Abstract

The invention relates to methods for extracting peat from an undisturbed structure. The purpose of the invention is to reduce the complexity of the process and intensify the drying. On a preliminary drained peat deposit, closed drainage slots are laid in staggered order on both sides of the map. The peat mining machine, moving along the map, produces cutting of continuous peat bands. Simultaneously with the cutting of the tape, it is rotated to the side face. A gap (B – H) is formed between adjacent tapes, where B and H are the width and height of the tape being cut, respectively, and the H / B ratio is 0.5–06. With this ratio, an increased collection of peat per hectare and a sufficiently high resistance coefficient are provided. After pre-drying, continuous peat ribbons laid out on the side to 55% moisture are formed into figures for further drying. The formation of drying patterns is carried out by two-sided transverse shearing (forging) of continuous peat bands with simultaneous rotation relative to the longitudinal axis.

Description

The invention relates to methods for extracting peat from an undisturbed structure.

The purpose of the invention is to reduce the complexity of the process and intensify the drying.

FIG. 1 shows the general, and the scheme of implementation of the method of extraction of peat undisturbed structure; in fig. 2 - the same plan view; in fig. 3 - turning the ribbons to the side face in the process of cutting them; in fig. 4 is a view A of FIG. 3; on

ki, significantly lengthen its terms, or requires repeated rolls of tapes.

When the ratio of cross-sectional sizes of the peat ribbon is 6, the drying conditions B are worsened as a result of an increase in the thickness of the ribbon and a decrease in the gaps between adjacent ribbons. At the same time, tapes with a cross section did not have time to dry out over the season to a standard humidity of 50%, being in the figures of sushifig. 5 - formation of a drying shape of a button, and a tape with a cross section, of transverse shear mites; in fig. 6 - 450x280, 450x300, 500x280, 500300, 500К320-section BB in FIG. five; in fig. 7 is the cross section of the humidity of 55%, even when it was found in b-B in FIG. five.

On pre-drained system

style.

After pre-drying laid out 25

gross 1 and cardboard 2 channels of peat - 4 with continuous to the lateral edge of the continuous ribbon deposits lay closed forest dof to a humidity of 55% they are formed by sandwiches, spruce 3, placed them in chess - in figure 6 for the next, to her drying.

The formation of drying patterns is carried out by two-sided transverse shear (roll) of continuous peat tapes with their simultaneous twist relative to the longitudinal axis. In the figures, peat is dried to a standard moisture content of 50%, after which it is cleaned either into transport trailers with transportation to the warehouse or directly to the consumer, or to a stack of long-term storage 7 located on the middle of the card, followed by isolation with a plastic film.

Cutting out continuous ribbons of the undisturbed peat structure from the deposit, simultaneously turning them to the side face and subsequent formation of patterns into the figures, as compared to the prototype, will greatly simplify the technology of peat extraction of undisturbed structures for cutting or drying the strips or tours, eliminating the need for peat of various cross sections of complex and inefficient machines on

drying formation operations.

The handling of continuous ribbons instead of cut peat bricks makes it possible to use simpler, more reliable, and high average sushi- ing time — 40 coproducting equipment and gear from 42 to 60 days; increased peatly reduce the labor intensity of peat extraction

The order is on both sides of the card 4. The closed drainage slots are laid with a slope from the center of the card and communicate with the card channels.

A peat mining machine equipped with vertical and horizontal cutting devices (not shown), moving along the map, cuts continuous peat tapes 5. Simultaneously with the cutting, the continuous tape is rotated to the side face, and a gap (B – H) is formed between adjacent tapes where B and H, are the width and height of the tape, respectively.

In order to establish the optimum dimensions on the cross section of the tape, and consequently, the gap between them, both from the point of view of the drying conditions, the stability of the tapes turned on the side, as well as the amounts of charges, experimental

As a result of experimental work, it was found that peat ribbons with a ratio of cross-sectional sizes of 5-0.6 have several advantages.

peat from 1 ha (up to 456 tons with the cross-sectional dimensions of the tape 430 "270 mm) and a rather high resistance coefficient.

When the ratio of the size of the transverse. ribbon section, 5, despite the favorable drying conditions (relatively small thickness of the tape, the presence of large gaps between adjacent tapes in the spread), their resistance coefficient on the drying field is very low (Og 0.13 to 0.35). CQ

undisturbed structure in general.

Laying closed drainage slots will allow better drying of the surface of the stacking of continuous peat bands and ensure reliable rainwater removal, which will improve the conditions for drying peat and eliminate the need for additional costs, provided that drying continues during the following season.

Claims (1)

Invention Formula As a result, JEeHTbi with a total length of 435 to 325 m occurs on the length of the card at 500 m (Lo6n). The tape has a wide edge on the peat underlay. The formula of the invention The method of peat extraction, which includes cutting rectangular ribbons from a deposit, separating their deposits leads to the disturbance of gaps 55 from the deposit and spread them on the drying field between adjacent tents and constant swathing and cleaning into folding units, saturating them with moisture from the contact wetted by the fact that, with the aim of reducing bedding, which violates the process of drying the complexity of the method and intensification ki, significantly lengthen its terms, or requires repeated rolls of tapes. When the ratio of cross-sectional sizes of the peat ribbon, 6 conditions of drying B are worsened as a result of an increase in the thickness of the ribbon and a decrease in the gaps between adjacent ribbons. At the same time, tapes with a cross section did not have time to dry up to a standard moisture content of 50% for the season, were in the drying figures, and tapes with a cross section, 450x280, 450x300, 500x280, 500300, 500К320- to a moisture content of 55%, even if they were in a drift. After pre-drying laid out on the damaged structure as a whole. Laying closed drainage slots will allow better drying of the surface of the stacking of continuous peat bands and ensure reliable rainwater removal, which will improve the conditions for drying peat and eliminate the need for additional costs, provided that drying continues during the following season. Invention Formula drying, simultaneously with the cutting of the tape, it is rotated to the lateral face with the formation of a gap between the tapes equal to B – H, where I and B are, respectively, the height and width of the tape, while fig 7 0.6, and raking is performed by two-way transverse shear of continuous ribbons laid on the side face with simultaneous rotation relative to the longitudinal axis.
