Abstract

FIELD: forestry.

SUBSTANCE: invention can be used to create sub-canopy crops in local areas and promote reforestation. The dispenser for individual sowing of seeds contains a body with a bottom part and a lid, handles, and a seed tube. The dispenser is equipped with a die with a petal cradle for receiving seeds, a petal magazine for moving seeds into the seed tube and sowing line, and a pusher with a brush-bristle coating, connected by an elastic connection to a movable handle. The movable handle is mounted on a hinge in the lid and combined with the fixed handle by a spring, while the movable handle provides drive for the translational movement of the pusher and individual loading of seeds into the die.

Description

The invention relates to the field of forestry and can be used to create sub-canopy crops in local areas and promote reforestation.

A seed dispenser with a flexible sowing disc is known (patent No. RU 2494596 C2 published on October 10, 2013). A seed meter for use in an agricultural seeding machine, comprising: a housing having an internal chamber and a deflector within the internal chamber, and a sowing disk with a rigid hub, rotatably installed in the housing, made fully or partially flexible in at least one radial section , which is deflected by at least one deflector when rotating inside the housing.

The disadvantage of the analogue is the complexity of the design and kinematics of movement of the working parts.

A manual seeder is known - a cane (patent No. RU 2154367 C2 published on August 20, 2000), including a hollow tubular rod for seeds with a sowing apparatus and a pusher, a spring-loaded seed tube telescopically connected to the hollow rod with a device for forming a seed bed and a support ring, characterized in that in the seed tube there are spiral grooves with straight sections, and in the tubular rod - transverse grooves, while the tubular rod is equipped with a rotary dispenser with a finger, which is located between the upper and lower plugs, the latter also has a finger, and the finger connected to the dispenser interacts with the transverse and spiral grooves, and the finger connected to the lower plug has spiral grooves; in addition, the seed tube has the ability to rotate on the support ring, and rippers are mounted on its guide sleeve.

This technical solution is closest to the declared one and is accepted as a prototype. The disadvantage of the prototype is the complexity and low-tech design, damage to the seeds.

The purpose of the present invention is to simplify the design and increase the reliability of individual seed dosing. This is achieved by the fact that the dispenser for individual sowing of seeds, containing a body with a bottom part and a cover, handles, a seed tube, is equipped with a die with a petal holder for receiving seeds, a petal magazine for moving seeds into the seed tube and sowing line, a pusher with a brush-bristle coating, connected by an elastic connection to a handle pivotally mounted in the lid, combined with a fixed handle by a spring, while the movable handle provides a drive for the translational movement of the pusher and individual loading of seeds into the die.

The invention is illustrated by drawings, where figure 1 shows a general sectional view of the dispenser, figure 2 shows a cross-section of the die, figure 3 shows a pusher, top view.

The dispenser for individual sowing of seeds includes a body 1, a spring 2, handles 3, 4, a hinge 5, a cover 6, a hatch 7, an elastic connection 8, a pusher 9, a brush-bristle coating 10, a petal cradle 11, a die body 12, a seed tube 13, seed material 14, clamp 15, petal magazine 16, platform 17.

The dispenser works as follows. Seed material 14 is loaded into the housing 1 through a hatch 7 onto the bottom, while the pusher 9 with a brush-bristle coating 10 is in its original position and is in contact over the entire surface through the bristles with the bottom surface. Through an elastic connection 8, the pusher is connected to the working arm of the articulated handle 4, which is also in its original position. Handle 3 is fixedly fixed on the lid and combined by spring 2 with handle 4, which allows you to manually change the distance between the handles. When the handle 4 is rotated from the manual drive in the hinge 5 at a certain angle through the working arm of the link and the elastic connection 8, the pusher 9 moves horizontally along the bottom part. An elastic connection ensures constant contact of the brush-bristle coating with the surface of the bottom part. On the bottom part, flush with the surface, a die with a petal holder 11 is installed and secured with a clamp 15, allowing it to accept one seed. In this case, in the initial position, the die is located in front of the edge of the pusher with a brush-bristle coating and is free to receive one seed, an array of which covers the area around the die.

In the upper part of the die body 12 there is a petal cradle 11, into which one seed is placed, part of the shell of which is flush or protrudes above the level of the bottom surface. The seed is held in the lodgement by elastically movable petals.

When the pusher is moved by a manual drive from the articulated handle 4 through the elastic connection 8, the elastic elements of the brush-bristle coating shift the layer of seed material along the surface of the bottom part, act selectively with the elastic elements of the brush coating on the seed located in the cradle and push it from the cradle into the petal magazine 16 , freeing up the space of the petal cradle and creating a place for the subsequent entry of the seed. Thus, the coated pusher displaces the layer of seed material 14 and, when moving back to its original position, provides access for loading the next seed into the cradle. The elastic elements of the brush-bristle coating provide a gentle effect on the seed material loaded into the die. From the petal tray, the seeds are fed into the petal magazine 16, which consists of a number of sequentially located petal cells, which individually hold the seed material in the petal magazine throughout the entire working area. After filling the petal magazine with seeds, with each subsequent arrival of seeds from the petal cradle, the batch of seeds located in the petal magazine is promoted, and at the exit, the seeds arrive individually into the seed tube 13 and then into the sowing line.

The dispenser can be installed on a boom or sowing unit (not shown) through platform 17.

Thus, the claimed technical solution makes it possible to simplify the design of the device, avoid damage to seeds, and increase the reliability of individual seed sowing.
