Abstract
Description
Technical Field
[0001] This utility model relates to the field of land preparation equipment technology, specifically an agricultural land preparation machine. Background Technology
[0002] Land preparation machines are important machines used in agricultural production for soil cultivation and land preparation. Their main function is to improve soil structure, remove debris, and level the land through a series of operations, creating a suitable soil environment for sowing, seedling cultivation, and crop growth.
[0003] Currently, tillage machines are generally attached to the tow rack at the rear of a tractor during operation. The tractor can typically only control the vertical lifting of the tillage machine, not its horizontal rotation. However, when tilling orchard land, a problem arises when the tillage machine needs to turn at the end between two rows of fruit trees to enter the next work area: the turning radius is large, making it easy for the rear of the tillage machine to scrape against the fruit trees during the turn, causing damage. Utility Model Content
[0004] This utility model provides an agricultural tillage machine to solve the problem mentioned in the background art: when a tractor-driven tillage machine is used to till orchard plots, and the tillage machine needs to turn at the end between two rows of fruit trees to enter the next working area, the turning radius is very large, which causes the rear end of the tillage machine to easily scrape against the fruit trees during the turning process, resulting in damage to the fruit trees.
[0005] To address the existing problems, this utility model provides an agricultural land preparation machine with a mounting frame. Connecting arms are fixedly connected to the lower surfaces of both ends of the mounting frame. A rotating shaft is rotatably connected to the lower end of each connecting arm, and multiple rake discs are fixedly connected to the rotating shaft. An adjustment mechanism is fixedly connected to the front end of the mounting frame. The adjustment mechanism includes a first crossbeam fixedly connected to the front end of the mounting frame. A hinge seat is fixedly connected to the middle front surface of the first crossbeam. One end of a movable arm is hinged to the hinge seat. The other end of the movable arm is fixedly connected to the middle rear surface of a second crossbeam. First fixing ears are symmetrically connected to the front surface of the second crossbeam. An extension frame is fixedly connected to the upper surface of the second crossbeam, and a second fixing ear is fixedly connected to the upper end of the extension frame. The lower surfaces of the first and second crossbeams are respectively hinged to the two ends of a hydraulic cylinder.
[0006] Furthermore, a reinforcing rod is fixedly connected between the movable arm and the second crossbeam.
[0007] Furthermore, a reinforcing frame is fixedly connected to the upper surface of the mounting frame and the first crossbeam.
[0008] Furthermore, the cylinder is connected to the tractor's hydraulic pump via an oil pipe.
[0009] Furthermore, the number of the hydraulic cylinders is two, and the two hydraulic cylinders are symmetrically distributed relative to the first crossbeam and the second crossbeam.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This invention, by setting up an adjustment mechanism, allows the tractor to turn at the end between two rows of fruit trees and enter the next working area. The mechanism controls the retraction of one cylinder on the inside of the turn and the extension of another cylinder on the outside of the turn. The pull and push of the two cylinders cause the mounting frame connected to the first crossbeam and its rear to rotate with the hinged seat at one end of the movable arm, thereby reducing the turning radius and preventing the rear end of the first mounting frame from scratching and damaging the fruit trees during the turn, thus overcoming the shortcomings of the prior art.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3An agricultural tillage machine includes a mounting frame 1. Connecting arms 2 are fixedly connected to the lower surfaces of both ends of the mounting frame 1. A rotating shaft 3 is rotatably connected to the lower end of the connecting arms 2. Multiple harrow discs 4 are fixedly connected to the rotating shaft 3. An adjustment mechanism 5 is fixedly connected to the front end of the mounting frame 1. The adjustment mechanism 5 includes a first crossbeam 501 fixedly connected to the front end of the mounting frame 1. A hinge seat 502 is fixedly connected to the middle front surface of the first crossbeam 501. One end of a movable arm 503 is hinged to the hinge seat 502. The other end of the movable arm 503 is fixedly connected to the middle rear surface of a second crossbeam 504. First fixing ears 505 are symmetrically connected to the front surface of the second crossbeam 504. An extension frame 506 is fixedly connected to the upper surface of the second crossbeam 504. A second fixing ear 507 is fixedly connected to the upper end of the extension frame 506. The lower surfaces of the first crossbeam 501 and the lower surfaces of the second crossbeam 504 are respectively hinged to the two ends of a hydraulic cylinder 508.
[0018] It should be noted that the telescopic rod of the hydraulic cylinder 508 has a certain extension range when it is installed. This is so that the telescopic rods of the two hydraulic cylinders 508 can extend and retract during the subsequent adjustment process of the adjustment mechanism.
[0019] A reinforcing rod 6 is fixedly connected between the movable arm 503 and the second crossbeam 504.
[0020] Among them, the upper surface of the mounting frame 1 and the first crossbeam 501 is fixedly connected with a reinforcing frame 7.
[0021] Among them, the hydraulic cylinder 508 is connected to the tractor's hydraulic oil pump via an oil pipe.
[0022] There are two hydraulic cylinders 508, which are symmetrically distributed with respect to the first crossbeam 501 and the second crossbeam 504.
[0023] Working principle: During operation, the agricultural tillage machine provided in this application is connected to the tractor's rear drawbar via the first fixed lug 505 and the second fixed lug 507. Then, the hydraulic cylinder 508 is connected to the tractor's hydraulic pump via an oil pipe. Initially, the extension of the two hydraulic cylinders 508 is the same. When the tractor needs to turn and turn around to enter the next working area between two rows of fruit trees during tillage, the hydraulic cylinder 508 on the inner side of the turn can be controlled to retract, and the hydraulic cylinder 508 on the outer side of the turn can be controlled to extend. Thus, the two hydraulic cylinders 508 pull and push, causing the hinge seat 502, which is fixedly connected to the front surface of the first crossbeam 501, to rotate at one end of the movable arm 503. This will drive the first crossbeam 501 and the mounting frame 1, which is fixedly connected to the first crossbeam 501, to rotate, thereby reducing the turning radius and preventing the rear end of the first mounting frame 1 from scratching and damaging the fruit trees when turning.
[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
