Abstract

The machine for planting seedlings with a closed root system includes a frame, a cabin, a coulter, a chute, a seat and compacting rollers. The interchangeable chute installed in the coulter cavity is pivotally connected to it and spring-loaded relative to the chute. The cross section of the gutter corresponds to the shape of the soil briquette of the seedling and slightly exceeds its size. The lower part of the gutter is made in the form of a concave curved surface with an increasing radius of curvature. The rear part of the gutter coincides with the edges of the sides of the coulter equipped with rod extensions, the length of each subsequent lower rod being shorter than the upper previous one. at the clearings.

Description

The utility model relates to forestry, in particular to forest planting machines for planting seedlings with a closed root system when creating forest crops on clearings.

Planting material with a closed root system is increasingly used in the forest complex due to its high survival rate and growth in forest crops [1]. However, the lack of reliable and productive means of mechanization for planting hinders the widespread use of seedlings with a closed root system in the creation of forest crops on clearings.

A known machine for planting seedlings with a closed root system (US Pat. No. 2546163, A01C, 11/02, publ. 04/10/2015, bull. 10), including a frame, wheels, rollers, coulter, vertical seeder, made in the form of a square tube and equipped with a spring-loaded shutter, a feed conveyor and a flat belt landing apparatus.

The main disadvantages of this machine are the incomplete coordination and synchronization of the feed mechanism and the flat-belt double-handed landing gear due to slipping belts and, as a result, poor landing quality, as well as low reliability of the executive mechanisms of the machine.

Known planting apparatus for a forest planting machine (AS No. 435781, A01C 11/02, publ. 15.07.74, bull. 26), adopted by the applicant for the prototype, including a vertical gutter located in the coulter, equipped with a shutter blocking it from the bottom and attached to the lever mechanism and the trough in the upper and lower parts is equipped with two pairs of spring strips installed on top of each other, the ends of which are in contact.

A significant drawback of such a planting apparatus is its complex and cumbersome design due to the presence of a lever mechanism with a cam drive and unsatisfactory planting quality due to the inability to provide the required planting depth and embedment of the plant root system, enclosed in soil briquettes of various shapes and sizes.

The utility model is based on the task of improving the quality of planting seedlings with a closed root system, simplifying the design of the machine and improving its performance and, as a result, performance indicators when working on clearings.

This goal is achieved by the fact that the interchangeable groove installed in the cavity of the coulter is pivotally connected to the coulter and spring-loaded to it. The cross section of the gutter is similar to the shape of the soil briquette of the seedling and slightly exceeds its size, and the lower part of the gutter is made in the form of a concave curvilinear surface with an increasing radius of curvature, and the back of the gutter coincides with the edges of the openers provided with rod extensions.

An analysis of the prior art by the applicant, including a search by patent and scientific and technical sources of information and identified sources of information containing information about analogues of the claimed solution, made it possible to establish that no analogues were found that are characterized by features identical to the new essential features of the claimed utility model.

The analysis made it possible to identify a set of essential distinguishing features in comparison with the known achieved result.

The specified set of features set forth in the formula of the utility model.

Therefore, the claimed utility model meets the requirement of "novelty."

Also, according to the search results, it was found that the claimed technical solution is not obvious to specialists based on the prior art, therefore, it meets the requirement of "inventive step" and is industrially applicable.

Figure 1 shows the proposed machine, figure 2 is a section aa. The machine contains a frame 1, a cab 2, a coulter 3, a spring 4, a groove 5, rod extensions 7, a seat 8 and compacting rollers 9.

The opener 3 is a hollow box construction, with a groove 5 located in it, which is pivotally connected to the opener and spring-loaded to it with an adjustable force. Seat 8 is located in the cab on the side (left or right) of the opener. In cross section, the shape of the gutter 10 corresponds to the shape of the soil briquette of the seedling and slightly exceeds its size. The lower part of the gutter 5 is made in the form of a concave curved surface with an increasing radius of curvature and the rear part of the gutter coincides with the edges of the opener sides equipped with rod extensions 7, the length of each subsequent lower rod being shorter than the upper previous one.

The machine operates as follows. A tractor in an aggregate with a machine for planting seedlings with a closed root system calls into the landing strip and the operator puts it into working position. With the translational movement of the unit, the opener 3 penetrates into the soil and forms a landing gap in it. The planter, taking seedling 6 by the crown, lowers it into the groove 5, until the soil briquette touches it, while the spring 4 is stretched under the influence of the mass of the briquette, the groove drops down to contact the bottom of the landing slit. The briquette moves along the chute to the end of the coulter, and the planter accompanies it until the briquettes begin to fill the soil with rollers 9. Rod extensions 7 help to keep the briquette in an upright position, and thanks to the shortened lower rods, the briquetting of the soil begins immediately after it leaves the coulter. The final compaction of the soil briquette of the seedling is carried out by rollers 9.

The implementation of the machine for planting seedlings with a closed root system with the proposed device will provide the required planting depth, improve planting quality, simplify the design of the machine and improve its performance when working on clearings.
