Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a combined plowshare plow with a bar-type plow wall capable of self-excited swing in a land leveling and tilling machine. Background Art

[0002] The moldboard plow with an integral moldboard structure is a traditional leveling and tilling assembly. It has been used for many years in agricultural mechanized tillage and tillage operations because of its good bulldozing and turning performance. However, when the integral moldboard is used in humid areas or sticky soil, the integral moldboard is very likely to adhere the wet or sticky soil to the front wall of the integral moldboard, making it difficult to remove the soil and having poor soil crushing ability. This not only affects and reduces the quality of leveling and tillage operations, but also greatly increases the traction power consumption due to increased resistance, thereby increasing the operating cost. In recent years, with the development and improvement of scientific and technological levels, a bar-type moldboard plow with an easy-to-remove soil, low operating resistance, and low traction power consumption has been successfully developed and widely used in production operations. However, in practical operation, it is found that since the existing bar-type moldboards are fixedly installed on the plow body assembly in a fixed manner, technical problems such as poor soil crushing ability and low soil crushing quality still occur during tillage operations, and the leveling and tillage operation effect needs to be improved and improved. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of leveling and land leveling operations, and develop and design a combined plowshare plow with a bar-type plow wall that can self-oscillate, so as to greatly improve the soil crushing ability of leveling and land leveling operations, ensure the quality and effect of soil crushing operations, reduce the number of subsequent leveling and harrowing operations, and reduce the cost of land leveling operations.

[0004] The purpose of the invention is achieved in the following way: an integral plowboard is fixed on the front side of the plow side plate, a plowshare is fixedly mounted on the bottom end of the integral plowboard, a plurality of bar-type plowboards are sequentially mounted on the rear side of the integral plowboard from top to bottom through hinges so as to be able to swing back and forth in the front and rear directions, front rod seats are symmetrically fixed on the rear side surface of the end of each bar-type plowboard, a front connecting rod is swingably hingedly mounted on the front rod seat through a pin A; a bar-type beam is fixedly mounted on the rear side of the plow side plate at the rear of the plurality of bar-type plowboards through two support rods, a number of spring seats equal to the number of the plurality of bar-type plowboards are sequentially fixed on the bar-type beam, a pin C is connected to the spring seat. A sleeve is hingedly mounted in a swingable manner, a spring rod is axially movably inserted into the sleeve, a pressure spring is sleeved on the outside of the spring rod, an upper end face of the pressure spring is in compression contact with the sleeve, and a lower end face of the pressure spring is axially positioned on the spring rod. Rear connecting rods, the same number as the number of spring seats, are hingedly mounted in sequence on the rod-type beam through a rear rod seat and a pin B so as to be swingable up and down, the front side of the rear connecting rod is hung and hingedly connected to the lower end of the spring rod, the front end of the rear connecting rod is relatively rotatably hinged to the rear end of the front connecting rod, and the front connecting rod and the rear connecting rod are configured as a whole in an upwardly convex shape, thereby constituting a combined plow with a bar-type plow wall that can self-excite and swing.

[0005] The invention adopts a self-excited structure to realize and complete the reciprocating swinging motion of multiple bar-type plow walls during operation, and effectively performs vibration-type slapping and striking on the turned-up soil, which greatly improves the quality and effect of soil crushing operations during leveling and tilling, and fundamentally changes the traditional bar-type plow wall fixed structure. It has the characteristics of novel, unique, and reasonable structure, strong soil crushing ability, good operation quality, high efficiency, reliable use, and significant energy-saving effect, and provides technical support for reducing the number of leveling, crushing and harrowing operations and reducing operation costs in the subsequent process.

[0013] The following is a detailed description of the implementation scheme of the invention with reference to the accompanying drawings. A combined moldboard plow with a bar-type plowboard that can self-excite and swing, comprising a plow frame assembly 1, a three-point suspension assembly 10 fixedly mounted on the front end of the plow frame assembly 1, a depth-limiting wheel 19 that can be adjusted up and down on the lower rear end of the plow frame assembly 1, a plow post 2 fixedly mounted vertically on the lower side of the plow frame assembly 1, a plow side plate 4 fixedly mounted on the lower side of the plow post 2 through a plow support 3, an integral plowboard 5 fixedly mounted on the front side of the plow side plate 4, and a plowshare 6 fixedly mounted on the plow frame assembly 1. It is mounted on the bottom end of the integral plowboard 5, and a plurality of bar-type plowboards 8 are sequentially mounted on the rear side of the integral plowboard 5 from top to bottom through hinges 7 so as to be reciprocatingly swingable in the front and rear directions. A front rod seat 16 is symmetrically fixed on the rear side of the end of each bar-type plowboard 8, and a front connecting rod 15 is swingably hingedly mounted on the front rod seat 16 through a pin A23; on the rear side of the plow side plate 4, at the rear of the plurality of bar-type plowboards 8, two connecting rods are mounted. The support rod 18 supports the fixed rod-type beam 9, and spring seats 11 of the same number as the plurality of bar-type plow walls 8 are fixedly installed on the rod-type beam 9 in sequence. A sleeve 12 is swingably hinged on the spring seat 11 through a pin C17, and a spring rod 14 is axially movably inserted into the sleeve 12. A pressure spring 13 is sleeved on the outside of the spring rod 14, and the upper end surface of the pressure spring 13 is in extrusion contact with the sleeve 12, and the lower end surface of the pressure spring 13 is axially positioned on the spring rod 14. Rear connecting rods 20 of the same number as the spring seats 11 are hingedly installed in sequence on the rod-type beam 9 through a rear rod seat 21 and a pin B22 so as to be swingable up and down. The front side of the rear connecting rod 20 is connected to the lower end of the spring rod 14 in a hanging hinge connection, and the front end of the rear connecting rod 20 is hinged to the rear end of the front connecting rod 15 so as to be relatively rotatable, and the front connecting rod 15 and the rear connecting rod 20 are configured as an upward convex shape as a whole.

[0014] When in use, the three-point suspension assembly 10 is used to connect the entire plow to the hydraulic suspension system at the rear of the tractor, and the plow is pulled forward. Under the support and control of the depth-limiting wheel 19, the plowshare 6 and the integral plow wall 5 penetrate into the soil, and the cut soil furrow is transported to the front side of the multiple bar-type plow walls 8 located at the upper rear. Under the action of the unstable and changing resistance of the soil furrow, the bar-type plow wall 8 is controlled by the hinge 7 to swing backward on the integral plow wall 5, and the front connecting rod 15 and the rear connecting rod 20 are integrally protruded upward, driving the spring rod 14 to move upward on the sleeve 12, and the pressure spring 13 is compressed, and the pressure increases. Under the reaction of the increased spring pressure, the entire mechanism moves in the opposite direction, driving the bar-type plow wall 8 to swing forward on the integral plow wall 5, and the continuous cycle action is repeated in sequence to complete the operation of beating, knocking and breaking the soil furrow.
