CS244319B1 - The device frame for a uniform cut of trees - Google Patents

Abstract

The frame according to the invention serves for adjusting the working strips to the working position, i.e. their extension and folding, which is controlled remotely directly from the tractor driver's seat. The essence of the invention is that two guides are connected to the frame body on the sides, onto which two slides are pushed. On each slide, hydraulic motors are rotatably connected next to each other on the upper part and electro-hydraulic distributors are installed in close proximity to them on the frame body. The quick-release fasteners surround the entire cross-section of the frame and hold the covers, which are attached to the frame body in the lower part.

BACKGROUND OF THE INVENTION The present invention relates to a frame for a uni-form cut of trees, particularly fruit, serving to adjust the working position of the working position, i. pulling them out and down.

So far known machines and devices are equipped with special booms, which are clearly complex, expensive and have a high weight. This is mainly true of the working rails by the mechanisms for their adjustment to the working position. Another known type of device uses a front loader instead of a special boom, which has a reduced stability and therefore a range of applications. All known types of devices are equipped with complex hydraulic systems for transferring power from the drive system to tools. Significant inertia from the tools is transmitted through the boom to the carrier, which is usually a tractor, thereby reducing the stability of the entire device.

The aforementioned drawbacks of the prior art are largely eliminated by the framework of the uniform tree cut according to the invention, the principle of which is that on the frame body there are two cross-sections T connected to the sides to which they are slip-on slip-on sliding door sliders, on each slider, the hydraulic motor sliding and the hydraulic motor for tilting are placed on top of each other;

The main advantages of the uni-form tree trimming frame according to the invention are that the arrangement of the frame makes it possible to adjust the working rails to the desired position, thereby adjusting and trimming the boundaries between the two rows and thus the rust crown of trees on one pass. The position of any of the two workbars by means of the devices located on both sides of the frame can be adjusted independently by dialing directly from the tractor driver's seat, without the assistance of another person. The device uses a front-end tilt for a special boom. Increasing the stability of the device is achieved by the complete frame hinged by the sub-hinge by which it attaches to the loaders as a counterweight, mainly by the vertical position of the work bars. Independent adjustment of the working rails is made possible by being fastened together with the hydromotors for tilting on the slides that move along the T-shaped guides.

The simplification and novelty of the hydraulic ring is achieved by the use of three-position electrohydraulic distributors which are mounted on the frame in close proximity to the consumers, thus reducing the number of hydraulic hoses between the appliances and the source only by the upstream and downstream branches. Also, the amount of oil pumped and the likelihood of environmental contamination are reduced. Possibilities of failures in adjusting mechanisms, e.g. falling off cutters, prevent newly formed covers with which the frame is provided.

1 is a front elevational view of the frame, FIG. 2 is a side view of the frame, and FIG. 3 is a side view of the frame. The frame of the uniform tree cutter is connected to the front end loader mounted on the tractor by means of quick couplers 13. The main supporting part is formed by a frame 1, at the top of which two T-shaped conduits 2 are fastened. By means of the hydraulic motors 4 for moving the slide pins 3, on which the working rails 14 are rotated together with the hydraulic motor, are guided by lines 2. 3 for folding and hydraulic locks 6. The operation of the appliances is remotely controlled by three-pole electro-hydraulic distributors. The movement of the hydraulic actuators 4 is controlled by the electrohydraulic ejection distributors 7, the movement of the hydraulic actuators 5 to control the electro-hydraulic tilting distributors 8, the movement of the tools on the working rails 14 is controlled by the electrohydraulic distributors 9 of the drive tools. The yoke-shaped fasteners 13 encircle the entire cross-section of the frame and serve to hold the covers that are attached to the frame in the lower part 1. The middle cover 10 serves mainly to cover the hydraulic motors 4 retracting, the hydraulic motors 5 for tilting, the e-electro-hydraulic distributors 7 and electrohydraulic 8-tilt distributors. The right cover 11 and the blank cover 12 serve mainly to cover the electrohydraulic tool drive 9 and the workbench mechanisms of the workbench 14. The frame of the uniform tree cutter according to the invention can be advantageously used in fruit production, where the cross-sections of the crowns of the trees planted in the rows and cut the sapracní aisle in the intersection to the necessary width.
