 (KSM-6), side view; figure 2 is a device for planting potatoes, side view; Fig.3 spoons.

A device for planting potatoes 3 is mounted on the frame 1 of the potato planting machine, for example KSM-4 (KSM-6) (figure 1). and contains an elevator 9 with spoons 7 mounted on it to capture potato tubers. The elevator 9 is mounted on drums 8 mounted on the drive shaft 2. In the lower part of the elevator, as in the prototype, a feed hopper 11 is installed, which adjoins the common potato planter hopper 1 and is equipped with an adjustable shutter 10. From the outside, the elevator with spoons is surrounded by walls 12 forming a tuber pipe 13. To the surface of the elevator 9 with the help of bolts 17 in parallel in two rows are attached the base 16 of the spoons 7, interconnected by a hinge 18 (Fig. 3, a, b). Spoons 7, mounted on the elevator conveyor belt type 9, are made folding when moving "from top to down" in the cavity of the tuber conduit (Fig.2, Fig.3. C).

Neighboring spoons 7, in relation to each other can be located on the same level or in a checkerboard pattern. The distance between the spoons 7 is adjusted by moving them relative to the elevator belt 9 on which they are fixed, in addition, other sizes 7 spoons can be installed on the elevator 9, which makes it possible to configure the device for planting potato tubers of large, medium and small size.

The unit operates as follows. When the unit is moving, the device for potato planting is driven from the tractor’s power take-off shaft through gearbox 4 or from the supporting-drive wheels, gear block 5 and chain gear 6. The furrow cutter 14 forms a furrow, the potato planting device lowers the tubers at the same distance to the bottom of the furrow, and disks of hills 15 dig a furrow with tubers. Under the action of the vibration of the aggregate, the potato tubers from the hopper 1 fall into the feed hopper 11. When the potato planter moves, the elevator 9 is activated, which picks up the tubers with its spoons 7 in the cavity of the feed hopper 11 and from bottom to top (Fig. 2, Fig. 2. 3. b) the spoons 7 take a horizontal position, move the tubers along the tuber duct 13 to the upper position. After the passage of the upper position, the potato tubers are separated from the spoons 7, which, in turn, are folded under the weight of their mass and, when moving “from top to bottom” (Fig. 2, Fig. 3. C), take a vertical position, thereby freeing the cavity of the tuber duct 13 and ensuring the free movement of tubers in free flight into the potato planting zone.

The distance between the spoons is adjusted by moving them relative to the conveyor belt on which they are fixed, in addition, spoons of other sizes can be installed, which makes it possible to set up a planting apparatus for planting large, medium and small potato tubers.

The proposed design of a device for planting potatoes is important for potato farms and private producers from the point of view of ensuring uniform distribution of potato tubers and reducing the damage to potato tubers.

The positive effect of the use of a device for planting potatoes is to reduce trauma, the uniformity of the layout of tubers when planting potatoes.
