The Whole Grain Straw Wheat Sowing Machine Using Straw Automatic Shunt Regulation

Abstract

The invention provides a full-stalk wheat planter capable of realizing straw automatic shunt regulation, wherein a frame is provided with a straw conveying auger, one end of the auger shaft is provided with a rolling bearing, the inner circle of the rolling bearing is connected with the hollow auger, and the outer circle and a disc are fixedly connected; a rack is arranged on the edge of one sideof the disc in the same axial direction as the disc, a plurality of springs are arranged on the end surface of the disc in the same direction as the rack, and the other end of each spring is fixed with the inner side of a side plate of the rack. A flat bevel gear is arranged beside the rack, the flat gear part of the flat bevel gear meshes with the rack, the bevel gear part of the flat bevel gearmeshes with a driven bevel gear fixed on the outer side of the frame side plate, the rotating shaft of the driven bevel gear is fixedly connected with one end of a baffle plate, and the other end of the baffle plate is hinged with the side plate of the frame. Before the operation, the split proportion is controlled by adjusting the ratio of the spring and the bevel gear; during the operation, theplanter automatically realizes a stepless regulation and control of the straw split according to the actual straw amount in the field, and the whole process does not need manual operation, and the time and labor are saved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a wheat seeder with full amount of straw that can realize the automatic diversion and control of straw. Background technique [0002] The wheat seeder with full amount of straw can complete straw crushing, cleaning and throwing, rotary tillage sowing, and straw mulching at one time without any treatment on the previous crop straw, which provides strong support for the fertilizer utilization of straw returning to the field and the realization of burning ban. However, when the previous stubble is rice, corn and other crops with a large amount of straw, excessive straw coverage will cause wheat seedling shortage and weak seedling situation, which will affect the yield. [0003] Patent No. 201410113918.7 "A No-tillage Wheat Planter with Adjustable Straw Coverage" discloses a no-tillage wheat planter with adjustable coverage, which can realize part of the straw into the soil and ...

AI Technical Summary

Problems solved by technology

[0005] 2. There are differences in the amount of straw in different fields, which requires the operator to adjust the insertion depth of the adjustment plate when changing the field operation, which is time-consuming and laborious, and it is difficult for the operator to judge the amount of straw in the field before operation, so adjust Quantity cannot be determined in advance

[0006] 3. When operating in a certain field, the distribution density of straw in the field is often uneven, and this technology can only divert the straw according to the ratio set before the operation, resulting in poor uniformity of straw coverage and failure to fully utilize straw coverage The effect of sowing

[0007] 4. The insertion depth of the adjustment plate is changed through limited screw holes, and the adjustment accuracy is poor
