Problems solved by technology

However, the simple use of smooth UHMWPE materials cannot adjust the degree of soil compaction, so it needs to be made into a geometric structure surface to achieve adjustable soil compaction.

Embodiment 1

[0047]The specific structure of the rolling soil-touching parts of the bionic structure for processing the micro-topography of the soil surface in the field of ridge farming in this example is shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5 and Figure 6. The structural characteristics of the new rolling soil-contacting parts of this example are: it has the ridge roller 4 for suppressing the ridge and the furrow roller 7 for suppressing the furrow at the same time, which is different from the traditional suppression roller that can only suppress the ridge; There are roller teeth 3 and 6 with bionic geometric structure, which can process the micro-topography of the soil surface, which is different from the traditional pressure roller without teeth that cannot process the micro-topography of the soil surface; the surface of the ridge roller and the furrow roller has convex hulls, The bushing with bionic geometric structure of pits, ribs, steps and scales is made of UHMWP...

Embodiment 2

[0049] The specific structure of the rolling soil-touching parts of the micro-topography processing of the bionic structure in the ridge farming field soil surface in this example is shown in FIG. 8 . The biomimetic structure rolling soil-contacting parts for micro-topography processing of the field soil surface described in this example are different from Example 1 in that the rolling soil-contacting parts consist of 2 ridge rollers and 3 furrow rollers. The rest of the parts that are not described are the same as those described in Embodiment 1, and will not be repeated.

Embodiment 3

[0051] In this case, the specific structure of the furrow roller for the micro-topography processing of the soil surface in the ridge farming field is as follows: Figure 10 show. The difference between the furrow roller of the microtopography processing bionic structure rolling soil contacting parts in the ridge farming field described in this example and the example 1 and example 2 is that 8 roller teeth are distributed on each circumferential line of the furrow roller in this example, and each ridge The table roller or ditch roller axis is arranged with 3 rows of roller tooth groups. The other unmentioned parts are the same as those described in Embodiment 1 and Example 2, and will not be repeated.

Abstract

The invention belongs to agricultural machinery, in particular relates to a rolling soil-engaging part for compacting soil and changing soil surface microtopography after seeding in a ridge culture mode, and in particular relates to a ridge culture field soil surface microtopography processing bionic structure rolling soil-engaging part. The part mainly comprises ridge table rollers, ridge trenchrollers and a total frame, wherein a plurality of ridge table rollers and ridge trench rollers are arranged, are connected in series on the total frame through a ridge table roller frame and a ridge trench roller frame respectively and can rotate around the total frame; a ridge table roller bushing and a ridge trench roller bushing are arranged on the surfaces of the ridge table roller frame and the ridge trench roller frame; and ridge table roller teeth and ridge trench roller teeth having geometric structures are uniformly distributed on the circumferences of the surfaces of the ridge tablerollers and the ridge trench rollers. On the premise of guaranteeing a soil compaction function, the rolling resistance is reduced, the adhesion between the part and soil is reduced, soil microtopography is changed, and soil water storage and soil moisture conservation capacity and agro-ecology are improved; therefore, farmland resists severe weather conditions, and sustainable production increase capacity is improved.

Description

Technical field: [0001] The invention relates to a soil-contacting part of an agricultural machine, in particular to a rolling soil-contacting part for processing the micro-topography of the soil surface in a ridge field, and belongs to the field of agricultural machinery. Background technique: [0002] The pressure roller is a typical rolling soil-contacting part in agricultural machinery, which is used to compact the soil. Whether it is traditional tillage or conservation tillage, the degree of compaction of farmland soil is one of the important factors affecting crop yield; the micro-shape of the soil surface Surface processing can increase the specific surface area of ​​the ground surface, accelerate the rise of ground temperature, advance the progress of follow-up operations if necessary, accelerate seed germination, resist soil erosion, and reduce the impact of natural disasters and harsh weather conditions. Proper soil compaction and soil surface microtopography can i...
