Description

A hand-held small deep cultivator

technical field

The utility model relates to a soil plowing agricultural implement, in particular to a hand-held small deep plowing machine with a plowing depth of more than 30 cm. the

Background technique

Rotary tillers are widely used in my country because of their good soil cutting effect and strong soil crushing ability. At present, the tillage depth of the micro-rotary tillers sold in the market is generally 12~20cm. The use of this kind of shallow tillage tiller for soil cultivation for many years will cause the land to be shallow, and a hardened plow bottom layer will be formed under the shallow tillage layer, which will affect the quality of the soil. The root system of crops is stuck down, and the infiltration of water and fertilizer is difficult. Deep plowing can realize soil plowing, loosening and mixing, and break the bottom layer of the plow, so as to restore the soil aggregate structure and enhance the function of soil water storage and moisture conservation. the

Patent application number "201020237884.X" and a Chinese utility model titled "self-propelled double-shaft deep tiller" disclose a deep tiller, which consists of a frame, a deep tiller blade, a deep tiller shaft, a pulverizer, a pulverizer shaft, a variable speed The input shaft in the gearbox is connected to the rear output shaft of the tractor, and the hydraulic lifter of the tractor is connected to the frame of the device; The box has two power output shafts, one is connected to the deep tiller shaft, the other is connected to the crushing knife shaft, and the deep tiller is evenly installed on the deep tiller shaft. During deep plowing, the rear output shaft of the tractor drives the device to work. The rotating speed of the deep plowing knife shaft of the device is relatively slow, only 25 revolutions per minute. Row of subtilizers and push the tractor while cutting the ground. This kind of deep cultivator is a supporting implement of a four-wheel ride-on tractor, which requires a large supporting power, and the volume and weight of the implement itself are relatively large, so it is not suitable for use in small plots and hilly areas. the

Contents of the invention

In view of the above-mentioned deficiencies existing in the existing deep cultivating machines, the purpose of the utility model is to provide a hand-held small deep cultivating machine with strong terrain adaptability, and its plowing depth can reach more than 30cm. the

The technical solution of the utility model is realized in the following way: a hand-held small deep tiller, including an internal combustion engine, a gearbox, a walking wheel, a transmission box and a rotary tiller, the output of the internal combustion engine is connected to the gearbox, and the gearbox is connected to the walking wheels, The gearbox is connected to the rotary tiller through the transmission box at the same time, and the feature is that: the rotary tiller is composed of two sets of cutters, the shallow tiller and the deep tiller, and the axis of the deep tiller is located behind the axis of the shallow tiller. Offset downward by a certain distance. the

The direction of rotation of the walking wheel and the shallow plowing blade is the same, and the rotation direction of the deep plowing blade is opposite to that of the shallow plowing blade. the

The lateral length of the deep cultivating blade is smaller than that of the shallow cultivating blade. the

The shallow cultivating knife is composed of a left shallow cultivating knife and a right shallow cultivating knife symmetrically arranged on the left and right sides of the transmission box. the

Compared with the prior art, the utility model has the following beneficial effects:

1. It has changed the plowing effect of the current small and micro rotary tillers. The shallow plowing and sub-loosening and layering operations are completed at the same time, and the plowing depth can reach more than 30cm.

2. The rotation direction of the deep plowing blade is opposite to that of the shallow plowing blade, and a force opposite to the forward direction is generated during deep plowing to facilitate deep plowing and control the speed of the plowing machine. At the same time, the direction of rotation is opposite, so that the reaction forces of the two cutting soil cancel each other out, the machine runs smoothly, and the machine is easier to control during tillage. the

3. The depth of deep plowing can be adjusted by adjusting the vertical offset distance between the deep plowing knife and the shallow plowing knife, which is flexible and convenient. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. the

Referring to Fig. 1, as can be seen from the figure, the utility model walk-behind small deep cultivator mainly consists of an internal combustion engine 1, a gearbox 2, a walking wheel 3, a transmission case 4, a shallow plow blade 5, and a deep plow blade 6. The output of the internal combustion engine is connected to the gearbox, and the gearbox is connected with the traveling wheels, and the gearbox is connected with the shallow tiller 5 and the deep tiller 6 through the gearbox at the same time. The axis of the knife shaft of the deep tillage knife 6 is located behind the axis of the knife shaft of the shallow tillage knife 5, and is shifted downward by a certain distance. This offset can vary the depth of deep plowing. the

The walking wheel 3 of the utility model and the shallow plowing knife 5 have the same rotation direction, and the shallow plowing knife 5 and the walking wheel 3 jointly provide the forward driving force for the deep plowing machine while cutting the soil on the cultivated land. The rotation direction of the deep tiller blade 6 is opposite to that of the shallow tiller blade 5, so that the horizontal component force of the reaction force produced by the soil on the deep tiller blade 6 is opposite to the forward direction of the deep tiller, so that the driving force of the deep tiller will not be too large, so as to facilitate deep plowing and control of the deep tiller. travel speed, while the machine runs smoothly. the

As shown in FIG. 2 , the lateral length of the deep tilling knife is smaller than that of the shallow tilling knife, so that the tilling width of the deep tilling knife is smaller than that of the shallow tilling knife. The transmission box 4 realizes the power transmission from the gearbox 1 to the shallow plowing blade 5 and the deep plowing blade 6, and the transmission mode can be chain transmission, gear transmission, shaft transmission, belt transmission and the like. the

The shallow plowing knife is composed of a left shallow plowing knife and a right shallow plowing knife that are symmetrically arranged on the left and right sides of the transmission box. Figure 2 shows. the

The effect of using this deep tiller to realize shallow soil plowing and deep loose layered cultivation in one operation is shown in Figure 3. The number 7 is the uncultivated land, the number 8 is the land after deep plowing, and the number 9 is the land after shallow plowing. the

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model. the
