Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The manual mower for single-row plots comprises a cutting machine 3 with a drive, bearing rollers 2, a wheel carriage 5, and a handle-leash 4 with the control units. The axis of the wheel carriage 5 is located behind the centre of gravity of the mower. The radius of the carriage 5 wheels is at least not less than the average height of the cutting of the mowed plants. Clearance of the carriage 5 is not less than the maximum height of the cutting. The cutting machine 3 has a divider-stalk ejector 6 with a stalk-collector.

EFFECT: manual mower for single-row plots provides increased labour efficiency.

Description

The invention relates to agricultural machinery, in particular to means of mechanization for harvesting single-row plots of plants of agricultural crops in breeding works.

Known means of mechanized harvesting single-row selective crops with manual pedestrian control, including a threshing device with a drive, support wheels, cutting apparatus and controls. For example, a single-row breeding grain harvesting machine developed by the GNU VNII of rice (“Machines for breeding, variety testing and primary seed growing of field crops.” Catalog. Moscow, 2009, pp. 47-48).

The advantage of using a single-row selection grain harvesting machine is the possibility of mechanized harvesting of one row of a plot.

The disadvantages of this machine:

- the machine does not fit into the accepted planting and harvesting patterns (OST 4672-78; OST 4673-78) and the technology established in the practice of breeding work (row spacing, the ability to harvest the entire plant without threshing);

- large clearance and diameter of the wheels, a small track (about 40 cm) determine the high location of the center of gravity of the machine and its instability;

- the uniaxial arrangement of the machine with a high center of gravity makes the machine difficult to control when moving in a row.

The closest in technical essence to the claimed device is a hand-held mower selected as a prototype, containing a cutting apparatus with a drive, track rollers and a leash handle with controls (GARDENA Battery lawn scissors complete with a handle (8830), http: // www. gardena.com/en/lawn-care/grass-shears/gardena-305365/).

A disadvantage of the known device is the unsatisfactory movement along the harvested row of selection crops, in addition, cut plants fall apart in different directions.

An object of the invention is to increase labor productivity when harvesting breeding single-row plots, providing selective harvesting, followed by the formation of a bunch of cut plants from single-row plots of agricultural crops.

The technical task is achieved in that the mower manual for single row plots containing a cutting apparatus with a drive, track rollers and a handle-leash with controls, according to the invention, is equipped with a wheel carriage, the axis of which is located beyond the center of gravity of the mower, the radius of its wheels, at least at least not less than the average cut height of the mowing plants, the clearance is not less than the maximum cut height, and the cutting apparatus is equipped with a divider-stalk tap with a stalk collector.

The invention is illustrated in the drawing.

Figure 1 shows a manual mower for single row plots, general view.

The mower includes a housing 1, track rollers 2, a cutting device 3 and a handle-leash 4 with controls, a wheel carriage 5, a divider-stalk tap 6 and a shutter-trap 7. The wheel carriage 5 is located behind the center of gravity of the device and is rigidly connected to the body of the mower 1 , while the radius of the wheel of the carriage 5 should be at least not less than the average cut height of the mowing plants, and the clearance of the carriage 5 - not less than the maximum cut height. Thus, the wheel carriage 5 provides a stable movement of the mower along the harvested row of selection crops. The divider-stalk tap 6, made in the form of a spatially-rod structure, is rigidly fixed to the wheel carriage 5 and helps to keep cut plants from falling apart. The shutter-trap 7 is located inside the divider-stalk tap 6 in front of the cutting apparatus 3, prevents deviation of the cut plants back and is made in the form of vertical interchangeable combs with elastic teeth located towards each other with overlap.

Manual mower works as follows.

The operator places the mower on the inter-tier path of breeding crops and brings it with a 6-stalk divider to the row (plot) to be cut and prepared in advance by the operator’s assistant, who forms the row (raises plants that are leaning on the next row, removes large weeds and lumps). After that, at the signal of the assistant, the operator turns on the cutting apparatus 3 and starts moving in a row. Cut stems of plants, passing through the channel of the divider-stalk tap 6 and held by its frame from decay during the movement of the mower, accumulate in the channel and form into a bunch. The trap-shutter 7 prevents the cut plants backward. Upon completion of cutting the entire row, the formed bunch of plants is picked up by the assistant operator, bandaged with twine, attached a label and placed on a harvested field. The operator transfers the mower to the next prepared plot and the process is repeated.

The effectiveness of the application of this invention (according to testing prototypes) is to increase labor productivity during harvesting by 15-20%.
