Description

Technical Field

[0001] The utility model belongs to the field of tillage agricultural machinery, and in particular relates to a saline-alkali land tillage machine. Background Art

[0002] Soil evaporation in farmland not only causes ineffective loss of soil moisture, but also causes problems such as soil salinization, exacerbating the contradiction between water shortage and crop production. Covering with mulch can reduce ineffective soil evaporation, save water and also have a good effect on preventing soil salinization. However, the traditional film covering method will break the film during the later tillage operation. Although some large pieces of residual film can be removed, small pieces of residual film will be broken into pieces in the soil. This method will cause soil microplastic pollution. On the other hand, the film has a short service life and needs to be re-laid after each crop harvest, resulting in waste of mulch. Another mulching method is to use thicker mulch to lay in the field, roll up the mulch during tillage operation, and lay the mulch again after tillage is completed. This mulching method can reduce microplastic pollution, but it requires a lot of manpower. In the prior art, there is a rotary tiller that extends a rotary tilling shaft under the ground film for operation, but the far end of the rotary tilling shaft is suspended in the air, which is prone to vibration during operation. At the same time, it is greatly affected by the resistance of the soil and the rotary tilling shaft is easily damaged. Therefore, how to reduce the vibration of the working shaft, extend the service life of the working shaft, and improve the working effect is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0003] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a saline-alkali land tiller, which can turn the land under the ground film. The connection between the tilling shaft and the drive box is more stable, which can effectively reduce the vibration of the tilling shaft and extend the service life of the tilling shaft.

[0004] The specific technical solution adopted by the utility model is:

[0005] A soil turning machine for saline-alkali land comprises a frame connected to a tractor and a soil turning assembly arranged on the frame, the key point being that the soil turning assembly is arranged on the side of the frame, and comprises a driving box located below the ground film, a support plate at one end of which is connected to the driving box, and a soil turning shaft located in front of the support plate, the angle between the axis of the soil turning shaft and the traveling direction of the tractor is set to be an acute angle, the front end of the soil turning shaft is connected to the driving box, the rear end of the soil turning shaft and the other end of the support plate are respectively connected to a mounting frame, and the front end of the driving box and the front end of the mounting frame are respectively provided with a ridge-shaped soil breaking shovel.

[0006] One end of the drive box is hinged to the frame by means of an articulated shaft, and a telescopic rod for adjusting the pitch angle of the drive box relative to the ground is arranged between the other end and the frame. The axial direction of the articulated shaft is arranged horizontally and perpendicular to the traveling direction of the tractor.

[0007] The tilling shaft is drivingly connected to the transfer case on the frame by means of a driving box, and the power input shaft of the transfer case is connected to the power output end of the tractor.

[0008] The drive box is connected to the transfer case on the frame by means of a first transmission shaft coaxially arranged with the hinge shaft. A second transmission shaft connected to the tiller shaft is arranged in the drive box. The second transmission shaft is located below the first transmission shaft and is arranged parallel to the first transmission shaft.

[0009] The support plate is in an inclined shape with a low front and a high rear along the traveling direction of the tractor.

[0010] Ground turning components are respectively arranged on both sides of the frame.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-5 The tiller 2 is a soil-turning machine for saline-alkali land, comprising a frame 1 connected to a tractor and a tiller assembly 2 arranged on the frame 1. The key point is that the tiller assembly 2 is arranged on the side of the frame 1, and the tiller assembly 2 comprises a driving box 3, a supporting plate 4 and a tiller shaft 5 located below the ground film 15. The angle between the axis of the tiller shaft 5 and the walking direction of the tractor is set at an acute angle. The front end of the tiller shaft 5 and one end of the supporting plate 4 are respectively connected to the driving box 3, and the rear end of the tiller shaft 5 and the other end of the supporting plate 4 are respectively connected to the mounting frame 6; the tiller shaft 5 is tilted to effectively reduce the resistance of the soil to the tiller shaft 5 during the walking process of the tractor, and the working performance of the tiller shaft 5 is more stable; the tiller shaft 5 is located in front of the supporting plate 4, and forms a closed-loop structure with the driving box 3, the supporting plate 4 and the mounting frame 6; the front end of the driving box 3 and the front end of the mounting frame 6 are respectively provided with a ridge-shaped soil-breaking shovel 7, the tiller assembly 2 is arranged on the side of the frame 1, and the frame 1 is The mulch film 15 moves outside, and the driving box 3, the mulch shaft 5 and the support plate 4 in the mulch assembly are located under the mulch film 15 to mulch the soil. The soil-breaking shovel 7 scratches the soil to facilitate the driving box 3 and the mounting frame 6 to move forward with the movement of the tractor. During the forward movement, the mulch shaft 5 rotates, and the mulch blade head thereon breaks up and mulches the soil. The mulch shaft 5 forms a closed-loop structure with the support plate 4, the driving box 3 and the mounting frame 6, which significantly improves the stability of the mulch shaft 5 when working under the mulch film 15, increases the connection strength, and effectively prevents the mulch shaft 5 from vibrating during work. The mulch shaft 5 and its mounting assembly are not easy to be damaged, and their service life is extended. When the mulch machine is used for mulch operations, there is no need to roll up and re-lay the mulch film 15, which reduces manual labor and does not break the mulch film 15, thereby extending the service life of the mulch film 15 and reducing the pollution of microplastics in the soil. The mulch film 15 can be covered in the field all year round, effectively inhibiting the evaporation of water in the soil and returning salt.

[0021] Furthermore, one end of the driving box 3 is hinged to the frame 1 by means of an articulated shaft 8, and a telescopic rod 9 is arranged between the other end and the frame 1 for adjusting the pitch angle of the driving box 3 relative to the ground. The axial direction of the articulated shaft 8 is arranged horizontally and perpendicular to the traveling direction of the tractor. In this embodiment, the telescopic rod 9 is a hydraulic cylinder. By adjusting the length of the telescopic rod 9, the pitch angle of the driving box 3 relative to the ground can be changed, so that the soil-breaking shovel 7 arranged at the front end is tilted and inserted into the soil downward, and the tilling shaft 5 works to break the soil. The frame 1 is connected to the tractor through a three-point suspension, and the frame 1 is pressed down by the three-point suspension of the tractor, and the tractor moves forward, so that the driving box 3, the tilling shaft 5, and the support plate 4 extend into the soil under the ground at an inclined angle. When the preset depth is reached, the telescopic rod 9 makes the driving box 3 horizontal, and the tractor continues to move forward. The soil-breaking shovel 7 cuts the soil under the ground film 15, and the tilling shaft 5 breaks and turns the soil to complete the tilling operation.

[0022] Furthermore, the tilling shaft 5 is transmission-connected to the transfer case 10 on the frame 1 by means of the drive box 3, and the power input shaft of the transfer case 10 is connected to the power output end of the tractor.

[0023] Among them, the drive box 3 is connected to the transfer case 10 on the frame by means of a first transmission shaft 11 coaxially arranged with the hinge shaft 8. When the drive box 3 adjusts the pitch angle by means of the telescopic rod 9, the continuity of transmission can be maintained to avoid jamming. A second transmission shaft 12 connected to the tilling shaft 5 is arranged in the drive box 3. The second transmission shaft 12 is located below the first transmission shaft 11 and is arranged parallel to the first transmission shaft 11. The telescopic rod 9 is located behind the second transmission shaft 12. The transmission of the second transmission shaft 12 and the first transmission shaft 11 is not affected by the change in the pitch angle of the drive box 3, thereby ensuring the stability during the tilling operation; the front end of the tilling shaft 5 is connected to the second transmission shaft 12 by means of a pair of bevel gears 14, and the direction of power transmitted from the second transmission shaft 12 to the tilling shaft 5 is changed by means of the bevel gears 14, so that the tilling shaft 5 is inclined, thereby reducing the resistance of the soil to the tilling shaft 5 during the walking process of the tractor, and the working performance of the tilling shaft 5 is more stable.

[0024] Furthermore, the support plate 4 is inclined with a low front and a high rear along the traveling direction of the tractor. During the movement of the tractor, the support plate 4 with a low front and a high rear is pressed into the ground by the downward pressure of the soil in front, providing a stable supporting force for the tillage shaft 5, further preventing the tillage shaft 5 from vibrating, and ensuring that the tillage shaft 5 works smoothly.

[0025] Soil turning components 2 are respectively arranged on both sides of the frame 1. The two sides of the frame 1 are balanced and stable, and soil turning operations can be performed on the soil on both sides of the frame 1 at the same time, thereby improving work efficiency.
