Problems solved by technology

The arrangement in the middle of the transmission box results in a space for the rotary tiller in the middle, and the soil in the middle cannot be rotated, etc.
In addition, when the existing rotary tiller is cultivating the soil, due to the problem of the power arrangement and the center of gravity of the machine, the center of gravity of the machine moves backward, which is not conducive to the stable cultivation of the machine, resulting in uneven and uneven depth of cultivated land.
In addition, in the existing multi-link tensioning mechanism, the operating rod vibrates greatly, the power system is noisy, the operation is inconvenient, and the operation is difficult.
[0004] In the part of the crawler running mechanism of the existing rotary tiller, the driving wheel of the crawler running mechanism and the rotating shaft are connected by simple bolts. During the running process of the crawler running mechanism, the driving wheel is easy to loosen, and the bolts and the driving wheel fall into the paddy field. , causing the rotary tiller to be unable to walk
[0005] In the rotary tiller part of the existing rotary tiller, the rotary tiller cannot be lifted up and down, that is, the depth of the rotary tiller cannot be automatically adjusted. The scraping plate is frequently hit and jumps up and down, making a lot of noise

Embodiment Construction

[0041] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0042] Such as Figure 1 to Figure 13 Shown, the present invention preferably has a kind of forward and reverse gearbox and forward and reverse rotary cultivator. The hinge mentioned in the present invention refers to the connection structures that can rotate with each other.

[0043] Such as figure 1 As shown, a kind of forward and reverse rotary tiller comprises a rotary tiller chassis and a rotary tiller 5, the rotary tiller 5 is installed at the rear of the rotary tiller chassis, and a counterweight is installed at the front of the rotary tiller chassis (Fig. not shown). The counterweight can balance the front, back, left and right sides of the rotary tiller to ensure the smooth operation...

Abstract

The invention discloses a positive inversion gearbox and a positive inversion rotary cultivator. The gearbox comprises an input shaft, an output shaft, a middle shaft and a reversing mechanism which are arranged on a shell body, and the input shaft, the output shaft and the middle shaft are arranged in a triangle mode; an input gear is arranged on the input shaft, a forward output gear and a reversing output gear are arranged on the output shaft, a middle gear is arranged on the middle shaft, and the forward output gear is meshed with the middle gear; when the input gear is in a normal tap position, the input gear is meshed with the middle gear, power of the input shaft is transmitted to the output shaft through the input gear, the middle gear and the forward output gear, and forward rotation is achieved; when the input gear is in a reversing gap position, the input gear is meshed with the reversing output gear, power of the input shaft is transmitted to the output shaft through the input gear and the reversing output gear, and reversing is achieved; the reversing mechanism toggles the input gear to move from the forward gap position and the reversing gap position. According to thepositive inversion gearbox, forward and reversing ploughing operation can be achieved, and a chain is tensioned in the forward and reversing direction.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a forward and reverse gearbox and a forward and reverse rotary cultivator. Background technique [0002] Rotary tiller is a kind of soil tillage machine driven by power. It has strong ability to cut soil and crush soil. It can achieve the effect of plowing and raking several times in one operation. With the continuous improvement of the level of agricultural science and technology, it has become a common method to complete the rotary tillage of farmland soil by rotary tiller. As we all know, the operating principle of the rotary tiller is to use the rotary tiller shaft to loosen and mash the mud (or clods) to achieve the purpose of tillage. The rotation direction of the existing rotary tiller shaft is a single rotary motion, which cannot be realized in positive and negative directions. to rotate. Also can only realize the one-way chain tensioning in the transmission box th...
