Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce the loss of cereal grass grain and energy consumption. The device for stripping-cutting grass grasses at the root consists of a drive combing drum 2 installed on the frame 1. On the drum 2, the comb strips are fixed on the drum 2. Each comb is made of TWO parts: movable 4 in transverse direction relative to the direction of movement of the device and stationary 5. The fixed part is made in the form of U-shaped teeth and is fixed on the shaft 6 of the drum 2 with the formation of a cavity. In the cavity there is a movable part 4 of the comb. The shaft 6 is installed inside the drum 2 by means of cranks eccentric to its axis, which makes it possible to eject the teeth of the combs. When the drum 2 is rotated, each comb at the time of insertion into the stem is pulled out of the drum 2 by the largest reach. In this case, the teeth of the movable part 4 of the comb are located in the cavity of the fixed part 5. As the drum 2 continues to rotate, the combs are pushed into the drum, and the movable part 4 moves out of the cavity of the fixed part 5. At the same time, the gap between the teeth decreases. Deformation and breakage of the stem occurs at two points with a bend in the vertical plane, which provides a more complete stripping of the inflorescences. 2 h. the item of f-ly, 4 silt and 4M 21 SAE Yu 00 y v v 22 (rig.

Description

This invention relates to; agricultural machinery, namely, devices for the weeding of plants at the root.

The purpose of the invention is to reduce the loss of cereal grass grain and energy consumption.

On fi1-. shows the proposed device, side view, section; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1 (at the introduction of the comb in the stem); in fig. 4 - the same, when stripping cliffs of grass inflorescences.

The device consists of a frame 1 on which a stripping working body is fixed, made up in the form of a driving drum 2 having longitudinal slits 3 along the side surface, in which combing teeth with teeth are placed with the possibility of changing the outreach. Each comb consists of two parts: a movable 4 and a fixed 5. The stationary part 5 of the comb is made in the form of U-shaped teeth, but inside and facing the inside of the drum 2 with free ends fixed to the protrusions of the shaft 6, which is eccentrically mounted by Krivostip 7 and 8 on the frame 1. With the help of the lever 9, the shaft is fixed relative to the frame 1 and the drum 2 in the corresponding position. The drum 2 with its end flanges 10 and 11 is mounted on cranks 7 and 8 with the possibility of rotation relative to the latter. In the cavity of the teeth of the fixed part 5 of the comb, a movable part 4 is installed, consisting of a base 12 and teeth 13. The base 12 is provided with longitudinal slots 14 and stops 15 with rollers 16 at the ends. The stops 15 are located in the openings of the flange 1 of the drum 2. The bases 12 of the movable parts 4 of the dies are spring-loaded in the longitudinal direction. In the slots 14, the sleeves 17 mounted on the bolts 18 fixedly mounted in the apertures 19 of the fixed part 5 of the combs are arranged for movement in them. The frame 1 has nanoravlushchie 20, in contact with the rollers of the stops 15. The drum 2 is covered at the top and bottom of the casing 2 and the supply) behind the conveyor 22 for removal of the resulting heap.

The device works as follows.

When the drum 2 rotates, each comb, moving in slots 3 of its side surface, at the moment of insertion into the stem, moves out of the drum 2 to the largest outreach of the teeth. P |) and this tooth 13 of the movable part 4 of the comb is located in the cavities of the teeth of the stationary part 5. As the drum 2 continues to rotate on cranks 7 and 8, the child starts to go into the drum 2, the movable part 4 of the stand moves out of the cavity of the stationary part 5, reducing the gap between their teeth due to the interaction of the rollers of the stops 15 with the guide 20 of the frame 1. At the same time, the movable part 4 of the comb with the slits 4 moves relative to the sleeves 17 on the bolts 18, and the stops 15 in the holes of the flanges P. According to as the gap between the teeth decreases combs deformation of the stems and seizure of social blossoms. The deformation of the stems occurs at two points and the breakage of the stem can be carried out at the same points. As the drum 2 rotates further, the gap between the teeth of the dies begins to grow and the extension of the product into the lateral surface that the inflorescence collides with the teeth. Next, the inflorescences of the plants with the casing 21 are collected on the conveyor 22, which leads them to the bunker of the vehicle. Pinching at two points of the stems with their

A curvature in a vertical plane in different directions allows a more complete brushing of the inflorescences of cereal grasses. A deformed stem requires significantly less force to break than

“Deformed, which, in turn, leads to a decrease in peak loads on the teeth of the comb, and consequently, to a reduction in the energy consumption for the implementation of the technological process.
