Problems solved by technology

The active stubble cutting device has greatly improved the effect of cutting straw, but the active stubble cutting and anti-blocking devices currently used are unsupported cutting straws, so it is necessary to rotate the cutter head at a high speed of more than 1800 rpm to cut the straw. cut off
When working, the cutter often throws out the straw instead of cutting it, or presses the straw into the soil, so it cannot effectively prevent the straw from entanglement with the soil working parts
In addition, the high-speed rotation of the power knife is likely to cause a safety hazard in the work of the planter

Embodiment Construction

[0008] The specific structure of the present invention is given by the following examples. As shown in the figure, the active disc cutter is composed of a cutter head 5 and several blades 6, and the cutter shaft 2 drives the active disc cutter to rotate in the opposite direction to the forward direction of the machine through the wedge key 3. The passive disc cutter 1 is installed on the cutter shaft 2 through the rolling bearing 4, and the power of the cutter shaft 2 does not drive the passive disc cutter 1 to rotate, and the surface of the passive disc cutter and the active disc cutter are close together. During work, this device is installed on the front of the ditch opener of the no-tillage planter, and the passive disc cutter 1 has a depth of about 10cm in the soil under the gravity of the machine. As the machine advances and rotates in the same direction, the function of breaking soil and stubble is realized. The cutter shaft 2 is driven to rotate by the power of the tr...

Abstract

The invention main relates to an anti-blocking device of a no-tillage planter and provides a novel crop root cutting and breaking method by organic combination and application of an active crop root cutting and breaking method and a passive crop root cutting and breaking method. The anti-blocking device is mainly characterized in that a driving cutter disk and a driven cutter disk arranged on the same cutter shaft form a dual-disk counter-rotating power crop root cutting and breaking device. The driven cutter disk is installed on the cutter shaft through a bearing, is inserted into the soil for a certain depth in the action of machine gravity during the work, and is rotated forward along the forwarding of the machine to realize the functions of breaking the soil and breaking crop boots. The driving cutter disk is rotated reversely in the driving of the power of the cutter shaft and is tightly clung to the driven cutter disk surface; the rotating radius of the driving cutter disk is smaller than that of the driven cutter disk; when the anti-blocking device works, the driving cutter disk is not inserted into the soil, has the maximum rotating radius on the soil surface, and is combined with the driven cutter disk to support and shear straws, so that the straws in a planting region of the soil surface are sheared off easily, and a furrower and other soil working members can be effectively prevented from being wound and blocked by grass. In addition, the dual disks are rotated reversely, so that the driving cutter disk can be operated at a lower rotating speed, and the safety of the no-tillage planter in working is improved effectively. The crop root breaking and soil breaking functions of the driven cutter disk are beneficial to the furrowing and penetrating of the furrower, and therefore, soil disturbance quantity is reduced and the development of advantages of protective cultivation is facilitated.

Description

technical field [0001] The invention relates to an anti-blocking device for a no-tillage seeder, which belongs to the field of agricultural machinery. Background technique [0002] No-tillage seeder is a key tool for conservation tillage. In areas where wheat and corn are grown twice a year, when corn no-till sowing is implemented, there will be a large amount of crushed wheat straw and untreated wheat stubble in the sowing field, which will entangle and block the soil working parts of the planter, causing the planter to The quality of work is poor and the work efficiency is low. Therefore, an anti-blocking device needs to be added. At present, there are two main methods for preventing straw from entanglement and blocking soil working parts on no-tillage seeders at home and abroad: dividing stubble and cutting stubble. The method of dividing stubble is mainly to push the stubble away from the sowing belt, such as a grass dividing shovel, a grass dividing double disc, etc....
