Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic machinery, and in particular relates to a large hydraulic reversible plough. Background Art

[0002] The hydraulic flip plow consists of a traction frame, a plowshare, auxiliary wheels and a hydraulic cylinder. When in use, the entire flip plow is fixed to the agricultural equipment through the traction frame, and the plowshare is inserted into the soil. As the agricultural equipment moves forward with the traction frame, the plowshare leaves a plough surface in the soil after turning over the soil. Moreover, under the control of the hydraulic cylinder turning, the type of plowshare can also be replaced, and the turned soil can be leveled or processed again under the traction of the agricultural equipment.

[0003] When the hydraulic tipping plow is pulled forward, the auxiliary wheel arranged on the opposite side thereof moves forward synchronously. The auxiliary wheel is located on the opposite side of the plowshare, and the plowshare plays a role of auxiliary balance when the plowshare turns the soil forward. However, the soil after the plowshare turns the soil will adhere to the auxiliary wheel, causing the wheel diameter of the auxiliary wheel to become larger. The auxiliary wheel will cause the plowshare to be unbalanced when assisting in moving forward. The existing cleaning method is manual cleaning, which has high labor intensity and low efficiency.

[0014] The beneficial effects of the present invention are:

[0015] 1. Two sets of upper and lower auxiliary wheel assemblies are installed on the traction frame. When the lower auxiliary wheel and the lower plowshare are turned downward, the lower plowshare is inserted into the soil to turn the soil, and the lower auxiliary wheel falls on the soil on the opposite side of the lower plowshare to support the plow frame. When the lower plowshare moves forward to turn the soil, the lower auxiliary wheel keeps the plow frame balanced and assists the plow frame to move forward smoothly. The lower auxiliary wheel will also rotate as it moves along the soil. The shaft where the lower auxiliary wheel is located drives the driven sprocket to rotate, the driven sprocket and the chain drive the driving sprocket to rotate, and the shaft where the driving sprocket is located drives the eccentric wheel to rotate. When the raised part on the eccentric wheel rotates to contact with the lower driving wheel, it will push the lower driving wheel to rise, and the lower driving wheel will push the lower driving rod to rise, and the lower driving rod will push the upper shovel plate to rise. When the upper shovel plate rises, it moves relative to the outer cylindrical surface of the upper auxiliary wheel, so that when the upper auxiliary wheel is used as an auxiliary, the attached clay will automatically fall off, replacing manual labor.

[0016] When the plow frame flips 360 degrees again, the upper auxiliary wheel and the upper plowshare flip downward, the upper plowshare is inserted into the soil to turn the soil, and the upper auxiliary wheel falls on the soil on the opposite side of the upper plowshare to support the plow frame and assist the plow frame to move forward smoothly. When the upper auxiliary wheel moves along the soil, it will also rotate, and the shaft where the upper auxiliary wheel is located will drive the driven sprocket to rotate, the driven sprocket and the chain will drive the driving sprocket to rotate, and the shaft where the driving sprocket is located will drive the eccentric wheel to rotate. When the raised part on the eccentric wheel rotates to contact the upper drive wheel, it will push the upper drive wheel to rise, and the upper drive wheel will push the upper drive rod to rise, and the upper drive rod will push the lower shovel plate to rise. When the lower shovel plate rises, it moves relative to the outer cylindrical surface of the lower auxiliary wheel, so that when the lower auxiliary wheel is used as an auxiliary wheel along the soil, the clay attached to it will automatically fall off, replacing manual labor and improving work efficiency.

[0017] 2. At least three friction rollers are installed in a circular array in the weight-reducing cavity of the upper auxiliary wheel. These three friction rollers are equivalent to setting three loads at three positions of the upper auxiliary wheel. After the upper shovel plate cleans the clay at a certain outer circumference position of the upper auxiliary wheel, the upper auxiliary wheel will experience eccentric weightlessness and self-rotation, so that the clay attached to other positions on the outer circumference of the upper auxiliary wheel rotates to the shoveling position of the upper shovel plate. As the upper shovel plate rises again, the clay on the upper auxiliary wheel is completely removed. Similarly, after the lower shovel plate cleans the clay at a certain outer circumference position of the lower auxiliary wheel, the lower auxiliary wheel will experience eccentric weightlessness and self-rotation, so that the clay attached to other positions on the outer circumference of the lower auxiliary wheel rotates to the shoveling position of the lower shovel plate. As the lower shovel plate rises again, the clay on the lower auxiliary wheel is completely removed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] The present invention provides a large hydraulic reversible plow, such as Figures 1 to 6As shown, it includes a traction frame 1, a plow frame 2 is connected to the rear end of the traction frame 1, a hydraulic cylinder 3 is connected between the traction frame 1 and the plow frame 2, an upper plowshare 4 is fixed on the top of the plow frame 2, a lower plowshare 5 is fixed on the bottom of the plow frame 2, an upper auxiliary wheel assembly 6 symmetrically on the opposite side of the upper plowshare 4 is fixed on the top of the plow frame 2, a lower auxiliary wheel assembly 7 symmetrically on the opposite side of the lower plowshare 5 is fixed on the top of the plow frame 2, the upper auxiliary wheel assembly 6 includes an upper welded pipe 61 welded to the plow frame 2, and also includes an upper auxiliary wheel 62 fixed to the top of the upper welded pipe 61, the lower auxiliary wheel assembly 7 includes a lower welded pipe 71 welded to the plow frame 2, and also includes a lower auxiliary wheel 72 fixed to the lower bottom end of the lower welded pipe 71, and the auxiliary wheel assembly 6 also includes A guide seat 8 is installed on the upper welding pipe 61 and the lower welding pipe 71, an upper driving rod 63 is installed on the guide seat 8 on the upper welding pipe 61, a lower shovel plate 64 is welded to the bottom end of the upper driving rod 63, and the lower shovel plate 64 is close to the lower auxiliary wheel 72, a lower driving rod 73 is installed on the guide seat 8 on the lower welding pipe 71, an upper shovel plate 74 is welded to the top end of the lower driving rod 73, and the upper shovel plate 74 is close to the upper auxiliary wheel 62, a sprocket assembly 9 is installed on the upper welding pipe 61 and the lower welding pipe 71, the sprocket assembly 9 on the upper welding pipe 61 is transmission-connected between the top end of the upper driving rod 63 and the upper auxiliary wheel 62, and the sprocket assembly 9 on the lower welding pipe 71 is transmission-connected between the bottom end of the driving rod 73 and the lower auxiliary wheel 72.

[0027] The sprocket assembly 9 includes a transmission shaft 91 installed on the upper welding tube 61 and the lower welding tube 71, a driving sprocket 92 installed on the two transmission shafts 91, a driven sprocket 93 installed on the rotating shaft where the upper auxiliary wheel 62 and the lower auxiliary wheel 72 are located, and a chain 94 transmission-connected between the driving sprocket 92 and the upper auxiliary wheel 62, an eccentric wheel 95 is installed on the two transmission shafts 91, an upper driving wheel 65 capable of contacting the eccentric wheel 95 is installed at the top end of the upper driving rod 63, and a lower driving wheel 75 capable of contacting the eccentric wheel 95 is installed at the bottom end of the lower driving rod 73.

[0028] The side of the lower shovel plate 64 facing the lower auxiliary wheel 72 is provided with a first inclined surface 641 inclined in the tangent direction of the outer circumference of the lower auxiliary wheel 72 , and the side of the upper shovel plate 74 facing the upper auxiliary wheel 62 is provided with a second inclined surface 741 inclined in the tangent direction of the outer circumference of the upper auxiliary wheel 62 .

[0029] Working principle and effect: The entire reversible plow is installed on the agricultural equipment through the traction frame 1, and the agricultural equipment pulls the entire reversible plow to complete the soil turning operation. When the hydraulic cylinder 3 is actuated, the plow frame 2 is driven, and the plow frame 2 drives all the above components to complete a 360-degree rotation to meet the needs of covering the soil after turning the soil (the existing technology of the hydraulic reversible plow, briefly described). Different from the existing technology: when the traction frame 1 moves forward and under the action of the hydraulic cylinder 3, the plow frame 2 turns the lower auxiliary wheel 72 and the lower plowshare 5 downward, the lower plowshare 5 is inserted into the soil to turn the soil, and the lower auxiliary wheel 72 falls on the soil on the opposite side of the lower plowshare 5 to support the plow frame 2. When the lower plowshare 5 moves forward to turn the soil, the lower auxiliary wheel 72 keeps the plow frame 2 balanced and assists the plow frame 2 to move forward smoothly. The lower auxiliary wheel 72 also rotates when it moves along the soil, and the shaft where the lower auxiliary wheel 72 is located drives the driven sprocket 93 to rotate, and the driven sprocket 93 and the chain 94 drive the driving sprocket 92 to rotate, and the driving sprocket The shaft 92 is rotated with the eccentric wheel 95. When the raised part on the eccentric wheel 95 rotates to contact with the lower driving wheel 75, it will push the lower driving wheel 75 to rise, and the lower driving wheel 75 will push the lower driving rod 73 to rise, and the lower driving rod 73 will push the upper shovel plate 74 to rise. When the upper shovel plate 74 rises, it moves relative to the outer cylindrical surface of the upper auxiliary wheel 62, so that when the upper auxiliary wheel 62 is used as an auxiliary, the attached clay will automatically fall off, replacing manual labor. At least three friction rollers 13 are installed in an annular array in the weight reduction cavity 672 of the upper auxiliary wheel 62. These three friction rollers 13 are equivalent to setting three loads at three positions of the upper auxiliary wheel 62. After the upper shovel plate 74 cleans the clay on a certain outer cylindrical position of the upper auxiliary wheel 62, the upper auxiliary wheel 62 undergoes eccentric weightlessness and rotates, so that the clay attached to other positions on the outer cylindrical surface of the upper auxiliary wheel 62 rotates to the shoveling position of the upper shovel plate 74. As the upper shovel plate 74 rises again, the clay on the upper auxiliary wheel 62 is completely removed.

[0030] Similarly, when the plow frame 2 flips 360 degrees again, the upper auxiliary wheel 62 and the upper plowshare 4 are turned downward (the entire upper auxiliary wheel assembly 6 is changed from being on the top to being on the bottom, and the entire lower auxiliary wheel assembly 7 is changed to being on the top), the upper plowshare 4 is inserted into the soil to be responsible for turning the soil, and the upper auxiliary wheel 62 falls on the soil on the opposite side of the upper plowshare 4 to be responsible for supporting the plow frame 2 and assisting the plow frame 2 to move forward smoothly. When the upper auxiliary wheel 62 moves along the soil, it will also rotate. The shaft on which the upper auxiliary wheel 62 is located drives the driven sprocket 93 to rotate. The driven sprocket 93 and the chain 94 drive the driving sprocket 92 to rotate. The shaft on which the driving sprocket 92 is located drives the eccentric wheel 95 to rotate. When the protrusion on the eccentric wheel 95 rotates to contact the upper driving wheel 65, it pushes the upper driving wheel 65 to rise. The upper driving wheel 65 pushes the upper driving rod 63 to rise. The upper driving rod 63 pushes the lower shovel plate 64 to rise. When the lower shovel plate 64 rises, it moves relative to the outer cylindrical surface of the lower auxiliary wheel 72, so that when the lower auxiliary wheel 72 is used as an auxiliary wheel along the soil, the clay attached to it automatically falls off, replacing manual labor and improving work efficiency. Similarly, after the lower shovel plate 64 cleans the clay on a certain outer circumferential position of the lower auxiliary wheel 72, the lower auxiliary wheel 72 rotates due to eccentric weightlessness, causing the clay attached to other positions on the outer circumferential surface of the lower auxiliary wheel 72 to rotate to the shoveling position of the lower shovel plate 64. As the lower shovel plate 64 rises again, the clay on the lower auxiliary wheel 72 is completely removed.

[0031] A weight-reducing cavity 672 is provided inwardly from the outer surface of the upper auxiliary wheel 62 and the lower auxiliary wheel 72, and weight-reducing holes 673 are provided from the weight-reducing cavity 672 to the inner surface of the upper auxiliary wheel 62 and the lower auxiliary wheel 72. The weight-reducing holes 673 are at least three in a circular array. When the upper auxiliary wheel 62 and the lower auxiliary wheel 72 are manufactured, the material is reduced, and the casting process can be used to complete the manufacturing process, thereby reducing the cost. In addition, the purpose of the weight-reducing cavity 672 in the upper auxiliary wheel 62 and the lower auxiliary wheel 72 is not only to reduce weight and reduce costs, but also to form a rib 674 between two adjacent weight-reducing holes 673 on the inner surface of the upper auxiliary wheel 62 and the lower auxiliary wheel 72. A rotating rod 12 is installed on the rib 674. One end of the rotating rod 12 extends into the weight-reducing cavity 672 and is installed with a friction roller 13. A tooth plate 14 is welded on the upper welding pipe 61 and the lower welding pipe 71, and an auxiliary gear 15 is installed on the other end of one of the rotating rods 12. The friction roller 13 is conical, and a friction texture is provided along the conical direction.

[0032] It can be seen that no matter it is the lower auxiliary wheel 72 or the upper auxiliary wheel 62, when they move along the soil as a support, they will also rotate with all the friction rollers 13. Among them, the friction roller 13 with the auxiliary gear 15 will also rotate the auxiliary gear 15 to the tooth plate 14. The auxiliary gear 15 rotates due to meshing with the tooth plate 14, and the auxiliary gear 15 rotates with the friction roller 13. Since the friction roller 13 is located in the weight-reducing cavity 672 of the lower auxiliary wheel 72 and the upper auxiliary wheel 62, when the lower auxiliary wheel 72 and the upper auxiliary wheel 62 rotate and move along the soil, it is inevitable that the clay adheres to the weight-reducing cavity 672. Once the friction roller 13 rotates, it will destroy the soil stickiness, causing the clay to stick to the weight-reducing cavity 672. The friction roller 13 rotates to knead the clay in the weight-reducing cavity 672 by the friction texture, making the clay loose, thereby causing the clay to fall off. The opening of the weight-reducing cavity 67 not only saves the material cost of the upper auxiliary wheel 62 and the lower auxiliary wheel 72, but also solves the problem of clay adhering to the end sides of the upper auxiliary wheel 62 and the lower auxiliary wheel 72. The setting of the friction roller 13 not only provides a weightless eccentric force when the upper auxiliary wheel 62 and the lower auxiliary wheel 72 are turned over and the clay on the outer circular surface is removed by the lower shovel plate 64 or the upper shovel plate 74, but also automatically cleans the clay adhering to their side ends when the upper auxiliary wheel 62 and the lower auxiliary wheel 72 are turned over and serve as auxiliary supports, thus having a dual effect.

[0033] like Figure 2 , Figure 4 As shown, a discharge channel 671 is opened along the inclined direction of the first inclined surface 641 and the second inclined surface 741 . When the lower shovel plate 64 or the upper shovel plate 74 is shoveling soil, the clay falls downward through the discharge channel 671 .

[0034] like Figure 6 As shown, a through hole 81 is provided on the guide seat 8, and the upper driving rod 63 and the lower driving rod 73 pass through and are assembled in the through hole 81. A baffle 10 is welded on the upper driving rod 63 and the lower driving rod 73, and a spring 11 is sleeved on the upper driving rod 63 and the lower driving rod 73. A stepped hole 82 is provided in the through hole 81, and the spring 11 is filled in the stepped hole 82. The two ends of the spring 11 are elastically connected between the baffle 10 and the bottom of the stepped hole 82. When the upper driving rod 63 or the lower driving rod 73 rises, the baffle 10 will be used to push the spring 11 to compress and shorten, and when the protrusion on the eccentric wheel 95 rotates to separate from the upper driving wheel 65 or the lower driving wheel 75, the spring 11 releases its length and uses the baffle 10 to push the upper driving rod 63 and the lower driving rod 73 to reset, so that the lower shovel plate 64 or the upper shovel plate 74 automatically completes a shoveling action against the outer cylindrical surface of the upper auxiliary wheel 62 or the lower auxiliary wheel 72.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures.
