[0002] A plow is a soil tillage machine with the main function of turning over soil and having the functions of loosening and crushing soil. There are mainly types such as moldboard plows, disk plows, rotary plows, etc. Among them, the moldboard plow is suitable for tilling dry land of cultivated land in sandy loam areas, and has the characteristics of simple structure, large tillage adaptation range, good soil crushing and covering performance, and small furrow.

[0003] At present, a large area of sandy loam dry land in the northwest region needs to be tilled by a moldboard plow. Since the surface of the moldboard plowshare is mostly a smooth curved surface, when tilling sandy loam dry land, the long-term friction of the plowshare surface by sand and gravel will cause the plowshare to be continuously heated, resulting in increased wear of the plowshare. This not only affects the service life of the plowshare, but also requires frequent shutdowns during tillage to cool the plowshare, thus affecting tillage efficiency. Summary of the Utility Model

[0004] An embodiment of the utility model provides a moldboard plowshare and a moldboard plow, aiming to improve the service life of the moldboard plowshare and improve tillage efficiency.

In the description of the present application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0025] Please also read Figures 1 to 5 The moldboard plowshare provided by the utility model is now described. The moldboard plowshare comprises a plow post, and a plowshare 10, a plow tip 20 and a plowboard 30 connected to the plow post, the plow tip 20 is connected to the side boundary of the plowshare 10, and the upper boundary of the plow tip 20 is aligned with the upper boundary of the plowshare 10, the lower end of the plow tip 20 protrudes downward from the lower boundary of the plowshare 10, the lower boundary of the plowboard 30 is connected to the upper boundaries of the plowshare 10 and the plow tip 20, and the front boundary of the plowboard 30 is aligned with the front boundary of the plow tip 20; wherein, the front surfaces of the plowshare 10, the plow tip 20 and the plowboard 30 respectively form soil facing surfaces 100, and each soil facing surface 100 has a diversion protrusion array 200, and the diversion protrusion array 200 is used to guide the sandy soil to separate from the soil facing surface 100 to form a heat dissipation air gap.

[0026] It should be noted that in this embodiment, the connection methods of the plowshare 10, the plow tip 20 and the plow wall plate 30 to the plow column can be the connection methods of the prior art, that is, they are fixedly connected to the plow column through the plow bracket and the connecting bolts. The alignment among the plow tip 20, the plowshare 10 and the side plow plate aims to form an integral curved surface structure to guide and turn the sandy loam to the side of the furrow. Concave-convex stop grooves or stepped surface laps can be provided among the three to improve the docking stability, but no connecting pieces are required to ensure the smoothness of the soil-facing surface 100.

[0027] In this embodiment, the diversion protrusion array 200 can be a protrusion array processed on the soil-facing surface 100 by using the surfacing process, or can be integrally formed on the soil-facing surface 100 directly by using the 3D printing method. At the same time, in order to avoid affecting the smooth flow of the sandy loam along the soil-facing surface 100, each protrusion of the diversion protrusion array 200 is set to a structure extending along the sandy loam flow direction.

[0028] The moldboard plowshare provided in this embodiment is mainly aimed at tilling sandy loam dry fields. Considering the large amount of heat generated by the frictional contact between the loose sandy loam and the soil-facing surface 100, the diversion protrusion array 200 provided on the soil-facing surface 100 can make the sandy loam fluctuate during the flowing process, so as to form a heat dissipation air gap between the sandy loam and the soil-facing surface 100. Due to the forward movement during the tilling process, the air and the soil-facing surface 100 are in relative motion, so that the air continuously enters the heat dissipation air gap to take away the frictional heat, thereby realizing the air cooling of the soil-facing surface 100 and alleviating the high temperature of the soil-facing surface 100.

[0029] Compared with the prior art, for the moldboard plowshare provided in this embodiment, the plowshare 10, the plow tip 20 and the plow wall plate 30 are all fixedly connected to the plow column, and the three are connected to each other so that their respective soil-facing surfaces 100 form a complete and flush wall surface to ensure the smoothness of soil turning; by providing the diversion protrusion array 200 on each soil-facing surface 100, the guiding effect of the diversion protrusion array 200 on the sandy loam can be utilized to make the sandy loam form fluctuations on the soil-facing surface 100, so that the sandy loam is intermittently separated from the soil-facing surface 100 to form a heat dissipation air gap. Along with the tilling process, the air continuously enters the heat dissipation air gap to cool the soil-facing surface 100, avoiding the excessive temperature of the soil-facing surface 100 during continuous tilling and aggravating the wear. It can not only improve the service life, but also extend the continuous tilling time, thereby improving the tilling efficiency.

[0030] In some embodiments, refer to Figure 2, the diversion convex rib array 200 includes a number of convex ribs 201 distributed in an array, and the convex ribs 201 are used to extend along the flowing direction of sandy loam. The sandy loam is separated from the soil-facing surface 100 under the guidance of the convex ribs 201 to generate a heat dissipation air gap. At the same time, in order to prevent the separation gap between the sandy loam and the soil-facing surface 100 from being too large and affecting its final flow direction, the convex ribs 201 are set as a small-segment structure distributed in an array here, and by arranging each segment of the convex ribs 201 to extend along the normal flowing direction of the sandy loam, it is avoided that the convex ribs 201 block the normal flow direction of the sandy loam, so that the sandy loam continuously undulates on the soil-facing surface 100 to form a wavy flow state, thereby realizing the heat dissipation effect on the soil-facing surface 100 during the tillage process.

[0031] As a variant implementation manner of the above convex rib 201, please refer to Figure 4 , the height of the convex rib 201 protruding from the soil-facing surface 100 gradually increases along the flowing direction of the sandy loam ( Figure 4 the direction indicated by the arrow). The lower end of the convex rib 201 is smoothly transitioned with the soil-facing surface 100 and gradually rises from bottom to top along the flowing direction of the sandy loam. Thus, it can enable the sandy loam to be gradually separated from the soil-facing surface 100 as the height of the convex rib 201 increases during the flowing process, and it can avoid the convex rib 201 generating a stepped blocking collision on the sandy loam and affecting the flow stability of the sandy loam.

[0032] As another variant implementation manner of the above feature A, please refer to Figure 3 and Figure 5 , the width of the convex rib 201 gradually increases along the flowing direction of the sandy loam ( Figure 5 the direction indicated by the arrow). Specifically, the cross-section of the convex rib 201 is semi-circular or semi-elliptical. Thus, the convex rib 201 can be a water-drop-shaped structure with the small end protruding from the soil-facing surface 100 downward. Thus, it can form a heat dissipation air gap between the sandy loam and the soil-facing surface 100 on the premise of ensuring the smooth flow of the sandy loam, and at the same time, it is also beneficial to reduce the frictional heat generation between the convex rib 201 and the sandy loam.

[0033] Optionally, in this embodiment, the above convex rib 201 is a surfacing wear-resistant weld seam. Due to the guiding effect of the convex rib 201 on the sandy loam, its friction with the sandy loam is more obvious than that between the soil-facing surface 100 and the sandy loam. Therefore, a wear-resistant electrode is selected here to form a protruding weld seam on the soil-facing surface 100 by surfacing as the convex rib 201, which can improve the wear resistance of the convex rib 201 and thus improve the service life.

[0034] It should be noted that as Figure 1As shown, a bottom edge 11 is provided at the lower boundary of the plowshare 10, and a soil-breaking tip edge 21 and a side edge 22 connected to the soil-breaking tip edge 21 are provided at the lower end of the plow point 20. The side edge 22 is connected to the bottom edge 11 and is arranged at an angle. Using the soil-breaking tip edge 21 and the side edge 22 to break the soil can reduce the soil penetration resistance of the plow point 20. At the same time, the connection of the side edge 22 and the bottom edge 11 enables the plowshare 10 to break the soil smoothly after the plow point 20 breaks the soil, reducing the soil-breaking resistance of the plowshare 10.

[0035] The bottom edge 11, as the soil-breaking part of the plowshare 10, has the most serious friction with the sandy soil. The soil-breaking tip edge 21 and the side edge 22, as the soil-breaking parts of the plow point 20, have the most serious friction with the sandy soil. Therefore, in order to improve the service life, wear-resistant layers are provided on the surfaces of the above-mentioned bottom edge 11, soil-breaking tip edge 21 and side edge 22. This wear-resistant layer can specifically be a wear-resistant solder layer formed by surfacing with a wear-resistant electrode, or a wear-resistant material layer generated by electroplating.

[0036] In some embodiments, as Figure 2 shown, a first lapping platform 12 is provided at the side boundary of the plowshare 10, and a second lapping platform 23 is provided at the side boundary of the plow point 20. The second lapping platform 23 and the first lapping platform 12 are overlapped with each other, and the soil-facing surfaces 100 of the plow point 20 and the plowshare 10 are flush. The first lapping platform 12 and the second lapping platform 23 adopt a buckled L-shaped structure. By overlapping the first lapping platform 12 and the second lapping platform 23 with each other, the docking stability between the plowshare 10 and the plow point 20 can be improved, and at the same time, the soil-facing surfaces 100 of the two can be ensured to be flush, thus ensuring the smoothness of the sandy soil turning.

[0037] Based on the same inventive concept, in combination with Figures 1 to 5 understanding, the embodiment of the present application also provides a moldboard plow, including the above-mentioned moldboard plow head.

[0038] Compared with the prior art, the moldboard plow provided in this embodiment adopts the above-mentioned moldboard plow head. By arranging a diversion convex array 200 on each soil-facing surface 100, the guiding effect of the diversion convex array 200 on the sandy soil can be utilized to make the sandy soil form fluctuations on the soil-facing surface 100, so that the sandy soil is intermittently separated from the soil-facing surface 100 to form a heat dissipation air gap. Along with the tillage process, air continuously enters the heat dissipation air gap to cool the soil-facing surface 100, avoiding the excessive temperature of the soil-facing surface 100 during continuous tillage and aggravating wear. It can not only improve the service life, but also extend the continuous tillage time, thereby improving the tillage efficiency.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
