Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment technology, and in particular relates to a reversible plow with adjustable connection angle. Background Technology

[0002] Reversible plows, as an important tillage device in modern agricultural machinery, achieve bidirectional tillage through the periodic rotation of the plow body, effectively improving work efficiency and maintaining a level field surface. Traditional reversible plows generally use a three-point suspension system for rigid connection with the tractor, with the connection angle fixed at the factory. This fixed connection structure has significant limitations in practical applications: when used with different tractor models, due to differences in the height of the power take-off shaft, the position of the traction point, and overall machine parameters, it is difficult for the plow body to achieve the optimal matching angle with the tractor, leading to problems such as uneven tillage depth and increased traction resistance.

[0003] To address compatibility issues, existing technologies typically employ methods such as adding adjusting shims or replacing connecting brackets to adjust the connection angle. However, these mechanical adjustment methods have significant drawbacks: firstly, they require stopping the machine to disassemble the fasteners for adjustment, severely impacting operational continuity; secondly, the adjustment accuracy is limited by the preset hole spacing, making precise control of continuous angles impossible.

[0004] Furthermore, existing adjustable connection devices generally suffer from insufficient structural redundancy. When faced with different tractor models, they cannot accommodate the varying connection heights caused by these different tractor models. This compatibility deficiency directly leads to plow body tilting, making it difficult for the reversible plow to tip over. Summary of the Invention

[0005] To address the problems of poor compatibility, low adjustment efficiency, and insufficient structural redundancy caused by the fixed connection angle between existing reversible plows and tractors, this utility model provides a reversible plow with an adjustable connection angle. The adjustment mechanism enables real-time adaptation of the traction angle, and the structural design is optimized to be compatible with different tractor models.

[0006] The technical solution adopted by this utility model is as follows: a reversible plow with adjustable connection angle, including a plow head assembly, a reversible block, a reversible block clamping plate, a support wheel assembly, a main beam, and plowshares; the reversible block is connected to the middle of the plow head assembly via a bearing, and the reversible block is driven to rotate by a reversible cylinder connected between the plow head assembly and the reversible block; the reversible block is in the shape of a "7"; the end of the reversible block is hinged to the front end of the main beam; a main beam adjusting screw is provided between the reversible block and the main beam; reversible block clamping plates are provided on the upper and lower surfaces of the reversible block; a plurality of plowshares are sequentially arranged on the main beam; the support wheel assembly is located in the middle of the main beam; and an adjusting mechanism is provided on the plow head assembly.

[0007] Furthermore, the adjustment mechanism includes a heightening plate and a heightening plate adjusting screw. One end of the heightening plate is hinged to the top of the plowshare assembly, and the other end of the heightening plate is connected to the plowshare assembly via the heightening plate adjusting screw.

[0008] Furthermore, the raised plate has several strip-shaped holes; the strip-shaped holes are two parallel slots used to expand the adjustment range of the connection point with the tractor.

[0009] The beneficial effects of this utility model are as follows: By adding an adjustment mechanism to the plow assembly, this utility model enables the reversible plow to be adapted to tractors of different models and heights, enhances the compatibility between the reversible plow and the tractor, keeps the reversible plow level during plowing, and makes it easy to flip the plow; and tilts the reversible plow during transportation, making it more convenient to transport.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, this utility model is a reversible plow with adjustable connection angle, including a plow head assembly 1, a reversible block 7, a reversible block clamping plate 8, a support wheel assembly 5, a main beam 3, and plowshares 6; the reversible block 7 is connected to the middle of the plow head assembly 1 via a bearing, and the reversible block 7 is driven to rotate by a reversible cylinder 9 connected between the plow head assembly 1 and the reversible block 7; the reversible block 7 is in the shape of a "7"; the end of the reversible block 7 is hinged to the front end of the main beam 3; a main beam adjusting screw 4 is provided between the reversible block 7 and the main beam 3; reversible block clamping plates 8 are provided on the upper and lower surfaces of the reversible block 7; several plowshares 6 are arranged sequentially along the main beam 3; the support wheel assembly 5 is located in the middle of the main beam 3 to balance the force distribution during plowing; an adjusting mechanism 2 is provided on the plow head assembly 1.

[0015] like Figure 2As shown, the adjustment mechanism 2 includes a heightening plate 201 and a heightening plate adjusting screw 202. One end of the heightening plate 201 is hinged to the top of the plow head assembly 1, and the other end of the heightening plate 201 is connected to the plow head assembly 1 via the heightening plate adjusting screw 202. The heightening plate adjusting screw 202 of the adjustment mechanism 2 adjusts the tilt angle of the heightening plate 201 by rotation to achieve dynamic adaptation between the plow head assembly 1 and the tractor. The heightening plate 201 has two slotted holes 203, which are two parallel structures. This structure design has dual functional advantages: on the one hand, during tillage operations, it can effectively expand the adjustment range of the connection point with the tractor, improving the flexibility of the equipment to adapt to different operating scenarios; on the other hand, when the reversible plow passes through potholes during tillage, it can allow the connection structure between the reversible plow and the traction equipment to slide freely within the range of the slotted holes. By constructing a redundant buffer mechanism, it avoids damage to the connection point caused by road bumps and impacts in the hard connection mode, significantly enhancing the reliability and durability of the equipment during transportation.

[0016] This utility model adjusts the height of the heightening plate 201 by adjusting the adjusting screw 202 of the heightening plate, so that it can be fixedly connected to different models of tractors through the strip hole 203 to adapt to different models and heights of tractors. It keeps the reversible plow from tilting during plowing and makes the reversible plow easy to turn over; and tilts the reversible plow during transportation to shorten the length of the reversible plow and make it easier to transport.

[0017] The adjustment mechanism 2 in this invention can be used not only in reversible plows, but also in other agricultural machinery that needs to be adapted to tractors of different models and connection point heights.
