Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically an integrated machine capable of rotary tillage, ditching, sowing, and compaction. Background Technology
[0002] Most existing single-unit seeding devices for rice, wheat, and small grains only have soil-dividing and furrowing mechanisms, which cannot achieve good depth-limited furrowing during sowing, resulting in inconsistent sowing depth and inconsistent emergence time. At the same time, with the change of rainy and dry seasons, the soil quality will also change, so the rolling pressure should also be adjusted according to the soil hardness. Most existing sowing devices do not have a mechanism to change the rolling pressure. Utility Model Content
[0003] The purpose of this invention is to provide an integrated rotary tillage, ditching, seeding, and compaction machine to solve the problems of stable ditching, seeding, and compaction.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary tillage, ditching, sowing, and compaction integrated machine, comprising front and rear support beams and a transverse support beam connected to each other, wherein a rotary tiller is rotatably connected to one end of the front and rear support beams, and a plurality of sowing leg mechanisms are installed on the transverse support beam;
[0005] The seeding box is mounted on the front and rear support beams via brackets. The two ends of the transverse support beams are provided with press roller mounting plates, and press rollers are mounted on the press roller mounting plates via connectors.
[0006] Compared with the prior art, the beneficial effects of this utility model are:
[0007] By incorporating seeding legs with furrowing discs, a suitable burial depth is achieved during seeding. A pair of rotating rods on the seeding legs create a four-bar linkage. An elastic element between the rotating rods allows the four-bar linkage seeding legs to easily return to their original position, adapting to uneven road surfaces.
[0008] By setting up a compaction structure that can adjust the compaction pressure, the seeds that have been furrowed and sown can be buried under reasonable pressure, ensuring that they can be planted properly under different soil hardness conditions. Attached Figure Description

[0014] 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.
[0015] Please see Figure 1-4 This utility model provides a technical solution: a rotary tiller, ditcher, seeder, and compactor integrated machine, including front and rear support beams 1 and a transverse support beam 5 connected to each other. A rotary tiller 2 is rotatably connected to one end of each of the front and rear support beams 1. A hydraulic cylinder 16 is rotatably connected to the rotary tiller 2, and the output end of the hydraulic cylinder 16 is rotatably connected to the cylinder pull beam of the front and rear support beams 1. This allows the working angle of the rotary tiller 2 to be adjusted according to the length of the output end of the hydraulic cylinder 16. In the no-load state, the hydraulic cylinder 16 shortens so that the rotary tiller 2 does not contact the ground; in the working state, the hydraulic cylinder 16 extends so that the rotary tiller 2 contacts the ground. A standing platform 3 is installed at the other end of each of the front and rear support beams 1 for the operator to stand on.
[0016] To facilitate sowing after rotary tillage, several sowing leg mechanisms are installed on the transverse support beam 5. Each sowing leg mechanism includes a main support leg 6, with a furrowing disc 7 installed at its bottom. The furrowing disc 7 creates furrows on the ground, facilitating subsequent sowing. One end of a pair of rotating connectors 8 is rotatably connected to the main support leg 6, and the other end of the pair of rotating connectors 8 is rotatably connected to a clamping seat 9, which engages with the transverse support beam 5. At this point, the main support leg 6, the rotating connectors 8, and the clamping seat 9 form a quadrilateral structure, allowing the main support leg 6 to move vertically, thus enabling the furrowing disc 7 to move normally even on uneven ground.
[0017] To allow the main support leg 6 to return to its initial position, an elastic element is provided between the pair of rotating connecting parts 8. This elastic element includes a spring 10 and a connecting rod 11 connected to each other. The connecting rod 11 has several openings 17. One side of the rotating connecting part 8 is connected to the spring 10, and the other side is connected to the openings 17 via a pin. By adjusting the connection position between the rotating connecting part 8 and the openings 17 on the connecting rod 11, the extension length of the spring 10 changes. This changes the elasticity of the elastic element between the pair of rotating connecting parts 8, thereby altering the return speed of the main support leg 6.
[0018] The clamping seat 9 includes a long clamping seat and a short clamping seat, which are arranged alternately. The sowing legs are also arranged alternately to ensure better sowing results.
[0019] The front and rear support beams 1 are equipped with a seeding box 4 for loading seeds. Several pipes can also be installed at the bottom of the seeding box 4, with the output end of the pipes aligned with the furrowing plate 7, so that the seeds can fall into the furrows opened by the furrowing plate 7.
[0020] The transverse support beam 5 has pressing roller mounting plates 15 at both ends, and pressing rollers 12 are mounted on the pressing roller mounting plates 15 via connectors. The connectors include roller support plates 13 and a pair of pressing roller rotating arms 14. The pressing rollers 12 are mounted on the roller support plates 13, and the roller brackets 13 are rotatably connected to the pressing roller mounting plates 15 via a pair of pressing roller rotating arms 14, so that the pressing rollers 12 can change their angle, thereby compacting the soil with different forces.
[0021] An angle adjustment mechanism is provided between the pressing roller mounting plate 15 and the pressing roller rotating arm 14. By adjusting the angle of the pressing roller 12, the contact force between the pressing roller 12 and the ground can be adjusted, thereby adapting to different soil conditions during the dry season or rainy season.
[0022] An angle adjustment mechanism is rotatably connected to the mounting plate 15 and the press roller rotating arm 14, respectively. It includes a pair of press roller adjusting plates 18, which are fixed to both sides of the press roller mounting plate 15. A wire drawing plate 19 is rotatably connected between the pair of press roller adjusting plates 18. Specifically, the tail end of each press roller adjusting plate 18 has an opening, and both ends of the wire drawing plate 19 are installed in this opening. A wire drawing rod 20 is inserted into the wire drawing plate 19. A nut is screwed onto one end of the wire drawing rod 20, and the nut restricts its movement on the wire drawing plate 19. A clamping plate is installed at the other end of the wire drawing rod 20, and the clamping plate is rotatably connected to the press roller rotating arm 14 via a pin.
[0023] Working principle: When the device is in the sowing state, the hydraulic cylinder 16 extends and the rotary tiller 2 contacts the ground, tilling the ground. The furrowing disc 7, located behind the rotary tiller 2, contacts the ground and opens furrows. At this time, the sowing box 4 sows seeds in the furrows. The seed channel is positioned directly opposite the furrowing disc 7, allowing the seeds to fall into the furrows opened by the furrowing disc 7.
[0024] To adjust the compaction and landfilling effect according to the soil conditions, simply rotate the nut to adjust the position of the nut on the wire-pulling rod 20 locked on the wire-pulling rotating plate 19. The compaction roller 12 compacts the ground after furrowing and sowing, thereby ensuring the sowing quality.
