The working principle of the utility model is briefly described as follows:

The utility model relates to a soil loosening and fertilizing micro tillage machine, which integrates the functions of loosening the soil and fertilizing.

1. The realization principle of soil loosening function

As shown in Figure 1, the gasoline engine 6 mounted on the frame 3 is connected with the worm of the worm reducer 2 through the centrifugal clutch 4, and the rotary blade group 1 is installed on the worm gear shaft of the worm reducer 2, and a small-scale high-power gasoline engine is adopted. The power is directly transmitted to the cultivating knife group through the centrifugal clutch and the worm reducer, so as to realize efficient soil loosening.

Centrifugal clutch 4 is made of centrifugal block and spring and driven friction disc, and spring overcomes the centrifugal force of centrifugal block when machine idles, and centrifugal block does not contact with driven friction disc, and transmission is separated. When the speed of the machine increases, the centrifugal force of the friction block overcomes the tension of the spring and contacts the driven friction disc, driving the driven shaft to rotate.

The rotary tiller group 1 consists of eight left-handed and right-handed altogether sixteen cultivators, which are staggeredly installed to ensure that the soil cutting force of the tiller group is balanced in the axial direction.

2. The realization principle of fertilization function

The realization of the fertilization function is to drive the driving gear 13, the transition gear 12, the driven gear 11, and the fertilization shaft 15 through the passive travel wheel 5, and then drive the rotation of the fertilizer roller 14 to realize the indirect drive. The fertilizer roller 14 rolls, and the fertilizer Enter the fertilizer tank 22 of the fertilizer roller 14 from above, and then be taken to the discharge port 16 below the fertilizer tank 7 by the fertilizer roller. Fig. 2 well shows the principle that the fertilizer roller 14 is indirectly driven.

Rocking bar 10 connects transition gear 12 and driven gear 11 together, makes these two gears become a whole, and rocking bar 10, connecting rod 19, clutch handle 20, frame 3 constitute crank rocker mechanism. Shown in Fig. 1 is the state during fertilization, pull down clutch handle 20 this moment, connecting rod 19 and clutch handle 20 collinear locking, transition gear 12 meshes with driving gear 13, can carry out normal fertilization at this moment, passive travel wheel 5 As long as it is rotated, fertilization can be carried out; Figure 3 shows the state when fertilization is stopped, pull up the clutch handle 20, the transition gear 12 is disengaged from the driving gear 13, at this time, the rotation of the passive travel wheel 5 no longer drives the fertilizer roller Tube 14 rolls, and fertilization stops.
