Abstract

The utility model relates to a driving weeding wheel of a weeding loosener in seedlings, which belongs to a weeding operation component on agricultural machinery. An included angle between a tangent of an arc operation face arranged at the inner side of the outer end part of weeding teeth of the weeding wheel and the radial central line of the weeding teth is 15 to 23 DEG. A sphere head-shaped radius arranged at the outer end tip part of the weeding teeth is 1.5 to 4.5 mm, and the outer diameter of the weeding wheel is 400 to 450 mm. The structure parameter of the wheel is reasonably determined, and the utility model has the characteristics of good operation quality, high efficiency, low seedling damaging rate, few fault and wide accommodation. The utility model can be assembled on mechanical type tillage weeders with various types.

Description

The weed and loose soil machine driving type wheel of hoeing up weeds between seedling

Technical field

The utility model belongs to agricultural machinery intertill and clean tillage work tool, relates generally to the weeding operation part.

Background technology

The mechanical type extirpator is to use more cultivating equipment in China vast northern dry farming area, and the agricultural district that especially many people are few on ground uses more extensive.In recent years, for reducing the pollution to crops such as chemical fertilizer, agricultural chemicals, produce pollution-free food better, the mechanical type extirpator becomes the focus that people pay close attention to and use more.But, key operation parts on the existing extirpator wheel of hoeing up weeds, comprise servo-actuated rotary type hoe up weeds wheel and the driven in rotation formula wheel of hoeing up weeds, because its structural design and parameter are determined the problem of existence, the wheel of hoeing up weeds is often carried phenomenons such as soil block, stone, soil are buried the crop young plant, the tooth of hoeing up weeds winding straw, weeds during operation secretly, it is of poor quality to hoe up weeds, the seedling-damaging ratio height, and operating efficiency is low.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides between a kind of novel seedling the weed and loose soil machine driving type wheel of hoeing up weeds, and reaches the purpose that improves hoe up weeds between seedling operation quality and efficient, minimizing seedling-damaging ratio, reduction operation fault rate.

Basic design of the present utility model is that angle is 15 °-23 ° between the tangent line of the inboard camber line scope of operation in wheel hoe tooth outer end of hoeing up weeds and the hoe tooth radial centre lines; Hoe tip, tooth outer end is the bulb shape, and the bulb radius is the 1.5-4.5 millimeter; The wheel external diameter of hoeing up weeds is the 400-450 millimeter.

The utility model structural design and parameter determine that rationally the operation quality of hoeing up weeds is good, the efficient height, and seedling-damaging ratio is low, and the operation fault is few, and adaptability is good, can be fitted on all kinds mechanical type extirpator to use.

Description of drawings

Fig. 1 is the weed and loose soil machine driving type wheel construction schematic diagram of hoeing up weeds between seedling;

Fig. 2 is the side direction view of Fig. 1.

Piece number explanation among the figure:

1, hoe tooth, 2, the inboard camber line scope of operation.

Embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The weed and loose soil machine driving type wheel of hoeing up weeds between one seedling, the tangent line of the inboard camber line scope of operation 2 in hoe tooth 1 outer end with uproot that angle α is 15 °-23 ° between tooth 1 radial centre lines.Hoe tip, tooth 1 outer end is the bulb shape, and its bulb radius R is the 1.5-4.5 millimeter.The wheel outside dimension Φ that hoes up weeds is the 400-450 millimeter.

During use, the wheel assembly of as required this driving type raking wheel assembling all-in-one-piece being hoed up weeds, be fitted on the facility, external power drives and drives the wheel rotation of hoeing up weeds, driving is hoed up weeds and is taken turns outer lines speed and tractor-drawn speed of travel generation speed difference, makes the inboard camber line scope of operation 2 that drives the wheel of hoeing up weeds finish weeding operation between seedling.Soil block and stone are not carried in the epicycle operation secretly, do not bury seedling, straw winding and straw.

Claims

1, the weed and loose soil machine driving type wheel of hoeing up weeds between a seedling, the tangent line that it is characterized in that uprooting the inboard camber line scope of operation in tooth (1) outer end (2) with uproot that angle α is 15 °-23 ° between tooth (1) radial centre lines.

2, the weed and loose soil machine driving type wheel of hoeing up weeds between seedling according to claim 1 is characterized in that uprooting tooth (1) tip, outer end and is the bulb shape, and its bulb radius R is the 1.5-4.5 millimeter.

3, the weed and loose soil machine driving type wheel of hoeing up weeds between seedling according to claim 1, the wheel outside dimension Φ that it is characterized in that hoeing up weeds is the 400-450 millimeter.
