Description

Technical Field

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

[0002] Soil tillage is a soil cultivation method that uses a plow or other farm implements to shovel up, loosen and turn over the soil. It is commonly known as ploughing, plowing or plowing. It has a long history of application in world agriculture and is widely used. China began to use a plow with a plow wall to till the land more than 2,000 years ago. Tillage refers to shoveling up, breaking up, dredging, etc. to make the land flat and loose. It is the most basic process of farming for farmers. Tillage allows seeds to breathe and grow easily in the soil. Tillage has been used for thousands of years in northern and southern China. It is also the only unified farming method in the north and south. At present, agricultural planting tillage has basically been mechanized.

[0003] At present, although agricultural tillers can also crush the 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, it is often necessary to plow many times 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 tilling the soil, tilling equipment often encounters stones on the soil surface. When the blades or plowshares of the tilling equipment cut into the soil, these stones are easily rolled into them and buried in the soil as the tilling action goes deeper, so that the stones occupy the effective space in the soil, reducing the porosity of the soil, thereby affecting the air permeability and water retention capacity of the soil, which is not conducive to agricultural planting.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figure 1-7 The present invention provides soil turning equipment for agricultural planting, including a mobile body 1, a mounting groove 2 is opened through the top of the mobile body 1, and a driving motor 3 is fixedly installed on the outer wall of one side of the mobile body 1, a soil crushing cylinder 4 is arranged inside the mounting groove 2, and an excavating bucket 5 is fixedly connected to the outer wall of the soil crushing cylinder 4 at equal distances.

[0020] The soil crushing cylinder 4 is provided with an excavating and crushing soil component 6 therein.

[0021] Furthermore, the excavating and crushing component 6 includes two shaft columns 601, and the ends of the two shaft columns 601 that are close to each other are fixedly connected to the centers of the two end surfaces of the soil crushing cylinder 4. One end of the shaft column 601 that is away from the soil crushing cylinder 4 is rotatably connected to the inner wall of the mounting groove 2, and the end of the other shaft column 601 that is away from the soil crushing cylinder 4 is fixedly connected to the output shaft of one end of the driving motor 3. A soil crushing cavity 602 is provided inside the soil crushing cylinder 4, and a connecting groove 603 is provided on the outer wall of the soil crushing cylinder 4 at an equal distance corresponding to the excavating bucket 5, and a connecting groove 603 is provided on the inner wall of the excavating bucket 5. A collecting chamber 604 is provided, and the inner wall of the collecting chamber 604 is connected to the soil crushing chamber 602 through a connecting groove 603. Connecting grooves 605 are equidistantly penetrated on both end faces of the soil crushing cylinder 4, and there are three connecting grooves 605 on both end faces of the soil crushing cylinder 4. The inner walls of the three connecting grooves 605 are rotatably connected with shafts 606. The outer walls of the two ends of the three shafts 606 are fixedly connected with small gears 607. The outer walls of the two shaft columns 601 are rotatably connected with large gears 608 corresponding to the small gears 607. The large gear 608 is meshingly connected with the small gear 607.

[0022] More specifically, when turning the soil, first push the device to move to the position where turning the soil is required, then the ends of the two shaft columns 601 close to each other are fixedly connected to the centers of the two end surfaces of the soil crushing cylinder 4, and one end of the shaft column 601 away from the soil crushing cylinder 4 is rotatably connected to the inner wall of the mounting groove 2, and the end of the other shaft column 601 away from the soil crushing cylinder 4 is fixedly connected to the output shaft of one end of the driving motor 3, so that the soil crushing cylinder 4 can be driven to rotate by the driving motor 3, and then the outer wall of the soil crushing cylinder 4 is fixedly connected at an equal distance. There is an excavating bucket 5, and a soil crushing cavity 602 is opened inside the soil crushing cylinder 4, and a connecting groove 603 is opened at an equal distance through the outer wall of the soil crushing cylinder 4 corresponding to the excavating bucket 5, and at the same time, a collecting cavity 604 is opened on the inner wall of the excavating bucket 5, and the inner wall of the collecting cavity 604 is connected with the soil crushing cavity 602 through the connecting groove 603, so that multiple excavating buckets 5 can be driven by the rotating soil crushing cylinder 4 to excavate the soil, and after the excavating bucket 5 excavates the soil, it can fall from the collecting cavity 604 into the soil crushing cavity 602 during the subsequent circular movement of the excavating bucket 5.

[0023] Then, connecting grooves 605 are equidistantly penetrated through the two end surfaces of the soil crushing cylinder 4, and the number of connecting grooves 605 on the two end surfaces of the soil crushing cylinder 4 is three, and the inner walls of the three connecting grooves 605 are rotatably connected with shafts 606, and the outer walls of the two ends of the three shafts 606 are fixedly connected with small gears 607, and at the same time, the outer walls of the two shaft columns 601 are rotatably connected with large gears 608 corresponding to the small gears 607, and the large gears 608 are meshed with the small gears 607, and the end surface of the large gear 608 away from the large gear 608 is fixedly connected with a limiting column 609, and at the same time, the outer walls of the two shaft columns 601 are rotatably connected with the small gears 607. The other end of the limiting column 609 is fixedly connected to the inner wall of the mounting groove 2, so that the three shafts 606 can be synchronously driven to move in a circle around the shaft column 601 during the rotation of the soil crushing cylinder 4. At this time, the limiting column 609 is used to limit the large gear 608, so that during the meshing process of the three small gears 607 and the large gear 608, the large gear 608 cannot rotate, so that the three small gears 607 moving in a circle around the large gear 608 can rotate, thereby allowing the shaft 606 to rotate during the three circular movements.

[0024] Then, crushing pieces 610 are fixedly connected to the soil crushing cavity 602 at equal distances through the outer wall of the shaft rod 606, so that the three shaft rods 606 can drive several crushing pieces 610 in the soil crushing cavity 602 to crush the agglomerated soil that falls into the soil crushing cylinder 4, thereby ensuring the crushing 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.

[0025] Then, sieve holes 611 are opened at equal distances through the outer wall of the soil crushing cylinder 4 corresponding to the soil crushing cavity 602, so that the crushed soil can be rolled and screened by the rotating soil crushing cylinder 4, so that during the rotation of the soil crushing cylinder 4, the soil particles are evenly distributed in the cylinder, and the soil particles in the soil crushing cylinder 4 are affected by centrifugal force, which helps the particles to pass through the sieve holes 611 faster and improves the screening efficiency.

[0026] As described above, when turning the soil, the driving motor 3 can drive the three excavating buckets 5 to connect, dig and collect the soil. At the same time, the large gear 608 and the small gear 607 cooperate to make the several crushing pieces 610 in the soil crushing cylinder 4 crush the collected soil, so that the agglomerated soil can be quickly crushed. At the same time, the rotating soil crushing cylinder 4 cooperates with the sieve hole 611 to screen the crushed soil, thereby ensuring the degree of soil crushing and looseness, improving the fineness and uniformity of the soil, and laying a good foundation for subsequent agricultural operations such as sowing and fertilizing.

[0027] Embodiment 2: Based on the above embodiment, a stone removing component 7 is provided inside the excavating bucket 5 .

[0028] Furthermore, the stone removal component 7 includes a rotating rod 701, and the outer walls on both sides of the excavation bucket 5 are provided with openings for the rotating rod 701 to pass through, the inner wall of the opening is rotatably connected to the outer wall of the rotating rod 701 through a bearing, both ends of the rotating rod 701 are fixedly connected with a driven gear 702, the top of the mobile body 1 is symmetrically fixedly connected with a support plate 706, the side wall where the two support plates 706 are close to each other is rotatably connected with a rotating column 704, the end portion of the two rotating columns 704 close to each other is fixedly connected with a driving gear 705 corresponding to the driven gear 702, and the driving gear 705 is meshed and matched with the driven gear 702, the outer wall of the shaft column 601 and the rotating column 704 is provided with a pulley transmission mechanism 703, the shaft column 601 and the rotating column 704 are connected through the pulley transmission mechanism 703, the outer wall of the rotating rod 701 is symmetrically provided with a cross bar 707, and the two ends of the two cross bars 707 are both fitted and slid with the inner wall of the collecting chamber 604.

[0029] More specifically, a sieve plate 612 is fixedly connected to the stone removal component 7 through the inner wall of the collecting chamber 604, so that the excavated soil can be screened, and the stones in the soil can be blocked and retained to prevent them from falling into the soil crushing tube 4 and causing damage to the crushing pieces 610. Then, when a certain excavation bucket 5 is vertically downward, it means that the excavation has reached the deepest point of the soil. When the excavation bucket 5 continues to rotate ninety degrees, the excavation bucket 5 is horizontal, which means that the excavation is completed and the soil is gathered in the collecting chamber 604 of the excavation bucket 5. At this time, the excavation bucket 5 continues to rotate ninety degrees, that is, due to the process of changing from horizontal to vertical, the soil in the collecting chamber 604 will continue to fall into the soil crushing tube 4 under the action of gravity for the crushing step.

[0030] When the excavator bucket 5 is vertically upward, only the blocked stones are gathered in the collecting chamber 604. At this time, the two ends of the rotating rod 701 pass through the interior of the excavator bucket 5 and extend to the outside of the excavator bucket 5, and the two extended ends of the rotating rod 701 are fixedly connected with the driven gear 702. At the same time, the shaft column 601 and the rotating column 704 are connected by a pulley transmission mechanism 703. The driven gear 702 is fixedly connected with a driving gear 705 corresponding to the driven gear 702 at one end of the two rotating columns 704 that is close to each other, and the driving gear 705 is meshed and matched with the driven gear 702. Therefore, when the excavator bucket 5 moves vertically upward, it will synchronously drive the driven gear 702 to contact and mesh with the rotating driving gear 705, so that the rotating rod 701 rotates.

[0031] Then, cross bars 707 are symmetrically arranged on the outer wall of the rotating rod 701, and the two ends of the two cross bars 707 are fitted and slid with the inner wall of the collecting chamber 604, and a sliding groove 708 is opened inside the two cross bars 707. At the same time, the inner wall of the sliding groove 708 is fitted and slid with the outer wall of the rotating rod 701, and the outer wall of the rotating rod 701 is symmetrically opened with a spiral groove 709, and the spiral directions of the spiral groove 709 are set in opposite directions. At the same time, the inner wall of the sliding groove 708 is fixedly connected with a sliding ball 710 corresponding to the spiral groove 709, and the outer wall of the sliding ball 710 is fitted and slid with the inner wall of the spiral groove 709. Therefore, during the rotation of the rotating rod 701, the cooperation between the spiral groove 709 and the sliding ball 710 and the rotation restriction of the collecting chamber 604 on the cross bar 707 can be utilized, so that when the cross bar 707 cannot rotate, the two cross bars 707 can be driven to move synchronously close to each other.

[0032] Then, a plurality of staggered inclined rods 711 are fixedly connected at equal distances through the side walls of the two cross bars 707, and the ends of the plurality of staggered inclined rods 711 away from the cross bars 707 are slidably connected to the inner wall of the collecting chamber 604, so that the two cross bars 707 that quickly approach each other can be used to drive the plurality of staggered inclined rods 711 on both sides to move, and the inclined surface can be used to guide the stones outward from the collecting chamber 604, so that under the rapid approach of the two cross bars 707, the retained stones are ejected from the collecting chamber 604 and fall on the soil surface. On the one hand, it can prevent the surface or inner layer stones 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 be used to increase the roughness of the soil surface, thereby improving the soil's resistance to wind and water flow.

[0033] Then, a return torsion spring 712 is provided through the outer walls of the two extended ends of the rotating rod 701, and one end of the return torsion spring 712 is fixedly connected to the outer wall of one side of the excavator bucket 5, and the other end of the return torsion spring 712 is fixedly connected to the outer wall of the extended end of the rotating rod 701, so that when the driven gear 702 is in contact and meshing with the driving gear 705, the rotating rotating rod 701 that is rotating at this time can elastically compress the return torsion spring 712, and when the two cross bars 707 are in contact, 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, waiting for the next time to eject the stone.

[0034] Then, a protective shell 713 is fixedly connected to the driven gear 702 via the outer walls on both sides of the excavating bucket 5, so that the protective shell 713 can be used to protect the driven gear 702 on the excavating bucket 5 to prevent the driven gear 702 from directly contacting the soil during the excavation process.

[0035] By doing as above, when turning the soil, the stones in the collected soil can be blocked and retained by the sieve plate 612. At the same time, through the cooperation of the driving gear 705 and the driven gear 702, when the excavator bucket 5 rotates to a certain angle, the two cross bars 707 can be used to drive the staggered inclined bars 711 to eject the retained stones from the collection chamber 604 and drop them on the soil surface. On the one hand, it can avoid turning the surface or inner layer stones back into the inner layer of the soil, causing damage to the soil structure. On the other hand, the stones covering the soil surface can be used to increase the roughness of the soil surface and improve the soil's resistance to wind and water flow, thereby reducing soil erosion and maintaining the fertility and structural stability of the soil.

[0036] Working principle: First, the device is pushed to move to the position where the soil needs to be turned, and the soil crushing cylinder 4 is driven to rotate by the driving motor 3, and then the rotating soil crushing cylinder 4 drives multiple digging buckets 5 to dig the soil, and after the digging bucket 5 digs the soil, the soil can fall from the collection chamber 604 to the soil crushing chamber 602 during the subsequent circular movement of the digging bucket 5; Then, during the rotation of the soil crushing cylinder 4, the three shafts 606 can be synchronously driven to move in a circle around the shaft column 601. At this time, the large gear 608 is restricted by the limiting column 609, so that during the meshing process of the three small gears 607 and the large gear 608, since the large gear 608 cannot rotate, the three small gears 607 moving in a circle around the large gear 608 can rotate, and then the shafts 606 can rotate during the three circular movements, so that the three shafts 606 can drive the plurality of crushing pieces 610 in the soil crushing cavity 602 to crush the agglomerated soil that falls into the soil crushing cylinder 4, thereby ensuring the degree of soil crushing and loosening; Then, the crushed soil is rolled and screened by the rotating soil crushing cylinder 4, so that during the rotation of the soil crushing cylinder 4, the soil particles are evenly distributed in the cylinder, and the soil particles are subjected to the centrifugal force in the soil crushing cylinder 4, which helps the particles pass through the sieve holes 611 faster and improves the screening efficiency; Then, a sieve plate 612 is fixedly connected to the inner wall of the collecting chamber 604 corresponding to the stone removal component 7, so that the excavated soil can be screened and the stones in the soil are blocked and retained to prevent them from falling into the soil crushing cylinder 4 and causing damage to the crushing piece 610; Then, when the excavator bucket 5 is vertically upward, only the blocked stones are gathered in the collecting chamber 604. At the same time, when the excavator bucket 5 moves vertically upward, it will synchronously drive the driven gear 702 to contact and mesh with the rotating driving gear 705, so that the rotating rod 701 rotates. At this time, during the rotation of the rotating rod 701, the cooperation between the spiral groove 709 and the sliding ball 710 and the rotation restriction of the cross bar 707 by the collecting chamber 604 can be utilized, so that when the cross bar 707 cannot rotate, the two cross bars 707 can be driven to move synchronously towards each other, so that the two cross bars 707 that are rapidly approaching each other can be used to drive several staggered inclined bars 711 on both sides to move, and the inclined surface can be used to guide the stones outward from the collecting chamber 604, so that under the rapid approach of the two cross bars 707, the retained stones are ejected from the collecting chamber 604 and fall on the soil surface.
