Problems solved by technology

[0003] At present, the green manure turning machines used in China are all transformed from rotary tillers, which have problems such as low versatility, high energy consumption, especially poor turning green coverage, which leads to low green manure utilization efficiency, etc.
Moreover, due to the technical characteristics of the rotary tiller itself, there are some technical defects in the green manure turning and returning machine transformed from the rotary tiller, such as large disturbance to the soil, killing earthworms in the surface soil, high power consumption, and The soil is soft and difficult to control the sowing depth, etc.
[0004] In the past 20 to 30 years, domestic research on specialized green manure turning technology and machinery has almost stagnated, resulting in the lack of mature and universally applicable green manure mechanized turning technology and machinery. The green manure turning operation environment is harsh, low efficiency, high cost, The effect is poor, which seriously restricts the expansion of green manure planting scale

Embodiment 1

[0024] The design of the present embodiment is used for the paddy field green manure turning green device of green manure crops such as milk vetch.

[0025] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0026] according to figure 1 It can be seen that the green manure turning green device of this embodiment includes 3 groups of rotary soil cutting units and 3 groups of soil unloading and embedding units. The rotary soil cutting unit is connected to the knife seat outside the cutter head by bolts, and the knife seat is welded on the outside of the cutter head. The soil unloading and embedding unit is connected to the inner side of the cutterhead by bolts. The cutter head is connected with the cutter head flange through bolts; the cutter head flange is welded on the cutter shaft.

[0027] The rotary soil cutting unit includes 2 side knives and 1 horizontal knife. The edge of the side knife is in the shape of an A...

Embodiment 2

[0032] The design plowing depth of the greening device in this embodiment is 200mm, the soil cutting pitch is 150mm, the forward speed of the unit is 2.1Km / h, the rotational speed of the cutter shaft is 76r / min, the turning radius of the side cutter is 300mm, and the turning radius of the side plate is 240mm According to above-mentioned several parameters, can obtain by analyzing the fish cycloid of rotary graph cutting device, the installation angle between the rotary soil cutting unit in the present embodiment and unloading soil embedding green unit is 58 °; The included angle is 120°, and the implementation results show that the herringbone-shaped horizontal knife can also better complete the greening work when the included angle is 120°.

Embodiment 3

[0034] In this embodiment, the design plowing depth of the greening device is 200mm, the soil cutting pitch is 150mm, the unit advance speed is 2.1Km / h, the cutter shaft speed is 56r / min, the turning radius of the side cutter is 380mm, and the side plate The turning radius is 320mm. According to the above parameters, by analyzing the trochoid of the rotary cutting device, it can be obtained that the installation angle between the rotary soil cutting unit and the soil unloading and embedding unit in this embodiment is 40°. The side knives are straight knives, and the two side knives correspondingly installed on the two cutter heads are installed at an angle of 30°. The implementation results show that the greening work can be better completed after the cutter shaft speed is reduced.

[0035] The quantity of the rotary soil cutting unit and the soil unloading and embedding unit installed on each cutterhead of the present invention, and the axial distance between the flanges of ...

Abstract

The invention belongs to the technical field of agricultural tillage whole machinery, particularly relating to a rotary-cutting and turning type ploughing in green device of green manure, which comprises a rotary soil-cutting unit and a soil discharging and green burying unit, wherein, the rotary soil-cutting unit and the soil discharging and green burying unit are mounted with a certain angle therebetween; the rotary soil-cutting unit comprises two side cutters and a transverse cutter which is Y-shaped and the included angle of which is not larger than 170 degrees; and the soil discharging and green burying unit comprises two lateral plates and a top roll. The device is suitable for the ploughing in green operation of milk vetch, hairy vetch, common vetch, white clover, red clover and other green manure crops. Particularly, the rotary soil-cutting unit can cut the soil on which green manure crops grow into rectangular furrow slices, the furrow slices are turned over by 180 degrees under the auxiliary action of the soil discharging and green burying unit, thereby the green manure crops are buried into the soil, the spreadability of ploughing in green of the green manure is good, thereby the use ratio of the green manure is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural tillage machinery, and in particular relates to a green manure turning device. The device is suitable for turning green of green manure crops such as milk vetch, vetch, arrow pea, white clover, and red clover. Background technique [0002] The mechanized greening of green manure is the use of mechanical devices to turn up the soil, and then bury the fertilizer stems on the soil surface into the soil, and wait for a period of time to decompose in the soil, so as to increase soil fertility and improve soil microstructure the goal of. Turning green manure is a key production link for green manure plants to be converted into green manure. In order to improve the utilization effect of green manure, there are relatively strict requirements on the turnover period, depth of turnover, ambient temperature during turnover, and turnover quantity of green manure in agronomy. . For example, the turning ...
