Description

Technical Field

[0001] The utility model relates to the technical field of micro-tillers, in particular to a micro-tiller auxiliary wheel installation device. Background Art

[0002] In the existing farming operations, two-wheel micro-tillers are deeply loved by farmers in mountainous and steep terrains such as Sichuan, Guizhou, and Yunnan because they can be used in some places where large and medium-sized micro-tillers cannot reach, and they are cheap and durable. Basically, every household has such a micro-tiller. When the existing micro-tillers are in use, they generally have two working modes. One is that people follow the micro-tiller to operate; the other is that people sit on the micro-tiller to operate. In the first working mode, most micro-tillers only use the front-wheel working mode. For hard soil or soft soil that is prone to subsidence, this type of micro-tiller is difficult to work. In addition, it also requires physical strength from the operator because it is necessary to push or pull the micro-tiller to move forward at a constant speed for a long time. In the above soil conditions, the original two-wheel micro-tiller consumes a large amount of physical strength when in use and cannot work continuously for a long time, which makes the operator extremely uncomfortable.

It also includes a transition piece connected to the quick connector 3, a gearbox 6 fixedly connected to one end of the transition piece and driven by a driving mechanism, and an auxiliary wheel 7 fixedly connected to the gearbox 6. A transition plate 5 fixedly connected to the transition piece is provided on the box body of the gearbox 6. Among them, the quick connector 3 uses the quick connector 3 in the original machine head 1, and the installation method of the transition piece and the quick connector 3 uses the installation method in the existing connection methods, such as rotatably connecting one end of the transition piece in the U-shaped plate of the quick connector 3 in the form of a pin; and the gearbox 6 uses a common gearbox 6. The structure for the driving mechanism to start the gearbox 6 can adopt the following four types: One is to directly use an external power source (such as a small engine) to start the structure installed in the gearbox 6; the second is that there is an output port 12 in the engine in the original machine head 1 (that is, an output port 12 at the rear end of the original micro-tiller), and connect this output port 12 through a transmission flexible shaft or a transmission rigid shaft, and the other end is connected to the input end of the gearbox 6, so as to realize the start of the gearbox 6; the third is to connect a generator to an output port 12 at the rear end of the original micro-tiller, and then connect the generator to the motor 9 installed on the gearbox 6 to start; the fourth is to connect a hydraulic pump to an output port 12 at the rear end of the original micro-tiller, and then connect the hydraulic pump to a hydraulic motor, and the output end of the hydraulic motor is connected to the input end of the gearbox 6 installed (related hydraulic components are omitted); thereby realizing the rotation of the auxiliary wheel 7; among them, the auxiliary wheel 7 can be a spike-shaped wheel or a smooth anti-sinking wheel (the corresponding auxiliary wheel can be used according to different working scenarios), so as to facilitate the micro-tiller to work on hard soil or soft or sandy soil that is prone to subsidence; The utility model adds an auxiliary wheel on the basis of not changing the original structure of the two-wheel drive micro-tiller, that is, while retaining the work convenience of the original two-wheel drive micro-tiller in extremely small plots, it ensures the work quality of the micro-tiller on hard soil or soft soil that is prone to subsidence and improves the comfort of the operator.

[0026] In this embodiment, the transition piece includes a adapter connected to the quick connector 3 and a connecting rod 4 fixedly connected to the adapter. The connecting rod 4 is connected to the gearbox 6, and a functional interface 8 is provided on the connecting rod 4, so as to facilitate the installation of functional devices such as a pesticide sprayer, a seeder, and a film mulching machine.

[0027] Working principle of Embodiment 1: When encountering hard soil or soft soil prone to subsidence, only the auxiliary wheel 7 needs to be replaced with a spike-shaped wheel or a smooth anti-sinking wheel, and then the transition piece is connected to the quick connector 3; therefore, without changing the original structure, the present utility model adds the auxiliary wheel 7, thus ensuring the working quality of the micro-tiller for hard soil or soft soil prone to subsidence; in addition, since the auxiliary wheel 7 rotates at a constant speed, there is a pushing or pulling force to stabilize the forward speed of the front micro-tiller. At this time, it is not necessary to control the forward speed manually, which greatly saves the physical strength of the operator.

[0028] Embodiment 2: Please refer to Figure 2 , a micro-tiller auxiliary wheel installation device, which is different from Embodiment 1 in that the transition piece further includes a connecting plate 13 fixedly connected to the connecting rod 4.

The first adjusting column 16 is fixedly connected to the transition plate 5. A number of first through holes 17 are provided in alignment on the first adjusting column 16 and the first adjusting rod 14. The first limiting rod 15 penetrates through two aligned first through holes 17 at the same time. By adjusting the through hole on the first adjusting rod 14 to align with different positions of the first through holes 17 on the first adjusting rod 14, the distance between the tool wheel 11 and the auxiliary wheel 7 can be adjusted, so as to realize rotary tillage on different soil qualities or different slopes; the adjustment of the distance between the tool wheel and the auxiliary wheel can better adapt to different working conditions. When the soil is hard and the slope is large, the front and rear wheelbase needs to be larger. When the soil is soft and the slope is small, the wheelbase needs to be smaller; in addition, a functional interface is added to one end of the first adjusting rod 14 away from the connecting plate 13 to improve the use performance of the present utility model.

[0029] The first adjusting column 16 is provided with a threaded column. The first limiting rod 15 is threadedly connected to the threaded column. There are two first adjusting rods 14, and the gearbox 6 is located between the two first adjusting rods 14, which improves the connection strength between the first adjusting column 16 and the first adjusting rod 14; the cross section of the first adjusting rod 14 is square, which is convenient for adjusting the distance between the tool wheel 11 and the auxiliary wheel 7; in addition, in the starting mode of the gearbox 6, compared with Embodiment 1, different lengths of transmission flexible shafts or transmission rigid shafts can be replaced to achieve the same, and the remaining starting modes are the same; differential locking separators can be arranged on the two output ends of the gearbox 6, so that the rotation speeds of the auxiliary wheels 7 at both ends of the gearbox 6 are inconsistent, so as to achieve the effect of turning or turning around, thereby reducing the labor intensity of workers. Among them, the differential locking separator can adopt common speed adjusting parts, and will not be elaborated here.

The second limiting rod 27 penetrates through two aligned second through holes at the same time. A limiting hole is provided on the second limiting rod 27, and a limiting pin 26 is inserted into the limiting hole, so as to realize the adjustment of the distance between the two auxiliary wheels 7, and further adapt to rotary tillage knives of different widths, and the wheels can be adjusted to walk in the ditch or on the ridge when ditching or ridging; thereby improving the flexibility of the device; and a ridging plow 23 is adjustably connected to the second adjusting rod 20. Among them, the adjustable connection can adopt a common installation form of the ridging plow 23, such as attached Figure 4 As shown, no more details will be elaborated in this article.
