Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tillage equipment, and particularly relates to a ride-on micro-tiller. Background Art

[0002] A rotary tiller is a tillage machine that completes tilling and weeding. It has been widely used because of its strong soil crushing ability and flat surface after tilling. The basic principle of a rotary tiller is to use a rotating cutter head to deeply plow, loosen, and turn over the land through a special structure of the machine body.

[0003] The original walking rotary tiller can meet the needs of most individual users, but it requires a lot of physical strength to operate, and the operation is complicated with a high risk factor. Based on this, there are also track-type ride-on rotary tillers with low labor intensity and high efficiency on the market. However, due to their complex structure, they can only handle relatively flat ground, and have high maintenance difficulty and high price, so they do not meet the requirements of ordinary individual users. Based on this, a ride-on micro-tiller with high comfort and suitable for complex terrains is needed. Summary of the Utility Model

[0004] I. Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a ride-on rotary tiller, which miniaturizes the rotary tiller and has better terrain adaptability by changing the position and structure of the rotary tillage mechanism.

[0006] II. Specific Technical Solutions

[0007] A ride-on rotary tiller includes a mounting frame. Above one end of the mounting frame is provided a seat, and below the seat is provided a steering wheel group. In the middle section of the mounting frame is provided a direction adjustment mechanism for adjusting the turning angle of the steering wheel group. At the other end of the mounting frame is provided a power mechanism, which includes an engine and a reducer. The engine is installed on the housing of the reducer, and the output end of the engine is connected to the input end of the reducer. The reducer includes a first output end and a second output end extending out of the housing. The first output end is used to connect a drive wheel, and the second output end is used to connect a rotary tillage mechanism. The rotary tillage mechanism is located between the drive wheel and the steering wheel group. A protective cover is also fixedly provided on the housing, and the protective cover covers the side of the rotary tillage mechanism close to the seat.

[0008] Implementation Principle, Working Principle:

[0009] Different from the prior art, in this solution, the rotary tillage mechanism is arranged between the steering wheel set and the driving wheels, making the structure of the rotary tiller more compact as a whole; when operating the rotary tiller, people sit on the seat, which has a lower labor intensity compared with the way of walking and operating the rotary tiller. At the same time, the weight of the operator himself and the self-weight of the power mechanism are distributed on both sides of the installation frame, making the rotary tiller more balanced; the protective cover arranged between the rotary tillage mechanism and the seat can effectively prevent the soil lifted during tillage from affecting the operator.

[0010] Preferably: an installation end is further arranged at the lower part of the housing, the installation end is rotatably connected to the installation frame, and a hydraulic cylinder is further arranged on the installation frame. The two ends of the hydraulic cylinder are respectively hinged to the middle section of the installation frame and the upper part of the housing; the beneficial effect of this preference is that the telescopic movement of the hydraulic cylinder can drive the power mechanism and the rotary tiller to rotate around the installation frame, thereby controlling the tillage depth of the rotary tillage mechanism.

[0011] Preferably: a pedal is further arranged in the middle section of the installation frame, and the pedal is located on both sides of the direction adjustment mechanism; the beneficial effect of this preference is that through the setting of the pedal, the operator does not need to step on the protective cover, which is safer. The setting of the protective cover can prevent the soil lifted during tillage from affecting the operator.

[0012] Preferably: the steering wheel set includes two steering wheels connected by a wheel rod, and a steering shaft is fixedly arranged in the middle of the wheel rod; the direction adjustment mechanism includes a steering gear, the top of the steering gear is rotatably matched with a steering wheel, the output end of the steering gear is horizontally rotatably connected with a steering rod, and the other end of the steering rod is rotatably connected with a steering arm, and the other end of the steering arm is fixedly connected with the steering shaft.

[0013] Preferably: the installation end is a rotating sleeve fixedly arranged on the housing, and the first installation end is located on the axis line of the installation end; a hoop is further arranged at one end of the installation frame for installing the power mechanism, and the installation end is rotatably connected with the hoop; the beneficial effect of this preference is that by arranging the first installation end in the rotating sleeve, there are fewer redundant structures on the housing and it is more compact. The setting of the hoop can better install the installation end on the installation frame, which is simple and convenient.

[0014] Preferably: the installation frame includes a first installation section, a second installation section and a third installation section with gradually decreasing heights. The first installation section is used for installing the seat and the steering wheel set, the second installation section is used for installing the direction adjustment mechanism, an installation frame is arranged on one side of the second installation section close to the third installation section, and the third installation section is used for installing the power mechanism; the beneficial effect of this preference is that through the setting of this installation frame, the distribution of each component on it is more reasonable and coordinated, meeting the requirements of industrial design.

[0015] Preferably, mounting ears are provided on the top of the housing and the mounting frame respectively, and both ends of the hydraulic cylinder are pivotally connected to the mounting ears; the beneficial effect of this preference is that the two ends of the hydraulic cylinder are connected in a pivotal manner, and the hydraulic cylinder will rotate more smoothly when telescoping.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. In this solution, one engine can simultaneously provide power for the rotary tillage mechanism and the drive wheels through the two output ends of the reducer, which can make full use of the power of the engine, is conducive to maximizing energy utilization, and is more environmentally friendly.

[0018] 2. In this solution, the hydraulic cylinder drives the power mechanism to rotate around the hoop on the third mounting section, which can adjust the height of the rotary tillage mechanism thereon from the ground to be tilled, and can meet different tillage requirements, with stronger practicability.

[0019] 3. The rotary tillage mechanism is arranged between the drive wheels and the steering wheels, which is conducive to miniaturization of the rotary tiller and stronger adaptability to terrain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1 - 5 shown:

[0029] A ride-on rotary tiller includes an installation frame 1. The installation frame 1 includes a first installation section 101, a second installation section 102, and a third installation section 103 from right to left. The heights of the first installation section 101, the second installation section 102, and the third installation section 103 decrease in sequence. Between the first installation section 101 and the second installation section 102, and between the second installation section 102 and the third installation section 103, they are connected by inclined connecting rods, specifically, they can be connected by integral molding, welding, etc. The advantage of such a setting is that it is convenient to reasonably allocate the positions of each part of the structure.

[0030] During implementation, a seat 2 is provided at the upper end of the first installation section 101. A shock absorber can be provided between the seat 2 and the first installation section 101 to reduce the vibration during the operation of the ride-on rotary tiller and improve the comfort. A wheel axle mounting seat 301 is welded directly below the first installation section 101. The wheel axle mounting seat 301 is used to mount a steering wheel set 3. The steering wheel set 3 includes two steering wheels 303 connected by a wheel rod 302. A steering shaft 304 is fixedly connected to the middle of the wheel rod 302. The steering shaft 304 passes through the wheel axle mounting seat 301 and is hinged to the wheel axle mounting seat 301 or connected by tapered roller bearings. Such a connection method is convenient for adjusting the steering wheel set 3 to achieve steering.

[0031] During implementation, an installation frame 104 is vertically welded or formed at the front end of the second installation section 102. A direction adjustment mechanism 4 is provided on one side of the installation frame 104 close to the seat 2. The direction adjustment mechanism 4 includes a steering gear 401. The top of the steering gear 401 is rotatably fitted with a steering wheel 402. The output end of the steering gear 401 is horizontally rotatably connected to a direction pull rod 403. The other end of the direction pull rod 403 is rotatably connected to a direction arm 404. The other end of the direction arm 404 is fixedly connected to the upper end of the steering shaft 304. Its operating principle is that the steering gear 401 converts the rotation of the steering wheel 402 into the rotation of the direction pull rod 403, and then drives the direction arm 404 and the steering shaft 304 to rotate, realizing the angle adjustment of the steering wheel set 3 and achieving steering. During implementation, a pedal 105 is also welded on the second installation section 102. The pedal 105 is located on both sides of the direction adjustment mechanism 4.

[0032] During implementation, the third installation section 103 is for the power mechanism 5 and the rotary tillage mechanism 6. The power mechanism 5 includes an engine 501, and the engine 501 can specifically be a diesel engine or a gasoline engine. The engine 501 is connected to a speed reducer 502 through a flange, and the output end of the engine 501 and the input end of the speed reducer 502 are connected through a coupling;

[0033] Specifically, the speed reducer 502 includes a housing 503 and an installation end 504, a first output end 505, and a second output end 506 provided on the housing. Among them, the housing 503 is integrally L-shaped between the first output end 505 and the second output end 506. The first output end 505 and the second output end 506 are output shafts extending out of the housing 503. The installation end 504 is a rotating sleeve formed on the housing 503. Specifically, the first output end 505 is located at the axis of the installation end 504. A driving wheel 507 is connected to the first output end 505, and the second output end 506 is used to connect to the rotary tillage mechanism 6. The advantage of such a setting is that the power provided by the engine 501 is distributed to the driving wheel 507 and the rotary tillage mechanism 6 through the speed reducer 502, providing power for the walking of the rotary tiller and the operation of the rotary tillage mechanism 6.

[0034] During implementation, a hoop 106 is welded or integrally formed at the end of the third installation section 103. The hoop 106 cooperates with the installation end 504, and the installation end 504 can rotate within the hoop 106. During implementation, installation ears 508 are provided on the top of the installation frame 104 and the housing 503 of the speed reducer 502. The installation ears 508 are for installing the hydraulic cylinder 7. In this solution, the top of the hydraulic cylinder 7 is connected to the installation ear 508 in a pivoting manner, and the base of the hydraulic cylinder 7 is connected to the installation ear 508 of the speed reducer 502 in a pivoting manner. The advantage of such a setting is that the telescoping of the hydraulic cylinder 7 can drive the housing 503 to rotate around the hoop 106, thereby changing the angle of the second output end 506 at the other end of the housing and directly adjusting the angle of the rotary tillage mechanism 6 to achieve the adjustment of the rotary tillage depth.

[0035] During implementation, a protective cover 509 is detachably installed on one side of the second output end 506 of the housing 503. The protective cover covers the upper half of the rotary tillage mechanism 6. The advantage of this is to prevent soil from entering from the second installation section 102 during rotary tillage and affecting the operation of the operator.
