Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a grass cutter and flattener. Background Technology

[0002] A mower-flattener is a type of machinery specifically designed for harvesting forage, primarily used in crop farming and animal husbandry. The mower-flattener completes the functions of mowing and flattening in one pass, crushing and breaking up fresh forage and stalks with pressure rollers, accelerating internal moisture evaporation, shortening drying time, reducing nutrient loss, and improving hay quality.

[0003] Existing hay cutters typically have two pressure rollers: an upper roller and a lower roller, both usually fixed. The upper roller is generally adjustable to allow for changing the gap between the two rollers, making it suitable for different types and textures of hay. Although the upper roller is adjustable, once the gap between the upper and lower rollers is determined, the upper roller itself remains fixed. When the amount of hay being cut by the cutter suddenly increases, the pressure rollers cannot handle such a large influx of hay. Consequently, the cut hay accumulates in front of the pressure rollers and may fall to the ground because it cannot be processed into the rollers in time, thus losing its flattening function. Utility Model Content

[0004] Existing mower ballast machines cannot handle a sudden increase in the amount of harvested hay when the amount of hay increases dramatically. As a result, hay accumulates in front of the ballast and may fall to the ground because it cannot be quickly fed into the ballast, thus losing its ballasting function. This application designs a mower ballast machine, and the technical solution adopted is as follows:

[0005] A lawn mower and flattener includes a suspension frame connected to a traction mechanism, a cover mounted on the suspension frame, a cutting table and a power transmission mechanism mounted on the suspension frame, and further includes:

[0006] The lower pressure roller is rotatably mounted on the suspended frame and has a lower pressure block.

[0007] The upper pressure roller has an upper pressure block that meshes with the lower pressure block. The upper pressure roller is positioned above the lower pressure roller and its two ends pass through mounting holes on the suspension frame and are connected to two movable seats. The mounting holes are larger than the rotating shaft of the lower pressure roller. Each movable seat is connected to a swing plate. One end of the swing plate is rotatably mounted on the suspension frame, and the other end is rotatably connected to the lower end of a guide rod. The upper end of the guide rod moves through the suspension frame, and a spring is sleeved around the guide rod below the suspension frame.

[0008] Preferably, the lower and upper pressure blocks are herringbone-shaped rubber blocks.

[0009] Preferably, the machine cover includes a first cover body disposed above the cutting table and a second cover body disposed behind the upper pressure roller and the lower pressure roller, wherein the side plates of the second cover body near the two ends of the lower pressure roller or the two ends of the upper pressure roller are drawn inward.

[0010] Preferably, the side plate of the second cover is hinged to the suspension frame, the top plate of the second cover is provided with an arc-shaped locking hole, the top of the side plate of the second cover is provided with a connecting hole, and bolts are inserted into the connecting hole and the arc-shaped locking hole, and nuts are connected to the bolts.

[0011] Preferably, the power transmission mechanism includes:

[0012] A first drive shaft, on which a first pulley and a first gearbox are spaced apart, and the first gearbox is connected to the lower pressure roller in a drive connection.

[0013] The second drive shaft has a second pulley and a second gearbox spaced apart on it. A drive belt connects the second pulley and the first pulley, and the second gearbox is connected to the cutting table via a drive belt.

[0014] Preferably, the suspension frame includes a fixed frame and a movable frame. The fixed frame is used to connect with the traction machinery, the movable frame is hinged to the fixed frame, and a telescopic cylinder is hinged between the fixed frame and the movable frame.

[0015] Preferably, the fixed frame is equipped with support legs.

[0016] Preferably, the fixing frame is provided with a U-shaped connecting plate, and the two ends and the middle position of the U-shaped connecting plate are respectively provided with plug-in interfaces, and the three plug-in interfaces are arranged in a triangle.

[0017] This invention achieves the floating purpose of the upper pressure roller by setting a swing plate, guide rod and spring on the upper pressure roller. When the amount of hay harvested increases, the amount of hay flattened increases, which forces the upper pressure roller to move upward in a small range to increase the gap between the upper pressure roller and the lower pressure roller. The gap between the two is adjusted online in real time according to the amount of hay harvested, so as to avoid the hay from piling up in front of the pressure roller, and thus avoid the hay falling off without being flattened and thus losing the flattening effect.

[0021] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0022] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] like Figure 1-3 As shown, a grass cutter and ballast includes a suspension frame 1 connected to a traction mechanism, a cover 2 mounted on the suspension frame 1, a cutter head 10 mounted on the suspension frame 1, and a power transmission mechanism 8. The traction mechanism can be a tractor. The power transmission mechanism 8 is drive-connected to the cutter head 10, driving the cutter head 10 to harvest grass. The cutter head 10 has a built-in cutter, and its structure is prior art; therefore, its structure will not be described in detail here.

[0024] In addition, it also includes a lower pressure roller 9 and an upper pressure roller 12. The two ends of the lower pressure roller 9 are mounted on the suspension frame 1 through bearings. The rotating shaft of the lower pressure roller 9 is also connected to the power transmission mechanism 8. The power transmission mechanism 8 drives the cutter 10 to harvest the forage while also driving the lower pressure roller 9 to rotate. The lower pressure roller 9 is provided with a lower pressure block, and the upper pressure roller 12 is provided with an upper pressure block. The upper pressure block meshes with the lower pressure block, so that the upper pressure roller 12 rotates passively.

[0025] The upper pressure roller 12 is positioned directly above the lower pressure roller 9, with both ends passing through mounting holes on the suspension frame 1 and corresponding to two movable seats 4. The mounting holes are larger than the pivot of the lower pressure roller 9, ensuring that the lower pressure roller 9 can move slightly within the mounting holes. Each movable seat 4 is connected to a swing plate 5, one end of which is hinged to the suspension frame 1, and the other end is hinged to the lower end of a guide rod 6. The movable seat 4 is also connected to the swing plate 5 near this end. The guide rod 6 is vertically positioned, with its upper end movably passing through the suspension frame 1. A spring 7 is fitted around the guide rod 6 below the suspension frame 1. As the amount of harvested hay increases, the pressure between the lower pressure roller 9 and the upper pressure roller 12 increases. External force compresses the spring 7, causing the guide rod 6 to move upward. The movable seats 4 rotate clockwise around the junction, ultimately causing the upper pressure roller 12 to move upward, increasing the gap between it and the lower pressure roller 9, and increasing the amount of hay pressed in.

[0026] Furthermore, the aforementioned lower and upper pressing blocks are "V"-shaped rubber blocks. The V-shaped rubber blocks not only transmit power but also cause the hay to be flattened and rolled inward, thus bringing the flattened hay closer to the center and preventing it from being rolled over by the wheels.

[0027] Furthermore, the aforementioned cover 2 specifically includes a first cover 201 disposed above the cutter 10 and a second cover 202 disposed behind the upper pressure roller 12 and the lower pressure roller 9. The first cover 201 can prevent the cut hay from scattering everywhere and can also reduce dust. The side plates 202c of the second cover 202 near the two ends of the lower pressure roller 9 or the two ends of the upper pressure roller 12 are drawn inward. Under the action of the second cover 202, the flattened hay is drawn inward to the center to avoid being too scattered.

[0028] Furthermore, to facilitate adjustment of the retraction angle of the side plate 202c of the second cover 202, the side plate 202c of the second cover 202 is hinged to the suspension frame 1. The top plate 202a of the second cover 202 is provided with an arc-shaped locking hole 202b, and the top of the side plate 202c of the second cover 202 is provided with a connecting hole. Bolts (not shown due to assembly reasons) are inserted into the connecting hole and the arc-shaped locking hole 202b. The bolts are connected to nuts 202d. When it is necessary to strengthen the retraction, loosen the nuts 202d, rotate the side plate 202c inward until it reaches the appropriate position, and tighten the screws to fix the side plate 202c. Conversely, rotate the side plate 202c outward.

[0029] Furthermore, the aforementioned power transmission mechanism 8 specifically includes a first transmission shaft 801 and a second transmission shaft. A first pulley 802 and a first gearbox 805 are spaced apart on the first transmission shaft 801. The first gearbox 805 is connected to the lower pressure roller 9. The first gearbox 805 includes spur gears and bevel gears that work together to achieve transmission and reversal, thereby driving the lower pressure roller 9 to rotate. A second pulley 803 and a second gearbox 806 are spaced apart on the second transmission shaft. A transmission belt 804 connects the second pulley 803 and the first pulley 802. The second gearbox 806 is connected to the header 10. The first pulley 802 drives the second pulley 803 to rotate, which in turn drives the second gearbox 806 to transmit power to the header 10, which then harvests the forage.

[0030] Furthermore, the aforementioned suspension frame 1 includes a fixed frame 2 and a movable frame 102. The fixed frame 2 is used to connect with the traction machinery, and the movable frame 102 is hinged to the fixed frame 2, so that the movable frame 102 can rotate around the hinge. A telescopic cylinder 3 is hinged between the fixed frame 2 and the movable frame 102, thereby realizing the folding of the movable frame 102 between the vertical and horizontal positions. When driving on a narrow road, the movable frame 102 can be folded to the vertical position and lowered to the horizontal position when working.

[0031] Furthermore, in order to maintain the stability of the entire suspension frame 1 when connected to the traction machinery, a support leg 11 is provided on the fixed frame 2 to facilitate connection with the traction machinery.

[0032] Furthermore, the fixed frame 2 is provided with a U-shaped connecting plate 13, and the two ends and the middle position of the U-shaped connecting plate 13 are respectively provided with plug-in interfaces 14. The three plug-in interfaces 14 are arranged in a triangle. When connected with traction machinery, the connection at the three positions improves the connection stability.

[0033] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0034] Any aspects of this utility model not described in detail are known to those skilled in the art.
