阅读说明：本技术 一种小麦播种定粒距成穴轮 (Wheat seeding fixed-grain-distance hole forming wheel ) 是由 唐泽 张恒榜 于 2018-08-16 设计创作，主要内容包括：本发明公开一种小麦播种定粒距成穴轮,小区小麦育种播种需要小麦播种粒距在理论粒距的范围之内,由于小麦种子颗粒小,投种在种沟会发生弹跳现象,致使播种粒距很难达到理论粒距要求,本发明提供一种应用于小麦播种定粒距成穴轮,所述一种成穴轮工作表面均匀分布若干个三角形凸起部分,凸起部分用来压出等距的种穴,只要保证小麦种子投入相邻的种穴即可保证粒距合格率。(The invention discloses a hole forming wheel with fixed grain distance for wheat seeding, wherein the seed distance for wheat seeding is required to be within the range of theoretical grain distance for seeding wheat in a cell, and the seed throwing phenomenon can occur in a seed ditch due to small wheat seed particles, so that the seed distance for seeding can hardly reach the requirement of the theoretical grain distance.)

1. The utility model provides a be applied to wheat seeding fixed grain distance and become cave wheel which characterized in that: a plurality of triangular convex parts are uniformly distributed on the working surface of the cavitation wheel and are used for pressing out seed cavities with equal intervals.

Technical Field

The invention relates to the technical field of agricultural seeding machines, in particular to a fixed-grain-distance hole forming wheel for wheat seeding.

Background

The seeding of the wheat in the residential district requires that the grain spacing of the wheat seeding is within the range of the theoretical grain spacing, and the grain spacing is 0.5 to 1.5 times of the theoretical grain spacing and belongs to qualified grain spacing. Because the wheat seeds have small particles, the seeds are thrown in the seed furrows to bounce, so that the seeding grain distance is difficult to meet the requirement of the theoretical grain distance. At present, the wheat breeding and sowing in all colleges and universities mainly adopt an artificial breeding mode, and machines are not used, wherein the main reason is that the wheat sowing grain distance is not well controlled.

Therefore, the skilled person is working to develop a hole-forming wheel suitable for sowing wheat with fixed grain distance.

Disclosure of Invention

Based on the defects in the prior art, the technical problem solved by the invention is to provide a hole forming wheel suitable for wheat seeding with fixed grain distance.

In order to achieve the purpose, the invention provides a hole forming wheel applied to wheat seeding and with fixed grain distance.

The invention has the beneficial effects that: the invention is suitable for a hole forming wheel with fixed grain distance for wheat seeding, and can put wheat seeds into seed holes to avoid the problem of unqualified grain distance caused by the bounce of the wheat seeds in a seed ditch after seed throwing.

Drawings

FIG. 1 is an axial view of a wheat seeding hole-forming wheel with fixed grain distance.

FIG. 2 is a front view of a wheat seeding fixed-grain-distance hole forming wheel.

Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in figure 1, the wheat seeding fixed-grain-distance hole forming wheel is suitable for a wheat seeding fixed-grain-distance hole forming wheel, and a plurality of triangular convex parts are uniformly distributed on the working surface of the hole forming wheel and are used for pressing out equidistant seed holes.

When the invention is used, the furrow opener pulls the seed hole forming wheel to move forward, and the seed hole forming wheel rotates under the operation of soil to the force of the hole forming wheel, so that equidistant seed holes are pressed in the seed ditch by the seed hole forming wheel, and the qualified rate of the grain distance can be ensured as long as the wheat seeds are ensured to be thrown into the adjacent seed holes.
