Abstract
The utility model relates to fittings of agricultural machinery, in particular to a pack roll of a no- tillage fertilizer application seeding machine. The pack roll comprises a roll body, spike teeth are arranged on the surface of the roll body, and the axial center of the roll body is connected with a main shaft. The utility model can ensure the sowing depth to be consistent.
Description
Technical field
The utility model relates to a kind of accessory of agricultural machinery, relates in particular to the pack roller of no-tillage fertilizing and seeding machine.
Background technology
The wheat no-tillage seeding is that China determines the agricultural machanization new technology that emphasis is promoted at present; be characterized in behind the crops straw mincing and returning to the field; directly carry out seeding operation with no-tillage fertilizing and seeding machine, once finish rotary tillage stubble-cleaning, fertilizer deep placement, wheat cultivation, suppression multiple working procedure such as preserve soil moisture, spray insecticide, compare with traditional tillage method with tractor; has the minimizing operation procedure; save labor, cost-saving synergistic improves chemical fertilizer utilization ratio; the protection environment, advantage such as produce more food.
Existing no-tillage fertilizing and seeding machine is established rotary tillage mechanism, feed mechanism, fertilizer mechanism and suppression mechanism, and suppression mechanism is made up of 5 above circular arc press wheels, macro-axis.The effect of press wheel is a compacting table soil, reaches excess in the upper and deficiency in the lower, seed is contacted with soil well help seed sprouting, and control fertilizer, feed mechanism, realizes seeding, fertilising.And this press wheel also comes with some shortcomings at design aspect: 1, make sowing depth deep mixed.According to agriculture requirement, wheat cultivation degree of depth the best is 3cm, the darkest 5cm that is no more than when soil moisture content is relatively poor, if cross dark wheat emergence rate, tillering capacity is low, seedling is thin and weak.Be wide, narrow row and suppress the sowing of wheeled wheat no-tillage fertilizing, Gao Beilong, its wide behavior 28cm, narrow row is 12cm, the back of the body high 20-22cm in ridge, bottom of trench is down " U " shape, and wheat seeds are in the bottom of trench both sides, the wide 5cm of sown scope; Because bottom of trench is down " U " shape, the part wheat seeds are broadcast at bottom of trench during wheat cultivation, when seed level is 3cm, another part wheat seeds are then broadcast the intersection at bottom of trench and furrow bank, sowing depth is 5-8cm, if when the seed level of bottom of trench is 5cm, the seed level of bottom of trench and furrow bank intersection then is 7-10cm.Loosened soil on the high in addition back of the body ridge drops down down naturally through wind and weather, can further increase sowing depth.2, the moistening or face of land produces skidding and causes the disconnected ridge that is short of seedling press wheel not at ordinary times on the face of land easily, has brought certain influence to increases in grain production.
The utility model content
The purpose of this utility model provides a kind of pack roller of no-tillage fertilizing and seeding machine, and it can make the sowing depth unanimity.
For solving the problems of the technologies described above, the utility model comprises: roll body, and spike-tooth is established on the roll body surface, and the roll body axial centre connects macro-axis.
Described spike-tooth is 4 to 10 groups, 10 every group.
Distance between every group of spike-tooth equates
The utility model adopts the roll body of surfacing, makes no-tillage fertilizing and seeding machine sowing depth unanimity, and the face of land is smooth substantially, helps plant growth.The spike-tooth on roll body surface can stretch in the soil simultaneously, has increased the contact area of roll body and soil, thereby has avoided pack roller to skid, and has reduced the generation on the disconnected ridge that is short of seedling, and lays a good foundation for increases in grain production increase income.
Description of drawings
Fig. 1 is the structural representation of the 4th kind of embodiment of the utility model pack roller.
Fig. 2 is the figure of Fig. 1.
Embodiment
The pack roller of first kind of embodiment of the utility model: roll body 1 is cylindrical, length is 1850mm, diameter is 350mm, the surface of roller has the thick roll of steel plate pressure of 2mm to form, 4 groups of diameters of surface soldered are 12mm, and length is the spike-tooth 2 of 35mm, and every group of spike-tooth has 10, distance between every group of spike-tooth equates, pack roller axial centre welding macro-axis 3.Barrel length can be made according to the sown scope of no-tillage fertilizing and seeding machine.
The pack roller of second kind of embodiment of the utility model: roll body is cylindrical, length is 1850mm, diameter is 350mm, the surface of roller has the thick roll of steel plate pressure of 2mm to form, 5 groups of diameters of surface soldered are 12mm, and length is the spike-tooth of 35mm, and every group of spike-tooth has 10, distance between every group of spike-tooth equates, pack roller axial centre welding macro-axis.
The pack roller of the third embodiment of the utility model: roll body is cylindrical, length is 1850mm, diameter is 350mm, the surface of roller has the thick roll of steel plate pressure of 2mm to form, 6 groups of diameters of surface soldered are 12mm, and length is the spike-tooth of 35mm, and every group of spike-tooth has 10, distance between every group of spike-tooth equates, pack roller axial centre welding macro-axis.
The pack roller of the 4th kind of embodiment of the utility model as shown in Figure 1 and Figure 2: roll body is cylindrical, length is 1850mm, diameter is 350mm, the surface of roller has the thick roll of steel plate pressure of 2mm to form, 10 groups of diameters of surface soldered are 12mm, and length is the spike-tooth of 35mm, and every group of spike-tooth has 10, distance between every group of spike-tooth equates, pack roller axial centre welding macro-axis.
The utility model in use, need be installed on the frame at no-tillage fertilizing and seeding machine rear portion, the no-tillage fertilizing and seeding machine that drives along with tractor moves, with grading, thereby help plant growth, and by the spike-tooth increase roll body on roll body surface and the contact area of soil, thereby avoided pack roller to skid.
Claims (3)
1. the pack roller of a no-tillage fertilizing and seeding machine, it is characterized in that it comprises: roll body (1), roll body surface are established spike-tooth (2), and the roll body axial centre connects macro-axis (3).
2. the pack roller of no-tillage fertilizing and seeding machine according to claim 1 is characterized in that described spike-tooth is 4 to 10 groups, 10 every group.
