Description

The utility model relates to agricultural engineering, in particular to machines for harvesting feed from plant material.

A known press for pressing hay and straw without the use of binding material (see A.S. No. 130280, A01F 15/04 of 11/06/1959 - analogue), comprising a pick-up, a receiving chamber with packers, a pressing chamber with a piston reciprocating movements on which the rods for longitudinal bale firmware and the linkage mechanism equipped with rods stitching the bale from the sides are mounted.

The disadvantage of this device is the insufficient strength of the binder.

A device for legless pressing of plant material (see RF patent No. 2265312, A01F 15/04 of 04/20/2004 - prototype), including a pick-up, a receiving chamber with packers, a storage chamber with a packer, a pressing chamber with a press piston, a chamber for controlling the density of pressing, relaxation chamber and drive sprockets of the packers, and the packer of the storage chamber is installed with the possibility of coordinated work with the movement of the piston of the press and with a phase shift and at a speed two times less than the packers receiving th camera.

The disadvantage of this baler is the insufficient strength of the binder.

The technical result of the proposed utility model is to increase the strength of bale pressing without using strapping material.

The technical result is achieved by the fact that in the device for pressing plant material, including a pick-up, a receiving chamber with packers, a pressing chamber with a piston reciprocating, on which rods for longitudinal bale stitching are mounted, a chamber for controlling the pressing density and a relaxation chamber, according to utility model, the pressing chamber is made in the form of a rotating cylinder, and the pressing density control chamber is in the form of a rotating truncated cone, and to The cameras are mounted coaxially and with the possibility of synchronous rotation in one direction.

The novelty of the claimed technical result is due to the fact that due to the implementation of the pressing chamber and the compression density control chamber in the form of hollow bodies of revolution, which are mounted coaxially and synchronously rotate in one direction around the axis, the pressed material is compacted and bonded in two planes during its movement . The first plane coincides with the plane of movement of the piston, i.e. the axial direction of the bale, and the second plane coincides with the plane forming the compaction chamber and the compaction chamber density control, i.e. external contour of a bale. Such a complex translational-rotational movement increases the pressing density and the bonding area between the stems of the pressed material, which ensures the achievement of the technical result.

The essence of the utility model is illustrated by drawings, where figure 1 shows a General view of a device for pressing plant material; in figure 2 is a section aa of the pressing chamber and the compression density control chamber.

The device for pressing plant material consists of a pick-up 1, which is connected to a receiving chamber 2, in which the packers are located 3. Behind the receiving chamber 2 there is a pressing chamber 4, inside which the piston 5 reciprocates.

The rods 6 are arranged on the piston 5 for longitudinal firmware of the bale. The pressing chamber 4, made in the form of a rotating cylinder, is connected to the density control chamber 7, which is made in the form of a rotating truncated cone. In this case, the pressing chamber 4 and the pressing density control chamber 7 are mounted coaxially and make synchronous rotational movement in one direction. Behind the control chamber, pressing density 7, a relaxation chamber 8 is installed. The working bodies are driven by the drive system 9.

The operation of the device for pressing plant material is as follows.

Before the working stroke of the device for pressing plant material, technological and technical adjustments are made. In the process of movement, the pick-up 1 raises the stems of the pressed material and feeds them into the receiving chamber 2. From the receiving chamber 2, the plant material is fed by the packers 3 to the pressing chamber 4, which is made in the form of a rotating cylinder. In the pressing chamber 4, the piston 5, which performs reciprocating movements, pushes the plant material in the direction of its movement and compresses it during the forward movement. While the rods 6 capture part of the stems and stitch the pressed material in the axial direction relative to the movement of the piston. After the pressing chamber 4, the pressed material is fed into the density control chamber 7, in which the required pressing density is provided. In the process of pressing the material in the pressing chamber 4 and the chamber for controlling the density of pressing 7, due to their coaxial installation and synchronous rotation in one direction, the pressed material, in addition to its axial movement in the direction of movement of the piston, is carried into a rotational movement, thereby bonding it simultaneously two planes. After the chamber for controlling the density of pressing 7, the pressed material is fed into the relaxation chamber 8, where it is held and normal stresses undergo a slight plastic deformation of the pressed material. Thus, the proposed device for pressing plant material ensures the achievement of a technical result.
