Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

A multifunctional mini-tiller.

As shown in fig. 1, the machine comprises a machine base 1, wheels 2 and a tilling blade 3 are arranged on the machine base 1, a power device 4 for driving the tilling blade 3 to rotate is fixed at the rear part of the machine base 1, and a handrail 5 is obliquely arranged at the front part of the power device 4.

In some existing mini-tillers, the handrail 5 is often arranged behind the power device 4, and is similar to a structure of a small cart, so that the center of gravity of the whole mini-tillers is behind, and when the mini-tillers need to be lifted upwards or moved, the operation is laborious and inconvenient; in addition, due to the lever principle, in order to save labor, the handrail 5 serving as the power arm is often obliquely arranged and is relatively long, so that the length of the machine body is lengthened, the position of the handle 23 is difficult to reach when the tilling blade 3 is clamped and the body needs to be tilted forwards to hold the handle 23, and a relatively large space is required, which is disadvantageous to storage and transportation, and is particularly inconvenient when the machine body is too long in complex and various fields and forest lands.

This technical scheme overcomes above defect, with handrail 5 leading, power device 4 is installed in the below of handrail 5, handrail 5 slope promptly sets up, with frame 1 becomes certain angle, power device 4 installs in inclination, and reasonable ingenious utilization space has shortened the length of organism and has also guaranteed the length of handrail 5 as the power arm simultaneously, still very laborsaving and can be very easy hold and get handle 23 and carry out the organism adjustment.

Preferably, the machine base 1 comprises a bottom plate 6, the power device 4 is fixed on the bottom plate 6, the power device 4 comprises an engine 7, an output shaft 8 connected with the engine 7 and an oil tank 9, the oil tank 9 is arranged above the engine 7, and the tilling blade 3 is connected with the engine 7 through the output shaft 8; the handrail 5 is installed above the output shaft 8, and the handrail 5 is installed and positioned between the engine 7 and the tilling blade 3.

The wheels 2 are arranged below the engine 7, the distance between the wheels 2 is small, and the size of the machine body is reduced. One end of the output shaft 8 is connected with the engine 7, the other end of the output shaft is connected with the rotary tillage knife 3, a handle 23 is arranged in the middle of the tillage knife 3, and the handle 23 is installed on the output shaft 8. The middle parts of the engine 7 and the tilling blade 3 are provided with the handrails 5, and the gravity center of the technical scheme moves backwards, so that the whole mini-tiller has a backward tilting trend, and the mini-tiller is more convenient and labor-saving to push and walk; or the tilling blade 3 at the front end of the machine body is lifted up conveniently and labor-saving.

Traditional ploughing machine a little adopts parts such as power device 4 such as aluminium leg joint support engine 7 and ploughing sword 3, the utility model discloses an output shaft 8 adopts cast iron, has increased intensity, toughness and wearability.

Referring to fig. 2, the handrail 5 includes two handrail rods 10, and the two handrail rods 10 have higher strength, are more stable in parallel arrangement, and are easy to control. The top end of the grab bar 10 is provided with a handle 11 for holding, which comprises a left handle 11 and a right handle 11, a connecting cross rod is arranged between the left handle 11 and the right handle 11, and the end parts of the left handle 11 and the right handle 11 are sleeved with rubber sleeves. The handle 11 is used for being held by both hands of an operator to control the traveling direction and speed of the mini-tiller, and the handle 11 is provided with a clutch. Because the operating environment is complex and various, the mini-tiller can vibrate and shake when being operated, and an operator needs to hold the handle 11 hard to keep the body balance, so that the elbow and the shoulder are easy to fatigue; meanwhile, due to the blocking of the connecting cross rod, when an operator needs to lean forward to hold the handle 23, the operator has a supporting part without falling down, and the safety is higher.

The bottom end of the grab bar 10 is provided with an adjusting piece 12 for adjusting the height of the grab rail 5. The adjusting piece 12 comprises a mounting plate 13 fixedly arranged on the output shaft 8, and the mounting plate 13 is obliquely fixed with the handrail 5; the bottom end of the handrail 5 is symmetrically formed with a plurality of connecting parts 14, the connecting parts 14 are provided with connecting holes 15, one end of the mounting plate 13 close to the tilling blade 3 is hinged to the connecting parts 14, the other end of the mounting plate is hinged to the connecting parts 14 through an adjusting plate 16, and the adjusting plate 16 is provided with a plurality of adjusting holes 17.

This technical scheme discloses a simple structure adjusts convenient 5 altitude mixture control modes of handrail, can highly adjust handrail 5's terrain clearance according to the in-service use, adapts to operator's user demand, and is more convenient. The handrail 5, the mounting plate 13 and the adjusting plate 16 form a triangular structure, and the structure is more stable and firm.

The handrail 5, the mounting plate 13 and the adjusting plate 16 are connected through an articulated shaft 18, the articulated shaft 18 is a screw rod, and two ends of the articulated shaft 18 are fixed through bolts 19.

This technical scheme discloses a convenient fixed mode, it is all very convenient when installation and height-adjusting, only need to be used for the bolt 19 of fixed connection portion 14 and mounting panel 13 to unscrew, then will be used for the bolt 19 of fixed connection portion 14 and regulating plate 16 to pull down, adjusts in articulated shaft 18 inserts suitable regulation hole 17, need not to get off handrail 5 whole dismantlement, and is swift convenient, simple structure also be convenient for maintain.

The bottom end of the handrail 5 is provided with the connecting plate 20, so that the handrail has a certain protection effect on one hand, and the stability of the handrail 5 is enhanced on the other hand, the bottom end of the handrail 5 is used as the connecting part 14, so that the stress is large, and the connecting plate 20 increases the connectivity and the strength between the handrail rods 10.

A mudguard 21 is arranged between the handrail 5 and the tilling blade 3, the upper end of the mudguard 21 inclines towards the tilling blade 3, and the mudguard 21 is provided with a jack for penetrating the bottom end of the handrail 5. The jack is used for the front part of the bottom end of the handrail 5 to penetrate through, so that the space is reasonably utilized, the mudguard 21 can be far away from the tilling blade 3, the rotation of the tilling blade 3 is not influenced, namely, the mudguard 21 is not required to be arranged forwards due to the fact that the installation of the handrail 5 occupies the space, the tilling blade 3 is influenced to be arranged forwards, and the machine body is lengthened.

The utility model discloses a rotary tillage knife, including output shaft 8, tilling blade 3, tilling blade 22, tilling blade 3, tilling blade 22 is fan-shaped and to 8 both ends outsides of output shaft transversely extend aslope and extend, and the top inclination of blade 22 differs, and the angle of rotatory stirring is more extensive, impels laborsavingly more.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
