Abstract

The present invention discloses a soil-turning device for agricultural planting, which relates to the technical field of agricultural machinery and includes a mobile vehicle body. An installation groove is formed through the top of the mobile vehicle body, and a driving motor is fixedly installed on the outer wall of one side of the mobile vehicle body. A soil-crushing cylinder is arranged inside the installation groove. When this soil-turning device for agricultural planting is performing soil-turning operations, the driving motor drives three digging buckets to continuously dig the soil, and through the cooperation of large and small gears, the powder fragments in the soil-crushing cylinder are driven to crush the soil, quickly realizing the fragmentation and screening of the soil, ensuring that the soil is loose and uniform, and facilitating subsequent agricultural operations. At the same time, the sieve plate blocks the stones. By using the cooperation of the driving and driven gears, when the digging bucket rotates a specific angle, the cross bar drives the staggered inclined bars to pop the stones to the surface layer, avoiding the stones from damaging the soil structure, and using the stones to increase the surface roughness of the soil, improving the wind and water resistance of the soil, reducing soil erosion, and maintaining the fertility and structural stability of the soil.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, in particular to soil turning equipment for agricultural planting. Background Art

[0002] Tilling is a soil cultivation method commonly known as ploughing, plowing, or ploughing, which involves shoveling, breaking up, and turning over soil using farm implements such as a plow. It has a long and widespread history in global agriculture. China began using plows with sidewalls to till the land over 2,000 years ago. Tilling involves shoveling, breaking up, and dredging the soil to make it flat and loose. It is the initial step in farming, allowing seeds to breathe and grow easily in the soil. It has been a common farming method used in both northern and southern China for thousands of years, and it remains the only unified method used in both regions. Currently, tilling is largely mechanized.

[0003] At present, although agricultural tillers have the function of crushing soil when plowing the soil, the structure of their crushing mechanism is simple, consisting of only a few pointed rods. Especially when plowing soils with high density such as clay and heavy loam, multiple plowings are often required to achieve the ideal soil crushing effect, which not only increases the operating cost, but also prolongs the operating time and reduces the overall efficiency. In addition, when plowing the soil, the tiller often encounters stones on the soil surface. When the blades or plowshares of the tiller cut into the soil, these stones are easily drawn into it and buried in the soil as the tilling action deepens, so that the stones occupy the effective space in the soil, reduce the porosity of the soil, thereby affecting the air permeability and water retention capacity of the soil, which is not conducive to agricultural planting.

Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Example 1, please refer to Figure 1-7 , the present invention provides a soil turning device for agricultural planting, including a mobile vehicle body 1. An installation groove 2 is penetrated and opened at the top of the mobile vehicle body 1, and a driving motor 3 is fixedly installed on an outer wall of one side of the mobile vehicle body 1. A soil crushing cylinder 4 is arranged inside the installation groove 2, and excavation buckets 5 are fixedly connected to the outer wall of the soil crushing cylinder 4 at equal intervals.

[0029] A soil excavation and crushing component 6 is arranged inside the soil crushing cylinder 4.

[0030] Furthermore, the soil-breaking component 6 includes two shaft columns 601. The end portions of the two shaft columns 601 close to each other are fixedly connected to the centers of the two end faces of the soil-breaking cylinder 4. One end portion of one shaft column 601 away from the soil-breaking cylinder 4 is rotatably connected to the inner wall of the installation groove 2, and one end portion of the other shaft column 601 away from the soil-breaking cylinder 4 is fixedly connected to the output shaft of one end of the driving motor 3. A soil-breaking cavity 602 is formed inside the soil-breaking cylinder 4, and communication grooves 603 are equidistantly formed through the outer wall of the soil-breaking cylinder 4 corresponding to the excavation buckets 5. A collection cavity 604 is formed inside the inner wall of the excavation bucket 5, and the inner wall of the collection cavity 604 is communicated with the soil-breaking cavity 602 through the communication grooves 603. Connection grooves 605 are equidistantly formed through the two end faces of the soil-breaking cylinder 4, and the number of connection grooves 605 on the two end faces of the soil-breaking cylinder 4 is three. Shaft rods 606 are rotatably connected to the inner walls of the three connection grooves 605. Small gears 607 are fixedly connected to the outer walls of the two end portions of the three shaft rods 606. Large gears 608 are rotatably connected to the outer walls of the two shaft columns 601 corresponding to the small gears 607. The large gears 608 are meshed with the small gears 607.

[0031] More specifically, when turning the soil, first, push the equipment to move to the position where the soil needs to be turned. Then, since the end portions of the two shaft columns 601 close to each other are fixedly connected to the centers of the two end faces of the soil-breaking cylinder 4, one end portion of one shaft column 601 away from the soil-breaking cylinder 4 is rotatably connected to the inner wall of the installation groove 2, and one end portion of the other shaft column 601 away from the soil-breaking cylinder 4 is fixedly connected to the output shaft of one end of the driving motor 3, the soil-breaking cylinder 4 can be driven to rotate by the driving motor 3. Then, since the excavation buckets 5 are fixedly connected to the outer wall of the soil-breaking cylinder 4 at equal intervals, a soil-breaking cavity 602 is formed inside the soil-breaking cylinder 4, communication grooves 603 are equidistantly formed through the outer wall of the soil-breaking cylinder 4 corresponding to the excavation buckets 5, a collection cavity 604 is formed inside the inner wall of the excavation bucket 5, and the inner wall of the collection cavity 604 is communicated with the soil-breaking cavity 602 through the communication grooves 603, the soil can be excavated by the rotating soil-breaking cylinder 4 driving multiple excavation buckets 5. After the excavation buckets 5 excavate the soil, the soil can fall into the soil-breaking cavity 602 from the collection cavity 604 along the way during the subsequent circular movement of the excavation buckets 5.

[0032] Next, connecting grooves 605 are equidistantly perforated through both end faces of the soil-breaking cylinder 4, and the number of connecting grooves 605 on both end faces of the soil-breaking cylinder 4 is three. Shaft rods 606 are rotatably connected to the inner walls of the three connecting grooves 605. At both ends of the outer walls of the three shaft rods 606, small gears 607 are fixedly connected. At the same time, large gears 608 are rotatably connected to the outer walls of the two shaft columns 601 corresponding to the small gears 607. The large gears 608 are meshed with the small gears 607. At the end faces of the large gears 608 away from each other, limiting columns 609 are fixedly connected. At the same time, the other ends of the limiting columns 609 are fixedly connected to the inner wall of the installation groove 2. Thus, during the rotation of the soil-breaking cylinder 4, the three shaft rods 606 can be synchronously driven to move in a circular motion around the shaft column 601. At this time, the large gears 608 are restricted by the limiting columns 609. When the three small gears 607 are meshed with the large gears 608, since the large gears 608 cannot rotate, the three small gears 607 moving in a circular motion around the large gears 608 can rotate, and further, the three shaft rods 606 during the circular motion can rotate on their own axes.

[0033] Next, pulverizing pieces 610 are equidistantly fixedly connected to the outer wall of the shaft rod 606 corresponding to the soil-breaking cavity 602. Thus, the several pulverizing pieces 610 in the soil-breaking cavity 602 can be driven by the three shaft rods 606 to break up the caked soil falling into the soil-breaking cylinder 4, ensuring the degree of fragmentation and looseness of the soil, improving the fineness and uniformity of the soil, and laying a good foundation for subsequent agricultural operations such as sowing and fertilizing.

[0034] Next, sieve holes 611 are equidistantly perforated through the outer wall of the soil-breaking cylinder 4 corresponding to the soil-breaking cavity 602. Thus, the rotating soil-breaking cylinder 4 can be used to roll and screen the pulverized soil. During the rotation of the soil-breaking cylinder 4, the soil particles are evenly distributed in the cylinder, and the soil particles are subjected to the action of centrifugal force in the soil-breaking cylinder 4, which helps the particles pass through the sieve holes 611 faster and improves the screening efficiency.

[0035] Through the above, when turning the soil, the three digging buckets 5 can be driven by the drive motor 3 to connect and dig and collect the soil. At the same time, through the cooperation of the large gears 608 and the small gears 607, the several pulverizing pieces 610 in the soil-breaking cylinder 4 can break up the collected soil. Thus, the caked soil can be quickly broken up. At the same time, through the cooperation of the rotating soil-breaking cylinder 4 and the sieve holes 611, the broken soil can be screened, ensuring the degree of fragmentation and looseness of the soil, improving the fineness and uniformity of the soil, and laying a good foundation for subsequent agricultural operations such as sowing and fertilizing.

[0036] Embodiment 2, on the basis of the above embodiment, a stone removing component 7 is arranged inside the digging bucket 5.

[0037] Further, the stone removing component 7 includes a rotating rod 701, and openings for the rotating rod 701 to penetrate are formed in the outer walls on both sides of the digging bucket 5. The inner wall of the opening is rotatably connected to the outer wall of the rotating rod 701 through a bearing. Driven gears 702 are fixedly connected to both ends of the rotating rod 701. Support plates 706 are symmetrically and fixedly connected to the top of the moving vehicle body 1. A rotating column 704 is rotatably connected to the side walls of the two support plates 706 close to each other. Driving gears 705 are fixedly connected to the ends of the two rotating columns 704 close to each other corresponding to the driven gears 702, and the driving gears 705 are meshed and matched with the driven gears 702. A pulley transmission mechanism 703 is arranged between the shaft column 601 and the outer wall of the rotating column 704. The shaft column 601 and the rotating column 704 are connected through the pulley transmission mechanism 703. Cross bars 707 are symmetrically arranged on the outer wall of the rotating rod 701. The two ends of the two cross bars 707 are in sliding contact with the inner wall of the collecting cavity 604.

[0038] More specifically, a sieve plate 612 is fixedly connected to the inner wall of the collecting cavity 604 corresponding to the stone removing component 7, so as to screen the excavated soil, block and retain the stones in the soil, and prevent them from falling into the soil crushing cylinder 4 and damaging the powder fragments 610. Then, when a certain digging bucket 5 is vertically downward, it represents the deepest point of the soil excavation at this time. When the digging bucket 5 continues to rotate by 90 degrees, the digging bucket 5 is horizontally oriented at this time, which represents the completion of the excavation. The soil accumulates in the collecting cavity 604 of the digging bucket 5. At this time, the digging bucket 5 continues to rotate by 90 degrees, that is, during the process of changing from the horizontal orientation to the vertical upward orientation, the soil in the collecting cavity 604 will continuously fall into the soil crushing cylinder 4 under the action of gravity for the crushing step.

[0039] When the digging bucket 5 is vertically upward, only the blocked stones accumulate in the collecting cavity 604 at this time. At this time, the two ends of the rotating rod 701 pass through the inside of the digging bucket 5 and extend to the outside of the digging bucket 5, and driven gears 702 are fixedly connected to the two extended ends of the rotating rod 701. At the same time, the shaft column 601 and the rotating column 704 are connected through the pulley transmission mechanism 703. Driving gears 705 are fixedly connected to the ends of the two rotating columns 704 close to each other corresponding to the driven gears 702, and the driving gears 705 are meshed and matched with the driven gears 702. Thus, when the digging bucket 5 moves to the vertical upward position, the driven gear 702 will be synchronously driven to contact and mesh with the rotating driving gear 705, causing the rotating rod 701 to rotate.

[0040] Next, cross bars 707 are symmetrically arranged on the outer wall of the rotating rod 701, and both ends of the two cross bars 707 are in sliding contact with the inner wall of the collection chamber 604. Through holes 708 are formed through the interiors of the two cross bars 707, and the inner wall of the through hole 708 is in sliding contact with the outer wall of the rotating rod 701. Helical grooves 709 are symmetrically formed on the outer wall of the rotating rod 701, and the helical directions of the helical grooves 709 are opposite. Slide beads 710 are fixedly connected to the inner wall of the through hole 708 corresponding to the helical grooves 709, and the outer wall of the slide bead 710 is in sliding contact with the inner wall of the helical groove 709. Therefore, during the rotation of the rotating rod 701, by means of the cooperation between the helical groove 709 and the slide bead 710, and the rotation restriction of the cross bar 707 by the collection chamber 604, when the cross bar 707 cannot rotate, the two cross bars 707 can be driven to move closer to each other synchronously.

[0041] Next, a number of staggered diagonal rods 711 are fixedly connected to the side walls of the two cross bars 707 at equal intervals. One ends of the number of staggered diagonal rods 711 away from the cross bars 707 are in sliding contact with the inner wall of the collection chamber 604. Therefore, the two cross bars 707 moving closer to each other quickly can drive a number of staggered diagonal rods 711 arranged on both sides to move, and the inclined planes can be used to guide the stones to move out of the collection chamber 604. Thus, under the rapid approach of the two cross bars 707, the retained stones can be ejected from the collection chamber 604 and fall on the soil surface layer. On the one hand, it can prevent the stones on the surface layer or inner layer from being turned back into the inner layer of the soil, resulting in damage to the soil structure. On the other hand, the stones covering the soil surface layer can be used to increase the roughness of the soil surface and improve the resistance of the soil to wind and water flow.

[0042] Next, a return torsion spring 712 is arranged in a fitting manner on the outer walls of the two extended ends of the rotating rod 701. One end of the return torsion spring 712 is fixedly connected to the outer wall of one side of the digging bucket 5, and the other end of the return torsion spring 7M2 is fixedly connected to the outer wall of the extended end of the rotating rod 701. Therefore, when the driven gear 702 is in contact and engaged with the driving gear 705, the rotating rod 701 at this time can compress the return torsion spring 712 elastically. When the two cross bars 707 are in contact with each other, at this time the driven gear 702 and the driving gear 705 are disengaged from each other. At this time, the return elastic force of the return torsion spring 712 can be used to drive the rotating rod 701 to reverse, so that the two cross bars 707 return to the initial position to wait for the next time to eject the stones.

[0043] Next, protective shells 713 are fixedly connected to the outer walls of both sides of the digging bucket 5 corresponding to the driven gear 702, so that the protective shells 713 can be used to protect the driven gear 702 on the digging bucket 5 and prevent the driven gear 702 from coming into direct contact with the soil during the digging process.

[0044] Through the above, when turning the soil, the sieve plate 612 can block and retain the stones in the collected soil. At the same time, through the cooperation of the driving gear 705 and the driven gear 702, when the excavation bucket 5 rotates to a certain angle, the two cross bars 707 can drive the staggered diagonal bar 711 to eject the retained stones from the collection chamber 604 and fall on the soil surface. On the one hand, it can prevent the stones on the surface or in the inner layer from being turned back into the inner layer of the soil, resulting in damage to the soil structure. On the other hand, the stones covering the soil surface can increase the roughness of the soil surface, improve the resistance of the soil to wind and water flow, thereby reducing soil erosion and maintaining the fertility and structural stability of the soil.

[0045] Working principle: First, push the equipment to move to the position where soil needs to be turned, and drive the soil-breaking cylinder 4 to rotate through the driving motor 3. Then, drive multiple excavation buckets 5 to excavate the soil through the rotating soil-breaking cylinder 4. After the excavation bucket 5 excavates the soil, it can fall into the soil-breaking chamber 602 from the collection chamber 604 during the subsequent circumferential movement of the excavation bucket 5.

[0046] Next, during the rotation of the soil-breaking cylinder 4, it can synchronously drive three shaft rods 606 to move circumferentially around the shaft column 601. At this time, the limiting column 609 is used to limit the large gear 608, so that during the meshing of the three small gears 607 and the large gear 608, since the large gear 608 cannot rotate, the three small gears 607 moving circumferentially around the large gear 608 can rotate, and then the three shaft rods 606 during the circumferential movement can rotate. Thus, a number of pulverizing pieces 610 in the soil-breaking chamber 602 can be driven by the three shaft rods 606 to break the caked soil falling into the soil-breaking cylinder 4, ensuring the degree of fragmentation and looseness of the soil.

[0047] Next, use the rotating soil-breaking cylinder 4 to roll and screen the pulverized soil, so that during the rotation of the soil-breaking cylinder 4, the soil particles are evenly distributed in the cylinder, and the soil particles are subjected to centrifugal force in the soil-breaking cylinder 4, which helps the particles pass through the sieve holes 611 faster and improves the screening efficiency.

[0048] Next, a sieve plate 612 is fixedly connected to the inner wall of the collection chamber 604 corresponding to the stone removal component 7, so that the excavated soil can be screened, the stones in the soil can be blocked and retained, and the pulverizing pieces 610 can be prevented from being damaged by falling into the soil-breaking cylinder 4.

[0049] Next, when the digging bucket 5 is vertically upward, only the blocked stones are gathered in the collection cavity 604. At the same time, when the digging bucket 5 moves to the vertically upward position, it will synchronously drive the driven gear 702 to contact and mesh with the rotating driving gear 705, causing the rotating rod 701 to rotate. During the rotation of the rotating rod 701, the cooperation between the spiral groove 709 and the sliding bead 710, and the rotation restriction of the cross bar 707 by the collection cavity 604 can be utilized. When the cross bar 707 cannot rotate, it can drive the two cross bars 707 to move closer to each other synchronously. Thus, the two cross bars 707 moving quickly closer to each other can drive several staggered inclined bars 711 arranged on both sides to move, and the inclined surface can be used to guide the stones to move out of the collection cavity 604. Therefore, under the rapid approach of the two cross bars 707, the detained stones are ejected from the collection cavity 604 and fall on the soil surface.
