Problems solved by technology

The forward and reverse gear transmission device can realize the forward and reverse operation of the rotary cultivator, but its transmission device has a complex structure, too many power transmission times, and only realizes the reverse rotation of the knife shaft, but does not realize the rotary tiller machete replacement. In the reverse direction, the blade cannot enter the soil when it is reversed

Embodiment 1

[0044] Such as Figure 1-8 As shown, the easy-to-adjust multi-rotation universal rotary tiller designed in this embodiment includes a frame 100, a gearbox 200 and a knife roller 300, wherein:

[0045] Such as image 3 , Figure 4 As shown, the gearbox 200 includes a gearbox housing 210 , a bevel gear train 220 and a spur gear train 230 .

[0046] The bevel gear train 220 includes two identical small bevel gears 221 and two identical large bevel gears 222; the two small bevel gears 221 are respectively mounted on the front and rear sides of the gearbox housing 210 through a small bevel gear shaft 223 ; Two large bevel gears 222 are installed on the left and right sides of the gearbox housing 210 through a large bevel gear shaft 224 respectively; each small bevel gear 221 meshes with two large bevel gears 222 simultaneously, and each large bevel gear 222 simultaneously Meshes with two small bevel gears 221 .

[0047] The spur gear train 230 includes a small spur gear 231 , a...

Embodiment 2

[0065] This embodiment describes the operation mode and power transmission method of the easy-to-adjust multi-rotation general-purpose rotary cultivator (using an asymmetric rotary cultivator roller) provided in Embodiment 1.

[0066] Operation mode one: such as Figure 9 In the power transmission mode shown, the surface of the frame 100A is connected to the power output shaft of the tractor through a universal joint. At this time, the front fender 610 is in the folded state, and the rear fender 620 is in the extended state. The position changes the depth depth of the depth gauge wheel 540 and connects the two half-clutches of the first clutch 240 through the operating mechanism 260 . At this time, the direction of rotation is as Figure 13 As shown by the arrow in the middle line, the asymmetric structure of the rotary tiller roller 300 is adopted, and the tangential cutting edge of the rotary tiller 330 is close to the ground surface during operation, and the normal rotatio...

Embodiment 3

[0071] This embodiment describes the operation process of the easy-to-adjust multi-rotation general-purpose rotary cultivator (using a double-sided symmetrical rotary cultivator roller) provided in Embodiment 1. The operation mode of this embodiment is exactly the same as that of Embodiment 2, and the difference is only in the type of the rotary blade roller 300 .

[0072] when using Figure 9 In the power transmission mode shown, the status of the rotary tiller is as follows Figure 15 As shown, the rotation direction is shown by the solid arrow in the figure, and the forward rotation operation is performed (that is, the rotation direction is the same as that of the tractor wheel, the same below).

[0073] when using as Figure 10 In the power transmission mode shown, the status of the rotary tiller is as follows Figure 16 As shown, the rotation direction is shown by the solid arrow in the figure, and the anti-rotation operation is performed (that is, the rotation directi...

Abstract

The invention discloses an easy-adjustable multi-rotation general-purpose rotary cultivator, which includes a frame, a gearbox and a knife roller; the frame adopts a front and rear symmetrical structure, and can be connected to a tractor from the front or rear for operation; the variable speed The box includes a gearbox housing, a bevel gear train and a spur gear train; the bevel gear train includes two small bevel gears and two large bevel gears; each small bevel gear meshes with two large bevel gears at the same time, each large bevel gear The bevel gear meshes with two small bevel gears at the same time; the spur gear train includes a small spur gear, a large spur gear and an output spur gear, and the three are meshed sequentially from top to bottom; the small spur gear is set on the two large bevel gears In the cavity surrounded by the two small bevel gears, a first clutch and a second clutch are respectively arranged between the two ends of the small spur gear shaft and the two large bevel gears, and both clutches are provided with operating mechanisms. The invention adopts a symmetrical frame and a reversible gearbox to realize forward and reverse operation and forward and backward reversing operation, and improves the efficiency of rotary tillage operation.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an easy-adjustable multi-rotation universal rotary tiller. Background technique [0002] The rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has the characteristics of strong soil breaking ability and smooth surface after plowing. Improve soil water storage and moisture conservation capacity, so it has been widely used. [0003] At present, most of the rotary tillage machines used in agricultural farming are forward-rotating rotary tillers, which adopt the single-axis knife-roller forward rotation method. This method has a high rate of straw embedding and uniform vertical space distribution, but the effect of returning to the field and the quality of land preparation are poor. In order to solve the above problems, a reverse rotary tiller has been developed. This type of rotary tiller has the advantages of stubble burying...
