Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, specifically to a staggered-row tillage device. Background Technology

[0002] "Staggered-row cultivation" is a conservation tillage method that involves alternating the planting rows of crops over two consecutive years to avoid planting crops continuously in the same location on the same plot of land. Its core purpose is to balance soil nutrient consumption and prevent localized soil fertility decline or specific nutrient deficiencies caused by prolonged planting in the same row. It also reduces the breeding and accumulation of soil-borne pests and diseases, mitigating their sustained impact on crops. Furthermore, it improves soil structure by adjusting the topsoil layer through row staggering, reducing soil compaction, and enhancing soil aeration and water retention. The specific process involves: in the first year, selecting appropriate row spacing for ridging and plowing; after sowing and harvesting, leaving the roots and stubble in the soil after stubble removal to increase soil organic matter content. In the second year, the ridge positions of the first year are used as a reference, and the new ridge positions are staggered from the old ridge positions, so that the position of the new ridge is between the two ridges of the first year. At present, although the advantages of staggered ridge farming are obvious, it is necessary to first remove stubble, and then select a position and plow to form a new ridge position. This makes the farming process complicated, time-consuming, and increases the cost of farming. Therefore, we propose a staggered ridge farming device. Utility Model Content

[0003] The purpose of this invention is to provide a staggered-row tillage device to solve the problems mentioned in the background art.

[0004] A staggered-row tillage device includes a crossbeam, with connecting frames installed at both ends of the crossbeam. A rotary tillage device is installed at the lower end of the connecting frames. Two connecting plates are symmetrically installed below the middle position of the crossbeam, and a rotating shaft is connected between the connecting plates. The two ends of the rotating shaft pass through the connecting plates and are connected to the rotary tillage shaft of the rotary tillage device. A transmission gear is also installed on the rotating shaft. The transmission gear is connected to the output shaft of a tractor or other traction device through a bevel gear transmission box. The transmission direction is changed through the bevel gear transmission box, so that the output shaft of the traction device drives the transmission gear and the rotating shaft to rotate. A connecting tube is detachably installed on the rotating shaft. The connecting tube can slide and adjust its position on the rotating shaft. Several stubble-cutting claws are provided on the outer surface of the connecting tube. A traction frame is installed at the upper end of the crossbeam, facing forward. A third connecting hole is provided on the traction frame.

[0005] Preferably, both ends of the rotating shaft are inserted into bearings provided on the connecting plate, and the bearings are bearing retaining bearings to limit the axial movement of the rotating shaft.

[0006] Preferably, the rotating shaft has a plurality of first connecting holes, and the connecting tube has a second connecting hole in the middle. A connecting bolt is inserted into the first connecting hole and the second connecting hole, and a connecting nut is screwed to the lower end of the connecting bolt, so that the rotating shaft and the connecting tube are connected by the connecting bolt and the connecting nut, which facilitates disassembly and assembly.

[0007] Preferably, a plurality of rotary tillage claws are installed on the outside of the rotary tillage shaft, the middle of the rotary tillage shaft is sleeved inside the shaft sleeve, and the shaft sleeve is installed at the lower end of the connecting frame.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] When cultivating staggered ridges, the connecting tube is aligned with the existing ridge position, and the two rotary tillers correspond to the ridge positions on both sides. Then, the tractor or other tractor is connected to the third connecting hole on the tractor frame. The transmission gear on the rotating shaft is connected to the output shaft of the tractor through a bevel gear transmission box. When the tractor drives the device forward, the output shaft of the tractor drives the transmission gear and the rotating shaft to rotate, which in turn drives the rotary tillers, connecting tube, and stubble-removing claws to rotate, breaking up and turning over the stubble on the existing ridge position. The two rotary tillers at both ends move forward to turn over the stubble, simultaneously completing the stubble removal and turning over, thus improving the efficiency of staggered ridge cultivation and reducing costs.

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] See Figure 1-3 A staggered-row tillage device includes a crossbeam 1, with connecting frames 2 installed below both ends of the crossbeam 1. A rotary tillage device 3 is installed at the lower end of the connecting frames 2. Two connecting plates 4 are symmetrically installed below the middle position of the crossbeam 1, and a rotating shaft 5 is connected between the connecting plates 4. Both ends of the rotating shaft 5 extend through the connecting plates 4 and connect to the rotary tillage shaft 32 of the rotary tillage device 3. Both ends of the rotating shaft 5 are inserted into bearings 9 provided on the connecting plates 4. The bearings 9 are bearing stop bearings, which limit the axial movement of the rotating shaft 5. A transmission gear 8 is also installed on the rotating shaft 5. The transmission gear 8 on the rotating shaft 5 is connected to the output shaft 15 of a tractor through a bevel gear transmission box 14. When the tractor drives the device forward, the output shaft 15 of the tractor drives the transmission gear 8 and the rotating shaft 5 to rotate. A connecting shaft 6 is detachably installed on the shaft 5. Several first connecting holes 501 are provided on the shaft 5. A second connecting hole 601 is provided in the middle of the connecting shaft 6. A connecting bolt 12 is inserted into the first connecting hole 501 and the second connecting hole 601. A connecting nut 13 is screwed to the lower end of the connecting bolt 12, so that the shaft 5 and the connecting shaft 6 are connected by the connecting bolt 12 and the connecting nut 13, which facilitates disassembly and assembly. Several stubble-killing claws 7 are provided on the outer surface of the connecting shaft 6. When cultivating in staggered rows, the connecting shaft 6 is aligned with the existing ridge position. A traction frame 10 is installed on the upper end of the crossbeam 1. The traction frame 10 faces forward. A third connecting hole 11 is provided on the traction frame 10. During operation, the tractor is connected to the third connecting hole 11 on the traction frame 10.

[0016] Working principle: During staggered ridge cultivation, the connecting tube 6 is aligned with the existing ridge, and the two rotary tillers 3 correspond to the ridges on both sides. The tractor or other tractor is then connected to the third connecting hole 11 on the tractor frame 10. The transmission gear 8 on the rotating shaft 5 is connected to the output shaft 15 of the tractor through the bevel gear transmission box 14. When the tractor drives the device forward, the output shaft 15 of the tractor drives the transmission gear 8 and the rotating shaft 5 to rotate, which in turn drives the rotary tillers 3, the connecting tube 6, and the stubble-removing claw 7 to rotate, breaking up and turning over the stubble on the existing ridge. The two rotary tillers 3 at both ends move forward to turn over the stubble. After the stubble removal is completed, the two adjacent ridges are also turned over synchronously, and then cultivation is carried out on the new ridge.
