Abstract

The purpose of the invention is to significantly reduce the cross-section of the entire device, reduce weight and increase the aesthetics of the structure. for feeding and catching cut branches. The purpose of the invention is achieved by placing pulleys with belts, which are protected by a system of covers, which are sliding and allow tensioning of the belts. It is advantageous to mount and dismantle individual working units, which are removably connected to the main beam and allow the connection of two types of tools, saw blades and knives.

Description

243764

The invention solves a device for a uniform pattern, in particular fruit, by means of which the crown-stems are cut into the desired shape.

Previously known devices have individual work rails equipped with different tool types depending on the thickness of the branches, and with rotating knives, saw blades or counter-knives. Up to now, known devices using special torque transfer parts for tools and tool gripping have a disproportionate weight. This weight does not adversely affect the stability of the device itself, the incuniform cut of the trees and thus the quality areas of the branches. Large masses of earlier devices are based on the cabinet structures of their main beams, where gears are located.

The disadvantages of the prior art are largely eliminated by the device for a uniform tree cut, the essence of which is that the center of the main beam from the side is a firmly retained support part of the hydraulic motor of the medium-drive working unit equipped with a hydro-motor, to which a belt-pulley of the motor with a wedge belt is attached, on either side moreover, slidingly connected side by side to the main beam are parts of driven working units to which bearing bolts attached by bolts are removably attached, which are provided with lubricating bearings from above, wherein bearings are pressed between bearing pins and reed belts. the respective working tools are attached to the pulleys, the supporting parts are provided with tensioning bolts with nuts, the rear covers are connected between the bearing parts and the hydromotor carrying part by bolts, the main beam, the supporting parts and the supporting part of the hydraulic motor are alternately sideways main beam and bush In addition, a top cover and a bottom cover attached thereto are attached to the other supporting portion, with the cover being provided with oval screw holes at the overlapping ends, the main barrel being provided with a strut.

If the working tool is a saw blade, higher saw blade holders and saw blade holders are alternately attached to the pulleys, and a saw blade holder on the hydraulic motor is attached to the hydraulic motor pulley, on which the threaded ends of the saw blades, the saw blades and the saw blades are inserted. pusher discs which are fastened by push-fit and centering nuts. If the working tool is a knife, higher knife holders and knife holders are connected to the pulleys alternately, and a knife holder is attached to the hydraulic motor pulley in which the knife is fixed.

The device described has a number of advantages which exert a higher effect of the invention. By arranging the work units according to the invention, their smaller and narrower cross-section has been achieved by a smooth aesthetic design compared to the known devices. The aforementioned slimness of the working units avoids the thumping and trapping of cut branches. A further advantage is that the radial load of the hydraulic motor shaft is equal from both sides, because the hydraulic motor is located at the center of the working units. their stretching. New and very advantageous installation of individual blocks which are removably connected to the main beam, which makes it easy to assemble, disassemble and replace components during repairs. Among the advantages of the device is that it is possible to use and alternatively replace two types of tools, namely saw blades and rotary blades, thereby allowing the trees to be cut through the stub and rough branches with a single device instead of the two previously needed. drive belt and toolholder in one block, the drive belt tensioning system is selected to reduce the weight of the device. By reducing the weight of the device, stability and also the quality of the gray felt on the legs are improved. Examples of embodiments of the device according to the invention are shown in the accompanying drawings. Naobr. 1 is an elevational view of the device, FIG. 2 is a side view thereof, FIG. 3 shows a second side view of FIG. Fig. 4 shows a saw blade working unit in section A-A of Fig. 2; Fig. 5 is a sectional view of the saw blade drive unit shown in section B-B of Fig. 2; is shown in section B'— B ' 2 shows the driven working unit with a knife.

The device for uniformly cutting trees, especially fruit trees, consists of at least three or more working units which are exchangeable and either saw blades 18 or blades 11 can be used as a working tool.

On the main beam 1, a support portion 23 of the driving motor of the driving unit, on which the hydraulic motor 9 is attached, is fixedly fixed to the central beam 1 by means of a tongue 19, which is bolted to the main beam by screws. the retained support parts 20 of the driven work units on each support portion 20 are screw-connected to the support pin 22, from the top provided by the thrust head 27 such that through the axis of the support pin 22 the lubricant is conveyed to the bearing 29 on which the pulley 24 is mounted. the moment from the pulley 19 is transmitted to the other pulley 24 by means of wedge-shaped wedges 26. The supporting parts 20 of the driven working units are provided with oval options in the contact surfaces with the main beam 1, allowing the tensioning of the belts 26 by means of a tensioning screw 3 after loosening the connecting bolts. which is secured by a nut 2 after tension
