Description

TECHNICAL FIELD

[0001] The utility model relates to soil ploughing machine technical field especially relates to a self -propelled pressure recommend leveler. BACKGROUND

[0002] Now the soil long -term use traditional ploughing can form ploughing bottom layer, influence soil's ventilation and water permeability. And driving type soil ploughing machine such as rotary hoe etc. can with its unique work mode, break ploughing bottom layer in soil, make the material and energy exchange between soil upper and lower layer more smooth, be favorable to crop root system's lower and growth.

[0003] Because existing driving type soil ploughing machine when using its rotary hoe as moving wheel uses, so ploughing relatively flat field, such as the application no. 202210281861.6 discloses a rear engine's front and rear drive ploughing machine, the driving type soil ploughing machine when driving in the uneven field, the rotary hoe will be due to the depression of the convex position on one side, causing the driving type soil ploughing machine on the same side of the two rotary hoe to lift at the same time, so that the driving type soil ploughing machine on the same side of the two rotary hoe to lift at the same time cannot be ploughed, and needs to plough the position repeatedly several times to make the convex position relatively flat with other positions, which will affect the efficiency of ploughing.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-5This utility model provides a self-propelled screed leveling machine, including two front rotating hoes 1 and two rear rotating hoes 2. A front connecting frame 3 is provided between the two front rotating hoes 1, which allows the two front rotating hoes 1 to rotate synchronously with a gap in horizontal alignment. A rear connecting frame 5 is provided between the two rear rotating hoes 2, which also allows the two rear rotating hoes 2 to rotate synchronously with a gap in horizontal alignment. A directional rotation structure 4 is provided above the front connecting frame 3, located above the space between the two front rotating hoes 1. The moving structure 4 adopts the directional rotation structure 4 used in existing tractors. A fixing plate 41 is provided on one side of the directional rotation structure 4. A connecting frame 6 is provided above the rear connecting frame 5. Two crossbeams 61 are symmetrically arranged on the side of the connecting frame 6 near the front rotating hoe 1. A fixing plate 62 is provided on the side of the two crossbeams 61 near the front rotating hoe 1. The fixing plate 41 and the fixing plate 62 are horizontally corresponding, and a rotating connection structure 7 is provided between them. The fixing plate 41 and the fixing plate 62 can be rotatably connected through the rotating connection structure 7.

[0021] This application provides an internal frame for a driven soil tiller. To form a complete driven soil tiller, an engine, operator's seat, directional control structure, and protective housings are added to the connecting frame 6 and two crossbeams 61. This application primarily addresses the synchronization between the front rotary hoe 1 and the rear rotary hoe 2. The front rotary hoe 1 and rear rotary hoe 2 are connected separately via a front connecting frame 3 and a rear connecting frame 5. The rear connecting frame 5 houses the connecting frame 6 for the engine and operator's seat, and two crossbeams 61. The front connecting frame 3 provides a directional control structure for controlling the movement of the front rotary hoe 1. Fixing plates 4 are then installed on the two crossbeams 61 and the directional control structure. 1. The fixed plate 41 and the fixed plate 62 are connected to form a whole. After the fixed plate 41 and the fixed plate 62 are connected by the rotating connection structure 7, the fixed plate 41 can rotate. In this case, when a front rotating hoe 1 presses down on a protruding position, the front wheels will always move first during the journey. So, basically, the front wheels will press down on the obstacle first. The fixed plate 41 will rotate on the rotating connection structure 7, so that the other rear rotating hoe 2 on the same side will not move synchronously with the raised rotating hoe. This reduces the impact of uneven positions in the field on cultivation and solves the problem in the prior art that when a driven soil tiller presses down on a protruding position, the other rotating hoe on the same side will be raised at the same time, which will affect the cultivation efficiency.

[0022] Preferably, two bow-shaped locking blocks 63 are symmetrically arranged on both sides of the second fixing plate 62. The two bow-shaped locking blocks 63 correspond to the two sides of the first fixing plate 41, and the rotation angle between the first fixing plate 41 and the second fixing plate 62 can be limited by the two bow-shaped locking blocks 63.

[0023] In this application, the bow-shaped locking block 63 can prevent the first fixing plate 41 from rotating too much when it rotates on the second fixing plate 62. When the first fixing plate 41 rotates too much, one side of the first fixing plate 41 will abut against the bow-shaped locking block 63, making it impossible to continue rotating.

[0024] Preferably, the rotating connection structure 7 includes a fixed shaft 71 and a locking pin 72. One end of the fixed shaft 71 is disposed on the second fixed plate 62, and the other end of the fixed shaft 71 extends through the first fixed plate 41 to the other side of the first fixed plate 41. The first fixed plate 41 is rotatably connected to the fixed shaft 71. The locking pin 72 is disposed on the other end of the fixed shaft 71, and the locking pin 72 prevents the first fixed plate 41 from falling off the fixed shaft 71.

[0025] In this application, the fixed shaft 71 is mainly used to connect the fixed plate 41 to the fixed plate 62 and enable the fixed plate 41 to rotate, while the locking pin 72 is used to lock the fixed plate 41 and prevent the connection between the fixed plate 41 and the fixed plate 62 from becoming loose.

[0026] Preferably, a rotating filler 73 is also provided on the fixed shaft 71, and the rotating filler 73 is located on the fixed shaft 71 between the fixed plate 41 and the fixed plate 62.

[0027] The rotating filler 73 is mainly used to fix the position between the first fixing plate 41 and the second fixing plate 62, so as to prevent the first fixing plate 41 from shaking due to the spacing between it and the second fixing plate 62 during the driving process.

[0028] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
