Description

The utility model relates to the field of primary processing of bast plants, namely, devices for the mechanical processing of stalks of bast crops and the production of a bonfiber mixture / fiber, and can be used to obtain a fibrous semi-finished product from stalks of straw or trusts directly at the site of growing plants, mainly linen.

A device for processing bast stems in the field [Pat. Utility Model 161243. Russian Federation. Device for processing bast stems in the field / Vnukov V.G., Kupriyanov B.C., Fedosova N.M .; Applicant and patent holder LLC AGROLEN-INVEST. - Publ. 04/10/2016]. The device consists of a base, a disintegrator, an air duct, a fan, a slotted funnel, a pick-up device, and a cutting unit. The disadvantages of the device include the impossibility of differentiating the process of bast raw materials processing, as well as the high likelihood of land and stones getting into the disintegrator, which can lead to damage to the headset and its failure. The specified device is essentially the closest to the claimed, therefore, adopted as a prototype.

The technical task of the utility model is to develop a device for processing bast stems, mainly linen, in the field.

The technical result of the utility model is the ability to control the processing of raw materials by selecting a rational rotational speed of the disintegrator rotor and fan impeller depending on the properties of the stems, as well as increasing the reliability of the device by creating conditions for the earth and stones to leave the stalk layer before they enter the processing zone.

The order and relative position of the elements of the claimed device is shown in FIG. 1-2.

In FIG. 1 shows the location of the elements of the device in side view.

In FIG. 2 shows the arrangement of elements of the device in a plan view.

The claimed utility model consists of the following elements and assemblies: 1 - pick-up device, 2 - slotted funnel, 3 - fan, 4 - air duct, 5 - disintegrator, 6 - base.

The utility model operates as follows. Material (whole stalks of straw or trusts lying in the ribbon or chaotically) with the headset of a pick-up device 1 operating from a hydraulic actuator rises from the linen and moves up to the slotted funnel 2, in the working area of which they fall into the air flow created by fan 3. The fan is installed asymmetrically across the width of the picking device and across the width of the incoming stem layer. This ensures that the stalks turn along the air flow when they fall into the fan coverage area (into the slotted funnel). In addition, in this design, the fan is placed at an angle to the base 6 so that the suction hole is located above the material. In this case, the earth and stones do not fall into the processing zone along with the stems. Then the stems through the duct 4 enter the working area of the disintegrator 5, where there is a destruction of their structure and the formation of a bonfiber mixture. The air flow formed by the rotary rotor of the disintegrator moves the bonfiber mixture obtained by the interaction of the material with the working bodies of the disintegrator to the outlet of the disintegrator, and then to the drive, which can be used as a tractor trolley, hopper, etc. All elements and components of the device are mounted on the base 6, equipped with wheels, which is easily mounted on the tractor.

The disintegrator and fan are driven by belt / gears from the power take-off shaft connected to the tractor engine, using replaceable pulleys / gears, which differ in design parameters that provide the necessary fan air speed. This is due to the following aspect. In order to ensure the economic efficiency of the claimed device, in addition to its productivity in passing raw materials, an important characteristic is the quality of the obtained fibrous product. Quality, in turn, is ensured by a rational combination of the loading density of the stem mass and the speed mode of the rotor of the disintegrator, which ensures the maximum possible degree of separation of wood from the fiber contained in the stems. When determining the loading density of the stem mass, the geometric and mass characteristics of the processed stems (length and diameter of the stem, mass of the stem / 1000 stems, etc.) must be taken into account. Before the device starts to work on the stalk growth area, their qualitative characteristics (organoleptic or instrumental) are evaluated and according to the dependencies that describe the influence of the disintegrator loading density on the quality of the obtained fibrous product and obtained empirically, the required fan speed of the power supply fan is selected and a pulley is installed on the fan shaft / sprocket of the required size. The aforementioned will allow us to differentiate the processing process and, thereby, ensure efficient processing of bast materials.
