Abstract
Description
Technical Field
[0001] The utility model belongs to the application field of agricultural and pastoral machinery, and particularly relates to a foldable suspended cutting and flattening machine capable of realizing the combined operation of forage cutting, flattening and strip laying in natural pastures and artificial pastures. The cutting machine is an important working component of various forage harvesting machines. At present, there are two common types of cutting machines used in various forage harvesting machines: reciprocating type and rotary type. The rotary cutting machine belongs to unsupported cutting, does not cause blockage, and is easy to replace the blade. The rotary cutting machine has strong adaptability to forage, especially suitable for dense and lodged forage, and has the characteristics of stable working performance and high productivity. Background Art
[0002] Forage harvesting is an important link in the production of the grass industry. Improving the mechanization level and productivity of forage harvesting is extremely important for ensuring a good harvest in the grass industry. In the prior art, common forage harvesting machines have problems such as inconvenient transportation and storage, uneven cutting stubble height, and poor gathering effect. The utility model can effectively solve the above problems. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a foldable suspended cutting and flattening machine that combines economy, practicability and convenience, which can carry out cutting, flattening and strip laying operations on forage, and at the same time, by folding the machine, the transportation volume can be reduced.
[0004] The purpose of the utility model is realized by the following technical solutions:
[0005] A foldable suspended cutting and flattening machine mainly consists of a mowing table, a flattening device, a grass guard support frame, a folding and recycling device, a floating profiling device, a main beam, a suspension bracket and a strip laying device; the suspension bracket is connected to the main beam, the main beam is connected to the flattening roller frame and the mowing table, the mowing table is installed at the front end of the machine, the flattening device is installed in the middle of the machine, which is divided into an upper flattening roller and a lower flattening roller. The two flattening rollers are composed of multiple sections of rubber spiral teeth and form meshing, and the lower flattening roller drives the upper flattening roller to rotate. The strip laying device is installed at the rear of the machine.
[0006] The folding and recycling device can rotate the mowing table and the flattening device around the two-stage gearbox, fold the main body of the machine perpendicular to the ground, which is convenient for transportation and storage. At the same time, in order to achieve folding, the grass guard support frame also has a foldable design.
[0007] The floating profiling device can work on uneven ground with the help of a tension spring and a hydraulic rod, and ensure that the cutting stubble height is basically the same.
[0008] The flattening device consists of an upper flattening roller and a lower flattening roller. The shaft roller side plate is provided with a quick-release structure at the installation interface of the lower flattening roller, which can quickly and conveniently disassemble the lower flattening roller for timely replacement according to needs.
[0009] The described straw laying device consists of straw laying baffles on both sides and a canvas rear cover. The straw laying baffles can adjust the opening and closing angle according to the actual situation, thereby changing the straw laying width.
[0010] The described flattening device transmits power through the flattening roller transmission shaft, which is convenient for disassembly and replacement, and the whole flattening device can be removed. At this time, the machine can only complete the mowing operation according to actual needs without performing the flattening process.
[0011] The utility model is used in conjunction with a tractor. When working, the traction plate of the tractor is hooked to the suspension frame of the utility model, and the power output shaft of the tractor is connected to the first-stage gearbox. When working, the machine is driven and towed by the tractor. The mowing table cuts the forage from the root, and then feeds the forage into the flattening device through the mowing table. The forage passes between the upper flattening roller and the lower flattening roller to complete the flattening operation, and then is thrown out by the straw laying device. The baffles on both sides of the straw laying device can manually adjust the straw laying width to complete the straw laying operation according to needs. Description of the Drawings

Detailed implementation mode
[0021] The present utility model will be further described with reference to the accompanying drawings:
[0022] The present utility model provides a foldable suspended cutting and flattening machine that can perform cutting, flattening, and strip laying operations on forage grass, mainly composed of a mowing table (1), a flattening device (2), a protective cover support beam (3), a folding and recycling device (4), a floating profiling device (5), a primary gearbox (6), a safety hanging plate (7), a main beam (8), an adjusting pull rod (9), a leg support (10), a suspension bracket (11), a U-shaped frame (12), a strip laying device (13), a belt drive device (14), an inner slide plate (15), an external spline transmission shaft (16), and a flattening roller transmission shaft (17).
[0023] The protective cover support beam (3) provides support for the grass curtain support frame (4-1), the secondary gearbox (4-2) connects the mowing table (1) and the main beam (8), and the leg support (10) is used for the support when the present utility model is stationary; the suspension bracket (11) and the U-shaped frame (12) are used for connection with a tractor, the power output shaft of the tractor is connected to the external spline transmission shaft (16) of the primary gearbox (6) through a universal joint, the primary gearbox (6) transmits power to the secondary gearbox (4-2) and the lower flattening roller (2-3) respectively through the belt drive device (14) and the flattening roller transmission shaft (17), and then the lower flattening roller (2-3) drives the upper flattening roller (2-2) to rotate, and the secondary gearbox (4-2) transmits power to the mowing table (1) through a gear set, so as to achieve cutting and flattening; since the power inputs of the flattening device (2) and the mowing table (1) are independent of each other, when the flattening operation is not required, the flattening device (2) can be removed without affecting the operation of the mowing table (1).
[0024] During the operation of the utility model, the inner slide plate (15) provides protection for the mowing platform to prevent the blade from cutting into the soil due to uneven ground. At the same time, the tension spring (5-1) and the hydraulic rod (5-2) in the floating profiling device (5) cooperate with the adjusting pull rod (9) to realize the floating profiling function of the utility model.
[0025] The folding of the implement is mainly achieved through a hydraulic rod (5-2) and a safety hanging plate (7). The hydraulic rod (5-2) lifts the mowing platform (1), the flattening device (2) and the strip laying device (13), and the safety hanging plate (7) is docked and locked with the bayonet on the protective cover support beam (3), thereby achieving the folding of the utility model. In the folding recovery device (4), the grass curtain support frame (4-1) adopts a two-stage structure, with the secondary gear box (4-2) as the rotation center, to complete the folding of the implement.
[0026] After being thrown out from the flattening device (2), the material collides with the canvas rear cover (13-2) and the grass-laying baffle (13-1) and then falls to the ground. The grass-laying baffle (13-1) can be adjusted according to the requirements of the grass-laying width to change the opening and closing angle.
[0027] The flattening device (2) achieves reverse and synchronous rotation through meshing transmission, the mowing table (1) cuts the grass and feeds it into the meshing gap, and the flattening device (2) flattens the grass; since the lower flattening roller (2-3) is more susceptible to damage than the upper flattening roller (2-2), and there are blockages and jams caused by picking up foreign objects during the operation of the machine, a quick-release design is adopted at the installation interface of the lower flattening roller (2-3) to facilitate cleaning and maintenance.
