Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural equipment, in particular to a pneumatic double-connecting rod regulating soil loosening mechanism. Background Art
[0002] Typically mounted on excavators or bulldozers, scarifiers perform functions such as crushing and loosening, primarily used to turn over soil. Scarifying is a fundamental task, and there's an urgent need for smaller, more versatile agricultural machinery suitable for protected land operations to replace manual labor and improve productivity. Therefore, rational and scientific scarifying is a key means of ensuring food security and maintaining sustainable agricultural development. Manual scarifying of fields is inefficient and expensive, and existing agricultural equipment for harvesting root crops requires pre-harvest scarification to facilitate easier extraction. To accommodate the loading requirements of this equipment, technicians in this field have designed a pneumatic, double-link adjustable scarifying mechanism. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pneumatic double-link adjustable soil loosening mechanism, which is convenient for use with agricultural equipment.
[0004] The technical solution of the utility model is: a pneumatic double-link adjustment loosening mechanism, including a mounting plate, a compressed air bottle arranged on the mounting plate, and two groups of loosening modules symmetrically arranged on the front side of the mounting plate, the loosening module including a driving cylinder, a connecting rod assembly and a loosening plow, the compressed air bottle is connected to the driving cylinder, the fixed end of the driving cylinder is arranged at the bottom of the mounting plate through a first loosening plow fixing frame, the output shaft of the driving cylinder is hinged to the connecting rod assembly, one end of the connecting rod assembly is connected to the mounting plate, and the other end is connected to the loosening plow.
[0005] As can be seen from the above scheme, the compressed air cylinder is used to achieve air compression, which is convenient for providing an air source for the driving cylinder, thereby extending the time for loosening the soil in the field. The driving cylinder is used to drive the movement of the connecting rod assembly, thereby driving the loosening plow to move up and down to achieve loosening. The loosening plow is used to loosen the soil in the field. The connecting rod assembly is used to convert the horizontal power of the driving cylinder into vertical movement of the loosening plow, thereby performing reciprocating motion to achieve loosening. The utility model is used for loosening the soil during the movement of the device, with the purpose of loosening the soil on both sides of the radish planting ridge, reducing the grip of the radish roots on the soil, and making it easier to pull up the radishes for subsequent work.
[0006] The connecting rod assembly includes a special-shaped connecting rod and a rotating shaft. One end of the rotating shaft is hinged to the first loosening plow fixing frame via a first pin, and the other end is connected to the special-shaped connecting rod. One end of the special-shaped connecting rod is connected to the second loosening plow fixing frame via a second pin, and the other end is connected to the loosening plow via a plow guide plate. The first loosening plow fixing frame and the second loosening plow fixing frame are arranged at the bottom of the mounting plate. The output end of the driving cylinder is connected to the shaft body of the rotating shaft via a mounting limit seat, and the output shaft is rotatably connected to the mounting limit seat via a spherical bearing. It can be seen that the connecting rod assembly and the output shaft of the driving cylinder form a quadrilateral connecting rod mechanism. The special-shaped connecting rod is used to drive the loosening plow to loosen the soil by lifting and lowering under the drive of the driving motor.
[0007] The special-shaped connecting rod includes an extension portion and a connecting portion integrally mounted on the extension portion, the angle between the extension portion and the connecting portion being obtuse, the rotating shaft being connected to the middle portion of the connecting portion, the extension portion being connected to the mounting plate, and the connecting portion being connected to the loosening plow. Thus, the loosening plow can be detachably mounted on the plowshare guide plate for easy disassembly and replacement.
[0008] The surface of the loosening plow transitions in an arc from inside to outside, and the thickness of the loosening plow gradually becomes thinner from top to bottom.
[0009] The plowshare guide plate includes a guide plate body and a mounting block, and the loosening plow is connected to the mounting block. BRIEF DESCRIPTION OF THE DRAWINGS
