UA81183C2 - Cleaner of root heads not yet cut down from top remains - Google Patents

Abstract

A cleaner of root heads not yet cut down from top remains has a console bearing element arranged in the longitudinal-vertical plane as an inclined one at the end of which a cleaning unit is mounted. It consists of two brushes arranged in the longitudinal-vertical plane at angle to each other with flat elastic disks fixed in perpendicular to axes thereof. The upper ends of the brushes are connected by means of gear wheels to a gearhead transmitting rotational motion in opposite directions.

Description

Description of the invention

The invention belongs to agricultural engineering, in particular to devices for cleaning the heads of 2 root crops from the remains of the root on the root, which are used in the harvesting machines.

A variety of root cleaners are known: impact (a.s. of the USSR Mo215641, AO1023/021, combing (a.s. of the USSR Mo163349, AO1023/021, combined (a.s. of the USSR Mo332802, AO1023/021), but from the point in view of minimal injury and loss of root crops during their cleaning, it is the combing cleaning working organs that are promising. Among them, disc cleaners stand out for their simplicity and efficiency, which comb the remains of 70 sticks from the heads of root crops with the help of an elastic disk installed on the drive horizontal shaft (a. pp. USSR Mo571213, AO1023/02, bulletin Mo33, 1977 I. Moving along the row of root crops, the disks deform, touching the head of the root crop and thanks to their elasticity and corrugated surface, they effectively separate the remains of the root crop from the root crops.

The well-known |"Cleaner of the heads of root crops from the remains of ghee" (Patent of Ukraine Мо30529 А, АО1023/02, 2000, 72 bulletin Mob II - prototype)), which has a block of cleaning elements installed on a cantilever drive shaft inclined in the longitudinal-vertical plane, at the end of which, in the form of a truncated cone, the top of which is directed downwards, thin elastic cleaning discs of different diameters are collected with gaps, and the base of the cone in the lower zone is horizontal, and there are a number of holes along the periphery of the discs. Moving gradually along the row of root crops and at the same time rotating, the inclined cantilever shaft with elastic disks moves along the heads of root crops, on which the dry and green remains of the ghee remained. At the same time, with this movement of the cleaning elements, each head of the root crop is between the elastic cleaning discs, which cover it from both sides tangentially and effectively comb the remains of the scum.

The disadvantage of the prototype is that the action of the cleaning discs on the head of the root crop is insufficient, because the side parts of the root crop head are not covered by the cleaning discs due to the very small time interval of their contact. Dry and lying remains of the brush, which are firmly held on the heads, and the root crops actually located (in between 3 rows) are not combed at all by this design of the cleaner. In addition, the discs come into contact with the heads of root crops only in the direction of the forward movement of the cleaner, and therefore the back sides of the heads generally remain uncleaned .

The invention sets the task of improving the quality of cleaning the heads of root crops from the remains of the gizzard on the root. with

The task set by the invention is achieved by the fact that in the cleaner of the root heads from the remains of the burdock on the root, which has a cantilever bearing element installed obliquely in the longitudinal-vertical plane, on the 7th end of which an active cleaning unit is installed, according to the invention, the cleaning unit consists of two, " -- installed in the transversal-vertical plane at an angle to each other brushes with fixed, perpendicular to their axes, flat elastic disks, and the upper ends of the brushes are connected to the drive reducer, which provides them with rotational movements in opposite directions.

Fig. 1 shows the scheme of the cleaner of the heads of root crops from the remains of the burdock on the root (side view). On

Fig. 2 shows view A in Fig. 1. "

The cleaner of the root heads from the remains of the scum on the root consists of a cantilever bearing element 1 installed obliquely in the longitudinal-vertical plane, at the end of which there is an active cleaning block consisting of two installed at an angle a to each other in the transverse-vertical plane

From" brushes 2 forming a cleaning channel. On the drive axes of brushes 2, flat elastic disks of different diameters are fixed perpendicularly, which increase in the downward direction. Elastic disks C are installed on the drive axles of brushes 2 with small gaps. The upper ends of the brushes 2 are connected to the drive gear 4 through gear wheels 5, which provide them with rotational movements in opposite directions. The directions of the rotary movements of the working bodies, as well as the direction of the translational movement of the cleaner, are shown by arrows. - The root vegetable head cleaner works as follows from the remains of the root. Moving gradually along the row of root crops, the heads of which have previously been cut off, but its remnants still remain, the cantilever bearing element 1 installed in the longitudinal and vertical plane directs the active cleaning unit 20 o'clock, formed by brushes 2 over the heads of root crops. Active cleaning unit, consisting of two installed in the transverse-vertical plane at an angle ozh; brushes 2, one to the other, cover each head of the root crop from two sides, and flat elastic discs 3, fixed perpendicular to the drive axes of the brushes 2, knock off the remains of the goo. At the same time, flat elastic discs Z bend and cover each head not only from two sides, but also from the front and back. The angle o, under which the brushes 2 are installed in the transverse-vertical plane, ensures full coverage of the heads of root crops of different sizes and shapes. Thanks to the driving force

GF) of the gearbox 4 and its gears 5, the directions of the rotational movements of the brushes 2 are opposite, which creates conditions 7 for a more guaranteed capture and subsequent separation of the green remains of the brush from the upper parts of the heads of root crops with elastic cleaning discs 3. Thanks to the different diameters of the elastic discs C, better cleaning of the side surfaces is achieved and lower parts of root heads. because the use of the proposed cleaner will improve the quality of cleaning the heads of root crops from the remains of scum on the root by 10...15905.
