Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a rotary tillage ploughing device. Background Art

[0002] Increasing the application of organic fertilizers can effectively improve soil structure, regulate pH, increase soil microbial communities, and increase soil organic matter content. It is an effective way to improve soil, improve soil fertility, and solve soil acidification and compaction problems.

[0003] In the prior art, fertilizer spreaders are mostly used for fertilization. For liquid organic fertilizers, they can penetrate into the soil through their own osmosis to achieve the effect of fertilizing the soil. However, for solid organic fertilizers, fertilizer spreaders can only spread fertilizers on the soil surface and cannot effectively fertilize the soil in depth. The effect will be greatly reduced under the sun. In view of this, the applicant intends to develop a rotary tillage machine for deep mixing of solid organic fertilizers spread on the soil surface with the soil. Utility Model Content

[0004] In order to meet the above needs, the utility model provides a rotary tillage ploughing device, which is intended to mix solid organic fertilizer into the soil.

[0024] The utility model is further described below in conjunction with embodiments and drawings.

[0025] like Figures 1 to 3 As shown, a rotary tillage plowing device includes a vehicle body 1 and a rotary tillage assembly A installed at the rear end of the vehicle body 1, wherein the rotary tillage assembly A includes a rotary tillage bracket 2 extending along the width direction of the vehicle body 1 and a rotating shaft 3 rotatably installed at the lower part of the rotary tillage bracket 2, a rotary tillage blade group 4 is installed on the rotating shaft 3 along its axial array, and a driving assembly 5 is also installed on the outer side of the rotary tillage bracket 2, and the driving assembly 5 is used to drive the rotating shaft 3 to rotate, thereby allowing the rotary tillage blade group 4 to rotate. In this embodiment, the front end of the rotary tillage bracket 2 is hinged to the rear end of the vehicle body 1, and a hydraulic cylinder 6 is also connected between the vehicle body 1 and the rotary tillage bracket 2, and the two ends of the hydraulic cylinder 6 are respectively hinged at the middle position of the rear end of the vehicle body 1 and the middle position of the front end of the rotary tillage bracket 2. When the hydraulic cylinder 6 performs telescopic movement, it can control the rotary tillage bracket 2 to rotate relative to the vehicle body 1, so that the rotary tillage blade group 4 can be inserted downward into the soil.

[0026] With such a design, the rotary tillage assembly A is controlled to move downward by the hydraulic cylinder 6, so that the rotary tillage blade group 4 is inserted into the soil, the driving assembly 5 is started, and the vehicle body 1 pulls the rotary tillage assembly A to move, so that the soil and organic fertilizer can be crushed and mixed together, thereby making the organic fertilizer mixed more evenly.

[0027] In this embodiment, two sets of rubber tracks 1a are symmetrically installed at the bottom of the vehicle body 1. The rubber tracks 1a are particularly suitable for traveling in the land, and can provide greater traction and driving force, so that the rotary tillage assembly A can move more stably, thereby ensuring sufficient mixing of soil and organic fertilizer. Of course, a fertilizing device can also be directly integrated on the vehicle body 1, and the vehicle body 1 can complete the fertilization and rotary tillage mixing work at one time when traveling in the land.

[0028] like Figure 5 As shown, the rotary tillage support 2 includes a horizontally arranged main mounting plate 2a and side mounting plates 2b formed below the left and right sides of the main mounting plate 2a. The rotating shaft 3 is rotatably set between the two side mounting plates 2b, and the driving component 5 is fixedly installed on the outer side of one of the side mounting plates 2b. In this embodiment, the driving component 5 is a driving motor, and the driving motor drives the rotating shaft 3 to rotate directly or indirectly, thereby allowing the rotary tillage blade group 4 to rotate.

[0029] For example Figure 2 As shown, a mounting bracket 7 is provided at the middle position of the front end of the main mounting plate 2a, and the cylinder rod of the hydraulic cylinder 6 is hinged on the mounting bracket 7, and the cylinder barrel of the hydraulic cylinder 6 is hinged at the middle position of the rear end of the vehicle body 1. Connecting rods 8 are also hinged at the left and right ends of the mounting bracket 7, and the distal ends of the two connecting rods 8 are hinged at the rear end of the vehicle body 1. In actual use, the side of the hydraulic cylinder 6 close to the vehicle body 1 is affected by the deadweight of the rotary tillage assembly A and usually rests on the vehicle body 1. In this way, the connection between the vehicle body 1 and the rotary tillage assembly A is more stable, and it is ensured that when the hydraulic cylinder 6 is extended and retracted, it can drive the rotary tillage assembly A to rotate, thereby playing the function of adjusting the rotary tillage depth.

[0030] like Figure 3 and Figure 4 As shown, the rotary tiller blade group 4 includes two rotary tillers 4a both extending radially outward along the rotating shaft 3. The rotary tillers 4a of any two adjacent rotary tiller blade groups 4 are staggered, and the rotary tiller blade 4a has a curved section 4a1 located in a vertical plane, one end of the curved section 4a1 is fixedly connected to the rotating shaft 3, and the other end has a side curved section 4a2 that bends to the side. With such a design, the curved section 4a1 is arranged to facilitate the installation of the rotary tiller blade 4a, and the side curved section 4a2 is more conducive to breaking up the soil and fully mixing it with the organic fertilizer. The staggered arrangement of the rotary tillers 4a reduces the area of ​​the rotary tiller blade group 4 contacting the soil at the same time, thereby reducing the driving resistance when the vehicle body 1 pulls the rotary tiller assembly A to move.

[0031] like Figure 5As shown, a mudguard 2c is rotatably mounted on the rear end of the main mounting plate 2a, and a guide portion 2c1 inclined backward is formed at the bottom of the mudguard 2c. The mudguard 2c can effectively prevent the soil or organic fertilizer from splashing everywhere when the rotary tillage blade group 4 breaks the mixed soil and organic fertilizer; after the rotary tillage blade group 4 breaks the mixed soil and organic fertilizer, the guide portion 2c1 allows the land surface to remain flat.

[0032] Furthermore, a support rod 9 is hinged on the outer side of the bottom of the mud guard 2c, and a positioning hole 9a is arranged in an array at one end of the support rod 9 away from the hinge point. A positioning seat 2d is extended backward from the rear end of the main mounting plate 2a, and a pin is passed through the positioning hole 9a and the positioning seat 2d so that the rotation angle of the mud guard 2c can be fixed. In this embodiment, two support rods 9 are hinged on the outer side of the bottom of the mud guard 2c, and the mud guard 2c can be fixed more stably by the two support rods 9. With such a design, when the rotary tillage assembly A is rotary tilled at different depths, by passing the pin through different positioning holes 9a, it is ensured that the mud guard 2c can adaptively adjust the angle, and it can prevent soil or organic fertilizer from splashing everywhere without affecting the normal operation of the rotary tillage assembly A, and at the same time keep the surface of the land after rotary tillage flat.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
