Embodiment 1

[0033] Embodiment 1: The stubble grinder of this embodiment is installed on the rear suspension of the tractor and is driven by the forward movement of the tractor to move forward, and is controlled to move up and down by the rear suspension of the tractor. Such as figure 1 As shown, the stubble grinder includes a suspension frame 3, which is fixedly installed on the rear suspension of the tractor, and can connect the hydraulic motor with the hydraulic oil tank device at the same time; the suspension frame is welded by a plurality of square tubes. Under the premise of meeting the requirements of use, choose a thin and small square tube as much as possible, which can effectively reduce the weight of the whole machine, thereby reducing energy consumption; a longitudinal crushing header is installed at the position below the front end of the suspension frame through the buffer mechanism 5 ,Such as figure 2 and Figure 6 As shown, the buffer mechanism 5 includes a buffer frame ...

Embodiment 2

[0041] Embodiment 2: The similarities between this embodiment and Embodiment 1 will not be described in detail. The difference is that in order to improve the crushing efficiency of the longitudinal crushing header, this embodiment is based on Embodiment 1. The front end of the front end is uniformly provided with sawtooth 18, which is helpful for the cutting table fixing plate to level the land while helping the saw blade to crush and effectively prevent the straw from clogging the saw blade during the advancing process; There are comb teeth 19 with different heights, and the comb teeth are located between adjacent saw blade groups and do not affect the opposite cutting of adjacent saw blades, which is beneficial to combing the stubble and facilitates the rotary cutting and crushing of the saw blades.

Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a novel wheat stubble crusher. The wheat stubble crusher comprises a suspension rack, a longitudinalcrushing header, a filtering rake, a transverse crushing rotary tillage mechanism, buffer mechanisms and a driving mechanism, wherein the suspension rack is directly mounted on a rear suspension of atractor and is controlled by the rear suspension to move up and down; the longitudinal crushing header is fixed to the front end of the suspension rack through the buffer mechanism, and a crushing saw blade is driven by a hydraulic motor to longitudinally crush wheat stubbles; and the transverse crushing rotary tillage mechanism is fixed to the rear end of the suspension rack through the buffer mechanism, the hydraulic motor drives a rotating shaft to transversely crush wheat stubbles which are not ideally crushed by the longitudinal crushing header, meanwhile wheat roots remaining in soil are excavated and crushed, and micro-tillage treatment is conducted on the soil while excavation is conducted. According to the wheat stubble crusher, longitudinal crushing and transverse crushing are combined, so that the effective crushing rate of the wheat stubbles can be increased, meanwhile, the energy loss caused by mechanical transmission can be effectively reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a novel wheat stubble grinder. Background technique [0002] Existing rotary tillage equipment mainly loosens the land, that is, crushes the rhizomes of crops while loosening the land, but the crushing effect is not ideal, and it is easy to cause the seeds to be in a fluffy state when sowing in the later stage, thereby affecting seed development and emergence rate. With the development of agricultural technology, people have higher and higher requirements for the land before sowing. For example, in order to effectively crush the wheat stubble before sowing the autumn peanuts, it is necessary to use a rotary tiller to perform multiple rotary tillage on the land, resulting in labor-intensive and time-consuming. , and the effect is not ideal. Moreover, the vertical shaft with the spiral cutter head of the existing rotary tiller is a suspended shaft, and t...
